IgA nephropathy and hypercalcemia in Whipple's disease.

Abstract

In 2 patients an IgA nephropathy was found 2 and 5 years before gastrointestinal symptoms led to the diagnosis of Whipple's disease. One patient additionally presented with hypercalcemia. Subsequently 1 patient died, whereas treatment with trimethoprim/sulfamethoxazole resulted in an improvement of IgA nephropathy and in a complete recovery from hypercalcemia and all the manifestations of Whipple's disease in the other patient. IgA nephropathy and hypercalcemia may be considered as early manifestations of Whipple's disease.
