Abstract Background: Patients suffering from acute kidney injury (AKI) have been associated with impaired sodium. However, studies on the association of dysnatremia with all-cause mortality risk in AKI patients are particularly lacking. We examined the relationship between different levels of serum sodium and mortality among very elderly patients with AKI. Methods: We retrospectively enrolled very elderly patients (≥ 75 years) from Chinese PLA General Hospital from 2007, to 2018. All-cause mortality was examined according to eight predefined sodium levels: <130.0 mmol/L, 130.0–134.9 mmol/L, 135.0–137.9 mmol/L, 138.0–141.9 mmol/L, 142.0–144.9 mmol/L, 145.0–147.9 mmol/L, 148.0–151.9 mmol/L, and ≥152.0 mmol/L. We estimated the risk of all-cause mortality using a multivariable adjusted Cox proportional hazard model, with a normal serum potassium level of 135.0–137.9 mmol/L as a reference. Results: In total, 744 geriatric patients were suitable for the final evaluation. Among them, 260 (34.9%) died within 90 days; during the 1-year follow-up, 5 patients were lost to follow-up, and 383 (51.8%) died. After 90 days, the mortality rates in the eight strata were 36.1, 27.8, 19.6, 24.4, 30.7, 48.6, 52.8, and 57.7%, respectively. In the multivariable adjusted analysis, patients with sodium levels <130.0 mmol/L [hazard ratio (HR): 2.247; 95% confidence interval (CI): 1.117–4.521], from 142.0 to 144.9 mmol/L (HR: 1.964; 95% CI: 1.100–3.508), from 145.0 to 147.9 mmol/L (HR: 2.942; 95% CI: 1.693–5.114), from 148.0 to 151.9 mmol/L (HR: 3.455; 95% CI: 2.009–5.944), and ≥152.0 mmol/L (HR: 3.587; 95% CI: 2.151–5.983) had an increased risk of all-cause mortality. After 1 year, the mortality rates in the eight strata were 58.3, 47.8, 33.7, 38.9, 45.5, 64.3, 69.4, and 78.4%, respectively. In the multivariable adjusted analysis, patients with sodium levels <130.0 mmol/L (HR: 1.944; 95% CI: 1.125–3.360), from 142.0 to 144.9 mmol/L (HR: 1.681; 95% CI: 1.062–2.660), from 145.0 to 147.9 mmol/L (HR: 2.631; 95% CI: 1.683–4.112), from 148.0 to 151.9 mmol/L (HR: 2.411; 95% CI: 1.552–3.744), and ≥152.0 mmol/L (HR: 3.037; 95% CI: 2.021–4.563) had an increased risk of all-cause mortality. Conclusion: Sodium levels outside the interval of 130.0–141.9 mmol/L were associated with increased risks of 90-day mortality and 1-year mortality in very elderly AKI patients.

Abstract Acute kidney injury (AKI) has an incidence rate of 5-6% among intensive care unit (ICU) patients and sepsis is the most frequent etiology. Aims: To assess patients in the ICU that developed AKI, AKI on chronic kidney disease (CKD), and/or sepsis, and identify the risk factors and outcomes of these diseases. Methods: A prospective observational cohort quantitative study that included patients who stayed in the ICU > 48 hours and had not been on dialysis previously was carried out. Results: 302 patients were included and divided into: no sepsis and no AKI (nsnAKI), sepsis alone (S), septic AKI (sAKI), non-septic AKI (nsAKI), septic AKI on CKD (sAKI/CKD), and non-septic AKI on CKD (nsAKI/CKD). It was observed that 94% of the patients developed some degree of AKI. Kidney Disease Improving Global Outcomes (KDIGO) stage 3 was predominant in the septic groups (p = 0.018). Nephrologist follow-up in the non-septic patients was only 23% vs. 54% in the septic groups (p < 0.001). Dialysis was performed in 8% of the non-septic and 37% of the septic groups (p < 0.001). Mechanical ventilation (MV) requirement was higher in the septic groups (p < 0.001). Mortality was 38 and 39% in the sAKI and sAKI/CKD groups vs 16% and 0% in the nsAKI and nsAKI/CKD groups, respectively (p < 0.001). Conclusions: Patients with sAKI and sAKI/CKD had worse prognosis than those with nsAKI and nsAKI/CKD. The nephrologist was not contacted in a large number of AKI cases, except for KDIGO stage 3, which directly influenced mortality rates. The urine output was considerably impaired, ICU stay was longer, use of MV and mortality were higher when kidney injury was combined with sepsis.

