Haematological Consequences of Systemic Inflammation: A Critical Narrative Review of Pathophysiology, Clinical Manifestations, Biomarkers and Therapeutic Implications

Zaccheaus Awortu Jeremiah & Joyce Ezekiel Etura · International Blood Research & Reviews · 2026

Inflammation is inseparable from blood-cell biology: circulating cells detect inflammatory cues, bone-marrow progenitors alter lineage output, erythroid iron supply is actively restricted, and haemostatic pathways can be recruited as components of host defence. Yet the expression...
