Abstract
Neural epidermal growth factor-like 1 (NELL1) membranous nephropathy (MN) is notable for its segmental deposit distribution, IgG1 dominant deposits, and comparatively high rate of spontaneous remission. It has been associated with a variety of exposures and secondary conditions, specifically use of thiol-containing medications - including lipoic acid, bucillamine, and tiopronin - as well as traditional indigenous medications (TIM) particularly those with high mercury content, and non-steroid anti-inflammatory drugs (NSAIDs). Malignancies, graft vs. host disease (GVHD), infection, and autoimmune conditions have also been associated with NELL1 MN. Herein, we provide a detailed summary of the clinicopathologic features of NELL1 and associations with underlying conditions, with a focus on treatment and outcomes. Rare cases of dual NELL1 and phospholipase A2 receptor (PLA2R) positive MN are reviewed. Genome-wide association study of NELL1, role of NELL1 in other physiologic and pathologic processes, and connection between NELL1 MN and malignancy with relevance of NELL1 tumor staining are examined. Finally, relationships and potential disease mechanisms of thiol- and mercury- associated NELL1 MN are discussed.

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.

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
Periodontal and chronic oral mucosal diseases are significant life impacting conditions which may co-exist and synergistically act to cause more severe and widespread oral pathology with enhanced challenges in effective management. Clinicians regularly observe these effects and struggle to effectively manage both problems in many patients. There is limited understanding of many basic and applied scientific elements underpinning potentially shared aetiopathological features and management. Recent developments in translational science provide an opportunity to greater improve knowledge and subsequently care for patients with these problems.

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

Abstract
Pemphigus vulgaris is an autoimmune blistering disease with an increased potential for mortality. The epithelium is key in understanding the pathobiology as it is specialized to perform functions like mechanical protection, immunological defense, and proprioception. In order to perform these array of functions, epithelial integrity is important. This integrity is maintained by a host of molecules which orchestrate the ability of the keratinocytes to function as a single unit. Desmoglein 3 antibodies formed in genetically susceptible individuals are known to cause the disruption of the intact oral mucosa leading to the formation of blisters in pemphigus vulgaris patients. However, there are underlying complex triggering pathways leading to the clinical disease. The aim of the review is to congregate and critically appraise the various triggering pathways which contribute toward the pathobiology of pemphigus vulgaris. Articles relevant to the pathobiology of pemphigus vulgaris were identified from various search databases till the year 2020. The pathogenesis of pemphigus vulgaris is complex, and it involves an in-depth understanding of the various predisposing factors, provoking factors, and progression mechanisms. Congregation of the various triggering pathways will open our minds to understand pemphigus vulgaris better and in turn develop a reliable treatment in the near future.

Abstract
Pemphigus encompasses a rare heterogeneous group of autoimmune blistering diseases characterized by cutaneous and/or mucosal blistering. Multiple factors, such as some specific types of drugs, have been found to be involved in the induction of pemphigus. Here, we have designed a systematic review by searching PubMed/Medline and Embase databases to find the drugs, involved in pemphigus induction and exacerbation (updated on 19 August 2019). From 1856 initially found articles, 134 studies (198 patients; 170 patients in the drug-induced patients and 28 in exacerbation group) have been included. Regarding drug-induced cases, the mean age was 57.19 ± 16.9-year-old (ranged 8-105), and patients had developed pemphigus within a mean of 154.27 days. Pemphigus vulgaris (38.9%), pemphigus foliaceus (33.5%), and paraneoplastic pemphigus (3.6%) were the most common subtypes. Furthermore, penicillamine (33.1%), captopril (7.7%), and bucillamine (6.5%) were the most reported drugs related to pemphigus induction; penicillamine was associated with the most persistent disease. Regardless of disease subtype, cutaneous, mucocutaneous, and mucosal involvements were reported in 68.6%, 30.1%, and 1.3% of patients, respectively. In total, the IgG deposition in the pathological studies, being positive for autoreactive antibodies in the serum against desmoglein 3 (Dsg3), and desmoglein 1 (Dsg1), were reported in 93%, 34.9%, and 72.7% of reported patients, respectively. Regarding the management of such patients, in 75% of healed cases, treatment (mainly transient systemic and topical corticosteroids and/or azathioprine) was needed besides stopping the probable pemphigus-inducing culprit drug, while drug cessation was enough to control the disease in 25%. As the outcomes, the lesions in 129 of 147 (87.8%) patients had been healed, while in 18 (12.2%), no healing was reported; fifteen out of 18 had died. In conclusion, some specific groups of treatments can induce pemphigus, including penicillamine, captopril, and bucillamine; despite the similar clinical and pathological manifestations to classical pemphigus, most of the cases are less severe and have a better prognosis.

