Depression, anxiety, and suicidal ideation should be considered by doctors when treating patients with AD. Because AD disease improvement appears to reduce these risks, this should be a priority.
Background Ocular surface diseases (OSDs), including conjunctivitis and blepharitis, are common in atopic dermatitis (AD) patients, but the magnitude and patient characteristics are unclear. Objectives To examine the prevalence of OSDs in adults with AD and identify patient characteristics and risk factors.Methods We designed a cross-sectional questionnaire-based survey and sent it via a secure public mail to all adult Danes with a hospital diagnosis of AD (ICD-10 code L20.x) registered in the National Patient Register (n = 16 718) between 2000 and 2019 and 7044 (42%) participated. Primary outcomes were OSDs and severity according to Ocular Surface Disease Index (OSDI). Adjusted odds ratios (aOR) were calculated with 95% confidence intervals (CIs) using logistic regression models. ResultsRespondents were mostly females and middle-aged (67.4%, mean [SD] age, 39.0 [15.5] years). Based on Patient-Oriented SCORing Atopic Dermatitis 49% had mild AD, 35% moderate, 10% severe and in 6% AD was inactive; 44.3% reported physician-diagnosed asthma bronchiale and 55.8% rhinitis. The lifetime prevalence of OSDs was 66.6% for conjunctivitis, 63.5% for hordeolum, 11.0% for blepharitis, 9.7% for keratitis, 2.0% for pterygium, 1.5% for symblepharon, 1.1% for keratoconus and 12.7% reported current conjunctivitis. Factors associated with lifetime occurrence of conjunctivitis included mild, moderate, and severe AD (aOR = 1.48 [95% CI, 1.02-2.14], aOR = 1.73 [95% CI, 1.19-2.53], aOR = 2.17 [95% CI, 1.42-3.21]), asthma bronchiale and rhinitis (aOR = 1.76 [95% CI, 1.49-2.07]), childhoodonset of AD (aOR = 1.34 [95% CI,) and systemic AD treatment (aOR = 1.27 [95% CI, 1.08-1.50]). Use of soft and hard contact lenses (aOR = 2.15 [95% CI, 1.65-2.80], aOR = 3.35 [95% CI, 1.62-6.92]) were associated with lifetime occurrence of keratitis. Moderate and severe AD, asthma bronchiale and rhinitis were also associated with a higher OSDI level.Conclusions This study identified important patient factors associated with OSDs. Clinicians should be attentive of ocular signs and symptoms in AD patients and ask about these.
IMPORTANCEFour distinct rosacea subtypes have traditionally been recognized, but the frequency of these subtypes among patients with rosacea remains unknown.OBJECTIVE To assess the frequency of 4 rosacea subtypes.DATA SOURCES This systemic review and meta-analysis included a search of 2 databases, PubMed and Embase, from inception of the databases to November 2, 2021. The search was filtered to include only studies of human participants published in English, French, and German.STUDY SELECTION Studies were screened independently by 2 of the authors and were included if they were original with a sample size of 25 or more patients and reported absolute numbers or frequency of patients affected by rosacea subtypes. Studies that did not report sufficient data to calculate the proportions of subtypes were excluded. DATA EXTRACTION AND SYNTHESISData extraction was performed independently and in duplicate by 2 of the authors, using the search term rosacea, according to the Preferred Reporting items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The search term, objectives, and study protocol methods were defined before the study was initiated. A total of 292 studies were included for full-text assessment. Owing to the heterogeneity of the included studies, a random-effects model was used. MAIN OUTCOME AND MEASURESThe main outcome was the proportion of patients with rosacea in each of the 4 major subtype groups defined by the 2002 National Rosacea Society classification system. Measures were absolute numbers or frequency of patients affected by each of the 4 rosacea subtypes.RESULTS A total of 39 studies examining 9190 patients with rosacea were included. The pooled proportion of erythematotelangiectatic rosacea was 56.7% (95% CI, 51.4%-62.0%), of papulopustular rosacea was 43.2% (95% CI, 38.8%-47.6%), of phymatous rosacea was 7.4% (95% CI, 6.1%-8.9%), and of ocular rosacea was 11.1% (95% CI, 6.7%-16.3%). Subtype distribution occurred equally among men and women except for phymatous rosacea, which was more prevalent in men. Studies from Africa showed the lowest proportion of erythematotelangiectatic rosacea. Differences in frequency of subtypes were observed when stratification by publication year was performed. CONCLUSION AND RELEVANCEIn this systematic review and meta-analysis, differences were found in rosacea subtypes by patient sex and by continent of origin and publication year of included studies. Erythematotelangiectatic and papulopustular rosacea were the most prevalent subtypes, but data should be interpreted with caution. Future studies should use the phenotype-based rosacea approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
