Oral pemphigus vulgaris: a review of the literature and a report on the management of 12 cases

Efficacy of anti-desmoglein 1 and anti-desmoglein 3 levels by enzyme-linked immunosorbent assay compared to biopsy of chronic oral ulcerative diseases with positive Nikolsky's sign to diagnose oral pemphigus vulgaris with or without skin involvement: a retrospective institutional observational pilot study

OBJECTIVE

We assessed the efficacy of anti-desmoglein 1 (anti-DSG1) and anti-DSG3 levels by enzyme-linked immunosorbent assay (ELISA) as a preliminary diagnostic test in the diagnosis of oral pemphigus vulgaris (OPV) with or without skin involvement compared to biopsy.

STUDY DESIGN

We retrospectively analyzed data collected from 23 patients (mean age 45.13 years) who had presented with chronic oral ulcerations, desquamative gingivitis, and a positive Nikolsky's sign. We performed ELISA, histopathologic examination, and direct immunofluorescence (DIF) and then calculated the sensitivity and specificity of the results of ELISA, histopathology, DIF, and the presence of a positive Nikolsky's sign in diagnosis.

RESULTS

The ELISA results showed that 18 patients had elevated anti-DSG3 levels, of whom 8 also had elevated anti-DSG1 levels. The histopathology results indicated that 18 patients had OPV, of whom 4 had oral lichen planus, and 1 had sub-epithelial blistering disease confirmed to be mucous membrane pemphigoid MMP by DIF. ELISA, histopathology, and DIF had a 100% sensitivity and specificity, and the presence of a positive Nikolsky's sign had a sensitivity and specificity of 100% and 78.26%, respectively.

CONCLUSIONS

Measurement of anti-DSG1 and anti-DSG3 levels by ELISA warrants consideration as a first-line diagnostic test for early detection of OPV with or without skin involvement over biopsy.

Liquid-based cytology for differentiating two cases of pemphigus vulgaris from oral squamous cell carcinoma

Pemphigus vulgaris (PV) is a rare autoimmune disease characterized by blisters on the skin and mucous membrane. Since it often appears in the oral mucosa first, it may be diagnosed by oral mucosal cytology. Although the cytologic finding is characterized by acantholytic cells, that is, Tzanck cells, it is important to distinguish PV from neoplastic lesions of the oral mucosal epithelium, including differentiation from atypical parabasal/basal cells, which appear in squamous cell carcinoma (SCC). In this study, we examined the cellular findings in two cases of PV and a case of well-differentiated SCC with loss of epithelial cell cohesion. The samples were prepared using liquid-based cytology, which showed small round-shaped and deeply stained atypical, orangeophilic keratinocytes not only in SCC but also in PV, which made differentiation between the two difficult. However, Tzanck cells found in PV differ from the deep atypical parabasal/basal cells of SCC, suggesting that the cell outline is indistinct and small protrusions and brush-like structures are observed. This feature of Tzanck cells may be useful in cytological judgment.

Oral Pemphigus Vulgaris Treatment with Corticosteroids and Azathioprine: A Long-Term Study in Shiraz, Iran

Background

Treating oral mucosal lesions of Pemphigus Vulgaris (PV) disease is usually challenging for clinicians. We studied the treatment outcomes of the oral PV patients referred to the Oral Medicine Department of Shiraz University of Medical Sciences from 2004 to 2018.

Methods

The medical records of 54 oral PV patients with histopathological confirmation who were treated by a single protocol were studied. The protocol consisted of initial treatment with 1 mg/kg/day of oral prednisolone for all patients. After 4–6 weeks, all patients were prescribed 40 mg of prednisolone. If lesion recovery was not observed or new lesions had developed, adjuvant therapy (maximum dose of 200 mg per day of Azathioprine (AZA)) was initiated anytime during the treatment. The oral prednisolone dosage was gradually tapered to 5 mg/alternate day in 9 months.

Results

47 patients were included in the study. 34.04% were male and 65.96% were female with a mean age of 41.83 ± 12.520. The mean follow-up period was 50.806 ± 44.417 months (over 4 years). The severity of oral involvement was mild in 21.27%, moderate in 36.17%, and severe in 42.6%. During treatment, all patients except one experienced complete remission. The mean time to achieve complete remission was 150.39 ± 224.075 days. Most of the patients experienced relapse due to self-discontinuation of treatment. 55% had complete remission and 43% were in partial remission at the last follow-up session. In 65.96% of patients, treatment-associated side effects were observed. The patients treated with prednisolone alone had significantly more side effects than those using AZA as an adjuvant (80% vs 50%, respectively; P=0.030). The mean duration of follow-ups was longer for patients with side effects (P < 0.01). Topical corticosteroids were used for all patients sometime during the treatment. No deaths were recorded.

Conclusion

Prescribing low-dose prednisolone and adding AZA in nonresponding cases has good clinical outcomes for the treatment of oral lesions of PV. Adjuvant therapy can avoid the increase in corticosteroid dosage and side effects. The treatment method described in this study can be a helpful guide for clinicians, especially when other immunosuppressive drugs are not available.