Abstract
Introduction & Objectives:
Cutaneous and systemic reactions to various metal implants and
medical devices have been well documented. The aim of this review was to focus on the probable
common mechanisms of allergy and autoimmunity that may lead to similar clinical outcomes following
the growing evidence in the literature of metal and nickel-related systemic, autoimmune or autoinflammatory
disorders.
Methods:
Detailed search of the available electronic databases (PubMed-Medline) was conducted for
review of the literature on that topic till the present moment.
Results:
Multiple reports on the immunological effects of metals including immunomodulation, allergy,
or autoimmunity were identified. It was found that metals may act through immunosuppression,
immunotoxicity, or as immune adjuvants thus provoking allergy and autoimmunity in susceptible individuals.
Both external or internal exposure to metals was observed. Nickel has been identified as the
most common sensitizer, and also the most studied one. The coexistence of both allergic and autoimmune
symptoms, induced by nickel, has been published, suggesting the autoimmune potential of nickel
compounds.
Conclusions:
Clinical experience and scientific literature together demonstrate that metals may play an
important role in the development of autoimmune diseases. While metal implant allergies and complications
are on the rise, they remain a diagnostic and therapeutic challenge. Elucidation of their possible
mechanisms will contribute to the more successful and safer treatment of affected individuals.

Abstract
Pemphigus is a group of autoimmune diseases characterized by the formation of erosions and/or flaccid bullae of the skin and/or mucosae. The definition "drug-induced pemphigus" has been coined to indicate cases of pemphigus with clinical, histological and immunopathologic features similar to those of the idiopathic disease but induced by systemic ingestion or local use of some drugs. The present authors analyzed a case series of three case reports with clinical and pharmacological features compatible with the diagnosis of angiotensin converting enzyme inhibitors or angiotensin II receptor blocker drug-induced pemphigus. The patients were visited by the dermatological Unit of Magna Graecia University in Catanzaro. All suspected drug induced pemphigus were treated by suspending the suspected drug and by starting a treatment with systemic corticosteroid drugs, leading to a remission of the clinical manifestations in some months. When a drug induced bullous disease is probable, it is necessary to interrupt the suspected substance and to start a high dose treatment with corticosteroid drugs to resolve the clinical case in a short period of time.

Abstract
Cutaneous adverse drug reactions (ADRs) are among the most frequent adverse reactions in patients receiving drug therapy. They have a broad spectrum of clinical manifestations, are caused by various drugs, and result from different pathophysiological mechanisms. Hence, their diagnosis and management is challenging. Severe cutaneous ADRs comprise a group of diseases with major morbidity and mortality, reaching 30 % mortality rate in cases of Toxic Epidermal Necrolysis. This chapter covers the terminology, epidemiology, pathogenesis and classification of cutaneous ADR, describes the severe cutaneous ADRs and the clinical and laboratory approach to the patient with cutaneous ADR and presents the translation of laboratory-based discoveries on the genetic predisposition and pathogenesis of cutaneous ADRs to clinical management guidelines.

