Abstract
At the end of December 2019, a novel coronavirus, the severe acute respiratory syndrome coronavirus 2, caused an outbreak of pneumonia spreading from Wuhan, Hubei province, to the whole country of China and then the entire world, forcing the World Health Organization to make the assessment that the coronavirus disease (COVID-19) can be characterized as a pandemic, the first ever caused by a coronavirus. To date, clinical evidence and guidelines based on reliable data and randomized clinical trials for the treatment of COVID-19 are lacking. In the absence of definitive management protocols, many treatments for COVID-19 are currently being evaluated and tested worldwide. Some of these options were soon abandoned due to ineffectiveness, while others showed promising results. The basic treatments are mainly represented by antiviral drugs, even if the evidence is not satisfactory. Among the antivirals, the most promising appears to be remdesivir. Corticosteroids and tocilizumab seem to guarantee positive results in selected patients so far, although the timing of starting therapy and the most appropriate therapeutic schemes remain to be clarified. Efficacy of the other drugs is still uncertain, and they are currently used as a cocktail of treatments in the absence of definitive guidelines. What will represent the real solution to the enormous problem taking place worldwide is the identification of a safe and effective vaccine, for which enormous efforts and investments are underway.

Abstract
Introduction: The development of biologic molecules led to a drastic change in the therapeutic approach to asthma. With the prospect of acting on different pathophysiological mechanisms of the disease, the idea of precision medicine was developed, in which a single molecule is able to modify a specific triggering mechanism. Thus, it seemed limiting to stop at the distinction of patients phenotypes and the concept of endotypes became more relevant in the therapeutic approach.Areas covered: This review deepened the topic of precision medicine through the transition from phenotyping to endotyping. We performed a review of the literature, preferring articles quoted in Medline and published in journals with an impact factor. Results showed that it is fundamental to take into consideration the role of biomarkers and the related therapies currently available for precision medicine.Expert opinion: The possible overlap of patients in different phenotypes requires a more precise classification, which considers endotypization. With the development of biological drugs able to modify and modulate some pathophysiological mechanisms of the disease, the theoretical concept of endotyping becomes practical, allowing the clinician to choose the specific mechanism to 'attack' in order to control the disease.

Abstract
The increasing knowledge on immuno-inflammatory pathways allowed the development of new therapeutic options in the field of severe refractory asthma (SRA). It is therefore very important to accurately identify phenotypes and endotypes of patients potentially eligible for innovative treatments. The aim of this study was to describe a cohort of patients affected by SRA referring to the Pneumology Unit of Azienda USL di Reggio Emilia/IRCCS in Reggio Emilia, Italy. It is an observational cross-sectional study, investigating the proportion of subjects with eligibility criteria for biological treatments (omalizumab, mepolizumab, benralizumab) and non-pharmacological treatment (bronchial thermoplasty, BT). We enrolled 137 patients with SRA referring to the centre from June 1st, 2017 to June 30th, 2019. The results of this study showed that 125 (91%) of patients were eligible for at least one biologic and 94 (69%) were eligible for BT. Only 6 (4%) of patients had no criteria for any available SRA treatments. Among biologics, there were only 11 (8%) patients resulting in overlap between omalizumab, mepolizumab and benralizumab, and 22 (16%) overlap of patients when BT was included. Considering eligibility criteria for BT, only 6 (4%) patients had inclusion criteria for BT, instead in real life 28% of patients were treated with BT. The major comorbidities were: bronchiectasis, chronic rhinosinusitis with nasal polyps (CRSwNP), gastro-esophageal reflux disease (GERD), and eosinophilic granulomatosis with polyangiitis (EGPA). The prevalence of bronchiectasis was much higher in the mepolizumab (45%) and benralizumab (43%) groups than in omalizumab (1%) and BT (7%), p < 0,001; CRSwNP and GERD were equally present and EGPA was only present in the mepolizumab group. Overall, our population was eligible for biologicals in almost all cases, and a significant percentage of patients showed the presence of an overlap of allergic and eosinophilic endotypes. This implies the possibility of different therapeutic options and reiterates the need for a correct characterization of patients. This study confirmed how the identification of inflammatory endotypes and phenotypes represent a key role in the selection of the right therapy for the right patient.

Abstract
Severe asthma affects between 5 and 10% of patients with asthma worldwide and requires best standard therapies at maximal doses. A subgroup of patients remains refractory to all treatments. We describe two case reports with severe allergic asthma who progressively worsened over the years despite the best therapy. The patients were first treated with omalizumab, which was completely ineffective, and then with bronchial thermoplasty (BT), again without clinical benefit. Since our patients met the AIFA criteria for inclusion in mepolizumab treatment, a therapy with this anti-IL5 biological agent was initiated. In the first case (a 53-year-old female), after the second mepolizumab administration, symptoms improved progressively, with a reduction in the number and severity of exacerbations, so the patient could finally be discharged from hospital. At follow-up, it was possible to reduce oral corticosteroids and continuing with inhaled corticosteroids/long-acting beta-agonists and montelukast. The patient had only one exacerbation/year. Symptom control and quality of life improved significantly. In the second case report (a 55-year-old male), after the sixth mepolizumab administration, symptoms improved progressively, with a reduction in the number and severity of exacerbations. At follow-up, it was possible to reduce and stop oral corticosteroids, continuing with inhaled therapy and montelukast. Symptom control and quality of life improved significantly.These are the first cases of patients unresponsive to sequential omalizumab and BT but with good and prolonged clinical response to mepolizumab. Both cases suggest that also after the failure of two consecutive third-line treatments, a third treatment (mepolizumab) should be attempted.

