Factores de riesgo para la transmisión de la hepatitis C en hemodiálisis

the hepatitis c virus infection (hcv) is a common complication in patients with chronic renal failure undergoing periodical hemodialysis. a retrospective cohort analytical study was conducted in the hemodialysis unit to analyze the incidence of hcv infection among the patients treated by hemodialysis and its casual association with different variables, such as: time of hemodialysis (thd), number of transfusions, base disease, sex and color of the skin. the period of study was divided into 5 strata. a sample of 53 patients was analyzed. they were determined anti-hcv by elisa of second and third generation every six months to diagnose the infection. it was found that the global incidence rate was 1.01 per 100 months/patients. males showed a higher relative risk (rr) with 5.2 (with statistical significance). the subjects that suffered from glomerulopathies had the greatest number of cases infected for an incidence density of 1.6 per 100 months/patients. the white patients prevailed and the thd showed an rr of 1.3. blood transfusions represented the most remarkable evidence as a risk factor with an rr of 4.3, and a statistically significant p < 0.05. it was concluded that the risk factors with the highest force of association with the hcv infection in hemodialysis patients are: the amount of blood transfusions, the presence of glomerulopathies and the male sex.
