Effectiveness of Standard Therapy for Acne Vulgaris Based on Clinical Practice Guidelines in Indonesia.

Abstract

Purpose: To evaluate the effectiveness of standard therapy for acne vulgaris based on Indonesian guidelines.

Patients and methods: New patients with acne vulgaris at Dr. Cipto Mangunkusumo National Central General Hospital, the national referral center in Indonesia, who met the criteria were included in this study. Patients were treated with standard therapy for acne vulgaris based on the 2017 guidelines of Dr. Cipto Mangunkusumo Hospital, depending on severity. Changes in the number of non-inflammatory, inflammatory, and total lesions and the proportion of acne severity after three months of therapy were analyzed retrospectively.

Results: Among the 131 subjects, 63.4% had moderate acne; 20.6% had mild acne, and 16% had severe acne at baseline. Most patients (29 (22.2%)) received a combination of retinoic acid, benzoyl peroxide, and topical or oral antibiotics. Standard therapies reduced the median of non-inflammatory (25 (5-135) vs 8 (0-53)), inflammatory (10 (0-93) vs 2 (0-22)), and total lesions (41 (10-160) vs 10 (1-71)) at week 12 (all p < 0.001). The proportion of acne severity differed significantly after three months, with an increasing proportion of mild acne (20.6% vs 93.1%) and a decreasing percentage of moderate and severe acne (moderate = 63.6% vs 6.1%; severe, 16% vs 0.8%; p < 0.001).

Conclusion: Standard therapy for acne vulgaris based on the clinical practice guidelines in Indonesia improved acne lesions and severity after 12 weeks. These results support the implementation of national guidelines for acne management in Indonesia, with the practice of improving antimicrobial stewardship.
