Association of Prediabetes With CKD Progression and Adverse Cardiovascular Outcomes: An Analysis of the CRIC Study

Abstract Purpose Despite our understanding of diabetes as an established risk factor for progressive kidney disease and cardiac complications, the prognostic significance of prediabetes in patients with chronic kidney disease (CKD) remains largely unknown. Methods Participants of the Chronic Renal Insufficiency Cohort (CRIC) were categorized as having normoglycemia, prediabetes, or diabetes according to fasting plasma glucose, glycated hemoglobin A1c (HbA1c), and treatment with antidiabetic drugs at baseline. Unadjusted and adjusted proportional hazards models were fit to estimate the association of prediabetes and diabetes (versus normoglycemia) with: (1) composite renal outcome (end-stage renal disease, 50% decline in estimated glomerular filtration rate to ≤ 15 mL/min/1.73 m2, or doubling of urine protein-to-creatinine ratio to ≥ 0.22 g/g creatinine); (2) composite cardiovascular (CV) outcome (congestive heart failure, myocardial infarction or stroke); and (3) all-cause mortality. Results Of the 3701 individuals analyzed, 945 were normoglycemic, 847 had prediabetes and 1909 had diabetes. The median follow-up was 7.5 years. Prediabetes was not associated with the composite renal outcome (adjusted hazard ratio [aHR] 1.13; 95% confidence interval [CI], 0.96–1.32; P = 0.14), but was associated with proteinuria progression (aHR 1.23; 95% CI, 1.03–1.47; P = 0.02). Prediabetes was associated with a higher risk of the composite CV outcome (aHR 1.38; 95% CI, 1.05–1.82; P = 0.02) and a trend towards all-cause mortality (aHR 1.28; 95% CI, 0.99–1.66; P = 0.07). Participants with diabetes had an increased risk of the composite renal outcome, the composite CV outcome, and all-cause mortality. Conclusions In individuals with CKD, prediabetes was not associated with composite renal outcome, but was associated with an increased risk of proteinuria progression and adverse CV outcomes.

Background: Sleeping disorder has been associated with chronic kidney disease (CKD); however, the correlation between sleeping pills use and CKD has not been investigated in-depth yet. This study elucidated the potential association of sleeping pill use with the risk of CKD and CKD progression to end-stage renal disease (ESRD) requiring dialysis.Methods: This study was based on a population-based cohort that included 209,755 sleeping pill users among 989,753 individuals. After applying the exclusion criteria, 186,654 sleeping pill users and 373,308 nonusers were enrolled to monitor the occurrence of CKD. Using a cumulative daily dose, we analyzed the types of sleeping pills related to the risk of CKD and ESRD. Propensity score matching and analysis using Cox proportional hazards regression were performed with adjustments for sex, age, and comorbidities.Results: Sleeping pill use was related to increased CKD risk after adjusting for underlying comorbidities (adjusted hazard ratio [aHR] = 1.806, 95% confidence interval [CI]: 1.617–2.105, p < 0.001). With the exception of hyperlipidemia, most comorbidities correlated with an increased risk of CKD. Persistent use of sleeping pills after CKD diagnosis increased the risk of concurrent ESRD (aHR = 7.542; 95% CI: 4.267–10.156; p < 0.001). After the subgroup analysis for sleeping pill use, brotizolam (p = 0.046), chlordiazepoxide (p < 0.001), clonazepam (p < 0.001), diazepam (p < 0.001), dormicum (p < 0.001), estazolam (p < 0.001), fludiazepam (p < 0.001), flunitrazepam (p < 0.001), nitrazepam (p < 0.001), trazodone (p < 0.001), zolpidem (p < 0.001), and zopiclone (p < 0.001) were found to have significant correlation with increased CKD risk.Conclusion: Sleeping pill use was related to an increased risk of CKD and ESRD. Further studies are necessary to corroborate these findings.

