ABSTRACT

In order to establish the present prevalence of HCV in hemodialyzed patients (HD) from the city of La Plata, and to know the association between the prevalence and different variables, we have studied 217 hemodialyzed patients belonged to the Hemodialysis Unit of a Public Hospital and other 7 private Units. Serological reactivity to Anti HCV and Anti HBc IgG were investigated in all of them, as well as age, sex, number of transfusions, the time under dialysis treatment, the use of erythropoietin and hepatitis episodes were taken into account. We have found a prevalence of Anti HCV of 18.4% which was significantly superior to the blood donors' prevalence (P < 0.01) and significantly inferior to the one found in 1993 in HD patients of the same city (p = 0.002). We have found an association between the presence of Anti HCV and transfusions exposure, as well as more hemodialysis time. Our results may agree with the ones that suggest the aminotransferases are not good markers for hepatocellular injuries in Anti HCV (R) HD patients.

ABSTRACT

Para estabelecer la prevalencia actual de infección por HCV en pacientes hemodializados (HD) de la ciudad de La Plata y determinar su asociación con diferentes variables se estudiaron 217 pacientes con Insuficiencia Renal Crónica de una Unidad de Hemodiálisis de un Htal público y de 7 Unidades del medio asistencial privado. En la totalidad de los pacientes se investigó la presencia sérica de anti-HCV y de anti-HBc y se valoró la edad, sexo, número de transfusiones, antigüedad del tratamiento hemodialítico, uso de eritropoyetina y episodios de hepatitis. Se halló una prevalencia de anti-HCV del 18,4 por ciento significativamente superior a la de los donantes de sangre (P<0,01) y significativamente enor a la hallada en pacientes HD de la misma ciudad en 1993 (P=0,002). También se encontró que la presencia de anti-HCV se asocia con el antecedente de haber recibido transfusiones y con mayor tiempo de ento hemodialítico. Nuestro resultados parecen coincidir con los que sugieren que las aminotransferasas en pacientes HD anti HCV © son un mal marcador de lesión hepatocelular.

ABSTRACT

Independent transgenic mouse lines carrying the mouse Mos protooncogene linked to a retroviral transcriptional control sequence display behavioral abnormalities including circling, head tilting, and head bobbing. This dominant phenotype shows various degrees of penetrance in different transgenic founder animals and lines. Neuronal and axonal degeneration, gliosis, and inflammatory infiltrates are found in all transgenic mouse lines in which behavioral traits are present. Recordings of auditory-evoked potentials in mice of one of these lines demonstrate that transgenic mice are deaf; in these mice spiral ganglia degenerate and most of the cochlear hair cells are absent. By using an S1 nuclease protection assay, we have detected RNA expression of the transgene in all tissues examined and, in particular, at high levels in brain. In situ hybridization experiments show that Mos expression can be detected in specific areas of the central nervous system. Lesions are present in areas with demonstrable overexpression of Mos.
