Abstract
BACKGROUND Treatment of allergic bronchopulmonary aspergillosis (ABPA) is challenging. Biological therapies have been reported as adjunctive treatments for ABPA, primarily in case series or case reports. This study aimed to analyze the efficacy of biologics for managing ABPA both qualitatively and quantitatively. METHODS All articles on APBA published in October 2023 were searched in PubMed, Web of Science, ClinicalTrials.gov, and Embase databases. The effects of interest were the mean changes from baseline for outcomes, including exacerbation rates, oral corticosteroids usage (OCS), and total immunoglobulin E (IgE) levels. Reported outcomes were quantitatively synthesized by usual or individual patient data (IPD) meta-analyses. PROSPERO registration number: CRD42022373396. RESULTS A total of 86 studies were included in the systematic review including 346 patients. Sixteen studies on omalizumab were pooled for the usual meta-analysis. Omalizumab therapy significantly reduced exacerbation rates (- 2.29 [95%CI - 3.32, - 1.26]), OCS dosage (- 10.91 mg [95%CI - 18.98, - 2.85]), and total IgE levels (- 273.07 IU/mL [95%CI - 379.30, - 166.84]), meanwhile improving FEV1% predicted (10.09% [95%CI 6.62, 13.55]). Thirty-one studies on dupilumab, mepolizumab, or benralizumab were pooled to perform an IPD meta-analysis, retrospectively. Both dupilumab and mepolizumab significantly reduced exacerbation rates, OCS, and total IgE levels. Benralizumab showed a similar trend, but it was not statistically significant. Tezepelumab showed weak evidence of its effects on ABPA. All five biologics led to milder clinical symptoms (e.g., cough, wheezing) with serious adverse effects that happened once in omalizumab treatment. CONCLUSION These results indicate the clinical benefit of omalizumab, dupilumab, and mepolizumab in patients with ABPA. Further randomized, controlled studies with a larger sample size and longer follow-up are needed to confirm these findings.

THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2023; 11:896-905. [PMID: 36581073 DOI: 10.1016/j.jaip.2022.12.012] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Revised: 12/09/2022] [Accepted: 12/12/2022] [Indexed: 12/28/2022]
Abstract
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 FEV1 % 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.

Abstract
BACKGROUND Aspergillus fumigatus is a common saprophytic fungus causing allergic bronchopulmonary aspergillosis (ABPA) in patients with cystic fibrosis (CF). The recommended first-line treatment for ABPA is oral steroids, followed by antifungal therapy. However, both treatments are not free from adverse effects; thus, efforts are being made to identify new drugs showing the same effectiveness but with fewer or no side-effects. Therein, biologic drugs have been significantly implemented in clinical practice in treating ABPA in patients with CF. OBJECTIVE To systematically review the available literature, providing evidence for the administration of biologic drugs as a new potential treatment of ABPA in both the paediatric and adult populations with CF. METHODS A systematic review of the literature published between January 2007 and July 2021 was performed, using a protocol registered with the International Prospective Register of Systematic Reviews (PROSPERO CRD42021270932). RESULTS A total of 21 studies focusing on the use of biologics in treating ABPA in CF patients was included. We highlighted a paucity of data providing evidence for biologic drug use in ABPA. CONCLUSION Scientific evidence is insufficient to support firm conclusions and randomised clinical trials are urgently required to investigate the efficacy and safety of biologics for ABPA in CF patients.

Abstract
In recent years, off-label and unlicensed drug use has extensively developed in the paediatric population. For a long time, clinical trials in the paediatric population were considered complicated to perform because of ethical problems, causing frequent off-label use. Off-label drug use remains an important public health issue, especially for children with rare conditions or with diseases not responsive to conventional treatments. The present paper is a narrative review of the literature of off-label drug use in children. The aim of our study is to summarize the main works dealing with the off-label use of biological drugs in paediatrics. Further studies analyzing their efficacy, safety, and cost-benefit ratios are needed to extend the use of biological therapies to the paediatric population.

