Dihydropyrimidine dehydrogenase deficiency and fluorouracil-related toxicity. (1/2974)

Dihydropyrimidine dehydrogenase (DPD) is the initial and rate-limiting enzyme of 5-fluorouracil (5-FU) catabolism. We report lymphocytic DPD data concerning a group of 53 patients (23 men, 30 women, mean age 58, range 36-73), treated by 5-FU-based chemotherapy in different French institutions and who developed unanticipated 5-FU-related toxicity. Lymphocyte samples (standard collection procedure) were sent to us for DPD determination (biochemical method). Among the whole group of 53 patients, 19 had a significant DPD deficiency (DD; below 150 fmol min(-1) mg(-1) protein, i.e. less than 70% of the mean value observed from previous population study). There was a greater majority of women in the DD group (15 out of 19, 79%) compared with the remaining 34 patients (15 out of 34, 44%, P<0.014). Toxicity was often severe, leading to patient death in two cases (both women). The toxicity score (sum of WHO grading, theoretical range 0-20) was twice as high in patients with marked DD (below 100 pmol min(-1) mg(-1) protein, n = 11, mean score = 13.2) compared with patients with moderate DD (between 150 and 100 pmol min(-1) mg(-1) protein, n = 8, mean score = 6.8), P = 0.008. In the DD group, there was a high frequency of neurotoxic syndromes (7 out of 19, 37%). The two deceased patients both had severe neurotoxicity. The occurrence of cardiac toxicity was relatively rare (1 out of 19, 5%). These data suggest that women are particularly prone to DPD deficiency and allow a more precise definition of the DD toxicity profile.  (+info)

Itraconazole oral solution as prophylaxis for fungal infections in neutropenic patients with hematologic malignancies: a randomized, placebo-controlled, double-blind, multicenter trial. GIMEMA Infection Program. Gruppo Italiano Malattie Ematologiche dell' Adulto. (2/2974)

To evaluate the efficacy and safety of itraconazole oral solution for preventing fungal infections, a randomized, placebo-controlled, double-blind, multicenter trial was conducted: 405 neutropenic patients with hematologic malignancies were randomly assigned to receive either itraconazole, 2.5 mg/kg every 12 hours (201 patients), or placebo (204 patients). Proven and suspected deep fungal infection occurred in 24% of itraconazole recipients and in 33% of placebo recipients, a difference of 9 percentage points (95% confidence interval [CI], 0.6% to 22.5%; P = .035). Fungemia due to Candida species was documented in 0.5% of itraconazole recipients and in 4% of placebo recipients, a difference of 3.5 percentage points (95% CI, 0.5% to 6%; P = .01). Deaths due to candidemia occurred in none of the itraconazole recipients compared with 4 placebo recipients, a difference of 2 percentage points (95% CI, 0.05% to 4%; P = .06). Aspergillus infection was documented in four itraconazole recipients (one death) and one placebo recipient (one death). Side effects causing drug interruption occurred in 18% of itraconazole recipients and 13% of placebo recipients. Itraconazole oral solution was well-tolerated and effectively prevented proven and suspected deep fungal infection as well as systemic infection and death due to Candida species.  (+info)

Randomized placebo-controlled trial of fluconazole prophylaxis for neutropenic cancer patients: benefit based on purpose and intensity of cytotoxic therapy. The Canadian Fluconazole Prophylaxis Study Group. (3/2974)

A randomized, double-blind trial comparing oral fluconazole (400 mg daily) with placebo as prophylaxis for adult patients receiving intensive cytotoxic therapy for acute leukemia or autologous bone marrow transplantation was conducted in 14 Canadian university-affiliated hospitals. Although fluconazole prophylaxis did not obviate the need for parenteral antifungal therapy compared with placebo (81 [57%] of 141 vs. 67 [50%] of 133, respectively), its use resulted in fewer superficial fungal infections (10 [7%] of 141 vs. 23 [18%] of 131, respectively; P = .02) and fewer definite and probable invasive fungal infections (9 vs. 32, respectively; P = .0001). Fluconazole recipients had fewer deaths attributable to definite invasive fungal infection (1 of 15 vs. 6 of 15, respectively; P = .04) and achieved more frequent success without fungal colonization (52 [37%] of 141 vs. 27 [20%] of 133, respectively; P = .004; relative risk reduction, 85%) than did placebo recipients. Patients benefiting the most from fluconazole prophylaxis included those with acute myeloid leukemia who were undergoing induction therapy with cytarabine plus anthracycline-based regimens and those receiving marrow autografts not supported with hematopoietic growth factors. Fluconazole prophylaxis reduces the incidence of superficial fungal infection and invasive fungal infection and fungal infection-related mortality among patients who are receiving intensive cytotoxic chemotherapy for remission induction.  (+info)

The evolution of antibiotic therapy for neutropenic patients. (4/2974)

Considerable progress has been made in the treatment of infections in neutropenic patients during the past three decades. A major contribution to this progress has been the discovery of effective new therapies and their prompt administration. Unfortunately, successful therapy of each important pathogen has resulted in the emergence of new pathogens, usually with unique patterns of antibiotic susceptibility. Unfortunately, antibiotic resistance has become an increasing threat in recent years, raising the possibility of infections that will be difficult to eradicate. Fortunately, there are new classes of antimicrobials that hold promise for therapeutic success in the future.  (+info)

Protein kinase C mediates experimental colitis in the rat. (5/2974)

