Double-blind clinical trial of 0.05% clobetasol propionate (corrected from proprionate) ointment in orabase and 0.05% fluocinonide ointment in orabase in the treatment of patients with oral vesiculoerosive diseases

Analysis of a Combination Therapy Protocol for the Treatment of Oral Mucous Membrane Pemphigoid: A Retrospective Case Series Study

Mucous membrane pemphigoid (MMP) is an autoimmune-based bullous disease affecting the mucous membranes, mainly oral and ocular. One of the most common clinical manifestations is desquamative gingivitis (DG), characterized by intense symptoms and functional limitations. The dentist is among the first specialists to observe DG and, therefore, must be able to diagnose it. In this regard, the purpose of the present study was to evaluate the efficacy and safety of a clinical protocol for the topical management of patients with DG and MMP buccal lesions. Thirteen patients with clinical and histologic diagnoses of MMP-localized DG in the oral cavity were retrospectively enrolled. Each patient received topical treatment with clobetasol propionate oral gel 0.05%; nicotinamide; oral probiotic (contains Bifidobacterium lactis HN019, Kluyveromyces marxianus fragilis B0399, colostrum, and biotin); and doxycycline. Before and after 3 months of therapy, clinic records were collected for each patient. Seven patients (53.8%) had a complete response to treatment; four patients (30.8%) had a partial response to treatment; and, finally, two patients (15.4%) had no benefit from therapy. Dental management of patients presenting solely with oral manifestations of MMP may involve the use of topical corticosteroids, doxycycline, vitamin supplements, and probiotics and associating professional oral hygiene procedures.

Factors Associated with Candidiasis in Pemphigus Vulgaris Patients: Results from a Retrospective Study in Two Second-Care Level Hospitals in Mexico

BACKGROUND

Infections are a major cause of morbidity and mortality in patients with pemphigus vulgaris (PV). One of the most common infections in these patients is candidiasis. This is probably due to the use of systemic immunosuppressants, including oral and intravenous corticosteroids, mainly in megadoses (pulse therapy), although it is unknown if there are other associated factors, in addition to immunosuppressive treatment. We determine the factors associated with candidiasis in PV patients in two second-care level hospitals in Mexico.

METHODS

We reviewed 100 cases with PV. Cases were randomly selected from the databases of two second-care level hospitals between January 2010 and December 2019 (10 years). The primary endpoint was the incidence of candidiasis in patients with PV.

RESULTS

One hundred patients with PV were enrolled in this retrospective study. Candidiasis was observed in 79 patients (79%). A maximum corticosteroid dose of 55 mg/day during the last year (p = 0.001) and a higher neutrophil/lymphocyte ratio were associated with candidiasis in patients with PV (p = 0.001).

CONCLUSION

Risk factors favoring candidiasis in patients with PV are not only related to the use of corticosteroids, but also to demographic factors, the activity of the disease, and the systemic inflammation associated with autoimmunity.

Evaluating the Efficacy of the Er,Cr:YSGG Fractional Laser Before Treatment With Triamcinolone NN Ointment in Oral Lichen Planus Lesions

Introduction: It has been demonstrated that laser technology can enhance topical drug absorption. This study aimed to determine the effects of Er,Cr:YSGG laser radiation before the application of topical corticosteroids in the healing of oral lichen planus. Methods: In this double-blind split-mouth clinical trial, 32 lesions were chosen from eight patients affected by oral lichen planus (OLP). The oral lesions were randomly categorized into two groups. The first group had topical treatment with triamcinolone NN ointment and the second group had laser radiation (Er,Cr:YSGG) for eight weeks before starting the ointment. For each lesion, the irritating level based on the VAS score, the lesion level based on the Thongprasom scale score, and the healing time were measured, and the collected data were analyzed by the Friedman test and the Wilcoxon’s statistical test. Results: The mean healing time based on the verbal analog scale (VAS) score was not significantly different between the two treatment groups (P>0.05). The mean healing time based on Thongprasom scale scores did not show any significant difference between the two treatment groups (P>0.05). Conclusion: The application of the Er,Cr:YSGG laser before treatment with triamcinolone NN ointment did not show any advantage for the average healing time compared to a medicine regimen with only triamcinolone NN ointment.

Autoimmune Pemphigus: Latest Advances and Emerging Therapies

Pemphigus represents a group of rare and severe autoimmune intra-epidermal blistering diseases affecting the skin and mucous membranes. These painful and debilitating diseases are driven by the production of autoantibodies that are mainly directed against the desmosomal adhesion proteins, desmoglein 3 (Dsg3) and desmoglein 1 (Dsg1). The search to define underlying triggers for anti-Dsg-antibody production has revealed genetic, environmental, and possible vaccine-driven factors, but our knowledge of the processes underlying disease initiation and pathology remains incomplete. Recent studies point to an important role of T cells in supporting auto-antibody production; yet the involvement of the myeloid compartment remains unexplored. Clinical management of pemphigus is beginning to move away from broad-spectrum immunosuppression and towards B-cell-targeted therapies, which reduce many patients’ symptoms but can have significant side effects. Here, we review the latest developments in our understanding of the predisposing factors/conditions of pemphigus, the underlying pathogenic mechanisms, and new and emerging therapies to treat these devastating diseases.

Childhood oral lichen planus: a case series with review of literature

BACKGROUND

Oral Lichen Planus (OLP) is a chronic autoimmune mucocutaneous condition, the exact etiology of which is still unknown. It is known to occur chiefly in adults and has a reported prevalence of 0.5-2% in general population and < 2-3% of total in pediatric population. OLP is considered as Oral Potentially Malignant Disorder with a malignant transformation rate of 1-2% in adults. Its occurrence in children is a rare finding with few cases reported in the literature. As a result, it gets misdiagnosed by the general practitioner and hence, there is a need to consider OLP in differential diagnosis of white lesions of oral cavity even in children. Therefore, in this paper, we present six cases of childhood OLP along with their management and follow-up.

