Combating protein energy wasting in end stage kidney disease: role of exogenous proteolytic enzyme as an adjuvant to dietary protein

Vishal Singh

Abstract


Background: Despite interventions, the prevalence of protein energy wasting in patients on dialysis continues to be unacceptably high. The objective of the study is to evaluate the efficacy of exogenous proteolytic enzyme Aminace 70000 (Hemoglobin Tyrosine Unit), as an adjuvant to dietary protein in improving the nutritional status.

Methods: This is a retrospective, real world, single centre, observational study, aimed at assessing the changes in key nutritional indices, over 6 months in patients with chronic kidney disease (CKD) initiated on continuous ambulatory peritoneal dialysis (CAPD). The intervention included addition of egg protein and use of an exogenous proteolytic enzyme. Three cohorts were identified. Cohort 1, had access to a nephrologist and CAPD counsellor; Cohort 2, in addition had access to a dietician who emphasized the need for increase in dietary protein in form of 4-6 eggs a day; and cohort 3, were in addition given an exogenous proteolytic enzyme with the major protein meal.

Results: The absolute fall in serum albumin at 6 months for the cohort 1, 2 and 3 is 0.48, 0.29 and 0.09 gm/dl respectively. Not only was the fall in serum albumin significantly less with the use of exogenous proteolytic enzyme, a higher proportion of patients were able to maintain or improve their serum albumin. The fall in midarm circumference was maximum in cohort 1 (2.08 cm) and least in cohort 3 (0.45 cm). This positive trend however, did not achieve statistical significance.

Conclusions: Use of exogenous proteolytic enzyme, when combined with egg protein, improves key nutritional indices in patients of CKD on CAPD.
