Five-Month Trial of Whole-Food Plant-Based Diet in a Patient With Coexisting Myasthenia Gravis and Lambert-Eaton Myasthenic Syndrome.

Introduction: Nutritional intervention, such as a whole-food plant-based (WFPB) diet, is suggested to improve symptoms of autoimmune disorders. Its effects on neuromuscular junction (NMJ) diseases are less known. Case Description: A 56-year-old female with a combined myasthenia gravis and Lambert-Eaton myasthenic syndrome presented with persistent musculoskeletal weakness and pain, fatigue, and diminished concentration. Methods: A WFPB diet was implemented for 5 months in this case study. Functionality, biometrics, and quality of life were assessed at regular intervals via blood work, vital signs, and patient surveys. Results: After 10 weeks, 2 medications were de-prescribed due to improvement in blood glucose levels and blood pressure readings. Neuromuscular symptoms lessened as measured by the Myasthenia Gravis Illness Index. Weight loss of 18.7 pounds was achieved. No deterioration in physical activity was reported throughout the 5-month trial of WFPB diet. Discussion: Our results have implications that an individualized dietary strategy may be considered as one component of management of NMJ diseases. The effects of WFPB diet on NMJ diseases remain inconclusive.
