Epidermolysis bullosa acquisita: efficacy of high-dose intravenous immunoglobulins

Current and Innovated Managements for Autoimmune Bullous Skin Disorders: An Overview

Autoimmune bullous skin disorders are a group of disorders characterized by the formation of numerous blisters and erosions on the skin and/or the mucosal membrane, arising from autoantibodies against the intercellular adhesion molecules and the structural proteins. They can be classified into intraepithelial or subepithelial autoimmune bullous dermatoses based on the location of the targeted antigens. These dermatoses are extremely debilitating and fatal in certain cases, depending on the degree of cutaneous and mucosal involvement. Effective treatments should be implemented promptly. Glucocorticoids serve as the first-line approach due to their rapid onset of therapeutic effects and remission of the acute phase. Nonetheless, long-term applications may lead to major adverse effects that outweigh the benefits. Hence, other adjuvant therapies are mandatory to minimize the potential harm and ameliorate the quality of life. Herein, we summarize the current therapeutic strategies and introduce promising therapies for intractable autoimmune bullous diseases.

Japanese guidelines for the management of pemphigoid (including epidermolysis bullosa acquisita)

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.

The use of intravenous immunoglobulin in autoimmune bullous diseases

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.

Epidermolysis bullosa acquisita: autoimmunity to anchoring fibril collagen

Epidermolysis bullosa acquisita (EBA) is a rare and acquired autoimmune subepidermal bullous disease of skin and mucosa. EBA includes various distinct clinical manifestations resembling genetic dystrophic epidermolysis bullosa (DEB), Bullous pemphigus, Brunsting-Perry pemphigoid, or cicatricial pemphigoid. These patients have autoantibodies against type VII collagen (C7), an integral component of anchoring fibrils (AFs), which are responsible for attaching the dermis to the epidermis. Destruction or perturbation of the normal functioning AFs clinically results in skin fragility, blisters, erosions, scars, milia, and nail loss, all features reminiscent of genetic dystrophic epidermolysis bullosa. These anti-C7 antibodies are "pathogenic" because when injected into a mouse, the mouse develops an EBA-like blistering disease. Currently, treatment is often unsatisfactory; however, some success has been achieved with colchicine, dapsone, photopheresis, plasmapheresis, infliximab, rituximab, and IVIG.

Epidermolysis bullosa acquisita

Epidermolysis bullosa acquisita (EBA) is a rare, acquired, chronic subepidermal bullous disease of the skin and mucosa characterized by autoantibodies to type VII collagen (C7) structures, a major component of anchoring fibrils, which attach the epidermis to the dermis. EBA patients have tissue-bound and circulating antitype C7 autoantibodies that attack type C7 and result in a reduction or perturbation of normally functioning anchoring fibrils. Patients with EBA have skin fragility, blisters, erosions, scars, milia, and nail loss, all features reminiscent of genetic dystrophic epidermolysis bullosa. These immunoglobulin G antitype C7 antibodies are pathogenic, because when they are injected into mice, the mice develop an EBA-like blistering disease. In addition to the classical mechanobullous presentation, EBA also has several other distinct clinical syndromes similar to bullous pemphigoid, Brunsting-Perry pemphigoid, or cicatricial pemphigoid. Although treatment for EBA is often unsatisfactory, some therapeutic success has been achieved with colchicine, dapsone, plasmapheresis, photopheresis, infliximab, and intravenous immunoglobulin.

Intravenous immunoglobulin in the treatment of autoimmune bullous dermatoses: an update

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.

Treatment of epidermolysis bullosa acquisita with intravenous immunoglobulin in patients non-responsive to conventional therapy: clinical outcome and post-treatment long-term follow-up

BACKGROUND

Epidermolysis bullosa acquisita (EBA) is a chronic subepidermal blistering disease that is caused by antibodies binding to type VII collagen within anchoring fibrils. It is rare disease with an incidence of 0.25 cases per 1,000,000 population.

OBJECTIVE

The objective of this study is to report the treatment outcomes with intravenous immunoglobulin (IVIg) therapy in 10 patients with severe and widespread EBA non-responsive to conventional therapy.

