Abstract

Rituximab (RTX) therapy for primary focal segmental glomerulosclerosis recurrence after kidney transplantation (KT) has been extensively debated. We aimed to assess the benefit of adding RTX to plasmapheresis (PP), corticosteroids, and calcineurin inhibitors (standard of care, SOC). We identified 148 adult patients who received KT in 12/2004-12/2018 at 21 French centers: 109 received SOC (Group 1, G1), and 39 received immediate RTX along with SOC (Group 2, G2). In G1, RTX was introduced after 28 days of SOC in the event of failure (G1a, n = 19) or PP withdrawal (G1b, n = 12). Complete remission (CR) was achieved in 46.6% of patients, and partial remission (PR) was achieved in 33.1%. The 10-year graft survival rates were 64.7% and 17.9% in responders and nonresponders, respectively. Propensity score analysis showed no difference in CR+PR rates between G1 (82.6%) and G2 (71.8%) (p = .08). Following the addition of RTX (G1a), 26.3% of patients had CR, and 31.6% had PR. The incidence of severe infections was similar between patients treated with and without RTX. In multivariable analysis, infection episodes were associated with hypogammaglobulinemia

Abstract

International audience; Introduction - SARS-CoV-2 pandemic evolved in 2 consecutive waves during 2020. Improvements in the management of COVID-19 led to a reduction in mortality rates among hospitalized patients during the second wave. Whether this progress benefited kidney transplant recipients (KTRs), a population particularly vulnerable to severe COVID-19, remained unclear. Methods - In France, 957 KTRs were hospitalized for COVID-19 in 2020 and their data were prospectively collected into the French Solid Organ Transplant (SOT) COVID registry. The presentation, management, and outcomes of the 359 KTRs diagnosed during the first wave were compared to those of the 598 of the second wave. Results - Baseline comorbidities were similar between KTRs of the 2 waves. Maintenance immunosuppression was reduced in most patients but withdrawal of antimetabolite (73.7% vs. 58.4%, < 0.001) or calcineurin inhibitor (32.1% vs. 16.6%, < 0.001) was less frequent during the second wave. Hydroxychloroquine and azithromycin that were commonly used during the first wave (21.7% and 30.9%, respectively) but were almost abandoned during the second wave. In contrast, the use of high dose corticosteroids doubled (19.5% vs. 41.6%, < 0.001). Despite these changing trends in COVID-19 management, 60-day mortality was not statistically different between the 2 waves (25.3% vs. 23.9%; Log Rank, = 0.48) and COVID-19 hospitalization period was not associated with death due to COVID-19 in multivariate analysis (Hazard ratio 0.89, 95% confidence interval 0.67-1.17, = 0.4). Conclusion - We conclude that changing of therapeutic trends during 2020 did not reduce COVID-19 related mortality among KTRs. Our data indirectly support the importance of vaccination and neutralizing monoclonal anti-SARS-CoV-2 antibodies to protect KTRS from severe COVID-19.

Abstract

BACKGROUND: COVID-19 has been associated with high morbidity and mortality in kidney transplant recipients. However, risk factors for COVID-19 disease in patients with kidney transplants remain poorly defined. METHODS: We enrolled patients who underwent kidney transplantation and were actively followed up in two hospitals in Paris on March 1st, 2020. Patients were screened for baseline and transplant characteristics, functional parameters, comorbidities, and immunosuppressive therapies. COVID-19 disease was assessed. Patients were followed up during the pandemic until April 30th, 2020 by the COVID-19 SLS KT survey program, including teleconsulting, at-home monitoring for patients with COVID-19, and a dedicated phone hotline platform. RESULTS: Among 1216 patients with kidney transplants enrolled, 66 (5%) patients were identified with COVID-19 disease, which is higher than the incidence observed in the general population in France (0.3%). Their mean age was 56.4±12.5 years, and 37 (56%) patients were men. The following factors were independently associated with COVID-19 disease: non-White ethnicity (adjusted odds ratio [OR], 2.17; 95% confidence interval [95% CI], 1.23 to 3.78; P=0.007), obesity (OR, 2.19; 95% CI, 1.19 to 4.05; P=0.01), asthma and chronic pulmonary disease (OR, 3.09; 95% CI, 1.49 to 6.41; P=0.002), and diabetes (OR, 3.33; 95% CI, 1.92 to 5.77; P

