Determination of four homogeneous subgroups of patients with antiphospholipid syndrome: a cluster analysis based on 509 cases.

OBJECTIVE: APS is a heterogeneous disease with different phenotypes. Using an unsupervised hierarchical cluster analysis, we aimed to determine distinct homogeneous phenotypes among APS patients. METHODS: We performed an observational, retrospective study of APS patients enrolled in the French multicentre 'APS and SLE' registry who met the Sydney classification criteria. The clustering process involved an unsupervised multiple correspondence analysis followed by a hierarchical ascendant clustering analysis; it used 27 variables selected to cover a broad range of APS clinical and laboratory manifestations. RESULTS: These analyses included 509 patients, mainly women (77.8%). Mean (s.d.) age at APS diagnosis was 36.2 (14.6) years, and mean follow-up since diagnosis 10.3 (8.5) years. This hierarchical classification cluster analysis yielded four homogeneous groups of patients: cluster 1, mostly with venous thromboembolism without any associated autoimmune disease; cluster 2, older, lowest proportion of women, history of arterial events, and/or with migraines, arterial hypertension, diabetes mellitus, or dyslipidaemia; cluster 3, younger, highest proportion of women, associated SLE or other autoimmune diseases, and a history of venous thromboembolism or pregnancy morbidity; and cluster 4, mainly with a history of catastrophic antiphospholipid syndrome, aPL-associated nephropathy, and pregnancy morbidity, with frequent triple positivity and more deaths (16.7%). CONCLUSIONS: Our study applied an unsupervised clustering method to distinguish four homogeneous APS patient subgroups that were predominantly venous; arterial; associated with SLE or another autoimmune disease; and arterial microthrombotic. Heterogeneous pathophysiological mechanisms may explain these findings.

Relevance of inflammatory and complement activation biomarkers profiling in antiphospholipid syndrome patients outside acute thrombosis.

OBJECTIVES: To evaluate whether inflammatory and complement biomarkers are associated with specific characteristics of antiphospholipid syndrome (APS). METHODS: Serum levels of interleukin (IL)-1ß (IL-1ß), IL-6, IL-8, IL-10, tumour necrosis factor (TNF)-α, interferon-α (IFN)-α, IFN-γ, vascular endothelial growth factor (VEGF), intercellular adhesion molecule 1 (ICAM-1), E-selectin, and vascular cell adhesion molecule (VCAM)-1, and plasma levels of soluble C5b-9 (sC5b-9), C3a, C4a, Bb fragment were measured in unselected APS patients. Twenty-five healthy blood donors were included as controls. RESULTS: Between January 2020 and April 2021, 98 APS patients were included outside acute thrombosis (median time from the last APS manifestation: 60 (23;132) months). Levels of IL6, VCAM-1, sC5b-9, C3a, C4a, and Bb were significantly increased in APS patients compared to controls. A cluster analysis allowed to divide patients into two clusters: "inflammatory" (higher levels of IL-6 and VCAM-1) and "complement". In APS, elevated IL-6 was associated with hypertension, diabetes, BMI, and hypertriglyceridaemia. 85% of our APS patients had elevated levels of at least one complement biomarker. Elevated Bb (34%) was associated with aPL positivities, especially with triple aPL positivity (50% vs. 18%, p<0.001). 7/8 patients with history of catastrophic APS had elevated levels of complement biomarkers. CONCLUSIONS: Our findings suggested that APS patients outside acute thrombosis might be divided into two clusters: "inflammatory" and "complement". Elevated IL-6 was associated with cardiovascular risk factors and metabolic parameters, whereas Bb fragments, a marker of alternative pathway complement activation, was strongly associated with aPL profile at highest risk of severe disease.

Cerebrovascular Ischemic Events in Patients With Takayasu Arteritis.

