Abstract Abstract 2215 Introduction: Among survivors of TTP associated with severe ADAMTS13 deficiency, long-term outcomes other than relapse are not well documented. The recent report of persistent minor neurocognitive abnormalities attributed to subcortical microvascular thrombosis (Transfusion 2009;49:1092) suggested that other organs may also be affected by subclinical abnormalities. Therefore we documented renal function in patients in the Oklahoma TTP-HUS Registry who survived acute episodes of TTP associated with severe ADAMTS13 deficiency (activity <10%). Methods: ADAMTS13 activity has been measured in 299 of 321 (93%) patients, 1995–2010. Glomerular filtration rate (GFR) was calculated by the Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) equation (Ann Int Med 2009;150:604). Urine protein was measured by dipstick. Patient GFRs were compared to GFRs for the US population using data from the National Health and Nutrition Examination Survey (NHANES), 1998–2006, that had been analyzed in the CKD-EPI study. Results: 68 of 299 (23%) patients from the Oklahoma TTP-HUS Registry had severe ADAMTS13 deficiency. Fifty-five of the 68 (81%) patients with severe ADAMTS13 deficiency survived their initial episode of TTP. Among the 55 survivors, 48 (87%) have had ≥1 year of follow-up (median, 6.4 years; range, 1.0 – 14.9 years). The 7 patients whose follow-up was less than 1 year included 3 patients whose initial episode was within the past year; 2 with systemic lupus erythematosus who died within one year; 1 who relapsed and died at one year; 1 lost to follow-up. Sixteen (33%) of the 48 patients had 1–4 relapses. None of the 48 patients developed end stage renal disease and none developed severe chronic kidney disease (GFR <30 ml/min/1.73m2). Three of the 48 patients had chronic kidney disease with moderately decreased GFR (GFR 30–59 ml/min/1.73m2); two of these patients had hypertension and one had hypertension and diabetes prior to their initial episodes of TTP. The median GFR was 97 ml/min/1.73m2 (range, 30 – 139 ml/min/1.73m2). The GFR for the ADAMTS13 deficient TTP patients was not different from the GFR of the U.S. population (p=0.289) (Figure 1). Urine protein was measured on 34 patients (median follow-up, 6.7 years; range, 1.2–14.9 years): 32 (94%) were negative; 2 (6%) were trace, equivalent to <30 μg albumin/mg creatinine. Conclusion: Renal function of TTP patients with severe ADAMTS13 deficiency who had been followed for a median of 6.4 years following recovery from their initial episode was not different from the US population. Disclosures: No relevant conflicts of interest to declare.

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.

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.

Lipid Spectrum

Background. In patients after liver transplantation cardiovascular complications is the third main reason of death afer allograf failure and infections. The most important factors in the development of cardiovascular diseases are dyslipidemia and impaired renal function. The aim of the study was to investigate the lipid spectrum and renal function in liver recipients in real clinical practice and the correspondence of their correction to current clinical recommendations for the diagnosis and treatment of dyslipidemia and chronic kidney disease (CKD). Methods. A retrospective analysis of lipid spectrum and renal function in patients who underwent OLT in Research Institute – Regional Clinical Hospital №1, Krasnodar was performed. The level of creatinine, GFR and lipid spectrum was studied before and 36 months after liver transplantation. The GFR was calculated using the formula CKD‑EPI (Chronic Kidney Disease Epidemiology Collaboration). Statistical analysis of the study results was made using the program Statistica 10. Results. Liver recipients have a significantly higher total cholesterol by 31.0% (p<0.01) in comparison with the baseline before surgery. Total cholesterol was increased in 13.7% (p<0.01), triglycerides in 12.3% (p<0.01) before transplantation. Tree years after transplantation, the increasion in cholesterol was registered in 42.6% (p<0.01) and triglycerides in 37.9% (p <0.01), respectively. 3 years after transplantation reduction of GFR was observed in comparison with the baseline by 22.6% (p=0.00006). Verification of chronic kidney disease and statin administration in patients were carried out in some cases. The levels of total cholesterol and triglycerides had a reliable inverse correlation with GFR (r = ‑0.42; p<0.01 and r = ‑0.36; p<0.05). Conclusions. In the long‑term postoperative period there was an impaired lipid metabolism and decreased level of GFR. Dyslipidemia was closely related to the progression of renal dysfunction in liver recipients, an inverse correlation was established between the glomerular filtration rate and the increasion in cholesterol and triglyceride levels. It is necessary to increase the attention of physicians with regard to timely correction of lipid metabolism disorders and detection of initial manifestations of renal dysfunction.

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.

