Outcome and prognosis of isolated carotid vasculitis.

OBJECTIVE: To assess the prognosis and outcome of patients with isolated carotid vasculitis. METHODS: We performed a retrospective multicenter study of 36 patients (median age at diagnosis was 37 [IQR 27-45] years and 11 [31 %] patients were men) with initial presentation as isolated carotid vasculitis. Study endpoints included vascular complications, relapses, and progression to large vessel vasculitis (i.e. Giant cell arteritis or Takayasu). RESULTS: The most frequent involvement was the left internal carotid artery (39 %), and 81 % had stenosis. After a median follow-up of 32 months [IQR 12-96], 21 (58 %) patients had a vascular event, including 31 % of new onset vascular lesions and 25 % of stroke/transient ischemic attack. Patients with stroke had less carotidynia at diagnosis (33 % vs 74 %, p = 0.046), higher significant carotid stenosis (i.e. > 50 %) (89 % vs. 30 %, p = 0.026) and higher severe carotid stenosis (i.e. >70 %) (67 % vs 19 %, p = 0.012), compared to those without stroke. Twenty (52 %) patients experienced relapses. High CRP at diagnosis was associated with relapses (p = 0.022). At the end of follow-up, 21 (58 %) patients were classified as having Takayasu arteritis, 13 (36 %) as isolated carotid vasculitis, and two (6 %) as giant cell arteritis. CONCLUSION: Carotid vasculitis may occur as a topographically limited lesion and is associated with significant rate of vascular complications.

[Attitude and beliefs of healthcare workers toward influenza vaccination in Internal Medicine: A cross-sectional survey]. / Attitude et croyances du personnel soignant en Médecine Interne vis-à-vis de la vaccination antigrippale saisonnière : étude transversale descriptive.

INTRODUCTION: The rate of vaccination in HCWs in France remains low. We aimed to analyze the attitude and beliefs of HCWs toward influenza vaccination in Internal Medicine wards. METHODS: We conducted a cross-sectional survey of HCWs in the departments of Internal Medicine of two tertiary hospitals in France. An anonymous questionnaire designed for this study was used to collect demographic, health beliefs and attitudes, and medical knowledge related to the influenza and influenza vaccine. The survey started shortly prior the 2019 influenza season. RESULTS: The surveys were completed by 158 (29[18-62] years-old ; 75.9% female ; 69.6% non-medical workers) of 187 (84.5%) HCWs. Overall, influenza vaccination coverage rate was 50.6% (n=80/158). Higher vaccination coverage was found in physician and in HCWs who had a better knowledge about the virus transmission. The reason to fulfill vaccination recommendations was to protect the patients, their relatives and themselves for more than 80% of HCWs compliant to vaccination recommendation. More than a third of HCWs (n=59/158; 37.3%) refused to be vaccinated or hesitated. Among them, 12 (12/59, 20.3%) believed that influenza vaccine could cause flu. The main reasons for reluctant HCWs to eventually accept to be vaccinated were a mandatory vaccination program and the demonstration of a better vaccine efficacy to prevent the disease. CONCLUSION: Influenza vaccination coverage among HCWs in Internal Medicine remains low. Education campaigns targeting in priority nurses and nurse assistants is mandatory to improve the compliance of HCWs to vaccination recommendation.

[Update on Susac syndrome]. / Actualités dans le syndrome de Susac.

Susac syndrome is a rare disease affecting mainly young women, characterized by a microangiopathy limited to the cerebral, retinal, and cochlear vessels. Although the pathophysiology of Susac syndrome is not yet fully elucidated, recent advances favour a primitive vasculitis affecting the cerebral, retinal and cochlear small vessels. Susac syndrome must be recognized in the presence of the pathognomonic clinical triad associating: 1/subacute encephalopathy with unusual headache and pseudopsychiatric features associated with diffuse white matter, grey matter nuclei and specifically corpus callosum lesions on brain MRI; 2/eye involvement that may be pauci-symptomatic, with occlusions of the branches of the central artery of the retina at fundoscopy and arterial wall hyperfluorescence on fluorescein angiography; and 3/cochleo-vestibular damage with hearing loss predominating at low frequencies on the audiogram. Relapses are frequent during an active period lasting approximately 2 years. Eventually, the disease resolves but isolated retinal arterial wall hyperfluorescence without new occlusions may recur, which should not lead to treatment intensification. First-line treatment consists of a combination of anti-aggregants and high dose corticosteroids. In refractory patients or in case of relapse, immunomodulatory molecules such as intravenous immunoglobulins or immunosuppressive drugs such as mycophenolate mofetil, cyclophosphamide or rituximab should be started. Unfortunately, sequelae-mostly hearing loss- remain frequent in these young patients.

