Abstract Background Infection-related glomerulonephritis with IgA deposits (IRGN-IgA) is a rare disease but it is increasingly reported in the literature. Data regarding epidemiology and outcome are lacking, especially in Europe. We aimed to assess the clinical, pathologic and outcome data of IRGN-IgA. Methods Clinical and outcome data from patients from 11 French centers over the 2007–2017 period were collected retrospectively. We reviewed pathologic patterns and immunofluorescence of renal biopsies and evaluated C4d expression in IRGN-IgA. We analyzed the correlation between histological presentation and outcome. Results Twenty-seven patients (23 men, mean age: 62 ± 15 years) were included. Twenty-one (78%) had Staphylococcus aureus infection and twelve (44%) were diabetic. At the time of biopsy, 95.2% had haematuria, 48.1% had a serum creatinine level of > 4 mg/dL, and 16% had hypocomplementemia. The most common pathologic presentation included mesangial (88.9%) and endocapillary proliferative glomerulonephritis (88.9%) with interstitial fibrosis and tubular atrophy (IF/TA) (85.1%). Diffuse and global glomerular C4d expression was found in 17.8%, mostly in biopsies with acute or subacute patterns, and was associated with a short delay between infection and renal biopsy compared to segmental and focal staining. After median follow-up of 13.2 months, 23.1% died, 46.2% had persistent renal dysfunction and 15.4% reached end-stage renal disease. Renal outcome was correlated to IF/TA severity. Conclusions Infection-related glomerulonephritis with IgA deposits is usually associated with Staphylococcus infections and mainly affects adult men. This entity has a poor prognosis which is correlated to interstitial fibrosis and tubular atrophy severity.

IntroductionThe “Renal Risk Score” (RRS) and the histopathological classification have been proposed to predict the risk of end-stage kidney disease (ESKD) in ANCA-associated glomerulonephritis (ANCA-GN). Besides, factors associated with kidney function recovery after ANCA-GN onset remain to be more extensively studied. In the present study, we analyzed the value of the RRS and of the histopathological classification for ESKD prediction. Next, we analyzed factors associated with eGFR change within the first 2 years following ANCA-GN diagnosis.Materials and MethodsWe included patients from the Maine–Anjou ANCA-associated vasculitis registry with at least 6 months of follow-up. The values of ANCA-GN, histopathological classification, and RRS, and the factors associated with eGFR variations between ANCA-GN diagnosis and 2 years of follow-up were assessed.ResultsThe predictive values of the histopathological classification and RRS were analyzed in 123 patients. After a median follow-up of 42 months, 33.3% patients developed ESKD. The predictive value of RRS for ESKD was greater than that of the histopathological classification. Determinants of eGFR variation were assessed in 80/123 patients with complete eGFR measurement. The median eGFR increased from ANCA-GN diagnosis to month 6 and stabilized thereafter. The only factor associated with eGFR variation in our study was eGFR at ANCA-GN diagnosis, with higher eGFR at diagnosis being associated with eGFR loss (p

Background: Thrombotic microangiopathies (TMAs) are highly suspected in patients showing mechanical hemolytic anemia, thrombocytopenia, and haptoglobin consumption. Primary [thrombotic thrombocytopenic purpura (TTP) and atypical hemolytic uremic syndrome] and secondary TMA are considered. Even if ADAMTS13 measurements and alternative complement pathway explorations have greatly improved the ability to identify primary TMA, their diagnosis remains difficult, and their frequency relative to that of secondary TMA is undetermined. The objectives of the present study were, therefore, to describe the etiologies, management, and the outcomes of patients presenting with TMA in real-life clinical practice.Methods: We conducted a retrospective study between 01/01/2008 and 31/12/2018 that included all consecutive patients presenting with biological TMA syndrome at admission or developing during hospitalization. Patients were identified from the laboratory databases, and their medical files were reviewed to confirm TMA diagnosis, to determine etiology, and to analyze their therapeutic management and outcomes.Results: During this period, 239 patients with a full TMA biological syndrome were identified, and the TMA diagnosis was finally confirmed in 216 (90.4%) after the cases were reviewed. Primary TMAs (thrombotic thrombocytopenic purpura or atypical hemolytic uremic syndrome) were diagnosed in 20 of 216 patients (9.3%). Typical HUS was diagnosed in eight patients (3.7%), and the most frequent secondary TMAs were HELLP syndrome (79/216, 36.6%) and active malignancies (30/219, 13.9%). ADAMTS13 measurements and alternative complement pathway analyses were performed in a minority of patients. Multiple factors identified as TMA triggers were present in most patients, in 55% of patients with primary TMA, vs. 44.7% of patients with secondary TMA (p = 0.377). Death occurred in 57 patients (23.4%) during follow-up, and dialysis was required in 51 patients (23.6%). Active malignancies [odds ratio (OR) 13.7], transplantation (OR 4.43), male sex (OR 2.89), and older age (OR 1.07) were significantly associated with death.Conclusion: Secondary TMAs represent many TMA causes in patients presenting a full TMA biological syndrome during routine clinical practice. Multiple factors favoring TMA are present in about half of primary or secondary TMA. ADAMTS13 and complement pathway were poorly explored in our cohort. The risk of death is particularly high in patients with malignancies as compared with patients with other TMA.

