Filter by:Bullous pemphigoid (BP) is a chronic autoimmune subepidermal blistering disease primarily affecting the elderly with a significant risk of mortality and morbidity. Various inflammatory cells such as eosinophils, lymphocytes, neutrophils and their granulopoiesis play an important role in the pathogenesis of BP. Infiltration of peripheral blood eosinophils, lymphocytes, and neutrophils into the skin is considered a major feature of BP, making it a heterogeneous disease with different histologic and clinical subtypes. This clinical study was conducted to further investigate the impact of different pathologic phenotypes of BP on the treatment and prognosis of the disease. A retrospective epidemiologic investigative approach was used，and case collection included demographic information, medical history, clinical manifestations, and histopathologic features. Including gender, age, duration of disease, number of days of hospitalization, mucosal involvement, clinical diagnosis before admission, histopathological diagnosis, laboratory tests, concomitant diseases, treatment and its changes in laboratory indexes before and after treatment.
Bullous pemphigoid (BP) is an autoimmune subepidermal blistering disorder most commonly affecting the older population between 60-80 years old. The characteristic feature of BP is itchy patches associated with blisters and erosions. BP significantly affects the patient's quality of life as it causes physical discomfort with itchy patches, blisters, and erosions. Several pieces of evidence from previous studies showed that the production of autoantibodies against the hemidesmosomal anchoring proteins BP180 (Bullous Pemphigoid antigen (BPAG 2)) and BP230 (BPAG 1) is the most common cause for bullous pemphigoid. Therapeutic latency, lack of efficacy in many patients, and adverse drug reactions are the primary concerns in the current bullous pemphigoid treatment paradigm, including high-dose steroid treatment. To overcome these treatment challenges, combination therapy with agents having a steroid-sparing effect like mycophenolate mofetil, cyclophosphamide, azathioprine, and Methotrexate are tested as an add-on to low-dose steroids. 8So other immunosuppressive agents with better safety profiles and more efficacy, like Dapsone and Methotrexate as an add-on to low-dose steroids, can be used. Investigator's literature search found no randomized controlled trial with Dapsone versus Methotrexate as an add-on to first-line steroid has been conducted to compare the efficacy and safety in bullous pemphigoid patients. So, a randomized controlled trial has been planned to evaluate the safety and efficacy of add-on methotrexate versus Dapsone in bullous pemphigoid patients.
ARGX-113-2010 is an open-label extension study with the aim to provide supporting evidence that efgartigimod PH20 SC is a safe and effective long-term treatment for bullous pemphigoid (BP), providing symptom control and eventually remission, while also reducing the cumulative exposure to oral corticosteroids (OCS). All participants who complete the end-of-treatment period (EoTP) visit at week 36 in ARGX-113-2009 will be invited to enroll. In ARGX-113-2009, participants received efgartigimod PH20 SC or placebo with concurrent OCS, or rescue therapy (without efgartigimod PH20 SC or placebo). Depending on their clinical status at the time of rollover into ARGX-113-2010, participants may stop, continue or initiate efgartigimod PH20 SC treatment. In ARGX-113-2010, participants will stop efgartigimod PH20 SC treatment when they achieve complete remission (CR) or partial remission (PR) while being off other concurrent BP therapy for at least 8 weeks. Participants not in CR or PR while off OCS for ≥8 weeks and not on rescue therapy will either start or continue efgartigimod PH20 SC treatment, while maintaining the treatment allocation of ARGX-113-2009 blinded. Participants may also be retreated with efgartigimod PH20 SC after a relapse. In this study, loading doses of 2000 mg (on day 1 and day 8 of a treatment course) and weekly maintenance doses of 1000 mg will be used.
This study assesses the disinfectant and healing promoting effect of ozonated olive oil in treatment of pemphigus vulgaris and bullous pemphigoid in comparison to conventional topical treatment with topical antibiotic.
Pemphigus is a rare autoimmune life-threatening blistering condition affecting skin and mucous membranes. Pemphigus belongs to a family of polygenic disorders. Several different genes encoding molecules regulate pemphigus autoimmunity. Many trials focused on HLA investigation. Increased levels of certain HLA class II alleles frequencies in pemphigus have been reported in various populations. However, they were not investigated in the Russian population. The aim of our study is to investigate HLA class II alleles and haplotypes in Russian patients with pemphigus. Methods Patients and controls We are recruiting 120 patients with pemphigus. The diagnosis was based on clinical and histopathological findings and confirmed by immunofluorescent techniques (direct and indirect immunofluorescent tests). Before sampling, written consent was obtained from each subject. A single blood sample for HLA typing was obtained from all subjects. This study has been approved by the Ethics Committee of Sechenov University, Russia. Phenotypic and allelic frequencies were compared with healthy blood donors (n=100) registered in Sechenov University blood center.
