Objective
To report the long‐term outcome of neurologic involvement in patients with Behçet's disease (BD).
Methods
We performed a retrospective analysis of 115 patients who fulfilled the ...international criteria for BD (57% male; median age 37 years interquartile range (IQR) 30–46 years) and had neuro‐BD (NBD) after exclusion of cerebral venous thrombosis. Factors associated with relapse of NBD, inability to perform activities of daily living, and mortality were assessed.
Results
Seventy‐eight patients (68%) presented with acute NBD and 37 (32%) presented with a progressive course. The HLA–B51 allele was carried by 49% of the patients. Overall, 46 of 115 patients (40%) had severe disability at baseline, represented by a Rankin score of ≥3. The 5‐ and 7‐year event‐free survival rates were 65% and 53%, respectively. In multivariate analysis, a positive HLA–B51 status was independently associated with the risk of NBD relapse, with an odds ratio (OR) of 3.6 (95% confidence interval 95% CI 1.5–9.1). After a median followup of 73 months (IQR 59–102 months), 29 patients (25.2%) became dependent (were unable to perform activities of daily living) or died. Factors independently associated with poor outcome were paresis at onset (OR 6.47 95% CI 1.73–24.23) and location of inflammatory lesions at the brainstem on magnetic resonance imaging (OR 8.41 1.03–68.43). All 115 patients were treated with corticosteroids; 53 (46.1%) also took cyclophosphamide and 40 (34.8%) also took azathioprine. A trend toward longer event‐free survival was observed in patients with severe NBD (i.e., with a Rankin score of ≥3 at onset) receiving intravenous cyclophosphamide compared with those receiving azathioprine (P = 0.06).
Conclusion
Our findings indicate that NBD is a severe condition in which patients with the HLA–B51 allele appear to experience a worse prognosis.
Context:
Primary adrenal insufficiency due to bilateral adrenal hemorrhage-adrenal infarction is a rare and life-threatening manifestation of the antiphospholipid syndrome (APLS). Data on the ...long-term outcome are scarce.
Objective:
The aims of the present study were to analyze the long-term outcome related to APLS per se and to characterize the course of adrenal involvement.
Design:
We conducted a retrospective study of patients with bilateral adrenal hemorrhage-adrenal infarction secondary to APLS seen in the Department of Internal Medicine of Pitié-Salpêtrière Hospital in Paris (France) between January 1990 and July 2010.
Results:
Three patients died during the acute phase related to APLS manifestations. Sixteen patients (7 males; 9 females) were followed up during a median period of 3.5 years (range 0.3–28.1 years). Three episodes of recurrent thrombosis were noted. One patient died from cerebral hemorrhage 3 months after the onset of adrenal insufficiency. Repeated Synacthen tests showed complete absence of response in 8 of the 10 patients assessed; cortisol and aldosterone increased appropriately in one patient and to some extent in another one. Dehydroepiandrosterone levels and 24-hour urinary epinephrine levels remained abnormally low in all evaluated patients. Adrenal imaging performed more than 1 year after the initial event revealed completely atrophic glands in 9 of 11 patients.
Conclusions:
This particular subset of APLS patients who survive the acute phase has a rather favorable long-term outcome. Although adrenal dysfunction is generally irreversible, adrenocortical function may, at least partially, recover in rare cases. In this view, measurement of early morning cortisol during follow-up is indicated to detect these patients.
Renal biopsy is the cornerstone of systemic lupus erythematosus (SLE) nephritis and antiphospholipid syndrome (APS) nephropathy management. However, transcutaneous renal biopsy (TCRB) is hampered by ...the antithrombotic treatment frequently prescribed for those diseases. Transjugular renal biopsy (TJRB) offers an attractive alternative for patients at increased risk of bleeding. The primary objective of the study was to describe the safety profile and diagnostic performance of TJRB in SLE and APS patients.
All SLE and/or APS patients who underwent a renal biopsy in our department (between January 2004 and October 2016) were retrospectively reviewed. Major complications were death, haemostasis nephrectomy, renal artery embolization, red blood cell transfusion, sepsis and vascular thrombosis; macroscopic haematuria, symptomatic perirenal/retroperitoneal bleeding and renal arteriovenous fistula without artery embolization were considered as minor complications.
