Objectives:There are limited data regarding omalizumab in the treatment of recalcitrant chronic spontaneous urticaria (CSU) in Asian populations. This study evaluated the effectiveness and the proper dosage of omalizumab for Asian CSU patients in a real-life setting. Methods:We retrospectively reviewed recalcitrant CSU patients seeking treatment at the Skin Allergy Clinic, Siriraj Hospital during the 3-year period. All patients were treated with omalizumab as an add-on therapy. Standard seven-day urticaria activity score (UAS7) and medication score were used to assess omalizumab response. Results:Of 13 patients, 9 patients (70%) responded well to 150 mg omalizumab injection every month, whereas 4 patients requiring updosing to 300 mg. In the 150 mg group, one patient achieved complete symptom control without antihistamine intake. Most of them required antihistamines without prednisolone and ciclosporin. Onset of omalizumab was fast, usually within the first week. Though only two patients in the 300 mg group achieved complete absence of symptoms, ciclosporin and oral corticosteroids could be discontinued. No patients reported adverse effects. Conclusions:Omalizumab at an initial dosage of 150 mg was effective in the treatment of recalcitrant CSU among Asians. Updosing to 300 mg was required to achieve satisfactory outcomes.

Introduction: Topical retinoids are considered to be the first-line agents and maintenance therapy of acne; however, irritation side effects are major concern issues. Noncomedogenic moisturizers are sometimes added to relieve cutaneous irritations. This study aimed to compare tolerability and efficacy of moisturizers containing licochalcone A,l-carnitine and 1,2-decanediol (active formulation) with a placebo in mild to moderate severe acne in Asian subjects.Methods: This was an 8-week double-blind, prospective, randomized controlled study. All patients (n = 120) were randomized equally into three groups: (A) adapalene gel, (B) adapalene gel with the active formulation and (C) adapalene gel with the placebo. The severity of acne, skin bioengineering measurements and skin tolerability were recorded during the study.Results: Compared to baseline, the active formulation group showed significant reductions in inflammatory lesions and total lesions at the end of the study without flare-up. Moreover, skin irritations were less detected than in the other two groups by corneometer and transepidermal water loss measurements.Conclusions: The concomitant usage of adapalene gel and the moisturizer containing licochalcone A,l-carnitine and 1,2-decanediol could reduce undesirable side effects without interfering the efficacy of adapalene. This moisturizer may be superior to placebo to prevent cutaneous irritations and enhance patients’ adherence to acne medications. [ABSTRACT FROM PUBLISHER]
