AbstrakRenogram 99mTc-DTPA (diethylenetriamine pentacetic acid) memiliki beberapa kelebihan dalam mengukur laju filtrasi glomerulus (LFG). Cystatin-c digunakan sebagai petanda biologik baru untuk memperkirakan LFG. Tujuan penelitian ini adalah untuk menentukan korelasi nilai LFG antara renogram dengan cystatin-c dan kliren kreatinin pada pasien dengan penyakit ginjal kronis (PGK). Subjek penelitian adalah pasien PGK stadium dua berdasarkan hasil estimasi LFG dengan rumus Cockroft-Gault. Pasien yang memenuhi kriteria diperiksa renogram, kadar kreatinin serum, cystatin-c dan klirens kreatinin.Rerata LFG dari 30 orang subjek yang diperiksa dengan renogram, cystatin-c, creatinine clearance, Cockroft-Gault’s formula berturut turut adalah 64.96 ml/min/1.73m2 (SD 28.047), 53.37 ml/min/1.73m2 (SD 21.29), 58.09 ml/min/1.73m2 (SD 35.45), 46.00 ml/min/1.73m2 (SD 12.06). Korelasi antara renogram dengan cystatin-c dengan nilai r = 0.585 dan p = 0.0007, antara renogram dengan klirens kreatinin dengan nilai r = 0.388 dan p = 0.03) dan antara renogram dengan rumus Cockroft-Gault’s dengan nilai r = -0.029 dan p=0.87. Pada penelitian ini didapatkan hasil korelasi yang lebih baik antara renogram dengan cystatin-c dari pada antara renogram dengan klirens kreatinin dan antara renogram dengan rumus Cockroft-Gault’s. Lebih lanjut, cystain-c merupakan alternatif yang lebih baik untuk memperkirakan LFG jika metode pemeriksaan LFG yang mendekati teknik pemeriksaan yang ideal tidak tersedia.AbstractRenogram using 99mTc-DTPA (diethylenetriamine pentacetic acid) has advantages in the measurement of glomerular filtration rate (GFR). Serum cystatin-c was recently projected to be the new marker of estimated GFR. The aim of this study is to establish correlation between GFRs, derived from renogram with cystatin-c levels and creatinine clearances in chronic kidney disease patients.We put to study thirty consecutive stage two of chronic kidney disease patients assigned based on GFR estimation by Cockroft-Gault’s formula, taking into account the serum creatinine. Cystatin-c and creatinine clearance were performed to determine of GFR and renogram was included in this study. A total of thirty subjects, the mean of GFRs were taken from renogram, cystatin-c, creatinine clearance, Cockroft-Gault’s formula were 64.96 ml/min/1.73m2 (SD 28.047), 53.37 ml/min/1.73m2 (SD 21.29), 58.09 ml/min/1.73m2 (SD 35.45), 46.00 ml/min/1.73m2 (SD 12.06) respectively. A correlation between renogram with cystatin-c (r = 0.585 and p = 0.0007) and renogram with creatinine clearance (r = 0.388 and p = 0.03) and renogram with Cockroft-Gault’s formula (r = -0.029 and p=0.87). This study has shown that a better correlation between renogram with cystatin-c than with creatinine clearance or Cockroft-Gault’s formula. Furthermore, cystain-c would be better alternative method incase having problems to obtain a closest ideal methods for GFR.

Adverse Outcomes

Background: Over/under-estimating renal function may increase inappropriate dosing strategy associated adverse outcomes; however, previously reported equations to estimate renal function have limited accuracy in chronic kidney disease (CKD) patients. Consequently, we intended to develop a novel equation to precisely estimate renal function and subsequently guide clinical treatment for CKD patients.Methods: A novel approach, Xiangya-s equation, to estimate renal function for CKD patients was derived by linear regression analysis and validated in 1885 patients with measured glomerular filtration rate (mGFR) < 60 ml/min/1.73 m2 by renal dynamic imaging at three representative hospitals in China, with the performance evaluated by accuracy, bias and precision. In the meanwhile, 2,165 atrial fibrillation (AF) patients who initiated direct oral anticoagulants (DOACs) between December 2015 and December 2018 were identified and renal function was assessed by estimated creatinine clearance (eCrCl). Events per 100 patient-years was calculated. Cox proportional hazards regression was applied to compare the incidence of outcomes of each group.Results: Xiangya-s equation demonstrated higher accuracy, lower bias and improved precision when compared with 12 creatinine-based and 2 CysC-based reported equations to estimate GFR in multi-ethnic Chinese CKD patients. When we applied Xiangya-s equation to patients with AF and CKD prescribed DOACs, wide variability was discovered in eCrCl calculated by the Cockcroft-Gault (CG), Modification of Diet in Renal Disease Study (MDRD), Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), Xiangya equation which we had developed for generally patients and Xiangya-s equations, which persisted after grouping by different renal function stages. Equation choice affected drug-dosing adjustments, with the formulas agreeing for only 1.19%, 5.52%, 33.22%, 26.32%, and 36.61% of potentially impacted patients for eCrCl cutoffs of <15, <30, 15–49, 30–49, ≥50 ml/min, respectively. Relative to CG equation, accordance in DOACs dosage was 81.08%, 88.54%, 62.25%, and 47.68% for MDRD, CKD-EPI, Xiangya and Xiangya-s equations for patients with CrCl < 50 ml/min (eCrCl cutoffs of <30, 30–49, ≥50 ml/min), respectively. Reclassification of renal function stages by Xiangya-s equation was significantly associated with stroke or systemic embolism, non-major clinically relevant bleeding and any bleeding events.Conclusion: Xiangya-s equation provides more accurate GFR estimates in Chinese CKD patients who need consecutive monitoring of renal function, which may assist clinicians in choosing appropriate drug dosages.

Background The relationship between vascular calcification and chronic kidney disease is well known. However, whether vascular calcification affects renal function deterioration remains unclear. We investigated whether kidney function deteriorated more rapidly in individuals with higher vascular calcification indicated by the coronary artery calcium score (CACS). Methods and Results Individuals with a normal estimated glomerular filtration rate (>60 mL/min per 1.73 m 2 ) who underwent cardiac computed tomography in our institution (a tertiary teaching hospital in Cheonan, Korea) from January 2010 to July 2012 were retrospectively reviewed. All participants were aged 20 to 65 years. Among 739 patients, 447, 175, and 117 had CACSs of 0, 1 to 99, and ≥100 units, respectively. The participants were followed for 7.8 (interquartile range, 5.5–8.8) years. The adjusted annual estimated glomerular filtration rates declined more rapidly in patients in the CACS ≥100 group compared with those in the CACS 0 group (adjusted‐β, −0.40; 95% CI, −0.80 to −0.03) when estimated using a linear mixed model. The adjusted hazard ratio in the CACS ≥100 group for Kidney Disease: Improving Global Outcomes criteria (a drop in estimated glomerular filtration rate category accompanied by a 25% or greater drop in estimated glomerular filtration rate) was 2.52 (1.13–5.61). After propensity score matching, more prevalent renal outcomes (13.2%) were observed in patients with a CACS of ≥100 compared with those with a CACS of 0 (1.9%), with statistical significance ( P =0.004). Conclusions Our results showed that renal function declined more rapidly in patients with higher CACSs, suggesting that vascular calcification might be associated with chronic kidney disease progression.

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.
