ABSTRACT
Cryptococcosis is a fungal infection burdened by a high case-fatality rate in immunocompromised patients. Once limited to human immunodeficiency virus (HIV)-infected patients, the epidemiology of cryptococcosis has evolved in recent years and new risk factors have emerged. It is therefore essential to identify these risk factors in order to improve prevention and therapeutic efficacy. We conducted a retrospective observational study including all cases of cryptococcosis between January 2016 and December 2022, diagnosed at the University Hospital of Marseille. During the study period 15 cases of cryptococcosis were diagnosed. Six patients were HIV-infected. Nine patients had one or more comorbidities including liver cirrhosis, type 2 diabetes mellitus, primary immunodeficiency disorder, chronic lymphocytic leukemia and solid organ transplantation. Ten patients had central nervous system cryptococcosis, four had pulmonary cryptococcosis and one patient had extra-pulmonary disseminated cryptococcosis. Of the three patients with liver cirrhosis, two patients died with a post-mortem diagnosis. Our data suggest that emerging risk factors are probably underestimated by clinicians. It emphasizes the need for cryptococcal antigenemia as part of syndromic investigation of any unexplained fever or neurological symptoms in an at-risk patient. Early diagnosis and treatment are essential for patient's survival.
