RESUMO
The reactivities of sera from chronic chagasic patients against the trypomastigote excreted-secreted antigens (TESA) of Trypanosoma cruzi strains with different biodemes were analyzed by TESA-blot and TESA-enzyme-linked immunosorbent assay (ELISA). Although both tests presented high sensitivity and specificity, TESA-ELISA is more appropriate for screening a larger number of samples.

In 1987, diabetes mellitus was mentioned in 492 death certificates of the population of the city of Recife, Brazil, 202 of them for males and 290 for females. Diabetes mellitus was the underlying cause of death according to 80 certificates for men and 290 for women, as a result of which premature death occurred in 16.2% of men and 11.1% of women. Multiple cause of death analysis showed that cardiovascular diseases were the most frequent underlying cause of death in individuals over 50 years of age and acute complications of diabetes mellitus in individuals under 50. Cerebrovascular diseases were the most frequent in the cardiovascular group, particularly in females. Arterial hypertension was the most frequent associated cause of death appearing in death certificates mentioning diabetes mellitus (not as the underlying cause of death), also more often in females. The acute complications of diabetes mellitus (keto-acidosis and coma) and peripheral circulatory disorders peculiar to this disease caused 23% and 30% of the deaths, respectively, in cases where diabetes mellitus was the underlying cause. Infectious and parasitic diseases were the most frequent associated causes of death according to those certificates which gave diabetes mellitus as the underlying cause.
