Abstract
Systemic sclerosis (SSc) is a rare connective tissue disorder characterized by immune dysregulation evoking the pathophysiological triad of inflammation, fibrosis and vasculopathy. In SSc, several alterations in the B-cell compartment have been described, leading to polyclonal B-cell hyperreactivity, hypergammaglobulinemia and autoantibody production. Autoreactive B cells and autoantibodies promote and maintain pathologic mechanisms. In addition, autoantibodies in SSc are important biomarkers for predicting clinical phenotype and disease progression. Autoreactive B cells and autoantibodies represent potentially promising targets for therapeutic approaches including B-cell-targeting therapies, as well as strategies for unselective and selective removal of autoantibodies. In this review, we present mechanisms of the innate immune system leading to the generation of autoantibodies, alterations of the B-cell compartment in SSc, autoantibodies as biomarkers and autoantibody-mediated pathologies in SSc as well as potential therapeutic approaches to target these.

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.

The use of high-dose immunoglobulin M-enriched human immunoglobulin in dogs with immune-mediated hemolytic anemia. J Vet Intern Med 2022; 36:78-85.

Abstract
BACKGROUND The IV use of human immunoglobulin (hIVIG) in dogs with primary immune-mediated hemolytic anemia (IMHA) has been described previously, but herein we describe the use of high-dose IgM-enriched hIVIG (Pentaglobin). HYPOTHESIS/OBJECTIVES Dogs treated with high-dose Pentaglobin will experience shorter time to remission and hospital discharge and have decreased transfusion requirements compared to dogs receiving standard treatment alone. ANIMALS Fourteen client-owned dogs diagnosed with primary IMHA at specialist referral hospitals in the United Kingdom. METHODS All prospectively enrolled dogs received prednisolone, dexamethasone or both along with clopidogrel. Patients were randomized to receive Pentaglobin at 1 g/kg on up to 2 occasions, or to serve as controls. No additional immunosuppressive drugs were allowed within the first 7 days of treatment. Remission was defined as stable PCV for 24 hours followed by an increase in PCV. RESULTS Ten of 11 dogs from the treatment group and 2 of 3 dogs from the control group achieved remission and survived until hospital discharge. Survival and time to remission were not significantly different between groups. The volume of packed red blood cells transfused, normalized for body weight, was not significantly different between groups. Potential adverse reactions to Pentaglobin occurred in 2 dogs, but their clinical signs may have been related to the underlying disease. CONCLUSIONS AND CLINICAL IMPORTANCE Treatment with high-dose Pentaglobin was well tolerated by dogs with primary IMHA but no significant advantage was found in this small study. Additional studies examining larger groups and subpopulations of dogs with primary IMHA associated with a poorer prognosis are warranted.

Abstract
Pemphigoid gestationis (PG) is a rare autoimmune bullous skin disorder which usually presents with intense pruritus and urticarial lesions that may evolve into vesicles and tense blisters. In majority of patients, it starts in the second or third trimester of pregnancy and resolves spontaneously after delivery. Lesions appear in the periumbilical area in 90% of patients and rapidly spread centrifugally to other parts of the body. The diagnosis needs to be confirmed by direct immunofluorescence test (DIF) with indirect immunofluorescence test (IIF), ELISA and immunoblot techniques playing role in diagnosis and/or monitoring antibodies level. Mild symptoms of PG can be treated with topical therapy only, but in severe course of the disease the treatment may be escalated to oral corticosteroids. We present an unusual case of PG started 2 weeks after delivery with an updated overview on the epidemiology, pathology, clinical picture, treatment, and complications of the disease.

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
The pemphigoid group is a category of autoimmune subepidermal blistering diseases in which autoantibodies deposit linearly at the epidermal basement membrane zone (BMZ). The main subtypes of pemphigoid mediated by immunoglobulin G autoantibodies are bullous pemphigoid (BP), mucous membrane pemphigoid (MMP) and epidermolysis bullosa acquisita (EBA). To establish the first guidelines approved by the Japanese Dermatological Association for the management of pemphigoid diseases, the Committee for Guidelines for the Management of Pemphigoid Diseases (Including EBA) was founded as part of the Study Group for Rare Intractable Skin Diseases under the Ministry of Health, Labor and Welfare Research Project on Overcoming Intractable Diseases. These guidelines aim to provide current information for the management of BP, MMP and EBA in Japan. Based on evidence, the guidelines summarize the clinical and immunological manifestations, pathophysiologies, diagnostic criteria, disease severity determination criteria, treatment algorithms and treatment recommendations. Because of the rarity of these diseases, there are few clinical studies with a high degree of evidence, so several parts of these guidelines were established based on the opinions of the Committee. To further optimize these guidelines, periodic revision in line with the new evidence is necessary.

