Hemodialysis duration impairs food intake and nutritional parameters in chronic kidney disease patients.

Introduction: The aim of this study was to evaluate the effect of hemodialysis (HD) duration on food intake and nutritional markers in patients with chronic kidney disease (CKD).

Methods: Twenty CKD patients received maintenance HD over a 9-year period. At the beginning of the study (T0) and at 3-year intervals (T1, T2, and T3) during the 9-year follow-up, a nutritional survey using the 24-h recall and record method was repeated for 4 days, and the blood samples were drawn.

Long term hemodialysis aggravates lipolytic activity reduction and very low density, low density lipoproteins composition in chronic renal failure patients.

Background: Dyslipidemia, particularly hypertriglyceridemia is common in uremia, and represents an independent risk factor for atherosclerosis.

Methods: To investigate the effects of hemodialysis (HD) duration on very low density lipoprotein (VLDL) and low density lipoprotein (LDL) compositions and lipopolytic activities, 20 patients on 5 to 7 years hemodialysis were followed-up during 9 years. Blood samples were drawn at T0 (beginning of the study), T1 (3 years after initiating study), T2 (6 years after initiating study) and T3 (9 years after initiating study).

Effect of long-term hemodialysis on plasma lecithin: cholesterol acyltransferase activity and the amounts and compositions of HDL2 and HDL3 in hemodialysis-treated patients with chronic renal failure: a 9-year longitudinal study.

Background: Atherosclerosis was correlated with hemodialysis duration (HD) in chronic renal failure (CRF) patients. Dyslipidemias were identified as atherogenic risk factors.

Material/methods: To investigate variations in HDL2 and HDL3 composition and lecithin: cholesterol acyltransferase (LCAT) activity as functions of HD, 20 CRF patients were selected for maintenance hemodialysis during the 9 years from April 1, 1991 to March 31, 2000.

Plasma lipoprotein lipase, hepatic lipase activities, VLDL, LDL compositions at different times of hemodialysis.

The effects of hemodialysis duration (HD) on lipoprotein lipase (LPL) and hepatic lipase (HL) activities and very low density lipoprotein (VLDL), low density lipoproteins (LDL) amounts and compositions were investigated in 58 patients, divided according to HD: GI: under 1 year, GII: 1-5 years, GIII: 5-13 years. HL and LPL activities were reduced in GIII versus GI (P<0.01) and 47% of GIII patients had negligible HL activity.

Changes in plasma lecithin: cholesterol acyltransferase activity, HDL(2), HDL(3) amounts and compositions in patients with chronic renal failure after different times of hemodialysis.

The aim of this study was to investigate the effect of hemodialysis duration on HDL(2) and HDL(3) compositions and lecithin:cholesterol acyltransferase (LCAT) activity in 58 patients on acetate hemodialysis using cuprophane membrane, after different periods of dialysis. Patients were divided into three groups-GI <1 year, GII 1-5 years, GIII 5-13 years of dialysis and were compared with 22 controls. Increase by 34% of triacylglycerols (TG) was noted in GI and by 36% in GII versus GI.
