Dyschloremia is associated with failure to restore renal function in survivors with acute kidney injury: an observation retrospective study

AbstractDyschloremia is common in critically ill patients. However, little is known about the effects of dyschloremia on renal function in patients with acute kidney injury (AKI) requiring continuous renal replacement therapy (CRRT). A total of 483 patients who received CRRT for AKI were selected and divided into three groups according to their serum chloride concentrations at the time of CRRT initiation. At 90 days after initiating CRRT, renal outcome, i.e., non-complete renal recovery, or renal failure, was assessed in the three groups. The hypochloremia group (serum chloride concentrations < 96 mEq/L, n = 60), the normochloremia group (serum chloride concentrations, 96–111 mEq/L, n = 345), and the hyperchloremia group (serum chloride concentrations > 111 mEq/L, n = 78) were classified. The simplified acute physiology score III was higher in the hyperchloremia and hypochloremia groups than in the normochloremia group. Multivariate logistic regression analyses showed that hypochloremia (odds ratio, 5.12; 95% confidence interval [CI], 2.56–10.23; P < 0.001) and hyperchloremia (odds ratio, 2.53; 95% CI, 1.25–5.13; P = 0.01) were significantly associated with non-complete renal recovery. Similar trends were observed for renal failure. This study showed that dyschloremia was independently associated with failure in restoring renal function following AKI.

ObjectiveObstruction release from urolithiasis can be delayed with a lack of suggested time for preventing the deterioration of renal function. The objective of this study was to investigate the effect of obstruction duration, concomitant acute kidney injury (AKI) or acute pyelonephritis (APN) during the obstruction on the prognosis of renal function.DesignRetrospective cohort study.Setting and participants1607 patients from a urolithiasis-related obstructive uropathy cohort, between January 2005 and December 2015.Outcome measuresEstimated glomerular filtration rate (eGFR) decrease ≥30% and/or end-stage renal disease (ESRD), and eGFR decrease ≥50% and/or ESRD, according to obstruction duration, AKI and APN accompanied by obstructive uropathy.ResultsWhen the prognosis was divided by obstruction duration quartile, the longer the obstruction duration the higher the probability of eGFR reduction >50% (p=0.02). In patients with concomitant APN or severe AKI during hospitalisation with obstructive uropathy, an eGFR decrease of >30% and >50% occurred more frequently, compared with others (p<0.001). When we adjusted for sex, age, hypertension, diabetes mellitus, APN, AKI grades and obstruction release >7 days for multivariate analysis, we found that concomitant APN (HR 3.495, 95% CI 1.942 to 6.289, p<0.001), concomitant AKI (HR 3.284, 95% CI 1.354 to 7.965, p=0.009 for AKI stage II; HR 6.425, 95% CI 2.599 to 15.881, p<0.001 for AKI stage III) and an obstruction duration >7 days (HR 1.854, 95% CI 1.095 to 3.140, p=0.001) were independently associated with an eGFR decrease >50%. Tree analysis also showed that AKI grade 3, APN and an obstruction duration >7 days were the most important factors affecting renal outcome.ConclusionsIn patients with urolithiasis-related obstructive uropathy, concomitant APN was strongly associated with deterioration of renal function after obstruction release. The elapsed time to release the obstruction also affected renal function.

Rapid Decrease

Acute renal failure (also referred to as acute kidney injury) refers to a rapid decrease in renal function; it is reflected by an increase in blood urea and creatinine and is often associated with oliguria (a urine volume of less than 400 ml/24 hours). It usually develops over days to weeks. Acute kidney injury has been variously classified, but the current classifications are based on the glomerular filtration rate (or creatinine), looking at changes from baseline, and the presence of oliguria or anuria. The potential etiologies of acute kidney injury are usually considered anatomically under the headings prerenal, renal (intrinsic), and postrenal. This chapter looks at the etiology, symptoms, clinical features, demographics, complications, diagnosis, and treatment of acute kidney injury.

Abstract BACKGROUND Acute kidney injury (AKI) occurs in many critically ill patients and is associated with high mortality. We examined whether proenkephalin could predict incident AKI and its improvement in septic patients. METHODS Plasma proenkephalin A 119–159 (penKid) was assayed in 956 patients with sepsis or septic shock enrolled in the multicenter Albumin Italian Outcome Sepsis (ALBIOS) trial to test its association with incident AKI, improvement of renal function, need for renal replacement therapy (RRT), and mortality. RESULTS Median [Q1–Q3] plasma penKid concentration on day 1 [84 (20–159) pmol/L[ was correlated with serum creatinine concentration (r = 0.74); it was higher in patients with chronic renal failure and rose progressively with the renal Sequential Organ Failure Assessment subscore. It predicted incident AKI within 48 h (adjusted odds ratio, 3.3; 95% CI, 2.1–5.1; P < 0.0001) or 1 week [adjusted hazard ratio, 2.1 (1.7–2.8); P < 0.0001] and future RRT during the intensive care unit stay [odds ratio, 4.0 (3.0–5.4)]. PenKid was also associated with improvements in renal function in patients with baseline serum creatinine >2 mg/dL, both within the next 48 h [adjusted odds ratio, 0.31 (0.18–0.54), P < 0.0001] and 1 week [0.23 (0.12–0.45)]. The time course of penKid concentrations predicted AKI and 90-day mortality. CONCLUSIONS Early measurement and the trajectory of penKid predict incident AKI, improvement of renal function, and the need for RRT in the acute phase after intensive care unit admission during sepsis or septic shock. PenKid measurement may be a valuable tool to test early therapies aimed at preventing the risk of AKI in sepsis.

