A recent study conducted by researchers at Aarhus University has shed light on a possible connection between certain medications used to treat chronic inflammatory diseases and the occurrence of unexpected blood clots. The research, published in the journal Inflammopharmacology, focuses on the role of the JAK-STAT signaling pathway, a crucial communication system within the body.
The study aimed to understand why medications, specifically JAK inhibitors, designed to alleviate symptoms of chronic inflammatory conditions, sometimes lead to this serious side effect. “In the study, we uncover the potential links between components of the JAK-STAK signaling pathway, blood markers in patients with blood clots, and the genetic factors that contribute to the risk of blood clots in patients. This helps improve our understanding of why we see an increased risk of blood clots when using JAK inhibitors,” explained Stine Rabech Haysen, the study’s first author and former medical student at the Department of Biomedicine at Aarhus University.
Utilizing publicly available data from previous studies on patients with blood clots, the researchers compared this data with a healthy control group. While no direct genetic explanation was found, the study revealed a statistically significant enrichment of genes regulated by the JAK-STAT signaling pathway among those whose expression is altered in patients experiencing blood clots.
“Although we cannot draw definitive conclusions about the mechanistic link between the use of JAK inhibitors and the risk of blood clots, our study demonstrates the potential of using data mining to identify and shed light on possible mechanisms of drug side effects,” stated Per Qvist, an associate professor at the Department of Biomedicine and one of the study’s senior authors.
The findings, while preliminary, hold potential for improving patient safety. “For the average person, our study means that we’re getting closer to understanding why some drugs can have dangerous side effects like blood clots. And going forward, our method could help identify and prevent serious side effects, potentially making drug treatment safer,” added Tue Wenzel Kragstrup, another senior author and associate professor at the Department of Biomedicine.
The researchers now plan to expand their investigation by applying their data mining method to other medications to determine its broader applicability in detecting potential side effects.
Disclaimer: It is important to note that this study suggests a possible link and does not establish a definitive causal relationship between JAK inhibitors and blood clots. Further research is necessary to fully understand the mechanisms involved. Patients currently taking JAK inhibitors should consult with their healthcare providers to discuss any concerns or questions they may have. Do not stop taking any prescribed medication without consulting a doctor. This information is for general knowledge and should not be construed as medical advice.
