Abstract
Background. Pemphigus vulgaris (PV) is an autoimmune blistering disease of the skin and mucosa. Anal mucosa may be involved in PV, but the frequency and clinical profile are not fully ascertained. Objective. The aim was to investigate the involvement of the anal area in newly diagnosed PV patients. Patients and Methods. A total of 168 consecutive newly diagnosed PV patients were enrolled. Anal symptoms and signs, involvement of other body sites, and severity of disease were recorded. Results. A total of 47 out of 168 patients (27.9%) had involvement of the anal area. Anal involvement was significantly associated with PV lesions in ophthalmic (P = 0.03), nasal (P = 0.02), and genital mucosa (P < 0.001) but not the oral cavity (P = 0.24). There was a significant association between number of involved mucosal sites and anal involvement (P < 0.001). Anal involvement was associated with oral severity (P = 0.02). Constipation was the most frequent symptom (73.8%) followed by pain on defecation (50%). Seventeen patients (36%) were symptom-free. Erosion was the most frequent sign (91.5%). Conclusion. Anal involvement in PV seems to be more frequent than previously assumed. Routine anal examination is recommended even in asymptomatic patients as anal involvement appears to correlate with the severity of PV.

Ann Dermatol Venereol 2013; 140:531-4. [PMID: 24034638 DOI: 10.1016/j.annder.2013.04.073] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2013] [Revised: 03/26/2013] [Accepted: 04/10/2013] [Indexed: 11/19/2022]
Abstract
BACKGROUND It has been reported that D-penicillamine causes pemphigus that is typically superficial. Immunostaining with monoclonal anti-32-2B antibody targeting desmoglein 1 and 3 can help differentiate between drug-induced and classical auto-immune pemphigus. Absence of specific staining militates in favour of drug-induced pemphigus whilst positive staining suggests an auto-immune aetiology that is ongoing despite discontinuation of drug therapy. PATIENTS AND METHODS A 59-year-old male patient was referred for management of superficial pemphigus 1 year after starting D-penicillamine treatment for scleroderma. The diagnosis of pemphigus was confirmed histologically (intra-epidermal cleavage, acantholysis and perikeratinocytes, deposition of IgG and complement C3). Immunochemical staining with anti-32-2B antibody was initially normal, in keeping with drug-induced pemphigus. Despite discontinuation of D-penicillamine, pemphigus recurred in 2008. A further skin biopsy was undertaken and anti-32-2B staining was abnormal, which is consistent with auto-immune pemphigus. DISCUSSION Numerous cases of drug-induced pemphigus have been described in the literature. In approximately half of all cases, the pemphigus recedes after cessation of the causative drug. However, there have been no previous reports that changes over time in the immunostaining with anti-32-2B antibodies can mirror a change in form of pemphigus from a drug-induced type to an idiopathic type as well as the associated clinical feature of persistence after drug withdrawal. CONCLUSION Normal staining with anti-32-2B antibody is associated with a favourable prognosis as regards resolution of drug-induced pemphigus. When, as in this case, status changes to abnormal staining, there is a risk that the pemphigus may become chronic despite discontinuation of therapy.

Genome-wide expression analysis suggests unique disease-promoting and disease-preventing signatures in Pemphigus vulgaris. Genes Immun 2013; 14:487-99.

