Another name for active PCP infection.

pneumocystosis
[no̅o̅′mōsistō′sis]
Etymology: Gk, pneuma, air, kystis, bag, osis, condition
infection with the fungus Pneumocystis jiroveci, usually seen in patients with human immunodeficiency virus infection; premature, malnourished infants; or debilitated or immunosuppressed people, particularly those with hematologic malignancies. It is characterized by fever, cough, tachypnea, and frequently cyanosis. The diagnosis is difficult to make and usually requires obtaining a specimen by an induced sputum procedure or bronchoalveolar lavage and special staining techniques. Mortality rates are near 100% in untreated patients. Treatment with pentamidine isethionate or a combination of trimethoprim and sulfamethoxazole, trimetrexate plus folic acid, trimethoprim plus dapsone, atovaquone, or primaquine plus clindamycin is effective. Patients at risk should receive prophylaxis against acute infection. Also called interstitial plasma cell pneumonia.

pneumocystosis
1. pneumonia characterized by interstitial accumulation of plasma cells.
2. pneumonia caused by Pneumocystis carinii infection; usually latent or sucbclinical except in immunocompromised humans, dogs, cats, pigs, horses, goats, primates, rabbits.

She was put on highly active antiretroviral therapy (HAART) with DDI (200 mg administered once daily), D4T (40 mg administered twice daily), and NFV (750 mg tid) and prophylaxis against pneumocystosis and toxoplasmosis with co-trimoxazole.
001) after recovery from pneumocystosis; baseline CD4+ count [greater than or equal to] 50 cells/[micro]L and first episode of pneumocystosis were the principal host factors associated with this rise (both p<0.
Today, we know that human pneumocystosis is anthroponotic.
