Which body protein serves as an equivalent marker for inflammation and may indicate future mortality risk in patients?

Serum albumin is a protein synthesized by the liver that plays a crucial role in maintaining oncotic pressure and transporting various substances in the blood. It is often used as a biomarker for nutritional status and inflammation. In the context of inflammation, serum albumin levels can decrease due to the acute phase response, where the body prioritizes the production of other proteins (like C-reactive protein) that are involved in the inflammatory process. Low levels of serum albumin have been associated with an increased risk of morbidity and mortality in various patient populations, particularly in those with chronic diseases, such as kidney disease or heart failure.

This relationship between serum albumin and both inflammation and mortality risk underscores its significance as a clinical marker. It reflects not only the nutritional state of the individual but also offers insights into underlying pathological processes, including chronic inflammation. Elevated inflammatory states often result in serum albumin being lost from the bloodstream or not produced sufficiently, thus indicating that alterations in serum albumin levels can provide essential information regarding a patient's health and prognosis.
