Randomized, controlled trials that compared any antihypertensive agent with placebo or another agent in hypertensive or normotensive patients with diabetes and normoalbuminuria (albumin excretion rate <30 mg/d) were identified on Medline, in Embase, on the Cochrane Controlled Trials Register, in

However, the setting of research priorities is usually performed by clinicians, academics, and funders, with little involvement of patients or caregivers and using processes that lack transparency. A national workshop was convened in Australia to generate and prioritize research questions in chronic kidney disease (CKD) among diverse stakeholder groups. Patients with CKD (n=23), nephrologists/surgeons (n=16), nurses (n=8), caregivers (n=7), and allied health professionals and researchers (n=4) generated and voted on intervention questions across 4 treatment categories: CKD stages 1 to 5 (non-dialysis dependent), peritoneal dialysis, hemodialysis, and kidney transplantation. The 5 highest ranking questions (in descending order) were as follows: How effective are lifestyle programs for preventing deteriorating kidney function in early CKD? What strategies will improve family consent for deceased donor kidney donation, taking different cultural groups into account? What interventions can improve long-term post-transplant outcomes? What are effective interventions for post hemodialysis fatigue? How can we improve and individualize drug therapy to control post-transplant side effects? Priority questions were focused on prevention, lifestyle, quality of life, and long-term impact. These prioritized research questions can inform funding agencies, patient/consumer organizations, policy makers, and researchers in developing a CKD research agenda that is relevant to key stakeholders.

Qualitative research methods are used to elicit in-depth and detailed insights into people's attitudes, beliefs, emotions and experiences-much of which may remain unspoken during clinical encounters. Questions about patients' beliefs and preferences for treatment can be addressed by qualitative research and inform evidence-based strategies for delivering patient-centred care. Systematic reviews of multiple primary qualitative studies bring together findings from different studies to offer new and more comprehensive understandings of social phenomena across various healthcare contexts and populations and are an emerging methodology in the literature including for care in chronic kidney disease. This article will provide a framework for the systematic review of qualitative research so readers can make sense of these study types an...

These outcomes are well described, but patient perspectives and experiences of living with ADPKD are under-recognized. MEDLINE, Embase, PsycINFO and CINAHL were searched to August 2014. Studies were analyzed using thematic synthesis. From 21 studies (n = 247), we derived five themes: unvalidated pain (medical trivialization, inadequacy of pain management); persisting uncertainties and ambiguities (lacking diagnostic clarity, disempowerment in self-care, unpredictable daily disruptions, inability to plan ahead, financial discrimination); genetic guilt and resentment (blaming parents, self-blame, constant burden of guilt); precariousness in pursuing parenthood (prognostic uncertainty, owning the decision, needing directive co...

We aimed to estimate the proportion of LRs that could potentially have been detected earlier because of increases in patients' general hospital activity. A cohort of patients starting dialysis in the English NHS (National Health Service) during 2010/11 was approximated using hospital administrative data. The time between first recorded contact with a consultant nephrologist and starting dialysis was used to categorize the timeliness of referral. Monthly rates of inpatient activity prior to starting dialysis for both referral types were compared with the national average. A cohort of 3928 patients was detected. One-third (34%) of the cohort started dialysis <90 days after their first referral to a nephrologist. Rates were higher for patients starting haemodialysis than peritoneal dialysis. The proportion of pat...

Since 1997, the Cochrane Renal Group has produced over 100 systematic reviews that have collectively had an important impact on nephrology care, guidelines and policy. In this article, we reflect on the ongoing need for randomized trials and systematic reviews in contemporary nephrology and the achievements of the Cochrane Collaboration so far. We also describe some of the challenges in clinical research still faced by the nephrology community today.

The nephrologist also has the important task of delaying the start of dialysis for as long as possible. Delaying dialysis slightly, even just one year for each patient, will have ethical, social and economic advantages that should be duly weighed and carefully evaluated when adopting organizational models of care involving nephrology. The nephrologist bases his work on the clinical competence acquired and maintained through appropriate training programs based on CME courses and, above all, daily clinical practice that, in order to be truly educational, must reach a sufficient volume of activity to guarantee the best possible outcome to the patient.

A well-conducted systematic review can adequately inform not only the clinicians, but also the policy makers and researchers about the benefits and risks of a particular intervention. In this article, we describe how to critically appraise the methods and interpret the results of a systematic review of interventional trials and apply the findings of a systematic review to the clinical questions.

Several factors characterize the increase in the risk of developing renal damage in diabetic patients, distinguished in diabetes-related factors, genetic factors and other factors. Diagnosis requires standard annual urinalysis and dipstick for albumin. In patients with negative urine dipstick, the routine approach is to evaluate the albumin/creatinine ratio (ACR) in the first voided urine. The degree of renal impairment is assessed by an annual evaluation of the glomerular filtration rate (GFR) by the Cockroft/Gault formula in normoalbuminuric patients. In patients with overt nephropathy this evaluation needs to be more frequent. A thorough therapeutic approach, in both the early and later stages of diabetic nephropathy, is fundamental because of the increased risk of morbidity and mortality. Renal damage (and the natural history of the disease) is approached on three different levels. Primary...

Proteinuria is an independent marker of renal and cardiovascular (CV) disease in hypertensive populations, particularly in high-risk groups such as diabetic patients. Effective blood pressure (BP) control and proteinuria management are associated with significant improvements in the risk of key adverse outcomes, although a causative relationship needs careful assessment. Available antihypertensives have varying effects on proteinuria reduction. Drugs affecting the renin system offer antiproteinuric and renoprotective effects that are probably at least partially independent of their BP effects. Economic evaluations of these interventions confirm their cost-saving benefits relative to other antihypertensives, but outcomes-based research is needed in some settings.

We sought to summarize prognosis following kidney allograft failure and identify potentially beneficial interventions or modifiable risk factors. We searched MEDLINE and EMBASE (inception to 1 October 2013) and article reference lists without language restriction and selected cohort studies of all-cause mortality and fatal infection-related and cardiovascular events in people starting dialysis following kidney allograft failure. Two reviewers independently extracted data on study design, participant characteristics, dialysis modality, transplant nephrectomy, immunosuppression strategy, transplant-naive comparators and risk of bias. Discrepancies were resolved with a third reviewer. Forty studies comprising 249 716 participants met the inclusion criteria. The first year of dialysis therapy was associated with the highest mortality. By random effects meta-analysis, annual risk...
