Prevalence of infectious diseases in patients with end stage renal disease in Gorgan City in Iran

Background: The mortality rate of sepsis and pneumonia is higher in end-stage renal disease (ESRD) patients than in the general population. Bacterial infections are the most common cause of hospitalization in dialysis patients and the most common source of bacteremia is vascular access in these patients. The aim of this study was to determine the prevalence of infectious causes of hospitalization in patients with endstage renal failure in Gorgan. Methods: This cross-sectional study was performed on patients with ESRD who were admitted to the 5 Azar Medical Education Center of Gorgan City during 2014 to 2016. Patients' information was collected through their clinical records and analyzed statistically. Results: The prevalence of infectious diseases in ESRD patients during the 3 years was 12.7, out of 100 hospitalized patients with ESRD and infectious causes, the most common type of infectious disease was catheter infection (43) and sepsis (18), urinary tract infection (11) and pneumonia (8) were the next. The most common infectious causes leading to hospitalization in men with the ESRD were catheter infection, sepsis, and pneumonia, respectively, and in women, catheter infection, sepsis, and urinary tract infection. The highest incidence of catheter infection was in the age group of 66-70 years (30.2), 71-75 (25.6), and above 71 years (25.6), respectively. The highest incidence of sepsis occurred in the age group of 75-71 years (38.9) and also the highest incidence of urinary tract infections in the age group of less than 65 years. Age (P=0.003), sex (P=0.01), duration of disease (P=0.009), addiction (P=0.01), and diabetes (P=0.01) were the most common risk factors for infectious diseases in patients with ESRD. Conclusion: The results of this study showed that catheter infection is the most common cause of infection in patients with end-stage renal disease (ESRD). Therefore, avoiding multiple vascular manipulations, disinfection of the catheter, timely replacement, and training of dialysis staff are effective in reducing catheter infections. © 2020 Tehran University of Medical Sciences.
