The Study Evaluating the Improvement of Nutritional Status and Frailty With Silkworm Pupa Powder Among Patients With Motor Neuron Disease

研究简介（原文）

Motor Neuron Disease (MND) is the result of dysfunction of the upper motor neurons in the precentral gyrus of the frontal lobe or the lower motor neurons in the ventral horn of the spinal cord. Amyotrophic lateral sclerosis (ALS) is the most common, disabling, and fatal motor neuron disease in adults. Sarcopenia is a syndrome characterized by progressive loss of skeletal muscle mass, accompanied by a reduction in muscle strength and (or) function, and it is an important feature of MND. Aging is an objective and inevitable process that involves the gradual degeneration and loss of physiological functions in various tissues, organs, and cells. With the continuous accumulation of various injuries, the body eventually exhibits signs of frailty such as fatigue, reduced muscle strength, and weight loss. Data from adult ALS patients indicate that 58% of patients are at risk of frailty. Silkworm pupa contains high-quality animal protein and has a wide range of activities in antioxidant, antitumor, antibacterial, and immune enhancement, making it highly nutritious and medicinally valuable. Silkworm pupa extracts can enhance grip strength in older adults with relatively low skeletal muscle mass. As a natural food ingredient with high safety, the value of silkworm pupa in ALS patients lacks corresponding research, which limits its further application in clinical practice. This study aims to select ALS patients as the research subjects and use a randomized, controlled, double-blind prospective study design to evaluate the effectiveness of silkworm pupa tablets in improving sarcopenia, frailty, and quality of life in ALS patients. The study strives to improve the frailty condition of ALS patients and enhance their quality of life by supplementing nutrition, thereby providing new strategies for comprehensive intervention and management of ALS patients.
