The Impact

Survival outcomes of patients with end stage renal disease are worse than those of many metastatic cancers. Kidney disease patients are often inflicted with higher rates of cardiovascular disease, in which nearly half of the mortalities are attributed to adverse cardiovascular events. Of the multifarious reasons for this detrimental impact, dysbiosis in the intestinal microbiome is surfacing as a potential participant. This is likely due to the numerous metabolic and inflammatory shifts found in chronic kidney disease, as well as environmental changes within the intestinal lumen. Studies are beginning to link microbiota alterations mediated by chronic kidney disease to negative cardiovascular outcomes. Here, recent findings connecting dysbiosis in chronic kidney disease and various cardiovascular insults are reviewed. Impact statement Negative alterations, or dysbiosis, in the intestinal microbial community balance in response to chronic kidney disease is emerging as a substantial and important factor in inducing and exacerbating multiple comorbid conditions. Patients with renal insufficiency experience a substantial increase in cardiovascular risk, and recent evidence is shedding light on the close interaction between microbiome dysbiosis and increased cardiovascular events in this population. Previous association and recent causality studies utilizing experimental animal models have enriched our understanding and confirmed the impact of microbial community imbalance on cardiac health in both the general population and in patients with renal impairment.

AbstractThe effect of blood pressure (BP) on the incident cardiovascular events, progression to end-stage renal disease (ESRD) and mortality were evaluated among chronic kidney disease (CKD) patients with and without antihypertensive treatment. This nationwide study used the Korean National Health Insurance Service-Health Screening Cohort data. The hazards of outcomes were analysed according to the systolic BP (SBP) or diastolic BP (DBP) among adults (aged ≥ 40 years) with CKD and without previous cardiovascular disease or ESRD (n = 22,278). The SBP and DBP were ≥ 130 mmHg and ≥ 80 mmHg in 10,809 (48.52%) and 11,583 (51.99%) participants, respectively. During a median 6.2 years, 1271 cardiovascular events, 201 ESRD incidents, and 1061 deaths were noted. Individuals with SBP ≥ 130 mmHg and DBP ≥ 80 mmHg had higher hazards of hypertension-related adverse outcomes compared to the references (SBP 120–129 mmHg and DBP 70–79 mmHg). SBP < 100 mmHg was associated with hazards of all-cause death, and composite of ESRD and all-cause death during follow-up only among the antihypertensive medication users suggesting that the BP should be < 130/80 mmHg and the SBP should not be < 100 mmHg with antihypertensive agents to prevent the adverse outcome risk of insufficient and excessive antihypertensive treatment in CKD patients.

Chronic kidney disease (CKD) and cardiovascular disease are intimately linked. They share major risk factors, including age, hypertension, and diabetes, and common pathogenetic mechanisms. Furthermore, reduced renal function and kidney injury documented with albuminuria are independent risk factors for cardiovascular events and mortality. In major renal outcome trials and subsequent meta-analyses in patients with CKD, ACE (angiotensin-converting enzyme) inhibitors and ARBs (angiotensin II receptor blockers) were shown to effectively retard CKD progression but not to significantly reduce cardiovascular events or mortality. Thus, a high residual risk for cardiovascular disease progression under standard-of-care treatment is still present for patients with CKD. In contrast to the above, several outcome trials with SGLT-2 (sodium-glucose cotransporter-2) inhibitors and MRAs (mineralocorticoid receptor antagonists) clearly suggest that these agents, apart from nephroprotection, offer important cardioprotection in this population. This article discusses existing evidence on the effects of SGLT-2 inhibitors and MRAs on cardiovascular outcomes in patients with CKD that open new roads in cardiovascular protection of this heavily burdened population.

The Impact

Patients with chronic kidney disease (CKD) are often instructed to adhere to a renal-specific diet depending on the severity and stage of their kidney disease. The prescribed diet may limit certain nutrients, such as phosphorus and potassium, or encourage the consumption of others, such as high biological value (HBV) proteins. Eggs are an inexpensive, easily available and high-quality source of protein, as well as a rich source of leucine, an essential amino acid that plays a role in muscle protein synthesis. However, egg yolk is a concentrated source of both phosphorus and the trimethylamine N-oxide precursor, choline, both of which may have potentially harmful effects in CKD. The yolk is also an abundant source of cholesterol which has been extensively studied for its effects on lipoprotein cholesterol and the risk of cardiovascular disease. Efforts to reduce dietary cholesterol to manage dyslipidemia in dialysis patients (already following a renal diet) have not been shown to offer additional benefit. There is a paucity of data regarding the impact of egg consumption on lipid profiles of CKD patients. Additionally, egg consumption has not been associated with the risk of developing CKD based on epidemiological studies. The egg yolk also contains bioactive compounds, including lutein, zeaxanthin, and vitamin D, which may confer health benefits in CKD patients. Here we review research on egg intake and CKD, discuss both potential contraindications and favorable effects of egg consumption, and describe the need for further research examining egg intake and outcomes in the CKD and end-stage renal disease population.