BACKGROUND: Takayasu arteritis (TA) is a large vessel vasculitis that may complicate with cerebrovascular ischemic events. The objective was to describe clinical and vascular features of TA patients with cerebrovascular ischemic events and to identify risk factors for these events. METHODS: We analyzed the prevalence and type of stroke/transient ischemic attack (TIA), factors associated with cerebrovascular ischemic events, and stroke-free survival in a large cohort fulfilling the American College of Rheumatology or Ishikawa criteria of TA. RESULTS: Among 320 patients with TA (median age at diagnosis, 36 [25-47] years; 261 [86%] women), 63 (20%) had a stroke (n=41; 65%) or TIA (n=22; 35%). Ischemic event localized in the carotid territory for 55 (87%) patients and the vertebral artery territory in 8 (13%) patients. Multiple stenosis were observed in 33 (52%) patients with a median number of stenosis of 2 (minimum, 0 to maximum, 11), and aneurysms were observed in 10 (16%) patients. A history of stroke or TIA before TA diagnosis (hazard ratio [HR], 4.50 [2.45-8.17]; P<0.0001), smoking (HR, 1.75 [1.01-3.02]; P=0.05), myocardial infarction history (HR, 0.21 [0.05-0.89]; P=0.039), thoracic aorta involvement (HR, 2.05 [1.30-3.75]; P=0.023), time from first symptoms to diagnosis >1 year (HR, 2.22 [1.30-3.80]; P=0.005), and aspirin treatment (HR, 1.82 [1.04-3.19]; P=0.035) were associated with cerebrovascular ischemic event. In multivariate analysis, time from first symptoms to TA diagnosis >1 year (HR, 2.16 [1.27-3.70]; P=0.007) was independently associated with cerebrovascular ischemic events in patients with TA. The HR for cerebrovascular ischemic event in patients who already experienced a stroke/TIA was 5.11 (2.91-8.99; P<0.0001), compared with those who had not. CONCLUSIONS: Carotid stroke/TIA is frequent in TA. We identified factors associated with cerebrovascular ischemic events.

Weaning of maintenance immunosuppressive therapy in lupus nephritis (WIN-Lupus): results of a multicentre randomised controlled trial.

OBJECTIVES: Lupus nephritis (LN) is a frequent complication of systemic lupus erythematosus (SLE). Severe (proliferative) forms of LN are treated with induction immunosuppressive therapy (IST), followed by maintenance IST, to target remission and avoid relapses. The optimal duration of maintenance IST is unknown. The WIN-Lupus trial tested whether IST discontinuation after 2‒3 years was non-inferior to IST continuation for two more years in proliferative LN. METHODS: WIN-Lupus was an investigator-initiated multicentre randomised controlled trial. Patients receiving maintenance IST with azathioprine or mycophenolate mofetil for 2-3 years, and hydroxychloroquine, were randomised (1:1) into two groups: (1) IST continuation and (2) IST discontinuation. The primary endpoint was the relapse rate of proliferative LN at 24 months. Main secondary endpoints were the rate of severe SLE flares, survival without renal relapse or severe flare, adverse events. RESULTS: Between 2011 and 2016, 96 patients (out of 200 planned) were randomised in WIN-Lupus: IST continuation group (n=48), IST discontinuation group (n=48). Relapse of proliferative LN occurred in 5/40 (12.5%) patients with IST continuation and in 12/44 (27.3%) patients with IST discontinuation (difference 14.8% (95% CI -1.9 to 31.5)). Non-inferiority was not demonstrated for relapse rate; time to relapse did not differ between the groups. Severe SLE flares (renal or extrarenal) were less frequent in patients with IST continuation (5/40 vs 14/44 patients; p=0.035). Adverse events did not differ between the groups. CONCLUSIONS: Non-inferiority of maintenance IST discontinuation after 2‒3 years was not demonstrated for renal relapse. IST discontinuation was associated with a higher risk of severe SLE flares. TRIAL REGISTRATION NUMBER: NCT01284725.

Renal and vascular outcomes in patients with isolated antiphospholipid syndrome nephropathy.