Abstract
Autoimmune bullous dermatoses (AIBDs) are a group of rare chronic inflammatory skin diseases, which clinically manifest as blisters and erosions of the skin and/or mucosa. Immunologically, AIBDs are characterized and caused by autoantibodies targeting adhesion molecules in the skin and mucosa. According to the histological location of the blistering, AIBDs are classified into the following two main subtypes: pemphigus (intraepidermal blistering) and pemphigoid (subepidermal blistering). Most AIBDs were potentially life-threatening diseases before the advent of immunosuppressive drugs, especially systemic steroid therapies, which suppress pathogenic immunological activity. Although there have been recent advancements in the understanding of the pathogenesis of AIBDs, glucocorticosteroids and/or adjuvant immunosuppressive drugs are still needed to control disease activity. However, the long-term use of systemic immunosuppression is associated with major adverse events, including death. Based on the growing understanding of AIBD pathogenesis, novel treatment targets have emerged, some of which are currently being evaluated in clinical trials. Within this article, we review the current clinical trials involving pemphigus and pemphigoid and discuss the rationale that lead to these trials. Overall, we aim to foster insights into translational research in AIBDs to improve patient care.

Abstract
Bullous pemphigoid (BP) mainly targets type XVII collagen (COL17). Intravenous immunoglobulin (IVIg) is used to treat numerous autoimmune diseases, including BP. The major mechanism of action for IVIG is thought to be its immunomodulatory effect. However, little is known about the precise mechanisms of IVIg in BP. We investigate the cellular effects of IVIg, toward treatments for BP. Keratinocytes were treated with IgG from BP patients (BP-IgG) and with IVIg, and then the COL17 expression was detected by Western blotting. Cell adhesion and ex vivo dermal-epidermal separation were also investigated for the condition with BP-IgG and IVIg. BP-IgG targeting the non-collagenous 16A domain induces the depletion of COL17 in cultured keratinocytes (DJM-1 cells). The COL17 levels in DJM-1 cells were decreased by 50% after 4 h of BP-IgG stimulation as determined by Western blotting. By contrast, BP-IgG with IVIg was found to result in 70-90% increases in COL17 and to restore adhesion to the plate. Interestingly, IVIg significantly inhibited the binding of BP-IgG to the COL17-enzyme-linked immunosorbent assay plate, and this was due to anti-idiotypic antibodies against BP-IgG. When anti-idiotypic antibodies against BP-IgG in 0.02% of IVIg were depleted from IVIg, those antibodies did not exhibit inhibitory effects on COL17 depletion. When cryosections of human skin were incubated with BP-IgG in the presence of leukocytes, dermal-epidermal separation was observed. BP-IgG treatment with IVIg or anti-idiotypic antibodies did not induce such separation. These findings strongly suggest the presence of anti-idiotypic antibodies against anti-COL17 IgG in IVIg. This mechanism of IVIg could be a target for therapies against BP.

Abstract
Pemphigus is a group of immune-mediated bullous disorders, which often cause fragile blisters and extensive lesions of the skin or mucous membranes, such as in the mouth. This disease could be life-threatening in some cases. During pregnancy, its condition will become more complicated due to the change in the mother’s hormone level and the effect of drug therapy on both the mother and her fetus. Thus, it will be more difficult to identify the clinical manifestations and to establish the treatment plan. In this article, we present a comprehensive review of pemphigus and pregnancy by analyzing 47 cases of pemphigus reported between 1966 and 2014, with diagnosis before or during pregnancy. The aim of this study is to make a comprehensive review of pemphigus and pregnancy, provide organized and reliable information for obstetricians, dermatologists, physicians, and oral medicine specialists.

Abstract
Immunoglobulin G (IgG) has been shown to protect graft rejection after transplantation, whereas the molecular mechanism of IgG in promoting graft acceptance has not been well established. In this study, we tested the effectiveness of IgG in preventing rejection of transplanted skin graft in an immunologically potent rat model, and studied the mechanism of this protection. We found that systemic or local administration of IgG significantly prolonged the survival of skin grafts with the immune tolerance induced by IgG and subcutaneous local injection of 1mg IgG to adult SD rat yielded the longest survival of skin grafts from 5.8 to 17.3 days. We also found that IgG reduced the number of pro-inflammatory cells especially lymphocytes, neutrophils and basophils, increased the seral levels of anti-inflammatory factors including IL-10 and IL-4, and activated CD4+CD25+Foxp3+ regulatory T cells, unveiling the mechanisms of this protective effect. These findings provide new insight to support clinical application of IgG in treating transplantation.

