HOMA-IR Index and Pediatric Psoriasis Severity-A Retrospective Observational Study

Area of Science:

• Pediatric Dermatology
• Metabolic Syndrome
• Inflammatory Diseases

Background:

• Psoriasis is a chronic inflammatory condition with systemic implications.
• Insulin resistance is linked to adult psoriasis severity, but data in children is scarce.

Purpose of the Study:

• To investigate the association between insulin resistance (HOMA-IR) and psoriasis severity (PASI) in pediatric patients.
• To explore other potential relationships within the dataset.

Main Methods:

• Retrospective analysis of 43 children with various psoriasis types.
• Calculation of Homeostatic Model Assessment for Insulin Resistance (HOMA-IR).
• Assessment of Psoriasis Area and Severity Index (PASI) scores.

Main Results:

• No significant association was found between HOMA-IR and PASI (p=0.512).
• A potential link between nail pitting and insulin resistance was observed (p=0.038), but likely a false positive.
• Significant associations were noted between HOMA-IR and BMI (p=0.001), PASI and quality of life (p=0.005), and psoriasis severity and type (p=0.001).

Conclusions:

• The null hypothesis that insulin resistance is not positively associated with psoriasis severity in children cannot be rejected.
• Further studies are needed to confirm pilot findings on insulin resistance and pediatric psoriasis.