Abstract
To evaluate pathogenetic mechanisms underlying disease development and progression in the autoimmune skin disease Pemphigus vulgaris (PV), we examined global peripheral blood gene expression in patients and healthy controls. Our goals were to: (1) assign blood gene expression signatures to patients and controls; (2) identify differentially expressed genes (DEGs) and investigate functional pathways associated with these signatures; and (3) evaluate the distribution of DEGs across the genome to identify transcriptional 'hot spots'. Unbiased hierarchical clustering clearly separated patients from human leukocyte antigen (HLA)-matched controls (MCRs; 'disease' signature), and active from remittent patients ('activity' signature). DEGs associated with these signatures are involved in immune response, cytoskeletal reorganization, mitogen-activated protein kinase (MAPK) signaling, oxidation-reduction and apoptosis. We further found that MCRs carrying the PV-associated HLA risk alleles cluster distinctly from unmatched controls (UMCR) revealing an HLA-associated 'control' signature. A subset of DEGs within the 'control' signature overlap with the 'disease' signature, but are inversely regulated in MCR when compared with either PV patients or UMCR, suggesting the existence of a 'protection' signature in healthy individuals carrying the PV HLA genetic risk elements. Finally, we identified 19 transcriptional 'hot spots' across the signatures, which may guide future studies aimed at pinpointing disease risk genes.

Abstract
The development of nonhormonal treatment of pemphigus vulgaris (PV) has been hampered by a lack of clear understanding of the mechanisms leading to keratinocyte (KC) detachment and death in pemphigus. In this study, we sought to identify changes in the vital mitochondrial functions in KCs treated with the sera from PV patients and healthy donors. PV sera significantly increased proton leakage from KCs, suggesting that PV IgGs increase production of reactive oxygen species. Indeed, measurement of intracellular reactive oxygen species production showed a drastic increase of cell staining in response to treatment by PV sera, which was confirmed by FACS analysis. Exposure of KCs to PV sera also caused dramatic changes in the mitochondrial membrane potential detected with the JC-1 dye. These changes can trigger the mitochondria-mediated intrinsic apoptosis. Although sera from different PV patients elicited unique patterns of mitochondrial damage, the mitochondria-protecting drugs nicotinamide (also called niacinamide), minocycline, and cyclosporine A exhibited a uniform protective effect. Their therapeutic activity was validated in the passive transfer model of PV in neonatal BALB/c mice. The highest efficacy of mitochondrial protection of the combination of these drugs found in mitochondrial assay was consistent with the ability of the same drug combination to abolish acantholysis in mouse skin. These findings provide a theoretical background for clinical reports of the efficacy of mitochondria-protecting drugs in PV patients. Pharmacological protection of mitochondria and/or compensation of an altered mitochondrial function may therefore become a novel approach to development of personalized nonhormonal therapies of patients with this potentially lethal autoimmune blistering disease.

Abstract
Pemphigus vulgaris (PV) is a paradigm of autoimmune disease affecting intercellular adhesion. The mechanisms that lead to cell-cell detachment (acantholysis) have crucial therapeutic implications and are currently undergoing major scrutiny. The first part of this review focuses on the classical view of the pathogenesis of PV, which is dominated by the cell adhesion molecules of the desmosome, namely desmogleins (Dsgs). Cloning of the DSG3 gene, generation DSG3 knock-out mice and isolation of monoclonal anti-Dsg3 IgG have aided to clarify the pathogenic mechanisms of PV, which are in part dependent on the fate of desmosomal molecules. These include perturbation of the desmosomal network at the transcriptional, translational, and interaction level, kinase activation, proteinase-mediated degradation, and hyper-adhesion. By the use of PV models, translational research has in turn helped shed light into the basic structure, function, and dynamics of assembly of desmosomal cadherins. The combined efforts of basic and applied research has resulted in tremendous advance into the understanding of epidermal adhesion and helped debunk old myths on the supposedly unique role of desmogleins in the mechanisms of cell-cell detachment in PV.