The mechanism of acantholysis in pemphigus vulgaris (PV) is an intriguing argument since several chemical mediators are implicated. We previously reported a central role for IL-1α and TNF-α, both able to regulate complement activation and plasminogen activators. Very little is known about what triggers the disease (drugs, viruses or food). In this study, we evaluate the molecular role of tannins in acantholysis. By HPLC chromatography we measured tannic acid (TA) and gallic acid (GA) in blister fluid of 4 groups of patients divided according to their dietary habits, including a regular diet, a diet rich in tannins, a diet free of tannins, and a group of pemphigus patients. Blister fluid was obtained from patients using a suction blister apparatus. We show that people with a diet rich in tannins have increased tannin metabolites (TA and GA) in the skin in respect to controls (tannin-rich diet: GA = 194.52±2.39 nmol/ml; TA = 348.28±1.4 nmol/ml versus tannin-Mediterranean diet: GA = 15.28±1.63 nmol/ml; TA = 22.81±1.68 nmol/ml). PV patients showed similar values to the Mediterranean diet population (PV patients: GA = 95.8±1.97 nmol/ml; TA = 199.09±4.15 nmol/ml versus Mediterranean diet: GA = 83.53±2.35 nmol/ml; TA = 195.1±2.50 nmol/ml). In an in vitro acantholysis system using TA and PV-IgG we show that TA 0.1 mM in NHEK culture is able to induce acantholysis. This effect was able to amplify the acantholytic action of PV-IgG in vitro. A blocking study using anti IL-1α and anti TNF-α antibodies showed a reduction in TA-induced acantholysis. Taken together, these results suggest that a diet rich in tannins could be a trigger in genetically predisposed patients. If these data are confirmed, a complementary diet poor in tannins may be useful in patients affected by PV.

A retrospective study of antihypertensives in pemphigus: a still unchartered odyssey particularly between thiols, amides and phenols. Arch Med Sci 2015; 11:1021-7.

Abstract
INTRODUCTION Autoimmune pemphigus diseases comprise several entities with serious prognoses, including the pemphigus vulgaris (PV) group and pemphigus foliaceus (PF) group. Antihypertensives are suspected to be one of the factors triggering/sustaining pemphigus. Here, the data of pemphigus patients regarding arterial hypertension (AH) and taking potentially noxious drugs were statistically analyzed in a setting of a Polish university dermatology department. MATERIAL AND METHODS Medical histories of pemphigus patients (40 admissions of 24 female patients - 13 PV, 11 PF; and 102 admissions of 38 male patients - 24 PV, 14 PF), diagnosed at both immunopathological and biochemical-molecular levels, were studied. RESULTS Ten of 16 (62.50%) AH-positive PV patients received known PV triggers/sustainers 11 times (1-3 per patient). Fourteen of 15 (93.33%) AH-positive PF patients received known PF triggers/sustainers 21 times (1-3 per patient). No differences in numbers of patients taking potentially culprit drugs were shown between PV and PF (Fisher's exact test: p = 0.0829; Yates' χ(2) test: p = 0.1048). The most frequently used culprit drugs were ramipril in PV and enalapril in PF. On average, each PV/PF AH-positive patient received 3.161 different antihypertensives in his/her history of admissions (2.155 antihypertensives per admission). CONCLUSIONS Drug triggering should be suspected in every case of newly diagnosed or exacerbated pemphigus, as eliminating possible PV/PF triggers/sustainers may alleviate the clinical symptoms and enable the decrease of dose/range of immunosuppressants regardless of pemphigus form. Eliminating possible drug PV/PF triggers/sustainers may alleviate the clinical symptoms and enable the decrease of dose/range of immunosuppressants regardless of pemphigus form.

Abstract
Pemphigus and pemphigoid are the prototypical immunobullous diseases. Although it has been well established that they are caused by deposition of autoreactive antibodies directed against adherence proteins within the skin, the specific genetic and environmental factors leading to development of these diseases continue to be an area of investigation. Herein, we discuss several of the potential environmental triggers that may induce patients to develop immunobullous diseases including medications, viral infections, UV exposure or other radiation injury and dietary factors. In addition, the potential genetic and immunologic mechanisms contributing to the pathogenesis of pemphigus and pemphigoid will be reviewed. The multifactorial nature of these diseases contributes to their complexity and highlights the importance of a detailed personal and family history when caring for these patients.

