BACKGROUND
Bullous pemphigoid (BP) is the most common autoimmune subepidermal bullous disease of the skin. First-line treatment of systemic corticosteroids may cause serious adverse events. Rituximab, omalizumab, and dupilumab should be explored as alternative treatment options to improve outcomes.
OBJECTIVE
To systematically review the rituximab, omalizumab, and dupilumab treatment outcomes in bullous pemphigoid.
METHODS
A PubMed, Embase, Web of Science, and Cochrane library search were conducted on March 10, 2022. A total of 75 studies were included using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.
RESULTS
Use of rituximab (n=122), omalizumab (n=53) and dupilumab (n=36) were reported in 211 patients with BP. Rituximab led to complete remission in 70.5% (n=86/122) and partial remission in 23.8% (n=29/122) of patients within 5.7 months, with a recurrence rate of 20.5% (n=25/122). 9.0% (n=11/122) of patients died and infection (6.6%, n=8/122) was the most common adverse event. Omalizumab led to complete remission in 67.9% (n=36/53) and partial remission in 20.8% (n=11/53) of patients within 6.6 months, with a recurrence rate of 5.7% (n=3/53). 1.9% (n=1/53) of patients died and thrombocytopenia (1.9%, n=1/53) was observed as the most common adverse event. Dupilumab led to complete remission in 66.7% (n=24/36) and partial remission in 19.4% (n=7/36) of patients within 4.5 months of treatment without any reported adverse events, with a recurrence rate of 5.6% (n=2/36).
CONCLUSIONS
Rituximab, omalizumab, and dupilumab have similar clinical benefits for BP patients. However, rituximab resulted in higher recurrence rates, adverse events, and mortality rates.

Meta-Analysis
BACKGROUND
A growing number of studies have shown encouraging results with omalizumab (OMA) as monotherapy and as an adjunct to oral immunotherapy (OMA+OIT) in patients with single/multiple food allergies.
OBJECTIVES
To evaluate the efficacy and safety of OMA or OMA+OIT in patients with immunoglobulin E (IgE)-mediated food allergy.
METHODS
An extensive literature search (inception to December 31, 2020) was performed to identify randomized, controlled, and observational studies that assessed OMA as monotherapy or OMA+OIT in patients with IgE-mediated food allergy. The outcomes were an increase in tolerated dose of foods, successful desensitization, sustained unresponsiveness, immunological biomarkers, severity of allergic reactions to food, quality of life (QoL), and safety. A P less than .05 was considered significant.
RESULTS
In total, 36 studies were included. The OMA monotherapy (vs pre-OMA) significantly increased the tolerated dose of multiple foods; increased the threshold of tolerated dose for milk, egg, wheat, and baked milk; improved QoL; and reduced food-induced allergic reactions (all P < .01). The OMA+OIT significantly increased the tolerated dose of multiple foods (vs placebo and pre-OMA), desensitization (vs placebo+OIT and pre-OMA) (all P ≤ .01), and improved QoL (vs pre-OMA) and immunoglobulin G4 levels (both P < .01). No major safety concerns were identified.
CONCLUSIONS
In IgE-mediated food allergy, OMA can help patients consume multiple foods and allow for food dose escalation. As an adjunct to OIT, OMA can also support high-dose desensitization and higher maintenance doses. Further studies are warranted to empirically evaluate the effect of OMA and confirm these findings.