Abstract
Background: Asthma is a highly prevalent chronic inflammatory airways disease, with a
considerable impact on quality of life (QoL). To express the effects of
asthma on patients’ subjective experience, patient-reported outcomes (PROs)
represent an important instrument. The asthma QoL questionnaire (AQLQ) is
one of the main PROs among these. Materials and methods: To identify long-term asthma-related QoL outcomes associated with omalizumab
therapy in patients with moderate-to-severe asthma, we developed a
systematic review according to the PRISMA guidelines. Published real-world
effectiveness studies of adults or adolescents (12 years or older) with
moderate-to-severe allergic asthma treated with omalizumab for at least 48
weeks were reviewed. Sources used were Medline
(PubMed), the Cochrane Library and
Google Scholar up to February 2018. In addition, a
cross-referencing search was conducted to complete the revision. Results: A total of 255 potential papers were identified in the first search through
the database. After full-text viewing, eight articles were finally included
in the review. We summarized the results according to the study design,
patient baseline characteristics and effectiveness outcomes assessed by AQLQ
score results: variation from baseline to the end of study. Results
confirmed the long-term benefits of omalizumab as an add-on therapy in
patients with uncontrolled moderate-to-severe allergic asthma. Since there
is a lot of evidence on omalizumab effectiveness, we aimed to focus on how a
therapy can change patient’s QoL in a long time period. Data showed
long-term effects of omalizumab treatment on subjective (PROs) and objective
(lung function, corticosteroid use, hospitalizations, asthma exacerbation)
effectiveness measures. Conclusion: Studies included in our review were observational trials that, due to their
design, present a potential risk of selection bias in the patients included.
Beyond this limit, the evaluation of QoL using the AQLQ showed a clear
increase over time, following both 48 weeks and 9 years of observation,
where QoL improvements still were significant over baseline values.

Abstract
Background: In this project the authors use a narrative medicine (NM) approach to assess the promotion of trust in the relationship between physicians and their asthma patients. Methods: Following a NM educational course for physicians, a research was carried out in which at least 5 written narratives (parallel charts) for each participating physician were collected and qualitatively analysed according to Bury’s classification and the Grounded Theory. Results: The results of this study were of speculative and clinical interest. In particular, 66 participants wrote 314 narratives (246 on adult and 68 on paediatric patients). As a result of applying the NM approach, when the relationships remained problematic, many physicians wrote with a moral style about their adult (67%), and paediatric patients (33%) - especially in cases of asthmatic children’s or adolescents’ overprotective or absent families (40%) -. On the contrary, physicians who were able to listen to their patients with empathy (35%) made more shared decisions with patients, even with those they initially had a bad relationship. The used words of welcome, interest and acceptance were promoting patients’ trust that lead to restoring their activities in 45% of cases, according to physicians self-reporting. Conclusions: These approaches of NM are useful in daily clinical practice, with the goal of improving the quality of life (QOL) of patients with severe asthma, even in cases in which the doctor-patient relationship isn’t initially good.

Abstract
BACKGROUND Severe asthma is a disease with a heavy socio-economic burden and a relevant impact on the life of patients. Mepolizumab (MEP) was recently introduced in practice. The previous data were favourable as efficacy and safety are concerned. Nowadays, we can report the clinical data after more than one year of use of MEP in the real-life setting. OBJECTIVE To evaluate the efficacy and safety of MEP in a real life framework, mainly concerning asthma exacerbations, steroid dependence, effects on respiratory function and adverse events. METHODS This retrospective analysis was performed on 138 patients, treated with MEP for at least 12 months, and referred to eleven severe asthma clinics in Italy. All patients met the criteria for severe uncontrolled asthma according to ATS/ERS guidelines and prescribing MEP conditions according to the Italian Drug Agency (AIFA). RESULTS We could observe 138 patients (78 female, age 58 ± 10 years). The average age of onset of asthma was 34 ± 16 years. The blood eosinophil count decreased from 822 ± 491/μL at baseline to 117 ± 96/μL (p < .0001) after 12 months of therapy. Exacerbations decreased from 3.8/year to 0.7/year (-81%; p < .0001). Steroid-dependent patients before MEP (80%) with a daily dose of 10.1 ± 9.4 mg prednisone decrease at 28% after 12 months with a mean of 2.0 ± 4.2 mg/day (p < .0001). The occurrence of adverse events was overall low. CONCLUSIONS & CLINICAL RELEVANCE In this real-life setting, MEP confirmed its efficacy and safety profile, already shown in clinical trials. This was apparent concerning exacerbation rate, systemic steroids intake and safety.

Abstract
BACKGROUND AND OBJECTIVE Enterobacteriaceae (EB) spp. family is known to include potentially multidrug-resistant (MDR) microorganisms, and remains as an important cause of community-acquired pneumonia (CAP) associated with high mortality. The aim of this study was to determine the prevalence and specific risk factors associated with EB and MDR-EB in a cohort of hospitalized adults with CAP. METHODS We performed a multinational, point-prevalence study of adult patients hospitalized with CAP. MDR-EB was defined when ≥3 antimicrobial classes were identified as non-susceptible. Risk factors assessment was also performed for patients with EB and MDR-EB infection. RESULTS Of the 3193 patients enrolled with CAP, 197 (6%) had a positive culture with EB. Fifty-one percent (n = 100) of EB were resistant to at least one antibiotic and 19% (n = 38) had MDR-EB. The most commonly EB identified were Klebsiella pneumoniae (n = 111, 56%) and Escherichia coli (n = 56, 28%). The risk factors that were independently associated with EB CAP were male gender, severe CAP, underweight (body mass index (BMI) < 18.5) and prior extended-spectrum beta-lactamase (ESBL) infection. Additionally, prior ESBL infection, being underweight, cardiovascular diseases and hospitalization in the last 12 months were independently associated with MDR-EB CAP. CONCLUSION This study of adults hospitalized with CAP found a prevalence of EB of 6% and MDR-EB of 1.2%, respectively. The presence of specific risk factors, such as prior ESBL infection and being underweight, should raise the clinical suspicion for EB and MDR-EB in patients hospitalized with CAP.

Abstract
Recent research in the field of bronchial asthma has mainly focused on eosinophilic disease phenotype. Several trials proved the efficacy and safety profile of eosinophils and interleukin (IL)-5 targeting molecules, currently approved for severe asthma and available on the market. They include mepolizumab and reslizumab, IL-5 blocking molecules, and benralizumab, targeting the IL-5 receptor and eliciting a NK cell-mediated antibody-dependent cellular cytotoxicity against eosinophils. Eosinophilic inflammation represents the common pathophysiological background of several conditions, providing the rationale for the use of the same biologics beyond asthma. Although with different evidence grade, from clinical trials to case reports, anti-IL-5 biologics have been investigated in eosinophilic granulomatosis with polyangitis, allergic bronchopulmonary aspergillosis, chronic eosinophilic pneumonia, nasal polyposis, hypereosinophilic syndrome, and eosinophilic esophagitis. However, non-negligible differences between asthma and other eosinophilic diseases, particularly in eosinophils homing (blood and/or tissues), target organs and thus clinical features, probably account for the different response to the same drug in different clinical conditions and highlights the need for tailoring the therapeutic approach by modulating the drug dose and/or by combination therapy with multiple drugs. The optimal safety and tolerability profile of anti-IL-5 drugs warrants further and larger experimental and real-life investigations, which are needed especially in the field of non-asthma eosinophilic diseases. This review aims at summarizing the rationale for the use of biologics in eosinophilic diseases and their mechanisms of action. The current efficacy and safety evidence about eosinophils and IL-5 targeting molecules in asthma and in eosinophilic conditions beyond bronchi is also discussed.

