Disease-Modifying Antirheumatic Drug Therapy of Inflammatory Rheumatic Diseases in End-Stage Kidney Disease.

Background: Inflammatory rheumatic diseases regularly require the use of disease-modifying antirheumatic drugs (DMARDs). The use of DMARDs in patients with end-stage chronic kidney disease (CKD stage 5D) is particularly challenging due to the lack of systematic studies available for this patient population. This narrative review aimed to address the aspect of DMARD therapy in CKD 5D.

Summary: The current article is a narrative review. References were sourced from the following databases: PubMed, Web of Science, Cochrane Library, and Scopus. The search period spanned from 1975 to 2024. There is a notable lack of systematic data on this topic. The available literature was reviewed to provide insights, despite the limited availability of comprehensive studies. Individuals with terminal kidney disease can presumably be safely treated with leflunomide, mycophenolic acid, sulfasalazine, azathioprine, belimumab, and anti-CD20. For all other substances, there are either significant restrictions, insufficient data, or inadequate experience.

Key messages: Some conventional and biologic DMARDs are available for the management of inflammatory rheumatic diseases in CKD stage 5D. It is essential to consider the limitations on kidney function, as they can significantly affect the pharmacokinetics of medications. Consequently, slightly more frequent checkups are recommended when using the defined preparations.