Abstract

International audience; End stage kidney disease increase the risk of COVID-19 related death but how the kidney replacement strategy should be adapted during the pandemic is unknown. Chronic hemodialysis makes social distancing difficult to achieve. Alternatively, kidney transplantation could increase the severity of COVID-19 due to therapeutic immunosuppression and contribute to saturation of intensive care units. For these reasons, kidney transplantation was suspended in France during the first epidemic wave. Here, we retrospectively evaluated this strategy by comparing the overall and COVID-19 related mortality in kidney transplant recipients and candidates over the last three years. Cross-interrogation of two national registries for the period 1 March and 1 June 2020, identified 275 deaths among the 42812 kidney transplant recipients and 144 deaths among the 16210 candidates. This represents an excess of deaths for both populations, as compared with the same period the two previous years (mean of two previous years: 253 in recipients and 112 in candidates). This difference was integrally explained by COVID-19, which accounted for 44% (122) and 42% (60) of the deaths in recipients and candidates, respectively. Taking into account the size of the two populations and the geographical heterogeneity of virus circulation, we found that the excess of risk of death due to COVID-19 was similar for recipients and candidates in high viral risk area but four-fold higher for candidates in the low viral risk area. Thus, in case of a second epidemic wave, kidney transplantation should be suspended in high viral risk areas but maintained outside those areas, both to reduce the excess of deaths of candidates and avoid wasting precious resources.

Abstract

Background The access of obese patients to kidney transplantation is limited despite several studies showing that obese transplant recipients had a better survival rate than those undergoing dialysis. The aim of this study was to compare patient and graft survival rates and post-renal transplant complications in obese patients and non-obese patients and to assess the effect of pre-transplant weight loss in obese patients on transplant outcomes. Methods We carried out a prospective cohort study using two French registries, the Renal Epidemiology and Information Network and CRISTAL, on 7270 kidney transplant patients between 2008 and 2014 in France. We compared obese patients with non-obese patients and obese patients who lost more than 10% of weight before the transplant (obese WL and obese nWL). Results The mean BMI in our obese patients was 32 kg/m2. Graft survival was lower in obese patients than in non-obese patients {hazard ratio (HR) = 1.40, [95% confidence interval (95% CI) 1.09; 1.78], P = 0.007}, whereas patient survival was similar [HR = 0.94, (95% CI 0.73; 1.23), P = 0.66]. Graft survival was significantly lower in obese WL than in obese nWL [HR = 2.17, (1.02; 4.63), P = 0.045], whereas patient survival was similar in the two groups [HR = 0.79, (0.35; 1.77), P = 0.56]. Conclusion Grade 1 obesity does not seem to be a risk factor for excess mortality after kidney transplantation and should not be an obstacle to having access to a graft. Weight loss before a kidney transplant in these patients should not be essential for registration on waiting list.

Abstract

International audience; There are no studies which have compared the risk of severe Covid-19 and related mortality between transplant recipients and non-transplant patients. We enrolled two groups of patients hospitalized for Covid-19, i.e., kidney transplant recipients from the French Registry of Solid Organ Transplant (n=306) and a single-center cohort of non-transplant patients (n=795). An analysis was performed among subgroups matched for age and risk factors for severe Covid-19 or mortality. Severe Covid-19 was defined as admission (or transfer) to an intensive care unit, need for mechanical ventilation, or death.Transplant recipients were younger and had more comorbidities compared to non-transplant patients. They presented with higher creatinine levels and developed more episodes of acute kidney injury. After matching, the 30-day cumulative incidence of severe Covid-19 did not differ between KTR and non-transplant patients; however, 30-day Covid-19-related mortality was significantly higher in KTR (17.9% versus 11.4%, respectively, p=0.038). Age >60 years, cardiovascular disease, dyspnea, fever, lymphopenia, and C-reactive protein (CRP) were associated with severe Covid-19 in univariate analysis, whereas transplant status and serum creatinine levels were not. Age >60 years, hypertension, cardiovascular disease, diabetes, CRP >60 mg/L, lymphopenia, kidney transplant status (HR=1.55), and creatinine level >115 µmol/L (HR=2.32) were associated with Covid-19-related mortality in univariate analysis. In multivariable analysis, cardiovascular disease, dyspnea, and fever were associated with severe disease, whereas age >60 years, cardiovascular disease, dyspnea, fever, and creatinine level>115 µmol/L retained their independent associations with mortality. Kidney transplant recipients had a higher Covid-19-related mortality compared to non-transplant hospitalized patients.

