P4375Value of echocardiography to diagnose coronary arteries patterns in transposition of great arteries

Material and methods

Retrospective analysis of data in neonates diagnosed with TGA (isolated or associated with VSD). Preoperative echocardiographic (TTE) coronary artery pattern and surgical intraoperative reports (SURG) were compared. Mismatch between TTE and SURG, and its impact on perioperative outcome were assessed. Coronary patterns were classified in 4 groups: I= normal CA, II= CA with intramural course, III= CA loop, IV= CA loop and intramural segment.

Results

108 neonates who underwent arterial switch operation (ASO) for isolated TGA (67 cases) or TGA+VSD (41) were included in the study: 68 ranged in group I, 7 in group II, 32 in group III and 1 in group IV. Five patients died (4.6%), from coronary cause in 3. Survival rates were 96% at 1-month and 95.2% beyond. Intraoperative complications occurred in 10 cases. TTE and SURG CA diagnosis differed in 19 cases = 17.6% (mismatch). Diagnosis of CA anatomy differed in 4.4%, 42.8%, 37.5% and 100% of respectively groups I, II, III and IV. Mortality was 28.6% in group II (intramural CA) compared to 2.9% in group I, 3.1% in group III and 0% in group IV (p=0.002). Death rates was 15.8% if TTE/SURG mismatch and 2.2% if TTE and SURG were concordant (p=0.0108). Mortality in group II (intramural CA) increased up to 50% in case of mismach TTE/SURG versus 0% if concordance, and was similar in the other groups. Survival rates were 84.2% in TTE misdiagnosed CA anomalies compared to 97.6% if TTE assessment correlated with surgical reports. By multivariate analysis, groups II and III coronary anatomy were risk factors for mismatch between TTE and SURG (respectively p=0.008 and p=0.0005), and mismatch TTE/SURG was the only risk factor for perioperative mortality (p=0.045).

Conclusion

Echocardiography can accurately assess coronary artery anatomy in neonates with TGA. Intramural coronary course is often misdiagnosed. Missed diagnosis of coronary artery anomaly preoperatively may impact on perioperative mortality.

P4692Pronostic factors after arterial switch operation for transposition of the great arteries in children

Material and methods

Retrospective analysis of all ASO performed from 2000 to 2016 in patients with TGA. Demographics, clinical and biological data, surgical techniques, echocardiographic measurements, and outcomes were collected. Pronostic factors for mortality were assessed.

Results

364 patients were included (263 males). Antenatal diagnosis was made in 60,4%. Birth weight was 3207,5±511.2g, gestational age was 39.1±1.6weeks. Intramural coronary artery was present in 24 cases (6.6%). Long term follow-up was 9.2±4.8 years. Rashkind procedure was performed in 88.7% of the cases. Ventilatory support was needed in 56% and prostaglandins in 85% preoperatively. ASO occurred at the age of 7.44±6.26 days (1 to 56) and 5.6±4.6 days after admission. Bypass duration was 123.1±33.3mn. Overall and postoperative hospital stay were respectively 19.9±8.6 and 14.4±7.3 days. Survival rates were 95.3% at 1 month, 94.8% at 3, 6 and 12 months and 94.5% at 2.5 years and up to 18 years after surgery. Twenty patients died (5.5%): 17 early postoperatively (4.7%). Time from surgery to death was 64.2±207.9 days (0 to 919). Long-term events occurred in 49.6% of the patients: pulmonary stenosis, aortic or mitral regurgitation, residual shunt, coronary lesions (1.7%), arrhythmias (5.5%), cardiac failure. Freedom from late reintervention was 99.7%, 97.4%, 96.2% at 1, 3 and 6 months, 95.9%, 95%, 92.3% and 90.3% at respectively 1, 2, 5 and beyond 8 years after ASO. No Rashkind, postoperative ECMO support, delayed chest closure, bypass duration, troponine level and small birth weight were significant predictive factors of mortality (respectively p=0.006, p<0.0001, p=0.0007, p<0.0001, p=0.001 and p=0.044). Antenatal diagnosis, gender, gestational age, preoperative ventilatory support, prostaglandin infusion, and SpO2, coronary arteries anatomy or age at surgery were not associated with death.

Conclusion

This study showed that Rashkind procedure may have a favourable impact on prognosis of neonates with TGA. Postoperative ECMO support and troponine level, and small birth weight were associated with worse outcome.

