TY - JOUR. T1 - Characterization of the PcCdc42 small G protein from Pneumocystis carinii, which interacts with the PcSte20 life cycle regulatory kinase. AU - Krajicek, Bryan J.. AU - Kottom, Theodore J.. AU - Villegas, Leah. AU - Limper, Andrew H.. PY - 2010. Y1 - 2010. N2 - Pneumocystis carinii (Pc) causes severe pneumonia in immunocompromised hosts. The binding of Pc trophic forms to alveolar epithelial cells is a central feature of infection, inducing the expression and activation of Pc-Ste20, a gene participating in mating, proliferation, and pseudohyphal growth. In related fungi, Ste20 proteins are generally activated by immediate upstream small G proteins of the Cdc42-like family. PcCdc42 has not been previously described in Pneumocystis. To address the potential role of such a G protein in Pneumocystis, PcCdc42 was cloned from a Pc cDNA library. Using the full-length 576-bp PcCdc42 cDNA sequence, a CHEF blot of genomic DNA yielded a single band, providing evidence that this gene is ...

To the Editor: Misra and colleagues (1) reported an increased incidence of anticardiolipin antibodies in patients with infectious mononucleosis and postulated the existence of cross-reactions between infectious (viral) antigens and cardiolipin. We report here our experience concerning immunologic and biochemical similarities between Pneumocystis carinii organisms and cardiolipin. We observed that in the acquired immunodeficiency syndrome (AIDS), anticardiolipin antibodies occurred almost exclusively among those patients who had active P. carinii pneumonia (2). To test the cross-reactive hypothesis, we did several experiments.. In the first set of experiments, rabbits were immunized with an antigen from P. carinii in Freunds adjuvant prepared according ...

The nonspecific histopathologic changes of diffuse alveolar damage (DAD) were the only findings in nine of 17 lung biopsy specimens containing Pneumocystis carinii infection. Because of the frequent absence of the classically described intra-alveolar frothy material, special stains for organisms should be performed on all biopsy specimens from immunocompromised patients that show DAD, and the diagnosis of Pneumocystis infection should not be discarded unless careful search for organisms using special stains is negative. ...

Glycosphingolipid (GSL) Lactosyl Ceramide (LacCer) is thought to be involved in Pneumocystis interaction with the host. Our previous results show that treatment with glycosphingolipid synthesis inhibitor PDMP reduces the fungus lung burden as well as symptoms of inflammation in mice with Pneumocystis pneumonia (PCP). Experiments were set up to resolve whether anti-inflammatory effects were due to the specific mechanisms involved in innate immune responses to Pneumocystis, or to some general anti-inflammatory property of PDMP. Animals were infected with live organisms, or challenged with either beta-glucan (the pro-inflammatory component of Pneumocystis cell wall) or LPS (inducer of lung inflammation unrelated to Pneumocystis). At the experimental endpoint the following inflammatory parameters were assessed: leukocyte recruitment to the lungs, production of pro-inflammatory cytokines and chemokines, histopathology and lung damage. Results show that glucan-induced acute inflammation partially ...

Summary Pneumocystis carinii pneumonia (PCP) is the most common opportunistic infection in children who have acquired immunodeficiency syndrome (AIDS). Despite the publication of guidelines for prophylaxis against PCP for children infected with human immunodeficiency virus (HIV) in 1991 (1), ongoing AIDS surveillance has detected no substantial decrease in PCP incidence among HIV-infected infants. Studies indicate that this continued incidence is associated with failure to identify HIV-infected children before PCP occurs and with limitations in the ability of CD4+ measurements to identify children at risk for PCP. In March 1994, the National Pediatric & Family HIV Resource Center, * in collaboration with CDC, convened a working group to review additional data about the occurrence of PCP among HIV-infected children and to reevaluate the 1991 PCP prophylaxis guidelines for children. This report summarizes these new data and presents revised PCP prevention guidelines that recommend a) promptly ...

