Intravenous Ig Ameliorates Disease in a Murine Model of Anti-Laminin 332 Mucous Membrane Pemphigoid. J Invest Dermatol 2024:S0022-202X(24)00304-X.

Abstract
Intravenous Ig (IVIg) is used to treat mucous membrane pemphigoid, although its therapeutic effectivity is not sufficiently supported by randomized controlled clinical trials, and its mode of action is only insufficiently understood. We have examined the effect of IVIg in a mouse model of anti-laminin 332 mucous membrane pemphigoid and found that IVIg ameliorates both cutaneous and mucosal inflammatory lesions. Our investigation into the modes of action of IVIg in mucous membrane pemphigoid indicated effective anti-inflammatory mechanisms beyond the enhanced degradation of IgG mediated through inhibition of the FcRn. Our results suggest that IVIg curbs the activation of neutrophils at several levels. This includes a direct, immediate inhibitory effect on neutrophil activation by immune complexes but not C5a, which blunts the release of ROS and leukotriene B4 from neutrophils. IVIg also suppresses the formation of neutrophil extracellular traps in response to calcium ion ionophore. In vivo treatment with IVIg altered the transcriptome of blood leukocytes and bone marrow neutrophils toward less proinflammatory phenotypes. Collectively, our results support the effectivity of IVIg in the treatment of mucous membrane pemphigoid and indicate that effects on neutrophils at multiple levels may significantly contribute to its therapeutic effects.

Abstract
Pemphigus and pemphigoid are two potentially life-threatening groups of autoimmune diseases, characterized by autoantibodies targeting structural components of desmosomes or hemidesmosomes, respectively. Affected patients typically show itchy/painful plaques or blistering skin lesions and/or impairing mucosal blistering and erosions, which may strongly impact their quality of life. Since the milestone work of Walter Lever in 1953, who differentiated these two groups of diseases by histopathological analysis of the level of antibody-mediated skin cleavage, enormous progresses occurred. Achievements made in laboratory diagnostics now allow to identify antigen specific structural proteins of the skin that are targeted by pathogenic autoantibodies. These progresses were accompanied by an increased understanding of the pathogenesis of these diseases thanks to the establishment of animal models reproducing disease and on studies on skin and blood of affected individuals, which have been leading to novel and disease-specific treatments. Yet, given their phenotypical overlap with more common dermatological diseases, correct diagnosis and appropriate treatment are often delayed, in some cases leading to irreversible sequelae, including organ dysfunction (i.e., loss of vision in mucous membrane pemphigoid). Here, we provide a concise overview of the clinical appearance, diagnosis and therapeutic management of pemphigus and pemphigoid diseases.

Abstract
ZusammenfassungPemphigus und Pemphigoid sind seltene Autoimmunkrankheiten der Haut mit potenziell lebensbedrohlichem Verlauf. Autoantikörper gegen epidermale und junktionale Strukturproteine (Desmosomen sowie Hemidesmosomen) führen bei Betroffenen typischerweise zu juckenden, schmerzhaften Plaques oder Blasen an der Haut und/oder Blasenbildung und Erosionen der Schleimhäute mit möglicher Einschränkung der Lebensqualität. Seit der bahnbrechenden Arbeit von Walter Lever im Jahr 1953, dem es gelang, mittels histopathologischer Untersuchung diese beiden Krankheitsgruppen anhand des Musters der Antikörper‐vermittelten Blasenbildung zu differenzieren, wurden enorme Fortschritte im Verständnis der Erkrankungen erzielt. Die Errungenschaften in der Labordiagnostik ermöglichten die Identifikation von Zielstrukturen zur präzisen Unterscheidung verschiedener Varianten der bullösen Autoimmunerkrankungen. Diese Fortschritte gingen dank der Entwicklung von Tiermodellen mit einem besseren Verständnis der Pathogenese einher. Außerdem haben Studien an Haut und Blut betroffener Patienten zu neuen und krankheitsspezifischen Behandlungen geführt. Aufgrund ihrer Seltenheit und der klinischen Ähnlichkeit mit anderen dermatologischen Erkrankungen verzögern sich die korrekte Diagnosestellung und die Einleitung einer entsprechenden Therapie häufig, was in einigen Fällen zu irreversiblen Folgeerscheinungen, einschließlich Funktionsstörungen von Organen (zum Beispiel Verlust des Sehvermögens beim Schleimhautpemphigoid) führt. Wir geben hier einen Überblick über das klinische Erscheinungsbild, den Diagnosealgorithmus und das therapeutische Management von Pemphigus‐ und Pemphigoid‐Erkrankungen.

