| Summary: | Chronic kidney disease is defined as progressive kidney dysfunction. The levels of various cytokines increase in hemodialysis (HD) patients. High levels of interleukins (ILs) and presence of metabolic acidosis are described as independent risk factors for morbidity and mortality in these patients. This study was designed to evaluate the relationship between IL-6 and IL-10 and serum bicarbonate and metabolic acidosis in HD patients. In this analytical crosssectional study, patients referred to the HD units of Loghman Hakim and Shahid Ashrafi Esfahani Hospitals were randomly selected. Demographic and laboratory data, such as albumin, creatinine, calcium, phosphorus, parathormone, C-reactive protein, complete blood count, ferritin, ILs-6 and -10, and arterial blood gas analysis, were recorded for each patient. The correlation between IL and serum bicarbonate and other variables were evaluated by SPSS software. The patients were compared for the presence of acidosis and positivity for IL. A total of 84 patients with a mean age of 60.98 years and mean body mass index of 24.86 kg/m[2] were evaluated (53% male and 57% female). The mean dialysis duration was 24.86 ± 3.98 months. Overall, 41.7% of the patients had diabetes mellitus and 36.9% of them had hypotension. The mean serum levels of IL-6 and IL-10 were 6.036 and 17.46 pg/ml, respectively. There was a significant correlation between IL-6 and IL-10 levels and serum bicarbonate and the incidence of metabolic acidosis (P <0.05). Based on the results, metabolic acidosis and bicarbonate could be considered prognostic factors to differentiate the increased levels of IL-6 and IL-10 and associated morbidity and mortality.