Immunoglobulin Disorders and the Oral Cavity: A Narrative Review

The oral mucosa is a mechanical barrier against the penetration and colonization of microorganisms. Oral homeostasis is maintained by congenital and adaptive systems in conjunction with normal oral flora and an intact oral mucosa. Components contributing to the defense of the oral cavity include the salivary glands, innate antimicrobial proteins of saliva, plasma proteins, circulating white blood cells, keratinocyte products of the oral mucosa, and gingival crevicular fluid. General disturbances in the level of immunoglobulins in the human body may be manifested as pathological lesions in the oral mucosa. Symptoms of immunoglobulin-related general diseases such as mucous membrane pemphigoid (MMP), pemphigus vulgaris (PV), linear IgA bullous dermatosis (LABD), Epidermolysis Bullosa Aquisita (EBA), and Hyper-IgE syndrome (HIES) may appear in the oral cavity. In this review, authors present selected diseases associated with immunoglobulins in which the lesions appear in the oral cavity. Early detection and treatment of autoimmune diseases, sometimes showing a severe evolution (e.g., PV), allow the control of their dissemination and involvement of skin or other body organs. Immunoglobulin disorders with oral manifestations are not common, but knowledge, differentiation and diagnosis are essential for proper treatment.

Pemphigus vulgaris presenting as esophageal ulceration. Report of an underdiagnosed manifestation

Pemphigus vulgaris (PV) is a rare autoimmune blistering disorder of the skin and mucous membranes. The true prevalence of esophageal involvement is unknown; esophageal symptoms almost always occur in the context of oral mucosa involvement. We report the case of a 66-year-old man with cutaneous blisters and esophageal symptoms that did not respond to acid suppression therapy. Esophagogastroduodenoscopy showed esophageal ulcers and mucosal desquamation. Biopsies were consistent with the diagnosis of PV. The patient was started on immunosuppressive therapy, achieving remission. This represents a rare case of esophageal involvement of PV without mucosal involvement and draws attention to a rare cause of dysphagia, which can be fatal if left untreated.

Chronic Oral Lesions

Chronic oral mucosal lesions can be associated with several mucocutaneous diseases. This article reviews the autoimmune and immune-mediated, reactive, genetic, and infectious diseases that may present with chronic oral and/or cutaneous manifestations and provides a rational approach to diagnosis and management.

World Workshop of Oral Medicine VII: A systematic review of immunobiologic therapy for oral manifestations of pemphigoid and pemphigus

OBJECTIVE

To assess the evidence for treatment of oral involvement of pemphigus and pemphigoid with biologics.

STUDY DESIGN

This systematic review used a comprehensive search strategy to identify literature describing oral involvement of pemphigus or pemphigoid treated with a biologic agent. The primary outcome measures were efficacy and safety of biologic therapy.

RESULTS

Inclusion criteria were met by 154 studies including over 1200 patients. Treatment of pemphigus with a total of 11 unique biologic agents and 3 unique combinations of agents is reported. Five randomized controlled trials (RCT) were included in the final analysis that investigated infliximab, IVIg, rituximab, and autologous platelet-rich plasma therapy for pemphigus vulgaris. Three non-RCT studies reported on successful rituximab or IVIg therapy for mucous membrane pemphigoid. Studies demonstrated considerable heterogeneity in agent, methods, and quality.

CONCLUSIONS

Evidence clearly describing oral tissue response to biologic therapy is sparse. Two RCTs support use of rituximab, one supports use of IVIg, and one pilot study suggests intralesional injection of autologous platelet-rich plasma aids healing of oral PV lesions. As oral lesions of pemphigus and pemphigoid can be refractory to systemic therapy, drug trials including biologic therapies should document details regarding response of the oral lesions to therapy.

Removable Prosthetic Treatment in Oral Pemphigus Vulgaris: Report of Three Cases

Pemphigus vulgaris (PV) is the most common clinical phenotype affecting the oral mucosa. Although rare, this vesicular disease may represent a severe complication in the management of edentulous or partially dentate patients because of the priority of care in handling the oral tissues. Analysis of the dental literature indicated a lack of evidence about the possibility of rehabilitating PV patients with removable prosthesis. Our study aimed to evaluate and describe the possibility of rehabilitating three patients who suffered from oral PV with removable prosthesis, although the friction of the prosthesis on oral soft tissues is one of the causes of the development of vesicular lesions which could break, causing oral mucosal pain and erosion. Three patients, referred to the Oral Pathology and Medicine section of the Dental School in Bari University, underwent biopsy, direct and indirect immunofluorescence tests, and enzyme-linked immunosorbent assay to confirm the diagnosis of oral PV. For each patient, a systemic corticosteroid therapy was planned. After the clinical remission of the PV signs, the patients were planned for an oral rehabilitation with removable prosthesis. As long as certain precautions are followed, patients with PV in a phase of clinical remission, induced by treatment, can be treated successfully with removable prosthesis. Although some authors have previously cautioned about the use of removable prosthesis for the treatment of patients with oral pemphigus, it is our view that, if patients follow the rigorous and periodic follow-up as discussed above, along with a corticosteroid immunosuppressive therapy, they may not show any deterioration of their clinical symptoms.

