Abstract
BACKGROUND The incidence of malignant tumors has increased in patients with non-paraneoplastic pemphigus, although there has been no systematic analysis of global epidemiology. OBJECTIVE To explore the epidemiology of various types of non-paraneoplastic pemphigus associated with malignant tumors. METHODS Five databases from establishment through October 20, 2023, were searched. STATA SE 17 was used for the data analysis. Subgroup, meta-regression, and sensitivity analyses were used to evaluate the heterogeneity of pooled studies. RESULTS A total of 6679 participants were included in our meta-analysis from 16 studies. The aggregated prevalence of tumors in patients diagnosed with pemphigus was 8%. The prevalence was 7% in patients with pemphigus vulgaris, 10% in those with pemphigus foliaceus, and 12% in individuals diagnosed with other types of pemphigus. The prevalence was 8% in Asia, 11% in Europe, and 8% in North America. From a country-specific perspective, patients with pemphigus from Israel, Greece, and Germany exhibited a higher prevalence of tumors at 11%. Furthermore, when categorized by the duration of the study period, the highest prevalence was observed in studies spanning 10 to 20 years, at 11%. CONCLUSION These findings demonstrate the incidence and prevalence of malignant tumors in patients with non-paraneoplastic pemphigus, which may achieve early detection and intervention, and then reduce mortality rates.

Abstract
BACKGROUND Systematic reviews of Randomized Controlled Trials (RCTs) are considered high-level evidence to support a decision on therapeutic interventions, and their methodological quality is essential to provide reliable and applicable results. OBJECTIVE This meta-epidemiological study aimed to map and critically appraise systematic reviews assessing treatments for vesiculobullous skin diseases. METHODS We conducted a comprehensive search strategy on MEDLINE (via Pubmed) in December 2022 without restrictions to find systematic reviews evaluating pharmacological interventions for vesiculobullous skin diseases. The methodological quality was assessed using the AMSTAR-2 tool, and additional information was extracted. We identified nine systematic reviews published between 2002 and 2021, seven assessing pemphigus. RESULTS According to the AMSTAR-2 tool, 55.6% were classified as critically low quality, 22.2% as moderate quality, 11.1% as low and 11.1% as high quality. No review assessed the certainty of the evidence (GRADE); 86% of pemphigus reviews had at least two overlapping RCTs. There were some limitations regarding methodological flaws and the AMSTAR-2 tool use CONCLUSIONS: These findings reveal a frail methodological quality of systematic reviews about vesiculobullous diseases treatment that may impact the results. Therefore, methodological rigor is mandatory for future systematic reviews to avoid duplication of effort and increase the certainty of the evidence supporting decision-making.

Abstract
INTRODUCTION Pemphigus is a therapeutically challenging disease with high morbidity and economic burden. First-line prescription of rituximab remains limited in Tunisia due to its high cost. Systemic steroids remain the standard of care but are associated with a major risk of morbidities and higher treatment costs. AIM To assess the direct medical costs of pemphigus in Tunisia. METHODS Retrospective estimation of direct medical costs during the 18 months following the diagnosis using the "bottom-up approach" in the Dermatology Department of Hedi Chaker Hospital, Sfax, Tunisia. RESULTS Total medical costs were estimated at 38745.7 €, with an average cost of 1 210 € per patient and per year: paraclinical investigations (46%), medical treatment (30%), hospitalization (21%) and outpatient visits (3%). The average cost was the highest in the age group of 15-24 years (1553 €). Treatment costs related to corticosteroid-induced morbidity were estimated at 1208 €. CONCLUSIONS The management of pemphigus in Tunisia needs to be adapted to take into account the health economic analysis in order to reduce overall disease costs and the burden of steroid-induced morbidities.

Abstract
PROBLEM Pemphigus vulgaris may worsen during pregnancy, leading to both maternal and fetal complications. The relationship between pemphigus vulgaris and pregnancy remains unclear, and the outcomes and treatments of pemphigus vulgaris during pregnancy have not been extensively discussed. METHOD OF STUDY This article systematically reviews the literature, focusing on the relationship between pemphigus vulgaris and pregnancy. We conducted comprehensive searches in PubMed, Embase, Cochrane Library, and Web of Science databases, identifying 42 studies reporting the disease course, pregnancy outcomes, and management of both pregnancy and pemphigus vulgaris. RESULTS A total of 57 cases were included in the analysis, categorized into three distinct forms: pemphigus vulgaris onset before pregnancy (n = 33), onset during pregnancy (n = 20), and onset during the postpartum period (n = 4). Fifty four cases reported treatment strategies, among them, 44 cases (81.5%) initially received systemic corticosteroid therapy during pregnancy. Out of these cases, 7 (15.9%) did not achieve successful remission and required alternative treatment approaches. In terms of pregnancy outcomes, 23 out of 62 neonates (37.1%) exhibited skin lesions or tested positive for anti-dsg IgG in their serum, while 16 neonates (25.8%) experienced other complications. CONCLUSIONS These findings highlight the importance of effectively managing pemphigus vulgaris during pregnancy to ensure optimal outcomes.

Abstract
BACKGROUND Pemphigus and pemphigoid are rare autoimmune skin disorders caused by autoantibodies against structural proteins and characterized by blistering of the skin and/or mucous membranes. Associations have been noted between skin diseases and Alzheimer's dementia (AD). Dementia is a neurological disorder of progressive cognitive impairment with increasing incidence among older adults. This study aimed to assess the potential associations between pemphigus, pemphigoid and AD in a large, nationally representative US cohort. METHODS All data of hospitalized patients aged 60 years or older were extracted from the US Nationwide Inpatient Sample (NIS) database 2016-2018. Patients with a history of head trauma, diagnosis of vascular dementia, history of cerebrovascular disease, or malformation of cerebral vessels were excluded. The study population was divided into those with and without pemphigus (cohort 1) and with and without pemphigoid (cohort 2). RESULTS Pemphigus was independently associated with a 69% increased risk of AD. Adults ≥80 years old with pemphigus were 72% more likely to develop AD than adults without pemphigus. Women with pemphigus were 78% more likely to develop AD than women without pemphigus. On the other hand, pemphigoid was independently associated with a 39% increased risk for AD and subjects ≥80 years with pemphigoid were 40% more likely to have AD than those without pemphigoid. Females with pemphigoid were 63% more likely to have AD than those without pemphigoid. Moreover, Hispanic older adults with pemphigus were 3-times more likely to have AD than those without pemphigoid. CONCLUSIONS Pemphigus and pemphigoid were both independently associated with AD in older adults, especially among females and octogenarians. Further studies addressing the etiology and mechanisms underlying these associations are highly warranted.

Abstract
Bullous pemphigoid has a high incidence among dialysis patients. However, whether or not chronic dialysis is an independent risk factor of bullous pemphigoid remains unclear. We aimed to investigate the effect of chronic dialysis on the development of bullous pemphigoid and pemphigus. We performed a retrospective cohort study using records from Taiwan's National Health Insurance Research Database between 2008 and 2019. We identified a dialysis cohort that included patients on chronic hemodialysis and peritoneal dialysis, and the hazard ratios (HRs) for bullous pemphigoid and pemphigus were compared with those of a sex-, age-, and index-matched cohort, then the results were adjusted for various confounding factors. Among 93 538 patients on chronic dialysis and 93 538 patients in the control group, 287 and 139 developed incident bullous pemphigoid, and 45 and 35 developed incident pemphigus after a median follow-up of 3.7 and 5.6 years, respectively. The incidence rates of bullous pemphigoid in the dialysis patients and the control group were 74.2 and 25.2 per 100 000 person-years, respectively (difference between groups, P < 0.0001). The incidence rates of pemphigus in the dialysis patients and the control group were 11.6 and 6.3 per 100 000 person-years, respectively (difference between groups, P < 0.01). Cox proportional hazard adjustment showed the HR for bullous pemphigoid in dialysis patients was 2.12 (95% confidence interval [CI] 1.64-2.74, P < 0.0001) compared with the control group. Dialysis patients aged <75 years had an even higher risk of bullous pemphigoid development (5- to 8-fold) than the control group. The adjusted HR for pemphigus was not elevated in dialysis patients (adjusted HR 1.52, 95% CI 0.87-2.67, P = 0.14). Chronic dialysis is an independent risk factor for developing bullous pemphigoid, but not a risk factor for pemphigus. Physicians should be aware of the predisposition of chronic dialysis patients to bullous pemphigoid.