CASE SERIES

We present here six patients aged between 11 and 13 years who presented either as incidental finding or as symptomatic lesions and were diagnosed with OLP. Symptomatic patients were treated with topical steroid ointment and both the symptomatic and asymptomatic patients were followed-up. We have also presented literature review of childhood OLP reported in PubMed, Medline and google scholar from 1980 till December 2020.

CONCLUSION

OLP is unusual in children and is often left untreated due to low awareness among the patients. Can be often misdiagnosed and should be considered in differential diagnosis of any white lesion of oral cavity. Any such lesions must be correctly diagnosed in time to institute appropriate management and follow-up.

Corticosteroid delivery using oral mucosa equivalents for the treatment of inflammatory mucosal diseases

Oral lichen planus (OLP) is an immune‐mediated disease of the oral mucosa with idiopathic aetiology. It is frequently treated with topical corticosteroids (applied as gels, mouthwashes, or sprays); however, the mucosal exposure times of topical corticosteroids are short because of removal by the constant flow of saliva and mechanical forces. In this study we used cell monolayers, as well as oral mucosal equivalents (OMEs) containing activated T‐cells, to examine corticosteroid potency and delivery of clobetasol‐17‐propionate from a novel electrospun mucoadhesive patch. The OMEs displayed tight junctions, desmosomes, hemidesmosomes, and an efficient permeability barrier. Following application of corticosteroids to cells cultured as monolayers, the degree of cytotoxicity measured correlated to the level of potency recognized for each corticosteroid; by contrast, OMEs were largely unaffected by corticosteroid treatment. Permeation of clobetasol‐17‐propionate into and through the OMEs was time‐ and dose‐dependent, regardless of whether this corticosteroid was delivered in liquid form or from a mucoadhesive patch, and both liquid‐ and patch‐delivered clobetasol‐17‐propionate significantly reduced the secretion of interleukin‐2 by activated T‐cells. This study confirms that OMEs are more suitable models than cell monolayers for evaluating toxicity and drug delivery. After topical exposure, clobetasol‐17‐propionate accumulated in OMEs at a higher level than betamethasone‐17‐valerate and hydrocortisone‐17‐valerate, and exerted its immunosuppressive actions following application via the patch delivery system, highlighting the efficacy of this mode of drug delivery to treat OLP.

Custom-made trays for targeted treatment of oral vesiculobullous diseases: A proposed protocol

Topical and intralesional corticosteroids (CS) are effective treatments for oral manifestations of autoimmune vesiculobullous diseases (VBD); however, may cause unnecessary absorption in the adjacent healthy mucosal surfaces, local infections, atrophy, and injection pain. To propose a protocol using a unique modality for targeted administration of CS for the treatment of local manifestations of oral VBD. The medical records of nine patients with systemic CS-resistant VBD oral lesions, were reviewed following 3 weeks of treatment and 3 months of tapering using a custom-made tray designed for precise application of topical CS targeted to the involved mucosa. Following treatment, lesions have healed in 8/9 patients. Involvement of surrounding mucosa was minimal, and no systemic adverse effects were recorded. The proposed protocol using custom-made trays for targeted CS treatment could be an effective alternative treatment for oral VBD.

Lichen planus: Oral manifestations, differential diagnosis and treatment

Introduction: Some of the typical skin diseases, such as Pemphigus vulgaris, Pemphigoid mucosae oris, Erythema exudativum multiforme, Sclerodremia, Dermatitis herpetiformis-Duhring and Lichen planus, can cause swelling and irritation in mucous membranes of the oral cavity. Aim: The aim of the study was to precise diagnosis and treatment of oral Lichen planus manifestations. Methods: Analyzing the literature data and the experience of clinicians, the most common oral lichen planus manifestations were investigated. Results: This disease most commonly occurs in middle-aged patients (30-60 years) and is more common in women than in men. Oral Lichen planus is rarely seen in children. The disease presents in 0.5% to 2% of the population. Clinical history established the relation between oral Lichen planus and oral carcinoma, and therefore this disease should be considered a precancerous lesion. Conclusion: Dermatoses in the mouth are localized most often in the oral mucosa, both at the height of the occlusal line and in the mucous membrane of the retromolar area, but they can also occur in the mucous membranes of the tongue, the floor of the mouth and lips.

Oral lichen planus: A disease or a spectrum of tissue reactions? Types, causes, diagnostic algorhythms, prognosis, management strategies

Oral lichen planus and lichenoid lesions comprise a group of disorders of the oral mucosa that likely represent a common reaction pattern to 1 or more unknown antigens. The coexistence of hyperkeratotic striation/reticulation, varying degrees of mucosal inflammation from mild erythema to severe widespread ulceration, and a band-like infiltrate of mononuclear inflammatory cells including activated T lymphocytes, macrophages, and dendritic cells, are considered suggestive of oral lichen planus and lichenoid lesions. Several classification systems of oral lichen planus and lichenoid lesions have been attempted, although none seem to be comprehensive. In this paper, we present a classification of oral lichen planus and lichenoid lesions that includes oral lichen planus, oral lichenoid contact lesions, oral lichenoid drug reactions, oral lichenoid lesions of graft vs. host disease, discoid lupus erythematosus, and systemic lupus erythematosus, lichen planus-like variant of paraneoplastic pemphigus/paraneoplastic autoimmune multiorgan syndrome, chronic ulcerative stomatitis, lichen planus pemphigoides, solitary fixed drug eruptions, and lichen sclerosus. We present the clinical and diagnostic aspects of oral lichen planus and lichenoid lesions, and discuss related treatment options.

