ABSTRACT

O objetivo deste estudo foi analisar parâmetros sorológicos e virológicos em hemofílicos no Estado da Bahia. O anti-VHC foi investigado por ELISA em uma coorte de 268 hemofílicos A/B sob acompanhamento em uma unidade de referência do Estado da Bahia. A viremia do VHC e genótipos foram determinados em um subgrupo de 66 hemofílicos soropositivos para o anti-VHC. A soroprevalência do anti-VHC entre os hemofílicos foi de 42,2% (IC 95% 36,5-48,1) e foi associada significativamente (p<0,05) a idade >10 anos, presenca de anticorpos antifator VIII/IX e outros marcadores sorológicos de infeccão. Nenhum dos hemofílicos com idade inferior a 5 anos foram anti-VHC positivos. A viremia foi detectada em 77,3% (51/66), sendo o genótipo 1 do VHC (74%) o mais prevalente, seguido pelos genótipos 3 (22%) e 2 (4%). Nossos resultados indicam que a prevalência do VHC é ainda alta entre os hemofílicos, muito embora a transmissão não tenha sido observada entre os menores de 5 anos.

ABSTRACT

Patients with chronic hepatitis C can have variable clinical progression. Hepatic histological alterations appear to be milder in asymptomatic subjects who have persistently normal ALT levels. AIMS: To evaluate the severity of histological liver alterations in blood donors with normal and elevated ALT levels. METHODS: We evaluated volunteer blood donors from the main blood bank of the city of Salvador-Brazil. Those who were anti-HCV positive were invited to participate in the study. Serum ALT and AST levels were measured at two time points, two months apart. Donors were divided into two groups: group I, individuals with ALT > 1.5 times the upper limit of normal in at least one time point and group II, individuals with normal or near normal ALT, at both time points RESULTS: We evaluated 30,232 blood donors and 528 (1.7 percent) of them were anti-HCV positive. Eighty-two attended our service and HCV infection was confirmed in 66 individuals. Male gender predominated in both groups; the mean age was 36 for group I, and 33 for group II. Tattoos and intravenous illicit drug use were frequently-encountered risk factors. Liver biopsy was done in 43 subjects. Among donors with elevated ALT, two (10 percent) had minimum alterations, while in group II normal liver or minimum alterations were observed in six (26 percent) subjects. Chronic hepatitis or cirrhosis was encountered in 35 (81 percent) individuals: three (15 percent) and five (21 percent) subjects had chronic hepatitis without inflammatory activity, 10 (50 percent) and 11 (48 percent) had minimum to moderate activity and five (25 percent) and one (4.3 percent) had cirrhosis, in groups I and II, respectively (P was not significant). CONCLUSIONS: The prevalence of anti-HCV among this population of volunteer blood donors was 1.7 percent, and these subjects had few liver histological alterations or chronic hepatitis and cirrhosis. Liver injury severity was significant in patients with elevated ALT, however subjects with normal levels may also present chronic hepatitis and cirrhosis.

ABSTRACT

Helicobacter pylori plays an important role in the etiology of peptic ulcer disease. Its prevalence appears to be higher in developing countries. We evaluated the seroprevalence of H. pylori and risk factors associated with infection in voluntary blood donors who attended the main blood center of the city of Salvador, Brazil. The subjects responded to an epidemiological questionnaire, with information about sex, age, race, lifestyle, social-economic level indicators, and residence and hygiene conditions. Anti-H. pylori antibody was determined by ELISA (Cobas Core, Roche). Three hundred and seven subjects were included in the study. Anti-H. pylori antibody results were indeterminate in 33 individuals (10.8 percent), who were excluded from analysis. Among the remaining 274 subjects, 187 (68.2 percent) were anti-H. pylori positive. Based on multivariate logistic regression analysis three variables were found to be significantly associated with a higher prevalence of H. pylori infection: absence of plumbing in the residence during childhood, a history of rainwater invading the dwelling during childhood, and low ingestion of milk.

