Clinical and Prognostic Factors in Patients with IgG4-Related Kidney Disease.

BACKGROUND: IgG4-related kidney disease is a major manifestation of IgG4-related disease, a systemic fibroinflammatory disorder. However, the clinical and prognostic kidney-related factors in patients with IgG4-related kidney disease are insufficiently defined. METHODS: We conducted an observational cohort study using data from 35 sites in two European countries. Clinical, biologic, imaging, and histopathologic data; treatment modalities; and outcomes were collected from medical records. Logistic regression was performed to identify the possible factors related to an eGFR ≤30 ml/min per 1.73 m 2 at the last follow-up. Cox proportional hazards model was performed to assess the factors associated with the risk of relapse. RESULTS: We studied 101 adult patients with IgG4-related disease with a median follow-up of 24 (11-58) months. Of these, 87 (86%) patients were male, and the median age was 68 (57-76) years. Eighty-three (82%) patients had IgG4-related kidney disease confirmed by kidney biopsy, with all biopsies showing tubulointerstitial involvement and 16 showing glomerular lesions. Ninety (89%) patients were treated with corticosteroids, and 18 (18%) patients received rituximab as first-line therapy. At the last follow-up, the eGFR was below 30 ml/min per 1.73 m 2 in 32% of patients; 34 (34%) patients experienced a relapse, while 12 (13%) patients had died. By Cox survival analysis, the number of organs involved (hazard ratio [HR], 1.26; 95% confidence interval [CI], 1.01 to 1.55) and low C3 and C4 concentrations (HR, 2.31; 95% CI, 1.10 to 4.85) were independently associated with a higher risk of relapse, whereas first-line therapy with rituximab was protective (HR, 0.22; 95% CI, 0.06 to 0.78). At their last follow-up, 19 (19%) patients had an eGFR ≤30 ml/min per 1.73 m 2 . Age (odd ratio [OR], 1.11; 95% CI, 1.03 to 1.20), peak serum creatinine (OR, 2.74; 95% CI, 1.71 to 5.47), and serum IgG4 level ≥5 g/L (OR, 4.46; 95% CI, 1.23 to 19.40) were independently predictive for severe CKD. CONCLUSIONS: IgG4-related kidney disease predominantly affected middle-aged men and manifested as tubulointerstitial nephritis with potential glomerular involvement. Complement consumption and the number of organs involved were associated with a higher relapse rate, whereas first-line therapy with rituximab was associated with lower relapse rate. Patients with high serum IgG4 concentrations (≥5 g/L) had more severe kidney disease.

The mediating effect of fatigue in impaired quality of life in systemic lupus erythematosus: mediation analysis of the French EQUAL cohort.

OBJECTIVES: Mediation analyses were conducted to measure the extent to which musculoskeletal (MSK) flares and depression affected physical health through excessive fatigue. METHODS: Mediation analyses were performed in a large multicentre cohort of SLE patients. Domains of the LupusQoL and SLEQOL questionnaires were selected as outcomes, MSK flares according to the SELENA-SLEDAI flare index (SFI-R) score and depression defined by Center for Epidemiologic Studies-Depression scale (CES-D) scale as exposures and different fatigue domains from MFI-20 and LupusQoL questionnaires as mediators. For each model, total, direct, indirect effects and proportion of effect mediated by fatigue (i.e. proportion of change in health-related quality of life) were determined. RESULTS: Of the 336 patients, 94 (28%) had MSK flares at inclusion and 99 (29.5%) were considered with depression. The proportion of the total effect of MSK flares on physical health impairment explained by fatigue ranged from 59.6% to 78% using the LupusQOL 'Physical health' domain and from 51.1% to 73.7% using the SLEQOL 'Physical functioning' domain, depending on the fatigue domain selected. The proportion of the total effect of depression on physical health impairment explained by fatigue ranged from 68.8% to 87.6% using the LupusQOL 'Physical health' domain and from 79.3% to 103.2% using the SLEQOL 'Physical functioning' domain, depending on the fatigue domain selected. CONCLUSIONS: The effect of MSK flares and depression on physical health impairment is largely mediated by fatigue. Thus, the patient's perception of disease activity as measured by physical health is largely influenced by fatigue. In addition, fatigue has a significant negative impact on quality of lifeof SLE patients with depression. TRIAL REGISTRATION: ClinicalTrials.gov, http://clinicaltrials.gov, NCT01904812.