[Post-acute and rehabilitation care in young patients with multiple comorbidities: An observational study]. / Soins de suite et réadaptation (SSR) de Médecine Interne pour sujets jeunes polypathologiques : étude observationnelle d'une structure pilote.

INTRODUCTION: A unique structure devoted to post-acute and rehabilitation care for patients under 75 with multiple comorbidities has been created within the Department of Internal Medicine, Bichat Hospital, Paris. We aim to report on demographic factors, clinical characteristics and outcomes of patients hospitalized in this pilot structure. METHODS: All consecutive adult patients admitted between May 2017 and May 2018 were retrospectively reviewed. RESULTS: Analysis was performed on 61 (61 [24-75] years-old) admitted patients. The median length of hospital stays was 108 [13-974] days. At admission, the median Charlson comorbidity index was 6 [0-12] predicting a 10-year survival of 21 [0-99]%. Most patients were unemployed (83.6%) and had very low-income (< national minimum wage in 65.6% of cases). At hospital discharge, most patients (85.4%) were able to return home. The complete resolution of health problems occurred in most cases (65.6%) and was associated with a lower probability of both hospital readmission and death 1-year after discharge. CONCLUSION: The structure served a high percentage of patients with major and complex health needs but limited access to care due to individual disabilities, low-income and underinsured status. However, despite major health disorders, functional limitations, and vulnerability, admission improved patient outcomes and reduced excess hospital readmissions in most cases.

[Haemothorax revealing thoracic endometriosis]. / Hémothorax spontané révélant une endométriose pleurale.

INTRODUCTION: Thoracic endometriosis (TE) is a rare disorder affecting women during their reproductive years. Manifestations of TE include pneumothorax and haemothorax. Treatment is based on surgical and hormonal therapy that aims at eradicating existing endometrial thoracic plaques and to prevent reseeding from pelvic endometriosis. CASE REPORT: We report the case of a 36 year-old young woman presenting thoracic endometriosis revealed by a recurring spontaneous, large and isolated right haemothorax. Diagnosis, pathogeny and treatment are discussed. CONCLUSION: Thoracic endometriosis needs to be considered as a cause of haemothorax in women of childbearing age.

Soluble CD163 is a biomarker for accelerated atherosclerosis in systemic lupus erythematosus patients at apparent low risk for cardiovascular disease.

Objective: This study aimed to determine whether sCD163, a soluble macrophage marker up-regulated in numerous inflammatory disorders, is predictive of accelerated atherosclerosis associated with systemic lupus erythematosus (SLE).Methods: Carotid ultrasound was prospectively performed, at baseline and during follow-up, in 63 consecutive SLE patients asymptomatic for cardiovascular disease (CVD) and 18 volunteer health workers. Serum sCD163 level was determined at baseline using enzyme-linked immunosorbent assay. The primary outcome was the presence of a carotid plaque. Factors associated with carotid plaques were identified through multivariate analysis.Results: Despite a low risk for cardiovascular events according to Framingham score in both groups (2.1 ± 3.8% in SLE vs 2.1 ± 2.9% in controls; p = 0.416), ultrasound at baseline showed a carotid plaque in 23 SLE patients (36.5%) and two controls (11.1%) (p = 0.039). Multivariate analysis showed that SLE status increased the risk for carotid plaque by a factor of 9 (p = 0.017). In SLE patients, sCD163 level was high (483.7 ± 260.8 ng/mL vs 282.1 ± 97.5 ng/mL in controls; p < 0.001) and independently associated with carotid plaques, as assessed by stratification based on sCD163 quartile values (p = 0.009), receiver operating characteristics (p = 0.001), and multivariate analysis (p = 0.015). sCD163 at baseline was associated with the onset of carotid plaque during follow-up (3 ± 1.4 years) in SLE patients who had no carotid plaque at the first evaluation (p = 0.041).Conclusion: sCD163 is associated with progressing carotid plaque in SLE and may be a useful biomarker for accelerated atherosclerosis in SLE patients at apparent low risk for CVD.