Abstract

Notwithstanding the ongoing coronavirus disease-2019 (Covid-19) pandemic, information on its clinical presentation and prognosis in recipients of a kidney transplant remain scanty. The aim of this registry-based observational study was to explore characteristics and clinical outcomes of recipients of kidney transplants included in the French nationwide Registry of Solid Organ Transplant Recipients with Covid-19. Covid-19 was diagnosed in symptomatic patients who had a positive PCR assay for SARS-CoV-2 or having typical lung lesions on imaging. Clinical and laboratory characteristics, management of immunosuppression, treatment for Covid-19, and clinical outcomes (hospitalization, admission to intensive care unit, mechanical ventilation, or death) were recorded. Risk factors for severe disease or death were determined. Of the 279 patients, 243 were admitted to hospital and 36 were managed at home. The median age of hospitalized patients was 61.6 years; most had comorbidities (hypertension, 90.1%; overweight, 63.8%; diabetes, 41.3%; cardiovascular disease, 36.2%). Fever, cough, dyspnea, and diarrhea were the most common symptoms on admission. Laboratory findings revealed mild inflammation frequently accompanied by lymphopenia. Immunosuppressive drugs were generally withdrawn (calcineurin inhibitors: 28.7%; antimetabolites: 70.8%). Treatment was mainly based on hydroxychloroquine (24.7%), antiviral drugs (7.8%), and tocilizumab (5.3%). Severe Covid-19 occurred in 106 patients (46%). Forty-three hospitalized patients died (30-day mortality 22.8%). Multivariable analysis identified overweight, fever, and dyspnea as independent risk factors for severe disease, whereas age over 60 years, cardiovascular disease, and dyspnea were independently associated with mortality. Thus, Covid-19 in recipients of kidney transplants portends a high mortality rate. Proper management of immunosuppression and tailored treatment of this population remain challenging., Graphical abstract

Abstract

Background and Aims The indication of rituximab (RTX) in the treatment of primary focal segmental glomerulosclerosis (FSGS) recurrence after kidney transplantation (KT) remains controversial. The objective of our study was to evaluate the benefit and tolerability of adding RTX to the standard of care (SOC) comprising plasmapheresis (PP), corticosteroids, and high-dose anticalcineurins for the treatment of FSGS recurrence after KT. Method This retrospective, multicenter study reports on 148 patients, transplanted between 31 December 2004 and 31 December 2018, aged 39.9 + 13.4 years, who developed FSGS recurrence at 7 [3–23] days. In all 109 patients received a SOC (Group 1). RTX was introduced in this group after more than 28 days of SOC for failure or for therapeutic intensification (n = 19, Group 1a), or for early discontinuation of PP (n = 12, Group 1b); 39 patients received RTX associated at the outset with SOC (Group 2). Results We observed 46.6% complete remission (CR) and 33.1% partial remission (PR). Ten-year graft survival was 65.6% [51.4–76.6] and 13.4% [3.4–30.0] in responders and non-responders respectively. There was no difference in CR + PR rate between G1 (82.5%) and G2 (71.8%), p = 0.08, confirmed by propensity score +4.3% (95% CI [−9.0%-17.5%], p = 0.53). Following addition of RTX (Group 1a), we observed a CR rate of 26.3% and a PR rate of 31.6%. Patients with and without RTX experienced similar rejection rates (18.6% and 28.2%, p = 0.17) and infection rates (71.4% and 79.5%, p = 0.40). In multivariate analysis, the infections were associted with hypogammaglobulinemia Conclusion Rituximab could be used in cases of SOC failure or in remission patients for early weaning of plasmapheresis, without increasing infectious risk.

