A class of statistical methods applicable to a large set of probability distributions used to test for correlation, location, independence, etc. In most nonparametric statistical tests, the original scores or observations are replaced by another variable containing less information. An important class of nonparametric tests employs the ordinal properties of the data. Another class of tests uses information about whether an observation is above or below some fixed value such as the median, and a third class is based on the frequency of the occurrence of runs in the data.

An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.

Prolonged eosinophil accumulation in allergic lung interstitium of ICAM-2 deficient mice results in extended hyperresponsiveness. (1/3240)

ICAM-2-deficient mice exhibit prolonged accumulation of eosinophils in lung interstitium concomitant with a delayed increase in eosinophil numbers in the airway lumen during the development of allergic lung inflammation. The ICAM-2-dependent increased and prolonged accumulation of eosinophils in lung interstitium results in prolonged, heightened airway hyperresponsiveness. These findings reveal an essential role for ICAM-2 in the development of the inflammatory and respiratory components of allergic lung disease. This phenotype is caused by the lack of ICAM-2 expression on non-hematopoietic cells. ICAM-2 deficiency on endothelial cells causes reduced eosinophil transmigration in vitro. ICAM-2 is not essential for lymphocyte homing or the development of leukocytes, with the exception of megakaryocyte progenitors, which are significantly reduced.  (+info)

Effects of soybean oil emulsion and eicosapentaenoic acid on stress response and immune function after a severely stressful operation. (2/3240)

OBJECTIVE: To investigate the effects of soybean oil emulsion and oral or enteral administration of eicosapentaenoic acid (EPA) on stress response, cytokine production, protein metabolism, and immune function after surgery for esophageal cancer. SUMMARY BACKGROUND DATA: It has been reported that safflower oil, rich in n-6 polyunsaturated fatty acid (n-6 PUFA), affects the survival rate of septic animals and decreases the immune function. It has also been reported that the administration of fish oil, in contrast, reduces these stress responses and stress-induced immunosuppression. In humans, the effects of soybean oil emulsion and the administration of EPA on stress response and immune function after surgery have not been established. METHODS: Patients who underwent esophagectomy with thoracotomy were divided into three groups. Seven patients were fed by total parenteral nutrition (TPN) with soybean oil emulsion, which accounted for 20% of total calories. Seven patients were given oral or enteral administration of 1.8 g/day EPA, in addition to TPN with soybean oil emulsion. Nine patients served as the control group; these patients received fat-free TPN. Serum interleukin-6 (IL-6), C-reactive protein, concanavalin A (con A)- or phytohemagglutinin (PHA)-stimulated lymphocyte proliferation, natural killer cell activity, and stress hormones were measured. RESULTS: The postoperative level of serum IL-6 was significantly higher in the group receiving soybean oil emulsion than in the fat-free group. Oral or enteral supplementation of EPA with soybean oil emulsion significantly reduced the level of serum IL-6 compared with the patients receiving soybean oil emulsion. Con A- or PHA-stimulated lymphocyte proliferation decreased significantly on postoperative day 7 in all groups of patients. The supplementation of EPA with soybean oil emulsion significantly improved the lymphocyte proliferation and natural killer cell activity on postoperative day 21 compared with the group receiving soybean oil emulsion. CONCLUSIONS: Soybean oil emulsion amplifies, and the supplementation of EPA reduces, the stress response and stress-induced immunosuppression.  (+info)

N,N'-Diacetyl-L-cystine-the disulfide dimer of N-acetylcysteine-is a potent modulator of contact sensitivity/delayed type hypersensitivity reactions in rodents. (3/3240)