Protein kinase C (PKC) plays an important role in the cell signal transduction of many physiological processes. In contrast to these physiological responses, increases in PKC activity have also been associated with inflammatory disease states, including ulcerative colitis. The objective of this study was to examine the role of PKC as a causative mediator in initiation of experimentally induced colitis in the rat. Colitis was induced in rats by intrarectal (0.6 ml) instillation of 2,4,6-trinitrobenzenesulfonic acid (TNBS; 75 mg/kg in 50% ethanol) or the PKC activator phorbol 12-myristate 13-acetate (PMA; 1.5-3.0 mg/kg in 20% ethanol). Gross and histological mucosal damage, mucosal neutrophil infiltration, mucosal PKC activity, and PKC protein content for PKC isoforms alpha, beta, delta, and epsilon were assessed 2 h to 14 days after an inflammatory challenge. Both PKC activity and mucosal injury increased significantly within 4 h of TNBS treatment. PKC activity was maximal at 7 days and declined at 14 days, whereas mucosal damage became maximal at 1 day and declined after 7 days. In contrast, neutrophil infiltration as assessed by myeloperoxidase activity only increased 12 h after TNBS treatment, became maximal 1 day after TNBS administration, and declined thereafter. PKCbeta, -delta, and -epsilon were increased in response to TNBS, whereas PKCalpha protein content was decreased. The PKC antagonists staurosporine and GF-109203X (25 ng/kg iv) reduced TNBS-induced changes in mucosal PKC activity and the degree of mucosal damage. In contrast, neutropenia induced by antineutrophil serum treatment did not significantly affect the degree of injury or mucosal PKC activity. Furthermore, activation of mucosal PKC activity with PMA also induced mucosal damage, which was also inhibited by pretreatment with a PKC antagonist. In conclusion, these results suggest that increases in PKC activity play a causative role in TNBS-induced colitis. The PKC-mediated response to TNBS does not appear to involve neutrophil infiltration.  (+info)

A phase I study of the lipophilic thymidylate synthase inhibitor Thymitaq (nolatrexed dihydrochloride) given by 10-day oral administration. (6/2974)

2-Amino-3,4-dihydro-6-methyl-4-oxo-5-(4-pyridylthio)-quinazoline dihydrochloride (nolatrexed dihydrochloride, Thymitaq, AG337), a specific inhibitor of thymidylate synthase, was developed using protein structure-based drug design. Intravenously administered nolatrexed is active clinically. As oral bioavailability is high (70-100%), nolatrexed was administered orally, 6 hourly for 10 days, at 3-week intervals, and dose escalated from 80 to 572 mg m(-2) day(-1) in 23 patients. Common toxicity criteria (CTC) grade 3 toxicities included nausea, vomiting, stomatitis and liver function test (LFT) abnormalities. Thrombocytopenia (grade 1 or 2) occurred at doses > or = 318 mg m(-2) day(-1) and neutropenia (grade 2) at 429 and 572 mg m(-2) day(-1). An erythematous maculopapular rash occurred at dosages > or = 318 mg m(-2) day(-1) (7 out of 19 patients). LFT abnormalities occurred in two out of six patients (grade 3 or 4 bilirubin and grade 3 alanine transaminase) at 572 mg m(-2) day(-1). Nolatrexed plasma concentrations 1 h after dosing were 6-16 microg ml(-1), and trough 3-8 microg ml(-1), at 572 mg m(-2) day(-1). Inhibition of thymidylate synthase was demonstrated by elevation of plasma deoxyuridine. Six-hourly oral nolatrexed for 10 days was associated with antiproliferative effects, but nausea and vomiting was dose limiting at 572 mg m(-2) day(-1). Nine patients were treated at 429 mg m(-2) day(-1); three out of nine experienced grade 3 nausea, but 17 out of 22 treatment courses were completed (with the co-administration of prophylactic antiemetics) and this dose level could be considered for phase II testing.  (+info)

Phase I and pharmacologic study of the combination of paclitaxel, cisplatin, and topotecan administered intravenously every 21 days as first-line therapy in patients with advanced ovarian cancer. (7/2974)

PURPOSE: To evaluate the feasibility of administering topotecan in combination with paclitaxel and cisplatin without and with granulocyte colony-stimulating factor (G-CSF) support as first-line chemotherapy in women with incompletely resected stage III and stage IV ovarian carcinoma. PATIENTS AND METHODS: Starting doses were paclitaxel 110 mg/m2 administered over 24 hours (day 1), followed by cisplatin 50 mg/m2 over 3 hours (day 2) and topotecan 0.3 mg/m2/d over 30 minutes for 5 consecutive days (days 2 to 6). Treatment was repeated every 3 weeks. After encountering dose-limiting toxicities (DLTs) without G-CSF support, the maximum-tolerated dose was defined as 5 microg/kg of G-CSF subcutaneously starting on day 6. RESULTS: Twenty-one patients received a total of 116 courses at four different dose levels. The DLT was neutropenia. At the first dose level, all six patients experienced grade 4 myelosuppression. G-CSF support permitted further dose escalation of cisplatin and topotecan. Nonhematologic toxicities, primarily fatigue, nausea/vomiting, and neurosensory neuropathy, were observed but were generally mild. Of 15 patients assessable for response, nine had a complete response, four achieved a partial response, and two had stable disease. CONCLUSION: Neutropenia was the DLT of this combination of paclitaxel, cisplatin, and topotecan. The recommended phase II dose is paclitaxel 110 mg/m2 (day 1), followed by cisplatin 75 mg/m2 (day 2) and topotecan 0.3 mg/m2/d (days 2 to 6) with G-CSF support repeated every 3 weeks.  (+info)

Pneumonia in febrile neutropenic patients and in bone marrow and blood stem-cell transplant recipients: use of high-resolution computed tomography. (8/2974)

PURPOSE: To obtain statistical data on the use of high-resolution computed tomography (HRCT) for early detection of pneumonia in febrile neutropenic patients with unknown focus of infection. MATERIALS AND METHODS: One hundred eighty-eight HRCT studies were performed prospectively in 112 neutropenic patients with fever of unknown origin persisting for more than 48 hours despite empiric antibiotic treatment. Fifty-four of these studies were performed in transplant recipients. All patients had normal chest roentgenograms. If pneumonia was detected by HRCT, guided bronchoalveolar lavage was recommended. Evidence of pneumonia on chest roentgenograms during follow-up and micro-organisms detected during follow-up were regarded as documentation of pneumonia. RESULTS: Of the 188 HRCT studies, 112 (60%) showed pneumonia and 76 were normal. Documentation of pneumonia was possible in 61 cases by chest roentgenography or micro-organism detection (54%) (P < 10(-6)). Sensitivity of HRCT was 87% (88% in transplant recipients), specificity was 57% (67%), and the negative predictive value was 88% (97%). A time gain of 5 days was achieved by the additional use of HRCT compared to an exclusive use of chest roentgenography. CONCLUSION: The high frequency of inflammatory pulmonary disease after a suspicious HRCT scan (> 50%) proves that pneumonia is not excluded by a normal chest roentgenogram. Given the significantly longer duration of febrile episodes in transplant recipients, HRCT findings are particularly relevant in this subgroup. Patients with normal HRCT scans, particularly transplant recipients, have a low risk of pneumonia during follow-up. All neutropenic patients with fever of unknown origin and normal chest roentgenograms should undergo HRCT.  (+info)

