Cryptococcal meningitis is a life-threatening condition caused by an invasive, opportunistic, encapsulated saprophytic fungus, either Cryptococcus neoformans or gattii most often in immunocompromised patients, especially those with human immunodeficiency virus (HIV). Overwhelming invasive infection of immunocompetent patients rather uncommon, and diagnosis challenging due to more indolent cours...
cryptococcosis has become the fourth leading life-threatening opportunistic infection in patients with aids, but also occurs in non-aids patients. in view of the increasing numbers of infection during last decade in iran, use of rapid, sensitive and specific test for diagnosis of cryptococcal disease has become important than ever. we aimed to produce the reagents for latex cryptococcal antigen...
BACKGROUND Detection of subclinical cryptococcal disease using cryptococcal antigen screening among HIV-positive individuals presents a potential opportunity for prevention of both clinical disease and death if patients with detectable cryptococcal antigen are identified and treated pre-emptively. Recently developed point-of-care cryptococcal antigen tests may be useful for screening, particula...
BACKGROUND Cryptococcal meningitis is a leading cause of death in patients with acquired immunodeficiency syndrome and contributes substantially to the high early mortality in antiretroviral treatment (ART) programs in low-resource settings. Screening for cryptococcal antigen in patients who enroll in ART programs may identify those at risk of cryptococcal meningitis and permit targeted use of ...
BACKGROUND Cryptococcal disease is estimated to be responsible for significant mortality in Sub-Saharan Africa; however, only scarce epidemiology data exists. We sought to evaluate the prevalence of and risk factors for cryptococcal antigenemia in Ethiopia. METHODS Consecutive adult HIV-infected patients from two public HIV clinics in Addis Ababa, Ethiopia were enrolled into the study. A CD4 ...
BACKGROUND Cryptococcal infection is a common opportunistic infection among severely immunosuppressed HIV patients and is associated with high mortality. Positive cryptococcal antigenemia is an independent predictor of cryptococcal meningitis and death in patients with severe immunosuppression. We evaluated the prevalence and factors associated with cryptococcal antigenemia among patients with ...
BACKGROUND This study aimed to evaluate the prevalence and predictors of AIDS-related complicated cryptococcal meningitis. The outcome was complicated cryptococcal meningitis: prolonged (>/= 14 days) altered mental status, persistent (>/= 14 days) focal neurologic findings, cerebrospinal fluid (CSF) shunt placement or death. Predictor variable operating characteristics were estimated using rece...
We conducted a retrospective, multicenter study evaluating the safety of discontinuing maintenance therapy for cryptococcal meningitis after immune reconstitution. Inclusion criteria were a previous definitive diagnosis of cryptococcal meningitis, a CD4 cell count of >100 cells/microL while receiving highly active antiretroviral therapy (HAART), and the subsequent discontinuation of maintenance...
Cryptococcus neoformans is an opportunistic pulmonary fungal pathogen that disseminates to the CNS causing fatal meningitis in immunocompromised patients. Dendritic cells (DCs) phagocytose C. neoformans following inhalation. Following uptake, cryptococci translocate to the DC lysosomal compartment and are killed by oxidative and non-oxidative mechanisms. DC lysosomal extracts kill cryptococci i...
Cryptococcal meningitis is an opportunistic infection in immunosuppressed hosts with high morbidity and mortality. Once suffering from cryptococcal meningitis, immunocompetent patients are more likely to achieve poor outcome, because of the powerful immune response. Here we present a case of cryptococcal meningitis occurring in an immunocompetent host with no definite underlying diseases and no...
