Atopic dermatitis (AD) is a complex disease with varying degrees of itch, pain, eczematous skin lesions and quality of life impact. Research over the past decade uncovered myriad associations of AD with comorbid health disorders. There are well-established associations of AD with atopic comorbidities in children and adults, including asthma, hay fever, food allergies and less commonly eosinophilic esophagitis. AD is also associated with higher rates of mental health disorders, including depression, anxiety and attention deficit (hyperactivity) disorder.
AD patients also have multiple risk factors for hypertension, including chronic sleep deprivation and limitations on physical activity from itch. Yousaf et al conducted a systematic literature review and meta-analysis of 19 studies and found significantly increased likelihood of hypertension in patients with AD compared to healthy controls, particularly moderate-to-severe AD. Though, the odds of hypertension were lower in patients with AD compared to psoriasis.
Sleep disturbances (SD) are also common in AD patients. Manjunath et al conducted a cross-sectional, dermatology practice-based study to examine clinical differences in geriatric vs younger adult AD patients. Geriatric age was not associated with any significant differences of AD severity. However, geriatric AD patients had significantly more nights of SD, particularly trouble staying asleep, and increased fatigue than younger adults. In general, having good sleep hygiene and getting adequate sleep are important for overall health and longevity. SD therefore warrant particular attention in clinical management of AD as they are often modifiable with improved AD control.
Likewise, the myriad comorbidities associated with AD may lead to poorer health outcomes, such as hospitalization. Edigin et al conducted a longitudinal study of 23,410 adults hospitalized in the United States with AD. Hospitalizations rates increased between 1998 and 2018 owing to comorbid health disorders, but not AD itself.
Together, these results highlight the importance of holistic management of AD patients, including atopic and non-atopic comorbidities. However, many questions remain about how and when to best screen for various comorbidities. Generally, more severe AD is one of the strongest predictors of atopic and mental health comorbidities, as well as sleep disturbances and hypertension as shown in the abovementioned studies. Additionally, geriatric AD patients warrant closer monitoring of SD. Of course, screening patients for these comorbidities can take up precious time in a busy clinical practice. Though, it is a worthwhile investment of time and will improve patients’ health outcomes and the quality of care you provide for patients.