Severe chronic neutropenia (SCN) is defined as an absolute neutrophil (ANC) of less than 0.5 x 10(9)/L, lasting for months or years. Congenital, cyclic, and idiopathic neutropenia are principal categories of SCN. Since 1994, the Severe Chronic Neutropenia International Registry (SCNIR) has collected data to monitor the clinical course, treatments, and disease outcomes for SCN patients. This report summarizes data for 853 patients, almost all treated with daily or alternate-day recombinant human granulocyte colony-stimulating factor (G-CSF or Filgrastim). G-CSF treatment increased the ANC overall from 0.34 x 10(9)/L +/- 0.018 pre-treatment to 3.70 x 10(9)/L +/- 0.18 during the first year of treatment. For most patients, the responses were durable with patients remaining on the same dose of G-CSF for many years. Long-term hematological observations showed stable mean leukocyte and neutrophil counts and gradually increasing hemoglobin levels. Thrombocytopenia developed in 4% of patients. As of ...
Severe chronic neutropenia may be present at birth (congenital neutropenia) or may occur at any stage in life (acquired neutropenia). There are four main types of severe chronic neutropenia:. Congenital Neutropenia - a rare inherited form of the disease usually detected soon after birth. It affects children mainly and may result in premature loss of teeth and peremptory gum infections. The most severe form of chronic congenital neutropenia is known as Kostmanns Syndrome.. Cyclic Neutropenia - tends to occur every three weeks and lasting three to six days at a time due to changing rates of cell production by the bone marrow. It is often present among several members of the same family although improves after puberty in most cases. This is the rarest form of severe chronic neutropenia.. Idiopathic Neutropenia - a rare form of neutropenia which develops in children and adults usually in response to an illness. It is diagnosed when the disorder cannot be attributed to any other diseases and often ...
The European branch of the SCNIR is actively cooperating with pediatricians and hematologists all over Europe. Since December 2001 the activities of the European neutropenia network are being supported by a grant of the European Commission in the program Rare Diseases. Thanks to the funding of the EU Commission, an Internet-accessible database system was acquired that enables all centers participating in the SCNIR to get the most pertinent information on severe chronic neutropenia directly via the Internet.. The SCNIR collects both, general and specific clinical information, e.g. on malignant transformation, bone marrow transplantation and outcome etc., on patients with severe chronic neutropenia. All information arising from the database of the European Branch of the Severe Chronic Neutropenia International Registry is disseminated among the members of this network in order to provide an update of the professional skills of the European network partners, which in turn is passed on to other ...

Autoimmune neutropenia is a form of neutropenia which is most common in infants and young children where the body identifies the neutrophils as enemies and makes antibody to destroy them. Primary autoimmune neutropenia (AIN) is an autoimmune disease first reported in 1975 that primarily occurs in infancy. In autoimmune neutropenia, the immune system produces autoantibodies directed against the neutrophilic protein antigens in white blood cells known as granulocytic neutrophils (granulocytes, segmented neutrophils, segs, polysegmented neutrophils, polys). These antibodies destroy granulocytic neutrophils. Consequently, patients with autoimmune neutropenia have low levels of granulocytic neutrophilic white blood cells causing a condition of neutropenia. Neutropenia causes an increased risk of infection from organisms that the body could normally fight easily. Who is Affected? Primary autoimmune neutropenia has been reported as early as the second month of life although most cases are diagnosed in ...

We describe the first case of chronic neutropenia of 17 years duration following gold therapy in a 53-year-old woman given a 1-g course of gold therapy in 1965 for treatment of seropositive rheumatoid arthritis. Although she had a good response to the gold therapy, her originally normal leukocyte count fell to 1.2 x 10(9)/L. Over the subsequent 17 years, she required multiple hospitalizations for recurrent skin, mouth, and respiratory tract infections. Serial leukocyte counts failed to show a cyclical nature to the chronic neutropenia. Normal results of a technetium Tc 99m spleen scan and lack of increased bone marrow leukocyte precursors rendered a diagnosis of Feltys syndrome unlikely. A bone marrow biopsy specimen revealed an isolated reduction in the number of myeloid precursors, which is consistent with gold-induced bone marrow toxicity. This patients relative freedom from serious life-threatening infections remains enigmatic, but is undoubtedly related to her ability to augment another ...

Genetic Heterogeneity of Severe Congenital Neutropenia Severe congenital neutropenia is a genetically heterogeneous disorder showing autosomal dominant, autosomal recessive, and X-linked inheritance. Autosomal dominant SCN2 ({613107}) is caused by mutation in the protooncogene GFI1 ({600871}) on chromosome 1p22. Autosomal recessive SCN3 ({610738}) is caused by mutation in the HAX1 gene ({605998}) on 1q21.3; autosomal recessive SCN4 ({612541}) is caused by mutation in the G6PC3 gene ({611045}) on 17q21; autosomal recessive SCN5 ({615285}) is caused by mutation in the VPS45 gene ({610035}) on 1q; autosomal recessive SCN6 ({616022}) is caused by mutation in the JAGN1 gene ({616012}) on 3p25; and autosomal recessive SCN7 ({617014}) is caused by mutation in the CSF3R gene ({138971}) on 1p34. X-linked SCN (SCNX; {300299}) is caused by mutation in the WAS gene ({300392}) on Xp11. For associations pending confirmation, see MOLECULAR GENETICS.