Oral N-acetyl-L-cysteine (NAC) is used clinically for treatment of chronic obstructive pulmonary disease. NAC is easily oxidized to its disulfide. We show here that N,N'-diacetyl-L-cystine (DiNAC) is a potent modulator of contact sensitivity (CS)/delayed type hypersensitivity (DTH) reactions in rodents. Oral treatment of BALB/c mice with 0.003 to 30 micromol/kg DiNAC leads to enhancement of a CS reaction to oxazolone; DiNAC is 100 to 1000 times more potent than NAC in this respect, indicating that it does not act as a prodrug of NAC. Structure-activity studies suggest that a stereochemically-defined disulfide element is needed for activity. The DiNAC-induced enhancement of the CS reaction is counteracted by simultaneous NAC-treatment; in contrast, the CS reaction is even more enhanced in animals treated with DiNAC together with the glutathione-depleting agent buthionine sulfoximine. These data suggest that DiNAC acts via redox processes. Immunohistochemically, ear specimens from oxazolone-sensitized and -challenged BALB/c mice treated with DiNAC display increased numbers of CD8(+) cells. DiNAC treatment augments the CS reaction also when fluorescein isothiocyanate is used as a sensitizer in BALB/c mice; this is a purported TH2 type of response. However, when dinitrofluorobenzene is used as a sensitizer, inducing a purported TH1 type of response, DiNAC treatment reduces the reaction. Treatment with DiNAC also reduces a DTH footpad-swelling reaction to methylated BSA. Collectively, these data indicate that DiNAC in vivo acts as a potent and effective immunomodulator that can either enhance or reduce the CS or DTH response depending on the experimental conditions.  (+info)

An epidemiological study on the association between the total leukocyte and neutrophil counts, and risk factors of ischemic heart disease by smoking status in Japanese factory workers. (4/3240)

Several epidemiologic studies have shown the association between total leukocyte count and the risk of developing myocardial infarction. The purpose of this study was to assess the association between the total leukocyte and neutrophil counts and risk factors of ischemic heart disease in 1,384 Japanese factory workers. Total leukocyte and neutrophil counts were significantly higher in current smokers than in non-smokers. Among current smokers, the total leukocyte and neutrophil counts were positively associated with the number of cigarettes smoked daily and the duration of cigarette smoking and alcohol consumption. Being independent of smoking habit, the total leukocyte and neutrophil counts were also related to several characteristics recorded at the physical examinations. The total leukocyte and neutrophil counts were positively associated with serum total cholesterol, serum triglyceride and hematocrit levels, and inversely associated with the serum HDL-cholesterol level. No significant associations of the total leukocyte or neutrophil counts were found with the red blood cell count and hemoglobin level. These results suggest that the total leukocyte and neutrophil counts may represent the metabolic condition with a high coronary risk among apparently healthy people.  (+info)

Immunodeficiency due to a unique protracted developmental delay in the B-cell lineage. (5/3240)

A unique immune deficiency in a 24-month-old male characterized by a transient but protracted developmental delay in the B-cell lineage is reported. Significant deficiencies in the number of B cells in the blood, the concentrations of immunoglobulins in the serum, and the titers of antibodies to T-dependent and T-independent antigens resolved spontaneously by the age of 39 months in a sequence that duplicated the normal development of the B-cell lineage: blood B cells followed by immunoglobulin M (IgM), IgG, IgA, and specific IgG antibodies to T-independent antigens (pneumococcal polysaccharides). Because of the sequence of recovery, the disorder could have been confused with other defects in humoral immunity, depending on when in the course of disease immunologic studies were conducted. Investigations of X-chromosome polymorphisms suggested that the disorder was not X linked in that the mother appeared to have identical X chromosomes. An autosomal recessive disorder involving a gene that controls B-cell development and maturation seems more likely. In summary, this case appears to be a novel protracted delay in the development of the B-cell lineage, possibly due to an autosomal recessive genetic defect.  (+info)

Predictive value of CD19 measurements for bacterial infections in children infected with human immunodeficiency virus. (6/3240)

We investigated the predictive value of CD19 cell percentages (CD19%) for times to bacterial infections, using data from six pediatric AIDS Clinical Trials Group protocols and adjusting for other potentially prognostic variables, such as CD4%, CD8%, immunoglobulin (IgA) level, lymphocyte count, prior infections, prior zidovudine treatment, and age. In addition, we explored the combined effects of CD19% and IgG level in predicting time to infection. We found that a low CD19% is associated with a nonsignificant 1.2-fold increase in hazard of bacterial infection (95% confidence interval: 0.97, 1.49). In contrast, a high IgG level is associated with a nonsignificant 0.87-fold decrease in hazard of infection (95% confidence interval: 0.68, 1.12). CD4% was more prognostic of time to bacterial infection than CD19% or IgG level. Low CD19% and high IgG levels together lead to a significant (P < 0. 01) 0.50-fold decrease in hazard (95% confidence interval: 0.35, 0. 73) relative to low CD19% and low IgG levels. Similarly, in a model involving assay result changes (from baseline to 6 months) as well as baseline values, the effect of CD19% by itself is reversed from its effect in conjunction with IgG. In this model, CD19% that are increasing and high are associated with decreases in hazard of infection (P < 0.01), while increasing CD19% and increasing IgG levels are associated with significant (at the P = 0.01 level) fourfold increases in hazard of infection relative to stable CD19% and decreasing, stable, or increasing IgG levels. Our data suggest that CD19%, in conjunction with IgG level, provides a useful prognostic tool for bacterial infections. It is highly likely that T-helper function impacts on B-cell function; thus, inclusion of CD4% in such analyses may greatly enhance the assessment of risk for bacterial infection.  (+info)