A Randomised Trial of Subcutaneous Low Molecular Weight Heparin (CY 216) Compared with lntravenous Unfractionated Heparin in the Treatment of Deep Vein Thrombosis

The standard treatment of deep vein thrombosis is given by continuous intravenous infusion of unfractionated heparin. This entails hospitalisation, nursing care, immobility and repeated laboratory tests (e.g. activated partial thromboplastin time [APTT], platelet count). In addition approximately 10% of patients suffer major haemorrhages. The potential advantages of a low molecular weight heparin (CY 216) given subcutaneously were explored in a randomised trial with blind quantitative evaluation of venograms. The study included 166 patients and both “therapeutic efficacy” and “intention to-treat” analyses showed that subcutaneous CY 216 in fixed doses based only on body weight was more effective on the Arnesen and Marder phlebographic scores than continuous i. v. standard heparin with daily dose adjustment according to results of coagulation tests. There was no increase in the risks of pulmonary embolism, haemorrhage or clot extension.

Double-Blind, Randomized Comparison of Systemic Continuous Infusion of 0.25 Versus 0.50 mg/kg/24 h of Alteplase over 3 to 7 Days for Treatment of Deep Venous Thrombosis in Heparinized Patients: Results of the European Thrombolysis with rt-PA in Venous Thrombosis (ETTT) Trial

Thirty-two patients with acute, proximal-vein thrombosis were treated with heparin and alteplase (0.25 versus 0.5 mg/kg/24 h during 3-7 days) in a randomized, double-blind, multicenter, European (ETTT) trial. The treatment resulted in a decrease of the venographic Marder’s score from 18 (6-25) to 13 (2-24) units (median, range) in Group I (0.25 mg/kg/24 h, n = 15, median decrease 3.0, p = 0.32) and from 17.5 (3-33) to 15.5 (0-27) in Group II (0.5 mg/kg/24 h, n = 16, median decrease 4.0, p = 0.23). Comparison of the sequential venograms could be performed in 14 cases of Group I and in 15 cases in Group II. A minority of patients showed substantial partial recanalization of the initially obstructed veins on the control venogram (one in each treatment group) and most of the control venograms showed

Thus, the results of the ETTT trial show that the used low dosages of alteplase administered intravenously over 3-7 days in heparinized patients cannot be recommended as a treatment for patients with deep venous thrombosis of lower limbs and/or pelvis. Further studies are needed to define a more suitable dosage regimen of alteplase in this indication.

Use of calibrated automated thrombinography ± thrombomodulin to recognise the prothrombotic phenotype

There is currently no validated method to detect a prothrombotic phenotype. The question remains, can tissue factor (TF) induced thrombin generation (TG), as measured with the calibrated automated thrombinography (CAT) technique, according to Hemker et al., recognise a prothrombotic state either as such, or when the activated proteinC (APC)-system is boosted with thrombomodulin (TM)? We determined the normal range of CAT-TG ± TM in a group of 71 healthy blood donors, in 11 healthy women using oral contraceptives (OC), and in 89 patients with a history of venous thromboembolism (VTE), divided into a group of 50 in whicha prothrombotic risk factor could be found (VTEprf+) and 39 others (VTEprf-). The endogenous thrombin potential (ETP) in the OC, VTEprf+ and VTEprf-group was significantly higher than for the controls. In the presence of TM, the differences were significantly higher than in its absence. The VTEprf+ group had a higher ETP, ± TM than the VTEprf group. In conclusion,TG, measured with the CAT technique in the presence of TM is capable of detecting the prothrombotic phenotype with a high sensitivity of 0.93 (95% confidence limits 0.82–0.99).

Bone marrow involvement in systemic lupus erythematosus

BACKGROUND

Besides peripheral cytopenias, bone marrow abnormalities, such as fibrosis, pure red cell aplasia and aplastic anemia have been reported in patients with systemic lupus erythematosus (SLE), suggesting that bone marrow may be a 25 target organ in SLE.

AIM

Our objective was to describe this bone marrow involvement.

METHODS

This registry is a nationwide retrospective study. Centers provided data concerning medical history, SLE manifestations, type of hematologic disorder, treatments and outcome. Bone marrow aspirations and/or biopsies were transferred for centralized review.

