“…This profile was different from that found by SOBREIRA et al (2001) 16 at the Iguatu Blood Center (CE), where most donors were 18 to 30 years old. The prevalence of donors older than 50 years in a historically endemic area region for Chagas disease is a reason for alert to the blood center, considering that the majority of contaminated individuals were in that age range, as control campaigns became actually significant in the 1970s.…”

SUMMARYThis study aimed at estimating the number of cases of non-negative serological reactions to Chagas disease in blood donors at the Blood Center of Botucatu, São Paulo, Brazil, from 2003 to 2010 and at relating them to their cities of origin. Five hundred and seventy-four non-negative results for Chagas disease were evaluated. Of these, 371 (64.8%) were reagent, and 203 (35.4%) were inconclusive. The prevalence of Chagas disease in blood donors was 0.05%. There were, on average, 72 cases/year, and a prevalence of males was observed (64.8%). Forty-three (7.49%) individuals were 18 to 30 years old; 92 (16.02%) were 31 to 40; 147 (25.61%) 41 to 50, and 292 (50.87%) were older than 50 years. It was observed that 29.3% of females with reagent serology were at their fertile age (18 and 45 years). The majority of donors were originally from cities in the southwestern and central regions of São Paulo, but individuals from other states contributed with 20%. The provenance of most donors was the city of Botucatu/SP, followed by the city of Taquarituba/SP. Therefore, the profile of donors at this blood center favors the occurrence of a larger number of non-negative serological reactions. Although there has been a significant reduction in the number of new cases/year for this disease, it is still a public-health problem, and results suggest the need for new epidemiological assessments in the studied region.

There is a paucity of publications on regional variations in seroprevalence of infectious diseases in blood donors within Brazilian states, so that suitable time trends can be derived for major demographic groups.A population study of blood donors in the southern state of Santa Catarina, Brazil, was conducted using all computerized records of the blood donors submitted to serologic screening in 2010. The subjects were predominantly male (57.8%), aged 18-25 years (33.5%), did not direct their donation to any specific recipient (55.6%), nor did they provide another blood donation in last 12 months (58.6%). The highest seroprevalence was observed for the hepatitis B markers (3.0% for anti-HBc and 0.2% for HBsAg), followed by those for syphilis (0, 08% VDRL), HIV-1 (0.06%), hepatitis C (0.05%), HTLV1/2 (0.01%) and Chagas disease (0.01%). The risk factors associated with higher seroprevalence were associated with the first time donation, being male and of older age. Large regional variations were observed, with the Far West region reaching 7% of anti-HBc and 0.5% of HBsAg positive, and the Midwest region showing 0.1% HIV-positive donors.Hepatits B markers of both lifetime and recent infection reached a high level among blood donor candidates in Santa Catarina in 2010 and remain the foremost serological deferral criterion, despite some evidence of the reduced transmission rate compared to the beginning of the decade. The seroprevalence of other sexually transmitted infections (HIV, syphilis) also persisted on a level too high for a blood donor population, implying even higher prevalence in the general population.
