IgA nephropathy occurrence, treatment, and prognosis in the last two decades in Denmark

The annual incidence of IgAN in Denmark increased during the study period. At the time of biopsy, many patients had preserved kidney function and substantial albuminuria. The risk of KFRT and mortality was substantial, and overall, the prognosis for Danish IgAN patients did not improve over the past two decades.

Abstract

The annual incidence of IgAN in Denmark increased during the study period. At the time of biopsy, many patients had preserved kidney function and substantial albuminuria. The risk of KFRT and mortality was substantial, and overall, the prognosis for Danish IgAN patients did not improve over the past two decades.
