Function Measurement

Accurate measurement of renal function in serious liver disease is very important not only for the estimation of renal damage (chronic kidney disease – CKD), safe drug management, prediction of illness follow-up, intensive methods including hemodialysis, hemodiafiltration or hemoperfusion, but also for the indication of liver transplantation. All methods of renal function measurement using serum creatinine for the estimation of glomerular filtration rate (GFR) are not accurate: they overestimate the value of GFR; the worse the liver damage is, the higher the level of overestimation; predominantly due to decreased endogenous creatinine production (creatinine generation rate – CGR). Using of cystatin C for GFR in liver disease is mainly promising in acute kidney injury (AKI), but obtained results have not been defi nitive yet and need more relevant data from diff erent methods of GFR estimation.

Abstract Background and Aims Acute kidney injury (AKI) is common in the elderly due to physiologic renal aging and underlying pathologies. Few studies focused on AKI in Tunisian elderly. The aim of our study was to highlight the epidemiological, clinical, etiological, therapeutic, and progressive characteristics of AKI in elderly. Method We conducted a descriptive retrospective study of AKI in patients admitted to our department over a period of 04 years from 01/01/2014 to 31/12/2017. Results We collected 40 patients including 25 women and 15 men with a sex ratio of 1.66. The mean age was 74 [65-87] years. We noted the presence of pre-existing chronic kidney disease in 58% of cases, diabetes in 50% of cases and hypertension in 73% of cases. Polypharmacy was found in 40% of cases. AKI was symptomatic in 80% of cases and found on a routine check-up in 20% of cases. Mean creatinine was 612+/-334 µmol/l. AKI was pre-renal in 37% and parenchymal in 63% of cases. Iatrogenic origin was found in 33% of cases. Renal biopsy was performed for diagnostic purposes in 6 cases. Haemodialysis was necessary in 50% of cases. Etiopathogenic treatment was initiated in 73% of cases. Intra-hospital mortality was 10%, recovery of renal function (RF) was partial in 40 % of cases and total in 20 % of cases. Follow-up time was 16 +/- 23.2 months. And at the last news, recovery of renal function (RF) was partial in 7 cases and total in 10 cases, 6 patients kept a chronic renal failure (CRF), among them 3 cases had and end-stage of CRF. Conclusion AKI is a frequent pathology in the elderly and its severity is linked to mortality and the transition to chronicity. Iatrogenic causes are frequent and preventable in this population, hence the major interest of prevention.

Calcineurin Inhibitors

Introduction. Chronic renal failure is a significant issue regarding treatment of patients after liver transplantation. One of the factors determining the impaired renal function after liver transplantation is a long-term immunosuppressive therapy based on calcineurin inhibitors. The objective of the study was to evaluate the dynamics of renal function, depending on the use of various calcineurin inhibitors in the long-term postoperative period in liver recipients in real clinical practice. Materials and methods. A retrospective analysis of the renal function in patients operated in the State Public Health Budget Institution “Scientific Research Institute – S.V. Ochapovsky Regional Clinic Hospital № 1”, Krasnodar Region, was carried out. This article describes dynamics of creatinine level and glomerular filtration rate (GFR) in patients before liver transplant, as well as 6 months, 1, 2 and 3 years after surgery. GFR was calculated using the CKD-EPI formula (Chronic Kidney Disease Epidemiology Collaboration). Statistical processing of the results was carried out using the Statistica 10 software package. Results and discussion. Before transplantation, the level of creatinine in the blood plasma was 82.9±19.8 mmol/l, 6 months later a20.4% increase in creatinine was registered (p=0.004), 12, 24 and 36 months later – it increased by 24.8% (p=0.00001), 24.4% (p=0.0004), and 26.0% (p=0.0005), respectively. Both cyclosporine and tacrolimus caused an increase in the level of creatinine. Baseline GFR was 83.4±25.9, the reduction in GFR occurred in comparison with the baseline by 14.2% (p=0.0005), 18.8% (p=0.00001), 20.2% (p=0.00003), 22.6% % (p=0.00006) 6, 12, 24 and 36 months later, respectively. The degree of the decrease in GFR against the background of tacrolimus therapy did not differ significantly from that in case of cyclosporine. Verification of chronic kidney disease and the administration of statins were recorded in isolated cases. Conclusions. In liver recipients, the level of creatinine rises and GFR decreases. Reduction of kidney function occurs against the background of both inhibitors of calcineurin, in connection with which it is necessary to increase the doctors’ alertness for early detection of a decrease in glomerular filtration rate with further verification of chronic kidney disease.

Risk Of Progression

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.

