In-vivo therapeutic efficacy in experimental murine mycoses of a new formulation of deoxycholate-amphotericin B obtained by mild heating. (1/1120)

Heat-induced 'superaggregation' of deoxycholate-amphotericin B (AmB-DOC, Fungizone) was shown previously to reduce the in-vitro toxicity of this antifungal agent. We compared AmB-DOC with the formulation obtained by heating the commercial form (Fungizone, Bristol Myers Squibb, Paris, France) for 20 min at 70 degrees C, in the treatment of murine infections. An improvement of antifungal activity was obtained with heated AmB-DOC formulations due to a lower toxicity which allowed the administration of higher drug doses than those achievable with the commercial preparation. Single intravenous injections of heated AmB-DOC solutions were demonstrated to be two-fold less toxic than unheated ones to healthy mice. For mice infected with Candida albicans, the maximum tolerated dose was higher with heated than with unheated AmB-DOC solutions. In the model of murine candidiasis, following a single dose of heated AmB-DOC 0.5 mg/kg, 85% of mice survived for 3 weeks, whereas at this dose the immediate toxicity of the standard formulation in infected mice restricted the therapeutic efficacy to 25% survival. Both formulations were equally effective in increasing the survival time for murine cryptococcal pneumonia and meningoencephalitis. Injection of heated AmB-DOC solutions at a dose two-fold higher than the maximal tolerated dose observed with the unheated preparation (1.2 mg/kg) increased the survival time by a factor of 1.4 in cryptococcal meningoencephalitis. These results indicate that mild heat treatment of AmB-DOC solutions could provide a simple and economical method to improve the therapeutic index of this antifungal agent by reducing its toxicity on mammalian cells.  (+info)

A comparison of itraconazole versus fluconazole as maintenance therapy for AIDS-associated cryptococcal meningitis. National Institute of Allergy and Infectious Diseases Mycoses Study Group. (2/1120)

This study was designed to compare the effectiveness of fluconazole vs. itraconazole as maintenance therapy for AIDS-associated cryptococcal meningitis. HIV-infected patients who had been successfully treated (achieved negative culture of CSF) for a first episode of cryptococcal meningitis were randomized to receive fluconazole or itraconazole, both at 200 mg/d, for 12 months. The study was stopped prematurely on the recommendation of an independent Data Safety and Monitoring Board. At the time, 13 (23%) of 57 itraconazole recipients had experienced culture-positive relapse, compared with 2 relapses (4%) noted among 51 fluconazole recipients (P = .006). The factor best associated with relapse was the patient having not received flucytosine during the initial 2 weeks of primary treatment for cryptococcal disease (relative risk = 5.88; 95% confidence interval, 1.27-27.14; P = .04). Fluconazole remains the treatment of choice for maintenance therapy for AIDS-associated cryptococcal disease. Flucytosine may contribute to the prevention of relapse if used during the first 2 weeks of primary therapy.  (+info)

Cryptococcosis in children with AIDS. (3/1120)

We compiled the clinical and immunologic features of Cryptococcus neoformans infections in human immunodeficiency virus (HIV)-infected children from 1985 to 1996 in a retrospective case series. Thirty cases of cryptococcosis were identified. These children had a median age of 9.8 years, a median CD4+ cell count of 54/microL at the time of diagnosis, and either a culture positive for C. neoformans or cryptococcal antigen in serum or cerebrospinal fluid. Sixty-three percent of the cases occurred in children vertically infected with HIV and in children between 6 and 12 years of age. The clinical and laboratory characteristics of this pediatric cohort were similar to those of adults with AIDS and cryptococcosis. On the basis of a subset of the cases, a 10-year point prevalence of cryptococcosis among children with AIDS of approximately 1% was estimated.  (+info)

Variants of a Cryptococcus neoformans strain elicit different inflammatory responses in mice. (4/1120)

Heat shock protein 70 (hsp70) as a major target of the antibody response in patients with pulmonary cryptococcosis. (6/1120)

