RESUMO

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.

RESUMO

OBJECTIVE: To describe the outcome and tolerance in patients treated with anti-TNFα in severe and refractory major vessel disease in Behçet's disease (BD). METHODS: A multicenter study evaluating 18 refractory BD patients with major vessel involvement [pulmonary artery (n = 4), aorta (n = 4) or peripheral artery aneurysm (n = 1) and/or pulmonary artery (n = 7), inferior vena cava (n = 5), or intra-cardiac (n = 3) thrombosis or Budd Chiari Syndrome (n = 2)] treated with anti-TNFα agents. RESULTS: Vascular remission was achieved in 16 (89%) patients. The 9 months risk of relapse was significantly higher with conventional immunosuppressants used prior anti-TNFα agents as compared to anti-TNFα therapy [OR = 8.7 (1.42-62.6), p = 0.03]. The median daily dose of corticosteroids significantly decreased at 12 months. Side effects included infection (n = 4) and pulmonary edema (n = 1). CONCLUSION: TNFα-antagonists are safe and might be associated with a decreased risk of relapse at 9 months compared to conventional immunosuppressants in BD patients with major vessels disease.

RESUMO

BACKGROUND: Mammalian target of rapamycin complex 1 (mTORC 1) drives the proinflammatory expansion of T helper (TH) type 1, TH17 cells and controls fibroblast proliferation, typical features of large vessel vasculitis (LVV) pathogenesis. Molecular pathways involved in arterial lesions of LVV are unknown. METHODS: We evaluate mTORC pathway activation in vascular aorta lesions and in T cell homeostasis of patients with LVV. RESULTS: Proliferation of both endothelial cells and vascular smooth-muscle cells was shown in vascular lesions in LVV. The vascular endothelium of proliferating aorta vessels from patients with LVV showed indications of activation of the mTORC1 pathway (S6RP phosphorylation). In cultured vascular endothelial cells, sera from patients with LVV stimulated mTORC1 through the phosphorylation of S6RP. mTORC1 activation was found also in Th1 and Th17 cells both systemically and in inflamed vessels. Patients with LVV exhibited a diminished S6RP phosphorylation in Tregs. Inhibition of mTORC1 pathway with rapamycin, increase Tregs and decrease effector CD4+IFNγ+, CD4+IL17+ and CD4+IL21+ T cells in patients with LVV. CONCLUSIONS: We provided evidence that mTORC1 pathway has a central role in driving T cell inflammation and vascular lesions in LVV. Targeting mTORC pathway may represent a new therapeutic option in patients with LVV.

RESUMO

Hepatitis C virus (HCV) infection is a systemic disease associated with both hepatic and extrahepatic manifestations. The burden associated with the hepatic manifestation of HCV infection has been well documented in Europe, although that of HCV extrahepatic manifestations remains unknown. In this study, we estimated the annual direct medical costs associated with HCV extrahepatic manifestations in five European countries. A previously validated economic model was used to estimate the annual direct medical cost associated with HCV extrahepatic manifestations. Global excess prevalence of extrahepatic manifestations in HCV patients relative to that in non-HCV patients was obtained from a recent meta-analysis. Per-patient per-year inpatient, outpatient and medication costs to treat each extrahepatic manifestation were from the literature, national databases or expert opinion if unavailable otherwise. All costs were adjusted to 2016 euros (€). The overall direct medical costs associated with HCV extrahepatic manifestations were calculated by multiplying the total per-patient per-year costs of each by the respective excess prevalence rates and then by the size of the HCV-infected population in each country. Treatment impact with direct-acting antivirals (DAAs) was explored using HCV extrahepatic manifestations excess prevalence rates among cured patients compared to untreated HCV patients, as sourced from a meta-analysis. The total annual direct medical cost associated with HCV extrahepatic manifestations was estimated to be 2.17 billion euro (€), with a per-HCV-patient cost ranging from €899 to €1647 annually. DAA treatment was projected to result in cost savings of €316 million per year. We find that the annual economic burden of extrahepatic manifestations is significant and may be partly mitigated by treatment with DAAs.

