RESUMO

OBJECTIVE: To evaluate the impact of a nurse-led program of self-management and self-assessment of disease activity in axial spondyloarthritis. METHODS: Prospective, randomized, controlled, open, 12-month trial (NCT02374749). Participants were consecutive axial spondyloarthritis patients (according to the rheumatologist) and nurses having participated in a 1-day training meeting. The program included self-management: educational video and specific video of graduated, home-based exercises for patients; and self-assessment: video presenting the rationale of tight monitoring of disease activity with composite scores (Ankylosing Spondylitis Disease activity Score, ASDAS/Bath Ankyslosing Spondylitis Disease Activity Index, BASDAI). The nurse trained patients to collect, calculate and report (monthly) ASDAS/BASDAI. Treatment allocation was by random allocation to this program or a comorbidities assessment (not presented here and considered here as the control group). RESULTS: A total of 502 patients (250 and 252 in the active and control groups, respectively) were enrolled (age: 46.7 (12.2) years, male gender: 62.7%, disease duration: 13.7 (11.0) years). After the one-year follow-up period, the adherence to the self-assessment program was considered good (i.e. 79% reported scores >6 times). Despite a lack of statistical significance in the primary outcome (e.g. coping) there was a statistically significant difference in favor of this program for the following variables: change in BASDAI, number and duration of the home exercises in the active group, and physical activity (international physical activity score, IPAQ). CONCLUSION: This study suggests a short-term benefit of a nurse-led program on self-management and self-assessment for disease activity in a young axial spondyloarthritis population in terms of disease activity, exercises and physical activity.

RESUMO

OBJECTIVES: Rheumatoid arthritis (RA) patients are at an increased risk of developing comorbid conditions. A close monitoring of the disease targeting a status of low disease activity is associated with a better outcome. The aim of this trial was to evaluate the impact of a nurse-led programme on comorbidities and the impact of patient self-assessment of disease activity on the management of RA. METHODS: We enrolled 970 patients (mean age 58 years, 79% women) in a prospective, randomised, controlled, open-label, 6-month trial. In the comorbidity group (n=482), the nurse checked comorbidities and sent the programme results to the attending physicians. In the self-assessment group (n=488), the nurse taught the patient how to calculate his/her Disease Activity Score which had to be reported on a booklet to be shared with the treating rheumatologist. The number of measures taken for comorbidities and the percentage of patients recording a change (initiation, switch or increased dose) in disease-modifying antirheumatic drugs (DMARDs) in the 6 months follow-up period of the study defined the outcomes of the trial. RESULTS: The number of measures taken per patient was statistically higher in the comorbidity group: 4.54±2.08 versus 2.65±1.57 (p<0.001); incidence rate ratio: 1.78 (1.61-1.96) and DMARD therapy was changed more frequently in the self-assessment group: 17.2% versus 10.9% (OR=1.70 (1.17; 2.49), p=0.006). CONCLUSIONS: This study demonstrates the short-term benefit of a nurse-led programme on RA comorbidity management and the impact of patient self-assessment of disease activity on RA treatment intensification. TRIAL REGISTRATION NUMBER: NCT #01315652.

RESUMO

Despite the continuing undertreatment, gout has seen something of renaissance in terms of research into epidemiology, genetics, diagnostic criteria, imaging and new treatments. In Metropolitan France, gout prevalence was estimated at 0.9 %. A recent genome-wide association study identified new loci of interest. An easy-to-use diagnostic rule for gout care shows good performance in primary care when joint fluid analysis is not available. Gout is associated with a number of comorbidities, which may have an effect on the development of gout and on the choice of therapeutic agents. Ultrasound allows non invasive and quick detection of urate microcrystals aggregates. Low-dose colchicine may be the preferred treatment option in acute gout. Agents blocking interleukin 1 (canakinumab) can be used in acute gout when NSAIDS and colchicine are contraindicated or not tolerated. Xanthine-oxydase inhibitors (allopurinol, febuxostat) are used in first line to reach the therapeutic serum urate target < 60 mg/L. Other agents under investigation are urate transporter inhibitors promoting renal uric acid excretion, such as lesinurad, and the recombinant urate pegloticase to directly catabolise urate. The combined targeting of two different modes of action has superior urate lowering effects. Patient education is essential in chronic gout management to improve adherence to treatment.