Abstract
PURPOSE To describe the clinical characteristics of ocular involvement in patients with pemphigus at an ophthalmological referral center. METHODS A retrospective review was conducted on patients with the immunopathological diagnosis of pemphigus examined between 1 January 2000 and 1 April 2010. Uncorrected distance visual acuity (UDVA), best corrected distance visual acuity (BCVA), ocular symptoms, and ocular surface inflammatory and scarring changes were assessed. RESULTS A total of 15 patients were identified, with a mean age of 68.27 ± 14.35 years, and 80% (n=12) were female. Extraocular involvement was reported in one patient. All of the eyes showed cicatricial changes in the conjunctiva. In all, 6 eyes (20%) were classified as stage I; 12 eyes (40%) as stage II; 10 eyes (33%) as stage III; and 2 eyes (7%) as stage IV. A statistically significant association was found between BCVA and the severity of ocular involvement. The mean BCVA logMAR was 1.66 (20/914), with a range from logMAR 0 (20/20) to logMAR 4 (NLP). Other ocular diseases were found in 8 (53.3%), systemic diseases in 10 (66.7%), and the use of pemphigus-inducing drugs in 10 patients (66.7%). CONCLUSIONS The present report represents the largest series of ocular involvement in pemphigus confirmed by immunopathology. The clinical manifestations varied from conjunctival hyperemia to corneal scarring and perforation. There was a strong association between scarring changes and low BCVA. Ocular and systemic diseases as well as the use of pemphigus-inducing drugs may predispose to ocular cicatricial changes observed in this series.

Abstract
Pemphigus, a prototypical organ-specific human autoimmune disease, may be associated with other immunity-related disorders, viral infections, and different types of tumors. Coexistence with immune diseases is fairly frequent and, for some of them (eg, myasthenia gravis, Basedow's disease, rheumatoid arthritis, or lupus erythematosus), common pathogenic mechanisms can be considered. The association with viral infections (mainly herpesvirus infections) raises the question of whether the virus triggers the outbreak of the disease or simply complicates its clinical course. Neoplastic proliferations coexisting with pemphigus have a different histogenesis and the pathogenic link may vary according to the associated tumor (thymoma, lymphoma, carcinoma, or sarcoma). A subset of pemphigus-neoplasia association is represented by Anhalt's paraneoplastic pemphigus, with peculiar clinical, histologic, and immunologic features characterizing it. Coexistence of pemphigus with Kaposi's sarcoma, albeit not frequent, offers an intriguing speculative interest. The cornerstone of management in pemphigus is the combination of systemic corticosteroids and immunosuppressants. The conventional treatment used in most cases is based on oral administration of deflazacort and azathioprine. In selected cases, mycophenolate mofetil is preferred to azathioprine. Severe forms of pemphigus require intravenous pulse therapy with dexamethasone (or methylprednisolone) and cyclophosphamide. In the recent years, the use of high-dose intravenous immunoglobulin therapy has gained several consents. Rituximab, a monoclonal anti-CD 20 antibody, which affects both the humoral and cell-mediated responses, has proved to give a good clinical response, often paralleled by decrease of pathogenic autoantibodies. The combination with intravenous immunoglobulin offers the double advantage of better clinical results and a reduced incidence of infection. Interventional treatments, such as plasmapheresis and extracorporeal immunoadsorption, are aimed at patients with life-threatening forms of pemphigus and high levels of circulating autoantibodies, a circumstance where the medical therapy alone risks failing. Second-line treatments include gold salts (which we do not favor because of the acantholytic potential inherent in thiol structure) and the association of oral tetracyclines with nicotinamide, which is rather safe. Local treatments, supplementary to the systemic therapy, are aimed at preventing infections and stimulating reepithelialization of eroded areas. Innovative topical treatments are epidermal growth factor, nicotinamide gel, pimecrolimus, and a proteomics-derived desmoglein peptide. Pemphigus patients should be warned against over-indulging in unnecessary drug intake, prolonged exposure to ultraviolet rays, intense emotional stress, and too spiced or too hot foods. Cigarette smoking is not contraindicated in pemphigus patients because of the nicotine anti-acantholytic properties.

