Filter by:Oral lichen planus (OLP) is a chronic inflammatory disorder which causes local irritation,discomfort and subsequent poor dentition and discomfort in eating . Various treatments have been suggested for OLP but their results are unsatisfactory .Despite the fact that steroids have been the main therapeutic choice for many years,some researches have been done regarding the efficacy of other medication such as metronidazole and doxycycline.The purpose of this study is to determine whether metronidazole and doxycycline are effective in the treatment of oral lichen planus and to compare their efficacy with each other.
The purpose is to determine the extent of genetic damage in oral mucosal lesions ascertained in the study, whether specific genotypes are associated with genetic damage observed in the oral mucosal lesions, whether the extent of genetic damage changes over time, and what factors (e.g. smoking) contribute to those changes. Genetic damage indicators will include among others DNA adduct formation, particularly related to tobacco smoke carcinogens such as polycyclic aromatic hydocarbons. The genotypes of interest will be focused on these affecting carcinogen metabolism, (e.g., (CYP family), but may also include those related to growth factors, cell cycle control, and DNA repair. Microsatellite instability is another key indicator of damage that we plan to examine. This study was undertaken due to the paucity of data on the types of oral lesions seen in general dental practice and the limited knowledge of the natural history of these lesions. Persons were enrolled who had red and/or white oral lesions identified at 6 Dental Clinics at VA Medical Centers. The VA Centers involved were: Washington, DC; Atlanta, GA; Durham, NC; San Francisco, CA; Danville, IL; and San Antonio, TX. When a dentist found a red or white lesions in the course of routine outpatient examinations and care, obvious causes such as denture frictional lesions could be ruled out, and the normal standard of care for the lesion was biopsy, the patient was considered for enrollment into the study. The study was described to the patient, the consent for was signed, the patient received an intraoral examination to identify and characterize the oral lesions, the lesions were photographed, an oral epithelial cell sample was taken from the site and from the rest of the oral mucosa, and the patient was interviewed using a standard questionnaire that requested information about sociodemograhic, medical, and lifestyle factors, particularly tobacco and alcohol use all as part of the study protocol, and the patient received a biopsy as part of normal care. The biopsy report was obtained as was a small piece of the biopsy material that was not needed for patient diagnostic purposes. The subjects returned every 4-6 months for reassessment of the lesion or to determine that the lesion had not returned. The patients completed a questionnaire at each of these visits so that lifestyle factors such as tobacco and alcohol use could be reassessed. Also oral epithelial cell scrapings were obtained at each of these visits. This study is particularly valuable because longitudinal data was collected and because the data were collected over time using standard procedures.
Background and hypothesis. Oral erosive lichen planus (OELP) is a severe form of mucosal lichen planus. Lesions often induce intense pain and limit feeding. Its course is chronic with flares and spontaneous remissions are rare. Treatment is difficult: topical steroids are usually used first but antimalarials, oral retinoids, systemic steroids, immunosuppressive drugs and even extracorporeal photochemotherapy can be necessary for treating severe forms. The need for novel therapies with less morbidity is obvious. Calcineurin inhibitors have a theoretical interest in treating OELP: this has been emphasized by several open studies performed with topical tacrolimus. The effectiveness of 1% pimecrolimus cream has been suggested by a few case reports and by one recent comparative study which confirmed the potential interest of topical pimecrolimus in treating OELP. The absorption of pimecrolimus through human mucosa is still unknown. Its application on ulcerative lesions such as OELP ones, could lead to significant systemic levels of the molecule. Objective: To evaluate the efficacy of 1% pimecrolimus cream in treating oral erosive lichen planus (OELP) and to assess its tolerance.
Study investigating the use of pimecrolimus 1% cream for oral lichen planus
The purpose is to assess the response of subjects to etanercept (as compared to placebo) in treating the physical signs of mucosal and cutaneous lichen planus. The investigators also wish to assess the effect of etanercept on disease-related itching, pain, and serious adverse events in patients with lichen planus.
The purpose of this study is to determine whether curcuminoids are effective in the treatment of oral lichen planus.
The purpose of this study is to find out how safe and effective an investigational drug called alefacept (amevive) is for the treatment of moderate to severe erosive mucosal lichen planus. Lichen planus is a skin disease that can last a long time and cause significant pain, itching, and scarring. It can affect the mucous membranes (area inside the mouth and vagina) and these areas can become erosive (sores can develop). Currently there is no known cure for this disease. An investigational drug is one that has not been approved by the United States (US) Food and Drug Administration (FDA) to treat a particular condition or disease. Alefacept has been approved to treat psoriasis (a scaly skin rash). A number of reports suggest that lichen planus develops for some of the same reasons as psoriasis, but alefacept is not yet approved for the treatment of psoriasis.
This study is to determine whether efalizumab 1.0mg/kg given by subcutaneous injection for 12 weeks is effective in treating oral lichen planus. This is a 20 week, single center, open-label pilot study to enroll 5 subjects.
The purpose of this study is to investigate whether topical applied pimecrolimus will lead to improvement of erosive oral lichen planus. This effect will be monitored by reduction of erosive mucosal area and reduction of patient's pain symptoms.
This study will evaluate the effectiveness of dexamethasone 0.01% solution in treating pain associated with oral lichen planus, a chronic disease that causes painful ulcers inside the mouth. The cause of lichen planus not known, but it may be related to an allergic or immune reaction. This study will examine what causes the disease, the pain associated with it, its impact on patients' lives and the use of dexamethasone to treat it. Patients 12 or older with severe oral lichen planus may be eligible for this study. Candidates are screened with blood tests and a biopsy to confirm the diagnosis and provide tissues for research purposes. For the biopsy, two small circles of tissue, each about 4 mm (1/5 inch) across, are surgically removed. Participants are randomly assigned to rinse their mouth with either a dexamethasone solution or placebo (a rinse with no active ingredient) four times a day for 4 weeks. During this period they may not use any oral or topical pain or anti-inflammatory medications except diphenhydramine 12.5 mg/5 ml (a topical numbing medicine) and Tylenol, both which are provided by the study. Patients come to the NIH Clinical Center for three 1-hour visits (once every two weeks) and once more 4 weeks after the study medications are stopped. At the first three visits patients submit a pain diary in which they have recorded information on pain levels, and they are checked for any medication side effects. On the third visit (the last day they take the study drug) they are also tested for adrenal suppression that may have resulted from taking the steroid rinse. For this test they are given an injection of a drug called synacthen and after 1 hour, a blood sample is drawn. Patients return for a final visit 1 month later to determine if their disease returns or improves after the medication is stopped.
