What is cryptococcosis?

Cryptococcosis is a disease caused by infection with Cryptococcus neoformans , a fungus commonly found in bird feces and soil. This condition can be fatal if left untreated, especially for patients who have a compromised immune system. The incidence of cryptococcosis in the general population is very low, since most people can resist infection with this fungus.

Classically, people develop cryptococcosis because they inhale the spores of the fungus. The spores colonize the lungs, causing pneumonia-like symptoms such as chest pain, cough, shortness of breath, and fatigue. In some patients, the infection can spread to other areas of the body, with the fungus colonizing various organs and other tissues. These situations can become extremely dangerous very quickly, as the fungus will interfere with normal organ function.

Some cases of cryptococcosis manage to jump to the nervous system, allowing the fungus to reach the brain. These cases are usually fatal, as the fungus destroys the brain and neurological symptoms can take a long time to appear. When the patient's confusion, blurred vision, shaky hands, and other neurological symptoms can be traced back to cryptococcosis, the damage may have progressed too far.

People can also develop this condition when fungal spores get into cuts and abrasions on their bodies, causing cutaneous cryptococcosis. This can cause large sores and raised skin growths. The spores can also spread through the wound into the body, where they can spread to vital organs. Classically, people develop cutaneous forms of the disease as a result of contact with infected birds or soil.

The symptoms of cryptococcosis do not always appear, and they usually appear late. Because this condition is relatively rare, a doctor may not immediately connect the symptoms to the disease, unless the patient has AIDS or another condition that has resulted in a compromised immune system, and the doctor is highly experienced in the treatment of these patients. Patients who have a weakened immune system should make sure they are working with trained and experienced doctors who can recognize the signs of dangerous infections early.

The treatment for cryptococcosis is the aggressive administration of antifungal medications that are designed to kill the fungus and prevent it from spreading. The patient may also receive supportive care, such as ventilation with a ventilator, if they are having trouble breathing independently. The prognosis for patients with this condition is greatly improved if they are diagnosed early and action is taken quickly.
