Drug dosing in accordance with the renal function is a long-standing challenge to clinicians. For many years it has been evident that in many clinical situations there is no easy way to correctly dose any drug that is mainly cleared by the kidneys. Despite the development of many formulas for estimating the glomerular filtration rate, they all have serious shortcomings. Much effort has been put in to develop estimation formulas to evaluate the renal function as an alternative to direct methods with the aim of safely dosing drugs that are mainly cleared by the kidneys...

INTRODUCTION: Cisplatin also known as Cis-Diammine-Dichloroplatinum (CDDP) is a chemotherapeutic alkylating nephrotoxic agent. Thus, it is necessary to know if renal function is normal before starting chemotherapy. Glomerular Filtration Rate (GFR) can be assessed directly by using a radiopharmaceutical (dGFR). Estimated GFR (eGFR) method use, Serum Creatinine (SCR) levels in mathematical formulae such as Cockroft-Gault (CG) and abbreviated. Modified Diet in Renal Disease (aMDRD). The serum creatinine level is a function of GFR but is relatively insensitive for detecting early renal insufficiency...

Hepatocellular carcinoma is an antecedent of liver illnesses, including viral hepatitis, alcohol abuse, or metabolic disease. Transforming growth factor-Beta (TGF-b) plays an important role in creating a favorable microenvironment for tumor cell growth via two major mechanisms: an intrinsic activity as an autocrine growth factor and an extrinsic activity by inducing microenvironment changes. Recently stem cell therapy as also been a promising and potential treatment for liver cancer and in addition signaling pathways like GF/GFR systems, SDF-1α/CXC4 ligand receptor interaction and PI3K/Akt signaling, and cytokines has been identified to regulate cell fate decisions, and can be utilized to positively influence cell therapy outcomes...

AIMS: Cystatin C have shown to be a renal function parameter with higher sensitivity and specificity than serum creatinine. In tubular diseases, cystatin C degradation and an increase in its urinary elimination would be observed. We have tried to define if different kinds of kidney diseases may significantly affect the serum levels of cystatin C. DESIGN AND METHODS: Four hundred and four patients were studied: 249 men and 155 women, mean age was 64.3±10.1 years...

PURPOSE: Asians have some of the highest rates of end-stage renal disease, but there is limited information on the risk factors for chronic kidney disease (CKD) in the Asian general population. A risk score for incident CKD for the general population has been developed from the US Framingham Heart Study (FHS) Offspring cohort. This score has been validated on Caucasians and African-Americans, but has not been tested on Asians. We aimed to assess the importance of the FHS risk factors and the performance of the FHS risk score in predicting incident CKD at 10 years in a Thai community-based population...

BACKGROUND: Accurately determining renal function is essential for clinical management of HIV patients. Classically, it has been evaluated by estimating glomerular filtration rate (eGFR) with the MDRD-equation, but today there is evidence that the new Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation has greater diagnostic accuracy. To date, however, little information exists on patients with HIV-infection. This study aimed to evaluate eGFR by CKD-EPI vs. MDRD equations and to stratify renal function according to KDIGO guidelines...

AIMS: To investigate whether blockade of calcium channels (CCs) or Angiotensin II Type 1 receptors 1 (AT1R) modulates renal responses to nitric oxide synthesis inhibition (NOSI) in humans. METHODS: Fourteen sodium replete healthy volunteers underwent 90 minute infusions of 3.0 μg.kg.min-1 NG-nitro-L-arginine methylester (L-NAME), on 3 occasions, preceded by 3 days of either placebo (PL), 10 mg Manidipine (MANI), or 50 mg losartan (LOS). At each phase, mean arterial pressure (MAP), glomerular filtration rate (GFR, inulin), renal blood flow (RBF, p-aminohippurate), urinary sodium (UNaV) and 8-isoprostane (U8-iso-PGF2αV - an oxidative stress marker) were measured...

A recent study showed that a significant fall in mean arterial pressure (MAP) occurred following intravenous injection of two novel superparamagnetic iron oxide nanoparticles (SPION), MF66 and OD15. To assess if this was caused by excessive glomerular clearance, the effect of both particles on renal function was studied. Experiments were performed on sodium pentobarbital anaesthetised male Wistar rats (250 - 350 g). Twenty min urine clearances were taken, followed by an i.v. bolus of MF66, OD15 (2 mg/kg) or dH2O (0...
