Project description:ImportanceDupilumab is a theoretically novel therapy for bullous pemphigoid (BP). However, its effectiveness and safety have yet to be confirmed in a large-scale study.ObjectiveTo assess the efficacy and safety of dupilumab in patients with BP and evaluate factors that potentially affect short-term and long-term outcomes.Design, setting, and participantsA retrospective cohort study was conducted from January 1, 2021, to July 31, 2022. The median (IQR) follow-up period was 24.6 (11.5-38.4) weeks. This multicenter study was performed in 6 dermatology departments of the National Autoimmune Bullous Diseases Cooperative Group of China. Adult patients with BP that received 300 mg of dupilumab every 2 weeks following an initial dose of 600 mg were included. Patients were eligible if they had a clinical presentation of BP combined with immunological or pathological evidence. Patients with drug-induced BP, with less than 4 weeks of follow-up, and who received dupilumab or any other biologics within 6 months were excluded.Main outcomes and measuresThe primary outcome was the proportion of patients who achieved disease control within 4 weeks. Disease control was defined as the absence of new lesions and pruritus, combined with the healing of existing lesions. Complete remission rates, relapse rates, changes in Bullous Pemphigoid Disease Area Index (BPDAI) scores, itching numerical rating scale (NRS) scores, laboratory results within 64 weeks, and adverse events (AEs) were also assessed.ResultsAmong 146 patients (median [IQR] age, 73 [64-85] years; 86 [58.9%] male patients) included in the study, 127 (87.0%) patients achieved disease control within 4 weeks, with a median (IQR) time of 14 (7-14) days. A total of 52 (35.6%) patients achieved complete remission, and 13 (8.9%) patients relapsed during the observation period. The complete remission rate and cumulative relapse rate at week 64 were 62.5% (5 of 8) and 30.9%, respectively. There was rapid and sustained improvement in clinical indicators and laboratory examination results after dupilumab treatment, including BPDAI scores, itching NRS scores, serum anti-BP180 and anti-BP230 antibodies, total IgE levels, and eosinophil count. Of these 146 patients, 107 (73.3%) did not report any AEs. The most common AEs were infections and eosinophilia. Serum anti-BP180 antibody levels of greater than 50 relative units (RU)/mL (OR, 3.63; 95% CI, 0.97-12.61; P = .045) were associated with 4-week disease control, and male patients were more likely to relapse (HR, 10.97; 95% CI, 1.42-84.92; P = .02).Conclusions and relevanceIn this retrospective cohort study, dupilumab treatment was associated with improved clinical symptoms in patients with BP. The safety profile was favorable, although concurrent infection and eosinophilia might pose potential concerns. This study suggests that patients with anti-BP180 antibody levels of at least 50 RU/mL and female sex may respond better.

Project description:BackgroundBullous pemphigoid (BP) is an autoimmune blistering disorder that predominantly affects the elderly. As the main treatment for BP, systemic corticosteroids are often limited by their side effects. Safer treatment modalities are therefore needed. Dupilumab is a biologic agent used to treat BP in recent years.MethodsMedical records of patients with moderate-to-severe BP were retrospectively reviewed. Twenty-four patients were included (follow-up period: 32 weeks), eight of whom received dupilumab in combination with methylprednisolone and azathioprine (dupilumab group) while the other 16 patients received methylprednisolone and azathioprine (conventional group). Response to dupilumab was evaluated by comparison of several parameters (time to stop new blister formation, time to reduce the systemic glucocorticoids to minimal dose, and total amount of methylprednisolone).ResultsThe median age of patients in the dupilumab and conventional groups were 64.50 years (range: 22-90 years) and 64.50 years (range: 17-86 years), respectively. The median duration of disease before admission in the dupilumab group was 2 months (range: 1-240 months) and 2.5 months (range: 1-60 months) in the conventional group. The median time to stop new blister formation was 8 days (range: 1-13 days) and 12 days (range: 5-21 days) in patients of the dupilumab and conventional groups, respectively (p = 0.028 by Kaplan-Meier analysis). In addition, the median time to reduce the systemic glucocorticoids to minimal dose (methylprednisolone 0.08 mg/kg/day) was 121.5 and 148.5 days for the dupilumab and conventional therapy groups, respectively (p = 0.0053 by Kaplan-Meier analysis). The median total amount of methylprednisolone (at the time of reaching the minimal dose) used in the dupilumab group was 1,898 mg (range: 1,624-2,932 mg) while the cumulative dose of conventional group was 2,344 mg (range: 1,708-4,744 mg) (p = 0.036 by Mann-Whitney U test). The median total amount of azathioprine (at the time of reaching the minimal dose) used in dupilumab group was 8,300 mg (range: 7,100-10,400 mg) while the total dose of conventional group was 10,300 mg (range: 8,900-14,400 mg) (p = 0.0048 by Mann-Whitney U test). No adverse event related to dupilumab was recorded.ConclusionsDupilumab in addition to methylprednisolone and azathioprine seems superior to methylprednisolone/azathioprine alone in controlling disease progression and accelerating the tapering of glucocorticoids.