Abstract
OBJECTIVE To review the available literature addressing alternative allergic bronchopulmonary aspergillosis (ABPA) treatment options for patients with cystic fibrosis (CF). DATA SOURCES A literature search of PubMed was performed (January 2002 to April 2021) using the following search terms: allergic bronchopulmonary aspergillosis, aspergillus-related lung disease, cystic fibrosis. Manufacturer prescribing information, clinical practice guidelines, and data from ClinicalTrials.gov were incorporated in the reviewed data. STUDY SELECTION AND DATA EXTRACTION Relevant English-language studies or those conducted in humans were considered for inclusion. DATA SYNTHESIS Available literature for alternative ABPA treatments in CF is lacking randomized controlled trials, but there is considerable support in case reports and case series describing the benefits in pediatric and adult patients. Recent literature has begun to explore the place in therapy for novel, corticosteroid-sparing treatment approaches. The alternative therapies summarized in this review all resulted in clinical improvement and subsequent discontinuation or dose reductions of oral corticosteroids, with minimal reported adverse drug effects. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE Although corticosteroids are the cornerstone of ABPA management, the toxicities can be significant limitations in an already high-risk patient population. Patients may fail or become intolerant to guideline-recommended therapies and require alternative treatment approaches. CONCLUSIONS Alternative treatment modalities for ABPA in patients with CF, including azole antifungals, pulsed intravenous glucocorticoids, omalizumab, mepolizumab, and inhaled amphotericin, appear to be efficacious and well tolerated. Pharmacological properties including route of administration, storage and stability, beyond use dating, and adverse effects of the various treatment modalities must be considered when selecting a practical care plan for patients.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is a complex pulmonary disorder characterized by a hypersensitivity reaction to Aspergillus fumigatus, and almost always seen in patients with cystic fibrosis (CF) and asthma. Fungal hyphae leads to an ongoing inflammation in the airways that may result in bronchiectasis, fibrosis, and eventually loss of lung function. Despite the fact that ABPA is thought to be more prevalent in CF than in asthma, the literature on ABPA in CF is more limited. The diagnosis is challenging and may be delayed because it is made based on a combination of clinical features, and radiologic and immunologic findings. With clinical deterioration of a patient with CF, ABPA is important to be kept in mind because clinical manifestations mimic pulmonary exacerbations of CF. Early diagnosis and appropriate treatment are important in preventing complications related to ABPA. Treatment modalities involve the use of anti-inflammatory agents to suppress the immune hyperreactivity and the use of antifungal agents to reduce fungal burden. Recently, in an effort to treat refractory patients or to reduce adverse effects of steroids, other treatment options such as monoclonal antibodies have started to be used. Intensive research of these new agents in the treatment of children is being conducted to address insufficient data.

Abstract
CFTR protein malfunction results in thick, copious mucus, causes poor mucociliary clearance and, ultimately, structural lung damage such as bronchiectasis. All of these manifestations of cystic fibrosis contribute to a rich milieu for lower respiratory pathogens in patients affected by the disease. CF patients are, therefore, highly susceptible to chronic colonization with many pathogens such as Staphylococcus aureus and Pseudomonas aeruginosa. They are also uniquely prone to acute infections with respiratory pathogens, which tend to persist longer and cause more impairment in lung function than in patients without CF. Tailored strategies for managing infectious complications of CF patients include chronic prophylactic antibiotics, use of systemic as well as inhaled antibiotics, mechanical assistance with mucus clearance, and scrupulous infection control measures.