Abstract
Mucous membrane pemphigoid refers to a heterogeneous group of autoimmune diseases with subepidermal blister formation that can affect all mucous membranes with varying frequencies. This is a rare disease without any geographic or sexual predisposition that is characterized by recurrent inflammation and progressive scarring. The specific diagnostics can be negative in up to 50% of cases. The diagnosis is predominantly made in patients aged 60-80 years. Ophthalmologists play an important role in the care of affected individuals as the conjunctiva is the second most frequent site of involvement. The treatment is often tedious and primarily consists of long-term systemic immunosuppression.

A systematic review on efficacy, safety and treatment durability of intravenous immunoglobulin in autoimmune bullous dermatoses: Special focus on indication and combination therapy. Exp Dermatol 2023. [PMID: 37150538 DOI: 10.1111/exd.14829] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 04/10/2023] [Accepted: 04/23/2023] [Indexed: 05/09/2023]
Abstract
Autoimmune bullous diseases (AIBDs) are a group of rare blistering dermatoses of the mucous membrane and/or skin. The efficacy, safety and treatment durability of intravenous immunoglobulin (IVIg) as an alternative treatment should be explored to systematically review the available literature regarding treatment outcomes with IVIg in AIBD patients. The predefined search strategy was incorporated into the following database, MEDLINE/PubMed, Embase, Scopus and Web of Science on 18 July 2022. Sixty studies were enrolled using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The use of IVIg alone or combined with rituximab was reported in 500 patients with pemphigus, 82 patients with bullous pemphigoid, 146 patients with mucous membranes pemphigoid and 19 patients with epidermolysis bullosa acquisita. Disease remission with IVIg therapy and RTX + IVIg combination therapy were recorded as 82.8% and 86.7% in pemphigus, 88.0% and 100% in bullous pemphigoid and 91.3% and 75.0% in mucous membrane pemphigoid, respectively. In epidermolysis bullosa acquisita, treatment with IVIg led to 78.6% disease remission; no data were available regarding the treatment with RTX + IVIg in this group of patients. Among all the included patients, 37.5% experienced at least one IVIg-related side effect; the most common ones were headaches, fever/chills and nausea/vomiting. The use of IVIg with or without rituximab had a favourable clinical response in patients with AIBDs. IVIg has no major influence on the normal immune system, which makes its utilization for patients with AIBDs reasonable.

Abstract
AIM To provide an epidemiological characterization of ocular cicatricial pemphigoid (OCP) in Colombia. METHODS We conducted a cross-sectional study using SISPRO. We applied the specific code of the International Classification of Diseases for Ocular Pemphigoid, from 2009-2019 to estimate prevalence, incidence, and the demographic status of the disease in Colombia. RESULTS The estimated average prevalence was 0.22 per 1 000 000 inhabitants, and the estimated average incidence was 0.24 per 1 000 000 inhabitants. With a female predominance of 62.5%, and a male/female ratio of 1:1.6. The group of patients diagnosed with the disease after the age of 80 presented the highest prevalence. The departments with the highest prevalence were Antioquia, Bogotá, and Santander. CONCLUSION There are important differences between worldwide and Colombian prevalence and incidence data, which may be related to genetic and epigenetic factors, and the possible underdiagnosis of the disease. According to the results, OCP is an extremely rare disease in Colombia. Nevertheless, it is important to encourage awareness of the disease due to its devastating consequences.

Abstract
Ocular cicatricial pemphigoid (OCP) represents an insidious, autoimmune-mediated disease of the conjunctiva, initially presenting as chronic conjunctivitis and progressing to fibrosis, cicatrization, and eventually blindness secondary to corneal keratinization. This series reports 3 cases presenting with chronic conjunctivitis lasting an average of 10 years without cicatrix formation, ultimately diagnosed as OCP based on direct immunofluorescence of conjunctival biopsy samples. This chronic conjunctivitis without fibrosis suggests the possibility of an OCP subtype with a prolonged early stage or prodrome prior to cicatrization, which may benefit from early diagnosis and treatment to prevent complications of this disease.

