Filter by:Acne scar is a common complication of acne vulgaris (AV). Early and effective treatment of AV has a crucial role in managing both acne and acne scarring. Oral isotretinoin (OI) is a widely preferred agent in treating moderate and severe AV worldwide. It has been shown that topical retinoids can also be effective in the treatment of atrophic acne scars. However, there is no study in the literature evaluating the effectiveness of OI protocol on atrophic scars with objective data. With the developing sonoelastography technology in recent years, a quantitative, objective, and reliable examination of the elasticity of the skin and subcutaneous tissue can be provided. In this study, for a detailed and objective evaluation of the effects of OI on atrophic acne scars, we investigate the AV severity, atrophic scar grade, scar size (SS), dermis and subcutaneous tissue thickness (STT), and changes in scar and subcutaneous tissue elastic modulus (EM) in moderate and severe AV patients with atrophic acne scars by clinical observation and SWE. Materials and Methods: It was designed as a single-center, prospective and observational study. Ethics committee approval was obtained. Thirty patients who applied to the Istanbul Training and Research Hospital, Dermatology Department, between November 2021 and January 2022 diagnosed with moderate and severe AV accompanied by atrophic acne scars were included in the study. Demographic characteristics of the patients were recorded. We started the OI with a standard dose regime. On days 0 and 90 of treatment, each patient's AV and scar severity; were evaluated with the global acne grading system (GAGS) and the Goodman and Baron Qualitative Global Scar Rating System (GSRS). On the same days, the dermal thickness (DT), STT, SS, scar, and subcutaneous tissue EM on the right and left cheeks were measured by the same experienced radiologist with SWE. Appropriate statistical methods analyzed the results.
The nail is an important skin appendage which can provide information about the person's overall health status in addition to having several important functions such as protection, tactile sensation, grasping. Many nail abnormalities which can have considerable psychological impact are side effects of drug administration. Retinoids have various effects on nails. Although isotretinoin as a retinoid has been associated with both decreased and increased nail growth, the great majority of such associations are not evidence-based. So, it was aimed to investigate the effects of isotretinoin on morphology, growth rate, and thickness of the nail plate.
The goal of this study is to enroll 250 participants that have joined the MURDOCK Study Horizon 1.5 (Duke IRB Pro00011196) with a current or prior diagnosis of severe acne AND current or prior treatment with oral isotretinoin. All 250 participants will answer a 5-page questionnaire designed to collect information on the diagnosis of severe acne and response to oral isotretinoin treatment. The aim is to identify genetic predictors of severe acne vulgaris and the outcome of oral isotretinoin treatment.