RESUMO

OBJECTIVES: To evaluate synovitis (clinical vs ultrasound (US)) to predict structural progression in rheumatoid arthritis (RA). METHODS: Patients with RA. STUDY DESIGN: Prospective, 2-year follow-up. DATA COLLECTED: Synovitis (32 joints (2 wrists, 10 metacarpophalangeal, 10 proximal interphalangeal, 10 metatarsophalangeal)) at baseline and after 4 months of therapy by clinical, US grey scale (GS-US) and power doppler (PD-US); x-rays at baseline and at year 2. ANALYSIS: Measures of association (OR) were tested between structural deterioration and the presence of baseline synovitis, or its persistence, after 4 months of therapy using generalised estimating equation analysis. RESULTS: Structural deterioration was observed in 9% of the 1888 evaluated joints in 59 patients. Baseline synovitis increased the risk of structural progression: OR=2.01 (1.36-2.98) p<0.001 versus 1.61 (1.06-2.45) p=0.026 versus 1.75 (1.18-2.58) p=0.005 for the clinical versus US-GS versus US-PD evaluation, respectively. In the joints with normal baseline examination (clinical or US), an increased probability for structural progression in the presence of synovitis for the other modality was also observed (OR=2.16 (1.16-4.02) p=0.015 and 3.50 (1.77-6.95) p<0.001 for US-GS and US-PD and 2.79 (1.35-5.76) p=0.002) for clinical examination. Persistent (vs disappearance) synovitis after 4 months of therapy was also predictive of subsequent structural progression. CONCLUSIONS: This study confirms the validity of synovitis for predicting subsequent structural deterioration irrespective of the modality of examination of joints, but also suggests that both clinical and ultrasonographic examinations may be relevant to optimally evaluate the risk of subsequent structural deterioration.

RESUMO

OBJECTIVES: To evaluate different global ultrasonographic (US) synovitis scoring systems as potential outcome measures of rheumatoid arthritis (RA) according to the Outcome Measures in Rheumatoid Arthritis Clinical Trials (OMERACT) filter. METHODS: To study selected global scoring systems, for the clinical, B mode and power Doppler techniques, the following joints were evaluated: 28 joints (28-joint Disease Activity Score (DAS28)), 20 joints (metacarpophalangeals (MCPs) + metatarsophalangeals (MTPs)) and 38 joints (28 joints + MTPs) using either a binary (yes/no) or a 0-3 grade. The study was a prospective, 4-month duration follow-up of 76 patients with RA requiring anti-tumour necrosis factor (TNF) therapy (complete follow-up data: 66 patients). Intraobserver reliability was evaluated using the intraclass correlation coefficient (ICC), construct validity was evaluated using the Cronbach alpha test and external validity was evaluated using level of correlation between scoring system and C reactive protein (CRP). Sensitivity to change was evaluated using the standardised response mean. Discriminating capacity was evaluated using the standardised mean differences in patients considered by the doctor as significantly improved or not at the end of the study. RESULTS: Different clinimetric properties of various US scoring systems were at least as good as the clinical scores with, for example, intraobserver reliability ranging from 0.61 to 0.97 versus from 0.53 to 0.82, construct validity ranging from 0.76 to 0.89 versus from 0.76 to 0.88, correlation with CRP ranging from 0.28 to 0.34 versus from 0.28 to 0.35 and sensitivity to change ranging from 0.60 to 1.21 versus from 0.96 to 1.36 for US versus clinical scoring systems, respectively. CONCLUSION: This study suggests that US evaluation of synovitis is an outcome measure at least as relevant as physical examination. Further studies are required in order to achieve optimal US scoring systems for monitoring patients with RA in clinical trials and in clinical practice.

RESUMO

OBJECTIVE: To develop French Society of Rheumatology-endorsed recommendations for the management of urate-lowering therapy (ULT). METHODS: Evidence-based recommendations were developed by 9 rheumatologists (academic or community-based), 3 general practitioners, 1 cardiologist, 1 nephrologist and 1 patient, using a systematic literature search, one physical meeting to draft recommendations and two Delphi rounds to finalize them. RESULTS: A set of 3 overarching principles and 5 recommendations was elaborated. The overarching principles emphasize the importance of patient education, especially the need for explaining the objective of lowering serum urate (SU) level to obtain crystal dissolution, clinical symptoms disappearance and avoidance of complications. ULT is indicated as soon as the diagnosis of gout is established. SU level must be decreased below 300µmol/l (50mg/l) in all gout patients or at least below 360µmol/l (60ml/l) when the 300µmol/l target cannot be reached, and must be maintained at these targets and monitored life-long. The choice of the ULT primarily relies on renal function: in patients whose estimated glomerular filtration rate (eGFR) is above 60ml/min/1.73m2, first-line ULT is allopurinol; in those with eGFR between 30 and 60ml/min/1.73m2, allopurinol use must be cautious and febuxostat can be considered as an alternative; and in those whose eGFR is below 30ml/min/1.73m2, allopurinol must be avoided and febuxostat should be preferred. Prophylaxis of ULT-induced gout flares involves progressive increase of ULT dosage and low-dose colchicine for at least 6 months. Cardiovascular risk factors and diseases, the metabolic syndrome and chronic kidney disease must be screened and managed. CONCLUSION: These recommendations aim to provide simple and clear guidance for the management of ULT in France.

