摘要

BACKGROUND Interferons(IFNs)are characterized by a wide range of biological effects,which justifies their potential therapeutic use in several pathologies,but also elicit a wide array of adverse effects in almost every organ system.Among them,renal involvement is probably one of the most complex to identify.CASE SUMMARY We describe four cases of kidney damage caused by different IFN formulations:IFN-β-related thrombotic microangiopathy,IFN-β-induced systemic lupus erythematosus,and two cases of membranous nephropathy secondary to pegylated-IFN-α2B.In each case,we carefully excluded any other possible cause of renal involvement.Once suspected as the casual relationship between drug and kidney damage,IFN treatment was immediately discontinued.In three cases,we observed a complete and persistent remission of clinical and laboratory abnormalities after IFN withdrawal,while the patient who developed thrombotic microangiopathy,despite IFN withdrawal and complement-inhibitor therapy with eculizumab,showed persistent severe renal failure requiring dialysis.CONCLUSION This case series highlights the causal relationship between IFN treatment and different types of renal involvement and enables us to delineate several peculiarities of this association.
