Abstract
Background
Patients with rheumatoid arthritis (RA) have an increased risk of cardiovascular (CV) disease. Adiponectin is involved in the metabolism of glucose and lipids with favourable ...effects on CV disease, especially its high molecular weight (HMW) isoform. Body composition changes are described in RA with various phenotypes including obesity. The effects of tocilizumab on serum adiponectin and body composition, especially fat mass, in patients with RA are not well determined.
Methods
Patients with active RA despite previous csDMARDs and/or bDMARDs and who were tocilizumab naïve were enrolled in a multicentre open-label study. They were evaluated at baseline, 1, 3, 6 and 12 months. Clinical assessment included body mass index (BMI) and anthropometric measurements. Lipid and metabolic parameters, serum adiponectin (total and HMW), leptin, resistin and ghrelin were measured at each time point. Body composition (lean mass, fat mass, % fat, fat in the android and gynoid regions) was evaluated at baseline, 6 and 12 months.
Results
One hundred seven patients were included. Both total and HMW adiponectin significantly increased from baseline to month 3, peaking respectively at month 3 (
p
= 0.0105) and month 1 (
p
< 0.0001), then declining progressively until month 6 to 12 and returning to baseline values. Significant elevation in HMW adiponectin persisted at month 6 (
p
= 0.001). BMI and waist circumference significantly increased at month 6 and 12, as well as lean mass at month 6 (
p
= 0.0097). Fat mass, percentage fat and android fat did not change over the study period. Lipid parameters (total cholesterol and LDL cholesterol) increased while glycaemia, insulin and HOMA-IR remained stable. Serum leptin, resistin and ghrelin did not change during follow-up.
Conclusions
Tocilizumab treatment in RA patients was associated with a significant increase in total and HMW adiponectin, especially at the onset of the treatment. Tocilizumab also induced a significant gain in lean mass, while fat mass did not change. These variations in adiponectin levels during tocilizumab treatment could have positive effects on the CV risk of RA patients. In addition, tocilizumab may have an anabolic impact on lean mass/skeletal muscle.

Uveitis may be associated with various inflammatory diseases. Previous reports suggested that tumor necrosis factor (TNF) blockers, especially anti-TNF monoclonal antibodies, may reduce the incidence ...of uveitis flares in some inflammatory diseases. Under these circumstances, de novo occurrence, ie, new onset of the first episode of uveitis under anti-TNF therapy, is uncommon. Objectives The aim of this study was to collect cases of new onset of uveitis under anti-TNF therapy, using a nationwide network, to describe these cases, and to gather with cases reported in the literature. Methods All French rheumatologists, pediatric rheumatologists, and internal medicine practitioners registered on the Club Rhumatismes et Inflammation web site were contacted in an attempt to declare the cases of new onset of uveitis, diagnosed by an ophthalmologist, in patients treated with TNF blockers. The analysis of the literature was performed through PubMed database and manual research. Results Thirty-one cases were recorded, 19 men, mean age 43 (5-70) years, occurring in ankylosing spondylitis (19 cases), psoriatic arthritis (4 cases), rheumatoid arthritis (6 cases), juvenile idiopathic arthritis (2 cases). The TNF blocker at the time of uveitis was etanercept 23 times, adalimumab 3 times, infliximab 5 times, with a mean total duration of exposure to anti-TNF agents of 27 (4-96) months at uveitis occurrence. Most of the patients were good responders to TNF blockers at the time of uveitis onset. Analysis of the literature revealed 121 similar cases published in English. Conclusion Uveitis occurs de novo under anti-TNF therapy mainly in spondyloarthropathies, but also in rheumatoid arthritis and juvenile idiopathic arthritis patients and more frequently under etanercept.
Non-brucellar and non-tuberculous infectious sacroiliitis (ISI) is a rare disease, with misleading clinical signs that delay diagnosis. Most observations are based on isolated case reports or small ...case series. Our aim was to describe the clinical, bacteriological, and radiological characteristics of ISI, as well as the evolution of these arthritis cases under treatment.
This retrospective study included all ISI cases diagnosed between 1995 and 2011 in eight French rheumatology departments. ISI was diagnosed if sacroiliitis was confirmed bacteriologically or, in the absence of pathogenic agents, if clinical, biological, and radiological data was compatible with this diagnosis and evolution was favourable under antibiotic therapy.