Abstract
Histamine-1 receptor (H1R) belongs to the family of rhodopsin-like G-protein-coupled receptors expressed in cells that mediates allergies and other pathophysiological diseases. For alleviation of allergic symptoms, H1R antagonists are therapeutic drugs; of which the most frequently prescribed are second generation drugs, such as; Cetirizine, Loratadine, Hydroxyzine, Desloratadine, Bepotastine, Acrivastine and Rupatadine. To understand their potency, binding affinity and interaction; we have employed molecular docking and quantum chemical study such as; Induced-fit docking and calculation of quantum chemical descriptors. This study also introduces the binding site characterization of H1R, with its known antagonists and Curcumin (our proposed alternative H1R antagonist); useful for future drug target site. The interactive binding site residues of H1R are found to be; Lys-191, Tyr-108, Asp-107, Tyr-100, Lys-179, Lys-191, Thr-194, Trp-428, Phe-432, Tyr-458, Hie-450, with most of these shown to be inhibited by naturally-occurring compound curcumin. Amongst the FDA approved drugs, Hydroxyzine showed best ligand binding affinity, calculated as - 141.491 kcal/mol and naturally occurring compound, Curcumin showed binding affinity of - 87.046 kcal/mol. The known antagonists of H1R has been used for hypothesizing curcumin as naturally occurring lead compound for the target using accurate molecular docking simulation study. Though the pharmacological action of known inhibitor is already established, they could differ from their reactivity, which we have also focused in our study for predicting drug reactivity.

Abstract
Background Allergic bronchopulmonary aspergillosis (ABPA) is a condition characterized by a Th2 response, serum eosinophilia, and increased total serum IgE to Aspergillus fumigatus. ABPA occurs in cystic fibrosis (CF) and asthma. Omalizumab is a humanized recombinant monoclonal antibody against IgE. Previous studies reported borderline results when treating ABPA with omalizumab. Methods A retrospective study to investigate the efficacy of omalizumab in the treatment of ABPA in CF patients was conducted at 3 CF centers in Israel and Belgium. Data were obtained from the digital archive. We measured 4 outcome parameters: forced expiratory volume in 1 second, body mass index, pulmonary exacerbations, and steroid sparing. Results The database was composed on the records of 9 patients. None of the outcome parameters showed any improvement. A favorable outcome was observed in patients with higher levels of posttreatment total IgE than those with lower levels. CF-related diabetes and male gender showed trends for poorer outcomes. Conclusion No benefits were detected on treating ABPA in CF with omlaizumb. Monitoring the total IgE was not helpful. A prospective randomized double-blind study is needed.

Abstract
Cystic fibrosis (CF) is an autosomal recessive genetic disorder characterized by dysfunction of the CFTR gene. It is a multisystem disease that most often affects White individuals. In recent decades, various advances in the diagnosis and treatment of CF have drastically changed the scenario, resulting in a significant increase in survival and quality of life. In Brazil, the current neonatal screening program for CF has broad coverage, and most of the Brazilian states have referral centers for the follow-up of individuals with the disease. Previously, CF was limited to the pediatric age group. However, an increase in the number of adult CF patients has been observed, because of the greater number of individuals being diagnosed with atypical forms (with milder phenotypic expression) and because of the increase in life expectancy provided by the new treatments. However, there is still great heterogeneity among the different regions of Brazil in terms of the access of CF patients to diagnostic and therapeutic methods. The objective of these guidelines was to aggregate the main scientific evidence to guide the management of these patients. A group of 18 CF specialists devised 82 relevant clinical questions, divided into five categories: characteristics of a referral center; diagnosis; treatment of respiratory disease; gastrointestinal and nutritional treatment; and other aspects. Various professionals working in the area of CF in Brazil were invited to answer the questions devised by the coordinators. We used the PubMed database to search the available literature based on keywords, in order to find the best answers to these questions.

Abstract
Chronic airway infection plays an essential role in the progress of cystic fibrosis (CF) lung disease. In the past decades, mainly bacterial pathogens, such as Pseudomonas aeruginosa, have been the focus of researchers and clinicians. However, fungi are frequently detected in CF airways and there is an increasing body of evidence that fungal pathogens might play a role in CF lung disease. Several studies have shown an association of fungi, particularly Aspergillus fumigatus and Candida albicans, with the course of lung disease in CF patients. Mechanistically, in vitro and in vivo studies suggest that an impaired immune response to fungal pathogens in CF airways renders them more susceptible to fungi. However, it remains elusive whether fungi are actively involved in CF lung disease pathologies or whether they rather reflect a dysregulated airway colonization and act as microbial bystanders. A key issue for dissecting the role of fungi in CF lung disease is the distinction of dynamic fungal-host interaction entities, namely colonization, sensitization or infection. This review summarizes key findings on pathophysiological mechanisms and the clinical impact of fungi in CF lung disease.

