Hemoptysis due to a large endobronchial mass successful regression after the use of high flow nasal cannula

In recent years, high flow nasal cannula is being increasingly used. Most studies showed positive results when used in hypoxaemic respiratory failure. Its use in a patient with a large endobronchial mass has not yet being described. We report a patient who presented with hemoptysis and hypoxaemic respiratory failure second to a large mass obstructing the right main bronchus. High flow oxygen via nasal cannula was initiated with a quick improvement of the hemoptysis and the oxygen saturation. Thus, allowing the patient to be rapidly stabilized

Expression profiling of miRNA-145 and miRNA-338 in serum and sputum of patients with COPD, asthma, and asthmaâCOPD overlap syndrome phenotype

Background and objectives: A new phenotype with overlapping characteristics between asthma and chronic obstructive pulmonary disease (COPD) called asthmaâCOPD overlap syndrome (ACOS) is emerging among inflammation diseases. To date, there is no agreement on specific criteria to define this syndrome, and the current guidelines are insufficient to classify the analogy and differences between overlap and COPD or asthma phenotypes. It would be necessary to identify new biomarkers able to identify these diseases clearly. Thus, the aim of this study was to identify a serum and supernatant of sputum microRNA (miRNA) expression profile of miRNA-145 and miRNA-338 in patients with asthma (n=13), COPD (n=31), and ACOS (n=8) and controls (n=7). Methods: The expression was evaluated using quantitative real-time polymerase chain reaction (qRT-PCR). For statistical analysis, the ANOVA test, KruskalâWallis test, MannâWhitney U-test, and Spearmanâs rank correlation were used. Results: The main finding of this work is that the expression of miRNA-338 is higher in the supernatant of different obstructive diseases than in peripheral blood, while miRNA-145 is higher only in the supernatant of asthma patients. The expression of both selected miRNAs is higher in the supernatant of asthma and COPD patients than in controls. Conclusion: Differences in sputum miRNA expression profile were observed between patients with ACOS and asthma or COPD, which underline the potential role of miRNA as a biomarker that is able to discriminate patients with ACOS, asthma, and COPD

Exhaled Breath Condensate (EBC) for SARS-CoV-2 diagnosis still an open debate

: The real-time PCR (RT-PCR) on nasopharyngeal swabs (NPS) is the gold standard for the diagnosis of SARS-CoV-2. The exhaled breath condensate (EBC) is used to perform collection of biological fluid condensed in a refrigerated device from deep airways' exhaled air. We aimed to verify the presence of SARS-CoV-2 virus in the EBC from patients with confirmed SARS-CoV-2 infection by RT-PCR, and to determine if the EBC may represent a valid alternative to the NPS. Methods: Seventeen consecutive patients admitted to the Emergency Department of the Policlinico were enrolled in the present study with RT-PCR, clinical and radiological evidence of SARS-CoV-2. Within 24 hours from the NPS collection the EBC collection was performed on SARS-CoV-2 positive patients. Informed written consent was gathered and the Ethic Committee approved the study. Results: The mean age of patients was 60 years (24-92) and 64.7% (11/17) were male. Patient n. 9 and n.17 died. All NPS resulted positive for SARS-CoV-2 at RT-PCR. RT-PCR on EBC resulted negative for all but one patients (patient n.12). Conclusion: In this study we did not find any correlation between positive NPS and the EBC in all but one patients enrolled. Based on these data which greatly differ from previous reports on the topic, this study opens several questions related to small differences in the complex process of EBC collection and how EBC could be really standardized for the diagnosis of SARS-CoV-2 infection. Further studies will be warranted to deepen this topic

Long-term home noninvasive ventilation (LTHNIV) in restrictive thoracic diseases: The Italian snapshot