Dental Implant Rehabilitation in Patients Suffering from Mucocutaneous Diseases: A Systematic Review and Meta-Analysis

Objective:

Dental implantations are widely used for oral rehabilitation of edentulous patients. Despite high success rate, there are some risk factors that have been associated with failures. Oral mucocutaneous diseases are one of these risk factors for implant insertion due to the immunosuppressive therapy.

There are limited studies that have dealt with the subject of dental implantology in oral mucosal disorders mainly with patients with oral lichenplanus, pemphigoid, pemphigus vulgaris, and systemic lupus erythematosus. In order to assess the result of implantations in such patients, we have reviewed the studies.

Materials and Methods:

We searched PubMed, Science Direct, and Cochrane databases for articles published from Jan 2000 to Dec 2017, using key search word “dental implants”, “oral lichen planus”, “pemphigoid”, “pemphigus vulgaris” and ”systemic lupus erythematosus”.

Results:

The random effects analysis result shows overall failure rates of 22% in patients with oral lichen planus. A systematic review revealed some failures that are not definitely related to these diseases.

Conclusion:

Due to the lack of adequate studies, a meta-analysis was only possible for oral lichen planus. Presently, there is no definite guideline regarding the placement of implant in patients suffering from mucocutaneous diseases; nevertheless, we should always consider that these patients are specific cases and need more attention in the first step of treatment and follow-ups. So there is a need to further clinical studies in order to evaluate more risk factors accurately and make a definitive conclusion.

Pemphigus Vulgaris in the Mouth and Esophageal Mucosa

Pemphigus vulgaris (PV) is a chronic autoimmune mucocutaneous disease. In most cases, the initial manifestation occurs in the mouth as multiple ulcerations preceded by blisters that rupture and later spread to other mucous membranes and the skin. Esophageal impairment is rare. We report a case of PV with esophageal involvement in a 53-year-old woman who sought medical care, complaining of diffuse painful lesions in the oral cavity for approximately 1 month, with no improvement with nystatin. Upper digestive endoscopy (UDE) was performed with findings of vesiculobullous lesions in the proximal and middle esophagus, which were biopsied and for which histopathology confirmed PV in the esophageal mucosa. We draw attention to UDE as important for the diagnosis, and it should be indicated in patients with vesiculobullous lesions of the mouth, especially if there are esophageal complaints.

Autologous platelet-rich plasma and triamcinolone acetonide intralesional injection in the treatment of oral erosions of pemphigus vulgaris: a pilot study

Oral erosions of pemphigus vulgaris (PV) represent a therapeutic challenge. In this work we compared intralesional injection of steroids (ILS) and autologous platelet-rich plasma (PRP) treatment of oral erosions of PV. In this split-mouth randomized double blind study, one side of the buccal mucosa of 11 PV patients was injected with 10 mg/ml triamcinolone and the opposite side was injected with 1 millilitre of autologous PRP every 14 days for 3 months. The percentage of clinical improvement, pemphigus disease area index and pain score were recorded before and after therapy. Out of 11 recruited patients, only 9 completed the study. Seven out of the nine patients (78%) showed improvement in PDAI and/or pain score. The mean oral PDAI of the steroid injected sides decreased from 2.3 to 0.9. The mean oral PDAI of the PRP injected sides decreased from 2.6 to 1.0. No significant difference was detected in clinical improvement, PDAI and pain score between autologous PRP and ILS in the treatment of oral erosions of PV. Autologous PRP can be used for the treatment of resistant oral erosions of PV when ILS is contraindicated.

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.

Childhood Occurrence of Pemphigus

Pemphigus is a chronic mucocutaneous disease that initially manifests in the form of intraoral blisters which spread to other mucous membrane and skin. This study describes an unusual case of chronic generalized childhood pemphigus disease in an 11-year-old girl, who presented with multiple vesicles all over her body. Such a condition is seen more often in older people rather than children. It is crucial for dental professionals to be familiar with the diagnosis of bullous skin diseases in children and adolescents, especially in its initial stages in order to prevent the serious consequences and morbidity. The article highlights clinical presentation, histopathology, and successful management strategies useful for pediatric dental practice.

Pemphigus Vulgaris and Eosinophilic Esophagitis in a 13-Year-Old Boy: Case Report and Review of the Literature

This case report presents a 13-year-old boy referred to the Department of Paediatric Dentistry, Women's and Children's Hospital, Adelaide, South Australia, Australia, with a 5-week history of severe oral ulcerations and significant weight loss of unknown origin. The diagnosis of pemphigus vulgaris was made after histologic and immunofluorescent examination of an intraoral deep incisional biopsy, with eosinophilic esophagitis also diagnosed during the initial upper gastrointestinal endoscopy. The association between pemphigus vulgaris and eosinophilic esophagitis in this case, although previously unreported, is explicable on the basis of dysregulation of desmoglein 1 (DSG1). This case report identifies a new clinical association that could help clinicians identify further such cases and provides insight into the pathogenesis of both conditions.

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.