Abstract
Autoimmune bullous diseases (ABDs) are organ-specific autoimmune diseases, in which blisters on the skin and mucous membranes develop through binding of pathogenic autoantibodies to target antigens. There are two major ABD groups: the pemphigus group, showing autoantibodies to desmosomal components; and the subepidermal ABD group, showing autoantibodies to hemidesmosomal components in the epidermal basement membrane zone. Recent immunological, biochemical and molecular biological studies revealed many new autoantigens, including desmocollins, various plakin family proteins and integrins. A revised ABD classification includes new disease entities such as paraneoplastic pemphigus, IgA pemphigus and anti-laminin γ1 pemphigoid. In addition to systemic corticosteroids and various immunosuppressive agents, various adjuvant therapies for ABDs have developed. Among them, intravenous immunoglobulin (IVIG) is a promising therapy, although the therapeutic mechanisms are still unknown. Various disease models for ABDs have developed, particularly for pemphigus vulgaris, bullous pemphigoid and epidermolysis bullosa acquisita (EBA), and these have provided insights into the pathogenesis of various ADBs that suggest possible new treatment strategies. However, the fundamental mechanisms in disruption of immune-tolerance are still unknown. EBA shows autoimmunity to type VII collagen, the major component of anchoring fibrils, and EBA pathogenesis has been studied in various disease models. Previous studies suggested that, following binding of autoantibodies to type VII collagen, activation of complement, cytokine release, neutrophil migration, Fcγ receptors (FcgRs) and metalloproteinases play important roles in induction of subepidermal blisters. In this issue of the Journal of Pathology, Kasperkiewicz and colleagues reveal important roles of activating FcgRIV and inhibitory FcgRIIB in EBA pathogenesis that were recognized by conducting elegant studies using both genetic analysis and functional animal model methods. The expression equilibrium of the activating and inhibitory FcgRs can be modulated towards the inhibitory FcgRIIB by IVIG therapy, resulting in beneficial clinical effects of IVIG in EBA and other autoimmune skin-blistering diseases.

Abstract
We report a case of linear immunoglobulin A bullous disease in a 9-year-old boy who presented with rapidly progressive severe disease and could not tolerate dapsone because of high liver enzymes within a week after a low dose of dapsone in association with an underlying fatty liver. He showed remarkable improvement with intravenous immunoglobulins used as monotherapy, with a rapid clearance and a sustained remission after stopping the treatment.

Abstract
High-dose intravenous immunoglobulin (IVIg) is being increasingly utilized as an off-label therapy for a variety of autoimmune and inflammatory conditions across various specialties. Numerous reports have shown that it is an effective treatment for autoimmune skin blistering disorders. Unlike most therapies for blistering disorders, IVIg is not immunosuppressive and has a favorable side effect profile. This has allowed its use to expand dramatically over the last decade. However, due to the rarity and severity of autoimmune skin blistering diseases, well-designed prospective trials are generally lacking. This work highlights major research developments and the best evidence to date regarding the treatment of autoimmune pemphigus, bullous pemphigoid, mucous membrane pemphigoid, epidermolysis bullosa acquisita, pemphigoid gestationis, and linear IgA dermatosis with IVIg, providing an update on its efficacy, proposed mechanisms of action, side effect profile, and indications for use.

Abstract
A 39-year-old woman in the 39th week of her fifth pregnancy presented with severe itching. In recent weeks she had developed an increasingly itchy rash on her trunk and arms. Upon examination we observed multiple erythematous plaques and vesicles. Histological examinations of two skin biopsies confirmed the diagnosis of pemphigoid gestationis. Because the patient's complaints worsened we decided to deliver the baby, and as it was in transverse lie this was by caesarean section. A healthy son without rash was born. Although pemphigoid gestationis occurs in only 1 in 50,000 pregnancies, it is very important to be aware of this condition when a pregnant woman has itching. Not recognising pemphigoid gestationis may lead to inadequate maternal treatment and possible preterm birth and neonatal pemphigoid gestationis.

Abstract
Background: Pemphigoid gestationis is an autoimmune blistering disease affecting pregnant women. Treatment often consists of topical corticosteroids, oral antihistamines, and oral prednisone followed by immunosuppressants. Refractory cases in antepartum patients present a particular therapeutic challenge as the majority of second-line agents are contraindicated until the patient has delivered. Objective: The following report describes the case of a 34-year-old woman pregnant for the third time at 16 weeks' gestation. Her previous two pregnancies were complicated by pemphigoid gestationis but were successfully managed with oral prednisone and topical agents. During her third pregnancy, the initial lesions were controlled with oral prednisone, but attempts to decrease her dose resulted in disease flare. Conclusion: Monthly infusions of intravenous immunoglobulin (40 g intravenously for 3 consecutive days for 120 g total) proved to be successful in reducing the dose of oral prednisone required to maintain disease remission. A healthy baby was delivered at 37.5 weeks.

