Background: Lichen planus (LP) is animmune mediated inflammatorydiseaseof skin and
mucous membranes without a clear etiology. Interleukin-6 (IL-6) is a pro-inflammatory
cytokinewith variousbiologicaland pathological impactson immunity, acute phase response
andinflammation. ExcessiveIL-6production can play a role in the pathogenesis of several
pathological conditionslike psoriasis.
Aim:This study aimed to evaluate serum IL-6 levels inLP patients alongwithassessment
ofitscorrelation with disease severity.
Patients and methods: Twenty-one adult patients with LP as well astwenty-one healthy adult
controls were enrolled in the study. The total score of LP severity was estimated for all
patientsby calculation of the affected body surface area in cutaneous LP patients and clinical
scoring system with visual analogue scale for pain assessment for oral LP.Serum IL-6 levels
were measured in all participants using enzyme-linked immunosorbent assay.
Results:The mean serumIL-6 levels were significantly higher in patients than controls (P <
.002). A positive correlation wasnoticed between serum IL-6 with both cutaneous LP (P
<0.004) and oral LP (P <0.005) severities.

Background: Lichen planus (LP) is a common disorder whose etiopathogenesis is not clear.Recently, it has been suggested that increased reactive oxygen species (ROS) play important roles in the underlying mechanism of LP. Free radicals have an important involvement in the underlying mechanism of lichen planus and also various skin diseases. The aim of the study was to evaluate serum uric acid (UA) levels as a measure of the antioxidant defense status in lichen planus patients.
Methods: A case control study was performed on 17 patients with lichen planus and 17 healthy subjects as a control group. We estimated Serum level of uric acid and ascorbic acid using ELISA.
Results: The mean of serum levels of uric acid and ascorbic acid was lower in patient group compared to healthy group with no significant difference between the two studied groups.
Conclusion: Lichen planus pathogens are not specifically affected by antioxidants as uric acid and ascorbic acid. However, in addition to other interactive variables, the difference in the level of serum for these anti-oxidants between lichen planus patients and healthy subjectsalbight not important– may suggest their involvement.

Lichen planus is an autoimmune disorder that primarily affects the body's skin and
multiple mucous membranes. In multicellular species, protein 53 and syndecan-1protein
play an significant role since they control the cell cycle and thus play a major role in
tumor suppression and cancer prevention. The p53 gene was therefore identified as a
"genome protector," referring to its role in preserving the integrity of genetic
information by preventing gene mutations. The purpose of this analysis was to study the
association between certain immune markers in lichen planus patients.
The aim of this study : Study correlation between some immune marker in patients with
lichen planus
Methods 'Thirty formalin-fixed , paraffin-embedded tissue pieces, diagnosed as Oral
Lichen planus(OLP), were included in the sample of this report.
Results: Evaluation of P53 Immunohistochemistry and Evaluation of syndecan-
1protein Immunohistochemistry Conclusion: the marker p53 expression is high in the
patient with Lichen Planus while the second studed marker syndecan-1 protein is less
than marker p53

Introduction: Lichen planus, is a chronic autoimmune, mucocutaneous disease affecting the oral mucosa besides the skin, genital mucosa, scalp and nails.The exact etiology of oral lichen planus is unknown. The disease most commonly affects middle-aged females. Oral lichen planus usually presents as white striations (Wickham's striae), white papules, white plaque, atrophic , ulcerative, erosive or as blisters. There is a well established correlation between oral lichen planus and liver disease. Opinion amongst researchers vary on terminology of lichen planus and lichenoid drug reaction . Recent literature reported association between lichen planus and thyroid disease.
Aim: The main aim of this study is to evaluate the association between oral lichen planus and thyroid disease and its prevalence amongst patients visiting our dental institute.
Materials and methods: 67 case sheets of patients, diagnosed with oral lichen planus between June 2019 and March-2020 were retrieved from the electronic database . Collected data were entered into the Excel sheet and was analysed using SPSS analysis.
Results: Results showed a positive association between oral lichen planus and thyroid disease, mainly hypothyroidism (7.46%). Females were more affected than males (53.7%).The erosive variant of oral lichen planus was more prevalent among the study population (44.7%). There was a positive correlation between predominant clinical variety of Lichen planus and site involved. The positive correlation between hypothroid state and lichen planus is also reported.
Conclusion: In conclusion, our study establishes an association between oral lichen planus and a coexisting thyroid disorder mainly hypothyroidism .
