Abstract: | The objective of this study is to characterize the lipoprotein risk levels in Takayasu arteritis (TA) patients and its possible
association with disease activity and glucocorticoid use. Twenty-five female TA patients were consecutively included and compared
with 30 age-, gender-, and body mass index-matched healthy controls. Demographic features and the lipid profile were determined
and cardiovascular risk levels were evaluated according to NCEP/ATPIII. Total cholesterol (TC), LDL-c, HDL-c, and triglycerides
were determined after a 12-h overnight fast. Exclusion criteria were conditions that interfere in the lipid profile. The disease
duration was 6.6 ± 7.4 years; 30% had clinical activity and 80% had laboratory activity. Regarding NCEP/ATPIII risk levels,
TA patients presented higher frequency of lipid risk compared to controls: high TC (48% vs. 20%, p = 0.04), low HDL-c (20% vs. 0%, p = 0.015), and high triglycerides (36% vs. 10%, p = 0.026). No difference was observed related to LDL-c risk levels between both groups (40% vs. 20%, p = 0.14). Remarkably, 60% of the patients had at least one lipid risk factor for cardiovascular disease. No difference in
the lipids was observed between patients with and without clinical activity; however, those with laboratory activity showed
lower levels of HDL-c (1.37 ± 0.42 vs. 2.00 ± 0.63 mmol/L, p = 0.012) than patients without this activity. A negative correlation was found between HDL-c and CRP levels (r = −0.42, p = 0.04). Lipids were similar in patients under glucocorticoid compared to those without this therapy. This is the first study
to identify that TA, an inflammatory disease, has a proatherogenic lipid profile which is associated to laboratory disease
activity. |