Background and Aims Lymphopenia is commonly observed in various autoimmune diseases, such as systemic lupus erythematosus, where it has been associated with disease activity or prognosis. However, in ANCA-associated vasculitis (AAV) only few, small-scale studies have been targeted to this issue. Research has not yet focused on ANCA-glomerulonephritis (ANCA-GN) patients. Thus, the aim of this study was to analyze the association between lymphocyte counts and outcomes in a large cohort of ANCA-GN patients. Method We used the Maine-Anjou AAV registry that retrospectively gathers data on consecutive patients affected by AAV in four French Nephrology Centers, recorded since January 2000. We analyzed clinical, biological, and histological data at diagnosis of ANCA-GN. Biological data, including lymphocyte counts, were collected before the administration of any immunosuppressive treatment. Risk factors for end-stage kidney disease (ESKD) were analyzed. Event-free survival was also assessed. Results Among the 145 patients included in the study, 53 (37%) patients presented with lymphopenia at ANCA-GN diagnosis. Lymphopenic patients were older (72 [63–79] vs 66 [56–73] years old, p = 0.010), had a lower renal function at baseline (eGFR 13 mL/min vs 26 mL/min, p = 0.002), and a higher proteinuria (1.86 [1.21–3.52] g/g vs 1.30 [0.75–2.65] g/g, p = 0.042). There was a trend for a higher BVAS (18 [14–22] vs 15 [12–20], p = 0.076) in lymphopenic patients. Therapeutic management between the two groups was similar. There was no difference in relapse rate between the two groups but lymphopenic patients were more likely to require kidney replacement therapy (51% vs 25%, p = 0.003) and were more likely to die (34% vs 17%, p = 0.039). Lymphopenia was correlated with histological lesions and especially with the percentage of sclerotic glomeruli (p = 0.0027). ESKD-free survival and overall survival were lower in lymphopenic patients (p < 0.0001 and 0.0051 respectively). In multivariate Cox analysis, lymphopenia, but not death, was an independent risk factor for ESKD (HR 4.47 (95% confidence interval: [2.06–9.72], p < 0.001). Conclusion Lymphopenia correlates with severity of ANCA-GN at diagnosis and predicts poor renal outcome. In this view, lymphopenia could be used as a simple and cost-effective biomarker to assess renal prognosis at ANCA-GN diagnosis.

The aim of this study was to estimate the incidence of COVID-19 disease in the French national population of dialysis patients, their course of illness and to identify the risk factors associated with mortality. Our study included all patients on dialysis recorded in the French REIN Registry in April 2020. Clinical characteristics at last follow-up and the evolution of COVID-19 illness severity over time were recorded for diagnosed cases (either suspicious clinical symptoms, characteristic signs on the chest scan or a positive reverse transcription polymerase chain reaction) for SARS-CoV-2. A total of 1,621 infected patients were reported on the REIN registry from March 16th, 2020 to May 4th, 2020. Of these, 344 died. The prevalence of COVID-19 patients varied from less than 1% to 10% between regions. The probability of being a case was higher in males, patients with diabetes, those in need of assistance for transfer or treated at a self-care unit. Dialysis at home was associated with a lower probability of being infected as was being a smoker, a former smoker, having an active malignancy, or peripheral vascular disease. Mortality in diagnosed cases (21%) was associated with the same causes as in the general population. Higher age, hypoalbuminemia and the presence of an ischemic heart disease were statistically independently associated with a higher risk of death. Being treated at a selfcare unit was associated with a lower risk. Thus, our study showed a relatively low frequency of COVID-19 among dialysis patients contrary to what might have been assumed., Graphical abstract