The effect of triamcinolone in liposomes on oral wound healing in rats

The purpose of this study was to determine whether oral mucosa wounds in rats can be successfully treated with triamcinolone acetonide (TA), incorporated into liposomes. A round wound was inflicted on the oral mucosa of female Wistar rats divided into four groups of 12 animals. This wound was treated topically from day 1 with liposomes without the inclusion of TA and liposomes containing 0.01% or 0.05% TA. The wounds of the animals in the control group were not treated. Polymethyl metacrylate was used as an ointment for mixing in liposomes. The size of the wound was measured until day 6. The area of inflammatory infiltrate under the wound was evaluated by histopathology, the expression of iNOS (inducible nitric oxide synthase) enzyme under the wound was evaluated by immunohistochemistry until day 6. On the sixth day of experiment, the size of the wound and the area of the inflammatory infiltrate was the smallest in the group receiving empty liposomes (EL). Expression of iNOS was the most reduced in the group receiving EL. We conclude that oral mucosa wounds can be successfully treated with liposomes, although the incorporated drug triamcinolone would not be the appropriate drug for treating wounds of traumatic origin.

Electrophoretic bottom up design of chitosan patches for topical drug delivery

Clobetasol propionate (CP) is a high-potency corticosteroid, representing the standard of care for the symptomatic treatment of different skin disorders as well as oral mucosal diseases. Several topical delivery systems are available for treating oral lesions, but the ideal one is still lacking. In this work, we propose a novel class of chitosan (CS) patches, loaded with CP, for the topical treatment of inflammatory chronic oral diseases. Chitosan patches have been fabricated via electrophoretic deposition (EPD), by using a one-pot approach in order to load controlled quantity of CP. Optimized structures showed a water uptake in the range of 200-360% and mechanical properties that allow the design of flexible patches in wet state (E = 0.6 MPa and σ_br = 0.55 MPa). Ultraviolet-visible (UV-Vis) spectroscopy was used for the evaluation of both loading and release profile of CP in CS patches. The CP loading has been tuned by adjusting CP concentration in deposition bath-in the range 0.002-0.12 mg cm^-2-while releasing curves show an in vitro CP burst of about 80% in the first two hours. Overall, the obtained properties paved the way for the application of this new class of patches for the local oral release of CP.

How I treat refractory chronic graft-versus-host disease

Approximately 35% to 50% of patients otherwise cured of hematologic malignancies after allogeneic hematopoietic stem cell transplantation will develop the pleomorphic autoimmune-like syndrome known as chronic graft-versus-host disease (cGVHD). Since in 2005, National Institutes of Health (NIH) consensus panels have proposed definitions and classifications of disease to standardize treatment trials. Recently, the first agent was approved by the US Food and Drug Administration for steroid-refractory cGVHD. Despite these advances, most individuals do not achieve durable resolution of disease activity with initial treatment. Moreover, standardized recommendations on how to best implement existing and novel immunomodulatory agents and taper salvage agents are often lacking. Given the potential life-threatening nature of cGVHD, we employ in our practice patient assessment templates at each clinic visit to elucidate known prognostic indicators and red flags. We find NIH scoring templates practical for ongoing assessments of these complex patient cases and determination of when changes in immunosuppressive therapy are warranted. Patients not eligible or suitable for clinical trials have systemic and organ-directed adjunctive treatments crafted in a multidisciplinary clinic. Herein, we review these treatment options and offer a management and monitoring scaffold for representative patients with cGVHD not responding to initial therapy.

Identification of factors associated with treatment refractoriness of oral lesions in pemphigus vulgaris

BACKGROUND

The oral mucosal lesions of patients with pemphigus vulgaris are known to show more treatment refractoriness than skin lesions.

OBJECTIVES

To identify which clinical and laboratory parameters may indicate treatment refractoriness of oral lesions in pemphigus vulgaris.

METHODS

This was a prospective study of 50 adults with pemphigus vulgaris and oral lesions; patients were given treatment appropriate for overall disease severity. Treatment refractoriness was defined arbitrarily as less than 75% reduction in oral objective Autoimmune Bullous Skin Disorder Intensity Score (ABSIS) after treatment for 6 months.

RESULTS

Of 46 patients who completed the study, 17 (37%) were treatment refractory whereas 29 (63%) were treatment responsive. At baseline, the treatment refractory group had a significantly longer mean duration of disease (P = 0·02) and mean duration of oral lesions (P = 0·01), a higher percentage of lesions in the retromolar trigone (P = 0·05) and on the occlusion line along the buccal mucosa (P = 0·04), a higher percentage of deep/crateriform ulcers (P < 0·001) and erosions with a lichenoid hue (P < 0·001). Herpes simplex virus (HSV) DNA positivity, assessed by polymerase chain reaction in oral tissue scrapings (P = 0·02), was also significantly higher in the treatment refractory group. No other factors we tested for were statistically significant.

CONCLUSIONS

Treatment refractoriness of oral lesions was significantly associated with duration of disease/oral lesions; specific morphology and location of oral lesions; and the presence of HSV DNA in the oral cavity. These factors may forewarn the treating physician about a refractory course of oral lesions that may help with counselling patients.

Vesiculo-erosive Oral Mucosal Disease—Management with Topical Corticosteroids: (1) Fundamental Principles and Specific Agents Available

Vesiculo-erosive diseases of the oral mucosa pose a major challenge in oral medicine, because they are chronic, painful, and interfere with the daily activities and quality of life of the patients, including disturbing eating, drinking, talking, and personal relationships. Many are autoimmune diseases, and corticosteroid therapy is currently central to their treatment. These diseases present with inflammation and alterations to epithelial integrity, through cell and/or humoral immunity-mediated attack on epithelial-connective tissue targets. Until recently, despite their serious adverse effects, it was necessary to prescribe systemic corticosteroids to control severe erosive oral diseases. Now, however, many of these diseases can be controlled by high-potency topical corticosteroids, which have proved to be highly efficacious and to cause fewer adverse effects compared with systemic corticosteroids. Nevertheless, although topical corticosteroids are still the most widely used drugs in the practice of oral medicine, the scientific body of evidence for their use in the oral cavity is virtually non-existent, and therefore many of the protocols followed are, of necessity, drawn from experience of their use in a dermatological setting. This review aims to set out the key aspects of the use of topical corticosteroids in oral medicine. The issues covered include the indications and basic rules for their use, the types of corticosteroids, the drug selection, and the specific formulations.

