Filter by:Bullous pemphigoid (BP) is an autoimmune subepidermal blistering disease and typically affects the elderly. Clinically, BP is an intensely pruritic erythematous eruption with widespread blister formation. BP is usually a chronic disease, with spontaneous exacerbations and remissions, which may be accompanied by significant morbidity. BP usually requires on average a 1-year duration of treatment. Superpotent topical corticosteroids have been demonstrated to be effective. Despite their high efficacy, topical corticosteroids are often considered as poorly convenient, requiring the assistance of patients' relatives or a nurse to apply the topical treatment on a long period of time. Overall, whereas BP lesions can be adequately and rapidly controlled with either topical corticosteroids, there is a high need for a safe maintenance therapy to avoid treatment side effects due to cumulative doses of corticosteroids over months. Newer therapeutic agents such as ustekinumab targeting molecules involved in the inflammatory cascade associated with BP represent future alternatives to classical immunosuppressant drugs for maintenance therapy.
Bullous pemphigoid (BP) is the most common of the autoimmune blistering skin diseases in Western Europe. [Joly 2012]The study will recruit the new onset or relapsing mild to moderate BP patients. The study population will consist of patients above the age of 18 years with an active episode of BP, confirmed by inclusion and exclusion criteria and who, in the opinion of the Investigator, would benefit from treatment with rVA576. Recombinant rVA576 is a small protein complement C5 and LTB4 inhibitor, which prevents the cleavage of C5 by C5 convertase and thereby inhibits generation of C5b-9 the membrane attack complex (MAC), as well as preventing the release of the anaphylatoxin C5a. rVA576 is effective in inhibiting terminal complement activity irrespective of the activating pathway (classical, lectin or alternative). This Phase IIa open-label single-arm study will evaluate the safety and efficacy of rVA576 in adult mild to moderate Bullous Pemphigoid patients
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.
This study investigates the differences of Eosinophil Cationic Protein, Tumor Necrosis Factor-alpha and Anti-BP180-NC16A IgG levels of blister fluids in Bullous Pemphigoid patients which appeared before and under treatment subsequently. These molecules will also be measured in blood serum before and under treatment. Changes of titers in serum and differences between blister fluids will be compared to observe whether correlation exists between them. These measures will also be compared between groups of responders and non-responders to the first-line treatment options to analyze correlation with treatment success.
This is a prospective study that aimed to observe the therapeutic effects of minor salivary gland transplantation for cicatrizing conjunctivitis patients.
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.
The purpose of this study is to evaluate the safety and performance of the EYEMATE system in patients undergoing concomitant implantation of a BKPro type 1 and an EYEMATE sensor over the 24 months period beginning at implantation.
Bullous pemphigoid affects mainly elderly patients. It is often associated with neurologic disorders, which represent a major risk factor of the disease
Mucous membrane pemphigoid (MMP) describes a group of chronic auto-immune bullous diseases (AIBD) of the basement membrane zone (BMZ), characterized by predominant or exclusive mucosal involvement, including oral, naso-pharyngeal, laryngo-tracheal, genital, oesophageal, anal and ocular mucous membranes. Circulating autoantibodies are directed against various antigens of the BMZ: BP180, laminin 332 and type 7 collagen. MMP is a rare disease with an incidence of 1.8 new cases/million inhabitants/year in France. Scar formation which is secondary to initial inflammation, is a characteristic feature of MMP, leading to major disability (e.g blindness and oesophageal, anal, vaginal stenosis) and life-threatening situations (e.g. laryngeal stenosis leading to respiratory failure). Dapsone is the first line treatment of mild/moderate forms of MMP. Dapsone is used both as initial treatment, and as maintenance therapy. However, severe forms of MMP can rapidly worsen leading to blindness, aphagia due to esophageal stenosis, respiratory failure due to tracheal or laryngeal stenosis, and urinary and sexual dysfunctions due to genital involvement. These patients are usually treated using immunosuppressive drugs. Indeed, corticosteroids (CS) are not recommended in MMP. Cyclophosphamide was considered as the most effective immunosuppressant in severe forms of MMP, before the use of rituximab, an anti-CD20 monoclonal antibody (MAb). Two series from our group have assessed the advantages and disadvantages of IV pulse and oral administration of cyclophosphamide in MMP. Oral administration seems more rapidly effective with 54% of complete remission (CR) after a median time of 24 weeks (16-52 weeks). The results of 41 patients with severe types of MMP (including a French series of 20 patients) treated with rituximab have been published. Rate of CR after one and two cycles were 66% and 90%, respectively. Clinical improvement was rapid, since a decrease in disease activity was observed after 4 weeks of treatment in 64% of patients. Our results and those of the literature suggest that rituximab might be more effective than cyclophosphamide, which has been considered as the gold standard of treatment in severe forms of disease, up to now.
Bullous pemphigoid (BP) is a chronic, inflammatory, subepidermal, autoimmune blistering disease which mainly develops in the elderly, with onset usually in the late 70s and a substantial increase in incidence in people older than 80 years. If untreated, it can persist for months or years, with periods of spontaneous remissions and exacerbations. It has been found that blisters and sera of BP patients contain abnormally high levels of pro-inflammatory cytokines such as interleukin-6 (IL-6) and IL-8. Recently, it also has been demonstrated that NLRP3 (NACHT, LRR and PYD domains-containing protein 3) inflammasome components (the NLRP3-caspase-1-IL-18 axis) were significantly up-regulated in peripheral blood mononuclear cells from BP patients and positively correlated with disease activity. AC-203 is a topical formulation of an oral modulator of inflammasome and IL-1beta pathways. In vitro studies have demonstrated that AC-203 significantly reduced secretion of IL-6 and moderately reduced IL-8 secretion in HaCaT cells treated with specific anti-BP180 IgG. This study is designed to test the safety, tolerability, efficacy, and pharmacokinetics of AC-203 ointment (vs. a topical steroid comparator representing standard of care) ointment in subjects with BP.