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

Abstract
BACKGROUND A range of interventions have been described for treatment of pemphigus, however the optimal therapeutic strategy has not been established. OBJECTIVES To assess the efficacy and safety of all interventions used in the management of pemphigus vulgaris and pemphigus foliaceus. SEARCH STRATEGY We searched the Cochrane Skin Group Specialised Register (October 2008), The Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 4, 2008), MEDLINE (2003 to October 2008), EMBASE (2005 to October 2008), LILACS (1981 to October 2008), Ongoing Trials Registers, reference lists of articles, conference proceedings from international pemphigus meetings and contacted experts in the field. SELECTION CRITERIA Randomised controlled trials of any intervention in pemphigus vulgaris or pemphigus foliaceus. DATA COLLECTION AND ANALYSIS Two authors independently assessed quality and extracted data from studies. All investigators were contacted for further information. Adverse events were identified from included studies. MAIN RESULTS Eleven studies with a total of 404 participants (337 pemphigus vulgaris, 27 pemphigus foliaceus and 40 not specified ) were identified. The quality of included studies was not high, the majority of studies did not report allocation concealment, and power was limited by very small sample sizes. Interventions assessed included prednisolone dose regimen, pulsed dexamethasone, azathioprine, cyclophosphamide, cyclosporine, dapsone, mycophenolate, plasma exchange, topical epidermal growth factor and traditional Chinese medicine. Ten studies included participants with newly diagnosed or newly active recurrent disease, and one trial included participants in maintenance phase.There was sufficient data for 4 meta-analyses, each pooling results of two studies only. For the majority of interventions, results were inconclusive. We found some interventions to be superior for certain outcomes, although we were unable to conclude which treatments are superior overall. Mycophenolate was more effective in achieving disease control than azathioprine (1 study; n=40; RR 0.72; 95% CI 0.52 to 0.99, NNT 3.7). There was evidence of a steroid-sparing benefit of azathioprine (1 study; n=57; MWD -3919 mg prednisolone; 95% CI -6712 to -1126) and cyclophosphamide (1 study; n=54; MWD -3355 mg prednisolone; 95% CI -6144 to -566) compared to glucocorticoids alone. Topical epidermal growth factor decreased time to control (1 study; n=20; HR 2.35; 95% CI 1.62 to 3.41). AUTHORS' CONCLUSIONS There is inadequate information available at present to ascertain the optimal therapy for pemphigus vulgaris or pemphigus foliaceus. Further research is required, especially to assess the optimal glucocorticoid dose, the role of adjuvant immunosuppressive medications, and long-term adverse events to improve harm:benefit analyses.

Abstract
Subepithelial vesiculobullous conditions are chronic autoimmune disorders that arise from reactions directed against components of the hemidesmosomes or basement membrane zones (BMZ) of stratified squamous epithelium to which the term immune-mediated subepithelial blistering diseases (IMSEBD) has been given. Mucous membrane pemphigoid (MMP) is the most common, but variants do exist. Non-immune disorders that involve these epithelial components typically have a genetic basis--the main example being epidermolysis bullosa. All subepithelial vesiculobullous disorders present as blisters and erosions, and diagnosis must be confirmed by biopsy examination with immunostaining, sometimes supplemented by other investigations. No single treatment reliably controls all subepithelial vesiculobullous disorders; the immunological differences within IMSEBD may account for differences in responses to treatment. Currently, as well as improving oral hygiene, immunomodulatory treatment is used to control the oral lesions of MMP, but it is not known if its specific subsets reliably respond to different agents.

Abstract
Autoimmune subepidermal blistering diseases in dogs were all classified as bullous pemphigoid until 1998. Since then, refinements in reagents and immunological techniques have allowed diseases which are histologically similar but which have a different molecular pathogenesis to be described. This report describes the first case of one such disease, epidermolysis bullosa acquisita, to be documented in the UK. The dog presented with a severe blistering and ulcerative disease affecting the oral cavity, pinnae and distal limbs. The diagnosis was confirmed by histopathology and direct and indirect immunofluorescent demonstration of immunoglobulin G reactivity to basement membrane antigens. Treatment with glucocorticoids, azathioprine, colchicine and an intravenous infusion of immunoglobulins resulted in complete resolution. The drugs were discontinued 12 months after the start of treatment and the dog remained in remission.

