(1) Background: The purpose of this article was to investigate the association between self-reported physical activity (PA) and all-cause mortality in ambulatory patients with chronic kidney disease (CKD), stage 4–5 including maintenance dialysis. (2) Methods: Ambulatory patients with CKD (eGFR < 30 mL/min/1.73 m2) with conservative treatment or chronic dialysis were included. PA was assessed using the Saltin–Grimby Physical Activity Level Scale. A Cox proportional hazards regression model––adjusted for age, sex, plasma–albumin, body mass index, socioeconomic status, and treatment––was applied. (3) Results: Participants (n = 374) were followed 39 ± 15 months from entry to death or censoring. Throughout the study period of 39 months, 156 deaths (42%) were registered. Regarding physical activity, 128 (34%) of the participants were inactive, 212 (57%) were moderately active, and 34 (9%) were highly or vigorously active. Moderate PA was associated with a decreased mortality risk in women (n = 150) compared to inactivity (HR 0.27 (0.15; 0.51), p < 0.001), whereas a high/vigorous level of PA was not significantly associated with mortality risk compared to inactivity. In men (n = 224), the associations between PA levels and mortality risk were not significant. (4) Conclusions: Moderate PA was associated with reduced all-cause mortality in ambulatory women with stage 4–5 CKD with or without maintenance dialysis treatment. Physical activity was not significantly associated with mortality in men.

Background: Chronic kidney disease (CKD) patients have a higher cardiovascular (CV) disease and mortality risk, elevated triglycerides (TG), and decreased high density lipoproteins (HDL). Post-hoc analysis of trials examining use of fibrate (Fib) or niacin (Nia) therapy in lowering CV outcome risk have failed to show benefit in mild to moderate kidney disease. These analyses were criticized for their study design or small sample size. We sought to examine if Fib or Nia use is associated with lower mortality risk in US veterans across CKD stages. Methods: In a retrospective cohort analysis, we identified male veterans who initiated Fib or Nia, with a high TG ≥150 mg/dL or low HDL ≤40 mg/dL between 2004-2014, and matched them on CKD stage and TG and HDL levels to unexposed men. We examined the association of Fib or Nia use (ref: unexposed) with 12-month all-cause mortality risk across CKD stage strata using an adjusted Cox proportional hazards model. Propensity scores (PS) included baseline demographics, comorbidities and lab measures and high-dimensional propensity scores (HDPS) included over 100 covariates for each drug and stage analysis. PS and HDPS analyses included score adjustment and matching. Results: The cohort had a mean±SD age of 64±12 years, and 30% had CKD stage 3A and higher. There were 69,295 Fib, 87,727 Nia, and 114,411 unexposed patients, respectively. Patient characteristics were similar across drug groups within each CKD stage. With covariate adjustment, both Fib and Nia were associated with a lower death risk compared to unexposed men in lower CKD stages (Figure A and B). Among those with CKD stage 4/5, Fib and Nia were associated with a higher death risk (HR[95%CI]: 1.43[1.15, 1.78] and 1.17[0.97,1.40], respectively). Those on Fib or Nia and in end-stage renal disease had a null association with mortality. Associations were similar for each CKD stage in PS and HDPS analyses, yet Fib and Nia were no longer associated with a lower death risk for CKD stage 3A and 3B patients. Conclusion: Mortality associations of Fib and Nia among male veterans with high TG and low HDL varied across CKD stage, where CKD stage 4/5 patients had a higher mortality risk, even in PS and HDPS analyses. While covariate balance was met, further studies are needed to examine the mechanisms for this higher observed risk in late-stage CKD patients.

