title: Study of effect of optimization of dialysis and protein intake on neuromuscular function in patients under maintenance hemodialysis treatment.
abstract: This study was carried out on 22 patients on maintenance hemodialysis. Among them, 20 patients were males and 2 were females, their age ranged from 12 to 50 years. Initially, the patients were assessed clinically and by laboratory investigations and their dialysis was assessed by studying their urea kinetic modeling following the nomographic approach for calculating their Kt/V values. Their nutrition was assessed by measuring skin folds, midarm circumference, laboratory parameters and by calculating the normalized protein catabolic rate (nPCR). Also their neuromuscular functions were assessed by clinical examination and neurophysiologic study. Dialysis dose was readjusted to achieve a target Kt/V value of 1.3 for patients on 3 times weekly dialysis and 1.6 for patients on twice weekly dialysis. Also, their nutrition was reviewed to achieve nPCR 1.2 g/kg/day and caloric intake 30-40 kcal/kg/day through diet manipulation and support. The patients were assessed finally after 3 months on targeted dialysis and nutrition by thorough clinical, laboratory and neuromuscular assessment. Analysis of neurophysiologic data showed significant improvement in electromyography. Furthermore, fatigue test showed significant (p = 0.002) decreases in muscle fatigue after optimization of dialysis dose and patients' nutrition. From this study, we may conclude that in dialysis patients, even when asymptomatic and clinically stable, neurologic deficits do exist and using area kinetic modeling to improve dialysis and patients' nutrition is valuable in improving their neuromuscular functions.