Abstract
A 3-month-old boy presented with a 2-week history of rapidly spreading skin rashes. Physical examination revealed generalized urticarial plaques with tense bullae and small vesicles. Histologic examination and immunofluorescence established the diagnosis of bullous pemphigoid. The disease was resistant to conventional therapies with the combination of corticosteroids, dapsone, and erythromycin. Finally, intravenous immunoglobulin therapy brought about a remarkable improvement. We suggest that intravenous immunoglobulin therapy is a valuable treatment option for intractable bullous pemphigoid in infants as well as in adults.

Abstract
BACKGROUND The mainstay of therapy of autoimmune mucocutaneous blistering diseases has been prolonged high-dose systemic corticosteroids and immunosuppressive agents. Recently, high-dose intravenous immunoglobulin (IVIg) has been employed in selected cases, with excellent results in most of them. OBJECTIVE We sought to evaluate the outcome of the use of IVIg in patients with autoimmune mucocutaneous blistering diseases refractory to conventional therapy or with contraindications for it. METHODS We performed a retrospective analysis of clinical response to monthly cycles of IVIg in 19 patients affected with autoimmune mucocutaneous blistering diseases: 10 patients with pemphigus vulgaris (PV), 2 with pemphigus foliaceus (PF), 4 with mucous membrane pemphigoid (MMP), 2 with epidermolysis bullosa acquisita, and one with linear IgA bullous dermatosis. RESULTS Four (21%) of 19 cases presented a complete response (2 PV, 1 MMP and 1 epidermolysis bullosa acquisita). Five (26%) patients did not respond to the treatment (3 PV, 1 PF, 1 MMP). Ten patients (53%) had a partial response. LIMITATIONS This was a retrospective noncontrolled study with a heterogeneous group of patients. CONCLUSION The effectiveness of IVIg was inferior to that previously reported. This difference could be attributed to the preparations employed, the different severity of the disease, or individual responses in each patient dependent on Fc receptor gamma polymorphisms.

Abstract
BACKGROUND AND OBJECTIVE Intravenous immunoglobulin (IVIg) is a solution of globulins containing antibodies derived from pooled human plasma of donors and used in the treatment of a number of immune deficiencies and autoimmune diseases. However, several investigators have reported biochemical alterations with use of IVIg. The objective of this study was to evaluate the effects of IVIg therapy on selected biochemical and hematologic parameters in patients with autoimmune mucocutaneous blistering diseases (AMBDs). METHODS In this preliminary clinical study, ten patients with AMBDs (seven with pemphigus vulgaris and three with mucous membrane pemphigoid) received 133 cycles of IVIg for a total of 399 infusions. We evaluated the effects of IVIg therapy on serum hemoglobin (Hb), albumin, and electrolyte levels, including sodium (Na+), potassium (K+), chloride (Cl-) and calcium (Ca2+). Values of these parameters were measured 24 hours before, during, and 24 hours and 4 weeks after the 3-day infusion period. RESULTS The observed variations in serum electrolyte levels were physiologically and clinically negligible. Furthermore, 24 hours after the last infusion, mean electrolyte values had spontaneously returned to normal levels without the need for additional supplementation: Na+ 137.59+/-1.42 mmol/L (p=0.6091 vs baseline); K+ 3.97+/-0.5 mmol/L (p=0.2689); Cl- 103.4+/-2.69 mmol/L (p=0.0388); and Ca2+ 9.07+/-0.44 mg/dL (p=0.5332). Conversely, significant variations in mean Hb and albumin levels were observed. When measured 24 hours after the last infusion, mild/moderate decreases in Hb (11.62+/-2.12 g/dL; p=0.009 vs baseline) and/or albumin (mean 3.14+/-0.24 g/dL; p=0.0016 vs baseline) were evident. Such changes may, albeit very rarely, be of sufficient clinical significance in individual patients as to necessitate additional treatment. CONCLUSION In patients receiving intravenous IVIg for AMBDs, electrolyte values should be monitored but do not represent a real clinical threat. Hemoglobin and albumin values may be altered sufficiently to require additional treatment but this is a very rare occurrence. These findings confirm and extend previous reports of the safety of IVIg therapy.

Abstract
Epidermolysis bullosa acquisita (EBA) is a chronic, subepidermal blistering disease characterized by the presence of autoantibodies to type VII collagen, located below the lamina densa of the basement membrane zone (BMZ). There is a large clinical and histological overlap between EBA and other subepidermal autoimmune bullous diseases, therefore, complex immunological techniques are required to make an accurate diagnosis. Therapy of EBA is also a difficult issue. Most patients do not respond to several common immunosuppressive agents. We describe a patient who has shown a good response to high-dose intravenous immunoglobulin therapy.

