Abstract
Abstract Background Acne is a chronic inflammatory disorder of the pilosebaceous unit. Oral isotretinoin is a highly effective treatment for patients with moderate and severe, but causes significant side effects. Objective To estimate homocysteine level in acne patients after treatment with isotretinoin. Patients and Methods The prospective study was conducted at Ain Shams University Faculty of Medicine, Egypt, from June 2017 to November 2017, including male or non-pregnant female patients more than 18 years of age, categorized by the Global Evaluation Acne (GEA) into 22 patients with moderate acne vulgaris and 22 patients with severe acne. Isotretinoin was started in a dosage of 0.5 mg/kg/day, and 1.0mg/kg/day in moderate and severe acne patients respectively. Baseline homocysteine level, liver function tests, serum cholesterol and lipid profile were tested before and after 3 months. Results There was significant difference (p = 0.001) in homocysteine level among all cases Moreover, homocysteine serum level in patient's group who received high dose isotretinoin (1 mg/kg/d) showed highly significant results (p = 0.001) in contrast to patient's group who received low dose isotretinoin (0.5 mg/kg/d) = 0.003). A significant increase in lipid profile and liver function test was seen in all cases. Conclusion low dose isotretinoin seems to have less side effects on basic laboratory data such as CBC, liver function tests, lipid profile and homocysteine serum levels than high dose.