Abstract
Introduction Autoimmune bullous diseases (AIBDs) are a group of rare cutaneous disorders affecting cornified skin and mucous membranes. They are characterized by tense or flaccid blistering and erosions due to autoantibodies against desmosomal and hemidesmosomal structural proteins of the skin. This group of disorders can be divided into those of pemphigoid and those of pemphigus diseases. If left untreated, these autoimmune diseases can cause serious or even life-threatening complications such as loss of fluid, superinfections or impaired food intake. Due to modern standardized serological assays, the diagnosis of AIBDs can usually be confirmed in combination with their clinical appearance. Whereas for a long time corticosteroids were the major players in the treatment of these diseases, with the approval of rituximab and other immunosuppressive agents, the therapy has increasingly improved. Methods In this study, we aimed to investigate epidemiologic and clinical features as well as diagnostics and therapy of bullous autoimmune diseases in Middle Franconia, a governorate within the German federal state of Bavaria. Patients diagnosed or treated because of a AIBDs between 01.04.2013 and 31.03.2019 at the dermatological department of the university hospital Erlangen were included in this retrospective study (n = 242). Patients were either diagnosed for the first time (n=176) or the diagnosis has been confirmed (n=66) at the department. The respective incidence was calculated among the 176 subjects who had been diagnosed at the center in this period. Data was taken from patient records and analyzed with Microsoft® Excel. The evaluation included the diagnoses of pemphigus vulgaris (PV), pemphigus foliaceus (PF), bullous pemphigoid (BP), mucous membrane pemphigoid (MMP), linear IgA dermatosis (LAD), epidermolysis bullosa acquisita (EBA), and dermatitis herpetiformis (DH). Results This study shows that the incidence of each AIBDs in Middle Franconia is low and comparable (PV, PF, LAD, EBA) or lower (BP, MMP, DH) than in other studies and regions. BP is the most common newly diagnosed AIBD in Middle Franconia. Discussion Due to the chronic and sometimes severe course of AIBDs, repeated in-house treatments are often necessary. To date, mainly topically and systemically applied corticosteroids in combination with immunomodulators are used as first-line therapy.

Abstract
Background Bullous pemphigoid (BP) and pemphigus vulgaris (PV) share similar pathophysiology with venous thromboembolism (VTE) involving platelet activation, immune dysregulation, and systemic inflammation. Nevertheless, their associations have not been well established. Methods and Results To examine the risk of incident VTE among patients with BP or PV, we performed a nationwide cohort study using Taiwan's National Health Insurance Research Database and enrolled 12 162 adults with BP or PV and 12 162 controls. A Cox regression model considering stabilized inverse probability weighting was used to calculate the hazard ratios (HRs) for incident VTE associated with BP or PV. To consolidate the findings, a meta-analysis that incorporated results from the present cohort study with previous literature was also conducted. Compared with controls, patients with BP or PV had an increased risk for incident VTE (HR, 1.87 [95% CI, 1.55-2.26]; P<0.001). The incidence of VTE was 6.47 and 2.20 per 1000 person-years in the BP and PV cohorts, respectively. The risk for incident VTE significantly increased among patients with BP (HR, 1.85 [95% CI, 1.52-2.24]; P<0.001) and PV (HR, 1.99 [95% CI, 1.02-3.91]; P=0.04). In the meta-analysis of 8 studies including ours, BP and PV were associated with an increased risk for incident VTE (pooled relative risk, 2.17 [95% CI, 1.82-2.62]; P<0.001). Conclusions BP and PV are associated with an increased risk for VTE. Preventive approaches and cardiovascular evaluation should be considered particularly for patients with BP or PV with concomitant risk factors such as hospitalization or immobilization.

Abstract
Autoimmune blistering diseases such as bullous pemphigoid (BP) and pemphigus vulgaris (PV) are complex, multifactorial, and polygenic diseases, whose exact pathogenesis is difficult to pinpoint. Research aimed at elucidating the associated epidemiologic risk factors of these two diseases has been hampered by their rare disease status. Further, a lack of centralization and standardization of available data makes the practical application of this information challenging. In order to collate and clarify the available literature we comprehensively reviewed 61 PV articles from 37 different countries and 35 BP articles from 16 different countries addressing a range of disease relevant clinical parameters including age of onset, sex, incidence, prevalence, and HLA allele association. The reported incidence of PV ranged from 0.098 to 5 patients per 100,000 people, while BP ranged from 0.21 to 7.63 patients per 100,000. Prevalence of PV ranged from 0.38 to 30 per 100,000 people and BP ranged from 1.46 to 47.99 per 100,000. The mean age of onset in patients ranged from 36.5 to 71 years for PV and 64 to 82.6 years for BP. Female-to-male ratios ranged from 0.46 to 4.4 in PV and 1.01 to 5.1 in BP. Our analysis provides support for the reported linkage disequilibrium of HLA DRB1*0402 (an allele previously shown to be associated with PV) and DQB1*0302 alleles in Europe, North America, and South America. Our data also highlight that HLA DQB1*0503 (also known to be associated with PV) appears in linkage disequilibrium with DRB1*1404 and DRB1*1401, mainly in Europe, the Middle East, and Asian countries. The HLA DRB1*0804 allele was only associated with PV in patients of Brazilian and Egyptian descent. Only two HLA alleles were reported as associated with BP more than twice in our review, DQB1*0301 and DQA1*0505. Collectively, our findings provide detailed insights into the variation of disease parameters relevant to PV and BP that can be expected to inform future work aimed at unraveling the complex pathogenesis of these conditions across the globe.

Abstract
Autoimmune bullous skin diseases (AIBDs), such as bullous pemphigoid (BP) and pemphigus, are characterized and caused by autoantibodies targeting structural proteins. In BP, clinical experience and recent systematic evaluation identified pruritus to be common and an important cause of impaired quality of life. Furthermore, chronic pruritus may be the sole clinical symptom of BP. In pemphigus, a retrospective study recently documented a high prevalence of pruritus. The temporal relation between pruritus and BP/pemphigus are, however, unknown. Likewise, the presence of pruritus in AIBDs other than BP and pemphigus is unknown. To address this, we performed propensity-matched retrospective cohort studies using TriNetX, providing real-world patient data to (i) assess the risk to develop AIBDs following the diagnosis of pruritus and (ii) vice versa. We assessed this in eight AIBDs: BP, mucous membrane pemphigoid (MMP), epidermolysis bullosa acquisita, dermatitis herpetiformis, lichen planus pemphigoides (LPP), pemphigus vulgaris, pemphigus foliaceous, and paraneoplastic pemphigus (PNP). For all AIBDs, pruritus was associated with an increased risk for the subsequent diagnosis of each of the eight investigated AIBDs in 1,717,744 cases (pruritus) compared with 1,717,744 controls. The observed hazard ratios ranged from 4.2 (CI 3.2–5.5; p < 0.0001) in MMP to 28.7 (CI 3.9–211.3; p < 0.0001) in LPP. Results were confirmed in two subgroup analyses. When restricting the observation time to 6 months after pruritus onset, most HRs noticeably increased, e.g., from 6.9 (CI 6.2–7.9; p < 0.0001) to 23.3 (CI 17.0–31.8; p < 0.0001) in BP. Moreover, pruritus frequently developed following the diagnosis of any of the eight AIBDs, except for PNP. Thus, all AIBDs should be considered as differential diagnosis in patients with chronic pruritus.