Severe Libman-Sacks endocarditis complicating antiphospholipid syndrome: a retrospective analysis of 23 operated cases.

OBJECTIVE: Data on severe heart valve disease (HVD), including Libman-Sacks endocarditis, associated with SLE and/or APS requiring valvular surgery are scarce. We thus conducted a retrospective study, aimed at describing and clarifying clinical, laboratory, echocardiographic, histopathological and evolutional features of SLE and/or APS patients with severe associated-HVD. METHODS: An observational retrospective multicentric analysis of 23 adults with SLE and/or APS and HVD between 1996 and 2019 and available histopathological report evaluating long-term follow-up. RESULTS: Twenty-three individuals (20 females, median age 37 [range 17-76] years) were included. All had APS (thrombotic in 22, with an arterial phenotype in 15 and with catastrophic APS [CAPS] in six), and 11 (47%) had SLE. Systemic underlying disease had been diagnosed prior to HVD in 12 (52%). In 10 patients (43%), HVD was complicated by cerebral stroke prior to surgery. Twenty patients (87%) had only one pathological valve, the mitral valve in 18 patients (78%). Valvular thickening (n = 19) and valvular regurgitation (n = 19) were the most frequently reported lesions. Fifteen (62%) patients underwent mechanical valve replacement, six (26%) conservative valve repair (five were later re-operated after a median time of 1 [0-4] year), and two (9%) underwent biological valve replacement. Nine patients (39%) presented early-onset post-operative complications, including three CAPS immediately after surgery and one death. After surgery, 18 patients (78%) had normal postoperative valvular function, but almost half of the patients (43%) had post-operative neurological sequelae (median follow-up of 6 [2-20] years). CONCLUSION: Severe HVD leading to surgery was strongly associated with thrombotic APS, especially arterial phenotypes. Half of the reported patients presented cerebral stroke complicating the HVD. Valvular surgery carried a significant risk of CAPS.

Giant cell arteritis in the elderly / Maladie de Horton du sujet âgé

Introduction: Giant cell arteritis (GCA) or Horton's disease is a segmental and focal inflammation of large and medium-sized arteries mostly seen in patients of 50 years and older. There is also a peak frequency in individuals between the ages of 70 and 80. However, clinical data is scarce in this age group and especially in patients over 80. Methods: A retrospective study comprised of patients diagnosed with Horton's arteritis between 2012 and 2017, according to the American Society of Rheumatology, was conducted at Reims University Hospital. Patients were assigned to two groups according to age (≤ 75 and < 75) in order to evaluate and compare the impact of age on diagnosis, treatment and prognosis. Results: A total of 67 patients were studied. The mean age upon diagnosis was 75,85 ±8.5 years; 36 patients (53.7%) 75 years or younger and 31 patients older than 75. There was a female predominance (43 patients), 22 patients aged 75 years or younger and 21 older than 75. The mean follow up duration was 43.02 months in patients aged 75 years or younger and 30.99 in patients older than 75. This represents a difference of more than one year in terms of follow up, but is not statistically significant (p = 0.620). Eleven patients (16.4%) died during follow up: 5 patients (13.9%) aged 75 years or younger and 6 patients (19.4%) older than 75 (p = 0.547). Aortitis was significantly less seen in patients older than 75 (p = 0.0410). Conclusion: Our study showed no significant difference in either age group. However, aortitis was less seen in patients older than 75 years. Patients aged 75 or younger seemed more prone to relapses, but their follow up periods were shorter.