Abstract Background and Aims Renal function recovery after acute kidney injury (AKI) is associated with patient outcomes. The study objectives were to assess the patterns of AKI recovery within 6 months following discharge for AKI and subsequent incidence of chronic dialysis. Method A retrospective cohort of 234,867 hospitalized adult patients was examined for AKI between January 1, 2010, and December 31, 2017 in the largest healthcare delivery system in Taiwan. Renal function recovery at 3- and 6-month post discharge, incident chronic kidney disease and chronic dialysis initiation were analyzed over 7 years of follow-up. Renal recovery was defined by < 1.5× baseline SCr (prior to the hospitalization). Independent associations between renal function recovery patterns and renal outcomes was assessed by Cox proportional hazard model controlling for potential confounders, and subdistribution hazard ratio (SHR) with [95% CI] was analysed for competing risk of early death. Results Among 3 months AKI survivors (n=24,132), 14.28% (n=3,430) did not recovery back to baseline, and 16% of recovery did not sustain. Three distinct renal function recovery continuums at 6 months post hospital discharge were: persistent non-recovery (10.18%), non-recovery (14.33%), and recovery (75.5%). Comparing to survivors without AKI (n=50,387), the impact of renal recovery continuum on chronic dialysis initiation varied by patient’s baseline renal disease (SHR was 2.82 [95%CI, 2.42-3.28] in CKD, and 0.8 [95%CI, 0.27-2.38] for non-CKD. Persistent non-recovery was significantly associated with a greater increased risk of chronic dialysis than non-recovery in any patients with AKI. Comparing to patients with sustained AKI recovery, risk of CKD onset increased 5-fold in persistent non-recovery and 3-fold risk in non-recovery. Conclusion The continuum of AKI recovery post 6 months is associated with increased risk of chronic dialysis, particularly in patients with baseline CKD. These study results suggested that patients ever with AKI should receive close renal function monitoring for post-discharge management.

The Difference

Exposure to dyschloremia among critically ill patients is associated with an increased risk of acute kidney injury (AKI). We aimed to investigate how fluctuations in serum chloride (Cl−) are associated with the development of AKI in critically ill patients. We retrospectively analyzed medical records of adult patients admitted to the intensive care unit (ICU) between January 2012 and December 2017. Positive and negative fluctuations in Cl− were defined as the difference between the baseline Cl- and maximum Cl- levels and the difference between the baseline Cl− and minimum Cl− levels measured within 72 h after ICU admission, respectively. In total, 19,707 patients were included. The odds of developing AKI increased 1.06-fold for every 1 mmol L−1 increase in the positive fluctuations in Cl− (odds ratio: 1.06; 95% confidence interval: 1.04 to 1.08; p < 0.001) and 1.04-fold for every 1 mmol L−1 increase in the negative fluctuations in Cl− (odds ratio: 1.04; 95% confidence interval: 1.02 to 1.06; p < 0.001). Increases in both the positive and negative fluctuations in Cl- after ICU admission were associated with an increased risk of AKI. Furthermore, these associations differed based on the functional status of the kidneys at ICU admission or postoperative ICU admission.

Abstract Background and Aims Acute kidney injury (AKI) is a complex disorder that occurs in several clinical settings. During pregnancy, there are additional unique conditions that contribute to AKI. The clinical manifestations of Pregnancy related acute kidney injury(PRAKI) range from a minimal elevation in serum creatinine to severe renal failure requiring renal replacement therapy and may be associated with significant morbidity and mortality in young healthy women. This study aims to describe epidemiologic features, study clinical profile and outcomes of women with PRAKI and identify risk factors related to requiring hemodialysis among patients. Method We performed a retrospective study over a 5-year period (2015–2019) in a Tunisian intensive care unit. All patients presenting PRAKI were included. Results Ninety-six cases of PRAKI were listed. The rate of AKI during pregnancy-related hospitalizations was 16% .the average age was 31 ± 5 years. Most women were from urban areas (62%) but with insufficient prenatal care (57%).Seventy-eight percent underwent cesarean section delivery. PRAKI occurred in the postpartum in 79%of the cases. Oligo-anuria was the most common clinical feature of PRAKI, noted in 82% of our patients. The leading etiological causes were pre eclampsia, eclampsia, postpartum haemorrhage and sepsis respectively, in 49%, 38%, and 24% of the cases. Hemodialysis was required in 23% of cases. In the adjusted regression analysis, factors associated with dialysis were insufficient prenatal care (p=0,010 ; O Ra=24,113), HELLP syndrome (p=0,003 ; ORa=35,129), disseminated intravascular coagulation (p=0,007 ; OR=11,854), average duration of oliguria (p=0,001; ORa=3,025) , Failure stage of RIFLE criteria while admitted (p=0,009; ORa=2,09) and length of ICU stay (p=0,042 ; ORa=1,118). Renal outcome was favorable, with a complete renal function recovery for 72 patients (75%). Only four patients (4%) developed chronic renal failure. Mortality rate was 13%. Conclusion PRAKI is a dreaded complication of pregnancy with high morbidity and mortality. Prevention of PRAKI requires an improvement of the sanitary infrastructures with the implementation of an obligatory prenatal consultation in order to prompt management of the underlying risk factors

