Number Of Individuals

The widely used Modification of Diet in Renal Disease (MDRD) formula adapts a 1.212 multiplier for individuals who are identified as African Americans (AAs) or Blacks, which leads to a higher GFR estimation. As it stands, AAs have a lower prevalence of chronic kidney disease (CKD) but higher incidence of end-stage renal disease (ESRD) compared with Whites. Many hypotheses have been postulated to explain this paradox, but the imprecision of the GFR estimation with race-adaptation could be contributory. We performed a single-center, longitudinal, retrospective study on a cohort of outpatient AA patients using the MDRD and MDRDrace removed and CKD-EPI and CKD-EPIrace removed and their progression to CKD G5 (eGFR <15 ml/min/1.73 m2). 327 patients were analyzed. Median follow-up was 88.1 months (interquartile range, 34.4–129.1). When race was removed from MDRD, 39.9% of patients in CKD G1/2 were reclassified to CKD G3a, 72.6% of patients in CKD G3a would be reclassified to CKD G3b, and 54.1% and 36.4% of patients would be reclassified from CKD 3b to CKD G4 and CKD G4 to CKD G5, respectively p < 0.0001 . Comparing the CKD-EPI formula against the MDRD in our cohort, we found that 8.2%, 18.8%, and 11.4% of patients were reclassified from CKD G1/2 to CKD G3a, CKD G3a to G3b, and CKD G3b to CKD G4 respectively. Overall median time to progression to CKD G5 was 137.4 (131.9–142.8) months in patients who were not reclassified and 133.6 (127.6–139.6) months for patients who were reclassified by MDRDrace removed p < 0.288 . Concerns of inequitable access to healthcare have elicited calls to review race-corrected eGFR equations. A substantial number of individuals would have their CKD stage reclassified should have the MDRDrace removed equation be adopted en masse on an AA-only population. The discrepancy is highest at the 45–59 and >60 ml/min/1.72 min2 ranges. This will have tremendous impact on our center’s approach to pharmacological dosing, referral system, best practices, and outcome surveillance. Comprehensive review of the current “race-corrected” eGFR will require a multifaceted approach and adjunctive use of noncreatinine-based approach.

Abstract Background and Aims Glomerulonephritis (GN) is one of common causes of end-stage renal disease (ESRD) in Korea as well as in the world, however, it is underdiagnosed as a cause of chronic kidney disease. The incidence and prevalence of GNs are different according to periods and countries. We report trends of pathologic diagnosis of nephritis from 18 centers throughout Korea during last 40 years. Method We enrolled 21,617 patients having native kidney biopsy for diagnosis of nephritis between 1979 and 2018, retrospectively. We excluded 191 patients diagnosed as cancer or tumor and analyzed the data of 21,426 patients. We defined the primary GN as IgA nephropathy (IGAN), minimal change disease (MCD), membranous nephropathy (MGN), focal segmental glomerulosclerosis (FSGS), membranoproliferative GN (MPGN), and C3 glomerulopathy (C3G). The estimated glomerular filtration rate (GFR) was calculated by original MDRD equation for adults and by height-independent equation for children. The final outcomes were incidences of end stage renal disease (ESRD) and death. Results There were 22,203 pathologic diagnoses including 777 patients with two kinds of pathologic diagnosis. The age was 42.1 ± 17.7 years at renal biopsy. There were 11565 (54.0 %) men and 976 (4.6 %) children &lt;18 years. The frequencies of hypertension and diabetes mellitus were 53.0 % (10994) and 14.0 % (2833), respectively. Mean levels of serum creatinine, GFR, and urine protein to creatinine ratio were 1.62 ± 1.89 mg/dl, 77.1 ± 60.4 ml/min/1.73 m2, and 3.305 ± 4.164 g/g cr, respectively. The prevalence of GN was 78.45% (17419 diagnoses), followed by tubulointerstitial nephritis (8.84 %), abnormality in glomerular basement membrane (3.43 %), ischemic nephropathies (1.73 %), paraproteinemia related lesions (1.36 %), infection (0.12 %). There were non-specific GN (3.65 %), normal pathology (2.46 %), advanced global sclerosis (1.77 %), inadequate specimen (0.96 %), and miscellaneous lesions (0.12 %), also. The most frequent diagnosis was IGAN (34.17%, 7586 diagnoses), followed by MGN (9.17%), MCD (9.13 %), FSGS (7.65 %), lupus nephritis (LN) (6.30 %), diabetic nephropathy (DMN) (3.99 %), MPGN and C3G (2.79 %), therefore, prevalence of primary GN was 62.90 %. The frequency of IGAN had been increased from 19.9 % at the period of 1979-1989 to 41.4 % at the period of 2005-2009 and then stabilized to 36.0-36.7%. The frequencies of MCD, MGN, and FSGS were not changed since 1990. However, the frequency of MPGN was decreased from 4.7-5.7 % at the period of 1979-1999 to 2.5 % at the period of 2015-2018. The frequency of LN was decreased and that of DMN was increased from 2.5-3.1% during 1990-2009 to 6.3 % during 2015-2018 which might be related to the pathologic classification of DMN, published at 2010 by Tervaert TW et al. The incidences of ESRD and death were 13.3 % (2663/20010 patients) and 2.9 % (608/20884 patients) during follow-up period of 82.6 months (median) for ESRD and 91.5 months (median) for mortality after biopsy. Among patients with primary GN, patients with MCD showed the best prognosis for ESRD, followed by patients with MN, IGAN, FSGS, MPGN, and C3G (p &lt;0.001) by Cox’s hazard proportional model adjusted by risk factors related to ESRD. Prognosis for mortality was not different among patients with MCD, MN, IGAN, and FSGS, but, patients with C3G showed the worst prognosis for mortality (p=0.006). Conclusion IGAN was the most frequent diagnosis followed by MGN and MCD. Compared to Western countries, IGAN and MCD are more prevalent in Korea, while MGN and FSGS are less prevalent. The frequencies of MPGN and LN had been decreased since 2000. The patients with MPGN and C3G showed the worst prognosis.