RESULTS

Thirty patients from 19 centers were included. Central hematologic manifestations comprised bone marrow fibrosis (n = 17; 57%), pure red cell aplasia (n = 8; 27%), myelodysplastic syndrome (n = 3; 10%), aplastic anemia and agranulocytosis (n = 1; 3% each). Bone marrow involvement was diagnosed concomitantly with SLE in 12 patients. Bone marrow biopsies showed fibrosis in 19 cases, including one case of pure red cell aplasia and one case of agranulocytosis and variable global marrow cellularity. Treatments included corticosteroids (90%), hydroxychloroquine (87%), rituximab (33%), intravenous immunoglobulins (30%), mycophenolate mofetil (20%) and ciclosporine (20%). After a median follow-up of 27 months (range: 1-142), 24 patients manifested complete improvement. No patient died.

CONCLUSIONS

This registry comprises the largest series of SLE patients with bone marrow involvement. It demonstrates the strong link between SLE and bone marrow fibrosis. Patients with atypical or refractory cytopenia associated with SLE should undergo bone marrow examination to enable appropriate, and often effective, treatment. Long-term prognosis is good.

Personalized thromboprophylaxis using a risk score for the management of pregnancies with high risk of thrombosis: a prospective clinical study

Essentials Pregnancy is a risk factor for thrombosis. Management of thrombosis risk in pregnancy remains a challenge. Prophylaxis needs to be personalized. Our score may be a helpful tool for the management of pregnancies at high risk of thrombosis.

SUMMARY

Background Patients with thrombophilia and/or a history of venous thromboembolism (VTE) are at risk of thrombosis during pregnancy. A risk score for pregnancies with an increased risk of VTE was previously described by our group (Lyon VTE score). Objectives The aim of this prospective study was to assess the efficacy and safety of our score-based prophylaxis strategy in 542 pregnancies managed between 2005 and 2015 in Lyon University Hospitals. Patients/Methods Of 445 patients included in the study, 36 had several pregnancies during the study period. Among these 445 patients, 279 had a personal history of VTE (62.7%), 299 patients (67.2%) had a thrombophilia marker, and 131 (29.4%) thrombophilic women had a personal history of VTE. During pregnancy, patients were assigned to one of three prophylaxis strategies according to the risk scoring system. Results In the antepartum period, low molecular weight heparin (LMWH) prophylaxis was prescribed to 64.5% of patients at high risk of VTE. Among them, 34.4% were treated in the third trimester only, and 30.1% were treated throughout pregnancy. During the postpartum period, all patients received LMWH for at least 6 weeks. Two antepartum-related VTEs (0.37%; one with a score of < 3 and the other with a score of > 6) and four postpartum-related VTEs (0.73%; three with scores of 3-5 and one with a score of > 6) occurred. No case of pulmonary embolism was observed during the study period. The rate of bleeding was 0.37%. No serious bleeding requiring transfusions or surgery occurred during the study period. Conclusion The use of a risk score may provide a rational decision process to implement safe and effective antepartum thromboprophylaxis in pregnant women at high risk of VTE.

The Clinical Relevance of Antifibrillarin (anti-U3-RNP) Autoantibodies in Systemic Sclerosis

Systemic sclerosis (SSc) is a heterogeneous autoimmune disease associated with several antinuclear autoantibodies useful to diagnosis and prognosis. The aim of the present multicentric study was to determine the clinical relevance of antifibrillarin autoantibodies (AFA) in patients with SSc. The clinical features of 37 patients with SSc positive for AFA (AFA+) and 139 SSc patients without AFA (AFA-) were collected retrospectively from medical records to enable a comparison between AFA- and AFA+ patients. Antifibrillarin autoantibodies were screened by an indirect immunofluorescence technique using HEp2 cells and identified by an in-house Western blot technique and/or an EliA test. Comparing AFA+ and AFA- patients, AFA+ patients were significantly younger at disease onset (36.9 versus 42.9; P = 0.02), more frequently male (P = 0.02) and of Afro-Caribbean descent (65% versus 7.7%; P < 0.001). At diagnosis, the Rodnan skin score evaluating the cutaneous manifestations was higher (13.3 versus 8.7; P = 0.01) and myositis was also more common in the AFA+ group (31.4% versus 12.2%; P < 0.01). Patients with AFA+ were not associated with diffuse cutaneous SSc or with lung involvement and no difference in survival was observed. Antifibrillarin autoantibodies are associated with patients of Afro-Caribbean origin and can identify patients with SSc who are younger at disease onset and display a higher prevalence of myositis.