The Impact

ABSTRACT Background Obesity is a risk factor for de novo chronic kidney disease (CKD) in the general population. Obesity has been increasingly prevalent in patients with CKD and may lead to further progression of pre-existing CKD. However, whether obesity is associated with the development of end-stage renal disease (ESRD) in patients with CKD is not well understood. Objective We investigated the impact of obesity on ESRD (needing chronic dialysis treatment or pre-emptive renal transplantation) or all-cause mortality in patients with moderate to advanced CKD. Design A total of 322 patients with stages 3–5 CKD who were not yet on dialysis were prospectively followed for a median of 4.9 y. Obesity was defined by body mass index (BMI, in kg/m2) ≥30 or body fat percentage (BF%) >25% in men and >35% in women. BF% was assessed with the use of the Body Composition Monitor, a multifrequency bioimpedance spectroscopy device. Results In total, 100 participants progressed to ESRD and 39 participants died. Obesity, whether defined by BMI or BF%, was not associated with a significantly increased risk of ESRD in Cox proportional hazards models that adjusted for age, sex, diabetes mellitus, cardiovascular disease, estimated glomerular filtration rate, urine protein:creatinine ratio, high-sensitivity C-reactive protein, and use of renin-angiotensin-aldosterone system inhibitors or statins, accounting for the competing risk for mortality (subdistribution HR: 1.15; 95% CI: 0.62, 2.14 for BMI-defined obesity and subdistribution HR: 0.84, 95% CI: 0.54, 1.29 for BF%-defined obesity, respectively). Results were similar when BMI and BF% were analyzed as continuous or time-dependent variables. Whereas higher BMI was protective, higher BF% appeared to be associated with increased all-cause mortality. Conclusions Obesity did not confer an increased risk of ESRD in patients with moderate to advanced CKD. This trial was registered at http://www.clinicaltrials.gov as NCT03285074.

Background: Little is known about how incident atrial fibrillation (AF) affects the clinical outcomes in chronic kidney disease (CKD) patients and whether there is a different influence between pre-existing and incident AF. Methods: Incident CKD patients from 2000 to 2013 were retrieved from the National Health Insurance Research Database (NHIRD) of Taiwan and they were classified as non-AF (n = 15,251), prevalent AF (n = 612), and incident AF (n = 588). The outcomes of interest were end-stage renal disease (ESRD) requiring dialysis, all-cause mortality, cardiovascular (CV) mortality, acute myocardial infarction (AMI), stroke or systemic thromboembolism. Results: Compared with CKD patients without AF, those with prevalent or incident AF were associated with higher adjusted rates of ESRD (hazard ratio (HR), 1.40; 95% confidence interval (CI), 1.32–1.48; HR, 2.91; 95% CI, 2.74–3.09, respectively), stroke or systemic thromboembolism (HR, 1.89; 95% CI, 1.77–2.03; HR, 1.67; 95% CI, 1.54–1.81, respectively), AMI (HR, 1.24; 95% CI, 1.09–1.41; HR, 1.99; 95% CI, 1.75–2.27, respectively), all-cause mortality (HR, 1.64; 95% CI, 1.56–1.72; HR, 2.17; 95% CI, 2.06–2.29, respectively), and CV mortality (HR, 2.95; 95% CI, 2.62–3.32; HR, 4.61; 95% CI, 4.09–5.20, respectively). Intriguingly, CKD patients with prevalent AF were associated with lower adjusted rates of ESRD, AMI, all-cause mortality, and CV mortality compared with those with incident AF. Conclusion: Both incident and prevalent AF were independently associated with greater risks of AMI, all-cause mortality, CV mortality, ESRD, and stroke or systemic thromboembolism. Our findings are novel in that, compared with prevalent AF, incident AF possessed an even higher risk of some clinical consequences, including ESRD, all-cause mortality, CV mortality, and AMI.

Background: Patients with chronic kidney disease (CKD) are at increased risk of bleeding and transfusion after cardiac catheterization. Whether rates of these complications or progression to new dialysis are increased in this high-risk population undergoing transradial (TR) access compared to transfemoral (TF) access is unknown. Methods: From the Veterans Affairs Clinical Assessment, Reporting, and Tracking (CART) Program between 10/2007-09/2012 we identified 40,160 CKD patients undergoing cardiac catheterization with baseline glomerular filtration rate (GFR) ≤ 60 ml/min. We used multivariable Cox modeling to determine the independent association between TR access and post-procedure transfusion as well as progression to new dialysis using TF as the reference. Results: Overall, 3,828 (9.5%) of CKD patients underwent TR access and tended to be slightly younger but overall had similar rates of CKD severity compared with TF patients (GFR 45-60 ml/min: 77.0% vs. 77.0%; GFR 30-44 ml/min: 19.7% vs. 19.3%; GFR 15-29 ml/min: 3.3% vs. 3.7%, p=0.35). TR patients had longer fluoroscopy times (8.1 vs 6.9 minutes, p=<0.0001) but decreased contrast use (90.0 vs 100.0 ml, p=<0.0001). Among the 31,692 patients with a full year of follow-up, 42 (1.7%) of TR patients and 545 (1.9%) of TF patients progressed to new dialysis within 1 year (p=0.64). However, only 33 (0.9%) of TR patients compared with 570 TF patients (1.6%) needed post-procedure blood transfusion (p=0.0006). After multivariable adjustment, there was no significant difference in progression to ESRD between TR and TF patients but TR was associated with a significant decrease in transfusion (Figure). Conclusion: Among CKD patients undergoing cardiac catheterization in the VA health system, TR access is associated with a decreased risk for post-procedure transfusion compared with TF access. There was no significant difference between the two approaches with respect to progression to ESRD. These data suggest that TR is a reasonable option for patients with any level of CKD undergoing cardiac catheterization.

