Background: Current availability of several biologic treatments for severe asthma makes it possible to choose the most appropriate for each patient. Sometimes a good percentage of patients with severe asthma may be eligible for biologics that target either the allergic phenotype or the eosinophilic one, but not all respond to that selected as first choice. The aim of our real-life study was to assess whether, for patients with severe eosinophilic allergic asthma, not previously controlled by the anti-IgE omalizumab, the shift to another biologic targeting interleukin-5, such as mepolizumab, may represent a good therapeutic choice. Methods: A total of 41 consecutive patients with severe, persistent allergic, eosinophilic asthma, uncontrolled despite treatment with omalizumab, were enrolled in seven certified Clinical Respiratory Units of Southern Italy (Catania, Catanzaro, Foggia, Bari, Palermo, and two University Respiratory Units of Naples) and shifted to mepolizumab without a wash-out period. Data at baseline, after at least 12 months of therapy with omalizumab, and after at least 12 months of treatment with mepolizumab were collected. Results: After at least 12 months of therapy with mepolizumab, patients experienced a significant decrease in the number of exacerbations/year (5.8 ± 1.8 versus 0.7 ± 0.9, p < 0.0001), an increment of asthma control test score (12 ± 2.7 versus 21.9 ± 2.7, p < 0.0001), an increase in pre-bronchodilator forced expiratory volume in 1 s (1.56 ± 0.45 l versus 1.86 ± 0.52 l, p < 0.0001), and a reduction of blood eosinophils (584 ± 196 cells/µl versus 82 ± 56 cells/µl, p < 0.0001). The percentage of patients who were dependent on corticosteroids significantly decreased from 46% at baseline to 5% during treatment with mepolizumab. Conclusion: Results of our real-life multicentric experience confirms that the shift to mepolizumab could be a good therapeutic strategy in severe eosinophilic allergic asthma not previously controlled by omalizumab.

Purpose Patients affected by COVID-19 are assumed to be at high risk of developing swallowing disorders. However, to our best knowledge, data on the characteristics and incidence of dysphagia associated with COVID-19 are lacking, especially in non-intubated patients. Therefore, we investigated the onset of swallowing disorders in patients with laboratory-confirmed COVID-19 infection who have not been treated with invasive ventilation, in order to evaluate how the virus affected swallowing function regardless of orotracheal intubation. Methods We evaluated 41 patients admitted to the COVID department of our Hospital when they had already passed the acute phase of the disease and were therefore asymptomatic but still positive for SARS-CoV-2 RNA by RT-PCR. We examined patients’ clinical history and performed the Volume-Viscosity Swallow Test (VVST). Each patient also answered the Swallowing Disturbance Questionnaire (SDQ). After 6 months, we performed a follow-up in patients with swallowing disorders. Results Eight of 41 patients (20%) presented with dysphagia symptoms during hospitalization and 2 of them (25%) still presented a SDQ high score and swallowing disorders with liquid consistency after 6 months. Conclusion Non-intubated patients can experience various grades of swallowing impairment that probably directly related to pulmonary respiratory function alterations and viral direct neuronal lesive activity. Although these symptoms show natural tendency to spontaneous resolution, their impact on a general physical impaired situation should not be underestimated, since it can adversely affect patients’ recovery from COVID-19 worsening health outcomes.
Background: Severe eosinophilic asthma decreases lung function and causes worsen symptoms, often forcing recurrent maintenance corticosteroid use. The aim of our real-life study was to evaluate the effectiveness of an add-on treatment with benralizumab in patients with severe eosinophilic asthma, paying particular attention to the impact on their quality of life (QoL).Materials and methods: In this prospective study, 10 outpatients with severe eosinophilic asthma were added-on with benralizumab and followed-up in our severe asthma clinic after 12 and 24 weeks. At each patient visit, pre-bronchodilator FEV1 and inflammatory markers were recorded. Variations in asthma symptoms control and QoL perception was assessed by validated questionnaires.Results: All the subjects experienced a marked reduction of nocturnal and diurnal symptoms over time and were able to stop using OCS, as documented by the improvement in Asthma control test (ACT) and Asthma Control Questionnaire score. Similarly, we recorded a statistically significant increase in patient’s QoL perception in EQ-VAS, EQ-5D-3L and Asthma Quality of Life Questionnaire (AQLQ) assessment (p < 0.05). Simultaneously we recorded a significant reduction in eosinophilic inflammation, an improvement in pre-bronchodilator FEV1. These results appear to be in line with those already obtained in the previous randomized controlled trials (RCTs).Conclusion: Our 24-weeks real life experience supports the effectiveness of an add-on treatment with benralizumab in reducing eosinophilic inflammation and OCS-use, increasing lung function and improving control of nocturnal and diurnal symptoms, as well as restoring severe asthma patients to a better QoL.
Background Idiopathic Pulmonary Fibrosis (IPF) is a degenerative interstitial lung disease with both a poor prognosis and quality of life once the diagnosis is made. In the last decade many features of the disease have been investigated to better understand the pathological steps that lead to the onset of the disease and, moreover, different types of biomarkers have been tested to find valid diagnostic, prognostic and therapy response predictive ones. In the complexity of IPF, microRNA (miRNAs) biomarker investigation seems to be promising. Methods We analysed the expression of five exosomal miRNAs supposed to have a role in the pathogenesis of the disease from serum of a group of IPF patients (n = 61) and we compared it with the expression of the same miRNAs in a group of healthy controls (n = 15). Results In the current study what emerged is let-7d down-regulation and, unexpectedly, miR-16 significant down-regulation. Moreover, through a cross-sectional analysis, a clustering of the expression of miR-16, miR-21 and miR-26a was found. Conclusions These findings could help the individuation of previously unknown key players in the pathophysiology of IPF and, most interestingly, more specific targets for the development of effective medications.
Transthoracic ultrasound (TUS) is a readily available imaging tool that can provide a quick real-time evaluation. The aim of this preliminary study was to establish a complementary role for this imaging method in the approach of interstitial lung diseases (ILDs). TUS examination was performed in 43 consecutive patients with pulmonary fibrosis and TUS findings were compared with the corresponding high-resolution computed tomography (HRCT) scans. All patients showed a thickened hyperechoic pleural line, despite no difference between dominant HRCT patterns (ground glass, honeycombing, mixed pattern) being recorded (p > 0.05). However, pleural lines’ thickening showed a significant difference between different HRCT degree of fibrosis (p < 0.001) and a negative correlation with functional parameters. The presence of >3 B-lines and subpleural nodules was also assessed in a large number of patients, although they did not demonstrate any particular association with a specific HRCT finding or fibrotic degree. Results allow us to suggest a complementary role for TUS in facilitating an early diagnosis of ILD or helping to detect a possible disease progression or eventual complications during routine clinical practice (with pleural line measurements and subpleural nodules), although HRCT remains the gold standard in the definition of ILD pattern, disease extent and follow-up.
