Is Pulmonary Involvement a Distinct Phenotype of Post-COVID-19?

(1) Background: COVID-19 infection often provokes symptoms lasting many months: most commonly fatigue, dyspnea, myalgia and mental distress symptoms. In this study, we searched for clinical features of post-COVID-19 condition (PCC) and differences between patients with and without pulmonary involvement. (2) Methods: A total of 282 patients with a mean age of 57 years (SD +/- 12 years) underwent assessment up to 12 weeks after COVID-19 recovery.

Oxidative Biomarkers Associated with the Pulmonary Manifestation of Post-COVID-19 Complications.

Introduction: The role of mitochondria in post coronavirus disease 2019 (post-COVID-19) complications is unclear, especially in the long-term pulmonary complications. This study aims to investigate the association between post-COVID-19 pulmonary complications and mitochondrial regulatory proteins in the context of oxidative stress.

Methodology: Patients who had recovered from COVID-19 were enrolled.

Soluble ITGaM and ITGb2 Integrin Subunits Are Involved in Long-Term Pulmonary Complications after COVID-19 Infection.

(1) Introduction: The role of soluble integrins in post-COVID-19 complications is unclear, especially in long-term pulmonary lesions. The purpose of this study was to investigate the association between soluble ITGa2, ITGaM and ITGb2 integrin subunits and long COVID-19 pulmonary complications. (2) Methodology: Post-COVID-19 patients were enrolled.

Preliminary studies: differences in microRNA expression in asthma and chronic obstructive pulmonary disease.

Introduction: The asthma- and chronic obstructive pulmonary disease (COPD)-related morbidity has been increasing during the recent years. Both asthma and COPD are diseases of inflammatory etiology. The increasing interest in the pathomechanisms involved in the development of obstructive pulmonary diseases seems to be fully justified.

The Role of CXC Chemokines in Pulmonary Fibrosis of Systemic Lupus Erythematosus Patients.

The inflammatory process in systemic lupus erythematosus (SLE) affects many organs including the lungs. CXC chemokines are suggested to play an important role in the pathogenesis of SLE and pulmonary fibrosis. To estimate the concentrations of CXCL9, CXCL10, CXCL11 in bronchoalveolar lavage fluid (BALF) of patients with and without pulmonary involvements of SLE to evaluate CXC chemokines role in the pathogenesis of pulmonary fibrosis in SLE.
