Efficacy of anti-TNF alpha in severe and/or refractory Behçet's disease: Multicenter study of 124 patients.

OBJECTIVE: To report the efficacy and safety of anti-TNF agents in patients with severe and/or refractory manifestations of Behçet's disease (BD). METHODS: We performed a multicenter study of main characteristics and outcomes of anti-TNF alpha treatments [mainly infliximab (62%), and adalimumab (30%)] in 124 BD patients [48% of men; median age of 33.5 (28-40) years]. RESULTS: Overall response (i.e. complete and partial) rate was 90.4%. Clinical responses were observed in 96.3%, 88%, 70%, 77.8%, 92.3% and 66.7% of patients with severe and/or refractory ocular, mucocutaneous, joint, gastro-intestinal manifestations, central nervous system manifestations and cardiovascular manifestations, respectively. No significant difference was found with respect to the efficacy of anti-TNF used as monotherapy or in association with an immunosuppressive agent. The incidence of BD flares/patient/year was significantly lower during anti-TNF treatment (0.2 ± 0.5 vs 1.7 ± 2.4 before the use of anti-TNF, p < 0.0001). The prednisone dose was significantly reduced at 6 and 12 months (p < 0.0001). In multivariate analysis, retinal vasculitis was negatively associated with complete response to anti-TNF (OR = 0.33 [0.12-0.89]; p = 0.03). The efficacy and relapse free survival were similar regardless of the type of anti-TNF agent used. After a median follow-up of 21 [7-36] months, side effects were reported in 28% of patients, including infections (16.3%) and hypersensitivity reactions (4.1%). Serious adverse events were reported in 13% of cases. CONCLUSION: Anti-TNF alpha therapy is efficient in all severe and refractory BD manifestations. Efficacy appears to be similar regardless of the anti-TNF agent used (infliximab or adalimumab).

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.

Intermediate uveitis, an ophthalmological manifestation of systemic disease.

PURPOSE: Intermediate uveitis is frequently indicative associated with systemic disease. In addition to the initial evaluation of the patient with intermediate uveitis, we sought to determine the role of longitudinal follow-up in improving the diagnosis of systemic disease associated with intermediate uveitis. METHOD: Retrospective analysis of a cohort of 51 patients with intermediate uveitis followed for 5 to 13 years. RESULTS: Upon initial evaluation, an underlying disease associated with the intermediate uveitis was found in nine out of the 51 patients. Among the remaining patients, after at least 5 years of follow-up, eight new associated diagnoses were revealed (primarily inflammatory diseases and cancers). CONCLUSION: These results suggest that the initial work-up of the patient with intermediate uveitis is not sufficiently sensitive and that careful follow-up of these patients considerably improves the diagnosis of associated disease.

[Immunological aspects of the antiphospholipid syndrome]. / Aspects immunologiques du syndrome des antiphospholipides.

Antiphospholipid antibodies constitute a group of heterogeneous antibodies, which mainly recognize complexes made of proteins and anionic phospholipids. The nature of these complexes is currently better defined, as well as known, the structure of the antiphospholipid antibodies owing to the analysis of the monoclonal forms of these antibodies which were also studied both in terms of their precise specificities and cross-reactivity. However, the origin of these autoantibodies is not clearly understood, as well as the possible link between antiphospholipid antibodies present in healthy individuals, and those observed in autoimmune diseases. Only a fraction of antiphospholipid antibodies are pathogenic and directly responsible for the clinical manifestations of the antiphospholipid syndrome, but there is, to date, no biological test able to accurately detect pathogenic antiphospholipid antibodies. The diverse mechanisms which link these autoantibodies to the occurrence of symptoms, mainly during obstetrical complications, are better understood, and suggest new therapeutic avenues.

[Behçet's disease in obstetrics and gynecology]. / Maladie de Behçet en gynécologie-obstétrique.