Abstract
Abstract
Drugs have often been implicated as the cause of pemphigus. Lisinopril is a drug of the angiotensin-converting enzyme inhibitor class primarily used in the treatment of hypertension, congestive heart failure, heart attacks, and also in preventing renal and retinal complications of diabetes mellitus. Various side-effects have been described in the English medical literature related to lisinopril, but only one case with pemphigus foliaceus as an adverse reaction to lisinopril. To the best of our knowledge, we present the second case of lisinopril-induced pemphigus foliaceus complicated with Kaposi-Juliusberg varicelliform eruption in a patient diabetes mellitus type II.
A 60-year-old man presented with diffuse erythema on the face, trunk and extremities. Disseminated erosions, 2-5 mm in diameter, and umbilicated vesicles were present. Erosions with remnants of the blister roof were partially found on the trunk. Semiannular erosions were present. On the posterior part of the trunk (paravertebral and vertebral) there were inifiltrated, partially grouped, sharply delineated yellowish-reddish plaques, up to 2 cm in diameter. Direct and indirect immunofluorescence test as well as histological analysis revealed a drug-induced pemphigus foliaceus. After treatment of Kaposi-Juliusberg eruption and impetiginization, lisinopril was discontinued. Rapid involution of the skin lesions, was observed. Since, only minor skin lesions still persisted after 6 months of follow-up and treatment, the diagnosis of druginduced pemphigus foliaceus was established.
It usually takes 1 - 6 months for angiotensin-converting enzyme inhibitors to induce pemphigus. All drugs taken by the patient, including homeopathic agents, over-the-counter drugs, and even medications that were discontinued should be taken into consideration. Medical history taking should be repeated in cases where there is no response to therapy.

Abstract
Pemphigus is an autoimmune bullous disease that may be influenced by genetic and exogenous factors. Drugs are a leading cause of pemphigus. There is a need for a thorough history taking so as to find the culprit medication. The diagnosis of drug-induced pemphigus is challenging. Patients have often been exposed to multiple drugs, and some drugs may have a prolonged latency period between exposure and onset of the disease. The in vitro interferon-gamma (IFN-gamma) release from lymphocytes test has been shown to be of diagnostic value in drug-induced skin reactions. Cessation of the offending drug may alleviate the clinical manifestations and reduce the need for medical treatment.

Abstract
A 76-year-old woman presented with a pruritic photodistributed rash and dysphagia. Serum anti-nuclear antibody was positive (titre 1/1280) and skin and muscle biopsies confirmed a diagnosis of dermatomyositis. She was treated with oral prednisolone (5-50 mg/day), mometasone furoate 0.1% ointment and lotion, and tacrolimus 0.03% ointment. Four years later she presented with multiple painful scaly erosions on the face, scalp and trunk. Histopathology and direct and indirect immunofluorescence confirmed a diagnosis of pemphigus vulgaris. Repeated malignancy screens were negative. She was treated with methotrexate (10 mg/week) and prednisolone (50 mg/day slowly tapered to 5 mg/day), with good control of both diseases.

Abstract
Rheumatoid arthritis presents various cutaneous manifestations, either specific or nonspecific skin features, which are induced by the activation of inflammatory cells (neutrophils, lymphocytes, macrophages), vasculopathy, vasculitis, acral deformity, drugs, and so on. These include (1) specific findings, (2) findings due to vascular impairment, (3) findings due to immune dysfunction, (4) characteristic neutrophilic conditions, and (5) miscellaneous conditions. On the other hand, some of the specific manifestations show common histopathological features such as palisading granulomas with necrobiosis. It is important to recognize the common and/or uncommon skin conditions of RA for all clinicians associated with RA therapy.

Abstract
The acronym PEMPHIGUS is suggested to encompass the numerous factors involved in the pathogenesis and course of the disease. In the following review the authors present studies documenting these factors. The acronym can serve as a handy tool to direct the physician's investigation of a case of pemphigus, aiding in its diagnosis and in the prevention of future flare-ups.