Pneumocystis carinii pneumonia (PCP), the most common presenting manifestation of the acquired immunodeficiency syndrome (AIDS), is a major and recurring cause of morbidity and mortality for persons infected with the human immunodeficiency virus (HIV). In recent years, important advances have been made in understanding which patient subpopulations are athighest risk for developing PCP and in the design of chemotherapeutic regimens that can reduce the frequency of this illness. Recently, a number of experts* convened by the National Institutes of Health independently reviewed data on prophylaxis against PCP among persons infected with HIV, and then provided recommendations to the U.S. Public Health Service concerning which persons should receive prophylaxis and what specific prophylactic regimens should be used. The resulting guidelines are detailed below. BACKGROUND Since the early 1980s, management of PCP has become increasingly successful, and several effective chemotherapeutic regimens are ...

Pneumocystis pneumonia is a potentially life-endangering disease caused by the fungal pathogen Pneumocystis jiroveci. It is predominantly observed in immunocompromised individuals. This microorganism is the most common causative agent of opportunistic infections in patients who present with acquired immunodeficiency syndrome (AIDS) in developed countries.

Pneumocystis jiroveci (formerly known as P. carinii f.sp. hominis) is an opportunistic fungus that causes Pneumocystis pneumonia (PCP) in immunocompromised individuals. Pneumocystis jiroveci can be detected by polymerase chain reaction (PCR). To investigate the clinical importance of a positive Pneumocystis-PCR among HIV-uninfected patients suspected of bacterial pneumonia, a retrospective matched case-control study was conducted ...

Two hundred and eighty two specimens from 220 patients positive for HIV with respiratory tract symptoms, or febrile illness, or both, were examined for the presence of Pneumocystis carinii. Specimens were either induced sputum samples or bronchoalveolar lavage fluids. To establish the optimal method for laboratory diagnosis a comparison was made of detection of the organism by use of monoclonal antibody and immunofluorescence with conventional silver staining methods. Three commercially available reagents for immunofluorescence were also compared. Immunofluorescence was significantly more sensitive than the silver stain and the best results for immunofluorescence were obtained using. Northumbria Biologicals Ltd reagents.. ...

Os primeiros informes sobre este xénero fíxoos o brasileiro Carlos Chagas en 1909[12] que o descubriu en animais experimentais, pero confundiuno cun estadio do ciclo de vida de Trypanosoma cruzi (axente causal da enfermidae de Chagas) e posteriormente chamou a ambos os organismos Schizotrypanum cruzi, unha forma de tripanosoma que infectaba a humanos.[13] O redescubrimento de quistes de Pneumocystis fíxoo Antonio Carini en 1910 tamén no Brasil.[14] O xénero foi de novo descuberto en 1912 por Delanoë e Delanoë no Instituto Pasteur de París, que o atoparon en ratas e propuxeron para el o nome xenérico e específico de Pneumocystis carinii en honor a Antonio Carini.[15]. Pneumocystis foi redescrito como patóxeno humano en 1942 por dous investigadores holandeses, van der Meer e Brug, que o atoparon en tres novos casos humanos: un meniño de 3 meses cunha enfermidade cardíaca conxénita e en dúas autopsias (de entre 104 realizadas) dun neno e un adulto.[16] Como só había unha especie ...

The disease PCP is relatively rare in people with normal immune systems, but common among people with weakened immune systems, such as premature or severely malnourished children, the elderly, and especially persons living with HIV/AIDS (in whom it is most commonly observed).[1][10] PCP can also develop in patients who are taking immunosuppressive medications. It can occur in patients who have undergone solid organ transplantation or bone marrow transplantation and after surgery.[11] Infections with Pneumocystis pneumonia are also common in infants with hyper IgM syndrome, an X-linked or autosomal recessive trait. The causative organism of PCP is distributed worldwide[12] and Pneumocystis pneumonia has been described in all continents except Antarctica.[12] More than 75% of children are seropositive by the age of 4, which suggests a high background exposure to the organism. A post mortem study conducted in Chile of 96 persons who died of unrelated causes (suicide, traffic accidents, and so ...