Meta-Analysis
Comparative efficacy and safety of monoclonal antibodies and aspirin desensitization for chronic rhinosinusitis with nasal polyposis: A systematic review and network meta-analysis.
BACKGROUND
Chronic rhinosinusitis with nasal polyposis (CRSwNP) is an inflammatory condition of the upper airways. Optimal management is unclear.
OBJECTIVE
We compared the effects of mAbs and aspirin desensitization (ASA-D) for treatment of CRSwNP.
METHODS
We searched the Medline, Embase, Cochrane Central Register of Controlled Trials, International Clinical Trials Registry Platform, US Food and Drug Administration, and the European Medicines Agency databases from inception to August 4, 2021, for randomized controlled trials comparing the effects of mAbs and ASA-D for CRSwNP. We conducted network meta-analysis of sinusitis symptoms, heath-related quality of life, rescue oral corticosteroids and surgery, endoscopic and radiologic scores, and adverse events. We used the Grades of Recommendation Assessment, Development and Evaluation (GRADE) approach to assess certainty of evidence. PROSPERO CRD42020177334.
RESULTS
Twenty-nine randomized controlled trials evaluating 8 treatments (n = 3461) were included in the network meta-analysis. Compared to placebo, moderate to high certainty evidence showed that health-related quality of life (SNOT-22) improved with dupilumab (mean difference [MD] -19.91 [95% confidence interval (CI) -22.50, -17.32]), omalizumab (MD -16.09 [95% CI -19.88, -12.30]), mepolizumab (MD -12.89 [95% CI -16.58, -9.19], ASA-D (MD -10.61 [95% CI -14.51, -6.71]), and benralizumab (MD -7.68 [95% CI -12.09, -3.27]). The risk of rescue nasal polyp surgery likely decreased with dupilumab (risk difference [RD] -16.35% [95% CI -18.13, -13.48]), omalizumab (RD -7.40% [95% CI -11.04, -2.43]), mepolizumab (RD -12.33% [95% CI -15.56, -7.22]), and ASA-D (RD -16.00% [95% CI -19.79, 0.21]; all moderate certainty). Comparisons among agents show with moderate to high certainty that dupilumab ranks among the most beneficial for 7 of 7 outcomes, omalizumab for 2 of 7, mepolizumab for 1 of 7, and ASA-D for 1 of 7.
CONCLUSIONS
Multiple biologics and ASA-D credibly improve patient-important outcomes, with clinically important differences in effects among agents; dupilumab uniquely ranks among the most beneficial for all outcomes studied.