Abstract Background We explored whether clinically relevant baseline characteristics of patients with type 2 diabetes can modify the effect of glucagon-like peptide-1 receptor agonists (GLP-1 RA) or sodium-glucose cotransporter-2 inhibitors (SGLT-2i) on the risk of major adverse cardiovascular events (MACE). Methods We investigated Medline and EMBASE through June 2019. We included randomized clinical trials reporting the effect of GLP-1 RA or SGLT-2i on MACE in subgroups of patients with type 2 diabetes, identified through key baseline factors: established cardiovascular disease; heart failure; chronic kidney disease; uncontrolled diabetes; duration of diabetes; hypertension; obesity; age; gender and race. Hazard ratios (HRs) and 95% confidence intervals (CIs) from trials were meta-analyzed using random-effects models. Results Ten trials enrolling 89,790 patients were included in the analyses. Subgroup meta-analyses showed a 14% risk reduction of MACE in patients with established cardiovascular disease [GLP1-RA: HR, 0.86 (95% CI, 0.80–0.93); SGLT-2i: 0.86 (0.80–0.93)], and no effect in at-risk patients without history of cardiovascular events [GLP1-RA: 0.94 (0.82–1.07); SGLT-2i: 1.00 (0.87–1.16)]. We observed a trend toward larger treatment benefits with SGLT-2i among patients with chronic kidney disease [0.82 (0.69–0.97)], and patients with uncontrolled diabetes for both GLP1-RA or SGLT-2i [GLP1-RA: 0.82 (0.71–0.95); SGLT-2i: 0.84 (0.75–0.95)]. Uncontrolled hypertension, obesity, gender, age and race did not appear to modify the effect of these drugs. Conclusions In this exploratory analysis, history of cardiovascular disease appeared to modify the treatment effect of SGLT2i or GLP1-RA on MACE. Chronic kidney disease and uncontrolled diabetes should be further investigated as potential effect modifiers.

IntroductionPatients with chronic kidney disease (CKD) are at heightened cardiovascular risk, which has been associated with abnormalities of bone and mineral metabolism. A deeper understanding of these abnormalities should facilitate improved treatment strategies and patient-level outcomes, but at present there are few large, randomised controlled clinical trials to guide management. Positive associations between serum phosphate and fibroblast growth factor 23 (FGF-23) and cardiovascular morbidity and mortality in both the general and CKD populations have resulted in clinical guidelines suggesting that serum phosphate be targeted towards the normal range, although few randomised and placebo-controlled studies have addressed clinical outcomes using interventions to improve phosphate control. Early preventive measures to reduce the development and progression of vascular calcification, left ventricular hypertrophy and arterial stiffness are crucial in patients with CKD.Methods and analysisWe outline the rationale and protocol for an international, multicentre, randomised parallel-group trial assessing the impact of the non-calcium-based phosphate binder, lanthanum carbonate, compared with placebo on surrogate markers of cardiovascular disease in a predialysis CKD population—the IMpact of Phosphate Reduction On Vascular End-points (IMPROVE)-CKD study. The primary objective of the IMPROVE-CKD study is to determine if the use of lanthanum carbonate reduces the burden of cardiovascular disease in patients with CKD stages 3b and 4 when compared with placebo. The primary end-point of the study is change in arterial compliance measured by pulse wave velocity over a 96-week period. Secondary outcomes include change in aortic calcification and biochemical parameters of serum phosphate, parathyroid hormone and FGF-23 levels.Ethics and disseminationEthical approval for the IMPROVE-CKD trial was obtained by each local Institutional Ethics Committee for all 17 participating sites in Australia, New Zealand and Malaysia prior to study commencement. Results of this clinical trial will be published in peer-reviewed journals and presented at conferences.Trial registration numberACTRN12610000650099.

Background. The magnitude of the problem of chronic kidney disease (CKD) is enormous, and the prevalence keeps rising. To highlight the burden of CKD in developing countries, the authors looked at end-stage renal disease (ESRD) patients seen at the University of Nigeria Teaching Hospital (UNTH), Enugu, South-East Nigeria.Method. ESRD patients seen from 01/05/1990 to 31/12/2003 were recruited. Records from A&E Department, medical-out-patients, wards and dialysis unit were used.Results. A total of 1001 male versus 537 female patients were reviewed. About 593 male versus 315 female patients had haemodialysis. The mean age was years and 86.5% were <60 years. Primary renal disease could not be determined in 51.6% while hypertension and glomerulonephritis accounted for −17.2% and 14.6%, respectively. Death from renal causes constituted 22.03% of medical deaths.Conclusion. The prognosis for CKD patients in Nigeria is abysmal. Only few patients had renal-replacement-therapy (RRT). The prohibitive cost precludes many patients. This underscores the need for preventive measures to reduce the impact of CKD in the society.
