Hyperuricemia-associated Mesoamerican Nephropathy: Case Report and Review of Literature.

Mesoamerican nephropathy (MeN), formerly called chronic kidney disease of unknown cause (CKDu), refers to chronic kidney disease (CKD) that presents in young and middle-aged Central Americans in the absence of any clear etiology. MeN is a relatively new diagnosis with rapidly rising prevalence in specific regions of El Salvador and Nicaragua, Guatemala, and Costa Rica. It is seldom associated with hyperuricemia. We present a case of a patient with gouty arthritis and hyperuricemia with associated CKD due to MeN. We also provide a review of literature of this disease.