Abstract
Atopic dermatitis is a common inflammatory skin condition with increasing incidence in recent decades. The mainstay of treatment has been the combination of emollients and topical corticosteroids, with the addition of systemic therapies in severe cases. New drugs such as the topical calcineurin inhibitors have shown promise in treating mild-to-severe atopic dermatitis. Other novel therapies that have been reported in the literature include leukotriene antagonists, monoclonal antibodies such as infliximab, leflunomide, recombinant interferon gamma and intravenous immunoglobulin. This review will focus on the treatment of adult atopic dermatitis.

Abstract
BACKGROUND High-dose intravenous immunoglobulin (IVIg) has become a part of the treatment armentarium in pemphigus vulgaris (PV). Some consider IVIg as an adjuvant steroid sparing agent in PV, while others as disease modifying that can be used as monotherapy. METHODS We report our experience with a series of 12 PV patients with severe disease treated with IVIg as an adjuvant therapy. RESULTS Ten of 12 patients (83%) showed response to six cycles of IVIg, six (50%) having complete remission and four (33%) having a partial response. This response rate is concordant with previous reports. The therapy was well tolerated. In all 12 patients, treatment with IVIg allowed a gradual reduction of prednisone dose compared with baseline levels. CONCLUSION IVIg treatment was beneficial as a steroid sparing agent in our series of patients with severe PV.

Abstract
BACKGROUND Pemphigoid (herpes) gestationis is a rare blistering disease of pregnancy. Topical and systemic corticosteroids and antihistamines are usually sufficient for treatment. CASE REPORT A patient suffering from severe, therapy-resistant pemphigoid gestationis was successfully treated with the additional use of six sessions of immunoapheresis. Systemic corticosteroids could be tapered and serum autoantibody levels to bullous pemphigoid antigen 2 (BPAG2 = BP180) significantly dropped during this treatment. CONCLUSION Immunoapheresis represents a helpful therapeutic option with few side effects for severe cases of pemphigoid gestationis, unresponsive to conventional treatment.

Abstract
Numerous mechanisms of action have been proposed for intravenous Ig (IVIG). In this study, we used IgG passive transfer murine models of bullous pemphigoid (BP), pemphigus foliaceus (PF), and pemphigus vulgaris (PV) to test the hypothesis that the effect of IVIG in autoantibody-mediated cutaneous bullous diseases is to accelerate the degradation of pathogenic IgG by saturation of the MHC-like Fc receptor neonatal Fc receptor (FcRn). BP, PF, and PV are organ-specific antibody-mediated diseases in which autoantibodies target the hemidesmosomal antigen BP180 and desmosomal antigens Dsg1 and Dsg3, respectively. Antibodies against BP180, Dsg1, and Dsg3, when injected into neonatal mice, induce the BP, PF, and PV disease phenotypes, respectively. We found that FcRn-deficient mice were resistant to experimental BP, PF, and PV. Circulating levels of pathogenic IgG in FcRn-deficient mice were significantly reduced compared with those in WT mice. Administration of high-dose human IgG (HDIG) to WT mice also drastically reduced circulating pathogenic IgG levels and prevented blistering. In FcRn-deficient mice, no additional protective effect with HDIG was realized. These data demonstrate that the therapeutic efficacy of HDIG treatment in the pemphigus and pemphigoid models is dependent on FcRn. Thus, FcRn is a promising therapeutic target for treating such IgG-mediated autoimmune diseases.

Abstract
Pemphigus is an infrequent, organ-specific, autoimmune bullous disease, which affects the skin, mucous membranes and appendages. Histopathologically, it is characterized by acantholysis. Pemphigus has classically been divided into two major groups, pemphigus vulgaris and pemphigus foliaceus, with their respective clinical variants pemphigus vegetans and pemphigus erythematosus. In recent years, new variants of pemphigus have been described: paraneoplastic pemphigus, IgA pemphigus and pemphigus herpetiformis. This article reviews the epidemiology, etiopathogenesis, clinical symptoms, diagnosis, treatment and prognosis of pemphigus. Advances in molecular biology techniques have made it possible to more precisely identify the different antigens against which antibodies are directed, and to fine-tune ELISA diagnostic techniques. Treating pemphigus vulgaris and foliaceus with general steroids has modified their prognosis; it is estimated that mortality in recent decades is less than 10 %. Managing the clinical complications that appear during the evolution of the pemphigus has contributed to reducing morbidity and mortality.

