Inercia clínica o terapéutica en neumología: una reflexión sobre su definición y actores principales / Clinical or therapeutic inertia in pneumology: critical reflection on its definition and main actors

La inercia clínica se define como los fallos del médico en el inicio o la intensificación del tratamiento cuando están indicados. Nuestro objetivo es reflexionar sobre este concepto aplicado en enfermedad pulmonar obstructiva crónica y asma, y el papel del profesional sanitario y del sistema de salud como actores implicados. Dejamos aparte la inercia del paciente para otro ámbito de estudio e intervención. Proponemos definir la inercia clínica para procesos durante el diagnóstico y el tratamiento cuando no se inicia o modifica (intensifica o disminuye) una terapia. También se identifican los factores que contribuyen a la inercia clínica o terapéutica y se plantean estrategias de mejora. (AU)

Clinical inertia is defined as the physician’s failure to initiate or intensify treatment when it is indicated. Our objective is to reflect on this concept applied to chronic obstructive pulmonary disease and asthma, and the role of health professional and health system as stakeholders. We leave patient inertia aside for another area of study and intervention. We propose to define clinical inertia for diagnosis and therapeutic processes when a treatment is not started or modified (intensifies or decreases). Factors that contribute to clinical and/or therapeutic inertia are also identified and improvement strategies are proposed. (AU)

Predictors of success/failure in the control of asthmatic smoking patients under conditions of clinical practice.

BACKGROUND: Tobacco smoking directly affects the airway, where it triggers a very strong local inflammatory response. OBJECTIVE: To determine the predictors of improvement or worsening of asthma control in asthmatic smokers. METHODS: Observational, prospective, multicenter, single cohort study, carried out in the outpatient pulmonology departments with a follow-up period of 6 months. The treatment was adjusted according to the indications of standard clinical practice. RESULTS: 196 patients were included, with a mean age of 54.64 years.39% of the patients were active smokers. Interpreting an Asthma Control Questionnaire (ACQ) score of ≤ 0.75 as asthma control, this was achieved in 30.2% of the cases. Patients with greater adherence were more likely to improve their asthma symptoms (p < 0.05), defined as a decrease in ACQ of 0.5 points or more at the final visit, while taking concomitant medication was a negative risk factor for improvement (p < 0.001). An eosinophil value >300 was a predictor for achieving control (p < 0.01). Patients treated with fluticasone propionate/formoterol versus those receiving budesonide/formoterol or beclomethasone/formoterol had a lower ACQ score (p < 0.01 and p < 0.01, respectively). CONCLUSION: Asthmatic patients with active tobacco exposure and a higher number of anti-asthma medications are more likely to have poorer control. Correct adherence to treatment is the main intervention to be performed to achieve the control. An eosinophil count greater than 300 was the main predictor for achieving control. Fluticasone propionate/formoterol FP/FORM was associated with a greater likelihood of improving ACQ score.

Switching to the Dry-Powder Inhaler Easyhaler®: A Narrative Review of the Evidence.

Asthma and chronic obstructive pulmonary disease (COPD) are major causes of morbidity and mortality worldwide. Optimal control of these conditions is a constant challenge for both physicians and patients. Poor inhaler practice is widespread and is a substantial contributing factor to the suboptimal clinical control of both conditions. The practicality, dependability, and acceptability of different inhalers influence the overall effectiveness and success of inhalation therapy. In this paper, experts from various European countries (Finland, Germany, Hungary, Italy, Poland, Spain, and Sweden) address inhaler selection with special focus on the Easyhaler® device, a high- or medium-high resistance dry-powder inhaler (DPI). The evidence examined indicates that use of the Easyhaler is associated with effective control of asthma or COPD, as shown by the generally accepted indicators of treatment success. Moreover, the Easyhaler is widely accepted by patients, is reported to be easy to learn and teach, and is associated with patient adherence. These advantages help patient education regarding correct inhaler use and the rational selection of drugs and devices. We conclude that switching inhaler device to the Easyhaler may improve asthma and COPD control without causing any additional risks. In an era of climate change, switching from pressurized metered-dose inhalers to DPIs is also a cost-effective way to reduce emissions of greenhouse gases.

Efficacy of mepolizumab in usual clinical practice and characteristics of responders.

