Fatal Disseminated Coccidioidomycosis in Cirrhosis: A Case Series

Abstract

PurposeCoccidioidomycosis is endemic to the Southwest United States and Mexico. In this case series we describe 3 cases, occurring in the Southwest United States, of patients with disseminated coccidioidomycosis infection in cirrhosis, all with a miliary pattern present on chest imaging. MethodsThis case series was performed conducting a review of patients’ electronic health records and thorough review of the literature for coccidioidomycosis infection in patients with liver disease. ResultsThree patients with different etiology of liver disease with Model for End-stage Liver Disease – Sodium (MELD-Na) scores >20 had chest imaging findings indicative of a miliary pattern on presentation. Each patient subsequently had extensive infectious disease workup that showed evidence of disseminated coccidioidomycosis. All 3 patients clinically worsened and eventually died. ConclusionsThis case series highlights the severity of disseminated coccidioidomycosis in patients with cirrhosis in an endemic area, as well as potential early clues such as miliary patterns on chest imaging. A review of the literature found a significant connection among potential mechanisms describing why patients with cirrhosis have such adverse outcomes in the setting of disseminated coccidioidomycosis, including cirrhosis-associated immune dysfunction and genetic defects in immune functioning.
