Real-world discontinuation of immunosuppressive therapy after proliferative lupus nephritis: the overlooked impact of non-adherence (MASSILUP-WIN)

Lupus Sci MedPublished retrospective inception cohort

Authors' conclusion

In routine clinical practice, more than half of patients with pLN discontinue IST, and a substantial proportion of discontinuations occur outside a planned withdrawal strategy. Non-adherence was the factor most strongly associated with renal relapse, identifying a high-risk subgroup often excluded from treatment withdrawal studies. These findings highlight the importance of therapeutic alliance and patient education when considering IST discontinuation in LN.