Dose-escalation study of docetaxel in combination with mitoxantrone as first-line treatment in patients with metastatic breast cancer. (7/3240)

PURPOSE: To define the maximum-tolerated dose (MTD) and the dose-limiting toxicities (DLTs) of docetaxel in combination with mitoxantrone in patients with metastatic breast cancer (MBC). PATIENTS AND METHODS: Forty-one chemotherapy-naive patients with MBC (median age, 61 years) were enrolled. Thirty-eight (93%) had performance status (World Health Organization [WHO]) 0, 29 (71%) were postmenopausal, and 21 (51%) had estrogen receptor-negative tumors. Patients received escalated doses of docetaxel (75 to 100 mg/m2) on day 1 and mitoxantrone (8 to 22 mg/m2) on day 8. Treatment was repeated every 3 weeks. RESULTS: A total of 217 chemotherapy cycles were administered. Without recombinant human granulocyte colony-stimulating factor (rhG-CSF) support, the MTD1 occurred at the first dose level (docetaxel 75 mg/m2 and mitoxantrone 8 mg/m2); DLTs were febrile neutropenia, grade 4 neutropenia lasting more than 5 days, and grade 3 diarrhea. With prophylactic rhG-CSF, the MTD2 was docetaxel 100 mg/m2 and mitoxantrone 20 mg/m2; DLTs were febrile neutropenia and grade 4 neutropenia. Nine (22%) patients developed neutropenia after the first cycle of treatment. A total of 19 episodes of febrile neutropenia (9% of the cycles) occurred during the whole period of the study; there were no toxic deaths. At high docetaxel (100 mg/m2) and mitoxantrone (> 12 mg/m2) dose levels, a significant decrease of the absolute lymphocyte number was observed; immunophenotyping revealed that all lymphocyte subpopulations were reduced. Grades 2 and 3 neurosensory toxicity occurred in six patients (15%) and one patient (2%), respectively. No cardiac toxicity was observed. Nine complete responses (22%) and 23 partial responses (56%) were achieved (overall response rate, 78%; 95% confidence interval, 62.5% to 88.8%). The median duration of response was 12.5 months, and the median time to tumor progression was 14.5 months. CONCLUSION: The reported combination of docetaxel and mitoxantrone with G-CSF support is a safe, intensified, well-tolerated, and effective regimen as first-line treatment in patients with MBC.  (+info)

Development of CD8+ effector T cells is differentially regulated by IL-18 and IL-12. (8/3240)

We investigated the effects of IL-18 on the development of CD8+ effector T cells in DBA/2 anti-BDF1 whole spleen cell MLC and compared the results with those of IL-12. Addition of IL-18 to the MLC resulted in a twofold increase in CD8/CD4 ratios compared with the control cultures when cells were expanded in IL-2-containing medium following MLC. Purified CD8+ T cells recovered from the IL-18-stimulated MLC produced 20- to 30-fold more IFN-gamma after secondary stimulation with C57BL/6 spleen cells or anti-CD3 mAb, and exhibited strong allospecific CTL activity. Neither IL-18 nor IL-18-supplemented culture supernatants from DBA/2 anti-BDF1 MLC induced type I CD8+ effector T cells when purified CD8+ T cells were used as responder cells in primary MLC. Furthermore, CD4+ T cell depletion from the responder cells abrogated the IL-18-induced increase in secondary IFN-gamma production by CD8+ T cells, suggesting that IL-18-induced type I effector CD8+ T cell development was CD4+ T cell dependent. In marked contrast, adding IL-12 to primary MLC decreased CD8/CD4 ratios by 50% and suppressed secondary IFN-gamma production and CTL activity by CD8+ T cells regardless of concentration, whereas Th1 development was promoted by IL-12. Moreover, both IL-12 and IL-18 efficiently induced type I CD8+ effector T cells in C57BL/6 anti-BDF1 MLC. These findings show that IL-18 plays an important role in the generation of type I CD8+ effector T cells, and further suggest that functional maturation of CD8+ T cells is differentially regulated by IL-18 and IL-12.  (+info)