Abstract
BACKGROUND There are two main clinical subsets of pemphigus: pemphigus vulgaris and pemphigus foliaceus. Clinical and epidemiological changes related to both types of pemphigus have been observed in the last years. OBJECTIVES To analyze a 21-year historical case series of pemphigus vulgaris and pemphigus foliaceus in the northeast region of the state of Sao Paulo, where pemphigus foliaceus is endemic. METHODS In this descriptive study, data related to annual incidence and age of onset of symptoms compatible with pemphigus vulgaris or pemphigus foliaceus were analyzed, comparing both forms, in the period from 1988 to 2008. RESULTS The overall results cover a period of 21 years, with 103 cases of pemphigus vulgaris and 163 cases of pemphigus foliaceus. An evaluation of the trend lines regarding incidence has shown that pemphigus foliaceus is decreasing while pemphigus vulgaris is increasing. There was great variation in the age ranges, with persistence of the minimum range, from 10 to 20 years old, for pemphigus foliaceus (mean age = 32.1 years old), and clear downward in the minimum age for pemphigus vulgaris (mean age = 41.5 years old), especially from the middle of the first decade of the total period studied. CONCLUSION The incidence of pemphigus vulgaris has been exceeding that of pemphigus foliaceus since 1998. The results of this case series comprehending 21 years corroborate the change in the epidemiology of both clinical forms of pemphigus in Brazil, raising new hypotheses for their etiology and pathogenesis.

Abstract
Background: Pemphigus vegetans is a rare variant of pemphigus vulgaris, comprising 1 to 2% of all pemphigus cases. Exposures to oral agents such as captopril and penicillamine and, less commonly, physical or chemical factors have been implicated in the development of pemphigus. Methods: We report a 42-year-old white male with a 12-month history of hypertrophic, vegetative plaques affecting primarily his external nares and upper lips. The patient had a history of alcoholism and intermittent drug abuse, primarily intranasal cocaine, since his youth. He had been using cocaine heavily three to four times/week for 1 month prior to and 1 month following the onset of the eruption but has since ceased use. His clinical features and histopathologic findings were consistent with a diagnosis of pemphigus vegetans. Treatment with high-dose prednisone (80 mg/d) and mycophenolate mofetil (1.5 g/d) resulted in resolution of the lesions after 18 months. Results and Conclusions: To our knowledge, this is the second report proposing an association between intranasal cocaine use and the pemphigus family of disorders. Although the relationship between illicit drug use and the development of pemphigus is unclear, we postulate that intranasal cocaine abuse is operative in our patient's disease. Herein we discuss drug and other external precipitants of pemphigus and review previous case reports of pemphigus associated with illicit drugs. Renseignements de base: Le pemphigus végétant est une variante rare du pemphigus vulgaire, comptant pour 1 à 2 % de tous les cas de pemphigus. Un rapprochement a été établi entre l'exposition à des agents oraux tels que le captopril et la pénicillamine et, moins couramment, à des facteurs physiques ou chimiques, dans le développement du pemphigus. Méthodes: Nous exposons le cas d'un homme de race blanche âgé de 42 ans ayant des antécédents de plaques végétatives hypertrophiques pendant 12 mois, touchant principalement ses narines externes et ses lèvres supérieures. Le patient avait des antécédents d'alcoolisme et de consommation intermittente de drogues, principalement de la cocaïne prise par voie intranasale, depuis sa jeunesse. Il avait consommé de façon excessive de la cocaïne trois à quatre fois par semaine pendant le mois qui avait précédé et avait suivi l'apparition de l'éruption, mais il a depuis ce temps cessé d'en user. Ses caractéristiques cliniques et les résultats histopathologiques correspondaient à un diagnostic de pemphigus végétant. Le traitement consistant en la prise de fortes doses de prednisone (80 mg/j) et de mycophenolate mofetil (1,5 g/j) a entraîné la résorption des lésions après 18 mois. Résultats et conclusions: À notre connaissance, ce rapport est le deuxième qui propose l'existence d'une association entre la consommation de cocaïne par voie intranasale et le groupe de maladies pemphigus. Bien que la relation entre la consommation de drogues illicites et le développement du pemphigus ne soit pas claire, nous postulons que la consommation de cocaïne par voie intranasale a une incidence sur la maladie de notre patient. Nous discutons aux présentes des drogues et d'autres déclencheurs externes du pemphigus et nous examinons les rapports de cas antérieurs de pemphigus associé à la consommation de drogues illicites.

