To define the extent and time course of HIV-proteinase inhibitor (PI) effec
ts on serum lipid levels 148 patients on triple combination therapy includi
ng PIs and 91 patients on therapy with two nucleosides as a control group w
ere evaluated. In the PI group there was a significant increase in total ch
olesterol after 3, 6 and 12 months compared to the baseline level (198, 204
and 203 vs. 176 mg/dl). The increase in triglycerides was 25.5% from the b
aseline at month 3. Indinavir had a significantly higher impact on choleste
rol levels than saquinavir. No changes in lipids were seen in the control g
roup. It was concluded that hyperlipidemia is associated with PI use, becom
es evident within 3 months of treatment and seems to be substance specific.
