Serum Cysteine Rich Protein 61 and Cystatin C for Early Detection of Acute Kidney Injury in Patients With Heart Diseases

February 21, 2022 updated by: Shrook S. Ahmed, Assiut University

Serum Cysteine Rich Protein 61 and Cystatin C for Early Detection of Acute Kidney Injury in Patients With Acute Coronary Syndromes

Acute Kidney Injury (AKI) is defined as an absolute increase in serum creatinine ≥0.3 mg/dl (≥26.4 μmol/l), a percentage increase in serum creatinine ≥50% (1.5-fold from baseline), or a reduction in urine output (documented oliguria < 0.5 ml/kg/hour for > 6 hours) S.creatinine which is considered the gold standard currently for diagnosis of AKI remains unchanged until 50% of kidney function falls down. It is affected by non-specific factors like diet, age, dehydration, muscle mass, gender, and drugs.

There were evidences of the association between AKI and acute coronary syndrome (ACS); First, AKI detection may be missed by cardiologists. Physicians tend to disregard mild or transient serum creatinine elevation during hospital stay for ACS, and they often attribute small serum creatinine increases to laboratory variations.

Detailed Description

Cystatin C (CysC), a cystatin protease inhibitor, is less affected by non-specific factors. When glomerular filtration rate (GFR) decreases, CysC begins to increase.

CysC was recommended to be measured in addition to creatinine in GFR estimation.

Cysteine-rich protein 61 (Cyr61) is a cysteine-rich secretory protein that promotes cell proliferation, adhesion, chemotaxis, embryonic development and neovascularization . Previous studies have detected low expression level of Cyr61 in normal adult kidney and high expression of Cyr61 in ischemic rats and mice kidney, which suggests that Cyr61 may be a potential biomarker for diagnosis of AKI . CYR61 might possibly identify patients with more severe kidney injury, which would be very beneficial for early treatment of AKI after