METHODS

Patients were treated according to a protocol published in a Consensus Statement to treat autoimmune mucocutaneous blistering diseases, including EBA with IVIg. A dose of 2 g/kg/cycle was used.

RESULTS

Ten patients: four males and six females, all were North American Caucasian. The age at onset varied from 37 to 75 years (mean 57.4). A satisfactory clinical response was observed in all 10 patients. The patients received 16-31 cycles (mean 23.1) of IVIg over a period of 30-52 months (mean 38.8). Once IVIg was initiated, earlier drugs (prednisone, dapsone and others) were gradually withdrawn over a 5-9 month period (mean 7.2). Thereafter, IVIg was used as monotherapy. No serious side-effects were observed. The follow-up period since discontinuation of IVIg varied from 29 to 123 months (mean 53.9). During this follow-up period, recurrence of disease was not observed.

CONCLUSION

The data suggest that IVIg can produce a long-term sustained clinical remission in patients with EBA. In the patients, of this study concomitant therapy could be discontinued and IVIg was used as monotherapy.

Imunoglobulina intravenosa para tratamento de epidermólise bolhosa adquirida grave refratária a terapia imunossupressora convencional

A epidermólise bolhosa adquirida é doença bolhosa subepidérmica crônica e rara. Geralmente, inicia-se na fase adulta, sendo a etiologia desconhecida, embora vinculada à presença de anticorpos contra o colágeno tipo VII. Há formação de bolhas, espontaneamente ou após trauma, podendo causar complicações graves. O tratamento é desapontador e difícil. Além da terapia convencional com corticoides sistêmicos, recentemente, novas modalidades terapêuticas promissoras estão sendo utilizadas, dentre elas, a imunoglobulina intravenosa. Destaca-se, neste relato, o difícil manejo clínico desta doença, e a melhora importante com a imunoglobulina intravenosa.

High-dose intravenous immunoglobulin (IVIG) therapy in autoimmune skin blistering diseases

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.

The use of i.v. IG therapy in dermatology

The intravenous administration of exogenous pooled human immunoglobulin (i.v. IG) was originally licensed as antibody replacement therapy in patients with primary immunodeficiencies and there are currently six FDA-approved uses for this agent. Despite a current lack of FDA approval, off-label treatment of a multitude of dermatologic disorders with i.v. IG has shown exciting potential for this unique treatment modality. The diseases successfully treated with i.v. IG include autoimmune bullous diseases, connective tissue diseases, vasculitides, toxic epidermal necrolysis, and infectious disorders (such as streptococcal toxic shock syndrome). Currently the biggest drawback in the consideration of i.v. IG therapy in dermatologic disorders is the lack of randomized controlled trials. Nevertheless, there is a significant body of evidence demonstrating the efficacy of i.v. IG in patients with dermatologic disorders that are resistant to treatment with standard agents. In summary, i.v. IG constitutes a valuable and potentially life-saving agent in managing patients with a variety of dermatologic disorders under the appropriate circumstances.

Epidermolysis bullosa acquisita and neuroendocrine pancreatic cancer – Coincidence or patho-genetic relationship?

The etiology of epidermolysis bullosa acquisita (EBA) is unknown. EBA may be associated with other autoimmune systemic diseases; it also has been described in connection with different malignant tumors, showing complete remission after successful treatment of the tumor. In such cases, EBA may be regarded as a paraneo-plastic dermatosis. We detected a highly differentiated neuroendocrine pancreatic cancer in a 78-year-old woman with EBA. Even thought her tumor was completely removed and the patient has been disease-free for over seven years, a complete regression of her autoimmune bullous dermatosis could not be induced. By using intravenous immunoglobulins in combination with mycophenolate mofetil, further blister formation could be ameliorated.

Canadian consensus statement on the use of intravenous immunoglobulin therapy in dermatology

BACKGROUND

As a safe, well-tolerated, and potentially beneficial therapy, intravenous immunoglobulin (IVIG) has been increasingly used by dermatologists to treat immune-mediated skin disease. However, practical and comprehensive guidelines for the use of IVIG have yet to be established.

OBJECTIVE

To develop the first Canadian consensus statement on the use of IVIG therapy in skin disease.

METHODS

A group of Canadian dermatologists convened to discuss current issues in IVIG therapy. The participants reviewed and evaluated the literature and shared clinical experience. Using a modified Delphi process, a consensus statement was developed.