Vesiculo-erosive Oral Mucosal Disease—Management with Topical Corticosteroids: (2) Protocols, Monitoring of Effects and Adverse Reactions, and the Future

Although topical corticosteroids (TCs) are the most widely used drugs in oral medicine, and specifically in the treatment of vesiculo-erosive oral mucosal disease, there are few evidence-based data for the correct use of these drugs. In this review, we outline the most widely used protocols, the most common reasons for treatment failure, and the adverse effects documented in the literature.

Clinical features of gingival lesions in patients with dystrophic epidermolysis bullosa: a cross-sectional study

BACKGROUND

Gingival lesions in patients with dystrophic epidermolysis bullosa (DEB) are a common manifestation. However, their clinical features, frequency and severity are currently unknown.

METHODS

Forty-five DEB patients were assessed by an oral medicine specialist, who analysed the presence/absence of four clinical signs (erythema, erosion/ulcer, atrophy, blister) on free and attached gingiva, using the Epidermolysis Bullosa Oropharyngeal Severity score.

RESULTS

Twenty-eight (62.2%) out of 45 DEB patients showed different types of gingival lesions, whose presence/absence and total frequency/distribution were not significantly different between males and females (p=0.087 and p=0.091, respectively). Erythema was the most prevalent lesion (66.2%) and the recessive DEB severe generalized (RDEB-sev gen) reached the highest median disease activity score. A significant correlation was observed between the DEB subtypes and the disease activity median score (p<0.001), but not between age and total disease activity score in each group of DEB (p>0.05). Lastly, logistic regression showed that only gender (p=0.031) and RDEB-sev gen (p=0.001) were risks factors for the presence of gingival lesions.

CONCLUSIONS

Gingival lesions in DEB patients are a relatively common entity and may have multiple clinical aspects, emphasizing the need for thorough attention and awareness among dentists.

Assessment and management of gastrointestinal toxicities and lab abnormalities related to targeted therapy

OBJECTIVES

To identify the most common gastrointestinal toxicities and laboratory abnormalities associated with targeted therapies, as well as the assessment and management necessary to minimize adverse events related to these side effects.

DATA SOURCES

Peer-reviewed articles and national guidelines for oncology practice.

CONCLUSION

Common toxicities of diarrhea, mucositis, and laboratory abnormalities are often associated with the use of targeted agents and require skilled assessment and early management interventions to prevent severe complications or treatment interruption.

IMPLICATIONS FOR NURSING PRACTICE

Emerging trends focused on targeted therapy increase the importance of the oncology nurse's role in assessment, education, and evidenced-based recommendations to meet patient needs.

Intralesional injection versus mouth rinse of triamcinolone acetonide in oral lichen planus: a randomized controlled study

OBJECTIVE

To compare the efficacy, relapse, and adverse effects between intralesional injection and mouth rinse of triamcinolone acetonide (TA) in patients with oral lichen planus (OLP).

STUDY DESIGN

A randomized controlled study.

SETTING

College medical center.

SUBJECTS AND METHODS

Forty consecutive patients, who had been diagnosed with OLP, were recruited. Participants were randomly divided into 2 groups using intralesional injection or mouth rinse of TA. The severity of pain and burning sensation on a 10-cm visual analog scale (VAS) and the Oral Health Impact Profile-14 (OHIP-14) were assessed at weeks 0, 1, 2, 3, 4, and 6. The signs of OLP were quantified using a special scoring system for OLP. The rate of relapse and the adverse effects were compared between both groups.

RESULTS

The VAS scores for pain and burning mouth sensation and objective scoring for OLP were significantly improved at 1, 2, 3, 4, and 6 weeks in both groups. The changes in the VAS for burning mouth sensation, OHIP-14, and objective scoring for OLP were similar between both groups. The change in the VAS for pain from baseline to week 1 in the intralesional injection group was significantly higher than in the mouth rinse group. The rate of adverse effects was significantly higher in the mouth rinse group than in the intralesional injection group (44.4% vs 5.0%).

CONCLUSION

The efficacies of both treatments were similar. The rate of adverse effects was significantly lower for intralesional injection of TA than mouth rinse of TA.

Topical tacrolimus with custom trays in the treatment of severe oral chronic graft-versus-host disease refractory to a potent topical steroid therapy: a case report

BACKGROUND

The authors present a case demonstrating the success of topical tacrolimus (TAC) therapy with custom trays in the treatment of oral chronic graft-versus-host disease (cGVHD). The 41-year-old male patient initially responded to topical steroid therapy (clobetasol propionate 0.05% ointment) applied both topically and with flexible carrier trays, but later became refractory to this potent topical agent. Topical TAC therapy with flexible carrier trays and systemic prednisone therapy was initiated.

RESULTS

The patient responded favorably with the change to topical TAC therapy with custom trays (and oral prednisone). His oral cGVHD lesions resolved within a period of 4 weeks. The improvement has remained stable at 14 months of follow-up.

CLINICAL IMPLICATIONS

This is the first case reported with regard to the successful resolution of steroid recalcitrant cGVHD successfully treated with topical TAC with custom trays.

Interventions for erosive lichen planus affecting mucosal sites

BACKGROUND

Erosive lichen planus (ELP) affecting mucosal surfaces is a chronic autoimmune disease of unknown aetiology. It is often more painful and debilitating than the non-erosive types of lichen planus. Treatment is difficult and aimed at palliation rather than cure. Several topical and systemic agents have been used with varying results.

