, including hypertrophic cardiomyopathy, systemic sclerosis, and myelofibrosis, according to research published in .
The data indicate that “a single threshold value of absolute monocyte counts of 0.95 K/mcL could be used to identify high-risk patients with a fibrotic disease,” said Madeleine K. D. Scott, a researcher at Stanford (Calif.) University, and coauthors. The results “suggest that monocyte count should be incorporated into the clinical assessment” and may “enable more conscientious allocation of scarce resources, including lung transplantations,” they said.
While other published biomarkers – including gene panels and multicytokine signatures – may be expensive and not readily available, “absolute monocyte count is routinely measured as part of a complete blood count, an inexpensive test used in clinical practice worldwide,” the authors said.
Further study of monocytes’ mechanistic role in fibrosis ultimately could point to new treatment approaches.
