Radiological usual interstitial pneumonia pattern is associated with two-year mortality in patients with idiopathic pulmonary fibrosis.

Introduction: The new diagnostic guidelines for idiopathic pulmonary fibrosis (IPF) did not rule out the possibility of combining the radiological patterns of usual interstitial pneumonia (UIP) and probable UIP, given the similar management and diagnostic capacity. However, the prognostic implications of these patterns have not been fully elucidated, with different studies showing heterogeneous results. We applied the new criteria to a retrospective series of patients with IPF, assessing survival based on radiological patterns, findings, and their extension.

Mosaic attenuation in non-fibrotic areas as a predictor of non-usual interstitial pneumonia pathologic diagnosis.

The new radiological diagnostic criteria for diagnosing idiopathic pulmonary fibrosis (IPF) seek to optimize the indications for surgical lung biopsy (SLB). We applied the new criteria to a retrospective series of patients with interstitial lung disease (ILD) who underwent SLB in order to analyse the correlation between the radiological findings suggestive of another diagnosis (especially mosaic attenuation and its location with respect to fibrotic areas) and the usual interstitial pneumonia (UIP) pathologic diagnosis. Two thoracic radiologists reviewed the HRCT images of 83 patients with ILD and SLB, describing the radiological findings and patterns based on the new criteria.

Prediction of three-month readmission based on haematological parameters in patients with severe COPD exacerbation.

Introduction: Approximately one-third of patients hospitalised for an exacerbation of chronic obstructive pulmonary disease (COPD) are readmitted to the hospital within 90 days. It is of interest to identify biomarkers that predict relapse in order to prevent readmission in these patients. In our prospective study of patients admitted for COPD exacerbation, we aimed to analyse whether routine haematological parameters can help predict the three-month readmission risk.

Application of validated severity scores for pneumonia caused by SARS-CoV-2.

Objectives: Compare the accuracy of PSI, CURB-65, MuLBSTA and COVID-GRAM prognostic scores to predict mortality, the need for invasive mechanical ventilation (IMV) in patients with pneumonia caused by SARS-CoV-2 and assess the coexistence of bacterial respiratory tract infection during admission.

Methods: Retrospective observational study that included hospitalized adults with pneumonia caused by SARS-CoV-2 from 15/03 to 15/05/2020. We excluded immunocompromised patients, nursing home residents and those admitted in the previous 14 days for another reasons.

Symptoms in patients with asthma infected by SARS-CoV-2.

Introduction: Organ tropism of SARS-CoV-2 to the respiratory tract could potentially aggravate asthma. The susceptibility of patients with asthma to develop an exacerbation when they are infected with SARS-CoV-2 is unknown. We aimed to investigate the symptoms presented in patients with asthma who became infected with SARS-CoV-2.

Granulomatous lymphocytic interstitial lung disease: description of a series of 9 cases.

Introduction: Granulomatous-lymphocytic interstitial lung disease (GLILD) is one of the most serious non-infectious complications in patients with common variable immunodeficiency (CVID). Its diagnosis and treatment are challenging.

Objective: To analyse the characteristics of Hospital General Universitario de Alicante patients with CVID and GLILD.
