Impact of Oral Lichen Planus on Oral Health-Related Quality of Life: A Systematic Review and Meta-Analysis

Upregulation of psoriasin/S100A7 correlates with clinical severity in patients with oral lichen planus

OBJECTIVES

The aim of this study was to: (1) investigate the expression patterns of antimicrobial peptides (AMPs), specifically psoriasin (S100A7) and calgranulin A and B (S100A8/A9), in patients with oral lichen planus (OLP) compared to healthy individuals; (2) evaluate the oral health-related quality of life (OHrQoL) in OLP patients versus healthy controls; (3) investigate the impact of clinical severity of OLP on OHrQoL; and (4) assess the influence of AMP expression on clinical severity and OHrQoL in OLP patients.

MATERIALS AND METHODS

Oral mucosal biopsies (n = 38) were collected from healthy individuals (n = 17) and patients with OLP (n = 21). Levels of AMPs (S100A7, S100A8, S100A9) and pro-inflammatory cytokines interleukin-8 (IL-8) and tumor necrosis factor alpha (TNFα) were assessed by RT-qPCR. AMP protein localization was identified by indirect immunofluorescence analysis. OHrQoL was assessed using the OHIP-G14 questionnaire, and clinical severity was evaluated with the Oral Disease Severity Score (ODSS). Correlations between OLP manifestation, OHrQoL, and AMP expression were evaluated.

RESULTS

(1) S100A7 (p < 0.001), IL-8 (p < 0.001), and TNFα (p < 0.001) mRNA levels were significantly upregulated in OLP tissue compared to healthy tissue, while S100A8 (p < 0.001) and S100A9 (p < 0.001) mRNA levels were downregulated. Immunofluorescence staining revealed an enhanced expression of S100A7 and decreased protein expression of S100A9 in OLP tissue. (2) OLP patients (9.58 ± 8.32) reported significantly higher OHIP-G14 scores compared to healthy individuals (0.67 ± 0.87; p < 0.001), particularly in the categories "physical pain" (p < 0.001) and "psychological discomfort" (p = 0.025). (3,4) Clinical severity (25.21 ± 9.77) of OLP correlated positively with OHrQoL (ρ = 0.497) and psoriasin expression (ρ = 0.402).

CONCLUSIONS

This study demonstrated differential expression patterns of AMPs in OLP and highlighted the correlation between the clinical manifestation of OLP and OHrQoL. Further research approaches should address the role of psoriasin in the risk of malignant transformation of OLP.

CLINICAL RELEVANCE

Psoriasin is a putative biomarker to monitor disease severity including malignant transformation of OLP lesions. OHIP-G14 scores can be useful to monitor OHrQoL in OLP patients.

The relationship between clinical symptoms of oral lichen planus and quality of life related to oral health

INTRODUCTION

Oral Lichen Planus (OLP) is a chronic and relatively common mucocutaneous disease that often affects the oral mucosa. Although, OLP is generally not life-threatening, its consequences can significantly impact the quality of life in physical, psychological, and social aspects. Therefore, the aim of this research is to investigate the relationship between clinical symptoms of OLP and oral health-related quality of life in patients using the OHIP-14 (Oral Health Impact Profile-14) questionnaire.

MATERIALS AND METHODS

This descriptive-analytical study has a cross-sectional design, with case-control comparison. In this study, 56 individuals were examined as cases, and 68 individuals were included as controls. After recording demographic characteristics and clinical features by reviewing patients' records, the OHIP-14 questionnaire including clinical severity of lesions assessed using the Thongprasom scoring system, and pain assessed by the Visual Analog Scale (VAS) were completed. The ADD (Additive) and SC (Simple Count) methods were used for scoring, and data analysis was performed using the T-test, Mann-Whitney U test, Chi-Square, Spearman's Correlation Coefficient, and SPSS 24.

RESULTS

Nearly all patients (50 individuals, 89.3%) reported having pain, although the average pain intensity was mostly mild. This disease has affected the quality of life in 82% of the patients (46 individuals). The patient group, in comparison to the control group, significantly expressed a lower quality of life in terms of functional limitations and physical disability. There was a statistically significant positive correlation between clinical symptoms of OLP, gender, location (palate), and clinical presentation type (erosive, reticular, and bullous) of OLP lesions with OHIP-14 scores, although the number or bilaterality of lesions and patient age did not have any significant correlation with pain or OHIP scores.

CONCLUSION

It appears that certain aspects of oral health-related quality of life decrease in patients with OLP, and that of the OLP patient group is significantly lower in terms of functional limitations and physical disability compared to the control group. Additionally, there was a significant correlation between clinical symptoms of OLP and pain as well as OHIP scores.

