Adult Atopic Dermatitis with Comorbid Atopic Disease is Associated with Increased Risk of Infections: A Population-Based Cross-Sectional Study.

ABSTRACT:

Introduction

Atopic dermatitis (AD) is related to other atopic diseases asthma and allergic rhinitis. It is known that those with asthma or allergic rhinitis have impaired immune responses that may predispose them to infections. This study sought to determine whether adult AD is associated with systemic infections, and whether association is strengthened in those with AD plus another atopic disease.

Methods

This cross-sectional study obtained information from adults in the 2010 and the 2012 National Health Interview Survey (NHIS). The primary exposure was history of AD without or with an additional atopic disease, asthma or allergic rhinitis. Self-reported systemic infections were the primary outcomes. Survey logistic regression was performed and adjusted odds ratios (aOR) reported.

Results

AD in NHIS 2010 was associated with increased risk of sinusitis [aOR (95% CIs): 1.65 (1.42, 1.91), P < 0.001], head or chest cold [1.31 (1.12, 1.52), P < 0.001], and gastrointestinal illness [2.39 (1.97, 2.89), P < 0.001], and in NHIS 2012, pneumonia/influenza [1.73 (1.54, 1.95), P < 0.001], strep throat/tonsillitis [1.72 (1.54, 1.92), P < 0.001], sinusitis [1.77 (1.54, 2.02), P < 0.001], head or chest cold [1.49 (1.33, 1.67), P < 0.001], and infectious disease [2.66 (2.20, 3.21), P < 0.001]. An increase in atopic disease mirrored an increase in number of infectious outcomes and was statistically significant in the combined dataset (P < 0.001).

Conclusion

The associations between AD and AD plus another atopic disease with systemic infections suggest that an underlying immune defect may be contributing to microbial susceptibility. Further studies are warranted to understand the burden of infectious disease in this population.

Project description:ObjectiveDescribe the pattern of atopic disease prevalence from infancy to adulthood.DesignCross-sectional household survey.SettingCommunity-based demographic surveillance site, Mirzapur, Bangladesh.Participants7275 individuals in randomly selected clusters within 156 villages.Primary and secondary outcome measuresThe 12-month prevalence of atopic dermatitis (by UK Working Party Criteria (UK criteria) and International Study of Asthma and Allergies in Childhood (ISAAC)), asthma and rhinitis (by ISAAC); disease severity (by ISAAC); history of ever receiving a medical diagnosis.ResultsChildren aged 2 years had the highest prevalence of atopic dermatitis-18.8% (95% CI 15.2% to 22.4%) by UK criteria and 14.9% (95% CI 11.6% to 18.1%) by ISAAC- and asthma (20.1%, 95% CI 16.4% to 23.8%). Prevalence of rhinitis was highest among 25-29 year olds (6.0%, (95% CI% 4.5 to 7.4%). History of a medical diagnosis was lowest for atopic dermatitis (4.0%) and highest for rhinitis (27.3%) and was significantly associated with severe disease compared with those without severe disease for all three conditions (atopic dermatitis: 30.0% vs 11.7%, p=0.015; asthma; 85.0% vs 60.4%, p<0.001; rhinitis: 34.2% vs 7.3%, p<0.001) and having a higher asset-based wealth score for asthma (29.7% (highest quintile) vs 7.5% (lowest quintile), p<0.001) and rhinitis (39.8% vs 12.5%, p=0.003). Prevalence of having >1 condition was highest (36.2%) at 2 years and decreased with age. Having atopic dermatitis (ISAAC) was associated with significantly increased odds ratios (OR) for comorbid asthma (OR 5.56 (95% CI 4.26 to 7.26)] and rhinitis (3.68 (95% CI 2.73 to 4.96)). Asthma and rhinitis were also strongly associated with each other (OR 8.39 (95% CI 6.48 to 10.86)).ConclusionsAtopic disease burden was high in this rural Bangladeshi population. Having one atopic condition was significantly associated with the presence of another. Low incidence of ever obtaining a medical diagnosis highlights an important opportunity to increase availability of affordable diagnosis and treatment options for all age groups.