Abstract BackgroundHashimoto’s thyroiditis is typically diagnosed incidentally from elevated TSH or after evaluation of suggestive symptoms, including weight gain and fatigue. Rarely, patients present with an initial hyperthyroid state, Hashitoxicosis, that lasts weeks to months. Through a review of the current literature, it became apparent that this case is unique in several ways: the patient’s age, lack of comorbid conditions, the unique presentation of her thyroid disease, as well as the development of acute kidney injury while hospitalized.Case PresentationHere we present the case of a 26-year-old female who was referred to the Endocrinology office in July 2019 with symptoms of hyperthyroidism. She has a positive family history of Graves’ disease (GD) in her mother and thyroid malignancy in her maternal aunt. On her initial visit, TSH was suppressed, free thyroid hormones were increased, and both TPO and TSI antibodies were elevated. It was determined that this was likely a presentation of GD, and the patient was started on methimazole. She was instructed to follow-up every four weeks for monitoring of symptoms and labs. Three months following the initial visit, the patient failed to follow-up in office. During this time, she was seen by her primary care physician, diagnosed with hyperlipidemia, and started on statin therapy. One month later, on a subsequent follow-up with endocrinology, the patient complained of new onset back pain, muscle cramps, weight gain, and cold intolerance. She was sent to the emergency department for work-up. Evaluation revealed rhabdomyolysis in the setting of severe hypothyroidism, complicated by acute kidney injury. Her final diagnosis was found to be Hashitoxicosis with subsequent hypothyroidism.ConclusionsHyper- and hypothyroidism are two extremes on the spectrum of autoimmune thyroid disease, and the presentation can vary from patient-to-patient. Rarely, severe hypothyroidism can present with rhabdomyolysis with increased risk in patients on statin therapy. Thus, it is important to ensure patients are clinically and biochemically euthyroid prior to initiation of statin therapy. This case emphasizes the need for communication among physicians and the importance of patient adherence to treatment plans.

Abstract BackgroundHeterogeneity exists in sepsis-associated acute kidney injury (SA-AKI). This prospective observational cohort study aimed to perform consensus cluster analysis and investigate the clinical relevance of identified sub-phenotypes of critically ill patients with dialysis-requiring SA-AKI.MethodsAll septic patients with dialysis-requiring SA-AKI, defined by the Sepsis-3 and Kidney Disease: Improving Global Outcomes AKI criteria, admitted to an intensive care unit in Taiwan between 2002 and 2018 were included. We employed unsupervised consensus clustering based on 22 clinical variables upon initialising renal replacement therapy. They were observed until death or 90 days after hospital discharge. The outcomes were mortality and being free of dialysis.ResultsIn total, 1,397 patients were enrolled (mean age of 63.8 ± 16.38 years and 69.7% were men). After a median follow-up period of 31 (interquartile range 8-123) days, all-cause mortality occurred in 911 patients (65.12%). Moreover, 133 (9.51%) survivors were dialysis dependent, where 355 (25.38%) survivors were free of dialysis. Unsupervised consensus clustering identified three sub-phenotypes associated with significantly different risks of mortality and being free of dialysis. This strategy led us to reveal that the pre-dialysis hyperlactatemia of ≥ 3.1 mmol/L was an independent predictor of mortality and being free of dialysis according to the competing risk modeling. Our results were validated in an independent multi-center AKI cohort.ConclusionsBy the data-driven clustering analysis, we identified sub-phenotypes in septic patients with dialysis-requiring SA-AKI and revealed pre-dialysis hyperlactatemia as a novel outcome predictor. This result represents a step towards precision medicine for septic patients.