BACKGROUND: Severe eosinophilic asthma is a high-burden disease. Mepolizumab has been effective in several randomized clinical trials. However, such success might not be applicable to patients treated in usual clinical practice. The objectives of this article are to evaluate the efficacy of mepolizumab in severe uncontrolled eosinophilic asthma under usual clinical practice, and to determine characteristics associated with the response to this treatment. METHODS: We have conducted a retrospective, multicentre study, including all adult patients with severe uncontrolled eosinophilic asthma in Galicia, Spain, on whom mepolizumab treatment was started before June 2020, at least 6 months before the time of inclusion, and had received at least one dose of the drug. Patient characteristics, clinical data, respiratory function and comorbidities were collected at baseline and at the 6-month-follow-up. Responders and super-responders were defined according to clinical response and requirement of systemic corticosteroids. RESULTS: 122 patients (mean age 58 years old) were included. In the follow-up treatment 6 months later, 75.4% of the patients were well-controlled, displaying a significant reduction in blood eosinophil counts (p < 0.001), hospital admissions and disease exacerbations (p < 0.001), and had their systemic glucocorticosteroid dose significantly reduced (p < 0.001). The inhaled corticosteroid dose was also lowered (p < 0.01) after 6 months of treatment. Around two-thirds had a clinically significant increase in FEV1, 95% of the patients were considered responders and 43% super-responders. CONCLUSION: In routine clinical practice, mepolizumab is effective in patients with severe eosinophilic asthma and it has a good safety profile.

Prevalence and clinical impact of systemic autoimmune rheumatic disease in patients with silicosis / Prevalencia e impacto clínico de las enfermedades reumatológicas autoinmunitarias sistémicas en pacientes con silicosis

Background: Silicosis is associated with an increased risk of developing systemic autoimmune rheumatic disease (SARD). The prognostic implications of this association are poorly characterized. The aim of this study was to determine the prevalence of SARD and autoimmune markers in a cohort of patients with exposure to silica and assess their impact on prognosis. Method: We performed a prospective observational study of all patients attending the dedicated silicosis clinic of our pulmonology unit between 2009 and December 2017. Diagnosis was confirmed by a rheumatologist according to Spanish Rheumatology Society criteria. Autoimmune markers, pulmonary function tests, radiological progression, visits to the emergency department and primary care center, and hospital admissions for respiratory causes, and mortality were analyzed. Results: Overall, 489 cases of silicosis and 95 cases of exposure were studied. In total, 54 (11.0%) patients with silicosis had SARD: 12 (2.4%) rheumatoid arthritis, 10 (2.0%) systemic lupus erythematosus, 10 (2.0%) systemic sclerosis, 3 (0.6%) Sjögren syndrome, 2 (0.4%) vasculitis associated with anti-neutrophil cytoplasmic antibodies (ANCA +), 6 (1.2%) psoriatic arthritis, 3 (0.6%) ankylosing spondylitis, and 8 (1.6%) other autoimmune diseases with no special features. The patients with SARD visited the emergency room more often (63.0% vs. 42.5%; p = 0.004), and progressed more rapidly (22.2 vs. 11.7%; p = 0.030). Conclusions: The presence of systemic rheumatic autoimmune diseases involves radiological progression and a higher clinical impact. (AU)

El objetivo del estudio es determinar la prevalencia de ERAS y de marcadores de autoinmunidad en una cohorte de pacientes con exposición a inhalación de polvo de sílice y evaluar su impacto clínico. Método: Estudio observacional prospectivo en pacientes atendidos en una consulta monográfica de silicosis desde 2009 hasta diciembre 2017. El diagnóstico de ERAS se confirmó por un especialista en Reumatología según criterios de la Sociedad Española de Reumatología. Se analizaron marcadores de autoinmunidad, pruebas de función respiaratoria, progresión radiológica e impacto clínico medido por visitas a Atención Primaria, a Servicio de Urgencias, ingresos hospitalarios por causa respiratoria y mortalidad. Resultados: Se estudiaron 489 casos de silicosis y 95 de exposición a inhalación de polvo de sílice sin silicosis. De los pacientes con silicosis, 54 (11,0%) tenían ERAS: 12 (2,4%) artritis reumatoide, 10 (2,0%) lupus eritematoso sistémico, 10 (2,0%) esclerosis sistémica, 6 (1,2%) artritis psoriásica, 3 (0,6%) Síndrome de Sjögren, 2 (0,4%) vasculitis asociada a anticuerpos anticitoplasma de neutrófilos, 3 (0,6%) espondiloartritis y 8 (1,6%) enfermedad autoinmune sin características específicas. Los pacientes con ERAS realizaron más visitas a urgencias (63,0% vs. 42,5%; p = 0,004), y experimentaron mayor progresión (22,2 vs. 11,7%; p = 0,030). Conclusiones: Los pacientes con silicosis presentan una prevalencia de ERAS elevada y su presencia se asocia a una mayor progresión radiológica y un mayor impacto clínico. (AU)

Association of the CFTR gene with asthma and airway mucus hypersecretion.

