RESUMEN

INTRODUCTION: Sleep-disordered breathing (SDB) is a major comorbidity in idiopathic pulmonary fibrosis (IPF) and is associated with a poor outcome. There is a lack of knowledge regarding the impact of SDB treatment on IPF. We assessed at one year: (1) the effect of CPAP and/or nocturnal oxygen therapy on IPF regarding lung function, blood mediators, and quality of life; (2) adherence to SDB treatment and SDB changes. METHODOLOGY: This is a prospective study of consecutive newly diagnosed IPF patients initiating anti-fibrotic treatment. Lung function, polysomnography, blood tests and quality of life questionnaires were performed at inclusion and after one year. Patients were classified as obstructive sleep apnoea (OSA), central sleep apnoea (CSA), and sleep-sustained hypoxemia (SSH). SDB therapy (CPAP and/or nocturnal oxygen therapy) was initiated if needed. RESULTS: Fifty patients were enrolled (36% had OSA, 22% CSA, and 12% SSH). CPAP was started in 54% of patients and nocturnal oxygen therapy in 16%. At one-year, polysomnography found improved parameters, though 17% of patients had to add nocturnal oxygen therapy or CPAP, while 33% presented SDB onset at this second polysomnography. CPAP compliance at one year was 6.74 h/night (SD 0.74). After one year, matrix metalloproteinase-1 decreased in OSA and CSA (p = 0.029; p = 0.027), C-reactive protein in OSA (p = 0.045), and surfactant protein D in CSA group (p = 0.074). There was no significant change in lung function. CONCLUSIONS: Treatment of SBD with CPAP and NOT can be well tolerated with a high compliance. IPF patients may exhibit SDB progression and require periodic re-assessment. Further studies to evaluate the impact of SDB treatment on lung function and serological mediators are needed.

RESUMEN

Fibrosing interstitial lung diseases (FILDs), e.g., due to idiopathic pulmonary fibrosis (IPF), are chronic progressive diseases with a poor prognosis. The management of these diseases is challenging and focuses mainly on the suppression of progression with anti-fibrotic drugs. Therefore, novel FILD treatments are needed. In recent years, cell-based therapy with various stem cells has been investigated for FILD, and the use of mesenchymal stem cells (MSCs) has been widely reported and clinical studies are also ongoing. Induced pluripotent stem cells (iPSCs) have also been reported to have an anti-fibrotic effect in FILD; however, these have not been as well studied as MSCs in terms of the mechanisms and side effects. While MSCs show a potent anti-fibrotic effect, the possibility of quality differences between donors and a stable supply in the case of donor shortage or reduced proliferative capacity after cell passaging needs to be considered. The application of iPSC-derived cells has the potential to overcome these problems and may lead to consistent quality of the cell product and stable product supply. This review provides an overview of iPSCs and FILD, followed by the current status of cell-based therapy for FILD, and then discusses the possibilities and perspectives of FILD therapy with iPSC-derived cells.