Abstract
This guideline has been initiated by the task force Autoimmune Blistering Diseases of the European Academy of Dermatology and Venereology, including physicians from all relevant disciplines and patient organizations. It is a S3 consensus-based guideline that systematically reviewed the literature on mucous membrane pemphigoid (MMP) in the MEDLINE and EMBASE databases until June 2019, with no limitations on language. While the first part of this guideline addressed methodology, as well as epidemiology, terminology, aetiology, clinical presentation and outcome measures in MMP, the second part presents the diagnostics and management of MMP. MMP should be suspected in cases with predominant mucosal lesions. Direct immunofluorescence microscopy to detect tissue-bound IgG, IgA and/or complement C3, combined with serological testing for circulating autoantibodies are recommended. In most patients, serum autoantibodies are present only in low levels and in variable proportions, depending on the clinical sites involved. Circulating autoantibodies are determined by indirect IF assays using tissue substrates, or ELISA using different recombinant forms of the target antigens or immunoblotting using different substrates. The major target antigen in MMP is type XVII collagen (BP180), although in 10-25% of patients laminin 332 is recognized. In 25-30% of MMP patients with anti-laminin 332 reactivity, malignancies have been associated. As first-line treatment of mild/moderate MMP, dapsone, methotrexate or tetracyclines and/or topical corticosteroids are recommended. For severe MMP, dapsone and oral or intravenous cyclophosphamide and/or oral corticosteroids are recommended as first-line regimens. Additional recommendations are given, tailored to treatment of single-site MMP such as oral, ocular, laryngeal, oesophageal and genital MMP, as well as the diagnosis of ocular MMP. Treatment recommendations are limited by the complete lack of high-quality randomized controlled trials.

Abstract
OBJECTIVE Mucous membrane pemphigoid (MMP) is an autoimmune blistering disorder with tendency to scarring. Long term immunosuppressive treatment may be required to minimize the consequences of the disease. METHODS In this retrospective study, we investigated the efficacy of rituximab (RTX) in MMP patients and compare the beneficial effects of early versus late administration of RTX. Medical records of 24 MMP patients who were treated with 500 mg RTX on day 1, then weekly for 4 consecutive weeks were reviewed. RESULTS Twenty-one patients (87.5%) reached disease control (DC) at the mean interval of 4.95 months (SD: 5.15; range: 1-24) after RTX. Complete remission (CR) with scarring was achieved in 45.8% (n = 11) and 33.3% (n = 8) attained CR without any residual scar (total CR with or without scar 79.1%). Two patients (8.3%) reached partial remission including persistent gingivitis. Only one patient progressed from non-cicatricial to cicatricial MMP despite receiving RTX. 47.6% (n = 10) of patients experienced relapse after achieving DC at a mean interval of 15.2 months (range: 6-30, SD: 7.0). Considerably, earlier the RTX was administered, sooner the DC was obtained (Pearson r = 0.742, p-value < .001). CONCLUSIONS These results suggest that RTX may prevent further scarring and progression in MMP patients especially if administered early.

Abstract
BACKGROUND AND OBJECTIVES Treatment of severe dermatological autoimmune diseases and toxic epidermal necrolysis (TEN) with high-dose intravenous immunoglobulin (IVIg) is a well-established procedure in dermatology. As treatment with IVIg is usually considered for rare clinical entities or severe cases, the use of immunoglobulin is not generally based on data from randomized controlled trials usually required for evidence-based medicine. Since the indications for the use of IVIg are rare, it is unlikely that such studies will be available in the foreseeable future. Because first-line use is limited by the high costs of IVIg, the first clinical guidelines on the use of IVIg in dermatological conditions were established in 2008 and renewed in 2011. METHODS The European guidelines presented here were prepared by a panel of experts nominated by the European Dermatology Forum (EDF) and European Academy of Dermatology and Venereology (EADV). The guidelines were developed to update the indications for treatment currently considered effective and to summarize the evidence for the use of IVIg in dermatological autoimmune diseases and TEN. RESULTS AND CONCLUSION The current guidelines represent consensual expert opinions and definitions on the use of IVIg reflecting current published evidence and are intended to serve as a decision-making tool for the use of IVIg in dermatological diseases.