Abstract
Mucous membrane pemphigoid (MMP) is a sub-epithelial vesiculobullous disorder. It is now quite evident that a number of sub-epithelial vesiculobullous disorders may produce similar clinical pictures, and also that a range of variants of MMP exist, with antibodies directed against various hemidesmosomal components or components of the epithelial basement membrane. The term immune-mediated sub-epithelial blistering diseases (IMSEBD) has therefore been used. Immunological differences may account for the significant differences in their clinical presentation and responses to therapy, but unfortunately data on this are few. The diagnosis and management of IMSEBD on clinical grounds alone is impossible and a full history, general, and oral examination, and biopsy with immunostaining are now invariably required, sometimes supplemented with other investigations. No single treatment regimen reliably controls all these disorders, and it is not known if the specific subsets of MMP will respond to different drugs. Currently, apart from improving oral hygiene, immunomodulatory-especially immunosuppressive-therapy is typically used to control oral lesions. The present paper reviews pemphigoid, describing the present understanding of this fascinating clinical phenotype, summarising the increasing number of subsets with sometimes-different natural histories and immunological features, and outlining current clinical practice.

Abstract
INTRODUCTION The interest of intravenous immunoglobulins (Igi.v.) in the treatment of pemphigus is discussed. Pemphigus is not a recognized indication for this treatment by the CEDIT (French Committee for the assessment and diffusion of technological innovations). The aim of this study was to assess the efficacy of Igi.v. in the treatment of severe corticosteroid-dependent or resistant pemphigus. MATERIAL AND METHODS A retrospective study using a standardized questionnaire was conducted in the various departments of dermatology among the "Groupe Bulles" of the French Society of Dermatology. The study collected the following information from 12 patients suffering from pemphigus and treated with Igi.v.: 1) general demographical data; 2) characteristics of the pemphigus; 3) different treatments applied, and 4) efficacy and side effects of treatments. RESULTS Among the 12 patients studied at the end of treatment with Igi.v., 8 were in complete remission (1 fleetingly for 2 months and 1 preceding initiation of Igi.v.), and 2 were improved (1 temporarily for 4 months). A reduction in corticosteroid therapy was possible in 75 p. 100 of cases (9 patients). During treatment with Igi.v., immunosuppressors were combined with oral corticosteroids in 3 cases. It was possible to reduce their dose 1 one case and to stop them in another case. No major side effect related to treatment with Igi.v. was observed. Six months and one year after the treatment, complete remission rates were respectively 6/10 and 5/8. One patient relapsed more than one year after the end of Igi.v. treatment. CONCLUSIONS Although very expensive, treatment with Igi.v. appears of interest in the treatment of severe corticosteroid-dependent or resistant pemphigus. Moreover tolerance is excellent. The results of our study warrant confirmation in a prospective study.

Abstract
Linear IgA dermatosis (LAD) is a well-recognized acquired subepidermal bullous autoimmune disease. LAD is characterized by clinical, histopathological and immunopathological findings. We report the case of a 38-year-old man who suffered from a chronic myeloic leukaemia. Although he received immunosuppressive therapy he developed LAD after an allogenic bone marrow transplantation. After diagnosis of LAD was established we started a successful systemic therapy with dapsone, while continuing the preliminary medication. Here we report for the first time on a possible relationship between LAD and bone marrow transplantation in an immunosuppressed patient.

Abstract
Linear IgA dermatosis is a rare autoimmune bullous skin disease with subepidermal blister formation and linear IgA deposits along the basement membrane zone. We describe two female patients showing erythematous annular plaques with scaling at the margin, strictly localized to the palms in one patient, and also found on the soles and buttocks in the second patient. Histology showed numerous neutrophils in the dermis with an admixture of eosinophils, some subepidermal clefting, and occasional papillary microabscesses. Direct immunofluorescence and immunoelectron microscopy revealed in vivo IgA deposition along the basement membrane zone. One patient cleared after treatment with dapsone. The second patient did not respond to dapsone alone and various immunosuppressive treatment regimens. Considerable improvement was achieved with intravenous immunoglobulin therapy combined with corticosteroid and dapsone.

Abstract
In 1953, Lever differentiated bullous pemphigoid from autoimmune pemphigus. The natural course of bullous pemphigoid is relatively benign, with a disease-related mortality rate of 24% compared with around 70% in pemphigus. In spite of the introduction of systemic corticosteroids, the mortality rates in bullous pemphigoid have generally not improved and vary between 0% and 40%. Higher doses of systemic corticosteroids seem to be associated with higher mortality rates, which led to the addition of corticosteroid-sparing agents to the treatment of bullous pemphigoid. However, many of these modalities are also accompanied by severe adverse effects and have not led to a significant decrease in the mortality rate. In recent years, there has been a move toward less toxic treatment options for a disease that is usually self-limited. A systematic review of the literature found that treatment with lower doses of systemic corticosteroids and potent topical corticosteroids is effective and accompanied by less serious adverse effects, including death. No benefit of the addition of plasmapheresis or azathioprine to systemic corticosteroids has been shown. The treatment of bullous pemphigoid with tetracyclines and niacinamide (nicotinamide) is effective and accompanied by less serious adverse effects. However, more randomized controlled trials are needed to confirm these results and to determine the best treatment for bullous pemphigoid.