RESUMO

Objective To study the outcome of patients with antiphospholipid syndrome (APS) after oral anticoagulant treatment cessation. Methods We performed a retrospective study of patients with APS experiencing cessation of oral anticoagulant and enrolled in a French multicentre observational cohort between January 2014 and January 2016. The main outcome was the occurrence of recurrent thrombotic event after oral anticoagulation cessation. Results Forty four APS patients interrupted oral anticoagulation. The median age was 43 (27-56) years. The median duration of anticoagulation was 21 (9-118) months. Main causes of oral anticoagulant treatment cessation were switch from vitamin K antagonists to aspirin in 15 patients, prolonged disappearance of antiphospholipid antibodies in ten, bleeding complications in nine and a poor therapeutic adherence in six. Eleven (25%) patients developed a recurrent thrombotic event after oral anticoagulation cessation, including three catastrophic APS and one death due to lower limb ischemia. Antihypertensive treatment required at time of oral anticoagulants cessation seems to be an important factor associated with recurrent thrombosis after oral anticoagulant cessation (15.2% in patients with no relapse versus 45.5% in patients with recurrent thrombosis, p = 0.038). Oral anticoagulant treatment was re-started in 18 (40.9%) patients. Conclusion The risk of a new thrombotic event in APS patients who stopped their anticoagulation is high, even in those who showed a long lasting disappearance of antiphospholipid antibodies. Except for the presence of treated hypertension, this study did not find a particular clinical or biological phenotype for APS patients who relapsed after anticoagulation cessation. Any stopping of anticoagulant in such patients should be done with caution.

RESUMO

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.

RESUMO

OBJECTIVES: The aim of this study was to describe the proportion of liver-related diseases (LRDs) as a cause of death in HIV-infected patients in France and to compare the results with data from our five previous surveys. METHODS: In 2010, 24 clinical wards prospectively recorded all deaths occurring in around 26 000 HIV-infected patients who were regularly followed up. Results were compared with those of previous cross-sectional surveys conducted since 1995 using the same design. RESULTS: Among 230 reported deaths, 46 (20%) were related to AIDS and 30 (13%) to chronic liver diseases. Eighty per cent of patients who died from LRDs had chronic hepatitis C, 16.7% of them being coinfected with hepatitis B virus (HBV). Among patients who died from an LRD, excessive alcohol consumption was reported in 41%. At death, 80% of patients had undetectable HIV viral load and the median CD4 cell count was 349 cells/µL. The proportion of deaths and the mortality rate attributable to LRDs significantly increased between 1995 and 2005 from 1.5% to 16.7% and from 1.2‰ to 2.0‰, respectively, whereas they tended to decrease in 2010 to 13% and 1.1‰, respectively. Among liver-related causes of death, the proportion represented by hepatocellular carcinoma (HCC) dramatically increased from 5% in 1995 to 40% in 2010 (p = 0.019). CONCLUSIONS: The proportion of LRDs among causes of death in HIV-infected patients seems recently to have reached a plateau after a rapid increase during the decade 1995-2005. LRDs remain a leading cause of death in this population, mainly as a result of hepatitis C virus (HCV) coinfection, HCC representing almost half of liver-related causes of death.

RESUMO

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).

