Change in immunosuppression produces response in refractory lupus nephritis

Posted on July 27, 2021

Most patients with refractory lupus nephritis (RLN) who change immunosuppression agents see a response to therapy, according to a study.

In this observational bidirectional study, 45 patients with RLN who either failed to improve within 3 months, did not achieve partial renal response (PR) at 6 months, or did not achieve complete renal response (CR) after 2 years of treatment, and were followed for at least 9 months were included.

The median (IQR) SLE duration was three years (2-6 years). Overall, 25 patients had proliferative LN (ISN/RPS class III/IV), with 9 having pure membranous LN (class V).

During a median follow-up period of 15 months, 28 patients had CR, 9 had PR, and 8 had no response to a switch in an immunosuppressive agent.

In more than half of patients there was a histological class transformation, confirmed via repeat renal biopsy with a mean (±SD) biopsy interval of 2 (±1) years.

Immunosuppressive agent used or use sequence did not result in different treatment outcomes or time to attain response.

Three patients died due to infection.
