The introduction of the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines has substantially contributed to the early detection of different stages of chronic kidney disease (CKD). Several recent studies from different parts of the world mention a CKD prevalence of between 8 and 13%. There are several reasons the CKD prevalence found in a study of a particular population is clearly overestimated. The structure of the population pyramid (young or older age) of the study sample may result in high or low CKD prevalence...

Both the incidence and prevalence of chronic kidney disease are increasing in the elderly population. Although aging is known to induce kidney injury, the underlying molecular mechanisms remain unclear. Sirtuin 1 (Sirt1), a longevity gene, is known to protect kidney cell injury from various cellular stresses. In previous studies, we showed that the podocyte-specific loss of Sirt1 aggravates diabetic kidney injury. However, the role of Sirt1 in aging-induced podocyte injury is not known. Therefore, in this study we sought to determine the effects of podocyte-specific reduction of Sirt1 in age-induced kidney injury...

The gradual loss of weight and function of muscle in patients with chronic kidney disease as in the elderly impacts the quality of life. Early management should help slow the functional limitation. Physical activity is the first therapy to propose that ensures stability of muscle mass and improved function. Resistance training programs have proven effective but are not yet widely available in nephrology units. The nutritional management should not be forgotten because there is a resistance to anabolism and protein intake should be involved in physical activity program...

WHAT IS KNOWN AND OBJECTIVES: Cinacalcet may reduce cardiovascular disease (CVD) mortality in elderly patients with chronic kidney disease (CKD). However, previous studies of the clinical responses to cinacalcet have exhibited discrepancies due to highly variable baseline levels of parathyroid hormone (PTH), kidney function and age. Little is known about the true effect of cinacalcet on stage 5 CKD. The objective of the current observational study was to evaluate whether cinacalcet-mediated lowering of PTH levels improves all-cause mortality and cardiovascular disease mortality in younger stage 5 CKD patients (mean age <55 years)...

BACKGROUND: Depression is prevalent in patients with chronic kidney disease (CKD) and continues to increase in elderly adults. Therefore, the aim of our study was to examine the relationship between CKD and depression in older patients. METHODS: We conducted a cross-sectional study based on 2013 Korea National Health and Nutrition Examination Survey data. In total, data of 973 subjects aged ≥65 years were analyzed, and the estimated glomerular filtration rate (eGFR) was calculated using the Chronic Kidney Disease Epidemiology Collaboration equation...

 As a major chronic non-communicable disease, hypertension is the most important risk factor for cardiovascular disease, chronic kidney disease, stroke and, if not treated appropriately, premature death. A population-based approach aimed at decreasing high blood pressure among the general population is an important component of any comprehensive plan to prevent hypertension. However, few studies have investigated generational differences in knowledge about, and consciousness of, hypertension. Thus, we conducted a questionnaire survey about hypertension, with the aim of clarifying differences of understanding about hypertension between high school students and elderly people...

Hypertension (HT) is the most important risk factor for cardiovascular diseases. Over the past 25 years, the number of individuals with hypertension and the estimated associated deaths has increased substantially. There have been great debates in the past few years on the blood pressure (BP) targets. The 2013 European Society of Hypertension and European Society of Cardiology HT guidelines suggested a unified systolic BP target of 140 mmHg for both high-risk and low-risk patients. The 2014 Joint National Committee report further raised the systolic BP targets to 150 mmHg for those aged ≥ 60 years, including patients with stroke or coronary heart disease, and raised the systolic BP target to 140 mmHg for diabetes...

BACKGROUND: The benefit of early dialysis initiation remains controversial with a paucity of data in Asians. Therefore, we undertook this study to investigate the association between timing of initiation of dialysis and mortality in Singapore. METHODS: The study used data from the Singapore Renal Registry database on 3286 patients with incident end-stage renal disease (ESRD) who commenced maintenance dialysis between January 2008 and December 2011. The data was further linked with the National Death Registry to acquire survival information until December 2013...

BACKGROUND: Studies in chronic kidney disease populations suggest that the non-glomerular filtration rate (GFR) determinants of serum levels of the low-molecular-weight protein filtration markers cystatin C, β2-microglobulin (B2M), and beta-trace protein (BTP) are less affected by age, sex, and ethnicity than those of creatinine. STUDY DESIGN: Cross-sectional study. SETTING & PARTICIPANTS: Predominantly elderly participants selected from the Age, Gene/Environment Susceptibility Kidney Study (AGES-Kidney; N=683; mean [SD] age, 79 [4] years; GFR, 62 [17]mL/min/1...