Abstract Background and Aims Renal involvement is a severe manifestation of ANCA-associated vasculitis. Patients often progress to end-stage renal disease. The potential for renal recovery after a first flare has seldom been studied. Our objectives were to describe the evolution of the estimated glomerular filtration rate (eGFR) and identify factors associated with the change in eGFR between diagnosis and follow-up at 3 months (ΔeGFRM0–M3) in a cohort of patients with a first flare of pauci-immune glomerulonephritis. Methods This was a retrospective study over the period 2003–2018 of incident patients in the Nord-Pas-de-Calais (France). Patients were recruited if they had a first histologically-proven flare of pauci immune glomerulonephritis with at least 1 year of follow up. Kidney function was estimated with MDRD-equation and analysed at diagnosis, 3rd, 6th and 12th months. The primary outcome was ΔeGFRM0–M3. Factors evaluated were histological (Berden classification, interstitial fibrosis, percentage of crescents), clinical (extra-renal manifestations, sex, age) or biological (severity of acute kidney injury, dialysis, ANCA subtype). Results One hundred and seventy-seven patients were included. The eGFR at 3 months was significantly higher than at diagnosis (mean ± standard deviation, 40 ± 24 vs 28 ± 26 ml/min/1.73 m2, p &lt; 0.001), with a ΔeGFRM0–M3 of 12 ± 19 ml/min/1.73 m2. The eGFR at 12 months was higher than at 3 months (44 ± 13 vs 40 ± 24 ml/min/1.73m2, p = 0.003). The factors significantly associated with ΔeGFRM0–M3 in univariate analysis were: sclerotic class according to Berden classification, percentage of interstitial fibrosis, percentage of cellular crescents, acute tubular necrosis, neurological involvement. The factors associated with ΔeGFRM0–M3 in multivariate analysis were the percentage of cellular crescents and neurological involvement. The mean increase in eGFR was 2.90 ± 0.06 ml/min/1.73m2 for every 10-point gain in the percentage of cellular crescents. ΔeGFRM0–M3 was not associated with the risks of end-stage renal disease or death in long-term follow-up. Conclusions Early renal recovery after a first flare of pauci-immune glomerulonephritis occurred mainly in the first three months of treatment. The percentage of cellular crescents was the main independent predictor of early renal recovery.

Background: Dyslipidemia contributes to the high cardiovascular risk in end stage renal disease (ESRD) or in dialysis patients; however, it remains an underestimated problem. Objective: To see the extent of dyslipidemia in patients of end stage renal disease i.e. chronic kidney disease (CKD) stage 5 who underwent hemodialysis or peritoneal dialysis procedure. Materials and Methods: This cross-sectional study was conducted from September 2016 to March 2018 Bangabandhu Sheikh Mujib Medical University (BSMMU) on 55 CKD (stage 5) patients where 31 in hemodialysis (HD) (group A) and 24 in continuous ambulatory peritoneal dialysis (CAPD) (group B). Serum lipid profile was estimated in both groups by using the standard laboratory technique. Results: Dialysis adequacy (Kt/V) was found 1.46 for HD patients (group A) and 1.81 for CAPD patients (group B).All serum lipids were higher in amount in CAPD patients than HD patients-total cholesterol (222.3±24.2 mg/dl vs. 198.9±28.4 mg/dl; p<0.05), triglycerides (179.6±24.7 mg/dl vs. 176.6±24.4 mg/dl; p<0.05), HDL cholesterol (40.8±3.90 mg/dl vs. 38.5±4.95 mg/dl; p>0.05) and LDL cholesterol (145.5±22.1 mg/dl vs. 123.2±26.5 mg/dl; p<0.05). Besides, dyslipidemia was more evident in CAPD patients than HD patients, as per raised serum total cholesterol (83.33% vs. 70.97%), raised triglycerides (95.83% vs. 83.87%), raised LDL (100% vs. 77.42%) and lowering of HDL cholesterol (87.5% vs. 80.65%) were found more in group B in comparison to group A. Conclusion: Dyslipidemic risk factors are highly evident in dialysis patients and the extent of dyslipidemia is observed more in CAPD than HD patients.