RESUMO

Patients with chronic hepatitis C virus (HCV) infection frequently present with extrahepatic manifestations covering a large spectrum, involving different organ systems leading to the concept of systemic HCV infection. These manifestations include autoimmune phenomena and frank autoimmune and/or rheumatic diseases and may dominate the course of chronic HCV infection. Chronic HCV infection causes liver inflammation affecting the development of hepatic diseases. HCV is also a lymphotropic virus that triggers B cells and promotes favorable conditions for B lymphocyte proliferation, including mixed cryoglobulinemia (MC) and MC vasculitis, which is the most prominent extrahepatic manifestation of chronic HCV infection. HCV may also promote a low-grade chronic systemic inflammation that may affect the development of some extrahepatic manifestations, particularly cardiovascular and cerebral vascular diseases. Recognition of extrahepatic symptoms of HCV infection could facilitate early diagnosis and treatment. The development of direct-acting antiviral agents (DDAs) has revolutionized HCV treatment. DDAs, as well as new B-cell-depleting or B-cell-modulating monoclonal antibodies, will expand the panorama of treatment options for HCV-related extrahepatic manifestations including cryoglobulinemic vasculitis. In this context, a proactive, integrated approach to HCV therapy should maximize the benefits of HCV therapy, even when liver disease is mild.

RESUMO

BACKGROUND: Transverse myelitis is a rare complication of systemic lupus erythematosus (SLE). This retrospective multicentre study identifies the prognostic factors in a relatively large patient series. PATIENTS AND METHODS: Twenty patients fulfilled the SLE criteria of the ACR classification and the Transverse Myelitis Consortium Working Group. A severe neurological flare was defined as muscle strength grade <3/5 in more than half the muscle groups at the motor neurological level. Inability to run or another significant ambulation-unrelated disability was considered as 'unfavourable neurological outcome'. RESULTS: Myelitis was the first SLE symptom in 12 patients; in the eight others, it occurred 8.6 years (median delay) after SLE onset. Eleven patients presented severe neurological impairments. The treatment included corticosteroids in all patients associated with intravenous cyclophosphamide in 11 and/or hydroxychloroquine in 14. Unfavourable outcomes were observed in 53% of the patients at six months and in 28% at end of follow-up (median: 5.9 years). An initial severe neurological impairment and no cyclophosphamide use were associated with unfavourable neurological outcomes at six months and at end of follow-up, respectively. CONCLUSION: Transverse myelitis may reveal SLE or occur more than 10 years after SLE diagnosis. The initial severity of the neurological flare (with paraplegia) is the main prognostic marker. The study provides arguments for cyclophosphamide use.

RESUMO

The host genetic basis of mixed cryoglobulin vasculitis is not well understood and has not been studied in large cohorts. A genome-wide association study was conducted among 356 hepatitis C virus (HCV) RNA-positive individuals with cryoglobulin-related vasculitis and 447 ethnically matched, HCV RNA-positive controls. All cases had both serum cryoglobulins and a vasculitis syndrome. A total of 899 641 markers from the Illumina HumanOmni1-Quad chip were analyzed using logistic regression adjusted for sex, as well as genetically determined ancestry. Replication of select single-nucleotide polymorphisms (SNPs) was conducted using 91 cases and 180 controls, adjusting for sex and country of origin. The most significant associations were identified on chromosome 6 near the NOTCH4 and MHC class II genes. A genome-wide significant association was detected on chromosome 6 at SNP rs9461776 (odds ratio=2.16, P=1.16E-07) between HLA-DRB1 and DQA1: this association was further replicated in additional independent samples (meta-analysis P=7.1 × 10(-9)). A genome-wide significant association with cryoglobulin-related vasculitis was identified with SNPs near NOTCH4 and MHC Class II genes. The two regions are correlated and it is difficult to disentangle which gene is responsible for the association with mixed cryoglobulinemia vasculitis in this extended major histocompatibility complex region.

