Less commonly it may affect other organs such as the eye or prostate. neoformans chiefly infects the skin, lungs, and central nervous system (causing meningitis). The prevalence of cryptococcosis has been increasing over the past 50 years for many reasons, including the increase in incidence of AIDS and the expanded use of immunosuppressive drugs. Other conditions that pose an increased risk include certain malignancies (such as lymphoma), liver cirrhosis, organ transplants, and long-term corticosteroid therapy. Cause Ĭryptococcosis is a common opportunistic infection for AIDS, and is particularly common among people living with AIDS in Africa. Symptom onset is often sudden when lungs are infected and gradual over several weeks when the central nervous system is affected. Depending on the site of infection, other features may include loss of vision, blurred vision, inability to move an eye and memory loss. In the skin, it may appear as several fluid-filled nodules with dead tissue. It can also affect other parts of the body including skin, eyes, bones and prostate. When the brain is infected, symptoms include headache, fever, neck pain, nausea and vomiting, light sensitivity, confusion or changes in behaviour. Signs and symptoms Ĭough, shortness of breath, chest pain and fever are seen when the lungs are infected, appearing like a pneumonia.
It typically begins in the lungs before spreading to other parts of the body, particularly the brain and nervous system. Classification Ĭryptococcus is generally classified according to how it is acquired and its site. Pigeon breeders (or otherwise people who spend significant time with pigeons) are known to have a high incidence of cryptococcal infections including PCC due to Cryptococcus' association with pigeon droppings. The number of cases escalated in the mid-1980s with over 80% occurring in people with HIV/AIDS. Cryptococcosis was rare before the 1970s which saw an increase in at-risk groups such as people with organ transplant or on immunosuppressant medications. ĭata 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. Treatment is with fluconazole or amphotericin B.
CRYPTOCOCCAL MENINGITIS CSF FINDINGS SKIN
It can be cultured from a cerebrospinal fluid, sputum, and skin biopsy. ĭiagnosis is by isolating Cryptococcus from a sample of affected tissue or direct observation of the fungus by using staining of body fluids. 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. Whereas C. neoformans generally infects 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. These fungi are found around the world in soil, decaying wood, pigeon droppings, and in the hollows of some species of trees. It is caused by the fungi Cryptococcus neoformans or less commonly Cryptococcus gattii, and is acquired by breathing in the spores from the air. It can also affect other parts of the body including skin, where it may appear as several fluid-filled nodules with dead tissue. When the brain is infected, symptoms include headache, fever, neck pain, nausea and vomiting, light sensitivity and confusion or changes in behavior. Cough, difficulty breathing, chest pain and fever are seen when the lungs are infected. Ĭryptococcus neoformans, Cryptococcus gattii Ĭryptococcosis is a potentially fatal fungal infection of mainly the lungs, presenting as a pneumonia, and brain, where it appears as a meningitis. Brain: Headache, fever, neck pain, nausea, vomiting, light sensitivity, confusion, change in behaviour.Lung: Cough, difficulty breathing, chest pain and fever.
