Abstract: International audience; Disseminated toxoplasmosis is infrequent after kidney transplant transmission but life‐threatening because of a lack of diagnostic suspicion as well as specific chemoprophylaxis recommendations. Solid organ transplantation has resulted in few cases of disseminated toxoplasmosis presenting with associated hemophagocytic syndrome. Herein, we report, within the context of a donor/receiver mismatch, a case of a toxoplasmosis associated with hemophagocytic syndrome in a kidney transplant recipient. Molecular and serological investigations confirmed Toxoplasma gondii transmission through the kidney graft.

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: Background Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis worldwide. IgA is mainly produced by the gut-associated lymphoid tissue (GALT). Both experimental and clinical data suggest a role of the gut microbiota in this disease. We aimed to determine if an intervention targeting the gut microbiota could impact the development of disease in a humanized mouse model of IgAN, the α1KI-CD89Tg mice. Methods Four- and 12-week old mice were divided into two groups to receive either antibiotics or vehicle control. Faecal bacterial load and proteinuria were quantified both at the beginning and at the end of the experiment, when blood, kidneys and intestinal tissue were collected. Serum mouse immunoglobulin G (mIgG) and human immunoglobulin A1 (hIgA1)-containing complexes were quantified. Renal and intestinal tissue were analysed by optical microscopy after haematoxylin and eosin colouration and immunohistochemistry with anti-hIgA and anti-mouse CD11b antibodies. Results Antibiotic treatment efficiently depleted the faecal microbiota, impaired GALT architecture and impacted mouse IgA production. However, while hIgA1 and mIgG serum levels were unchanged, the antibiotic treatment markedly prevented hIgA1 mesangial deposition, glomerular inflammation and the development of proteinuria. This was associated with a significant decrease in circulating hIgA1–mIgG complexes. Notably, final faecal bacterial load strongly correlated with critical clinical and pathophysiological features of IgAN such as proteinuria and hIgA1–mIgG complexes. In addition, treatment with broad-spectrum antibiotics reverted established disease. Conclusions These data support an essential role of the gut microbiota in the generation of mucosa-derived nephrotoxic IgA1 and in IgAN development, opening new avenues for therapeutic approaches in this disease.

Abstract: Background Henoch-Schonlein purpura, more recently renamed immunoglobulin A vasculitis (IgAV), is a systemic vasculitis characterized by IgA deposits. The current markers used to assess IgAV inaccurately evaluate the risk of nephritis occurrence and its long-term outcomes. The current study assessed biomarkers of nephritis outcomes. Methods This French multicentre prospective study enrolled 85 adult patients at the time of disease onset. Patients were assessed for clinical and biological parameters and re-examined after 1 year. Immunoglobulins, cytokines, IgA glycosylation, IgA complexes and neutrophil gelatinase-associated lipocalin (NGAL) concentrations were assessed in blood and urine. Results We identified 60 patients with IgAV-related nephritis (IgAV-N) and 25 patients without nephritis (IgAV-woN). At the time of inclusion (Day 1), the serum levels of galactose-deficient IgA1 (Gd-IgA1) and urinary concentrations of IgA, IgG, IgM, NGAL, interleukin (IL)-1β, IL-6, IL-8, IL-10, IgA-IgG and IgA-sCD89 complexes were higher in the IgAV-N patients than in the IgAV-woN patients (P

Abstract: We read with great interest the European League Against Rheumatism/European Renal Association–European Dialysis and Transplant Association guidelines for the management of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV).1 We strongly support the recommendation of performing a renal biopsy whenever a renal involvement is suspected as the only organ-threatening or life-threatening manifestation. Indeed, we came across several cases of different diseases presenting as AAV which support this recommendation, as exemplified below. An 18-year-old woman self-presented to the emergency department (ED) with abdominal pain, diarrhoea, gross …

Abstract: French Thrombotic Microangiopathies Reference Centre; International audience; Chronic kidney disease (CKD) is a frequent and serious complication of atypical haemolytic uremic syndrome (aHUS). We aimed to develop a simple accurate model to predict the risk of renal dysfunction in aHUS based on clinical and biological features available at hospital admission. Renal function at 1-year follow-up, based on an estimated glomerular filtration rate < 60mL/min/1.73m 2 as assessed by the Modification of Diet in Renal Disease equation, was used as an indicator of significant CKD. Prospectively collected data from a cohort of 156 aHUS patients who did not receive eculizumab were used to identify predictors of CKD. Covariates associated with renal impairment were identified by multivariate analysis. The model performance was assessed and a scoring system for clinical practice was constructed from the regression coefficient. Multivariate analyses identified three predictors of CKD: a high serum creatinine level, a high mean arterial pressure and a mildly decreased platelet count. The prognostic model had a good discriminative ability (area under the curve = .84). The scoring system ranged from 0 to 5, with corresponding risks of CKD ranging from 18% to 100%. This model accurately predicts development of 1-year CKD in patients with aHUS using clinical and biological features available on admission. After further validation , this model may assist in clinical decision making.