Early misdiagnosis is a common issue for patients and families with Neutropenia. In order to officially determine Neutropenia a physician will need to run a Complete Blood Count (CBC), which is also known as a Full Blood Count (FBC). These procedures directly measure the neutrophil count.. Patients with Severe Chronic Neutropenia (SCN) may have a neutrophil count which varies slightly.. Though, in contrast to Cyclic Neutropenia it always remains at a very low level. With Cyclic Neutropenia counts can test normal due to a cyclical change, but may test very low at other times. Testing for Cyclic usually involves CBCs taken three times per week for at least six weeks to see if a regular cyclical pattern of neutrophil counts.. Physicians should also do a blood test to exclude autoimmune Neutropenia by testing for neutrophil antibodies.. ...
as cyclical neutropenia and Grey Collie Syndrome, is an inherited blood disorder that results due to an autosomal dominant cell mutating. This disorder causes extremely low neutrophil blood levels in the body. Neutrophils are better known as white blood cells and they aid the body in fighting off infections. With this recurring condition, it approximately occurs every three weeks, while lasting anywhere from three to six days. When neutrophil level are low, the pet may be prone to more frequent infections. Symptoms of cyclic neutropenia are joint pain, diarrhea, skin infections, mouth ulcers, fevers, and frequent infections. Collie dog breeds tend to be the most common breed that suffers from this condition. Unfortunately there is no current cure available for pets who suffer from cyclic neutropenia, however, there are some medications your veterinarian can prescribe that may prolong your cat or dogs life by several years..

11 patients with chronic neutropenia were evaluated. In 6 patients low numbers of CFU-DG were observed. Only 3 of these patients also had low CFU-C numbers, suggesting that these two precursors are not identical. Bone marrow samples from 2 patients were restudied a year later. The number of CFU-DG remained low while CFU-C numbers increased to control range in 1 patient. Studies for serum inhibitors were negative. No cytogenetic abnormalities were observed. This study suggests that abnormalities at different levels in the haemopoietic precursor cell hierarchy can be detected either simultaneously or independently in patients with chronic neutropenia. ...

We retrospectively compared the incidence of neutropenia in two groups of HIV patients with lymphoma, who underwent chemotherapy supported by once-per-cycle administration of pegfilgrastim or by daily subcutaneous injection of filgrastim, respectively. Our findings indicate that pegfilgrastim and filgastrim produce similar results in preventing both neutropenia and febrile neutropenia.
Neutropenia is the decrease to the normal Neutrophil count. Neutropenia is defined as the Neutrophil count that less than 2,500 cells/µL.. The normal white blood cell count for the Neutrophil is 8870 segmental (mature) cells/µL in newborns which drops down dramatically within 2 weeks to lower than 2600 cells/µL, then the normal Neutrophil count starts to increase again to reach 3800 cells/µL in adults.. Since the Neutrophil makes up the majority of white blood cells, except at early childhood, a massive decrease in the Neutrophils count (severe Neutropenia) would cause a noticeable decrease in the total blood cells count (Leukopenia) and sometimes the terms Neutropenia and Leukopenia may be used to refer to each other. But Neutropenia is just a subtype of Leukopenia.. Neutrophils are decreased in the circulating blood by exposure to radiation and Neutropenia is considered as a side effect to Radiation Therapy.. Anaphylactic reaction (Anaphylaxis) is another cause of Neutropenia. Anaphylaxis ...
Christoph Klein and colleagues identify homozygous mutations in the JAGN1 gene in families and individuals with severe congenital neutropenia. They show that JAGN1 is necessary for the differentiation and survival of neutrophil granulocytes. The analysis of individuals with severe congenital neutropenia (SCN) may shed light on the delicate balance of factors controlling the differentiation, maintenance and decay of neutrophils. We identify 9 distinct homozygous mutations in the JAGN1 gene encoding Jagunal homolog 1 in 14 individuals with SCN. JAGN1-mutant granulocytes are characterized by ultrastructural defects, a paucity of granules, aberrant N-glycosylation of multiple proteins and increased incidence of apoptosis. JAGN1 participates in the secretory pathway and is required for granulocyte colony-stimulating factor receptor-mediated signaling. JAGN1 emerges as a factor that is necessary in the differentiation and survival of neutrophils.
Neutropenia is an absolute decrease in the number of circulating neutrophils in the blood which results in susceptibility to severe pyogenic infections. Various oral findings such as periodontitis, alveolar bone loss and ulceration may be seen in neutropenic patients. A case is presented of a 6 year old girl with chronic, probably congenital, severe neutropenia with frequent respiratory tract infections, recurrent oral ulcerations and significant periodontal breakdown resembling prepubertal periodontitis. She was given granulocyte-colony stimulating factor (G-CSF) treatment which resulted in an increase in granulocyte count within two weeks and resolution of the neutropenic ulceration. It is suggested that G-CSF together with dental care regimens is a promising treatment model in chronic severe neutropenia cases presenting with oral manifestations. ...

Thousands of people each year are hospitalized for neutropenia, which continues to cause substantial morbidity and mortality for those affected. Neutropenia is primarily caused by chemotherapy and various other cancer treatments, such as radiation therapy, biotherapy, and HSC transplantation. Signs and symptoms of neutropenia may include high fever, chills, sore throat, and diarrhea. In neutropenia, the number of neutrophils, a type of granulocyte, is greatly reduced, weakening the bodys immune system and increasing the risk of infection. Therefore, a method to provide adequate numbers of functional granulocytes to people with neutropenia could be of greatest benefit for recovery. Administration of a combination of two drugs, granulocyte colony-stimulating factor (G-CSF) and dexamethasone, has been show to stimulate the body to produce a large number of granulocytes. Granulocyte transfusions obtained from donors who have received these two drugs may help people with low white blood cell counts ...
Neutropenia or neutropaenia is an abnormally low concentration of neutrophils (a type of white blood cell) in the blood. Neutrophils make up the majority of circulating white blood cells and serve as the primary defense against infections by destroying bacteria, bacterial fragments and immunoglobulin-bound viruses in the blood. Patients with neutropenia are more susceptible to bacterial infections and, without prompt medical attention, the condition may become life-threatening (neutropenic sepsis). Neutropenia can be acute (temporary) or chronic (long lasting). The term is sometimes used interchangeably with leukopenia (deficit in the number of white blood cells). Signs and symptoms of neutropenia include fever, painful swallowing, gingival pain, skin abscesses, and otitis. These symptoms may exist because individuals with neutropenia often have infection Children may show signs of irritability, and poor feeding. Additionally, hypotension has also been observed in individuals who suffer from ...

