Integration of high-frequency ultrasound with the Global Acne Grading System for prediction of treatment efficiency in acne vulgaris.

ABSTRACT:

Purpose

This study aimed to establish a novel acne scoring system (GAGS-HFUS) that combined the Global Acne Grading System (GAGS) with high-frequency ultrasound (HFUS), and to evaluate its predictive value for unfavorable treatment response in patients who have moderate-to-severe acne.

Methods

This prospective study recruited consecutive patients with mild-to-severe acne vulgaris. The GAGS-HFUS was developed based on the HFUS-detected morphological characteristics of acne and the GAGS facial region classification. Acne severity was assessed using both ultrasonic scales (the GAGS-HFUS, Sonographic Scoring System for Acne [SSSA], and Sonographic Scoring of Acne [SOS-Acne]) and a clinical scale (the Investigator Global Assessment [IGA]). Three months of followup were conducted
