We evaluated the way in which duration of hemodialysis treatment affects nutritional status in 96 @entity454 @entity1 . According to the length of previous hemodialysis treatment @entity1 were divided into the groups: onset hemodialysis (ON- @entity2033 ), early-stage hemodialysis (ES- @entity2033 , 1-8 months), mid-stage hemodialysis (MS- @entity2033 , 9-69 months), and @entity5 ( @entity5 , 70-207 months). Nutritional status was assessed by laboratory data (serum proteins, total lymphocyte count), intradermal skin antigen testing, anthropometric measurements (body mass index [BMI], infrared interactance), and records of food intake. ON- @entity2033 @entity1 on a low-protein diet exhibited abnormally low values for serum total protein, albumin, @entity69 , and total lymphocyte count and a high prevalence of anergy to skin antigens (69%). In the ES- @entity2033 and MS- @entity2033 groups values for serum proteins and total lymphocyte count were in the normal range and significantly higher than in ON- @entity2033 @entity1 . In addition, a lower proportion of cutaneous anergy was observed (50% and 27%, respectively). Long-term hemodialysis therapy for 6-17 years ( @entity5 ) was associated with normal levels for all measured serum proteins. Subnormal levels of total lymphocyte count, significantly lower than in MS- @entity2033 @entity1 , were associated with an increase in anergy to skin antigens (46%). Serum prealbumin, complement C3c, BMI, body fat, and lean body mass exhibited normal values in all @entity1 and showed no differences between groups. These results indicate that diminished visceral protein stores, @entity2905 , and anergy to skin antigens are widespread in undialyzed uremic @entity1 with @entity454 but become uncommon after the initiation of regular hemodialysis therapy.(ABSTRACT TRUNCATED AT 250 WORDS)
