Abstract
Pemphigus is a life-threatening autoimmune blistering disease affecting skin and mucous membranes. Despite its etiopathogenesis remains largely unknown, several trigger and predisposing factors have been reported. Pemphigus is caused by autoantibodies that target desmoglein 1 and desmoglein 3, impacting desmosome function. However, circulating autoantibodies are often the consequence of a precipitating factor that occurs in predisposed individuals. This review aims to describe and discuss almost all trigger and predisposing factors reported as possible or probable cause of the disease. Among the reported trigger factors that may induce or exacerbate pemphigus, we have found of particular interest: drug intake (especially thiol- and phenol-containing compounds), vaccines, infections, as well as some reports about pregnancy, radiations, emotional stress, pesticides and physical trauma. Moreover, we discuss the possible role of food intake in pemphigus onset and particular attention is given to dietary factors containing thiol, phenol and tannin compounds. A trigger factor is "the straw that breaks the camel's back," and often acts together with predisposing factors. Here we discuss how pemphigus onset may be influenced by genetic susceptibility and comorbidities like thyroid diseases, malignancies and other autoimmune disorders. To identify other hitherto unknown trigger and predisposing factors, well designed prospective studies are needed. In this context, future research should explore their connection with the aim to advance our understanding of pemphigus pathogenesis.

Environmental factors in autoimmune bullous diseases with a focus on seasonality: new insights. Dermatol Reports 2023; 15:9641. [PMID: 37753233 PMCID: PMC10518530 DOI: 10.4081/dr.2023.9641] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Accepted: 02/08/2023] [Indexed: 09/28/2023] Open
Abstract
Autoimmune bullous diseases are a heterogeneous group of rare conditions clinically characterized by the presence of blisters and/or erosions on the skin and the mucous membranes. Practically, they can be divided into two large groups: the pemphigoid group and the pemphigus group, depending on the depth of the autoimmune process on the skin. A family history of autoimmune diseases can often be found, demonstrating that genetic predisposition is crucial for their development. Moreover, numerous environmental risk factors, such as solar radiation, drugs, and infections, are known. This study aimed to evaluate how seasonality can affect the trend of bullous pemphigoid and pemphigus vulgaris, especially considering the number of hospitalizations recorded over the course of individual months. The total number of hospitalizations in the twelve months of the year was evaluated. Moreover, blood chemistry assay and, for some patients, enzyme-linked immunosorbent assay were executed to evaluate antibodies. Regarding the severity of the disease, the bullous pemphigoid area index and the pemphigus disease area index score systems were used. Results showed a complex interplay between environmental factors such as seasons and autoimmune conditions.

The multifactorial complexities of autoimmune development in Pemphigus vulgaris: Critical evaluation of the role of environmental and lifestyle "exposome" factors. Front Immunol 2023; 13:1058759.

Abstract
Pemphigus vulgaris (PV) is a potentially life-threatening blistering disorder characterized by autoantibodies directed against cell-cell adhesion molecules that serves as an excellent model to study human autoimmune development. Numerous studies have identified specific Human Leukocyte Antigen (HLA) genes, in particular DRB1*0402 and DQB1*0503, that confer disease risk. Although HLA is required, it is not sufficient for the initiation of disease. As with all autoimmune diseases, the etio-pathogenesis of PV is complex, meaning it is multifactorial. Susceptibility is polygenic, and the search for non-HLA disease-linked genes continues. Moreover, twin studies across autoimmune conditions indicate that non-genetic environmental and lifestyle factors, which can be collectively grouped under the term "exposome", are also major contributors to disease development. The literature presents evidence for the potential role of multiple triggers such as medications, infections, stress, diet, immunizations, and sleep to influence the etiology, pathophysiology, and prognosis of PV. However, a clear understanding of the degree to which specific factors impact PV is lacking. In this investigation, we comprehensively review the environmental elements listed above and consider the strength of evidence for these factors. The overall goals of this work are to provide greater insights into the factors that influence disease susceptibility, disease development and disease course and ultimately help to better guide clinicians and inform patients in the management of PV.

