Abstract:
Background: Rituximab has become one of the first-line therapies for the treatment of moderate and high-risk primary membranous nephropathy (pMN). We retrospectively reviewed 95 patients with pMN who received rituximab therapy and focused on the therapeutic effects and safety of this therapy in a Chinese cohort. Methods: Ninety-five consecutive patients with pMN diagnosed by kidney biopsy received rituximab and were followed up for & gt;6 months. Four weekly doses of rituximab (375 mg/m 2 ) was adopted as the initial administration. Repeated single infusions were administrated to maintain B cell depletion levels of & lt;5 cells/mL. Results: A total of 91 patients completed rituximab therapy with the total dose of 2.4 (2.0, 3.0) g; 64/78 (82.1%) patients achieved anti-PLA2R antibody depletion in 6.0 (1.0, 12.0) months; 53/91 (58.2%) patients achieved clinical remission in 12.0 (6.0, 24.0) months, including complete remission in 18.7% of patients and partial remission in 39.6% of patients. Multivariate logistic regression analysis showed that severe proteinuria (OR = 1.22, P = 0.006) and the persistent positivity of anti-PLA2R antibodies (OR = 9.00, P = 0.002) were independent risk factors for no-remission. The remission rate of rituximab as an initial therapy was higher than rituximab as an alternative therapy (73.1 vs. 52.3%, P = 0.038). Lastly, 45 adverse events occurred in 37 patients, but only one patient withdrew from treatment due to severe pulmonary infection. Conclusion: Rituximab is a safe and effective treatment option for Chinese patients with pMN, especially as an initial therapy.