Pneumocystis carinii fungal pneumonia with fungi filling the alveolar spaces of a human lung section. The pathogens are stained brown by the immunoperoxidase method. LM X26 - Stock Image C008/6040

Pneumocystis carinii pneumonia is a leading cause of morbidity and mortality in patients with the acquired immunodeficiency syndrome (AIDS). Much remains unknown about the basic biology of P. carinii and studies of this infection have been hampered by the lack of cultivation methods. We developed a sensitive and specific assay for P. carinii by utilizing DNA amplification of the P. carinii dihydrofolate reductase (DHFR) gene. By this method, P. carinii DNA was detected in the lungs of rats with experimentally induced P. carinii pneumonia 2 wk before the onset of histopathological changes. DNA amplification analysis of serum demonstrated that by 10 wk of corticosteroid treatment, 12 of 12 (100%) infected rats had circulating DHFR DNA. P. carinii DHFR DNA also was detected in the serum of patients with AIDS and active P. carinii pneumonia (12 of 14 sera collected prospectively). Patients with advanced AIDS but without a history of P. carinii pneumonia were negative by this assay (0 of 6 sera ...

SPN : Pneumocystis jiroveci is one of the major microbial pathogens associated with opportunistic pulmonary infections in patients receiving immunosuppressive therapy or with immune deficiencies. Presently, the most common means to diagnose Pneumocystis jiroveci infection is by microscopic detection of the organisms in specimens such as bronchoalveolar lavage, open lung biopsy tissue, induced sputum and transtracheal aspirate.

To the editor: Recently, Macher and coworkers (1) have described the usefulness of gram-staining touch preparations of lung biopsy material for the diagnosis of Pneumocystis carinii pneumonia in patients with the acquired immunodeficiency syndrome. This method is more rapid than the conventional staining techniques used to reveal the cystic form of this organism, and the sporozoites are easily visible within coagula seen in the touch preparations. Their report prompted us to use the Gram stain on freshly obtained (, 1 hour old) cellular phase material obtained by bronchoalveolar lavage from three patients with suspected P. carinii pneumonia (subsequently confirmed by ...

True polyploidy rarely occurs in humans, although polyploid cells occur in highly differentiated tissue, such as liver parenchyma, heart muscle, placenta and in bone marrow.[1][48] Aneuploidy is more common. Polyploidy occurs in humans in the form of triploidy, with 69 chromosomes (sometimes called 69, XXX), and tetraploidy with 92 chromosomes (sometimes called 92, XXXX). Triploidy, usually due to polyspermy, occurs in about 2-3% of all human pregnancies and ~15% of miscarriages.[citation needed] The vast majority of triploid conceptions end as a miscarriage; those that do survive to term typically die shortly after birth. In some cases, survival past birth may be extended if there is mixoploidy with both a diploid and a triploid cell population present. There has been one report of a child surviving to the age of seven months with complete triploidy syndrome. He failed to exhibit normal mental or physical neonatal development, and died from a Pneumocystis carinii infection, which indicates a ...

The development of a granulomatous histological reaction in PCP is unusual, occurring in only 3% of the cases of PCP identified in patients with malignancy at our institution. All of these patients had expected risk factors for development of PCP but they had atypical clinical features. The presentation was insidious with very minimal symptoms and the radiographs showed a reticulonodular pattern rather than the expected interstitial-alveolar infiltrates. This pattern is more characteristic of HIV infected patients than of those with malignancy where the presentation is often subacute to fulminant and dyspnoea is the prominent symptom.6 In addition, an increased serum level of LDH, which is a sensitive marker for the presence of PCP, was not found in our patients.7 The LDH level was normal or only slightly raised.. The unexpected finding of most clinical significance was the non-diagnostic bronchoscopy in all cases, even in the two cases from whom transbronchial biopsy specimens were taken in ...

