Safety and Metabolic Tolerance of Citrate Anticoagulation in Critically Ill Polytrauma Patients with Acute Kidney Injury Requiring an Early Continuous Kidney Replacement Therapy. Biomedicines 2023; 11:2570. [PMID: 37761011 PMCID: PMC10526994 DOI: 10.3390/biomedicines11092570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 09/15/2023] [Accepted: 09/17/2023] [Indexed: 09/29/2023] Open
Abstract
For severe polytrauma patients with an early AKI requiring renal replacement therapy, anticoagulation remains a great challenge. Due to a high bleeding risk, hemodynamic instability, and increased lactate levels, continuous modality (CKRT) and citrate anticoagulation seem to be the most appropriate. However, their safety with regard to the potential risk of impaired citrate metabolism is not documented. A retrospective study of 60 severe polytrauma patients admitted to the emergency department between January 2000 and December 2021 was conducted; the patients requiring CKRT during the first 72 h were treated with citrate (n. 46, group Citrate) or with heparin (n. 14, group Heparin). Out of 60 patients, 31 survived (51.7%). According to logistic regression analysis, age and SOFA score were significant predictors of mortality. The incidence of rhabdomyolysis was more common in the survivors (77.4 vs. 51.7%), and Kaplan-Meyer analysis showed a better trend towards survival at 90 days for the group Citrate than the group Heparin (p 0.0956). In the group Citrate, hemorrhagic episodes were significantly less common (0.045 vs. 0.273 episodes/day, p < 0.001); the effective duration (h/day) of CKRT was longer; and the effective net ultrafiltration rate (mL/kg/h) and blood flow rate were lower. For severe polytrauma patients, early, soft CKRT with citrate anticoagulation at a low blood flow rate and circuit citratemia showed a better safety and hemodynamic stability, suggesting that citrate should be the first choice anticoagulant in this subset of patients.

Abstract
Background Acute kidney injury (AKI) following severe trauma is common. However, the requirement of renal replacement therapy (RRT) in these patients is rare and is associated with high morbidity and mortality. The primary objective of this study was to identify odds of risk factors, in particular, hypotension at presentation, for the requirement of RRT in patients with AKI following trauma. Methods We performed a case-control study involving patients who were admitted to the intensive care unit (ICU) at a level I trauma center for at least 24 hours. The primary outcome measure was a study of the odds of risk factors associated with the requirement of RRT in such patients. Univariate comparisons and multiple logistic regression analyses were done to identify other risk factors. Results The presence of crush injury, sepsis, and elevated serum creatinine (sCr) on arrival were identified to be independent risk factors for RRT requirement. Hypotension and exposure to radiocontrast or nephrotoxic antimicrobials were not found to be associated with the need for RRT. Acute kidney injury requiring RRT was associated with significantly increased ICU length of stay (15 days vs 5 days; p < 0.001) and higher mortality (83% vs 35%; p < 0.001). Conclusion The presence of crush injury, sepsis, and elevated sCr on presentation were identified to be independent risk factors while hypotension association was insignificant for AKI requiring RRT in our investigation.

Abstract
INTRODUCTION The development of acute kidney injury (AKI) in trauma patients has been associated with almost three fold increase in overall mortality. However, there is a paucity of information of early recognition of risk factors of severe AKI in trauma patients examining the patient's demography, injury characteristics and comorbidities. The purpose of the study was early identification of risk factors of severe AKI. METHODS This retrospective cohort study was performed using 2012-2016, American College of Surgeon Trauma Quality improvement program (ACS-TQIP) data, a national data base of trauma patients in the United State. All adult Trauma patients, age 16 to 89 years old, admitted to the hospital were included in the study. Other variables included; race, sex, initial systolic blood pressure (SBP), SBP<90 mmHg, heart rate, injury severity score (ISS), Glasgow Coma Scale Motor Score (GCSMOT), injury type and patient's comorbidities; diabetes mellitus (DM), hypertension (HTN), congestive heart failure (CHF) and history of smoking. A multiple logistic regression model was used to assess the chance of having severe AKI. The receiver-operating characteristics (ROC) curve was constructed, and the corresponding area-under-the curve (AUC) was calculated. All p values <0.05 was considered statistically significant. RESULTS Out of 935,402 trauma victims, 9,281 (0.99%) patients developed severe AKI. There were significant differences found between the groups (severe AKI presence vs AKI absence), regarding median age [IQR] (61[43-75] vs. 53[32-71]; p<0.001), ISS (18[10-29] vs. 12[9-17]; p<0.001), DM (25.6% vs. 13.2%; p<0.001), HTN (48.6% vs. 33.3%; p<0.001), CHF (9.8% vs. 3.4%; p<0.001) and history of smoking (16.5% vs. 21.3%; p<0.001) on univariate analysis. A multivariable analysis showed all variables above had a significant association of the development of severe AKI except history of smoking. Older age, male gender, high ISS, SBP<90 mmHg, history of DM, HTN, CHF had a higher odds of development of severe AKI. The model showed a moderate strength with area under the curve (AUC) value was 0.750 and the 95% confidence intervals were [0.740, 0.759]. CONCLUSION Current analysis showed certain patients demography, injury characteristics, along with comorbidities are associated with risk of severe AKI.

