Cotton from Boehringer Ingelheim in the UK did a meta-analysis of six published studies in which the protease inhibitor (PI) component of HAART was switched to nevirapine. Overall 307 patients were enrolled in the studies. There was general consensus in terms of response of serum cholesterol and triglycerides. Total cholesterol fell from a mean of 231 to 210 at 6 months; triglycerides fell from a mean of 295 to 231 at 6 months. In half of the studies, mean cholesterol and mean triglycerides fell to below 200 by 6 months. No significant changes in blood glucose at baseline or after the switch. Three of the five studies reported improvement in body shape. Meanwhile viral suppression was generally maintained.