(1) Introduction: The incidence of venous thromboembolisms (VTE) has not been extensively analyzed in patients with antineutrophil cytoplasmic antibody (ANCA)-glomerulonephritis (ANCA-GN). Thus, the aim of the present study was to assess the frequency and the risk factors of VTE in patients with ANCA-GN. (2) Methods: Patients from the Maine-Anjou ANCA-associated vasculitis (AAV) registry with a biopsy showing pauci-immune glomerulonephritis were included. VTE events, site, and interval from AAV diagnosis were analyzed. (3) Results: 133 patients fulfilled the inclusion criteria of the study and were analyzed. VTE episodes were diagnosed in 23/133 (17.3%) patients at a median delay of 3 months from ANCA-GN diagnosis. Patients with VTE had lower serum albumin (p = 0.040), were less frequently on statin therapy (p = 0.009) and had less frequently proteinase-3 (PR3)-ANCAs (p = 0.078). Univariate analysis identified higher age (p = 0.022), lower serum albumin (p = 0.030), lack of statin therapy (p = 0.009), and rituximab treatment (p = 0.018) as significant risk factors of VTE. In multivariate analysis, only lack of statin therapy (HR 4.873, p = 0.042) was significantly associated with VTE. (4) Conclusion: Patients with ANCA-GN are at high risk of VTE, especially within the first months following AAV diagnosis. Our results suggest that statin therapy is associated with a lower risk of VTE in ANCA-GN patients.

Background: Thrombotic microangiopathies (TMAs) are highly suspected in patients showing mechanical hemolytic anemia, thrombocytopenia, and haptoglobin consumption. Primary [thrombotic thrombocytopenic purpura (TTP) and atypical hemolytic uremic syndrome] and secondary TMA are considered. Even if ADAMTS13 measurements and alternative complement pathway explorations have greatly improved the ability to identify primary TMA, their diagnosis remains difficult, and their frequency relative to that of secondary TMA is undetermined. The objectives of the present study were, therefore, to describe the etiologies, management, and the outcomes of patients presenting with TMA in real-life clinical practice.Methods: We conducted a retrospective study between 01/01/2008 and 31/12/2018 that included all consecutive patients presenting with biological TMA syndrome at admission or developing during hospitalization. Patients were identified from the laboratory databases, and their medical files were reviewed to confirm TMA diagnosis, to determine etiology, and to analyze their therapeutic management and outcomes.Results: During this period, 239 patients with a full TMA biological syndrome were identified, and the TMA diagnosis was finally confirmed in 216 (90.4%) after the cases were reviewed. Primary TMAs (thrombotic thrombocytopenic purpura or atypical hemolytic uremic syndrome) were diagnosed in 20 of 216 patients (9.3%). Typical HUS was diagnosed in eight patients (3.7%), and the most frequent secondary TMAs were HELLP syndrome (79/216, 36.6%) and active malignancies (30/219, 13.9%). ADAMTS13 measurements and alternative complement pathway analyses were performed in a minority of patients. Multiple factors identified as TMA triggers were present in most patients, in 55% of patients with primary TMA, vs. 44.7% of patients with secondary TMA (p = 0.377). Death occurred in 57 patients (23.4%) during follow-up, and dialysis was required in 51 patients (23.6%). Active malignancies [odds ratio (OR) 13.7], transplantation (OR 4.43), male sex (OR 2.89), and older age (OR 1.07) were significantly associated with death.Conclusion: Secondary TMAs represent many TMA causes in patients presenting a full TMA biological syndrome during routine clinical practice. Multiple factors favoring TMA are present in about half of primary or secondary TMA. ADAMTS13 and complement pathway were poorly explored in our cohort. The risk of death is particularly high in patients with malignancies as compared with patients with other TMA.