RESUMEN

OBJECTIVE: To evaluate the extracorporeal membrane oxygenation (ECMO) related outcomes during hospitalization during the intensive care unit (ICU) in idiopathic pulmonary fibrosis (IPF) patients with high body mass index (BMI, > 25 kg/m2) undergoing lung transplantation with ECMO support. METHODS: A retrospective observational study was conducted. IPF patients who received ECMO during lung transplantation admitted to the Affiliated Wuxi People's Hospital of Nanjing Medical University from 2019 to 2020 were enrolled. Preoperative indicators including, demographics, comorbidities, arterial blood gas, and laboratory indicators; intraoperative indicators, such as lung lobe volume reduction, surgical type, surgical time, cold ischemia time, blood loss and transfusion volume; immediate indicators upon admission to the ICU, such as blood gas analysis and laboratory indicators; ECMO related outcomes, such as ECMO mode, ECMO support time, ECMO related complications (bleeding at the catheterization site, intraductal thrombosis, lower limb ischemia), and the length of ICU stay, duration of mechanical ventilation, and 30-day survival rate were collected. According to BMI, patients were divided into three groups: light weight group (BMI < 18.5 kg/m2), normal weight group (BMI 18.5-24.9 kg/m2), and overweight group (BMI ≥ 25.0 kg/m2). Mainly to compare the relevant outcomes of ECMO among patients during ICU. RESULTS: A total of 114 IPF patients who received ECMO support during lung transplantation were collected, including 23 cases in the light weight group, 63 cases in the normal weight group, and 28 cases in the overweight group. Compared with patients with underweight and normal weight, overweight patients were more likely to have hypertension (46.4% vs. 8.7%, 23.8%, P < 0.01) and coronary heart disease (32.1% vs. 4.3%, 20.6%, P < 0.05) before surgery, which was consistent with international guidelines for obesity. Other clinical data (preoperative, intraoperative, ICU characteristics) showed no statistically significant differences and were comparable. There was no statistically significant difference in terms of ECMO related outcomes, such as ECMO related complications [veno-venous (V-V) mode: 78.3%, 77.8%, 78.6%, veno-arterial (V-A) mode: 21.7%, 22.2%, 21.4%], ECMO support time (hours: 61.70±20.03, 44.57±5.76, 41.77±7.26), ECMO related complications (bleeding at the catheterization site: 4.3%, 7.9%, 14.3%; intraductal thrombosis: 8.7%, 12.7%, 17.9%; lower limb ischemia: 8.7%, 12.7%, 14.3%), and the length of ICU stay (days: 11±3, 7±1, 9±1), duration of mechanical ventilation [days: 2 (2, 11), 2 (2, 6), 3 (2, 8)] among the light weight group, normal weight group, and overweight group (all P > 0.05). Kaplan-Meier survival curve analysis showed that there was no statistically significant difference in the 30-day cumulative survival rate among the three groups (Log-Rank test: χ 2 = 0.919, P = 0.632). CONCLUSIONS: High BMI does not worsen ECMO-related outcomes or adversely affect early prognosis in IPF patients undergoing lung transplantation. BMI as a single parameter should not be a contraindication for the use of ECMO in lung transplantation surgery for IPF patients.

RESUMEN

The American Thoracic Society/European Respiratory Society/Japanese Respiratory Society/Asociación Latinoamericana de Tórax 2018 clinical practice guideline and 2022 update provide recommendations to define and diagnose idiopathic pulmonary fibrosis (IPF) in patients with newly diagnosed interstitial lung disease. The guideline emphasizes recognition of usual interstitial pneumonia (UIP) and probable UIP patterns of fibrosis on high-resolution CT, which can obviate the need for surgical lung biopsy and allow timely initiation of antifibrotic pharmacotherapy citing a high correlation with UIP on histopathology. This article reviews the recent 2022 IPF clinical practice guideline with a focus on the imaging updates.

RESUMEN

BACKGROUND: Interstitial lung diseases (ILD) are a heterogenous group of over 200 disorders affecting the pulmonary interstitium. Although there have been advances in knowledge on ILDs in Australia, the characterisation of the health and economic burden of disease remained largely undetermined until recently. OBJECTIVE: The main objective of this review is to provide a synopsis of health and economic burden of ILDs in Australia, based on recently completed research. DISCUSSION: Recent research has demonstrated that idiopathic pulmonary fibrosis (IPF) is the most frequent ILD in Australia. Incidence and prevalence of IPF have demonstrated an increasing trend over the past decades. Mortality has also increased over the past decades, but has shown a slight decreasing trend recently, since the introduction of antifibrotic medication. Health-related quality of life is poor in patients with IPF, and care is estimated to cost approximately AU$299 million per year in Australia. Early diagnosis and referral to tertiary care is crucial for favourable outcomes, and general practitioners are considerably important to this as the first interface to identify patients at risk and detect early symptoms of ILDs.