RESUMO

UNLABELLED: This consensus article reviews the diagnosis and treatment of osteoporosis in geriatric populations. Specifically, it reviews the risk assessment and intervention thresholds, the impact of nutritional deficiencies, fall prevention strategies, pharmacological treatments and their safety considerations, the risks of sub-optimal treatment adherence and strategies for its improvement. INTRODUCTION: This consensus article reviews the therapeutic strategies and management options for the treatment of osteoporosis of the oldest old. This vulnerable segment (persons over 80 years of age) stands to gain substantially from effective anti-osteoporosis treatment, but the under-prescription of these treatments is frequent. METHODS: This report is the result of an ESCEO (European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis) expert working group, which explores some of the reasons for this and presents the arguments to counter these beliefs. The risk assessment of older individuals is briefly reviewed along with the differences between some intervention guidelines. The current evidence on the impact of nutritional deficiencies (i.e. calcium, protein and vitamin D) is presented, as are strategies to prevent falls. One possible reason for the under-prescription of pharmacological treatments for osteoporosis in the oldest old is the perception that anti-fracture efficacy requires long-term treatment. However, a review of the data shows convincing anti-fracture efficacy already by 12 months. RESULTS: The safety profiles of these pharmacological agents are generally satisfactory in this patient segment provided a few precautions are followed. CONCLUSION: These patients should be considered for particular consultation/follow-up procedures in the effort to convince on the benefits of treatment and to allay fears of adverse drug reactions, since poor adherence is a major problem for the success of a strategy for osteoporosis and limits cost-effectiveness.

RESUMO

Although preliminary studies showed that preexposure prophylaxis (PrEP) lowers the HIV transmission in individuals with HIV, confirmative trials are ongoing and PrEP is not routinely recommended. The aim of this study was to assess whether individuals with HIV share antiretroviral (ARV) drugs for PrEP and to describe awareness and discussion on PrEP in this population. A cross-sectional survey was conducted in France in 23 representative departments of infectious diseases and internal medicine. Physicians administered an anonymous standardized questionnaire to all individuals with HIV receiving ARVs and followed between 24 and 31 October 2011. The questionnaire included items regarding PrEP (awareness; discussion with their close circle, physician or patients' association; experience), personal sociodemographic characteristics, risk behaviors and HIV status of the participants. Five hundred and ninety three participants were recruited: male 74.2% (men who have sex with men 52.4%, heterosexuals 21.6%), member of patient's association 9.8%. Half of them (50.6%) lived with a stable partner and 35.2% with an HIV-negative partner. Almost half (41.8%) were aware and 29.5% had had discussion about PrEP. In logistic regression, awareness and discussion on PrEP were more frequent: (1) among males, in patients' association members (p< 0.001 for both) and in nonheterosexuals (p=0.023 and 0.057, respectively); (2) among women, in those not living with a stable partner (p=0.035 and p=0.03, respectively) or living with an HIV-negative partner (p=0.049 and p=0.083, respectively). One percent of the participants declared having shared ARVs with someone and 8.3% reported PrEP in their close circle. Men reporting PrEP in their close circle shared ARVs more frequently than those who did not (10.3% vs. 0.2%, p < 0.001). Today, individuals with HIV do not seem to widely share personal ARVs for PrEP with seronegative people. A significant number of individuals with HIV are aware of and commonly discuss PrEP.

OBJECTIVE: Primary Sjögren's syndrome (SS) is an autoimmune disease associated with a high risk of developing non-Hodgkin's lymphoma. This study was undertaken to determine the nature of B cells driving lymphoproliferation in primary SS. METHODS: B cell subsets and function were analyzed in peripheral blood from 66 adult patients with primary SS (including 14 patients with B cell lymphoproliferative disease [LPD]) and 30 healthy donors, using flow cytometry, calcium mobilization, and gene array analysis. The reactivity of recombinant antibodies isolated from single B cells from patients with primary SS and LPD was tested using an enzyme-linked immunosorbent assay. RESULTS: We observed an expansion of an unusual CD21-/low B cell population that correlated with lymphoproliferation in patients with primary SS. A majority of CD21-/low B cells from patients with primary SS expressed autoreactive antibodies, which recognized nuclear and cytoplasmic structures. These B cells belonged to the memory compartment, since their Ig genes were mutated. They were unable to induce calcium flux, become activated, or proliferate in response to B cell receptor and/or CD40 triggering, suggesting that these autoreactive B cells may be anergic. However, CD21-/low B cells from patients with primary SS remained responsive to Toll-like receptor (TLR) stimulation. Molecules specifically expressed in CD21-/low B cells that are likely to induce their unresponsive stage were detected in gene array analyses. CONCLUSION: Patients with primary SS who display high frequencies of autoreactive and unresponsive CD21-/low B cells are susceptible to developing lymphoproliferation. These cells remain in peripheral blood controlled by functional anergy instead of being eliminated, and chronic antigenic stimulation through TLR stimulation may create a favorable environment for breaking tolerance and activating these cells.