Abstract
A case of pemphigus vulgaris (PV), putatively induced by topical application of polymyxin B ear drops, is described. A 3-year-old, female Tosa Inu, presented with acute onset swelling, blistering and ulceration of the pinnae, nostrils, lips and oral mucous membranes. The dog was depressed, febrile and anorexic. For 7 days prior to the onset of the acute ulcerative disease, polymyxin B ear drops had been applied to both ears to treat an ear infection. Skin and mucosal biopsies showed suprabasilar cleft formation and acantholysis, indicative of PV. The polymyxin B ear drops were discontinued and the dog was treated with intravenous fluids, systemic and topical antibacterial therapy, and immunosuppressive therapy comprising prednisone and azathioprine. Complete remission was noted after 2 weeks, and the immunosuppressive therapy was discontinued one month later. No clinical signs of PV recurred over a 1 year follow-up period. As PV does not usually resolve spontaneously, or enter long-term remission, it was considered that the condition was most likely drug induced due to the aural application of polymyxin B.

Abstract
UNLABELLED Toxic epidermal necrolysis (TEN) is an unpredictable, life-threatening drug reaction associated with a 30% mortality. Massive keratinocyte apoptosis is the hallmark of TEN. Cytotoxic T lymphocytes appear to be the main effector cells and there is experimental evidence for involvement of both the Fas-Fas ligand and perforin/granzyme pathways. Optimal treatment for these patients remains to be clarified. Discontinuation of the offending drug and prompt referral to a burn unit are generally agreed upon steps. Beyond that, however, considerable controversy exists. Evidence both pro and con exists for the use of IVIG, systemic corticosteroid, and other measures. There is also evidence suggesting that combination therapies may be of value. All the clinical data, however, is anecdotal or based on observational or retrospective studies. Definitive answers are not yet available. Given the rarity of TEN and the large number of patients required for a study to be statistically meaningful, placebo controlled trials are logistically difficult to accomplish. The absence of an animal model further hampers research into this condition. This article reviews recent data concerning clinical presentation, pathogenesis and treatment of TEN. LEARNING OBJECTIVES At the conclusion of this learning activity, participants should have acquired a more comprehensive knowledge of our current understanding of the classification, clinical presentation, etiology, pathophysiology, prognosis, and treatment of TEN.

Abstract
BACKGROUND The transglutaminase (TG) family consists of eight distinct isoforms. TG types 1, 3 and 5 play a major role in normal skin development, with TG2 also being elevated during dermal wounding. TG1, 3 and 5 are responsible for the cross-linking of keratin precursors and formation of the cornified envelope during keratinocyte differentiation. TG2 may play a role in keratinocyte basement membrane cross-linking. Abnormal TG expression has been demonstrated in Darier disease, Netherton syndrome, psoriasis and lamellar ichthyosis. During a recent investigation of skin contraction in tissue-engineered skin, transglutaminase inhibitors were found to produce hyperproliferation and parakeratosis. OBJECTIVES Accordingly, this study was designed to study the effect of pan-transglutaminase inhibition on morphology of tissue-engineered skin and expression of keratinocyte differentiation and proliferation-associated antigens. METHODS We used a tissue-engineered model of human skin, based on de-epidermized acellular human dermis, seeded with normal keratinocytes and dermal fibroblasts and cultured at an air-liquid interface. The pan-transglutaminase inhibitors putrescine, NTU283 (1-dimethyl,2-[(oxopropyl)thio]imidazolium) and NTU285 (N-benzyloxycarbonyl-l-glutaminyl-6-dimethylsulfonium-5-oxo-l-norleucine) were added to the culture medium. After 28 days, histology and immunohistochemistry for collagen IV, involucrin and cytokeratins 6, 10 and 16 were performed. RESULTS Keratinocyte hyperproliferation and parakeratosis were seen in response to transglutaminase inhibition. Inhibition of transglutaminase also resulted in loss of basement membrane collagen IV. Involucrin and cytokeratins 6 and 16 were confined to the basal layers in control composites but expressed throughout the epidermis in response to transglutaminase inhibition. A distinct band of expression of cytokeratin 10 was seen in the upper stratum granulosum of control composites but only patchy expression was seen after transglutaminase expression. CONCLUSIONS Pan-transglutaminase inhibition inhibits terminal differentiation of keratinocytes, leading to a hyperproliferative epidermis with parakeratosis and enhanced expression of involucrin and cytokeratins 6 and 16. Expression of the differentiation-associated cytokeratin, cytokeratin 10, is reduced. Basement membrane integrity is also lost as a result of transglutaminase inhibition.