Management of Pemphigus Vulgaris

INTRODUCTION

Pemphigus vulgaris (PV) is a chronic, autoimmune, vesiculobullous disease. As a result of the relative rarity of PV, published randomized controlled trials (RCTs) are limited, which makes it difficult to evaluate the efficacy of different treatment regimens in this disease. This also precludes conduct of a meta-analysis.

METHODS

English-language publications describing treatment outcomes of patients with PV were identified by searches of electronic databases through May 2015, and additionally by review of the bibliography of these publications. A total of 89 papers, which included 21 case reports, 47 case series, 8 RCTs, and 13 observational studies, were identified. The findings from these publications, including information on disease course and prognosis, medications used, treatment responses, and side effects, are summarized in the tables and text of this review.

RESULTS

Prior to availability of corticosteroid therapy, PV had a high fatality rate. Early publications from the 1970s reported high-dose, prolonged corticosteroid use and significant associated side effects. Later reports described use of corticosteroids along with steroid-sparing adjuvants, which allows a reduction in the total dose of corticosteroids and a reduction in observed mortality and morbidity. For the majority of patients in these reports, a long-term course on medications lasting about 5-10 years was observed; however, subgroups of patients requiring shorter courses or needing longer-term therapy have also been described. Early diagnosis of PV and early initiation of treatment were prognostic factors. In recent publications, commonly used initial regimens include corticosteroids in combination with mycophenolate or azathioprine; whereas, for patients with inadequate response to these regimens, adjuvants such as intravenous immunoglobulin (IVIg) or rituximab are used.

CONCLUSION

The review findings emphasize the importance of early diagnosis, early initiation of treatment, and use of steroid-sparing adjuvants to allow a reduced total dose and duration on corticosteroids. Also highlighted is the need for more RCTs.

Clinical application of gancyclovir in the complex treatment of the different forms of true acantholytic pemphigus

Short summary and results of the own clinical observations on efficacy of developed complex method on the treatment of true acantholytic pemphigus composed of traditional immunosuppressive therapy and antiviral remedy - gancyclovir are presented. The etiology of herpesvirus infection had been discussed in the pathogenesis of the disease.

Palatal ulceration

Palatal ulcers are a common presentation and can be conveniently divided into developmental and acquired causes, the latter of which is subdivided into acute and chronic causes. Most commonly seen dermatologic causes have associated skin manifestations. Acute and multiple ulcers are usually infectious or drug induced in origin. Recurrent ulcers are largely dominated by aphthosis, while chronic ulcers are seen in immunocompromised patients and can occasionally be malignant. It is essential to involve the oral and maxillofacial surgeons early in the therapeutic management to tackle the inevitable complications that may ensue in the chronic cases.

Studying of the expression of PERP protein in the skin of patients with pemphigus

The authors disclosed the participation of apoptosis proteins in the development of acantholysis in patients with pemphigus. In this connection, studies of the PERP protein passing apoptosis signals and regulating desmosomal functions in keratinocytes are of interest. There is no information about any studies aimed at the PERP protein expression in patients with pemphigus in available literature. Goal. To assess the PERP protein expression in the skin of patients with pemphigus. Materials and methods. There was a study of 22 patients with pemphigus, a patient with bullous pemphigoid and ten healthy people. The PERP protein expression was studied in the biopsy materials obtained from lesion foci and apparently healthy skin of the patients as well as healthy people using the indirect immunofluorescence method. Results. The PERP protein expression was revealed in patients with pemphigus on areas of apparently intact skin, in lesion foci in the patient with bullous pemphigoid and skin of healthy volunteers in the membrane of keratinocytes from all epidermal layers.The PERP protein expression in the blister operculum in lesion foci in patients with pemphigus was absent. Conclusion. Substantial differences in the PERP protein expression in the blister operculum and apparently intact skin of patients with pemphigus were revealed.

Clinical and histological characterization of oral pemphigus lesions in patients with skin diseases: a cross sectional study from Sudan

Background

Pemphigus is a rare group of life-threatening mucocutaneous autoimmune blistering diseases. Frequently, oral lesions precede the cutaneous ones. This study aimed to describe clinical and histological features of oral pemphigus lesions in patients with skin disease has been canceled aged 18 years and above, attending outpatient’s facility of Khartoum Teaching Hospital - Dermatology Clinic, Sudan. In addition, the study aimed to assess the diagnostic significance of routine histolopathology along with immunohistochemical (IHC) examination of formalin-fixed, paraffin-embedded biopsy specimens in patients with oral pemphigus.

Methods

A cross-sectional hospital-based study was conducted from October 2008 to January 2009. A total of 588 patients with confirmed skin has been canceled disease diagnosis completed an oral examination and a personal interview. Clinical evaluations supported with histopathology were the methods of diagnosis. IHC was used to confirm the diagnosis. Location, size, and pain of oral lesions were used to measure the oral disease activity.

