Insulin Resistance and Metabolic Syndrome in Patients with Seborrheic Dermatitis: A Case-Control Study

Area of Science:

• Dermatology
• Endocrinology
• Metabolic Health

Background:

• Seborrheic dermatitis (SD) is a chronic inflammatory skin disease with incompletely understood systemic effects.
• Limited knowledge exists regarding the association between SD and metabolic syndrome (MS) or glucose metabolism disorders.

Purpose of the Study:

• To investigate the prevalence of metabolic syndrome (MS) and glucose metabolism disorders in patients diagnosed with seborrheic dermatitis (SD).
• To evaluate potential links between SD and conditions like insulin resistance and impaired glucose metabolism.

Main Methods:

• A case-control study involving 53 adult patients with SD and 50 matched healthy controls.
• Assessment of demographic data, anthropometrics, blood pressure, family history, smoking status, and disease severity.
• Determination of fasting plasma glucose, insulin, HbA1c, lipid profiles, OGTT 2-h PG, HOMA-IR, and presence of MS.

Main Results:

• The SD group exhibited significantly higher weight, waist circumference, family history of SD/metabolic disorders, and smoking rates compared to controls.
• Elevated fasting plasma insulin, triglyceride levels, HOMA-IR, and OGTT 2-h PG were observed in the SD group.
• A significantly higher prevalence of insulin resistance was found in patients with SD (58.49%) versus controls (22%).

Conclusions:

• Findings suggest a significant association between seborrheic dermatitis and insulin resistance, potentially linked by shared inflammatory pathways.
• SD patients may have increased susceptibility to diabetes; monitoring for insulin resistance complications and promoting healthy lifestyles are advised.