BACKGROUND: Antiphospholipid syndrome (APS) nephropathy (APSN) is a rare pattern with specific features resulting from microvascular lesions. The prognosis of APSN, outside of lupus nephritis, is unknown. The aim of this study was to describe the renal, vascular and overall outcomes of patients with APSN. METHODS: Retrospective multicenter study of patients with antiphospholipid antibodies (aPL) associated with histological APSN lesions and no other nephropathy, identified through a national call for medical records. End-stage renal disease (ESRD)-free survival, thrombosis recurrence-free survival and overall survival were assessed. RESULTS: Thirty patients were included (19 women) with a median age of 40 years (34-52 years). Fifteen patients had APS, 26/28 had lupus anticoagulant, and 15/26 had triple positivity for aPL. Median eGFR was 50 (31-60) mL/min/1.73 m2. Glomerular thrombotic microangiopathy was found in 12/24 cases, fibrous intimal hyperplasia in 12/22 cases and focal cortical atrophy in 17/29 cases. Nineteen patients had moderate to severe interstitial fibrosis (>25%). Six patients developed ESRD at a median follow-up of 6.2 (1.8-9.1) years. The ESRD-free survival rates at 5 and 10 years were 80.0% (95% CI 57.6%-91.4%) and 72.7% (95% CI, 46.9%-87.4%) respectively. None of the histological factors considered was significantly associated with a decrease in eGFR at 12 months. Thrombosis recurrence-free survival was 77.8% (95% CI 48.2%-91.6%) at 10 years. Overall survival was 94% at 10 years (95% CI 65.0%-99.2%). CONCLUSIONS: The renal prognosis of isolated APSN is poor. The severe fibrotic lesions observed are suggestive of late diagnosis.

Efficacy and safety of TNF-α antagonists and tocilizumab in Takayasu arteritis: multicentre retrospective study of 209 patients.

OBJECTIVE: To assess the safety and the efficacy of TNF-α antagonists and tocilizumab in patients with Takayasu arteritis (TAK). METHODS: A total of 209 patients with TAK [median age 29 years (interquartile range 7-62)], 186 (89%) females] were included. They received either TNF-α antagonists [n = 132 (63%) with 172 lines; infliximab (n = 109), adalimumab (n = 45), golimumab (n = 8), certolizumab (n = 6) and etanercept (n = 5)] or tocilizumab [n = 77 (37%) with 121 lines; i.v. and s.c. in 95 and 26 cases, respectively]. RESULTS: A complete response at 6 months was evidenced in 101/152 (66%) patients on TNF-α antagonists and 75/107 (70%) patients on tocilizumab. Age ≥30 years [odds ratio 2.09 (95% CI 1.09, 3.99)] was associated with complete response, whereas vascular signs [OR 0.26 (95% CI 0.1, 0.65)], baseline prednisone ≥20 mg/day [OR 0.51 (95% CI 0.28, 0.93)] were negatively associated with the complete response to TNF-α antagonists or tocilizumab. During a median follow-up of 36 months, 103 relapses were noted. Supra-aortic branches and thoracic aorta involvement [HR 2.44 (95% CI 1.06, 5.65) and 3.66 (1.18, 11.4), respectively] and systemic signs at baseline [HR 2.01 (95% CI 1.30, 3.11)] were significantly associated with relapse. The cumulative incidence of treatment discontinuation and relapse were similar in TNF-α antagonists and tocilizumab. Fifty-eight (20%) adverse effects occurred on biologic targeted therapies [37 (21%) on TNF-α antagonists and 21 (17%) on tocilizumab (P = 0.4), respectively]. CONCLUSION: This large multicentre study shows high efficacy of biologic targeted treatments in refractory TAK. Efficacy, relapse and drug retention rate were equivalent with TNF-α antagonists and tocilizumab.

Dyslipidemia is insufficiently treated in antiphospholipid syndrome patients.

