  • ObjectiveAlthough juvenile‐onset proliferative lupus nephritis (PLN) leads to significant morbidity and mortality, there is no clinical trials–based evidence to support the treatment effectiveness of any therapy for juvenile‐onset PLN. Marginal structural models enable us to estimate treatment effectiveness using observational data while accounting for confounding by indication.MethodsWe used prospectively collected data to examine the effect of mycophenolate mofetil (MMF), compared to the use of other therapies, on the long‐term outcome of a juvenile‐onset PLN cohort (age at PLN onset <18 years). The major outcome variable was the estimated glomerular filtration rate (GFR) using the revised Schwartz formula. Confounding by indication was corrected for marginal structural model.ResultsA total of 172 subjects with juvenile‐onset PLN, with a mean followup duration of approximately 4 years, were included. Overall, MMF was superior to other therapies, with a relative effect estimate for MMF of 1.06, i.e., 6% better estimated GFR on average (95% confidence interval 0.7, 11.3), corrected for potential confounding by indication. We found that beginning in year 4 there was a significant improvement in estimated GFR in the patients who were treated with MMF versus other therapies. This improvement was maintained until the end of the study.ConclusionMMF was more beneficial than other therapies in improving/maintaining long‐term renal function in patients with juvenile‐onset PLN up to a maximum followup of 7 years. This finding is consistent with evidence from adult PLN clinical trials.