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
Mucous membrane pemphigoid (MMP) is a pemphigoid disease defined by the presence of autoantibodies against the dermal-epidermal junction and predominant involvement of mucous membranes. Diagnosis is made by the clinical presentation and linear deposits of IgG and/or IgA and/or C3 at the dermal-epidermal junction by direct immunofluorescence microscopy of a perilesional biopsy. Circulating autoantibodies can be detected in most patients by indirect immunofluorescence microscopy on salt-split human skin as well as ELISA and immunoblotting with recombinant and cell-derived target antigens. For systemic treatment of MMP, corticosteroids, dapsone, mycophenolates, and azathioprine are applied. In severe cases and in cases with rapid disease progression cyclophosphamide, rituximab, high-dose intravenous immunoglobulins, and immunoadsorption are used. For the successful management of MMP patients, close cooperation with dentists, ophthalmologists, ENT specialists, gynecologists, and gastroenterologists is essential.

Abstract
Mucous membrane pemphigoid (MMP) is a systemic cicatrizing autoimmune disease that primarily affects orificial mucous membranes, such as the conjunctiva, the nasal cavity, the oropharynx, and the genitalia. Ocular involvement occurs in about 70% of all MMP cases. Ocular MMP (OcMMP) also encompasses the conditions linear immunoglobulin A disease, mucosal dominated epidermolysis bullosa acquisita, and anti-laminin 332/anti-epiligrin/anti-laminin 5 pemphigoid. It is a complex clinical entity that may lead to ocular surface failure and result in inflammatory and infectious complications, as well as potentially devastating visual loss. Early diagnosis and appropriate treatment are of paramount importance and require a high level of expertise as this condition can be extremely challenging to diagnose and treat even for experienced clinicians. In this review we provide an up-to-date insight on the pathophysiology of OcMMP, with an emphasis on the current state of its diagnostics and therapeutics. Our the aim is to increase our understanding of OcMMP and highlight modern diagnostic and therapeutic options.

Abstract
Purpose: To evaluate whether long-term remission of ocular cicatricial pemphigoid (OCP) after withdrawal of immunomodulatory therapy (IMT) is possible. Methods: A total of 34 of 464 presenting patients (66 eyes) with biopsy-proven OCP in long-term remission off IMT were identified after finishing a 2-year IMT regimen without active disease (2005-2015). Long-term remission off IMT for OCP was defined as patients withdrawn from IMT ≥1 year lacking clinically detectable progressive scarring according to Foster staging and subjective assessment. Results: All 34 patients achieved ≥1 year of clinical remission without IMT following 2 years IMT lacking active disease. Mean onset age of OCP was 67.0 years, and median follow-up time was 63.4 months. Mean duration between OCP onset and IMT initiation was 29.5 months, with a mean sustained remission time of 36.0 months off IMT. The mean duration of IMT prior to remission off IMT was 34.8 months (median 32 months, IQR 27-39.5 months). Commonly, methotrexate was used prior to OCP remission (19 patients; 55.9%). Two patients experienced mild flare-up postremission off IMT at months 25 and 37 and a course of topical steroid appeared to resolve the inflammation. Another patient had active inflammation at last office visit 5 years after discontinuation of IMT and will restart IMT. Conclusions: Long-term remission for OCP off IMT may be achieved after stepladder IMT is implemented and withdrawn. Longer follow-up and more sensitive measures of scarring and inflammation are needed to generate a consensus on the definition of complete remission and on cessation of systemic IMT for OCP.

Abstract
Intravenous immunoglobulin (IVIG) replacement therapy has been used in immune deficiency diseases for more than 50 years. The indications for this treatment have evolved, however, and IVIG therapy is now used in various diseases in which the immune system plays a prominent role. IVIG therapy has carved out a niche in dermatology for the treatment of such conditions as dermatomyositis, autoimmune bullous diseases, and toxic epidermal necrolysis. Special attention has been paid to this therapy in recent years. New guidelines have been published and should be taken into consideration in dermatology. This review provides a practical guide to IVIG use in our specialty.