Abstract
The increasing knowledge on inflammatory pathways has driven the development of targeted biological therapies for severe refractory asthma. Among the recently developed biologics, the fully human monoclonal antibody dupilumab is an interesting therapeutic option, given its ability to inhibit the biological effects of both IL-4 and IL-13. We describe the case of a male, Caucasian, 56-year-old patient with allergic and eosinophilic severe asthma. Given the poor asthma control, he started treatment with add-on dupilumab, and after the tenth injection, he presented with a fever and bilateral pulmonary thickening. A significant increase in blood eosinophilia was also reported. The patient underwent a fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) and transbronchial lung biopsy (TBLB/TBB). BAL revealed eosinophils alveolitis (60%) while TBB showed findings compatible with chronic eosinophilic pneumonia (CEP). After prolonged treatment with oral corticosteroids, the clinical picture improved with resolution of CEP. Since the beginning of dupilumab treatment, simultaneously to a great improvement in asthma control, the patient showed a progressive increase in blood eosinophils count and subsequent onset of clinical-radiological pattern suggestive of CEP. Based on published data, dupilumab may have induced an alteration of the complex immunological pathway of our patient. This pathway is affected by both allergic and eosinophilic asthmatic endotypes, and consequently, the concomitant action of allergenic stimuli and eosinophils may have caused the appearance of eosinophilic pneumonia. To our knowledge, this is the first reported case of CEP as a possible severe side effect of dupilumab administration.

Abstract
Introduction: Subjects with severe Th2-high endotype usually respond to oral corticosteroids (OCS). However, they often require high dosages with incremental side effects and health-care costs. The advent of biological therapies provides an effective strategy to improve asthma control, as well as reduce OCS use. Various molecules have been developed, each targeting different pathways. We analyzed the two anti-IL-5 strategies, benralizumab and mepolizumab, based on pivotal trials (RCTs), mechanisms of action and their possible role on the steroid-sparing effect. Areas covered: This review analyzes the data from the benralizumab and mepolizumab RCTs, focusing on the advantages of each drug on clinical efficacy and the steroid-sparing effect. Expert opinion: Benralizumab may represent a promising therapeutic option in the treatment of eosinophilic asthma, due to its mechanism of action, which rapidly allows a reduction in the eosinophils' number, and a greater steroid-sparing effect.

Abstract
Severe refractory asthma is characterized by a higher risk of asthma-related symptoms, morbidities, and exacerbations. This disease also determines much greater healthcare costs and deterioration in health-related quality of life (HR-QoL). Another concern, which is currently much discussed, is the high percentage of patients needing regular use of oral corticosteroids (OCS), which can lead to several systemic side effects. Airway eosinophilia is present in the majority of asthmatic patients, and elevated levels of blood and sputum eosinophils are associated with worse control of asthma. Regarding severe refractory eosinophilic asthma, interleukin-5 (IL-5) plays a fundamental role in the inflammatory response, due to the profound effect on eosinophils biology. The advent of the biological therapies provided an effective strategy, even if the increased number of molecules with different targets raised the challenge of choosing the right therapy and avoid overlapping. When considering severe refractory eosinophilic asthma and anti-IL-5 treatments, it is not easy to define which drug to choose between mepolizumab, reslizumab, and benralizumab. In this article, we carried out an indirect comparison among literature data, especially between OCS reduction studies (ZONDA-SIRIUS) and pivotal studies (SIROCCO-MENSA), evaluating whether the clinical efficacy and the steroid-sparing effect of benralizumab may represent an advantage over other compounds. This data could help the clinician in the decision process of treatment choice, within the different available therapeutic options for eosinophilic refractory severe asthma.

Abstract
Mepolizumab (anti IL-5, monoclonal antibody) is commercially available in Italy since more than one year for the treatment of severe hypereosinophilic asthma. Its efficacy and safety were evaluated in several regulatory trials. The characteristics of this drug in real life began to be assessed only recently. We describe herein the drop-out rate observed with mepolizumab in real life, because this datum can indirectly reflect the safety and tolerability aspects. The demographic and clinical data of patients receiving mepolizumab for severe asthma were collected, and the number and reasons for discontinuation of the treatment were analyzed. The database involves 143 patients (67 male, age range 19-80 year) who received at least one dose of mepolizumab. The observed discontinuation rate was 6/143 (4.2%). Five out of 6 discontinuations were due to lack of response, and one was an adverse event (urticaria) probably related to the treatment. There was no clinical difference between the drop-out group and the patients still ongoing. As compared to the clinical trials published the discontinuation rate was lower in our population, especially for adverse events (7% vs 23.7%). Thus, the tolerability of mepolizumab, as derived from discontinuations, seems to be better in real-life than in clinical trials.

Abstract
We conducted a large global survey, Still Fighting for Breath, in patients with severe persistent asthma, 10 years after the Fighting for Breath survey to assess the impact of disease on patients' lives and to determine if control and management have changed in recent years. Data were collected from 1333 adults (aged >18 years) and caregivers of children (aged 6–17 years) with severe persistent asthma from nine countries through an online survey conducted in 2016 by GfK. A decade after the first survey, our results showed that the impact of severe asthma has not changed significantly and a high proportion of patients with severe asthma remain inadequately controlled. A large discrepancy was observed between the proportion of patients who perceived their asthma to be well controlled (42%) and the proportion of patients who reported to be well controlled as per the Global Initiative for Asthma (GINA) assessment (6%). Although most patients perceived their asthma to be controlled, many experienced frequent symptoms that affected their daily lives. Thus, there is a need for improved management (support and strategies) of patients with severe persistent asthma and improved coordination of efforts that would enable these patients to achieve better disease control.

