Forms of dyslipidemia are very common in individuals affected by polycystic ovary syndrome (PCOS), but in addition to plasmatic lipids, it is necessary to evaluate the alterations in the atherogenic lipoproteins (Lp) and apolipoproteins (apo). In our study we measured the concentrations of apoB, Lp(a) and low density lipoproteins (LDL) in 42 patients with PCOS (age: 28 +/- 7 years, body mass index: 27 +/- 5 kg/m-) and 37 healthy women (of the same age and body mass index). Methods: values of Lp(a) >30 mg/dl were considered high, whereas for apoB, values >100 g/l were considered high. Results: the patients with PCOS showed an increase in triglycerides (p=0.0011) and low levels of high density lipoproteins (HDL) (p=0.0131), but the total cholesterol and the LDLs were not significantly different to those of the control group. High levels of Lp(a) were found in 24% of the individuals with PCOS, and a smaller number showed high levels of apoB (14%). This analysis shows that the concentrations of Lp(a) are only correlated to the HDL levels (r =0.378, p= 0.0431). 36% of the patients with PCOS with normal levels of plasmatic lipids show high levels of Lp(a) and apoB, and small and dense LDLs. Conclusions: alterations in the plasmatic lipids are present in 1/3 of the women affected by PCOS. More research is necessary to better understand the mechanisms responsible to reduce the risk of cardiovascular problems in young women with polycystic ovary syndrome.