ABSTRACT

Estudo restrospectivo de 2.464 exames retossigmoidoscópicos realizados no Hospital Universitário da Universidade Federal de Sergipe, no Hospital governador Joäo Alves Filho e em Clínicas Particulares de Aracaju - sergipe, no período compreendido entre Janeiro de 1991 a dezembro de 1999. em 442 exames foram observados processos inflamatórios, dos quais houve comprovaçäo de retocolite esquistossomótica em 55 casos. Foram analisadas variáveis como idade, sexo, manifestações clínicas procedência, localizaçäo das alterações, patologias associadas e impressäo dianóstica ao exame endoscópico. Houve predomínio do sexo masculino com 76 por cento do total. A idade variou de 9 a 77 anos, com média de 37. A terceira década de vida foi a mais acometida no sexo feminino, enquanto que no masculino foi a quinta Cerca de 44 por cento da populaçäo provinha do interior de Sergipe. Foi observada predominância das manifestações da retocolite ulcerativa exclausivamente na porçäo retal, com 80 por cento. O sangramento foi a principal indicaçäo para a realizaçäo dos exames (355). Num total de 47 patologias associadas encontradas, as mais freqüentes foram hemorróida, papilite e plicoma. Em 76 por cento dos pacientes näo houve suspeita de parasitose como etiologia da retocolite ao exame retossigmoidoscópico. Os resultados deste trabalho demonstraram que a esquistossomose deve ser pesquisada, em sergipe e em regiões onde esta seja endêmica, como importante diagnóstico diferencial em pacientes com processo inflamatórios intestinais

ABSTRACT

BACKGROUND: Hepatitis C infection in hemodialysis units has been evaluated in different geographic regions. AIMS: The prevalence of anti-HCV in patients undergoing hemodialysis program in the city of Salvador, State of Bahia, Brazil, was studied and its association with transfusions, duration of hemodialysis and ALT elevation. METHOD: During a period of 17 months, all patients undergoing dialytic treatment, were evaluated. The total number of patients was 395, all of whom completed a questionnaire and provided serum samples for laboratory analysis. Serological levels were measured for ALT and the samples were tested for anti-HCV using ELISA II with a further confirmation using RIBA III. RESULTS: Anti-HCV was positive in 23.8 per cent (94/395). The presence of transfusions was associated with anti-HCV and as the number of transfusions used increased, so did the frequency of anti-HCV. Of the patients who never received transfusions, 12.5 per cent (6/48) were anti-HCV positive. The duration of dialytic treatment lasted from 53.44 +/- 36.45 months in the anti-HCV positive group and 22.10 +/- 22.75 months for the group testing negative. ALT elevation was more frequent in the anti-HCV positive group. Positivity for the RIBA III fractions was 79.8 per cent, 100 per cent, 80.9 per cent and 52.1 per cent, for c100-3, c33, c22 and NS5, respectively. The anti-NS5 was even less frequent in the group with elevated ALT. CONCLUSIONS: The prevalence of anti-HCV in patients undergoing chronic hemodialysis in Salvador, Bahia, is elevated and it is associated with transfusions, a longer duration of dialytic treatment and ALT elevation.

ABSTRACT

Neste estudo retrospectivo, testamos a qualidade da analgesia pós-operatória com morfina peridural em cirurgias orificiais, confrontando com os efeitos colaterais apresentados. Selecionamos 36 pacientes que utilizaram morfina-epidural (1,0 a 1,5 mg), analisando as incidências de prurido, depressäo respiratória, náuseas e vômitos, retençäo urinária, uso de analgésicos no pós-operatório imediato (POI) e a permanência hospitalar. Dividimos os pacientes em dois grupos, segundo a prescriçäo de analgésicos no POI: Grupo I (diclofenaco sódico, 75 mg, IM, SOS), Grupo II (diclofenaco sódico 75 mg, IM, 12/12h). A idade mínima e máxima foi respectivamente 21 e 57 anos com idade média de 34,5 anos com desvio padräo igual a 7,1. Resultados mostraram: ausência de depressäo respiratória; incidência relevante de retençäo urinária (47 por cento), com predominância masculina; e diferença na qualidade da analgesia pela potencializaçäo do diclofenaco associado à morfina, tendo 100 por cento de pacinentes sem dor no Grupo II contra 62,5 por cento no Grupo I (p < 0,05). Prurido (5 por cento) e náuseas e vômitos (25 por cento) foram inferiores a outros trabalhos descritos. O tempo de internamento foi 2-3 dias (94,4 por cento). A analgesia foi efetiva, contudo a incidência elevada de efeitos colaterais e o adequado controle da dor com outros métodos sistêmicos, talvez reservem o uso da morfina-peridural para casos de dor mais severa. Atualmente a associaçäo de agonista-antagonista ou antagonista com a morfina dá uma excelente analgesia com poucos efeitos colaterais

ABSTRACT

O vírus da hepatite C, recentemente descoberto, é o principal agente etiológico das hepatites pós-transfusionais, com percentual elevado de cronificação e evolução para carcinoma hepatocelular. Vários estudos têm se dedicado à compreensão da epidemiologia, evolução clínica e formas de apresentação da hepatite C. Desde 1990, a triagem de doadores de sangue com marcadores positivos para este vírus (antiVHC) reduziu, sensivelmente, a incidência de hepatite pós-transfusional, entretanto, criou dificuldades na interpretação clínica dos doadores de sangue antiVHC positivos...