Meta-Analysis
BACKGROUND
This living systematic review is one of several Cochrane Reviews evaluating the medical management of patients with chronic rhinosinusitis. Chronic rhinosinusitis is common. It is characterised by inflammation of the nasal and sinus linings, nasal blockage, rhinorrhoea, facial pressure/pain and loss of sense of smell. It occurs with or without nasal polyps. 'Biologics' are medicinal products produced by a biological process. Monoclonal antibodies are one type, already evaluated in other inflammatory conditions (e.g. asthma and atopic dermatitis).
OBJECTIVES
To assess the effects of biologics for the treatment of chronic rhinosinusitis.
SEARCH METHODS
The Cochrane ENT Information Specialist searched the Cochrane ENT Register; CENTRAL (2020, Issue 9); Ovid MEDLINE; Ovid Embase; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished studies. The date of the search was 28 September 2020.
SELECTION CRITERIA
Randomised controlled trials (RCTs) with at least three months follow-up comparing biologics (monoclonal antibodies) against placebo/no treatment in patients with chronic rhinosinusitis.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methodological procedures. Our primary outcomes were disease-specific health-related quality of life (HRQL), disease severity and serious adverse events (SAEs). The secondary outcomes were avoidance of surgery, extent of disease (measured by endoscopic or computerised tomography (CT) score), generic HRQL and adverse effects (nasopharyngitis, including sore throat). We used GRADE to assess the certainty of the evidence for each outcome.
MAIN RESULTS
We included 10 studies. Of 1262 adult participants, 1260 had severe chronic rhinosinusitis with nasal polyps; 43% to 100% of participants also had asthma. Three biologics, with different targets, were evaluated: dupilumab, mepolizumab and omalizumab. All of the studies were sponsored or supported by industry. For this update (2021) we have included two new studies, including 265 participants, which reported data relating to omalizumab. Anti-IL-4Rα mAb (dupilumab) versus placebo/no treatment (all receiving intranasal steroids) Three studies (784 participants) evaluated dupilumab. Disease-specific HRQL was measured with the SNOT-22 (a 22-item questionnaire, with a score range of 0 to 110; minimal clinically important difference (MCID) 8.9 points). At 24 weeks, dupilumab results in a large reduction (improvement) in the SNOT-22 score (mean difference (MD) -19.61, 95% confidence interval (CI) -22.54 to -16.69; 3 studies; 784 participants; high certainty). At between 16 and 52 weeks of follow-up, dupilumab probably results in a large reduction in disease severity, as measured by a 0- to 10-point visual analogue scale (VAS) (MD -3.00, 95% CI -3.47 to -2.53; 3 studies; 784 participants; moderate certainty). This is a global symptom score, including all aspects of chronic rhinosinusitis symptoms. At between 16 and 52 weeks of follow-up, dupilumab may result in a reduction in serious adverse events compared to placebo (5.9% versus 12.5%, risk ratio (RR) 0.47, 95% CI 0.29 to 0.76; 3 studies, 782 participants; low certainty). Anti-IL-5 mAb (mepolizumab) versus placebo/no treatment (all receiving intranasal steroids) Two studies (137 participants) evaluated mepolizumab. Disease-specific HRQL was measured with the SNOT-22. At 25 weeks, the SNOT-22 score may be reduced (improved) in participants receiving mepolizumab (MD -13.26 points, 95% CI -22.08 to -4.44; 1 study; 105 participants; low certainty; MCID 8.9). It is very uncertain whether there is a difference in disease severity at 25 weeks: on a 0- to 10-point VAS, disease severity was -2.03 lower in those receiving mepolizumab (95% CI -3.65 to -0.41; 1 study; 72 participants; very low certainty). It is very uncertain if there is a difference in the number of serious adverse events at between 25 and 40 weeks (1.4% versus 0%; RR 1.57, 95% CI 0.07 to 35.46; 2 studies; 135 participants, very low certainty). Anti-IgE mAb (omalizumab) versus placebo/no treatment (all receiving intranasal steroids) Five studies (329 participants) evaluated omalizumab. Disease-specific HRQL was measured with the SNOT-22. At 24 weeks omalizumab probably results in a large reduction in SNOT-22 score (MD -15.62, 95% CI -19.79 to -11.45; 2 studies; 265 participants; moderate certainty; MCID 8.9). We did not identify any evidence for overall disease severity. It is very uncertain whether omalizumab affects the number of serious adverse events, with follow-up between 20 and 26 weeks (0.8% versus 2.5%, RR 0.32, 95% CI 0.05 to 2.00; 5 studies; 329 participants; very low certainty).
AUTHORS' CONCLUSIONS
Almost all of the participants in the included studies had nasal polyps (99.8%) and all were using topical nasal steroids for their chronic rhinosinusitis symptoms. In these patients, dupilumab improves disease-specific HRQL compared to placebo. It probably also results in a reduction in disease severity, and may result in a reduction in the number of serious adverse events. Mepolizumab may improve disease-specific HRQL. It is very uncertain if there is a difference in disease severity or the number of serious adverse events. Omalizumab probably improves disease-specific HRQL compared to placebo. It is very uncertain if there is a difference in the number of serious adverse events. There was no evidence regarding the effect of omalizumab on disease severity (using global scores that address all symptoms of chronic rhinosinusitis).

Meta-Analysis
BACKGROUND
Antidrug antibodies (ADAs) may worsen the efficacy and safety of biologics. However, little is known about the incidence of ADAs associated with the 6 biologics approved for the treatment of asthma in the United States.
OBJECTIVE
To elucidate the incidence of ADAs and their impact on reported clinical outcomes.
METHODS
Systematic review and meta-analyses of randomized controlled trials, open-label extension studies, and nonrandomized studies of biologics in patients with asthma indexed in PubMed, Embase, and CENTRAL between January 1, 2000, and July 9, 2022, were carried out. The primary outcomes were treatment-emergent ADAs (incidence) and ADA prevalence.
RESULTS
A total of 46 studies met the eligibility criteria. ADA incidence over follow-up was 2.91% (95% CI, 1.60-4.55) and was highest in the benralizumab studies (8.35%), with a risk ratio of 4.9 (2.69-8.92) when compared with placebo, and lowest in the omalizumab studies (0.00%). Incidence was 7.61% in the dupilumab studies, 4.39% in reslizumab, 3.63% in mepolizumab, and 1.12% in the tezepelumab studies. Incidence of neutralizing antibodies was 0.00% to 10.74% and was highest for benralizumab (7.12%). Incidence of neutralizing antibodies was higher in the benralizumab every 8 weeks (8.17%) versus every 4 weeks arms (5.81%). Results were consistent in subgroup analyses by study type and length of follow-up.
CONCLUSIONS
Approximately 2.9% of individuals in the included studies developed ADAs over study follow-up period. The incidence was highest in the benralizumab group and lowest in the omalizumab group. The subcutaneous route and longer dosing intervals were associated with higher ADA development.

