Rituximab Combined with Steroid and Tacrolimus Treats Proliferative Glomerulonephritis with Monoclonal IgG Deposits: A Case Report and Review of the Literature

Introduction: Due to the confounding heterogeneity, the therapeutic strategy for proliferative glomerulonephritis with monoclonal IgG deposits (PGNMID) remains to be defined. Case Representation: We report a 38-year-old man with recurrent swelling of the eyelids and lower limbs, undergoing rituximab combined with steroid and tacrolimus treatment, who achieved an improved renal outcome. Underlying solid malignant tumours were excluded from the diagnosis. Discussion: We treated patients with rituximab along with steroids and tacrolimus. Improvements in proteinuria and renal function were observed. We also reviewed the current literature to assess the efficacy of rituximab in the treatment of PGNMID. Conclusion: However, a larger pool of patients and a longer follow-up period are required to establish the role of rituximab and steroids in the treatment of PGNMID.