Cryptococcus neoformans causes infection in individuals with defective T cell function, such as AIDS, as well as without underlying disease. It has been suggested that humoral as well as cellular immunity might play an important role in the immune response to C. neoformans infection. We have recently shown, using immunoblotting, that the 70-kD hsp family of C. neoformans was the major target molecule of the humoral response in murine pulmonary cryptococcosis. In this study we also used immunoblotting to define the antibody responses in the sera of 24 patients with pulmonary cryptococcosis: 21 proven and three suspected diagnoses. Anti-C. neoformans hsp70 antibody was detected in 16 of 24 (66.7%) patients with pulmonary cryptococcosis. Fourteen of 17 (82.3%) patients with high antigen titres (> or = 1:8) and two of seven (28.6%) patients with low titres (< or = 1:4) had detectable levels of anti-hsp70 antibody. Sera from patients positive for anti-hsp70 antibody showed high titres in the Eiken latex agglutination test for the detection of serum cryptococcal antigen. Our results indicate that the 70-kD hsp family from C. neoformans appears to be a major target molecule of the humoral response, not only in murine pulmonary cryptococcosis, but also in human patients with pulmonary cryptococcosis.  (+info)

Role of the C-C chemokine, TCA3, in the protective anticryptococcal cell-mediated immune response. (7/1120)

Activated T lymphocytes play a crucial role in orchestrating cellular infiltration during a cell-mediated immune (CMI) reaction. TCA3, a C-C chemokine, is produced by Ag-activated T cells and is chemotactic for neutrophils and macrophages, two cell types in a murine CMI reaction. Using a gelatin sponge model for delayed-type hypersensitivity (DTH), we show that TCA3 is a component of the expression phase of an anticryptococcal CMI response in mice. TCA3 mRNA levels are augmented in anticryptococcal DTH reactions at the same time peak influxes of neutrophils and lymphocytes are observed. Neutralization of TCA3 in immunized mice results in reduced numbers of neutrophils and lymphocytes at DTH reaction sites. However, when rTCA3 is injected into sponges in naive mice, only neutrophils are attracted into the sponges, indicating TCA3 is chemotactic for neutrophils, but not lymphocytes. We show that TCA3 is indirectly attracting lymphocytes into DTH-reactive sponges by affecting at least one other chemokine that is chemotactic for lymphocytes. Of the two lymphocyte-attracting chemokines assessed, monocyte-chemotactic protein-1 and macrophage-inflammatory protein-1alpha (MIP-1alpha), only MIP-1alpha was reduced when TCA3 was neutralized, indicating that TCA3 affects the levels of MIP-1alpha, which attracts lymphocytes into the sponges. TCA3 also plays a role in protection against Cryptococcus neoformans in the lungs and brains of infected mice, as evidenced by the fact that neutralization of TCA3 results in increased C. neoformans CFU in those two organs.  (+info)

Antibody response to Cryptococcus neoformans proteins in rodents and humans. (8/1120)

The prevalence and specificity of serum antibodies to Cryptococcus neoformans proteins was studied in mice and rats with experimental infection, in individuals with or without a history of potential laboratory exposure to C. neoformans, human immunodeficiency virus (HIV)-positive individuals who developed cryptococcosis, in matched samples from HIV-positive individuals who did not develop cryptococcosis, and in HIV-negative individuals. Rodents had little or no serum antibody reactive with C. neoformans proteins prior to infection. The intensity and specificity of the rodent antibody response were dependent on the species, the mouse strain, and the viability of the inoculum. All humans had serum antibodies reactive with C. neoformans proteins regardless of the potential exposure, the HIV infection status, or the subsequent development of cryptococcosis. Our results indicate (i) a high prevalence of antibodies reactive with C. neoformans proteins in the sera of rodents after cryptococcal infection and in humans with or without HIV infection; (ii) qualitative and quantitative differences in the antibody profiles of HIV-positive individuals; and (iii) similarities and differences between humans, mice, and rats with respect to the specificity of the antibodies reactive with C. neoformans proteins. The results are consistent with the view that C. neoformans infections are common in human populations, and the results have implications for the development of vaccination strategies against cryptococcosis.  (+info)

