Perfil sorológico dos doadores de sangue do município de Uruguaiana (RS) no ano de 2017

Abstract

Hemotherapy, both in Brazil and in the world, has been qualified in the development and application of new technologies aimed at reducing transfusion risks, mainly in terms of preventing the spread of infectious agents. In the case of blood banks, one of the ways to avoid transmission is thorough quality control of donated blood. Access

to information on seroprevalence is extremely important components for epidemiolog- ical surveillance of infectious diseases and can be used to analyze and propose strat- egies in health, involving prevention and care. The objective of this study was to verify

the serological positivity of the blood donors of the Municipality of Uruguaiana-RS in the year 2017. In the analyzed period, 1934 donors were considered eligible. Of these, 97.34% presented non-reactive serologies for all tests performed and 2.28% reactive for at least one of the evaluated parameters. Of the donors with positive serology,

53.34% were men and 46.66% were women. In relation to diseases, syphilis and Hep- atitis B had a prevalence of 0.70%, being 9 women and 9 men respectively. Hepatitis

C and Chagas disease, the results showed a reactivity of 0.30% and 0.25% respec- tively, with a predominance of women for Hepatitis C and men for Chagas' disease.

About HTLV and HIV, the results showed reactivity of 0.19% and 0.14% respectively, with no greater difference between genders. Regarding the age group of the donors, there was no difference in this year, since the serologies ranged from 16 to 54 years.

When comparing Uruguaiana with state and national data, the number of reactive se- rologies in Uruguaiana was below the state and national average, except for Chagas'

disease, where Uruguaiana is above the national average, but below the state aver- age. Such diseases can be contracted during the blood transfusion, therefore the need for analysis to propose strategies in health.