Abstract
Summary Background Several studies have reported that HLA-DRB1 may be correlated with pemphigus vulgaris (PV), but most have been based on small samples and the results remain inconsistent and unclear. Objectives To investigate the correlation between DRB1 and PV by a meta-analysis of case–control/nonfamily studies. Methods PubMed, Wiley Online Library, ScienceDirect, Google Scholar, Cochrane Library, Chinese National Knowledge Infrastructure and Wanfang databases were searched for studies including: (i) ‘pemphigus’; and (ii) ‘human leukocyte antigen’, ‘HLA’, ‘major histocompatibility complex’, ‘MHC’ or ‘DRB1’. Eighteen selected studies were used in meta-analyses to evaluate DRB1 alleles and phenotypes by calculating the respective odds ratios (ORs) and 95% confidence intervals (CIs). Stratified meta-analyses and meta-regression analysis were also conducted. Results The frequencies of three genotypes (allele and phenotype, respectively) were significantly increased in PV: DRB1*04 [P-value for comparability (Pc) < 0·00001, OR 3·61, 95% CI 2·28–5·71; Pc = 0·0002, OR 4·14, 95% CI 1·98–8·65], DRB1*08 (Pc = 0·03, OR 2·25, 95% CI 1·07–4·70; Pc = 0·0003, OR 2·46, 95% CI 1·51–4·01) and DRB1*14 (Pc < 0·00001, OR 6·47, 95% CI 4·52–9·26; Pc < 0·00001, OR 9·68, 95% CI 4·47–20·98). Three others (allele and phenotype, respectively) were significantly decreased in PV: DRB1*03 (Pc < 0·00001, OR 0·28, 95% CI 0·19–0·41; Pc = 0·0001, OR 0·25, 95% CI 0·12–0·51), DRB1*07 (Pc = 0·004, OR 0·45, 95% CI 0·26–0·78; Pc = 0·0002, OR 0·27, 95% CI 0·14–0·54) and DRB1*15 (Pc = 0·001, OR 0·35, 95% CI 0·18–0·66; Pc = 0·002, OR 0·32, 95% CI 0·16–0·65). Ethnicity partially explained the heterogeneity of DRB1*07, DRB1*08 and DRB1*14 phenotypes. Conclusions Our findings suggest that DRB1*04, DRB1*08 and DRB1*14 are statistically significant susceptibility factors for PV. Conversely, DRB1*03, DRB1*07 and DRB1*15 may be negatively associated with PV. Specific HLA-DRB1 types may influence the susceptibility or resistance to PV, which needs further investigations.

Abstract
Pemphigus vulgaris (PV) is a severe autoimmune blistering disease caused by anti-epithelial antibodies, leading to disruption of cell-cell adhesion. Although the disease is exceedingly rare worldwide, it is known to be relatively prevalent in Jewish populations. The low prevalence of the disease represents a significant obstacle to a genome-wide approach to the mapping of susceptibility genes. We reasoned that the study of a genetically homogeneous cohort characterized by a high prevalence of PV may help exposing associated signals while reducing spurious results due to population sub-structure. We performed a genome-wide association study using 300K single-nucleotide polymorphisms (SNPs) in a case-control study of 100 PV patients of Jewish descent and 397 matched control individuals, followed by replication of significantly associated SNPs in three additional cohorts of Jewish, Egyptian, and German origin. In addition to the major histocompatibility complex locus, a genomic segment on 8q11.23 that spans the ST18 gene was also found to be significantly associated with PV. This association was confirmed in the Jewish and Egyptian replication sets but not in the German sample, suggesting that ST18-associated variants may predispose to PV in a population-specific manner. ST18 regulates apoptosis and inflammation, two processes of direct relevance to the pathogenesis of PV. Further supporting the relevance of ST18 to PV, we found this gene to be overexpressed in the skin of PV patients as compared with healthy individuals.

