Eculizumab in dense-deposit disease after renal transplantation.

Background: Dense-deposit disease (DDD) is a rare glomerulopathy characterized by electron-dense deposits in the glomerular basement membrane. About 50 % of patients with DDD progress to end-stage kidney disease and require dialysis within 10 years of diagnosis, and the disease often recurs after renal transplantation.

Case-diagnosis/treatment: We describe a 14-year-old girl with recurrent DDD in her transplanted kidney.

Association of C4d deposition with clinical outcomes in IgA nephropathy.

Background And Objectives: Several studies have suggested that activation of the complement system is a contributing pathogenic mechanism in IgA nephropathy (IgAN). C4d staining is an inexpensive and easy-to-perform method for the analysis of renal biopsies. This study aimed to assess the clinical and prognostic implications of C4d staining in IgAN.

Clofazimine as elective treatment for granulomatous cheilitis.

Cheilitis granulomatosa (CG) is a rare, idiopathic inflammatory disorder that usually affects young adults and clinically is characterized by diffuse, non-tender, soft to firm swelling of one or both lips. A variant of granulomatous cheilitis is Melkersson-Rosenthal syndrome when associated with facial paralysis and furrowed tongue. Several treatments have been used with variable success.