Abstract
A seven-year retrospective study was held at the Department of Dermatology, Lady Reading Hospital, Peshawar, between 2013 to 2020 to determine the demography and clinical features of pemphigus. Among 148 patients included in this study 88 (58%) were females and 60 (40%) were males with a female to male ratio of 1.46:1. Average age at onset of the disease was 38±12 years (range 14-75 years). On the basis of Autoimmune Bullous Skin Disorder Score (ABSIS), 14 (9.3%) patients had mild disease, 58 (38.7%) had moderate disease, and 76 (50.7%) patients had severe disease. In total, 144 (96%) patients had pemphigus vulgaris, 3 (2%) patients had pemphigus foliaceous and 1 (0.7%) patient had paraneoplastic pemphigus. Severe pemphigus was more frequently associated with multiple relapses (p=0.00). This study shows poor prognostic factors like severe pemphigus vulgaris associated with multiple relapses. Five years of follow-up shows that complete remission on minimal therapy was achieved more in patients who received Rituximab.

Abstract
Previous studies have found conflicting results about the association of autoimmune blistering disease (AIBD) with cardiovascular disease (CVD) risk. The objective of the study was to systematically review the relationship of AIBD, including pemphigus vulgaris (PV), and its treatment with CVD and CVD risk factors. MEDLINE, EMBASE, Cochrane, LILACS, SCOPUS, and Web of Science were searched. We included all studies of CVD and CVD risk factors in AIBD patients. Two reviewers performed title and/or abstract review and data extraction. Pooled random-effects meta-analysis was performed. Forty papers met inclusion criteria. AIBD was associated with higher odds of diabetes (DM) (odds ratio [95% confidence interval]: 1.809 [1.258-2.601]), hypertension (HTN) (1.393 [1.088-1.784]), dyslipidemia (2.177 [1.163-4.073]) and heart failure (1.919 [1.603-2.298]), but was not associated with obesity, stroke, angina, heart attack, or arrhythmia. The pooled random-effects prevalence for treatment-related adverse events (AEs) in AIBD was 13.7% for DM, 10.7% for HTN, and 17.1% for CVD. Sensitivity analysis of high-quality studies revealed similar results. AIBD patients have increased CVD risk factors and heart failure. Systemic corticosteroid treatment results in CVD-related AEs in AIBD. Increased CVD screening and prevention strategies are warranted in AIBD.

Abstract
Importance The association of different therapeutic approaches with long-term cardiovascular and metabolic outcomes in patients with pemphigus remains to be precisely evaluated. Objective To assess the risk of long-term cardiovascular and metabolic outcomes and all-cause mortality in patients with pemphigus managed by rituximab compared with those receiving treatment with first-line corticosteroid-sparing agents (azathioprine and mycophenolate mofetil [MMF]). Design, Setting, and Participants A global population-based retrospective cohort study compared 961 patients with pemphigus that was managed with rituximab with those treated with azathioprine or MMF (n = 961) regarding the risk of several cardiovascular and metabolic outcomes. Propensity score matching was performed to optimize comparability. Patients were enrolled from the Global Collaborative Network of TriNetX platform. Main Outcomes and Measures Risk of myocardial infarction, stroke, peripheral vascular disease, pulmonary embolism, hypertension, hyperlipidemia, type 2 diabetes, obesity, osteoporosis, and avascular bone necrosis. Results Of 1602 participants, 855 (53.4%) were women and 747 (46.6%) were men; the mean (SD) age was 54.8 (16.6) years for those treated with rituximab and 54.4 (18.2) years for those treated with azathioprine or MMF. Compared with those treated by azathioprine/MMF, patients treated with rituximab experienced a lower risk of myocardial infarction (relative risk [RR], 0.45; 95% CI, 0.24-0.86; P = .01), stroke (RR, 0.42; 95% CI, 0.26-0.69; P < .001), peripheral vascular disease (RR, 0.47; 95% CI, 0.28-0.79; P = .003), hypertension (RR, 0.48; 95% CI, 0.38-0.63; P < .001), hyperlipidemia (RR, 0.45; 95% CI, 0.32-0.64; P < .001), type 2 diabetes (RR, 0.63; 95% CI, 0.51-0.77; P < .001), obesity (RR, 0.49; 95% CI, 0.34-0.72; P < .001), and osteoporosis (RR, 0.46; 95% CI, 0.30-0.71; P < .001). The all-cause mortality was comparable between patients in both groups (hazard ratio, 0.94; 95% CI, 0.62-1.43; log-rank P = .77). Conclusions and Relevance The results of this cohort study suggest that rituximab was associated with protection against long-term cardiovascular and metabolic outcomes compared with conventional immunosuppressants. This agent might be particularly preferred in individuals with preexisting cardiovascular and metabolic risk factors.

Abstract
Pemphigus vulgaris (PV) is an autoimmune bullous dermatosis with uneven geographic distribution and higher incidence in certain populations. In previous studies, a relatively high incidence of PV was reported in Bulgaria (0.47/100,000/year) comparable to that in other countries. The genetic background was considered responsible for the disease susceptibility, and multiple reports have proven PV to be an HLA-associated condition. The aim of our study was to analyze the role of genetic factors in the development of PV in Bulgaria. HLA genotyping was performed in 56 PV patients, ethnic Bulgarians whose diagnosis was confirmed based on clinical, histological, and immunofluorescent findings. The control group consisted of 204 healthy individuals from the Bulgarian population without evidence for HLA-associated autoimmune diseases. HLA-A,-B,-DRB1,-DQB1 analysis was performed by PCR-SSP. Our results revealed predisposing associations with DRB1*14, DRB1*04:02, and B*38, B*55, while allele DRB1*03:01 and the corresponding haplotypes were significantly decreased in the PV patients. The predisposing role of these alleles has been observed in other populations. All reported predisposing DRB1 alleles have the same amino acids at key positions of the beta chain of the HLA molecules, 26 (Phe), 67 (Leu or Ileu), 70 and 71 (hydrophobic AA: Gln, Arg, Asp, or Glu), and 86 (Val), which is important for the selective presentation of desmoglein 3 peptides. Additionally, specific alleles HLA-A*01 and DRB1*11 were identified with decreased frequencies in the patients’ group, the last one being a common protective allele for autoimmune diseases in the Bulgarian population. The elucidation of the role of genetic factors for the development of pemphigus will help explain its higher incidence and clinical variability in certain populations.

