Serum estradiol levels predict survival and acute kidney injury in patients with septic shock--a prospective study.

ABSTRACT: Sex hormones have diverse immunomodulatory effects that may be involved in the pathogenesis of sepsis. However, the roles of serum sex hormones in predicting outcomes and the severity of organ dysfunction, especially acute kidney injury (AKI), in septic shock patients remains controversial. We prospectively enrolled 107 clinically diagnosed pneumonia-related septic shock patients and serum sex hormone levels were measured on the day of shock onset. The aim of the present study was to investigate the predictive values of serum sex hormones levels for 28-day mortality and organs dysfunction, especially AKI. Compared with survivors, serum levels of progesterone (p<0.001) and estradiol (p<0.001) were significantly elevated in non-survivors. In multivariate Cox regression analysis, serum level of estradiol >40 pg/mL (p?=?0.047) and APACHE II score ?25 (p?=?<0.001) were found to be independent predictors of day 28 mortality. Inclusion of estradiol levels further enhanced the ability of APACHE II scores to predict survival in patients with high mortality risk. A serum level of estradiol >40 pg/mL was also an independent predictor of concomitant AKI (p?=?0.002) and correlated well with severity of renal dysfunction using RIFLE classification. Elevated serum estradiol levels also predicted the development of new AKI within 28 days of shock onset (p?=?0.013). In conclusion, serum estradiol levels appear to have value in predicting 28-day mortality in septic shock patients. Increased serum estradiol levels are associated with higher severity of concomitant AKI and predict development of new AKI.

Project description:Acute kidney injury (AKI) after cardiac surgery is a common and serious complication. Although lower than normal serum bicarbonate levels are known to be associated with consecutive renal function deterioration in patients with chronic kidney injury, it is not well-known whether preoperative low serum bicarbonate levels are associated with the development of AKI in patients who undergo cardiac surgery. Therefore, the clinical implication of preoperative serum bicarbonate levels on AKI occurrence after cardiac surgery was investigated. Patients who underwent coronary artery bypass or valve surgery at Yonsei University Health System from January 2013 to December 2014 were enrolled. The patients were divided into 3 groups based on preoperative serum bicarbonate levels, which represented group 1 (below normal levels) <23?mEq/L; group 2 (normal levels) 23 to 24?mEq/L; and group 3 (elevated levels) >24?mEq/L. The primary outcome was the predicated incidence of AKI 48?hours after cardiac surgery. AKI was defined according to Acute Kidney Injury Network criteria. Among 875 patients, 228 (26.1%) developed AKI within 48?hours after cardiac surgery. The incidence of AKI was higher in group 1 (40.9%) than in group 2 (26.5%) and group 3 (19.5%) (P?<?0.001). In addition, the duration of postoperative stay in a hospital intensive care unit (ICU) was longer for AKI patients and for those in the low-preoperative-serum-bicarbonate-level groups. A multivariate logistic regression analysis showed that low preoperative serum bicarbonate levels were significantly associated with AKI even after adjustment for age, sex, hypertension, diabetes mellitus, operation type, preoperative hemoglobin, and estimated glomerular filtration rate. In conclusion, low serum bicarbonate levels were associated with higher incidence of AKI and prolonged ICU stay. Further studies are needed to clarify whether strict correction of bicarbonate levels close to normal limits may have a protective role in preventing further AKI development.

Project description:Adults hospitalized with sepsis/septic shock commonly develop acute kidney injury (AKI) which imposes a significant burden on the healthcare system. The administration of early human albumin in this patient population may yield more efficient healthcare resource utilization.ObjectivesTo examine the association between early use of albumin and time to discharge in adults who develop severe AKI while hospitalized with sepsis/septic shock.DesignRetrospective cohort study using de-identified electronic health records from a national database (Cerner Health Facts; Cerner Corp., Kansas City, MO).Setting and participantsPatients (n = 2,829) hospitalized between January 2013 and April 2018 with a diagnosis of sepsis/septic shock (identified using International Classification of Diseases, 9th Revision and 10th Revision codes) who developed severe AKI (stage 3 according to Kidney Disease Improving Global Outcomes criteria) during hospitalization (n = 2,845 unique encounters).Main outcomes and measuresPatients were grouped according to timing of albumin exposure: within less than or equal to 24 hours of admission ("early albumin") or unexposed/exposed late ("nonearly albumin"). A cause-specific hazard model, censoring for death/discharge to hospice, was used to examine the association between "early albumin" and the rate of hospital discharge with clinical stability.ResultsAlbumin was administered early in 8.6% of cases. Cases with early albumin administration had a median time to discharge of 13.2 days compared with 17.0 in the nonearly group (Log-rank p < 0.0001). An adjusted analysis showed that the rate of hospital discharge with clinical stability increased by 83% in the early albumin group compared with the nonearly group (hazard ratio, 1.832; 95% CI, 1.564-2.146; p < 0.001 nonearly group.Conclusions and relevanceThe use of albumin within 24 hours of hospital admission was associated with a shorter time to discharge and a higher rate of discharge with clinical stability, suggesting an improvement in healthcare resource utilization among patients with sepsis/septic shock who developed stage 3 AKI during hospitalization.