Abstract
BACKGROUND Pemphigus is a worldwide disease and varies in its clinical profile and epidemiology in different regions of the world. The disease is rare and few epidemiological data are available. OBJECTIVE The purpose of this study was to evaluate the epidemiologic, clinical, and therapeutic features of pemphigus in the western region of Turkey. METHODS We retrospectively investigated a total of 87 patients with pemphigus. The parameters including age at diagnosis, sex, diagnostic delay, diagnostic methods, hospitalizations, distribution of skin lesions, duration and dose of therapy, side effects, and duration of follow-up were evaluated. RESULTS The mean age at the onset was 48 years. The average annual incidence of the disease was seven new patients and estimated annual incidence rate was 0.18 per 100,000 inhabitants. The male-to-female ratio was 1/1.64. All patients were treated with systemic corticosteroids. The mean initial dose was 100 mg prednisolone equivalent. Thirty-three (37.9%) patients received azathioprine as adjuvant therapy. The mean time to control the disease activity was 23 days in our study group. Ten patients (11.5%) were in clinical remission without treatment, 41 patients (47.1%) were on low dose steroid (≤ 10 mg daily), and 28 (32.2%) were using > 10 mg/day corticosteroid at the end of the study period. CONCLUSION Pemphigus vulgaris (PV) is the most common clinical subtype in the western part of Turkey. The disease is more frequent in the fifth decade of life and has a female predominance in our region. The patients with both oral mucosa and skin involvement need higher corticosteroid dose, more time to control the disease activity and longer hospitalization time when compared with the patients with oral mucosa involvement alone.

Abstract
FUNDAMENTO: As doenças dermatológicas imunologicamente mediadas compõem diversas patologias que apresentam formas variadas de manifestação no organismo. OBJETIVO: Foi proposição desta pesquisa, estabelecer a prevalência das principais doenças dermatológicas imunologicamente mediadas que apresentam manifestação oral. MÉTODOS: Foram avaliados laudos histopatológicos de 10.292 casos arquivados no Serviço de Anatomia Patológica da Disciplina de Patologia Oral da Universidade Federal do Rio Grande do Norte, no período de 1988 a 2009. Dos casos diagnosticados como algum tipo de doença em estudo, coletaram-se dados clínicos como sexo, idade, raça, sítio anatômico e sintomatologia das doenças. RESULTADOS: Do total de casos registrados, no serviço supracitado, 82 (0,8%) corresponderam a doenças dermato lógicas imunologicamente mediadas com manifestação na cavidade oral. As doenças encontradas neste estudo foram: líquen plano oral, pênfigo vulgar e penfigoide benigno das membranas mucosas, sendo o líquen plano oral a lesão mais prevalente, representando 68,05% dos casos analisados, dos quais 64,3% apresentavam-se em mu lheres, sendo a mucosa jugal o sítio anatômico mais acometido (46,8%). CONCLUSÃO: A ocorrência de doenças dermatológicas imunologicamente mediadas que apresentam manifestação oral ainda é um fato incomum, semelhante ao observado na maioria das regiões mundiais. No entanto, a busca pelo diagnóstico precoce é um requisito essencial para a condução do tratamento dessas doenças, tendo em vista o possível comprometimento sistêmico do organismo nos pacientes.

Abstract
Pemphigus vulgaris (PV) is an autoimmune blistering disorder with a complex etiology involving an interplay of genetic as well as environmental factors, most of which remain unknown. Despite the identification of several human leukocyte antigen (HLA) alleles as risk factors for disease, no other non-HLA genes have clearly been implicated in disease susceptibility. Newer candidate gene and whole-genome approaches are needed to illuminate the full palate of genetic risk elements in PV. Based on this information, genetic-based tools can be expected to provide a scientific rationale for future clinical decision-making by physicians and facilitate an era of personalized medicine.