Background: Chronic kidney disease (CKD) is a condition presenting with long-term slow progression of structural and/or functional damage to the kidneys. Early detection is key to preventing complications and improving outcomes. Point-of-care estimated glomerular filtration rate (eGFR) screening technology allows for detection of abnormal kidney function in the community pharmacy setting. Objective: To evaluate the effectiveness of a community pharmacist-directed point-of-care screening program and to identify the prevalence of CKD in high-risk patients. Design: Quantitative observational. Setting: Four community pharmacies in British Columbia over a 6-month period. Patients: In all, 642 participants with at least one CKD risk factor were identified and screened. Mean age was 60 years and females accounted for 55% of the study population. Measurements: Serum creatinine was measured from peripheral blood using the HeathTab® screening system (Piccolo® Renal Function Panel with the Piccolo® blood chemistry analyzer). eGFR was calculated according to the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. Methods: Patients provided a sample of peripheral blood via a self-administered finger-prick and analytical data to assess kidney function was reported including blood urea nitrogen (BUN), serum creatinine, and electrolytes by the HealthTab® screening system. Once results were available, the pharmacist conducted a comprehensive medication review with the patient and recommended certain follow-up actions if appropriate. Results: CKD risk factor included diabetes (30%), hypertension (45%), cardiovascular disease (12%), family history of kidney disease (13%), age over 55 years (68%), and an Aboriginal, Asian, South Asian, or African ethnic background (82%). A total of 11.5% of patients had eGFR values lower than 60 mL/min (abnormal renal function) and 34% had an eGFR between 60 and 89 mL/min (minimally reduced renal function). Overall pharmacists’ actions included blood pressure check (98%), education on CKD and risk factors (89%), medication review (72%), and physician follow-up (38%). Limitations included lack of follow-up beyond the 3-month study period prevented medical confirmation of CKD and limited the ability to quantify the impact of pharmacist interventions on the clinical outcomes of patients with low eGFR. Conclusion: These results illustrate the prevalence of abnormal renal function among undiagnosed, high-risk patients in the community. Pharmacists, as the most accessible healthcare practitioners, are ideally positioned to utilize novel point-of care technologies to improve access to CKD screening, facilitate follow-up, and increase awareness around the importance of early detection.

Background Bariatric surgery (BS) might be a nephroprotective treatment in obese patients with chronic kidney disease (CKD), and the non-linear relation between body surface area (BSA) and extracellular fluid volume (ECFV) in obese people raises the question of the most relevant way to scale glomerular filtration rate (GFR) for assessing renal function changes after BS. Methods We screened 1774 BS candidates and analysed 10 consecutive participants with CKD stage 3. True GFR (mGFR), measured by the renal clearance of 51Cr-ethylenediaminetetraacetic acid (EDTA), was scaled either to BSA (mGFRBSA) or to ECFV measured by 51Cr-EDTA distribution volume (mGFRECFV) before and one year after BS. Results The 10 candidates for BS had a mean body mass index of 43.3 ± 3.6 kg/m2 and a mean GFR of 48 ± 8 mL/min/1.73 m2. Six participants had a sleeve gastrectomy and four had a Roux-en-Y gastric bypass. One year after BS, ECFV decreased (23.2 ± 6.2 to 17.9 ± 4.3 L, p = 0.001), absolute mGFR was not significantly modified (74 ± 23 versus 68 ±19 mL/min), mGFRBSA did not change significantly (53 ± 18 versus 56 ± 17 mL/min/1.73 m2) whereas mGFRECFV significantly increased (42 ± 13 versus 50 ± 14 mL/min/12.9 L, p = 0.037). The relation between mGFRECFV and mGFRBSA was different from the identity line before (p = 0.014) but not after BS (p = 0.09). Conclusion There is a difference between mGFRBSA and mGFRECFV following BS and the latter might better reflect the adequacy between renal function and corpulence.

Resistant hypertension and chronic kidney disease are closely related from a pathogenetic and clinical point of view. To study the dynamics of functional state of kidneys and as well as to identify the predictors of its improvement, 117 patients with resistant hypertension were examined. Dynamic follow−up of patients included monitoring of antihypertensive therapy, blood pressure, biochemical and humoral parameters during 3, 6 and 36 months of treatment. The findings have shown that a significant long−term improvement in blood pressure control in the patients with chronic kidney disease improves their function and also has a nephroprotective effect in patients without any signs of renal damage. The established prognostic value of the higher initial creatinine content for the improvement of renal function in patients with resistant hypertension is stipulated with a positive effect of antihypertensive therapy on the glomerular filtration rate dynamics. The close association between improved renal function and lower baseline levels of interleukin 6 as well as an active renin in the blood may indicate a role for systemic inflammation and renin−angiotensin−aldosterone system activity in the renal dysfunction development. Prolonged improvement in blood pressure control in the patients with resistant hypertension without diabetes is associated with a stable level of urinary albumin excretion, whereas in patients with diabetes, an albuminuria increases over time. The study concluded that independent predictors of improved renal function in patients with resistant hypertension are higher baseline creatinine and lower glomerular filtration rate, lower concentrations of interleukin 6, active renin and plasma potassium. Key words: resistant arterial hypertension, chronic kidney disease, functional state of kidneys, antihypertensive therapy.