Introduction: L'artérite à cellules géantes (ACG) ou maladie de Horton est une artérite inflammatoire segmentaire et focale des artères de gros et moyen calibre du sujet de plus de 50 ans, avec un pic de fréquence chez le sujet très âgé entre 70 et 80 ans. Dans cette classe d'âge et au-delà de 80 ans, les données cliniques concernant l'AGC sont peu nombreuses. Notre objectif est de documenter ces dernières à travers une étude monocentrique menée sur une population avec une AGC avérée. Patients et méthode: Nous avons mené une étude rétrospective, monocentrique sur les dossiers médicaux de patients diagnostiqués artérite de Horton selon les critères de l'ASR entre 2012 et 2017 au CHU de Reims. Pour évaluer l'influence de l'âge sur le plan diagnostic, thérapeutique, du suivi et du pronostic, nous avons comparé des patients de 75 ans et moins (≤ 75 ans) à ceux de plus de 75 ans (> 75 ans) sur ces différents points. Résultats: Soixante-sept patients ont été inclus. L'âge moyen au diagnostic de ces patients était de 75,85 ± 8,5 ans ; 36 patients (53,7 %) étaient âgés de 75 ans ou moins (dont 22 femmes) et 31 patients (46,3 %) étaient âgés de plus de 75 ans (dont 21 femmes). La médiane de suivi était de 43,02 mois chez les patients ≤ 75 ans et de 30,99 mois chez les > 75 ans, soit près d'un an de différence, mais non significative (p = 0,620). Onze patients (16,4 %) étaient décédés au cours du suivi, 5 (13,9 %) chez les patients ≤ 75 ans et 6 (19,4 %) chez les patients de > 75 ans (p = 0,547). Les patients > 75 ans avaient significativement moins d'aortite (p = 0,0410). Il y avait une tendance à moins de rechute chez les patients de > 75 ans (p = 0,067). Pour les autres symptômes ou anomalies biologiques, les résultats de la biopsie d'artère temporale, la prise en charge thérapeutique, les complications iatrogènes et les décès, aucune différence significative n'était mise en évidence entre les deux groupes (p = ns). Conclusion: Notre étude montre peu de différence en ce qui concerne l'AGC entre les patients > 75 ans et ceux ≤ 75 ans. Toutefois, les patients > 75 ans ont moins d'aortite que les sujets plus jeunes. Il semble également y avoir une tendance à davantage de rechute chez les sujets les plus jeunes, sous réserve d'une durée de suivi plus courte d'un an, cliniquement pertinente, chez les sujets les plus âgés.

Absence of Anti-Glomerular Basement Membrane Antibodies in 200 Patients With Systemic Lupus Erythematosus With or Without Lupus Nephritis: Results of the GOODLUPUS Study.

Introduction: Anti-glomerular basement membrane (GBM) antibodies are pathogenic antibodies first detected in renal-limited anti-GBM disease and in Goodpasture disease, the latter characterized by rapidly progressive crescentic glomerulonephritis combined with intra-alveolar hemorrhage. Studies have suggested that anti-GBM antibody positivity may be of interest in lupus nephritis (LN). Moreover, severe anti-GBM vasculitis cases in patients with systemic lupus erythematosus (SLE) have been described in the literature, but few studies have assessed the incidence of anti-GBM antibodies in SLE patients. Objective: The main study objective was to determine if positive anti-GBM antibodies were present in the serum of SLE patients with or without proliferative renal damage and compared to a healthy control group. Methodology: This retrospective study was performed on SLE patients' sera from a Franco-German European biobank, developed between 2011 and 2014, from 17 hospital centers in the Haut-Rhin region. Patients were selected according to their renal involvement, and matched by age and gender. The serum from healthy voluntary blood donors was also tested. Anti-GBM were screened by fluorescence enzyme immunoassay (FEIA), and then by indirect immunofluorescence (IIF) in case of low reactivity detection (titer >6 U/ml). Results: The cohort was composed of 100 SLE patients with proliferative LN (27% with class III, 67% with class IV, and 6% with class V), compared to 100 SLE patients without LN and 100 controls. Patients were mostly Caucasian and met the ACR 1997 criteria and/or the SLICC 2012 criteria. Among the 300 tested sera, no significant levels of anti-GBM antibodies were detected (>10 U/ml) by the automated technique, three sera were found "ambivalent" (>7 U/ml): one in the SLE with LN group and two in the SLE without LN group. Subsequent IIF assays did not detect anti-GBM antibodies. Conclusion: Anti-GBM antibodies were not detected in the serum of Caucasian patients with SLE, even in case of renal involvement, a situation favoring the antigenic exposure of glomerular basement membranes. Our results reaffirm the central role of anti-GBM antibodies as a specific diagnostic biomarker for Goodpasture vasculitis and therefore confirm that anti-GBM antibody must not be carried out in patients with SLE (with or without LN) in the absence of disease-suggestive symptoms.

Disease-specific quality of life following a flare in systemic lupus erythematosus: an item response theory analysis of the French EQUAL cohort.