Long-term home noninvasive ventilation (LTHNIV) in restrictive thoracic diseases was explored via the recently published international REINVENT ERS survey. The Italian subset of respondents (ITA-r), the highest above all participating nations, was analyzed and compared to non-Italian respondents (NO-ITA-r). The ITA-r represented 20% of the total answers examined. Ninety-four percent were physicians, whose half worked in a respiratory ICU (RICU). ITA-r mainly worked in community hospitals vs NO-ITA-r who are largely affiliated with university hospitals (p<0.0001). Amyotrophic lateral sclerosis (ALS) was considered the most common medical condition leading to NIV indication by both ITA-r and NO-ITA-r (93% vs 78%, p>0.5). A greater proportion of ITA-r considered MIP/MEP the most important test for NIV initiation as compared to NO-IRA-r (p<0.05). There was no significant difference for both ITA-r and NO-ITA-r as regards the other questions. This study illustrates Italian LTHNIV practices in patients with NMD and it shows some important differences with the other countries' practices but agreement in terms of goals to achieve, reasons to initiate NIV, and practices among the two communities

Real-Life effects of benralizumab on exacerbation number and lung hyperinflation in atopic patients with severe eosinophilic asthma.

Background: The humanized monoclonal antibody benralizumab targets the α subunit of the interleukin-5 (IL-5) receptor and the FcγRIIIa receptor expressed by natural killer cells. Through this dual mechanism of action, benralizumab neutralizes the pro-eosinophil functions of IL-5 and promotes eosinophil apoptosis. Objectives and methods: The present real-life study aimed to evaluate, in 22 allergic patients with severe eosinophilic asthma, the effects of benralizumab on asthma exacerbations and lung hyperinflation. Results: In this regard here we show that, after 24 weeks of add-on treatment, benralizumab completely depleted peripheral blood eosinophils (from 810 to 0 cells/μL; p < 0.0001), and significantly decreased both asthma exacerbation number (from 4 to 0; p < 0.0001) and residual volume (from 2720 to 2300 mL; p < 0.01). Moreover, at the same time point (24 weeks) benralizumab also increased pre-bronchodilator FEV1 (from 1295 to 1985 mL; p < 0.0001), FVC (from 2390 to 2974 mL; p < 0.0001), FEF25−75 (from 0.6 to 1.42 L/sec; p < 0.0001), IC (from 1940 to 2460 mL; not significant), and ACT score (from 14.73 to 22.95; p < 0.0001), as well as reduced prednisone intake (from 25 to 0 mg; p < 0.0001). Conclusion: In conclusion, our results suggest that via its anti-eosinophil actions benralizumab improved airflow limitation, lung hyperinflation, and respiratory symptoms, as well as lowered asthma exacerbation rate and abrogated OCS consumption in most patients

SARS-CoV-2 pneumonia and Eisenmenger’s Syndrome: doubling the challenge

Eisenmenger’s syndrome (ES) is the most severe phenotype of pulmonary arterial hypertension (PAH) secondary to congenital heart disease. In these cases, a significant systemic-to-pulmonary (left-to-right) shunting triggers the development of pulmonary vascular disease (PVD) and pulmonary hypertension. In cases of acute hypoxemic respiratory failure in patients with ES, high flow nasal cannula (HFNC) oxygen therapy should be considered as a first-line approach in order to avoid pulmonary complications and right ventricular overload related to positive pressure ventilation. Here, we report a case of HFNC use in a patient with COVID-19 infection and ES

Prevalence of comorbidities in patients with obstructive sleep apnea syndrome, overlap syndrome and obesity hypoventilation syndrome

Sleep-disordered breathing causes a burden to the sufferer, the health care system and the society. Most studies have focused on obstructive sleep apnea (OSA); however, the prevalence of comorbidities in patients affected by overlap syndrome (OS) and obesity hypoventilation syndrome (OHS) has not been carefully evaluated

Female gender and psychological profile of outpatients attending Post-COVID-19 follow-up: some preliminary results

