Marcadores infecciosos asociados a factores demográficos en donantes de sangre peruanos

Introduction: The characteristics of blood donors may vary between hemotherapy centers and may be related to the seropositivity of infectious markers. Objective: To related the seropositivity of infectious markers with the demographic factors of Peruvian blood donors. Methods: Observational in the blood banks of the Hospital Nacional Cayetano Heredia and the Instituto Nacional Materno Perinatal during 2019. The population consisted of 11,936 donors who were screened for the seven infectious agents according to the National Hemotherapy and Blood Bank Program. Pearson's correlation test was used to determine the association between demographic variables and infectious markers. Results: Of the total, 8,449 (70.8%) were male and the age group from 35 to 55 years was the most frequent in both hospitals (~ 44.5%). Most donors came from the coast (4,944; 41.4 %), although at the Cayetano Heredia National Hospital, there were 734 (8.9%) from the jungle. Seropositivity was 507 (4.25%) donations, then most frequent was Hepatitis B virus core antigen, antibodies against human T-cell lymphotropic virus 1-2, and syphilis, with 51.2%, 16.8%, and 14.9%, respectively. Seropositivity of infectious markers was associated with demographic factors such as age, gender, and place of origin (p< 0.05). Conclusions: There is a relationship between demographic factors with the seropositivity of infectious markers in Peruvian donors.
