Clinical value of urinary retinol-binding protein in ascites due to cirrhosis.

ABSTRACT: The aim of the present study was to explore the clinical value of urinary retinol-binding protein (RBP) level in the prognosis of cirrhotic ascites by assessment of the RBP levels prior to and following ascites treatment. The levels of urinary RBP, urinary microalbumin (mAlb), serum urea nitrogen (urea) and serum creatinine (Cr), and the estimated glomerular filtration rate (eGFR) were measured in 90 patients with cirrhosis and ascites hospitalized in a single institution between May 2011 and January 2012, and in 30 healthy controls. The levels of urinary mAlb, serum urea and serum Cr were higher in the cirrhotic patients compared with the healthy controls (P<0.05). Urinary RBP levels were significantly higher and eGFR was significantly lower in the liver cirrhosis group compared with the healthy control group (P<0.01). Urinary RBP, urinary mAlb, serum urea and serum Cr increased and eGFR decreased as the severity of the ascites increased (P<0.05). Urinary RBP was significantly higher in patients whose ascites did not respond or was refractory compared with those in whom it subsided (P<0.05), exhibiting a gradual increase over time in the former and a gradual reduction over time in the latter group (P<0.05). Increased urinary RBP and decreased eGFR in the early stage of cirrhosis ascites suggested impaired renal function, which serves a role in the process of ascites formation. These results indicated that urinary RBP is a sensitive indicator of early renal injury in patients with ascites due to cirrhosis and is closely associated with the progression of cirrhotic ascites.

Project description:BackgroundDespite its significant association with limb loss and death, peripheral artery disease (PAD) remains underdiagnosed and undertreated. The current accepted gold-standard for PAD screening, the ankle brachial index (ABI), is limited by operator dependence, erroneous interpretation, and unreliability in patients with diabetes. Fatty acid binding protein 3 (FABP3) is an intracellular protein that becomes released into circulation and excreted into urine following skeletal muscle injury. We examined the prognostic ability of urinary FABP3 (uFABP3) in predicting adverse PAD-related events.MethodsIn this prospective case-control study, urine samples were collected from patients with PAD (n = 142) and without PAD (n = 72). The cohort was followed for 2 years. uFABP3 was normalized to urinary creatinine (uCr) (uFABP3/uCr). The primary outcome was major adverse limb event (MALE; composite of vascular intervention [open or endovascular] or major limb amputation). The secondary outcome was worsening PAD status (drop in ABI≥0.15). Cox regression analyses with multivariable adjustment for baseline demographic and clinical variables were performed to assess the prognostic value of uFABP3/uCr with regards to predicting MALE and worsening PAD status.ResultsPatients with PAD had significantly higher median [IQR] uFABP3/uCr levels (3.46 [2.45-6.90] vs. 2.61 [1.98-4.62], p = 0.001). MALE and worsening PAD status were observed in 21 (10%) and 28 (14%) patients, respectively. uFABP3/uCr predicted MALE and worsening PAD status with adjusted hazard ratios (HR) of 1.28 (1.16-1.41, p = 0.001) and 1.16 (1.02-1.27, p = 0.021), respectively. Patients with high uFABP3/uCr had a lower 2-year freedom from MALE (86 vs. 96%, p = 0.047) and worsening PAD status (78 vs. 99%, p = 0.001). There was good discriminatory ability for uFABP3/uCr in predicting the primary outcome of MALE, with an area under the receiver operating characteristics curve (AUROC) of 0.78.ConclusionsMeasuring uFABP3/uCr levels in patients with PAD can help identify those at high risk of adverse PAD-related events. This study highlights the prognostic value of uFABP3 in risk-stratifying individuals for further diagnostic vascular evaluation or aggressive medical management.