Background Infection-related glomerulonephritis with IgA deposits (IRGN-IgA) is a rare disease but it is increasingly reported in the literature. Data regarding epidemiology and outcome are lacking, especially in Europe. We aimed to assess the clinical, pathologic and outcome data of IRGN-IgA. Methods Clinical and outcome data from patients from 11 French centers over the 2007–2017 period were collected retrospectively. We reviewed pathologic patterns and immunofluorescence of renal biopsies and evaluated C4d expression in IRGN-IgA. We analyzed the correlation between histological presentation and outcome. Results Twenty-seven patients (23 men, mean age: 62 ± 15 years) were included. Twenty-one (78%) had Staphylococcus aureus infection and twelve (44%) were diabetic. At the time of biopsy, 95.2% had haematuria, 48.1% had a serum creatinine level of > 4 mg/dL, and 16% had hypocomplementemia. The most common pathologic presentation included mesangial (88.9%) and endocapillary proliferative glomerulonephritis (88.9%) with interstitial fibrosis and tubular atrophy (IF/TA) (85.1%). Diffuse and global glomerular C4d expression was found in 17.8%, mostly in biopsies with acute or subacute patterns, and was associated with a short delay between infection and renal biopsy compared to segmental and focal staining. After median follow-up of 13.2 months, 23.1% died, 46.2% had persistent renal dysfunction and 15.4% reached end-stage renal disease. Renal outcome was correlated to IF/TA severity. Conclusions Infection-related glomerulonephritis with IgA deposits is usually associated with Staphylococcus infections and mainly affects adult men. This entity has a poor prognosis which is correlated to interstitial fibrosis and tubular atrophy severity.

International audience; Purpose: Data regarding the long-term outcome of very elderly (VE) patients undergoing renal biopsy (RB) are lacking. The objective of this study was to analyse the outcome of VE patients undergoing RB.Methods: All patients over 65 years that underwent native RB between 2004 and 2016 in our center were included. Among the 206 included patients, those over 80 years (VE, 46 patients) were analysed and compared to those aged 65-80 years (160 patients). The outcomes of the VE group were analysed.Results: Baseline characteristics, renal presentation, safety of RB and RB-related diagnosis were not different between VE patients and 65-80-year-old patients. Survival of VE patients was 73.1, 50.6 and 21.8% at 2, 4 and 6 years after RB, significantly poorer than those of 65-80-year-old group. Early death (< 1 year) occurred in 10 VE patients, was associated with a higher proteinuria-to-creatininuria ratio and tended to be associated with a more frequent dialysis need at RB. Of the 46 VE patients, 31 (67.4%) were diagnosed with a potentially reversible kidney disease, of whom 17 (40%) were started on immunosuppressive regimens. Survival of patients with a reversible kidney disease tended to be better than those with other diseases.Conclusion: RB appears as a safe and valuable procedure to assess diagnosis of kidney disease in VE patients. Our data suggest that RB is critical for the identification and treatment decision of patients with potentially reversible diseases and may translate in clinical improvement.

Background Infection-related glomerulonephritis with IgA deposits (IRGN-IgA) is being more widely recognized but the precise epidemiology and outcome is lacking, particularly in Europe. We aimed to assess clinical, pathologic and outcome data of IRGN-IgA. Methods Clinical and outcome data from patients from 11 French centers over the 2007-2017 period were retrospectively collected. We reviewed pathologic patterns and immunofluorescence of renal biopsies and evaluated C4d expression in IRGN-IgA. We analyzed correlation between histological presentation and outcome using the Chi square test (qualitative data) and Kruskal-Wallis test (quantitative data). Results Twenty-seven patients (23 men, mean age: 62 ± 15 years) were included. Most of them had a Staphylococcus aureus infection (77.8%) and 44.4% were diabetic. At the time of biopsy, 95.2% had haematuria, 48.1% had a serum creatinine >4 mg/dL, and 16% had a hypocomplementemia.

