Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Assessing patient nutritional improvement using Third Lumbar Skeletal Muscle Index (L3-SMI).

    The nutritional index is evaluated using the Third Lumbar Skeletal Muscle Index (L3-SMI): A single cross-sectional image of L3 is obtained through CT scanning, and skeletal muscles in the image are identified and quantified using a HU threshold of -29 to 150. The total muscle area at this level is calculated using 3D Slicer software, and then divided by the square of the height (m\^2) to obtain the Third Lumbar Skeletal Muscle Index (L3-SMI).

    The 0th、 4th 、8th and 12th week after taking Silkworm Silkworm pupa powder.

  • The improvement of frailty in patients treated by the Frailty Phenotype (FP) Scale assessment.

    Frailty Phenotype Scale: The Frailty Phenotype (FP) Scale encompasses the following five clinical criteria: * Unintentional Weight Loss * Self-reported Fatigue * Decreased Physical Activity * Slowed Gait Speed * Weak Grip Strength Each criterion is scored as 1 point if met, with a total score ranging from 0 to 5. A score of 0 indicates robust health, a score of 1 to 2 indicates pre-frailty, and a score of 3 or higher indicates frailty. This scale is used to assess the frailty status of individuals, providing a separate outcome measure that focuses on the physical vulnerability and decreased resilience commonly associated with aging.

    The 0th、 4th 、8th and 12th week after taking Silkworm Silkworm pupa powder.

Secondary Outcomes (2)

  • Using the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) to assess patient functional status, thereby evaluating the improvement of neurological dysfunction.

    The 0th、 4th 、8th and 12th week after taking Silkworm Silkworm pupa powder.

  • Assess the respiratory function of patients with Amyotrophic Lateral Sclerosis undergoing treatment using the Oxygenation Index.

    The 0th、 4th 、8th and 12th week after taking Silkworm Silkworm pupa powder.

Study Arms (2)

Silkworm pupa powder

EXPERIMENTAL

The intervention in the trial involves providing silkworm pupa powder, twice a day, with two packets each time, to be taken before meals.The dose of gastrointestinal weak people was halved, twice a day, 1 pack each time, half an hour before breakfast and dinner.

Other: Chinese medicine - Silkworm pupa powder

Placebo

PLACEBO COMPARATOR

The intervention for the placebo group involves administering a placebo containing 0.5% of the active ingredient, twice daily, with two packets each time, taken before meals.The dose of gastrointestinal weak people was halved, twice a day, 1 pack each time, half an hour before breakfast and dinner.

Other: Ultra-low dose silkworm pupa powder