OBJECTIVES

To assess the effects of interventions in the treatment of erosive lichen planus affecting the oral, anogenital, and oesophageal regions.

SEARCH METHODS

We searched the following databases up to September 2009: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE (from 2005), EMBASE (from 2007), and LILACS (from 1982). We also searched reference lists of articles and online trials registries for ongoing trials.

SELECTION CRITERIA

We considered all randomised controlled trials (RCTs) that evaluated the effectiveness of any topical or systemic interventions for ELP affecting either the mouth, genital region, or both areas, in participants of any age, gender, or race.

DATA COLLECTION AND ANALYSIS

The primary outcome measures were as follows:(a) Pain reduction using a visual analogue scale rated by participants; (b) Physician Global Assessment; and (c) Participant global self-assessment.Changes in scores at the end of therapy compared with baseline were analysed.

MAIN RESULTS

A total of 15 RCTs were identified, giving a total of 473 participants with ELP. All studies involved oral ELP only. Six of the 15 studies included participants with non-erosive lichen planus. In these studies, only the erosive subgroup was included for intended subgroup analysis. We were unable to pool data from any of the nine studies with only ELP participants or any of the six studies with the ELP subgroup, due to small numbers and the heterogeneity of the interventions, design methods, and outcome variables between studies. One small study involving 50 participants found that 0.025% clobetasol propionate administered as liquid microspheres significantly reduced pain compared to ointment (Mean difference (MD) -18.30, 95% confidence interval (CI) -28.57 to -8.03), but outcome data was only available in 45 participants. However, in another study, a significant difference in pain was seen in the small subgroup of 11 ELP participants, favouring ciclosporin solution over 0.1% triamcinolone acetonide in orabase (MD -1.40, 95% CI -1.86 to -0.94). Aloe vera gel was 6 times more likely to result in at least a 50% improvement in pain symptoms compared to placebo in a study involving 45 ELP participants (Risk ratio (RR) 6.16, 95% CI 2.35 to 16.13). In a study involving 20 ELP participants, 1% pimecrolimus cream was 7 times more likely to result in a strong improvement as rated by the Physician Global Assessment when compared to vehicle cream (RR 7.00, 95% CI 1.04 to 46.95).There is no overwhelming evidence for the efficacy of a single treatment, including topical steroids, which are the widely accepted first-line therapy for ELP. Several side-effects were reported, but none were serious. With topical corticosteroids, the main side-effects were oral candidiasis and dyspepsia.

AUTHORS' CONCLUSIONS

This review suggests that there is only weak evidence for the effectiveness of any of the treatments for oral ELP, whilst no evidence was found for genital ELP. More RCTs on a larger scale are needed in the oral and genital ELP populations. We suggest that future studies should have standardised outcome variables that are clinically important to affected individuals. We recommend the measurement of a clinical severity score and a participant-rated symptom score using agreed and validated severity scoring tools. We also recommend the development of a validated combined severity scoring tool for both oral and genital populations.

Therapeutic approaches to patients with mucous membrane pemphigoid

The therapeutic approach to mucous membrane pemphigoid is site specific, with the goal of preserving function for patients with chronic and treatment-resistant disease. The involvement of certain mucosal sites (ie, ocular, laryngeal, esophageal, nasopharyngeal, and anogenital) is high risk and warrants more aggressive intervention. Control of the disease must be balanced with minimizing the sequelae of long-term exposure to systemic glucocorticosteroids and/or other immunosuppressives. Timely interventions and multidisciplinary management are essential in preventing disability.

Adjuvant triamcinolone acetonide injections in oro-pharyngeal pemphigus vulgaris

BACKGROUND

High-potency topical and perilesional/intralesional corticosteroids are becoming increasingly useful as adjuvant to treat autoimmune blistering diseases.

OBJECTIVE

We sought to evaluate the role of perilesional/intralesional triamcinolone acetonide (PITA) injections in reducing the time for first complete clinical remission and the total amount of systemic corticosteroids in oro-pharyngeal pemphigus vulgaris (OPV) patients, and also the compliance of PITA injections, in terms of satisfaction, pain and discomfort.

METHODS

Thirty-five OPV patients were treated with conventional immunosuppressive therapy (CIST) and received high potency topical corticosteroids (clobetasol and/or methylprednisolone) and/or PITA injections. Patients were grouped as follows: (i) a group of 16 patients was treated with PITA injections and (ii) a group of 19 patients without PITA injections.

RESULTS

Sixteen patients treated with PITA injections and 19 without PITA injections reached complete clinical remission within 126.6 days (SD: 41; 95% CI: 104.7-148.8) and 153.2 days (SD: 97.4; 95% CI: 106.2-200.1) (P = 0.4) respectively. The total amount of corticosteroids in patients treated with PITA and without PITA was 4894 mg (SD: 2832; 95% CI: 3385-6403) and 5312 mg (SD: 4009; 95% CI: 3380-7245) (P = 0.4) respectively. Patients treated with PITA reported a satisfaction score significantly higher than pain (P = 0.0007) and discomfort score (P = 0.0006).

CONCLUSION

Perilesional/intralesional triamcinolone acetonide injections seems to represent a helpful clinical tool to successfully join CIST, in terms of shortening the time of complete clinical remission, reducing the total amount of corticosteroids and obtaining an acceptable compliance.

Therapeutic Management of Oral Lichen Planus: A Review for the Clinicians

Lichen planus is a chronic, noninfectious, inflammatory disease of skin and mucous membrane. Intraorally the buccal mucosa, tongue and gingiva are the sites commonly involved. It affects women more often than men in a ratio 3:2. It has well-recognized clinical signs and symptoms, the symptoms may range from none, through mild discomfort to severe burning sensation. In comparison with cutaneous form, the oral lesions are more resistant to therapy and are less likely to undergo spontaneous remission.

