| We have determined the number of circulating T, B and natural killer cells in renal transplant recipients in order to detect changes during cytomegalovirus (CMV) infections. Serial blood samples were taken from 61 patients on standard triple immunosuppression therapy (cyclosporin A, azathioprine and prednisone). Using two-color flow cytometry analysis, the absolute number of CD3+, CD4+, CD8+, CD19+, CD3+HLA-DR+ and CD16+56+ cells was determined. Forty-eight patients (78.7%) developed active CMV infection, and all of them subsequently recovered. Twenty of the infected patients (32.8%) presented symptoms compatible with CMV disease during the infectious process. The number of lymphocytes and their main subpopulations were normal before the onset of CMV... |

| The best strategy for control of cytomegalovirus (CMV) infection in lung transplant patients is still not determined. The aim of this study was to document the incidence of CMV infection in a cohort of lung transplant recipients under universal prophylaxis with intravenous ganciclovir. All patients received immunosuppressive regimens consisting of cyclosporine, azathioprine, and prednisone. Regardless of CMV serostatus, intravenous ganciclovir was prescribed for every patient in the first 3 months post-transplantation. CMV infection was defined as the detection of CMV pp65 in leukocytes. Eighty-two lung transplant patients were included over a 5-year period. The incidence of CMV infection in the first year post-transplantation was 68.3%, occurring after a... |

| O Vírus da leucemia felina (FeLV) pertence à família Retroviridae, gênero Gammaretrovirus. Diferentemente de outras retroviroses, uma parcela dos gatos jovens e adultos exposta ao FeLV não apresenta antigenemia/viremia, de acordo com as técnicas convencionais de detecção viral, como isolamento em cultivo celular, imunofluorescência direta e ELISA. O emprego de técnicas de maior sensibilidade para detecção e quantificação viral, como o PCR quantitativo, permitiu a identificação de animais positivos para a presença de DNA proviral e RNA na ausência de antigenemia/viremia e, com isso, um refinamento da análise das diferentes evoluções da infecção. Assim, reclassificou-se a patogenia do FeLV em 4 categorias: infecção abortiva, regressiva, latente e... |