Abstract
Autoimmune blistering diseases (AIBD) are a group of chronic diseases affecting the skin and mucous membranes, with different presentation, clinical course, histologic and immunopathologic findings, and different therapeutic approach. Blisters develop as a result of autoantibodies directed against distinct adhesion structures within desmosomes or within the basement membrane zone. The most common AIBD that develops in the elderly is bullous pemphigoid (previously also named "pemphigoid senilis"), but mature patients can also present with other AIBD as mucous membrane pemphigoid, epidermolysis bullosa acquisita, paraneoplastic pemphigus, pemphigus vulgaris, pemphigus foliaceus, linear IgA dermatosis, and dermatitis herpetiformis. There are no differences in treatment approach to mature patients with AIBD, but due to more common comorbidities, systemic therapy should be given with more caution and control, and due to distorted skin integrity in the aged skin, the safety concerns are increased with the long-term use of any topical medication.

Abstract
This review is in two sections. The first section summarises 35 conditions, both common and infrequent, causing cicatrising conjunctivitis. Guidelines for making a diagnosis are given together with the use of diagnostic tests, including direct and indirect immunofluorescence, and their interpretation. The second section evaluates our knowledge of ocular mucous membrane pemphigoid, which is the commonest cause of cicatrizing conjunctivitis in most developed countries. The clinical characteristics, demographics, and clinical signs of the disease are described. This is followed by a review and re-evaluation of the pathogenesis of conjunctival inflammation in mucous membrane pemphigoid (MMP), resulting in a revised hypothesis of the autoimmune mechanisms causing inflammation in ocular MMP. The relationship between inflammation and scarring in MMP conjunctiva is described. Recent research, describing the role of aldehyde dehydrogenase (ALDH) and retinoic acid (RA) in both the initiation and perpetuation of profibrotic activity in MMP conjunctival fibroblasts is summarised and the potential for antifibrotic therapy, using ALDH inhibition, is discussed. The importance of the management of the ocular surface in MMP is briefly summarised. This is followed with the rationale for the use of systemic immunomodulatory therapy, currently the standard of care for patients with active ocular MMP. The evidence for the use of these drugs is summarised and guidelines given for their use. Finally, the areas for research and innovation in the next decade are reviewed including the need for better diagnostics, markers of disease activity, and the potential for biological and topical therapies for both inflammation and scarring.

Abstract
BACKGROUND AND OBJECTIVES Treatment of severe dermatological autoimmune diseases and toxic epidermal necrolysis (TEN) with high-dose intravenous immunoglobulin (IVIg) is a well-established procedure in dermatology. As treatment with IVIg is usually considered for rare clinical entities or severe cases, the use of immunoglobulin is not generally based on data from randomized controlled trials usually required for evidence-based medicine. Since the indications for the use of IVIg are rare, it is unlikely that such studies will be available in the foreseeable future. Because first-line use is limited by the high costs of IVIg, the first clinical guidelines on the use of IVIg in dermatological conditions were established in 2008 and renewed in 2011. METHODS The European guidelines presented here were prepared by a panel of experts nominated by the EDF and EADV. The guidelines were developed to update the indications for treatment currently considered effective and to summarize the evidence for the use of IVIg in dermatological autoimmune diseases and TEN. RESULTS AND CONCLUSION The current guidelines represent consensual expert opinions and definitions on the use of IVIg reflecting current published evidence and are intended to serve as a decision-making tool for the use of IVIg in dermatological diseases.