RESUMEN

MicroRNAs (miRNAs) are short, non-coding single-stranded RNA molecules approximately 22 nucleotides in length, intricately involved in post-transcriptional gene expression regulation. Over recent years, researchers have focused keenly on miRNAs, delving into their mechanisms in various diseases such as cancers. Among these, miR-26a emerges as a pivotal player in respiratory ailments such as pneumonia, idiopathic pulmonary fibrosis, lung cancer, asthma, and chronic obstructive pulmonary disease. Studies have underscored the significance of miR-26a in the pathogenesis and progression of respiratory diseases, positioning it as a promising therapeutic target. Nevertheless, several challenges persist in devising medical strategies for clinical trials involving miR-26a. In this review, we summarize the regulatory role and significance of miR-26a in respiratory diseases, and we analyze and elucidate the challenges related to miR-26a druggability, encompassing issues such as the efficiency of miR-26a, delivery, RNA modification, off-target effects, and the envisioned therapeutic potential of miR-26a in clinical settings.

RESUMEN

Importance: Interstitial lung disease (ILD) consists of a group of pulmonary disorders characterized by inflammation and/or fibrosis of the lung parenchyma associated with progressive dyspnea that frequently results in end-stage respiratory failure. In the US, ILD affects approximately 650 000 people and causes approximately 25 000 to 30 000 deaths per year. Observations: The most common forms of ILD are idiopathic pulmonary fibrosis (IPF), which accounts for approximately one-third of all cases of ILD, hypersensitivity pneumonitis, accounting for 15% of ILD cases, and connective tissue disease (CTD), accounting for 25% of ILD cases. ILD typically presents with dyspnea on exertion. Approximately 30% of patients with ILD report cough. Thoracic computed tomography is approximately 91% sensitive and 71% specific for diagnosing subtypes of ILDs such as IPF. Physiologic assessment provides important prognostic information. A 5% decline in forced vital capacity (FVC) over 12 months is associated with an approximately 2-fold increase in mortality compared with no change in FVC. Antifibrotic therapy with nintedanib or pirfenidone slows annual FVC decline by approximately 44% to 57% in individuals with IPF, scleroderma associated ILD, and in those with progressive pulmonary fibrosis of any cause. For connective tissue disease-associated ILD, immunomodulatory therapy, such as tocilizumab, rituximab, and mycophenolate mofetil, may slow decline or even improve FVC at 12-month follow-up. Structured exercise therapy reduces symptoms and improves 6-minute walk test distance in individuals with dyspnea. Oxygen reduces symptoms and improves quality of life in individuals with ILD who desaturate below 88% on a 6-minute walk test. Lung transplant may improve symptoms and resolve respiratory failure in patients with end-stage ILD. After lung transplant, patients with ILD have a median survival of 5.2 to 6.7 years compared with a median survival of less than 2 years in patients with advanced ILD who do not undergo lung transplant. Up to 85% of individuals with end-stage fibrotic ILD develop pulmonary hypertension. In these patients, treatment with inhaled treprostinil improves walking distance and respiratory symptoms. Conclusions and Relevance: Interstitial lung disease typically presents with dyspnea on exertion and can progress to respiratory failure. First-line therapy includes nintedanib or pirfenidone for IPF and mycophenolate mofetil for ILD due to connective tissue disease. Lung transplant should be considered for patients with advanced ILD. In patients with ILD, exercise training improves 6-minute walk test distance and quality of life.

RESUMEN

INTRODUCTION: Progressive pulmonary Fibrosis Abstract: Cough and dyspnea on excertion are common and early symptoms of interstitial lung diseases (ILD). Thoracic imaging (particularly computed tomography) detects such lung structural alterations early in the disease course. Knowledge of these diseases and their management is necessary in the daily business. The term "progressive pulmonary fibrosis" subsumes a heterogene group of interstitial lung diseases with a similar course of progressive fibrosis. The management of these diseases should be discussed interdisciplinary, similar to the management of the Idiopathic pulmonary fibrosis (IPF). Antifibrotic drugs are new therapeutic options.