Treatment is administered mainly to resolve symptoms and discomfort. Choice of treatment may vary from patient to patient depending on the severity of the lesion and systemic condition of the patient. A variety of agents have been employed to treat oral lichen planus, but corticosteroid remains the mainstay of treatment. However, in the recent past, newer drugs like Tacrolimus have shown promising results. In view of fact that there is a risk of malignant transformation of atrophic and erosive forms of oral lichen planus, the patients need to be actively treated and kept on long-term follow-up. This article highlights various agents used in treatment of oral lichen planus, their mechanism of action, dosage and untoward effects.

Pimecrolimus 1% cream for oral erosive lichen planus: a 6-week randomized, double-blind, vehicle-controlled study with a 6-week open-label extension to assess efficacy and safety

OBJECTIVE

To assess the efficacy and safety of topical pimecrolimus 1% cream in the treatment of oral erosive lichen planus.

DESIGN

A 6-week randomized, double-blind, vehicle-controlled phase followed by a 6-week open-label phase.

SETTING

Outpatients of the Department of Dermatology, University of Utah.

PATIENTS

Twenty-one patients with oral erosive lichen planus were randomized and treated with either pimecrolimus 1% cream or vehicle cream.

INTERVENTION

Pimecrolimus 1% cream, or its vehicle, were applied twice daily for 6 weeks to each side of the mouth with a 2×2 inch gauze pad folded in half and placed directly on the erosive lesion.

MAIN OUTCOME MEASURES

Efficacy was based on clinical evaluation of Investigator's Global Assessment (IGA) of the overall severity of the disease, erythema, measurement of the size of any target erosion in millimetres, and assessment of spontaneous pain. Blood levels of pimecrolimus were monitored in all subjects on day 0 and repeated on day 7.

RESULTS

Pimecrolimus 1% cream was superior to vehicle cream in reducing mean IGA, pain, and erosion size. For the vehicle group that entered the open-label phase, pimecrolimus 1% cream improved the mean IGA, pain, erosion size, and erythema. Pimecrolimus levels were detected in nine out of 10 of the pimecrolimus-treated subjects. These levels were consistently low. The pimecrolimus cream was well-tolerated. No clinically relevant, drug-related adverse events were reported.

CONCLUSION

Pimecrolimus 1% cream was superior to vehicle in reducing pain, erythema, decreasing erosion size, and improving overall severity of disease when compared with vehicle treatment.

Pathophysiology, etiologic factors, and clinical management of oral lichen planus, part I: facts and controversies

Lichen planus (LP) is an inflammatory disease of the stratified squamous epithelia of unknown etiology. LP affects most frequently the oral mucosa, but it may also involve other mucosa and the skin. Oral LP (OLP) most frequently affects woman aged between 30 and 60 years. Histopathologic examination typically shows orthokeratotic hyperkeratosis, basal cell degeneration, and a dense well-defined infiltrate of lymphocytes in the superficial dermis. OLP lesions may result from the induction of keratinocytes apoptosis by cytotoxic CD8+ T cells stimulated by a yet unidentified self-antigen on a genetically predisposed patient. The association of OLP with hepatitis C virus (HCV) has been more consistently demonstrated in the Mediterranean area. Although HCV RNA and HCV-specific CD4+ and CD8+ T cells have been retrieved in the mucosal lesions of patients with chronic HCV infection and OLP, the eventual pathophysiology of HCV in OLP lesions remains unclear. Available treatments of OLP are not curative, and many have potentially prominent side effects. The objectives of OLP management should be to prevent and screen for malignant transformation and alleviate symptoms on the long-term. Avoidance of potential precipitating drugs, tobacco, alcohol, and local trauma, as well as strict oral hygiene, is essential. The first-line pharmacologic treatment relies on topical steroids. Systemic steroids should be limited to the short-term cure of severe refractory OLP. Life-long clinical follow-up, at least annually, is fundamental.

Oral lichen planus: clinical features, etiology, treatment and management; a review of literature

Lichen planus is a chronic inflammatory mucocutaneous disease. Mucosal lesions are classified into six clinical forms and there is malignant potential for two forms of OLP; therefore, follow-up should be considered. There are many un-established etiological factors for OLP and some different treatment modalities are based on etiology. The aims of current OLP therapy are to eliminate mucosal erythema and ulceration, alleviate symptoms and reduce the risk of oral cancer. We have used review papers, case reports, cohort studies, and case-and-control studies published from 1985 to 2010 to prepare this review of literature.

Steriods in the treatment of lichen planus: a review

Steroids have been found to be effective in treating symptomatic oral lichen planus (OLP) by reducing pain and inflammation. In fact, systemic corticosteroids should be reserved for acute exacerbation, and multiple or widespread lesions. They may be indicated in patients whose condition is unresponsive to topical steroids. However, various potent topical steroids have been reported to be effective in the treatment of symptomatic OLP. They can be used as the first line drugs in the treatment of OLP with no serious side-effects. During the therapy, candidiasis was commonly found and in addition, bad taste, nausea, dry mouth, sore throat and swollen mouth may occur as minor side-effects from some topical steroids. Because OLP is a chronic disorder that requires long-term treatment, topical steroids are recommended for the treatment OLP because of minimal side-effects and the cost benefit. This manuscript reviews the use of steroids, especially its topical application, in the treatment of OLP.

Interventions for pemphigus vulgaris and pemphigus foliaceus

BACKGROUND

A range of interventions have been described for treatment of pemphigus, however the optimal therapeutic strategy has not been established.

OBJECTIVES

To assess the efficacy and safety of all interventions used in the management of pemphigus vulgaris and pemphigus foliaceus.

