ABSTRACT
Chikungunya nephropathy is an uncommon etiology of acute kidney injury, associated with the mosquito-borne chikungunya arbovirus (CHIKV). The very limited number of pathologic reports to date have only involved postmortem analyses. We here report 5 cases of acute kidney injury for which kidney biopsies were performed in patients with confirmed acute CHIKV infection, during the recent outbreak of chikungunya disease in the French West Indies. The patients ranged from 42 to 76 years of age. All of the patients developed kidney injury, 3 of whom required short-term dialysis and underwent a kidney biopsy. Analysis of kidney biopsies revealed 2 main histopathologic patterns acute interstitial nephritis with predominant lymphoid inflammation and acute tubular injury. Epithelioid granulomas were observed in 2 cases. There were no glomerular lesions, except in biopsies from 2 patients, including 1 with a previous known primary focal segmental glomerulosclerosis. CHIKV antigen immunofluorescence microscopy revealed staining in tubular cells. In all of the cases, the short-term outcome was favorable, with recovery of kidney function.