Background and aims Oral health could potentially be a modifiable risk factor for adverse outcomes in chronic kidney disease (CKD) patients transitioning from predialysis treatment to maintenance dialysis and transplantation. We aimed to study the association between an index of radiographically assessed oral health, Panoramic Tomographic Index (PTI), and cardiovascular and all-cause mortality, major adverse cardiovascular events (MACEs) and episodes of bacteremia and laboratory measurements during a three-year prospective follow-up in CKD stage 4–5 patients not on maintenance dialysis at baseline. Methods Altogether 190 CKD stage 4–5 patients without maintenance dialysis attended panoramic dental radiographs in the beginning of the study. The patients were followed up for three years or until death. MACEs and episodes of bacteremia were recorded during follow-up. Laboratory sampling for C-reactive protein and leukocytes was repeated tri-monthly. Results PTI was not associated with baseline laboratory parameters or C-reactive protein or leukocytes examined as repeated measures through the 3-year follow-up. During follow-up, 22 patients had at least one episode of bacteremia, but only 2 of the bacteremias were considered to be of oral origin. PTI was not associated with incident bacteremia during follow-up. Thirty-six patients died during follow-up including 17 patients due to cardiovascular causes. During follow-up 42 patients were observed with a MACE. PTI was independently associated with all-cause (HR 1.074 95% CI 1.029–1.122, p = 0.001) and cardiovascular (HR 1.105, 95% CI 1.057–1.157, p<0.0001) mortality, as well as, incident MACEs (HR 1.071 95% CI 1.031–1.113, p = 0.0004) in the multivariable Cox models adjusted for age and kidney transplantation or CKD treatment modality during follow-up. Conclusions Radiographically assessed dental health is independently associated with all-cause and cardiovascular mortality and MACEs but not with the incidence of bacteremia in CKD stage 4–5 patients transitioning to maintenance dialysis and renal transplantation during follow-up.

Abstract Background and Aims Frailty is a complex health state of increased vulnerability to stressors and is common in those with chronic kidney disease (CKD). Frailty is strongly associated with progressive renal impairment and independently linked with adverse outcomes in all stages of CKD such as disability, falls, hospitalisation, and mortality. How frailty varies across the disease trajectory is not well-defined, particularly in those with early stages of disease. Identifying those with CKD who may be at risk of becoming frail could inform the early intervention and understanding how frailty changes across the disease spectrum may aid better future management of these patients. Method This is a secondary analysis of data of n=4736 CKD patients (42% female, mean age 59.7 (SD: 16.3) years) from a prospective observational study of physical activity behaviours. A modified assessment of frailty (based on the Fried phenotype model) was conducted across each of the CKD stages ((n=262 CKD stage 1/2, n=678 CKD stage 3, n=610 CKD stage 4/5, n=1094 haemodialysis (HD), n=177 peritoneal dialysis (PD), n=1915 transplant (TX)). Markers of frailty were defined as (1) poor endurance (defined as a VO2 peak of &lt;20ml/kg/min estimated from the Duke Activity Index Scale); (2) low physical activity level (classified as ‘insufficiently active’ using General Practice Physical Activity Questionnaire); and (3) slowness (self-reported slow walking pace (less than 3mph)). Participants were classified as ‘frail’ if ≥2 markers were present. Frequency analysis and chi-squared tests were conducted to identify and compare patients with ≥2 markers of frailty across the disease trajectory. Binominal logistical regression was performed to determine which factors were associated with being frail. Results Across the total cohort, the majority (56%) of patients exhibited ≥2 markers of frailty. The presence of frailty increased concurrently with disease decline (39% CKD stage 1/2, 58% CKD stage 3, 74% CKD stage 4/5, 76% HD, 66% PD, 39% TX). The prevalence of frailty was significantly higher in patients in CKD stage 3, CKD stage 4/5, HD and PD patients when compared to CKD stage 1/2 and TX patients (p&lt;.001). Frailty was significantly higher in patients in CKD stage 4/5 and on HD compared to those in CKD stage 3 (p&lt;.001). Patients who were female (OR = 1.42 [1.23 to 1.65] p&lt;.001), older (OR= 1.05 [1.05 to 1.06] p &lt;.001), and of non-white ethnicity (OR = 2.41 [2.00 to 2.90] p&lt;.001) had an increased likelihood of being frail. Increased number of comorbidities (OR = 1.26 [1.18 to 1.34] p&lt;.001) were associated with an increased likelihood of being frail (Figure 1). Conclusion The proportion of patients with ≥2 markers of frailty increased with disease progression until it reached a peak in HD with almost 8 out of 10 HD patients exhibiting frailty. Frailty prevalence was reduced in those with a renal TX. Over half of those in CKD stage 3 and three-quarters with CKD stage 4/5 had ≥2 markers of frailty present. Worryingly, markers of frailty were present early in the disease process with over 1/3 of patients with CKD stage 1/2 classified as frail by this modified phenotype model. Age, sex, ethnicity, and number of comorbidities were associated with the likelihood of being frail. It is important that healthcare providers actively attempt to identify patients at risk of frailty to ensure appropriate interventions addressing risk factors that may exacerbate the progression of frailty can be implemented.

