title: Evaluation of leptin, adiponectin, and ghrelin levels in patients with acne vulgaris.
abstract: BACKGROUND
  The research evaluating adipokines are very few in patients with acne vulgaris. The hypothesis that hyperinsulinemic and high glycemic index diet plays a role in the pathogenesis of acne is still controversial. In this study, we aimed to evaluate adipokines such as leptin (L), adiponectin (A), ghrelin and A levels, and A/L rates that indicate insulin resistance in nonobese patients with severe acne vulgaris.
  
  
  METHODS
  Thirty patients who are nonobese with moderate acne vulgaris, aged 18 to 25 years, and 15 age-sex compatible controls were included in our study. The acne lesions were assessed using the Global Acne Grading Scale (GAGS). All participants were evaluated for the parameters that may affect the metabolism of serum L, A, and ghrelin levels in blood, and their body mass index were calculated. The significance level was determined as p ≤ 0.05.
  
  
  RESULTS
  Of the 30 patients, 17 were women and 13 were men. The mean age was 20.60 years and the mean duration of the disease were 2.8 years. All of patients had moderate acne vulgaris (GAGS 19-30). Of the 15 controls, 11 were women and 4 were men. The mean age was 21.20 years. There were not a statistically significant difference in L, ghrelin, A levels, and A/L ratio between the two groups.
  
  
  CONCLUSIONS
  Adipokines may have a role in the pathogenesis of acne vulgaris. L, A, ghrelin, and insulin resistance may not participate in the responsible mechanisms in nonobese patients with moderate acne vulgaris.