OBJECTIVES: Although dyslipidemia is a strong risk factor for thrombosis in antiphospholipid syndrome (APS), it has been poorly studied. This study aimed to assess lipids profile and risk factors for unachieved cholesterol levels in a real-life APS population. METHODS: Inclusion criteria were: APS diagnosis according to international classification criteria, referring to the out-patients clinic of our tertiary care center for their follow-up, and having a blood sample collection for lipids levels determination. Cholesterol level targets for each patient were defined according to 2019 ESC/EAS guidelines for the management of dyslipidemia. RESULTS: Between January 2020 and April 2021, 114 APS patients were included (male 37 (32.5%); mean age 49 ± 14 years). Among them, 40 (35.1%) had a history of dyslipidemia, 48 (42.1%) were under lipid-lowering therapies, and 59 (51.8%) had a history of cardiovascular disease (CVD). Mean levels of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride were, respectively, 110 ± 40 mg/dL, 60±20 mg/dL, and 120 (80-190) mg/dL. Unachieved LDL-C levels were found in 77 (67.5%) patients of whom 53 had history of CVD. Overall, 90 (78.9%) had protective HDL-C and 31 (27.2%) had hypertriglyceridemia. In the multivariate analysis, independent risk factors for unachieved LDL-C levels were older age and history of CVD; triple aPL negativity, defined as complete disappearance of aPL over time in APS patients who were previously positive in accordance to international criteria, was an independent protective factor for unachieved LDL-C. CONCLUSION: Our finding suggested that dyslipidemia is frequent in APS patients and mainly insufficiently treated, especially in patients with history of CVD, who are at highest risk of future CV events.

Gender differences in primary antiphospholipid syndrome with vascular manifestations in 433 patients from four European centres.

OBJECTIVES: Gender can influence incidence and clinical course of autoimmune diseases (ADs). Antiphospholipid syndrome (APS) is a rare AD characterised by thromboses and/or pregnancy morbidities and antiphospholipid antibodies (aPL) positivity. Our aim is to conduct a gender-oriented analysis of primary thrombotic APS (t-APS). METHODS: Consecutive patients diagnosed with primary t-APS, followed from 1967 to 2019 in four European Centres, were enrolled. RESULTS: The cohort included 296 women and 137 men. Median age at onset [31 (24-46) vs. 41 (29-53) years, p<0.001] was lower in females. In women, venous thromboses were more frequent while, among males, arterial events prevailed. During follow-up, 14% of patients suffered at least two relapses and this occurred especially among males (22% vs. 10%, p=0.001). No gender differences were found in the aPL profile (33% single, 24% double and 43% triple aPL positivity). Most patients had concomitant risk factors (RFs) for thrombosis: established cardiovascular RFs were represented especially among men while estrogenic exposure was the main RF in women. CONCLUSIONS: Women presented mostly with venous thromboses at a younger age, while men with arterial events, later in life and suffered more recurrent events. This different frequency of arterial and venous thromboses could be attributed mainly to the presence of additional RFs rather than to biological gender-specific issues. However, some RFs are exclusive or more represented in one gender rather than the other, so assessing the link of causality between gender and manifestations of t-APS remains difficult.

Serious Infectious Events and Immunoglobulin Replacement Therapy in Patients With Autoimmune Disease Receiving Rituximab: A Retrospective Cohort Study.

BACKGROUND: Rituximab (RTX) is widely administered to patients with autoimmune disease (AID). This study aimed to estimate the incidence of serious infectious events (SIEs) after RTX initiation in patients with AID. We also described the characteristics and risk factors of SIEs, and immunoglobulin replacement therapy (IgRT) strategies. METHODS: Patients treated between 2005 and 2016 were included in this retrospective monocentric cohort study. An RTX course was defined as the complete RTX treatment regimen received by a given patient for AID. SIEs and IgRT were right-censored at 24 months after RTX initiation. RESULTS: Two hundred twenty-one patients were included (corresponding to 276 RTX courses). Reasons for RTX initiation included connective tissue disease (38%), systemic vasculitis (36%), and autoimmune cytopenia (22%). The 1- and 2-year incidences of SIEs were 17.3 (95% confidence interval [CI], 12.0-22.5) and 11.3 (95% CI, 8.1-14.5) per 100 person-years, respectively. Forty-seven SIEs were observed, mostly comprising pneumonias (45%) and bacteremias (21%). When documented, the microorganisms were bacterial (55%) and fungal (12%). Identified risk factors of SIEs were age, history of diabetes, history of cancer, concomitant steroid treatment, and low CD4 lymphocyte count at RTX initiation. IgRT was started in 22 RTX courses (8%). CONCLUSIONS: In patients with AID treated with RTX, the 1- and 2-year incidence of SIE was 17.3 and 11.3 per 100 person-years, respectively. Reports of SIE characteristics, risk factors, and IgRT strategies highlight the need for an appropriate and individualized assessment prior to and following RTX to prevent SIEs, particularly in patients with comorbidities.