N2 - Primaquine and other 8-aminoquinolines have been used to treat malaria, and more recently to treat P. cariiui infections, but the mechanism of action of this class of agents remains undefined. Our studies were designed to use primaquine as an affinity ligand to isolate putative targets for the drug in P. carinii. CNBractivated Sepharose was linked to primaquine under conditions that promoted reaction with the tree amino group of primaquine. A 40 kl) protein from extracts of P. carinii bound with high affinity to this resin and was eluted specifically by primaquine. The protein reacted with polvclonal antibodies specific for P. curinn prut.ins. No proteins were recovered if histidine or glycine was substituted for primaquine as the affinity ligand, or if extracts of uninfected rat lung were run on the primaquine ...

PCP is a rare disease in healthy people. However, it can be serious in those who have AIDS, cancer, or other conditions that weaken the immune system.. PCP is one of the most common pediatric illnesses associated with AIDS, especially in babies younger than 6 months old. Its prevention is very important in AIDS care since it is a leading cause of death in people with AIDS.. In kids who are already seriously ill, symptoms of this form of PCP begin suddenly with a fever, a cough, and difficulty breathing. A child may not cough up any mucus because it is usually too thick to come up with the cough. Other symptoms can include weight loss and night sweats.. Babies who are already sick or have a weakened immune system also can develop PCP. In most cases, the baby is 3 to 6 months old and has no fever, but gradually begins to breathe faster than normal. As the lung infection gets worse, breathing becomes more difficult, and the babys chest muscles may begin to retract (pull in abnormally) with each ...

Could the coronavirus be interfering with the immune system in a way that is allowing Pneumocystis pneumonia to thrive?. A: Yes. COVID has been linked to CD4+ (T helper) lymphopenia, possible via cytokine storm. The main risk factor for PCP is CD4+ lymphoooenia caused by HIV.. My understanding is that Pneumocystis pneumonia, otherwise known as PJP or PCP, is caused by a fungus. It is highly opportunistic, and is rarely seen in people with healthy immune systems. It is highly associated with AIDS/HIV. A: Its actually rarely seen with HIV these days (due to ART), useally in transplant or immunosupressed patients.. The fungus that causes it is widespread, and likely exists in the lungs of most healthy people.. I'm not sure about this one, but it seems relatively difficult to test for. Given it's rarity, it seems it is most are assumed to have it if they present symptoms and are positive for HIV/AIDS. If they are suspected, it seems they test for HIV/AIDS first.. A: It is easy to test for ...

In the study of infectious disease, access to the genome of a pathogen provides new information that can be pivotal in combating the diseases it causes. The hope is that the genome of P. jirovecii will lead to new advances in therapies for those suffering from Pneumocystis pneumonia. The current drugs of choice for treating Pneumocystis pneumonia are antifolates, but certain isolates of P. jirovecii have already developed resistance to antifolates, an ability that is very likely to spread.. Now that the genome of P. jirovecii is assembled and available to researchers all over the world, scientists can tease out clues about the organism that will help identify targets for some badly needed new drugs..

PNRP : Pneumocystis pneumonia is an important cause of opportunistic infection in immunocompromised patients, particularly those with HIV. The causative agent, Pneumocystis jiroveci, cannot be cultured in vitro and, therefore, laboratory detection has historically relied upon microscopic identification directly from patient specimens using fluorescent stains or antibodies. Unfortunately, stains often lack sensitivity and require expertise on the part of the reader in order to differentiate Pneumocystis jiroveci from staining artifacts and other fungi. This real-time PCR assay provides sensitive (21% more sensitive than direct detection using fluorescent calcofluor white stain), specific, and objective detection of Pneumocystis from bronchoalveolar lavage fluid and other specimens.

Pneumocystis jirovecii, previously known as Pneumocystis cariniii , is an opportunistic parasite that causes P. jirovecii pneumonia (PJP) in immunocompromised hosts. Most immunocompetent children acquire asymptomatic infection with P. jirovecii by the age of 4 years,1 while symptomatic disease occurs almost exclusively in severely immunocompromised hosts.. Pneumocystis has been recognised as a cause of pneumonia since the 1940s when epidemics of plasma cell pneumonia were diagnosed in malnourished and premature infants in care homes in Eastern Europe.2 In the 1960s, as immunosuppressive therapy for malignancy … ...