Meta-Analysis
BACKGROUND
An unmet clinical need exists in the management of treatment-refractory allergic bronchopulmonary aspergillosis (ABPA). Omalizumab has shown promising effects in case series and cohort studies; however, evidence to support its routine clinical use is lacking.
OBJECTIVE
The aim of this systematic review and meta-analysis was to evaluate the clinical effectiveness and safety of omalizumab in patients with ABPA.
METHODS
We conducted a systematic search across standard databases using specific key words until May 13, 2021. We performed a meta-analysis to compare the effectiveness (exacerbations, oral corticosteroid [OCS] use, lung function, and patient-reported asthma control) and safety of pre- and post-omalizumab treatment. Subgroup analyses were performed for treatment duration and underlying disease.
RESULTS
In total, 49 studies (n = 267) were included in the qualitative synthesis and 14 case series (n = 186) in the quantitative meta-analysis. Omalizumab treatment significantly reduced the annualized exacerbation rate compared with pretreatment (mean difference, -2.09 [95% CI, -3.07 to -1.11]; P < .01). There was a reduction in OCS use (risk difference, 0.65 [95% CI, 0.46-0.84]; P < .01), an increase in termination of OCS use (risk difference, 0.53 [95% CI, 0.24-0.82]; P < .01), and a reduction in OCS dose (milligrams per day) (mean difference, -14.62 [95% CI, -19.86 to -9.39]; P < .01) in ABPA patients receiving omalizumab. Omalizumab improved FEV % predicted by 11.9% (95% CI, 8.2-15.6; P < .01) and asthma control, and was well-tolerated.
CONCLUSIONS
Omalizumab treatment reduced exacerbations and OCS use, improved lung function and asthma control in patients with ABPA, and was well-tolerated. The results highlight the potential role of omalizumab in the treatment of ABPA.

Meta-Analysis
AIMS
To compare the efficacy of tezepelumab with other approved biologics indirect treatment comparisons (ITCs) in patients aged ≥ 12 years with severe uncontrolled asthma.
MATERIALS AND METHODS
Data from randomized controlled trials (RCTs) identified from a systematic literature review were synthesized using two different ITC approaches: network meta-analysis (NMA) and simulated treatment comparison (STC). Outcomes of interest were annualized asthma exacerbation rate (AAER) and AAER for exacerbations leading to hospitalization. To address potential heterogeneity between study populations, various subgroup analyses were performed for the NMA (based on blood eosinophil count, fractional exhaled nitric oxide level, and presence of allergic asthma), and for the STC, models were adjusted for potential treatment effect modifiers. Sensitivity analyses were performed to assess the impact of study design (exclusion of non-placebo-controlled studies and non-phase 3 or 4 studies). Results were reported as rate ratios (RRs) with 95% credible/confidence intervals and ranking statistics were computed for the NMAs.
RESULTS
Sixteen RCTs were included in at least one of the ITCs. All biologics (tezepelumab, dupilumab, benralizumab, mepolizumab, reslizumab, and omalizumab) had similar efficacy, with no statistically significant RRs for either exacerbation outcome; however, tezepelumab was favorably associated with numerically lower AAERs and was ranked first in the network for both types of exacerbation outcome. This trend was consistent in the subgroup and sensitivity analyses. As with the primary NMA, the STC results did not demonstrate any significant differences between biologics, but point estimates were favorable towards tezepelumab.
LIMITATIONS
Heterogeneity between trials was observed among eligibility criteria and clinically important patient characteristics; however, the impact on findings is expected to be low, based on consistency across analyses.
CONCLUSIONS
Findings from both ITCs (NMA and STC) support the use of tezepelumab in a broad patient population of severe uncontrolled asthma of any phenotype.