Abstract
BACKGROUND While a plethora of literature continues to be published on the role of nutritional agents both in lay press and indexed journals, the data is not on a firm footing and leaves the dermatologist in a quandry and the patient confused. The various agents include vitamins, minerals, amino acids, antioxidants, diets & gluten. A proper knowledge of the role of nutritional supplements in dermatological diseases can be a useful tool in advising the patients and in certain cases ameliorating the disorder. PATIENTS/METHODS Literature review of last 15 years was made using the terms "diet in dermatology," "nutrition and skin," "nutritional supplements in dermatology," "nutritional agents and acne," "nutritional agents and alopecia," and "nutritional agents and psoriasis." RESULTS While there are multiple publications on the use of nutritional supplements for amelioration of skin diseases, most of them are based on either associations or in vitro studies, but very few transcend the rigors of a clinical trial or the holey grail of a double-blinded randomized controlled trial. There seem to be some evidence in acne, psoriasis, telogen effluvium, urticaria & vitiligo. Coeliac disease and dermatitis herpetiformis have a strong link with diet. Rosacea has a strong link with certain foods, but the other disorders like melasma, aphthous stomatitis do not have any scientifically validated association with diet. CONCLUSIONS Our updated review examines the role of nutritional supplements and antioxidants in various dermatological disorders. We have found that there are varying levels of evidence with notable associations of low glycemic diet & acne, fish oil & weight loss with psoriasis, fish oils & probiotics with atopic dermatitis & vitamins & botanical extracts with vitiligo. The evidence for diet and nutrition in bullous disorders and photoageing is scarce. The role of low histamine diet in urticaria is useful in select cases of episodic urticaria. Rosacea is triggered by hot and spicy food . Apart from gluten and Dermatitis Herpetiformis, no diet can be considered disease modifying in our reveiw. The lack of comparison of nutritional or dietary modiffication with conventional validated agents, makes the data difficult to translate in real world patient management.

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
Background Among exogenous etiologies, the critical role of microbial agents such as herpesviruses (HSV1/2) and cytomegalovirus (CMV) in triggering and flaring autoimmune conditions such as pemphigus vulgaris (PV) has been recently discovered. Objectives The present study aimed to investigate the plausible role of these viruses in the exacerbation of PV using serological and molecular methods. Patients/Methods Sixty patients with PV (30 with relapse type and 30 with remission type) were recruited for the purpose of this case-control study. Skin, mucosal, and throat specimens were obtained and examined for viruses by reverse transcriptase polymerase chain reaction. To determine the immunoglobulin G (IgG) titer, enzyme-linked immunosorbent assay was used. Results Desmoglein1-specific IgG was positive in 56.7% of patients with the relapse form and in 20.0% of those with the remission form indicating a significant difference across the 2 groups (P = 0.003), but the rate of positivity for desmoglein3-specific IgG in the relapse and remission types was 76.7% and 63.3%, respectively, with no significant difference (P = 0.260). There was no difference in the mean levels of HSV-IgG and CMV-IgG in the relapse and remission groups. HSV and CMV positivity in PV patients was independent of the site of the samples. Using the multivariable linear regression model, the level of CMV-IgG in PV patients was directly affected by female sex and advanced ages. Conclusions Our study could not demonstrate the role of HSV1/2 and CMV as triggering factors for PV exacerbation. Further studies are needed to evaluate the potential role of these viruses in PV exacerbation especially considering demographic variables.

Abstract
BACKGROUND Pemphigus typically has a chronic course, although there is great variability in disease duration (DD) and time taken to disease remission (DR) between individuals with the disease. The reasons for this are unclear. OBJECTIVES To explore the prognostic influence of epidemiological, clinical, immunological and genetic factors on disease course and remission in pemphigus vulgaris (PV) and pemphigus foliaceus (PF). METHODS This was a retrospective study of patients with PV and PF, recruited from a single UK centre. Direct and indirect immunofluorescence and enzyme-linked immunosorbent assay studies for antidesmoglein (Dsg) antibodies were used to assess immunological factors. Polymerase chain reaction with sequence specific primers (PCR-SSP) was used to assess the Class II human leukocyte antigen status of patients. Prognostic endpoints investigated were time to initial first DR and total DD. RESULTS Ninety-five patients were recruited (79 PV and 16 PF). Patients of Indo-Asian origin were significantly associated with longer DD than White-British patients (P = 0.029). In addition, younger age at onset was associated with a worse prognosis in terms of DD: the mean age at presentation of patients with DD of < 5 years was 49 years (SEM = 3.4) compared with 40 years (SEM = 1.9) in those with DD > 5 years (P = 0.039). A higher initial intercellular antibody titre on normal human skin substrate was associated with a greater time to initial DR (P = 0.007) and high anti-Dsg 3 levels at baseline were associated with a longer total DD (P = 0.03). CONCLUSIONS Ethnic group, age at presentation, initial intercellular antibody titre and initial Dsg 3 antibody levels all had a significant impact on prognosis of pemphigus.

