The number of nephroprotection targets attained is associated with cardiorenal outcomes and mortality in patients with diabetic kidney disease. The CKD-REIN cohort study. Diabetes Obes Metab 2024; 26:1908-1918. [PMID: 38418407 DOI: 10.1111/dom.15507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 02/01/2024] [Accepted: 02/02/2024] [Indexed: 03/01/2024]
Abstract
AIM The risk of cardiorenal events remains high among patients with diabetes and chronic kidney disease (CKD), despite the prescription of recommended treatments. We aimed to determine whether the attainment of a combination of nephroprotection targets at baseline (glycated haemoglobin <7.0%, urinary albumin-creatinine ratio <300 mg/g, blood pressure <130/80 mmHg, renin-angiotensin system inhibition) was associated with better cardiorenal outcomes and lower mortality. MATERIALS AND METHODS From the prospective French CKD-REIN cohort, we studied 1260 patients with diabetes and CKD stages 3-4 (estimated glomerular filtration rate: 15-60 ml/min/1.73 m2); 69% were men, and at inclusion, mean ± SD age: 70 ± 10 years; estimated glomerular filtration rate: 33 ± 11 ml/min/1.73 m2. The median follow-up was 4.9 years. RESULTS In adjusted Cox regression models, the attainment of two nephroprotection targets was consistently associated with a lower risk of cardiorenal events [hazard ratio 0.70 (95% confidence interval 0.57-0.85)], incident kidney failure with replacement therapy [0.58 (0.43-0.77)], four major adverse cardiovascular events (cardiovascular death, myocardial infarction, stroke, hospitalization for heart failure) [0.75 (0.57-0.99)] and all-cause mortality [0.59 (0.42-0.82)] when compared with the attainment of zero or one target. For patients with a urinary albumin-creatinine ratio ≥300 mg/g, those who attained at least two targets had lower hazard ratios for cardiorenal events [0.61 (0.39-0.96)], four major adverse cardiovascular events [0.53 (0.28-0.98)] and all-cause mortality [0.35 (0.17-0.70)] compared with those who failed to attain any targets. CONCLUSIONS These findings suggest that the attainment of a combination of nephroprotection targets is associated with better cardiorenal outcomes and a lower mortality rate in people with diabetic kidney disease.

Adherence to the Kidney Disease: Improving Global Outcomes CKD Guideline in Nephrology Practice Across Countries. Kidney Int Rep 2020; 6:437-448. [PMID: 33615069 PMCID: PMC7879121 DOI: 10.1016/j.ekir.2020.11.039] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 11/11/2020] [Accepted: 11/30/2020] [Indexed: 01/13/2023] Open
Abstract
Introduction The uptake of the Kidney Disease: Improving Global Outcomes (KDIGO) 2012 chronic kidney disease (CKD) Guideline is not fully described in real-world nephrology practice across the world. Methods We used baseline data from the CKD Outcomes and Practice Patterns Study (2013-2017), a 4-country cohort of patients with estimated glomerular filtration rate <60 ml/min per 1.73 m2 recruited from national samples of nephrology clinics, to describe adherence to measures for monitoring and delaying CKD progression. Data were collected as in clinical practice, except laboratory measures per protocol in France. Results The mean age ranged from 65 years in Brazil to 72 years in Germany. Albuminuria (mostly proteinuria) was measured routinely in 36% to 43% of patients in Brazil, Germany, and the United States. Blood pressure control (≤140/90 mm Hg) ranged from 49% in France to 76% in Brazil; <40% of patients had blood pressure ≤130/80 mm Hg everywhere but Brazil (52%). More than 40% of nephrologists in Brazil reported a systolic blood pressure target ≤130 mm Hg for nondiabetic patients without proteinuria, but only 19% to 24% elsewhere. Prescription of renin-angiotensin aldosterone system inhibitors ranged from 52% in the United States to 81% in Germany. Dietary advice was more frequent for salt than protein intake; dietitian visits were uncommon. In nondiabetic patients, achievement of all 3 targets including blood pressure ≤130/80 mm Hg, renin-angiotensin aldosterone system inhibition, and dietary advice, ranged from 10% in the United States to 32% in Brazil; in treated diabetic patients, this ranged from 6% to 11% after including hemoglobin A1c target. Conclusion Adherence to recommendations to slow CKD progression is low in typical practice settings, and substantial variation among countries for some indicates opportunities for improvement.