Concomitant association of giant cell arteritis and malignancy: a multicenter retrospective case-control study.

INTRODUCTION: Some studies suggest that there is an increased risk of malignancies in giant cell arteritis (GCA). We aimed to describe the clinical characteristics and outcomes of GCA patients with concomitant malignancy and compare them to a GCA control group. METHOD: Patients with a diagnosis of GCA and malignancy and with a maximal delay of 12 months between both diagnoses were retrospectively included in this study and compared to a control group of age-matched (3:1) patients from a multicenter cohort of GCA patients. RESULTS: Forty-nine observations were collected (median age 76 years). Malignancies comprised 33 (67%) solid neoplasms and 16 (33%) clonal hematologic disorders. No over-representation of a particular type of malignancy was observed. Diagnosis of GCA and malignancy was synchronous in 7 (14%) patients, while malignancy succeeded GCA in 29 (59%) patients. Malignancy was fortuitously diagnosed based on abnormalities observed in laboratory tests in 26 patients, based on imaging in 14 patients, and based on symptoms or clinical examination in the nine remaining patients. Two patients had a concomitant relapse of both conditions. When compared to the control group, patients with concomitant GCA and malignancy were more frequently male (p < 0.001), with an altered general state (p < 0.001), and polymyalgia rheumatica (p < 0.01). CONCLUSIONS: This study does not indicate an over-representation of any particular type of malignancy in GCA patients. Initial follow-up dictated by vasculitis may have led to an early identification of malignancy. Nevertheless, GCA male patients with an altered general state and polymyalgia rheumatica might more frequently show concomitant malignancies.

[Prevention of infections in adults and adolescents with systemic lupus erythematosus: Guidelines for the clinical practice based on the literature and expert opinion]. / Prévention des infections au cours du lupus systémique chez l'adulte et l'adolescent : élaboration de recommandations pour la pratique clinique, à partir d'une analyse de la littérature et de l'avis d'experts.

PURPOSE: To develop French recommendations about the management of vaccinations, the screening of cervical cancer and the prevention of pneumocystis pneumonia in systemic lupus erythematosus (SLE). METHODS: Thirty-seven experts qualified in internal medicine, rheumatology, dermatology, nephrology and pediatrics have selected recommendations from a list of proposition based on available data from the literature. For each recommendation, the level of evidence and the level of agreement among the experts were specified. RESULTS: Inactivated vaccines do not cause significant harm in SLE patients. Experts recommend that lupus patient should receive vaccinations accordingly to the recommendations and the schedules for the general public. Pneumococcal vaccination is recommended for all SLE patients. Influenza vaccination is recommended for immunosuppressed SLE patients. Live attenuated vaccines should be avoided in immunosuppressed patients. Yet, recent works suggest that they can be considered in mildly immunosuppressed patients. Experts have recommended a cervical cytology every year for immunosuppressed patients. No consensus was obtained for the prevention of pneumocystis pneumonia. CONCLUSION: These recommendations can be expected to improve clinical practice uniformity and, in the longer term, to optimize the management of SLE patients.

Quality of life in systemic lupus erythematosus: description in a cohort of French patients and association with blood hydroxychloroquine levels.