Results

Twenty-one patients were diagnosed with pemphigus vulgaris (PV), 19 of them (mean age: 43.0; range: 20–72 yrs) presented with oral manifestations. Pemphigus foliaceus was diagnosed in one patient. In PV, female: male ratio was 1.1:1.0. Buccal mucosa was the most commonly affected site. Exclusive oral lesions were detected in 14.2% (3/21). In patients who experienced both skin and oral lesion during their life time, 50.0% (9/18) had oral mucosa as the initial site of involvement, 33.3% (6/18) had skin as the primary site, and simultaneous involvement of both skin and oral mucosa was reported by 5.5% (1/18). Two patients did not provide information regarding the initial site of involvement. Oral lesion activity score was higher in those who reported to live outside Khartoum state, were outdoor workers, had lower education and belonged to Central and Western tribes compared with their counterparts. Histologically, all tissues except one had suprabasal cleft and acantholytic cells. IHC revealed IgG and C3 intercellularly in the epithelium.

Conclusions

PV was the predominating subtype of pemphigus in this study. The majority of patients with PV presented with oral lesions. Clinical and histological pictures of oral PV are in good agreement with the literature. IHC confirmed all diagnoses of PV.

Keratinization and its disorders

Keratins are a diverse group of structural proteins that form the intermediate filament network responsible for maintaining the structural integrity of keratinocytes. In humans, there are around 30 keratin families divided into two groups, namely, acidic and basic keratins, which are arranged in pairs. They are expressed in a highly specific pattern related to the epithelial type and stage of cellular differentiation. A total of 54 functional genes exist which codes for these keratin families. The expression of specific keratin genes is regulated by the differentiation of epithelial cells within the stratifying squamous epithelium. Mutations in most of these genes are now associated with specific tissue fragility disorders which may manifest both in skin and mucosa depending on the expression pattern. The keratins and keratin-associated proteins are useful as differentiation markers because their expression is both region specific and differentiation specific. Antibodies to keratin are considered as important tissue differentiation markers and therefore are an integral aid in diagnostic pathology. The present review discusses the structure of keratin, the various types of keratin and their distribution and the disorders associated with keratinization with special emphasis on the disorders of the oral cavity. A brief note on the clinical significance of keratin is also mentioned.

Current concepts of immunofluorescence in oral mucocutaneous diseases

Aim:

To study the immunofluorescence pattern and to assess its reliability as a confirmatory diagnostic test in patients with pemphigus, pemphigoid, lichen planus, and lupus erythematosus and also to assess the disease activity by indirect immunofluorscence (IIF) in patients with pemphigus only.

Materials and Methods:

Twenty-six patients were included in the study group, out of which, 6 patients were clinically and histopathologically diagnosed as pemphigus, completely free of active lesions were subjected to IIF only to assess the disease activity and were grouped separately. Based on the clinical and provisional diagnosis, the remaining 20 patients who had active lesions were subjected to direct immunofluorscence (DIF) and IIF and were divided into four groups. Biopsy specimens were taken from the periphery of the lesions and were examined by both conventional light microscopic and DIF methods. Five milliliters of venous blood was collected from each patient and were subjected to IIF.

Results:

Histopathological diagnosis was consistent with direct immunofluorescence study in 15 cases (75%). The various immunofluorescence patterns observed in our study were consistent with those described by various authors in standard textbooks and articles.

Conclusion:

Histopathology remains gold standard for most of the diseases, it is recognized from this study that not all lesions are amenable to definitive histopathological diagnosis thus; DIF can provide a valuable additional criterion in diagnosis.

Gingival pemphigus vulgaris preceding cutaneous lesion: A rare case report

Pemphigus is a group of autoimmune diseases characterized by formation of intraepithelial bullae in skin and the mucous membrane. Pemphigus vulgaris affects the oral mucosa in nearly all cases. Pemphigus vulgaris is characterized by auto antibodies directed against desmosome-associated protein antigens (desmoglein-3) found in epithelial and epidermal intercellular substance. We report here a case of pemphigus vulgaris of gingiva in an adult female patient at an early stage followed by dermatologic involvement. Perilesional incision was taken and histopathological and direct immunofluorescence was done for identification of specific antibodies. The oral lesions were treated with 0.1% Triamcinolone acetonide ointment and Prednisolone 20 mg twice daily with multivitamins was administered systemically for skin lesion.

Pemphigus pathogenesis: problems and prospects

Provides the survey of most prospective trends of research of the pathogenesis of the true acantholytic pemphigus. Cites key results of studies of factors of genetic predisposition to the development of this bullous dermatosis. Highlights problems of studies of the role of antiself antibodies and self-antigens in pemphigus pathogenesis. Represents the apoptolyse theory, explaining mechanisms of the loss of link between keratinocytes. Discusses issues of the cellular regulation of autoimmune reactions at acantholytic pemphigus.

