Renal disease associated with multiple sclerosis: A narrative review

Abstract

Multiple sclerosis (MS) is a chronic autoimmune neurological disorder characterized by central nervous system demyelination, leading to various neurological impairments. While the primary focus of research and clinical management has centered on the neurological aspects of MS, emerging evidence suggests a complex interplay between MS and renal disease. This narrative review endeavors to elucidate the intriguing association between MS and renal disease, providing a comprehensive overview of the current knowledge on this topic. Our review begins by outlining the pathophysiology of MS and the diverse mechanisms contributing to its progression. We then delve into renal disease, categorizing the various types and their clinical presentations. This review focuses on exploring the intricate relationship between these seemingly distinct conditions. We analyze existing literature to uncover shared risk factors, potential pathophysiological links, and the impact of MS on renal function. Furthermore, we discuss the clinical presentation and diagnostic challenges in identifying renal disease in MS patients. Importantly, we examine available treatment options and their efficacy in managing renal complications in this unique patient population. The consequences of renal disease on the overall quality of life (QOL) for individuals living with MS are also examined, shedding light on the multifaceted burden of these coexisting conditions.