RESULTS

Herein we provide a brief overview of pemphigus vulgaris, pemphigus foliaceus, bullous pemphigoid, mucous membrane pemphigoid, epidermolysis bullosa acquisita, Stevens-Johnson syndrome, and toxic epidermal necrolysis. Recommendations for the management of these diseases are detailed, and therapeutic algorithms for the treatment of various autoimmune mucocutaneous blistering diseases are presented. The appropriate use of IVIG therapy is placed in context for each disease.

CONCLUSION

Although preliminary data suggest that IVIG is a safe and effective therapy for many skin disorders, uncontrolled clinical trials, case series, and anecdotal case reports dominate the literature. Collaborative randomized controlled trials are required to firmly establish the role of IVIG in dermatology.

High-dose intravenous immunoglobulins for the treatment of autoimmune mucocutaneous blistering diseases: evaluation of its use in 19 cases

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.

Therapy of autoimmune bullous diseases

Autoimmune bullous diseases result from an immune response to molecular components of the desmosome or basement membrane. Bullous diseases are associated with a high degree of morbidity and occasional mortality. Therapy of bullous diseases consists of suppressing the immune system, controlling inflammation and improving healing of erosions. The therapeutic agents used in the treatment of bullous diseases may be associated with high morbidity and occasional mortality. Successful treatment requires understanding of the pathophysiology of the disease process and the pharmacology of the drugs being used.

Off-label uses of biologics in dermatology: Interferon and intravenous immunoglobulin (Part 1 of 2)

The introduction of a number of biologic therapies into the market has revolutionized the practice of dermatology. These therapies include interferons, intravenous immunoglobulin, infliximab, adalimumab, etanercept, efalizumab, alefacept, and rituximab. Most dermatologists are familiar with the Food and Drug Administration-approved indications of these medications. However, numerous off-label uses have evolved. As part 1 of a 2-part series, this article will review the literature regarding the off-label uses of the interferons and intravenous immunoglobulin in dermatology.

Use of intravenous immunoglobulin therapy in autoimmune blistering diseases

Autoimmune mucocutaneous blistering diseases (AMBD) are an interesting group of rare diseases that affect the mucous membranes and the skin and are frequently or potentially fatal. The clinical presentation is significantly variable, as is the course and prognosis. The immunopathology is well characterized and the target antigens to which the autoantibodies are directed have been studied by various investigators. A significant majority of the patients respond to conventional therapy, which consists of high-dose long-term systemic corticosteroids and immunosuppressive agents. This treatment program has significantly improved the prognosis in many patients. In such patients, significant side effects of the drugs may appear and produce a very poor quality of life. In patients with progressive diseases, especially those with mucous membrane pemphigoid, the significant sequela; such as blindness, aphonia, and stenosis of the anal and vaginal canals can occur. In several patients treated with conventional immunosuppressive therapy, death occurs as a consequence of prolonged immune suppression leading to opportunistic infections. In this manuscript, the published data on the use of immunoglobulins intravenous (IGIV) in patients with AMBD is presented. The most important features of IGIV in patients with AMBD are: 1) the ability to clinically control the disease; 2) the ability to induce and maintain a long-term clinical remission; 3) a lower incidence of side effects; and 4) a higher quality of life. The important characteristic of the IGIV therapy in the AMBD is two-fold. First, the therapy, when given according to a published protocol, produces a lasting and long-term clinical remission, rather than a temporary arrest of the disease. Second, the therapy, as described in the protocol, has a very definitive endpoint. Consequently, once the patients are treated and go into long-term remission, the therapy is no longer required. The significant positive results obtained with IGIV are to a large extent also due to the associated aggressive topical therapy that was used and the frequent use of sublesional injections with triamcinolone. The rapid and early detection of cutaneous and mucosal infections and their treatment with systemic antibiotics is also a very important feature of IGIV therapy. When patients are under long-term conventional therapy, the infections are often not detected because they lack the ability to mount signs of inflammation. It is also becoming increasingly clear for patients to have a successful outcome, in treatment with IGIV therapy, it is critical that the physician spends a significant amount of time with each patient, monitor the therapy closely, and be familiar with the overall health of the patient. It is also best if the therapies are instituted by a physician who has significant interest and experience in blistering diseases and IGIV therapy.

