OBJECTIVES Cryptococcus neoformans is the most incriminated fungal pathogen causing meningitis in acquired immune deficiency syndrome (AIDS) patients, and is known to constitute a major cause of deaths in AIDS patients. This study thus aimed to determine the baseline sero-prevalence of Cryptococcus neoformans infection in anti-retroviral naïve (ART-naïve) AIDS patients using the serum Cryptococ...
INTRODUCTION Cryptococcal meningitis is one of the leading causes of death among people with HIV in Africa, primarily due to delayed presentation, poor availability and high cost of treatment. Routine cryptococcal antigen (CrAg) screening of patients with a CD4 count less than 100 cells/mm3, followed by pre-emptive therapy if positive, might reduce mortality in high prevalence settings. Using t...
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...
Diagnostic tools for invasive fungal infections have continuously improved within the last decades. Nowadays, cultural methods, antigen testing, and molecular tests, such as polymerase chain reaction, are widely used. These methods, however, are accompanied with different limitations as various availability, various turnaround time or high costs. A new generation of point-of-care test has shown...
A major ceramide monohexoside (CMH) was purified from lipidic extracts of Cryptococcus neoformans. This molecule was analyzed by high-performance thin-layer chromatography (HPTLC), gas chromatography coupled with mass spectrometry, and fast atom bombardment-mass spectrometry. The cryptococcal CMH is a beta-glucosylceramide, with the carbohydrate residue attached to 9-methyl-4,8-sphingadienine i...
BACKGROUND HIV-infected persons with detectable cryptococcal antigen (CrAg) in blood have increased morbidity and mortality compared with HIV-infected persons who are CrAg-negative. This study examined neurocognitive function among persons with asymptomatic cryptococcal antigenemia. METHODS Participants from three prospective HIV cohorts underwent neurocognitive testing at the time of antiret...
Sir, Cryptococcosis is an opportunistic infection caused by Cryptococcus neoformans and is usually seen in immunocompromised patients. Histopathologically, the skin lesions are divided into two types, i.e. cystic and granulomatous lesions (1, 2), each of which occurs exclusively depending on the conditions of individual hosts (3). For unknown reason the titre of cryptococcal antigen in patients...
