Hyperglycemia on Admission Predicts Acute Kidney Failure and Renal Functional Recovery among Inpatients

Background: Hyperglycemia is associated with adverse outcomes in hospitalized patients. We aimed to assess the impact of glucose levels upon admission on the subsequent deterioration or improvement of kidney function in inpatients with a focus on diabetes or reduced baseline kidney function as possible modifiers of this effect. Methods: Running a retrospective cohort analysis, we compared patients with normal vs. high glucose levels upon admission. We applied multivariable logistic regression models to study the association between baseline glucose levels with subsequent renal and clinical outcomes. Interaction terms were used to study a possible modifier effect of diabetes. Results: Among 95,556 inpatients (52% males, mean age 61 years), 15,675 (16.5%) had plasma glucose higher than 180 mg/dL, and 72% of them were diabetics. Patients with higher glucose at presentation were older, with a higher proportion of co-morbid conditions. Rates of acute kidney injury (AKI), acute kidney functional recovery (AKR), and mortality were proportional to reduced renal function. AKI, AKR, and mortality were almost doubled in patients with high baseline glucose upon admission. Multivariable analysis with interaction terms demonstrated an increasing adjusted probability of all events as glucose increased, yet this association was observed principally in non-diabetic patients. Conclusions: Hyperglycemia is associated with AKI, AKR, and mortality in non-diabetic inpatients in proportion to the severity of their acute illness. This association diminishes in diabetic patients, suggesting a possible impact of treatable and easily reversible renal derangement in this population.

The Impact

Abstract Background: Fluid management is an everyday challenge in intensive care units worldwide. Data from recent trials suggest that the use of hydroxyethyl starch leads to a higher rate of acute kidney injury and mortality in septic patients. Evidence on the safety of hydroxyethyl starch used in postoperative cardiac surgery patients is lacking Methods: The aim was to determine the impact of postoperatively administered hydroxyethylstarch 130/0.42 on renal function and 90-day mortality compared to with or without balanced crystalloids in patients after elective cardiac surgery. A retrospective cohort analysis was performed including 2245 patients undergoing elective coronary artery bypass grafting or, aortic valve replacement, or a combination of both between 2015 - 2019. Acute kidney injury was defined according to the ‘kidney disease improving global outcomes’ criteria. Multivariate logistic regression yielded adjusted associations of postoperative hydroxyethyl starch administration with acute kidney injury during hospital stay and 90-day mortality. Linear mixed-effects models predicted trajectories of estimated glomerular filtration rates over the postoperative period to explore the impact of dosage and timing of hydroxyethyl starch administration.Results: A total of 1009 patients (45.0 %) suffered from acute kidney injury. Significantly less acute kidney injury of any stage occurred in patients receiving hydroxyethyl starch compared to patients receiving only crystalloids for fluid resuscitation (43.7 % vs. 51.2 % p=0.008). In multivariate analysis, the administration of hydroxyethyl starch showed a protective effect (OR 0.89 95% confidence interval (CI) (0.82-0.96)) which was less prominent in patients receiving only crystalloids (OR 0.98, 95% CI (0.95-1.00)). No association between hydroxyethyl starch and 90-day mortality (OR 1.05 95% CI (0.88-1.25)) was detected. Renal function trajectories were dose-dependent and biphasic and hydroxyethyl starch could even slow down the late postoperative decline of kidney function.Conclusion: This study showed no association between hydroxyethyl starch and the postoperative occurrence of acute kidney injury and may add evidence to the discussion about the use of hydroxyethyl starch in cardiac surgery patients. In addition, hydroxyethyl starch administered early after surgery in adequate low doses might even prevent the decline of the kidney function after cardiac surgery.

Abstract OBJECTIVES The impact of hypothermic circulatory arrest (HCA) temperature on postoperative acute kidney injury (AKI) has not been evaluated. This study examined the association between circulatory arrest temperatures and AKI in patients undergoing proximal aortic surgery with HCA. METHODS A total of 759 consecutive patients who underwent proximal aortic surgery (ascending ± valve ± root) including arch replacement requiring HCA between July 2005 and December 2016 were identified from a prospectively maintained institutional aortic surgery database. The primary outcome was AKI as defined by Risk, Injury, Failure, Loss, End Stage Renal Disease (ESRD) criteria. The association between minimum nasopharyngeal (NP) and bladder temperatures during HCA and postoperative AKI was assessed, adjusting for patient-level factors using multivariable logistic regression. RESULTS A total of 85% (n = 645) of patients underwent deep hypothermia (14.1–20.0°C), 11% (n = 83) low-moderate hypothermia (20.1–24.0°C) and 4% (n = 31) high-moderate hypothermia (24.1–28.0°C) as classified by NP temperature. When analysed by bladder temperature, 59% (n = 447) underwent deep hypothermia, 22% (n = 170) low-moderate, 16% (n = 118) high-moderate and 3% mild (n = 24) (28.1–34.0°C) hypothermia. The median systemic circulatory arrest time was 17 min. The incidence of AKI did not differ between hypothermia groups, whether analysed using minimum NP or bladder temperature. In the multivariable analysis, the association between degree of hypothermia and AKI remained non-significant whether analysed as a categorical variable (hypothermia group) or as a continuous variable (minimum NP or bladder temperature) (all P > 0.05). CONCLUSIONS In patients undergoing proximal aortic surgery including arch replacement requiring HCA, degree of systemic hypothermia was not associated with the risk of AKI. These data suggest that moderate hypothermia does not confer increased risk of AKI for patients requiring circulatory arrest, although additional prospective data are needed.