Abstract: IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide and has significant morbidity and mortality as 20–40% of patients progress to end-stage renal disease (ESRD) within 20 years after disease onset. We aimed to gain insight into the molecular mechanisms involved in IgAN progression. A systematic evaluation of renal biopsy specimens from IgAN patients revealed that the MAPK/ERK signaling pathway was activated in mesangial areas of patients presenting with >1 g/day proteinuria and elevated blood pressure, but was absent in biopsy specimens from IgAN patients with modest proteinuria (

Abstract: Renal transplants remain a medical challenge, because the parameters governing allograft outcome are incompletely identified. Here, we investigated the role of serum iron in the sterile inflammation that follows kidney ischemia-reperfusion injury. In a retrospective cohort study of renal allograft recipients (n=169), increased baseline levels of serum ferritin reliably predicted a positive outcome for allografts, particularly in elderly patients. In mice, systemic iron overload protected against renal ischemia-reperfusion injury-associated sterile inflammation. Furthermore, chronic iron injection in mice prevented macrophage recruitment after inflammatory stimuli. Macrophages cultured in high-iron conditions had reduced responses to Toll-like receptor-2, -3, and -4 agonists, which associated with decreased reactive oxygen species production, increased nuclear localization of the NRF2 transcription factor, increased expression of the NRF2-related antioxidant response genes, and limited NF-κB and proinflammatory signaling. In macrophage-depleted animals, the infusion of macrophages cultured in high-iron conditions did not reconstitute AKI after ischemia-reperfusion, whereas macrophages cultured in physiologic iron conditions did. These findings identify serum iron as a critical protective factor in renal allograft outcome. Increasing serum iron levels in patients may thus improve prognosis of renal transplants.

Abstract: Strait et al. described a novel mouse model of cryoglobulinaemia by challenging mice deficient in the immunoglobulin (Ig)G1 subclass (γ1(-) mice) with goat anti-mouse IgD [5]. The phenotype of wild-type mice was not remarkable, whereas γ1(-) mice developed IgG3 anti-goat IgG cryoglobulins as well as severe and lethal glomerulonephritis. Renal phenotype could not be rescued in γ1(-) mice by the deletion of C3, fragment crystalline γ receptor (FcγR) or J chain. On the other hand, early injection of IgG1, IgG2a or IgG2b inhibited the pathogenic effects of IgG3 in an antigen-dependent manner even in the absence of the FcγRIIb, an anti-inflammatory receptor. The authors concluded that the pathogenic role of IgG3 and the protective characteristic of IgG1 in this model were not explained by their abilities to bind to FcRs or effector molecules but are rather due to structural discrepancies enhancing the precipitation properties/solubility of IgG3/IgG1-containing immune complexes. The present article aims to discuss the current knowledge on IgG biology and the properties of IgGs explaining their differential propensity to acquire cryoglobulin activity.

Abstract: NephroTest study group; International audience; BackgroundSerum creatine kinase (sCK) reflects CK activity from striated skeletal muscle. Muscle wasting is a risk factor for mortality in patients with chronic kidney disease (CKD). The aim of this study is to evaluate whether sCK is a predictor of mortality and end-stage renal disease (ESRD) in a CKD population.MethodsWe included 1801 non-dialysis-dependent CKD patients from the NephroTest cohort. We used time-fixed and time-dependent cause-specific Cox models to estimate hazard ratios (HRs) for the risk of death and for the risk of ESRD associated with gender-specific sCK tertiles.ResultsHigher sCK level at baseline was associated with a lower age, a higher body mass index, and a higher level of 24 h urinary creatinine excretion, serum albumin and prealbumin (p

Abstract: NephroTest Study Group; International audience; BACKGROUND:Little is known about muscle mass loss in early stage chronic kidney disease (CKD). We used 24-hour urinary creatinine excretion rate to assess determinants of muscle mass and its evolution with kidney function decline. We also described the range of urinary creatinine concentration in this population.METHODS:We included 1072 men and 537 women with non-dialysis CKD stages 1 to 5, all of them with repeated measurements of glomerular filtration rate (mGFR) by (51)Cr-EDTA renal clearance and several nutritional markers. In those with stage 1 to 4 at baseline, we used a mixed model to study factors associated with urinary creatinine excretion rate and its change over time.RESULTS:Baseline mean urinary creatinine excretion decreased from 15.3 ± 3.1 to 12.1 ± 3.3 mmol/24 h (0.20 ± 0.03 to 0.15 ± 0.04 mmol/kg/24 h) in men, with mGFR falling from ≥ 60 to

