pemphigus vulgaris

Marta Sar-Pomian, Lidia Rudnicka, Malgorzata Olszewska
Scalp is a unique location for pemphigus because of the abundance of desmogleins localized in hair follicles. Scalp involvement is observed in up to 60% of patients in the course of pemphigus. The lesions may occasionally lead to alopecia. Unforced removal of anagen hairs in a pull test is a sign of high disease activity. Direct immunofluorescence of plucked hair bulbs is considered a reliable diagnostic method in patients with pemphigus. Follicular acantholysis is a characteristic histopathological feature of pemphigus lesions localized on the scalp...

Pemphigus vulgaris (PV) is an autoimmune skin blistering disease effecting both cutaneous and mucosal epithelia. Blister formation in PV is known to result from the binding of autoantibodies (autoAbs) to keratinocyte antigens. The primary antigenic targets of pathogenic autoAbs are known to be desmoglein 3, and to a lesser extent, desmoglein 1, cadherin family proteins that partially comprise the desmosome, a protein structure responsible for maintaining cell adhesion, although additional autoAbs, whose role in blister formation is still unclear, are also known to be present in PV patients...

It has been more than 40 years since the dual descriptions of canine pemphigus vulgaris. Over the ensuing four decades, the reports of-mostly canine-novel autoimmune skin diseases (AISDs) have progressed in successive waves separated by long periods of quiescence. This Editorial introduces a series of comprehensive review papers on the various canine and feline AISDs. This collection of articles aims at remediating the current veterinary literature deficiency on this topic by summarizing the key historical, clinical, histological, immunological and treatment characteristics of animal AISDs...

Expression of microRNA-338-3p (miR-338-3p) was aberrantly elevated in pemphigus vulgaris (PV), although its role in PV is still unknown. The present study investigated the functional role and possible molecular mechanisms of miR-338-3p in PV. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was performed to detect miR-338-3p expression in peripheral blood mononuclear cells (PBMCs) from patients with PV. Correlation with disease severity and anti-desmoglein 3 antibody (anti-Dsg3) titers were analyzed in patients with PV...

Pemphigus vulgaris (PV) is a life-threatening disease belonging to the pemphigus group of autoimmune intra-epidermal bullous diseases of the skin and mucosae. The therapeutic management of PV remains challenging and, in some cases, conventional therapy is not adequate to induce clinical remission. The cornerstone of PV treatment remains systemic corticosteroids. Although very effective, long-term corticosteroid administration is characterized by substantial adverse effects. Corticosteroid-sparing adjuvant therapies have been employed in the treatment of PV, aiming to reduce the necessary cumulative dose of corticosteroids...

We read with interest a study by Miyamoto et al. published in the Journal of European Academy of Dermatology and Venereology. In their study, Miyamoto et al. found higher expression of vascular endothelial growth factor (VEGF) and endoglin in the tissue of erythrodermic pemphigus foliaceous (PF) compared to non-erythrodermic PF. According to the authors, both VEGF and endoglin may pose a prognostic predicting factors for adequate tissue repair in pemphigus patients; PF& pemphigus vulgaris (PV). The authors stated "therapy such as topical propranolol may enable adequate healing and disease remission"...

We appreciate the valuable comments from Drs. Abdelmaksoud and Vestita regarding our study about the in situ expression of vascular endothelial growth factor (VEGF) and endoglin in patients with pemphigus foliaceus (PF) and pemphigus vulgaris [1]. We proposed that the severity of PF is related not only to the level of circulating autoantibodies but also to the ability to restore tissue integrity following intraepidermal detachment. We have demonstrated that overexpression of VEGF is observed both in serum samples[2] and skin fragments obtained from patients with severe PF[3], and suggested the use of β-blockers to regulate it...

BACKGROUND: Kaposi's sarcoma (KS) is a rare endothelial neoplasm caused by the human herpes virus 8 (HHV-8). Its risk is increased in immunocompromised patients, including those undergoing immunosuppressive therapy for autoimmune bullous diseases. Conversely, HHV-8 infection has been hypothesized to be a triggering factor of bullous diseases, especially pemphigus. Given the fact that both KS and autoimmune bullous diseases have a low incidence in the general population, it could be expected that the association between these disorders would be exceptional...

Autoimmune blistering diseases are characterized by autoantibodies against structural adhesion proteins of the skin and mucous membranes. Extensive characterization of their autoantibody targets has improved understanding of pathogenesis and laid the basis for the study of antigens/epitopes diversification, a process termed epitope spreading (ES). In this review, we have reported and discussed ES phenomena in autoimmune bullous diseases and underlined their functional role in disease pathogenesis. A functional ES has been proposed: (1) in bullous pemphigoid patients and correlates with the initial phase of the disease, (2) in pemphigus vulgaris patients with mucosal involvement during the clinical transition to a mucocutaneous form, (3) in endemic pemphigus foliaceus, underlining its role in disease pathogenesis, and (4) in numerous cases of disease transition associated with an intermolecular diversification of immune response...

Desquamative gingivitis is a clinical finding with several potential etiologies. Among the most common are oral lichen planus, cicatricial pemphigoid, and pemphigus vulgaris, though various other differential diagnoses exist. The presence of desquamative gingivitis often results in poor oral hygiene, which can have downstream consequences, including periodontitis and tooth loss. Though certain mucosal findings may be suggestive of a particular diagnosis, a thorough history, physical examination, and appropriate dermato- and immunopathologic assessment is necessary for narrowing this broad differential diagnosis...

Pemphigus vulgaris (PV) belongs to an autoimmune disease cluster that includes autoimmune thyroid disease (AITD), suggesting common mechanisms driving autoimmune susceptibility. Our group has shown that PV patients exhibit significant reactivity to AITD-related anti-thyroid peroxidase (anti-TPO), and anti-TPO antibodies affect signaling pathways in keratinocytes similar to anti-desmoglein (Dsg) 3 antibodies. To further assess the relevance of anti-TPO reactivity in PV, we analyzed anti-TPO levels in 280 PV and 167 healthy control serum samples across a comprehensive set of variable and static parameters of disease activity and etiopathogenesis...

Paraneoplastic pemphigus is a severe autoimmune blistering disease presenting in the setting of underlying malignancy. Paraneoplastic pemphigus is associated with diffuse painful stomatitis throughout the oral cavity with extension to the lips. The cutaneous findings are varied and have been described as lichenoid, pemphigoid, and targetoid lesions. Herein, we report a patient with paraneoplastic pemphigus whose routine testing led to a diagnosis of pemphigus vulgaris. However, further testing was pursued revealing an antibody profile consistent with paraneoplastic pemphigus...

Keratins are crucial for the anchorage of desmosomes. Severe alterations of keratin organization and detachment of filaments from the desmosomal plaque occur in the autoimmune dermatoses pemphigus vulgaris and pemphigus foliaceus (PF), which are mainly caused by autoantibodies against desmoglein (Dsg) 1 and 3. Keratin alterations are a structural hallmark in pemphigus pathogenesis and correlate with loss of intercellular adhesion. However, the significance for autoantibody-induced loss of intercellular adhesion is largely unknown...