Abstract The incidence of acute kidney injury (AKI) has increased in the past decades. AKI complicates up to 15% of hospitalizations and can reach up to 50–60% in critically ill patients. Besides the short-term impact of AKI in patient outcomes, several studies report the association between AKI and adverse long-term outcomes, such as recurrent AKI episodes in 25–30% of cases, hospital re-admissions in up to 40% of patients, an increased risk of cardiovascular events, an increased risk of progression of chronic kidney disease (CKD) after AKI and a significantly increased long-term mortality. Despite the long-term impact of AKI, there are neither established guidelines on the follow-up care of AKI patients, nor treatment strategies to reduce the incidence of sequelae after AKI. Only a minority of patients have been referred to nephrology post-discharge care, despite the evidence of improved outcomes associated with nephrology referral by addressing cardiovascular risk and risk of progression to CKD. Indeed, AKI survivors should have specialized nephrology follow-up to assess kidney function after AKI, perform medication reconciliation, educate patients on nephrotoxic avoidance and implement strategies to prevent CKD progression. The authors provide a comprehensive review of the transition from AKI to CKD, analyse the current evidence on the long-term outcomes of AKI and describe predisposing risk factors, highlight the importance of follow-up care in these patients and describe the current therapeutic strategies which are being investigated on their impact in improving patient outcomes.

Objective Contrast-enhanced computed tomography angiography (CTA) is commonly used to investigate acute abdominal conditions, but the risk of contrast-induced acute kidney injury (CI-AKI) has been poorly investigated in patients with acute mesenteric ischemia. The aim of the present study was to evaluate the incidence of CI-AKI in these patients and identify potential predictive factors. Methods Patients admitted for acute mesenteric ischemia who had a diagnostic CTA with contrast medium and a follow-up of creatinine concentration were retrospectively included. Results Among 53 patients included, 9 (16.9%) developed CI-AKI. The prevalence of chronic kidney disease did not differ significantly between those who developed CI-AKI and those who did not (33.3 vs 18.2%, p=.372). Plasma total bilirubin and conjugated bilirubin levels were significantly higher in patients who developed CI-AKI (17.5 vs 8.0 μmol/L, p=.013 and 8.0 vs 3.0 μmol/L, p=.031, respectively). The proportion of patients who had revascularization was similar between patients who developed CI-AKI and those who did not (11.1 vs 20.5%, p>.999). No significant difference was observed for 30-day mortality and all-cause mortality for a median follow-up of 168 days (22.2 vs 13.6%, p=.611; and 33.3 vs 61.4%, p=.153, respectively). Conclusion This study reports the incidence of CI-AKI in patients with acute mesenteric ischemia after diagnostic CTA with contrast medium. Plasma bilirubin levels were a predictive factor of CI-AKI in these patients. The administration of contrast media during revascularization was not associated with an increased risk of CI-AKI.

Background: Acute kidney injury (AKI) was found to be associated with an increased risk of major adverse cardiovascular events (MACE) in the general population. Patients after kidney transplantation are prone to AKI events and are also at an increased risk of cardiovascular (CV) disease. The association between AKI and MACE in kidney transplant patients is yet to be studied. Methods: This retrospective single-center cohort study reviewed 416 adult renal allograft recipients transplanted between 2005 and 2010. AKI events were recorded starting 2 weeks after transplantation, or following discharge with a functioning graft. AKI was defined, according to the KDIGO criteria. The primary outcome was the composite of MACE starting 6 months after transplantation and all-cause mortality. For survival analysis, we used univariate and multivariate time varying Cox proportional hazard model. Results: One hundred and twenty-four patients (29.8%) had at least one episode of AKI. During the median follow-up time of 7.2 years (interquartile range 4.3–9.1), 144 outcome events occurred. By time varying Cox regression analysis, AKI was associated with an increased rate of CV outcomes or death (hazard ratio [HR] 1.96, 95% CI 1.36–2.81, p < 0.001), and the association remained significant by multivariate adjusted model (HR 1.76, 95% CI 1.18–2.63, p = 0.005). As for the different components of MACE, all-cause mortality and CV mortality were the only outcomes that were significantly associated with AKI. No interaction between AKI timing and MACE was found. Conclusion: AKI in kidney transplant recipient is associated with an increased risk of CV disease.