Abstract Background and Aims Acute Kidney Injury (AKI) is an important determinant of outcome in hospitalized patients. Further, there is a risk for development of Chronic Kidney Disease (CKD) in the future. Though the long-term impact of AKI has been studied in developed countries, there is a paucity of data in this area from the Indian subcontinent. This single-centre study aimed to assess the pattern, clinical spectrum, short-term and long-term outcomes of AKI. Method In this prospective observational cohort study, detailed demographic and clinical data at presentation, during hospital stay and follow-up at 1, 3, 6 and 12 months after discharge were obtained prospectively for a cohort of patients with AKI. Both community (CAAKI) and hospital acquired AKI (HAAKI) were included. Patient with pre-existing CKD were excluded. Outcome variables examined were in-hospital mortality, renal function at discharge and on follow-up after discharge from hospital. Results In our study cohort with 476 patients, majority of the cases were CAAKI (395, 83%). The mean age at presentation was 44.8 ± 18.7 years. Medical causes (84%) contributed to the majority of AKI while the remaining were due to surgical (10%) and obstetrical (6%) causes. Sepsis (176/476; 36.9%) was the most common cause of AKI. The most common source for sepsis was respiratory (41%) followed by urological source (18.7%). The in-hospital mortality rate for patients with AKI was 38%. Age >60 years (HR = 1.51; 95% CI, 1.11 – 2.07), oliguria (HR = 1.48; 95% CI, 1.05 – 2.10), need for ventilator (HR = 2.45; 95% CI, 1.36 – 4.41) and/or inotropes (HR = 14.4; 95% CI, 6.28 – 33.05) were predictors of mortality. At discharge, 146 (30.7%) patients had complete renal recovery, while 149 (31.3%) had partial renal recovery. Oliguria (p < 0.001), hypoalbuminemia (p = 0.001) and need for renal replacement therapy (RRT) (p = 0.01) were significantly associated with partial recovery. Of the 295 patients on follow-up at discharge, 211 (71.5%) patients had normal renal function, 4 (1.4%) died and 33 (11.2%) were lost to follow up; 47(15.9%) patients developed CKD of which 6 (2%) were dialysis dependent. Elderly patients, higher AKIN stage with oliguria and those requiring RRT were more likely to develop CKD. Among these, the need for in-hospital RRT was the single most important factor predicting the risk of CKD (OR 1.77, 95% CI, 1.12-2.78). Conclusion In conclusion, our data shows that AKI in hospitalized patients still has high mortality in emerging countries like India. Though a fairly good percentage of cases recovered, there is a definite risk of CKD development, especially in patients who required RRT during hospitalization.

Abstract Background Acute kidney injury (AKI) is common in patients in the intensive care unit (ICU) and may be present on admission or develop during ICU stay. Our objectives were (a) to identify factors independently associated with the development of new AKI during early stay in the ICU and (b) to determine the risk factors for non-recovery of AKI. Methods We retrospectively analysed prospectively collected data of patients admitted to a multi-disciplinary ICU in a single tertiary care centre in the UK between January 2014 and December 2016. We identified all patients without AKI or end-stage renal failure on admission to the ICU and compared the outcome and characteristics of patients who developed AKI according to KDIGO criteria after 24 h in the ICU with those who did not develop AKI in the first 7 days in the ICU. Multivariable logistic regression was applied to identify factors associated with the development of new AKI during the 24–72-h period after admission. Among the patients with new AKI, we identified those with full, partial or no renal recovery and assessed factors associated with non-recovery. Results Among 2525 patients without AKI on admission, the incidence of early ICU-acquired AKI was 33.2% (AKI I 41.2%, AKI II 35%, AKI III 23.4%). Body mass index, Sequential Organ Failure Assessment score on admission, chronic kidney disease (CKD) and cumulative fluid balance (FB) were independently associated with the new development of AKI. By day 7, 69% had fully recovered renal function, 8% had partial recovery and 23% had no renal recovery. Hospital mortality was significantly higher in those without renal recovery. Mechanical ventilation, diuretic use, AKI stage III, CKD, net FB on first day of AKI and cumulative FB 48 h later were independently associated with non-recovery with cumulative fluid balance having a U-shape association. Conclusions Early development of AKI in the ICU is common and mortality is highest in patients who do not recover renal function. Extreme negative and positive FB were strong risk factors for AKI non-recovery.