Abstract
BACKGROUND Empirical antibiotic coverage for atypical pathogens in community-acquired pneumonia (CAP) has long been debated, mainly because of a lack of epidemiological data. We aimed to assess both testing for atypical pathogens and their prevalence in hospitalized patients with CAP worldwide, especially in relation with disease severity. METHODS A secondary analysis of the GLIMP database, an international, multicentre, point-prevalence study of adult patients admitted for CAP in 222 hospitals across 6 continents in 2015, was performed. The study evaluated frequency of testing for atypical pathogens, including L. pneumophila, M. pneumoniae, C. pneumoniae, and their prevalence. Risk factors for testing and prevalence for atypical pathogens were assessed through univariate analysis. RESULTS Among 3702 CAP patients 1250 (33.8%) underwent at least one test for atypical pathogens. Testing varies greatly among countries and its frequency was higher in Europe than elsewhere (46.0% vs. 12.7%, respectively, p < 0.0001). Detection of L. pneumophila urinary antigen was the most common test performed worldwide (32.0%). Patients with severe CAP were less likely to be tested for both atypical pathogens considered together (30.5% vs. 35.0%, p = 0.009) and specifically for legionellosis (28.3% vs. 33.5%, p = 0.003) than the rest of the population. Similarly, L. pneumophila testing was lower in ICU patients. At least one atypical pathogen was isolated in 62 patients (4.7%), including M. pneumoniae (26/251 patients, 10.3%), L. pneumophila (30/1186 patients, 2.5%), and C. pneumoniae (8/228 patients, 3.5%). Patients with CAP due to atypical pathogens were significantly younger, showed less cardiovascular, renal, and metabolic comorbidities in comparison to adult patients hospitalized due to non-atypical pathogen CAP. CONCLUSIONS Testing for atypical pathogens in patients admitted for CAP in poorly standardized in real life and does not mirror atypical prevalence in different settings. Further evidence on the impact of atypical pathogens, expecially in the low-income countries, is needed to guidelines implementation.

Abstract
Patients with severe asthma have a greater risk of asthma-related symptoms, morbidities, and exacerbations. Moreover, healthcare costs of patients with severe refractory asthma are at least 80% higher than those with stable asthma, mainly because of a higher use of healthcare resources and chronic side effects of oral corticosteroids (OCS). The advent of new promising biologicals provides a unique therapeutic option that could achieve asthma control without OCS. However, the increasing number of available molecules poses a new challenge: the identification and selection of the most appropriate treatment. Thanks to a better understanding of the basic mechanisms of the disease and the use of predictive biomarkers, especially regarding the Th2-high endotype, it is now easier than before to tailor therapy and guide clinicians toward the most suitable therapeutic choice, thus reducing the number of uncontrolled patients and therapeutic failures. In this review, we will discuss the different biological options available for the treatment of severe refractory asthma, their mechanism of action, and the overlapping aspects of their usage in clinical practice. The availability of new molecules, specific for different molecular targets, is a key topic, especially when considering that the same targets are sometimes part of the same phenotype. The aim of this review is to help clarify these doubts, which may facilitate the clinical decision-making process and the achievement of the best possible outcomes.

Abstract
BACKGROUND Severe Asthma Network in Italy (SANI) is a registry of patients recruited by accredited centers on severe asthma. OBJECTIVE To analyze epidemiological, clinical, inflammatory, functional, and treatment characteristics of severe asthmatics from the SANI registry. METHODS All consecutive patients with severe asthma were included into the registry, without exclusion criteria to have real-life data on demographics, asthma control, treatments (including biologics), inflammatory biomarkers, and comorbidities. RESULTS A total of 437 patients (mean age: 54.1 years, 57.2% females, 70.7% atopics, 94.5% in Global Initiative for Asthma severity step V) were enrolled into the study. The mean annual exacerbation rate was 3.75. The mean blood eosinophil level was 536.7 cells/mcL, and the average serum total IgE was 470.3 kU/L. Approximately 64% of patients were on regular oral corticosteroid treatment, 57% with omalizumab and 11.2% with mepolizumab. Most common comorbidities were rhinitis, nasal polyposis, and bronchiectasis. Patients with nasal polyposis had higher age of disease onset, higher blood eosinophil count, and lower frequency of atopy and atopic eczema. Bronchiectasis was associated with more frequent severe exacerbations, higher blood eosinophils, and total IgE. Stratifying patients, those with late-onset asthma were less frequently atopic (with less frequent allergic rhinitis and food allergy), and more frequently with nasal polyposis and higher serum total IgE levels. CONCLUSIONS This study revealed a high frequency of relevant comorbidities and that a substantial proportion of patients have late-onset asthma; all these features define specific different disease phenotypes. Severe asthma complexity and comorbidities require multidisciplinary approaches, led by specifically trained pulmonologists and allergists.

Abstract
Background: Acute respiratory failure can be triggered by several causes, either of pulmonary or extra-pulmonary origin. Pompe disease, or type II glycogen storage disease, is a serious and often fatal disorder, due to a pathological accumulation of glycogen caused by a defective activiy of acid α-glucosidase (acid maltase), a lysosomal enzyme involved in glycogen degradation. The prevalence of the disease is estimated between 1 in 40,000 to 1 in 300,000 subjects. Case presentation: This case report describes a difficult diagnosis of late-onset Pompe disease (LOPD) in a 52 year old Caucasian woman with acute respiratory failure requiring orotracheal intubation and subsequent tracheostomy for long-term mechanical ventilation 24 h/day. Despite a complex diagnostic process including several blood tests, bronchoscopy with BAL, chest CT, brain NMR, electromyographies, only a muscle biopsy allowed to reach the correct diagnosis. Discussion: The most frequent presentation of myopathies, including LOPD, is proximal limb muscle weakness. Respiratory related symptoms (dyspnea on effort, reduced physical capacity, recurrent infections, etc.) and respiratory failure are often evident in the later stages of the diseases, but they have been rarely described as the onset symptoms in LOPD. In our case, a third stage LOPD, the cooperation between pulmonologists and neurologists was crucial in reaching a correct diagnosis despite a very complex clinical scenario due to different confounding co-morbidities as potential causes of respiratory failure and an atypical presentation. In this patient, enzyme replacement therapy with infusion of alglucosidase alfa was associated with progressive reduction of ventilatory support to night hours, and recovery of autonomous walking.