Abstract
IntroductionPemphigus encompasses a group of muco-cutaneous autoimmune bullous diseases characterized by the loss of adhesion between keratinocytes. The disease is associated with increased morbidity and mortality.Materials and MethodsWe characterized clinical patterns, survival, comorbidities, and drug prescriptions in patients with pemphigus referred to the Section of Dermatology of the University of Florence from January 2010 to December 2021.ResultsA total of 149 patients were identified (female/male sex ratio = 2.0). Median age at diagnosis was 57.7 ± 17.2 years; 108 patients were diagnosed with pemphigus vulgaris (PV) (72.5%) and 35 (23.5%) with pemphigus foliaceus (PF). Paraneoplastic pemphigus (PNP) and IgA-pemphigus accounted for three patients each. The overall survival rate was 86.9%. Accordingly, 14 (9%) patients died during the study period. The average age at death was 77.8 ± 9.3. Age at diagnosis was a risk factor for death in patients with pemphigus. Average concentration of Dsg3-IgG and Dsg1-IgG was 85.6 ± 68.8 and 75.9 ± 68.4, respectively. The most serious comorbid diseases included cerebro- and cardiovascular accidents and malignancies. Regarding the treatment regimen, we found a substantially stable use of systemic steroids in the 2010–2018 period; the prevalence of use of mycophenolic acid increased, whereas that of azathioprine decreased. The use of rituximab showed the highest increase in the 2013–2018 period. Proton-pump inhibitors and antibiotics were the most frequently prescribed non-immunomodulating drugs.ConclusionsIn this large series of the patients, patients with pemphigus showed a high incidence of serious comorbid diseases, highlighting the importance of a multidisciplinary approach for a proper management of the patients. Rituximab was the immunomodulating drug showing the highest increase in use over time, reflecting the growing evidence of its efficacy as a first-line treatment in pemphigus.

Abstract
In the endemic variants of pemphigus foliaceus (PF), in Brazil and Tunisia, patients generate pathogenic IgG4 anti-desmoglein 1 autoantibodies. Additionally, these patients possess antibodies against salivary proteins from sand flies that react with Dsg1, which may lead to skin disease in susceptible individuals living in endemic areas. This minireview focuses on recent studies highlighting the possible role of salivary proteins from Lutzomyia longipalpis (L. longipalpis) in EPF from Brazil and Phlebotomus papatasi (P. papatasi) in EPF from Tunisia. We will briefly discuss the potential mechanisms of molecular mimicry and epitope spreading in the initiation and development of endemic PF (EPF) in Brazil and Tunisia.

Abstract
Background/aim Autoimmune bullous diseases, if left untreated, are life-threatening conditions affecting primarily skin and mucous membranes. These blistering disorders are characterized by epidermal or subepidermal detachment. Autoimmunity plays a key role in pathogenesis; therefore, immunosuppressive agents are the treatment of choice. The aim of this study is to document relative frequencies of different autoimmune bullous diseases, patient characteristics, treatment options, and side effects in patients presenting to our bullous skin disease center at İstanbul University, Cerrahpaşa, Cerrahpaşa Medical Faculty. Materials and methods Medical files were examined retrospectively for all patients with autoimmune bullous diseases who were followed up between 2003 and 2019 at the Bullous Skin Disease Center at İstanbul University, Cerrahpaşa. Results A total of 346 patient files were examined. Pemphigus vulgaris was the most frequent autoimmune bullous disease, followed by bullous pemphigoid and pemphigus foliaceus, according to our study. There is a general female predominancy for all autoimmune bullous diseases. The most commonly preferred treatment options were high-dose daily corticosteroids. Conclusion This retrospective study summarizes the patient characteristics, comorbidities, treatment choices, and side effects during 16 years of clinical practice.

Abstract
Epitope spreading is an important mechanism for the development of autoantibodies (autoAbs) in autoimmune diseases. The study of epitope spreading in human autoimmune diseases is limited due to the major challenge of identifying the initial/primary target epitopes on autoantigens in autoimmune diseases. We have been studying the development of autoAbs in an endemic human autoimmune disease, Brazilian pemphigus foliaceus (or Fogo Selvagem (FS)). Our previous findings demonstrated that patients before (i.e. preclinical) and at the onset of FS have antibody (Ab) responses against other keratinocyte adhesion molecules in addition to the main target autoantigen of FS, desmoglein 1 (Dsg1), and anti-Dsg1 monoclonal Abs (mAbs) cross-reacted with an environmental antigen LJM11, a sand fly saliva protein. Since sand fly is prevalent in FS endemic regions, individuals in these regions could develop Abs against LJM11. The anti-LJM11 Abs could recognize different epitopes on LJM11, including an epitope that shares the structure similarity with an epitope on Dsg1 autoantigen. Thus, Ab response against this epitope on LJM11 could be the initial autoAb response detected in individuals in FS endemic regions, including those who eventually developed FS. Accordingly, this LJM11 and Dsg1 cross-reactive epitope on Dsg1 could be the primary target of the autoimmune response in FS. This investigation aimed to determine whether the autoAb responses against keratinocyte adhesion molecules are linked and originate from the immune response to LJM11. The anti-Dsg1 mAbs from preclinical FS and FS individuals were employed to determine their specificity or cross-reactivity to LJM11 and keratinocyte adhesion molecules. The cross-reactive epitopes on autoantigens were mapped. Our results indicate that all tested mAbs cross-reacted with LJM11 and keratinocyte adhesion molecules, and we identified an epitope on these keratinocyte adhesion molecules which is mimicked by LJM11. Thus, the cross-reactivity could be the mechanism by which the immune response against an environmental antigen triggers the initial autoAb responses. Epitope spreading leads to the pathogenic autoAb development and ensuing FS among genetically susceptible individuals.

Abstract
Data regarding the association between pemphigus and rheumatoid arthritis (RA) is inconclusive and yet to be firmly established. In the current study, we aimed to evaluate the risk of developing RA during the course of pemphigus. A large-scale population-based longitudinal cohort study was conducted to evaluate the hazard ratio (HR) of RA among 1985 patients with pemphigus relative to 9874 age-, sex-, and ethnicity-matched control subjects. A multivariate Cox regression model was utilized. The incidence of RA was 1.07 (95% CI, 0.62-1.72) and 0.36 (95% CI, 0.24-0.52) per 1000 person-years among patients with pemphigus and controls, respectively. The lifetime prevalence of RA was 2.3% (95% CI, 1.7-3.1%) among cases and 1.8% (95% CI, 1.5-2.0%) among controls. Patients with pemphigus were more than twice as likely to develop RA as compared to control subjects (adjusted HR, 2.54; 95% confidence interval [CI], 1.31-4.92). The increased risk was robust to a sensitivity analysis that included only cases managed by pemphigus-related systemic medications (adjusted HR, 2.56; 95% CI, 1.30-5.05). In conclusion, pemphigus is associated with an increased risk of RA. Physicians treating patients with pemphigus should be aware of this possible association. Further research is required to better understand the mechanism underlying this association.

Abstract
Although pemphigus has recently been linked to psoriasis, the risk of emergence of pemphigus during the course of psoriasis is yet to be delineated. The aim of this study was to evaluate the risk of developing pemphigus during the course of psoriasis. A large-scale population-based longitudinal retrospective cohort study was performed to assess the hazard ratio (HR) of pemphigus among 68,836 patients with psoriasis relative to 68,836 age-, sex-, and ethnicity-matched controls. The incidence of pemphigus was 0.14 (95% confidence interval (95% CI) 0.10–0.19) and 0.04 (95% CI 0.02–0.07) per 1,000 person-years among psoriatic patients and controls, respectively. Patients with psoriasis were more than 3 times as likely to develop pemphigus (HR 3.25; 95% CI 1.70–6.21). The increased risk remained statistically significant following adjustment for several confounders (adjusted HR 3.19; 95% CI 1.67–6.11). To conclude, psoriasis is associated with an elevated risk of pemphigus. Further research is needed to explore the immunoserological profile of patients with a dual diagnosis.

