Dyslipidemia in Lichen Planus: A Case-control Study

Area of Science:

• Dermatology
• Cardiovascular Health
• Metabolic Disorders

Background:

• Lichen planus (LP) is a chronic inflammatory condition affecting skin, mucous membranes, scalp, and nails.
• Previous studies suggest a link between LP and higher prevalence of diabetes mellitus and dyslipidemia.
• Existing research is largely retrospective and includes patients on lipid-lowering medications, necessitating further investigation.

Purpose of the Study:

• To prospectively investigate the association between lichen planus and dyslipidemia.
• To compare lipid profiles and other metabolic factors in LP patients versus healthy controls.

Main Methods:

• A prospective case-control study involving 49 patients with lichen planus (LP) and 99 healthy controls.
• Clinical and histological examinations for LP patients; clinical examinations for controls.
• Analysis of variables including age, sex, tobacco use, hypertension, lipid profiles, and fasting blood glucose.

Main Results:

• Patients with lichen planus exhibited higher serum levels of triglycerides, total cholesterol, and LDL cholesterol compared to controls.
• No significant differences were observed in age, sex, tobacco consumption, or hypertension between the LP group and the control group.

Conclusions:

• Dyslipidemia is more prevalent in patients diagnosed with lichen planus.
• Physicians should maintain awareness of this association and consider routine screening for dyslipidemia in patients with LP.
