Therapeutic Response of Vitamin A, Vitamin B Complex, Essential Fatty Acids and Vitamin E in the Treatment of Phrynoderma: A Randomized Controlled Study

Abstract

Background: In the treatment of phrynoderma, various nutrients have been tried in different dosages and routes with variable therapeutic outcomes.Aims: The present study was undertaken to compare the efficacy of various nutrients in the treatment of phrynoderma. Settings and Design:An open label randomized controlled study was conducted in the out-patient department of Dermatology in a tertiary care hospital. Material and Methods:The patients were divided into group of five and each patient received one of the five regimens [10 injections of Vitamin A 1 lakh units, intramuscularly (IM) on alternate day, 10 injections of Vitamin B complex, 2cc IM on alternate day, 2 table spoon of safflower oil, two times daily with meals, Tab Vitamin E 400mg once daily, and only topical keratolytic (salicylic acid 3% ointment) two times daily] respectively. The first four regimens also received topical keratolytic. The primary outcome measured was therapeutic response at the end of regimen. The response was graded based on the percentage of flattening and decrease in number of lesions. Less than 25% improvement was graded as poor, 26-50% improvement as moderate, 51-75% improvement as good, and more than 75% improvement as excellent response. In the statistical analysis, comparison was done using Chi-square and Fisher's exact test.Results: A total of 125 patients were included in the study with 25 patients each in five regimen groups. There were 79 (63.2%) males and 46 (36.8%) females with a ratio of 1.72:1. The age of the patients ranged from 3 to 26 years with mean of 10.1±4.3 years. Out of 125 patients, 105 completed the study. In regimen 1 and 2, significant number of patients showed good to excellent response whereas significant number of patients in remaining regimen showed moderate to poor response with a p value of <0.05. The therapeutic response to Vitamin A and Vitamin B complex therapy was significantly better than other regimens.Conclusion: Intramuscular injections of Vitamin A or Vitamin B are effective in the treatment of phrynoderma. Addition of topical keratolytics helps in faster clearance of keratotic lesions.

“…Fig. S6 The use of vitamins in topical applications for daily skin care typically involves B-complex vitamin formulations because of potential synergetic effects on anti-aging or oxidative stress reduction [5,49,50]. Accordingly, we determined the antioxidant activity of a B-complex formulation, namely composed of 2.4 mg of B1, 32 mg of B3, 10 mg of B5 and 2.6 mg of B6, prepared based on the daily Dietary Reference Intake (DRI) approved by the Food and Drug…”

“…The main roles of vitamin B are in catabolic metabolism for energy production, and in anabolic metabolism for the transformation of specific bioactive molecules [2]. The use of formulations combining several vitamins from complex B to reach synergetic effects is common in food supplementation [3] and skin care [4,5].…”

Vitamin B group levels and supplementations in dermatology: Review of the literature

“… 17-20 Vitamin B complex injection (each mL contains: B1 (thiamine HCl) 100 mg, B2 (riboflavin-5-phosphate sodium) 2 mg, B3 (niacinamide) 100 mg, B5 (dexpanthenol) 2 mg, B6 (pyridoxine HCl) 2 mg) has also shown a significant role in the management of phrynoderma whereby intramuscular dual therapy with safflower oil or with vitamin E improved and smoothed out the appearance of lesions. 21 Nicotinamide treatment has also shown benefit cosmetically in melasma and hyperpigmentation. 22 , 23 Patients likely to be deficient in niacin include those living in poverty, those with eating disorders or eating a nutritionally incomplete diet, especially high corn diets, alcohol abuse, liver cirrhosis, inflammatory bowel disease, and those with advanced AIDS.…”