The Impact

Blockade of the renin angiotensin system (RAS) reduces albuminuria, attenuates hyperfiltration, and slows the progression of diabetic nephropathy (DN) by preventing vasoconstriction and subsequent increases in glomerular hydrostatic pressure. Since RAS blockade disrupts Ang II signaling in all tissues, the specific contribution of vascular actions of AT1 receptors in DN has been difficult to delineate. Therefore, we generated 129 SvEv mice with cell-specific loss of AT1A from VSMCs (SMKOs) using Cre-loxp . To eliminate AT1R from VSMCs, we crossed the SMKO mice with AT1BR -/- mice, lacking the minor AT1B isoform. To study the impact of vascular AT1R in DN, we crossed the AT1B- null SMKOs with mice having the Ins2 C96Y AKITA mutation, which develop DM1 early. To enhance kidney injury, mice underwent uninephrectomy (UNX) at 11wks. Blood glucose levels were elevated (~500mg/dL) and similar at 10, 16 and 24wks between the two groups. Prior to UNX, albuminuria was similar between Control AKITA and AT1B- null SMKO AKITA (62±10 Control AKITA versus 107±27 μg/24hrs SMKO AKITA, P=NS). Albuminuria increased with age in both Control Akita and AT1B- null SMKO AKITA but without significant differences between the groups at 16wks (307±106 vs 313±117 μg/24hrs; P=NS) or 24wks (494±236 versus 730±217 μg/24hrs; P=NS), despite a trend toward higher albuminuria in AT1B- null SMKO AKITAs. There was no significant difference in GFR (using FITC-inulin) between non-diabetic Control and AT1B- null SMKO (15.6±1.2 vs 14.8±0.8 μl/min/g BW), and hyperfiltration was observed in both Control AKITA (23.7±2.4 μl/min/g BW; P=0.003) and AT1B- null SMKO AKITA mice (20.7±1.7 μl/min/g BW; P=0.01) relative to their non-diabetic comparators. However, there was no significant difference in GFR between ControlAKITA and AT1B- null SMKO AKITA (P=NS). Finally we measured mRNA levels of putative kidney injury markers by RTqPCR and found no differences in levels of Col1A1 , NGAL , or TGFB1 mRNA between Control AKITA and AT1B null SMKO AKITA. Our studies indicate that the absence of vascular AT1R responses is not sufficient to reduce albuminuria and prevent hyperfiltration in a mouse model of DN. This suggests that blockade of AT1R in other cell lineages may contribute to beneficial actions of ARBs in DN.

Background: Myeloperoxidase (MPO) is involved in the initiation, progression, and complications of atherosclerosis in diabetic patients. Objectives: In the current study, the impact of alpha-lipoic acid (LA), a natural antioxidant and a cofactor in the enzyme complexes on MPO, catalase (CAT) and glutathione peroxidase (GPx) activity, glutathione (GSH) and malondialdehyde (MDA) level, histopathology of kidney and expression of antioxidant enzymes, superoxide dismutase (SOD), GPx and CAT which are involved in the detoxification of reactive oxygen species (ROS), was evaluated in alloxan-induced diabetic rats. Materials and Methods: In this study, 30 male Rattus norvegicus rats randomly divided into three groups; control (C), non-treated diabetic (NTD), and LA-treated diabetics (LATD) was induced by alloxan monohydrate (100mg/kg; subcutaneous [SC]). Then treatment was performed with alphaLA (100 mg/kg intraperitoneal (i.p) daily to 6 weeks). Blood sample of animals collected to measure levels of MPO, CAT and GPx activity GSH and MDA. Kidney paraffin sections were prepared to estimate histological studies and to measure quantitative gene expression SOD, GPX and CAT in kidney. Results: Induction of diabetes led to a significant increase in MPO and MDA, reduced GSH level and GPx and CAT activities (P < 0.05). However, treatment with alpha-LA led to a significant elevation in GPx, CAT and GSH levels with a reduction in MPO activities and MDA levels (P < 0.05). Furthermore, the real-time reverse transcriptase-polymerase chain reaction (RT-PCR) analysis results showed increased expressions of GPx, CAT and SOD enzyme in the treatment group compared with the diabetic control group. Histopathological lesions such as increased glomerular volume and lymphocyte infiltration were attenuated in the alpha-LA treated group. Conclusions: Our findings indicated that alpha-LA supplementation is effective in preventing complications induced by oxidative stress and atherosclerosis in diabetic rats.

