Clinical and Molecular Correlates of Response to First Line Treatment in Lichen Planus

Sponsor: University of Aberdeen

Summary

Lichen planus is a common inflammatory (swelling and pain of tissue) disease in the general population that affects mostly the mouth although skin and genital areas can also be affected. It can cause considerable discomfort during activities such as eating, talking and tooth brushing and may impair sexual function with an overall deleterious impact on quality of life. There is also increased evidence of cancer in a subtype of lichen planus. Therefore, treatment is essential in these patients to control the symptoms and improve the quality of life. Locally applied steroids are the first line medicines used in the treatment of patients with lichen planus. This medicine can only control the symptoms, but cannot cure the disease. In addition, this treatment cannot be effective in all patients with lichen planus. This may be attributed to differences in host factors, mouth bacteria and individual host responses to bacteria. The exact cause of this disease is also unknown. New studies have shown changes in the balance of mouth bacteria and host responses to bacteria in patients with lichen planus. So the main purpose of our study is to identify clinical(age, gender, related medical conditions, oral health and the presence of deleterious habits like smoking and alcohol consumption), molecular(analysis of oral microbes and immune markers) and histological factors (change within tissue) associated with poor response in lichen planus patients undergoing treatment with locally applied steroid medicines. Overall, knowledge of these factors associated with disease progression is sparse, which limits progress in the realm of development of novel and personalised treatment strategies. In this study, we explore the individual and combined role of different markers in lichen planus for improving diagnosis, predicting disease progression and treatment effectiveness.