Fgf 23

Background Fibroblast growth factor (FGF)-23 levels rise as kidney function declines. Whether elevated FGF-23 levels are associated with an increased risk for contrast-associated acute kidney injury (CA-AKI) and major adverse cardiovascular events (MACE) in patients undergoing coronary angiography remain uncertain. Methods In total, 492 patients receiving coronary angiography were enrolled. Their serum FGF-23 levels were measured before administration of contrast media. The occurrence of CA-AKI was defined as a rise in serum creatinine of 0.5 mg/dL or a 25% increase from the baseline value within 48 h after the procedure. All patients were followed up for at least 1 year or until the occurrence of MACE including death, nonfatal myocardial infarction (MI), and ischemic stroke. Results Overall, CA-AKI occurred in 41 (8.3%) patients. During a median follow-up of 2.6 years, there were 24 deaths, 3 nonfatal MIs, and 7 ischemic strokes. Compared with those in the lowest FGF-23 tertile, individuals in the highest FGF-23 tertile had a significantly higher incidence of CA-AKI (P < 0.001) and lower incidence of MACE-free survival (P = 0.001). In multivariate regression analysis, higher FGF-23 level was found to be independently associated with a graded risk for CA-AKI (OR per doubling, 1.90; 95% CI 1.48–2.44) and MACE (HR per doubling, 1.25; 95% CI 1.02–1.52). Conclusions Elevated FGF-23 levels were associated with an increased risk for CA-AKI and future MACE among patients undergoing coronary angiography. FGF-23 may play a role in early diagnosis of CA-AKI and predicting clinical outcomes after coronary angiography.

Background: The number of elderly patients undergoing pacemaker (PM) implantation is constantly growing. However, information on survival and prognostic factors of this particular patient group is scarce. The objective of this study was to determine the survival of elderly and very elderly patients undergoing PM implantation, as well as to investigate prognostic factors of mortality. Methods: This is a retrospective observational study of a single center. Patients ≥ 80 years of age, that underwent PM implantation between January 2017 and December 2018 in our center, were included for chart review. Very elderly patients were defined as those with ≥ 90 years of age. Results: A total of 269 patients were included in the study with a mean age of 85 (±4.1) years. 53 patients were ≥ 90 years of age. 52% of the patients were male. 24.5% of the elderly patients and 41.5% of the very elderly patients received a single chamber PM. Median follow-up time was 28 (14-30) months, with no significant differences between the two groups of patients. The mortality rate for elderly patients was 15.7% for the elderly and 32.1% for the very elderly (p = 0.002). Generating multivariate Cox regression models, the following parameters showed to be significant predictors of all-cause mortality: Age (1.37 (1.02-1.29), p = 0.005), chronic kidney disease (5.57 (2.47-12.56), p<0.001), COPD (3.74 (1.19-11.55), p = 0.023) and cancer (3.57 (1.02-12.51), p = 0.046). In the group of the very elderly only age (1.58 (1.10-2.27), p = 0.014) and cancer (3.76 (2.38-4.18), p = 0.003) significantly predicted mortality. Conclusion: Our study shows a good life expectancy of elderly and very elderly patients that underwent PM implantation, with a survival rate that is comparable to the general population. The primary prognostic factors were non-cardiological and comorbidities, such as chronic kidney disease, cancer and COPD, had a stronger association with mortality than age.