Abstract: on behalf of the NephroTest Study Group; International audience; The metabolism of hepcidin is profoundly modified in chronic kidney disease (CKD). We investigated its relation to iron disorders, inflammation and hemoglobin (Hb) level in 199 non-dialyzed, non-transplanted patients with CKD stages 1–5. All had their glomerular filtration rate measured by 51 Cr-EDTA renal clearance (mGFR), as well as measurements of iron markers including hepcidin and of erythropoietin (EPO). Hepcidin varied from 0.2 to 193 ng/mL. The median increased from 23.3 ng/ mL [8.8–28.7] to 36.1 ng/mL [14.1–92.3] when mGFR decreased from $60 to ,15 mL/min/1.73 m 2 (p = 0.02). Patients with absolute iron deficiency (transferrin saturation (TSAT) ,20% and ferritin ,40 ng/mL) had the lowest hepcidin levels (5.0 ng/ mL [0.7–11.7]), and those with a normal iron profile (TSAT $20% and ferritin $40), the highest (34.5 ng/mL [23.7–51.6]). In multivariate analysis, absolute iron deficiency was associated with lower hepcidin values, and inflammation combined with a normal or functional iron profile with higher values, independent of other determinants of hepcidin concentration, including EPO, mGFR, and albuminemia. The hepcidin level, although it rose overall when mGFR declined, collapsed in patients with absolute iron deficiency. There was a significant interaction with iron status in the association between Hb and hepcidin. Except in absolute iron deficiency, hepcidin's negative association with Hb level indicates that it is not down-regulated in CKD anemia.

Abstract: Microscopic polyangiitis, granulomatosis with polyangiitis, Churg-Strauss syndrome and focal necrotizing glomerulonephritis are severe systemic vasculitides associated with circulating antineutrophil cytoplasmic antibodies (ANCA). Several studies reported that some malignancies can develop in these patients during follow-up, but few studies have considered the association and role of pre-existing cancers, at least in a fraction of patients. Herein, we report five patients with ANCA-associated diseases who had associated lung carcinomas or were diagnosed within 2 years after vasculitis onset. We discuss the putative role of tumor antigen in driving the auto-immune response.

Abstract: Background The association between sarcoidosis and glomerular diseases has not been extensively investigated in a large series and the potential features of this uncommon association remain to be determined. Methods We retrospectively identified 26 patients with biopsy-proven glomerular lesions that occurred in a sarcoidosis context. Potential remission of glomerular disease and sarcoidosis under specific treatment (steroid and/or immunosuppressive agents) was recorded for all patients. Demographic, clinical and biological characteristics were assessed at the time of kidney biopsy for each patient. Therapeutic data were analyzed for all patients. Results Glomerular disease occurred after the diagnosis of sarcoidosis in 11 of 26 cases (42%) (mean delay of 9.7 years). In six patients (23%), the glomerulopathy preceded the sarcoidosis diagnosis (mean delay 8 years). In the last nine patients (35%), both conditions occurred simultaneously. The most frequent glomerular disease occurring in sarcoidosis patients was membranous nephropathy in eleven cases. Other glomerular lesions included IgA nephropathy in six cases, focal segmental glomerulosclerosis in four patients, minimal change nephrotic syndrome for three patients and proliferative lupus nephritis in two patients. Granulomatous interstitial nephritis was associated with glomerular disease in six patients and was exclusively found in patients in whom the both disease occurred simultaneously. In nine patients with simultaneous glomerular and sarcoidosis diseases, we observed a strong dissociation between glomerular disease and sarcoidosis in terms of steroid responsiveness. At the end of the follow-up (mean of 8.4 years), six patients had reached end-stage renal disease and three patients had died. Conclusions A wide spectrum of glomerular lesions is associated with sarcoidosis. The close temporal relationship observed in some patients suggests common causative molecular mechanisms of glomerular injury but complete remission of both diseases in response to exclusive steroid therapy is infrequent.

Abstract: International audience; Early posttransplant steroid withdrawal may increase the risk of acute rejection and the occurrence of subclinical acute rejection (SCAR). We assessed the feasibility and safety of early steroid withdrawal in low-risk patients receiving cyclosporine A (CsA) and the impact of optimization of mycophenolic acid exposure on steroid withdrawal success. De novo, low-immunological risk kidney recipients received an anti-interleukin-2-receptor-α antibody induction, a short course of 7 days of corticosteroids, and CsA with 2-hr postdose concentration monitoring. They were randomized to adjusted dose (AD) of mycophenolate mofetil (MMF) using therapeutic drug monitoring (TDM) or a fixed-dose (FD) regimen. MMF 3 g was initiated posttransplant and then adjusted starting at week 2 to a 0 to 12 hr area under the concentration time curve of 40 mg · h/L versus 2 g daily, respectively. The primary endpoint was a composite of the proportion of patients experiencing biopsy-proven acute rejection (BPAR) and those with SCAR identified on the 3-month protocol biopsy. Among 247 analyzed patients, only 22 in the AD group and 17 in the FD group experienced BPAR or SCAR (P=0.46). The rate of SCAR was low: 4% (AD) and 2.5% (FD). No between-group difference in the incidence of BPAR was observed. TDM yielded MMF doses ranging from 1 to 4 g/d and significantly reduced interpatient variability at weeks 26 and 52 in the AD group. In low-immunological risk kidney recipients, MMF combined with CsA allows early corticosteroid discontinuation with good tolerability. In this group of patients, TDM of MMF does not improve clinical outcome.
