Risk of Developing Hypertension in Atopic Dermatitis Patients Receiving Long-term and Low-dose Cyclosporine: A Nationwide Population-based Cohort Study

BACKGROUND: Cyclosporine (CS) is a first-line immunosuppressive agent used to manage moderate to severe atopic dermatitis (AD). To date, the risk of developing hypertension associated with the long-term use of low-dose CS in AD patients is understudied. OBJECTIVE: To determine the cumulative dose-dependent effect of CS on the risk of developing hypertension in patients with AD. METHODS: A nationwide population-based retrospective cohort with 1,844,009 AD patients was built from the Korean National Health Insurance System database from 2005 to 2009. A Cox proportional-hazard regression analysis was performed according to patients\u27 CS treatment history adjusted for potential confounders. RESULTS: Current use of CS was associated with an increased risk of developing hypertension (adjusted hazard ratio, 4.442; 95% confidence interval, 3.761-5.247). Among the current CS users, a higher cumulative dose of CS (≥39,725 mg) or longer cumulative use of CS (≥182 days), was significantly associated with an increased risk of developing hypertension. CONCLUSION: The incidence of CS-associated hypertension is very low when using low-dose treatment regimens for AD. However, the current use or a high cumulative dose of CS for treating patients with AD increases the risk of developing hypertension. Precaution is needed when prescribing CS for long-term treatment of AD

Rosacea understanding among Korean patients: A multi-center questionnaire study

Background: Rosacea is a common chronic skin condition. To manage rosacea long-term and prevent further flare-ups, patients need to be aware of the disease and have sound knowledge of the condition. However, few related studies have been conducted on this subject. Objectives: The aim of this study was to identify rosacea awareness and knowledge among Korean rosacea patients and their means of gathering information on the disease. Methods: A prospective multicenter cross-sectional study recruited a total of 201 outpatients who were diagnosed with rosacea by a dermatologist. All were asked to complete a questionnaire asking about their demographic characteristics, rosacea awareness, and knowledge. Results: Among 201 rosacea patients, 146 (72.6%) were unaware of the disease before their diagnosis. The median number of questions the patients correctly answered was 6 of a total of 13 questions (46%) on rosacea knowledge, implying relatively shallow knowledge on rosacea. Better understanding of rosacea was negatively associated with age (odds ratio [OR] 0.965; 95% confidence interval [CI]: 0.941 – 0.989) and positively associated with a higher education level (OR = 2.896; 95% CI: 1.379–6.082). Individuals with rosacea felt that they were getting reliable information from doctors (n = 189, 94%), followed by the Internet (n = 38, 18.9%). Conclusion: Overall, rosacea awareness and knowledge among Korean rosacea patients were relatively low. Detailed education, especially targeting elderly patients and those with low education levels, is necessary for better disease outcomes