Cryptococcus neoformans, the causative fungal agent of cryptococcosis remain a common cause of infectious morbidity and mortality, especially among HIV-positive patients living in Sub-Saharan Africa and South-East Asia. This study was undertaken to evaluate the prevalence and clinical presentation of Cryptococcus infections among HIV positive and negative patients in RIMS, Manipur. Specimens like CSF, sputum, urine, blood, tissue biopsy or aspirates from clinically suspected cryptococcosis cases from RIMS hospital, were subjected to mycological examination. Out of the 48 patients enrolled for the study, Cryptococcus spp were isolated from 16 (33.33%) patients. Among these 16 cryptococcosis patients, majority of them presented with cryptococcal meningitis 13 (81.25%), while 1 (6.25%) patient each presented with cryptococcal lymphadenitis, disseminated cutaneous cryptococcosis and osseous cryptococcosis respectively. Also, of these 16 cryptococcosis patients, 14 (87.5%) were HIV positive. Among these HIV
Cryptococcosis, also known as cryptococcal disease, is a potentially fatal fungal disease. It is caused by one of two species; Cryptococcus neoformans and Cryptococcus gattii. These were all previously thought to be subspecies of C. neoformans but have now been identified as distinct species. Cryptococcosis is believed to be acquired by inhalation of the infectious propagule from the environment. Although the exact nature of the infectious propagule is unknown, the leading hypothesis is the basidiospore created through sexual or asexual reproduction. Cryptococcosis is a defining opportunistic infection for AIDS, and is the second-most-common AIDS-defining illness in Africa. Other conditions that pose an increased risk include certain lymphomas (e.g., Hodgkins lymphoma), sarcoidosis, liver cirrhosis, and patients on long-term corticosteroid therapy. Distribution is worldwide in soil. The prevalence of cryptococcosis has been increasing over the past 20 years for many reasons, including the ...

Background Cryptococcus neoformans causes life-threatening meningitis. A recently introduced lateral flow immunoassay (LFA) to detect cryptococcal antigen (CRAG) is reportedly more rapid and convenient than standard latex agglutination (LA), but has not yet been evaluated in a diagnostic laboratory setting. Methods One hundred and six serum, 42 cerebrospinal fluid (CSF), and 20 urine samples from 92 patients with known or suspected cryptococcosis were tested by LA and LFA, and titres were compared. Results were correlated with laboratory-confirmed cryptococcosis. Serial samples were tested in nine treated patients. Results Twenty-five of 92 patients had confirmed cryptococcosis; all sera (n = 56) from these patients were positive by LFA (sensitivity 100%, 95% confidence interval (CI) 93.6-100%) compared with 51/56 positive by LA (sensitivity 91.1%, 95% CI 80.7-96.1%). Fifty sera from 67 patients without cryptococcosis tested negative in both assays. While LA yielded more false negative results (5/56

Cryptococcosis is a fungal infection caused specifically by the fungus cryptococcus neofromans, which is usually found in soil and bird droppings or less commonly, the fungus cryptococcus gatti, found in sub-tropical regions. An individual usually contracts this infection through the air by breathing in the spores. Cryptococcocsis is most commonly associated with HIV and with people with weakened immune systems such as Hodgkins disease, individuals taking high doses of corticosteroid medications or undergoing chemotherapy. However, cryptococcocsis may affect individuals with normal immune systems as well. In some cases, there are no symptoms at all, however because the fungus is typically inhaled, the lungs are most commonly infected. It is more likely to spread beyond the lungs to the brain (and cause meningitis) in individuals with weakened immune systems. Symptoms may include blurred vision, chest pain, fatigue, dry coughs, fever, headache, nausea, sweating, and skin rashes. Other symptoms ...

Jones FX Fracture line extends to 4-5 intermetatarsal space. Cryptococcosis is the most common fungal disease in HIV -infected persons, and it is the AIDS-defining illness for 60-70% of HIV-infected patients.. In addition to invading the lung and CNS, cryptococci also invade the skin, bone, and genitourinary tract, but meninges appear to be the preferred site.. Cryptococcal disease usually develops only when CD4+ lymphocyte counts fall below 100 cells/microL.. Disease onset is usually insidious; time from symptom onset to diagnosis is, on average, 30 days or more. The delay also may be due to the waxing-and-waning course and the nonspecificity of symptoms.

The terms above describe general types of diseases because they dont provide specific information about the cause of the disease process. Once the cause has been determined, the name may change. For example, the veterinarian may determine that a patient has inflammation of the meninges (i.e. meningitis). Once it has been determined that the meningitis is caused by an infection from the fungus, coccidiomycosis, the name will change to Cocci meningitis and the patient can be specifically treated for this disease process. Also, the suffix -us denotes an organism and -osis denotes a condition. Therefore, Cryptococcosis is an infection caused by the fungus Cryptococcus.. If multiple areas are being affected by a process, two or more prefixes can be combined. For example ...
The researchers analyzed clinical cultures collected during a prospective study on cryptococcosis. Using molecular analysis of unpurified isolates they uncovered an unexpectedly high frequency (almost 20 percent) of mixed infections. They further demonstrated that these mixed infections could result from infestation by multiple strains acquired from the environment and that the strains were also evolving during infection.. The concept of one strain/one infection does not hold true for C neoformans and may apply to other environmentally acquired fungal pathogens. The possibility of mixed and/or evolving infections should be taken into account when developing therapeutic strategies against these pathogens, says Dromer.. mBio™ is a new open access online journal published by the American Society for Microbiology to make microbiology research broadly accessible.