HIVandHepatitis.com. CD4 cell count and CD4 cell percentage are key markers for determining disease progression and risk for opportunistic infection in HIV-infected patients.. These markers are of greatest use in treating the asymptomatic patient, in whom disease stage is more difficult to assess clinically and for whom laboratory measurements serve as guidelines for the initiation of therapy and opportunistic-infection prophylaxis.. However, providers in resource-constrained settings may not have access to this laboratory measurement or its cost may be prohibitive, resulting in the need for an alternative, surrogate marker. Given the decreasing costs and increased availability of antiretroviral therapy (ART) in the developing world, this is an issue of critical and increasing importance.. A number of previous studies indicate that the total lymphocyte count (TLC) may be useful as a surrogate marker of immune status in certain settings. However, controversy regarding the utility of the TLC ...

The patient is a 92-year-old woman who presented to the hematology clinic 3 years earlier for evaluation of persistent lymphocytosis. At that time, her white blood cell count was 15 200/µL, hemoglobin was 12.8 g/dL, and platelets were 245 000/µL. Her absolute lymphocyte count was 7870/µL. She did not have lymphadenopathy or hepatosplenomegaly on physical examination. Flow cytometry was performed and revealed a monoclonal B-cell proliferation that was CD5 and CD10 negative. Fluorescence in situ hybridization testing for t(11;14) and rearrangements/additions of chromosomes 11q, 12, 13q, and 17p13.1 were negative. The monoclonal lymphocytosis was monitored with serial surveillance. At the most recent clinic visit, her absolute lymphocyte count was 21 310/µL, and morphologic examination of the peripheral smear revealed mononuclear cells with Auer rod-like cytoplasmic inclusions. Flow cytometry redemonstrated the monoclonal B-cell proliferation, without any evidence of myeloid differentiation. A ...
Accurate monitoring of host immunity is hampered by the flaws of conventional tests. The relationship between lymphocyte number and function is unknown. The function of lymphocytes was analyzed based on IFN-γ secretion assay. Lymphocyte number and function was investigated in individuals under various states. The number of CD4+ and CD8+ T cells was gradually decreased, whereas the function of them was gradually increased with increasing age. A significantly negative correlation existed between the number and function of both CD4+ and CD8+ T cells. Differently, both the number and function of NK cells are maintained at a high level after birth. Staying up all night was found to impair the function of CD4+, CD8+ T cells, or NK cells. Lymphocyte number and function were both decreased in patients with immunosuppressive conditions or opportunistic infections, while the opposite phenomenon was observed in patients with some autoimmune

Background: In patients treated with dimethyl fumarate, absolute lymphocyte count decline typically occurs during the first year and then plateaus; early drops have been associated with the development of severe prolonged lymphopenia. Objective: We investigated the effect of dimethyl fumarate on absolute lymphocyte counts and CD4+/CD8+ T cells in patients with relapsing-remitting multiple sclerosis treated with dimethyl fumarate in routine practice. Methods: Lymphocyte data were collected via medical chart abstraction. Primary endpoint: change from baseline in absolute lymphocyte count and CD4+/CD8+ counts at 6-month intervals following dimethyl fumarate initiation. Results: Charts of 483 patients were abstracted and 476 patients included in the analysis. Mean baseline absolute lymphocyte count (2.23 × 10 Conclusion: Dimethyl fumarate-associated decline in absolute lymphocyte count in the first 12 months correlated with decline in CD4+ and CD8+ T cells and was independent of prior natalizumab.