Background With the increasing use of immunosuppressive agents, the number of opportunistic infections has risen in patients with autoimmune diseases. Pneumocystis pneumonia (PCP) is one of these opportunistic infections that have a high mortality rate. However, only a few studies have described PCP in these patients, and these studies are limited in scope. We conducted this retrospective study to describe the clinical characteristics and factors associated with outcomes of PCP in patients with autoimmune diseases. Methods A retrospective study was performed in laboratory diagnosed PCP patients with autoimmune diseases in an academic hospital over a 10-year period. Patients with human immunodeficiency virus (HIV) infection were not included. Clinical characteristics were collected and the factors related to death were analysed. Results A total of 69 patients with PCP during the study period were included. Common clinical features included fever (81%), cough (56%), and dyspnea (35%). Ground glass

Background: Endogenous Neonatal Cushings syndrome (CS) is a rare condition with around 100 cases reported worldwide. Pneumocystis Jiroveci pneumonitis (PJP) is a well described, albeit rare, complication of exogenous CS (i.e. CS resulting from external glucocorticoids). The pneumonitis usually occurs following reduction of glucocorticoid dosage and is therefore thought to be triggered by an inappropriate immune reaction evident after glucocorticoids withdrawal, treatment of which includes both antibiotics and glucocorticoids. PJP has not been hitherto described in neonatal endogenous CS.. Objective: To describe the problems associated with therapy of life-threating PJP in a baby with active neonatal CS with particular attention to glucocorticoid levels.. Case presentation: A 3-month old female infant presented with failure of linear growth and mild hirsutism. She was diagnosed with CS, with high fasting cortisol levels (893 nmol/l). After low dose (15 mcg/kg) dexamethasone- cortisol ...

Our previous work demonstrated that ZDV plus SMX-TMP exposure significantly impairs developing B-lymphocyte populations in the bone marrow of mice (18). We have now shown that this toxicity alters the humoral immune response to an infectious challenge, although the overall clearance of the infection was not significantly affected. We have demonstrated that mice treated with ZDV plus SMX-TMP prior to Pneumocystis infection exhibit diminished B- and T-lymphocyte activation in the draining lymph nodes of the lungs. TBLN populations of CD19+ B cells, and CD4+ and CD8+ T cells were significantly reduced compared to those in the control mice on days 10 and 20 postinfection. B cells are responsible for differentiation into plasma cells that will secrete antibody against antigens associated with invading organisms; and as a result of the decreased cell numbers in the draining lymph nodes, Pneumocystis-specific serum IgG titers were significantly lower in the mice that were exposed to the combination of ...

Commercially available monoclonal antibodies to Pneumocystis carinii were compared with respect to immunofluorescence staining patterns of human immunodeficiency virus-inactivated smears. Only the indirect staining kits were suitable for application to ethanol-inactivated samples. When antibodies from Dakopatts and Northumbria were compared, the staining of cysts and trophozoites showed different patterns. ...

Immunocompromised individuals typically have at least one immune system component missing. They can either inherit or acquire these defects. For example, defects in a single gene can lead to two inherited immunodeficiency disorders that involve B cells. (See Defective Gene Linked to Two Inherited Immune Deficiencies.) These disorders predispose individuals to severe infections in the respiratory, sinus, and gastrointestinal systems. Many immunocompromised conditions, however, are acquired.. As for acquiring such defects, in 2006, UNAIDS and the World Health Organization estimated that approximately 39.5 milling people were living with HIV. That year alone, there were 4.3 million new infections, with the majority occurring in sub-Saharan Africa. HIV targets T cells, and in particular, T helper cells, which are critical to fighting infections caused by fungi and parasites. This is why people with advanced, untreated AIDS develop unusual infections such as Pneumocystis carinii pneumonia and ...

