Cross-sectional studies represent the second line of evidence (after case reports) in the ladder of evidence aimed at defining disease aetiology. This study design is used to generate hypotheses about the determinants of a given disease but also to investigate the accuracy of diagnostic tests and to assess the burden of a given disease in a population. The intrinsic limitation of cross-sectional studies, when applied to generate aetiological hypotheses, is that both the exposure under investigation and the disease of interest are measured at the same point in time...

SYNOPSIS Over the last two decades, experts have reported a rising number of deaths caused by chronic kidney disease (CKD) along the Pacific coast of Central America, from southern Mexico to Costa Rica. However, this specific disease is not associated with traditional causes of CKD, such as aging, diabetes, or hypertension. Rather, this disease is a chronic interstitial nephritis termed chronic kidney disease of nontraditional etiology (CKDnT). According to the Pan American Health Organization (PAHO) mortality database, there are elevated rates of deaths related to kidney disease in many of these countries, with the highest rates being reported in El Salvador and Nicaragua...

INTRODUCTION: The Revised Cardiac Risk Index (RCRI) is a popular classification system to estimate patients' risk of postoperative cardiac complications based on preoperative risk factors. Renal impairment, defined as serum creatinine >2.0 mg/dL (177 µmol/L), is a component of the RCRI. The estimated glomerular filtration rate has become accepted as a more accurate indicator of renal function. We will externally validate the RCRI in a modern cohort of patients undergoing non-cardiac surgery and update its renal component...

BACKGROUND: Chronic kidney disease (CKD) is an independent risk factor for cardiovascular disease (CVD). However, the association between CKD and CVD risk in patients with type 2 diabetes mellitus (T2DM) in China has not yet been well investigated. This study aimed to determine the association of CKD with the risks of coronary heart disease (CHD) and stroke in a Chinese population with T2DM. METHODS: A total of 1401 inpatients with T2DM at the Second Affiliated Hospital of Zhejiang University School of Medicine between April 2008 and November 2013 were included in this study...

BACKGROUND: There is an increasing recognition of epidemics of primarily tubular-interstitial chronic kidney disease (CKD) clustering in agricultural communities in low- and middle-income countries (LMICs). Although it is currently unclear whether there is a unified underlying aetiology, these conditions have been collectively termed CKD of undetermined cause (CKDu). CKDu is estimated to have led to the premature deaths of tens to hundreds of thousands of young men and women over the last 2 decades...

As the global burden of chronic kidney disease continues to increase, so does the need for a cost-effective renal replacement therapy. In many countries, patient outcomes with peritoneal dialysis are comparable to or better than those with haemodialysis, and peritoneal dialysis is also more cost-effective. These benefits have not, however, always led to increased utilization of peritoneal dialysis. Use of this therapy is increasing in some countries, including China, the USA and Thailand, but has proportionally decreased in parts of Europe and in Japan...

Experts have questioned the clinical relevance of early stage 3 chronic kidney disease, particularly in elderly individuals and in those without albuminuria. A recent study published in PLoS Medicine provides further evidence that many older adults with stage 3a chronic kidney disease will never worsen, whereas some may even improve. Despite limited generalizability, the results support the current, more nuanced classification of chronic kidney disease for use in clinical practice and in future epidemiologic research...

Limited data are available on epidemiology and drug use in Chinese hypertensive patients with chronic kidney disease (CKD). We determined the prevalence; awareness, treatment, and control rates of hypertension; anti-hypertensive use, expenditure pattern; and factors associated with hypertension prevalence and control in Chinese patients with CKD. This was one of the largest cross-sectional surveys that enrolled 6079 CKD participants (mean age, 51.0 ± 16.37 years) with or without hypertension from 22 centres across China...

Kidney diseases in human immunodeficiency virus (HIV)-infected patients are often misdiagnosed. Despite reductions in morbidity and mortality owing to widespread use of highly effective combination antiretroviral therapy (cART), acute kidney injury (AKI) and chronic kidney disease (CKD) are still more common in these patients than in the general population, and are associated with poor health outcomes. HIV-associated nephropathy and HIV immune complex kidney diseases are the more recognizable HIV-related kidney diseases...

PURPOSE: Kidney filtration decreases with age, which results in an increased frequency of chronic kidney disease (CKD) in the elderly population. The purpose of the study was to assess the prevalence and epidemiology of CKD in the Polish elderly population. METHODS: A representative sample of the Polish elderly population, composed of 918 people (F 452, M 466) in the age of ≥75 years, was chosen. All participants had their history, anthropometric measures and biochemical parameters (creatinine, fasting glucose, complete cholesterol) evaluated...