To confirm the clinical diagnosis of ADA deficiency, it is first necessary to assess the patients immune function.. The workup should start with a complete blood cell (CBC) count with differential to determine absolute lymphocyte count, as well to assess lymphoid subpopulations/markers (i.e., percentages and absolute counts of CD3+ T cells, CD4+ T cells, CD8+ T cells, CD19+ B cells, and natural killer (NK) cell markers (CD16 and CD56)). In all ADA SCID patients, T cells, B cells, and NK cells are severely affected (T-B-NK- phenotype).. Lymphopenia with an absolute lymphocyte count of less than 2500 cells/mL in an infant definitely requires further testing. Any infant with severe or opportunistic infection should have the full diagnostic assessment. On average, SCID patients have less than 1500 lymphocytes/mL.. Total serum immunoglobulin (Ig) levels of IgG, IgA, IgM, and IgE should be obtained. All immunoglobulin classes are usually decreased, but not always.. Evaluation of lymphocyte function ...

N2 - Multiple reports have shown that low absolute lymphocyte count at day 30 (ALC30) after allogeneic hematopoietic SCT (AHSCT) is associated with higher risk of disease relapse and worse OS. However, these reports included heterogeneous populations with different grafts and GVHD prophylaxis. Therefore, we retrospectively evaluated the association of ALC30 with transplant outcomes in a cohort of 381 consecutive patients who underwent AHSCT between 2005 and 2010 and received T-replete PBSC grafts and Tacrolimus/Mycophenolate combination as GVHD prophylaxis. Median follow-up was 57 months. ...
Haematopoietic stem cells (HSCs), a very rare cell type in the bone marrow, are responsible for the life-long production of all cells of the blood including T and B cells. Until recently, it was thought that the differentiation of HSCs into the various haematopoietic cells was rather hierarchical in that differentiation along a given lineage was associated with a progressive loss of potential to give rise to other blood cell lineages. The recent development of very sensitive and quantitative in vitro assays, together with the identification of new progenitor subpopulations, has challenged this idea. Thus, lymphocyte progenitors can be shown to keep their developmental potential to give rise to myeloid, dendritic and NK cells until just prior to their final commitment stage. Here we review these new findings and concepts.
It is a week later and I still have a slight cough, but it is much, much better. With the excitement of the chest X-rays, I had forgotten to get my blood test results, so I got them today when I had my IVIg infusion. I knew they had been good lately, but I was shocked when I looked across the columns and saw that there has basically been NO CHANGE, neither in my white count nor in the absolute lymphocyte count since last March! After the rapid increases of late last year and early this year, the brakes were applied! Thank you, Lord. Even my platelets which had plummeted last month came back up to 120. My IgG level had only dropped into the 600s also. Still low enough for the infusion (under 700), but not real low.

It is a week later and I still have a slight cough, but it is much, much better. With the excitement of the chest X-rays, I had forgotten to get my blood test results, so I got them today when I had my IVIg infusion. I knew they had been good lately, but I was shocked when I looked across the columns and saw that there has basically been NO CHANGE, neither in my white count nor in the absolute lymphocyte count since last March! After the rapid increases of late last year and early this year, the brakes were applied! Thank you, Lord. Even my platelets which had plummeted last month came back up to 120. My IgG level had only dropped into the 600s also. Still low enough for the infusion (under 700), but not real low. The one thing I wish I had thought to ask and didnt was, why wasnt the white count way up last Monday when I was in the middle of the lung infection?

4. If the total lymphocyte count falls below 0.8 x 10**9/L, and is confirmed on a second FBC and the patient wants to stay on DMF it may be worth checking the JCV virus status. As DMF-related lymphopaenia is a form of immunosuppression** the JCV index, as measured using the STRATIFY JCV assay, cannot be used to assess PML risk. Please note a lymphocyte count cut-off of 0.8 x 10**9/L (WHO grade 2) may considered by some as being too conservative; but until data emerges to show that DMF-related lymphopaenia is reversible we feel this conservative approach is justified. ...
Replied on 04/19/2011 If you are inquiring whether there are other options for diagnosing or ruling out leukemia, it is very hard to tell with nothing but a price quote. This is something you should discuss with your veterinarian. If you are looking for options other than diagnostics for leukemia, there are certainly options. Your dog may indeed have a leukemic cancer, but as long as you have not noticed any symptoms of any problems, it may not be necessary to act on this high lymphocyte count. The important thing to ask yourself is this: Will you treat your dog or otherwise do anything differently if it turns out he has leukemia? If the answer is no, and it often is in a patient that is acting normally, then there may be no need to pursue leukemia diagnosis at this time. However, if learning with some certainty that your dog has leukemia would change your course of action, it may be wise for you to go ahead with the diagnostics. In the end, you are the only one who can make these important ...