Women and Pregnancy in Thromboangiitis Obliterans.

Data regarding women and thromboangiitis obliterans (TAO) are conflicted, and a few cases of pregnancy have been described. We aimed to describe the interplay between TAO and pregnancies. Among 224 TAO patients, 22.8% were women. Demographic data, clinical manifestations, and outcomes were similar between men and women. Twenty-one (41.2%) women had 48 pregnancies. Thirty-six (75%) pregnancies with on term and complication free delivery occurred. None of the patients experienced a disease flare of TAO during pregnancy. TAO does not seem to affect pregnancy complications, and pregnancy does not seem to interfere with the course of TAO.

Is the presence of antiphospholipid antibodies a poor prognostic factor for patients with hemolysis, elevated liver enzymes, and low platelet count syndrome?

BACKGROUND: The characteristics of antiphospholipid syndrome-associated hemolysis, elevated liver enzymes, and low platelet count syndrome are poorly described, likely because of the low frequency of this combination of syndromes. OBJECTIVE: This study aimed to compare the characteristics and prognosis of hemolysis, elevated liver enzymes, and low platelet count syndrome in patients with and without antiphospholipid syndrome. STUDY DESIGN: In this multicenter, case-control study, adult women diagnosed with hemolysis, elevated liver enzymes, and low platelet count syndrome before 34 weeks' gestation and who were also tested for antiphospholipid antibodies according to international diagnostic recommendations were included. Cases labeled "HELLP-APS+" were defined as patients who fulfilled the international classification criteria for antiphospholipid syndrome; they were retrospectively recruited by screening the 672 patients with antiphospholipid syndrome in our antiphospholipid syndrome database. Control cases labeled "HELLP-APS-" were defined as patients who did not fulfill the criteria for antiphospholipid syndrome; they were retrospectively recruited from our hospital admission database. RESULTS: Overall, 71 patients were included (mean age, 30±5 years), with 23 patients in the hemolysis, elevated liver enzymes, and low platelet count syndrome with antiphospholipid syndrome group and 48 patients in the hemolysis, elevated liver enzymes, and low platelet count syndrome without antiphospholipid syndrome group. The live birth rate was significantly lower for patients with hemolysis, elevated liver enzymes, and low platelet count with antiphospholipid syndrome than for those with hemolysis, elevated liver enzymes, and low platelet count syndrome without antiphospholipid syndrome (43.5% vs 89.4%; P<.001). The patients with hemolysis, elevated liver enzymes, and low platelet count syndrome with antiphospholipid syndrome gave birth prematurely more often than the patients without antiphospholipid syndrome (24 weeks' gestation; 22.0-28.0 weeks vs 30 weeks' gestation; 27.0-33.0 weeks; P<.001). Among the patients with hemolysis, elevated liver enzymes, and low platelet count syndrome with antiphospholipid syndrome, 39% required an induced abortion owing to hemolysis, elevated liver enzymes, and low platelet count syndrome severity vs 8.5% of the patients with hemolysis, elevated liver enzymes, and low platelet count syndrome without antiphospholipid syndrome (P=.006). The intensive care unit admission rate was 61.9% in patients with hemolysis, elevated liver enzymes, and low platelet count syndrome with antiphospholipid syndrome, which was significantly higher than the rate of 27.7% in patients with hemolysis, elevated liver enzymes, and low platelet count syndrome without antiphospholipid syndrome (P=.007). None of the mothers died. CONCLUSION: Our results suggest that the presence of antiphospholipid syndrome is a poor prognostic factor for both the mother and fetus in patients with hemolysis, elevated liver enzymes, and low platelet count syndrome.

CATASTROPHIC ANTIPHOSPHOLIPID SYNDROME AND POSTERIOR OCULAR INVOLVEMENT: Case Series of 11 Patients and Literature Review.

