High-Dose Isotretinoin Treatment and the Rate of Retrial, Relapse, and Adverse Effects in Patients With Acne Vulgaris

This study was carried out to evaluate the efficacy, safety and adverse effects of topical isotretinoin 0.05% gel in the treatment of acne vulgaris. This prospective study was undertaken in Skin & VD outpatient department of Rajshahi Medical College Hospital, Rajshahi. One hundred patients with mild tomoderate acne vulgaris were enrolled and were instructed to apply isotretinoin 0.05% gel once daily at night for 12 weeks. Patients were followed up at 2,4,8 and 12 weeks for efficacy and tolerability. Efficacy was measured by counting facial inflammatory and noninflammatory lesions and by grading acne severity. Cutaneous tolerance was assessed by determining erythema, scaling and burning with pruritus.Response was excellent in 80%of cases.None of the cutaneous reactions was severe, all were mild and well tolerated.Nobody had to discontinue the therapy for side effects. This study confirms that isotretinoin 0.05% gel is safe and effective topical therapy for mild to moderate acnevulgaris.TAJ 2016; 29(2): 1-5

Anti Inflammatory

Background: Topical adapalene and tretinoin, are comedolytic, anti-comedogenic and anti-inflammatory, on RAR (α, β, γ) receptors binding. Adapalene enables quicker follicular penetration, by lesser anti-AP-1 (c-Jun, c-Fos) and no CRBPII mRNA actions, causing chemical stability, lipophilicity and less photo-lability, producing lesser photosensitivity and no skin irritation, unlike tretinoin; wherein reducible by overnight application and combination therapy, slow-release polymers or emollients, respectively. Topical nadifloxacin is bactericidal, anti-inflammatory and comedolytic, with inhibitory effect on DNA gyrase, DNA topoisomerase IV and IL-1α, IL-6, IL-8. The Global Alliance to Improve Outcomes in Acne Guidelines recommend synergistic and additive combination therapies, which enhance therapeutic efficacy and reduce adverse effects. Due to inadequacy of data, this study was conducted, to compare the safety among topical anti-acne monotherapies and combination therapies, and to easily detect any adverse effect producing component in the topical combination therapy.Methods: In this multi-centre, prospective, randomised, open-labelled, comparative study, groups A, B, C, D and E (20 patients each), applied topical 1% nadifloxacin monotherapy, 0.1% adapalene monotherapy, 0.025% tretinoin monotherapy, 1% nadifloxacin and 0.1% adapalene combination therapy and 1% nadifloxacin and 0.025% tretinoin combination therapy, respectively, over their facial mild to moderate acne lesions, once daily overnight; and adverse effects, like erythema, scaling, dryness, prutitus, burning, or stinging, were assessed on 0, 15, 30, 60, 90 days and follow-ups, by Local Irritation Scale.Results: In all 5 groups, no adverse effects were observed, with no statistically significant difference among the observations.Conclusions: The therapies were well tolerated and safe among all 5 groups.

Proven Efficacy

Background: Both salicylic acid (SA) and trichloroacetic acid (TCA) have proven efficacy with goodsafety profiles in the treatment of acne vulgaris. Objectives: This study compared the clinical efficacy and safety of 25% TCA and 30% SA peels in thetreatment of mild and moderate acne vulgaris. Methods: Patients with mild or moderate acne vulgaris were randomized into 2 groups of 25 personseach, and treated with either the TCA peel or the SA peel at 2-week intervals for 12 weeks. Evaluationof active acne was done by individual lesion counts (comedones, papules and pustules) and calculationof the Michaelsson acne score (MAS). Results: Both peels led to significant decrease in individual lesion counts and MAS compared to baselinevalues, without significant differences between the treatment groups. Thus, the peels had equivalentefficacy against acne vulgaris. The TCA peel was better in treating non-inflammatory lesions,while the SA peel was better for inflammatory lesions, but the differences were not significant. Noserious adverse effects were recorded, but more patients in the TCA peel group experienced burningand stinging sensations. Conclusion: The efficacy of 25% TCA is comparable to that of 30% SA in mild-to-moderate acnevulgaris, but safety and tolerability were better with the SA peel than TCA peel.
