Background: Exacerbations of COPD (ECOPD) have a major impact on patients and healthcare systems across the world. Precise estimates of the global burden of ECOPD on mortality and hospital readmission are needed to inform policy makers and aid preventive strategies to mitigate this burden. The aims of the present study were to explore global in-hospital mortality, post-discharge mortality and hospital readmission rates after ECOPD-related hospitalisation using an individual patient data meta-analysis (IPDMA) design.Methods: A systematic review was performed identifying studies that reported in-hospital mortality, post-discharge mortality and hospital readmission rates following ECOPD-related hospitalisation. Data analyses were conducted using a one-stage random-effects meta-analysis model. This study was conducted and reported in accordance with the PRISMA-IPD statement.Results: Data of 65 945 individual patients with COPD were analysed. The pooled in-hospital mortality rate was 6.2%, pooled 30-, 90- and 365-day post-discharge mortality rates were 2.0%, 6.4% and 12.2%, respectively, and pooled 30-, 90- and 365-day hospital readmission rates were 11.8%, 26.5% and 38.2%, respectively, with noticeable variability between studies and countries. Strongest predictors of mortality and hospital readmission included noninvasive mechanical ventilation and a history of two or more ECOPD-related hospitalisations <12 months prior to the index event.Conclusions: This IPDMA stresses the poor outcomes and high heterogeneity of ECOPD-related hospitalisation across the world. Whilst global standardisation of the management and follow-up of ECOPD-related hospitalisation should be at the heart of future implementation research, policy makers should focus on reimbursing evidence-based therapies that decrease (recurrent) ECOPD.

Noninvasive ventilation (NIV) reduces the rate of endotracheal intubation (ETI) and overall mortality in severe acute exacerbation of COPD (AECOPD) with acute respiratory failure and is increasingly applied in respiratory intermediate care units. However, inadequate patient selection and incorrect management of NIV increase mortality. We aimed to identify factors that predict the outcome of NIV in AECOPD. Also, we looked for factors that influence ventilator settings and duration. A prospective cohort study was undertaken in a respiratory intermediate care unit in an academic medical center between 2016 and 2017. Age, BMI, lung function, arterial pH and pCO2 at admission (t0), at 1–2 h (t1) and 4–6 h (t2) after admission, creatinine clearance, echocardiographic data (that defined left heart dysfunction), mean inspiratory pressure during the first 72 h (mIPAP-72 h) and hours of NIV during the first 72 h (dNIV-72 h) were recorded. Main outcome was NIV failure (i.e., ETI or in-hospital death). Secondary outcomes were in-hospital mortality, length of stay (LOS), duration of NIV (days), mIPAP-72 h, and dNIV-72 h. We included 89 patients (45 male, mean age 67.6 years) with AECOPD that required NIV. NIV failure was 12.4%, and in-hospital mortality was 11.2%. NIV failure was correlated with days of NIV, LOS, in-hospital mortality (p < 0.01), and kidney dysfunction (p < 0.05). In-hospital mortality was strongly associated with days of NIV (OR 1.27, 95%CI: 1.07–1.5, p < 0.01) and with FEV1 (p < 0.05). All other investigated parameters (including left heart dysfunction, dNIV-72 h, mIPAP-72 h, pH, etc.) did not influence NIV failure or mortality. dNIV-72 h and days of NIV were independent predictors of LOS (p < 0.01). Regarding the secondary outcomes, left heart dysfunction and pH at 1-2 h independently predicted NIV duration (dNIV-72 h, p < 0.01), while BMI and baseline pCO2 predicted NIV settings (mIPAP-72 h, p < 0.01). In-hospital mortality and NIV failure were not influenced by BMI, left heart dysfunction, age, nor by arterial blood gas values in the first 6 h of NIV. Patients with severe acidosis and left heart dysfunction required prolonged use of NIV. BMI and pCO2 levels influence the NIV settings in AECOPD regardless of lung function.

Allergen immunotherapy (AIT) is considered the only disease-modifying treatment available at present for allergic disorders. Its main benefits include improvement of symptoms, decreased need for ph... Plain language summary In the last decades, allergic diseases have become a public health concern worldwide. Currently, their treatment is mainly based on medications that control the symptoms or d...