Factors associated with Clostridium difficile infection: A nested case-control study in a three year prospective cohort

BACKGROUND

Clostridium difficile infection (CDI) is a serious medical condition that is associated with substantial morbidity and mortality. Identification of risk factors associated with CDI and prompt recognition of patients at risk is key to successfully preventing CDI.

METHODS

A 3-year prospective, observational, cohort study was conducted in a French university hospital and a nested case-control study was performed to identify risk factors for CDI. Inpatients aged 18 years or older, suffering from diarrhea suspected to be related to CDI, were asked to participate.

RESULTS

A total of 945 patients were included, of which 233 cases had a confirmed CDI. CDI infection was more common in men (58.4%) (P = 0.04) compared with patients with diarrhea not related to C. difficile. Previous hospitalization (P < 0.001), prior treatment with antibiotics (P = 0.001) or antiperistaltics (P = 0.002), liver disease (P = 0.003), malnutrition (P < 0.001), and previous CDI (P < 0.001) were significantly more common in patients with CDI. Multivariate logistic regression analysis showed that exposure to antibiotics in the last 60 days (especially third generation cephalosporins and penicillins with β-lactamase inhibitor), chronic renal or liver disease, malnutrition or previous CDI, were associated with an independent high risk of CDI. Age was not related with CDI.

CONCLUSIONS

This study showed that antibiotics and some comorbid conditions were predictors of CDI. Patients at high risk of acquiring CDI at the time of admission may benefit from careful monitoring of antibiotic prescriptions and early attention to infection control issues. In future, these "high-risk" patients may benefit from novel agents being developed to prevent CDI.

Multiple arterial thromboses in a patient with primary antiphospholipid syndrome receiving a bromocriptine therapy

We report a patient with a previously known primary antiphospholipid syndrome who had life threatening multiple arterial thromboses. The patient experienced a myocardial infarction with intraventricular thrombi under bromocriptine therapy in the puerperium, despite prophylactic low molecular weight heparin therapy. In this patient, no microvascular involvement was identified, thus eliminating the diagnosis of catastrophic antiphospholipid syndrome. Arterial thromboses may be explained by peripheral emboli originating from the intraventricular thrombi. This case emphasizes the necessity of a careful evaluation of the risk-benefit balance of bromocriptine therapy in patients with arterial risk factors. It also emphasizes the need for a correct diagnosis of catastrophic antiphospholipid syndrome allowing to limit the prescription of aggressive therapies.

Rituximab versus azathioprine for ANCA-associated vasculitis maintenance therapy: impact on global disability and health-related quality of life

OBJECTIVES

To investigate the effects on health-related quality of life (HRQOL) and functional capability of rituximab vs azathioprine for ANCA-associated vasculitis (AAV) maintenance therapy.

METHODS

In a 24-month phase III randomised-controlled trial, 115 patients over time received rituximab or azathioprine for AAV maintenance therapy. Mean changes of 36-item Short-form Health Survey (SF-36) and Health Assessment Questionnaire (HAQ) scores from baseline were analysed.

RESULTS

Mean improvements of HAQ scores, from baseline to month 24 were significantly better for the rituximab (0.16 points lower) than the azathioprine group (p=0.038). As demonstrated by SF-36, study patients' baseline HRQOL was significantly impaired compared with age- and sex-matched US norms. At month 24, mean changes from baseline of SF-36 physical component score tended to be better for the rituximab group (+3.95 points, p=0.067) whereas mean changes from baseline of the SF-36 mental component score were significantly better for the azathioprine group (+4.23 points, p=0.041).

CONCLUSIONS

Azathioprine-treated patients' for AAV maintenance therapy showed a decline in physical abilities when compared to RTX at M24 in the MAINRITSAN trial.

Observational Study of a French and Belgian Multicenter Cohort of 23 Patients Diagnosed in Adulthood With Mevalonate Kinase Deficiency