PURPOSE OF REVIEW: Recent studies indicate that acute kidney injury (AKI) and chronic kidney disease (CKD) are interconnected syndromes. Although the majority of patients who suffer an episode of AKI will recover laboratory indices suggesting complete or near complete recovery of renal function, a significant portion of post-AKI survivors will develop major kidney events, including development of late-stage CKD, need for renal replacement therapies, and death. RECENT FINDINGS: Our review highlights epidemiology of adverse post-AKI events, association of AKI with late development of nonrenal adverse outcomes, use of bedside equations that facilitate prognostication of adverse renal outcomes of AKI, and how variability in serum creatinine values in individual patients, even among those with normal baseline renal function may indicate risk for the development of CKD...

BACKGROUND: Depression is common in individuals with chronic kidney disease (CKD). However, data on the association of albuminuria, which together with reduced estimated glomerular filtration rate (eGFR) defines CKD, with depression are scarce and conflicting. In addition, it is not clear when in the course from normal kidney function to CKD the association with depression appears. METHODS: We examined the cross-sectional associations of albuminuria and eGFR with depressive symptoms and depressive episodes in 2872 and 3083 40- to 75-year-old individuals, respectively, who completed the baseline survey of an ongoing population-based cohort study conducted in the southern part of The Netherlands between November 2010 and September 2013...

Chronic kidney disease (CKD) affects 8-16% of adults worldwide and is associated with multiple adverse outcomes. It includes a heterogeneous group of conditions with widely varied associated risks; risk stratification is therefore vital for clinical management. Use of the CKD Epidemiology Collaboration (CKD-EPI) equation to estimate glomerular filtration rate (GFR) instead of the Modification of Diet in Renal Disease (MDRD) equation will reduce, though not eliminate, over-diagnosis of CKD. Cystatin C is recommended as an alternative measure of GFR but is not yet widely used...

BACKGROUND AND OBJECTIVES: (51)Cr EDTA clearance (CL) from plasma is used to estimate glomerular filtration rate (GFR). We propose that current methods for analysing the raw (51)Cr EDTA measurements over-simplifies the disposition of (51)Cr EDTA and therefore could produce biased GFR estimates. The aim of this study was to develop a population pharmacokinetic model for (51)Cr EDTA disposition and to compare model-predicted GFR to other methods of estimating renal function. PATIENTS AND METHODS: Data from 40 individuals who received ~7...

Chronic kidney disease (CKD) is currently defined by abnormalities of kidney structure or function assessed using a matrix of variables - including glomerular filtration rate (GFR), thresholds of albuminuria and duration of injury - and is considered by many to be a common disorder globally. However, estimates of CKD prevalence vary widely, both within and between countries. The reasons for these variations are manifold, and include true regional differences in CKD prevalence, vagaries of using estimated GFR (eGFR) for identifying CKD, issues relating to the use of set GFR thresholds to define CKD in elderly populations, and concerns regarding the use of one-off testing for assessment of eGFR or albuminuria to define the prevalence of CKD in large-scale epidemiological studies...

BACKGROUND AND OBJECTIVES: For many women pregnancy is the first contact with health services, thus providing an opportunity to identify renal disease. This study compares causes and long-term renal outcomes of biopsy-proven renal disease identified during pregnancy or within 1 year postpartum, with nonpregnant women. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Native renal biopsies (1997-2012), in women of childbearing age (16 to <50 years), from 21 hospitals were studied...

BACKGROUND: Evidence has suggested that protein from dairy may be less detrimental to renal health than protein from nondairy products. However, to our knowledge, no previous studies have used cystatin C-based measures of the estimated glomerular filtration rate (eGFR). OBJECTIVE: We investigated the associations of sources of protein and dairy with the change in the eGFR in persons with a normal or mildly decreased eGFR. DESIGN: We included 3798 participants, aged 26-65 y, from the Doetinchem Cohort study who were examined ≥3 times 5 y apart...

INTRODUCTION: The 2013 Kidney Disease Outcomes Quality Initiative Clinical Practice Guideline suggests measuring cystatin C (sCys) in adults with glomerular filtration rate (GFR) based on creatinine (sCr) between 45 and 59 mL/min/1.73 m(2) if confirmation of chronic kidney disease (CKD) is required. There is not enough evidence to recommend the use of sCys or sCr to estimate GFR in kidney transplant recipients. OBJECTIVES: Our aims were to describe the evolution of sCr, sCys, and GFR in a group of kidney transplant patients and to determine their association with some markers of morbidity at 1 year...