Abstract Background and Aims Vascular calcification (VC) plays a major role in cardiovascular disease (CVD), which is one of the main causes of mortality in patients with chronic kidney disease (CKD). The study aims at early detection of breast arterial calcification (BAC) in different stages of CKD (stage 2, 3& 4) patients as an indicator of systemic VC. Method A case control study was conducted targeting CKD women, aged 18- 60 years old. The sample was divided into 3 groups; A,B,C (representing stage 2, 3 & 4 of CKD) from women who attended nephrology and Internal medicine clinics and admitted in inpatient ward in Suez Canal University Hospital. A 4th group (D) was formed as a control group and included women with normal kidney functions (each group (A, B, C, D) include 22 women). The selected participants were subjected to history taking, mammogram to detect BAC and biochemical assessment of lipid profile, Serum creatinine (Cr), Mg, P, Ca, PTH and FGF23. Results Our study detected presence of BAC in about 81.8% of hypertensive stage 4 CKD patients compared with 50% in stage 3 CKD, also in the majority of stage 4 CKD patients who had abnormal lipid profile parameters and electrolyte disturbance. Most of the variables had statistical significance regarding the presence of BAC. Conclusion Although it is difficult to determine the definite stage at which the risk of VC begins but in our study, it began late in stage 2 CKD, gradually increased prevalence through stage 3 and became significantly higher in stage 4. These results suggest that preventive strategies may need to begin as early as stage 2 CKD.

Background: Many drugs should be avoided or require dose-adjustment in chronic kidney disease (CKD). Previous estimates of potentially inappropriate prescribing rates have been based on data on a limited number of drugs and mainly in secondary care settings. Aim: To determine the prevalence of contraindicated and potentially inappropriate primary care prescribing in a complete population of people with CKD. Method: Cross-sectional study of prescribing patterns in a complete geographical population of people with CKD defined using laboratory data. Drugs were organised by British National Formulary advice. Contraindicated (CI) drugs: “avoid”. Potentially high risk (PHR) drugs: “avoid if possible”. Dose inappropriate (DI) drugs: dose exceeded recommended maximums. Results: 28,489 people with CKD were included in analysis, of whom 70.0% had CKD 3a, 22.4% CKD 3b, 5.9% CKD 4, and 1.5% CKD 5. 3.9% (95%CI 3.7-4.1) of people with CKD stages 3a-5 were prescribed one or more CI drug, 24.3% (95%CI 23.8-24.8) PHR drug, and 15.2% (95% CI 14.8-15.62) DI drug. CI drugs differed in prevalence by CKD stage, and were most commonly prescribed in CKD stage 4 with a prevalence of 36.0% (95%CI 33.7–38.2). PHR drugs were commonly prescribed in all CKD stages ranging from 19.4% (95%CI 17.6-21.3) in stage 4 to 25.1% (95%CI 24.5–25.7) in stage 3b. DI drugs were most commonly prescribed in stage 4, 26.4% (95%CI 24.3-28.6). Conclusion: Potentially inappropriate prescribing is common at all stages of CKD. Development and evaluation of interventions to improve prescribing safety in this high-risk populations are needed.