Background: The Post-COVID syndrome, characterized by persistence of psychological, neurologic, and physical symptoms, affects a large proportion of COVID-19 survivors. Specifically, females seem at increased risk of experiencing more psychological manifestations of Post-COVID Syndrome. Methods: A sample of 60 PCR (Polymerase Chain Reaction) confirmed COVID-19 outpatients (48.3% female; age mean= 56.1; SD= 10.8) attending an outpatient clinic dedicated to Post-COVID-19 follow-up was enrolled for this study. Each participant completed the Psychosocial Index to assess stress, well-being, psychological distress, and illness behavior, the Impact of Event Scale – Revised to evaluate post-traumatic stress symptoms and, the Hospital Anxiety and Depression Scale to assess anxiety and depression; the Connor-Davidson Resilience Scale to assess resilience; and N scale of NEO Five Factor to assess “Neuroticism”. Results: More than half of patients showed clinical or subclinical anxiety and depressive symptoms. Post-traumatic stress symptoms were found in 58.3% of sample. Resilience levels were in a medium range (71.0 ± 15.2). Statistical analysis found a predominance of depressive symptomatology (p = 0.0453), hyperarousal manifestations (p = 0.0049), perception of stress (p = 0.0001) and trait of neuroticism in women (p 0.0001). Our results show psychological distress, post-traumatic symptoms, poor psychological well-being, depression and anxiety symptoms for several weeks after infection in patients who had COVID-19. Moreover, female outpatients had a higher perception of distress, hyperarousal manifestations and depressive symptomatology than the male counterpart.                    Conclusions: As a novelty, this study gives us a deeper understanding of the psychological Post-COVID-19 profile in a clinical sample of pneumological outpatients. Moreover, it focused on gender differences identifying the female gender as a risk factor with respect to psychological illness. Our findings suggest the relevance of planning personalized interventions and assessment aimed at higher psychopathological risk groups, such as females

Real-life effects of dupilumab in patients with severe type 2 asthma, according to atopic trait and presence of chronic rhinosinusitis with nasal polyps

BackgroundThe efficacy of dupilumab as biological treatment of severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) depends on its ability to inhibit the pathophysiologic mechanisms involved in type 2 inflammation.ObjectiveTo assess in a large sample of subjects with severe asthma, the therapeutic impact of dupilumab in real-life, with regard to positive or negative skin prick test (SPT) and CRSwNP presence or absence.MethodsClinical, functional, and laboratory parameters were measured at baseline and 24 weeks after the first dupilumab administration. Moreover, a comparative evaluation was carried out in relation to the presence or absence of SPT positivity and CRSwNP.ResultsAmong the 127 recruited patients with severe asthma, 90 had positive SPT, while 78 reported CRSwNP. Compared with the 6 months preceding the first dupilumab injection, asthma exacerbations decreased from 4.0 (2.0-5.0) to 0.0 (0.0-0.0) (p &lt; 0.0001), as well as the daily prednisone intake fell from 12.50 mg (0.00-25.00) to 0.00 mg (0.00-0.00) (p &lt; 0.0001). In the same period, asthma control test (ACT) score increased from 14 (10-18) to 22 (20-24) (p &lt; 0.0001), and sino-nasal outcome test (SNOT-22) score dropped from 55.84 ± 20.32 to 19.76 ± 12.76 (p &lt; 0.0001). Moreover, we observed relevant increases in forced expiratory volume in one second (FEV1) from the baseline value of 2.13 L (1.62-2.81) to 2.39 L (1.89-3.06) (p &lt; 0.0001). Fractional exhaled nitric oxide (FeNO) values decreased from 27.0 ppb (18.0-37.5) to 13.0 ppb (5.0-20.0) (p &lt; 0.0001). These improvements were quite similar in subgroups of patients characterized by SPT negativity or positivity, and CRSwNP absence or presence. No statistically significant correlations were detected between serum IgE levels, baseline blood eosinophils or FeNO levels and dupilumab-induced changes, with the exception of FEV1 increase, which was shown to be positively correlated with FeNO values (r = 0.3147; p &lt; 0.01).ConclusionOur results consolidate the strategic position of dupilumab in its role as an excellent therapeutic option currently available within the context of modern biological treatments of severe asthma and CRSwNP, frequently driven by type 2 airway inflammation