Abstract
Objective: To determine the efficacy of various intravenous immunoglobulin (IVIG) protocols used in the treatment of autoimmune and chronic inflammatory disorders. Data Sources: Literature retrieval was accessed through MEDLINE (November 1984–March 2007) and a search was conducted using the term intravenous immunoglobulin. References cited in the selected articles were also reviewed. Study Selection and Data Extraction: Inclusion criteria for studies were (1) English language, (2) randomized controlled trials, (3) defined protocols, (4) a minimum of 15 patients, and (5) objective criteria provided to assess clinical outcomes and course. Data Synthesis: The therapeutic efficacy of IVIG therapy is well established, and defined protocols exist for treatment of Kawasaki disease, immune thrombocytopenic purpura, Guillain–Barré syndrome, chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy, and autoimmune mucocutaneous blistering diseases. In the absence of a defined protocol, studies have demonstrated that IVIG therapy is effective in the treatment of myasthenia gravis, dermatomyositis, stiff person syndrome, antineutrophil cytoplasmic antibody positive systemic vasculitides, Graves' ophthalmopathy, and certain forms of systemic lupus erythematosus. It might also be of benefit in some patients with relapsing–remitting multiple sclerosis. The outcomes are variable in these studies. In toxic epidermal necrolysis and Stevens–Johnson syndrome, use of IVIG has dramatically influenced clinical response and reduced mortality. Conclusions: The cumulative evidence suggests that the clinical outcomes observed are significantly influenced by the use of a defined protocol. There is a need for multicenter trials approved by the Food and Drug Administration to better define the role of IVIG in many disease states. Such studies would be able to establish the indications for use, optimal dose, frequency of infusions, duration of therapy, and need for gradual withdrawal versus sudden cessation. Defined protocols resulting from the study of a large cohort of patients often convince insurance companies to create policies that provide access to IVIG therapy.

Abstract
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare, but potentially blinding diseases that affect the skin and mucous membranes. Although the cutaneous manifestations tend to be self-limited and resolve without sequelae, the chronic ocular complications associated with SJS/TEN can persist despite local therapy. Poor understanding of the underlying pathophysiology and lack of a standardized clinical approach have resulted in a paucity of data in regards to suitable treatment options. Inflammatory cellular infiltration and elevated levels of ocular surface cytokines in the conjunctival specimens of affected patients give credence to an underlying immunogenic etiology. Furthermore, the presence of ongoing ocular surface inflammation and progressive conjunctival fibrosis in the absence of exogenous aggravating factors suggest a possible role for systemic immunomodulatory therapy (IMT). We review in detail the proposed immunogenesis underlying chronic ocular SJS/TEN and the possible utility of systemic IMT.

The role of intravenous immunoglobulin in treatment of mucous membrane pemphigoid: A review of literature. JOURNAL OF RESEARCH IN MEDICAL SCIENCES : THE OFFICIAL JOURNAL OF ISFAHAN UNIVERSITY OF MEDICAL SCIENCES 2016; 21:37.

Abstract
BACKGROUND Mucous membrane pemphigoid (MMP) is considered an autoimmune blistering disease that predominantly affects mucous membranes. Various treatments are available for controlling the diseases, but not all of them may respond. MATERIALS AND METHODS PubMed and Google Scholar were searched for all the associated studies until 2015, using the keywords such as "cicatricial pemphigoid" or "ocular pemphigoid" or "mucous membrane pemphigoid" or "MMP" and "intravenous immunoglobulin" or "IVIg" to find all the relevant studies. The last search update was for September 2, 2015. Among the searched items, only English studies were included in the review. RESULTS After excluding nonrelevant studies, 13 studies with a total number of seventy patients with MMP who were under treatment with IVIg were analyzed. The 65 patients responded completely, one did not respond, two had partially responded, and the remaining two patients stopped IVIg therapy, which resulted in ocular cicatricial pemphigoid progression. Majority of the studies reported mild adverse effects while two of them did not report any unwanted side effect. The most common side effect was headache, followed by nausea. Most of the patients who had a cessation of IVIg therapy before achieving clinical remission experienced the disease progression. CONCLUSION Overall, it can be concluded that IVIg therapy was very helpful in treatment of MMP patients who did not respond to conventional therapy or stopped using them for various side effects. Adverse effects associated with IVIg therapy were considerably lower than conventional therapy that can lead toward treatment with this agent in patients who suffer from severe side effects.

Abstract
Pemphigoid diseases are a group of well defined autoimmune disorders that are characterised by autoantibodies against structural proteins of the dermal-epidermal junction and, clinically, by tense blisters and erosions on skin or mucous membranes close to the skin surface. The most common of these diseases is bullous pemphigoid, which mainly affects older people and the reported incidence of which in Europe has more than doubled in the past decade. Prognosis and treatments vary substantially between the different disorders and, since clinical criteria are usually not sufficient, direct immunofluorescence microscopy of a perilesional biopsy specimen or serological tests are needed for exact diagnosis. In eight pemphigoid diseases the target antigens have been identified molecularly, which has allowed the development of standard diagnostic assays for detection of serum autoantibodies-some of which are commercially available. In this Seminar we discuss the clinical range, diagnostic criteria, diagnostic assay systems, and treatment options for this group of diseases.