The aim of this study was to determine predictive factors for neutropenia after docetaxel-based systemic chemotherapy in patients with castration-resistant prostate cancer (CRPC). The study included 40 Korean CRPC patients who were treated with several cycles of docetaxel plus prednisolone from May 2005 to May 2012. Patients were evaluated for neutropenia risk factors and for the incidence of neutropenia. In this study, nine out of forty patients (22.5%) developed neutropenia during the first cycle of docetaxel-based systemic chemotherapy. Four experienced grade 2, three grade 3, and one grade 4 neutropenia. Multivariate analysis showed that pretreatment white blood cell (WBC) count (p=0.042), pretreatment neutrophil count (p=0.015), pretreatment serum creatinine level (p=0.027), and pretreatment serum albumin level (p=0.017) were significant predictive factors for neutropenia. In conclusion, pretreatment WBC counts, neutrophil counts, serum creatinine levels, and serum albumin levels proved to be

Definition, Etiology, PathogenesisTop. Neutropenia is the most common hematologic complication of cancer treatment. It may result from the myelotoxic effects of chemotherapy or radiation therapy or from bone marrow infiltration by malignant cells. In patients with febrile neutropenia the causative pathogen can be identified only in 20% to 30% of cases. Prior to the introduction of empiric therapy for febrile neutropenia, the most frequently identified etiologic agents were Pseudomonas spp and Enterobacteriaceae (eg, Escherichia coli, Klebsiella spp) followed by gram-positive cocci (most commonly Staphylococcus aureus). In the era of empiric therapy, there has been a shift in the microbiology of pathogens to predominantly gram-positive organisms (coagulase-negative staphylococci being the most common) followed by Enterobacteriaceae and then by nonfermenting gram-negative bacilli, such as Pseudomonas aeruginosa.. Febrile neutropenia is defined as: 1) Oral temperature ≥38.3 degrees Celsius in a ...
Typhlitis describes enterocolitis of the ileocaecal region seen commonly in neutropenic patients.

This cohort offers new information about the hematological and infectious profiles of WS. Interestingly, besides the constant neutropenia and lymphopenia, all 8 patients present monocytopenia and half of the patients present profound monocytopenia below 0.1 G/L, contrasting with the monocytosis commonly observed in other congenital neutropenias, such as the elastase neutrophil expressed (ELANE) syndrome. Of particular note, susceptibility to mycobacterial infections may be added to the infection spectrum of WS. Considering the monocytopenia and the infectious profile, composed by pyogenic infections, warts and mycobacteria, WS presents certain similarities with the Mono-MAC syndrome, now identified as the consequence of GATA2 mutations[53, 54]. The major phenotypic difference between the two syndromes is the BM myelokathexis feature the WS..

The risk is calculated not only by the neutrophil count but by complicating factors as follows:. - The longer the duration of severe neutropenia, the greater the risk of infection.. - The risk of infection is greater when the count is falling rapidly or when there is associated monocytopenia, lymphocytopenia, or hypogammaglobulinemia.. - Neutropenia caused by disorders of hematopoietic progenitor cells (eg, chemotherapy-induced marrow suppression, severe inherited neutropenia) generally results in a greater susceptibility to infections compared with neutropenia resulting from accelerated turnover (eg, immune neutropenia).. - Integrity of the skin and mucous membranes, blood supply to tissues, presence of an indwelling catheter, and nutritional status are also important in considering infection risk.. ...
Febrile neutropenia occurs in compromised immune systems due to a low number of leukocytes, especially granulocytes. Patients with a declining number of granulocytes after chemotherapy, can during bacterial sepsis, quickly develop extensive neutropenia and become critically ill. Febrile neutropenia can be a life-threatening condition.. A patient with neutropenia and simultaneous fever or clinical suspicion of systemic infection should be treated as quickly as possible with broad spectrum antibiotics including gram-negative and gram-positive coverage as soon as the required microbiological samples are taken.. The clinical situation is most critical in patients who have not yet started antibiotic treatment. When broad-spectrum antibiotic treatment is started, monitoring the fever may be permitted. Fever is often the only symptom. Some have septicemia without fever. One should therefore also be aware of other symptoms such as lethargia, diarrhea, or visible sign of infection. The local clinical ...
Once-daily dose administration of aminoglycoside in adults is effective and economical. However, its value in febrile neutropenic children, especially in Thailand, is less well researched. In the area where Pseudomonas aeruginosa prevalence in febrile neutropenic children is low, the combination of cloxacillin and amikacin is an appropriate approach.

Although a number of antifungal agents are currently available, the need remains for effective but less toxic alternatives for this indication. We therefore conducted a phase 2 study of micafungin for 80 patients with hematologic diseases who were suffering from persistent or recurrent fever after at least 96 h of antibacterial therapy. The patients ...
Individuals with severe forms of congenital neutropenia suffer from recurrent infections. The therapeutic use of recombinant human granulocyte colony-stimulating factor (rhG-CSF) to increase the neutrophil count is associated with fewer infections and an improved quality of life. However, the long-term effects of this new therapy are largely unknown. In particular, it is unclear if myeloid leukemia, a known complication of some forms of congenital neutropenia, will occur with increased frequency among patients who receive long-term treatment with hematopoietic growth factors. We report 13 patients with congenital disorders of myelopoiesis who developed leukemic transformation with either myelodysplastic syndrome (MDS) or acute myelogenous leukemia (AML) and 1 who acquired a clonal cytogenetic abnormality without evidence of MDS or AML while receiving rhG-CSF. The bone marrows of 10 patients showed monosomy 7 and 5 had activating RAS mutations. These abnormalities were not detected in ...
TY - JOUR. T1 - Early hospital discharge of children with cancer treated for fever and neutropenia. T2 - Identification and management of the low-risk patient. AU - Mullen, Craig A.. AU - Buchanan, George R.. PY - 1990/1/1. Y1 - 1990/1/1. N2 - Children with leukemia and solid tumors are often hospitalized for empiric broad-spectrum antibiotic therapy because of fever during periods of chemotherapy-induced neutropenia. Conventional practice dictates that parenteral antibiotics be continued until the patient is afebrile and has recovered from neutropenia, ie, until the absolute neutrophil count (ANC) exceeds 500 cells per cubic millimeter. However, the practice in our center has been to discontinue parenteral antibiotic therapy and discharge many such patients before resolution of neutropenia. Since the feasibility and safety of this approach has not been studied, we reviewed the records of 114 consecutive hospitalizations for fever and neutropenia in 61 patients during a 13-month period. ...