Project description:Bullous pemphigoid (BP) is the most common autoimmune subepidermal blistering disorder in the elderly. Systemic and topical use of glucocorticoids and immunosuppressants has been shown to be effective in most patients. However, refractory BP patients are challenged to clinicians with severe clinical symptoms, resistance to treatment, and high relapse rate. How to predict and assess the refractory and severity of bullous pemphigoid is the key issue in clinical practice, and the urgent need for precision medicine in refractory patients is driving the search for biomarkers and biologics. Recently, some biomarkers, such as the level of specific autoantibodies and released cytokines, have been proposed as the potential parameters to reflect the disease severity and predict the treatment response and relapse of refractory BP. Moreover, new biologics targeting pathogenic antibodies, complement, Th2 axis, eosinophils, and Th17 axis have shown potent efficacy on refractory BP. Here, we review the literature and give an overview of emerging biomarkers and therapeutic strategies for refractory bullous pemphigoid to improve the prognosis of the patient.

Project description:BackgroundBullous pemphigoid (BP) is an autoimmune skin-blistering disease. Systemic corticosteroids remain the first line treatment for moderate-to-severe BP with the potential for severe adverse events. Dupilumab has emerged as an alternative option for BP patients.ObjectiveWe evaluated the efficiency and safety of dupilumab on BP treatment and explored a mode of drug action in depth.Methods and resultsA multicenter retrospective cohort included 20 BP patients who received dupilumab with or without systemic corticosteroid in dupilumab group, and 20 matched BP patients who received corticosteroid alone in conventional group. Serum samples were collected from 20 patients (10 from dupilumab group and 10 from conventional group) at baseline and week 4. Compared to systemic corticosteroid alone, dupilumab with or without systemic corticosteroid was similarly efficacious in clinical remission at week4 (complete remission plus partial remission: 100%) and week24 (complete remission plus partial remission:100%), but allowing significant decreases in the cumulative doses of corticosteroids with reducing the incidence of adverse events. However, dupilumab did not decrease BP180 antibody despite an obvious clinical improvement. Comparative plasma proteomic analysis performed before and after treatment in 3 BP patients from dupilumab group revealed that drug use was associated with 30 differentially expressed proteins, including 26 down-regulated and 4 up-regulated proteins. The former consisted of immune related proteins involved in T/B cell interactions (inducible T-cell co-stimulator ligand, ICOSL) and in the activation of eosinophils (PRG2), mast cells (S100A12), and complement (CR2). TARC and ICOSL levels correlated with BP severity in patients who received either dupilumab or conventional treatment.ConclusionDupilumab has similar efficacy in treating BP as conventional drugs, by inhibiting the activities of many types of immune cells and complement, and regulating the interactions between T and B cells.