5,000 CLL-type lymphocytes per mm³). If the diagnosis of CLL is based on the B cell count rather than the total lymphocyte count (which includes both B and T cells), many patients formerly diagnosed with Rai Stage 0 CLL would instead be classified as having MBL. Molecular techniques can detect monoclonal B cell levels as low as 3-5 B cells/microliter (comparable to the amount of stem cells in peripheral blood). The term monoclonal B-cell lymphocytosis was proposed by a consensus committee in 2005 to indicate a monoclonal B cell population in a person with fewer than 5,000 B lymphocytes per microliter (or 5.0 x 109 B lymphocytes/L), no enlarged lymph nodes or enlarged liver and/or spleen or other indications of a lymphoproliferative disorder. MBL has been found in less than 1% of asymptomatic adults under age 40, and in around 5% of adults older than 60. Exact numbers depend on the population studied and the sensitivity of the diagnostic technique. Like CLL, it appears to be more common in ...
Young women being underweight is a public health problem in Japan. The aim of this study was to investigate this problem by measuring lymphocyte count as an indicator of nutritional status. The subjects were 114 women aged 20-39 who participated in an annual health checkup for residents in a city in Aichi, Japan. Data from a questionnaire, physical examination, and blood tests were analyzed in relation to women who were severely underweight [body mass index (BMI) ≤ 17.5 kg/m2], slightly underweight (17.5 | BMI | 18.5 kg/m2), of normal weight (18.5 ≤ BMI | 25 kg/m2), and obese (BMI ≥ 25 kg/m2). Lymphocyte count tended to be lower with a decrease in BMI. The prevalence of low lymphocyte count of |1,500/mm3 increased in underweight women. In women who had restricted food intake for weight loss, leukocyte count, and total serum protein, and lymphocyte count were lower. A multivariate logistic regression analysis showed the association of low lymphocyte count to being severely underweight [odds ratio

Lymphocytes in peripheral blood (circulation) are heterogeneous and can be broadly classified into T cells, B cells, and natural killer (NK) cells. There are various subsets of each of these individual populations with specific cell-surface markers and function. This assay provides absolute (cells/mcL) and relative (%) quantitation for the main categories of T cells, B cells, and NK cells, in addition to a total lymphocyte count (CD45+). Each of these lymphocyte subpopulations have distinct effector and regulatory functions and are maintained in homeostasis under normal physiological conditions. Each of these lymphocyte subsets can be identified by a combination of one or more cell surface markers. The CD3 antigen is a pan-T cell marker, and T cells can be further divided into 2 broad categories, based on the expression of CD4 or CD8 coreceptors. B cells can be identified by expression of CD19, while NK cells are typically identified by the coexpression of CD16 and CD56.. The absolute counts of ...

Keep in mind that none of the symptoms listed are specific to CLL; these symptoms are also common to other illnesses.. During the visit with the doctor, you should describe all your symptoms. The doctor will ask detailed questions about medical history and perform a complete physical examination.. Signs are anything unusual that doctors or nurses notice when they examine their patients.. Frequently, a diagnosis is made when blood tests are performed as part of a routine annual check-up. An unexplained high lymphocyte count is the most common sign that leads a doctor to consider a CLL diagnosis. ...

In medicine neutrophil to lymphocyte ratio (NLR) is used as a marker of subclinical inflammation. It is calculated by dividing the number of neutrophils by number of lymphocytes, usually from peripheral blood sample, but sometimes also from cells that infiltrate tissue, such as tumor. Higher NLR is independent predictor of mortality in patients undergoing angiography or cardiac revascularization. Increased NLR is associated with poor prognosis of various cancers, such as esophageal cancer or pancreatic cancer. Wang X (Mar 2014).