Oral lichen planus and lichenoid lesions - challenges and pitfalls for the general dental practitioner

Lichen planus is a chronic, mucocutaneous inflammatory condition which, due to its prevalence, will be familiar to the dental profession. However, diverse forms of presentation, important differential diagnosis, potential malignant change and monitoring requirements often result in challenges for those in primary care. This paper looks to examine these challenges and provide information to support those who are involved in recognition and management of patients with lichen planus.

Bridging the gaps: management of lichen planus subtypes in a joint dermatology-oral surgery clinic

Lichen planus (LP) presents with a range of clinical subtypes. It can affect the outer skin, involve the nails and present with alopecia and mucosal symptoms to varying degrees. LP of the outer skin mostly shows a self-limiting course; however, this is not the case for lichen planopilaris and the mucosa-affecting subtypes. The pathogenesis of LP is still incompletely understood. As a result, an effective, targeted therapy is currently lacking and different immunomodulatory approaches are being used in clinical practice. The management of patients with severe oral LP mucosae can be particularly challenging. Although the true risk remains controversial, oral LP is considered a risk factor for the development of squamous cell carcinoma and there is a need for regular screening. The quality of life in patients with LP is significantly impaired because of frequent clinical visits, pain, soreness, inability to eat certain foods, side effects to medication, frustrating therapy attempts and worry regarding cancer risk. We highlight here the advantages of an interdisciplinary dermatology and oral surgery clinic, which can address the domains of tooth status, nutrition, pain and malignant transformation and optimized patient management.

Development of the lichen planus quality of life questionnaire (LPQoL) informed by expert clinician input and patient feedback: a retrospective survey study

Lichen planus (LP) can affect multiple body sites including skin, mucosae, scalp and nails, causing considerable impact on patients' quality of life. Currently, there are no LP patient-reported outcome measures (PROMs) that address all body sites potentially affected by LP. We developed a LP Quality of Life Questionnaire (LPQoL), informed by an expert consortium and patient survey study, to address this gap. The study was approved by our institution's Institutional Review Board. First, a 22-item LPQoL was designed with input from LP experts at our institution. The tool was then optimized by garnering input from patients recently diagnosed with LP, who were asked to complete the LPQoL, as well as the Dermatology Life Quality Index (DLQI) and a feedback form about the LPQoL. Fifty-eight of 150 patients (39% response rate) returned the questionnaire. Mean DLQI score was 4.9 ± 5.6 SD (range 0-25) and mean LPQoL score was 13.6 ± 10.4 SD (range 0-54). LPQoL score was positively correlated with DLQI score (r = 0.79; p < 0.001). Forty-nine out of 56 (88%) and 6/56 (11%) rated the LPQoL as 'very easy' or 'fairly easy' to complete, respectively. Based on participants' feedback, we increased the recall period from one week to one month and added questions on esophageal involvement. With iterative input from LP experts and patients, we developed a LPQoL to address the gap in a multi-site PROM specific to LP. This is a pilot study and there is ongoing validation studies; therefore, this measure should not be used in clinical practice or research until validated.

Psychological Functioning of Women Diagnosed with Lichen Planus and Other Diseases of the Oral Cavity-Explorative Study

The role of psychosocial factors in the development of changes in lichen planus and other diseases of the oral cavity has been implicated, but is still understudied. Therefore, the aim of our study was to describe the specific profile of psychological functioning of patients with these diseases, including the role of temperamental traits, action-oriented personality components, and self-esteem. In total, 94 adult women participated in the study: (1) with lichen planus (LP; n = 46; M_age = 54.80, SD = 12.53), (2) with other oral conditions (n = 25; M_age = 34.76, SD = 16.03), (3) without chronic disease (n = 24; M_age = 40.96, SD = 13.33). The following questionnaires were used: ZKA-PQ/SF, Polish Adaptive and Maladaptive Perfectionism Questionnaire, ACS-90, PROCOS, and MSEI. Results indicated no significant differences in temperament dimensions between studied groups. However, women diagnosed with LP presented lower levels of maladaptive perfectionism and social support than healthy women. Furthermore, women with LP also obtained lower scores for social resourcefulness and higher scores for moral self-approval than healthy women. Summarizing, patients with LP often use compensatory mechanisms that negatively affect their social functioning; thus diagnostic/therapeutic programs directed towards those group should be holistic, including psychologists and psychiatrists who support patients' psychological well-being.

