Prevalência de infecção chagásica em doadores de sangue no estado de Pernambuco, Brasil

Abstract: Conhecida também por tripanossomíase humana, a doença de Chagas apresenta-se como uma infecção sistêmica de evolução crônica que tem por agente etiológico o protozoário Trypanosoma cruzi. A doença encontra-se espalhada por toda a América Latina, onde constitui um sério

“…The percentage of inconclusive reactions (35.4%) at the Botucatu Blood Center was lower than that found at the Uberaba Regional Blood Center (53% of the non-negative reactions) and at the Pernambuco Blood Center (60.30%) 9,10 . Co-infection with other diseases may lead to crossreactions as well as to the low specificity of the tests used.…”

“…It was also lower than that found by SILVA & SILVA (2010) at Hemominas, Patos de Minas (MG) Regional Office, where the estimated prevalence was 1.2% 14 . A study conducted by MELO et al (2009) 9 at the Pernambuco Blood Center (HEMOPE) from 2002 to 2007 on the non-negative serological reactions to Chagas disease found a prevalence rate of 0.17% of the total number of donations, with an annual mean of discarded bags of 127.5 this value higher than that found at the Blood Center of Botucatu (72 units/year). It is noteworthy that there are, on average, 46 new confirmed cases per year (reagent serology) and other 25 suspected cases (inconclusive reactions).…”

“…4 In 1988 Brazilian legislation started requiring blood donors to be registered and blood samples to be tested individually for infectious diseases with high sensitivity tests, 19,28 and in 1991 the Southern Cone Initiative (INCOSUR) was created by Brazil, Argentina, Chile, Paraguay, Uruguay and Bolivia, aiming to reduce and eliminate transfusion transmission through the strengthening of the blood banks and control of the donors (Table 1). 10,15,19 It has been argued that the high proportion of inconclusive reactions was caused mainly by the high percentage of first-time donors, and could also be related to the frequent changes in the brands of the screening tests, a result of the tendering rules to which public blood banks are subjected. 31 Ferreira-Silva 20 analysed the differences between commercial ELISA tests from two laboratories and showed that the sensitivity and specificity levels of tests from different manufacturers differed considerably.…”

“…10,30 As for the profile of the chagasic donor, Lima et al 2012 29 found a predominance of ChD in people aged 30 years or above, which had 5.5 (95%CI: 4.44; 6.93) times the odds of having the disease, compared to those less than 30 years old. Similarly, Melo et al 10 found significantly higher prevalence of ChD in donors aged above 30 years old.…”

“…Contudo, paralelamente à baixa prevalência de doadores chagásicos, vem chamando atenção a significativa proporção de doadores inaptos sorológicos em decorrência de sorologia inconclusiva. Estudos de prevalência evidenciaram 69,6% de inconclusão em São Paulo (SP),¹¹ 52% em Uberaba (MG), 5 e 74% nos Estados Unidos.¹² No atual estudo de Melo et al, 6 foram registrado 60,3% de índice de inconclusão, confirmando os estudos citados e chamando atenção para o seu significado e consequências.…”