Two hundred and fifty-six TJRBs-119 without antithrombotics (untreated), 69 under aspirin and 68 on anticoagulants and 54 TCRBs without antithrombotics-were analysed. Their major and minor complication rates, respectively, did not differ significantly for the four groups: 0 and 8% for untreated TJRBs, 1 and 6% for aspirin-treated, 6 and 10% for anticoagulant-treated and 2 and 2% for TCRBs. The number of glomeruli sampled and the biopsy contribution to establishing a histological diagnosis was similar for the four groups.
TJRBs obtained from SLE and APS patients taking antithrombotics had diagnostic yields and safety profiles similar to those of untreated TCRBs. Thus, TJRB should be considered for SLE and APS patients at risk of bleeding.

Hydroxychloroquine (HCQ) is an important medication for treating systemic lupus erythematosus (SLE). Its blood concentration (HCQ) varies widely between patients and is a marker and predictor of SLE ...flares. This prospective randomised, double-blind, placebo-controlled, multicentre study sought to compare standard and adjusted HCQ dosing schedules that target HCQ ≥1000 ng/ml to reduce SLE flares.
HCQ was measured in 573 patients with SLE (stable disease and SELENA-SLEDAI≤12) treated with HCQ for at least 6 months. Patients with HCQ from 100 to 750 ng/ml were randomised to one of two treatment groups: no daily dose change (group 1) or increased HCQ dose to achieve the target HCQ (group 2). The primary end point was the number of patients with flares during 7 months of follow-up.
Overall, mean HCQ was 918±451 ng/ml. Active SLE was less prevalent in patients with higher HCQ. A total of 171 patients were randomised and followed for 7 months. SLE flare rates were similar in the two groups (25% in group 1 vs 27.6% in group 2; p=0.7), but a significant spontaneous increase in HCQ in both groups between inclusion and randomisation strongly suggested improved treatment adherence. Patients at the therapeutic target throughout follow-up tended to have fewer flares than those with low HCQ (20.5% vs 35.1%, p=0.12).
Although low HCQ is associated with higher SLE activity, adapting the HCQ dose did not reduce SLE flares over a 7-month follow-up.
To describe the pseudotumoural presentation of neuro-Behçet's disease (NBD).
We report here the main characteristics, treatment and outcome of 23 patients (5 personal cases and 18 patients from the ...literature) with a pseudotumoural presentation of NBD. Pseudotumoural NBD patients were compared with 69 consecutive patients, with a classical form of NBD.
The median age was 39 (range 27-48 years) years, with a male predominance (65.2%). Clinical features of the pseudotumoural NBD included hemi- or tetra-pyramidal symptoms (n = 20), headache (n = 17), cerebellar syndrome (n = 3), sphincter impotence (n = 3) and pseudobulbar signs (n = 2). CNS imaging showed pseudotumoural lesions mainly in the capsulo-thalamic area (69.6 vs 11.6% for classical NBD; P < 0.01). Histological analysis revealed necrotic lesions with perivascular inflammatory infiltrate without signs of tumoural or infectious lesions. Patients with pseudotumoural NBD had more severe initial disability status (Rankin's score ≥3 in 65.2 vs 24.7%; P < 0.01) and had a 3 years' longer duration between neurological signs and BD diagnosis (P = 0.01) compared with patients with classical NBD. Treatment consisted of CSs (n = 21, 95.5%) and immunosuppressive agents (n = 10, 35.7%) that led to complete clinical and imaging remission in 60.9% of patients. Two (8.7%) of the 23 patients with pseudotumoural NBD died of bedridden state complications.
The pseudotumoural form of NBD is a rare and life-threatening condition.
Objective
The determinants of vessel targeting are largely unknown in vasculitides. This study was undertaken to identify patterns of vascular involvement in Takayasu arteritis (TA), using objective ...classification of vascular beds. We postulated that cluster analysis could unveil preferential associations between vascular beds commonly affected by TA.