Abstract
Pemphigus can be triggered or induced by many insults, such as drugs, infections, viruses and neoplasms. X-ray-induced pemphigus has been recorded only rarely in the literature. We describe the case of a woman with pemphigus vulgaris in remission, who relapsed 1 week after completion of an irradiation course for breast cancer, in the exact location of the radiation. We review the previous 15 cases from the literature and outline the common features of those cases.

Abstract
BACKGROUND Captopril is an angiotensin-converting enzyme inhibitor with sulphydryl groups in its chemical structure. It is commonly used as an antihypertensive drug. The occurrence of pemphigus vulgaris has repeatedly been reported in patients receiving captopril. The capacity of captopril and pemphigus serum to induce acantholysis, in vivo or in vitro, has been demonstrated experimentally. OBJECTIVES To show that captopril and pemphigus serum, acting by a biochemical and immunological mechanism, respectively, trigger apoptosis. METHODS Human keratinocyte cells were treated with 15 mmol L-1 captopril or with pemphigus serum. DNA was extracted and the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labelling method was used to detect apoptosis. RESULTS DNA fragmentation occurred after 72 h of treatment. Increased expression of p53, c-myc and inducible nitric oxide (NO) synthase (iNOS) mRNA were observed by polymerase chain reaction (PCR) in the treated cells compared with the untreated ones. The increase in iNOS gene expression was associated with overproduction of NO. Moreover, the addition of 1 mmol L-1N-monomethyl-L-arginine, a structural analogue of arginine, reduced nitrite levels by about 70% in cells treated with captopril or pemphigus serum. Western blot analysis revealed an overexpression of heat shock protein 70 (hsp70) in cells treated with captopril or pemphigus serum. Finally, total inhibition of the keratinocyte transglutaminase gene was shown by PCR analysis in the same samples, compared with control cells. CONCLUSIONS These data demonstrate the involvement of apoptosis in keratinocytes treated with captopril or pemphigus serum, with induction of the iNOS gene and hsp70 in the cascade of events leading to programmed cell death.

Abstract
Up to 3% of all hospital admissions are due to adverse drug reactions (ADRs), and between 10% and 20% of hospital inpatients develop ADRs. Individual susceptibility to becoming 'sensitized' or allergic to a drug is thought to result from altered metabolic handling of the drug. Reactive intermediate compounds form haptens, bind to proteins and induce immune responses. Depending on whether the immune system generates antibodies or sensitized T cells, different clinical patterns of hypersensitivity may result. At present, both in vivo or in vitro tests to identify the culprit drug or to confirm the presence of hypersensitivity are not widely used because they are either not generally robust or not readily accessible. In vitro tests require the true immunogen/antigen to detect antibodies or sensitized T cells. As the metabolic basis underlying susceptibility to adverse drug reactions is elucidated, the resolution of immunological mechanisms and development of reliable tests will ensue. This will also become of great value for prediction of individuals at risk of becoming sensitized by a particular drug.

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
Four dogs developed cutaneous lesions following the administration of various antibiotics. Histopathology of the lesions was compatible with pemphigus foliaceus, although apoptotic cells suggestive of erythema multiforme were seen in two cases. In two dogs the lesions resolved after 7.5-8.5 months of immune-suppressive treatment. No recurrence was seen during the follow-up period (3 and 4.5 years). The lesions in the other two dogs resolved within 3 weeks to 3 months following discontinuation of the antibiotic. No recurrence of clinical signs occurred during the follow-up period (1 and 4 years, respectively).

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
A 105-year-old woman developed pemphigus foliaceus. She had been on fosinopril, an angiotensin-converting enzyme inhibitor (ACE inhibitor) for 4 years. Anti-intercellular cement substance antibodies were positive with titre > 160. She died during admission of an unrelated illness. A 57-year-old man developed pemphigus vulgaris after 11 months treatment with quinapril. At 14 months after developing pemphigus, this man continues on prednisone and azathioprine. We speculate that these are cases of ACE-inhibitor-related pemphigus and we review ACE-inhibitor-related pemphigus.

