More hostile dyslipidaemia in chronic kidney disease patients on maintenance haemodialysis than on conservative management.

Objective: To study the pattern of dyslipidaemia in patients with stage-V chronic kidney disease on conservative management and those on maintenance haemodialysis.
Methods: This comparative observational study was conducted at the Jinnah Postgraduate Medical Centre, Karachi, from February to July, 2008, and comprised stage-V chronic kidney disease patients. The patients were divided in two groups. Those who were on conservative management were placed in Group A, and those who were on maintenance haemodialysis were in Group B. Serum total lipid, cholesterol, triglycerides and high-density lipoprotein for both groups were assayed on chemical analyser and low-density lipoprotein was calculated by Friedwald equation. SPSS 17 was used for data analysis.
Results: Of the 120 patients, there were 60(50%) in each group. The mean age of patients in Group A was 46.33±14.56 years and in Group B was 43.4±14.1years. Of all, 64(53.3%) were men and 56(46.7%) were women. Mean systolic and diastolic blood pressure was 134±19.58mmHg and 83.6±14.14mmHg in Group A and 129±19.7mmHg and 79.7±12.1mmHg in Group B. Mean serum total lipid was significantly higher (p<0.01) whereas mean serum cholesterol was significantly lower (p<0.01) in Group B. Comparison of mean serum triglycerides between the groups was also statistically significant (p<0.01) and was high in Group B. Mean serum high-density lipoprotein was lower in Group B (p<0.01). The difference between serum low-density lipoprotein levels was statistically insignificant between the groups (p=0.11).
Conclusions: Pattern of dyslipidaemia in patients on maintenance haemodialysis was more hostile than those on conservative management, and posed increased risk of coronary heart disease.