SEARCH STRATEGY

We searched the Cochrane Skin Group Specialised Register (October 2008), The Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 4, 2008), MEDLINE (2003 to October 2008), EMBASE (2005 to October 2008), LILACS (1981 to October 2008), Ongoing Trials Registers, reference lists of articles, conference proceedings from international pemphigus meetings and contacted experts in the field.

SELECTION CRITERIA

Randomised controlled trials of any intervention in pemphigus vulgaris or pemphigus foliaceus.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed quality and extracted data from studies. All investigators were contacted for further information. Adverse events were identified from included studies.

MAIN RESULTS

Eleven studies with a total of 404 participants (337 pemphigus vulgaris, 27 pemphigus foliaceus and 40 not specified ) were identified. The quality of included studies was not high, the majority of studies did not report allocation concealment, and power was limited by very small sample sizes. Interventions assessed included prednisolone dose regimen, pulsed dexamethasone, azathioprine, cyclophosphamide, cyclosporine, dapsone, mycophenolate, plasma exchange, topical epidermal growth factor and traditional Chinese medicine. Ten studies included participants with newly diagnosed or newly active recurrent disease, and one trial included participants in maintenance phase.There was sufficient data for 4 meta-analyses, each pooling results of two studies only. For the majority of interventions, results were inconclusive. We found some interventions to be superior for certain outcomes, although we were unable to conclude which treatments are superior overall. Mycophenolate was more effective in achieving disease control than azathioprine (1 study; n=40; RR 0.72; 95% CI 0.52 to 0.99, NNT 3.7). There was evidence of a steroid-sparing benefit of azathioprine (1 study; n=57; MWD -3919 mg prednisolone; 95% CI -6712 to -1126) and cyclophosphamide (1 study; n=54; MWD -3355 mg prednisolone; 95% CI -6144 to -566) compared to glucocorticoids alone. Topical epidermal growth factor decreased time to control (1 study; n=20; HR 2.35; 95% CI 1.62 to 3.41).

AUTHORS' CONCLUSIONS

There is inadequate information available at present to ascertain the optimal therapy for pemphigus vulgaris or pemphigus foliaceus. Further research is required, especially to assess the optimal glucocorticoid dose, the role of adjuvant immunosuppressive medications, and long-term adverse events to improve harm:benefit analyses.

Pemphigus pain: a review on management

Pemphigus vulgaris is an autoimmune disease that commonly presents with painful persistent erosions and ulcers.

OBJECTIVE

The current literature has focused on managing and maintaining remittance of this life-threatening disease. However, remission is not instantaneous and chronic pain is common. In this manuscript, we review the current peer reviewed works that elaborate specifically on pain management in pemphigus patients.

METHODS

A medline search was preformed and included any case report, review, clinical trial, or other publication that covered the subject matter.

RESULTS

From the review of literature, it is clear that pain is an important and underemphasized part of the literature on pemphigus. The majority of pain management in these patients is based on clinical experience rather than randomized blinded clinical studies.

DISCUSSION

Large scale blinded randomized studies are lacking in this field, and would be of great benefit to academia and the patient population. Current large-scale studies of pemphigus would also be strongly enhanced by inclusion and reporting pain scale assessments.

Double-blind, crossover, placebo-controlled clinical trial with clobetasol propionate in desquamative gingivitis

The aim of this study was to evaluate the efficacy of a 0.05% clobetasol propionate ointment administered in trays to 22 patients with desquamative gingivitis in a double-blind, crossover, placebo-controlled trial. Patients received container number 1 and were instructed to apply the ointment 3 times a day for 2 weeks, and to reduce the application to once a day in the third week. Next, the patients were then instructed to discontinue the treatment for 2 weeks, and were then given container 2, used in the same way and for the same length of time as container 1. Regarding signs, 17 patients presented some improvement, while 5 experienced worsening with clobetasol propionate. With the placebo, 14 patients presented some improvement, and 8 patients presented worsening. For symptoms, there was complete improvement in 2 patients, partial improvement in 12, no response in 7, and worsening in 1 with clobetasol propionate. With the placebo, there was partial improvement in 8 patients, no response in 12 and worsening in 2. No statistically significant difference was found between clobetasol and placebo (p>0.05). Within the period designed to treat the gingival lesions of the patients, clobetasol propionate did not significantly outperform the placebo.

Topical clobetasol in the treatment of atrophic-erosive oral lichen planus: a randomized controlled trial to compare two preparations with different concentrations

Oral lichen planus (OLP) is a chronic inflammatory disease that can be painful, mainly in the atrophic and erosive forms. Numerous drugs have been used with dissimilar results, but most treatments are empirical and do not have adequate control groups or correct study designs. However, to date, the most commonly employed and useful agents for the treatment of LP are topical corticosteroids. A randomized, double-blind, placebo-controlled trial has been designed to compare the efficacy and safety of two different formulations of clobetasol, a very potent topical steroid, in the topical management of OLP and to evaluate which gives the longest remission from signs and symptoms. Thirty-five consecutive patients were divided into two groups: the first received clobetasol propionate 0.025% and the second was given clobetasol propionate 0.05%. Both drugs were placed in 4% hydroxyethyl cellulose bioadhesive gel. Anti-mycotic prophylaxis was also added. After the end of therapy, patients received a 2-month follow-up. In all, 14 of the 15 clobetasol 0.025% patients (93%) and 13 of the 15 clobetasol 0.05% patients (87%), had symptoms improvement after 2 months of therapy (P = 0.001 in both groups). Also, 13 of the 15 clobetasol 0.025% patients (87%) and 11 of the 15 clobetasol 0.05% patients (73%) had clinical improvement after 2 months of therapy (P < 0.05 in both groups). No statistical differences were found in comparing the two different formulations. A larger concentration of the active molecules cannot further improve the therapeutic findings or optimize the obtained results in a significant manner.

