High dose rate endoluminal brachytherapy in the treatment of endobronchial lesions - experience of a single institution and literature review.

PURPOSE: To evaluate the efficacy and toxicity of Iridium-192 high-dose-rate endobronchial brachytherapy (HDR-EBT) for palliation of symptoms and for curative intent. MATERIAL AND METHODS: This is a retrospective study of a prospectively registered cohort of 31 patients with endobronchial lesions treated with HDR-EBT at our institution between 2008 and 2020. Eighteen patients were treated with palliative intent and 13 curative intent; 4 of them as a boost to external radiation therapy (XRT). The primary objectives of the study were to analyze the symptomatic relief, endoscopic response, and treatment-related toxicity. As a secondary endpoint, survival analyses were performed. RESULTS: In palliative setting, most of the symptomatic patients (80%) presented a significant clinical improvement and 75% presented endoscopic improvement of the lesions. In curative setting, all patients with visible lesions had endoscopic improvement and better survival than palliatively treated patients (median: 78 and 9 months, respectively; p = 0.002). There were no complications in 91.4% of the treatments: only one pneumonia, one pneumothorax and one bronchial stenosis occurred, all in palliative treatments. No fatal hemoptysis happened. Acute toxicity was mild (G ≤ 2) and transitory. DISCUSSION: HDR-EBT is an excellent, safe, and inexpensive palliative treatment of symptoms caused by endobronchial growth of tumors in the proximal airway, either as a single treatment or in combination with XRT. It can also be an alternative in the treatment of initial malignant tumors when surgery or XRT is not possible, and it may also play a role in treating non-malignant bronchial obstructions.

Economic Impact and Clinical Outcomes of Omalizumab Add-On Therapy for Patients with Severe Persistent Asthma: A Real-World Study.

BACKGROUND: Omalizumab is a fully humanized monoclonal antibody indicated as add-on therapy to improve asthma control in patients with severe persistent allergic asthma. AIMS: The aim of this study was to evaluate social, healthcare expenditure and clinical outcomes changes after incorporating omalizumab into standard treatment in the control of severe asthma. METHODS: In this multicentre retrospective study, a total of 220 patients were included from 15 respiratory medicine departments in the regions of Andalusia and Extremadura (Spain). Effectiveness was calculated as a 3-point increase in the Asthma Control Test (ACT) and a reduction in the annual number of exacerbations. The economic evaluation included both direct and indirect costs. Incremental cost-effectiveness ratio (ICER) was calculated. Results from the year before and the year after incorporation of omalizumab were compared. RESULTS: After adding omalizumab, improvement of lung function, asthma and rhinitis according to patient perception, as well as the number of exacerbations and asthma control measured by the ACT score were observed. Globally, both healthcare resources and pharmacological costs decreased after omalizumab treatment, excluding omalizumab cost. When only direct costs were considered, the ICER was €1712 (95% CI 1487-1995) per avoided exacerbation and €3859 (95% CI 3327-4418) for every 3-point increase in the ACT score. When both direct and indirect costs were considered, the ICER was €1607 (95% CI 1385-1885) for every avoided exacerbation and €3555 (95% CI 3012-4125) for every 3-point increase. CONCLUSIONS: Omalizumab was shown to be an effective add-on therapy for patients with persistent severe asthma and allowed reducing key drivers of asthma-related costs.

Factors Associated with Depression in COPD: A Multicenter Study.

INTRODUCTION: Depression is a prevalent comorbidity in COPD and has an impact on the prognosis of these patients, thereby making it important to study the factors associated with depression in patients with COPD. METHOD: A multicenter, observational and cross-sectional study was conducted to study the factors associated with depression in patients with COPD measured by the hospital anxiety and depression (HAD) questionnaire. We analyzed anthropometric variables and the number of exacerbations in the previous year and calculated the 6-min walking test and the body mass index, airflow obstruction, dyspnea, and exercise (BODE) index. All the patients completed the quality of life EQ-5D and the LCADL physical activity questionnaires. The relationship of these variables with depression was evaluated with two multiple logistic regression models. RESULTS: One hundred fifteen patients were evaluated (93 % male) with a mean age of 66.9 years (SD 8.8) and a mean FEV1 % of 44.4 % (SD 15.7 %). 24.3 % presented symptoms of depression (HAD-D > 8). These latter patients had worse lung function, greater dyspnea, reduced exercise capacity, a higher score in the BODE index, poorer quality of life, reduced physical activity, and more exacerbations. In the first logistic regression model, quality of life and the BODE index were associated with depression (AUC: 0.84; 0.74-0.94). In the second model including the variables in the BODE index, quality of life and dyspnea measured with the MRC scale (AUC: 0.87; 0.79-0.95) were associated with depression. CONCLUSIONS: Nearly one-quarter of the patients with COPD in this study presented clinically significant depression associated with worse quality of life, reduced exercise capacity, greater dyspnea, and a higher score in the BODE index.