However, it has not been reported in association with multiple myeloma (MM). We report a case of AIN in a patient with MM who also had a population of small lymphocytes with T-cell receptor gamma chain gene rearrangements. We also review other autoimmune manifestations of MM, the role of T-cell receptor gene rearrangement in AIN, and the implications of ...
Background: Pegfilgrastim (Peg-GCSF) is administered at the completion of chemotherapy to shorten the time that patients are neutropenic. Several adult studies reveal a higher risk of febrile neutropenia among patients who received Peg-GCSF within 24 hours of completing chemotherapy compared to those who received growth factor on days 2-4 after chemotherapy, while other studies show no increased risk or are inconclusive. Currently, there are no data in pediatric malignancies that evaluate the effect of timing of Peg-GCSF administration on the rates of febrile neutropenia. Objective: To determine if there was a difference in the incidence of febrile neutropenia when Peg-GCSF was administered within 24 hours or greater than 24 hours after completion of chemotherapy. Methods: An IRB-approved retrospective study was conducted at Arkansas Childrens Hospital. Medical records of patients who received Peg-GCSF after chemotherapy from 2010-2017 were analyzed. Eligible patients were those with a diagnosis of

AU - Mangoni, L.. AU - Cottafavi, L.. AU - Caramatti, C.. AU - Almici, C.. AU - Rizzoli, V.. PY - 1995. Y1 - 1995. N2 - In this study, nine patients with non-Hodgkins lymphoma (n=6) and Hodgkins disease (n=3) receiving different cytotoxic chemotherapy regimens were given granulocyte colony-stimulating factor (C-CSF) (5 μg/kg/day) from 48 hours after the end of chemotherapy to 48 hours before the next chemotherapy administration. The decrease in mean absolute neutrophil counts (ANC) and in mean platelet (Plt) counts was not significant when pre-therapy counts were compared with posttherapy ones (p ,0.375 and p , 0.4, respectively). The mean actual dose intensity was 92% (range 68-100%). G-CSF treatment after chemotherapy reduces neutropenia and permits administration of the full chemotherapy program. A ...
During the period of neutropenia due to chemotherapy, patients have high risk of infections. The use of antibiotic prophylaxis to reduce neutropenia-related complications in oncologic patients is still disputed. Recent meta-analysis and clinical trials demonstrated that antibiotic prophylaxis with chinolons reduces fever episodes, bacterial infections and mortality in adult oncologic patients with neutropenia due to chemotherapy for acute leukaemia. In paediatric patients, the only randomized, double-blind, prospective study up till now suggested that Amoxicillin clavulanate may represent an effective prophylactic treatment to reduce fever and infections in oncologic children with neutropenia, with an efficacy statistically demonstrated only in patients with acute leukaemia. Considering the risk of resistances, antibiotic-prophylaxis should be used only in selected patients ...

Secondary forms of AIN have some distinguishing features. First, in secondary AIN antineutrophil antibodies are usually only one of the causes of the neutropenia, which may be associated (depending on the case) with peripheral sequestration, bone marrow inhibition, or apoptosis (see below). Second, in most cases of secondary AIN the target of the autoantibodies is unknown. Third, these cases quite commonly also present with thrombocytopenia and/or haemolytic anaemia, and they may also have functional defects of phagocytes in the absence of neutropenia [41-43]. Finally, in most of these situations therapy for the cytopenia is the same as - or at least includes - treatment for the underlying disease.. The systemic autoimmune diseases most often seen together with AIN include rheumatoid arthritis (i.e. Feltys syndrome) and SLE. There is also a complex haematological condition known as large granular lymphocyte (LGL) syndrome, which closely resembles Feltys syndrome clinically. The fact that AIN ...

Key clinical point: The incidence of late-onset neutropenia proved higher than previously found in rituximab-treated patients with autoimmune diseases.Major finding: At 1, 2, and 5 years of continuous B-cell depletion, the incidence of late-onset neutropenia was 6.6% (95% confidence interval, 5.0%-8.7%), 7.9% (95% CI, 6.1%-10.2%), and 13.5% (95% CI, 10.4%-17.4%), respectively.Study details: A retrospective cohort study of 738 patients with various autoimmune diseases who were treated with rituximab.
In a study reported in the Journal of Oncology Practice, Keng et al at Cleveland Clinic found that institution of an emergency department febrile neutropenia pathway for patients with cancer reduced the time to antibiotic administration compared with historical and direct admission cohorts.. The study included all adult patients with cancer who presented with fever to the Cleveland Clinic Emergency Department between June 2012 and June 2013. The febrile neutropenia pathway interventions included providing patients with febrile neutropenia alert cards, standardizing the definition of febrile neutropenia and recognizing it as a distinct chief complaint, revising the emergency department triage level for febrile neutropenia, creating electronic febrile neutropenia order sets, administering empiric antibiotics before neutrophil count result, and relocating febrile neutropenia antibiotics to the emergency department. The primary outcome was time to antibiotic administration, with a target of 90 ...
The treatment of neutropenia itself depends on its cause and severity. Drugs that may cause neutropenia can be stopped whenever possible and exposures to infections or suspected toxins can be avoided. If an underlying disease has caused the neutropenia, treatment of the disease will then impact treating the neutropenia.. Special medications can be used to help bone marrow regenerate new neutrophils, according to Corey Cutler, MD, MPH, director of the Stem Cell Survivorship Clinic at Dana-Farber. These medications, called Growth Factors, are hormones that are naturally produced by the body. In certain situations, these medications can be used to help the body regenerate neutrophils and other white blood cells. ...