PURPOSE: To describe the posterior ophthalmic manifestations of catastrophic antiphospholipid syndrome. METHODS: Retrospective case series of patients presenting with catastrophic antiphospholipid syndrome and posterior segment ocular manifestations. The main outcomes were the type of posterior segment manifestations at catastrophic antiphospholipid syndrome diagnosis, specifically retinal vascular occlusion, vasculitis, or choroidopathy, and the final best-corrected visual acuity. RESULTS: This study included 23 patients (11 cases treated by the authors and 12 published case reports); 21 (91%) of them female. Their median age at diagnosis was 28 years (range, 16-79 years). Ophthalmologic manifestations were usually bilateral (n = 19, 83%) and involved vascular occlusive retinopathy (n = 17, 74%), choroidopathy (n = 11, 48%), or retinal vasculitis (n = 1, 4%). Final best-corrected visual acuity was not significantly worse than the best-corrected visual acuity at diagnosis (P = 0.16). Retinal vascular occlusions were associated with poorer final visual acuity than choroidopathy (P = 0.002). After a median follow-up of 14 months (range, 2-132 months), nearly half the patients (n = 11, 48%) had permanent vision loss including best-corrected visual acuity of <20/400 for 4 patients. CONCLUSION: Posterior ophthalmic manifestations of catastrophic antiphospholipid syndrome were mainly bilateral retinal vascular occlusion, which had the worst visual prognosis, followed by choroidopathy and retinal vasculitis. Permanent visual loss was common.

National early warning score to predict intensive care unit transfer and mortality in COVID-19 in a French cohort.

BACKGROUND: No risk stratification tool has been validated in hospitalised patients with coronavirus disease 2019 (COVID-19), despite a high rate of intensive care requirement and in-hospital mortality. We aimed to determine whether the National Early Warning Score (NEWS) at admission can accurately predict in-hospital mortality and ICU transfer. METHODS: This was a retrospective cohort study from January 24 to April 16, 2020, at Lille University Hospital. All consecutive adult patients with laboratory-confirmed COVID-19 who were initially admitted to non-ICU wards were included. The primary outcome was a composite criterion consisting of ICU transfer or in-hospital mortality. We evaluated the prognostic performance of NEWS by calculating the area under (AUC) the receiver operating characteristic curve, the optimal threshold value of NEWS, and its association with the primary outcome. RESULTS: Of the 202 COVID-19 patients, the median age was 65 (interquartile range 52-78), 38.6% were women and 136 had at least one comorbidity. The median NEWS was 4 (2-6). A total of 65 patients were transferred to the ICU or died in the hospital. Compared with patients with favourable outcome, these patients were significantly older, had more comorbidities and higher NEWS. The AUC for NEWS was 0.68 (0.60-0.77) and the best cutoff value was 6. Adjusted odds ratio for NEWS ≥ 6 as an independent predictor was 3.78 (1.94-7.09). CONCLUSIONS: In hospitalised COVID-19 patients, NEWS was an independent predictor of ICU transfer and in-hospital death. In daily practice, NEWS ≥ 6 at admission may help to identify patients who are at risk to deteriorate.

Prognosis of large vessel involvement in large vessel vasculitis.

OBJECTIVES: To assess prognosis factors and outcome of large vessel involvement (LVI) in large vessels vasculitis (LVV) patients. METHODS: Retrospective multicenter study of characteristics and outcomes of 417 patients with LVI including 299 Takayasu arteritis (TAK) and 118 Giant cell arteritis (GCA-LVI) were analyzed. Logistic regression analysis assessed prognosis factors in LVV patients. Outcome of LVI among TAK and GCA-LVI patients (ischemic complications, aneurysms complications, relapses and revascularization) were assessed. RESULTS: In multivariable analysis, stroke/transient ischemic attack [HR: 3.63 (1.46-9.04), p = 0.006] was independently associated with vascular complications in LVV. The 10-years aneurysm free survival was significantly lower [67% (48-93) vs 89% (84-95), p = 0.02] in GCA-LVI compare to TAK patients. The 5-years relapse free survival was significantly lower [47% (37-60) vs 69% (63-75), p < 0.001,] in GCA-LVI compare to TAK patients. The 10-years revascularization free survival was significantly lower [55% (48-64) vs 76% (59-99), p < 0.001] in TAK compare to GCA-LVI patients. After a median follow-up of 5 years, 16 (5.4%) TAK and 7 (5.9%) GCA-LVI patients died, mainly of aneurysm (26%) and ischemic complications (26%). CONCLUSION: This large nationwide cohort of LVI provided prognosis factors of vascular complications in LVV patients. TAK and GCA-LVI have different long-term outcome in term of aneurysm development, relapse and revascularization.