Treatment of autoimmune mucocutaneous blistering diseases with intravenous immunoglobulin therapy

Autoimmune mucocutaneous blistering diseases (AMBDs) are a group of rare diseases that affect the skin and mucous membranes and are potentially fatal. They have variable clinical presentation, course and prognosis. Their immunopathology is well-characterised and target antigens have been studied. Many patients respond to conventional therapy, which consists of high-dose long-term systemic corticosteroids with an immunosuppressive agent, but side effects develop that can produce a poor quality of life. Many patients develop significant sequelae, such as blindness, loss of voice, vaginal and anal stenosis. In most patients cause of death is opportunistic infections secondary to immune suppression. To date, intravenous immunoglobulin (IVIg) has been reported to have benefited 156 patients with AMBDs. Its most important features include the ability to reduce or eliminate conventional therapy, the enabling of clinical control, the ability to induce and maintain long-term clinical remission, the capacity for usage based on a defined protocol with a described end point and a resulting increase in quality of life. IVIg produces the best clinical outcome when combined with aggressive topical therapy, sublesional injections of triamcinolone and rapid detection, and early treatment of cutaneous and mucosal infection. Successful therapy requires a physician to spend significant time with each patient. This manuscript provides the opinion of the author on the current use of IVIg to treat AMBDs.

Management of autoimmune bullous diseases: Pharmacology and therapeutics

Bullous diseases are associated with high morbidity and mortality. They result from autoimmune response to one or more components of the basement membrane or desmosomes. Management consists of treating the immunologic basis of the disease, treating the inflammatory process involved in lesion formation, and providing supportive care both locally and systemically. Therapeutic agents are chosen based on their known pharmacologic properties and evidence of effectiveness derived from observations and studies. Learning objectives At the completion of this learning activity, participants should be able to understand the pharmacology of drugs used in the treatment of bullous diseases, the principles of therapy for various such diseases, and a practical approach to the management of these diseases.

[Mucosal epidermolysis bullosa acquisita complicated by laryngeal stenosis]

Epidermolysis bullosa acquisita (EBA) is an acquired chronic autoimmune blistering skin disease that rarely affects mucous membranes. We report a 75-year-old female patient who had EBA restricted to oral, nasal and laryngeal mucous membranes with life-threatening laryngeal stenosis.

Psoriasis: response to high-dose intravenous immunoglobulin in three patients

Treatment of recalcitrant psoriasis and psoriatic arthritis can be challenging, with treatment options limited by drug intolerance or poor efficacy. High-dose intravenous immunoglobulin (hdIVIg) has been used successfully in Kawasaki's disease and idiopathic thrombocytopenic purpura, where it has become the standard treatment. The literature also suggests its positive effect in the treatment of dermatological conditions, such as autoimmune chronic urticaria, atopic dermatitis, scleromyxoedema, dermatomyositis and autoimmune bullous disorders. We report three patients with treatment-resistant psoriasis and psoriatic arthritis who improved with hdIVIg.

Emerging treatment for epidermolysis bullosa acquisita

Epidermolysis bullosa acquisita (EBA) is a rare, chronic, subepidermal, mucocutaneous blistering disease characterized by skin fragility and spontaneous as well as trauma-induced blisters that heal with scar formation and milia. Treatment is often frustrating because conventional therapy with corticosteroids and immunosuppressive agents frequently does not result in significant clinical improvement. We review the conventional treatment of EBA and critically analyze the literature on various adjuvants and therapeutic modalities that have recently been used. These include cyclosporine, colchicine, plasmapheresis, extracorporeal photochemotherapy, and intravenous gammaglobulins. Although the data are preliminary, they suggest that intravenous immunoglobulins may be a promising treatment modality for resistant, nonresponsive, or refractory EBA. The use of intravenous immunoglobulins results in significant improvement of skin and mucosal lesions, and it is quite safe, with minimal side effects.

