Sažetak

Background: Depression is a common psychiatric problem in patients undergoing dialysis. Several studies have been performed
to validate the association between depression and inflammation in haemodialysis patients. The levels of proinflammatory cytokines
are increased in chronic renal failure patients, as in depression. The objective of this study was to compare the incidence of
depression in the patients on dialysis (on hemodialysis /HD/ and on continuous ambulatory peritoneal dialysis /CAPD/), and a
relationship between depression and the presence of inflammation.
Subjects and methods: 88 patients (52 on HD and 36 on CAPD) were enrolled in this study.
Depressive symptoms were measured with the Beck Depression Inventory (BDI). The BDI is a 21-item self-report instrument, and
the elevated symptoms of depression were defined as a BDI score ≥16. HD patients were treated with high-flux polysulphone
biocompatible dialyzers and CAPD patients were treated with usual dwell time (4-6 hours during the day and 8–10 hours at night).
The presence of an inflammatory state was assesded by determinations of plasma interleukin-6 (IL-6) levels.
Results: Depression (BDI ≥ 16) was present in 28.4% of dialysis patients, 35% of patients on hemodialysis (HD) and 18.1% of
patients on continous ambulatory peritoneal dialysis (CAPD). The BDI score was significantly lower in CAPD patients comparing to
HD patients, as well as the levels of albumin, C-reactive protein (CRP) and interleukin-6 (IL-6). IL-6 serum levels were similar in
patients with depression and patients without depression in the whole group, as in HD patients. In CAPD patients without depression
IL-6 levels were significantly lower.
Conclusions: The prevalence of depression was higher in HD comparing to CAPD patients. Although IL-6 level was higher in
HD compared to CAPD patients, the relationship between depression and presence of inflammation parametars were observed in
CAPD, but not in HD patients.
