Individuals with a positive culture of Cryptococcus neoformans 18 years of age and older without HIV infection or other condition predisposing to cryptococcosis (such as high-dose corticosteroid therapy, sarcoidosis, or a blood cancer) may be eligible for this study. Candidates who test positive for HIV infection may not participate.
Participants will have a physical examination, medical history, routine blood tests and assessment of disease activity upon entering the study. Patients who may have active cryptococcosis will also have a lumbar puncture (spinal tap) and additional blood tests. Following the initial evaluation, patients receiving treatment for cryptococcosis will come to the NIH Clinical Center as needed to manage their disease, typically no less than every 3 months. Other patients will be seen every 6 to 12 months. The visits will include a medical history, physical examination, and blood and urine tests.

INCLUSION CRITERIA: Patients: Patients must: 1. Have cryptococcosis as determined by information collected from their medical records, telephone interviews or from a referring physician: -histopathology showing cryptococci; or -culture of C. neoformans or C. gattii -a positive cryptococcal antigen in the serum and/or CSF, together with CSF cell count and chemistry consistent with cryptococcal meningitis. 2. Be over the age of 18 years old. 3. Have a primary physician outside of the NIH. 4. Agree to undergo genetic testing that will include WES and high density SNP arrays as appropriate for possible WES linkage studies. 5. Allow samples to be stored for future research. 6. Pregnant patient willnot be excluded; However, research procedures greater than minimal risk including bone marrow biopsy and apheresis would not be performed on pregnant subjects. Otherwise, pregnant patients with cryptococcus would be treated as per standard of care, minimizing teratogenic potential of drugs and ionizing radiation whenever possible. Genetic Relatives of Patients: Genetic relatives must: 1. Be a genetic relative of a patient enrolled in this study 2. Be over the age of 18 years old 3. Agree to undergo genetic testing that may include WES and high density SNP analysis 4. Allow samples to be stored for future research Healthy Volunteers: Healthy volunteers must: 1. Be between the ages of 18 and 70 years old 2. Allow samples to be stored for future research EXCLUSION CRITERIA: Patients Patients will be excluded for any of the following: 1. The presence of certain types of acquired abnormalities of immunity due to: -HIV -Cancer chemotherapeutic agent(s) -An underlying malignancy could be grounds for possible exclusion of a patient if in the opinion of the investigator, the underlying disease predisposed the patient to the infection -Monoclonal antibody therapy directed against a patient s immune system 2. Any condition that in the medical opinion of the investigator may interfere with the evaluation of a co-existing abnormality of immunity that is exclude patients with Cushing s disease that have very high cortisol levels at the time of diagnosis of their cryptococcosis. Genetic Relatives of Patients: Genetic relatives will be excluded for the following: -Pregnancy -Any condition that in the medical opinion of the investigator may interfere with evaluation of an immune system abnormality that is the subject of study under this protocol. Healthy Volunteers: Healthy volunteers will be excluded for any of the following: 1. History of HIV or viral hepatitis (B or C). 2. History of recurrent or severe infections. 3. History of intravenous drug use. 4. History of engaging in high risk activities for exposure to HIV; 5. Receiving chemotherapeutic agent(s), immunosuppressants or have underlying malignancy. 6. Pregnancy. 7. Have history of heart, lung, kidney disease, or bleeding disorders. 8. Any condition that in the medical opinion of the investigator may interfere with evaluation of an immune system abnormality that is the subject of study under this protocol.
