We analysed the genetic changes in gp41 in a population of 30 heavily pretreated HIV-1-infected patients failing on a T-20-containing salvage therapy. This study confirms the key role of the number of drugs presumed to be still effective associated with T-20 in the magnitude of the virological response. Our results suggest that only HR-1 sequencing is necessary to characterize resistance to T-20, and that HR-2 domain sequencing is probably not required. 相似文献

We report the first 2 cases of visceral leishmaniasis in AIDS patients, which ocurred a few d after initiating antiretroviral therapy. The report raises the question whether a rapid immune reconstitution may convert a latent visceral leishmaniasis into a symptomatic one. 相似文献

3 cases of hairy cell leukaemia were studied with ultrastructural immunocytochemical methods using an anti human Ig HRPO-Fab fragment. Ig were detected on the cell surface, in the perinuclear cisterna and endoplasmic reticulum of hairy cells. Evidence of Ig in these sites demonstrates a B-lymphoid differentiation of the leukaemic cells. 相似文献

An immunoelectronmicroscopic method using Fab fragment of anti human IgG (H + L) has been employed to study the localization of cytoplasmic immunoglobulins in the tumoral cells of 12 B non Hodgkin's malignant lymphomas (B-M.L.). A comparison with normal homologous B lymphoid cells was performed on 10 non tumoral reactive lymph nodes. Immunostaining was observed in PNC, RER and Golgi complex. The criterions of differentiation were discussed in the different B-M.L.. Because of a granular hyaloplasmic immunostaining in normal and tumoral centroblasts and immunoblasts, monospecific antibodies against gamma, mu, alpha heavy chains were used to rule out a non specific uptake. Presence of mu heavy chain was discussed as an argument for immunoglobulin free ribosomal synthesis. 相似文献

We followed the course of cytomegalovirus (CMV) viremia in 65 patients treated with zidovudine for symptomatic HIV-1 infection. Blood samples were tested for the presence of CMV before initiation of treatment and every 3 months thereafter. 13 patients (20%) showed a positive CMV viremia at initiation of treatment. After 3 months of therapy, only 2 patients (3%) remained viremic. However, the frequency of CMV viremia increased from the 6th month of treatment and 28 (43%) of our patients showed a persistence of, or conversion to, positive viremia during the course of treatment. CMV viremia was associated with a decline in the patients' clinical state in 79% of the cases. In contrast, among the 37 patients, who remained negative for CMV viremia, 73% did not show a progression of the HIV-associated disease. The results suggest that CMV viremia could be considered as a useful marker for HIV-associated disease and its progression as well as for the efficacy of therapy. 相似文献