Abstract
Fungal infections cause morbidity worldwide and are associated with an unacceptably high mortality despite the availability of antifungal drugs. The incidence of mycoses is rising because of the HIV pandemic and because immunomodulatory drugs are increasingly used to treat autoimmune diseases and cancer. New classes of antifungal drugs have only been partly successful in improving the prognosis for patients with fungal infection. Adjunctive host-directed therapy is therefore believed to be the only option to further improve patient outcomes. Recent advances in the understanding of complex interactions between fungi and host have led to the design and exploration of novel therapeutic strategies in cytokine therapy, vaccines, and cellular immunotherapy, each of which might become viable adjuncts to existing antifungal regimens. In this report, we discuss immunotherapeutic approaches-the rationale behind their design, the challenges in their use, and the progress that is so urgently needed to overcome the devastating effect of fungal diseases.

Abstract
This review outlines a new, personalized approach for the classification and management of airway diseases. The current approach to airways disease is, we believe, no longer fit for purpose. It is impractical, overgeneralizes complex and heterogeneous conditions and results in management that is imprecise and outcomes that are worse than they could be. Importantly, the assumptions we make when applying a diagnostic label have impeded new drug discovery and will continue to do so unless we change our approach. This review suggests a new mechanism-based approach where the emphasis is on identification of key causal mechanisms and targeted intervention with treatment based on possession of the relevant mechanism rather than an arbitrary label. We highlight several treatable traits and suggest how they can be identified and managed in different healthcare settings.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) affects up to 15% of patients with cystic fibrosis (CF). Corticosteroids are used as first-line therapy, but relapse and adverse effects commonly occur. Case reports have suggested the efficacy of the anti-IgE recombinant humanized monoclonal antibody omalizumab. A retrospective multicenter observational French study retrieved 32 CF patients (11 children and 21 adults) who have received omalizumab for more than 3 months in the context of ABPA. Clinical characteristics, concomitant medications (inhaled and oral corticosteroids, antifungal drugs), lung function, body mass index (BMI), and serum IgE were compared at the start and during the first year of omalizumab therapy. Omalizumab-related adverse effects and costs were also evaluated. No significant difference with omalizumab could be demonstrated with regard to lung function, BMI, or the number of patients receiving oral corticosteroids. At the time of initiation of omalizumab, 56% of patients were receiving oral corticosteroids. Five patients were able to discontinue corticosteroids during follow-up and nine patients were able to reduce their daily dose. A total of 78% of the patients had received antifungal therapy at the time of the initiation of omalizumab. Treatment tolerance was good (12.5% of patients experienced side effects). The median cost of omalizumab treatment was €3,620 per patient per month. Omalizumab may represent a steroid-sparing therapy in CF patients with ABPA. A randomized-controlled trial is urgently required to provide higher level of evidence regarding the efficacy and cost-effectiveness of omalizumab in CF patients with ABPA.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is a pulmonary disorder that often occurs in patients with asthma or cystic fibrosis (CF) and is characterized by a hypersensitivity response to the allergens of the fungus Aspergillus fumigatus. In patients with CF, growth of A. fumigatus hyphae within the bronchial lumen triggers an immunoglobulin E (IgE)-mediated hypersensitivity response that results in airway inflammation, bronchospasm, and bronchiectasis. In most published studies, the prevalence of ABPA is about 8.9% in patients with CF. Since the clinical features of this condition overlap significantly with that of CF, ABPA is challenging to diagnose and remains underdiagnosed in many patients. Diagnosis of ABPA in CF patients should be sought in those with evidence of clinical and radiologic deterioration that is not attributable to another etiology, a markedly elevated total serum IgE level (while off steroid therapy) and evidence of A. fumigatus sensitization. Management of ABPA involves the use of systemic steroids to reduce inflammation and modulate the immune response. In patients who do not respond to steroids or cannot tolerate them, antifungal agents should be used to reduce the burden of A. fumigatus allergens. Recent studies suggest that omalizumab may be an effective option to reduce the frequency of ABPA exacerbations in patients with CF. Further randomized controlled trials are needed to better establish the efficacy of omalizumab in managing patients with CF and ABPA.