The primary study outcome was the death rate 24 weeks after starting treatment. Intent to treat analysis which counted everyone randomised showed that enhanced prophylaxis was associated with a significantly reduced risk of death. 8.9% of those in the enhanced prophylaxis arm died compared to 12.2% of those in the standard of care arm, a risk reduction of 27% (HR 0.73, 95% CI 0.54-0.97, p = 0.03) and this difference was sustained at week 48 (HR 0.75, 95% CI 0. 58-0.98, p = 0.04).. Analysis of the primary causes of death showed that death due to Cryptococcus was significantly reduced in the enhanced prophylaxis arm (p = 0.03) but there was no difference in rates of death due to TB or bacterial infections. The investigators concluded that, in most cases, the causes of death were multifactorial. Nevertheless, the study found that enhanced prophylaxis was associated with a reduction in new cases of TB, cryptococcal disease or candida, but not of bacterial infections.

TY - JOUR. T1 - Monoclonal antibodies can affect complement deposition on the capsule of the pathogenic fungus Cryptococcus neoformans by both classical pathway activation and steric hindrance. AU - Zaragoza, Oscar. AU - Casadevall, Arturo. N1 - Copyright: Copyright 2008 Elsevier B.V., All rights reserved.. PY - 2006/12. Y1 - 2006/12. N2 - The capsule of the human pathogenic fungus Cryptococcus neoformans presents the immune system with a formidable problem for phagocytosis. Capsule-mediated activation of the alternative complement (C) pathway results in component 3 (particularly, C3) binding to the capsule near the cell wall surface. Hence, for cells with large capsule, C3 cannot interact with the complement receptor (CR) and is not opsonic. However, C activation in either immune serum or in the presence of monoclonal antibody (mAb) to capsular polysaccharide localizes C3 to the capsular edge. When C.neoformans cells were coated with both C and antibody (Ab) opsonins, Ab bound first and ...
The lysis of infected cells by disease-causing microorganisms is an efficient but risky strategy for disseminated infection, as it exposes the pathogen to the full repertoire of the hosts immune system. Cryptococcus neoformans is a widespread fungal pathogen that causes a fatal meningitis in HIV and other immunocompromised patients. Following intracellular growth, cryptococci are able to escape their host cells by a non-lytic expulsive mechanism that may contribute to the invasion of the central nervous system. Non-lytic escape is also exhibited by some bacterial pathogens and is likely to facilitate long-term avoidance of the host immune system during latency. Here we show that phagosomes containing intracellular cryptococci undergo repeated cycles of actin polymerisation. These actin flashes occur in both murine and human macrophages and are dependent on classical WASP-Arp2/3 complex mediated actin filament nucleation. Three dimensional confocal imaging time lapse revealed that such flashes ...
Unique clinical characteristics and other variables influencing the outcome of Cryptococcus neoformans infection in organ transplant recipients have not been well defined. From a review of published reports, we found that C. neoformans infection was documented in 2.8% of organ transplant recipients (overall death rate 42%). The type of primary immunosuppressive agent used in transplantation influenced the predominant clinical manifestation of cryptococcosis. Patients receiving tacrolimus were significantly less likely to have central nervous system involvement (78% versus 11%, p =0.001) and more likely to have skin, soft-tissue, and osteoarticular involvement (66% versus 21%, p = 0.006) than patients receiving nontacrolimus-based immunosuppression. Renal failure at admission was the only independently significant predictor of death in these patients (odds ratio 16.4, 95% CI 1.9 - 143, p = 0.004). Hypotheses based on these data may elucidate the pathogenesis and may ultimately guide the management of C.

We previously observed that administration of a monoclonal antibody (MAb) to the capsular polysaccharide to mice with pulmonary infection prolonged survival and enhanced granulomatous inflammation without reducing lung CFU. To understand the mechanism of MAb action, we studied leukocyte recruitment and cytokine profiles in lungs of A/JCr mice. B lymphocytes were the predominant cell type in lung infiltrates, comprising 15 to 30% of the leukocytes. Despite alterations in histological appearance, fluorescence-activated cell sorter analysis revealed no significant difference in total numbers of lung ...