Abstract
BACKGROUND The aim of this paper was to examine the difference between males and females regarding association between malnutrition risk and hypoglycemia through a sub-analysis of a cross-sectional study of newly admitted patients to internal medicine departments. METHODS Malnutrition risk, assessed with Nutritional Risk Screening 2002 (NRS2002), and serum albumin were measured upon admission. Logistic regression was applied to men and women separately, to test the effect of malnutrition and hypoalbuminemia on incidence of hypoglycemia. RESULTS Included were 1186 patients (50.4% males, 39.2% with positive NRS2002). Rate of positive NRS2002 was similar across sexes (36.5% vs. 41.2% in males and females respectively, P=0.204). Among females, NRS2002 was associated with higher incidence of hypoglycemia (9.5% vs. 2.4% in NRS2002 negative females, P<0.001). Among males, no such difference was noted (9.2% compared to 7.1% in NRS2002 positive and negative males respectively, P=0.520). The weight loss/decreased food intake criterion of the NRS2002 was significantly higher in the hypoglycemic group within females (P=0.03). Logistic regression showed that serum albumin was inversely associated with hypoglycemia in both females (OR 0.477, 95% CI 0.282-0.806, P=0.006) and males (OR 0.532, 95% CI 0.355-0.795, P=0.002). However, increased malnutrition risk was associated with hypoglycemia only among females (OR 2.007, 95% CI 1.058-3.809, P=0.033). Diabetes status was associated with hypoglycemia (OR 1.907, 95% CI 1.056-3.445, P=0.032) only in males; this association did not occur in females. CONCLUSIONS Malnutrition risk, as measured by the NRS2002, is associated with significantly increased incidence of hypoglycemia in women alone. Females who lose weight prior to hospitalization have an increased risk to develop hypoglycemia.

Abstract
Age-related metabolic and renal changes predispose older people to an increased risk of diabetes mellitus and diabetic kidney disease, respectively. As the prevalence of the ageing population is increasing, because of increased life expectancy, the prevalence of older people with diabetic kidney disease is likely to increase. Diabetic kidney disease is associated with an increased risk of adverse outcomes and increased costs to healthcare systems. The management includes promotion of a healthy lifestyle and control of cardiovascular risk factors such as hyperglycaemia, hypertension and dyslipidaemia. Older people are a heterogeneous group of people from a community-living fit and independent person to a fully dependent individual residing in a care home. Therefore, management in this age group should be based on a patient's functional level adopting tight metabolic control in the fit individual and relaxed targets in the frail person. However, despite the maximum available therapy, a significant number of patients with diabetic kidney disease still progress to renal failure and experience adverse cardiac outcomes. Therefore, future research is required to explore methods of early detection of diabetic kidney disease and to investigate novel therapeutic interventions to further improve the outcomes.

Abstract
Background:
MicroRNAs (miRNAs) play an important role in the pathogenesis of
various renal diseases, including Chronic Kidney Diseases (CKD). CKD refers to the gradual loss
of kidney function with the declining Glomerular Functional Rate (GFR).
Objective:
This study focused on the regulatory mechanism of miRNA to control gene expression
in CKD.
Methods:
In this context, two lists of Differentially Expressed Genes (DEGs) were obtained; one
from the three selected experiments by setting a cutoff p-value of <0.05 (List A), and one from a
list of target genes of miRNAs (List B). Both lists were then compared to get a common dataset of
33 miRNAs, each had a set of DEGs i.e. both up-regulated and down-regulated genes (List C).
These data were subjected to functional enrichment analysis, network illustration, and gene
homology studies.
Results:
This study confirmed the active participation of various miRNAs i.e. hsa -miR-15a-5p,
hsa-miR-195-5p, hsa-miR-365-3p, hsa-miR-30a-5p, hsa-miR-124-3p, hsa-miR-200b-3p, and hsamiR-
429 in the dysregulation of genes involved in kidney development and function. Integrated
analyses depicted that miRNAs modulated renal development, homeostasis, various metabolic
processes, immune responses, and ion transport activities. Furthermore, homology studies of
miRNA-mRNA hybrid highlighted the effect of partial complementary binding pattern on the
regulation of genes by miRNA.
Conclusion:
The study highlighted the great values of miRNAs as biomarkers in kidney diseases.
In addition, the need for further investigations on miRNA-based studies is also commended in the
development of diagnostic, prognostic, and therapeutic tools for renal diseases.

Abstract
In our aging population, kidney disease management needs to take into account the frailty of the elderly. Standardized geriatric assessments can be proposed to help clinicians apprehend this dimension in their daily practice. These tools allow to better identify frail patients and offer them more personalized and harmless treatments. This article aims to focus on the kidney diseases commonly observed in elderly patients and analyze their specific nephrogeriatric care modalities. It should be noticed that all known kidney diseases can be also observed in the elderly, most often with a quite similar clinical presentation. This review is thus focused on the diseases most frequently and most specifically observed in elderly patients (except for monoclonal gammopathy associated nephropathies, out of the scope of this work), as well as the peculiarities of old age nephrological care.
