Staphylococcus aureus is frequently found in patients with atopic dermatitis (AD) and contributes to disease exacerbation. The objective of this study was to evaluate the efficacy and safety of bleach baths as an adjunctive treatment in AD patients. Patients between 2 and 30 years old with moderate to severe AD were enrolled in a prospective, randomized, placebo-controlled study. Patients soaked in diluted bleach or distilled water baths for 10 min, twice a week for 2 months. Efficacy assessments included the Eczema Area and Severity Index (EASI) scores and S. aureus density was determined using quantitative bacterial cultures. Patients in the treatment group showed significant reductions in EASI scores. A 41.9% reduction in S. aureus density from baseline was seen at 1 month further reducing to 53.3% at 2 months. Equal numbers of patients in both groups experienced mild side-effects. This study demonstrates that diluted bleach baths clinically improved AD in as little as 1 month. No patient withdrew from the treatment arm because of intolerance to the baths.

Introduction: Psoriasis vulgaris has a significant association with obstructive sleep apnoea (OSA). The study intended to explore the relation between the severity of psoriasis vulgaris and OSA risk, and to identify the factors that are attributed to increased risk of OSA. Methods: A cross sectional, observational study was carried out from October 2020 until April 2021 at the dermatology clinic of Hospital Tengku Ampuan Rahimah, Malaysia. All study participants were evaluated for OSA risk using the STOP-Bang and Epworth Sleepiness Scale questionnaires. Results: Our study recruited 237 participants and the results revealed a higher percentage of moderate to severe psoriasis participants with intermediate to high risk of OSA than participants with mild psoriasis (35.3% versus 17.7%, respectively). There was also a 2.3 times higher incidence of daytime sleepiness among participants with moderate to severe psoriasis as opposed to participants with mild psoriasis (44.1% versus 19.2%, respectively). We have also detected a significantly higher probability for OSA in psoriasis patients with diabetes mellitus versus those without (odds ratio: 2.09). We also noticed that for every unit rise in body mass index (BMI), there seemed to be a 1.06 times higher risk of OSA. Furthermore, patients with moderate to severe psoriasis were found to possess 3.32 times increased odds to have OSA. Conclusion: Our results suggest that psoriasis severity and the existence of comorbidities i.e. diabetes mellitus and high BMI are linked with an enhanced risk of OSA in adults with psoriasis.