OBJECTIVE: To explore, at an item-level, the effect of disease activity (DA) on specific health-related quality of life (HRQoL) in SLE patients using an item response theory longitudinal model. METHODS: This prospective longitudinal multicentre French cohort EQUAL followed SLE patients over 2 years. Specific HRQoL according to LupusQoL and SLEQOL was collected every 3 months. DA according to SELENA-SLEDAI flare index (SFI) and revised SELENA-SLEDAI flare index (SFI-R) was evaluated every 6 months. Regarding DA according to SFI and each SFI-R type of flare, specific HRQoL of remitting patients was compared with non-flaring patients fitting a linear logistic model with relaxed assumptions for each domain of the questionnaires. RESULTS: Between December 2011 and July 2015, 336 patients were included (89.9% female). LupusQoL and SLEQOL items related to physical HRQoL (physical health, physical functioning, pain) were most affected by musculoskeletal and cutaneous flares. Cutaneous flares had significant influence on self-image. Neurological or psychiatric flares had a more severe impact on specific HRQoL. Patient HRQoL was impacted up to 18 months after a flare. CONCLUSION: Item response theory analysis is able to pinpoint items that are influenced by a given patient group in terms of a latent trait change. Item-level analysis provides a new way of interpreting HRQoL variation in SLE patients, permitting a better understanding of DA impact on HRQoL. This kind of analysis could be easily implemented for the comparison of groups in a clinical trial. TRIAL REGISTRATION: ClinicalTrials.gov, http://clinicaltrials.gov, NCT01904812.

[Late-onset rheumatoid arthritis: clinical, biological, and therapeutic features About a retrospective study]. / Polyarthrite rhumatoïde à révélation tardive : caractéristiques cliniques, biologiques et thérapeutiques À propos d'une étude rétrospective.

Rheumatoid arthritis (RA) is the most common chronic inflammatory rheumatism in adults. The objective of our study was to analyze the clinical, biological and therapeutic characteristics in subjects over 60 years old. PATIENTS AND METHODS: We performed a retrospective, monocentric, descriptive study on medical records consultations. The data collection concerned subjects over 60 years of age who had been diagnosed with "rheumatoid arthritis" in the rheumatology and internal medicine departments of CHU Reims over a period stretching from 2010 to 2015. RESULTS: Thirty-two patients were included in our study for this period. The mean age of diagnosis was 66.6 years, for a median age of 67.5 years (min: 60 years, max: 88 years). There were 22 female (69%) and 10 male (31%) patients, with a sex ratio H/F of 2.2. The mean duration of symptom progression before diagnosis was 33.2 months. What dominates our series is the inaugural involvement of the interphalangeal proximal, wrists, shoulders and metacarpophalangeal for the vast majority of cases. Oral corticosteroids were used in 27 patients and were the only treatment in 3 patients. Methotrexate (MTX) was introduced in 27 patients. Nine patients received biotherapy: it was tocilizumab (Roactemra®) for 5 patients, adalimumab (Humira®) for 2 patients, abatacept (Orencia®) for 2 patients, etanercept (Enbrel®) for 2 patients, golimumab (Simponi®) for 1 patient and infliximab (Remicade®) for one patient. In our series, 7 patients are over 75 years old at the time of diagnosis of RA. CONCLUSION: The rheumatoid arthritis of the elderly remains a common condition and constitutes a diagnostic and therapeutic challenge. Because of the co-morbidities, the clinician's perception of the patient's overall condition and the inaccuracies in the use of certain molecules in these patients, under-treatment may, on the contrary, weaken a patient whose remission will be postponed. This was not the case in our series, with a methodical use of methotrexate as well as effective dose biotherapies.

Predictors of fatigue and severe fatigue in a large international cohort of patients with systemic lupus erythematosus and a systematic review of the literature.

