Here we analyzed the relationship between the CD4 lymphocyte cell count and the clinical response to chemotherapy. Methods: The 176 HIV infected patients with advanced KS who failed to respond to prior HAART were selected. All these patients were then preceded to chemotherapy with ABV regimen which was administered at 3 weekly intervals for 6 cycles. For each patient CD4 cell count was done before starting chemotherapy and after finishing 6 cycles of chemotherapy. The difference of CD4 cell counts pre chemotherapy and post chemotherapy was compared with the clinical progress of the patients after 6 cycles of chemotherapy. Results: The overall clinical remission was shown in 93.7% patients. Progressive disease (PD) and no change in clinical condition (NC) was shown in 6.3% patients. The increase in CD4 cell count post chemotherapy was found in 89.8% patients and the decrease in CD4 cell count was seen in 10.2% patients. The difference of the mean CD4 cell counts for patients in group CR + PR (complete relief + partial relief) before and after chemotherapy was highly significant. The difference of the mean CD4 cell counts for patients in group NC + PD before and after chemotherapy was not significant. The difference in CD4 cell counts in CR + PR and NC + PD groups before and after chemotherapy was highly significant. Conclusion: The HIV related KS patients on HAART benefit from the chemotherapy as it increases the CD4 cell count and it has positive impact on clinical remission of KS.展开更多

However,gastrointestinal disease continues to account for a high proportion of presenting symptoms in these patients. Gastrointestinal symptoms in treated patients who respond to therapy are more likely to the result of drug-induced complications than OI. Endoscopic evaluation of the gastrointestinal tract remains a cornerstone of diagnosis,especially in patients with advanced immunodeficiency,who are at risk for OI. The peripheral blood CD4 lymphocyte count helps to predict the risk of an OI,with the highest risk seen in HIV-infected patients with low CD4 count (< 200 cells/mm3). This review provides an update of the role of endoscopy in diagnosing OI in the upper gastrointestinal tract in HIV-infected patients in the era of HAART.展开更多
