Relationship between interleukin-6 (IL-6) levels and chest X-ray severity scoring in COVID-19 patients.

The severity of coronavirus disease 2019 (COVID-19) may be measured by interleukin-6 (IL-6) and chest X-rays. Brixia score of the chest radiographs is usually used to monitor COVID-19 patients' lung problems. The aim of this study was to demonstrate the relationship between IL-6 levels and chest radiographs (Brixia score) that represent COVID-19 severity.

The Levels of Vitamin D, Metalloproteinase-9 and Tissue Inhibitor Metalloproteinase-1 in COPD Patients, Healthy Smokers and Non-Smokers of Indonesian Citizens.

Background: Exposure to cigarette smoke may stimulate the inflammatory response and activate polymorphonuclear leukocytes, thus resulting in secretion of cellular proteases. Vitamin D has the potential to modulate the inflammatory response to harmful particles in patients with Chronic Obstructive Pulmonary Disease (COPD).

Aim: This study aimed to determine the levels of vitamin D, MMP-9, and TIMP-1 in COPD subjects, healthy smokers and nonsmokers of Indonesian citizens.