After a median follow-up of 13.2 months, 23.1% died, 46.2% had persistent renal dysfunction and 15.4% reached end-stage renal disease. Renal outcome was correlated to IF/TA severity. Conclusions Infection-related glomerulonephritis with IgA deposits is usually associated with Staphyloccus infections and mainly affects adult men. This entity has a poor prognosis which is correlated to interstitial fibrosis and tubular atrophy severity.

International audience; INTRODUCTION: Therapeutic plasma exchange (TPE) can be proposed in the treatment of chronic dysimmune peripheral neuropathies (CDPN). Actual guidelines are however based on few studies, and indications and protocols still remain to be clarified. We conducted a 10-year retrospective study in order to assess the effectiveness and tolerance of TPE in CDPN.METHODS: All patients treated for CDPN with TPE from October 2006 to March 2016 in the university hospital of Angers were included. Patients were considered responders when they presented a clinical improvement substantial enough to continue the treatment. The Hughes functional grading score was also determined for each patient before and after TPE initiation.RESULTS: Among the 206 patients who received TPE during the study period, 30 (14.6%) met the diagnostic criteria of CDPN. Four of the five paraprotein neuropathies (PPN) patients (80%) and 8 of the 11 chronic inflammatory demyelinating polyneuropathies (CIDP) patients (72.7%) were responders, with a significant improvement of the Hughes score for the latter (P = 0.013). None of the three Lewis-Sumner and the two POEMS patients showed substantial improvement. Six of the nine anti-MAG neuropathy patients (66.7%) responded to treatment, with a trend towards improvement of the Hughes score (P = 0.072).CONCLUSION: TPE appears to be effective in CIDP and PPN, and ineffective in Lewis-Sumner and POEMS syndromes. Interestingly, anti-MAG neuropathy patients showed a good rate of response to TPE. Regarding these preliminary results, a randomized trial would be very worthwhile in this disease for which there is no evidence based treatment to date.

International audience; Background and objectives: The overlap between antineutrophil cytoplasmic antibody (ANCA) associated glomerulonephritis (ANCA-GN) and connective tissue diseases (CTD) has been reported mainly as case series in the literature. Frequency of this association, as well as presentation and outcomes are unknown. Materials and Methods: Patients from the Maine-Anjou ANCA-associated vasculitides (AAV) registry with ANCA-GN diagnosed between 01/01/2000 and 01/01/2018, ANCA positivity, and at least six months of follow-up, were included. Results: 106 out of 142 patients fulfilled the inclusion criteria and were analyzed. CTD was present at ANCA-GN diagnosis in 16 (15.1%) patients. The most common CTD were rheumatoid arthritis, Sjogren syndrome and systemic sclerosis. Compared to the control group, females were more represented in the CTD group (75%, p = 0.001). Renal presentation was comparable between groups, including the pathological analysis of renal biopsies. Patients of CTD group presented a higher rate of non-renal relapse (25% versus 7.7%, p = 0.037), and experienced more frequently a venous thrombotic event (31.2% versus 10%, p = 0.021). No difference between groups was observed according to major outcomes. Conclusion: Association between CTD and ANCA-GN is not a rare condition and predominantly affects females. While AAV presentation is not significantly different, CTD patients experience more frequently non-renal relapse and venous thrombotic events.

Background Adult Henoch-Schonlein purpura (HSP) has been associated with poor outcome and end-stage renal disease in >20% of cases. Although the benefit of adding another immunosuppressant to steroids in severe adult HSP has not been shown, the benefit of plasma exchange (PE) therapy has been poorly evaluated. Study Design Case series. Setting & Participants 11 consecutive patients with severe and newly diagnosed HSP since 1988 who were treated with steroids and PE. Outcome & Measurement Patients' characteristics and outcome were analyzed. Birmingham Vasculitis Activity Score (BVAS), estimated glomerular filtration rate (eGFR), and proteinuria were measured at baseline, at the end of PE treatment, at months 6 and 12, and at the last visit. Side effects of corticoid treatment and PE were recorded. Results 11 patients were identified in 1988-2010. Patients received intravenous corticoid pulses in 64% of cases, followed by oral prednisone for a median of 6.6 months. They received a median of 12 PE sessions. BVAS, eGFR, and proteinuria improved significantly between baseline and the last PE at a median of 2 months. PE sessions were well tolerated, except in one patient who developed central catheter–associated septicemia. One patient required dialysis therapy 15 days after HSP diagnosis and did not recover kidney function. At the last medical evaluation at a mean follow-up of 6 years, median eGFR and proteinuria were 83 ± 22 mL/min/1.73 m 2 and protein excretion of 140 ± 10 mg/d, respectively. 3 women had pregnancy without complications. Limitations This case series did not have a control group. Conclusions The combination of PE and corticoid therapy in severe forms of HSP was associated with fast improvement and good long-term outcome.