INTRODUCTION: Asthma with airway mucus hypersecretion is an inadequately characterized variant of asthma. While several studies have reported that hypersecreting patients may carry genetic variants in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, many of those studies have been questioned for their numerous limitations and contradictory results. OBJECTIVES: (1) To determine the presence of genetic variants of the CFTR gene in patients with asthma with and without airway mucus hypersecretion. (2) To identify the clinical, inflammatory and functional characteristics of the asthma phenotype with airway mucus hypersecretion. METHOD: Comparative multicentre cross-sectional descriptive study that included 100 patients with asthma (39 hypersecretors and 61 non-hypersecretors). Asthmatic hypersecretion was defined as the presence of cough productive of sputum on most days for at least 3 months in 2 successive years. The patients were tested for fractional exhaled nitric oxide, spirometry, induced sputum cell count, total immunoglobulin E (IgE), peripheral blood eosinophil count, C-reactive protein, blood fibrinogen and blood albumin and underwent a skin prick test. Asthma control and quality of life were assessed by the Asthma Control Test and Mini Asthma Quality of Life questionnaires, respectively. Blood DNA samples were collected from the patients and next-generation sequencing using a MiSeq sequencer and the Illumina platform was used for the CFTR gene analysis. RESULTS: Genetic differences were observed in the c.1680-870T>A polymorphism of the CFTR gene, significantly more evident in hypersecretors than in non-hypersecretors: 78.94% vs. 59.32% in the majority allele and 21.05% vs. 40.67% in the minority allele (p = 0.036). Clinically, asthma hypersecretors compared to non-hypersecretors were older (57.4 years vs. 49.4 years; p = 0.004); had greater asthma severity (58.9% vs. 23.7%; p = 0.005); experienced greater airway obstruction (FEV1/FVC% 64.3 vs. 69.5; p = 0.041); had poorer asthma control (60% vs. 29%; p = 0.021); had lower IgE levels (126.4 IU/mL vs. 407.6 IU/mL; p = 0.003); and were less likely to have a positive prick test (37.5% vs. 68.85%; p = 0.011). CONCLUSION: The results suggest that patients with asthma and with mucus hypersecretion (1) may have a different phenotype and disease mechanism produced by an intronic polymorphism in the CFTR gene (NM_000492.3:c.1680-870T>A), and (2) may have a poorer clinical outcome characterized by severe disease and poorer asthma control with a non-allergic inflammatory phenotype.

Serum levels of inflammatory mediators as prognostic biomarker in silica exposed workers.

Silicosis is a diffuse interstitial lung disease caused by sustained inhalation of silica and silicates. Several cytokines are activated by their inhalation and can mediate the process of pulmonary fibrosis. The identification of biomarkers could allow an early diagnosis before the development of radiological alterations and help monitor the evolution of patients. The objetive of this study was to determine the clinical significance of specific biomarkers, to estimate their association with the development, severity and/or progression of silicosis, and identify determinants of this evolution. We conducted a prospective observational study in patients attending the pulmonology clinic from 2009 to 2018. Serum levels of the following inflammatory mediators were assessed: interleukin-6 (IL-6), interleukin 2 receptor subunit alpha (IL2R) interleukin 1 beta (IL1B), interleukin-8 (IL-8), tumour necrosis factor-alpha (TNF-α), transforming growth factor-beta1 (TGF-ß1), alpha-1 antitrypsin (AAT), C-reactive protein (CRP), lactate dehydrogenase (LDH) and ferritin in subjects exposed to silica, with and without silicosis. Association between those inflammatory mediators with lung function measurements and radiological severity of disease and their impact on prognosis were analysed. 337 exposed to silica (278 with silicosis) and 30 subjects in the control group were included. IL-8, α1AT, ferritin, CRP and LDH levels were higher in silicosis than in those exposed to silica without silicosis. IL-8, LDH and AAT levels were associated with progression of silicosis and IL-6, IL-8, LDH, AAT, ferritin, and CRP with vital status. The results of the ROC analysis indicated the potential of IL-8 as a biomarker in the presence of silicosis and for the prediction of mortality.

Relationship Between Clinical Control, Respiratory Symptoms and Quality of Life for Patients with COPD.