Abstract
BACKGROUND Pemphigus shows geographically variable characteristics. OBJECTIVE To study the clinical and immunologic characteristics of Indian pemphigus patients before and after treatment. METHODS Twenty-six Indian pemphigus patients were analyzed with regard to age, gender, clinical features, treatments and response, the results of histopathology, direct and indirect immunofluorescence (IF), enzyme-linked immunosorbent assay (ELISA), and immunoblot analyses. RESULTS There were 22 pemphigus vulgaris (PV) and 4 pemphigus foliaceus (PF) patients. Direct and indirect IF was positive in 95.8% and 56% of patients, respectively. Indices of ELISA were lower in our study. Immunoblot assays detected the 130 kDa desmoglein-3 in 10 PV patients and the 160 kDa desmoglein-1 in 1 PV patient; 190 kDa periplakin was unexpectedly detected in 8 patients. CONCLUSION Indian pemphigus patients showed several unique characteristics, including younger population, predominance of PV, low ELISA indices, lower sensitivity of indirect IF and immunoblotting, and the presence of the 190 kDa periplakin in nearly one-third of patients.

Abstract
BACKGROUND Pemphigus is an autoimmune blistering disease. According to a report, in areas of endemic pemphigus foliaceus (EPF) in Peru there are cases of pemphigus vulgaris with epidemiologic, clinical and histopathologic characteristics similar to those of "endemic pemphigus vulgaris" (EPV) in Brazil. OBJECTIVES To determine the clinical and epidemiologic characteristics of endemic pemphigus and the risk factors of patients for developing complications during treatment. METHODS A study was carried out from July 2003 to March 2008. The study population was 60 patients with EPF and 7 patients with EPV evaluated in hospitals and clinics in the Peruvian Amazon and Lima. A multivariate analysis was carried out using binary logistic regression. RESULTS The average age of EPF patients was 31.4 years; 55% were men; 60% presented the generalized clinical variant. Non-compliance with the treatment was seen in 57.1% of the patients. Thirty-five percent presented complications (e.g. pyodermitis and pyelonephritis) during treatment. The risk factors for developing complications during treatment were non-compliance with the treatment and having the generalized clinical form. In the EPV group, the average age was 21.7 years; 71.4% were men. All patients presented with the mucocutaneous clinical variant and the initial presentation consisted of oral mucosa lesions; 71.4% presented complications during treatment, pyodermitis being the most frequent. CONCLUSIONS Non-compliance with the treatment and the generalized clinical form are risk factors for the development of complications during treatment of patients with EPF. Peru indeed has EPV cases with epidemiologic characteristics similar to EPF. Living in a rural area may represent a risk factor for the development of complications during treatment of patients with EPV.

Abstract
INTRODUCTION The relation between pemphigus and infection is complex. The aim of this work was to determine the frequency and impact of infection as well as the factors associated with it among our patients with pemphigus. METHODS This retrospective case series examined records of patients with pemphigus admitted to the dermatology unit of Ibn Sina University Hospital of Rabat between 1989 and 2004. We compared the patients with and without infections as well as the patients with and without severe bacterial infections according to patient profile and outcome. The principal outcome measure was death and the secondary measure, duration of hospitalization. RESULTS Of the 141 patients with pemphigus included in our study, 68% developed an infection. Infections were bacterial in 52% of cases, fungal in 50%, herpetic in 19% and parasitic in 1.5%. They were associated with diabetes mellitus and immunosuppressive drugs. Severe bacterial infection was frequent in patients with diabetes and rare in those treated with corticosteroids or with pemphigus foliaceous. Death occurred significantly more often among infected subjects (p=0.01), especially those with severe bacterial infections (p<0.001). Hospitalization was slightly longer among patients with infections (p=0.01) but shorter in cases of severe bacterial infections (p=0.004). DISCUSSION Our study confirms the predisposition to all types of infection among patients with pemphigus, as well as the undeniable role its treatment plays in promoting infection. Severe bacterial infections were most often contracted before hospitalization. The literature reports a wide variety of infections, with pemphigus-herpes documented most often. Prevention and management require hygienic measures as well as early diagnosis and treatment of pemphigus and infections. Preventive treatment may be considered, but studies are needed to define the patients who might benefit from it.

Abstract
A possible mechanism for phenol-induced pemphigus lesions in genetically predisposed individuals is proposed that accounts for in vitro observations and cases of biochemical acantholysis, as well as the in vivo acantholysis in pemphigus induced by phenols. The mechanism involves the induction of interleukin-1a and tumor necrosis factor-a release by keratinocytes. These cytokines in turn have been shown to be involved in the regulation and synthesis of complement and proteases like plasminogen activator, which have been implicated in the pathogenesis of acantholysis in pemphigus vulgaris.