Abstract
BACKGROUND Delayed pressure urticaria (DPU) is difficult to treat. High-dose intravenous immunoglobulin (IVIG) has been found to be effective in treating patients with autoimmune chronic urticaria. OBJECTIVES To report the effect of IVIG on eight patients with severe unremitting DPU. METHODS IVIG was administered at a dose of 2 g kg-1 over 2-3 days on an in-patient basis. The response to treatment was assessed subjectively and recorded as remission, improved or unchanged. An autologous serum skin test (ASST) was performed in seven patients. RESULTS Three of eight patients achieved remission; two after one infusion and one after three infusions. Two patients improved. Three patients remained unchanged; of these, two declined further treatment after two infusions, and one failed to improve after six infusions at monthly intervals. Four of seven patients had positive ASST; three responded to IVIG. Two developed delayed positive ASST; both responded to IVIG. Of three patients with negative ASST, two responded. CONCLUSIONS IVIG induced remission or improved symptoms in five of eight patients with DPU with severe unremitting disease who had failed to respond to other therapies or were controlled only with systemic corticosteroids. Those who responded did so with three or fewer infusions. ASST is not a reliable predictor of response to IVIG.

Abstract
BACKGROUND Bullous pemphigoid (BP) is a subepidermal autoimmune blistering disease, which is characterized by blisters on the skin. Autoantibodies to components of the basement membrane zone are usually observed in the sera of patients with BP. Autoantibodies to the bullous pemphigoid antigens (BP Ag1, 230-kDa desmoplakin protein, and BP Ag2, 180-kDa hemidesmosomal protein) are present in the sera of BP patients. OBJECTIVE The objective of this study was to report the influence of intravenous immunoglobulin (IVIg) therapy on autoantibody titres to BP Ag1 and BP Ag2. METHODS In this prospective study, we measured autoantibody titres to both BP Ag1 and BP Ag2, in 10 patients with severe BP, over a period of 18 consecutive months on each patient, using an immunoblot assay. RESULTS Prior to the initiation of IVIg therapy, the sera of nine patients demonstrated the presence of high autoantibody titres to both BP Ag1 and BP Ag2. One patient had autoantibodies to BP Ag1 only. A statistically significant decline in the autoantibody titres to both BP Ag1 and BP Ag2 was observed after 3 months of receiving the first cycle of IVIg therapy. This gradual decline in autoantibody titres continued until patients were observed to have non-detectable titres to BP Ag1 after 11 months and to BP Ag2 after 10 months of receiving IVIg therapy. Once patients achieved non-detectable titres, these patients were considered to be in a serological remission. This serological remission was sustained for an additional 7 months of observation. CONCLUSION Autoantibody titres to BP Ag1 and BP Ag2 can be used to monitor the serological response to treatment in patients with BP. Patients with severe BP who are treated with IVIg therapy, as described in our protocol, achieve a long-term serological remission.

Abstract
Intravenous immunoglobulin (IVIG) preparations are fractionated from a plasma pool of several thousand donors. IVIG contain immune antibodies and physiologic autoantibodies. Immune antibodies reflect the immunologic experience of the donor population. This fraction of IVIG preparations is useful for replacement therapy and passive immunisation. Natural autoantibodies are able to react with the immune system of the recipient of IVIG and are suggested to help to correct immune deregulation. Immunomodulatory and anti-inflammatory properties are based on multiple mechanisms of action which are described. These mechanisms are effective concomitantly and synergistically at every occasion of use of IVIG in inflammatory and autoimmune disorders.

Abstract
High dose intravenous immunoglobulins (IVIG) are important agents in the treatment of numerous diseases in rheumatology and dermatology. Because the diseases treated with IVIG are rare, their use is mostly not based on controlled randomized trials. Since the high costs of therapy often prohibit the use of IVIG as first line therapy and as there are no guidelines on the use of IVIG in dermatologic diseases, a consensus conference was held in Wiesbaden, Germany, to address these issues. This manuscript documents the expert consensus on the use of IVIG in dermatology and reflects current clinical practice. It should be a guideline for the practitioner for the use of IVIG in dermatologic diseases.