Abstract
The distribution patterns of both tissue and keratinocyte transglutaminases (TGase), as well as that of desmoplakin (DP), have been immunohistochemically investigated in human skin cultured in the absence or presence of cystamine and enalapril, two acantholytic agents. In the control samples, tissue TGase is predominantly expressed in lower layers of the epidermis and is located intercellularly. Conversely, in tissues cultured with cystamine or enalapril, a diffuse cytoplasmatic staining was observed. Similarly, DP, detected on the cell membrane in the control, shifts into the cytosol of the keratinocytes following treatment. The distribution pattern of the keratinocyte enzyme in the acantholytic epidermis was identical to that observed in the normal one. Since cystamine and enalapril are TGase inhibitors and DP was shown to act as a TGase substrate in vitro, we suggest that DP and tissue enzyme may participate in cell adhesion at the intraepidermal level.

Abstract
BACKGROUND In earlier papers, we suggested that the aggravation of psoriasis by antimalarial drugs (analogous to hypolipidemic drugs) could be initiated by a break in the epidermal barrier. We suggested that these drugs exerted their effect by inhibiting epidermal transglutaminase activity, and supported this hypothesis by demonstrating the effect of hydroxychloroquine sulfate (HCQS) on the morphology of cultured skin and on liver transglutaminase activity. In the present article, we describe, for the first time, the morphologic changes induced by HCQS on cultured skin of psoriatic patients. METHODS Uninvolved (apparently normal) skin explanted from the back of two psoriatic patients was cultured in the presence of 9.2 and 13.8 mM of HCQS for 3 days. The morphologic changes were evaluated in a blind manner. The experiment was repeated twice. RESULTS Significant changes in the epidermal morphology of psoriatic skin cultured in the presence of HCQS, compared with skin cultured without the presence of the drug, were observed. The most striking changes were enhanced and irregular keratinization and dermo-epidermal detachment and cleft formation. No parakeratosis or other characteristics of psoriasis were observed. CONCLUSIONS The first changes caused by HCQS on the cultured skin of psoriatic patients are not characteristic of psoriasis, and include hyperproliferation and enhanced and irregular keratinization. The present experimental study gives further support to the hypothesis that HCQS causes an initial break in the barrier function of the epidermis (probably by inhibiting transglutaminase activity), which is followed by a physiologic response of the epidermis aimed at barrier restoration. This rather nonspecific stimulus to epidermal proliferation is probably sufficient to trigger psoriasis, in vivo, among genetically predisposed patients.

Abstract
BACKGROUND A variety of drugs have been implicated in the onset and exacerbation of pemphigus and bullous pemphigoid. The demonstration of biochemical acantholysis in skin explants to various drugs in the absence of autoantibodies, in which the tested drugs evoke a biochemical reaction that leads to desmosomal function loss, may be a valuable adjunct to patient management by confirming the suspicion of drug-related pemphigus or bullous pemphigoid. OBJECTIVE To determine whether a skin explant model might serve as a possible in vitro correlate of drug-induced pemphigus and pemphigoid-like effects related to the calcium channel blocker nifedipine. METHODS Normal human breast skin obtained from nonpemphigus and nonpemphigoid patients undergoing mastectomy was cultured with nifedipine at final concentrations of 2, 4, and 8 mM. The drug effect on skin explants evidenced by morphologic changes was evaluated by microscopy by three observers. RESULTS Five out of seven explants cultured with nifedipine at concentrations ranging from 2 to 8 mM exhibited obvious morphologic changes of two types: intraepithelial (or pemphigus-type) splittings and subepithelial (or pemphigoid-type) splittings. Two explants showed no acantholysis and no subepithelial splittings. Control cultures without polyethylene glycol 200 (PEG) showed no changes. Skin control samples cultured in medium supplemented with 10% PEG displayed vacuolar degeneration throughout the entire epidermis, but no sign of cell-cell dyshesion or dermo-epidermal detachment. CONCLUSIONS A type of skin susceptibility to nifedipine may be genetically determined, with some nifedipine-treated patients developing an acantholytic reaction and others a subepidermal bullous eruption.