A review of high-dose intravenous immunoglobulin (hdIVIg) in the treatment of the autoimmune blistering disorders

High-dose intravenous immunoglobulin (hdIVIg) is being used increasingly for dermatological indications. Its mode of action is via a number of proposed mechanisms and it is not associated with the many side-effects of steroids and other immunosuppressive agents. The evidence for using hdIVIg in the treatment of autoimmune bullous disorders is based on uncontrolled trials and case reports. However, there are now 62 reported patients and this review aims to make a critical assessment of the current data. This has been obtained from a Medline search of the English literature from 1966 to 2000 for pemphigus vulgaris, pemphigus foliaceus, bullous pemphigoid, pemphigoid gestationis, cicatricial pemphigoid, epidermolysis bullosa acquisita and linear IgA disease. Taken together hdIVIg was effective in 81% of the patients with blistering disease. Patients appear to be more likely to respond when hdIVIg is used as adjunctive therapy (91% response rate) than as monotherapy (56% response rate). hdIVIg may offer a safe potential therapeutic avenue for resistant cases of the autoimmune bullous disorders but should be further assessed using double-blind placebo-controlled trials.

High-dose intravenous immune globulin for the treatment of autoimmune blistering diseases: an evaluation of its use in 14 cases

High-dose intravenous immune globulin (IVIG) is used to treat a wide variety of autoimmune diseases. We report our experiences of its use in a retrospective study of 14 patients with autoimmune blistering diseases, namely epidermolysis bullosa acquisita (EBA), two; bullous pemphigoid (BP), two; pemphigoid gestationis (PG), one; nodular pemphigoid, two; and pemphigus vulgaris (PV), seven. Two patients with refractory EBA improved following regular courses of IVIG given as monotherapy. IVIG had a steroid-sparing effect in 10 patients with PV, BP and PG. However, the clinical effects were transient and of variable intervals, and repeated courses of IVIG were required. The rapid actions of IVIG were of particular benefit in two patients with extensive, rapidly progressive PV and in one patient with BP in whom swift disease control was required. In such cases, when rapid disease control is paramount, we recommend IVIG used in conjunction with conventional treatments as a safer and less invasive alternative to plasmapheresis. IVIG was ineffective in two patients with nodular pemphigoid. Analysis of indirect immunofluorescence (IIF) titres before and after IVIG showed that a fall in titre occurred after 78% of treatments and was observed in all disease groups. However, like the clinical improvements, the falls in IIF titres were transient and of variable interval, and titres rose back to pretreatment levels in all but one patient. IVIG appears to be beneficial under certain circumstances for the treatment of autoimmune blistering diseases but controlled trials are required to define its therapeutic role further.

Treatment of autoimmune blistering diseases

The treatment of autoimmune blistering diseases remains therapeutically challenging. Significant improvement in the management of autoimmune bullous diseases has occurred as a consequence of improvements in our ability to predict, monitor, and treat the deleterious effects associated with the drugs used to treat these conditions and the introduction of new agents with lower toxicity. Examples include improvements in monitoring and preventing osteoporosis in patients on long-term systemic corticosteroids, the detection of those at risk for azathioprine toxicity bowing to low thiopurine methyltransferase activity, and the addition of agents such as mycophenolate mofetil and IVIG to our therapeutic armamentarium. These advances offer the promise of improved disease control with fewer side-effects and long-term toxicity for our patients.

Esophageal Stricture in a Patient with Epidermolysis Bullosa Acquisita: Endoscopic and Medical Management

Background:

This 40-year-old man with extensive and severe epidermolysis bullosa acquisita (EBA) developed an esophageal stricture that caused dysphagia and limited his nutritional intake.

Objective:

The purpose of the evaluation and management was to relieve the symptomatic obstruction so that he could better swallow food and medications.

Methods:

Endoscopic visualization of the stricture allowed for balloon dilation to be effected. The radial forces applied probably allowed for a less traumatic intervention than the linear shearing forces of bougienage.

Results:

The stricture widened and immediately provided less dysphagia and better tolerance in ingesting food. Medical treatment with sucralfate, known to bind to and protect ulcer bases, also improved his symptoms.

Conclusions:

Esophageal strictures are relatively uncommon in patients with EBA; however, when faced with a stricture in this or other scarring bullous diseases that affect the esophagus, endoscopic balloon dilation combined with postprocedure sucralfate offers improvement with advantages over older methods of intervention.