OBJECTIVE: Fatigue is reported in up to 90% of patients with SLE. This study was conducted to identify the determinants associated with fatigue in a large cohort of patients with SLE, as well as to provide a systematic review of the literature. METHODS: Patients from the Lupus BioBank of the upper Rhein, a large German-French cohort of SLE patients, were included in the FATILUP study if they fulfilled the 1997 ACR criteria for SLE and had Fatigue Scale for Motor and Cognitive Functions scores collected. Multivariate logistic regression analyses were performed to assess the determinants of fatigue and severe fatigue. RESULTS: A total of 570 patients were included (89.1% female). The median age was 42 years (interquartile range 25-75: 34-52). The median value of the SAfety of Estrogens in Lupus Erythematosus National Assessment (SELENA)-SLEDAI was 2 (0-4). Fatigue was reported by 386 patients (67.7%) and severe fatigue by 209 (36.7%). In multivariate analyses, fatigue was associated with depression [odds ratio (OR): 4.72 (95% CI: 1.39-16.05), P = 0.01], anxiety [OR: 4.49 (95% CI: 2.60-7.77), P < 0.0001], glucocorticoid treatment [OR: 1.59 (95% CI 1.05-2.41), P = 0.04], SELENA-SLEDAI scores [OR: 1.05 (95% CI: 1.00-1.12) per 1 point increase, P = 0.043] and age at sampling [OR: 1.01 (95% CI: 1.00-1.03) per 1 year increase, P = 0.03]. Severe fatigue was independently associated with anxiety (P < 0.0001), depression (P < 0.0001), glucocorticoid treatment (P = 0.047) and age at sampling (P = 0.03). CONCLUSION: Both fatigue and severe fatigue are common symptoms in SLE, and are strongly associated with depression and anxiety. Disease activity and the use of glucocorticoids were also independently associated with fatigue, although more weakly.

Characteristics and clinical outcomes after treatment of a national cohort of PCR-positive Lyme arthritis.

OBJECTIVES: To describe the clinical and microbiological characteristics and outcomes after antibiotic treatment of a national cohort of patients with Lyme arthritis confirmed by PCR testing on synovial fluid and by serology, when available. METHODS: Using the French National Reference Center for Borrelia database, patients with a positive PCR on synovial fluid for Borrelia were identified. Patient clinical and biological characteristics were reviewed from patient records. Long-term outcomes after treatment were studied through a questionnaire and with follow-up data. RESULTS: Among 357 synovial fluid testing by PCR between 2010 and 2016, 37 (10.4%) were positive for Borrelia. Patients' median age was 36 years (range 6-78) with 61% of men and 28% patients under 18. The presentation was monoarticular in 92% and the knee was involved in 97%. Contrary to the Borrelia species repartition in European ticks, B. burgdorferi sensu stricto was the most prevalent species found in synovial fluid (54%) followed by B. azfelii (29%) and B. garinii (17%). Antibiotic treatments were mainly composed of doxycycline (n = 24), ceftriaxone (n = 10) and amoxicillin (n = 6), for a median duration of 4 weeks (range 3-12). Despite a properly conducted treatment, 34% of patients (n = 12) developed persistent synovitis for at least 2 months (median duration 3 months, range 2-16). Among those, 3 developed systemic inflammatory oligo- or polyarthritis in previously unaffected joints with no signs of persistent infection (repeated PCR testing negative), which mandated Disease-Modifying Antirheumatic Drugs (DMARD) introduction, leading to remission. CONCLUSION: In France and contrary to ticks ecology, Lyme arthritis is mainly caused by B. burgdorferi sensu stricto. Despite proper antibiotic therapy, roughly one third of patients may present persistent inflammatory synovitis and a small proportion may develop systemic arthritis. In such cases, complete remission can be reached using DMARD.

Long-term efficacy and safety of rituximab in IgG4-related disease: Data from a French nationwide study of thirty-three patients.

