The primary virologic end point was the percentage of patients with plasma HIV RNA 500 copies mL at months 6 M6 12 M12 and 18 M18 . The primary analysis was done as intent-to-treat. Results The staging of HIV disease performed using the definitions of the US Centers for Disease Control and Prevention CDC was CDC stage B or C for all 40 recruited patients. At baseline the mean CD4 cell count was 133 92 mcL standard deviation SD range 1346 and 23 of patients had CD4 cell counts below 50 mcL. The mean baseline plasma HIV RNA level was log10 .
