Update on Pulmonary Cryptococcosis.

Mycopathologia 2021 Jun 28. Epub 2021 Jun 28.

Department of Biology, McMaster University, Hamilton, L8S 4K1, Canada.

Pulmonary cryptococcosis is a common but underdiagnosed opportunistic fungal infection in both immunocompromised and immunocompetent patients. The causal agents include at least eight evolutionary distinct haploid lineages as well as their hybrids of the human pathogenic Cryptococcus complex. In this update, we review recent advances in epidemiology, mode of transmission, risk factors, diagnostic methods, and therapy of pulmonary cryptococcosis. Read More

Internal Medicine, University of California Irvine, Orange, USA.

Cryptococcosis is an invasive fungal disease that most commonly affects immunocompromised individuals, typically causing pulmonary and central nervous system (CNS) symptoms. The fungus that causes cryptococcosis, is globally disseminated and often transmitted through bird droppings. The two most frequent and pertinent species responsible for clinical infections in humans include , which has been known to cause the majority of cryptococcosis globally until recently, during which has been identified and reported more frequently.

is the leading cause of cryptococcosis, an invasive and potentially fatal infectious disease. Therapeutic failures are due to the increase in antifungal resistance, the adverse effects of drugs, and the unavailability of therapeutic regimens in low-income countries, which limit the treatment of cryptococcosis, increasing the morbidity and mortality associated with these infections. Thus, new antifungal drugs and innovative strategies for the cryptococcosis treatment are urgently needed. Read More

Fingolimod-related cryptococcal meningoencephalitis and immune reconstitution inflammatory syndrome in a patient with multiple sclerosis.

Mult Scler Relat Disord 2021 Jun 5;53:103072. Epub 2021 Jun 5.

Maxine Mesinger Multiple Sclerosis Comprehensive Care Center, Department of Neurology, Baylor College of Medicine, Houston, Texas, United States.

Medical Mycology Laboratory, Department of Plant Production and Microbiology, University Miguel Hernández, Campus of Sant Joan D'Alacant, 03550, Alicante, Spain.

Members of the Cryptococcus gattii species complex are notorious causes of cryptococcosis as they often cause severe, life-threatening infections. Here we describe a case of a severe disseminated C. deuterogattii infection in a previously healthy patient who was initially treated with amphotericin B, 5-fluorocytosine and fluconazole, which led to a good neurological response, but the infection in the lungs remained unaltered and was not completely resolved until switching the antifungal therapy to isavuconazole.

Centre d'Investigation Clinique, Inserm CIC 1424, Centre Hospitalier de Cayenne, 97300 Cayenne, French Guiana.

Although the burden of histoplasmosis in patients with advanced HIV has been the focus of detailed estimations, knowledge about invasive fungal infections in patients living with HIV in an Amazonian context is somewhat scattered. Our goal was thus to adopt a broader view integrating all invasive fungal infections diagnosed over a decade in French Guiana. All patients hospitalized at Cayenne hospital from 1 January 2009 to 31 December 2018 with a proven diagnosis of invasive fungal infection were included (N = 227). Read More

The human pathogenic species are the main agents of fungal meningitis in humans and the causes of other diseases collectively called cryptococcosis. There are at least eight evolutionary divergent lineages among these agents, with different lineages showing different geographic and/or ecological distributions. In this review, we describe the main strain typing methods that have been used to analyze the human pathogenic and discuss how molecular markers derived from the various strain typing methods have impacted our understanding of not only cryptococcal epidemiology but also its evolutionary histories.
