The metabolic profile in patients with skin tags.

Although skin tags are associated with diabetes mellitus, insulin resistance, hypertension, obesity, atherogenic lipid profile, no data in the literature show that the presence of skin tags is associated with serum high-sensitive C-reactive protein, uric acid, free fatty acid and leptin level. The purpose of this study was to evaluate the frequency of hypertension, dyslipidemia, insulin resistance and obesity in patients with skin tags and to compare patients with skin tags and normal healthy subjects for insulin resistance, serum lipids, insulin, glucose, leptin, high-sensitive C-reactive protein, free fatty acid levels. We evaluated 113 patients with skin tags and 31 healthy subjects. The two groups were compared with respect to BMI, lipid profile, blood pressure, insulin resistance, serum lipids, insulin, glucose, leptin, high-sensitive C-reactive protein, free fatty acid and homeostatic model assessment of insulin resistance (HOMA-IR). Total 53.9 and 33.6% of patients with skin tags were overweight and obese, respectively. The frequency of hypertension 30.1%, dyslipidemia 59.3% and insulin resistance 21.2% were detected. HOMA-IR (P < 0.001) and serum glucose (P < 0.001), insulin (P = 0.002), high-sensitive C-reactive protein (P = 0.001), uric acid (P = 0.001), free fatty acid (P = 0.002), HbA1c (P < 0.001), total cholesterol (P = 0.018), LDL-cholesterol (P = 0.023), and triglyceride levels (P = 0.001) were higher in patients with skin tags than control group. Overweight and/or obesity, dyslipidemia, hypertension, insulin resistance and elevated high-sensitive C-reactive protein are seen in patients with skin tags. Skin tags may be a marker of increased risk of atherosclerosis and cardiovascular disease.