Abstract
BACKGROUND Endemic pemphigus foliaceus (EPF) or fogo selvagem (FS) is an endemic autoimmune disease, characterized by flaccid bullae induced by IgG(4) subclass antibodies. The authors demonstrate the epidemiological and clinical status of patients who have been followed at the University Hospital of Brasilia (HUB) for more than 15 years. METHODS One hundred and ninety-six patients with FS took part in the project. In setting up this study a historical descriptive cohort of patients was put together. In order to collect data, the authors used a questionnaire where the patient indicated the sex, age at the onset, occupation, origin, clinical status, including scalp compromise, evolution, cofactors influencing clinical worsening and the treatment compliance. In order to minimize loss to follow up, the authors used the statistical method of incidence density (patients/years). RESULTS The disease occurred in 58.4% of the young patients in the 11-30-year age bracket, and 52% came from urban areas. These patients included students and teachers. Localized disease predominated as compared with the generalized presentation of this condition. Fifty-nine percent of the patients evolved to the recurrent form. Those patients with the evolutional form, in remission for more than 1 year (94%), had been followed for more than 5 years. Even patients with the less active forms of the disease had scalp lesions. Thus scalp lesions are not an indicator of bad prognosis. CONCLUSIONS In the present study, the disease affected patients from a higher sociocultural class than previously described. Furthermore, in contrast to other reports, a substantial number of the patients lived in urban areas, although often spending some time in a rural setting for leisure or professional activities. This study suggests that the longer the follow up, the higher the likelihood that the disease would progress to a more controlled clinical presentation. Scalp lesions were not related to adverse prognosis. Sun, heat and infections act as triggering factors for the immunological imbalance, worsening the disease.

Abstract
A 56-year-old Jewish woman of Ashkenazi origin had a history of tuberculosis since the age of 1 year, contracted while she was in hiding in Poland during the Holocaust. She developed bronchiectasis in 1972 for which she was being treated 4 times a year for 1-month periods with 600 mg/d rifampin. During the Persian Gulf War in February 1991, a month after a rifampin treatment, she was admitted to the dermatology department with cutaneous and oral mucous eruptions. Physical examination revealed crusting bullae and erosions on the trunk and lower limbs. The mucous membranes were affected in the vagina, oral cavity, and pharynx. Histologic and immunofluorescence studies on a biopsy specimen confirmed the diagnosis of pemphigus vulgaris. There was no family history of the disease. Systemic treatment with prednisone,100 mg/d, resulted in regression of the eruption within a month, and the dose was tapered to 10 mg every second day. Although she received anti-tuberculosis treatment, the steroids caused an exacerbation of the tuberculosis, and after a massive hemoptysis in 1993, a right upper and middle lobectomy was performed. The operation put an end to the vicious cycle of drug-induced pemphigus outbreaks by eliminating the need for rifampin, but the patient reported the appearance of new lesions during periods of emotional stress.

Abstract
Pemphigus is an autoimmune disease that results from the interaction between predisposing genetic factors and exogenous factors, the most common environmental factors being drugs and food. Topical phenol has induced pemphigus in one patient. Drugs and foods that induce pemphigus are divided into three main groups according to their chemical structure: thiols (containing a sulfhydryl group), phenol, nonthiol nonphenol. Thiol and phenol compounds can induce acantholysis in tissue cultures in vitro. The suggested mechanisms for thiol acantholysis include direct biochemical impairment of cell adhesion, protease activation and immunological reaction with the formation of a neoantigen. Possible mechanisms of phenol-induced pemphigus include the induction of IL-1alpha and TNF-alpha release by keratinocytes. These cytokines have been shown to be relevant in the regulation and synthesis of complement and proteases, like plasminogen activator, which has been implicated in the pathogenesis of acantholysis in pemphigus vulgaris. Avoiding exposure of genetically predisposed individuals to these factors is important in treating and preventing this disease.

Abstract
BACKGROUND Pemphigus is an autoimmune disease which is more frequently seen in certain ethnic groups such as Jews. It is thought that exogenous factors may induce pemphigus in genetically predisposed individuals. Recent reports on HLA antigens indicate an increased frequency of HLA-class II antigens particularly HLA-DR4 among Jewish patients. Herein we investigated the antigen frequencies of HLA-A, B, C, HLA-DR and DQ in Turkish patients with pemphigus. METHODS HLA class I and II antigens were typed by microdroplet lymphocyte cytotoxicity test in 33 patients with pemphigus and 100 healthy individuals. RESULTS HLA-B35, B44, CW4, DR4, DR14, DQ8 and DQ4 antigens were significantly high in the study group whereas HLA-DR11, DQ7 and DQ2 antigens were high among the controls. The most striking differences were observed in HLA class II antigens. HLA DR14-DQ8 and HLA B35-DR14 haplotypes were the most frequently observed ones in the study group. CONCLUSIONS We postulate that HLA-B35, B44, CW4, DR4, DR14, DQ4 and DQ8 antigens may be responsible for susceptibility to pemphigus while HLA-DR11, DQ7 and DQ2 antigens may have a protective role in the Turkish population.

