Prevalence of coccidioidomycosis in cystic fibrosis patients residing in Southern Arizona.

UNLABELLED: Sparse data exists about patients with cystic fibrosis (CF) and their risk of contracting coccidioidiomycosis or Valley Fever, which is highly endemic in southern Arizona. A retrospective review of medical records of 79 adult CF patients residing in Arizona was performed. Two cases only of coccidioidomycosis were documented between in the 790 patient years. However, false-positive serologies were found in 15 patients. This 10-year retrospective review of 79 adult CF patients found that there was a lower prevalence of coccidioidomycosis in CF patients compared to that of the general population of the area.

LAY SUMMARY: Patients with cystic fibrosis (CF) suffer from chronic lung infection. Little is known about CF and fungal infection. Coccidioidomycosis is a fungal infection common in Arizona and this study shows a lower infection rate from Coccidioidomycosis in CF patients compared to the general population.