Abstract
PURPOSE Obesity is a risk factor for the development of acute kidney injury but its effect on the need for dialysis in trauma has not been elucidated. Additionally, the contribution that obesity has towards risk of mortality in trauma is unclear. We hypothesized that patients with a higher body mass index (BMI) will have a higher risk for need of dialysis and mortality after trauma. METHODS This is a retrospective analysis using the National Trauma Data Bank. All patients ≥ 8 years old were grouped based on BMI: normal (18.5-24.99 kg/m2), obese (30-34.99 kg/m2), severely obese (35-39.99 kg/m2) and morbidly obese (≥ 40 kg/m2). The primary outcome was hemodialysis initiation. The secondary outcome was mortality during the index hospitalization. RESULTS From 988,988 trauma patients, 571,507 (57.8%) had a normal BMI, 233,340 (23.6%) were obese, 94,708 (9.6%) were severely obese, and 89,433 (9.0%) were morbidly obese. The overall rate of hemodialysis was 0.3%. After adjusting for covariates, we found that obese (OR 1.36, CI 1.22-1.52, p < 0.001), severely obese (OR 1.89, CI 1.66-2.15, p < 0.001) and morbidly obese (OR 2.04, CI 1.82-2.29, p < 0.001) patients had a stepwise increased need for hemodialysis after trauma. Obese patients had decreased (OR 0.92, CI 0.88-0.95, p < 0.001), severely obese had similar (OR 1.02, CI 0.97-1.08, p = 0.50) and morbidly obese patients had increased (OR 1.06, CI 1.01-1.12, p = 0.011) risk of mortality after trauma. CONCLUSIONS Obesity was associated with an increased risk for dialysis after trauma. Mortality risk was reduced in obese, similar in severely obese, and increased in morbidly obese trauma patients suggesting an inflection threshold BMI for risk of mortality in trauma.

Abstract
Introduction Acute kidney injury (AKI) remains a serious clinical problem in the intensive care unit (ICU). It constitutes an independent risk factor for mortality, especially when renal replacement therapy (RRT) is required. Aim Due to limited evidence pertaining to timing, choice of RRT modality and lack of studies investigating AKI in Polish ICUs, we sought to analyse outcomes of adult AKI-RRT ICU patients in the Silesian Voivodeship. Material and methods We analysed data regarding 1,380 patients with AKI who required RRT (AKI-RRT) (9.2% of all subjects in the registry) hospitalized between October 2011 and December 2014 in Silesian ICUs. The primary outcome was crude ICU mortality. Length of ICU stay (LOS) was considered the secondary outcome. Results Of 15,030 patients 1,380 (9.2%) individuals developed AKI requiring RRT. The overall mortality in the registry was 43.9%, but it was significantly higher (69.1%) in AKI-RRT patients (p < 0.01). Mortality with regard to timing of institution of RRT was 67.1% in the group with RRT instituted prior to ICU admission (RRT-prior-ICU) and 69.4% in patients with RRT instituted during ICU hospitalization (RRT-in-ICU) (p = 0.58). Conclusions Multiple patient- and hospitalization-related factors determine mortality in this specific cohort. There are no differences in mortality with regard to RRT being initiated before or during hospitalization in the ICU. Due to multiple confounders, differences in mortality in terms of modality of RRT should be interpreted with caution.