Abstract
Background Bronchial thermoplasty (BT) is an endoscopic procedure for the treatment of severe refractory asthma, based on the local airways delivery of radio-frequency at 65 °C. Several controlled clinical studies demonstrated the effectiveness of BT on clinical outcomes, particularly the reduction of asthma exacerbations. During procedure or shortly after, significant but transient respiratory adverse events have been reported. Case report We describe the case of a male, caucasian, 56-year-old, non-smoker patient with non-allergic severe asthma. A few days after the second BT session performed in the left lower lobe, persistent haemoptysis appeared requiring patient hospitalization. A chest CT scan showed mild varicoid bronchiectasis and distal parenchymal infiltrate in the basal anterior segment of the left lower lobe. At fibreoptic bronchoscopy two small nodular neoformations were observed in sub-segmental areas of the same lobe. Histological examination showed mild non-specific inflammation of bronchial mucosa, and some large fragments of peribronchial pulmonary parenchyma with an area of haemorrhagic necrosis. The patient was treated empirically with co-amoxiclav, azithromycin and prednisone. A new chest CT showed a complete resolution of the parenchymal opacity. Finally, the patient underwent the third session of BT, without recurrence of haemoptysis or radiological changes. Discussion Bronchial thermoplasty is a generally safe procedure. To our knowledge this is the first report of necrosis of the treated bronchus and haemoptysis complicating BT after the second session. The pulmonary damage was most likely determined by a thermal shock induced by BT. One hypothesis could be a structural fragility of the treated bronchus, possibly related to bronchiectasis. A technical malfunction of the BT controller or the catheter, causing an excessive energy delivery could not be excluded. Adverse events following BT deserve particular attention but should not discourage clinicians from the application of this promising procedure.

Abstract
According to the current guidelines, severe asthma still represents a controversial topic in terms of definition and management. The introduction of novel biological therapies as a treatment option for severe asthmatic patients paved the way to a personalized approach, which aims at matching the appropriate therapy with the different asthma phenotypes. Traditional asthma phenotypes have been decomposing by an increasing number of asthma subclasses based on functional and physiopathological mechanisms. This is possible thanks to the development and application of different omics technologies. The new asthma classification patterns, particularly concerning severe asthma, include an increasing number of endotypes that have been identified using new omics technologies. The identification of endotypes provides new opportunities for the management of asthma symptoms, but this implies that biological therapies which target inflammatory mediators in the frame of specific patterns of inflammation should be developed. However, the pathway leading to a precision approach in asthma treatment is still at its beginning. The aim of this review is providing a synthetic overview of the current asthma management, with a particular focus on severe asthma, in the light of phenotype and endotype approach, and summarizing the current knowledge about "omics" science and their therapeutic relevance in the field of bronchial asthma.

Abstract
Asthma is a chronic obstructive respiratory disease characterised by bronchial inflammation. Its biological and clinical features have been widely explored and a number of pharmacological treatments are currently available. Currently several aspects of asthma pathophysiological background remain unclear, and this is represent a limitation for the traditional asthma phenotype approach. In this scenario, the identification of new molecular and clinical biomarkers may be helpful in order to better understand the disease, define specific diagnostic tools and highlight relevant novel targets for pharmacological treatments. Omics technologies offer innovative research tools for addressing the above mentioned goals. However, there is still a lot to do both in the fields of basic research and in the clinical application. Recently, genome-wide association studies, microRNAs and proteomics are contributing to enrich the available data for the identification of new asthma biomarkers. A precise approach to the patient with asthma, particularly with severe uncontrolled asthma, requires new and specific therapeutic targets, but also proper tools able to drive the clinician in tailoring the treatment. On the other hand, there is a need of predictors to treatment's response, particularly in the field of biological drugs, whose sustainability implies a correct and precise selection of the patients. Translating acquired omics knowledge in clinical practice may address the unmet needs described above, but large-scale studies are required in order to confirm their relevance and effectiveness in daily practice. Thus in our opinion the application of omics is still lagging in the real-life setting.

Abstract
BACKGROUND Bronchial thermoplasty (BT) is a non-pharmacological intervention for severe asthma whose mechanism of action is not completely explained by a reduction of airway smooth muscle (ASM). In this study we analyzed the effect of BT on nerve fibers and inflammatory components in the bronchial mucosa at 1 year. METHODS Endobronchial biopsies were obtained from 12 subjects (mean age 47 ± 11.3 years, 50% male) with severe asthma. Biopsies were performed at baseline (T0) and after 1 (T1), 2 (T2) and 12 (T12) months post-BT, and studied with immunocytochemistry and microscopy methods. Clinical data including Asthma Quality of Life Questionnaire (AQLQ) and Asthma Control Questionnaire (ACQ) scores, exacerbations, hospitalizations, oral corticosteroids use were also collected at the same time points. RESULTS A statistically significant reduction at T1, T2 and T12 of nerve fibers was observed in the submucosa and in ASM compared to T0. Among inflammatory cells, only CD68 showed significant changes at all time points. Improvement of all clinical outcomes was documented and persisted at the end of follow up. CONCLUSIONS A reduction of nerve fibers in epithelium and in ASM occurs earlier and persists at one year after BT. We propose that nerve ablation may contribute to mediate the beneficial effects of BT in severe asthma. TRIAL REGISTRATION Registered on April 2, 2013 at ClinicalTrials.gov Identifier: NCT01839591 .

Abstract
Severe asthma affects between 5% and 10% of patients with asthma worldwide and requires best standard therapies at maximal doses, but there is a subgroup of patients refractory to all treatments. We share a case report of a 53-year-old woman with a history of severe allergic asthma that progressively worsened over the years despite the best therapy. She had been hospitalized 35 times, including nine admissions to the respiratory intensive care unit due to severe exacerbations. To rule out other possible diagnoses, several investigations were performed, such as computed tomography scan of the chest and neck, fiberoptic laryngoscopy, antineutrophil cytoplasmic antibodies, and complete blood cell count. The patient was first treated with omalizumab, which was completely ineffective, and then with bronchial thermoplasty (BT), again without clinical benefit. The situation remained critical for about 3 months during the last hospitalization, but in February 2017, the Italian Medicines Agency approved the treatment of severe refractory eosinophilic asthma with mepolizumab (Nucala®). Given a blood eosinophil count of 300 cells/μL, our patient was started on 100 mg mepolizumab treatment. After the second administration, symptoms improved progressively, with a reduction in the number and severity of exacerbations, so the patient could finally be discharged from hospital. At follow-up, it was possible to reduce and then suspend oral corticosteroids by continuing only with inhaled corticosteroids/long-acting beta-agonists and montelukast. No further asthmatic exacerbations occurred; symptom control and quality of life improved significantly. To our knowledge, this is the first case of a patient unresponsive to omalizumab and BT but with excellent clinical response to mepolizumab. She is also the first patient to be treated with an anti-IL5 agent in Italy in a real-life clinical setting. The availability of new effective biological agents will allow many patients to resume as normal a life as possible, with a positive outcome also from a social and economic point of view.

