ABSTRACT

Background: Coccidioidomycosis is a systemic fungal disease caused by Coccidioides spp. Patients with phagocytic, cellular, or humoral immunodeficiencies exhibit immunodeficiencies that confer increased susceptibility to fungal infections. In Mexico there is an underreporting of this disease and no studies currently describe the immune status of these patients in an endemic area. Objective: To describe the clinical and immunological characteristics of pediatric patients with coccidioidomycosis. Materials and methods: Pediatric patients with diagnosis of coccidioidomycosis from two tertiary level hospitals of northeastern Mexico were included, from the period 2008-2012; immune status was assessed by clinical history, immunoglobulins levels, levels of lymphocytes T, B, and NK (natural killer), and the nitroblue tetrazolium test. Results: Thirty patients were included, 18 male (60%). The age at diagnosis was five years (median, range 0.25-13). Twelve were from Coahuila (40%). Residual pulmonary coccidioidomycosis was the clinical type presentation found in 16 patients (53%). A primary humoral immunodeficiency was found in three patients (10%) and a secondary immunodeficiency in another three (10%). Case fatality rate was 16%. Conclusions: The disease predominated in male patients. In 33% of patients, levels of IgG were elevated, probably due to stimulation by chronic fungal infection. In 20% of patients, immunodeficiency was documented. There was a high mortality rate.