Cryptococcosis, predominantly meningoencephalitis, emerged with the HIV pandemic, primarily afflicting HIV-infected patients with profound T-cell deficiency. Where in use, combination antiretroviral therapy has markedly reduced the incidence of and risk for disease, but cryptococcosis continues to afflict those without access to therapy, particularly in sub-Saharan Africa and Asia. However, cryptococcosis also occurs in solid organ transplant recipients and patients with other immunodeficiencies as well as those with no known immunodeficiency. This article reviews innate and adaptive immune responses to C. neoformans, with an emphasis on recent studies on the role of B cells, natural IgM and Fc gamma receptor polymorphisms in resistance to cryptococcosis..

Innate immunity plays an important role for fungal recognition and initiation of fungicidal activity. We hypothesize that subtle differences in different molecules of innate immunity may contribute to either the predisposition or clinical course of infection with Cryptococcus neoformans. To test this hypothesis, we propose to analyze the allelic frequencies of 15 different genes (mannose binding lectin, Fc-gamma receptor IIa and IIb, Fc-gamma receptors IIIa and IIIb, myeloperoxidase, tumor necrosis factor-alpha and -beta, interleukin 1A and 1B, interleukin-1 receptor antagonist, interleukin-10, NRAMP-1, chitotriosidase, and chemokine receptor 5) and their intragenic polymorphic forms and to compare this data to the incidence and severity of C neoformans infection. With this study we hope to identify a group of molecules of innate immunity which influence the risk and severity of invasive C neoformans infection ...