Nephrology - Abstract
Resume Le retour en dialyse apres echec de transplantation est un probleme emergent dans les centres de dialyse. L’objectif de cette etude est de determiner les conditions de prise en charge initiale en dialyse des patients en echec de greffe et leur devenir a court terme en epuration extrarenale. Patients et methodes Il s’agit d’une etude retrospective portant sur des patients ayant recu une greffe renale dans le centre regional de reference et retournant en dialyse apres plus de six mois en transplantation dans un centre de la region pendant la periode du 31 octobre 1986 au 03 mars 2004. La periode de suivi est de un an pour tous les patients. Resultats Parmi les 600 patients transplantes pendant la periode d’etude, 92 sont retournes en dialyse dont 69 apres une duree en transplantation de plus de six mois. A l’initiation de la dialyse la clairance moyenne de la creatinine etait de 13 ± 5 mL par minute. L’albuminemie moyenne etait de 34 ± 6 g/L et l’hemoglobinemie moyenne etait de 80,7 ± 10,7 g/L. La dialyse a ete debutee dans un contexte d’urgence pour 39 sur 57 (50 %) patients et sur catheter pour 14 sur 58 (25 %) patients. L’hemodialyse etait la methode de choix pour 59 sur 69 (85 %) patients, le retour dans la methode d’origine etait moins frequent chez les patients traites par la dialyse peritoneale que chez les patients traites par hemodialyse (7/13 versus 49/52 ; p Conclusion Malgre un suivi nephrologique regulier les patients en echec de greffe debutent frequemment la dialyse de facon non planifiee et en urgence. Une prise en charge plus precoce en dialyse des patients en echec de greffe est probablement necessaire.

Introduction Les echanges plasmatiques (EP) peuvent etre proposes comme traitement de certaines Neuropathies Peripheriques Dysimmunitaires Chroniques (NPDC). Toutefois, plusieurs points concernant leur utilisation dans ces indications restent encore a preciser. Objectifs Nous avons mene une etude retrospective de 10 ans au CHU d’Angers afin d’evaluer l’efficacite et la tolerance des echanges plasmatiques dans le traitement des NPDC. Patients et methodes Les dossiers des patients traites par EP entre 2006 et 2016 au CHU d’Angers ont ete etudies, tous les patients traites pour une NPDC ont ete inclus. Les donnees cliniques et les procedures d’echange ont ete analysees. La reponse aux EP a ete evaluee en definissant 2 categories de patients « repondeurs » et « non repondeurs » en fonction de l’evolution clinique et de la decision de poursuivre ou non le traitement. Les scores cliniques de Hughes calcules avant et apres initiation des echanges pour chaque patient ont egalement ete compares. Resultats Parmi les 206 patients traites par EP, 30 l’ont ete pour une NPDC. Huit des 11 patients (73 %) traites pour une PIDC ont repondu aux EP, avec une amelioration significative du score Hughes (p = 0,01). Quatre des 5 patients (80 %) atteints de neuropathie dysglobulinemique et 6 des 9 patients (67 %) atteints de neuropathie a anti-MAG ont repondu aux EP avec pour les seconds une tendance a l’amelioration du score Hughes (p = 0,07). Aucun des 5 patients atteints d’un Lewis-Sumner ou d’un POEMS n’ont repondu aux EP. Discussion Les taux de reponse des patients traites pour une PIDC et une neuropathie dysglobulinemique sont similaires a ceux des essais cliniques ayant valide l’utilisation des EP dans ces deux indications. Les deux tiers des patients atteints de neuropathie a anti-MAG ont repondu traitement ; a notre connaissance aucune etude n’a a ce jour evalue l’efficacite des EP dans cette indication. Les EP semblent peu efficaces dans le Lewis-Sumner et le POEMS. Conclusion L’efficacite des EP observee chez les patients traites pour une neuropathie a anticorps anti-MAG semble prometteuse, des essais cliniques complementaires sont necessaires pour conforter ces premiers resultats.

