Coccidioidomycosis in a 38‑year‑old man: a case report

Abstract

The present article describes a case of acute pulmonary coccidioidomycosis in a 38-year-old man, a research worker. The disease started during the patient stay in Arizona, USA, and clinical symptoms persisted after his return to Poland. Acute coccidioidomycosis is one the clinical manifestations of Coccidioides immitis strain endemic infections occurring in the south-western regions of USA including California (mainly San Joaquin Valley), Western Texas, New Mexico and the desert areas of Arizona, and Central and South America. The native environment of Coccidioides immitis is soil penetrated by rodents. People, domestic and wild animals suffer from coccidioidomycosis. The infection rate in endemic areas is about 2-4% a year in the healthy population. Coccidioidomycosis can be observed in non-endemic areas due to population mobility and in immunocompromised patients. The Coccidioides immitis infection is caused by inhaled airborne fungal spores and it may occur as primary pulmonary (acute or chronic) asymptomatic form, meningitis, or disseminated disease. The clinical symptoms of coccidioidomycotis like acute pulmonary manifestations may resemble typical, resistant to empiric antibiotic treatment of bacterial pneumonia. In healthy subjects, pulmonary coccidioidomycosis may occur as asymptomatic infection, which resolves spontaneously without medication. Sometimes, slight shadows like local fibrosis and cavities may be visible on the chest X-ray. The Coccidioides immitis infection in people with immunological deficiency syndromes, e.g. HIV/AIDS, manifests itself as disseminated disease and may lead to severe complications including death.
