Serum albumin level is not only one of the protein-energy wasting criteria but also a powerful marker of mortality in patients on haemodialysis (HD) treatment. The study aimed to assess the effect of a protein-enriched snack given during HD treatment on serum albumin level.This prospective, single-centre, observational, non-randomized 16-month study was sub-divided into four 4-month periods. Patients on hemodialysis for more than three months and receiving a regular standard snack (8.8 g of protein) during the HD session were included and assigned during four four-month periods to receive either the standard snack or a protein-enriched snack (28.7 g). Patients were not selected based on nutritional criteria.Sixty-six patients completed the study. Serum albumin levels significantly increased, from 3.43 ± 0.28 g/dl in the first period (standard snack) to 3.62 ± 0.32 g/dl (p
