The world’s rising obesity epidemic is associated with a broad spectrum of ailments including atherosclerosis and non-alcoholic fatty liver (NAFL) disease. Each condition can progress from small fatty deposits to localized tissue inflammation that is potentially dangerous. For example, in arterial vessel walls inflamed atherosclerotic plaques are prone to rupture (thrombosis) to form blood clots that may cause life-threatening strokes or heart attacks.

Now a new study sheds light on the long-term effects of highly inflamed plaques on the progression of liver fibrosis.

“In the past, research focused on particular conditions of the vasculature or liver, but the contribution of chronic systemic effects and inter-organ communication to the pathogenesis of both diseases, and notably liver disease, remained understudied,” explained corresponding author James Hamilton, Ph.D., professor of physiology and biophysics at Boston University School of Medicine (BUSM) and professor of biomedical engineering at Boston University.

The researchers found that advanced inflamed vascular plaques were associated with progressive liver disease. According to Hamilton these observations support the emerging broad view that chronic unresolved inflammation may impart systemic effects leading to secondary conditions, including diabetes, rheumatoid arthritis, colitis, cancer and Alzheimer’s disese.

“The good news of our study showing this inflammatory relationship between vascular and liver disease is that the systemic nature of these diseases also presents a valuable therapeutic approach, including the treatment with natural molecules that lower inflammation without unwanted side effects.”
