INTRODUCTION: Ghrelin has anti-inflammatory and immunomodulatory activities. Data about the role of ghrelin and ghrelin polymorphisms in the development of acne vulgaris in post-adolescent male patients are limited.
AIM: To evaluate the role of serum androgens, insulin resistance, ghrelin and ghrelin polymorphisms in severe acne vulgaris.
MATERIAL AND METHODS: Thirty-five post-adolescent male patients with a mean age of 28.0 ±5.4 years and 33 age-and BMI-matched controls were enrolled. Serum androgens, lipids, insulin sensitivity parameters and ghrelin levels were determined. The PCR method was used for GHRL polymorphisms (rs27647, rs696217 and rs34911341 genotypes).
RESULTS: Patients had similar anthropometric measures to controls, except a significantly higher WHR in patients (0.92 ±0.06 vs. 0.86 ±0.08, p < 0.05). Also, FPG, HOMA-IR values, lipid profile and serum androgen levels were similar. Interestingly, patients had significantly lower ghrelin levels than controls (4.5 ±5.8 vs. 101.2 ±86.5 pg/ml, p < 0.001). The frequencies of rs696217 and rs34911341 genotypes were similar whereas the distribution of rs27647 alleles was significantly different between the groups (p < 0.05). GA and GG genotypes of GHRL rs27647 polymorphism indicated an increased risk of developing acne vulgaris (OR = 11.156, 95% CI: 2.864-43.464, OR = 5.312, 95% CI: 1.269-22.244, respectively; p < 0.05). Patients with rs27647-AA polymorphism had significantly lower GAGS scores than other groups (AA genotype 6.7 ±14.1 vs. GA genotype 24.6 ±15.7 and GG genotype 19.4 ±17.9, p < 0.001). None of the polymorphisms had a significant effect on metabolic parameters, insulin sensitivity and serum ghrelin levels.
CONCLUSIONS: Decreased ghrelin levels and GA and GG genotypes of GHRL gene rs27647 polymorphism may have a role in the pathogenesis of acne vulgaris.
