[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.

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.

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.

[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.

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.