Abstract Background Anemia is a severe complication of chronic kidney disease (CKD) that is seen in more than 80% of patients with impaired renal function. Although there are many mechanisms involved in the pathogenesis of anemia of renal disease, the primary cause is the inadequate production of erythropoietin by the damaged kidneys. Aim of the work to assess hepcidin level in non dialysis patients (CKD stage 4 &5) treated from Hepatitis C virus and its relation to iron parameters. Patients and Methods This study was conducted on 20 CKD patients (stage 4 and 5) treated from hepatitis C virus. All candidates included in this study subjected to careful history taking, full clinical examination and investigations (including complete blood count, renal chemistry, HCVAb, serum iron, total iron binding capacity, TSAT%, ferritin and hsCRP. Serum hepcidin was analyzed by ELISA technique. Results Serum hepcidin was 26.35±7.26; 40% in stage III, 37.8% in stage IV and 22.2% in stage V. There was statistically significant difference between GFR stages according to Hb., Drug intake ACE inhibitor/ARB, Plt., Creatinine, BUN, Iron, TIBC, Ferritin, T SAT%, CRP and Serum Hepcidin. We showed significant correlations between serum hepcidin and TIC, Iron, TIBC, Ferritin and TSAT%. Conclusion Median hepcidin value is elevated in nondialysis CKD patients due to increased inflammation and decreased clearance of hepcidin. Furthermore, iron status modifies serum hepcidin level and its association with Hb. Increased hepcidin level leads to iron-restricted erythropoiesis and recombinant human EPO (rhEPO) resistance by inhibiting iron absorption from gut and iron recycling from macrophages. Hence, elevated hepcidin can predict need for parenteral iron to overcome hepcidin-mediated iron-restricted erythropoiesis and need for relatively higher rhEPO doses to suppress hepcidin.

Abstract Background Guidelines indicate that a low-protein diet (LPD) delays dialysis in severe chronic kidney disease (CKD). We assessed the value of these guidelines by performing a retrospective analysis in our renal clinical practice. Methods The analysis was performed from 1 January 2010 to 31 March 2018 in 299 CKD Stage 4 patients followed for 70 months in collaboration with a skilled nutritionist. The patients included 43 patients on a controlled protein diet (CPD) of 0.8 g/kg/day [estimated glomerular filtration rate (eGFR) 20–30 mL/min/1.73 m2 body surface (b.s.)], 171 patients on an LPD of 0.6 g/kg/day and 85 patients on an unrestricted protein diet (UPD) who were not followed by our nutritionist (LPD and UPD, eGFR &lt;20 mL/min/1.73 m2 b.s.). Results eGFR was higher in CPD patients than in UPD and LPD patients (21.9 ± 7.4 mL/min/1.73 m2 versus 17.6 ± 8.00 mL/min/1.73 m2 and 17.1 ± 7.5 mL/min/1.73 m2; P = 0.008). The real daily protein intake was higher in UPD patients than in LPD and CDP patients (0.80 ± 0.1 g/kg/day versus 0.6 ± 0.2 and 0.63 ± 0.2 g/kg/day; P = 0.01). Body mass index (BMI) was stable in the LPD and CPD groups but decreased from 28.5 ± 4.52 to 25.4 ± 3.94 kg/m2 in the UPD group (P &lt; 0.001). The renal survival of UPD, LPD and CPD patients was 47.1, 84.3 and 90.7%, respectively, at 30 months (P &lt; 0.001), 42.4, 72.0 and 79.1%, respectively, at 50 months (P &lt; 0.001) and 42.4, 64.1 and 74.4%, respectively, at 70 months (P &lt; 0.001). The LPD patients started dialysis nearly 24 months later than the UPD patients. Diet was an independent predictor of dialysis [−67% of RR reduction (hazard ratio = 0.33; confidence interval 0.22–0.48)] together with a reduction in BMI. Conclusions An LPD recommended by nephrologists in conjunction with skilled dietitians delays dialysis and preserves nutritional status in severe CKD.

