Weight and Muscle Mass Loss Associated with Acute Disease Can Be Reversed with Appropriate Nutrition Therapy and Exercise in a Patient with Amyotrophic Lateral Sclerosis.

Nutritional interventions targeting weight loss are useful for the treatment of amyotrophic lateral sclerosis (ALS). However, the changes in body composition after nutritional intervention remain unclear. We herein present a patient with ALS who experienced an increased weight and muscle mass owing to nutritional therapy and physical exercise. An 86-year-old man presented with dysphagia and dysarthria. The patient was diagnosed with bulbar-type ALS. As weight loss progressed, a gastrostomy was performed. After 21 months of disease onset, gastrointestinal bleeding due to a bumper ulcer led to further weight loss (from 40.2 kg to 36.8 kg). The patient experienced difficulty walking and ingesting food orally. Although the total daily energy expenditure (TDEE) was estimated to be 1,122 kcal/day, an intake of 1,500 kcal/day beyond the calculated TDEE was administered. The patient continued to perform daily voluntary exercises in addition to his usual rehabilitation. After 5 months, his weight increased from 36.8 kg to 40.4 kg. Muscle mass increased from 25.1 kg to 30.1 kg, as measured using a multifrequency bioelectrical impedance device. Muscle strength improved from 8.5/10.0 kg to 15.0/18.0 kg in grip strength and from 15.2 kPa to 20.4 kPa in tongue pressure. The patient's physical and swallowing functions also improved. In patients with ALS, a decreased body weight and muscle mass due to acute disease may be improved by appropriate nutritional therapy and physical exercise.
