THIS is the first time that a bronchoalveolar lavage (BAL) neutrophil-to-lymphocyte ratio (NL-ratio) has been demonstrated in sarcoidosis and chronic hypersensitivity pneumonitis (cHP) than in idiopathic pulmonary fibrosis (IPF) patients. ⋯ This is the first time that a lower NL-ratio has been demonstrated in sarcoidosis and cHP than in IPF patients. The present preliminary report indicates a relationship between BAL NL-ratio and lung function parameters in patients with IPF: this ratio may help to optimize management of IPF patients and to improve follow-up and outcome.

Chronic inflammatory responses in the lung of patients with stable mild-to-severe forms of chronic obstructive pulmonary disease (COPD) play a central role in the definition, comprehension and monitoring of the disease state. A better understanding of the COPD pathogenesis cannot avoid a detailed knowledge of these inflammatory changes, altering the functional health of the lung during the disease progression. ⋯ The differential inflammatory distribution in large and small airways of patients is also discussed. Furthermore, relevant cellular mechanisms controlling the homeostasis and the "normal" balance of these inflammatory cells and of structural cells in the lung, such as autophagy, apoptosis, necroptosis and pyroptosis are as well presented and discussed in the context of the COPD severity.

Review Case Reports
Beyond the lung involvement in COVID-19 patients. A review.
Since COVID-19 spread all over the world becoming a pandemic illness, researchers have better characterized route of virus transmissibility and clinical signs and symptoms of the disease. Since viral transmission occurs through the droplets emitted during coughing or sneezing, the lungs are primarily affected. ⋯ This review focuses on extra pulmonary involvement underlying atypical presentation of COVID-19. There is a great body of evidence concerning several human organ abnormalities associated to the SARS-CoV-2, enough to consider COVID-19 as a multisystemic and polyhedral disease.

Lung cancer (LC) and chronic obstructive pulmonary disease (COPD) represent leading causes of morbidity and mortality worldwide. Common risk factors lead to an increased inflammatory response, enhances oxidative stress, and changes in lung microenvironment contributing to fine-tuned interaction between these respiratory disorders. ⋯ Better understanding LC and COPD coexistence may impact on clinical scenario influencing therapeutic approach. In this review, we describe the basis of this network and how the complex interplay between these respiratory disorders affects the clinical decision-making process.

The aim of this study was to evaluate the prognostic value of perinuclear antineutrophil cytoplasmic antibodies (p-ANCA) in subjects with primary sclerosing cholangitis (PSC) and in particular whether it is associated with inflammatory bowel disease (IBD). ⋯ IBD, or especially UC, is present in85% of patients with CSP and p-ANCA positivity, whereas 95% of patients with PSC who test negative for p-ANCA do not have IBD.