AIM: To investigate the clinical features of heart failure in extremely elderly patients. METHODS: We analyzed 1163 consecutive hospitalized heart failure patients. The patients were divided into an extremely elderly group (≥85 years-of-age, n = 88) and a non-extremely elderly group (<85 years-of-age, n = 1075). RESULTS: The extremely elderly group had higher rates of hypertension, chronic kidney disease, anemia, higher systolic blood pressure and lower body mass index, and lower use of β-blockers and anticoagulants compared with the non-extremely elderly group...

Chronic kidney disease has been linked to cognitive impairment and morphological brain change. However, less is known about the impact of kidney functions on cerebral cortical thickness. This study investigated the relationship between kidney functions and global or lobar cerebral cortical thickness (CTh) in 259 non-demented elderly persons. Forty-three participants (16.7%) had kidney dysfunction, which was defined as either a glomerular filtration rate (GFR) of <60 ml/min/1.73 m(2) or presence of proteinuria...

BACKGROUND: Dialysis in older adults with chronic kidney disease (CKD) and comorbidities may not be associated with improved life expectancy compared to conservative management. To inform clinical practice, we performed a systematic review of all available studies examining this hypothesis. METHODS: We performed a systematic review of retrospective and prospective cohort studies of older adults with stage-5 CKD who chose dialysis (hemodialysis or peritoneal dialysis) or opted for conservative management (including management of complications of CKD and palliative care)...

PURPOSE: Overt hypothyroidism has adverse clinical consequences and might worsen prognosis in critically ill elderly patients. However, the difficult interpretation of thyroid function tests (TFT) due to non-thyroidal illness (NTI) has led to discouragement of screening for thyroid dysfunction. Our aim was to determine the prevalence of TFT compatible with hypothyroidism and to study its influence on mortality among hospitalized elderly patients. METHODS: In this prospective study we consecutively included all patients ≥60 years admitted by the Internal Medicine Department to the hospital ward (n = 451) of the Cesar Milstein Hospital in Buenos Aires, Argentina...

Global burden disease studies point out that one of the top cause-specific anemias is iron deficiency (ID). Recent advances in knowledge of iron homeostasis have shown that fragile patients are a new target population in which the correction of ID might impact their morbidity, mortality and quality of life. We did a systematic review using specific search strategy, carried out the review of PubMed database, Cochrane Database of systemic reviews and international guidelines on diagnosis and clinical management of ID from 2010 to 2016...

BACKGROUND: Few studies have examined the relationships between the prevalence of chronic kidney disease (CKD) and the metabolic risk factors in a developing country such as China, where genetic and environmental backgrounds differ from those in Western countries. METHODS: The subjects of this cross-sectional study were the individuals from 18 to 92y. The metabolic syndrome (MetS) was defined based on the criteria of Adult Treatment Panel Third Report (ATP III), but using body mass index (BMI) instead of waist circumference...

Recent studies suggest that trimethylamine N-oxide (TMAO) is associated with the development of chronic kidney disease and heart failure. In this study, we investigated the importance of organic cation transporters (OCTs) in the clearance and tissue distribution of TMAO. The low affinity and high capacity transport of TMAO by mouse and human OCT1 and OCT2 was observed. Uptake and efflux of TMAO by the mouse hepatocytes as well as TMAO uptake into mouse kidney slices were significantly decreased by the addition of tetraethylammonium or Oct1/2 double knockout (dKO)...

Chronic kidney disease and hyperuricemia have been associated to an increased risk and a worse prognosis in acute ischemic stroke. Several mechanisms, including platelet dysfunction, coagulation disorders, endothelial dysfunction, inflammation, and an increased risk of atrial fibrillation could be implicated. The role of serum uric acid in this setting is still object of debate. We enrolled all the consecutive patients admitted to our department for acute ischemic stroke. Cox regression analysis was used to evaluate the risk of in-hospital death considering serum uric acid levels and all the comorbidities...

SUMMARY: Colonoscopy is a useful tool in modern medicine and is increasingly employed for both diagnostic and treatment reasons. However, its effectiveness is highly reliant on the quality of bowel cleansing. Among different bowel-cleansing agents available, PEG (polyethylene glycol) is considered to be the safest cleansing agent, especially in relation to fluid and electrolyte problems. We present here a case of severe symptomatic hyponatremia that developed after the use of PEG for an elective colonoscopy...

Dabigatran etexilate (DE) is a direct thrombin inhibitor, which has been approved for the treatment of non-valvular atrial fibrillation (AF), and for the prevention and treatment of venous thromboembolism (VTE). Despite large randomized clinical trials and independent observational studies providing robust data concerning DE safety and efficacy, some physicians still perceive mild-to-moderate renal impairment and old age as a relative contraindication to its use. In this article, we review the available scientific evidence supporting the use of DE in these clinical situations...