Clinical outcomes and cost analysis of exacerbations in chronic obstructive pulmonary disease.

BACKGROUND: Exacerbations are a major cause of disability, hospital admissions, and increased healthcare costs in patients with chronic obstructive pulmonary disease (COPD). This study investigated the clinical outcomes of outpatients with moderate to severe exacerbated COPD and their related costs. METHODS: An observational study on the outcomes of ambulatory exacerbations of COPD was conducted. The course of the exacerbation was evaluated at a follow-up visit at 4 weeks. A cost analysis that encompassed the use of healthcare resources for treatment of the exacerbation was performed. RESULTS: A total of 260 patients were included, with a mean age of 68.3 years and a mean FEV1 (% predicted) of 58.9 %. Twenty-two percent of patients had significant cardiovascular comorbidity. The most frequently prescribed antibiotics were moxifloxacin in 137 cases and amoxicillin-clavulanate in 50 cases. The rate of failure at 4 weeks was 12.5 %, with no differences between the two most prescribed antibiotics; however, patients treated with moxifloxacin had symptoms for 1.9 fewer days (P = 0.01). The mean cost of the exacerbation was 344.96 (95 % CI: 48.55-641.78), with 9.6 % of the costs for drugs and 72.9 % for hospital care of patients for whom treatment had failed. CONCLUSIONS: Antibiotic treatment of our population was in compliance with local guidelines. The rate of failure observed in our study was lower than that reported in previous studies; however, the small percentage of patients that required hospital attention generated almost two-thirds of the total costs of the exacerbations.

Factors associated with high healthcare resource utilisation among COPD patients.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) places a huge economic burden on healthcare systems, especially patients with frequent exacerbations and co-morbidities. OBJECTIVES: To identify factors associated with high utilisation of healthcare resources in a population of patients with COPD. METHOD: We conducted an observational, cross-sectional, multicentre study with the aim of identifying the factors associated with high resource utilisation among patients with COPD. Sociodemographic and anthropometric characteristics of the study population, as well as data on health-related quality of life, respiratory symptoms, presence of anxiety and depression, physical activity and lung function were collected. We examined the relationship between these variables and high utilisation of healthcare resources, by performing a multivariate analysis based on a logistic regression model. RESULTS: 115 patients (64 were high users of healthcare resources, and 51 control patients) from 13 hospitals were selected. Patients presenting high resource utilisation had worse FEV1, worse basal SpO2, less distance walked in the 6-minute walk test, and increased dyspnoea. They also had a worse BODE index, worse scores in all dimensions of the EURO-QOL 5D and the LCADL scale, and displayed a higher prevalence of depression. Multivariate analysis yielded a statistically significant association between SpO2, LCADL scores, serum fibrinogen values and total leukocyte count, and high healthcare resource utilisation. CONCLUSIONS: COPD patients who incur higher healthcare resource utilisation show reduced physical activity, increased respiratory failure and increased systemic inflammation.

Factores asociados a la hospitalización por exacerbación de la enfermedad pulmonar obstructiva crónica / Factors associated with hospital admission for exacerbation of chronic obstructive pulmonary disease

