Metabolic syndrome in older HIV-infected patients: data from the CORE50 cohort.
Metabolic abnormalities and cardiovascular disease are increasingly recognized in HIV-infected patients. While HIV-infected patients older than 50 years of age account for up to 25% of HIV cases in the United States, there are limited data on these individuals. To determine the prevalence and predictors of the metabolic syndrome among a cohort of older, HIV-infected patients and to calculate their 10-year Framingham cardiac risk (FCR) score a cross-sectional study of HIV patients older than 50 years of age was conducted at the CORE Center, Chicago, Illinois, between May 2005 and February 2006. There were 121 HIV-infected patients with a median age of 54 years, of whom 79% were male, 83% African American, 9% Hispanic, and 6% Caucasian. Thirty-four percent of patients had the metabolic syndrome, 49% had a moderate-high (>10%) 10-year FCR, and 13% had a high (>20%) 10-year FCR. Patients with the metabolic syndrome were significantly more likely to have a greater than 20% 10-year FCR. Sixty-five percent of all patients were current smokers and 55% of patients with the metabolic syndrome were current smokers. There were significant differences in the components of the metabolic syndrome by gender with women having significantly more components related to insulin resistance such as elevated waist circumference and diabetes, while men were more likely to have low high-density lipoprotein (HDL) levels. This study shows a high prevalence of the metabolic syndrome in older HIV-infected patients and an association between the metabolic syndrome and FCR in our study population. As the HIV population ages, attention to modifiable cardiac risk factors will become increasingly important.