RESUMEN

Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease with a poor prognosis and an unknown cause that generally progresses to pulmonary fibrosis and leads to irreversible tissue alteration. The "Guidelines for the treatment of idiopathic pulmonary fibrosis 2017," specializing in the treatment of IPF for the first time in Japan and presenting evidence-based standard treatment methods suited to the state of affairs in Japan, was published in 2017, in line with the 2014 version of "Formulation procedure for Minds Clinical Practice Guidelines." Because new evidence had accumulated, we formulated the "Guidelines for the treatment of Idiopathic Pulmonary Fibrosis 2023 (revised 2nd edition)." While keeping the revision consistent with the ATS/ERS/JRS/ALAT IPF treatment guidelines, new clinical questions (CQs) on pulmonary hypertension were added to the chronic stage, in addition to acute exacerbation and comorbid lung cancer, which greatly affect the prognosis but are not described in the ATS/ERS/JRS/ALAT IPF guidelines. Regarding the advanced stages, we additionally created expert consensus-based advice for palliative care and lung transplantation. The number of CQs increased from 17 in the first edition to 24. It is important that these guidelines be used not only by respiratory specialists but also by general practitioners, patients, and their families; therefore, we plan to revise them appropriately in line with ever-advancing medical progress.

RESUMEN

BACKGROUND: Approximately 50% of patients with interstitial lung disease (ILD) experience frailty, which remains unexplored in acute exacerbations of ILD (AE-ILD). A better understanding may help with prognostication and resource planning. We evaluated the association of frailty with clinical characteristics, physical function, hospital outcomes, and post-AE-ILD recovery. METHODS: Retrospective cohort study of AE-ILD patients (01/2015-10/2019) with frailty (proportion ≥0.25) on a 30-item cumulative-deficits index. Frail and non-frail patients were compared for pre- and post-hospitalization clinical characteristics, adjusted for age, sex, and ILD diagnosis. One-year mortality, considering transplantation as a competing risk, was analysed adjusting for age, frailty, and Charlson Comorbidity Index (CCI). RESULTS: 89 AE-ILD patients were admitted (median: 67 years, 63% idiopathic pulmonary fibrosis). 31 were frail, which was associated with older age, greater CCI, lower 6-min walk distance, and decreased independence pre-hospitalization. Frail patients had more major complications (32% vs 10%, p = .01) and required more multidisciplinary support during hospitalization. Frailty was not associated with 1-year mortality (HR: 0.97, 95%CI: [0.45-2.10]) factoring transplantation as a competing risk. CONCLUSIONS: Frailty was associated with reduced exercise capacity, increased comorbidities and hospital complications. Identifying frailty may highlight those requiring additional multidisciplinary support, but further study is needed to explore whether frailty is modifiable with AE-ILD.

RESUMEN

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive and fatal lung disease of which the origin and development mechanisms remain unknown. The few available pharmacological treatments can only slow the progression of the disease. The development of curative treatments is hampered by the absence of experimental models that can mimic the specific pathophysiological mechanisms of IPF. The aim of this mini-review is to provide an overview of the most commonly used experimental animal models in the study of IPF and to underline the urgent need to seek out new, more satisfactory models.

RESUMEN

Idiopathic pulmonary fibrosis (IPF) is a continuous, progressive, and lethal age-related respiratory disease. It is characterized by condensed and rigid lung tissue, which leads to a decline in the normal functioning of the lungs. The pathophysiology of IPF has still not been completely elucidated, so current strategies are lagging behind with respect to improving the condition of patients with IPF and increasing their survival rate. The desire for a better understanding of the pathobiology of IPF and its early detection has led to the identification of various biomarkers associated with IPF. The use of drugs such as pirfenidone and nintedanib as a safe and effective treatment alternative have marked a new chapter in the treatment of IPF. However, nonpharmacological therapies, involving long-term oxygen therapy, transplantation of the lungs, pulmonary rehabilitation, ventilation, and palliative care for cough and dyspnea, are still considered to be beneficial as supplementary methods for IPF therapy. A major risk factor for IPF is aging, with associated hallmarks such as telomere attrition, senescence, epigenetic drift, stem cell exhaustion, loss of proteostasis, and mitochondrial dysfunction. These are promising earmarks for the development of potential therapy for the disease. In this review, we have discussed current and emerging novel therapeutic strategies for IPF, especially for targets associated with age-related mechanisms.