To test this hypothesis, we propose to analyze the allelic frequencies of 15 different genes (mannose binding lectin, Fc-gamma receptor IIa and IIb, Fc-gamma receptors IIIa and IIIb, myeloperoxidase, tumor necrosis factor-alpha and -beta, interleukin 1A and 1B, interleukin-1 receptor antagonist, interleukin-10, NRAMP-1, chitotriosidase, and chemokine receptor 5) and their intragenic polymorphic forms and to compare this data to the incidence and severity of C neoformans infection. With this study we hope to identify a group of molecules of innate immunity which influence the risk and severity of invasive C neoformans infection ...
Diagnosis of invasive cryptococcal infection in apparently nonimmunocompromised patients is difficult and often delayed. Human immunodeficiency virus- (HIV-) negative patients with decompensated hepatic cirrhosis might be at high risk of cryptococcal infection. We report here an 82-year-old Japanese female with end-stage hepatic failure and undergoing renal dialysis, hospitalized with septic shock-like symptoms. The patient had had hepatitis B virus (HBV) infection in the past. She survived only 4 days following admission. During hospitalization, she was found to have pleural effusion and ascites.|i| Cryptococcus neoformans|/i| was obtained from blood culture but not from pleural effusion culture. Consequently, the patient was diagnosed as having invasive cryptococcosis in association with HBV-related hepatic cirrhosis. Unfortunately, the patient died prior to receiving antifungal agents. Twelve Japanese cases of hepatic cirrhosis-related invasive cryptococcal infection, consisting of previously
A polysaccharide capsule is one of the most important virulence factors for the pathogenic fungus Cryptococcus neoformans. We previously characterized two capsule-associated genes,CAP59 and CAP64. To further dissect the molecular mechanism of capsule synthesis, 16 acapsular mutants induced by 4-nitroquinoline-1-oxide were obtained. The acapsular phenotype of one of these mutants was complemented. The cloned gene was designatedCAP60, and deletion of this newly described capsule-associated gene resulted in an acapsular phenotype. The proposed 67-kDa Cap60p contains 592 amino acids and appears to have a putative transmembrane domain close to the N terminus. DNA sequence analysis revealed that CAP60 has similarity toCAP59 at the center portion of its coding regions. Contour-clamped homogeneous electric field blot analysis suggested that these two genes are on the same chromosome. CAP60 andCAP59, however, could not be functionally substituted for each other by direct complementation or by domain swap ...
The main principles for the genetic pathophysiology of cryptococcosis will probably be consistent among all three varieties. In this chapter the author considers the yeasts to be different varieties or serotypes. Seven major areas are examined to support the potential molecular insights into this pathogenic yeast which will allow one to identify drug targets, define drug resistance mechanisms, and/or prepare mutants or fungal products for protective fungal vaccines. Initial molecular biology studies focused on distinguishing molecular strain differences with the use of karyotypes, repetitive elements, and eventually randomly amplified polymorphic DNAs, amplification fragment length polymorphisms, and PCR fingerprinting for strain genotyping. Cryptococcus neoformans has several well-characterized virulence phenotypes which have been approached in their understanding by both genetic and molecular tools. Experimental cryptococcosis in animal models has tended to be associated with large inocula or some
Cryptococcal infection is acquired from the environment. C. neoformans and C. gattii inhabit different ecologic niches. C. neoformans is frequently found in soils contaminated with avian excreta and can easily be recovered from shaded and humid soils contaminated with pigeon droppings. In contrast, C. gattii is not found in bird feces. Instead, it inhabits a variety of arboreal species, including several types of eucalyptus tree. C. neoformans strains are found throughout the world; however, var. grubii (serotype A) strains are far more common than var. neoformans (serotype D) strains among both clinical and environmental isolates. The geographic distribution of C. gattii was thought to be largely limited to tropical regions until an outbreak of cryptococcosis caused by a new serotype B strain began in Vancouver in 1999. This outbreak has extended into the United States, and C. gattii infections are being encountered increasingly in several states in the Pacific Northwest. ...
In Japan, most cases of cryptococcosis are caused by Cryptococcus neoformans(C. neoformans). Until now, only three cases which the infectious agent was Cryptococcus neoformans var. gattii(C. gattii)have been reported. As compared with cryptococcosis caused by C. neoformans, which is often observed in immunocompromised hosts, cryptococcosis caused by C. gattii occurs predominantly in immunocompetent hosts and is resistant to antifungal drugs. Here, we report a case of refractory cerebral cryptococcoma that was successfully treated by surgical resection of the lesions. A 33-year-old man with no medical history complained of headache, hearing disturbance, and irritability. Pulmonary CT showed a nodular lesion in the left lung. Cerebrospinal fluid examination with Indian ink indicated cryptococcal meningitis, and PCR confirmed infection with C. gattii. C. gattii is usually seen in the tropics and subtropics. Since this patient imported trees and soils from abroad to feed stag beetles, parasite or ...
Tumor necrosis factor alpha (TNF-α) plays a critical role in the control of cryptococcal infection, and its insufficiency promotes cryptococcal persistence. To explore the therapeutic potential of TNF-α supplementation as a booster of host anti-cryptococcal responses, we engineered a C. neoformans strain expressing murine TNF-α. Using a murine model of pulmonary cryptococcosis, we demonstrated that TNF-α-producing C. neoformans strain enhances protective elements of host response including preferential T-cell accumulation and improved Th1/Th2 cytokine balance, diminished pulmonary eosinophilia and alternative activation of lung macrophages at the adaptive phase of infection compared to wild type strain-infected mice. Furthermore, TNF-α expression by C. neoformans enhanced the fungicidal activity of macrophages in vitro. Finally, mice infected with the TNF-α-producing C. neoformans strain showed improved fungal control and considerably prolonged survival compared to wild type strain-infected mice,
Our studies define the elements of a signal transduction cascade that controls the production of virulence factors and pathogenicity ofC. neoformans. The Pka1 catalytic subunit of PKA regulates mating, melanin and capsule production, and virulence. The Pkr1 regulatory subunit of PKA is also a critical component, and mutants lacking Pkr1 overproduced capsule and were hypervirulent by several measures in two different animal models. pkr1 mutant cells also produced dramatically enlarged capsules during infection, and both the larger capsule size and the increased release of immunosuppressive capsular polysaccharides likely contribute to enhanced virulence.. Epistasis analysis further supports the conclusion that the Gα protein Gpa1 is an upstream controlling element for this signaling pathway and that the Ste12α transcription factor may represent one of several downstream targets of PKA that regulate differentiation and virulence. One interesting finding is that mutants with defects in an ...
The study by Baughman and colleagues comprises 2 parts. The first part was a retrospective analysis of 51 patients, the results of which yielded 100% sensitivity and 100% specificity. The second part was a prospective study of 220 patients. 15 were positive for cryptococcal antigen in their BAL fluid, but only 8 of them had culture-proven cryptococcal pneumonia. On the basis of a 3.6% prevalence of cryptococcal infection in this group of patients, a negative predictive value of 100% was calculated. The authors also calculated a positive predictive value of 53% to 67% depending on the cut-point titer of antigen used. Because of the 7 false-positive antigen tests obtained from the prospective study, all antigen-positive and 10 antigen-negative BAL specimens were retested after they were stored at -80 °C for at least 3 months. All culture-positive specimens were antigen positive, but none of the 7 initially false-positive specimens remained positive, thus providing a 100% sensitivity and 100% ...
An article in a recent issue of this journal reported the use of intravenous miconazole in cryptococcosis (1). Use of this new antifungal drug in the treatment of systemic candidiasis as well as cryptococcosis appears to be increasing. Whereas relatively few infectious disease specialists use intravenous miconazole for these indications, we believe that this drug is used much more frequently by physicians working outside the subspecialty of infectious disease. If our impression is correct, then these groups differ in the interpretation of the meager data on the efficacy of miconazole in treating these diseases. Alternatively, some physicians may be relying ...
The case below of systemic cryptococcal infection and meningitis, an opportunistic fungal infection, in a pwMS on fingolimod is one of many cases reported worldwide. The problem with fingolimod is that you cant derisk the risk of opportunistic infections. All cases of opportunistic infection on fingolimod, to the best of my knowledge, have occurred in pwMS with lymphocyte counts above 200/mm3 or 0.2x109/L (the action level ti disruot dosing in the EU). In addition, infections in pwMS on fingolimod are not linked to the peripheral lymphocyte counts. Therefore, the only way to deal with the opportunistic infection risk on fingolimod is to remain vigilant and be aware of symptoms suggsetive of an infection. In the case of cryptococcal meningitis this may be very subtle symptoms; for example a non-specific headache or visual symptoms. The reason why cryptococcal infection is very indolent is simply because people who are immunosuppressed are unable to mount a vigorous immune response against the ...
The endosomal sorting complex required for transport (ESCRT) plays a crucial role in the transportation and degradation of proteins. We determined that Vps27, a key protein of the ESCRT-0 complex, is required for the transport of the virulence factor laccase to the cell wall in Cryptococcus neoformans. Laccase activity was perturbed, as was melanin production, in ... ...

