Abstract

OBJECTIVE

To identify HTLV-II revalence in blood donors at the Blood Center Net of Ceará (Hemorrede do Ceará - HEMOCE) and epidemiological aspects of positive cases.

METHODS

Cases considered positive were surveyed from data bases through the immunoenzymatic method ELISA and confirmed by Western Blot from 2001 to 2008. In this period, 679,610 blood samples from voluntary donors were tested.

RESULTS

From all donors, 164 samples were actually positive in both tests; of these, 33 (20.1%) were typed as HTLV-II, showing a prevalence of 0.006%. In positive cases, a mean age 28.2 years, and a predominantly male gender (54.5%) were observed, the race was mixed in 78.8%, most donors had Fortaleza as hometown (72.7%), with 51.5% being married/consensual union, and 33.3% reported to have completed high school education.

CONCLUSION

Although HTLV-II infection is low, its presence is universal, being similar in males and females mostly in urban centers. The need of preventive measures as a way of avoiding infection spread is stressed.

摘要

目的

确定在塞阿拉血液中心网络（塞阿拉血液库 - HEMOCE）献血者中HTLV-II的流行率以及阳性病例的流行病学特征。

方法

通过酶联免疫吸附测定法（ELISA）从数据库中调查被认为呈阳性的病例，并于2001年至2008年通过蛋白质印迹法进行确认。在此期间，对679,610份来自自愿献血者的血样进行了检测。

结果

在所有献血者中，有164份样本在两项检测中均呈阳性；其中，33份（20.1%）被分型为HTLV-II，流行率为0.006%。在阳性病例中，观察到平均年龄为28.2岁，男性占主导（54.5%），78.8%为混血种族，大多数献血者的家乡是福塔雷萨（72.7%），51.5%已婚/有事实婚姻关系，33.3%报告完成了高中学业。