Abstract
Asthma is characterized by inflammation of the airways that includes eosinophils, basal membrane thickening, epithelial sloughing, vascular changes, smooth muscle hypertrophy and hyperplasia, and mucous gland hyperplasia. Recently, there have been studies on the role of hypersensitivity and inflammation in asthma, but the role of bronchial smooth muscle remains unclear. Bronchial thermoplasty is an endoscopic procedure that is approved by the US Food and Drug Administration (FDA) for the treatment of severe refractory asthma, based on the local delivery of radio frequency at 65°C to the airways, with the aim of controlling bronchospasm through a reduction of airway smooth muscle (ASM). Several recent studies have shown significant improvement in clinical outcomes of bronchial thermoplasty for asthma, including symptom control, reduction in exacerbation and hospitalization rates, improved quality of life, and reduction in number of working days or school days lost due to asthma. Data from these recent studies have shown reduction in ASM following bronchial thermoplasty and changes in inflammation patterns. It has also been argued that bronchial thermoplasty may have modulating effects on neuroendocrine epithelial cells, bronchial nerve endings, TRPV1 nerve receptors, and type-C unmyelinated fibers in the bronchial mucosa. This may involve interrupting the central and local reflexes responsible for the activation of bronchospasm in the presence of bronchial hyperreactivity. Several questions remain regarding the use of bronchial thermoplasty, mechanism of action, selection of appropriate patients, and long-term effects. In this review, the role of ASM in the pathogenesis of asthma and the key aspects of bronchial thermoplasty are discussed, with a focus on the potential clinical effects of this promising procedure, beyond the reduction in ASM.

Abstract
The increasing understanding of the molecular biology and the etiopathogenetic mechanisms of asthma helps in identification of numerous phenotypes and endotypes, particularly for severe refractory asthma. For a decade, the only available biologic therapy that met the unmet needs of a specific group of patients with severe uncontrolled allergic asthma has been omalizumab. Recently, new biologic therapies with different mechanisms of action and targets have been approved for marketing, such as mepolizumab. Other promising drugs will be available in the coming years, such as reslizumab, benralizumab, dupilumab and lebrikizumab. Moreover, since 2010, bronchial thermoplasty has been successfully introduced for a limited number of patients. This is a nonpharmacologic endoscopic procedure which is considered a promising therapy, even though several aspects still need to be clarified. Despite the increasing availability of new therapies, one of the major problems of each treatment is still the identification of the most suitable patients. This sudden abundance of therapeutic options, sometimes partially overlapping with each other, increases the importance to identify new biomarkers useful to guide the clinician in selecting the most appropriate patients and treatments, without forgetting the drug-economic aspects seen in elevated direct cost of new therapies. The aim of this review is, therefore, to update the clinician on the state of the art of therapies available for refractory asthma and, above all, to give useful directions that will help understand the different choices that sometimes partially overlap and to dispel the possible doubts that still exist.

Abstract
Omalizumab is frequently used as add-on treatment to inhaled corticosteroids (ICS) and long-acting β2-agonists in patients with suboptimal control of severe asthma. Patients with severe asthma will typically require chronic treatment, although due to the limited amount of data available there are still some concerns about the safety and efficacy of long-term therapy with omalizumab. Herein, in an extension of a previous 4-year study, we report disease-related outcomes of 8 patients with severe persistent allergic asthma who have been followed for a total of 9 years in a real-life setting. Both quality of life (QoL) (evaluated using the Juniper Asthma-Related QoL Questionnaire [AQLQ]) and forced expiratory volume in 1 second (FEV1) showed sustained improvement at 9 years. The median values of AQLQ and FEV1 at 4 years were 5.5 and 82.0% compared to 5.9 and 85.5%, respectively, at 9 years, which were all significantly increased from baseline. After 9 years, the mean annual number of severe exacerbations was 0.63 compared to 5 at baseline. There also appeared to be a trend toward use of a lower dose of ICS at longer follow-up times. After 9 years, there were no safety concerns for continued use of omalizumab, and no asthma-related hospitalizations or emergency department visits were documented over the last 5 years. The present analysis is the longest reported clinical follow-up of omalizumab. Long-term maintenance treatment with omalizumab for up to 9 years is associated with continued benefits in reducing symptoms, exacerbations, and medication burden without any safety concerns.

Abstract
Despite several therapeutic choices, 10–20% of patients with severe uncontrolled
asthma do not respond to maximal best standard treatments, leading to a
healthcare expenditure of up to 80% of overall costs for asthma. Today, there
are new important therapeutic strategies, both pharmacological and
interventional, that can result in improvement of severe asthma management, such
as omalizumab, bronchial thermoplasty and other biological drugs, for example,
mepolizumab, reslizumab and benralizumab. The availability of these new
treatments and the increasing knowledge of the different asthmatic phenotypes
and endotypes makes correct patient selection increasingly complex and
important. In this article, we discuss the features of benralizumab compared
with other anti-interleukin-5 biologics and omalizumab, the identification of
appropriate patients, the safety profile and future developments.

Abstract
Severe asthma is characterized by major impairment of quality of life, poor symptom control and frequent exacerbations. Inflammatory, clinical and causative factors identify different phenotypes and endotypes of asthma. In the last few years, new treatment options have allowed for targeted treatments according to the different phenotypes of the disease. To accurately select a specific treatment for each asthmatic variant, the identification of appropriate biomarkers is required. Eosinophilic asthma is a distinct phenotype characterized by thickening of the basement membrane and corticosteroid responsiveness. This review reports the latest evidence on an anti-IL-5 monoclonal antibody, mepolizumab, a new and promising biological agent recently approved by the FDA specifically for the treatment of severe eosinophilic refractory asthma.