Abstract
Intravenous immunoglobulin (IVIG) has been shown to be effective in the treatment of autoimmune blistering diseases and may be an option if disease is refractory to conventional treatment. IVIG effectiveness appears to increase when administered concurrently with a cytotoxic drug and used in multiple treatment cycles (though a single cycle may give benefit). Tapering administration may improve the duration of remission and subcutaneous injections may be an option. This article provides an introduction to the make-up and use of IVIG, and reviews previous studies.

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
Mucous membrane pemphigoid (MMP) is an autoimmune blistering disorder that is characterized by subepithelial bullae. Various basement membrane zone components have been identified as targets of autoantibodies in MMP. Considerable variability exists in the clinical presentation of MMP. Mucous membranes that may be involved include the oral cavity, conjunctiva, nasopharynx, larynx, esophagus, genitourinary tract, and anus. A multidisciplinary approach is essential in the management of MMP. Early recognition of this disorder and treatment may decrease disease-related complications. The choice of agents for treatment of MMP is based upon the sites of involvement, clinical severity, and disease progression. For more severe disease, or with rapid progression, systemic corticosteroids are the agents of choice for initial treatment, combined with steroid-sparing agents for long-term maintenance. Due to the rarity of this disease, large controlled studies comparing the efficacy of various agents are lacking.

Abstract
Intravenous immunoglobulin (IVIg) is a biologic agent that is being increasingly used in the treatment of autoimmune and chronic inflammatory disorders. It is approved by the US FDA for the treatment of primary immunodeficiencies, immune thrombocytopenic purpura, Kawasaki disease, bone marrow transplantation in patients aged over 20 years, chronic B-cell lymphocytic leukemia, and pediatric AIDS. IVIg has been used off-label for several diseases, clinical symptoms and syndromes. Our aim was to determine if there is evidence to support the efficacy of IVIg therapy in autoimmune mucocutaneous blistering diseases (AMBDs). We searched the PubMed database for studies on pemphigus and pemphigoid using the following criteria: (i) English language; (ii) minimum of five patients; (iii) diagnosis based on histology and immunopathology; and (iv) statistical analysis of data for comparison of efficacy provided. We evaluated the data and present information on the number of participants in each study, pre-IVIg therapy, indications for the use of IVIg, IVIg protocol (dose and interval) used, concomitant therapies, clinical outcome, follow-up period, and serologic studies. The quality of the evidence presented in this review is at Level A according to the UK National Health Service criteria. Twenty-three studies that were published between May 1999 and April 2010 were identified. One randomized controlled trial was found and all other studies were case series. Data on 260 patients treated with IVIg were analyzed: 191 patients with pemphigus and 69 patients with pemphigoid. Overall, 245 patients showed improvement with IVIg therapy. IVIg demonstrated a corticosteroid-sparing effect. In the studies presented, the incidence of serious adverse effects was not significant. The best available evidence in the literature indicates that IVIg is efficacious and has a good safety profile in the treatment of AMBDs.

Abstract
Intravenous immunoglobulins (IVIg) were first introduced in the middle of the twentieth century for the treatment of primary immunodeficiencies. In 1981, Paul Imbach noticed an improvement of immune-mediated thrombocytopenia, in patients receiving IVIg for immunodeficiencies. This opened a new era for the treatment of autoimmune conditions with IVIg. Since then, IVIg has become an important treatment option in a wide spectrum of diseases, including autoimmune and acute inflammatory conditions, most of them off-label (not included in the US Food and Drug Administration recommendation). A panel of immunologists and internists with experience in IVIg therapy reviewed the medical literature for published data concerning treatment with IVIg. The quality of evidence was assessed, and a summary of the available relevant literature in each disease was given. To our knowledge, this is the first all-inclusive comprehensive review, developed to assist the clinician when considering the use of IVIg in autoimmune diseases, immune deficiencies, and other conditions.