Analysis of current therapy and clinical outcome in childhood pemphigus vulgaris

Pemphigus vulgaris (PV) is a rare, potentially fatal chronic autoimmune disease of the skin and mucous membrane. The objective of this study was to analyze the clinical outcomes and side effects associated with treatment of childhood PV (CPV). A retrospective review of the English language literature was conducted through PUBMED using the words childhood pemphigus vulgaris, and treatment or clinical outcome. Only patients under 12 years of age were included. Thirty-three cases were found in 29 reports. Mean age at onset was 8.3 years (range 1.5-12 yrs). Mucosal involvement (97.0%) was more common than cutaneous involvement (84.8%). Oral mucosa was the most common site of mucosal involvement (93.9%), followed by genital (20.6%), ocular (11.8%), and nasal mucosa (2.9%). Mean duration of therapy was 4.5 years (range 0.6-14.5 yrs), and mean duration of follow-up was 5.2 years (range 0.6-16 yrs). Complete recovery with no further therapy was achieved in 18.2% and partial recovery with minor relapses while on maintenance therapy in 78.8%. One patient died due to infection (3.0%). Serious side effects were present in 60.6%. The most common were cushingoid features (65.0%), growth retardation (50.0%), and infection (50.0%). Two patients who were refractory to systemic corticosteroids and immunosuppressive agents (ISA) had a favorable clinical response to Rituximab. Current therapy for CPV involving the use of long-term systemic corticosteroids in conjunction with ISA results in prolonged immunosuppression, causing systemic infections and growth retardation. Safer and more effective therapies need to be explored.

Severe manifestation of oral pemphigus

This article describes a case of pemphigus vulgaris in a relatively young patient with exacerbated characteristics, widespread lesions, and rapid evolution. A 40-year-old woman sought treatment, complaining about severe oral pain and dysphagia. Intraoral inspection revealed ulcerated lesions on the lips, buccal mucosa, and floor of the mouth. The number of lesions quickly increased and resembled erythema multiforme. She also presented blistering lesions on the back, abdomen, neck, and eyes. Incisional oral biopsy revealed pemphigus vulgaris. This report emphasizes the importance of early diagnosis of an oral biopsy in systemic diseases and the management of the lesions.

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.

Early invasive vulvar squamous cell carcinoma arising in a woman with vulvar pemphigus vulgaris and systemic lupus erythematosus

BACKGROUND

Pemphigus vulgaris (PV) is an autoimmune blistering disease of the skin and mucous membranes. Genital involvement occurs when most other common sites are concurrently affected or are in remission. Systemic lupus erythematosus (SLE) is an autoimmune disease that may affect many parts of the body and the skin with occasional bullous lesions. Pemphigus vulgaris and SLE may be associated, albeit rarely. Here, we report the first case of a woman affected with SLE presenting with early invasive squamous cell carcinoma (SCC) arising from Pemphigus Vulgaris of the vulva.

CASE PRESENTATION

A 27-year-old Caucasian woman was admitted to our Gynaecology Unit for bleeding vegetant lesions of the vulva. Her history was characterized by systemic lupus erythematosus and PV. Biopsy showed concomitant PV and vulvar intraepithelial neoplasia (VIN) grade 3. One month later a new biopsy revealed progression from VIN 3 to early SCC. Despite chemotherapy, no remission of disease was observed. She died six months after diagnosis

CONCLUSION

Our case underlines PV as another chronic inflammatory disease of the lower genital tract predisposing to VIN-SCC. It suggests the need for careful follow-up of patients with chronic inflammatory disease, especially when concomitant autoimmune disorders are present. Moreover, a biopsy should be always performed if there are PV lesions because of the possibility of neoplastic disease.

Oropharyngeal pemphigus vulgaris and clinical remission: a long-term, longitudinal study

BACKGROUND

The pattern of clinical remission in pemphigus vulgaris patients still remains a controversial issue because of the limited data reported in the literature.

OBJECTIVE

To evaluate the time to clinical remission in patients with exclusive oropharyngeal pemphigus vulgaris.

METHODS

We conducted a long-term, longitudinal study in a university hospital. We treated 37 patients with oropharyngeal pemphigus vulgaris, who underwent a periodic follow-up for an average of 5.3 years, and evaluated their outcome in terms of clinical remission. The main outcome measure was the clinical outcome (assessed by objective measures of severity, extent of disease, intensity of therapy, and remission) before and after conventional immunosuppressive therapy.

RESULTS

Complete and long-lasting clinical remission was achieved in 35 patients (94.6%) with oropharyngeal lesions, of whom 13 (35.1%) were off therapy and 21 (56.8%) were on therapy at the last evaluation. One patient (2.7%) died following a stroke 3 years after complete remission on therapy. Partial remission was achieved in two patients (5.4%). The mean time to achieve complete clinical remission was 4.7 +/- 2.57 months after commencement of therapy. In all patients the mean disease severity score decreased from 7.81 +/- 1.35 at time of diagnosis to 1.0 +/- 0.9 at time of clinical remission (p < 0.0001 vs baseline), while the extent of the disease decreased from 2.9 +/- 1.0 to 0.27 +/- 0.45 (p < 0.0019 vs baseline) and the intensity of therapy from 4.91 +/- 0.64 to 0.70 +/- 0.57 (p < 0.0001 vs baseline). The mean duration of complete remission was 63.53 +/- 44.9 months.

