Evaluation of Hepatitis B Vaccination among Lichen Planus Patients.
Lichen planus (LP) is an idiopathic chronic inflammatory mucocutaneous disease. Many reports in the literature have described hepatitis B vaccine as a predisposing factor for LP. This study was performed to determine the rate of previous vaccination against hepatitis B in LP patients. This was a cross sectional study on LP patients. Diagnosis of LP was confirmed by histological examination. Data were gathered by dermatology residents based on a checklist designed to guide their interview. Blood samples were tested for HBsAB titer, HBsAg, HCV Ab and liver function tests. One hundred & twenty four (124) patients entered the study. Females were 2.72 times more affected. The mean age of patients was 45.63 years (age range; 18-88). Forty-four (35.5%) patients had been vaccinated against hepatitis B. Lichen planus during the first six months of vaccination occurred in only one patient. Our findings bring into question the causative role of HBV vaccine in LP incidence in our population.
