Cryptococcosis in Previously Healthy Adults Study of Immune and Genetic Factors in Cryptococcal Infection

What this Trial Is About

Cryptococcosis is a fungal infection that mainly affects people with weakened immune systems, like those with AIDS or organ transplants, but about one-third of cases occur in individuals without known immune problems. This research focuses on understanding immune system defects and genetic factors that may make previously healthy adults susceptible to cryptococcosis. The study aims to explore the pathophysiology and immune responses in these patients, including genetic screening of their relatives and comparison with healthy volunteers. Participants include three groups: previously healthy adults diagnosed with cryptococcosis without known immune defects, their blood relatives, and healthy adult volunteers. Various samples such as blood, saliva, cerebrospinal fluid, eyebrow hair, and nail clippings will be collected. Patients will receive standard medical care and may receive corticosteroids or immunosuppressive treatments if inflammation causes neurological damage. Genetic and immunologic testing will be performed to identify immune abnormalities and genetic susceptibility. Participants will be closely monitored with various tests to understand disease progression and immune responses. Healthy volunteers and relatives will also undergo testing to serve as comparison groups. The study will measure clinical disease spectrum and investigate immunological and genetic mechanisms over 1 to 5 years. Participants may be seen frequently as needed to manage their condition, and samples will be stored for future research.