RESUMEN

BACKGROUND/AIMS: The prognosis of patients with idiopathic pulmonary fibrosis (IPF) and respiratory failure requiring mechanical ventilation is poor. Therefore, mechanical ventilation is not recommended. Recently, outcomes of mechanical ventilation, including those for patients with IPF, have improved. The aim of this study was to investigate changes in the use of mechanical ventilation in patients with IPF and their outcomes over time. METHODS: This retrospective, observational cohort study used data from the National Health Insurance Service database. Patients diagnosed with IPF between January 2011 and December 2019 who were placed on mechanical ventilation were included. We analyzed changes in the use of mechanical ventilation in patients with IPF and their mortality using the Cochran- Armitage trend test. RESULTS: Between 2011 and 2019, 1,227 patients with IPF were placed on mechanical ventilation. The annual number of patients with IPF with and without mechanical ventilation increased over time. However, the ratio was relatively stable at approximately 3.5%. The overall hospital mortality rate was 69.4%. There was no improvement in annual hospital mortality rate. The overall 30-day mortality rate was 68.7%, which did not change significantly. The overall 90-day mortality rate was 85.3%. The annual 90-day mortality rate was decreased from 90.9% in 2011 to 83.1% in 2019 (p = 0.028). CONCLUSION: Despite improvements in intensive care and ventilator management, the prognosis of patients with IPF receiving mechanical ventilation has not improved significantly.

RESUMEN

Background: Idiopathic pulmonary fibrosis (IPF) is a severe interstitial lung disease characterized by chronic lung injury leading to macrophage infiltration and fibroblast activation. However, there is no effective therapeutic strategy targeting the crucial crosstalk between macrophages and fibroblasts to halt IPF progression. Methods: Studies were conducted in IPF patients and fibrotic mice models to elucidate the role of Bcar3 in the pathogenesis of pulmonary fibrosis. The effect of Bcar3 on macrophage polarization, fibroblast activation, and related signaling pathways were next investigated to unravel the underlying mechanisms. Results: Our study elucidates a marked increase in Bcar3 expression in lung tissues from IPF patients and fibrotic mice, recording 1.7 and 7.8-fold increases compared to control subjects, respectively. Additionally, Bcar3 was found to significantly enhance macrophage activation and fibroblast differentiation, observable in both in vivo and in vitro settings. Mechanistically, the upregulation of Bcar3 in macrophages was reliant on Stat6, while in fibroblasts, it depended on TGFßR1/Smad3. Furthermore, Bcar3 augmented IL-4/Stat6 pathway in macrophages and TGF-ß/Smad3 pathway in fibroblasts, supporting a synergistic activation loop that expedited lung fibrogenesis. Notably, intratracheal injection of liposomes containing Bcar3 siRNA precisely delivered gene therapeutics to lung macrophages and fibroblasts, effectively reducing Bcar3 expression to 59% of baseline levels. Importantly, this intervention protected mice from lung fibrosis induced by either FITC or bleomycin, as well as human precision-cut lung slices against TGF-ß1 stimulation. Conclusion: Our study underscores the pivotal role of Bcar3 in orchestrating the macrophage-fibroblast crosstalk during pulmonary fibrosis progression. Targeting Bcar3 emerges as a novel therapeutic avenue to halt IPF progression and enhance patient prognosis.

RESUMEN

Idiopathic pulmonary fibrosis (IPF) is a progressive scarring disease of the lung that leads rapidly to respiratory failure. Novel approaches to treatment are urgently needed. The bioactive lipid sphingosine-1-phosphate (S1P) is increased in IPF lungs and promotes proinflammatory and profibrotic TGF-ß signaling. Hence, decreasing lung S1P represents a potential therapeutic strategy for IPF. S1P is degraded by the intracellular enzyme S1P lyase (SPL). Here we find that a knock-in mouse with a missense SPL mutation mimicking human disease resulted in reduced SPL activity, increased S1P, increased TGF-ß signaling, increased lung fibrosis, and higher mortality after injury compared to wild type (WT). We then tested adeno-associated virus 9 (AAV9)-mediated overexpression of human SGPL1 (AAV-SPL) in mice as a therapeutic modality. Intravenous treatment with AAV-SPL augmented lung SPL activity, attenuated S1P levels within the lungs, and decreased injury-induced fibrosis compared to controls treated with saline or only AAV. We confirmed that AAV-SPL treatment led to higher expression of SPL in the epithelial and fibroblast compartments during bleomycin-induced lung injury. Additionally, AAV-SPL decreased expression of the profibrotic cytokines TNFα and IL1ß as well as markers of fibroblast activation, such as fibronectin (Fn1), Tgfb1, Acta2, and collagen genes in the lung. Taken together, our results provide proof of concept for the use of AAV-SPL as a therapeutic strategy for the treatment of IPF. © 2024 The Authors.

