Cryptococcosis

Cryptococcosis is a potentially fatal fungal infection of mainly the lungs, presenting as a pneumonia, and brain, where it appears as a meningitis. Cough, difficulty breathing, chest pain and fever are seen when the lungs are infected. When the brain is infected, symptoms include headache, fever, neck pain, nausea and vomiting, light sensitivity and confusion or changes in behavior. It can also affect other parts of the body including skin, where it may appear as several fluid-filled nodules with dead tissue.

It is caused by the fungi Cryptococcus neoformans or less commonly Cryptococcus gattii, and is acquired by breathing in the spores from the air. These fungi are found around the world in soil, decaying wood, pigeon droppings, and in the hollows of some species of trees. Whereas C. neoformans infects generally people with HIV/AIDS and those on immunosuppressant drugs and does not usually affect fit and healthy people, C. gattii (found in some parts of Canada and the US) does. Once breathed in, the dried yeast cells colonize the lungs, where they are either cleared by immune cells, lie dormant, or cause infection and spread.

Diagnosis is by isolating Cryptococcus from a sample of affected tissue or direct observation of the fungus by using staining of body fluids. It can be cultured from a cerebrospinal fluid, sputum, and skin biopsy. Treatment is with fluconazole or amphotericin B.

Data from 2009 estimated that of the almost one million cases of cryptococcal meningitis that occurred worldwide annually, 700,000 occurred in sub-Saharan Africa and 600,000 per year died. Cryptococcosis was rare before the 1970s which saw an increase in at-risk groups such as people with organ transplant or on immunosuppressant medications. The number of cases escalated in the mid-1980s with over 80% occurring in people with HIV/AIDS. Pigeon breeders (or otherwise people who spend significant time with pigeons, known as "pigeon fanciers") are known to have a high incidence of cryptococcal infections including PCC due to Cryptococcus' association with pigeon droppings.