Antifungal prophylaxis with an oral triazole or parenteral echinocandin is recommended for patients who are at risk for profound, protracted neutropenia, such as most patients with acute myeloid leukemia/myelodysplastic syndromes or HSCT. Antifungal prophylaxis is not routinely recommended for patients with solid tumors. Additional distinctions between recommendations for invasive candidiasis and invasive mold infection are provided within the full text of the guideline (evidence-based; evidence quality: intermediate; strength of recommendation: moderate).. ...
Transient neutropenia often accompanies viral infections (eg, early-stage infectious mononucleosis), and sepsis is a particularly serious cause of neutropenia. Neutropenia associated with common childhood viral diseases occurs during the first 1 to 2 days of illness and may persist for 3 to 8 days. It usually corresponds to a period of acute viremia and is related to virus-induced redistribution of neutrophils from the circulating to the marginal pool. Neutrophil sequestration may occur after viral tissue damage. Moderate to severe neutropenia may also be associated with a wide variety of other infections (see Table 135-2 ...

Background: Management of febrile neutropenic episodes (FE) is challenged by lacking microbiological and clinical documentation of infection. We aimed at evaluating the utility of monitoring blood procalcitonin (PCT) in FE for initial diagnosis of infection and reassessment in persistent fever. Methods: PCT kinetics was prospectively monitored in 194 consecutive FE (1771 blood samples): 65 microbiologically documented infections (MDI, 33.5%; 49 due to non-coagulase-negative staphylococci, non-CNS), 68 clinically documented infections (CDI, 35%; 39 deep-seated), and 61 fever of unexplained origin (FUO, 31.5%). Results: At fever onset median PCT was 190 pg/mL (range 30-26800), without significant difference among MDI, CDI and FUO. PCT peak occurred on day 2 after onset of fever: non-CNS-MDI/deep-seated-CDI (656, 80-86350) vs. FUO (205, 33-771; p,0.001). PCT ,500 pg/mL distinguished non-CNS-MDI/deep-seated-CDI from FUO with 56% sensitivity and 90% specificity. PCT was ,500 pg/ml in only 10% of FUO ...
The novel inflammatory marker procalcitonin (PCT) was assessed as an index of infection in patients with febrile neutropenia. Blood samples were obtained from 115 patients with febrile neutropenia for determination of PCT levels before onset of fever and daily until the resolution of fever. The median PCT level on the first day of fever was 8.23 ng/mL in patients with bacteremia, compared with 0.86 ng/mL in patients with localized bacterial infections (P = .017). The median PCT level on the first day of fever was 2.62 ng/mL in patients with severe sepsis, compared with 0.57 ng/mL in patients with clinically localized infections (P , .001). A dramatic decrease in PCT levels was documented after resolution of the infection; PCT levels were elevated when the infection worsened. Pronounced PCT levels were also found in patients with fever of unknown origin who were responding to antimicrobial chemotherapy, compared with those not responding to treatment with antibiotics. PCT levels were particularly ...