Project description:IntroductionDupilumab has emerged as a promising treatment option for bullous pemphigoid (BP). Rapid identification of responders could avoid the need for additional immunosuppressive treatments that are associated with increased morbidity and mortality.MethodsTo investigate the course of itch as an early indicator of treatment response, data of 12 BP patients treated with dupilumab at the University Hospital of Zurich were retrospectively evaluated. Disease severity was assessed by bullous pemphigoid disease area index (BPDAI) and pruritus by a numeric rating scale (NRS, 0-10) at baseline; days 1, 3, 14; months 1, 2; and the last follow-up.ResultsA total of 8/12 patients (67%) had complete response, and 4/12 patients (33%) had partial response during dupilumab treatment. Notably, a highly significant reduction of pruritus (p < 0.0001) was observed already on day 1 with further improvement at later time points. Moreover, fast relief of itch could predict treatment response with a significant correlation to clinical response on day 14 (Spearman correlation R 0.70, p value 0.025), with a positive but non-significant trend on day 3 (R 0.63, p value 0.091). Additionally, 92% (11/12 patients) were on dupilumab monotherapy at the last follow-up without any concomitant systemic or topical treatment for BP.ConclusionsThe rapid and significant decline in BP-associated pruritus observed with dupilumab correlated significantly with disease remission. Early evaluation of pruritus response could change how BP is treated in the future and avoid additional immunosuppressive treatment in BP.

Project description:BackgroundBullous pemphigoid (BP) is the most common autoimmune blistering disease in the West. Oral steroids are the standard treatment.This is an update of the review published in 2005.ObjectivesTo assess treatments for bullous pemphigoid.Search strategyIn August 2010 we updated our searches of the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (Clinical Trials), MEDLINE, EMBASE, and the Ongoing Trials registers.Selection criteriaRandomised controlled trials of treatments for participants with immunofluorescence-confirmed bullous pemphigoid.Data collection and analysisAt least two authors evaluated the studies for the inclusion criteria, and extracted data independently.Main resultsWe included 10 randomised controlled trials (with a total of 1049 participants) of moderate to high risk of bias. All studies involved different comparisons, none had a placebo group. In 1 trial plasma exchange plus prednisone gave significantly better disease control at 1 month (0.3 mg/kg: RR 18.78, 95% CI 1.20 to 293.70) than prednisone alone (1.0 mg/kg: RR 1.79, 95% CI 1.11 to 2.90), while another trial showed no difference in disease control at 6 months.No differences in disease control were seen for different doses or formulations of prednisolone (one trial each), for azathioprine plus prednisone compared with prednisone alone (one trial), for prednisolone plus azathioprine compared with prednisolone plus plasma exchange (one trial), for prednisolone plus mycophenolate mofetil or plus azathioprine (one trial), for tetracycline plus nicotinamide compared with prednisolone (one trial). Chinese traditional medicine plus prednisone was not effective in one trial.There were no significant differences in healing in a comparison of a standard regimen of topical steroids (clobetasol) with a milder regimen (RR 1.00, 95% 0.97 to 1.03) in one trial. In another trial, clobetasol showed significantly more disease control than oral prednisolone in people with extensive and moderate disease (RR 1.09, 95% CI 1.02 to 1.17), with significantly reduced mortality and adverse events (RR 1.06, 95% CI 1.00 to 1.12).Authors' conclusionsVery potent topical steroids are effective and safe treatments for BP, but their use in extensive disease may be limited by side-effects and practical factors. Milder regimens (using lower doses of steroids) are safe and effective in moderate BP. Starting doses of prednisolone greater than 0.75 mg/kg/day do not give additional benefit, lower doses may be adequate to control disease and reduce the incidence and severity of adverse reactions. The effectiveness of adding plasma exchange, azathioprine or mycophenolate mofetil to corticosteroids, and combination treatment with tetracycline and nicotinamide needs further investigation.

Project description:Total knee arthroplasty is one of the safest and most routinely performed orthopedic procedures. As the volume of cases is expected to rise each year, so too will the incidence of uncommon complications. We describe a rare case of bullous pemphigoid, an autoimmune skin blistering disorder, that occurred after total knee arthroplasty in an otherwise healthy patient and led to hospital readmission. Early diagnosis and treatment of this condition may limit its spread and help to avoid comorbid sequelae.