Overall, 39 cases of ISI were identified in adults, comprising 23 women and 16 men, with a mean age at diagnosis of 39.7 ± 18.1 years. The left sacroiliac joint (SI) was affected in 59% of cases, with five cases occurring during the post-partum period. Lumbogluteal pain was the most common symptom (36/39). Manipulations of the SI joint were performed in seven patients and were always painful. Mean score for pain using the visual analogue score was 7.3/10 at admission, while 16 patients were febrile at diagnosis. No risk factor was found for 30.7% of patients. A diagnosis of ISI was only suspected in five cases at admission. The mean time to diagnosis was long, being 43.3 ± 69.1 days on average. Mean C-reactive protein was 149.7 ± 115.3 mg/l, and leukocytosis (leukocytes ≥ 10 G/l) was uncommon (n = 15) (mean level of leukocytes 10.4 ± 3.5 G/l). Radiographs (n = 33) were abnormal in 20 cases, revealing lesions of SI, while an abdominopelvic computed tomography (CT) scan (n = 27) was abnormal in 21 cases, suggesting arthritis of the SI joints in 13 cases (48.1%) and a psoas abscess in eight. Bone scans (n = 14) showed hyperfixation of the SI in 13 cases. Magnetic resonance imaging (MRI) (n = 27), when focused on the SI (n = 25), directed towards the diagnosis to ISI in 25 cases. Pathogenic agents were isolated in 33 cases (84.6%) by means of articular puncture (n = 16), blood culture (n = 14), cytobacteriological examination of urine (n = 2), or puncture of the psoas (n = 1).Gram-positive cocci were the mostly isolated common bacteria, with a predominance of staphylococci (n = 21). The most frequently isolated gram-negative bacillus was Pseudomonas aeruginosa (n = 3). Evolution was favourable in 37 out of 39 patients under prolonged antibiotic therapy (mean duration 3.01 ± 1.21 months).
Our series confirmed that the clinical manifestations of ISI usually lead to delayed diagnosis. Based on our results, we suggest performing an MRI of the spine and SI in clinical situations characterised by lumbogluteal pain and symptoms of an infectious disease, such as fever.
ObjectivesNeurological manifestations seem common in primary Sjögren's syndrome (pSS) but their reported prevalences vary. We investigated the prevalence and epidemiology of neurological ...manifestations in a French nationwide multicentre prospective cohort of patients with pSS, the Assessment of Systemic Signs and Evolution in Sjögren's syndrome (ASSESS) cohort.MethodsThe ASSESS cohort, established in 2006, includes 395 patients fulfilling American–European Consensus Group criteria for pSS. Demographic and clinical data were compared between patient groups with and without neurological manifestations, and across patient groups with peripheral nervous system (PNS) manifestations, central nervous system (CNS) manifestations and no neurological manifestations.ResultsData at inclusion were available for 392 patients, whose mean age was 58±12 years. Mean follow-up was 33.9 months. Neurological manifestations were present in 74/392 (18.9%) patients, including 63 (16%) with PNS manifestations and 14 (3.6%) with CNS manifestations. Prevalences were 9.2% for pure sensory neuropathy, 5.3% for sensorimotor neuropathy, 1.3% for cerebral vasculitis and 1.0% for myelitis. Neurological manifestations were associated with greater pSS activity as assessed using the ESSDAI (9.4±6.8 vs 4.3±4.8; p<0.001) and proportion of patients taking immunomodulatory/immunosuppressive drugs (32.4% (24/74) versus 13.8% (44/318), p=0003). New neurological symptoms were more common in patients with than without prior neurological manifestations (RR=3.918 (95% CI 1.91 to 8.05); p<0.001).ConclusionsPrevalences of peripheral and central neurological manifestations in pSS are about 15% and 5%, respectively. Neurological manifestations are associated with greater pSS activity. New neurological manifestations are more common in patients with prior neurological involvement.
ObjectivesAnti-drug antibodies (ADA) are responsible for decreased adalimumab efficacy in axial spondyloarthritis (SpA). We aimed to evaluate the ability of methotrexate (MTX) to decrease adalimumab ...immunisation.MethodsA total of 110 patients eligible to receive adalimumab 40 mg subcutaneously (s.c.) every other week were randomised (1:1 ratio) to receive, 2 weeks before adalimumab (W-2) and weekly, MTX 10 mg s.c. (MTX+) or not (MTX−). ADA detection and adalimumab serum concentration were assessed at weeks 4 (W4), 8 (W8), 12 (W12) and 26 (W26) after starting adalimumab (W0). The primary outcome was the proportion of patients with ADA at W26. Four years after the study completion, we retrospectively analysed adalimumab maintenance in relation with MTX co-treatment duration.ResultsWe analysed data for 107 patients (MTX+; n=52; MTX-; n=55). ADA were detected at W26 in 39/107 (36.4%) patients: 13/52 (25%) in the MTX+ group and 26/55 (47.3%) in the MTX− group (p=0.03). Adalimumab concentration was significantly higher in the MTX+ than MTX− group at W4, W8, W12 and W26. The two groups did not differ in adverse events or efficacy. In the follow-up study, MTX co-treatment >W26 versus no MTX or ≤W26 was significantly associated with adalimumab long-term maintenance (p=0.04).ConclusionMTX reduces the immunogenicity and ameliorate the pharmacokinetics of adalimumab in axial SpA. A prolonged co-treatment of MTX>W26 seems to increase adalimumab long-term maintenance.
