Segunda biopsia renal en nefritis lúpica: cambios histopatológicos

These results show that therapeutically relevant switches from proliferative to non-proliferative lesions are a rare event and a second biopsy during a lupus nephritis flare could prove unnecessary in many cases. In the cases of a non-proliferative lesion in the reference biopsy, class switches are frequently found and repeat biopsies are advisable.