Abstract
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.

Abstract
BACKGROUND Autoimmune blistering skin diseases are a heterogeneous group of disorders associated with autoantibodies that are directed against desmosomal structural proteins (in pemphigus diseases) or hemidesmosomal ones (in pemphigoid diseases and epidermolysis bullosa acquisita), or else against epidermal/ tissue transglutaminases (in dermatitis herpetiformis). Knowledge of the clinical presentation of these disorders and of the relevant diagnostic procedures is important not just for dermatologists, but also for general practitioners, ophthalmologists, ENT specialists, dentists, gynecologists, and pediatricians. METHODS The literature on the subject was selectively reviewed. There are no existing guidelines available in Germany. RESULTS The recently developed sensitive and specific assays for circulating autoantibodies in these diseases now enable a serological diagnosis in about 90% of cases. The incidence of autoimmune blistering skin diseases in Germany has doubled in the last 10 years, to a current figure of about 25 new cases per million persons per year, because of improved diagnostic techniques as well as the aging of the population. Accurate and specific diagnosis is the prerequisite for reliable prognostication and appropriate treatment. For severe and intractable cases, more effective treatments have recently become available, including immunoadsorption, high-dose intravenous immunoglobulin, the anti-CD20 antibody rituximab, and combinations of the above. CONCLUSION The diagnostic assessment of autoimmune blistering skin diseases can be expected to improve in the near future as new serological testing systems are developed that employ recombinant forms of the target antigens. The treatments currently in use still need to be validated by prospective, controlled trials.

Abstract
BACKGROUND Serum and IgG isolated from patients with the autoimmune blistering disease pemphigus vulgaris (PV) trigger complex intracellular pathways in keratinocytes, including alterations of the cell cycle and metabolism, which ultimately lead to cell-cell detachment (acantholysis). We have shown previously that one of the earliest pathogenic events in PV is the activation of protein kinases, including the PKR-like endoplasmic reticulum (ER) kinase PERK. OBJECTIVES In the present study we investigated in more detail the role of PERK in the pathogenesis of PV. METHODS PERK levels were assessed by Western blotting and in-cell enzyme-linked immunosorbent assay, and PERK expression was silenced by siRNA technology. The effects of PV sera/IgG on keratinocyte cultures were investigated by flow cytometry, MTT and adhesion assays. RESULTS We show that PERK is activated in keratinocytes exposed to PV serum, as demonstrated by an increase in phosphorylated PERK levels and phosphorylation of eIF2α. Decreased expression of PERK by siRNA reduced the effects of PV serum on the cell cycle and keratinocyte viability, two key events in PV pathophysiology. As impairment of metabolic activity in PV is partially due to non-IgG serum factors, we then investigated the activation of PERK in keratinocytes incubated with whole PV serum, purified PV IgG and IgG-depleted PV serum. The data demonstrated that PV sera depleted of IgG, but not PV IgG, triggered PERK phosphorylation and this correlated with a marked reduction of metabolic activity in keratinocytes exposed to IgG-free serum. Knockdown of PERK by siRNA abrogated the changes in the cell cycle and apoptosis induced by IgG-depleted PV serum. Finally, the reduction of metabolic activity observed in keratinocytes exposed to IgG-depleted PV serum was almost absent in PERK-deficient cells. CONCLUSIONS Taken together, the results demonstrate that activation of PERK participates in the reduction of metabolic activity and cell viability seen in PV and that this phenomenon depends on non-IgG factors. PERK activation may represent a novel signalling mechanism linking ER stress and acantholysis in PV.

