Hypothyroidism is a common disease, and there may be a link between hypothyroidism and inflammatory skin disease. The purpose of this study is to assess whether hypothyroidism is more prevalent in psoriasis or rosacea patients. We utilized a large claims-based database to analyze rates of hypothyroidism in patients with psoriasis and rosacea compared to other patients with skin diseases. Participants were patients between 20-64 years of age with ICD-9 diagnosis codes for psoriasis, rosacea, and hypothyroidism. We found that rates of hypothyroidism in rosacea and psoriasis patients were similar to rates of hypothyroidism in those without rosacea or psoriasis.