OBJECTIVES: To assess efficacy and safety of rituximab (RTX) as induction therapy, maintenance of remission and treatment of relapses in a cohort of IgG4-related disease (IgG4-RD) patients. METHODS: Nationwide retrospective multicenter study of IgG4-RD patients treated with at least one course of RTX. Clinical, biological and radiological response, relapse rate and drug tolerance were analyzed. Kaplan-Meier curves were plotted and risk factors for relapse studied with a Cox regression model. RESULTS: Among 156 IgG4-RD patients included in the French database, 33 received rituximab. Clinical response was noted in 29/31 (93.5%) symptomatic patients. Glucocorticoids withdrawal was achieved in 17 (51.5%) patients. During a mean follow-up of 24.8 ±21 months, 13/31 (41.9%) responder patients relapsed after a mean delay of 19 ±11 months after RTX. Active disease, as defined by an IgG4-RD Responder Index >9 before RTX, was significantly associated with relapse (HR = 3.68, 95% CI: 1.1, 12.6) (P = 0.04), whereas maintenance therapy with systematic (i.e. before occurrence of a relapse) RTX retreatment was associated with longer relapse-free survival (41 versus 21 months; P = 0.02). Eight severe infections occurred in 4 patients during follow-up (severe infections rate of 12.1/100 patient-years) and hypogammaglobulinemia ≤5 g/l in 3 patients. CONCLUSION: RTX is effective for both induction therapy and treatment of relapses in IgG4-RD, but relapses are frequent after B-cell reconstitution. Maintenance therapy with systematic RTX infusions is associated with longer relapse-free survival and might represent a novel treatment strategy. Yet, the high rate of infections and the temporary effect of RTX might be hindrances to such strategy.

In Vitro Fertilization in 37 Women with Systemic Lupus Erythematosus or Antiphospholipid Syndrome: A Series of 97 Procedures.

OBJECTIVE: To compile and assess data about complication and success rates for in vitro fertilization (IVF) of women with systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS). To date, such data are sparse. METHODS: This retrospective study described women with SLE and/or APS who have had at least 1 IVF cycle. RESULTS: Thirty-seven women with SLE (n = 23, including 8 with antiphospholipid antibodies), SLE with APS (n = 4), or primary APS (n = 10) underwent 97 IVF procedures. For 43% of cases, the infertility was female in origin, for 19% male, 14% mixed, and 24% unexplained. No women had premature ovarian insufficiency because of cyclophosphamide. Median age at IVF was 34 years (range 26-46). The median number of IVF cycles was 2.6 (1-8). Patients were treated with hydroxychloroquine (72%), steroids (70%), azathioprine (3%), aspirin (92%), and/or low molecular weight heparin (62%). There were 27 (28%) pregnancies, 23 live births among 26 neonates (3 twin pregnancies), 2 miscarriages, and 2 terminations for trisomy 13 and 21. Six spontaneous pregnancies occurred during the followup. Finally, 26 women (70%) delivered at least 1 healthy child. Complications occurred in or after 8 IVF cycles (8%): SLE flares in 4 (polyarthritis in 3 and lupus enteritis in 1) and thromboembolic events in 4 others. One SLE flare was the first sign of previously undiagnosed SLE. Poor treatment adherence was obvious in 2 other flares and 2 thromboses. No ovarian hyperstimulation syndrome was reported. CONCLUSION: These preliminary results confirm that IVF can be safely and successfully performed in women with SLE and/or APS.

Treatment in idiopathic thrombocytopenic purpura in the elderly: about a retrospective study.

There are no specific recommendations on the care of elderly patients with ITP. A retrospective study over two academic centers (Reims and Strasbourg), focused on patients over 65 who have been diagnosed idiopathic thrombocytopenic purpura in two unit of internal medicine. 41 patients were enrolled, including 27 women (66%). The median age is 76.75 years. On admission, the average thrombocytopenia is 34.45 G/L; 24 patients (58.5%) showed severe bleeding mucosal and/or visceral signs; 37 patients (90%) had a first-line treatment. Corticosteroids established for 23 patients (56%). At 1 and 6 months, complete response was 9 patients (39%) and 2 patients (9%) respectively. Adverse events reported for 20 patients (87%). Polyvalent immunoglobulins were used for 6 (16%) with no response at 6 months. 5 patients were treated with danazol. At 6 months, partial response in 3 patients (60%) and failure in 2 patients (40%). Splenectomy was performed for 8 patients (21%). At 1 month, a complete response observed for 7 patients. At 6 months, a failure observed in 4 patients. After failure of first-line treatments, we noted the use of rituximab for 4 patients (9.7%) with a complete response for 1 patient, partial response in 2 patients and a failure for a patient for whom the "eltrombopag" was set up with a partially response. Monitoring of 41 patients, during 7 years, objectified 3 deaths. The clinical presentation of idiopathic thrombocytopenic purpura in the elderly seems more severe. Therapeutic responses are essentially identical to those observed in younger patients, but greater toxicity. Data on biologics is nonexistent in elderly outside small retrospective series. Studies are underway to better assess their effectiveness, long-term safety as well as their mechanism of action.

