Serum creatinine is commonly used as a marker of renal function, but increases in serum creatininemight not represent changes in glomerular filtration rate (GFR). INCB039110 (2-(3-(4-(7H-pyrrolo[2,3-day]pyrimidin4-yl)-1H-pyrazol-1-yl)-1-(1-(3-fluoro-2-(trifluoromethyl)isonicotinoyl) piperidin-4-yl)azetidin-3-yl)acetonitrile) is an inhibitor of the Janus kinases (JAKs) with selectivity for JAK1....

Recently, neutrophil gelatinase-associated lipocalin (NGAL) has been introduced as a sensitive and early marker of acute kidney injury [5] . NGAL in cirrhosis and chronic renal failure has not been investigated so far. We have therefore analyzed NGAL and GFR in patients with Dear Sir, Renal dysfunction is a frequent and clinically relevant problem in patients with cirrhosis of the liver [1] . W...

BACKGROUND Serum cystatin C, a cysteine protease inhibitor, has been suggested as a new marker of glomerular filtration rate (GFR). This study explored the possibility of replacing the creatinine clearance (CrCl) estimation of GFR with cystatin C in early detection of renal impairment in cancer patients on chemotherapy. METHODS Serum creatinine and cystatin C concentrations as well as 24-h Cr...

BACKGROUND Cystatin C (CysC) is an alternative marker to creatinine for estimation of the glomerular filtration rate (GFR). Hormones such as thyroid hormones and glucocorticoids are known to have an impact on CysC. In this study, we examined the effect of growth hormone (GH) on CysC in patients with acromegaly undergoing transsphenoidal surgery. METHODS Creatinine, CysC, GH and insulin-like g...

INTRODUCTION Micro-albuminuria is considered an early marker of glomerular injury in patients with diabetes but it has yet to be determined whether testing for markers of tubular injury can also identify people who are at risk of progressive renal disease. OBJECTIVE To evaluate markers of tubular injury and renal characteristics in a sample of community treated type 2 diabetic subjects. MAT...

Urine formation in the eel, acclimated to freshwater (FW) and seawater (SW) was studied. SW eels maintained higher plasma and urine osmotic and ionic concentrations than FW eels. Polyethylene-1,2-glycol-14C (PEG-14C) clearance was 29% greater than methoxy-inulin-3H clearance. PEG-14C clearance was considered to be the glomerular filtration rate (GFR). The GFR of SW and FW eels did not differ. U...

Fibroblast growth factor23 (FGF23), an early marker of kidney dysfunction, is associated with cardiovascular death. Its role in HIV-positive individuals is unknown. We measured FGF23 in 100 HIV-negative and 191 HIV-positive nondiabetic adults with normal baseline estimated glomerular filtration rate (GFR). We measured GFR by iohexol annually, albumin-creatinine ratio (ACR) every 6 months, as we...

There is no simple method to measure glomerular filtration rate (GFR) in swine, an 15 established model to study renal disease. We developed a protocol to measure GFR in conscious 16 swine with the plasma clearance of iohexol. We used two groups: testing and validation, of 8 17 animals each. Ten milliliters of iohexol (6.47 g) were injected by the marginal auricular vein and 18 blood samples (3...

OBJECTIVE Renal dysfunction is associated with increased cardiovascular morbidity and mortality. The alteration in renal function as a marker of mortality in pulmonary thromboembolism (PTE) has not been studied extensively. METHODS Four hundred four consecutive patients diagnosed with non-high-risk PTE (without cardiogenic shock or blood pressure <90 mm Hg) were prospectively enrolled in the ...

Serum creatinine level is the most commonly used indices for assessment of glomerular filtration rate (GFR), even though these indices have been shown to have some limitations in clinical practice. We investigated the diagnostic efficacy of serum cystatin C compared to that of serum creatinine levels and identified the relating factors associated with changes in serum cystatin C levels in gout ...
