This is a crossover interventional study of 26 HIV-infected patients on stable ART with low density lipoprotein cholesterol (LDL-C) >100 mg/dL, not receiving any lipid-lowering treatment. After a 3-week lipid stabilization period with a standardized diet regimen, the effect of a 3-month oral NC containing red yeast rice-derived monacolin K 3 mg, berberine 500 mg, policosanol 10 mg, astaxanthin 0.5 mg, folic acid 0.2 mg and coenzyme Q10 2 mg vs no active treatment (noNC) was tested on plasma total cholesterol (TC), LDL-C, high density lipoprotein cholesterol (HDL-C), triglyceride, lipoprotein(a), PCSK9, high-sensitivity C-reactive protein (hsCRP) levels and aortic pulse wave velocity (aPWV).
