INTRODUCTION: Radical nephrectomy (RN), a recommended treatment option for patients with Renal cell carcinoma (RCC) leads to an inevitable decline in global renal function. Pathological changes in the non-tumour parenchyma of the kidney may help predict the function of the remaining kidney. MATERIALS AND METHODS: Aim of this prospective, observational study was to find histopathological factors in the non-tumor renal parenchyma that could predict the decline in global renal function postoperatively and its association with co-morbidities like diabetes (DM)...

BACKGROUND: Chronic kidney disease (CKD) is a major cause of morbidity and mortality in Sub-Saharan Africa (SSA). The majority of studies on CKD in SSA have been conducted among HIV-infected populations and mainly from large health facilities. We determined the prevalence of CKD and its predictors among populations in communities in central Uganda. METHODS: A cross-sectional study was conducted in Wakiso district using multi-stage sampling. Data was collected on age, sex, socio-economic status, history of alcohol intake, diabetes mellitus, hypertension and smoking...

BACKGROUND: Depending on hyphothalamic, hyphophyseal, and gonadal axis dysfunction, anovulatory irregular cycles occur and the probability of pregnancy decreases in the patients with chronic kidney disease (CKD). Maternal mortality and morbidity rates are increased in CKD patients; the risk of premature delivery is 70% and the risk of preeclampsia is 40% more than normal among those with a creatine level of >2.5 mg/dL. METHODS: If a pregnancy is expected in the sequel of kidney transplantation (KT), a multidisciplinary team approach should be adopted and both the gynecologist and the nephrologist should follow the patient simultaneously...

OBJECTIVES: Kinetic glomerular filtration rate estimation may have more power and versatility than the Modification of Diet in Renal Disease or Cockcroft-Gault formula for evaluating kidney function when plasma creatinine fluctuates rapidly. After kidney donation, glomerular filtration rate rapidly fluctuates in otherwise healthy patients. We compared 3 formulas for estimating glomerular filtration rate: kinetic, Modification of Diet in Renal Disease, and Cockcroft-Gault, for determining stages of acute kidney injury early after kidney donation...

BACKGROUND: In aging populations with an ever-growing burden of risk factors such as obesity, diabetes, and hypertension, chronic kidney disease (CKD) is on the rise. However, little is known about its exact prevalence among elderly adults, and often albuminuria is not included in the definition of CKD. Moreover, novel equations for the estimated glomerular filtration rate (eGFR) have recently emerged, which have not been applied comprehensively to older adults. Data on CKD awareness among the elderly are sparse...

REVIEW
Gianni B Scappaticci, Randolph E Regal
The Cockcroft-Gault (CG) equation has become perhaps the most popular practical approach for estimating renal function among health care professionals. Despite its widespread use, clinicians often overlook not only the limitations of the original serum creatinine (SCr) based equation, but also may not appreciate the validity of the many variations used to compensate for these limitations. For cirrhotic patients in particular, the underlying pathophysiology of the disease contributes to a falsely low SCr, thereby overestimating renal function with use of the CG equation in this population...

Introduction. Antibiotic treatment regimens against Pseudomonas aeruginosa lung infection in cystic fibrosis (CF) patients often include aminoglycoside antibiotics that may cause chronic renal failure after repeated courses. Aminoaciduria is an early marker of acute aminoglycoside-induced renal tubular dysfunction. We hypothesized that urinary amino acid reabsorption is decreased after repeated once-daily tobramycin therapies. Methods. In this prospective cross-sectional study creatinine clearance was estimated by the Schwartz and the Cockcroft-Gault formula...

OBJECTIVES: Decreased renal function is associated with increased cardiovascular risk. Our study was planned to verify the association of decreased renal function and subclinical coronary atherosclerosis in postmenopausal women. METHODS: We performed a retrospective review of 251 Korean postmenopausal women who visited the health promotion center for a routine health checkup. Estimated glomerular filtration rate (eGFR) was used to show renal function, which was estimated by calculated using the Cockcroft-Gault (CG) and the modification of diet in renal disease (MDRD) formulas...

When treating critically ill patients with gentamicin for severe infection, peak concentrations (Cmax) determine clinical efficacy and trough concentrations (Cmin) determine toxicity. Despite administration of body weight-standardised starting doses, a wide range of Cmax is generally observed. Furthermore, in therapeutic drug monitoring, several measures of renal function are used to predict appropriate Cmin and gentamicin dosing intervals, but the most accurate predictor is not known. This study aimed to quantify the impact of several patient parameters on gentamicin Cmax values and to determine which measure of renal function best predicts gentamicin clearance (CL)...

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 protein and albumin and spot albumin:creatinine (ACR) and spot protein:creatinine (PCR) in 181 Kidney transplant recipients...

The mean age at diagnosis of chronic lymphocytic leukemia (CLL) is 72 years, with 22.8% of patients being older than 80 years. However, the elderly are underrepresented in clinical studies of CLL. We performed a retrospective study of CLL patients aged 80 years or older at the initiation of first-line therapy in hospitals affiliated with the French intergroup on CLL (French Innovative Leukemia Organization) between 2003 and 2013. Here, we describe the clinical and biological characteristics, treatment, and outcomes for 201 patients...

PURPOSE: Vancomycin (VCM) is used in the treatment of methicillin-resistant Staphylococcus aureus infection. The dosage of VCM must be adjusted by using therapeutic drug monitoring because of the drug's narrow therapeutic concentration window. Although optimal administration based on population pharmacokinetic (PPK) analysis and/or a Bayesian method has improved prediction accuracy, serum concentrations of VCM in patients with sepsis often deviate significantly from predicted values. We investigated factors influencing prediction errors with PPK analysis in VCM dosing...

BACKGROUND: Renal impairment is a major risk factor for mortality in various populations. Three formulas are frequently used to assess both glomerular filtration rate (eGFR) or creatinine clearance (CrCl) and mortality prediction: body surface area adjusted-Cockcroft-Gault (CG-BSA), Modification of Diet in Renal Disease Study (MDRD4), and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. The CKD-EPI is the most accurate eGFR estimator as compared to a "gold-standard"; however, which of the latter is the best formula to assess prognosis remains to be clarified...