Abstract
A novel explanation of pemphigus vulgaris (PV) pathogenesis suggests that serum autoantibodies may affect desmoglein 3 (Dsg3)-mediated adhesion by triggering depletion of Dsg3 from desmosomes. Furthermore, abrogation of Dsg3 from the cell seems to depend on anti-Dsg3 pemphigus IgG. In this study we sought to gain more insights into the role of PV IgG recognizing non-conformational epitopes of Dsg3 (anti-Dsg3-L IgG) by semi-quantitative living cell immunofluorescence (LCIF) microscopy, in-cell ELISA and morphometric analysis of acantholysis. Our data demonstrate that PV serum and PV IgG can induce acantholysis and reduce the total amount of Dsg3 in cultured keratinocytes, whereas anti-Dsg3-L IgG fail to do so when administered at concentrations comparable to those present in pathogenic PV sera. However, the Dsg3-depleting activity of such polyclonal anti-Dsg3 IgG was acquired when used at 1 microg/ml. Interestingly, both PV sera and IgG, including anti-Dsg3-L IgG, caused early depletion of surface Dsg3 while slightly affecting the total cell content of Dsg3 until late acantholysis. This raises a possibility that depletion of Dsg3 from cell membrane and reduction of the total cellular levels of Dsg3 represent distinct phenomena in PV acantholysis. Taken together, our data demonstrate that anti-Dsg3 PV IgG against linear epitopes of Dsg3 can induce acantholytic changes of keratinocytes in a dose- and time-dependent manner. Specifically, both morphological and biochemical changes suggestive of acantholysis are seen only at high IgG concentrations. We conclude that anti-Dsg3L IgG play a minor role in experimental PV under physiologic conditions.

Abstract
Pemphigus vulgaris is a rare autoimmune blistering disease, involving the skin and mucous epithelia, which is characterized by flaccid blisters and erosions. It is caused by the presence of autoantibodies directed against desmoglein, a glycoprotein that plays a critical role in cell-cell attachment. Upon a predisposing genetic background, different agents have been shown to act as triggers for the pathogenesis of pemphigus. The most evident association is with drug intake, while the role of diet is often underestimated. The aim of this article is to review the possible role of tannins, a group of phenolic metabolites that are widely distributed in almost all plant foods and beverages, particularly red wine, as a trigger for pemphigus vulgaris.

Abstract
Autoimmune mucocutaneous blistering diseases (AMBD) are a rare group of dermatoses that can be potentially fatal. There are many subtypes and their clinical presentation can vary from being localized to general involvement. It is crucial that a diagnosis be made as early as possible and appropriate treatments are implemented. This article will discuss the diagnosis and available treatments of the major AMBDs. There are very few case-controlled studies regarding the treatments of these diseases. Most of the treatments used for these diseases are based on anecdotal reports. Hence, a synopsis of the conventional treatments and some brief recommendations will also be discussed. A brief discussion regarding "rescue" therapies that have been used for those patients with more recalcitrant cases of AMBD will also be presented.

Abstract
UNLABELLED A focus often exists in dental practice on the maintenance and management of the dentition and the periodontium, however, conditions of the oral mucosa and orofacial pain can cause significant problems for older patients. Oral mucosal conditions are more prevalent in older patients and many orofacial pain disorders, such as burning mouth syndrome and trigeminal neuralgia, are more common in patients over the age of 50 years. Although these conditions may not be routinely managed in general practice, identification of these patients in primary care and appropriate referral will lead to more prompt and effective treatment. CLINICAL RELEVANCE Dental practitioners need to be able to identify what is considered to be within the normal physiological limits of the ageing oral tissue and hence what is abnormal and requires further investigation to facilitate appropriate referral.

Abstract
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.

Abstract
Mucous membrane pemphigoid and pemphigus vulgaris are autoimmune blistering disorders in which many similar drugs and therapeutic strategies are utilized. In general, localized disease can be treated with topical agents. In contrast, patients with more severe and progressive disease usually require a combination of systemic corticosteroids and immunosuppressive medications. Oral corticosteroids, adjuvant immunosuppressive agents, antibiotics such as dapsone and immunomodulatory procedures like intravenous immunoglobulin are the main therapeutic agents used in treating these two disorders. Much of the morbidity and mortality associated with these disorders are related to the sites involved and to the drugs used for therapy. Treatment should be individualized based on severity, extent, and rate of progression of disease, comorbidities, and age of the patient. Serum levels of specific autoantibodies and indirect immunofluorescence titers, in certain cases, can be used to monitor response to therapy.