CONCLUSIONS

In almost all patients with oropharyngeal pemphigus vulgaris it was possible to schedule a safe tapering of the conventional immunosuppressive therapy very shortly after the disease was controlled. Thus, we may conclude that: (i) the percentage of patients with oropharyngeal pemphigus vulgaris who achieved complete long-lasting clinical remission was very high; (ii) transient lesions that healed within a week were very frequent and had to be actively controlled; (iii) if treated early, most patients had a good clinical response and could achieve a disease- and drug-free clinical remission; (iv) early treatment may prevent extension or progression of disease; (v) there is a possible role for immunosuppressive agents; and (vi) a more favorable course of the disease, in terms of attainment and duration of clinical remission and a better prognosis, seemed to be related to a rapid response to therapy rather than to the initial severity and extent of the disease.

A current review of juvenile pemphigus vulgaris: analysis of data on clinical outcomes

Forty-seven cases of juvenile pemphigus vulgaris have been reported in the English literature. Histology of lesional skin and direct immunofluorescence of perilesional skin are both necessary for a complete diagnosis. The autoimmune bullous condition can affect the skin and mucous membranes individually, but typically affects both concurrently. Disease characteristics in juvenile patients are similar to those in adults; however, a disruption of biologic and social development is of particular concern during adolescence. Although systemic corticosteroids have been used to successfully treat the disease in most cases, long-term use is often necessary for adequate control. Adverse effects from therapy can have devastating effects during this critical period of hormonal changes, physical and mental growth, and social and cultural development that occurs during adolescence. Newer therapies must be designed to adequately treat juvenile patients while also limiting serious adverse effects.

Epidemiologic survey of pemphigus vulgaris with oral manifestations in northern Greece: retrospective study of 129 patients

OBJECTIVE

To evaluate the epidemiology of pemphigus vulgaris (PV) in a Greek population and to compare it with other countries.

MATERIALS AND METHODS

A retrospective study was conducted based on the records of 129 patients (41 males and 88 females) with PV who visited the Department of the Oral Medicine and Maxillofacial Pathology, Aristotle University of Thessaloniki, Greece and the State Hospital for Skin and Venereal Diseases of Thessaloniki, Greece, between 1985 and 2004. A group of 73 individuals was used as controls.

RESULTS

The average annual incidence was found to be eight patients per year. The male to female ratio was 1 : 2.25. The difference in the age of onset between the two genders was statistically significant in marginal levels (P = 0.05). In addition, 86.1% of the patients showed oral lesions only, 13.3% oral and skin lesions and 1.3% manifested oral, skin, and ocular lesions. Twenty-eight of the 88 females were in the premenopausal period-of-life. Additionally, 19 males were farmers who had daily contact with organophosphoric pesticides. Co-existing pathologic conditions were present in 75 of the 129 patients, and of these 75 patients six (8%) were diabetics, 15 (20%) presented with hypertension, two (2.6%) faced problems from their thyroid gland, and 10 (13.3%) of the patients complained of allergic reactions.

CONCLUSIONS

The results of this study demonstrated a relatively high incidence of PV in northern Greece compared with that in other countries. The disease most frequently occurred in the sixth decade-of-life and the majority of the patients manifested oral lesions. Further epidemiological studies are needed to elucidate whether this region is constituted from population groups with high susceptibility to PV.

Bullous dermatoses in childhood: part I

A classification of bullous dermatoses in childhood is presented, according to the histologic location of the bulla and the heritability of the disease, combined with the most recent laboratory examinations used in dermatologic practice. For a better understanding of the proposed classification, the authors also present a review of this group of diseases, which vary greatly within the group. In this first part of the classification and review, the group of bullous dermatoses with nonhereditary characteristics and intraepidermal cleavage is described.

Characterization of oral pemphigus vulgaris in Thai patients

Pemphigus vulgaris (PV) is a serious mucocutaneous disease that be fatal if left untreated. The oral mucosa is often the first site to be affected by the disease. It is thus important that the dentist is able to recognize oral manifestations of PV and refer appropriately. Although oral PV is a well-characterized condition, the disease characteristics of patients in Thailand have not been previously reported. Here, we describe patient and lesion characteristics of 18 cases of oral PV. For these 18 cases, the mean age was 38 years, and the male:female ratio was 1:2. The most commonly affected sites were the gingiva and buccal mucosa, and the duration of disease was approximately one year. Medications previously used included corticosteroids and interferon, and nine patients reported systemic disease. Histopathologic examination with/without direct immunofluorescence was the method of diagnosis in all cases.

Involvement of the Female Genital Tract in Pemphigus Vulgaris

BACKGROUND

Involvement of the genital tract in women with pemphigus vulgaris has rarely been reported. We report 34 patients with pemphigus vulgaris who have involvement of the vulva, vagina, or both.

METHODS

We reviewed the clinical data on 34 women treated at a tertiary dermatology referral center from July 1988 to June 2005.

RESULTS

Of 34 patients, 21 had labial involvement, 3 had vaginal involvement, and 10 had both labial and vaginal involvement. The mean age of onset of pemphigus vulgaris was 49 years. All patients had pemphigus vulgaris involvement at multiple other sites, and all had other mucous membrane involvement, most commonly oral (97%). Recurrent episodes of genital pemphigus vulgaris were noted in 35%, with a mean of 6 recurrences (range 1-11). In all the patients the pemphigus vulgaris was controlled with systemic and local therapy. Long-term follow-up for a mean of 76 months (range 9-204) indicated that no long-term sequela occurred due to genital involvement.

