Background Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength with a risk of adverse outcomes such as physical disability, poor quality of life and death. Uremic sarcopenia causes a high morbidity and mortality and consequently a high priority for muscle wasting prevention and treatment in these patients.
Objectives To assess sarcopenia (muscle state and power) in CKD patients with & without hemodialysis.
Methods In this study there were three studied groups: Group I: 20 CKD patients on regular hemodialysis. Group II: 20 CKD patients on conservative treatment. Group III: 20 normal persons. After informed consent all patients recruited from dialysis unit, inpatient and outpatient clinics of Internal Medicine Department at Ain Shams University Hospital. Diabetic, patients with hemoglobin ≤10 g/dl, aged ≥50 years or have chronic diseases that may cause secondary sarcopenia had been excluded from the study. All subjected to full medical history and clinical examination. The muscle power assessed using the hand grip dynamometer1, physical performance through using 4 Meter Walk Gait Speed Test2. CBC, serum creatinine, BUN, serum electrolytes & PTH. Dual-energy X-ray absorptiometry (DEXA)3 was used to assess bone loss and total body mass loss (lean mass, fat mass, BMD). Assessment of nutritional status by using subjective global assessment (SGA) score4.
Results There is high significant positive correlation between age and 4 meter walk test. Group I & II had a higher mean time of 4 meter walk test & weaker hand grip strength compared to the control. There is positive correlation between 4 meter walk test and SGA score & clinical symptoms of sarcopenia (asthenia, easy fatigability, weakness & muscle cramps), negative correlation with hand grip strength. Also there is positive correlation between hand grip strength with lean mass & BMD and negative correlation with clinical symptoms of sarcopenia, fat mass & SGA score. There is negative correlation between SGA score with lean mass, fat mass & BMD. 4 meter walk test is the most specific & sensitive test to diagnose sarcopenia in CKD patients.
Conclusions Sarcopenia was present in CKD patients with hemodialysis more than without hemodialysis than normal people. Asthenia, weakness, easy fatigability & cramps are warning symptoms for sarcopenia. 4 meter walk test was the most specific & sensitive test to assess sarcopenia in CKD patients.
