A Dual Diagnosis of Myasthenia Gravis and Sjogren’s Syndrome in a Hispanic Patient: A Case-based Discussion of Clinical Findings, Therapeutic Implications, and Culturally Competent Care

The co-occurrence of myasthenia gravis (MG) and Sjogren's syndrome (SS) in a young, Hispanic, female patient underscores the diagnostic and therapeutic complexities inherent in autoimmune disorders. MG, a rare neuromuscular disorder characterized by autoantibodies impairing neuromuscular transmission, leads to variable muscle weakness and fatigue, notably affecting ocular and bulbar muscles. SS, an autoimmune condition with systemic manifestations, primarily affects secretory glands, resulting in symptoms such as xerostomia and xerophthalmia. Both conditions have higher prevalence rates in females, with MG particularly affecting young women under 40. Herein we present a case report and case-based discussion on diagnostic and management challenges of these two autoimmune conditions while highlighting issues specific to the Hispanic and underrepresented populations. Our goal is to highlight the intricate interplay between these two autoimmune pathologies to allow for more rapid recognition and reduce delay in diagnosis.