HIV Diagnosis. How did you find out you were HIV positive?. I found out in 1996. I found out when I was on my death bed in the hospital. What exactly were the circumstances? You became sick?. What had happened was that I was in a relationship for a while with my lover, my significant other, for about 10 years and he passed away from complications of AIDS, opportunistic infections. After he passed away, I was in denial for quite a long time, for at least three or four years. Then I got very sick, went to the hospital, ended up with PCP [pneumocystis carinii pneumonia] and thats where it all started. You didnt get tested until you were in the hospital?. Exactly. I kind of figured that I was positive, but I was going through the process of losing my partner and being more concerned about him than me ... being in denial and trying not to really take care of my own health and not paying attention. I waited until I was lying on my death bed in the hospital, and I still was in denial. I had ... ...

TY - JOUR. T1 - Epidemiology and clinical features of HIV infection/AIDS in Korea. AU - Kim, June Myung. AU - Cho, Goon Jae. AU - Hong, Sung Kwan. AU - Chang, Kyung Hee. AU - Chung, Joo Sup. AU - Choi, Young Hwa. AU - Song, Young Goo. AU - Huh, Aejung. AU - Yeom, Joon Sup. AU - Lee, Kkot Sil. AU - Choi, Jun Yong. PY - 2003/6/30. Y1 - 2003/6/30. N2 - HIV infection/AIDS shows characteristic epidemiological and clinical patterns according to the region, country, and race. The epidemiological and clinical patterns of HIV infection/AIDS in Korea was investigated by retrospectively analyzing the medical records of 176 HIV-infected persons who visited two major referral hospitals of AIDS in Korea from 1985 to April 2000. The most common transmission route was heterosexual contact (52.3%), followed by homosexual contact (23.9%). Among the opportunistic diseases, candidiasis was the most prevalent (21.6%), followed by Pneumocystis carinii pneumonia (15.9%), tuberculosis (12.5%), and CMV infection (9.1%). ...

BALTIMORE-Fludarabine (Fludara) and cyclophosphamide are highly active agents for indolent lymphomas, but when given in combination, opportunistic infections such as Pneumocystis carinii pneumonia (PCP) and herpes zoster may be dose limiting. 1

The potential benefits of methotrexate must be weighed against its side effects. Rash, nausea, diarrhoea, stomatitis, and other gastrointestinal symptoms necessitate its discontinuation in approximately 5% of patients. There are case reports of severe colitis complicating the use of methotrexate, although not yet in patients with Crohns disease.9 There is an increased risk of opportunistic infections, including herpes zoster and pneumocystis carinii pneumonia, but not of neoplasia other than lymphoproliferative disorders.10 The latter are related to previous infection with Epstein-Barr virus, and are sometimes reversible on methotrexate withdrawal. Because methotrexate is teratogenic, pregnancy or conception within six months of stopping treatment with methotrexate of either partner should be avoided. Breast feeding is also contraindicated.. Bone marrow depression occurs in up to 20% of patients with rheumatoid arthritis receiving low dose methotrexate but is usually reversible on stopping the ...

STUDY OBJECTIVES: To validate a previously developed multisystem organ failure (MSOF) score with and without the addition of the lactate dehydrogenase (LDH) level as a predictor of survival to hospital discharge in patients with AIDS-related Pneumocystis carinii pneumonia (PCP) and acute respiratory failure (ARF). DESIGN: Retrospective chart review between April 1, 1991, and September 30, 1996. SETTING: University-affiliated tertiary care center in downtown Vancouver, British Columbia, Canada.

By late 1980 and early 1981, it was starting to become apparent that something new and disturbing was happening. People were starting to fall ill with lethal forms of rare diseases, including pneumocystis pneumonia and a rare form of skin cancer called Kaposis sarcoma. The most visible of the first victims were gay men, though it would later become apparent that the syndrome was affecting other groups too. By April 1981, the US government had been alerted to what was going on by an upsurge in requests for Pentamidine, a rare drug used to treat pneumocystis. The syndrome was mentioned in the gay press in May 1981, and the following month it was reported in an article in a widely circulated weekly report published by the federal Centers for Disease Control, from where it found its way into the mainstream media. A task force was formed, and doctors strove to get on top of the problem. From the outset, it was suspected that a virus was to blame - indeed, doctors had already been worried about the ...
