BACKGROUND: Acne treatment may fail or cause undesirable side effects due to inaccurate evaluation. High-frequency ultrasound (HFUS) can monitor systemic treatment in patients with moderate-to-severe acne vulgaris.
MATERIALS AND METHODS: In this prospective study, consecutive patients with moderate-to-severe acne vulgaris were recruited. Patients were graded by a comprehensive clinical assessment before and after therapy. Simultaneous HFUS grading was independently evaluated according to the sonographic scoring system for acne (SSSA). Clinical and HFUS grades were compared through kappa analysis.
RESULTS: A total of 70 patients were enrolled. At baseline, 36 (51.4%) and 34 (48.6%) patients were graded as moderate and severe, respectively, through clinical assessment. However, 27 patients (38.6%) scored SSSA-Grade II and 43 (61.4%) scored SSSA-Grade III in the HFUS grading. Sixty-one patients (87.1%) were in the consistent category as per clinical assessment and HFUS grades, with Kappa1 = 0.745, whereas higher HFUS grades were observed in nine patients. By the end of the observation, 65 of all patients (92.9%) showed significant improvement and 5 (7.1%) showed no apparent improvement after the treatment. According to the clinical assessment, 14, 52, and 4 patients were graded as mild, moderate, and severe, respectively. On the other hand, 11, 51, and 8 patients had SSSA-Grade I, II, and III, respectively. Of all patients, 63 (90.0%) had consistent evaluation results, with Kappa2 = 0.762, whereas the remaining seven patients had an HFUS grade higher than the clinical.
CONCLUSION: HFUS is a useful tool for dermatologists to monitor the treatment of moderate and severe acne vulgaris.
