[Lichen ruber and diabetes mellitus--pathogenetic relations?]

Area of Science:

• Endocrinology
• Dermatology

Context:

• Oral lichen planus (OLP) is a chronic inflammatory condition with debated etiologies.
• Metabolic syndrome components, such as hyperglycemia and hypercholesterolemia, are increasingly recognized as potential influencing factors in various inflammatory diseases.

Purpose:

• To investigate the prevalence of specific laboratory parameters, including glucose tolerance and lipid profiles, in patients with oral lichen ruber planus compared to a healthy control group.
• To explore a potential pathogenetic relationship between oral lichen ruber planus and conditions like diabetes mellitus.

Summary:

• A prospective study of 177 oral lichen ruber planus patients and 177 controls revealed significantly higher incidences of abnormal glucose tolerance (30.1% vs. 11.9%) and elevated serum cholesterol (35.5% vs. 17.5%) in the patient group.
• The co-occurrence of hyperglycemia and hypercholesterolemia was also markedly more frequent in OLP patients (11.9% vs. 1.7%).
• Similar metabolic differences were observed in patients with exclusive skin involvement, suggesting a systemic association.

Impact:

• These findings indicate a potential association between oral lichen ruber planus and metabolic dysregulation, particularly hyperglycemia and hypercholesterolemia.
• The results may prompt further research into the role of metabolic factors in the pathogenesis of lichen ruber planus.
• Clinicians should consider screening OLP patients for metabolic abnormalities, potentially improving patient management and outcomes.