Abstract

Post-kidney transplantation outcomes in obese patients remain uncertain. The aim of this study is to compare patient and graft survival and post-transplant complications in obese patients and non-obese patients. We performed a retrospective analysis of a sample of 245kidney transplantations performed between 2008 and 2014 in Clermont-Ferrand. Obese patients and non-obese patients have been compared. Then we compared obese patients who have lost at least 5% of their weight (OPP) with obese patients who did not lose weight (OPS), and non-obese patients who have lost at least 5% of their weight (NOPP) with non-obese patients who did not lose weight (NOPS). Patient survival at 5years is similar between obese and non obese (84.06% versus 90.96%; P=0.49), between OPP and OPS (88.89% versus 81.82%; P=0.34) and between NOPP and NOPS (89.19% versus 91.05%; P=0.73). At 5years, graft survival is also comparable between obese and non obese (88.82% versus 81.86%; P=0.58), between OPP and OPS (85.56% versus 91.06%; P=0.98) and between NOPP and NOPS (88% versus 80.12%; P=0.31). The length of hospitalization and the rate of complications seem similar between obese and non obese and between OPP and OPS. Post-transplantation outcomes are similar between obese and non-obese patients and a weight loss for obese patients does not seem to decrease the risk of post-transplant complication.

Abstract

Focal segmental glomerulosclerosis (FSGS) is a common cause of nephrotic syndrome in child and adult. The collapsing forms are of poor renal prognosis and are usually secondary to viral infections with, first and foremost, the human immunodeficiency virus. Among other viral etiologies, cytomegalovirus (CMV) is an uncommon cause. We report a case of a 32years-old patient with collapsing focal segmental glomerulosclerosis induced by cytomegalovirus with initial acute renal failure and proteinuria at 12.4g/24h. The treatment associated ganciclovir during 7days followed by valganciclovir during 14days and steroids at 1mg/kg/day. Renal function improved and proteinuria decreased with this treatment. Proteinuria increase again 3weeks after valganciclovir discontinuation while CMV Polymerase chain reaction (PCR) was positive. Therefore, valganciclovir has been resumed allowing renal function normalization and decrease in proteinuria to 4g/24h after negative CMVPCR assay after 15weeks. Anti-CMV therapy combined with steroids seems to provide a renal response in case of FSGS induced by CMV even if long-term prognosis stays uncertain.

Abstract

Introduction Durant la pandemie de COVID-19, peu d’informations concernant la presentation clinique et le pronostic de cette infection chez les patients transplantes d’organe ont ete rapportees. Description Nous avons mis en place un registre francais sous l’egide de la Societe francophone de transplantation pour recenser tous les cas de patients transplantes developpant une infection a SARS-CoV-2 a partir du 1er mars 2020. Methodes L’infection a ete diagnostiquee chez des patients avec un frottis positif en RT-PCR ou en presence de lesions pulmonaires typiques. Les caracteristiques cliniques et biologiques, la gestion de l’immunosuppression, le traitement du COVID-19 et l’evolution de la maladie ont ete colliges. La severite etait definie par : admission ou transfert en reanimation, ventilation mecanique ou deces. Resultats Sur les 279 patients transplantes renaux recenses dans le Registre, 243 ont ete admis a l’hopital et 36 ont ete pris en charge a domicile. L’âge des patients hospitalises etait de 61,6 ans et la plupart presentaient des comorbidites (hypertension : 90 % ; surpoids : 64 % ; diabete : 41 % ; maladies cardiovasculaires : 36 %). La fievre, la toux, la dyspnee et la diarrhee etaient les symptomes les plus frequents. Les anti-metabolites etaient interrompus dans 70,8 des cas. Le traitement a comporte de l’hydroxychloroquine dans 25 % des cas, un antiviral pour 7,8 % des patients et du tocilizumab chez 5,3 %. Des formes severes de COVID-19 sont survenues chez 106 patients (46 %). Quarante-trois patients sont decedes (taux de mortalite a 30 jours : 22,8 %). Une analyse multivariable a permis d’identifier le surpoids, la fievre et la dyspnee comme facteurs de risque independants de maladie severe, alors que l’âge > 60 ans, un antecedent de maladie cardiovasculaire et la dyspnee etaient independamment associes a la mortalite. Conclusion Les transplantes renaux developpant une infection a SARS-Cov-2 ont un taux de mortalite eleve. La bonne gestion de l’immunosuppression et une prise en charge adaptee restent un defi.