Abstract Introduction Lithium is established as an effective treatment of mania, of depression in bipolar and unipolar disorder, and in maintenance treatment of these disorders. However, due to the necessity of monitoring and concerns about irreversible adverse effects, in particular renal impairment, after long-term use, lithium might be underutilized. Methods This study reviewed 6 large observational studies addressing the risk of impaired renal function associated with lithium treatment and methodological issues impacting interpretation of results. Results An increased risk of renal impairment associated with lithium treatment is suggested. This increased risk may, at least partly, be a result of surveillance bias. Additionally, the earliest studies pointed toward an increased risk of end-stage renal disease associated with lithium treatment, whereas the later and methodologically most sound studies do not. Discussion The improved renal outcome found in the more recent lithium studies may be a result of improved monitoring and focus on recommended serum levels (preferentially 0.6–0.8 mmol/L) as compared to poorer renal outcome in studies with patients treated in the 1960s to 1980s.

Abstract Background and Aims Plasma potassium levels are impacted by decreased kidney function and are known to be associated with increased mortality, adverse cardiovascular events and adverse kidney events. However, the prognostic implication of urinary potassium is unclear. Method We conducted an observational study of 1102 patients with chronic kidney disease (CKD) who were hospitalized between 2010 and 2018. The expected primary outcomes were all-cause mortality, adverse cardiovascular events and CKD progression. CKD progression was defined as a 30% increase in serum creatinine, the initiation of maintenance dialysis or the need for kidney transplantation. The Cox proportional hazards model was used to analyse the association between urinary potassium excretion and adverse clinical outcomes after adjustment for potential confounders. Results At baseline, 66% of the patients were men, with a median age of 72 years (interquartile range or IQR, 64–79 years); 61% of the patients were diabetic, and 54% of them were hypertensive. The median values for estimated glomerular filtration rate (eGFR) was 12 mL/min/1.73m2 (IQR, 8–18), serum potassium 4.5 mmol/L (IQR, 4.1–5.1) and urinary potassium/creatinine ratio (UK/Cr) 27 mmol/gCr (IQR, 20–38). Over a median follow-up period of 2.6 years (IQR 0.2–4.5), the number of all-cause deaths was 87. There were 171 cases of cardiovascular events and 860 cases of CKD progression. After adjusting for the eGFR, serum potassium level, proteinuria, renin–angiotensin system inhibitors, diuretics and other potential confounders, UK/Cr was found to be neither significantly associated with all-cause mortality nor with adverse cardiovascular events. However, a low UK/Cr was associated with an increased risk of CKD progression (adjusted hazard ratio [95% confidence interval] for the first, second and third quartiles, compared with the fourth quartile, were as follows: 2.09 [1.43-3.06], 1.33 [0.96-1.86] and 1.05 [0.75-1.46]) Conclusion A low UK/Cr might be an independent risk factor for poor renal outcome.

