A Cross‐Sectional Analysis of Quality of Life in Japanese Acne Patients Using the Japanese Version of Skindex‐16

Self Cite

There are few clinical studies which compare the efficacy and patient satisfaction for oral antibiotics to treat inflammatory acne. To clarify the difference between oral antibiotics, acne patients with moderate to severe inflammatory eruptions were randomized into three groups, and each patient was given minocycline (MINO), roxithromycin (RXM) or faropenem (FRPM) for 4 weeks, followed by 4 weeks of observation without any oral antibiotics. We estimated the reduction rate of inflammatory lesion counts, the scale of Skindex-16 which represents patient quality of life (QOL), and minimum inhibitory concentrations required to inhibit the growth of 90% of Propionibacterium acnes isolated from acne patients (MIC(90) ). In all three groups, inflammatory lesion counts, and emotional and total score of Skindex-16 were significantly improved (P<0.05) after 4 weeks treatment, and these effects were maintained for the following 4 weeks. Dizziness/nausea in two patients (4.1%) of the MINO group and diarrhea in three patients (5.9%) of the FRPM group were observed. There was no significant difference of percentage reduction in inflammatory lesion counts and incident rates of side-effects between these three oral antibiotics. MIC(90) of MINO was 0.25 μg/mL before and after treatment, but MIC(90) of RXM had increased from 0.25 μg/mL to more than 32 μg/mL after treatment. MIC(90) of FRPM was 0.06 μg/mL or less for all strains before and after treatment. Our randomized controlled clinical trial suggested that MINO, RXM and FRPM were efficient to improve inflammatory acne and patient QOL, and there was no significant difference between them.

Efficacy of oral antibiotics on acne vulgaris and their effects on quality of life: A multicenter randomized controlled trial using minocycline, roxithromycin and faropenem

“…Concerns among acne patients are scarring, inflammatory and non‐IL; most patients are anxious to resolve the acne without leaving scars, and patients choose treatment for cosmetic reasons. It has also been reported that patients with acne suffer from low quality of life concerning emotional condition . Therefore, it is important to start appropriate treatment at an early stage to avoid the formation of IL and non‐IL and to prevent transition to nodules/cysts and scarring .…”

A placebo‐controlled, randomized, double‐blind, parallel‐group, comparative, multicenter study was conducted to investigate the efficacy and safety of benzoyl peroxide (BPO) gel, administrated once daily for 12 weeks to Japanese patients with acne vulgaris. Efficacy was evaluated by counting all inflammatory and non‐inflammatory lesions. Safety was evaluated based on adverse events, local skin tolerability scores and laboratory test values. All 609 subjects were randomly assigned to receive the study products (2.5% and 5% BPO and placebo), and 607 subjects were included in the full analysis set, 544 in the per protocol set and 609 in the safety analyses. The median rates of reduction from baseline to the last evaluation of the inflammatory lesion counts, the primary end‐point, in the 2.5% and 5% BPO groups were 72.7% and 75.0%, respectively, and were significantly higher than that in the placebo group (41.7%). No deaths or other serious adverse events were observed. The incidences of adverse events in the 2.5% and 5% BPO groups were 56.4% and 58.8%, respectively; a higher incidence than in the placebo group, but there was no obvious difference between the 2.5% and 5% BPO groups. All adverse events were mild or moderate in severity. Most adverse events did not lead to study product discontinuation. The results suggested that both 2.5% and 5% BPO are useful for the treatment of acne vulgaris.

“…Acne is known to have a major influence on patient QOL, and it has been reported that QOL deteriorates as the severity of symptoms increases. 2,14 However, to date, there have been no reports on the impact of acne scars per se on QOL. This study is the first to demonstrate that acne scars impair QOL, based on assessment using the DLQI (Fig.…”

Prevalence of scars and “mini‐scars”, and their impact on quality of life in Japanese patients with acne

There have been very few studies on the prevalence and severity of acne scars in Japanese patients. The aim of the present study was to investigate the prevalence of acne scars and their impact on the quality of life (QOL) in Japanese acne patients. Acne scars were classified as mini-scars (atrophic scars of ≥0.5 and <2 mm in diameter) atrophic scars (≥2 mm in diameter), and hypertrophic scars. The severity of acne and acne scars were evaluated. The background of patients and their QOL in relation to acne were assessed. Of 240 subjects, 218 (90.8%) had scars. All patients with scars had mini-scars; 61.2% and 14.2% of 240 had atrophic scars and hypertrophic scars, respectively. Severe scarring was found in patients who had experienced severe acne symptoms, although 15.0% of patients with scars had experienced only mild acne symptoms. The total Dermatology Life Quality Index score was significantly higher in patients with scars than in patients without scars (5.9 AE 4.4 vs 4.2 AE 4.1). Almost all the patients had small atrophic scars with a diameter of 0.5 or more and less than 2 mm, which we have termed "mini-scars". Acne scars had a negative impact on patient QOL. Early initiation of treatment is recommended to avoid acne scars.