Abstract
Omalizumab, a humanized mAb that binds to IgE, has been an effective therapy for patients with severe allergic asthma; however, there are few clinical trials examining the efficacy of Omalizumab in patients with allergic bronchopulmonary aspergillosis (ABPA) except some case reports. To assess the clinical and immunological effects of Omalizumab in ABPA patients, we made a synthesis review of 102 cases from 30 published literature, analyzed the effects of Omalizumab therapy in ABPA and conducted subgroup analyses to determine factors that influenced the therapy endpoints. We found that Omalizumab treatment not only provided a clinically important reduction in serum IgE, exacerbation rates and steroid requirement, but also showed attenuated asthma symptoms and improved pulmonary function parameters in patients with ABPA. Moreover, further discussion was made when interpretating the results. Double-blind, randomized, placebo-controlled trials are necessary to establish the efficacy and safety of this novel therapeutic intervention for ABPA patients.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA), a progressive fungal allergic lung disease, is a common complication of asthma or cystic fibrosis. Although ABPA has been recognized since the 1950s, recent research has underscored the importance of Th2 immune deviation and granulocyte activation in its pathogenesis. There is also strong evidence of widespread under-diagnosis due to the complexity and lack of standardization of diagnostic criteria. Treatment has long focused on downregulation of the inflammatory response with prolonged courses of oral glucocorticosteroids, but more recently concerns with steroid toxicity and availability of new treatment modalities has led to trials of oral azoles, inhaled amphotericin, pulse intravenous steroids, and subcutaneously-injected anti-IgE monoclonal antibody omalizumab, all of which show evidence of efficacy and reduced toxicity.

Abstract
BACKGROUND Allergic bronchopulmonary aspergillosis (ABPA) in cystic fibrosis (CF) is characterized by destructive changes in the airways. Long-term treatment with oral corticosteroids is often required for repeated exacerbations. Because elevated total IgE is a cardinal abnormality of ABPA, omalizumab has been used sporadically to decrease corticosteroid dose or totally replace corticosteroids. OBJECTIVE The aim of this report is to describe our experience with omalizumab treatment in patients with CF and ABPA. METHODS We conducted a review of 6 CF patients with ABPA receiving omalizumab. All patients were treated with oral prednisolone and itraconazole. Omalizumab was started if the patient was not responding to steroid treatment, which was determined according to serum IgE levels and/or clinical findings or depending on if there were side effects caused by steroid treatment. RESULTS The mean age of patients at the beginning of omalizumab treatment was 16.1 years. One patient had a new diagnosis of ABPA; however, the others had the first to third exacerbation when treated with omalizumab. The mean duration of ABPA by the time that treatment with omalizumab started was 13 ± 12.4 months (range = 2-29 months). With omalizumab treatment, IgE levels were decreased in all patients, and Aspergillus-specific IgE levels were decreased in 4 patients; however, FEV1(% predicted) improved only in 2 patients who had mild disease. Corticosteroids were reduced in the first, second, and third months of omalizumab treatment in 2, 1, and 3 patients, respectively. In 2 patients, steroid treatment was stopped. None of the patients suffered from side effects of omalizumab. The mean duration of omalizumab treatment was 12.5 months (range = 6-18 months). CONCLUSIONS This study showed steroid-sparing effect, decreasing IgE levels, and improvement in respiratory symptoms in 6 CF patients with omalizumab treatment. Although this is a small sample of the population, omalizumab may be an alternative therapy for ABPA in CF patients who fail to respond to systemic corticosteroids or have serious adverse effects.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Turmeric (Curcuma longa) has traditionally been used to treat pain, fever, allergic and inflammatory diseases such as bronchitis, arthritis, and dermatitis. In particular, turmeric and its active component, curcumin, were effective in ameliorating immune disorders including allergies. However, the effects of turmeric and curcumin have not yet been tested on food allergies. MATERIALS AND METHODS Mice were immunized with intraperitoneal ovalbumin (OVA) and alum. The mice were orally challenged with 50mg OVA, and treated with turmeric extract (100mg/kg), curcumin (3mg/kg or 30 mg/kg) for 16 days. Food allergy symptoms including decreased rectal temperature, diarrhea, and anaphylaxis were evaluated. In addition, cytokines, immunoglobulins, and mouse mast cell protease-1 (mMCP-1) were evaluated using ELISA. RESULTS Turmeric significantly attenuated food allergy symptoms (decreased rectal temperature and anaphylactic response) induced by OVA, but curcumin showed weak improvement. Turmeric also inhibited IgE, IgG1, and mMCP-1 levels increased by OVA. Turmeric reduced type 2 helper cell (Th2)-related cytokines and enhanced a Th1-related cytokine. Turmeric ameliorated OVA-induced food allergy by maintaining Th1/Th2 balance. Furthermore, turmeric was confirmed anti-allergic effect through promoting Th1 responses on Th2-dominant immune responses in immunized mice. CONCLUSION Turmeric significantly ameliorated food allergic symptoms in a mouse model of food allergy. The turmeric as an anti-allergic agent showed immune regulatory effects through maintaining Th1/Th2 immune balance, whereas curcumin appeared immune suppressive effects. Therefore, we suggest that administration of turmeric including various components may be useful to ameliorate Th2-mediated allergic disorders such as food allergy, atopic dermatitis, and asthma.