Abstract Background There is little information in haemodialysis (HD) patients on whether temporal changes in serum calcium, phosphate or intact parathyroid hormone (iPTH) are associated with mortality. Methods We analysed associations of phosphate, total calcium and iPTH with all-cause and cardiovascular mortality in 8817 incident HD patients from the European second Analyzing Data, Recognizing Excellence and Optimizing Outcomes (AROii) cohort enrolled in 2007–09, which were prospectively followed for a median of 3 years, using time-dependent Cox proportional hazards models. We evaluated changes in risk over time depending on changes in phosphate, calcium or iPTH. Results The association of phosphate and iPTH with all-cause mortality was U-shaped, with the lowest risk ranges between 1.20 and 1.89 mmol/L for phosphate and between 239 and 710 ng/L for iPTH. For total calcium, the associations were J-shaped, with an increased risk for all-cause mortality at levels >2.36 mmol/L. Lowest risk ranges for cardiovascular mortality did not change markedly for all three parameters. If iPTH was below the lowest risk range at baseline (iPTH <239 ng/L), a subsequent increase in levels was associated with improved survival. For phosphate, an increase or decrease out of the lowest risk range was associated with increased mortality risk. For calcium, this was only the case when the values increased above the lowest risk range. Conclusion In the AROii cohort, the ranges of bone mineral biomarkers associated with the lowest mortality ranges were largely consistent with the current Kidney Disease: Improving Global Outcomes chronic kidney disease–mineral and bone disorder guideline recommendations. Allowing a suppressed iPTH to increase was associated with a lower mortality, whereas shifts of phosphate or calcium outside the lowest risk range increased mortality.

Chronic kidney disease (CKD) in patients with type 2 diabetes (T2D) is associated with increased risk of end-stage renal disease (ESRD) and cardiovascular disease (CVD). Urine albumin-to-creatinine ratio (UACR) is a sensitive and early indicator of kidney damage, which should be used routinely to accurately assess CKD stage and monitor kidney health. However, this test currently is performed in only a minority of patients with T2D. Here, we review the importance of albuminuria testing and current barriers that hinder patient access to UACR testing and describe solutions to such testing in a community clinical setting.

Prevalence Ratios

Chronic kidney disease (CKD) is associated with an increased risk for cardiovascular events, hospitalizations, end stage renal disease and mortality. Main risk factors for CKD are diabetes, hypertension, and older age. Although CKD prevalence is about 10%, awareness for CKD is generally low in patients and physicians, hindering early diagnosis and treatment. We analyzed baseline data of 3305 participants with CKD Stages 1–4 from German cohorts and registries collected in 2010. Prevalence of CKD unawareness and prevalence ratios (PR) (each with 95%-confidence intervals) were estimated in categories of age, sex, CKD stages, BMI, hypertension, diabetes and other relevant comorbidities. We used a log-binomial regression model to estimate the PR for CKD unawareness for females compared to males adjusting for CKD stage and CKD risk factors. CKD unawareness was high, reaching 71% (68–73%) in CKD 3a, 49% (45–54%) in CKD 3b and still 30% (24–36%) in CKD4. Prevalence of hypertension, diabetes or cardiovascular comorbidities was not associated with lower CKD unawareness. Independent of CKD stage and other risk factors unawareness was higher in female patients (PR = 1.06 (1.01; 1.10)). Even in patients with CKD related comorbidities, CKD unawareness was high. Female sex was strongly associated with CKD unawareness. Guideline oriented treatment of patients at higher risk for CKD could increase CKD awareness. Patient–physician communication about CKD might be amendable.

Background Targeting higher hemoglobin levels with erythropoietin to treat anemia in patients with chronic kidney disease is associated with increased cardiovascular risk, including that of stroke. The risks of the subtypes of stroke, ischemic, hemorrhagic, and unspecified, following the administration of erythropoietin in patients with end‐stage renal disease receiving hemodialysis remain unclear. Methods and results Overall, 12 948 adult patients with end‐stage renal disease treated during 1999 to 2010 who had undergone hemodialysis were included. The study end points were the incidences of stroke and its subtypes. We used Cox proportional hazards regression models to estimate hazard ratios (HRs) of stroke and its subtypes in erythropoietin recipients compared with nonrecipients. Patients in the erythropoietin cohort did not have an increased risk of stroke compared with those in the nonerythropoietin cohort (adjusted HR, 1.03; 95% CI, 0.92–1.15). Compared with patients in the nonerythropoietin cohort, the risks of ischemic, hemorrhagic, or unspecified stroke were not higher in patients in the erythropoietin cohort (adjusted HRs, 1.08 [95% CI, 0.93–1.26], 0.96 [95% CI, 0.78–1.18], and 1.03 [95% CI, 0.80–1.32], respectively). Increased risks of stroke and its subtypes were not observed with even large annual defined daily doses of erythropoietin (>201). Conclusions Erythropoietin in patients receiving hemodialysis is not associated with increased risk of stroke or any of its subtypes.
