is present in 1. a retrospective medical chart review of individuals at least 18 years old with a total serum cholesterol level of at least 200 mg/dL or low-density lipoprotein cholesterol (LDL-C) level of at least 160 mg/dL handled at BMC’s general ACT-335827 internal medicine or family medicine clinics from 2003 to 2011. Individuals who had previously been prescribed lipid-lowering agents or thyroid medications were excluded. (To convert cholesterol and LDL-C to Tal1 millimoles per liter ACT-335827 multiply by 0.0259.) Demographic data and the proportion of patients with serum thyroid function testing obtained within about 6 months of the initial cholesterol elevation were determined. We ascertained the proportion of patients with abnormal serum thyroid-stimulating hormone (TSH) concentrations among those tested and determined whether patients were subsequently treated with levothyroxine within 6 months or with a lipid-lowering agent within 1 year. Results There were 8795 patients (mean [SD] age 53 [12] years; 55% were women; 45% African American; 24% white; 16% Hispanic) with new hyperlipidemia within the study period (Table).Thyroid function tests prices were higher among white patients (58%) than in additional races/ethnicities (45%-59%; < .01) and among ladies (60%) than males (37%; < .01). Desk Demographics of 8795 Patientsa Serum TSH level was examined within about six months from the hyperlipidemia analysis in 49.5% of whom 226 (5.2%) had an increased level: 151 (3.5%) had a TSH degree of 5 to 10 mIU/L; 74 (1.7%) had a TSH level higher than 10 mIU/L. Of these with an increased TSH level 114 (50.7%) were treated with levothyroxine including 52 of 74 individuals (70.3%) having a TSH level higher than 10 mIU/L. Eight hundred individuals (18.3%) also had peripheral thyroid function testing checked (21 [2.6%] got overt hypothyroidism; 89 [11.1%] subclinical hypothyroidism). Among individuals treated with levothyroxine just 25% (vs 44% of individuals with hyperlipidemia not really treated with levothyroxine) had been also recommended a lipid-lowering agent within 12 months (Shape). Shape Flowchart of Individuals Evaluated Discussion No more than 50% of individuals with recently diagnosed hyperlipidemia had been screened for thyroid dysfunction despite current recommendations. Testing led to a analysis of ACT-335827 hypothyroidism in 5.2% in keeping with findings in previous research.1 Individuals with TSH amounts higher than 10 mIU/L for whom levothyroxine treatment is preferred comprised only one 1.7% of screened individuals.6 Approximately 50% of these with elevated TSH amounts had been treated with levothyroxine; 30% of individuals with TSH amounts higher than 10 mIU/L weren't treated. Among individuals who received levothyroxine a significant proportion (75%)did not require a lipid-lowering agent within 1 year. Although 79% of these patients had correction of their hypothyroidism 60.5% did not have lipid levels rechecked. Among those whose lipid levels were rechecked 21 (61.8%) no longer had hyperlipidemia. Strengths of this study include the large sample and diverse inner-city population. However this was a retrospective study and we could not evaluate whether patients received screening and/or levothyroxine and antilipemic treatment at other medical institutions during the time frame studied. We conclude that the low rate of thyroid function testing in patients with new-onset hyperlipidemia demonstrates the need for more awareness of current guidelines. Future studies are needed to better understand reasons for low thyroid function screening rates among patients with hyperlipidemia and cost-effectiveness of hypothyroidism screening and treatment among these patients. Thyroid function screening guidelines for patients with hyperlipidemia may need revision if future studies demonstrate lack of cost-effectiveness; our results show that current guidelines may be underused.
