Active clinical trials for "Lichen Planus"

The aim of this study is to evaluate salivary expression of lncRNA DQ786243 as a potential marker for diagnosis of oral potentially malignant lesions compared to normal controls and its effect on salivary expression of miRNA146a.

This study aims to develop a clinical database of patients presenting with vulvar complaints in order to comprehensively assess the presentation and current trends in management of vulvar disease.

Dental health professionals have a responsibility to perform routine intra- and extraoral inspection on their patients for detecting abnormalities. As dental hygienists (DH) and dentist (D) often see their patients on a regular basis, they have the opportunity to provide this screening, and at an early stage detect abnormalities.

Due to the change of life style, the incidence of oral cavity mucous membrane disease increased.In this study，been done a large number of pre-clinical practice and some experimental studies， based on the application of metabolomics technology to ultra-high liquid-mass spectrometry metabolomics analyzer as the core means， The metabolism of pattern recognition and combination of modern analytical techniques to measure blood and urine of patients with OLP-specific clearance of endogenous metabolites，and after the intervention of moss drink endogenous metabolites in the body as a whole group of. At the same time， the use of flow cytometry,，ELISA， immunohistochemistry and other modern technology, research OLP patients using clean moss drink before and after treatment of local lesions and peripheral blood CD4 +，CD8 + lymphocytes，Th1 cytokines (IFN-γ， TNF-α)， Th2 cytokines (IL-4，10) the dynamic changes. From metabolomics， cellular immunology， inflammation mechanism perspective of local OLP lesions， peripheral blood and changes in endogenous metabolites in the process,，in-depth study of traditional Chinese medicine to drink clean moss multi-component multi-target treatment of this disease mechanism， is widely used in traditional Chinese medicine treatment of OLP provide a theoretical basis for the promotion of Chinese medicine Qingxian Yin in the oral mucosal disease in the application， effectively solve clinical practice problems.

The molecular mechanisms of action of photo(chemo)therapy in skin diseases are investigated in this study. The phototherapeutic modalities employed include UVB (ultraviolet B), UVA (ultraviolet A), PUVA (psoralen+UVA) and/or extracorporeal photochemotherapy (photopheresis). The study will address whether and how photo(chemo)therapy affects specific biologic pathways in different skin disorders and search for predictive biomarkers.

To investigate the role of Vitamin D (VD) deficiency as a risk factor for the development and malignant transformation of Oral lichen planus (OLP) taking into consideration sex, dietary habits, sun exposure, socioeconomic status and psychological factors.

60 individuals were subdivided into 2 groups, 30 patients with oral lichen planus, 30 control individuals. Expression of miRNA-138 and cyclin D1 were evaluated in oral mucosa utilizing Quantitative real-time polymerase chain reaction and immunohistochemistry.

70 patients with suspicious oral lichen planus; atrophic and bullous erosive forms will be included. The blood samples will be drawn between 08:00 and 09:00 AM, after a fasting period of 12 hours, and analysis were performed within 2 hours of the sampling. The MPV and other hematologic parameters will be measured in a blood sample. A surgical biopsy will be performed for histopathological assessment.

Chronic erosive gingivitis is a syndrome (CEGS) that combines severe gingival inflammation and gingival erosion. The term "desquamative gingivitis" is often used in the literature to define chronic erosive gingivitis. However, this definition is inappropriate because the pathophysiological process at the origin of this gingival disease does not induce a desquamation but rather a loss of gingival substance, namely erosion, concerned wholly or in part of the gingival epithelium. In most clinical situations, chronic erosive gingivitis is an oral manifestation of a general disease with immune dysfunction. The most frequently described diseases are gingival lichen and autoimmune bullous diseases (AIBD). In 2018, as part of a monocentric study, we were the first to detail an original papillary gingival biopsy protocol, non-iatrogenic, perfectly suited to the anatomopathological examinations necessary for the diagnosis of AIBD gingival expression. The CEGS early detection by odontologists avoid delayed diagnosis and allows patients to be referred to the closest AIBD reference center. Hypothesis/Objective A bicentric study was conducted, to evaluate the clinical relevance of this protocol, including the differential diagnosis of the CEGS. Research was supplemented by carrying out a systematic review of the literature to compare the contributive capacity diagnostic of the papillary biopsy technique with other gingival sample methods (attached gingival tissue, mucosa). Method A retrospective bicentric observational study was conducted from October 2011 to July 2019, in two departments of oral medicine of two public hospitals in Paris (University Hospital - Bretonneau in Paris and Henri Mondor in Créteil; France). These two departments are specialized in the diagnosis and management of oral pathology; that of the Henri Mondor hospital is an AIBD reference center. The literature review was developed in accordance with PRISMA recommendations. It was conducted on Pubmed - MEDLINE and Cochrane Oral Health Group and included all existing publications from 1935 until August 2019. A manual search of publications from the unpublished literature was also conducted.

Oral lichen planus (OLP) is one of the most common mucosal diseases with autoimmune etio-pathogenesis with involvement of various cytokines similar to psoriasis.It generally occurs more commonly in females, in a ratio of 3:2. prolactin (PRL),It is a peptide hormone that has a role in autoimmune related diseases like systemic lupus erythematosus and , rheumatoid Artheritis. The role of PrL in OLP pathogenesis was never investigated.the aim of this study is to investigate the expression of PRL receptors in tissue biopsies of OLP patients.
