Cognitive impairment and health outcomes in non-dialysis chronic kidney disease: a systematic review and meta-analysis.

Background: Cognitive impairment is prevalent in individuals with chronic kidney disease (CKD), but its effects on health outcomes remain unclear. While cognitive impairment can affect self-management, its role in CKD has been insufficiently explored. This systematic review aimed to examine the association between cognitive impairment and health outcomes or self-management ability among persons with CKD.

Biomarkers of Kidney Failure and All-Cause Mortality in CKD.

Background: Chronic kidney disease (CKD) carries a variable risk for multiple adverse outcomes, highlighting the need for a personalised approach. This study evaluated several novel biomarkers linked to key disease mechanisms to predict the risk of kidney failure (first event of eGFR <15 ml/min/1.73m2 or kidney replacement therapy), all-cause mortality, and a composite of both.

Development, Rasch analysis and validation of the kidney symptom burden questionnaire (KSB-Q).

Background: Increasingly, patient-reported outcome measures (PROMs) are used to monitor chronic kidney disease (CKD) symptoms in routine clinical practice. However, such symptom measurement currently requires completion of multiple, often lengthy, PROMs, which may lead to questionnaire fatigue, lower levels of completion, and missing data. Moreover, many CKD-specific PROMs lack evidence of important measurement properties and few were developed using contemporary psychometric methods.

Diagnosis and management of monoclonal gammopathy of renal significance: A British Society for Haematology good practice paper.

This guideline provides consensus opinion on the investigations required for people presenting with suspected monoclonal gammopathy of renal significance to both nephrology and haematology physicians. The guideline discusses the principles of treating a patient with MGRS and provides recommendations for both supportive management and haematological therapy. It details the recommended on-going monitoring required for both specialty areas.

Interplay between periodontitis and chronic kidney disease.

Periodontitis is a ubiquitous chronic inflammatory disease affecting the supporting tissues of the teeth and is a major cause of multiple tooth loss. Despite being preventable, periodontitis and dental caries are responsible for more years lost to disability than any other human condition. The most severe form of periodontitis affects 1 billion individuals, and its prevalence is increasing globally.

Accuracy of glomerular filtration rate estimation using creatinine and cystatin C for identifying and monitoring moderate chronic kidney disease: the eGFR-C study.

Background: Estimation of glomerular filtration rate using equations based on creatinine is widely used to manage chronic kidney disease. In the UK, the Chronic Kidney Disease Epidemiology Collaboration creatinine equation is recommended. Other published equations using cystatin C, an alternative marker of kidney function, have not gained widespread clinical acceptance.

The fibroblast hormone Endotrophin is a biomarker of mortality in chronic diseases.

Fibrosis, driven by fibroblast activities, is an important contributor to morbidity and mortality in most chronic diseases. Endotrophin, a signaling molecule derived from processing of type VI collagen by highly activated fibroblasts, is involved in fibrotic tissue remodeling. Circulating levels of endotrophin have been associated with an increased risk of mortality in multiple chronic diseases.

Evaluation of the stopping angiotensin converting enzyme inhibitor compared to angiotensin receptor blocker (STOP ACEi trial) in advanced and progressive chronic kidney disease.

In the STOP-ACEi trial, the outcome was similar whether or not renin-angiotensin system inhibitors (RASi) were discontinued. We now investigate whether the effect of withdrawing angiotensin converting enzyme inhibitors (ACEi) or angiotensin-receptor blockers (ARBs) differed. In this open label trial patients with estimated glomerular filtration rates (eGFR) under 30ml/min per 1.

Global use of electronic patient-reported outcome systems in nephrology: a mixed methods study.

Objectives: The use of electronic patient-reported outcome (ePRO) systems to support the management of patients with chronic kidney disease is increasing. This mixed-methods study aimed to comprehensively identify existing and developing ePRO systems, used in nephrology settings globally, ascertaining key characteristics and factors for successful implementation.

Study Design: ePRO systems and developers were identified through a scoping review of the literature and contact with field experts.

Associations with age and glomerular filtration rate in a referred population with chronic kidney disease: methods and baseline data from a UK multicentre cohort study (NURTuRE-CKD).

Background: Chronic kidney disease (CKD) is common but heterogenous and is associated with multiple adverse outcomes. The National Unified Renal Translational Research Enterprise (NURTuRE)-CKD cohort was established to investigate risk factors for clinically important outcomes in persons with CKD referred to secondary care.

Methods: Eligible participants with CKD stages G3-4 or stages G1-2 plus albuminuria >30 mg/mmol were enrolled from 16 nephrology centres in England, Scotland and Wales from 2017 to 2019.

Removal of ethnicity adjustment for creatinine-based estimated glomerular filtration rate equations.

Creatinine-based estimated glomerular filtration rate equations (eGFRcreatinine) are used to measure excretory kidney function in clinical practice. Despite inter and intra-patient variability, eGFRcreatinine has excellent clinical utility and provides the basis for the classification system for chronic kidney disease (CKD), for kidney function monitoring, treatment interventions and referral pathways. The 4-variable modification of diet in renal disease (MDRD) eGFRcreatinine equation was introduced in 2000 and recommended by the National Institute for Health and Care Excellence (NICE) in 2008.

Mesenchymal stromal cell therapy compared to SGLT2-inhibitors and usual care in treating diabetic kidney disease: A cost-effectiveness analysis.

Background And Objectives: To simulate the cost-effectiveness of Mesenchymal Stromal Cell (MSC) therapy compared to sodium/glucose co-transporter 2 inhibitors (SGLT2i) or usual care (UC) in treating patients with Diabetic Kidney Disease (DKD).

Design, Setting, Participants, And Measurements: This Markov-chain Monte Carlo model adopted a societal perspective and simulated 10,000 patients with DKD eligible for MSC therapy alongside UC using a lifetime horizon. This cohort was compared with an SGLT2i alongside UC arm and a UC only arm.

Renin-Angiotensin System Inhibition in Advanced Chronic Kidney Disease.

Background: Renin-angiotensin system (RAS) inhibitors - including angiotensin-converting-enzyme (ACE) inhibitors and angiotensin-receptor blockers (ARBs) - slow the progression of mild or moderate chronic kidney disease. However, the results of some studies have suggested that the discontinuation of RAS inhibitors in patients with advanced chronic kidney disease may increase the estimated glomerular filtration rate (eGFR) or slow its decline.

Methods: In this multicenter, open-label trial, we randomly assigned patients with advanced and progressive chronic kidney disease (eGFR, <30 ml per minute per 1.

Electronic patient-reported outcomes in chronic kidney disease.

Considerable research and investment have focused on the use of electronic patient-reported outcomes (ePROs) in nephrology. However, systematic collection of ePROs to inform the care of patients with chronic kidney disease remains sporadic. A change in culture is needed to encourage their wider adoption in clinical practice.