Methods
Peripheral vascular Doppler, computed tomography angiography, and angio–magnetic resonance imaging data from 82 patients with TA (according to the American College of Rheumatology criteria) were studied between January 1995 and May 2006. Cross‐relationships of involvement between 24 main arteries were assessed using the phi correlation coefficient. Identification of patterns of vascular involvement was performed using agglomerative hierarchical cluster analysis.
Results
Data were obtained from 82 patients (68 women 82.9% and 14 men 17.1%). The median duration of followup was 5.1 years (range 1 month to 30 years). For 16 (80%) of 20 paired arteries, the highest correlation of involvement was observed with the contralateral artery. Conversely, disease extension was contiguous in the aorta. Cluster analysis further confirmed that all paired arterial beds, except for the internal and external carotid arteries, clustered with their contralateral counterpart and that the aortic arch, the descending thoracic aorta, and the abdominal aorta clustered together.
Conclusion
Our findings reveal that TA lesions mostly develop in a symmetric manner in paired vascular territories and that disease extension is contiguous in the aorta. This may prove useful for improving the radiologic followup of patients with TA and for providing a pattern for further investigations focusing on the mechanisms of vessel specificity in vasculitides.
To compare the efficacy of methotrexate (MTX) and mycophenolate mofetil (MMF) in the prevention of relapses in neurosarcoidosis.
We conducted a retrospective multicenter study including patients who ...received MTX or MMF for the treatment of histologically proven neurosarcoidosis. The efficacy of the immunosuppressive drug was assessed by determining the time to relapse.
Forty patients with a diagnosis of neurosarcoidosis (24 men, 16 women, median age at diagnosis 43.5 years) who received at least 3 months of MTX (n = 32) or MMF (n = 14) were included. The immunosuppressive drug was always associated with steroids. The rate of relapse was 47% in the MTX group (0.2 relapses per year of exposure) and 79% in the MMF group (0.6 relapses per year of exposure) (p = 0.058). The median time to relapse was significantly shorter in the MMF group (11 months) compared with the MTX group (28 months) (p = 0.049). Adverse events occurred in 11 patients during MTX therapy and in 1 patient during MMF therapy (p = 0.12).
Relapses of neurosarcoidosis occur frequently, despite the use of an immunosuppressive drug in addition to corticosteroids. MTX significantly increases the survival time without relapse compared to MMF and should be preferred over MMF for the treatment of neurosarcoidosis. This study provides Class IV evidence that for patients with neurosarcoidosis taking steroids, MTX is superior to MMF in reducing the risk of relapse.
We conducted a single-center retrospective study to compare the characteristics of Takayasu arteritis (TA) among white, North African, and black patients in a French tertiary care center (Hospital ...Pitié-Salpêtrière, Paris). Eighty-two patients were studied (82.9% female) during a median follow-up of 5.1 years (range, 1 mo to 30 yr). Among these 82 patients, 39 (47.6%) were white, 20 (24.4%) were North African, and 20 (24.4%) were black patients. Median age at diagnosis was 39.3 years (range, 14-70 yr) in white patients vs. 28.4 years (range, 12-54 yr) in North African (p = 0.02), and 28.0 years (range, 13-60 yr) in black patients (p = 0.08). Patients aged >40 years at TA onset were more frequently white than non-white (40.0% vs. 18.6%, p = 0.03). North African patients had more frequent occurrence of ischemic stroke (p = 0.03) and poorer survival (p = 0.01) than white patients. Type V of the Hata classification was the most frequent type among white (38.5%), North African (65.0%), and black patients (40.0%). Corticosteroids were used in 96.1% of patients. Fifty-three percent of white and North African patients, and 44% of black patients required a second line of immunosuppressive treatment (p = 0.60). Vascular surgical procedures were respectively performed in 46.1%, 50.0%, and 55.0% of white, North African, and black patients, p = 0.81. The 5-year and 10-year survival rates were 100% and 95.0%, respectively, in white patients; 67.4% at both 5 years and 10 years in North African patients; and 100% at both 5 years and 10 years in black patients. This study is one of the first direct comparisons of TA profiles among patients of distinct ethnic backgrounds. Our data support the idea that late-onset TA or an overlap between TA and large-vessel giant cell arteritis may be observed in white patients. North African patients have a higher occurrence of ischemic stroke and poorer survival than white patients.