Oral mucosal diseases: Mucous membrane pemphigoid

Subepithelial vesiculobullous conditions are chronic autoimmune disorders that arise from reactions directed against components of the hemidesmosomes or basement membrane zones (BMZ) of stratified squamous epithelium to which the term immune-mediated subepithelial blistering diseases (IMSEBD) has been given. Mucous membrane pemphigoid (MMP) is the most common, but variants do exist. Non-immune disorders that involve these epithelial components typically have a genetic basis--the main example being epidermolysis bullosa. All subepithelial vesiculobullous disorders present as blisters and erosions, and diagnosis must be confirmed by biopsy examination with immunostaining, sometimes supplemented by other investigations. No single treatment reliably controls all subepithelial vesiculobullous disorders; the immunological differences within IMSEBD may account for differences in responses to treatment. Currently, as well as improving oral hygiene, immunomodulatory treatment is used to control the oral lesions of MMP, but it is not known if its specific subsets reliably respond to different agents.

The efficacy of aloe vera gel in the treatment of oral lichen planus: a randomized controlled trial

BACKGROUND

Oral lichen planus (OLP) is a chronic inflammatory disease that can be painful especially in the atrophic and erosive forms. Several therapies have been tried, with varying results. There is one case report in which aloe vera (AV) was used successfully in the treatment of lichen planus.

OBJECTIVES

To compare the efficacy of AV and placebo in the topical management of OLP.

METHODS

A randomized, double-blind, placebo-controlled trial was designed. Fifty-four patients were randomized into two groups to receive AV gel or placebo for 8 weeks.

RESULTS

Fifty-four consecutive patients (34 women and 20 men) participated in the study. We found erosive and ulcerative lesions in 83% and 17%, respectively. The most common site of OLP was the lower lip. Twenty-two of 27 patients treated with AV (81%) had a good response after 8 weeks of treatment, while one of 27 placebo-treated patients (4%) had a similar response (P<0.001). Furthermore, two patients treated with AV (7%) had a complete clinical remission. Burning pain completely disappeared in nine patients treated with AV (33%) and in one treated with placebo (4%) (P=0.005). Symptomatology improved by at least 50% (good response) in 17 patients treated with AV (63%) and in two treated with placebo (7%) (P<0.001). No serious side-effects were found in both groups.

CONCLUSIONS

AV gel is statistically significantly more effective than placebo in inducing clinical and symptomatological improvement of OLP. Therefore, AV gel can be considered a safe alternative treatment for patients with OLP.

Oral mucosal disease: Lichen planus

Lichen planus (LP) is a common disorder in which auto-cytotoxic T lymphocytes trigger apoptosis of epithelial cells leading to chronic inflammation. Oral LP (OLP) can be a source of severe morbidity and has a small potential to be malignant. The diagnosis of OLP can be made from the clinical features if they are sufficiently characteristic, particularly if typical skin or other lesions are present, but biopsy is recommended to confirm the diagnosis and to exclude dysplasia and malignancy. OLP is treated with anti-inflammatory agents, mainly the topical corticosteroids, but newer agents and techniques are becoming available.

Effectiveness of two oral pastes for the treatment of recurrent aphthous stomatitis

OBJECTIVE

To compare the effectiveness of two topical medications to reduce the pain and size of recurrent minor aphthous ulcers.

SETTING

Ten Colombian Dental Faculties' clinics.

DESIGN

A double-blind randomized multi-centre clinical study.

SUBJECTS

Ninety-six patients complaining of at least five acute aphthous ulcers were randomized to two intervention groups. Sample size was calculated using an alpha error of 0.05 and beta of 0.20.

MATERIALS AND METHODS

Participants were randomly assigned to receive 5% amlexanox or a 0.05% clobetasol propionate magistral preparation. Observers at the participating institutions were previously trained to standardize clinical diagnosis and data recollection. Ulcer size and pain were measured on treatment days 0, 2 and 5.

RESULTS

No significant differences were found between the two groups studied in any of the studied variables at baseline. Both treatment medications significantly reduced pain magnitude and the index ulcer's size on days 2 and 5 compared with day 0 without adverse reactions (within groups differences). No statistical differences between groups of the study medications were found.

CONCLUSION

The two treatments applied had similar effectiveness as they both relieved pain and reduced the size of recurrent aphthous ulcers.

A randomized, placebo-controlled, double-blind clinical trial of curcuminoids in oral lichen planus

We studied the efficacy of curcuminoids in the treatment of oral lichen planus (OLP), a chronic, mucocutaneous, immunological disease. Curcuminoids are components of turmeric (Curcuma longa) that have anti-inflammatory activity. Turmeric has been used in Ayurveda (Indian traditional medicine) for centuries. A randomized, double-blind, placebo-controlled trial was conducted. In all, 100 consecutive, eligible patients with OLP presenting to the oral medicine clinic at the University of California, San Francisco, were to be selected. Two interim analyses were to be conducted during the trial. The trial was conducted between February 2003 and September 2004. The first interim analysis was conducted in October 2004 using data from the first 33 subjects. Study subjects were randomized to receive either placebo or curcuminoids at 2000 mg/day for 7 weeks. In addition, all subjects received prednisone at 60 mg/day for the first 1 week. The primary outcome was a change in symptoms from baseline. Secondary outcomes were changes in clinical signs and occurrence of side effects. The first interim analysis did not show a significant difference between the placebo and curcuminoids groups. Conditional power calculations suggested a less than 2% chance that the curcuminoids group would have a significantly better outcome as compared with the placebo group if the trial were continued to completion. Therefore, the study was ended early for futility. Reaching a conclusion regarding the efficacy of curcuminoids based on the results of this study is not possible as it was ended early for futility. Curcuminoids at this dose were well tolerated and the results suggest that for future studies a larger sample size, a higher dose and/or longer duration of curcuminoids administration should be considered; however, for the next step, an RCT of a shorter duration, using a higher dose of curcuminoids, and without an initial course of prednisone, should be considered.