Consideration of coping strategies for patients suffering from systemic lupus erythematosus: reflection for a personalised practice of patient education.

OBJECTIVES: Systemic lupus erythematosus (SLE) is a chronic autoimmune multi-organ disease with an unpredictable course. SLE causes functional disability, changes in body appearance, and psychological distress. When faced with SLE, patients have to implement coping strategies. Therefore, the aim of this study was to describe patients' coping strategies, consider the implications for a personalised practice of patient education and evaluate patients' adherence to HCQ treatment. METHODS: One hundred and fifty-eight SLE patients receiving hydroxychloroquine (HCQ) treatment entered a prospective, non-comparative, longitudinal study aimed at describing patients' coping strategies and evaluating their adherence to the HCQ regimen. Coping strategies were evaluated using an abbreviated French version of the WCC-27 exploring 3 dimensions of coping: problem-centered coping, emotion-centered coping and search for social support. Adherence was assessed by the MASRI, the MMAS-8 and also objectively assessed by the patient's serum level of HCQ. Data collected at study entry also included disease activity: SLEDAI, and disease extent: SLICC damage index. The prevalence of anxious and depressive symptoms was evaluated with the HADS. Quality of life was evaluated using the LupusQoL questionnaire. RESULTS: Patients were clustered using an unsupervised hierarchical classification based on coping strategies. Four clusters of patients were individualised. The cluster of patients with low problem-centered coping, high emotion-centered coping and the lowest search for social support had worse quality of life and more psychological distress. We did not find any inter-cluster differences in terms of compliance to HCQ. CONCLUSIONS: Patients' knowledge is not the only parameter to consider for a personalised educational therapy: psychological parameters such as coping must also be considered to ensure the best possible quality of life. For educational therapy purposes, it is important not to group patients with the same coping style; heterogenous groups will enable patients to share their experiences and learn from the coping strategies of others.

Styloidogenic compression of the internal jugular vein, a new venous entrapment syndrome?

Internal jugular vein (IJV) thrombosis is mainly related to central venous catheter, malignancy, and ovarian hyperstimulation syndrome. We report a case of IJV thrombosis possibly related to IJV compression between the styloid process and the first cervical vertebra (C1) transverse process. To support this hypothesis, we perform radiological assessment of the IJV and examine its relationship with the styloid process and C1 transverse process in 34 controls. Our results showed a strong correlation between IJV diameter and styloid process-C1 transverse process distance. Compared to control subjects, our patient had a short styloid process-C1 transverse process distance, which suggests its involvement in IJV thrombosis.

Overall survival and mortality risk factors in Takayasu's arteritis: A multicenter study of 318 patients.

OBJECTIVE: To report the long term mortality in Takayasu arteritis (TA) and to identify prognosis factors. METHODS: We analyzed the causes of death and the factors associated with mortality in a cohort of 318 patients [median age at diagnosis was 36 [25-47] years and 276 (86%) patients were women] fulfilling American College of Rheumatology and/or Ishikawa criteria of TA. A prognostic score for death and vascular complications was elaborated based on a multivariate model. RESULTS: Among 318 TA patients, 16 (5%) died after a median [IQR] follow-up of 6.1 [2.8-13.0] years. The median age at death was 38 [25-47] years with 88% of women. Main causes of death included mesenteric ischemia (n = 4, 25%) and aortic aneurysm rupture (n = 4, 25%). The mortality rate at 5 and 10 years was of 1.9% and 3.9%, respectively. Caucasians (p = 0.049) and smokers (p = 0.002) TA patients were more likely to die. There was an increased mortality in TA (SMR with 95% confidence interval, 2.73 [1.69-4.22]) as compared to age and sex matched healthy controls. We defined high risk patients for death and vascular complications according to the presence of two of the following factors (i.e a progressive clinical course, thoracic aorta involvement and/or retinopathy). In the high risk TA group, the 5-year incidence of death and vascular complication was 48.5% compared to 21.6% (p = 0.001) in those with low risk. CONCLUSION: The overall mortality in our Takayasu cohort was 5% after a median follow-up of 6.1 years. We identified specific characteristics that distinguish TA patients at highest risk for death and vascular complications.

