Abstract
Background: Hepatitis B virus-associated glomerulonephritis (HBV-GN) can occur in patients with negative HBV serological antigens. Little is known about the treatment of seronegative HBV-GN (sn HBV-GN). The aim of this prospective study was to evaluate the efficacy and safety of corticosteroids in the treatment of sn HBV-GN. Methods: Twenty-six patients with nephrotic syndrome induced by seronegative HBV-associated membranous nephropathy were enrolled. The patients were given methylprednisolone (0.8 mg/kg/day) for 12–24 weeks, tapered by a 2-mg reduction every 1–3 months. Patients were followed up for 6–36 months. Complete remission (CR) was defined as proteinuria Results: The effective remission (including CR and PR) rates of nephrotic syndrome were 23.1%, 61.5%, 73.1%, 76.2%, 90.5%, and 81.0%, respectively, after 1, 3, 6, 12, 24, and 36 months. Nineteen patients achieved effective remission after 11.68 ± 7.15 months. The level of serum albumin improved from 24.34 ± 6.71 g/L at baseline to 39.61 ± 7.45 g/L at the 36th month significantly. After treatment, the level of serum Cr was similar to the baseline. Only 2 patients relapsed. The primary adverse reaction was infection. None of the patients showed evidence of HBV replication. Conclusion: The long-term middle-dose corticosteroid therapy without antiviral drugs is effective and safe for membranous sn HBV-GN patients. For sn HBV-GN patients, the monitoring of HBV DNA and HBV markers in the serum is necessary during the corticosteroid monotherapy. Trial Registration: The Chinese Clinical Trial Registry (ChiCTR1900022518).Keywords
