Abstract | RATIONALE: As suggested by the 2012 KDIGO guidelines, persistent elevation of serum creatinine > 3.5 mg/dl (> 309 μmol/l) (or an estimated glomerular filtration rate < 30 ml/min per 1.73 m is one of contradictions for the use of immunosuppressive therapy in membranous nephropathy. PATIENT CONCERNS: DIAGNOSES: The patient received repeated renal biopsy, comfirming the diagnosis of membranous nephropathy with progressive glomerular and tubulointerstitial scarring. INTERVENTIONS: He was treated with successfully four times with lose-dose (180 mg/m every 2-3 months) rituximab (RTX) depending on his B cell counts, aiming to remain at 0-5 cells/μl. OUTCOMES: The patient was followed-up for almost 6 years. He achieved a partial remission at 11 months and a complete remission of the nephritic range of proteinuria at 34 months following infusion of RTX. RTX was well tolerated and the patient's renal function improved. He had no edema and his dosage of corticosteroids could be discontinued. LESSONS: This case strongly suggested that rituximab has promising therapeutic significance, even in patients progressing to CKD4.