Strains and cell growth: C. neoformans was grown with continuous shaking at 30° in YPD medium [1% (w/v) Bacto yeast extract; 2% (w/v) peptone, 2% dextrose] or minimal medium lacking uracil (Ausubelet al. 2001). Low adenine plates contained yeast nitrogen base supplemented with (per liter) 20 g glucose; 24 mg uracil; 40 mg each arginine, histidine, isoleucine, leucine, lysine, methionine, and tryrosine; 60 mg phenylalanine and tryptophan; 120 mg homoserine; 180 mg valine; and 10 mg adenine. For experiments using 5-fluoroorotic acid (5-FOA), plates contained the same medium with adenine raised to 40 mg/liter and the addition of 1 g/liter 5-FOA. Wild-type serotype D strain B4500 and cap59 strain TYCC33 (Chang and Kwon-Chung 1994) were from Dr. June Kwon-Chung (National Institutes of Health), and ura5 strain JEC43 (Wickeset al. 1997) was from Dr. Joseph Heitman (Duke University Medical Center).

Antibody-mediated defense against pathogens typically requires complex interactions between antibodies and other constituents of the humoral and cellular immune systems. However, recent evidence indicates that some antibodies alone can inhibit pathogen function in the absence of complement, phagocytes, or NK cells. In this issue of the JCI, McClelland et al. have begun to elucidate the molecular bases by which antibodies alone can impact pathogen growth and metabolism. They show that mAbs specific for the polysaccharide capsule of the human pathogenic fungus Cryptococcus neoformans elicit diverse effects on fungal gene expression, lipid biosynthesis, susceptibility to amphotericin B, cellular metabolism, and protein phosphorylation. These data suggest that pathogens have the capacity to generate broad metabolic responses as a result of surface binding by pathogen-specific antibodies, effects that may hold therapeutic promise. ...

Infection wif C. neoformans is termed cryptococcosis. Most infections wif C. neoformans occur in de wungs.[12] However, fungaw meningitis and encephawitis, especiawwy as a secondary infection for AIDS patients, are often caused by C. neoformans, making it a particuwarwy dangerous fungus. Infections wif dis fungus are rare in dose wif fuwwy functioning immune systems.[13] So, C. neoformans is sometimes referred to as an opportunistic fungus.[13] It is a facuwtative intracewwuwar padogen[14] dat can utiwize host phagocytes to spread widin de body.[15][16] Cryptococcus neoformans was de first intracewwuwar padogen for which de non-wytic escape process termed vomocytosis was observed.[17][18] It has been specuwated dat dis abiwity to manipuwate host cewws resuwts from environmentaw sewective pressure by amoebae, a hypodesis first proposed by Arturo Casadevaww under de term accidentaw viruwence.[19].