Pattern recognition pathways leading to a Th2 cytokine bias in allergic bronchopulmonary aspergillosis patients. Clin Exp Allergy 2015; 45:423-37. [PMID: 24912986 DOI: 10.1111/cea.12354] [Citation(s) in RCA: 55] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2013] [Revised: 04/23/2014] [Accepted: 06/02/2014] [Indexed: 11/30/2022]
Abstract
BACKGROUND Allergic bronchopulmonary aspergillosis (ABPA) is characterised by an exaggerated Th2 response to Aspergillus fumigatus, but the immunological pathways responsible for this effect are unknown. OBJECTIVE The aim of this study was to decipher the pattern recognition receptors (PRRs) and cytokines involved in the Aspergillus-specific Th2 response and to study Aspergillus-induced responses in healthy controls and ABPA patients. METHODS Peripheral blood mononuclear cells (PBMCs) were stimulated with heat-killed Aspergillus conidia, various other pathogens, or PRR ligands. PRRs and cytokine pathways were blocked with PRR-blocking reagents, anti-TNF (Etanercept or Adalimumab), IL-1Ra (Anakinra) or IFNγ (IFN-gamma). ELISA and FACS were used to analyse cytokine responses. RESULTS Aspergillus was the only pathogen that stimulated the Th2 cytokines IL-5 and IL-13, while Gram-negative bacteria, Gram-positive bacteria, Candida albicans, chitin, β-glucan or Toll-like receptor (TLR) ligands did not. Depletion of CD4(+) cells abolished IL-13 production. Blocking complement receptor 3 (CR3) significantly reduced IL-5 and IL-13, while blocking TLR2, TLR4 or dectin-1 had no effect. ABPA patients displayed increased Aspergillus-induced IL-5 and IL-13 and decreased IFNγ production compared with healthy controls. All biological agents tested showed the capability to inhibit Th2 responses, but also decreased Aspergillus-induced IFNγ. CONCLUSIONS AND CLINICAL RELEVANCE Aspergillus conidia are unique in triggering Th2 responses in human PBMCs, through a CR3-dependent pathway. ABPA patients display a significantly increased Aspergillus-induced Th2/Th1 ratio that can be modulated by biologicals. These data provide a rationale to explore IFNγ therapy in ABPA as a corticosteroid-sparing treatment option, by dampening Th2 responses and supplementing the IFNγ deficiency at the same time.