Feeling FEBRILE NEUTROPENIA while using Neurontin? FEBRILE NEUTROPENIA Causes, Patient Concerns and Latest Treatments and Neurontin Reports and Side Effects.
A biosimilar agent to pegfilgrastim was therapeutically equivalent and comparable to the reference agent in terms of efficacy and safety in the prevention of chemotherapy-induced neutropenia in patients with early stage breast cancer receiving chemotherapy.
CPT-11 (Campto, irinotecan) is a promising new agent in the treatment of advanced colorectal cancer. Its safety has been assessed in light of the results from recent European phase II studies. In a pivotal French study in which CPT-11 350 mg/m2 was administered once every 3 weeks, neutropenia and delayed diarrhoea were the major adverse events: transient neutropenia occurred in 80% of patients, and severe neutropenia and febrile neutropenia in 47 and 15%, respectively. Delayed diarrhoea occurred in 87% of patients, with 39% having severe (grade 3 or 4) diarrhoea and 16% requiring hospitalisation. None of these adverse events was cumulative. Results of a pilot study to elucidate the mechanism of CPT-11-induced delayed diarrhoea suggest that this toxicity has a secretory mechanism with an exudative component. Early appropriate management of delayed diarrhoea may improve the safety profile of CPT-11. Indeed, the safety profile of CPT-11 was clearly improved in a later (currently ongoing) pan-European study
Not enough neutrophils, neutrophils being a type of white blood cell (specifically a form of granulocyte) filled with neutrally-staining granules, tiny sacs of enzymes that help the cell to kill and digest microorganisms it has engulfed by phagocytosis. The mature neutrophil has a segmented nucleus (it is called a seg or poly) while the immature neutrophil has band-shape nucleus (it is called a band). The neutrophil has a lifespan of about 3 days. Neutropenia may be seen with viral infections and after radiotherapy and chemotherapy. Neutropenia lowers the immunologic barrier to bacterial and fungal infection. Granulocytopenia or, as it is also called, agranulocytosis results in a syndrome of frequent chronic bacterial infections of the skin, lungs, etc. Although agranulocytosis literally means no granulocytes, there may, in fact, be some granulocytes but too few of them, i.e. granulocytopenia. Granulocytopenia can be genetic and inherited or it can be acquired as, for example, an aspect of ...
Letter to the Editor. Sir: Severe neutropenia, defined as less than 0.5 × 109/L mature neutrophil cells, is a potentially life-threatening side effect with tricyclic antidepressants,1 but it also occurs with mirtazapine with an approximate risk of up to 1 in 1000. Here, we present a patient with a known idiopathic leukopenia and cross-intolerance between tricyclic antidepressants and mirtazapine who developed agranulocytosis with mirtazapine. After discontinuation of mirtazapine, she was safely treated with venlafaxine. ...
Invasive fungal infections (IFI) are life-threatening diseases that are of particular concern in specific debilitated or immunosuppressed populations. Invasive candidiasis (IC) is the most frequent of the IFI, being one of the major causes of nosocomial bloodstream infection and a feared complication in patients with recurrent gastrointestinal surgery or prolonged stay in the intensive-care unit [1,2]. Patients with hematological malignancies or prolonged chemotherapy-induced neutropenia, and those with allogeneic hematopoietic stem cell transplantation (allo-HSCT), represent the groups at highest risk for developing invasive aspergillosis (IA), which is associated with a high mortality rate despite the increasing availability of antifungal therapies [3,4]. An increasing incidence of IA has also been reported in non-neutropenic immunosuppressed populations such as solid-organ transplant recipients or steroid-treated patients with chronic pulmonary diseases [5]. Early diagnosis of IFI is crucial ...
HealthGene is the first diagnostic laboratory that has developed and offered the DNA test for Canine Cyclic Neutropenia (Gray Collie Syndrome).
Neutropenia can be minimised by a reduction in the chemotherapy dose or by increasing the time interval between each cycle. While this is a common practice in the treatment of metastatic breast cancer where the ultimate goal is palliation, it may come at a cost of reduced efficacy when employed in the adjuvant setting.. Bonadonna and Valagussa first demonstrated a dose-response effect in the adjuvant treatment of breast cancer in a retrospective review, and showed that delivery of ,85% of standard dose of chemotherapy results in compromised survival.(4) Prospective studies have also confirmed dose intensity and dose density (shortening the time interval between each cycle) to be important in optimising survival outcome in the adjuvant treatment of breast cancer.(5,6) Unfortunately, dose intensity and density are also associated with increased myelosuppression, and the resultant neutropenia is a major dose-limiting toxicity. The last decade has also seen the introduction of taxanes into clinical ...
The choice of empirical antibiotic therapy should depend, first, upon the local bacterial epidemiology and prevalent resistance patterns, which varies hugely around Europe (M. Mikulska, et al., 2013, submitted for publication), and, secondly, on patient-related factors, which may indicate the need for broader-spectrum coverage than for the generality of patients (Table 3). Although, in terms of efficacy, carbapenems are graded AI,14 they should be avoided as empirical agents in uncomplicated patients without risk factors for resistant bacteria, so as to preserve their activity for seriously-ill patients.. Situations in which specific de-escalation protocols should be used as an initial approach are summarized in Table 4. As colonization with resistant bacteria is a major predictive factor for infection with such bacteria, initial (at admission) and regular screening, once or twice weekly, for gastrointestinal colonization with these organisms should be considered in centers with a high ...
The cytokine Granulocyte Colony Stimulating Factor (G-CSF) treatment significantly improves the quality of life among patients with severe chronic neutropenia [Jones et al. JAMA 270: 1132-1133 (1993)]. The G-CSF is a potent endogenous trigger for the release of neutrophils from bone marrow stores and for their activation for enhanced antimicrobial activity. G-CSF has been widely evaluated in various pre-clinical models of acute illness, with generally promising results [Marshall J.C. Shock 24: 120-9 (2005)]. Due to its proven efficacy during chemotherapy cycles, the G-CSF is an important biopharmaceutical drug used in oncology. G-CSF has been cloned and expressed in various types of cells, e.g. microbial cells [Souza L.M. Science 232: 61-65 (1986); Hu Z.Y. et al. Zhongguo Shenghua Yaowu Zazhi (1999), 20: 55-57], yeast cells [Lasnik M.A. et al. Biotechnol. Bioeng. 81: 768-774 (2003); Lee S.M. et al. Korean patent KR 160934 BI 19981116], rice cells [Hong et al.

Children with cyclic neutropenia have a fairly non-serious disease (benign) where their white blood cell count becomes low for 3-5 days, every 14-35 days.
Clinical trials of recombinant biologic agents have resulted in new treatment options for hematologic, oncologic, and cardiologic disorders. These agents include the interferons, recombinant human erythropoietin (r-HuEPO), colony-stimulating factors (CSFs), interleukins (ILs), and tissue plasminogen activator (t-PA). Interferon alfa has proven efficacious in treating certain hematologic malignancies and solid tumors and has recently been indicated for acquired immunodeficiency syndrome (AIDS)-related Kaposis sarcoma. Treatment with r-HuEPO has relieved the chronic anemia of hemodialysis patients. Recombinant human granulocyte CSF (G-CSF) or human granulocyte macrophage CSF (GM-CSF) has been used to treat patients after autologous bone marrow transplantation for lymphoid or solid malignancies, resulting in increased production of granulocytes and platelets. G-CSF and GM-CSF have been used to treat aplastic anemia, myelodysplastic syndromes, chemotherapy-induced neutropenia, and neutropenia ...

Studies have shown that alcohol may contribute to neutropenia if you have an infection such as pneumonia. I never thought I would be diagnosed with the condition, even though I enjoy a nice glass of wine every now and then (I cant help it; I live in Napa where Im surrounded by vineyards.). The Diagnosis. Neutrophils are a type of white blood cells that can travel from your bloodstream and into the infected areas of your body, and is capable of destroying microorganisms. Last year, I decided to go to my doctor when I realized something was wrong with my body, and my doctor told me that most people who suffer from neutropenia can experience anything from:. • Ulcers. • Skin rashes. • Wounds that take a long time to heal. • Fever. • Severe abscesses. • Decrease in neutrophils. When my doctor informed me of these symptoms and what they meant, I was a bit worried. He mentioned that having high neutrophil counts can cause an autoimmune condition, such as Crohns disease and even ...

The compound 13-cis retinoic acid was first studied in the 1960s at Roche Laboratories in Switzerland by Werner Bollag as a treatment for skin cancer. Experiments completed in 1971 showed that the compound was likely to be ineffective for cancer and, surprisingly, that it could be useful to treat acne. However, they also showed that the compound was likely to cause birth defects, so in light of the events around thalidomide, Roche abandoned the product. In 1975, Gary Peck and Frank Yoder independently rediscovered the drug's use as a treatment of cystic acne while studying it as a treatment for lamellar ichthyosis, and published that work. Roche resumed work on the drug. In clinical trials, subjects were carefully screened to avoid including women who were or might become pregnant. Roche's New Drug Application for isotretinoin for the treatment of acne included data showing that the drug caused birth defects in rabbits. The FDA approved the application in 1982.
