Article: The effect of ABV regimen on CD4 lymphocyte count in patients with advanced HIV related Kaposi’s sarcoma[show abstract] [hide abstract]
ABSTRACT: ObjectiveThe combination of highly active antiretroviral therapy (HAART) and chemotherapy with ABV regimen (doxorubicin, bleomycin and vincristine) is a promising approach for the treatment of advanced HIV-related Kaposi’s sarcoma (KS). Here we analyzed the relationship between the CD4 lymphocyte cell count and the clinical response to chemotherapy. MethodsThe 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. ResultsThe 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. ConclusionThe 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.