Abstract
Esophagitis dissecans superficialis (EDS) is a rare and severe endoscopic finding characterized by sloughing of large fragments of esophageal mucosal lining. Although EDS has been reported in association with serious illnesses and certain medications, the pathophysiological association of autoimmune bullous dermatoses with EDS has gained remarkable attention. Among these dermatoses, pemphigus vulgaris and pemphigoid frequently present with various types of esophageal involvement including EDS. We review the pathophysiology and clinical features of this involvement with the presentation of our experiences. The importance of endoscopic evaluation of this entity is discussed.

Abstract
Pemphigus and pemphigoid are different types of autoimmune bullous disease and can occur in the same patient. We report a female patient with this condition. At first, we diagnosed her with bullous pemphigoid, and we treated her with tetracycline, niacinamide and a topical steroid. Tense bullas disappeared shortly after that, but crusted erythemas mainly on her head and trunk persisted. We examined BP180 and desmoglein 1 enzyme-linked immunosorbent assays, and also histological features, which showed coexistence of bullous pemphigoid and pemphigus foliaceus concurrently. Therefore, we tried prednisolone, which could control both conditions. This case showed that tetracycline and niacinamide could control bullous pemphigoid, but could not control pemphigus foliaceus, and that prednisolone was effective for both conditions.

Abstract
Treatment of autoimmune bullous skin diseases can often be challenging and primarily consists of systemic corticosteroids and a variety of immunosuppressants. Current treatment strategies are effective in most cases but hampered by the side effects of long-term immunosuppressive treatment. Intravenous immunoglobulin (IVIG) is one potential promising therapy for patients with autoimmune bullous skin diseases, and evidence of its effectiveness and safety is increasing. A number of autoimmune bullous skin diseases have been identified in which IVIG treatment may be beneficial. However, experience with IVIG in patients with autoimmune skin blistering disease is limited, where it is recommended for patients not responding to conventional therapy. The mode of action of IVIG in autoimmune diseases, including bullous diseases is far from being completely understood. We here summarize the clinical evidence supporting the notion, that IVIG is a promising therapeutic agent for the treatment of patients with autoimmune bullous skin disease. In addition, we review the proposed modes of action. In the future, randomized controlled trials are necessary to better determine the efficacy and adverse effects of IVIG in the treatment of autoimmune bullous skin diseases. In addition, insights into IVIG's mode of action might enable us to develop novel therapeutics to overcome the current shortage of IVIG.

Abstract
Endemic pemphigus foliaceus, known as Fogo Selvagem (FS) in Brazil, is a disease characterized by subcorneal blisters and IgG4 anti-dermoglein 1 (Dsg1) autoantibodies. Epidemiological studies of FS strongly an environmental etiology. A 15-year surveillance of the Limao Verde Amerindian reservation in Brazil has uncovered information on the transition of the autoimmune response from the pre-clinical stage to disease state. This incubation time may evolve over several years. The serological markers of the pre-clinical state of FS are IgM anti-Dsg1, IgE and non-IgG4 autoantibodies against Dsg1. The disease stage of FS is characterized by the rise of pathogenic IgG4 anti-Dsg1 autoantibodies. In this review, the authors reviewed the literature on the relevance of the humoral autoimmune response of FS as well as the possible environmental triggers of anti-Dsg1 autoantibody formation. Based on epidemiological observations, the authors hypothesize that the pathogenic IgG4 response in FS may be triggered by hematophagous insect bites.

Abstract
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.