The Impact

Recent studies have revealed the impact of antibiotic-induced microbiome depletion (AIMD) on host glucose homeostasis. The kidney has a critical role in systemic glucose homeostasis; however, information regarding the association between AIMD and renal glucose metabolism remains limited. Hence, we aimed to determine the effects of AIMD on renal glucose metabolism by inducing gut microbiome depletion using an antibiotic cocktail (ABX) composed of ampicillin, vancomycin, and levofloxacin in mice. The results showed that the bacterial 16s rRNA expression, luminal concentrations of short-chain fatty acids and bile acids, and plasma glucose levels were significantly lower in ABX-treated mice than in vehicle-treated mice. In addition, ABX treatment significantly reduced renal glucose and pyruvate levels. The mRNA expression levels of glucose-6-phosphatase and phosphoenolpyruvate carboxykinase in the renal cortex were significantly higher in ABX-treated mice than in vehicle-treated mice. We further examined the impact of AIMD on the altered metabolic status in mice after ischemia-induced kidney injury. After exposure to ischemia for 60 min, the renal pyruvate concentrations were significantly lower in ABX-treated mice than in vehicle-treated mice. ABX treatment caused a more severe tubular injury after ischemia-reperfusion (IR). Our findings confirm that AIMD is associated with decreased pyruvate levels in the kidney, which may have been caused by the activation of renal gluconeogenesis. Thus, we hypothesized that AIMD would increase the vulnerability of the kidney to IR injury.

The Impact

Acute kidney injury (AKI) is a common problem in hospitalized patients that is associated with significant morbid-mortality. The impact of kidney disease on the excretion of drugs eliminated by glomerular filtration and tubular secretion is well established, as well as the requirement for drug dosage adjustment in impaired kidney function patients. However, since impaired kidney function is associated with decreased activity of several hepatic and gastrointestinal drug-metabolizing enzymes and transporters, drugs doses adjustment only based on kidney alteration could be insufficient in AKI. In addition, there are significant pharmacokinetics changes in protein binding, serum amino acid levels, liver, kidney, and intestinal metabolism in AKI, thus the determination of plasma drug concentrations is a very useful tool for monitoring and dose adjustment in AKI patients. In conclusion, there are many pharmacokinetics changes that should be taken into account in order to perform appropriate drug prescriptions in AKI patients.

The Impact

Introduction: Acute kidney injury following cardiac surgery is a frequent complication associated with increased mortality and morbidity. Minimal invasive extracorporeal circulation is suggested to preserve postoperative renal function. The aim of this study was to assess the impact of minimal invasive versus conventional extracorporeal circulation on early postoperative kidney function. Methods: Randomized controlled trail including 60 patients undergoing elective stand-alone coronary artery bypass graft surgery and allocated in a 1:1 ratio to either minimal invasive (n = 30) or conventional extracorporeal circulation (n = 30). Postoperative kidney injury was assessed by elevation of plasma neutrophil gelatinase-associated lipocalin (NGAL), a sensitive tubular injury biomarker. In addition, we assessed changes in estimated glomerular filtration rate (eGFR), and the incidence of acute kidney injury according to the Acute Kidney Injury Network (AKIN) classification. Results: We observed no differences between groups regarding increase of plasma NGAL (p = 0.31) or decline of eGFR (p = 0.82). In both groups, 6/30 patients developed acute kidney injury according to the AKIN classification, all regaining preoperative renal function within 30 days. Conclusion: Our findings challenge the superiority of minimal invasive compared to conventional extracorporeal circulation in terms of preservation of renal function following low-risk coronary surgery.