RESUMO

Fibrillary glomerulonephritis (FGN) is a glomerular disease described since 1977, with a prevalence in renal biopsies of less than 1%. It presents as renal failure, proteinuria, haematuria and hypertension in middle-aged adults. It is defined histologically, using light microscopy, which reveals organised deposits of fibrils measuring around 20nm, which are negative for Congo red staining. Electron microscopy, the first gold standard for diagnosis, has now been superseded by immunohistochemistry using the anti-DNAJB9 antibody. The discovery of this molecule has revolutionised the diagnosis of GNF, thanks to its excellent sensitivity and specificity (98% and 99% respectively). The association of GNF with hepatitis C virus, autoimmune diseases, neoplasia or haemopathy is debated. Renal prognosis is guarded, with 50% of patients progressing to end-stage renal failure within 2 to 4years of diagnosis. In the absence of randomised controlled trials, the recommended treatment is based on nephroprotective measures, corticosteroid therapy and possibly a second-line immunosuppressant such as rituximab. After renal transplantation, recovery or recurrence is possible. The pathophysiology of the disease is still poorly understood, and further studies are needed.

RESUMO

UNLABELLED: We have reviewed 47 drug rash with eosinophilia and systemic symptoms (DRESS) cases associated to strontium ranelate reported up to March 2011 to the Marketing Holder. The main signs were skin rash, fever, face oedema hypereosinophilia and liver involvement. For ten patients, persistence of DRESS symptoms was reported at the latest news obtained, and DRESS was identified as the direct cause of death in one case. The maximum incidence of DRESS associated with strontium ranelate was 1/24,112 [95 % CI (1/14,859; 1/42,194)] newly treated patients in France. Because DRESS is a severe drug reaction, the occurrence of a rash in a patient treated with strontium ranelate should lead to prompt and permanent treatment discontinuation. INTRODUCTION: This study aims to describe cases of DRESS reported to the Marketing Authorisation Holder worldwide for patients receiving strontium ranelate by practitioner or by regulatory authorities. METHODS: Spontaneously reported hypersensitivity events from the strontium ranelate pharmacovigilance database since marketing authorisation (2004) to March 2011 were reviewed by an expert committee. Cases of DRESS were classified as established, probable, possible or no DRESS according to expert judgement. National incidences of DRESS were estimated in relation to the number of newly treated patients. RESULTS: Up to March 2011, 325 cases of strontium ranelate-induced hypersensitivity events were assessed from which 47 DRESS cases were confirmed. Mean age was 68.7 years and besides skin rash, the main signs and symptoms were hypereosinophilia, liver involvement, fever and face oedema. Median time to skin reaction was 33.5 days after treatment start. Most patients (62 %) recovered at the time of reporting or were recovering. For ten patients, persistence of DRESS symptoms was reported at the latest news obtained. Relapses were observed in a single case. The mortality rate was 8.5 %. The maximum incidence of DRESS associated with strontium ranelate was 1/24,112 [95 % CI (1/14,859; 1/42,194)] newly treated patients in France. CONCLUSION: DRESS is a well-identified and characterised adverse reaction to strontium ranelate. This risk should be integrated in the risk-benefit balance evaluation of patient treatment, and the occurrence of a rash should lead to prompt and permanent treatment discontinuation with careful follow-up.

