Epstein-Barr virus (EBV)-associated T- or natural killer (NK)-cell lymphoproliferative disease (LPD) is a heterogeneous group of disorders characterized by chronic proliferation of EBV-infected lymphocytes. Patients may present with severe skin manifestations, including hypersensitivity to mosquito bites (HMB) and hydroa vacciniforme (HV)-like eruption, which are characterized by blister formation and necrotic ulceration. Skin biopsy specimens show inflammatory reactions comprising EBV-infected lymphocytes...

Bullous pemphigoid (BP) is an autoimmune blistering skin disease characterized by the production of autoantibodies against the hemidesmosomal protein BP180. B regulatory cells (Bregs) are crucial in maintaining self-tolerance and suppressing autoantibody production. However, it is still unclear whether the dysfunctions of Bregs contributes to the autoantibody production in BP patients. In this study, we found that CD19+CD24hiCD27+ Bregs and IL-10+CD19+ Bregs were significantly increased in the peripheral blood samples of BP patients compared with that in healthy controls...

Objective: As a rare autoimmune disease, pemphigus vulgaris has a poor prognosis especially in lack of proper medical support. This blistering disease involves both the skin and mucus membranes. The challenge is improving the healing process of skin lesions of which, superimposed infections are among the main causes of the disease mortality. Accordingly, we aimed to assess the treatment options suggested by traditional Persian medicine (TPM) and compare them with current findings. Materials and Methods: We studied the main clinical and pharmaceutical textbooks of TPM (Kitāb al-hāwīfī al-tibb, the Canon of Medicine, Eksir-e-Aazam, Tuhfat al-mu'minīn, Makhzan al-adviyah (focusing on the skin chapter and respective herbal remedies for the inflamed skin and ulcers...

Pemphigus vulgaris (PV) is a severe autoimmune blistering disease of the skin and mucous membranes. As autoantibodies play an essential role in the disease pathogenesis, the serological detection of anti-desmoglein 3 IgG represents a central tool in the diagnosis of the disease. In this study, we show the validation of a novel lateral flow immunoassay (LFIA) which rapidly detects anti-desmoglein 3 (Dsg3) IgG in human serum. In contrast to other diagnostic procedures, the assay is compact and simple to perform and delivers a fast "yes" or "no" answer within 10 min without additional hardware requirements for test evaluation...

Azathioprine (AZP) is used as a corticosteroid (CS)-sparing medication to treat autoimmune blistering diseases. In this study, we examined the efficacy of AZP and the feasibility of using AZP monotherapy (without CS) to treat pemphigus and pemphigoid. We performed a retrospective study of 10 Japanese patients (seven with pemphigus and three with pemphigoid) with mild to moderate disease activity who had been treated using AZP. The treatment efficacy was evaluated based on decreases in the disease activity scores and autoantibody titers...

Chronic wounding as a result of recurrent skin blistering in the painful genetic skin disease epidermolysis bullosa, may lead to life-threatening infections, increased risk of tumor formation, and other serious medical complications. Therefore, epidermolysis bullosa patients have an urgent need for optimal wound care and tissue regeneration. Therapeutic strategies using gene-, protein-, and cell-therapies are being developed to improve clinical symptoms, and some of them have already been investigated in early clinical trials...

Eosinophils are typically associated with unique inflammatory settings, including allergic inflammation and helminth infections. However, new information suggests that eosinophils contribute more broadly to inflammatory responses and participate in local immune regulation and the tissue remodeling/repair events linked with a variety of diseases. Eosinophilic infiltration has long been a histologic hallmark of bullous pemphigoid (BP), a subepidermal autoimmune blistering disease characterized by autoantibodies directed against basement membrane protein BP180...

Lichen planus pemphigoides (LPP) is a rare blistering disease with features of both lichen planus and bullous pemphigoid. LPP typically appears on the extremities and occasionally involves the oral mucosa. Herein, we describe a case of LPP of the vulva of an 80-year-old woman, an uncommon location for this disease process. This clinical scenario can be confused with a number of similarly appearing entities such as erosive vulvar lichen planus, mucous membrane pemphigoid, and erosive lichen sclerosus et atrophicus...

Wound-colonizing microorganisms can form complex and dynamic polymicrobial communities where pathogens and commensals may co-exist, cooperate or compete with each other. The present study was aimed at identifying possible interactions between different bacteria isolated from the same chronic wound of a patient with the genetic blistering disease epidermolysis bullosa (EB). Specifically, this involved two different isolates of the human pathogen Staphylococcus aureus, and isolates of Bacillus thuringiensis and Klebsiella oxytoca...

The occurrence of the autoimmune blistering disease, bullous pemphigoid (BP), in patients with failed renal allograft is rare and the few reported cases suggest various provocative factors without reaching a consensus. Here we report the case of a patient presenting with bullous lesions soon after the complete discontinuation of immunosuppressant therapy following renal allograft failure. Skin biopsy confirmed the diagnosis of BP. Administration of systemic corticosteroid controlled the occurrence of BP lesions in our patient...

Regulatory T cells (Tregs) are well known for their modulatory functions in adaptive immunity. Through regulation of T cell functions, Tregs have also been demonstrated to indirectly curb myeloid cell-driven inflammation. However, direct effects of Tregs on myeloid cell functions are insufficiently characterized, especially in the context of myeloid cell-mediated diseases, such as pemphigoid diseases (PDs). PDs are caused by autoantibodies targeting structural proteins of the skin. Autoantibody binding triggers myeloid cell activation through specific activation of Fc gamma receptors, leading to skin inflammation and subepidermal blistering...

BACKGROUND: Lesions of bullous pemphigoid (BP), an autoimmune subepidermal blistering disease characterized by the presence of tissue-bound and circulating autoantibodies to hemidesmosomal antigens, harbour a mixed inflammatory cellular infiltrate. In various models, neutrophils, eosinophils, mast cells, monocytes as well as B and T cells have been shown to be involved in the pathogenesis of BP. However, their interactions with and effective role in blister formation remains uncertain...

Imatinib mesylate (Glivec; Novartis AG, Basel, Switzerland) is a tyrosine kinase inhibitor which is used in the treatment of oncologic diseases like chronic myeloid leukemia and gastrointestinal stroma tumor (GIST). Among cutaneous side effects, bullous reactions are rare. The authors describe the case of a 66-year-old woman developing blistering and skin fragility on her hands, foot, lower legs, and back after intake of imatinib for treatment of GIST. Biopsy showed vacuolar alteration at the dermoepidermal junction (DEJ) associated with a few lymphocytes and a subepidermal blister...
