Manifestly Different

With the first wave of the COVID-19 pandemic behind us in the UK, attention is turning to how healthcare systems will cope with COVID-19 during flu season. Infection with SARS-CoV-2, the virus that causes COVID-19, or influenza viruses can both lead to pneumonia and lesions in the lungs. But are there any differences in the damage caused? Researchers now investigate by comparing lung CT scans (pictured) of patients with pneumonia who tested positive for SARS-CoV-2 (left) or influenza (right). Artificial intelligence-based software analysed the lesions (red) detected. Lesions in COVID-19 pneumonia were more often found in peripheral regions of the lung and close to the membranes lining the lungs, the pleura when compared to lesions in influenza pneumonia. Conversely, influenza pneumonia more often showed the airways filling with mucus and fluid accumulating between the pleura. These differences aren't significant enough to aid diagnosis but this approach can help identify lesions and evaluate treatment.

Pleural fluid is a liquid secreted by the mesothelial cells that form the pleural membranes lining the pleural cavity. These membranes form a sac and the lungs are enveloped by it (not inside it). Imagine the sac as an inflated balloon and the lungs as your fist pushing into the membrane of the balloon. Your fist becomes covered in balloon skin but is not physically inside the balloon.

Normal pleural fluid should be clear and contains some mesothelial cells and white blood cells. A volume of about 10mls is spread thinly over the pleural membranes to form a lubricating surface that also aids in the mechanics of breathing. Trauma, pneumonia or cancer however can result in a significant build up of blood or fluid in the pleural cavity which can cause the lungs to collapse. This is called a pleural effusion. By draining the fluid the pressure on the lungs can be released making breathing easier. The fluid can then be examined in a microscope for blood, and abnormal numbers/morphology of cells (e.g presence of malignant mesothelial cells or increased number and type of white blood cells) that can help with a diagnosis.