Different patterns and specific outcomes of large-vessel involvements in giant cell arteritis.

Large-vessel involvement (LVI) in giant cell arteritis (GCA) includes different clinical and imaging patterns that are rarely described separately at diagnosis and whose specific cardiovascular outcomes are unknown. We conducted a nationwide retrospective study and included GCA patients with LVI demonstrated on imaging at diagnosis between 2007 and 2017. We analyzed the prognosis of three different imaging patterns of LVI present at diagnosis, with some of them overlapping but with the first one present in all patients: 1) inflammation of the aorta and/or its branches; 2) dilation of the aorta; and 3) stenosis of the aortic branches. A control group of GCA patients without LVI was constituted. We included 183 patients with LVI and 105 controls without LVI. Altogether, among the 183 patients who all showed inflammation of the aorta and/or its main branches, concomitant aortic dilation and large-vessel stenosis were observed in 27 (15%) and 55 (30%) patients, respectively. During the follow-up period, new cardiovascular events occurred in 49% and 11% of LVI patients and controls, respectively (p < 0.0001). Inflammation of the aorta and/or its branches (HR: 3.42 [2.09-5.83], p < 0.0001) and large-artery stenosis (HR: 2.75 [1.80-4.15], p < 0.0001) were independent predictive factors of new cardiovascular events. Conversely, the use of an immunosuppressant besides corticosteroids was a protective factor against new cardiovascular events (HR: 0.44 [0.29-0.66], p < 0.0001) and the development of aortic dilation (HR: 0.43 [0.23-0.77], p = 0.005). This study suggests different forms of cardiovascular events according to the initial imaging pattern of LVI.

Clinical and immunological features of antiphospholipid syndrome in the elderly: a retrospective national multicentre study.

OBJECTIVE: APS mainly affects women who are of child-bearing age. We aimed to describe the clinical and immunological features of APS patients diagnosed after the age of 60. METHODS: The Elderly-Phospholipid study is a national, multicentre, retrospective study involving all APS (2006 Miyakis criteria) patients followed in five French tertiary university centres including four national referral lupus and APS centres. Clinical and serological data of patients in whom APS onset occurred after the age of 60 were analysed and compared with patients included in the Euro-Phospholipid cohort. RESULTS: Forty-four patients (30 women (68.2%); 68.7 (7) years at diagnosis; 72.7% of primary APS) were included in the Elderly-Phospholipid study. Stroke was the most common manifestation at diagnosis (38.6%) and during follow-up (11.4%). LA, aCL and anti-ß2-glycoprotein I antibodies were detected in 70.4%, 72.7% and 65.9% of patients, respectively; 43.2% of patients were triple-positive for aPL antibodies. All patients were treated with antithrombotic treatment including antiplatelet agents (31.8%) and/or oral anticoagulants (77.3%). Over a 5.3 (3.8) years follow-up, nine (20.5%) patients displayed a new arterial (n = 8) or venous (n = 1) thrombotic event. Only three (6.8%) patients developed major bleeding. As compared with Euro-Phospholipid APS patients (mean age of 34 (13) years at disease onset), patients in the Elderly-Phospholipid study were more frequently male (P < 0.05) and had a higher frequency of primary APS (<0.05), stroke (<0.0001) and LA (P < 0.05). CONCLUSION: APS patients with elderly onset share a distinct disease profile, with a higher frequency of LA, triple aPL positivity and arterial thrombosis.