Abstract
BACKGROUND There have been reports suggesting the involvement of environmental factors in the disease process of pemphigus. Factors suggested include exposure to pesticides or certain drugs. OBJECTIVE To analyze the association of pemphigus with environmental exposure to various agents, including smoking, recreational and occupational insults, drugs, and food. DESIGN AND SETTING In-person interviews of pemphigus patients and control subjects were conducted by trained medical investigators using a structured questionnaire. Questions included occupational, behavioral, medical, and qualitative food frequency details. The multicenter study was conducted at outpatient services of teaching hospitals in Bulgaria, Brazil, India, Israel, Italy, Spain, and the USA. PARTICIPANTS A total of 126 pemphigus patients (55 men, 71 women; age, 54 +/- 17 years) and 173 healthy controls (87 men, 86 women; age 50 +/- 19 years) were interviewed in the period between October 1, 1999 and March 31, 2000. The diagnosis of pemphigus was based on clinical, histologic, immunohistologic, and immunohistochemical criteria. The disease duration was 2-27 years (8.4 +/- 7.2 years). Individuals with skin diseases other than pemphigus were selected as control subjects. MAIN OUTCOME MEASURE Information on drugs, foods, and occupational, environmental, constitutional, and other possible risk factors was analyzed by t-tests and chi-squared tests as applicable. A multivariate logistic regression model was applied to the data to study simultaneously the independent relationship between each risk factor and pemphigus vulgaris. RESULTS The risk for pemphigus vulgaris was lower for ex-smokers and current smokers than for patients who had never smoked. Exposure to pesticides and occupational exposure to metal vapor were associated with an increased risk of pemphigus. Pemphigus patients had more pregnancies than controls. There were differences in environmental factors between countries, with exposure to gardening materials and pesticides being highest among patients from Bulgaria, followed by Israel. Disease characteristics also exhibited differences between countries. Bulgarian patients less frequently had oral mucous membrane lesions: 66% compared to 92% for Israeli patients and 83% for Italians. The distribution of the disease in skin and mucous membranes was similar among patients from all countries. Exclusive skin involvement was seen in 50% of patients, mucous membranes alone in 23% of patients, and both skin and mucous membranes in 27% of patients. CONCLUSIONS The beneficial effect of smoking on pemphigus might be explained by its effect on the immune system. In addition, smoking has an antiestrogenic effect, while pesticides have an estrogenic effect. The lower numbers of smokers among patients, the higher exposure rates to pesticides, and the higher number of female patients who had been pregnant may point to the contribution of estrogens to the disease process. It remains to be determined whether measures, such as avoiding exposure to pesticides or metal vapor, may be beneficial in the clinical context. As the present study was a survey, more definitive studies should be conducted to validate the results.

Abstract
BACKGROUND Exogenous factors, such as certain drugs, may be involved in the induction of pemphigus. Other offenders sharing a similar chemical composition to these drugs may also play a role. Tannins with their considerable biologic activity were suggested as possible factors. To substantiate the role of tannins in the pathomechanism of pemphigus, the present study examined the acantholytic potential of tannins in vitro. METHODS Normal human breast skin from patients without any bullous disease was cultured for 3 days in the presence of tannic acid at concentrations of 0.02, 0.05, 0.1, 0.25, 0.5, 1.0, and 2.0 mM. The effect of the tannic acid was microscopically examined in a blind fashion by three independent investigators. RESULTS In addition to the cytotoxic effect, tannic acid caused marked acantholytic changes, with a clear suprabasal cleavage and intraepidermal acantholytic cells. The acantholytic changes were the most constant and specific effects. They were constantly observed at 1.0 and 2.0 mM, whereas lower concentrations showed changes only in some of the explants. The concentrations needed to exert this effect were notably low. There was a remarkable variability among the subjects who had provided the explants. CONCLUSIONS The results suggest a possible role of tannin in the disease process of pemphigus. The tannin acantholytic potential was much greater than the potential of known acantholytic drugs, such as penicillamine and captopril. The interindividual variability in susceptibility to acantholysis may explain the variability in the individual potential for developing pemphigus.