The aim of this study was to describe the clinical and biological features of Mevalonate kinase deficiency (MKD) in patients diagnosed in adulthood. This is a French and Belgian observational retrospective study from 2000 to 2014. To constitute the cohort, we cross-check the genetic and biochemical databases. The clinical, enzymatic, and genetic data were gathered from medical records. Twenty-three patients were analyzed. The mean age at diagnosis was 40 years, with a mean age at onset of symptoms of 3 years. All symptomatic patients had fever. Febrile attacks were mostly associated with arthralgia (90.9%); lymphadenopathy, abdominal pain, and skin lesions (86.4%); pharyngitis (63.6%); cough (59.1%); diarrhea, and hepatosplenomegaly (50.0%). Seven patients had psychiatric symptoms (31.8%). One patient developed recurrent seizures. Three patients experienced renal involvement (13.6%). Two patients had angiomyolipoma (9.1%). All but one tested patients had elevated serum immunoglobulin (Ig) D level. Twenty-one patients had genetic diagnosis; most of them were compound heterozygote (76.2%). p.Val377Ile was the most prevalent mutation. Structural articular damages and systemic AA amyloidosis were the 2 most serious complications. More than 65% of patients displayed decrease in severity and frequency of attacks with increasing age, but only 35% achieved remission. MKD diagnosed in adulthood shared clinical and genetic features with classical pediatric disease. An elevated IgD concentration is a good marker for MKD in adults. Despite a decrease of severity and frequency of attacks with age, only one-third of patients achieved spontaneous remission.

Hemophagocytic Lymphohistiocytosis in Intensive Care Unit: A 71-Case Strobe-Compliant Retrospective Study

Hemophagocytic lymphohistiocytosis (HLH) is a critical condition that may lead to organ failure and early death. The aim of this retrospective observational study was to describe a cohort of HLH patients admitted to intensive care unit (ICU) and investigate the risk factors of early death.A positive HLH diagnosis was defined by an HScore ≥ 169. Univariate and multivariate analyses were carried out to investigate hospital and 28-day mortality risk factors. Between January 2002 and July 2014, 71 HLH cases were seen at our institution.The overall 28-day mortality (start at ICU admission) and hospital mortality were 38% and 68%, respectively. The factors associated with increased 28-day mortality were the sequential organ failure assessment score at ICU admission (P < .001) and advance in age (P = 0.03). The factors associated with increased hospital mortality were a high sequential organ failure assessment score at ICU admission (P < 0.01), advance in age (P = 0.04), and the presence of lymphoma-related HLH or HLH of unknown origin (P < 0.01).Organ failure overtops the classical early-death risk factors in adult ICU-admitted HLH patients. This failure and the subsequent early death may be prevented by timely specific cytotoxic therapies and the control of the underlying disease.

[Association of lymphoma and granulomatosis: A case series]

PURPOSE

The sarcoidosis-lymphoma syndrome is a recognised entity. However, the presence of granulomas in patients with a haematological disease should not lead too easily to a diagnosis of sarcoidosis. The presence of granulomatous lesions during the follow-up of these patients raises diagnostic and therapeutic issues.

METHODS

We included 25 patients followed by the department of haematology in a French hospital (Centre Léon-Bérard). These patients presented with granulomatous lesions. Patients with a history of sarcoidosis were excluded. We report the type of haematological disease, the time of onset of the granulomatous disease compared to that of lymphoma, associated symptoms, aetiology and outcome. Patients were divided into three groups according to the time of onset of the granulomatous lesions.

RESULTS

Granulomatous lesions appeared before the haematological disease in 4 cases, was concomitant in 8 cases and appeared later in 13 remaining cases. The two main subtypes of lymphoma encountered were: diffuse large cell lymphoma (36%) and Hodgkin's lymphoma (28%). Granulomatous lesions were related to the progression of the hematological disease in 11 cases, to sarcoidosis in 4 cases, to infection in 3 cases, to drug allergy in one case, to inflammatory bowel disease in one case, to granuloma annulare in one case and was isolated in 4 cases (no identified etiology). In the group where granulomas appeared after the haematological disease, mean SUV was 11 for the haematological disease versus 6.4 for granulomas.

CONCLUSION

Granulomatous diseases in lymphomas can be due to various aetiologies: infection, reaction to the haematological disease, or systemic sarcoidosis. It is an important challenge for clinicians, who can miss the diagnosis of lymphoma and or conclude to a treatment failure or a relapse. Computed tomography scan (CT-scan) or (18)F-deoxyglucose-positron emission tomography scan can help establish a diagnosis but do not replace biopsy.

Validity of the global anti-phospholipid syndrome score to predict thrombosis: a prospective multicentre cohort study

OBJECTIVE

To investigate the validity of the global APS score (GAPSS) to predict thrombosis in patients with autoimmune diseases.

METHODS

This prospective cohort study included consecutive patients with aPL or SLE. aPL, aPS-PT and GAPSS were determined. A Cox proportional hazards model assessed the validity of GAPSS and identified other potential independent predictors of thrombosis.