Abstract
Biologic agents (also termed biologicals or biologics) are therapeutics that are synthesized by living organisms and directed against a specific determinant, for example, a cytokine or receptor. In inflammatory and autoimmune diseases, biologicals have revolutionized the treatment of several immune-mediated disorders. Biologicals have also been tested in allergic disorders. These include agents targeting IgE; T helper 2 (Th2)-type and Th2-promoting cytokines, including interleukin-4 (IL-4), IL-5, IL-9, IL-13, IL-31, and thymic stromal lymphopoietin (TSLP); pro-inflammatory cytokines, such as IL-1β, IL-12, IL-17A, IL-17F, IL-23, and tumor necrosis factor (TNF); chemokine receptor CCR4; and lymphocyte surface and adhesion molecules, including CD2, CD11a, CD20, CD25, CD52, and OX40 ligand. In this task force paper of the Interest Group on Biologicals of the European Academy of Allergy and Clinical Immunology, we review biologicals that are currently available or tested for the use in various allergic and urticarial pathologies, by providing an overview on their state of development, area of use, adverse events, and future research directions.

Abstract
OBJECTIVE To provide an overview of primary and secondary mechanisms associated with anti-IgE therapy and their relation to other potential indications in diseases affecting the respiratory tract. DATA SOURCES Literature from PubMed searches for publications providing insight into secondary mechanisms resulting from anti-IgE therapy and publications reporting on the use of omalizumab to treat conditions that affect the respiratory tract, other than severe atopic asthma. STUDY SELECTIONS Clinical trials or case reports were identified for asthma in patients without atopy, allergic rhinitis, nasal polyposis, and allergic bronchopulmonary aspergillosis. RESULTS There is substantial evidence from controlled trials supporting a benefit for allergic rhinitis. Case reports and series on more than 50 patients with allergic bronchopulmonary aspergillosis have been published, including patients with or without cystic fibrosis; most have reported benefits in terms of decreased steroid use, exacerbation rates, and, in patients with cystic fibrosis, improvement in lung function. Several small controlled studies on nasal polyposis have shown equivocal results. One small controlled trial in patients with nonatopic asthma showed a significant improvement for lung function but not in exacerbation rate or asthma scores. CONCLUSION Recent insight into the immunopathology of respiratory diseases should be used to identify patient populations likely to respond to anti-IgE therapy. Controlled clinical trials are needed to confirm efficacy and determine the clinical significance of the effects of omalizumab in these populations.

Abstract
BACKGROUND Allergic bronchopulmonary aspergillosis (ABPA) is a severe complication in patients with cystic fibrosis (CF), resulting in deterioration of lung function and impairment of overall prognosis. Standard therapy consists of high dosage, long-term corticosteroid treatment. This carries the risk of serious side effects such as immune suppression, diabetes and osteoporosis. Antifungal drugs such as itraconazole may cause interactions with other drugs and drug levels need to be monitored. Omalizumab treatment has been tried in several case studies. METHODS This was a retrospective study of six patients (four female, two male, age 4-33 years old) with CF and ABPA treated with omalizumab within an observation period of 7.5 years. RESULTS All patients showed clinical and laboratory stability or even an improvement within the treatment and post-treatment observation period, although omalizumab therapy was less effective in patients with progressed lung disease and long-term ABPA. Side effects of systemic steroids were reduced. CONCLUSION Omalizumab has the potential to be an additional and solitary treatment option in patients with CF and ABPA. Early onset treatment may be beneficial and patients with early stage of lung disease seem to benefit more.