Introducción: Las exacerbaciones de la enfermedad pulmonar obstructiva crónica (EPOC) que precisan ingreso hospitalario tienen un gran impacto en la progresión de la enfermedad y generan un alto gasto sanitario. Método: Se trata de un estudio observacional, multicéntrico y transversal, con el objetivo de identificar los factores asociados a las hospitalizaciones por exacerbaciones de la EPOC. Se obtuvieron variables sociodemográficas, antropométricas, de calidad de vida, síntomas respiratorios, presencia de ansiedad y depresión, actividad física y pruebas de función pulmonar. Se analizó su asociación con el ingreso hospitalario mediante análisis multivariante con un modelo de regresión logística. Resultados: Se analizaron 127 pacientes, 50 (39%) de los cuales habían sido hospitalizados. El 93,7% fueron hombres, con una edad media de 67 años (DE=9) y un FEV1 del 41,9% (DE=15,3). En el primer modelo obtenido, la SpO2 basal, el índice BODE y las visitas a urgencias se asociaron con el ingreso, y el área bajo la curva (ABC) ROC fue de 0,809. En un segundo modelo incluimos solo variables de fácil obtención (sin la prueba de la marcha), y solo la SpO2 y las visitas previas a urgencias fueron significativas, con un ABC ROC de 0,783. Conclusiones: El ingreso hospitalario por exacerbación de la EPOC se asocia a peor SpO2, mayor puntuación del índice BODE y un mayor número de visitas al servicio de urgencias. En caso de no disponer de la prueba de caminar 6min, las otras dos variables ofrecen una capacidad discriminativa similar(AU)

Introduction: Exacerbations of Chronic Obstructive Pulmonary Disease (COPD) that require hospital admission have a major impact on the progression of disease and generate high health costs. Method: A multi-center, cross-sectional, observational, study was conducted with the aim to identify factors associated with hospital admission in patients with COPD. We obtained data of socio-demographic and anthropometric characteristics, quality of life, respiratory symptoms, anxiety and depression, physical activity and pulmonary function tests. We analyzed their association with hospital admission with a multivariate analysis using a logistic regression model. Results: We analyzed 127 patients, 50 (39%) of whom had been hospitalized. 93.7% were men, mean age 67 years (SD=9) and a FEV1 of 41.9% (SD=15.3). In the first model obtained, the baseline SpO2, the BODE index and emergency room (ER) visits were associated with hospital admission and the area under the ROC curve (AUC) was 0.809. In a second model we included only variables readily available (without the 6 minutes walking test) and only the SpO2 and previous visits to the ER were significant with an AUC ROC 0.783. Conclusions: hospital admission for exacerbation of COPD is associated with poor SpO2, higher BODE index score and a greater number of visits to the ER. In case you do not have the 6 minutes walking test, the other two variables offer a similar discriminative ability(AU)

Endoscopic sealing of bronchopleural fistulas with submucosal injection of a tissue expander: a novel technique.

The occurrence of a bronchopleural fistula (BPF) continues to represent a challenging management problem, and is associated with high morbidity and mortality. A novel and successful technique that uses submucosal injection of a tissue expander for bronchoscopic occlusion of BPFs has been designed. This method may be used either alone or in combination with bronchoscopic instillation of n-butyl-cyanoacrylate glue. The occlusion technique is described, with a presentation of two patients who were successfully treated with this method. The submucosal injection of a tissue expander is an effective, economical and minimally invasive technique for managing BPFs.

CPAP titration: Different methods for similar clinical results.

BACKGROUND: Continuous positive airway pressure (CPAP) is the main treatment for obstructive sleep apnea-hypopnea syndrome (OSAHS). Polysomnography (PSG) is the gold standard for CPAP titration. However, alternative methods have been sought to titrate CPAP at less expense in terms of time and resources. The aim of this study was to analyze CPAP success in controlling OSAHS symptoms and adverse effects by two titration methods. METHODS: This was a retrospective, observational cohort study in which 200 CPAP-naive patients who had been referred to our sleep laboratory and diagnosed with OSAHS were evaluated on two consecutive visits. During the first visit, an initial CPAP pressure was established either by split-night PSG or by using a mathematical formula. On the second visit, 1 month later, symptom persistence and adverse effects of CPAP treatment were assessed. RESULTS: Patients included were 157 males (78.5%) and 43 females (21.5%) aged 56+/-10 years. 87 patients (43.5%) were titrated by PSG and 113 (56.5%) using the formula. At the second visit, symptoms had improved significantly for both groups with no significant differences in the presence of adverse effects. The initial pressure had to be readjusted in five patients. CONCLUSIONS: This study suggests that formula titration can control symptoms as effectively as split-night titration. A prompt evaluation of the patient is advisable in order to ensure compliance with treatment and to correct possible adverse effects.