Project description:BackgroundHaemoadsorption has been described as an effective way to control increased pro- and anti-inflammatory mediators ("cytokine storm") in septic shock patients. No prospective or randomised clinical study has yet confirmed these results. However, no study has yet prospectively specifically investigated patients in severe septic shock with sepsis-associated acute kidney injury (SA-AKI). Therefore, we aimed to examine whether haemoadsorption could influence intensive care unit (ICU) and hospital mortality in these patients. Furthermore, we examined the influence of haemoadsorption on length of stay in the ICU and therapeutic support.MethodsRetrospective control group and prospective intervention group design in a tertiary hospital in central Europe (Germany). Intervention was the implementation of haemoadsorption for patients in septic shock with SA-AKI. 76 patients were included in this analysis.ResultsSeverity of illness as depicted by APACHE II was higher in patients treated with haemoadsorption. Risk-adjusted ICU mortality rates (O/E ratios) did not differ significantly between the groups (0.80 vs. 0.83). We observed in patients treated with haemoadsorption a shorter LOS and shorter therapeutic support such as catecholamine dependency and duration of RRT. However, in multivariate analysis (logistic regression for mortality, competing risk for LOS), we found no significant differences between the two groups.ConclusionsThe implementation of haemoadsorption for patients in septic shock with acute renal failure did not lead to a reduction in ICU or hospital mortality rates. Despite univariate analysis delivering some evidence for a shorter duration of ICU-related treatments in the haemoadsorption group, these results did not remain significant in multivariate analysis.

Project description:IntroductionDespite recent advances in the management of septic shock, mortality rates are still unacceptably high. Early identification of the high-mortality risk group for early intervention remains an issue under exploration. Vascular endothelial growth factor (VEGF), soluble vascular endothelial growth factor receptor-1 (sVEGFR1) and urokinase plasminogen activator (uPA) have diverse effects in the pathogenesis of sepsis, which involve pro-inflammation, anti-inflammation, endothelial cell repair, and vascular permeability change. Their roles in predicting mortality and organ dysfunction remain to be clarified.MethodsPneumonia-related septic shock patients from medical intensive care units were enrolled for this prospective observational study. We also included 20 patients with pneumonia without organ dysfunction for comparison. Plasma levels of VEGF and sVEGFR1 and uPA activity within 24 hours of shock onset were measured. We compared plasma levels of these biomarkers with APACHE II scores between subgroups of patients, and evaluated their predictive value for 28-day mortality and organ dysfunction.ResultsA total of 101 patients, including 81 with pneumonia-related septic shock and 20 with pneumonia without organ dysfunction, were enrolled. Non-survivors of septic shock had significantly higher plasma sVEGFR1 levels (659.3 ± 1022.8 vs. 221.1 ± 268.9 pg/mL, respectively, P < 0.001) and uPA activity (47.2 ± 40.6 vs. 27.6 ± 17.2 units, respectively, P = 0.001) when compared with those of the survivors. Kaplan-Meier survival analysis demonstrated significantly higher mortality in patients with higher levels of sVEGFR1 (P < 0.001) and uPA activity (P = 0.031). In Cox regression analysis, plasma sVEGFR1 level was independently associated with, and best predicted, the 28-day mortality of septic shock (HR: 1.55, 95% CI: 1.05-2.30). Plasma sVEGFR1 level and uPA activity had good correlation with renal dysfunction, metabolic acidosis, and hematologic dysfunction; their levels significantly increased when the number of organ dysfunctions increased. In multivariate analysis, plasma sVEGFR1 level (HR: 2.82, 95% CI: 1.17-6.81) and uPA activity (HR: 2.75, 95% CI: 1.06-7.13) were independent predictors of the presence of concomitant multi-organ dysfunction. The predictive value of VEGF for mortality and organ dysfunction was limited in pneumonia-related septic shock patients.ConclusionsHigh plasma sVEGFR1 level in the early stage of pneumonia-related septic shock independently predicted 28-day mortality and multi-organ dysfunction.