RESULTS

One hundred and thirty-seven patients [43.5 (s.d. 15.4) years old; 107 women] were followed up for a mean duration of 43.1 (s.d. 20.7) months. Mean GAPSS was significantly higher in patients who experienced a thrombotic event compared with those without [10.88 (s.d. 5.06) vs 8.15 (s.d. 5.31), respectively, P = 0.038]. In univariate analysis, age [hazard ratio (HR) = 1.04 (95% CI 1.01, 1.08)] and GAPSS above 16 [HR = 6.86 (95% CI 1.90, 24.77)] were each significantly associated with thrombosis during follow-up, while history of arterial thrombosis [HR = 2.61 (95% CI 0.87, 7.82)] failed to reach significance. Among aPL assays, IgG aPS/PT--a component of the GAPSS--was significantly associated with thrombosis [HR = 2.95 (95% CI 1.02, 8.51)]. In multivariate analysis, GAPSS above 16 remained the only significant predictor of thrombosis [HR = 6.17 (95% CI 1.70, 22.40)].

CONCLUSION

This first external validation study confirmed that GAPSS can predict thrombosis in patients with aPL and associated autoimmune diseases.

Treatment of systemic necrotizing vasculitides in patients aged sixty-five years or older: results of a multicenter, open-label, randomized controlled trial of corticosteroid and cyclophosphamide-based induction therapy

OBJECTIVE

To investigate a new therapeutic strategy, with rapid corticosteroid dose tapering and limited cyclophosphamide (CYC) exposure, for older patients with systemic necrotizing vasculitides (SNVs; polyarteritis nodosa [PAN], granulomatosis with polyangiitis [Wegnener's] [GPA], microscopic polyangiitis [MPA], or eosinophilic GPA [Churg-Strauss] [EGPA]).

METHODS

A multicenter, open-label, randomized controlled trial comprising patients ≥65 years old and newly diagnosed as having SNV was conducted. The experimental treatment consisted of corticosteroids for ∼9 months and a maximum of six 500-mg fixed-dose intravenous (IV) CYC pulses, every 2-3 weeks, then maintenance azathioprine or methotrexate. The control treatment included ∼26 months of corticosteroids for all patients, combined with 500 mg/m(2) IV CYC pulses, every 2-3 weeks until remission, then maintenance for all patients with GPA or MPA and for those with EGPA or PAN with a Five-Factors Score (FFS) of ≥1. Randomization used a 1:1 ratio computer-generated list and was performed centrally with sealed opaque envelopes. The primary outcome measure was ≥1 serious adverse event (SAE) occurring within 3 years of followup. Secondary outcome measures included remission and relapse rates.

RESULTS

Among the 108 patients randomized, 4 were excluded (early consent withdrawal or protocol violation). Mean ± SD age at diagnosis was 75.2 ± 6.3 years. Analysis at 3 years included 53 patients (21 GPA, 21 MPA, 8 EGPA, and 3 PAN) in the experimental arm and 51 patients (15 GPA, 23 MPA, 6 EGPA, and 7 PAN) in the conventional arm. In total, 32 (60%) versus 40 (78%) had ≥1 SAE (P = 0.04), most frequently infections; 6 (11%) versus 7 (14%) failed to achieve remission (P = 0.71); 9 (17%) versus 12 (24%) died (P = 0.41); and 20 (44%) of 45 versus 12 (29%) of 41 survivors in remission experienced a relapse (P = 0.15).

CONCLUSION

For older SNV patients, an induction regimen limiting corticosteroid exposure and with fixed low-dose IV CYC pulses reduces SAEs in comparison to conventional therapy, and does not affect the remission rate. Three-year relapse rates remain high for both arms.

Impairment of quality of life in patients with antiphospholipid syndrome

OBJECTIVES

Health-related quality of life (HRQoL) has not been fully explored in antiphospholipid syndrome (APS); therefore, we compared HRQoL between APS patients and the general population and assessed the impact of thromboembolic history.

METHODS

HRQoL was measured in a multicentre cohort study by the Medical Outcomes Study Short-Form 36 (MOS-SF-36) questionnaire. HRQoL scores were compared to the French general population norms. Factors significantly associated with an impaired HRQoL were identified.