Abstract

The impact of immunosuppressive therapy (IS) strategies after kidney transplant failure (KTF) on potential future new grafts is poorly established. We assessed the potential benefit of calcineurin inhibitor (CNI)-based IS maintenance throughout the dialysis period on the outcome of the second kidney transplant (KT). We identified 407 patients who underwent a second KT between January 2008 and December 2018 at four French KT centers. Inverse probability of treatment weighting was used to control for potential confounding. We included 205 patients with similar baseline characteristics at KTF: a total of 53 received at least CNIs on the retransplant day (G-CNI), and 152 did not receive any IS (G-STOP). On the retransplant date, G-STOP patients experienced a longer pretransplant dialysis time, were more often hyperimmunized, and underwent more expanded-criteria donor KTs than G-CNI patients. During the second KT follow-up period, rejection episodes were similar in both groups. The 10-year survival rates without death and dialysis were 98.7% and 59.5% in G-CNI and G-STOP patients, respectively. In the multivariable analysis, CNI-based IS maintenance was associated with better survival (hazard ratio: 0.08; 95% confidence interval: 0.01–0.58, p = 0.01). CNI-based IS maintenance throughout the dialysis period after KTF may improve retransplantation outcomes.

Abstract

Introduction En transplantation renale, les consequences de l’obesite sur la survie du patient et du greffon demeurent incertaines. L’objectif de cette etude est de comparer la survie du patient et du greffon et les complications post transplantation renale entre obeses et non obeses et d’evaluer l’impact d’une perte de poids pre-greffe des sujets obeses sur les resultats post-transplantation. Patients/Materiels et methodes Nous avons mene une etude de cohorte prospective a partir des registres REIN et CRISTAL sur 12 094 patients transplantes renaux entre 2008 et 2014 en France. Nous avons compare les patients obeses aux patients non obeses et les obeses ayant perdu plus de 10 % de poids avant la greffe (OPP) aux patients obeses a poids stable (OPS). Observation/Resultats La survie du patient est comparable entre obeses et non obeses (HR = 0,97, IC 95 % [0,79 ; 1,9], p = 0,10) mais les sujets obeses, compares aux non obeses, ont une moindre survie du greffon (HR = 1,41, IC 95 % [1,18 ; 1,69], p Discussion Nos resultats sur la survie du patient sont en accord avec les donnees recentes de la litterature qui retrouvent une survie du patient similaire chez les sujets obeses compares aux non obeses. Dans notre travail, la perte de poids avant greffe est deletere sur les resultats post-transplantation chez les sujets obeses. Ceci pourrait etre en partie secondaire a la duree de dialyse avant transplantation, plus longue chez les OPP que chez les OPS (3 [2 ; 6] versus 3 [2 ; 4] ans, p Conclusion L’obesite ne semble pas etre un facteur de risque de surmortalite apres transplantation renale. Et la perte de poids pre greffe chez les sujets obeses est deletere tant sur la survie du patient que sur la survie du greffon et ne semble donc pas recommandee.

Abstract

Introduction Le depistage et la correction d’une carence martiale est indispensable pour le traitement de l’anemie chez les patients hemodialyses chroniques. Actuellement, les marqueurs biologiques utilises (coefficient de saturation de la transferrine (CST) et ferritine) ne sont pas suffisamment fiables pour depister ces carences notamment en cas d’inflammation ou de denutrition. L’objectif de cette etude etait d’evaluer la capacite du fer serique a predire la reponse de l’hemoglobine a une supplementation martiale intraveineuse chez les patients hemodialyses. Patients et methodes Nous avons realise une etude retrospective chez 92 patients hemodialyses durant l’annee 2016 pour lesquels une supplementation martiale intraveineuse avait ete debutee. Un patient repondeur a ete defini par une augmentation de l’hemoglobine superieure ou egale a 1 g/dL/mois et/ou une baisse de la dose d’agent stimulant l’erythropoiese (ASE) apres deux mois de supplementation martiale. Resultats Chez les patients repondeurs le fer serique etait significativement plus bas (6,737 ± 2,718 μmol/L) par rapport au patients non repondeur (8,959 ± 2,965 μmol/L, p Discussion Le fer serique represente le fer biodisponible accessible a l’erythroblaste medullaire pour la synthese de son hemoglobine. Il apparait donc logique qu’il permette de predire au mieux et de facon simple et peu couteuse la reponse a une supplementation martiale. Conclusion Un fer serique