Systemic Lupus Erythematosus and Antineutrophil Cytoplasmic Antibody-Associated Vasculitis Overlap Syndrome in Patients With Biopsy-Proven Glomerulonephritis.

The aim of the study was to report the clinical, biological, and pathological characteristics of patients with glomerulonephritis (GN) secondary to systemic lupus erythematosus (SLE)/antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) overlap syndrome.A nationwide survey was conducted to identify cases of SLE/AAV overlap syndrome. Data were collected from SLE and AAV French research groups. Inclusion criteria were diagnosis of both SLE and AAV according to international classification criteria and biopsy-proven GN between 1995 and 2014. Additional cases were identified through a systematic literature review. A cohort of consecutive biopsy-proven GN was used to study the prevalence of overlapping antibodies and/or overlap syndrome.The national survey identified 8 cases of SLE/AAV overlap syndrome. All patients were female; median age was 40 years. AAV occurred before SLE (n = 3), after (n = 3), or concomitantly (n = 2). Six patients had rapidly progressive GN and 3/8 had alveolar hemorrhage. All patients had antinuclear antibodies (ANA); 7/8 had p-ANCA antimyeloperoxidase (MPO) antibodies. Renal biopsies showed lupus nephritis (LN) or pauci-immune GN. Remission was obtained in 4/8 patients. A literature review identified 31 additional cases with a similarly severe presentation. In the GN cohort, ANCA positivity was found in 30% of LN, ANA positivity in 52% of pauci-immune GN, with no correlation with pathological findings. The estimated prevalence for SLE/AAV overlap syndrome was 2/101 (2%).In patients with GN, SLE/AAV overlap syndrome may occur but with a low prevalence. Most patients have an aggressive renal presentation, with usually both ANA and anti-MPO antibodies. Further studies are needed to assess shared pathogenesis and therapeutic options.

[Iron deficiency and pernicious anemia: a rare association?]. / Carence martiale et maladie de Biermer : une association rare ?

The aim of this study was to determine the prevalence of iron deficiency among patients with pernicious anemia. We realized a retrospective study from 2000 to 2010 including 55 patients suffering from pernicious anemia who were followed in Reims and Strasbourg university hospitals. Inclusion criteria were histological diagnosis of immune atrophic fundic gastritis and criteria of gastric autoimmuninty, and for which ferritin was measured. Iron deficiency is defined as serum ferritin level <20 µg/L in women and <30 µg/L in men. 45 (81.8%) patients were female. The mean age was 61 ± 17 years (range: 25/98).There was anemia in 32 patients (58.2%). Macrocytosis was noted, with or without anemia, in 30 patients (54.5%); microcytosis, with or without anemia, was noted in 8 (14.5%) patients. 17 patients (30.9%) had normal mean corpuscular volume. Vitamin B12 deficiency was objectived in 42 patients (76.4%) in our series. 16 patients (29%) had iron deficiency. 14 patients were female. They were significantly younger than female subjects without iron deficiency (p =0.004). In conclusion, iron deficiency is not rare in patients with pernicious anemia. It could be a complication of achlorhydria. We suggest a dosage of serum ferritin for all patients with pernicious anemia.

[Late-onset lupus in the elderly after 65 years: retrospective study of 18 cases]. / Le lupus érythémateux systémique survenant après 65 ans : étude rétrospective de 18 cas.

OBJECTIVE: The aim of our study was to investigate characteristics of late-onset lupus after 65 years compared to younger ones. METHOD: Patients with lupus revealed after 65 years were investigated in four French hospitals between 1985 and 2013. Patients with 4 ACR criteria or more were included. Clinical and biological characteristics, prognosis, treatment, comorbidities were described retrospectively and compared to the cohort of 1000 lupus patients of Cervera et al. RESULTS: Eighteen patients were included (14 women and 4 men). The most frequent features were arthritis (13/18), skin involvement (9/18). Hemolytic anemia and thrombosis were more frequently found in elderly lupus (p<0.05). During evolution, only cutaneous involvement were less frequent than in young subjects (p <0.05). Corticosteroids were often used (16/18), but iatrogenic complications were frequent (10/16). CONCLUSION: Diagnosis is difficult because of non-specific clinical features. Treatment needed a rigourous follow-up because of iatrogenic complications.