CONCLUSION

Involvement of the female genital tract in pemphigus vulgaris is rare. Vulvar lesions occur more commonly than vaginal lesions. With appropriate topical and systemic therapy, patients can have full recovery with no sequelae.

LEVEL OF EVIDENCE

II-3.

Gingival lesions as a first symptom of pemphigus vulgaris in pregnancy

The erosive gingival lesions associated with vesiculobullous diseases can be an important early clinical manifestation of serious diseases such as pemphigus vulgaris (PV). PV is a vesiculobullous disease of the skin and mucosa which tends to be chronic and which normally affects people of 40-60 years of age. Its incidence varies from 0.5 to 3.2 cases per 100,000 per year. Mucosal lesions are located mainly in the oral and pharyngeal mucosa, although conjunctiva, larynx, nasal mucosa, vulva, vagina, cervix, and ano-rectal mucosa may also be involved. It is a serious mucocutaneous disease of an autoimmune nature, whose appearance during pregnancy is extremely rare.

Oral pemphigus vulgaris in children and adolescents: a review of the literature and a case report

This paper describes a case of oral pemphigus vulgaris (PV) in a child that was diagnosed in its early stages and managed successfully. The authors also report a literature review. Although oral PV in children and adolescents is extremely rare, it should be included in the differential diagnosis of oral ulcerative disease. It is of utmost importance to diagnose PV in children and adolescents in its initial stages in order to prevent the serious morbidity that may result from the disease, and to institute phamacotherapeutic measures so that they have the greatest effect. Furthermore, it is essential for dentists to be aware of the existence of PV in child and adolescent patients so that they may refer such cases for specialist management without undue delay.

Number II Pemphigus vulgaris

Pemphigus is a group of potentially life-threatening autoimmune diseases characterized by cutaneous and/or mucosal blistering. Pemphigus vulgaris (PV), the most common variant, is characterized by circulating IgG antibodies directed against desmoglein 3 (Dsg3), with about half the patients also having Dsg1 autoantibodies. There is a fairly strong genetic background to pemphigus with linkage to HLA class II alleles and ethnic groups such as Ashkenazi Jews and those of Mediterranean and Indian origin, are especially liable. Oral lesions are initially vesiculobullous but readily rupture, new bullae developing as the older ones rupture and ulcerate. Biopsy of perilesional tissue, with histological and immunostaining examination are essential to the diagnosis. Serum autoantibodies to either Dsg1 or Dsg3 are best detected using both normal human skin and monkey oesophagus or by enzyme-linked immunosorbent assay. Before the introduction of corticosteroids, PV was typically fatal mainly from dehydration or secondary systemic infections. Current treatment is largely based on systemic immunosuppression using corticosteroids, with azathioprine or other adjuvants or alternatives but newer therapies with potentially fewer adverse effects, also appear promising.

Early Detection and Successful Management of Oral Pemphigus Vulgaris: A Case Report

BACKGROUND

Pemphigus vulgaris (PV) is an autoimmune disease characterized by acantholysis in the epithelium. PV is often difficult to diagnose in the early stages, since the oral lesions are relatively nonspecific. We report on a case with a favorable outcome due to early diagnosis and effective treatment of oral lesions.

METHODS

A 53-year-old Japanese woman presented with a month-long history of painful gingiva. PV was diagnosed using clinical, histopathological, and direct immunofluorescence criteria 1 month after the first visit. Evaluation of the circulating autoantibody titers to desmoglein (Dsg)1 and Dsg3 was conducted by enzyme-linked immunosorbent assay (ELISA). Occlusive steroid therapy (OST) using a topical corticosteroid (0.1% triamcinolone acetonide) was provided for 8 weeks. After OST was completed, a buccal frenectomy was performed to eliminate localized toothbrushing trauma.

RESULTS

There were no adverse effects on wound healing after the procedure. No oral PV lesions were detectable at the 9-month reevaluation, and the patient remains in complete remission. The Dsg1 ELISA was negative while the Dsg3 ELISA was indeterminate at the first visit. The Dsg1 ELISA was also negative at reevaluation, but Dsg3 ELISA reactivity had increased 9 months after completion of treatment.

CONCLUSION

Large scale clinical trials will be required to validate the clinical benefits of the OST treatment regimen, and further research is necessary to determine the importance of ELISA antibody examination in long-term management of oral PV.

Diagnosis of periodontal manifestations of systemic diseases

Many systemic diseases can mimic periodontitis or gingivitis. These include many immunologic, infectious, neoplastic and metabolic disorders. In comparison with periodontitis and gingivitis, these disorders are considerable less common. However, since their diagnosis and management differ, a high index of suspicion is frequently needed when confronted a patient presenting with gingival or periodontal disease. This chapter has reviewed a number of systemic conditions that may mimic clinically both gingivitis and chronic periodontitis and has focused on the features that may assist the clinician in making the diagnosis and providing specific therapies.