RESUMEN

AIMS: Patients diagnosed with idiopathic pulmonary fibrosis (IPF) have a high symptom burden and numerous needs that remain largely unaddressed despite advances in available treatment options. There is a need to comprehensively identify patients' needs and create opportunities to address them. This scoping review aimed to synthesise the available evidence and identify gaps in the literature regarding the unmet needs of patients diagnosed with IPF. METHODS: The protocol for the review was registered with Open Science Framework (DOI 10.17605/OSF.IO/SY4KM). A systematic search was performed in March 2022, in CINAHL, MEDLINE, Embase, PsychInfo, Web of Science Core Collection and ASSIA Applied Social Science Index. A comprehensive review of grey literature was also completed. Inclusion criteria included patients diagnosed with IPF and date range 2011-2022. A range of review types were included. Data was extracted using a data extraction form. Data was analysed using descriptive and thematic analysis. A total of 884 citations were reviewed. Ethical approval was not required. RESULTS: 52 citations were selected for final inclusion. Five themes were identified: 1.) psychological impact of an IPF diagnosis. 2.) adequate information and education: at the right time and in the right way. 3.) high symptom burden support needs. 4.) referral to palliative care and advance care planning (ACP). 5.) health service provision-a systems approach. CONCLUSION: This review highlights the myriad of needs patients with IPF have and highlights the urgent need for a systems approach to care, underpinned by an appropriately resourced multi-disciplinary team. The range of needs experienced by patients with IPF are broad and varied and require a holistic approach to care including targeted research, coupled with the continuing development of patient-focused services and establishment of clinical care programmes.

RESUMEN

Pulmonary arterial hypertension (PAH), idiopathic pulmonary fibrosis (IPF), and scleroderma (SSc) are three interrelated medical conditions that can result in significant morbidity and mortality. Pulmonary hypertension, a condition marked by high blood pressure in the lungs, can lead to heart failure and other complications. Idiopathic pulmonary fibrosis, a progressive lung disease characterised by scarring of lung tissue, can cause breathing difficulties and impaired oxygenation. Scleroderma, an autoimmune disease, can induce thickening and hardening of the skin and internal organs, including the lungs, leading to pulmonary fibrosis and hypertension. Currently, there is no cure for any of these conditions. However, early detection and proper management can improve the quality of life and prognosis of a patient. This review focusses on PH and IPF in patients with SSc, providing information on the causes, symptoms, and treatment of these conditions, together with illustrative images. It also provides an overview of interrelated medical conditions: PH, IPF, and SSc. It emphasises the importance of early detection and proper management to improve patient quality of life and prognosis.

RESUMEN

The notable advances in interstitial lung disease (ILD) published in Chinese and international authoritative journals from November 2022 to October 2023 were systematically reviewed in our annual review. The year 2023 brought significant advances about mechanism, diagnosis and treatment of idiopathic pulmonary fibrosis, connective tissue diseases associated ILD, sarcoidosis, progressive pulmonary fibrosis and rare ILDs. The related global and/or Chinese commentaries and guidelines were also reviewed in our paper. We also highlighted the important findings of epidemiologic and health economic data on idiopathic pulmonary fibrosis and sarcoidosis.

