Effectiveness and Safety of Rehabilitation for Pediatric Patients with Nephrotic Syndrome in the Acute Phase: A Case Study
Overview
Affiliations
Background: Exercise therapy for patients with pediatric nephrotic syndrome is necessary to improve physical function to maintain the patient's activities of daily life and school life while managing the risk of relapse; however, few studies have examined exercise therapy in the acute phase of the syndrome. This case study aimed to evaluate the efficacy and safety of exercise therapy in a patient with acute pediatric nephrotic syndrome being treated with steroids.
Case: The patient was a 10-year-old boy diagnosed with primary nephrotic syndrome. Prednisolone (50 mg) was started on the 3rd day of hospitalization. Exercise therapy (moderate-intensity, 40 min, five times a week) was started on the 15th day. The urine protein/creatinine ratio from the 15th day (at the start of rehabilitation) to discharge decreased from 1.1 to 0.4, with no recurrence of nephrotic syndrome. At the initial, middle, and final evaluations, respectively, the grip strength was 10.1, 8.9, and 8.3 kg; the knee extension strength was 0.38, 0.46, and 0.45 kgf/kg; the sit-up test results were 18, 18, and 15 times; the side-step test results were 34, 36, and 31 times; the sit-and-reach test results were 22.9, 24.5, and 23.8 cm; and the 6-min walk test results were 420, 490, and 520 m. Leg muscle strength and exercise tolerance improved, but upper limb strength, trunk muscle strength, and agility decreased.
Discussion: Moderate-intensity exercises may be effective and safe for pediatric patients with nephrotic syndrome in the acute phase. Exercise therapy may be beneficial to improve physical function and prevent decline during hospitalization in pediatric nephrotic syndrome patients.