The researchers findings, printed within the Worldwide Journal of Antimicrobial Agents, indicate that fendiline hydrochloride can stimulate white-colored bloodstream cells to battle cryptococcosis, which can be more efficient than using drugs to directly get rid of the fungus.. Despite its effectiveness, a lesser dose (1 µM) of fendiline hydrochloride well suited for clinical use unsuccessful to avoid C. neoformans growth.. In reaction, the scientists screened 1,200 Food and drug administration-approved drugs to recognize effective compounds that could stimulate white-colored bloodstream cells to acknowledge and kill C. neoformans residing in cells, the discharge stated. Throughout a preliminary screening, 19 compounds put together to considerably hinder intra cellular development of C. neoformans. After additional screening processes ruling out compounds with host cell toxicity, the scientists discovered that fendiline hydrochloride, dosed at 5 µM, considerably enhanced phagosomal ...
The difference between these strains could make a difference in treatment, clinical course, and outcome, said Joseph Heitman, MD, PhD, senior author of the study and chair of the Duke Department of Molecular Genetics and Microbiology.. The study was published September 1 in PLoS Pathogens.. The study emphasizes that health professionals need to record the cryptococcal species more carefully to understand different clinical courses and possibly to change treatment strategies.. Researchers at Duke University Medical Center discovered that in the Los Angeles area, more than 12 percent of AIDS patients diagnosed with Crypotococcus were infected with C. gattii, much higher than earlier studies, which suggested that only about 1 percent have C. gattii. The researchers based these figures on molecular testing of fungal DNA barcodes.. This discovery comes at the same time as a C. gattii outbreak is expanding in the Pacific Northwest, spreading southward from Vancouver, British Columbia, through ...

Cryptococcus neoformans (C. neoformans) is a major opportunistic fungal pathogen in individuals with impaired T cell-mediated immunity. Notch pathway is an important signaling component of immunological synapse during APC/T-cell engagement. Little is known about the role of Notch signaling in fungal infections. We sought to determine the role of Notch signaling in C. neoformans infection. Wild-type C57BL/6 (WT) and CD4-Cre+×ROSA DNMAML (DNMAML) mice were infected intratracheally infected with C. neoformans. The fungal burden, leukocyte recruitment, and cytokine profile were assessed at 3 and 6 weeks post-infection (wpi). A 50-fold greater fungal burden was detected in both lungs and brains of DNMAML mice compared to those in the WT mice at 6 wpi. Although, equivalent fungal burdens were found at 3 wpi in WT and DNMAML groups, the production of IFN-γ, IL-4, and IL-13 was significantly decreased in lung leukocytes of DNMAML mice. In contrast, an equivalent induction of IL-17 was observed in both ...

Giant cells called titan cells created by the fungus Cryptococcus neoformans protect the fungus during infection, according to two University of Minnesota researchers. Kirsten Nielsen, Ph.D., an assistant professor in the department of microbiology, and recent Ph.D. recipient Laura Okagaki believe their discovery could help develop new ways to fight infections caused by Cryptococcus. The findings will be published in the June 2012 issue of the journal Eukaryotic Cell. Cryptococcus, a fungus frequently found in dust and dirt, is responsible for the deaths of more than 650,000 AIDS patients worldwide each year. It is also a potentially deadly concern among chemotherapy and organ transplant patients. Currently, Cryptococcus causes more annual deaths in sub-Saharan Africa than tuberculosis. While most healthy individuals are resistant to Cryptococcus infections, the fungus can cause deadly disease for those with already weak immune systems, said Dr. Nielsen. When inhaled, Cryptococcus can cause ...

The development of new drugs to fight a common fungal pathogen which kills half a million people globally each year is a step closer thanks to a University of Queensland-led study.. UQ PhD student Jessica Chitty of the Australian Infectious Diseases Research Centre, School of Chemistry and Molecular Biosciences, said the study targeted the fungus Cryptococcus neoformans, which had shown signs of becoming resistant to current medications.. This is a fungus that can be found around the world and when inhaled, its microscopic cells can cause infection in people with a weakened immune system, she said.. Infections are particularly prevalent in people with advanced AIDS but can also occur in transplant recipients and those on immunosuppressive medication.. Recently two rare cases of Cryptococcus neoformans infections occurred in Australia in immunocompetent people.. Co-author Associate Professor James Fraser said drugs used to treat the disease have been around for a few decades and consequently ...