Most patients with chronic lymphocytic leukemia (CLL) are diagnosed with early stage disease and managed with active surveillance. The individual course of subjects with early stage CLL is heterogeneous and their probability of needing treatment is hardly anticipated at diagnosis. We aimed at developing an international prognostic score to predict time to first treatment (TTFT) in CLL patients with early, asymptomatic disease (IPS-E). Individual patient data from 11 international cohorts of patients with early stage CLL (n=4933) were analyzed to build and validate the prognostic score. Three covariates were consistently and independently correlated with TTFT: unmutated IGHV genes, absolute lymphocyte count ,15 x109/l, and presence of palpable lymph nodes. The IPS-E was the sum of the covariates (one point each), and separated low-risk (score 0), intermediate-risk (score 1) and high-risk patients (score 2-3) showing a distinct TTFT. The score accuracy was validated in 9 cohorts staged by the ...
partial, second, or subsequent response or remained stable to at least 2 prior treatments. Median overall (OS) and progression-free (PFS) survivals were 9 and 6.3 years, respectively. The estimated 4-year OS and PFS were found to be 75% and 69%, respectively. In univariate analysis liver involvement, clinical stage at diagnosis, lymphocyte/monocyte count, and status of clinical response at ASCT were found to influence OS, however only absolute lymphocyte count remained significant in multivariate analysis (HR 1.42 [95% CI: 1.08-1.87]; p = 0.01). Median follow-up from ASCT to the last contact was 4.4 years (range 0.03-18.7). In total, 26 patients died from disease progression and subsequent resistance to chemotherapy. At the last contact, 27 patients were alive in remission. Only a single patient died shortly after ASCT due to infectious complications. Grade 3 or 4 non-hematological side effects were not observed in the remaining patients. ASCT for RR DLBCL is a safe procedure with a high ...

Malawi offers antiretroviral treatment (ART) to all HIV-positive adults who are clinically classified as being in WHO clinical stage III or IV without universal CD4 testing. This study was conducted among such adults attending a rural district hospital HIV/AIDS clinic (a) to determine the proportion who have CD4 counts ,or=350 cells/microl, (b) to identify risk factors associated with such CD4 counts and (c) to assess the validity and predictive values of possible clinical markers for CD4 counts ,or=350 cells/microl. A CD4 count ,or=350 cells/microl was found in 36 (9%) of 401 individuals who are thus at risk of being placed prematurely on ART. A body mass index (BMI) ,22 kg/m(2), the absence of an active WHO indicator disease at the time of presentation for ART, and a total lymphocyte count ,1,200 cells/microl were significantly associated with such a CD4 count. The first two of these variables could serve as clinical markers for selecting subgroups of patients who should undergo CD4 testing. ...

It has been awhile since I updated this blog … and for good reason - there hasnt been anything to say. Two years ago, April 10th, I had my last chemo treatment. File that under WOW, Time flies!! Today, I had my quarterly blood-letting to check to see how things are going. In some respects, those two years have passed like I only blinked my eyes, but in others, I realize how much I have accomplished and how my life has changed … for the better. Throughout it all, my doctor has been thrilled with my blood values, as they have been smack dab in the middle of the normal range. That changed today.. Today my visit brought a bit of news. My lymphocyte count is no longer in the normal range; it has crossed the line into the high territory. At this juncture, the doctor is adopting a wait and see attitude because I have recently been sick, and that could be the cause of the elevated lymphocyte count. We discussed testing, but since the tests she would run at this time were negative when my system ...
You state in your message that you are concerned about the risk of PML with all other non injectable therapies, but it is not clear to me why you have this concern with most of these therapies. The risk of PML is extremely low with all DMTs except Tysabri or long term immunosuppression with drugs we rarely use anymore. There have been no cases reported with Aubagio, rare cases with Gilenya and only a handful of cases on Tecfidera, usually in people who continued on treatment despite persistent lowering of their blood lymphocyte count. Similarly, we have seen no cases with Lemtrada or Ocrevus treatment and expect the risk to be low with these treatments ...

Neutrophils are normally found in the bloodstream and are the most abundant type of phagocyte, constituting 60% to 65% of the total circulating white blood cells.[4] One litre of human blood contains about five billion (5x109) neutrophils,[5] which are about 12-15 micrometers in diameter.[6] Once neutrophils have received the appropriate signals, it takes them about thirty minutes to leave the blood and reach the site of an infection.[7] Neutrophils do not return to the blood; they turn into pus cells and die.[7] Mature neutrophils are smaller than monocytes, and have a segmented nucleus with several sections(two to five segments); each section is connected by chromatin filaments. Neutrophils do not normally exit the bone marrow until maturity, but during an infection neutrophil precursors called myelocytes and promyelocytes are released.[8]. Neutrophils have three strategies for directly attacking micro-organisms: phagocytosis (ingestion), release of soluble anti-microbials (including granule ...