Background: Hypersensitivity reactions induced by chemotherapeutic drugs may influence the course of the oncologic disease by preventing doctors from prescribing first‐line therapy. In order to prevent another hypersensitivity reaction to the culprit chemotherapeutic agent, the physician can decide between two possibilities: premedication or desensitisation protocols. Rapid drug desensitisation showed successful results for most patients, but some of them may develop symptoms. Although omalizumab is not licensed as premedication or adjuvant therapy in chemotherapy desensitisation protocols, there have been published some case reports and small sample size studies that indicated promising results.Methods: We reviewed all the published literature regarding the use of omalizumab during chemotherapy desensitisation protocols.Results and conclusions: We found a great heterogeneity between the doses and the interval between omalizumab injections and chemotherapy ‐ rapid drug desensitisation, but most of the studies showed promising results. As a corollary, we propose a dose regimen of omalizumab administered before the first desensitisation protocol. Then, omalizumab should be administered one day before every chemotherapy regimen. Omalizumab might be used as an adjuvant therapy and might be a solution for a hopeless situation.

Childhood interstitial lung disease (chILD) includes a heterogeneous spectrum of rare respiratory disorders in children associated with substantial morbi-mortality. Interstitial tissue, and other pulmonary structures, epithelium, blood vessels, or pleura are involved, resulting in a restrictive lung disfunction. Respiratory symptoms set in progressively and are often subtle, making thorough clinical history and physical examination fundamental. The etiology often is obscure. The clinical presentation mimics pneumonia or asthma, leading to a diagnostic delay. Challenging diagnosis may require genetic tests, bronchoalveolar lavage, or lung biopsy. Alongside general supportive therapeutic measures, anti-inflammatory, immunosuppressive or antifibrotic agents may be used, based on data derived from adult studies. However, if accurate diagnosis and treatment are delayed, irreversible chronic respiratory failure may ensue, impacting prognosis. The most frequent chILD is hypersensitivity pneumonitis (HP), although it is rare in children. HP is associated with exposure to an environmental antigen, resulting in inflammation of the airways. Detailed antigen exposure history and identification of the inciting trigger are the cornerstones of diagnostic. This article provides the current state of chILD, revealing specific features of HP, based on a clinical case report of a patient admitted in our clinic, requiring extensive investigations for diagnosis, with a favorable long-term outcome.

Background and Objectives: Patient’s behaviours, attitudes and beliefs related to asthma and its treatment were shown to influence the adherence to therapy and the level of asthma control. This survey aimed to assess the level of asthma control and patient-reported behaviours, attitudes and expectations related to their disease in Romanian patients. Materials and Methods: This cross-sectional quantitative survey was performed in February-March 2019 and enrolled 70 specialist physicians experienced in asthma management and 433 asthma patients under their care. Results: Of the 433 patients enrolled, 19.4% had mild asthma, 60.5% moderate asthma and 20.1% severe asthma. For the previous 12 months, asthma symptoms, exacerbations and emergency room visits were common in the sample analysed, with significantly higher figures in severe asthma patients (p < 0.001). The most important treatment goal for asthma patients was participation in all activities of daily living, while for physicians this was preventing asthma exacerbations. The valuation of the treatment goals was different between patients with severe asthma and those with mild and moderate forms. Based on the patients’ responses, 3 attitude clusters were identified: empowered savvy (36.5% of the patients), pessimistic non-compliers (43.2%), and anxious strugglers (20.3%). “Empowered savvy” had the lowest frequency of severe asthma, the highest adherence to maintenance therapy and the highest level of confidence in the effectiveness of asthma medication. The opposite of this attitude cluster is the “anxious strugglers”, containing more patients with severe asthma, a higher score for worries about asthma therapy and better self-reported knowledge of their treatment, contrasting with a proportion of 25% taking maintenance therapy only when having breathing difficulties. Conclusion: Asthma control in Romania remains poor, with frequent exacerbations and hospitalizations. The differences in treatment goals found between patients and physicians and between different asthma severity groups suggest the need for more patient-centred approaches.
