The role of impaired glucose and lipid metabolism and liver enzyme abnormalities in the formation of multiple acrochordons: a case-control study

Abstract

Background Acrochordons, one of skin tumors, are protrusions of the loose fibrous tissue. In various studies, they have found to be associated with abnormal lipid profile, diabetes, cardiovascular disease, obesity, abnormal liver enzymes and genetic factors. In our case-control study, we aimed to determine possible associations of multiple acrochordons with obesity, impaired glucose and lipid metabolism, thyroid disorders, anemia and liver enzymes abnormalities.Methods Sixty-five patients (32 male, 33 female) with at least 8 skin tags and age- and gender-matched 60 controls without skin tags (30 male, 30 female) were enrolled to the study. We noted patients’ and controls’ age, height, weight, body mass index (BMI) and detailed medical history. Locations of acrochordons were recorded for the patient group. We recorded values of fasting plasma glucose, insulin, homeostatic model assessment insulin resistance (HOMA-IR), total cholesterol, triglyceride, high-density lipoprotein (HDL), low-density lipoprotein (LDL), free T3 (fT3), free T4 (fT4), thyroid-stimulating hormone (TSH), hemoglobin, ferritin, vitamin B12, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP).Results Our study has shown a genetic predisposition to the development of multiple skin tags (P=0.0001). The mean BMI was statistically significant between the patients and controls (P<0.0001). In addition, we have found that when fasting plasma glucose, AST and GGT levels increase, the possibility of the forming of multiple acrochordons also increases (P=0.048, P=0.003, P=0.013). We determined that increasing of BMI is a risk factor for both genders (P=0.003, P<0.0001, respectively). We found that elevated fasting plasma glucose, insulin, HOMA-IR, total cholesterol, triglyceride, AST, ALT and GGT levels increase possibility of the forming of multiple acrochordons in females (P=0.037, P=0.022, P=0.013, P=0.03, P=0.007, P<0.0001, P=0.015, P=0.005, respectively).Conclusion Our results show that multiple acrochordons may be the cutaneous signs of abnormal glucose and lipid metabolism and liver enzyme abnormalities. Thus, we suggest that clinicians should see appropriate bloodtests for patients with multiple skin tags and manage them accordingly.