RESUMEN

Despite progress in elucidation of disease mechanisms, identification of risk factors, biomarker discovery, and the approval of two medications to slow lung function decline in idiopathic pulmonary fibrosis and one medication to slow lung function decline in progressive pulmonary fibrosis, pulmonary fibrosis remains a disease with a high morbidity and mortality. In recognition of the need to catalyze ongoing advances and collaboration in the field of pulmonary fibrosis, the NHLBI, the Three Lakes Foundation, and the Pulmonary Fibrosis Foundation hosted the Pulmonary Fibrosis Stakeholder Summit on November 8-9, 2022. This workshop was held virtually and was organized into three topic areas: 1) novel models and research tools to better study pulmonary fibrosis and uncover new therapies, 2) early disease risk factors and methods to improve diagnosis, and 3) innovative approaches toward clinical trial design for pulmonary fibrosis. In this workshop report, we summarize the content of the presentations and discussions, enumerating research opportunities for advancing our understanding of the pathogenesis, treatment, and outcomes of pulmonary fibrosis.

RESUMEN

Objetivo desarrollar una lista de comprobación para facilitar la atención farmacéutica al paciente con enfermedad pulmonar intersticial que requieren o están en tratamiento con antifibróticos. Método 5 especialistas en farmacia hospitalaria desarrollaron un listado inicial de 37 ítems divididos en 4 bloques: 1) primera visita del paciente, que incluía datos generales del paciente y datos del primer tratamiento; 2) visitas de seguimiento, valorando aspectos del seguimiento del tratamiento con nintedanib o pirfenidona; 3) telefarmacia, consistente en la evaluación de la inclusión de pacientes en un programa de este tipo, evolución de la enfermedad e identificación del contacto con el servicio de farmacia y 4) tratamiento no farmacológico e información al paciente. Para decidir su potencial inclusión en el listado de comprobación se realizaron 2 rondas del Delphi en las que los panelistas tenían que valorar de cada ítem propuesto su grado de acuerdo con su «utilidad», que fue el criterio determinante para su inclusión y su «aplicabilidad». Resultados se contactó con 48 farmacéuticos hospitalarios, 30 (63%) aceptaron por escrito participar, 28 (58%) completaron la primera ronda del Delphi y 27 (56%) completaron la segunda ronda. Después de la primera ronda el cuestionario se modificó y quedó constituido por 40 ítems. De los 40 ítems evaluados tras las 2 rondas del Delphi, hubo 2 que, basados en la utilidad, los participantes del Delphi no alcanzaron el consenso para su inclusión en el listado: el referido a «Antecedentes de intervención quirúrgica, específicamente cirugía abdominal en las últimas 4 semanas» (finalmente mantenido en el listado por su implicación en la indicación de nintedanib) y el de realizar recomendaciones sobre «Relajación». En 2 de los ítems no se alcanzó consenso sobre su aplicabilidad: «Estratificación del paciente según el modelo del paciente crónico de la SEFH» y «Recogida de resultados comunicados por el paciente». Conclusiones... (AU)


Objective To develop a checklist to facilitate pharmaceutical care for patients with interstitial lung disease who require or are undergoing treatment with antifibrotic drugs. Method Five hospital pharmacists developed an initial list of 37 items divided into 4 blocks: 1) First visit, which included general patient data and data from the first treatment; 2) Follow-up visits, assessing aspects of the follow-up of the treatment with nintedanib or pirfenidone; 3) Telepharmacy, consisting of the evaluation of the inclusion of patients in a program of this type, course of the disease, and identification of the contact with the pharmacy service; 4) Non-pharmacological treatment and patient information. To decide its potential inclusion in the checklist, two rounds of the Delphi were carried out in which the panelists had to assess the degree of agreement of each proposed item according to its “utility”, which was the determining criterion for its inclusion, and its “applicability”. Results 48 hospital pharmacists were contacted, 30 (63%) agreed in writing to participate, 28 (58%) completed the first round of the Delphi, and 27 (56%) completed the second round. After the first round of the Delphi the questionnaire was amended and comprised 40 items. Of the 40 items evaluated after the two rounds of the Delphi, there were two that, based on utility, the participants did not reach consensus for inclusion in the checklist: The one referring to “History of surgical intervention, specifically abdominal surgery in the last 4 weeks” (finally kept on the checklist due to its involvement in the indication of nintedanib) and to make recommendations on “Relaxation”. No consensus was reached on their applicability for two of the items: “Patient stratification according to the Spanish Society of Hospital Pharmacy (SEFH) chronic patient model” and “Collection of Results Reported by the Patient”.