Abstract
BACKGROUND Data on trends in epidemiological characteristics and economic burden of pemphigus are scarce. OBJECTIVE To describe national trends in pemphigus' incidence, mortality, hospitalizations, and expenditures between 2003 and 2015 in Taiwan. METHODS This nationwide study used the Taiwan National Health Insurance Research Database to identify pemphigus patients from 2003 to 2015. Annual incidence, prevalence, healthcare utilization, and expenditure trends were calculated and analyzed. RESULTS Pemphigus' incidence increased significantly from 3.19 to 4.70 per million person-years in 2003-2010 but fluctuated in 2011-2015. Pemphigus patients had higher mortality and care costs. Medical utilization and expenditure declined for pemphigus inpatients and outpatients. Systemic corticosteroid use decreased, but mortality remained stable. CONCLUSION The health expense reduction for pemphigus was mainly attributed to decreased utilization, length of stay, and inpatient costs. The persistently elevated mortality rate highlights an unmet need in pemphigus therapy.

Abstract
INTRODUCTION Pemphigus is a chronic, relapsing immunobullous disease. There is limited data on the clinical course and prognostic factors of pemphigus in Asian patients. MATERIALS AND METHODS We conducted a retrospective cohort study of all newly diagnosed pemphigus vulgaris (PV) and pemphigus foliaceus (PF) patients seen at the National Skin Centre from 1 January 2004 to 31 December 2009. Demographic and clinical data on comorbidities, treatment and remission were recorded. Mortality information was obtained from the National Registry of Diseases. Prognostic endpoint was overall remission at last visit. RESULTS Sixty- one patients (36 PV and 25 PF) were recruited. Among PV patients, higher initial prednisolone dose (P = 0.017) and the use of azathioprine (P = 0.028) were significantly associated with overall remission at last visit. However, higher desmoglein 1 antibody titres at diagnosis (P = 0.024) and the use of dapsone (P = 0.008) were negatively associated with overall remission at last visit. Among PF patients, only higher desmoglein 1 antibody titre at diagnosis (P = 0.041) was found to be associated with lower overall remission at last visit. There was no mortality during the 3-year follow-up period in both PV and PF. CONCLUSION Higher initial prednisolone dose and the use of azathioprine in PV desmoglein 1 antibody titre at diagnosis in PV and PF might be prognostic markers for achieving remission. Use of dapsone was associated with lower overall remission in PV, but this might be confounded because dapsone was used as an adjuvant therapy in recalcitrant cases. Owing to study methodology and limitations, further evaluation is needed for better prognostication of pemphigus.

Abstract
BACKGROUND Red blood cell distribution width (RDW) has recently emerged as an inflammatory marker in several inflammatory diseases but has not been investigated in patients with pemphigus. OBJECTIVE We aimed to examine RDW percentage in patients with pemphigus relative to control subjects and to assess the association between this biomarker and the morphological characteristics of the disease. METHODS This case-control study included 183 pemphigus patients and 915 age- and sex-matched control subjects. RDW, hemoglobin, and mean corpuscular volume (MCV) were measured for all study participants. RESULTS The RDW was significantly higher in patients with pemphigus than in controls (13.7±1.3 vs. 13.4±1.1%, respectively; P=0.001). A significant association between RDW and pemphigus was demonstrated in multivariate analysis (odds ratio, 1.22; 95% confidence interval, 1.01-1.46; P=0.036). The RDW was higher in patients with pemphigus vulgaris (PV) than in pemphigus foliaceus (PF; P=0.043), and in those with mucocutaneous PV relative to those with mucosal only and cutaneous only PV. The RDW increased significantly following treatment (P<0.001). CONCLUSION Pemphigus patients demonstrated elevated RDW as compared with healthy controls. RDW may be a feasible biomarker in patients with pemphigus. Although it clearly does not replace any of the accepted diagnostic immunopathological criteria, increased RDW may be more suggestive of PV than PF, and of mucocutaneous rather than cutaneous PV. The remarkable increase following treatment may be ascribed to the corticosteroid-induced erythropoiesis.

Abstract
Patients with pemphigus and bullous pemphigoid (BP) have potential risk factors for osteoporosis and/or fractures. To determine whether pemphigus and BP are associated with osteoporosis and fractures in the US, a cross-sectional study of 198,102,435 adults was performed, including 4506 with pemphigus and 8864 with BP from the 2006-2012 National Emergency Department Sample, a 20% sample of emergency care visits throughout the US. Pemphigus was associated with higher odds (multivariate logistic regression; adjusted odds ratio [95% confidence intervals]) of osteopenia (2.20 [1.59-3.05]), osteoporosis (2.54 [2.16-2.98]), osteomalacia (29.70 [4.05-217.83]), and pathological fractures (2.04 [1.42-2.91]). BP was associated with osteoporosis (1.55 [1.39-1.73]) and pathological fractures (1.52 [1.22-1.88]). When compared to BP, pemphigus was associated with higher odds of osteopenia (1.59 [1.06-2.41]), osteoporosis (1.38 [1.18-1.63]), and fractures (1.26 [1.04-1.53]), particularly of the ulna and radius (3.17 [1.23-8.17]). Patients with pemphigus or BP as well as long-term systemic corticosteroid use had highest odds of osteoporosis and fractures. No data were available on treatments for pemphigus or BP. Pemphigus and BP were associated with osteopenia, osteoporosis, and pathologic fractures. Patients with PEM and BP may benefit from increased screening for osteoporosis and interventions to prevent fractures.

Abstract
Pemphigus is an autoimmune skin disease characterized by blistering and erosions of the skin and mucous membranes. Pemphigus is rare in Northern and Western Europe but its incidence is higher around the Mediterranean Sea. The most common type worldwide is pemphigus vulgaris. The aim of this study was to investigate the incidence of pemphigus subtypes in Northern Finland between 1985 and 2017. A total of 46 patients diagnosed with pemphigus at the Department of Dermatology of Oulu University Hospital were found the female/male ratio was 1.7. In contrast to many other countries it was found that in Northern Finland the superficial pemphigus subtypes were the most common: erythematosus or foliaceus (65%) followed by pemphigus vulgaris (26%). Over the past 4 decades the annual incidence of pemphigus in Finland has increased from 0.76 to 2.8 cases per million persons.

Abstract
Pemphigus vulgaris is a chronic autoimmune bullous dermatosis that results from the production of autoantibodies against desmogleins 1 and 3. It is the most frequent and most severe form of pemphigus, occurring universally, usually between 40 and 60 years of age. It usually begins with blisters and erosions on the oral mucosa, followed by lesions on other mucous membranes and flaccid blisters on the skin, which can be disseminated. There is a clinical variant, pemphigus vegetans, which is characterized by the presence of vegetating lesions in the large folds of the skin. Clinical suspicion can be confirmed by cytological examination, histopathological examination, and direct and indirect immunofluorescence tests. The treatment is performed with systemic corticosteroids, and immunosuppressive drugs may be associated, among them azathioprine and mycophenolate mofetil. More severe cases may benefit from corticosteroids in the form of intravenous pulse therapy, and recent studies have shown a beneficial effect of rituximab, an anti-CD20 immunobiological drug. It is a chronic disease with mortality around 10%, and septicemia is the main cause of death. Patients need long-term and multidisciplinary follow-up.

Abstract
The coexistence of pemphigus and systemic lupus erythematosus (SLE) had been reported anecdotally. Anti-desmoglein (Dsg)1 and anti-Dsg3 antibodies were detected concomitantly with antinuclear autoantibodies among blood donors. The aim of the current study was to study the association between pemphigus and SLE in Israeli patients and to synthesize existing data on this association in the current literature. The current study included two sections. Initially, a cross-sectional study was performed to compare pemphigus patients with age-, sex-, and ethnicity-matched control subjects regarding the prevalence of SLE using a real-life large-scale computerized database. Next, a systematic review and meta-analysis of similar observational studies in Medline, Embase, and Web of Science (1823-2017) was conducted. As for the cross-sectional study, a total of 1985 patients with pemphigus and 9874 controls were included in the study. The prevalence of SLE was slightly higher among patients with pemphigus as compared to controls (OR, 1.85; 95% CI, 0.89-3.82). In a sensitivity analysis that included patients who received pemphigus-related treatments, the association between pemphigus and SLE had been substantiated and was statistically significant (OR, 2.10; 95% CI, 1.00-4.48). In the meta-analysis section, three eligible studies, comprising 10,389 pemphigus patients met the eligibility criteria. The overall pooled multivariate OR was 2.50 (95% CI 1.54-4.07, I2 = 44.19%, P = 0.167) across all studies. In conclusion, the meta-analysis provides epidemiologic evidence that these B cell-driven diseases are significantly associated. Further research is required to elucidate the molecular mechanism underlying this association.