Abstract
BACKGROUND AND OBJECTIVES Mortality and CKD risk have not been described in military casualties with post-traumatic AKI requiring RRT suffered in the Iraq and Afghanistan wars. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This is a retrospective case series of post-traumatic AKI requiring RRT in 51 military health care beneficiaries (October 7, 2001-December 1, 2013), evacuated to the National Capital Region, documenting in-hospital mortality and subsequent CKD. Participants were identified using electronic medical and procedure records. RESULTS Age at injury was 26±6 years; of the participants, 50 were men, 16% were black, 67% were white, and 88% of injuries were caused by blast or projectiles. Presumed AKI cause was acute tubular necrosis in 98%, with rhabdomyolysis in 72%. Sixty-day all-cause mortality was 22% (95% confidence interval [95% CI], 12% to 35%), significantly less than the 50% predicted historical mortality (P<0.001). The VA/NIH Acute Renal Failure Trial Network AKI integer score predicted 60-day mortality risk was 33% (range, 6%-96%) (n=49). Of these, nine died (mortality, 18%; 95% CI, 10% to 32%), with predicted risks significantly miscalibrated (P<0.001). The area under the receiver operator characteristic curve for the AKI integer score was 0.72 (95% CI, 0.56 to 0.88), not significantly different than the AKI integer score model cohort (P=0.27). Of the 40 survivors, one had ESRD caused by cortical necrosis. Of the remaining 39, median time to last follow-up serum creatinine was 1158 days (range, 99-3316 days), serum creatinine was 0.85±0.24 mg/dl, and eGFR was 118±23 ml/min per 1.73 m(2). No eGFR was <60 ml/min per 1.73 m(2), but it may be overestimated because of large/medium amputations in 54%. Twenty-five percent (n=36) had proteinuria; one was diagnosed with CKD stage 2. CONCLUSIONS Despite severe injuries, participants had better in-hospital survival than predicted historically and by AKI integer score. No patient who recovered renal function had an eGFR<60 ml/min per 1.73 m(2) at last follow-up, but 23% had proteinuria, suggesting CKD burden.

Abstract
Background. Acute kidney injury (AKI) treated with continuous renal replacement therapy (CRRT) is a severe complication in trauma patients. The aim of the study was to assess primary traumatic injuries and secondary organ failures in severe posttraumatic AKI. Methods. Retrospective review of adult trauma patients admitted to the trauma centre at Oslo University Hospital Ullevål. Injury severity score (ISS) was used to assess the severity of primary injuries, and sequential organ failure assessment (SOFA) score was utilized to measure secondary organ failures. Results. Forty-two (8%) of 506 trauma patients admitted to intensive care unit developed AKI treated with CRRT, whereof 40 (95%) suffered blunt trauma mechanisms. Patients had extensive primary organ injuries with median (interquartile range) ISS 36 (27-49). The majority of the patients had respiratory (93% intubated) and cardiovascular (67% with inotropic and/or vasoactive medication) failure within 24 hours after admission. AKI was often part of multiple organ failure, most frequently respiratory and cardiovascular failure, affecting 33 (75%) and 30 (71%) of the patients, respectively. Conclusion. Trauma patients with AKI undergoing CRRT often had severe primary injuries due to blunt trauma. Most of them suffered from secondary multiple organ failure concomitant to AKI.

Abstract
PURPOSE This study aimed to identify the incidence and outcomes of patients with trauma related acute kidney injury (AKI), as defined by RIFLE criteria, at a single level I trauma centre and trauma ICU. METHODS We performed a retrospective observational study of 666 patients admitted to a trauma ICU from a level I trauma unit from March 2008 to March 2011. We conducted multivariable logistic regression to identify independent predictors for AKI and mortality. RESULTS The overall incidence of AKI was 15% (n=102). Median injury severity score (ISS) was 25 (inter quartile range [IQR] 16-34) and mean age was 39 (SD 16.3) in the AKI group. Thirteen patients (13%) were referred with rhabdomyolysis associated renal Failure. Overall mortality in the AKI group was 57% (n=58) but was significantly lower in the rhabdomyolysis Failure group (23% versus 64%; p=0.012). AKI was independently associated with older age, base excess (BE)<-12 (odd ratio [OR] 22.9, 95% confidence interval [CI] 1.89-276.16), IV contrast administration (OR 2.7 95% CI 1.39-5.11) and blunt trauma (OR 2.2 95% CI 1.04-4.71). AKI was an independent predictor of mortality (OR 8.5, 95% CI 4.51-15.95). Thirty-nine (38%) patients required renal replacement therapy. CONCLUSIONS AKI in critically ill trauma patients is an independent risk factor for mortality and is independently associated with increasing age and low BE. Renal replacement therapy utilisation is high in this group and represents a significant health care cost burden.

