ABSTRACT

How to handle Western blot (WB) seroindeterminate individuals for Human T-lymphotropic Virus 1/2 (HTLV-1/2) constitutes a challenge for blood banks and fam ilies. We made a cross-sectional study of 191 enzyme linked immunoassay (EIA) reactive individuals from the hematological center (HEMOCE) of Fortaleza (Brazil), examining their serological (WB) and molecular (PCR) diagnosis, and demographic profiles, as well as a possible association of their condition with other infectious pathologies and risk factors. Ethical institutional approval and personal consent were obtained. Out of 191 EIA reactive individuals, 118 were WB seroindeterminate and 73 were seropositive for HTLV-1/2. In the PCR analysis of 41 WB seroindeterminate individuals, 9 (22 percent) were positive and 32 (78 percent) were negative for HTLV-1/2. The demographic analysis indicated a trend towards a predominance of males among the seroindeterminate individuals and females in the seropositive ones. The seroindeterminate individuals were younger than the seropositive ones. We did not find any association of these conditions with syphilis, Chagas disease or HIV or hepatitis, and with risk factors such as breast-feeding, blood transfusion, STD (syphilis) and IDU

ABSTRACT

A determinaçäo da atividade da colinesterase sérica nos indivíduos que aplicam praguicidas organofosforados e carbamatos se constitui num teste confiável de intoxicaçäo por esses inseticidas. Inibidores reversíveis das colinesterases estäo sendo usados, atualmente, no tratamento clínico da demência senil, tipo Alzheimer. Seus níveis de atividade säo usados, atualmente, no tratamento clínico da demência senil, tipo Alzheimer. Seus níveis de atividade säo usados na monitorizaçäo desse tratamento e na indicaçäo do grau de inibiçäo enzimática no cérebro e outros tecidos. Certos paciente, portadores de variantes genéticas isoenzimáticas, quando submetidos à anestesia pelo halotane e enflurane ou drogas como a succinilcolina, podem apresentar depressöes respiratórias graves. Diante do exposto e, porque näo existe disponível no mercado especializado, nenhum kit de fabricaçäo nacional que permita a avaliçäo da colinesterase nos diversos líquidos biológicos, estamos propondo o ACE-KIT, como um conjunto de reagentes capaz de avaliar, de modo prático, simples e barato, a atividade dessas enzimas