Behçet's disease is a multisystemic disease of unknown origin characterized by a recurrent bipolar aphtosis (oral and genital) associated with vascular, digestive or articular symptoms. Gynecologists can be faced to this disease at any time of the life of their patients, including during the pregnancy. Given that the first demonstrations of the disease can be genital, they are in the front line to evoke this diagnosis. They thus have to know the main characteristics of the disease to make the diagnosis and to organize a multidisciplinary management. During pregnancy, the treatment of the disease is to be adapted to avoid teratogenic drugs, and adapt the doses of the treatment.

Value of (18)F-FDG-PET/CT in patients with fever of unknown origin and unexplained prolonged inflammatory syndrome: a single centre analysis experience.

OBJECTIVE: The aim of our study was to evaluate the diagnostic contribution of (18)F-fluoro-deoxyglucose ((18)F-FDG)-positron emission tomography (PET)/computed tomography (CT) in patients with fever of unknown origin (FUO) or unexplained prolonged inflammatory syndrome (UPIS) in real life. PATIENTS AND METHODS: We performed a retrospective study including 14 patients with FUO or UPIS hospitalised in our institution (Strasbourg University Hospital, France) between January 2005 and July 2006. (18)F-FDG-PET/CT was considered helpful when abnormal results allowed an accurate diagnosis. RESULTS: (18)F-FDG-PET/CT was helpful in half the patients (7/14) for final diagnosis. A diagnosis was reached in 87.5% of the patients (7/8) with an abnormal (18)F-FDG-PET/CT but only in 50% of the patients (3/6) with a normal (18)F-FDG-PET/CT. Conventional chest and abdominal CT was performed in 13 patients before ordering (18)F-FDG-PET/CT. We considered that (18)F-FDG-PET/CT was essential to establish the final diagnosis in only 23% of the patients (3/13) since neither chest nor abdominal CT identified abnormalities consistent with the final diagnosis. However, among the three patients, two were diagnosed with large vessel vasculitis and one patient with local prosthetic infection. CONCLUSIONS: Our study supports the potential interest of (18)F-FDG-PET/CT in the diagnostic workup of FUO and UPIS as it helped establish a fine diagnosis in half of the cases. However, (18)F-FDG-PET/CT appeared to be essential to the final diagnosis in only 23% of the cases. In our opinion, this protocol should be performed as a second level test, especially when conventional CT is normal or is unable to discriminate between active and silent lesions.

Videocapsule endoscopy is useful for the diagnosis of intestinal lymphangiectasia.

We study two authentic cases of protein-losing enteropathy, the diagnosis of which was facilitated using Given M2A videocapsule endoscopy. The first case corresponded to a primary intestinal lymphangiectasia confirmed by jejunum biopsies and the second one to a protein-losing enteropathy with lymphatic abnormalities secondary to a chronic constrictive pericarditis. In the first case, the mucosa of jejunum presented with a diffuse oedematous aspect, whitish villi, white curved lines probably related to submucosal dilated lymphatics and lacteal juice. In the second case, capsule endoscopy showed oedematous aspect of jejunum mucosa associated with white curved lines similar to those observed in the first case. Videocapsule endoscopy is useful in cases of protein-losing enteropathy to identify presence of intestinal lymphangiectasia and to specify their localisation after ruling out other disorders liable to induce protein-losing gastrointestinal syndrome.

[Coagulation disorders and arterial thromboembolic events in non-small-cell lung cancer. A case report]. / Anomalies de la coagulation et événements thromboemboliques artériels dans le cancer bronchique non à petites cellules. A propos d'une observation.

Certain coagulation disorders can occur in patients with cancer and thromboembolic complications are frequent. We report the case of a 53-Year-old patient with metastatic adenocarcinoma of the lung treated with chemotherapy who presented several cerebral arterial thromboembolic events leading to death a few weeks after the initial diagnosis of cancer. This case illustrates the important role of certain satellite disorders related to coagulation activation: non-bacterial thrombotic endocarditis, disseminated intravascular coagulation, anti-phospholipid antibody syndrome. The role of anticancer chemotherapy as a favoring factor for thromboembolic events is also emphasized in patients with non-small-cell lung cancer.