Abstract
IgE is central to the pathophysiology of allergic asthma. Omalizumab, a humanized anti-IgE mAb, specifically binds free IgE and interrupts the allergic cascade by preventing binding of IgE with its high-affinity FcεRI receptors on mast cells, antigen-presenting cells, and other inflammatory cells. The clinical efficacy of omalizumab has been well documented in a number of clinical trials that involve adults, adolescents, and children with moderate-to-severe and severe allergic asthma. In these studies, omalizumab reduced exacerbations, asthma symptoms, inhaled corticosteroid and rescue medication use, and improved quality of life relative to placebo or best standard of care. Similar benefits have been reported in observational studies in "real-world" populations of patients. Results from recent pooled data from randomized clinical trials and from a large prospective cohort study provide reassurance about the long-term safety of omalizumab. Omalizumab dosing is individualized according to body weight and serum-IgE level, and recent adjustments to the dosing algorithm in Europe have enabled more patients to be eligible for treatment. Ongoing and future research is investigating the optimal duration of therapy, accurate predictors of response to treatment, and efficacy in nonatopic asthma as well as other IgE-mediated conditions.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is a complex pulmonary disorder caused by immunologic reactions to antigens released by Aspergillus fumigatus, a ubiquitous fungi colonizing the tracheobronchial tree of asthmatic patients. The clinical presentation is usually poorly controlled asthma, recurrent pulmonary opacities and bronchiectasis. The prevalence of ABPA in asthma clinics may be as high as 13% with a global burden of almost 5 million patients. A. fumigatus-specific IgE level is the most sensitive test in diagnosis of ABPA, and all asthmatic patients should be routinely screened with A. fumigatus-specific IgE levels for early diagnosis. The goals of managing ABPA include control of asthma, prevention and treatment of acute exacerbations, and preventing the development or progression of bronchiectasis. Glucocorticoids are the treatment of choice with itraconazole reserved for those with recurrent exacerbations and glucocorticoid-dependent disease. There is a dire need for newer treatment approaches including oral antifungal agents and immunomodulatory therapy.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) complicating cystic fibrosis (CF) is treated with corticosteroids. Since elevated IgE is a cardinal abnormality, anti-IgE has been used sporadically as adjuvant treatment. In eight case reports, 13 children with CF and ABPA received anti-IgE resulting in improved FEV1 , fewer respiratory symptoms and decreased corticosteroid use.

Abstract
A large number of trials show that the anti-immunoglobulin (Ig) E antibody omalizumab is very effective in patients with severe allergic asthma. This is acknowledged in consensus documents. The drug also has a good safety profile and a pharmacoeconomic advantage due to a reduction in the number of hospitalizations for asthma attacks. In recent years, some studies have shown that omalizumab is effective also in nonallergic asthma. Effects on the complex signaling mechanisms leading to activation of effector cells and to mediator release may account for this outcome. Indeed, omalizumab has been reported to be effective in a number of IgE-mediated and non-IgE-mediated disorders. Concerning the former, clinical efficacy has been observed in rhinitis, allergic bronchopulmonary aspergillosis, latex allergy, atopic dermatitis, allergic urticaria, and anaphylaxis. In addition, omalizumab has been demonstrated to be able to prevent systemic reactions to allergen immunotherapy, thus enabling completion of treatment in patients who otherwise would have to stop it. Concerning non-IgE-mediated disorders, omalizumab has been reported to be effective in nasal polyposis, autoimmune urticaria, chronic idiopathic urticaria, physical urticaria, idiopathic angioedema, and mastocytosis. Current indications for treatment with omalizumab are confined to severe allergic asthma. Consequently, any other prescription can only be off-label. However, it is reasonable to expect that the use of omalizumab will be approved for particularly important indications, such as anaphylaxis, in the near future.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is a severe type of asthma. Some cases are resistant to treatment, even with regular use of antiasthmatic drugs and antifungal agents. The diagnosis of ABPA was made in a 40-year-old patient with ABPA according to the Rosenberg-Patterson criteria. Symptoms were not controlled despite regular use of antiasthmatic drugs, daily systemic steroids, and antifungal agents. Omalizumab, administered in an attempt to stabilize these uncontrolled symptoms, was effective with no adverse events. Our experience suggests omalizumab is a potential candidate drug for controlling steroid-dependent ABPA.