RESUMO

OBJECTIVE: To investigate and describe the long-term outcome of venous thrombosis in patients with Behçet's disease (BD). METHODS: In a retrospective cohort of 807 BD patients, a reported 296 patients (36.7%) (73.3% male, median age 30 years [interquartile range 24-36 years]) met the international classification criteria for BD and had venous thrombosis. We assessed factors associated with thrombosis relapse and mortality. RESULTS: There were a total of 586 venous thrombosis events, including 560 cases of deep thrombosis and 26 cases of superficial thrombosis. Deep venous thrombosis events included 323 cases of limb thrombosis (55.1%), 77 cases of cerebral venous thrombosis (13.1%), 57 cases of pulmonary embolism (9.7%), 63 cases of vena cava lesions (10.7%), 14 cases of Budd-Chiari syndrome (2.4%), and 13 cases of cervical vein thrombosis (2.2%). One hundred of 296 patients (33.8%) experienced at least 1 venous thrombosis relapse. The mortality rate was 6.4% (19 of 296 patients) after a median followup of 4.75 years (interquartile range 2-7 years). In univariate analysis, death was associated with cardiac involvement (P = 0.026) and Budd-Chiari syndrome (P = 0.004). In multivariate analysis, the use of immunosuppressive agents was found to prevent relapse of venous thrombosis (hazard ratio 0.27 [95% confidence interval 0.14-0.52], P = 0.00021), and there was a trend toward prevention of relapse with the use of glucocorticoids (hazard ratio 0.62 [95% confidence interval 0.40-0.97], P = 0.058). CONCLUSION: Immunosuppressive agents significantly reduce venous thrombosis relapse in BD.

RESUMO

Neurosarcoidosis (NS) is a rare but severe form of sarcoidosis. NS is associated with significant morbidity and mortality. Mortality is about 10% at 10 years with more than 30% of patients who have a significant disability. The most frequent features are cranial neuropathy (the facial and optic nerve most commonly affected), cranial parenchymal lesions, meningitis, spinal corn abnormalities (20-30%) and more rarely peripheral neuropathy (approximately 10-15%). The challenge of diagnosis is to eliminate other diagnoses. Atypical presentations should make to discuss the need for cerebral biopsy in order to highlight the presence of granulomatous lesions while eliminating alternative diagnosis. Therapeutic management is based on corticosteroid therapy and immunomodulators. There are no comparative prospective study to allow us to define the first-line immunosuppressive treatment and the therapeutic strategy in refractory patients. Conventional immunosuppressants such as methotrexate, mycophenolate mofetil and cyclophosphamide are commonly used. Data on the efficacy of anti-TNFα (including infliximab) in refractory and/or severe forms are increasing during the last ten years. Additional data is necessary to assess their interest in first line in patients with severe involvement and a significant risk of relapse.

RESUMO

Uveitis in Behçet's disease (BD) is frequent (40% of cases) and is a major cause of morbidity. The age of onset of uveitis is between 20 and 30 years. Ocular involvement includes anterior, posterior or panuveitis. It is non-granulomatous. Uveitis may be the first sign of the disease in 20% of cases or it may appear 2 or 3 years after the first symptoms. Panuveitis is the most common presentation and is more commonly found in men. Bilateralisation usually occurs on average 2 years after the first symptoms. The estimated risk of blindness at 5 years is 10-15%. BD uveitis has several ophthalmological features that distinguish it from other uveitis. The main goals in the management of patients are the rapid resolution of intraocular inflammation, prevention of recurrent attacks, achievement of complete remission, and preservation of vision. Biologic therapies have changed the management of intraocular inflammation. The aim of this review is to provide an update previous article by our team on pathogenesis, diagnostic approaches, identification of factors associated with relapse and the therapeutic strategy of BD uveitis.