Abstract
Fogo selvagem or endemic pemphigus foliaceus is an autoimmune acantholytic anti-cadherin bullous disease that primarily affects seborrheic areas, which might disseminate. Brazil has the world's largest number of patients, mainly in the Central-West region, but the disease has also been reported in other South American countries. It affects young people and adults who have been exposed to rural areas, with occurrence of familial cases. Anti-desmoglein-1 autoantibodies are directed against desmosomal structures, with loss of adhesion of the upper layers of the epidermis, causing superficial blisters. The etiology is multifactorial and includes genetic, immune, and environmental factors, highlighting hematophagous insect bites; drug-related factors are occasionally involved. Flaccid blisters readily rupture to yield erosive-crusty lesions that sometimes resemble seborrheic dermatitis, actinic keratosis, and chronic cutaneous lupus erythematosus. The clinical presentation varies from localized to disseminated lesions. Clinical suspicion should be confirmed with histopathological and immunofluorescence tests, among others. The progression is usually chronic, and therapy varies according to clinical presentation, but generally requires systemic corticosteroid therapy associated with adjuvant immunosuppressive treatment to decrease the adverse effects of corticosteroids. Once the disease is under control, many patients remain stable on low-dose medication, and a significant proportion achieve remission.

Abstract
The association between pemphigus and hepatitis viruses has not been investigated sufficiently and remains unclear. Our objective was to assess the association between pemphigus and chronic hepatitis B (HBV) and hepatitis C (HCV) infections using a large-scale real-life computerized database. This study was conducted as a cross-sectional study utilizing the database of Clalit Health Services. The proportion of chronic HBV and HCV infections was compared between patients diagnosed with pemphigus and age-, sex-, and ethnicity-matched controls. Univariate analysis was performed using chi-square and Student's t test, and multivariate analysis was performed using a logistic regression model. A total of 1985 pemphigus patients and 9874 controls were enrolled in the study. The prevalence of HBV chronic infection in patients with pemphigus was significantly higher than in control subjects (1.2 vs. 0.6%, respectively, p = 0.008). The prevalence rate of HCV carrier state was comparable between pemphigus patients and control subjects (1.1 vs. 1.0, respectively, p = 0.732). A multivariate analysis revealed a significant association between pemphigus and HBV with a multivariate odds ratio (OR) of 1.9 [95% confidence interval (CI), 1.2-3.90], whereas no association between pemphigus and HCV was identified (OR 1.1, 95% CI, 0.7-1.7). In conclusion, patients with pemphigus have a greater proportion of chronic HBV but not HCV infection relative to matched controls.

Abstract
OBJECTIVES Recent evidence suggests a notable role for inflammation and immune dysregulation in the neuroprogression of bipolar disorders (BD). Several autoimmune comorbidities have been reported in association with BD. However, the epidemiological relationship between pemphigus and BD has not yet been elucidated. We aimed to estimate the association between pemphigus and BD using a large-scale, real-life computerized database. METHODS Data for this study were retrieved from the database of the Clalit Health Services, the largest, state-mandated, health service organization in Israel. This study was designed as a cross-sectional study. The proportion of patients with BD was compared between patients diagnosed with pemphigus and age-, sex-, and ethnicity-matched control subjects. A logistic regression model was performed to estimate how pemphigus and other covariates contributed as risk factors for BD. RESULTS A total of 1,985 pemphigus cases and 9,874 controls were included in the study. The prevalence of BD was greater in cases with pemphigus than in controls (1.0% v. 0.5%, respectively; P = 0.023). This coexistence was more prominent among patients of Jewish ethnicity. After controlling for confounders, such as age, sex, ethnicity, socioeconomic status, drug abuse, alcohol abuse, smoking, healthcare utilization, and comorbidities, pemphigus demonstrated a substantial independent association with BD (OR, 1.7; 95% CI, 1.0 to 2.9). CONCLUSIONS Pemphigus is significantly associated with BD. Patients with pemphigus should be assessed for comorbid BD. Experimental research is needed to better recognize the biological mechanisms underlying this observation.

Abstract
Pemphigus is an autoimmune disease characterized by intraepithelial bullae and erosions in the skin and mucosa. We aimed to evaluate the clinical and demographic characteristics of pemphigus vulgaris (PV) patients who presented to our Department. Patients who presented to our Department between May 2013 and May 2014, were examined dermatologically and diagnosed with PV based on clinical, histological and direct immunofluorescent findings. Name, family name, and gender of the patients, their complaint at presentation, onset time and location of the lesions, the number of lesions, systemic treatments received by patients and patients' medication histories were recorded. Forty-nine PV patients were included in our study. Among these, 22 (44.9%) were female and 27 (55.1%) male. The mean age of the patients was 53.28±14.70 (range 23 to 79) years. The mean duration of the disease was 44.45±45.68 (range 1 to 180) months. The most common complaints at presentation were lesion in the mouth (47/49) and lesion/blister in the skin (39/49). The onset locations of the lesions were the oropharynx (63.3%), the skin and oropharynx combined (16.3%), the skin (18.4%) and the anus (2%). The chronological order for the sites of involvement were as follows: first the oropharynx then the skin (42.9%), first the skin then the oropharynx (18.4%), and the oropharynx and the skin combined (16.3%). Ten patients (20.4%) had mucosal involvement and one (2%) had skin involvement alone, whereas both mucosal and skin involvements were observed in 38 patients (77.6%). Forty-seven patients (95.9%) had not used any medications that could have led to pemphigus. One patient had a history of beta-blocker use and another had a history of ACE inhibitor prior to the emergence of the pemphigus lesions. The clinical and demographic results of the PV patients in our region were consistent with those from other studies.

Abstract
Fogo Selvagem (FS), the endemic form of pemphigus foliaceus, is mediated by pathogenic IgG4 autoantibodies against the amino-terminal extracellular cadherin domain of the desmosomal cadherin desmoglein 1 (Dsg1). Here we define the detailed epitopes of these pathogenic antibodies. Proteolytic footprinting showed that IgG4 from 95% of FS donor sera (19/20) recognized a 16-residue peptide (A129LNSMGQDLERPLELR144) from the EC1 domain of Dsg1 that overlaps the binding site for an adhesive-partner desmosomal cadherin molecule. Mutation of Dsg1 residues M133 and Q135 reduced the binding of FS IgG4 autoantibodies to Dsg1 by ∼50%. Molecular modeling identified two nearby EC1 domain residues (Q82 and V83) likely to contribute to the epitope. Mutation of these residues completely abolished the binding of FS IgG4 to Dsg1. Bead aggregation assays showed that native binding interactions between Dsg1 and desmocollin 1 (Dsc1), which underlie desmosome structure, were abolished by Fab fragments of FS IgG4. These results further define the molecular mechanism by which FS IgG4 autoantibodies interfere with desmosome structure and lead to cell-cell detachment, the hallmark of this disease.