ObjectiveTo examine the impact of ACE inhibitor (ACE-I)/angiotensin receptor blocker (ARB) use on rate of SARS-CoV-2 infection and adverse outcomes.MethodsThis nationwide case-control and cohort study included all individuals in Denmark tested for SARS-CoV-2 RNA with PCR from 27 February 2020 to 26 July 2020. We estimated confounder-adjusted ORs for a positive test among all SARS-CoV-2 tested, and inverse probability of treatment weighted 30-day risk and risk ratios (RRs) of hospitalisation, intensive care unit (ICU) admission and mortality comparing current ACE-I/ARB use with calcium channel blocker (CCB) use and with non-use.ResultsThe study included 13 501 SARS-CoV-2 PCR-positive and 1 088 695 PCR-negative individuals. Users of ACE-I/ARB had a marginally increased rate of a positive PCR when compared with CCB users (aOR 1.17, 95% CI 1.00 to 1.37), but not when compared with non-users (aOR 1.00 95% CI 0.92 to 1.09).Among PCR-positive individuals, 1466 (11%) were ACE-I/ARB users. The weighted risk of hospitalisation was 36.5% in ACE-I/ARB users and 43.3% in CCB users (RR 0.84, 95% CI 0.70 to 1.02). The risk of ICU admission was 6.3% in ACE-I/ARB users and 5.4% in CCB users (RR 1.17, 95% CI 0.64 to 2.16), while the 30-day mortality was 12.3% in ACE-I/ARB users and 13.9% in CCB users (RR 0.89, 95% CI 0.61 to 1.30). The associations were similar when ACE-I/ARB users were compared with non-users.ConclusionsACE-I/ARB use was associated neither with a consistently increased rate nor with adverse outcomes of SARS-CoV-2 infection. Our findings support the current recommendation of continuing use of ACE-Is/ARBs during the SARS-CoV-2 pandemic.Trial registration numberEUPAS34887

The Impact

INTRODUCTION:A novel, sensor-based, factory-calibrated Flash Monitoring System (FMS) has recently proved to be an effective alternative to conventional self-monitoring of blood glucose (SMBG) in patients affected by type 1 and type 2 diabetes. The 14-days adhesive sensor, that continuously measures glucose levels in the interstitial fluid, can transfer glucose levels data to a handheld reader or a smartphone equipped with a specific medical app. The uptake of the new technology has been limited so far, because of its high costs. A cost analysis has been conducted to identify the optimal target population of introducing FSM in Veneto.METHODS:The model was designed with a 1-year time horizon for patients with diabetes using intensive insulin in Veneto region. The costs of the new technology was estimated using inputs from the two main randomized controlled trials (the IMPACT study and the REPLACE study) published in the international literature, Regional evidence-based guidelines and administrative database. Resource utilization included strips, lancets, needles, sensors, distribution and patients training. Regional unit costs were adopted.RESULTS:FSM has not shown so far relevant and statically significant benefits in terms of severe adverse events’ reduction. Estimated yearly costs for a FSM user included glucose monitoring, technology training and distribution costs, for a total of EUR1277 per patient. The new technology has been shown to be affordable in diabetic patients with i) 4years<age<18years, ii) continuous subcutaneous insulin infusion and iii) ≥5 blood glucose monitoring per day.CONCLUSIONS:The Veneto Region should carefully consider prescribing extension to other diabetic patients categories, since the high cost of the new technology. A strict prescribing monitoring is strongly recommended with the aim of ensuring appropriateness and avoiding overspending.

Background: Prevention of diabetic complications requires good glycaemic control. This study aimed to provide type 2 diabetes patients with remote active care and glycaemic control through the use of videophone technology without the need for them to attend hospital. The literature recommends additional research to study the impact of technical innovations on improved disease self-management and medical outcome. This is the only study to be conducted in Turkey concerning patient monitoring using videophone technology. The aim of the study was to establish the effectiveness of the use of videophone technology in the glycaemic control of patients with diabetes living in remote areas. Methods: This is a prospective, randomized control study using the systematic sampling method (using half ratio), in which 24 patients were chosen for the Experimental Group (EG) and another 24 for the Control Group (CG). All of the patients agreed to participate in the study. Patients in the CG received routine care, while the glycaemic control and consultations for patients in the EG were conducted using videophone technology. The patients were monitored by videophone for a total of 6 months. The HbA1c and blood glucose values recorded over the 6 month monitoring period were analyzed to determine the effectiveness of using a videophone. Results: The mean age of the individuals in the EG was 54.41 ± 8.54 years (Min=43 Max=78) and in the CG it was 57.25 ± 9.61 (Min=40 Max=77). In both groups, 50% of the individuals were men and 50% were women. When the two groups were compared, it was was found that the preprandial blood glucose levels of the diabetic patients in the EG (mean 159.48 ± 40.71mg/dl) were lower by 13.55 ± 52.89 mg / dl than the preprandial blood glucose levels of the diabetic patients in the CG (mean 173.03 ± 65.07 mg/dl). It was determined at the end of the six-month monitoring that the A1c levels of the individuals in the EG were significinatly lowered by 0.49% in total, and that the A1c levels of the individuals in the CG were higher by 0.17 % in total. Conclusions: It was shown that videophone technology can be useful in the glycaemic control of diabetic patients in Turkey.