Abstract
Asthma is a chronic inflammatory disorder of the airways with variable clinical severity from very mild and occasional symptoms to recurrent critical exacerbations, at risk of fatal or near-fatal outcome, in a small percentage of patients. Within the different inflammatory cascades involved in asthma, eosinophils play a central role in the pathogenesis and largely influence disease severity. Interleukin-5 (IL-5) is the main cytokine controlling eosinophil activity and proliferation at the site of inflammation. Mepolizumab was the first biological humanized anti-IL-5 monoclonal antibody tested in randomized clinical trials on eosinophilic asthma and other eosinophilic diseases. On the basis of several positive clinical efficacy data, it has recently been approved by the US Food and Drug Administration for the treatment of severe eosinophilic asthma. Unfortunately, high costs are at present a critical issue. Future studies will probably help in the correct selection of a potential “responder phenotype”, allowing the prescription of this promising therapy to appropriate patients and best define cost-effectiveness issues.

Abstract
Asthma is a complex disorder frequently associated with a poor symptom control, concomitant morbidity, mortality, and significant health care costs due to lack of compliance or inadequate therapeutic options. Interleukin-5 (IL-5) plays a key role in the pathogenesis of eosinophilic disorders, and in the latest years has become a definite target for treatment. Besides asthma, other hypereosinophilic disorders include the hypereosinophilic syndrome, eosinophilic granulomatosis with polyangiitis, sinonasal polyposis, COPD with eosinophilic airway inflammation, allergic rhinitis, atopic dermatitis, eosinophilic esophagitis. The introduction of mepolizumab, a fully humanized monoclonal antibody that binds to IL-5, may represent a useful therapeutic option to control exacerbations and improve asthma-related quality of life in a subgroup of patients with persistent airway eosinophilia and moderate to severe asthma. Several studies carried out in recent years allow, at present, a careful patient selection for appropriate individualized treatment in severe asthma. Further research is anyway needed in order to better understand the pathogenetic mechanisms of asthma and to find new biomarkers. The high costs of biological agents as compared with standard drugs may be largely offset by increased clinical efficacy and good safety profile in selected patients.

Abstract
Background: Bronchial thermoplasty (BT) is a new therapeutic option for severe refractory asthma not controlled despite high dose inhaled corticosteroids plus long-acting bronchodilators and omalizumab in selected cases. Risk of pulmonary atelectasis after BT in severe asthma has been described in literature, but no details have been reported on the possible mechanisms of the complication.
Case presentation: A 49-year-old male with severe uncontrolled asthma was referred to BT. One hour after the first procedure, acute respiratory failure occurred with PaO2/FiO2 < 300. A CT scan showed atelectasis of the right lower and middle lobes. A new bronchoscopy was performed under non-invasive ventilation; the right lower and middle lobe bronchus were occluded by bronchus-shaped plugs, that were very difficult to remove despite repeated saline washings and fragmentation with forceps. The patient had a rapid resolution of respiratory failure. Four weeks later, 6 hours after the second session of BT, severe bronchospasm occurred with respiratory failure. Chest X-Ray showed atelectasis of the left lower lobe, prompting to perform a new flexible bronchoscopy on non-invasive ventilation. The exam showed again a plug occluding the left lower lobar bronchus, removed with forceps and washings. The histological analysis of the plugs demonstrated the massive presence of fibrin with mucus debris, rare Charcot-Leyden crystals, scattered macrophages, neutrophils, eosinophils and bronchial epithelial cells.
Conclusion: The originality of our case report is related to the recurrence of bronchial plugging with lobar atelectasis within one and five hours respectively, after two sequential BT procedures. At the histological evaluation the bronchial plugs appeared very different from the typical mucoid asthma plugs, being composed prevalently by fibrin. It can be hypothesized that intense thermal stimulation of the bronchial mucosa may represent a strong boost for inflammation in susceptible patients, with microvascular alteration induced directly by heat or through the release of mediators. Although in severe asthma a risk of atelectasis from the classical asthma mucoid plugs may be expected, the peculiarity of our case resides in the formation of fibrin plugs whose direct correlation with BT should be considered.

Abstract
Patients with severe asthma or COPD have often a suboptimal symptom control due to inadequate treatment. A better understanding of pathogenetic mechanisms, phenotypes, endotypes and the new technologies available in the fields of molecular biology and immunogenetics have made it possible to synthesize specific monoclonal antibodies virtually able to interact with any target antigen, or to open a way for new therapeutic target options. At the moment, the only biologic drug available in clinical practice is omalizumab. To overcome the limits of omalizumab, the research has focused on new monoclonal antibodies presenting higher avidity for IgE (e.g. ligelizumab and lumiximab) and ability to interact also with low affinity IgE receptor (FcεRII). At present, many new biological drugs with different mechanisms of action and targets are matter of research. It is very important to identify the asthmatic phenotype in order to select the most appropriate drug for the individual patient. The most promising agents are targeted against cytokines of Th2 pattern and related receptors, such as IL-2 (daclizumab) and IL-13 (lebrikizumab) or IL-5 in patients with hypereosinophilia (mepolizumab, reslizumab and benralizumab). Other interesting drugs have as a target TNF-α or its soluble receptor (infliximab, golimumab and etanercept) or IL-1 (canakinumab), a cytokine with an important systemic proinflammatory action. Finally, the discovery of increased levels of C5a in the airways of asthmatic patients has led to the synthesis of a specific monoclonal antibody (eculizumab). Further help should come from the identification of biomarkers that can guide in choosing the best treatment for the individual patient, such as IgE for omalizumab or periostin for lebrikizumab.

Abstract
BACKGROUND AND AIM Bronchoscopy is performed in a variety of different settings in Italy. The surveys conducted so far have highlighted the heterogeneity of the procedures and the frequent inability to adhere to the guidelines. The aim of this survey was to analyse procedures, training, and opinions of Italian respiratory physicians performing interventional bronchology in the clinical practice. METHODS The study was conducted retrospectively on 300 pulmonologists. From January to June 2008, these were invited to participate in an email survey to be sent out monthly to each participant for four consecutive months. RESULTS Two hundred and one respiratory physicians took part in the study, most of whom (83.5%) work in either Pulmonology or Interventional Pulmonology Units. The year before the survey, 21.2% of the participants had performed fewer than 100 examinations, 42.3% 100 to 300, and 36.6% more than 300 bronchoscopies; 53.9% were familiar with the international guidelines on the topic. Among the responders, 34.1% had received less than 6 months training, 55.3% considered further training in rigid bronchoscopy, laser procedures and thoracoscopy, invaluable for their professional activity. Adequate training for transbronchial needle aspirates, was reported by 49.6% of respondents. CONCLUSIONS Our data show that interventional bronchoscopy procedures are regularly performed according to current recommendations by over half of the Italian Pulmonologists participating in our survey. The need for more comprehensive basic education and training was put forward by the majority of physicians.

