Bronchoalveolar Lavage Complements Transbronchial Cryobiopsy Diagnosis in Diffuse Interstitial Lung Diseases.

BACKGROUND: Bronchoalveolar lavage (BAL) is a technique classically used for the study of diffuse interstitial lung diseases (DILDs). Given the recent advances in the diagnosis of DILD by transbronchial cryobiopsy (TBCB), it is relevant to assess what BAL can contribute to TBCB. PATIENTS AND METHODS: This is a retrospective descriptive study that included patients with DILD who, between 2013 and 2017, underwent BAL and TBCB in the same bronchoscopy intervention. We evaluated the complementary information provided by BAL to TBCB that facilitated the diagnosis by a multidisciplinary committee. Epidemiological, clinical, and functional variables and high-resolution chest tomography findings were recorded, along with complications associated with the procedures. RESULTS: A total of 60 patients were included. TBCB, conditioned by the underlying radiologic pattern, provided diagnostic information in 75% of cases. BAL provided complementary information that supported the diagnosis and treatment in 22% of cases. Differential BAL findings were related to microbiology, cell count, and immunology. Regarding the safety of the procedure, 47% of the patients experienced complications, although none were serious. CONCLUSION: BAL findings contribute to TBCB findings in the diagnosis of DILDs, with no serious complications associated with their combined use.

Comorbidities, Complications and Non-Pharmacologic Treatment in Idiopathic Pulmonary Fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive and fatal disease. The treatment is challenging and nowadays a comprehensive approach based not only in pharmacological strategies is necessary. Identification and control of comorbidities, non-pharmacological treatment, prevention and management of exacerbations as well as other areas of care (social, psychological) are fundamental for a holistic management of IPF. Gastroesophageal reflux, pulmonary hypertension, obstructive sleep apnea, combined with emphysema, lung cancer and cardiovascular involvement are the main comorbidities associated with IPF. Non-pharmacological treatment includes the use of oxygen in patients with rest or nocturnal hypoxemia and other support therapies such as non-invasive ventilation or even a high-flow nasal cannula to improve dyspnea. In some patients, lung transplant should be considered as this enhances survival. Pulmonary rehabilitation can add benefits in outcomes such control of dyspnea, exercise capacity distance and, overall, improve the quality of life; therefore it should be considered in patients with IPF. Also, multidisciplinary palliative care programs could help with symptom control and psychological support, with the aim of maintaining quality of life during the whole process of the disease. This review intends to provide clear information to help those involved in IPF follow up to improve patients' daily care.