Review
BACKGROUND
Anti-glycan antibody serologic markers may serve as a useful adjunct in the diagnosis/prognosis of inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC). This meta-analysis/systemic review aimed to evaluate the diagnostic value, as well as the association of anti-glycan biomarkers with IBD susceptible gene variants, disease complications, and the need for surgery in IBD.
METHODS
The diagnostic odds ratio (DOR), 95% confidence interval (CI), and sensitivity/specificity were used to compare the diagnostic value of individual and combinations of anti-glycan markers and their association with disease course (complication and/or need for surgery).
RESULTS
Fourteen studies were included in the systemic review and nine in the meta-analysis. Individually, anti-Saccharomyces cervisiae antibodies (ASCA) had the highest DOR for differentiating IBD from healthy (DOR 21.1; 1.8-247.3; two studies), and CD from UC (DOR 10.2; CI 7.7-13.7; seven studies). For combination of ≥2 markers, the DOR was 2.8 (CI 2.2-3.6; two studies) for CD-related surgery, higher than any individual marker, while the DOR for differentiating CD from UC was 10.2 (CI 5.6-18.5; three studies) and for complication was 2.8 (CI 2.2-3.7; two studies), similar to individual markers.
CONCLUSIONS
ASCA had the highest diagnostic value among individual anti-glycan markers. While anti-chitobioside carbohydrate antibody (ACCA) had the highest association with complications, ASCA and ACCA associated equally with the need for surgery. Although in most individual studies the combination of ≥2 markers had a better diagnostic value as well as higher association with complications and need for surgery, we found the combination performing slightly better than any individual marker in our meta-analysis.

Review
INTRODUCTION
About 10% of adults have suffered an attack of asthma, and up to 5% of these have severe disease that responds poorly to treatment. Patients with severe disease have an increased risk of death, but patients with mild-to-moderate disease are also at risk of exacerbations. Most guidelines about the management of asthma follow stepwise protocols. This review does not endorse or follow any particular protocol, but presents the evidence about specific interventions.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for chronic asthma? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 54 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: adding anti-IgE treatment; beta(2) agonists (adding long-acting inhaled beta(2) agonists when asthma is poorly controlled by inhaled corticosteroids, or short-acting inhaled beta(2) agonists as needed for symptom relief); inhaled corticosteroids (low dose and increasing dose); leukotriene antagonists (with or without inhaled corticosteroids); and theophylline (when poorly controlled by inhaled corticosteroids).

Review
BACKGROUND
Several options are available for the treatment of chronic rhinosinusitis (CRS), but disease control remains elusive for many patients. Recently, literature has emerged describing anti-IgE monoclonal antibody as a potential therapy for CRS. However, its effectiveness and safety are not well known. The purpose of this systematic review was to assess the effectiveness and safety of anti-IgE therapy and to identify evidence gaps that will guide future research for the management of CRS.
METHODS
Methodology was registered with PROSPERO (No. CRD42014007600). A comprehensive search was performed of standard bibliographic databases, Google Scholar, and clinical trials registries. Only randomized controlled trials assessing anti-IgE therapy in adult patients for the treatment of CRS were included. Two independent reviewers extracted data using a pre-defined extraction form and performed quality assessment using the Cochrane risk of bias tool and the GRADE framework.
RESULTS
Two studies met our inclusion criteria. When comparing anti-IgE therapy to placebo, there was a significant difference in Lund-McKay score (p = 0.04) while no difference was seen for percent opacification on computed tomography (CT). At 16 weeks, treatment led to a decrease in clinical polyp score. No significant difference was seen with regard to quality of life (Total Nasal Symptom Severity (TNSS), p < 0.21; Sinonasal Outcome Test 20 (SNOT-20), p < 0.60), and no serious complications were reported in either trial. Based on the quality assessment, studies were deemed to be of moderate risk of bias and a low overall quality of evidence.
CONCLUSIONS
There is currently insufficient evidence to determine the effectiveness of anti-IgE monoclonal antibody therapy for the treatment of CRS.
