Dyslipidemia in Lichen Planus: A Case-control Study.

Lichen planus (LP) is a chronic inflammatory disease that affects the skin, mucous membranes, scalp and nails. It has been reported that diabetes mellitus and dyslipidemia prevalence were higher in patients with LP. However, most of these reports were retrospective, database search, which included patients who were on lipid-lowering drugs. This study aims to conduct a prospective case-control study to investigate the association between LP and dyslipidemia.Methods: This study was conducted on 49 patients with LP (mucosal or cutaneous) and 99 healthy controls. All patients were subjected to clinical and histological examination, whereas controls were subjected to clinical examination. The variables analyzed were age, sex, tobacco consumption, hypertension, lipid profiles and fasting blood glucose.Results: Serum levels of triglycerides, total cholesterol and LDL cholesterol were higher in patients with LP. However, there was no significant difference between patients with LP and controls. No significant differences between LP patients and controls were observed with the average age, sex, tobacco consumption and hypertension.Conclusion: This prospective case-control study demonstrated that dyslipidemia was more common among patients with LP. Physicians should be aware of this association and consider screening them for dyslipidemia.
