Abstract

Background: Diabetes mellitus (DM)-associated chronic kidney disease (diabetic renal disease) became the predominant etiology of the end-stage renal disease (ESRD) in the western countries and shows the same trend in the developing countries. Early mortality (EM) after the dialysis initiation, defined as death of all causes within the first 3 months after initiation of renal replacement therapy (RRT), is of concern especially for the high-risk renal patients including diabetics. The goal of the present study was to identify demographic and clinical risk factors associated with EM in a retrospective cohort of Romanian DM patients initiated on dialysis.

Methods: A retrospective case-control study was designed. Clinical recordings from all patients initiated on hemodialysis (HD) or peritoneal dialysis between January 1996 and December 2005 in the Dialysis Center of NIDNMD Paulescu, Bucharest, were collected and analyzed. Patients were classified accordingly in two groups: those who displayed EM formed the "cases" group, while the others were included in the "controls" group. Both univariate (subgroup analysis) and multivariate analyses (logistic regression, Cox regression) were used to analyze the impact of risk factors on EM outcome.

Results: Data from 788 patients were included in the analysis. The factors significantly associated with EM in the univariate analysis were female gender, late initiation (LI) of dialysis, old age and HD used as the first/only method. Applying the multivariate analysis, only the use of HD (OR = 4.20, p < 0.0001) and the LI of dialysis (p < 0.0001; 95 % CI 1.36-2.30) were associated with EM, while female gender showed only a trend to a higher EM (OR = 1.29, p = 0.052).

Conclusions: Hemodialysis used as a first/single method for RRT and the LI of dialysis were independent predictors of EM in our ESRD diabetic patients. A possible explanation for the first factor could be our specific center procedure, which allows only the HD as rescue therapy method for the most severe cases, managed in the intensive care unit.
