CD4 and Kaposi's sarcoma: Dupont et al (2000) found that an increase in the CD4 cell count of more than 150 × 106 l−1 after 12 months of HAART was predictive of complete remission from KS at month 24 in HIV-infected patients. Similarly, Cattelan et al (1999) found a positive correlation between the CD4 cell count and KS control during antiretroviral therapy. In contrast, like us, Nasti et al (2003a, 2003b) found that HIV suppression was associated with good KS outcomes, independently of immune restoration reflected by the CD4 cell count.