International audience; BACKGROUND: Atypical hemolytic uremic syndrome (aHUS) is a devastating form of renal thrombotic microangiopathy. Despite plasma exchange, the standard treatment of aHUS for decades, the renal prognosis for patients with aHUS has remained poor. We assessed the off-trial use of eculizumab in adult patients with aHUS affecting the native kidneys.STUDY DESIGN: A retrospective study was conducted. aHUS was defined as the presence of 3 or more of the following: acute kidney injury (serum creatinine >1.4 mg/dL [120 μmol/L]), mechanical hemolytic anemia, thrombocytopenia, and the presence of thrombotic microangiopathy features in a kidney biopsy specimen. Patients who had received 4 or more weekly 900-mg infusions of eculizumab were included.SETTING & PARTICIPANTS: 19 patients were identified through a query sent to all French nephrology centers.OUTCOMES & MEASUREMENTS: Evolution of kidney function, hemolysis, and thrombocytopenia after the initiation of eculizumab therapy.RESULTS: All patients had acute kidney injury (serum creatinine range, 2.2-17.0 mg/dL) and 12 required hemodialysis. Thirteen patients carried a mutation in 1 complement gene and 1 had anti-factor H antibodies. For first-line therapy, 16 patients underwent plasma exchange and 3 patients received eculizumab. Median time between aHUS onset and eculizumab therapy initiation was 6 (range, 1-60) days and median time to platelet count normalization after eculizumab therapy initiation was 6 (range, 2-42) days. At the 3-month follow-up, 4 patients still required dialysis, 8 had non-dialysis-dependent chronic kidney disease, and 7 had normalized kidney function. At last follow-up (range, 4-22 months), 3 patients remained dialysis dependent, 7 had non-dialysis-dependent chronic kidney disease (estimated glomerular filtration rate, 17-55 mL/min/1.73 m(2)), and 9 had normal kidney function. Risks of reaching end-stage renal disease within 3 months and 1 year of aHUS onset were reduced by half in eculizumab-treated patients compared with recent historical controls.LIMITATIONS: Retrospective study and use of historical controls.CONCLUSIONS: Our data indicate that eculizumab improves kidney disease outcome in patients with aHUS.

Drug rash with eosinophilia and systemic symptoms (DRESS syndrome) is a rare and severe drug-induced hypersensitivity syndrome characterized by haematological abnormalities (hypereosinophilia and/or mononucleosis) and multiorgan involvement. Renal failure has been rarely described. We report the case of a 77-year-old female with sulphasalazine-induced DRESS syndrome who improved rapidly on corticosteroid treatment. After prednisone withdrawal, the patient developed renal failure that necessitated a session of haemodialysis. A kidney biopsy showed acute tubulointerstitial nephritis with an intense lymphocytic infiltrate and tubular necrosis. Kidney function normalized after a further 2 weeks of corticosteroid treatment. This is the first histologically proven case of acute tubulointerstitial nephritis in the setting of sulphasalazine-induced DRESS syndrome.

A 26-year-old woman presented to a local community hospital with fever and abdominal pain. Clinical examination showed mild abdominal and bilateral lumbar tenderness. Blood analysis showed C-reactive protein of 401 mg/l, leukocyte count of 15,340/mm3, and serum creatinine of 71 μmol/l. Chest radiograph and abdominal ultrasound were normal. She was diagnosed with pyelonephritis despite negative urinalysis and was discharged. Soon after, her condition worsened with 5 kg weight loss, myalgia, and arthralgia. Two months later, she was readmitted with severe left flank pain. Contrast-enhanced abdominal computed tomography (CT) showed a large subcapsular hematoma surrounding the left kidney (Figure 1). Multiple bilateral intrarenal aneurysms of variable diameter (1–14 mm) were detected during the arterial phase (Figure 1) with the appearance of bunch of grapes. Multiple bilateral wedge-shaped low-attenuation involving cortex and medulla suggesting kidney infarcts were also detected (Supplementary Figure 1 online). Urinalyses showed microscopic hematuria and proteinuria of 0.9 g/24 h. Comprehensive autoimmune including Anti-neutrophil cytoplasmic antibodies (ANCA) research and viral screenings were negatives.