Background and Objectives: Patients with chronic kidney disease (CKD) exhibit a highly increased risk of cardiovascular (CV) morbidity and mortality. Subtle changes in left ventricular function can be detected by two-dimensional (2D) speckle tracking echocardiography (STE). This study investigated whether myocardial dysfunction detected by 2D STE may aid in CV and all-cause mortality risk assessment in patients with CKD stages 3 and 4. Method: A study group of 285 patients (CKD 3: 193 patients; CKD 4: 92 patients) and a healthy control group (34 participants) were included in the retrospective study. 2D STE values as well as early and late diastolic strain rates were measured in ventricular longitudinal, circumferential and radial directions. Patients’ CV and all-cause outcome was determined. Results: In the CKD group all measured longitudinal STE values and radial strain were significantly reduced compared to the control group. Cox proportional hazards regression revealed global longitudinal strain to predict CV and all-cause mortality (hazard ratio [HR] 1.15, 95% CI 1.06–1.25; p = 0.0008 and HR 1.09, 95% CI 1.04–1.14; p = 0.0003). After adjustment for sex, age, diabetes, estimated glomerular filtration rate, and preexisting CV disease, this association was maintained for CV mortality and all-cause mortality (HR 1.16, 95% CI 1.06–1.27; p = 0.0019 and HR 1.08, 95% CI 1.03–1.14; p = 0.0026, respectively). Conclusions: The present study shows that 2D STE detects reduced left ventricular myocardial function and allows the prediction of CV and all-cause mortality in patients at CKD stages 3 and 4.

Abstract Background Arterial damage in chronic kidney disease (CKD) is characterized by aortic stiffness. This is seen in elderly patients with advanced CKD. The association between arterial stiffness and early CKD is not well established. Objective: We aimed to study arterial stiffness using pulse wave velocity (PWV) among patients with chronic kidney disease (CKD) stage 2 to 4 and normal renal function in younger-age population. Design and Method: Patients with confirmed CKD stage 2 to 4 were recruited from various clinics from Universiti Teknologi MARA Medical Center, Sungai Buloh, Malaysia from 1st August 2015 until 31st January 2018. Sociodemographic and anthropometric indices were recorded on recruitment. Each patient underwent carotid-femoral (aortic) PWV measurement to determine arterial stiffness. PWV is determined using a one-probe device (SphygmoSore XCEL). Results: 87 patients with CKD stage 2–4 and 87 control patients were recruited. The mean age was 47 ± 5.4 years. CKD patients had a higher mean PWV (7.8 m/s ± 1.7) than healthy controls (5.6 m/s ± 1.0) (p &lt; 0.001, 95% CI –2.59, –1.77). There was significant difference of mean PWV between control (5.6 m/s ± 1.0) and CKD stage 2 (7.6 m/s ± 1.5) (p &lt; 0.001, 95% CI –2.40, –1.49). Our results showed a stepwise increase in PWV from control subjects, CKD stage 2 through stage 4 (p &lt; 0.001). The mean difference of PWV between CKD stage 2 (7.6 m/s, ± 1.5) and stage 4 (9.0 m/s, ± 0.8) was 1.43 (p &lt; 0.001, 95% CI –2.50, -0.35). There was significant difference of mean PWV between diabetes mellitus (DM) (8.2 m/s ± 1.8) and non-DM (7.3 m/s ± 1.3) patients with CKD stage 2–4 (p = 0.022, 95% CI –1.50, –0.12). Mutiple linear regression analysis showed only age (β = 0.078, p = 0.014), mean arterial pressure (MAP) (β = 0.031, p = 0.007) and diuretics usage as the combination antihypertensive medication (β = 0.839, p = 0.018) were independently associated with PWV (r2 = 0.249, p &lt; 0.001). Conclusions: This study shows that arterial stiffness as assessed by PWV occurs early in CKD patient and increased arterial stiffness occurs in parallel with decline of glomerular filtration rate in patients with mild-to-moderate CKD of younger age population.