To describe extra-haematological manifestations associated with human parvovirus B19 (HPV-B19) infection.
We conducted a nationwide multicentre study to retrospectively describe the characteristics ...and outcome of extra-haematological manifestations in French adults.
Data from 25 patients followed from 2001 to 2016 were analysed. Median age was 37.9 years (range: 22.7-83.4), with a female predominance (sex ratio: 4/1). Only 3 patients had an underlying predisposing condition (hemoglobinopathy or pregnancy). The most common manifestations were joint (80%) and skin (60%) involvement. Four patients (16%) had renal involvement (endocapillary proliferative or membranoproliferative glomerulonephritis, focal segmental glomerulosclerosis). Three patients (12%) had peripheral nervous system involvement (mononeuritis, mononeuritis multiplex, Guillain-Barré syndrome) and 2 (8%) presented muscle involvement. Other manifestations included hemophagocytic lymphohistiocytosis (n = 1), myopericarditis and pleural effusion (n = 1), and lymphadenopathy and splenomegaly mimicking lymphoma with spleen infarcts (n = 1). Immunological abnormalities were frequent (56.5%). At 6 months, all patients were alive, and 54.2% were in complete remission. In 2 patients, joint involvement evolved into rheumatoid arthritis. Six patients (24%) received intravenous immunoglobulin (IVIg), with a good response in the 3 patients with peripheral nervous system involvement.
HPV-B19 infection should be considered in a wide range of clinical manifestations. Although the prognosis is good, IVIg therapy should be discussed in patients with peripheral nerve involvement. However, its efficacy should be further investigated in prospective studies.
To determine the effect of education on the exercise habits of patients with rheumatoid arthritis (RA) after 6 and 12 months.
We studied 208 outpatients recruited between June 2001 and December 2002. ...This was a prospective controlled randomized trial. The active group received a multidisciplinary education program, including training in home-based exercises and guidelines for leisure physical activity (PA). The control group received a booklet added to usual medical care. Compliance with home-based exercises was defined as a practice rate >or= 30% of the prescribed training. Compliance with leisure PA was defined as >or= 20% increase in Baecke questionnaire score. Additional assessments involved possible predictors of compliance and changes with regard to the compliance.
At 6-month followup, home-based exercise and leisure PA compliance were significantly higher 13.5% vs 1%, respectively (p = 0.001); and 28.2% vs 13.8% (p = 0.02), but were not at 12 months. Predictors of leisure PA compliance at 6 months included participating in the active group (odds ratio 2.74, 95% CI 1.17 to 6.38) and previous low leisure PA (OR 6.01, 95% CI 2.47 to 14.61), with decreased fatigue (FACIT-F mean -2.94 +/- 8.04 vs -0.1 +/- 7.25 for noncompliant subjects; p = 0.04) and improved psychological status (Arthritis Impact Measurement Scale mean -1.25 +/- 3.12 vs 0.11 +/- 3.39; p = 0.03).
Education of patients with RA may increase compliance especially with leisure PA, particularly when it is poor at baseline, but these effects are limited and short-term.
To evaluate the effect on health and functional status of an 8-week group-education program for rheumatoid arthritis (RA) in addition to usual medical care.
All consecutive inpatients and outpatients ...with RA (ACR criteria) were asked to participate in this randomized, prospective, controlled trial. The educational intervention consisted of 8 weekly ambulatory sessions, each lasting 6 hours. Followup was undertaken after 1 year. The primary criterion for judging effectiveness was the Health Assessment Questionnaire (HAQ) score; secondary criteria consisted of coping, medical knowledge, patient global satisfaction, and quality of life scores before the intervention and after 1 year.
We asked 1242 inpatients and outpatients to participate in the study: 208 (16.75%) agreed (104 in each group). At baseline, there was no statistically significant difference between the 2 groups. After 1 year, no statistically significant difference was observed between the 2 groups in change in HAQ score: -0.04 +/- 0.46 (education group) vs -0.06 +/- 0.47 (control group) (p = 0.79). Statistically significant differences were found in 3 domains: patient coping (-1.22 +/- 5.55 vs -0.22 +/- 3.81; p = 0.03), knowledge (3.42 +/- 4.73 vs 0.73 +/- 3.78; p < 0.0001), and satisfaction (10.07 +/- 11.70 vs 5.72 +/- 13.77; p = 0.02), all of which were better for the group attending the education sessions.
Despite improvements in patient coping, knowledge, and satisfaction, the education program was not found to be effective at 1 year. There may have been methodological problems relating to the sensitivity of questionnaires and patient selection, and tailored educational interventions should be considered.