Abstract
Background Right-to-left shunt (RLS) may be the cause of marked hypoxemia, a respiratory insufficiency which is usually difficult to diagnose by respiratory physicians as it develops in the absence of an intrinsic lung disease. Case presentation We report a case of RLS in a patient with a hepatopulmonary syndrome caused by chronic autoimmune cholangitis. RLS was suspected clinically by physical examination and by standard CT imaging and MIP reconstruction of the pulmonary vascular bed. Repeated previous transthoracic echocardiography (TTE) studies did not reveal shunts or any cardiac defect. The final diagnosis was made by means of a minimally invasive transcranial Doppler examination with the use of saline agitated with 0.5 ml of patient’s blood as contrast solution. Conclusions Transcranial Colour-Coded Duplex Sonography (TCCS) with saline contrast medium injection is described to have a higher sensitivity than TTE and comparable to transesophageal echocardiography (TEE) in RLS diagnosis. The collaboration of neurologists in diagnosing respiratory insufficiency is very important as the examination is simple, well tolerated in comparison with the discomfort associated with transesophageal echocardiography, and minimally invasive in comparison with angiography, which is the last diagnostic procedure in this clinical scenario. In order to confirm RLS, TCCS with blood-saline contrast medium injection should be performed for the diagnosis of chronic hypoxemia for which causes are not detected with routine clinical examinations.

Abstract
Sarcoidosis is a multi-systemic inflammatory disease of unknown origin characterized by the presence of noncaseating epitheloid cell granulomas in multiple organs. Diagnosis is made on the basis of a compatible clinical-radiological scenario and the histological demonstration of the typical granulomas in the affected tissues. Interferons are immuno-modulators that have been used in a wide range of diseases, including hepatitis C virus infection, multiple sclerosis, and multiple myeloma and other types of tumours, including leukemia, lymphomas, Kaposi's sarcoma, and melanoma. Interferon-alpha-induced sarcoidosis has been reported repeatedly and there are two reports in the literature of cases of pulmonary sarcoidosis treated with interferon-1b therapy: one for advanced renal cell carcinoma and the other for multiple myeloma. A 35-year-old man on chronic immune-modulant Interferon-1b-based therapy for multiple sclerosis presented to the Neurology Unit with mild dyspnoea, dry cough, and transient pain to right upper abdomen. Lungs, spleen, liver, and almost all lymphnode stations of abdomen and mediastinum were clearly involved on ultrasound examination, chest X-ray, and computed tomography. A transbronchial biopsy showed non-caseating granuloma on histopathologic evaluation of the lungs. To the best of our knowledge, this is the first report of a chronic multisystemic sarcoidosis that was associated with interferon-beta treatment.

Abstract
OBJECTIVES The aim of this study was to assess the stability of the effectiveness of omalizumab as add-on treatment in 11 patients with severe persistent allergic asthma followed for 4 years. Secondary outcomes were safety and economic impact, in terms of use of healthcare resources. METHODS This retrospective study was designed to analyse a series of patients with severe allergic asthma treated with omalizumab. Patients were initially enrolled as part of the CIGE025A2425 international multicentre clinical trial. At the end (week 32), 11 responsive patients went on to complete the study and continued omalizumab treatment until June 2010. The monitoring visits coincided with the timescales planned for administering the drug and for the follow up. To estimate the economic impact, the PRE-POST treatment comparison was obtained by comparing the annual pretreatment costs with an annual average of the 4-year posttreatment period costs RESULTS After 4 years, 81.8% of patients showed a good/excellent Global Evaluation of Treatment Effectiveness scale score and 81.2% showed an excellent increase (>1.5) in the Asthma Quality of Life Questionnaire score. The average forced expiratory volume in one second (FEV(1)) at 4 years was 75.3% compared with the predicted normal value for each patient, with a net increase (p = 0.009) compared with baseline FEV(1) values (58.6%). The frequency of serious exacerbations dropped by 94.7% compared with the pretreatment period, while mild-moderate exacerbations fell by 41.8%. A reduction in costs was observed for hospital admissions (97.3%), visits to emergency department (ED) (97.5%) and mild-moderate exacerbations (84%). The average cost reduction of concomitant drugs remained at 36%. CONCLUSIONS This study confirms the effectiveness and reliability of omalizumab over the long term, while providing an excellent safety profile. The additional cost due the use of omalizumab was offset by the medium- and long-term savings associated with the reduction in hospital admissions and access to ED.

Abstract
INTRODUCTION Currently, omalizumab is indicated for the treatment of patients with severe allergic uncontrolled asthma despite optimal therapy. CASE PRESENTATION We studied a 52-year-old man who has been suffering from severe non allergic steroid-resistant asthma with increased levels of total IgE and a lot of comorbidity. After a 3 years long treatment with omalizumab, he presented a significant improvement in disease control in terms of hospitalizations, exacerbation, quality of life and lung function with good safety profile. CONCLUSION Our case shows, after a long follow-up, how omalizumab can be effective in a severe form of non-atopic asthma. It is therefore hoped that further studies can identify indicators that are able to give to clinicians information about patients who can be responsive to monoclonal anti-IgE antibody even if non allergic.

Abstract
Introduction Legionella pneumonia can appear with different levels of severity and it can often present with complications such as acute respiratory distress syndrome. Case presentation We report the case of a 44-year-old Caucasian man with Legionella pneumonia with successive development of severe acute respiratory distress syndrome. During his stay in intensive care the clinical and radiological situation of the previously observed acute respiratory distress syndrome unexpectedly worsened due to acute pulmonary eosinophilic infiltrate of iatrogenic origin. Conclusion Levofloxacin treatment caused the occurrence of acute eosinophilic infiltrate. Diagnosis was possible following bronchoscopic examination using bronchoaspirate and transbronchial biopsy.

Abstract
UNLABELLED Omalizumab is an anti-IgE monoclonal antibody available since 2006 for the treatment of GINA step 4 asthma. We studied a 41-year old male who has been suffering from severe steroid-resistant asthma with severe co-morbidity and treated with Omalizumab. He was found to be non-responder to the treatment until the 48th week, starting from which we began to see a distinct improvement in the symptoms and all the correlated parameters, in addition to remission of the co-existent allergy to milk. CONCLUSIONS we wish to point out the late response to Omalizumab, which occurred way beyond the times envisaged in literature. It seems possible that some patients are late responders to the drug.