Abstract
Context: There is a need for identifying risk factors aggravating development of acute renal failure after attaining trauma and defining new parameters for better assessment and management. Aim of the study was to determine the incidence of acute renal failure among trauma patients, and its correlation with various laboratory and clinical parameters recorded at the time of admission and in-hospital mortality. Subjects and Methods: The retrospective cohort study included admitted 208 trauma patients over a period of one year. 135 trauma patients at the serum creatinine level >2.0 mg/dL were enrolled in under the group of acute renal failure. 73 patients who had normal creatinine level made the control group. They were further assessed with clinical details and laboratory investigations. Results: Incidence of acute renal failure was 3.1%. There were 118 (87.4%) males and average length of stay was 9 (1, 83) days. Severity of injury (ISS, GCS) was relatively more among the renal failure group. Renal failure was transient in 35 (25.9%) patients. They had higher incidence of bone fracture (54.0%) (P= 0.04). Statistically significant association was observed between patients with head trauma and mortality 72 (59.0%) (P= 0.001). Prevalence of septic 24 (59.7%) and hemorrhagic 9 (7.4%) shock affected the renal failure group. Conclusion: Trauma patients at the urea level >50 mg/dL, ISS >24 on the first day of admission had 23 times and 7 times the risk of developing renal failure. Similarly, patients with hepatic dysfunction and pulmonary dysfunction were 12 times and 6 times. Patients who developed cardiovascular dysfunction, hematological dysfunction and post-trauma renal failure during the hospital stay had risk for mortality 29, 7 and 8 times, respectively. The final prognostic score obtained was: 14*hepatic dysfunction + 11*cISS + 18*cUrea + 12*cGlucose + 10*pulmonary dysfunction. Optimal score cut-off for prediction of renal failure was found to be ≥25 with specificity, sensitivity and positive likelihood ratio to be 84.9%, 78.4% and 3.9, respectively.

Choice of renal replacement therapy modality and dialysis dependence after acute kidney injury: a systematic review and meta-analysis. Intensive Care Med 2013; 39:987-97. [PMID: 23443311 DOI: 10.1007/s00134-013-2864-5] [Citation(s) in RCA: 176] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2012] [Accepted: 01/27/2013] [Indexed: 01/24/2023]
Abstract
PURPOSE Choice of renal replacement therapy (RRT) modality may affect renal recovery after acute kidney injury (AKI). We sought to compare the rate of dialysis dependence among severe AKI survivors according to the choice of initial renal replacement therapy (RRT) modality applied [continuous (CRRT) or intermittent (IRRT)]. METHODS Systematic searches of peer-reviewed publications in MEDLINE and EMBASE were performed (last update July 2012). All studies published after 2000 reporting dialysis dependence among survivors from severe AKI requiring RRT were included. Data on follow-up duration, sex, age, chronic kidney disease, illness severity score, vasopressors, and mechanical ventilation were extracted when available. Results were pooled using a random-effects model. RESULTS We identified 23 studies: seven randomized controlled trials (RCTs) and 16 observational studies involving 472 and 3,499 survivors, respectively. Pooled analyses of RCTs showed no difference in the rate of dialysis dependence among survivors (relative risk, RR 1.15 [95 % confidence interval (CI) 0.78-1.68], I(2) = 0 %). However, pooled analyses of observational studies suggested a higher rate of dialysis dependence among survivors who initially received IRRT as compared with CRRT (RR 1.99 [95 % CI 1.53-2.59], I (2) = 42 %). These findings were consistent with adjusted analyses (performed in 7/16 studies), which found a higher rate of dialysis dependence in IRRT-treated patients [odds ratio (OR) 2.2-25 (5 studies)] or no difference (2 studies). CONCLUSIONS Among AKI survivors, initial treatment with IRRT might be associated with higher rates of dialysis dependence than CRRT. However, this finding largely relies on data from observational trials, potentially subject to allocation bias, hence further high-quality studies are necessary.

Variability in Uremic Control during Continuous Venovenous Hemodiafiltration in Trauma Patients. Crit Care Res Pract 2012; 2012:869237. [PMID: 22666569 PMCID: PMC3362819 DOI: 10.1155/2012/869237] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2011] [Revised: 02/12/2012] [Accepted: 02/27/2012] [Indexed: 11/17/2022] Open
Abstract
Introduction. Acute kidney injury (AKI) necessitating continuous renal replacement therapy (CRRT) is a severe complication in trauma patients (TP). We wanted to assess daily duration of CRRT and its impact on uremic control in TP. Material and Methods. We retrospectively reviewed adult TP, with or without rhabdomyolysis, with AKI undergoing CRRT. Data on daily CRRT duration and causes for temporary stops were collected from the first five CRRT days. Uremic control was assessed by daily changes in serum urea (Δurea) and creatinine (Δcreatinine) concentrations. Results. Thirty-six TP were included with a total of 150 CRRT days, 17 (43%) with rhabdomyolysis. The median (interquartile range (IQR)) time per day with CRRT was 19 (15–21) hours. There was a significant correlation between daily CRRT duration and Δurea (r = 0.60, P≤0.001) and Δcreatinine (r = 0.43; P = 0.012). CRRT pauses were caused by filter clotting (54%), therapeutic interventions (25%), catheter related problems (10%), filter timeout (6%), and diagnostic procedures (6%). Rhabdomyolysis did not affect the CRRT data. Conclusions. TP undergoing CRRT had short daily CRRT duration causing reduced uremic control. Clinicians should modify their daily clinical practice to improve technical skills and achieve sufficient dialysis dose.
