To biopsy or not to biopsy: Henoch-Schönlein nephritis in children, a 5-year follow-up study.

Children with early KB at diagnosis seem to have a better renal outcome at 5 years compared to those without an early biopsy at diagnosis or biopsied later. However, this is a small patient cohort and data are missing. Further work is needed to build consensual guidelines on the management of HSPN in children.