Background. Acute kidney injury (AKI) is a common complication of cardiac surgery but its long-term consequences, in patients with chronic kidney disease (CKD), are not known.Methods. We compared the long-term prognoses of CKD patients who developed (n=23) and did not develop (n=35) AKI during the period of hospitalization after undergoing coronary artery bypass graft (CABG). Fifty-eight patients who survived (69.6±8.4years old, 72% males, 83% Whites, 52% diabetics, baseline GFR:46±16 mL/min) were followed up for47.8±16.4months and treated for secondary prevention of events.Results. There were 6 deaths, 4 in the AKI+ and 2 in the AKI− group (Log-rank = 0.218), two attributed to CV causes. At the end of the study, renal function was similar in the two groups. One AKI− patient was started on dialysis. Only 4 patients had an increase in serum creatinine ≥ 0.5 mg/dL during follow-up.Conclusion. CKD patients developing AKI that survived the early perioperative period of coronary intervention present good renal and nonrenal long-term prognosis, compared to patients who did not develop AKI.

Atrial fibrillation (AF) is the most frequent type of supraventricular arrhythmias. The anticoagulant therapy should be prescribed to prevent thromboembolic events. According to randomized clinical trials, anticoagulants do not always prove their high efficiency in the real clinical practice. It is a complicated issue for any doctor to prescribe the anticoagulant therapy for patients with AF and CKD. 30 % of patients with atrial fibrillation are known to have chronic kidney disease, while 10-15% of patients with chronic kidney disease are diagnosed with atrial fibrillation. Currently, there are scarce studies into the use of direct oral anticoagulants in patients with atrial fibrillation and chronic kidney disease (in case of Glomerular Filtration Rate (GFR) below 45 ml/min/1.73 m2).Aim. To determine the dynamics of GFR in patients with AF and CKD (in case of GFR below 45 ml/min/1.73 m2).Material and Methods. The sub-analysis was carried out to examine a single-centre prospective study into the optimization of the anticoagulant therapy in the outpatient practice. Initially, 133 dabigatran taking patients were enrolled in the study, and 79 patients were included in the final analysis. Endpoints were changes in Glomerular Filtration Rate (CKD-EPI) formulae as of the inclusion date, in 6, 12, 24 and 60 months after the inclusion. Changes in the renal function shall mean a decrease or increase in GFR by ≥5 ml/min.Results. The average follow-up period for patients was 1785 ± 218 days. A GFR>45 ml/min/1.73 m2 occurred in 116 (87.2%) patients, and a GFR <45 ml/min/1.73 m2 was found in 17 (12.8%) patients. The average HAS-BLED score was 1.8, and CHA2DS2VASc score - 3.8. During the observation period, there were 3 cases of major bleeding and 133 cases of minor bleeding. Both major (р=0.025) and minor (р=0.012) bleeding were statistically significant more frequent in patients with GFR below 45 ml/min. During 5 years of follow-up, 66 (49.6%) patients had an average decrease in GFR of 3.32 ml/min/1.73 m2 per year. Patients with the initially declined GFR (below 45 ml/min) did not demonstrate a significant dynamic of the renal function during the dabigatran therapy. The mortality rate in this group during the observation period was 61.5%.Conclusion. In 49.6% of patients during 5 years of follow-up, GFR decreased by an average of 3.32 ml/min/1.73 m2 per year, which does not exceed the indicators typical for patients with cardiovascular events and CKD.

Abstract Purpose An increase in arterial stiffness is associated with rapid renal function decline (RFD) in patients with chronic kidney disease (CKD). The aim of this study was to investigate whether the radial augmentation index (rAI), a surrogate marker of arterial stiffness, affects RFD in individuals without CKD. Methods A total of 3165 Chinese participants from an atherosclerosis cohort with estimated glomerular filtration rates (eGFR) of ≥ 60 mL/min/1.73 m2 were included in this study. The baseline rAI normalized to a heart rate of 75 beats/min (rAIp75) was obtained using an arterial applanation tonometry probe. The eGFRs at both baseline and follow-up were calculated using the equation derived from the Chronic Kidney Disease Epidemiology Collaboration. The association of the rAIp75 with RFD (defined as a drop in the eGFR category accompanied by a ≥ 25% drop in eGFR from baseline or a sustained decline in eGFR of > 5 mL/min/1.73 m2/year) was evaluated using the multivariate regression model. Results During the 2.35-year follow-up, the incidence of RFD was 7.30%. The rAIp75 had no statistically independent association with RFD after adjustment for possible confounders (adjusted odds ratio = 1.12, 95% confidence interval: 0.99–1.27, p = 0.074). When stratified according to sex, the rAIp75 was significantly associated with RFD in women, but not in men (adjusted odds ratio and 95% confidence interval: 1.23[1.06–1.43], p = 0.007 for women, 0.94[0.76–1.16], p = 0.542 for men; p for interaction = 0.038). Conclusion The rAI might help screen for those at high risk of early rapid RFD in women without CKD.
