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. Read More

Introduction: Epidermolysis bullosa (EB) is a relatively infrequent genodermatosis for which there is still no cure, and which impacts the quality of life of those that are affected by it. The Quality of Life evaluation in Epidermolysis Bullosa (QoLEB) questionnaire was specifically developed for English-speaking persons with EB.

Epidermolysis bullosa is a heterogeneous group of rare genetic disorders characterized by mucocutaneous fragility and blister formation after minor friction or trauma. There are four major epidermolysis bullosa types based on the ultrastructural level of tissue cleavage: simplex, junctional, dystrophic, and Kindler epidermolysis bullosa. They are caused by mutations in genes that encode the proteins that are part of the hemidesmosomes and focal adhesion complex. Read More

Janus kinases (JAKs) are a group of intracytoplasmic tyrosine kinase proteins that bind to the cytoplasmic part of the transmembrane cytokine receptors and regulate signaling. The pathophysiology of various autoimmune and autoinflammatory conditions relies on JAK/STAT signaling and therefore, the inhibition of JAK/STAT pathways can be a promising treatment for such diseases, especially inflammatory skin conditions. The current study aimed to evaluate the efficacy of JAK inhibitors in the treatment of immunobullous diseases, including pemphigus, pemphigoid, dermatitis herpetiformis, and epidermolysis bullosa.

Background: Uniparental disomy (UPD) is a condition in which both chromosomes are inherited from the same parent, except for imprinting disorders. Uniparental isodisomy (UPiD) may result in a homozygous variant contributing to an autosomal recessive disorder in the offspring of a heterozygous carrier. Junctional epidermolysis bullosa intermediate (JEB intermediate) is an autosomal recessive inherited disease that is associated with a series of gene variants, including those of COL17A1. Read More

Epidermolysis bullosa acquisita is a rare autoimmune disease, characterized by the synthesis of anti-collagen VII autoantibodies, the main component of hemidesmosome anchoring fibrils. The antigen-antibody binding elicits a complex inflammatory response, which culminates in the loss of dermo-epidermal adhesion of the skin and/or mucous membranes. Skin fragility with bullae, erosions, and milia in areas of trauma characterizes the mechanobullous form of the disease. Read More

Epidermolysis bullosa simplex (EBS) is a severe and potentially life-threatening disorder for which no adequate therapy exists. Most cases are caused by dominant mutations in keratins KRT5 or KRT14, leading to the formation of cytoplasmic keratin aggregates, profound keratinocyte fragility and cytolysis. We hypothesized that pharmacological reduction of keratin aggregates, which compromise keratinocyte integrity, represents a viable strategy for the treatment of EBS. Read More

Epidermolysis bullosa (EB) is a group of skin disorders with skin fragility characterized by blistering from minimal mechanical trauma with rupture at the dermoepidermal junction. There are four major classical heritable EB types, due to mutations in as many as 20 distinct genes: EB simplex (EBS), junctional EB (JEB), dystrophic EB (DEB), and Kindler EB (KEB). This study is aimed at reporting case series on patients ( = 8; males, = 5 and females, = 3, age range 12-68 years) affected by EB and performs a review of the literature on this topic. Read More

Autoimmune bullous diseases (AIBDs) are a group of skin-related disorders that involve damage to structures maintaining cell-cell adhesion, such as desmosomes and hemidesmosomes. Key AIBDs include pemphigus related diseases, pemphigoid related conditions, acquired epidermolysis bullosa (EBA), and dermatitis herpetiformis (DH). Each group of conditions exhibits characteristic clinical lesion patterns and is associated with specific autoantibodies targeting epidermal and dermal structures involved in cell-cell adhesion and skin integrity.

Epidermolysis bullosa (EB) is a group of rare genodermatoses that is characterized by skin fragility resulting from minor trauma. There are four major subtypes, namely, EB simplex, junctional EB, dystrophic EB and Kindler EB, depending upon the localization of defective protein and resulting plane of blister formation. The phenotype is heterogeneous in terms of severity and majority of them present at birth or neonatal period. Read More

Recessive dystrophic epidermolysis bullosa (RDEB) patients develop poorly healing skin wounds that are frequently colonized with microbiota. Because T cells play an important role in clearing such pathogens, we aimed to define the status of adaptive T cell-mediated immunity in RDEB wounds. Using a non-invasive approach for sampling of wound-associated constituents, we evaluated microbial contaminants in cellular fraction and exudates obtained from RDED wounds. Read More

In autoimmune bullous diseases (AIBDs), autoantibodies loosen molecular adhesions in the skin and/or mucosa and lead to blisters and erosions. Immunosuppressive drugs reduce mortality of the AIBD; therefore, patients will have to live longer with comorbidities.

Objective: This study aims to determine the quality of life of AIBD patients undergoing systemic treatment while investigating the survey's relationship with various factors. Read More

Human induced pluripotent stem cell (hiPSC)-derived hair-bearing skin organoids offer exciting new possibilities for modeling diseases like epidermolysis bullosa (EB). These inherited diseases affect 1 in 30,000 people worldwide and result from perturbed expression and/or structure of components of the epidermal-dermal junction (EDJ). To establish whether hiPSC-derived skin organoids might be able to capture salient features of EB, it is thus important to characterize their EDJ. Read More