Oral health-related quality of life in erosive/ulcerative oral lichen planus patients

Background

Oral lichen planus (OLP) is a chronic oral mucosal disease. It can manifest as severe erosive/ulcerative oral lesions, causing pain and discomfort. Oral health-related quality of life (OHRQoL) may be deteriorated due to the patient's symptoms. The aim of this study was to evaluate OHRQoL and its relation to oral pain in erosive/ulcerative OLP patients.

Materials and Methods

In this cross-sectional study, patients with erosive/ulcerative OLP filled out Chronic oral mucosal disease questionnaire (COMDQ). Meanwhile, they recorded their oral pain through Visual analog scale (VAS). The Pearson's correlation coefficient was used to analyze the relationship between COMDQ score and VAS (IBM SPSS Statistics). P < 0.05 was considered statistically significant.

Results

Sixty patients participated in the present study; 51 (85%) were women and 9 (15%) were men. The mean age of participants was 50 ± 14.5 years. The mean score of COMDQ was 47.44 (±18.21). The mean VAS score was 4.5 (±2.4). COMDQ total and all domain scores were significantly correlated with VAS (P < 0.05), except for the "Patient support" domain (P = 0.63).

Conclusion

In patients with erosive/ulcerative OLP, there was a significant correlation between oral pain and COMDQ total score, as well as its physical, social, and emotional domains. It seems that COMDQ can be a complementary tool for assessing treatment outcomes in OLP patients.

Oral Health, Antimicrobials and Care for Patients With Chronic Oral Diseases – A Review of Knowledge and Treatment Strategies

Periodontal and chronic oral mucosal diseases are significant life impacting conditions which may co-exist and synergistically act to cause more severe and widespread oral pathology with enhanced challenges in effective management. Clinicians regularly observe these effects and struggle to effectively manage both problems in many patients. There is limited understanding of many basic and applied scientific elements underpinning potentially shared aetiopathological features and management. Recent developments in translational science provide an opportunity to greater improve knowledge and subsequently care for patients with these problems.

The Influence of Hepatitis C Virus Infection on ORAL Health-Related Quality of Life in Patients with Oral Lichen Planus

Background: oral lichen planus (OLP) is a mucocutaneous disease that affects about 4% of the global population. Hepatitis C virus (HCV) was linked to lichen planus. The current study aimed to assess the impact of OLP associated or not with HCV infection on the oral health-related quality of life (OHRQoL). Methods: The study included patients diagnosed with OLP who filled in the Romanian version of OHIP-14 questionnaire at their first appointment and 6 months later, after the OLP treatment. A control group of OLP-free subjects similar as age and sex was also included in the study. Results: 68 patients with OLP and 46 controls were included in the study. The OHIP scores are significantly higher on OLP group than controls (p-value < 0.0001) and significantly reduced at 6-month follow-up (p-values: < 0.0001 pre- vs. post-treatment in OLP group). Patients with and without HCV associated with OLP demonstrated a similar oral quality of life (p-values > 0.05). Conclusions: the OHRQoL for patients suffering from OLP is compromised but is improved after treatment. The HCV associated with OLP did not influence the overall OHRQoL, but the patients who associate HCV reported more frequently aching in the mouth and discomfort eating food at six-month follow-up.

A Comparison of Clinical Efficiency of Photodynamic Therapy and Topical Corticosteroid in Treatment of Oral Lichen Planus: A Split-Mouth Randomised Controlled Study

Background: The aim of the study was to compare the effectiveness of photodynamic therapy (PDT) to steroid therapy in the treatment of oral lichen planus (OLP). Due to the lack of commercially available drug carriers, innovative proprietary solutions were used for both the photosensitiser and the steroid carrier—in the first case to shorten and in the second to extend the contact of the active substance with the mucosa. Methods: A prospective, randomised, single-blind, 12-week full contralateral split-mouth clinical trial of 30 patients with bilateral oral lichen planus was conducted. The prepared matrices were incorporated with active substances methylene blue 5% and 0,05% triamcinolone. The size of lesions, Thongprasom, ABISIS, and VAS scale were evaluated. Results: Relatively high rates of complete remission of lichen were demonstrated: immediately after treatment, 33.3% with PDT and 22.2% with triamcinolone (TA), and after 3 months, 54.2% with PDT and 62.9% with TA. After 3 months of treatment, a reduction in the area of evaluated lesions of 52.7% for PDT and 41.7% for TA was achieved. Conclusion: In situations of topical or general contraindications to oral corticosteroids, resistance to them, or the need for repeated treatment in a short period of time, PDT appears to be a very promising treatment option.
