The purpose of this study was to determine the number of prescribed antibiotics being appropriately adjusted and to assess antibiotics with the highest incorrect dosing based on the patient’s renal function according to distinguished guidelines. The study was conducted at a 446-bed university hospital. One hundred and fifty patients admitted through different wards of the hospital were included...

BACKGROUND Guidelines recommend the modification of diet in the renal disease (MDRD) formula or the Cockcroft-Gault formula for estimating the glomerular filtration rate (GFR). However, there is an ongoing discussion whether the MDRD formula should be used in the general population as several studies have found a large underestimation of its GFR estimates. METHODS In this study, 1,029 low-ris...

BACKGROUND The performance of the Cockcroft-Gault (CG) equation, the Modification of Diet in Renal Disease (MDRD) formula, and the Chronic Kidney Disease Epidemiology Collaboration equation (CKD-EPI) was evaluated in body mass index (BMI) categories. MATERIAL AND METHODS In this retrospective cohort study in diabetic patients, creatinine clearance was measured by collecting 24-hour urines. Re...

BACKGROUND Agreement between spot and 24-hour urine protein measurements is poor in kidney transplant recipients. We investigated whether using formulae to estimate creatinine excretion rate (eCER), rather than assuming a standard creatinine excretion rate, would improve the estimation of proteinuria from spot urine samples in kidney transplant recipients. METHODS We measured 24 hour urine pr...

OBJECTIVE-Assessment and follow-up of early renal dysfunction is important in diabetic nephropathy. Plasma creatinine is insensitive for a glomerular filtration rate (GFR) >50 ml/min and creatinine clearance is unwieldy and subject to collection inaccuracies. We aimed to assess the reproducibility, reliability, and accuracy of plasma cystatin C as a measure of GFR ranging from normal to moderat...

OBJECTIVE Pneumoperitoneum during laparoscopy results in transient oliguria and decreased glomerular filtration and renal blood flow. The presence of oliguria and elevated serum creatinine is suggestive of acute renal injury. Serum cystatin C has been described as a new marker for the detection of this type of injury. In this study, our aim was to compare the glomerular filtration rate estimate...

BACKGROUND & AIMS There is a close relationship between chronic hepatitis B virus infection and chronic renal disease. We analyzed changes in renal function using different markers of glomerular filtration rate (GFR) in multiple studies of telbivudine treatment of patients with chronic hepatitis B virus infection. METHODS We used serum creatinine-based equations (ie, Cockcroft-Gault, Modifica...

BACKGROUND Numerous studies have assessed the accuracy of equations estimating glomerular filtration rate (eGFR) from serum creatinine in individuals with chronic kidney disease (CKD) in cross-sectional studies. Limited literature exists, however, on the consistency of performance of these equations in longitudinal studies as renal function declines. METHODS Radionucleotide-measured GFR from ...

Measurement of GFR is considered the standard for estimating renal function. However, standardized accurate GFR methodology is expensive and cumbersome; therefore, estimates of GFR based on serum creatinine concentration have been employed. The purpose of the study presented here was to assess the accuracy and precision of using serum creatinine measurements to estimate GFR in the screen cohort...

BACKGROUND Serum creatinine concentration is widely used as an index of renal function, but this concentration is affected by factors other than glomerular filtration rate (GFR). OBJECTIVE To develop an equation to predict GFR from serum creatinine concentration and other factors. DESIGN Cross-sectional study of GFR, creatinine clearance, serum creatinine concentration, and demographic and ...