RESULTS

A total of 115 patients with aPL and/or systemic lupus erythematosus (SLE) were included (mean age 42.7 ± 14.1 years old, 86 women). In 53 patients APS was diagnosed. Compared to general population norms, patients with APS had an impaired HRQoL. SLE-associated APS patients had the worst HRQoL scores (physical component summary (PCS)=40.8 ± 10.6; mental component summary (MCS)=40.6 ± 16.5) in comparison with SLE or aPL patients without thromboembolic history. In APS patients, history of arterial thrombosis significantly impaired HRQoL (PCS score: 42.2 ± 9.4 vs 49.2 ± 8.5; MCS score: 33.9 ± 13.7 vs 44.6 ± 10.3).

CONCLUSION

Compared to the general population, APS patients experienced a lower HRQoL. In these patients, a history of arterial thrombosis significantly impaired HRQoL. Therefore, measurements of HRQoL should be included in APS patient management to assess the burden of the disease from a patient's perspective and to provide patients with the support they need.

[Screening and management of cardiovascular risk factors in systemic lupus erythematosus: Recommendations for clinical practice based on the literature and expert opinion]

PURPOSE

To develop French recommendations about screening and management of cardiovascular risk factors in systemic lupus erythematosus (SLE).

METHODS

Thirty-nine experts qualified in internal medicine, rheumatology and nephrology have selected recommendations from a list developed based on evidence from the literature. For each recommendation, the level of evidence and the level of agreement among the experts were specified.

RESULTS

Experts recommended an annual screening of cardiovascular risk factors in SLE. Statins should be prescribed for primary prevention in SLE patients based on the level of LDL-cholesterol and the number of cardiovascular risk factors, considering SLE as an additional risk factor. For secondary prevention, experts have agreed on an LDL-cholesterol target of <0.7 g/L. Hypertension should be managed according to the 2013 European guidelines, using renin-angiotensin system blockers as first line agents in case of renal involvement. Aspirin can be prescribed in patients with high cardiovascular risk or with antiphospholipid antibodies.

CONCLUSION

These recommendations about the screening and management of cardiovascular risk factors in SLE can be expected to improve clinical practice uniformity and, in the longer term, to optimize the management of SLE patients.

Rituximab versus azathioprine for maintenance in ANCA-associated vasculitis

BACKGROUND

The combination of cyclophosphamide and glucocorticoids leads to remission in most patients with antineutrophil cytoplasm antibody (ANCA)-associated vasculitides. However, even when patients receive maintenance treatment with azathioprine or methotrexate, the relapse rate remains high. Rituximab may help to maintain remission.

METHODS

Patients with newly diagnosed or relapsing granulomatosis with polyangiitis, microscopic polyangiitis, or renal-limited ANCA-associated vasculitis in complete remission after a cyclophosphamide-glucocorticoid regimen were randomly assigned to receive either 500 mg of rituximab on days 0 and 14 and at months 6, 12, and 18 after study entry or daily azathioprine until month 22. The primary end point at month 28 was the rate of major relapse (the reappearance of disease activity or worsening, with a Birmingham Vasculitis Activity Score >0, and involvement of one or more major organs, disease-related life-threatening events, or both).

RESULTS

The 115 enrolled patients (87 with granulomatosis with polyangiitis, 23 with microscopic polyangiitis, and 5 with renal-limited ANCA-associated vasculitis) received azathioprine (58 patients) or rituximab (57 patients). At month 28, major relapse had occurred in 17 patients in the azathioprine group (29%) and in 3 patients in the rituximab group (5%) (hazard ratio for relapse, 6.61; 95% confidence interval, 1.56 to 27.96; P=0.002). The frequencies of severe adverse events were similar in the two groups. Twenty-five patients in each group (P=0.92) had severe adverse events; there were 44 events in the azathioprine group and 45 in the rituximab group. Eight patients in the azathioprine group and 11 in the rituximab group had severe infections, and cancer developed in 2 patients in the azathioprine group and 1 in the rituximab group. Two patients in the azathioprine group died (1 from sepsis and 1 from pancreatic cancer).

CONCLUSIONS

More patients with ANCA-associated vasculitides had sustained remission at month 28 with rituximab than with azathioprine. (Funded by the French Ministry of Health; MAINRITSAN ClinicalTrials.gov number, NCT00748644; EudraCT number, 2008-002846-51.).

