The KDIGO guidelines propose a new approach to diagnose chronic kidney disease (CKD) based on estimated glomerular ®ltration rate (GFR). In patients with a GFR value comprised between 45 and 59 mL/ min/1.73m2 as estimated by the CKD-EPI creatinine equation (eGFRcreat), it is suggested to con®rm the diagnosis with a second estimation using the CKD-EPI cystatin C-based equations (eGFRcys/eGFRcreat-cys). We sought to determine whether this new diagnostic strategy might extend to kidney transplant recipients (KTR) and help to identify those with decreased GFR. In 670 KTR for whom a measured GFR was available, we simulated the detection of CKD using the two-steps approach recommended by the guidelines in comparison to the conventional approach relying on creatinine equation. One hundred forty-®ve patients with no albuminuria had eGFRcreat between 45 and 59 mL/ min/1.73m2. Among them, 23% had inulin clearance over 60 mL/min/1.73m2 and were thus incorrectly classi®ed as CKD patients. When applying the Kidney Disease: Improving Global Outcomes (KDIGO) strategy, 138 patients were con®rmed as having a GFR below 60 mL/min with eGFRcreat-cys. However, 21% of them were misclassi®ed in reference to measured GFR. Our data do no not support the use of cystatin C as a con®rmatory test of stage 3A CKD in KTR. [less ▲]

Previous data suggested that allo-SCT might be an effective therapy in the setting of chemo-refractory/relapsed diseases because of the potent long-term immune-mediated tumor control. This retrospective study aimed to analyze the outcome of adult patients who received allo-SCT in a chemo-refractory/relapsed status. The series included 840 patients with active or progressive disease at the time of transplant. Median age was 50 years. With a median follow-up of 40 months, 3-year OS, disease-free survival (DFS), and non-relapse mortality rates were 29±2, 23±2, and 30±2%, respectively. At the last follow-up, 252 patients (30%) were still alive (of whom 201 were in CR (24%). In a Cox multivariate analysis, the use of a reduced-intensity conditioning (RIC) before allo-SCT and use of an HLA-identical sibling donor remained independently associated with a better OS (hazard ratio (HR)¼0.82; 95% confidence interval (CI), 0.69–0.98, P¼0.03; and HR¼0.79; 95% CI, 0.66–0.93, P¼0.006, respectively). Also, a diagnosis of myelodysplastic syndrome/myeloproliferative disorder, Hodgkin lymphoma and non-Hodgkin lymphoma compared with acute leukemia had a favorable impact on OS (HR¼0.55; 95% CI, 0.45–0.68, Po0.0001; HR¼0.49; 95% CI, 0.31–0.75, P¼0.001; and HR¼0.47; 95% CI, 0.35–0.63, Po0.0001, respectively). In conclusion, this study suggests that allo-SCT may be of benefit in some subgroups of patients with active or progressive hematological malignancies at the time of allo-SCT. [less ▲]

Among issues susceptible to hamper a reliable measurement of inulin clearance, those regarding the dosage of inulin are largely neglected. We have compared the analytical performances of 2 commonly used methods of inulin dosage (one “acid” and one “enzymatic” method) and studied their potential impact on the glomerular filtration rate (GFR) value given by inulin clearance. Repeatability, uncertainty and the beta-expectation limits were evaluated from pre-determined serum and urine pools of inulin. Agreement between the two methods was analyzed from 99 inulin clearances performed in renal transplant patients. Impact of the method of dosage on GFR evaluation was simulated according to the respective beta-expectations limits of each method. Overall, intra-assay coefficient of variability and relative bias were inferior to 5% and 10% for both methods. Contrary to the acid method, analytical performance of the enzymatic method was not influenced by the presence of glucose. The relative difference in GFR values obtained with the two methods in transplant patients was − 0.4 ± 10%. Simulations suggested that changes in inulin concentration attributable to analytical error could modify the value of GFR from − 12% to + 28%. In conclusion, while analytical performances are globally acceptable for both methods, they are not strictly equivalent. The impact on the determination of GFR, albeit limited, is not negligible and adds to other sources of inaccuracy. International standardization for the dosage of inulin is necessary. [less ▲]