OBJECTIVES: Benefits of hydroxychloroquine (HCQ) use on physician reported outcomes are well documented in systemic lupus erythematosus (SLE). We assess for the first time the association and predictive value of blood HCQ levels towards health-related quality of life (HRQOL) in SLE. METHODS: Data from the PLUS study (a randomized, double-blind, placebo-controlled, multicentre study) were utilized. Blood HCQ levels were quantified by high-performance liquid chromatography along with HRQOL assessments (Medical Outcomes Study-SF-36) at baseline (V1) and month 7 (V2). RESULTS: 166 SLE patients' data were analysed. Mean (SD) age and disease duration were 44.4 (10.7) and 9.3 (6.8) years. Eighty-seven per cent were women. Mean (SD, median, IQR) HCQ concentrations in the blood at V1 were 660 (314, 615, 424) ng/ml and increased to 1020 (632, 906, 781) ng/ml at V2 (mean difference 366 units, 95% confidence interval -472 to -260, p < 0.001). No significant correlations between HCQ concentrations with HRQOL domains at V1 or V2 were noted. There were no differences in HRQOL stratified by HCQ concentrations. HCQ concentrations at V1 or changes in HCQ concentration (V2-V1) were not predictive of HRQOL at V2 or changes in HRQOL (V2-V1). CONCLUSIONS: No association of HCQ concentrations with current or longitudinal HRQOL were found in SLE.

Determinants of hydroxychloroquine blood concentration variations in systemic lupus erythematosus.

OBJECTIVE: Blood concentrations of hydroxychloroquine (HCQ) vary widely among patients with systemic lupus erythematosus (SLE). A pharmacokinetic/pharmacodynamic relationship has been found in different situations, and a very low blood concentration of HCQ is a simple marker of nonadherence to treatment. Therefore, interest in blood HCQ concentration measurement has increased, but little is known about factors that influence blood HCQ concentration variability. This study was undertaken to analyze determinants of blood HCQ concentrations. METHODS: We conducted a retrospective analysis of patient data, including data from the Plaquenil Lupus Systemic (PLUS) study, to determine the association of epidemiologic, clinical, and biologic factors with blood HCQ concentrations. Data for nonadherent patients (blood HCQ concentration <200 ng/ml) were excluded. RESULTS: To examine homogeneous pharmacologic data, we restricted the analyses of the PLUS data to the 509 SLE patients receiving 400 mg/day. We found no association of ethnicity or smoking with blood HCQ concentrations and no pharmacokinetic drug-drug interaction with antacids or with inhibitors or inducers of cytochrome P450 enzymes. On multivariate analysis, high body mass index (P = 0.008), no treatment with corticosteroids (P = 0.04), increased time between the last tablet intake and measurement of blood HCQ concentrations (P = 0.017), low platelet count (P < 0.001), low neutrophil count (P < 0.001), and high estimated creatinine clearance (P < 0.001) were associated with low blood HCQ concentrations. In 22 SLE patients with chronic renal insufficiency (median serum creatinine clearance 52 ml/minute [range 23-58 ml/minute]) who received 400 mg/day HCQ, the median blood HCQ concentration was significantly higher than that in the 509 patients from the PLUS study (1,338 ng/ml [range 504-2,229 ng/ml] versus 917 ng/ml [range 208-3316 ng/ml]) (P < 0.001). CONCLUSION: We provide a comprehensive analysis of determinants of blood HCQ concentrations. Because this measurement is increasingly being used, these data might be useful for clinicians.

[Screening and management of cardiovascular risk factors in systemic lupus erythematosus: Recommendations for clinical practice based on the literature and expert opinion]. / Dépistage et prise en charge du risque cardiovasculaire au cours du lupus systémique : élaboration de recommandations pour la pratique clinique, à partir d'une analyse de la littérature et de l'avis d'experts.

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.

Pituitary-adrenal function after prolonged glucocorticoid therapy for systemic inflammatory disorders: an observational study.