Abstract
Little is known about differences in epidemiological features and prognosis between pemphigus vulgaris (PV) and pemphigus foliaceus (PF). The objective of this study was to compare PV and PF patients regarding ethnic variations and mortality rates. Mortality of PV and PF patients was compared with age- and sex-matched control subjects in the general population. The study cohort comprised 207 patients with PV and 30 with PF diagnosed during the period 2000 to 2015. The incidence rate of PV among Jews was 3.6-fold higher than among Arabs (p<0.001), whereas no ethnic predisposition to PF was noted (p = 0.379). The risk of death for patients with PV was almost 3-fold higher than in the general population (standardized mortality ratio (SMR) 2.6). For patients with PF, the risk of mortality was not significantly increased relative to the general population (SMR 1.4). There is a racial predisposition to PV, whereas PF is sporadic. Mortality among patients with PV is higher compared with PF and the general population.

Abstract
Pemphigus is a group of rare and life-threatening autoimmune blistering diseases of the skin and mucous membranes. Although they occur worldwide, their incidence shows wide geographical variation, and prospective data on the epidemiology of pemphigus are very limited. Objective of this work is to evaluate the incidence and epidemiological and clinical features of patients with pemphigus in Turkey. All patients newly diagnosed with pemphigus between June 2013 and June 2014 were prospectively enrolled in 33 dermatology departments in 20 different provinces from all seven regions of Turkey. Disease parameters including demography and clinical findings were recorded. A total of 220 patients were diagnosed with pemphigus during the 1-year period, with an annual incidence of 4.7 per million people in Turkey. Patients were predominantly women, with a male to female ratio of 1:1.41. The mean age at onset was 48.9 years. Pemphigus vulgaris (PV) was the commonest clinical subtype (n=192; 87.3%), followed by pemphigus foliaceus (n=21; 9.6%). The most common clinical subtype of PV was the mucocutaneous type (n=83; 43.2%). The mean Pemphigus Disease Area Index was 28.14±22.21 (mean ± Standard Deviation). The incidence rate of pemphigus in Turkey is similar to the countries of South-East Europe, higher than those reported for the Central and Northern European countries and lower than the countries around the Mediterranean Sea and Iran. Pemphigus is more frequent in middle-aged people and is more common in women. The most frequent subtype was PV, with a 9-fold higher incidence than pemphigus foliaceus.

Abstract
Autoimmune bullous diseases (ABDs) are uncommon but significant skin disorders with relatively high morbidity and mortality. Some surveys have been carried out to describe the spectrum of ABDs in a region, but this is the first that has focused on ABDs in elderly patients. This study was conducted to determine the clinicoepidemiologic features of ABDs in elderly patients. Medical records of all ABD patients with disease onset after the age of 60 years who presented to the Autoimmune Bullous Diseases Research Center, Tehran, Iran between April 2003 and March 2013 were reviewed. Patients with dermatitis herpetiformis were not included. During the 10-year period studied, 296 patients with ABD and disease onset after 60 years of age were diagnosed. Bullous pemphigoid (BP) was observed to be the most common ABD (48.3%), followed by pemphigus vulgaris (45.3%), pemphigus foliaceus (3.7%), mucous membrane pemphigoid (1.4%), paraneoplastic pemphigus (0.7%), epidermolysis bullosa acquisita (0.3%), and linear IgA bullous disease (0.3%). A predominance in women was observed for total ABDs, BP, and pemphigus vulgaris. Although Iran is known to have a high prevalence of pemphigus, BP is the most frequent ABD among elderly patients in Iran, highlighting the importance of the clinical diagnosis of BP in elderly patients.

Abstract
Characteristics of autoimmune bullous diseases (AIBDs) show wide geographic variation. The aim of this study was to determine retrospectively the characteristics of patients with AIBD admitted to Hôtel-Dieu de France Hospital in Beirut, Lebanon, between 1999 and 2014 and to compare them with those from other areas in the Middle East, the Far East, Asia, North Africa, Europe, and North America. For the patients with AIBDs and who were hospitalized at a major tertiary referral center between 1999 and 2004, we studied demographics, diagnosis, length of stay, department/floor, comorbidities, clinical features, in-hospital evolution, diagnostic tests, and treatment. Bullous pemphigoides was the most frequent bullous disease in Lebanon. This and other findings contrast with those of studies conducted in regional countries. This is the first report of AIBD from the Middle Eastern region.

Abstract
BACKGROUND Little is known about the epidemiology of pediatric autoimmune blistering disorders (PAIBD). OBJECTIVE We sought to determine the inpatient burden and comorbidities of PAIBD. METHODS We analyzed data from the Nationwide Inpatient Sample from 2002 to 2012, which contained a representative 20% sample of all US hospitalizations. RESULTS The most common PAIBD with a primary admission was pemphigus (8.0 per million), whereas the most common secondary diagnosis of PAIBD was dermatitis herpetiformis (DH; 9.6 per million). Bullous pemphigoid (BP) was inversely associated with being female and having government or no insurance but positively associated with Black and Hispanic race/ethnicity and more chronic conditions. Pemphigus was associated with being female, Hispanic, having government or no insurance, and having a higher number of chronic conditions. DH was inversely associated with non-White race but positively associated with having government insurance and more chronic conditions. BP was associated with dialysis, hypertension, and diabetes. Pemphigus was associated with osteoarthritis, renal failure, hypothyroidism, and weight loss. DH was associated with herpes simplex virus infection, rheumatoid arthritis, and fungal, viral, and other skin infections. CONCLUSION PAIBD are associated with a considerable inpatient burden and comorbid health conditions.

Abstract
Background: Intravenous immunoglobulin (IVIG) therapy is widely used in immune-mediated diseases as an immunomodulatory agent and is considered to be a safe biologic agent. Objective: To determine the frequency of adverse events associated with IVIG therapy in patients with pemphigus and pemphigoid. Methods: We retrospectively reviewed data on patients treated with IVIG for pemphigus and pemphigoid over a 10 year period. Patients had pemphigus vulgaris, pemphigus foliaceus, mucous membrane pemphigoid, or bullous pemphigoid. IVIG was given according to a published protocol at a dose of 2 g/kg administered over 3–5 days at prescribed intervals. Patient records were reviewed for information on sex, age, duration of treatment, number of cycles given, number of days each patient received IVIG, weight of each patient, IVIG dose each patient received per infusion, and early or delayed adverse effects reported by patients or observed by healthcare providers. Results: We identified 9892 infusions given to 174 patients. Headaches were the most common adverse effects; they were observed during 886 (8.9%) infusions and involved 123 (70.6%) patients. The incidence of other minor adverse effects, including fatigue, nausea, vomiting, chills, urticaria, swollen glands, hoarseness, thoracic discomfort, and palpitations, was 0.57–3.4% per infusion and 0.04–1,3% per patient. Hoarseness of voice and swelling of cervical lymph nodes have not been previously reported. Acute renal failure occurred in one patient and was the only major adverse effect observed. None of the patients required hospitalization, and there were no deaths. Conclusions: Adverse events associated with IVIG therapy are usually mild and self-limiting. The incidence of serious adverse events is low. Identification of risk factors and close monitoring of high-risk patients throughout the therapy are likely to decrease the occurrence of rare serious and less likely fatal adverse effects.

