Abstract
Acanthosis nigricans (AN) is a skin disorder that is characterized by?dark?discolorations?with?velvety?texture.?The?safety?and?efficacy? of using metformin as adjunctive therapy to the topical agents in AN remain uncertain. Our primary objective is to quantify AN severity improvement.
Introduction
Acanthosis nigricans (AN) is a common benign skin disorder that is characterized by a symmetrical distribution of dark brown to black discoloration of the skin. It is associated with thickened and velvety texture of the skin. It especially occurs in the skin folds, and more observable in the neck, axilla, groin, or under the breast.
Methods
Eligible subjects aged 12-50 years of either gender diagnosed with AN by a consultant dermatologist. Subjects were ineligible if they had a diagnosis of malignant AN, renal or hepatic impairment, pregnancy, lactation, diabetes mellitus, and subjects who are currently using metformin.
Results
A total of 17 Saudi subjects, 9 were assigned to treatment group and 8 as the control group ( Figure 1 ). There were insignificant differences between study and control group at baseline characteristics ( Tables 1a and 1b ).
Discussion
All subjects had obesity except three cases had a healthy body weight as their BMI 18.50 to 24.99 kg/m2 [ 19 ]. Obesity defined as BMI ≥ 30 kg/m2 for adult, and ≥ 95th percentile BMI for age for either genders19. Obesity, PCOS, and HOMA-IR all strongly suggest IR, and more likely developing DM2 in future [ 20 - 22 ].
Conclusion
Metformin as adjunctive therapy seems to be well-tolerated, and effective in enhancing the relief of neck AN severity and texture in obese subjects, while it is ineffective in familial AN. Future studies with histopathological grading, and with larger sample size are needed to confirm our results.
