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 characteristic features of chronic obstructive pulmonary disease (COPD) include inflammation and remodeling of the lower airways and lung parenchyma together with activation of inflammatory and immune processes. Due to the increasing habit of cigarette smoking worldwide COPD prevalence is increasing globally. Current therapies are unable to prevent COPD progression in many patients or target many of its hallmark characteristics which may reflect the lack of adequate biomarkers to detect the heterogeneous clinical and molecular nature of COPD. ⋯ We also highlight the evidence for new drugs or approaches to treat COPD identified using molecular and other approaches including kinase inhibitors, cytokine- and chemokine-directed biologicals and small molecules, anti-oxidants and redox signaling pathway inhibitors, inhaled anti-infectious agents and senolytics. It is important to consider the phenotypes/molecular endotypes of COPD patients together with specific outcome measures to target new therapies to particular COPD subtypes. This will require greater understanding of COPD molecular pathologies and a focus on biomarkers of predicting disease subsets and responder/non-responder populations.

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.

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.
