Controversial cardiovascular and hematologic comorbidities in atopic dermatitis

Area of Science:

• Dermatology
• Cardiology
• Hematology

Background:

• Atopic dermatitis (AD) has wide-reaching systemic involvement.
• Cardiovascular and hematological comorbidities associated with AD present a significant economic and physical burden.
• Existing data on the association between these comorbidities and AD is controversial.

Purpose of the Study:

• To review cardiovascular and hematological comorbidities in AD patients.
• To detail conflicting evidence, pathophysiology, and medication links.
• To clarify the association between AD and its systemic comorbidities.

Main Methods:

• Conducted a PubMed search for studies on AD and cardiovascular/hematological comorbidities (approx. 30 results).
• Performed additional searches for studies on pathophysiology and medication connections.
• Analyzed existing literature to identify associations and attributable risks.

Main Results:

• Conflicting associations found between AD and hypertension, stroke, myocardial infarction, heart failure, and thrombosis.
• Consistent positive associations observed for coronary heart disease, angina, peripheral artery disease, and anemia.
• Low attributable risks for stroke, myocardial infarction, heart failure, and atrial fibrillation in AD patients.

Conclusions:

• The pathophysiology underlying AD's systemic comorbidities remains unclear.
• Medications used for AD (corticosteroids, cyclosporine, antimetabolites) may be linked to comorbidities.
• Controversial associations complicate screening recommendations and management, necessitating further understanding to reduce patient burden.