Abstract
Pemphigus represents a group of organ specific autoimmune blistering disorders of the skin mediated by pathogenic autoantibodies with well-defined antigenic targets. While most of these diseases are sporadic, endemic forms of disease do exist. The endemic form of pemphigus foliaceus (also known as fogo selvagem, FS) exhibits epidemiological features that suggest exposure to hematophagous insect bites are a possible precipitating factor of this autoimmune disease, and provides a unique opportunity to study how environmental factors contribute to autoimmune disease development. FS patients and healthy individuals from endemic regions show an autoreactive IgM response that starts in early childhood and becomes restricted to IgG4 autoantibodies in FS patients. In searching for triggering environmental antigens, we have found that IgG4 and IgE autoantibodies from FS patients cross-react with a salivary antigen from sand flies. The presence of these cross-reactive antibodies and antibody genetic analysis confirming that these antibodies evolve from the same naïve B cells provides compelling evidence that this non-infectious environmental antigen could be the initial target of the autoantibody response in FS. Consequently, FS serves as an ideal model to study the impact of environmental antigens in the development of autoimmune disease.

Abstract
Pemphigus vulgaris (PV) is a rare, potentially life threatening, autoimmune blistering skin disease. The International Pemphigus and Pemphigoid Foundation (IPPF) has recently developed a disease registry with the aim to enhance our understanding of autoimmune bullous diseases with the long-term goal of acquiring information to improve patient care. Patients were recruited to the IPPF disease registry through direct mail, e-mail, advertisements, and articles in the IPPF-quarterly, -website, -Facebook webpage, and IPPF Peer Health Coaches to complete a 38-question survey. We present here the initial analysis of detailed clinical information collected on 393 PV patients. We report previously unrecognized gender differences in terms of lesion location, autoimmune comorbidity, and delay in diagnosis. The IPPF disease registry serves as a useful resource and guide for future clinical investigation.

Abstract
Pemphigus, a rare, chronic blistering disease of the skin and mucous membranes with severe morbidity and occasional mortality, is the most common autoimmune bullous disease in Korea. The purpose of this study was to evaluate the clinical features and propose a treatment strategy for patients with pemphigus. A retrospective analysis was conducted of 51 pemphigus patients seen between 1993 and 2001. Pemphigus vulgaris (PV) was the most common type with 32 cases, followed by 19 cases of pemphigus foliaceus (PF). The male to female ratio was 1:1.3, with females predominating, particularly among PV patients (PV, 1:1.5; PF, 1:1.1). The average ages at onset of PV and PF were 44.3 and 51.0 years old, respectively. Mucosal involvement was noted in 27 cases (84.4%) of PV but in only 3 cases (15.8%) of PF. Most patients initially received relatively low to intermediate doses (0.3-1.0 mg/kg/day) of prednisolone, and 23 (71.9%) PV patients and 10 (52.6%) PF patients also received immunosuppressive agents. Oral prednisolone and azathioprine (100 mg/day) formed the mainstay of treatment for our patients (47.1%). At the time of writing, 25.5% (13/51) of patients are in complete remission, and 72.5% (37/51) are undergoing maintenance therapy. One patient died due to sepsis during the treatment. For the treatment of pemphigus, a course of the lowest possible corticosteroid dosage in combination with immunosuppressive agents appears to be effective and less toxic than a high corticosteroid dosage.

Abstract
This study sought to assess and compare retrospective demographic and clinical data of oral lesions of lichen planus, pemphigus vulgaris, and mucous membrane pemphigoid from the records of the Department of Oral Pathology and Surgery, School of Dentistry, Universidade Federal de Minas Gerais, Brazil, covering a period of 55 years. Out of 25,435 specimens, these immunologically-mediated diseases accounted for 301 (1.18%) cases, of which 250 (0.98%) were lichen planus, 27 (0.11%) were pemphigus vulgaris, and 24 (0.09%) were mucous membrane pemphigoid. Lichen planus presented mainly as white asymptomatic plaques on buccal mucosa. Pemphigus vulgaris was usually characterized by multiple symptomatic erithematous ulcers on the buccal mucosa. Painful ulcers and/or blisters on the gingiva were the most common presentation for mucous membrane pemphigoid. Desquamative gingivitis was noted for all 3 diseases, but mainly for mucous membrane pemphigoid. Overall, lesions were more frequent in white women >50 years. Oral manifestations of immunologically-mediated diseases are relatively rare, and the correct diagnosis can be a challenge for dentists as the lesions often share similar clinical and demographic features.

Abstract
Polymorphism in the genes of TH2 cytokines and/or theirs receptors can influence serum cytokine levels in and the switch to the pathologic IgG4 auto-antibodies. In order to underline the role of these genes in the aethiopathogenesis of Pemphigus Foliaceus, we conduct a familial and a case control studies including 80 Tunisian patients, 147 related subjects and 160 matched healthy controls. We investigated, by PCR-RFLP technique, seven nucleotide polymorphisms: rs2243250 in promoter region of IL4 gene, rs47877948, rs3024530 and rs30246223 in the IL4R gene, rs1881457and rs205412 SNPs in IL13 gene and rs535036 in IL13RA2 gene. After Bonferroni adjustment, T allele and the TT genotype of IL4-590 were significantly increased in the PF patients group compared to healthy controls. This association was confirmed by the family study. Interestingly, the serum IL-4 levels were significantly increased in patients with the TT genotype compared to CT or CC genotypes. Interestingly, the IL4/IL13:T-A-C haplotype exhibited a significant effect on PF susceptibility. In addition, a significant gene-gene interaction between the IL4/IL4R (TACA) significantly increases in PF patients as compared to controls. These findings assess the role of the IL4/IL4R axis in the aethiopathogenesis of Tunisian endemic PF by the induction of a high transcriptional activity which could enhance the T-cell balance and inducing immunoglobulin isotype switching.

Abstract
Introduction In pemphigus, there still is no consensus on parameters mesuring clinically the disease severity. The aim of this study is to use the Japanese severity index in Moroccan patients with pemphigus. Methods Multicenter prospective study from September 2007 to September 2009 including consecutive patients with confirmed pemphigus. We used the Japenese severity index for pemphigus. For each patient, the score was calculated at diagnosis and at 6 months of follow-up and correlated to type of pemphigus; mean dosage of corticosteroids and clinical statuts at 6 months: dead or not. Results Fifty six patients were included, 20 men and 36 women, mean age 46.62 ± 15.9 years. At diagnosis, the mean initial score was 7.7 + 2.36; at six months, it was 1.61 + 1.83. The score variation at 6 months and inclusion was 6.19 ± 2.18 for deep pemphigus and 5.43 ± 2.85 for superficial pemphigus (p = 0,3 non significant). At six months, 4 patients were dead: their initial score was 11 + 1.41 while the initial score in the 52 patients was 7.4±2.03 (p = 0,001, significant). Data showed no correlation between initial severity scores and cumulative dosage of corticosteroids at 6 months (Pearson coefficient of correlation 0.144; p = 0.580). Conclusion In this study, initial severity scores for pemphigus were high and decreased at 6 months of treatment. Both deep pemphigus and superficial pemphigus were severe as their score variation was similar. Japenese severity score is useful for Moroccan patients with pemphigus.

Abstract
BACKGROUND Serum lactate is a useful prognostic marker in severe sepsis; high levels of serum lactate in critically ill patients are related to high mortality risk; assessing serum lactate levels in patients with pemphigus vulgaris is justified. The objective was to determine the role of serum lactate as a predictor of shock and its outcome in patients with pemphigus vulgaris and severe sepsis without acute organ dysfunction. METHODS Thirty-seven patients with pemphigus vulgaris, 22 with severe sepsis and 15 without sepsis. Blood lactate levels were analyzed. The outcome was recorded as survival or non-survival. RESULTS High serum lactate levels, compared with intermediate and low levels, were significantly associated with increased 28-day mortality in patients with severe sepsis. The 28-day mortality for the cohort was 27.3%. CONCLUSIONS Initial serum lactate was associated with mortality in pemphigus vulgaris with severe sepsis. Patients with severe sepsis and with high serum lactate levels (≥ 4 mmol/L) constitute a potential risk group that may benefit from more aggressive treatment.