Myocarditis in adult-onset still disease

This study highlights the clinical features, treatments, and outcomes of the rare myocarditis in adult-onset Still disease (AOSD). Among a case series of 57 patients fulfilling either Yamaguchi or Fautrel AOSD criteria and seen between 1998 and 2010, we identified 4 cases of myocarditis. From a comprehensive literature review, we collected 20 additional cases of myocarditis-complicated AOSD. The characteristics of patients with myocarditis were compared with those of AOSD patients without myocarditis.In these 24 myocarditis-complicated AOSD cases, myocarditis occurred early and was present at AOSD onset in 54% of the cases. Myocarditis was often symptomatic (96% of patients) with nonspecific electrocardiographic abnormalities (79% of patients) and a left ventricle ejection fraction ≤50% (67% of patients). Cardiac magnetic resonance imaging and endomyocardial biopsies showed features consistent with myocarditis in 4 patients and a mononuclear interstitial inflammatory infiltrate in 4 others. Steroids alone were effective in 50% of patients with myocarditis. Intravenous immunoglobulins, methotrexate, and tumor necrosis factor-α-blockers were also prescribed and often found effective. Only 1 patient died from cardiogenic shock. Patients with myocarditis-complicated AOSD were younger and more frequently male than patients with AOSD alone. Pericarditis was more frequent in the myocarditis group; white blood cell count, polymorphonuclear cell count, and serum ferritin levels were also higher.Myocarditis is a potentially life-threatening complication of AOSD but responds positively to steroids and other immunomodulatory drugs. Its prognosis remains good (only 1 death occurred), but the condition requires close monitoring of heart function.

Long-term effectiveness and safety of interleukin-1 receptor antagonist (anakinra) in Schnitzler's syndrome: a French multicenter study

The aim of this study is to assess the long-term effectiveness and safety of IL1Ra in Schnitzler syndrome (SchS). Between 2010 and 2012, we performed a nationwide survey among French internal medicine departments to identify SchS patients. We retrospectively analyzed the long-term efficacy and safety of IL1Ra and the outcome of patients that did not receive this treatment. Forty-two patients were included in the study, 29 of whom received IL1Ra. The mean age at disease onset was 59.9years. Disease manifestations included urticaria (100%), fever (76%), bone/joint pain (86%), bone lesions (76%), anemia (67%), and weight loss (60%). The monoclonal gammopathy was overwhelmingly IgM kappa (83%). The mean follow-up was 9.5years (range: 1.6-35). Two patients developed Waldenström's macroglobulinemia and one developed AA amyloidosis. All of the 29 patients who received IL1Ra responded dramatically. After a median follow-up of 36months (range: 2-79), the effectiveness remained unchanged. All patients remained on anti-IL-1 therapy. Twenty-four patients (83%) went into complete remission and five (17%) into partial remission. Three patients experienced grade 3-4 neutropenia. Six patients developed severe infections. No lymphoproliferative diseases occurred while on IL1Ra. When last seen, all patients without anakinra had an active disease with variable impact on their quality of life. Their median corticosteroids dosage was 6mg/d (range: 5-25). IL1Ra is effective in SchS, with a sharp corticosteroid-sparing effect. Treatment failures should lead to reconsider the diagnosis. Long-term follow-up revealed no loss of effectiveness and a favorable tolerance profile. The long-term effects on the risk of hemopathy remain unknown.

[Auto-immune diseases and cancers. Second part: auto-immune diseases complicating cancers and their treatment]

Autoimmune diseases may reveal or occur during the course of a neoplasia or its treatment. Autoimmune cytopenia, especially haemolytic anaemia, is common in lymphoproliferative disorders such as chronic lymphoid leukemia. The link between cancer and myositis is well established. Dermatomyositis is associated with an increased relative risk of cancer of 3.4 to 4.4. A combination of detection of antibodies against p155 and TEP-computed tomography may be the best approach to ascertain the presence of occult malignancy in patients with dermatomyositis. A cutaneous or a systemic vascularitis may reveal a cancer, most often a haematological malignancy such as hairy cell leukemia. Paraneoplastic polyarthritis have been described in particular with adenocardinoma of the lungs. Underlying neoplasia should be considered in male smokers patients with new onset polyarthritis and poor health status. The prevalence of autoimmune conditions in myelodysplastic syndromes is 10 to 30%. Vasculitis and relapsing polychondritis are the most commonly reported manifestations. Immune manifestations can also be related to treatment. The most common treatment complications are autoimmune haemolytic anaemia with fludarabine and thyroiditis related to interferon and cervical radiotherapy.