International audience; Blood flow reduction induces inward remodeling of resistance arteries (RAs). This remodeling occurs in ischemic diseases, diabetes and hypertension. Nonetheless, the effect of flow reduction per se, independent of the effect of pressure or metabolic influences, is not well understood in RA. As angiotensin II is involved in the response to flow in RA, we hypothesized that angiotensin II may also be involved in the remodeling induced by a chronic flow reduction. We analyzed the effect of angiotensin I-converting enzyme inhibition (perindopril) and angiotensin II type 1 receptor blockade (candesartan) on inward remodeling induced by blood flow reduction in vivo in rat mesenteric RAs (low flow (LF) arteries). After 1 week, diameter reduction in LF arteries was associated with reduced endothelium-dependent relaxation and lower levels of eNOS expression. Superoxide production and extracellular signal-regulated kinases 1/2 (ERK1/2 phosphorylation were higher in LF than in normal flow arteries. Nevertheless, the absence of eNOS or superoxide level reduction (tempol or apocynin) did not prevent LF remodeling. Perindopril and candesartan prevented inward remodeling in LF arteries. Contractility to angiotensin II was reduced in LF vessels by perindopril, candesartan and the ERK1/2 blocker PD98059. ERK1/2 activation (ratio phospho-ERK/ERK) was higher in LF arteries, and this activation was prevented by perindopril and candesartan. ERK1/2 inhibition in vivo (U0126) prevented LF-induced diameter reduction. Thus, inward remodeling because of blood flow reduction in mesenteric RA depends on unopposed angiotensin II-induced contraction and ERK1/2 activation, independent of superoxide production. These findings might be of importance in the treatment of vascular disorders.

This study was carried out to evaluate dialysis initiation of failed transplant patient and the short-term outcome of these patients on dialysis.We conducted a retrospective study of transplanted patients from one centre returning in dialysis after allograft failure. Those patients were transplanted between 31st October 1986 and 3rd March 2004. Patients who experienced allograft failure after 6 months on transplantation were included in the study.Among 600 transplanted patients, 92 patients restarted dialysis after allograft failure. Of the 92 failed transplant patients, 69 had a graft survival of more than 6 months. The mean glomerular filtration rate at dialysis initiation was 13+/-5mL per minute. At time of dialysis initiation, patients had mean haemoglobin level at 80.7+/-10.7g/L, and mean serum albumin level at 34+/-6g/L. Urgent dialysis was needed for 39 over 57 patients. Fourteen over 58 patients had no vascular access or peritoneal catheter at dialysis initiation. Fifty-six over 69 patients were treated by haemodialysis. Of the 13 patients treated by peritoneal dialysis 7 were on PD before transplantation whereas 49 over 57 haemodialysis patients were treated by haemodialysis before transplant failure (p0.05). Immunosuppressive therapy was stopped during the first year following transplantation failure in 52 over 69 patients and 36 over 69 patients underwent transplantectomy. Thirteen over 56 patients presented a least one cardiovascular events after transplantation failure.Unplanned dialysis initiation is frequent in failed transplant patients, in whom an early dialysis start is probably mandatory.

The glucose side-effects, the main osmotic agent in conventional peritoneal dialysis (PD) solutions, are structural and functional changes of the peritoneal membrane, especially diabetic alterations in the microvasculature. Therefore, hyperpermeability with high small solutes transport and less ultrafiltration necessitates more and more high glucose concentration solutions. Glucose degradation products (PDF) and advanced glycation end-products (AGE) are formed and may induce peritoneal membrane alterations. More biocompatible solutions have to be used with less PDF and physiological pH. Icodextrin containing PD solutions have beneficial effect on sustained ultrafiltration for long dwells in PD, limitating fluid overload common in PD patients above all during peritonitis episodes. Amino acid-based PD solutions contribute to the prevention of malnutrition often observed in the diabetic PD population.
