Two-year follow-up of patients with septic shock presenting with low HDL: the effect upon acute kidney injury, death and estimated glomerular filtration rate

AbstractIntroduction:There are little data about renal follow-up of neonates after cardiovascular surgery and no guidelines for long-term renal follow-up. Our objectives were to assess renal function follow-up practice after neonatal cardiac surgery, evaluate factors that predict follow-up serum creatinine measurements including acute kidney injury following surgery, and evaluate the estimated glomerular filtration rate during follow-up using routinely collected laboratory values.Methods:Two-centre retrospective cohort study of children 5–7 years of age with a history of neonatal cardiac surgery. Univariable and multivariable analyses were performed to determine factors associated with post-discharge creatinine measurements. Glomerular filtration rate was estimated for each creatinine using a height-independent equation.Results:Seventeen of 55 children (30%) did not have any creatinine measured following discharge after surgery until the end of study follow-up, which occurred at a median time of 6 years after discharge. Of the 38 children who had the kidney function checked, 15 (40%) had all of their creatinine drawn only in the context of a hospitalisation or emergency department visit. Acute kidney injury following surgery did not predict the presence of follow-up creatinine measurements.Conclusions:A large proportion of neonates undergoing congenital heart repair did not have a follow-up creatinine measured in the first years following surgery. In those that did have a creatinine measured, there did not appear to be any identified pattern of follow-up. A follow-up system for children who are discharged from cardiac surgery is needed to identify children with or at risk of chronic kidney disease.

Background. Severe acute kidney injury (AKI) among hospitalized patients often necessitates initiation of short-term dialysis. Little is known about the long-term outcome of those who recover to normal renal function. The aim of this study was to determine the long-term renal outcome of patients experiencing AKI requiring dialysis secondary to hypoperfusion injury and/or sepsis who recovered to apparently normal renal function. Methods. All adult patients with AKI requiring dialysis in our centre between 1 January 1980 and 31 December 2010 were identified. We included patients who had estimated glomerular filtration rate (eGFR) >60 mL/min/1.73 m2 12 months or later after the episode of AKI. Patients were followed up until 3 March 2015. The primary outcome was time to chronic kidney disease (CKD) (defined as eGFR persistently <60 mL/min/1.73 m2) from first dialysis for AKI. Results. Among 2922 patients with a single episode of dialysis-requiring AKI, 396 patients met the study inclusion criteria. The mean age was 49.8 (standard deviation 16.5) years and median follow-up was 7.9 [interquartile range (IQR) 4.8–12.7] years. Thirty-five (8.8%) of the patients ultimately developed CKD after a median of 5.3 (IQR 2.8–8.0) years from first dialysis for AKI giving an incidence rate of 1 per 100 person-years. Increasing age, diabetes and vascular disease were associated with higher risk of progression to CKD [adjusted hazard ratios (95% confidence interval): 1.06 (1.03, 1.09), 3.05 (1.41, 6.57) and 3.56 (1.80, 7.03), respectively]. Conclusions. Recovery from AKI necessitating in-hospital dialysis was associated with a very low risk of progression to CKD. Most of the patients who progressed to CKD had concurrent medical conditions meriting monitoring of renal function. Therefore, it seems unlikely that regular follow-up of renal function is beneficial in patients who recover to eGFR >60 mL/min/1.73 m2 by 12 months after an episode of AKI.