Immune checkpoint inhibitors (monoclonal antibodies targeting cytotoxic T lymphocyte-associated antigen-4 (CTLA-4), programmed cell death protein 1 (PD-1) or programmed death ligand 1 (PD- L1)) have revolutionized the treatment of many cancers. The widespread use of these treatments has triggered a new spectrum of immune related adverse events (irAE). Several cases of bullous pemphigoid (BP) triggered by antiPD-1/PDL-1 therapy have been reported, and their characteristics are currently poorly described in the literature. The investigators sought to collect the French cases of BP triggered by antiPD-1/PDL-1 therapy, and to describe their clinical, biological and histological characteristics. In this national, retrospective, observational study, investigators included patients treated with antiPD-1/PDL-1 therapy, with a diagnosis of bullous pemphigoid occurring during treatment or up to 12 months after its discontinuation. Diagnosis of BP was made by the dermatologist and was based on the following criteria: compatible clinical presentation, compatible histopathology findings, positive direct immunofluorescence (DIF) studies, positive enzyme-linked immunosorbent assay BP180/enzyme-linked immunosorbent assay BP230.
Bullous pemphigoid is the most common type of bullous skin disease and is clinically characterized by clear-tense bullae, which result in post-bullous cutaneous erosions, altering the skin barrier. The treatment of this pathology consists of the application of high doses of topical corticosteroids (clobetasol propionate) for a prolonged period of at least 6 months. The main objective of this study is to demonstrate a change in bone mineral density at 6 months after initiation of treatment, in subjects with bullous pemphigoid and treated with topical corticosteroid.
Bullous pemphigoid (BP) is the most common autoimmune bullous dermatosis. It mainly affects the elderly, and its cutaneous manifestations are extremely varied. Since the publication of the first case of PB associated with sulfasalazine in 1970, several drugs have been reported for their potential link with the development of PB. Recently, cases of PB associated with dipeptidyl peptidase-IV (DPP4) inhibitors, also known as gliptins, have been reported. DPP4 inhibitors are oral antidiabetic agents prescribed to patients with type 2 diabetes, as monotherapy, in combination with other oral antidiabetic agents or with insulin. In recent years, an increasing number of cases have been published, describing the potential role of gliptins in PB induction. All these clinical cases and pharmacovigilance analyzes tend to show an increased risk of developing BP in case of gliptin exposure. The main objective is to evaluate the risk of developing a PB under DPP4 inhibitor treatment, comparing cases of diabetic patients with BP, to matched diabetic controls for sex and age, from French departments. Endocrinology in a retrospective study from 1 January 2014 to 31 July 2016. The study will be conducted using databases of clinical and histological records. The investigators will perform a retrospective 1: 2 case-control study comparing cases with type 2 diabetes and BP to matched diabetic controls for sex and age, randomly drawn from French endocrinology departments (Marseille La Conception ) and Switzerland (Bern), between January 1, 2014 and July 31, 2016. the investigators will compare gliptin exposure in the case-control group versus the control group, adjusting for potential confounding bias using models. logistic regression.
Autoimmune bullous dermatoses include pemphigus, bullous pemphigoid, pemphigoid gestationis, linear IgA dermatosis, mucous membrane pemphigoid, lichen planus pemphigoid, anti-p200 pemphigoid, epidermolysis bullosa acquisita and dermatitis herpetiformis. Autoimmune bullous dermatoses are rare and have an incidence of 20-60 new cases per 1 million person- year in Europe. The incidence of the individual entities is slight significantly different within Europe, but strongly also in comparison to other countries such as Kuwait, Singapore, USA and South America. The most common of these disorders is the bullous pemphigoid. A considerable progress has been made in the last years to elucidate the pathogenic role of autoantibodies in these diseases. To this end, various in vitro and animal experiments have been used to understand some basic pathophysiological mechanisms in these diseases. Further studies are currently being carried out to explain a precise elucidation of the disease process and to be able to treat the patients targeted later. At present, however, no data are available to explain why certain individuals develop the autoimmune disease and others do not. Epidemiological studies showed some triggers to the development of autoimmune dysregulation, e.g. drugs. Furthermore, it has been shown that genetic factors play a role in the pathogenesis of the disease. A clear association with certain HLA regions have been shown in patients with pemphigus, e.g. about 95% of pemphigus patients from the group of Ashkenazi Jews have the HLA-DRB1*0402 haplotype. Recently, the first non-HLA gene associated with pemphigus was described. For other conditions such as bullous pemphigoid, pemphigoid gestationis or linear IgA dermatosis the association with HLA antigens is less pronounced. Another indication of the importance of the genetic background in these diseases can be elucidated from the observation of autoantibodies at a low concentration in healthy relatives of pemphigus patients.
Pemphigus and bullous pemphigoid (BP) are severe autoimmune blistering diseases (AIBD) that pose a critical need for new therapeutic approaches. Clinical trials in pemphigus and BP will require the availability of validated disease severity measures that can be used to define primary outcomes.