Abstract Background and Aims Renal transplantation is considered the most effective and less costly modality of renal replacement therapy in patients with end stage renal disease. The disparity between kidney allografts and recipients has led to a global effort to increase the pool of kidney donors. Accordingly, fibromuscular dysplasia (FMD) is no longer considered an absolute contraindication for kidney donation. The incidence of FMD is about 2.3%-5.8% in potential kidney donors. There are few cases in the literature where renal artery stenosis in allografts with known pre-transplantation FMD became worse after transplantation, indicating the importance of a proper follow up in the recipients. This is a case of a living kidney donor with no history of hypertension, proteinuria or elevated serum creatinine, whose intra-arterial digital subtraction angiography revealed FMD lesions in the left renal artery. Method Case report Results A 54-year-old Caucasian female with medical history of hypothyroidism took the decision to offer her kidney to her 37-year-old son who was diagnosed with end-stage renal disease five years ago secondary to diabetes mellitus type I. She had no history for diabetes, hypertension and renal disease. Her vital signs on admission were heart rate of 78 beats/min and blood pressure of 130/70 mmHg. Urinalysis, biochemical profile and serological evaluations were all within normal ranges. Blood urea was 36 mg/dL and serum creatinine was 0.6 mg/dL (eGFR 97ml/min/1.73m2). The abdominal ultrasound and renogram with Tc-99m DTPA showed no remarkable findings. On intra-arterial digital subtraction angiography an abnormal succession of dilatations and multifocal stenoses of the left renal artery, characteristic of medial FMD, was found. The right renal artery was normal. Apart from a dysfunctional permanent left femoral catheter, the patient had no other vascular access for hemodialysis because of Superior Vena Cava syndrome, so he needed urgent transplantation. Taking all of these into consideration, the patient was offered renal transplantation as the best option. A left open donor nephrectomy was performed; the renal artery was divided distal to the stenotic dysplastic area. The allograft was placed at the right iliac fossa of the recipient with arterial and venous anastomosis to the extrarenal iliac vessels. Post-operatively, the recipient had a delayed graft function lasted 13 days. On renal artery Doppler in the allograft we found increased resistance index (RI) that gradually normalized without any intervention. An immunosuppressive regiment of tacrolimus, mycophenolate and prednisone was administered according to our center protocol. At discharge serum creatinine was 1.7 mg/dL (eGFR: 50ml/min/1.73m2). At the year follow-up, the donor was normotensive and had near normal renal function (Cr:1.3mg/dL, eGFR: 70ml/min/1.73m2). The recipient has a well-controlled blood pressure receiving two antihypertensive drugs and maintains a satisfactory renal function. Conclusion Few cases with FMD in renal allografts from living and deceased donors have been described. In a review of 4 studies the authors concluded that the outcome of transplantation with allografts from living donors with medial FMD was satisfactory and these allografts could be used to increase the donor pool. Furthermore, it is strongly recommended to have a thorough pre-transplantation check of the donor as well as a close monitoring of both the donor and recipient after transplantation. This case shows that allografts harvested from carefully selected donors with renal arterial FMD can be successfully used, particularly in urgent conditions. Detailed pre-tranplantation imaging of donor’s renal arteries, selection of the appropriate screening method, as well as close monitoring of both donor and recipient for early interventions after transplantation is of paramount importance.

ObjectiveTo examine whether lifestyle factors, including sedentary time and physical activity, could independently contribute to risk of end-stage renal disease (ESRD).Study designCase-cohort study.SettingSouth-eastern USA.ParticipantsThe Southern Community Cohort Study recruited ~86 000 black and white participants from 2002 to 2009. We assembled a case cohort of 692 incident ESRD cases and a probability sample of 4113 participants.PredictorsSedentary time was calculated as hours/day from daily sitting activities. Physical activity was calculated as metabolic equivalent (MET)-hours/day from engagement in light, moderate and vigorous activities.OutcomesIncident ESRD.ResultsAt baseline, among the subcohort, mean (SD) age was 52 (8.6) years, and median (25th, 75th centile) estimated glomerular filtration rate (eGFR) was 102.8 (85.9–117.9) mL/min/1.73 m2. Medians (25th–75th centile) for sedentary time and physical activity were 8.0 (5.5–12.0) hours/day and 17.2 (8.7–31.9) MET-hours/day, respectively. Median follow-up was 9.4 years. We observed significant interactions between eGFR and both physical activity and sedentary behaviour (p<0.001). The partial effect plot of the association between physical activity and log relative hazard of ESRD suggests that ESRD risk decreases as physical activity increases when eGFR is 90 mL/min/1.73 m2. The inverse association is most pronounced at physical activity levels >27 MET-hours/day. High levels of sitting time were associated with increased ESRD risk only among those with reduced kidney function (eGFR ≤30 mL/min/1.73 m2); this association was attenuated after excluding the first 2 years of follow-up.ConclusionsIn a population with a high prevalence of chronic kidney disease risk factors such as hypertension and diabetes, physical activity appears to be associated with reduced risk of ESRD among those with preserved kidney function. A positive association between sitting time and ESRD observed among those with advanced kidney disease is likely due to reverse causation.