CONTEXT: Glucocorticoid therapy is being used in a wide variety of systemic disorders. Reference papers, published more than 20 years ago, showed no correlation between adrenal insufficiency risk and dose or duration of glucocorticoid therapy. OBJECTIVE: Our objective was to evaluate the extent to which long-term glucocorticoid therapy damages the pituitary-adrenal axis in patients with systemic inflammatory disorders. DESIGN: We conducted a retrospective observational study from January 2011 to August 2012. SETTING: This was a monocentric study at the Department of Internal Medicine, Bichat Hospital, Paris-Diderot University, Paris, France. PARTICIPANTS: Sixty consecutive patients who were receiving long-term prednisone therapy for systemic inflammatory disorders and in whom discontinuation of glucocorticoid treatment was planned. INTERVENTION: A short Synacthen test was performed. A bolus of 0.25 mg 1-24-ACTH was injected in the morning, 24 hours after the most recent dose of prednisone. Cortisol was measured at baseline and 60 minutes after Synacthen injection. MAIN OUTCOME MEASURES: We assessed frequency and risk estimate of pituitary-adrenal dysfunction. RESULTS: Twenty-nine patients (48.3%) had adrenal insufficiency defined by a plasmatic cortisol <100 nmol/L (n = 13) at baseline (time 0) or <550 nmol/L (n = 16) 60 minutes after Synacthen injection. Cumulative dose (area under the receiver operating characteristic curve = 0.77 [95% confidence interval = 0.62-0.91], P = .007) and exposure (area under the receiver operating characteristic curve 0.80 [95% confidence interval = 0.67-0.93], P = .002) to prednisone were predictive for adrenal insufficiency based on a T0 <100 nmol/L. Prednisone was stopped in 29 of 31 patients (93.5%) showing a normal response to short Synacthen test; none of these patients required hydrocortisone replacement with a mean follow-up of 10 (± 6) months. CONCLUSION: Adrenal insufficiency is frequent in patients treated with long-term glucocorticoids for systemic inflammatory disorders and is related to duration and cumulative dose of steroids.

[Long-term follow-up of a French cohort of retroperitoneal fibrosis]. / Fibrose(s) rétropéritonéale(s) : stratégie diagnostique, pathologies associées et suivi à long terme d'une cohorte française.

PURPOSE: Retroperitoneal fibrosis (RPF) is a rare disease with an expanding etiologic spectrum. We aimed to analyze non-invasive diagnosis strategy, associated disorders, monitoring, treatment and prognosis. METHODS: Retrospective cohort study in a single tertiary center. RESULTS: Eighteen RPF cases (11 males) followed between 1996 and 2009 were reviewed. Blood CRP level was high in all cases before treatment. CT scan, associated or not with MRI or 18-FDG PET-scan, confirmed the diagnosis in 15 patients. Histological analysis of a surgical biopsy specimen was performed in only three cases. Ten patients suffered retroperitoneal fibrosis secondary to systemic vasculitis (granulomatosis with polyangeitis, n=1, Takayasu aortitis, n=2), systemic fibrosis with Riedel thyroiditis (n=1) and atheromatous periaortitis (n=6). Fifteen patients were treated with corticosteroids with a mean treatment duration of 60 months (12-228). Dependency to corticosteroids was recorded in ten patients. Patients with fibrosis related to vasculitis were younger, had a higher CRP level, more frequent corticosteroid dependency and a higher relapse rate. Relapses were successfully treated with steroids. Immunosuppressive treatment was only prescribed in the setting of systemic vasculitis. No patient died, after a 6±2 years follow-up. Late relapses could occur, sometimes years after steroid therapy cessation. CONCLUSION: In our study, RPF occurred as a secondary disorder in 60% of the cases. Disease extension, relapse rate and treatment response varied according to the underlying cause of RPF, pleading for an extensive and systematic initial assessment. Since no death or end-stage renal insufficiency was observed, RPF might be considered as a steroid-sensitive and benign disorder.

[Susac syndrome]. / Syndrome de Susac.

Susac syndrome is a mysterious vasculopathy affecting brain, retina and inner ear in young women. Main features of the disease are increasingly recognized: subacute encephalopathy often mimicking psychosis and frequently heralded with unusual ophthalmic migraine; frequent subclinical meningitis; brain MRI with multiple and bilateral white and gray matter nuclei lesions, with prominent involvement of corpus callosum; bilateral involvement of central retina artery branches, not only with occlusions but also with peculiar leakage of fluorescein through arteriolar walls on late stages of angiography; non-specific bilateral cochleovestibular symptoms with audiogram showing perception hypoacousia that predominates on low frequencies. Outcome, prognosis, pathogenesis and a rational basis for treatment are discussed in this review. A key message for the clinician should be to perform brain MRI, audiogram and retinal angiography whatever the mode of entry, in order not to miss one (or two) features of this syndrome triad.

