Abstract

Introduction: Malondialdehyde (MDA) is a useful determinant to show high level of lipid peroxidation which lead to impaired cell function. Previous studies have mentioned there is a relationship between high oxidative stress and low anti-oxidant activity in patients with oral lichen planus. The aim of this study was to evaluate serum level of Malondialdehyde as an indicator of oxidative stress in patients with oral lichen planus which is a chronic inflammatory disease with unknown etiology.

Materials & Methods: This descriptive-comparative study evaluated the oxidative stress status on twenty patients with oral lichen planus and 20 control healthy individuals based on serum level of Malondialdehyde.

Results: The mean serum Malondialdehyde levels in oral lichen planus patients and control individuals were 2.9 (±2) and 2.4 (±1.3) µg/ml, respectively, indicating no significant difference (P=0.6).

Conclusion: According to the results, role of Malondialdehyde in cellular damage and pathogenesis of oral lichen planus was not proved.

Keywords: Lichen planus, Malondialdehyde, Oxidative stress

Introduction

Oral lichen planus (OLP) is a common inflammatory disease with the prevalence of 0.5-2.2% in general population. In recent years, many studies have suggested the role of oxidative stress in the etiology of oral lichen planus as an autoimmune disease.[1] Noticeable increase of lipid peroxidation products and diminished antioxidant defensive system have been reported in patients with genital lichen planus. Effect of oxidative stress indices in pathophysiological changes occurring in basal cells of epidermis has also been pointed out.[2] Malondialdeid (MDA) has been considered as the main production of unsaturated fatty acids’ peroxidation which can be a sign of oxidative stress and has been defined as a suitable biomarker of endogenous DNA damage .[3,4]  The role of oxidative stress in the etiopathogenesis of oral lichen has been described by some researchers through estimating the levels of oxidative markers like MDA in various samples – serum, saliva and tissue. Studies by Rai et al. (2010) and Ergun et al. (2011) demonstrated the comparative analysis of serum MDA levels and saliva of the same group of patients in a therapeutic trial. [5, 6] Sander et al, performed a study on the samples of genital erosive lichen planus by immunohistochemistry method and reported higher MDA levels at epidermis and nearby dermal inflammatory infiltration in comparison with healthy controls and stated that this elevation is a sign of destruction of enzymatic anti-oxidative system in epiderm.[2] Most Previous studies in this field have been carried out on dermal and genital lichen planus.[7 ]Therefore, the aim of the current study was to evaluate the oxidative stress status with serum Malondialdehyde level in an Iranian population with OLP to detect the ethiopathogenesis of disease 

Material & Methods

In this descriptive-comparative study approved by ethics committee of Tabriz Medical University (No: 9166), twenty patients with OLP and twenty healthy persons as control group were homogenized in terms of age and entered into the study. The sample size was determined according to previous studies.[8] The whole study procedure was described to the patients and informed consent was obtained from the patients who entered into the study. A clinical diagnosis of OLP was established when reticular or popular textures were clinically present, and findings such as basal cell degeneration, infiltrations of inflammatory cells like T lymphocytes were observed histopathologically. The diagnosis of the keratotic lichen planus and erosive lichen planus was confirmed by the clinical features and clinicopathological features, respectively. Exclusion criteria were a) the presence of any stimulus leading to the lichenoid reactions including assumption of any medications, b) the appearance of the lesions near the amalgam restorations, c) the presence of any factors which could alter the equilibrium of production and elimination of free radicals; (such as cigarette smoking, alcohol consumption), d) the use of hydrogen peroxide mouth-rinse, having a diet full of fruit and vegetables, immunosuppressed patients, the use of antioxidant drugs (vitamin E and vitamin C), steroids, NSAIDS, and e) possible history of trauma or surgery during the last four weeks. Patients with systemic diseases, malignancies or dermal diseases, which would influence on the immune system.

After chart completion and necessary examinations, biopsy was done. Then, 5 cc blood samples were taken from both groups and after isolation of serum, sera samples were frozen and kept at 70°C for one month.  The test was done at laboratories of Tabriz Imam-Reza hospital.

In this test, the measurement of serum MDA level was carried out using Human MDA ELISA kit (Cusabio, USA) and ELISA apparatus (ELISA micro plate reader BIOTEK). The collected data were analyzed using Mann-Whitney U test in SPSS 16.  P<0.05 was considered statistically significant in this study.

Results

The mean age of lichen planus patients and control individuals was 34.1 and 35.6, respectively with no significant difference between the groups. 50 percent of Patients with oral lichen planus were female. The mean serum MDA levels in lichen planus patients and healthy individuals were 2.9 (2±) and 2.4µ 1.3± g/ml, respectively. It should be stated that MDA index mean was more in OLP patients than healthy individuals but this difference was  not statistically significant (P=0.6).

Discussion

In the current study, MDA index mean was more in OLP patients than healthy individuals but the difference was not statistically significant. Lipoperoxidation which results from the oxidation of membrane-associated polyunsaturated fatty acids of phospholipids has been considered a major presentation of oxidative stress .[3] MDA has been presumed as the main production of unsaturated fatty acids' peroxidation which can lead to reduction in cellular membrane permeability, devastating cellular structure and function which is incorporated in pathogenesis of most of disease .[2-4] MDA is addressed as a biomarker which is indicator of cellular destruction.[4] Oxidative stress has also been evaluated by other markers such as Serum Nitric Oxide in previous studies.[8]The findings of current study are different from some of the studies which evaluated the oxidative stress status in tissue specimen or salivary samples of patients with lichen planus. Different findings in these studies compared to the present study could be attributed to the different sample sources such as saliva and tissue samples in former studies and sera samples in current study.[4-6]Aly and Sezer conducted studies on 45 lichen planus patients and on  40 patients with LP  (None of the patients had the oral erosive variants of LP ),respectively. They concluded that the serum level of MDA was considerably increased.[7,9]In the study of Ergun et al., salivary and serum level of MDA and total anti-oxidative activity in 21 patients with oral lichen planus were investigated and it was revealed that there was a difference in comparison with healthy group.[6]The variants of LP were different in most of these studies. Few of the patients in Aly and Sezer's studies had OLP and none of them had erosive type but in the current study, patients only had OLP without cutaneous lesions.[7, 9] In the present study, only two forms of OLP were evaluated; therefore, the authors would suggest studying the problem of oxidative stress in different forms of OLP to confirm the opinion hypothesized on etiopathogenesis of the disease. And also as proposed by the reviewers it is suggested that different types of OLP to be discussed separately.Although the oxidative stress process is the cause of lichen planus is approved in many researches, findings regarding oxidative stress indices were not similar in these studies.[3,4] Unlike other studies, Agha-Hosseini et al. stated the oxidative stress processes role at OLP ethiopathogenesis and reported elevated level of salivary MDA in OLP as an index but TAC (total antioxidant capacity) was not different among lichen planus and healthy control. [10]

Conclusion

Although the role of MDA in the OLP cellular damage process was not approved in the current study, further studies with larger and different sources of samples are needed to evaluate this index and other oxidative stress indices in different forms of OLP, separately.