Background: The concept of clinical control has been proposed as an instrument for evaluating patients with COPD. However, the possible association between clinical control, reduced symptom severity and HRQoL has yet to be confirmed. Methods: This multicentre, prospective and observational study was carried out in 15 pulmonology clinics in Spain. The patients were followed up for six months, with a baseline visit (V0), followed by visits at three months (V1) and six months (V2). Clinical control was determined at V1, with the application of both clinical criteria and the COPD assessment test (CAT). All patients reported their symptoms by a validated symptom diary (E-RS) using a portable device, and their HRQoL was assessed using the EQ5D questionnaire. The relationship between clinical control and E-RS and HRQoL during follow-up was assessed with t-test. Results: A total of 126 patients were screened. After application of the inclusion/exclusion criteria, 93 were finally included (mean age 66 ± 8 years, 84.9% male), with a mean FEV1 predicted of 49.8% ± 16.5%. Of these patients, 44 (47.3%) achieved clinical control at V1, according to CAT criteria, and 50 (53.8%), according to clinical criteria. The E-RS scores differed between controlled and uncontrolled patients at all time points, both according to CAT (mean differences of -4.6, -5.6 and -6.2 units at V0, V1 and V2, respectively, p<0.005 for all comparisons) and to clinical criteria (mean differences of -3.3, -5-6 and -4.99 units, respectively, p<0.005 for all comparisons). The controlled patients also presented a significantly better HRQoL, measured by the EQ5D questionnaire (mean difference 0.13 and 0.10 at V2 by CAT or clinical criteria, respectively, p<0.05). Conclusion: Clinical control in patients with COPD, whether measured by CAT or by clinical criteria, is associated with a lower symptom load and a better HRQoL.

Validation of the portable Air-Smart Spirometer.

BACKGROUND: The Air-Smart Spirometer is the first portable device accepted by the European Community (EC) that performs spirometric measurements by a turbine mechanism and displays the results on a smartphone or a tablet. METHODS: In this multicenter, descriptive and cross-sectional prospective study carried out in 2 hospital centers, we compare FEV1, FVC, FEV1/FVC ratio measured with the Air Smart-Spirometer device and a conventional spirometer, and analyze the ability of this new portable device to detect obstructions. Patients were included for 2 consecutive months. We calculate sensitivity, specificity, positive and negative predictive value (PPV and NPV) and likelihood ratio (LR +, LR-) as well as the Kappa Index to evaluate the concordance between the two devices for the detection of obstruction. The agreement and relation between the values of FEV1 and FVC in absolute value and the FEV1/FVC ratio measured by both devices were analyzed by calculating the intraclass correlation coefficient (ICC) and the Pearson correlation coefficient (r) respectively. RESULTS: 200 patients (100 from each center) were included with a mean age of 57 (± 14) years, 110 were men (55%). Obstruction was detected by conventional spirometry in 73 patients (40.1%). Using a FEV1/FVC ratio smaller than 0.7 to detect obstruction with the Air Smart-Spirometer, the kappa index was 0.88, sensitivity (90.4%), specificity (97.2%), PPV (95.7%), NPV (93.7%), positive likelihood ratio (32.29), and negative likelihood ratio (0.10). The ICC and r between FEV1, FVC, and FEV1 / FVC ratio measured by the Air Smart Spirometer and the conventional spirometer were all higher than 0.94. CONCLUSION: The Air-Smart Spirometer is a simple and very precise instrument for detecting obstructive airway diseases. It is easy to use, which could make it especially useful non-specialized care and in other areas.

Mucus hypersecretion in asthma is associated with rhinosinusitis, polyps and exacerbations.

BACKGROUND: Bronchial hypersecretion is a poorly studied symptom in asthma. The aim of the study was to determine the specific characteristics of asthmatics with bronchial hypersecretion. METHODS: A total of 142 asthmatics (21.8% men; mean age 49.8 years) were prospectively followed for one year. Mucus hypersecretion was clinically classified into two severity categories: daily sputum production and frequent expectoration but not every day. Clinical and pulmonary function variables associated with mucus hypersecretion were assessed by multiple logistic regression analysis. RESULTS: Daily cough was recorded in 28.9% of patients and sputum production daily or most of the days in 52.1%. Patients with mucus hypersecretion had more dyspnoea, poorer asthma control and quality of life, had suffered from more exacerbations and showed anosmia associated with chronic rhinosinusitis and nasal polyposis more frequently. Factors associated to mucus hypersecretion were anosmia, one exacerbation or more in the previous year and FEV1/FVC <70% (AUC 0.75, 95% CI 0.66-0.85) for the first definition of hypersecretion, and anosmia, poor asthma control and age (AUC 0.75, 95% CI 0.67-0.83) for the second definition. CONCLUSIONS: Mucus hypersecretion is frequent in patients with asthma, and is associated with chronic upper airways disease, airway obstruction, poor asthma control and more exacerbations.