Lambert-Eaton myasthenic syndrome and follicular thymic hyperplasia in systemic lupus erythematosus.

Fatigue is a prominent feature of systemic lupus erythematosus (SLE), usually ascribed to various factors, such as muscle or joint involvement, anaemia or depression. The Lambert-Eaton myasthenic syndrome (LEMS) is a rare autoantibody-mediated disorder of neuro-muscular transmission. We report on a well-defined LEMS associated with thymus hyperplasia in a SLE patient. An African 41 years-old SLE patient presented with persisting fatigue, myalgia and dyspnea, abolished reflexes and a bilateral ptosis. Neuromuscular electrodiagnostic study showed a clear-cut potentiation that was typical of a pre-synaptic neuromuscular junction disease. Anti-calcium gated channels antibodies were disclosed in serum and a diagnosis of LEMS was made. A total body CT-scan revealed an antero-superior mediastinal mass, compatible with thymoma. The tumour was surgically removed with a final diagnosis of follicular thymic hyperplasia. In conclusion, our observation provides a new example of entangled organ-specific and systemic autoimmunity in the context of thymus pathology. Potentiation study during electromyography should be performed systematically to rule out LEMS in patients with SLE and muscle weakness.

Bone and joint involvement in Fabry disease.

Fabry disease (FD) is an X-linked lysosomal storage disease caused by deficient activity of the enzyme alpha-galactosidase A. Although the disease has progressive effects on most organ systems in the body, data is limited regarding skeletal involvement in this rare disorder. We describe four family-related patients, three men and one premenopausal female, sharing a classic phenotype of FD. Dual-energy X-ray was performed in all cases and osteoporosis or osteopenia were found in all patients and osteoporotic fractures in one. One patient also showed both neuropathic joint disease and osteonecrosis. Several mechanisms that may explain osteoporosis and osteoarthropathy in the setting of FD are emphasized.

Lytic bone lesions in lupus-associated myelofibrosis.

Myelofibrosis is associated with numerous causes other than hematologic malignant neoplasms, including autoimmune diseases. We describe a 44-year-old woman who suffered bone lytic lesions with extramedullary haematopoiesis in the setting of myelofibrosis associated with systemic lupus erythematosus.

Aseptic meningitis and ischaemic stroke in Fabry disease.

BACKGROUND: Fabry disease (OMIM 301 500) is an X-linked lysosomal storage disease. Neurological symptoms in Fabry disease mainly include stroke, acroparesthesia, cranial nerve palsies and autonomic dysfunction. We report on aseptic meningitis in Fabry patients. METHODS: Clinical analysis, brain magnetic resonance imaging, cerebrospinal fluid analysis, treatment and outcome data were analysed in three cases of meningitis associated with Fabry disease. FINDINGS: Mean age at meningitis onset was 26.6 (24-28) years. Headache was present in all cases and fever in two cases. Meningitis was always diagnosed before Fabry disease. A familial history of Fabry disease was present in two cases. Non-neurological symptoms caused by Fabry disease were present in all cases. All patients also suffered stroke and sensorineural hearing loss. Cerebrospinal fluid (CSF) analysis showed pleocytosis (mean, 36; range: 8-76 cells/mm(3)) and a high protein level (mean, 63; range, 47-70 mg/dl). C-reactive protein blood levels and erythrocyte sedimentation rate were raised. Diagnosis was assessed by low alpha-galactosidase A dosage and/or gene mutation analysis in all cases. All patients were treated with enzyme replacement therapy (ERT). In two cases, lumbar puncture was repeatedly performed and there was no normalisation of CSF under ERT alone, at 9 and 24 months of follow-up, respectively. One patient who suffered intracranial hypertension was treated efficiently with steroids, associated with azathioprine. The fact that Fabry disease could be an auto-inflammatory disorder is discussed. INTERPRETATION: Fabry disease may cause aseptic meningitis.