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

Abstract
PURPOSE To describe the clinical and immunopathologic features of patients with 2 different types of paraneoplastic conjunctival cicatrization. DESIGN Retrospective observational case analyses with a review of the literature. PARTICIPANTS One patient with paraneoplastic ocular cicatricial pemphigoid (POCP) and 1 patient with paraneoplastic pemphigus (PNP) with ocular involvement. METHODS Critical review of clinical history, diagnostic studies, and immunopathologic results of biopsies in the 2 cases, together with a review of the literature. MAIN OUTCOME MEASURES Ability to recognize paraneoplastic conjunctival cicatrization and to diagnose the conditions accurately. RESULTS The first patient, 46 years of age, presented with conjunctival scarring and symblephara, cough, oral lesions, and chest rash. Concurrently, a diagnosis of pulmonary squamous cell carcinoma was made. Conjunctival biopsy revealed a subepithelial bulla, an inflammatory infiltrate of T and B lymphocytes, and basement membrane zone deposition of immunoglobulin (Ig)-G and C3 consistent with POCP. The second patient, 54 years of age, had a recently diagnosed B-cell chronic lymphocytic leukemia, followed 1 month later with ocular irritation and bilateral extensive symblephara. Extensive oral lesions and skin involvement of the lower half of the body were seen. Skin biopsy disclosed subepidermal bullae and mostly T cells with virtually no B cells in the dermal infiltrate (the patient was being treated with rituximab). Linear subepithelial deposition of IgG and C3 and deposition within the epidermis were consistent with PNP. Further indirect immunofluorescence and immunoprecipitation studies with the patient's serum-derived antibodies established PNP as the definitive diagnosis. CONCLUSIONS Underlying malignancy is an important consideration in younger patients with puzzling bilateral cicatrizing conjunctivitis, and a paraneoplastic condition can be established from either a conjunctival or a skin biopsy.

Abstract
PURPOSE To evaluate the effectiveness of immunosuppressive drug therapy in the treatment of ocular mucous membrane pemphigoid (MMP). DESIGN Retrospective cohort study. PARTICIPANTS Ninety-four patients with biopsy-proven ocular MMP seen at the Pemphigoid Clinic at Wilmer Eye Institute from July 1984 through November 2006. METHODS Data recorded included demographics, use and doses of immunosuppressive drugs, response to therapy, and side effects associated with drug use. MAIN OUTCOME MEASURES Outcome measures included: (1) ocular control, defined as resolution of inflammation and cessation of cicatrization of the conjunctiva; (2) ocular remission, defined as ocular control for 3 months or more after the cessation of immunosuppressive drug therapy; and (3) ocular relapse, defined as the recurrence of ocular disease in either eye after a remission. RESULTS By 1 year of treatment, 82.9% of patients had complete control of the inflammation, and of these, 86.3% achieved a remission at some point during follow-up. The incidences of ocular control, remission, and relapse were 1.03 (95% confidence interval [CI], 0.78-1.33), 0.50 (95% CI, 0.37-0.67), and 0.04 (95% CI, 0.02-0.09) events per person-years (PY), respectively. Among patients initially treated with prednisone and cyclophosphamide (n = 44), 91% of patients achieved a remission within 2 years after the initiation of immunosuppressive drug therapy. Characteristics at presentation associated with failing to achieve remission in the univariate analysis were trichiasis (relative risk [RR], 0.28; 95% CI, 0.08-097), prior eyelid surgery (RR, 0.11; 95% CI, 0.02-0.78), and esophageal involvement (RR, 0.29; 95% CI, 0.10-0.83). After adjusting for confounding, an initial treatment regimen containing cyclophosphamide and prednisone was associated with a greater likelihood of achieving ocular remission (RR, 8.53; 95% CI, 2.53-28.86; P = 0.001) when compared with other initial treatment regimens. Infections, hematuria, and anemia were the most common side effects observed in patients receiving cyclophosphamide therapy. The rate of discontinuing cyclophosphamide resulting from side effects was 0.20/PY; however, 74% of these patients still achieved remission despite early discontinuation of cyclophosphamide. CONCLUSIONS In patients with ocular MMP, most achieved ocular disease control with immunosuppressive drug therapy. Treatment with cyclophosphamide and prednisone was strongly associated with the development of ocular remission.
