COPD flare-ups: Simple blood test could be a life-saver in COPD cases | Lucknow News

Lucknow: A simple blood test every three months could save the lives of Chronic Obstructive Pulmonary Disease (COPD) patients by predicting sudden flare-ups. These tests can also assess the risk of dangerous blood clots that may lead to heart attacks, strokes, or blockages in the lungs.This was revealed in a study conducted at KGMU. Published in Aug in the journal Cureus under the title “Evaluation of Prothrombotic Biomarkers in Stable and Exacerbation Phases of Chronic Obstructive Pulmonary Disease,” the research found that during flare-ups, certain blood substances rise sharply, creating a “pro-clotting” state. Doctors say this could pave the way for simple blood tests that warn of flare-ups in advance and help prevent serious complications. Prof. Kamlesh Kumar Gupta, the study’s lead author and a faculty member in the medicine department, said COPD is a long-term lung disease that affects around 5–6% of the population, often caused by years of smoking or exposure to harmful pollutants. He stressed that the disease affects the whole body, not just the lungs. The greatest risk comes during sudden flare-ups, when symptoms worsen rapidly and patients often require hospitalisation. Our study shows that these flare-ups trigger body-wide changes, making the blood stickier and more prone to clotting, he said. Explaining the findings, Prof Gupta said, “For years, we’ve treated these flare-ups primarily as a respiratory crisis. Our findings show it’s also a vascular crisis. When a patient’s breathing worsens, their risk of forming a dangerous blood clot simultaneously increases. It’s a silent threat that we can now begin to unmask.” The research compared 30 patients with stable COPD to 30 patients experiencing severe flare-ups. Blood tests showed that patients in crisis had significantly higher levels of clotting markers, especially a substance called fibrinogen. “Fibrinogen turned out to be the star player,” said Dr Shantanu Singh, the study’s corresponding author The study further confirmed fibrinogen’s importance through a test accuracy method, which gave it a score of 0.89 out of 1.0—indicating it is a highly reliable marker. Researchers believe this could transform COPD care, helping doctors predict flare-ups earlier, identify patients at greater risk of clots, and provide more personalized treatment with medications to prevent inflammation or clotting.