RESUMO

OBJECTIVE: To develop French Society of Rheumatology-endorsed recommendations for the management of gout flares. METHODS: These evidence-based recommendations were developed by 9 rheumatologists (academic or community-based), 3 general practitioners, 1 cardiologist, 1 nephrologist and 1 patient, using a systematic literature search, one physical meeting to draft recommendations and 2 Delphi rounds to finalize them. RESULTS: A set of 4 overarching principles and 4 recommendations was elaborated. The overarching principles emphasize the importance of patient education, including the need to auto-medicate for gout flares as early as possible, if possible within the first 12h after the onset, according to a pre-defined treatment. Patients must know that gout is a chronic disease, often requiring urate-lowering therapy in addition to flare treatment. Comorbidities and the risk of drug interaction should be screened carefully in every patient as they may contraindicate some anti-inflammatory treatments. Colchicine must be early prescribed at the following dosage: 1mg then 0.5mg one hour later, followed by 0.5mg,2 to 3 times/day over the next days. In case of diarrhea, which is the first symptom of colchicine poisoning, dosage must be reduced. Colchicine dosage must also be reduced in patients with chronic kidney disease or taking drugs, which interfere with its metabolism. Other first-line treatment options are systemic/intra-articular corticosteroids, or non-steroidal anti-inflammatory agents (NSAIDs). IL-1 inhibitors can be considered as a second-line option in case of failure, intolerance or contraindication to colchicine, corticosteroids and NSAIDs. They are contraindicated in cases of infection and neutrophil blood count should be monitored. CONCLUSION: These recommendations aim to provide strategies for the safe use of anti-inflammatory agents, in order to improve the management of gout flares.

RESUMO

OBJECTIVE: To evaluate the impact of a nurse-led program of systematic screening for the management (detection/prevention) of comorbidities. METHODS: Prospective, randomized, controlled, open, 12-month trial (NCT02374749). PARTICIPANTS: consecutive patients with axial Spondyloarthritis (axSpA) (according to the rheumatologist) THE PROGRAM: A nurse collected data on comorbidities during a specific outpatient visit. In the event of non-agreement with recommendations, the patient was informed and a specific recommendation was given to the patient (orally and in a with a detailed written report). Patients were seen after one year in a nurse-led visit. TREATMENT ALLOCATION: random allocation (i.e. either this program or an educational program not presented here and considered here as the control group). MAIN OUTCOME: change after one year of a weighted comorbidity management score (0 to 100 where 0= optimal management). RESULTS: 502 patients were included (252 and 250 in the active and control groups, respectively): age: 47±12 years, male gender: 63%, disease duration: 14±11y. After one year, no differences were observed in a weighted comorbidity management score. However, the number of patients in agreement with recommendations was significantly higher in the active group for vaccinations (flu vaccination: 28.6% vs. 9.9%, p<0.01; pneumococcal vaccination:40.0% vs. 21.1%,p=0.04), for cancer screening (skin cancer screening: 36.3% vs. 17.2%, p=0.04) and for osteoporosis (bone densitometry performed: 22.6% vs. 8.7%, p<0.01; Vitamin D supplementation initiation: 51.9% vs. 9.4%, p<0.01). CONCLUSIONS AND RELEVANCE: This study suggests the short-term benefit of a single-visit nurse-led program for systematic screening of comorbidities for its management in agreement with recommendations, even in this young population of patients with axSpA.

RESUMO

The definition of asymptomatic hyperuricemia remains unclear, as no consensus exists about the serum urate cutoff or the relevance of ultrasound findings. Comorbidities associated with hyperuricemia have increased in frequency over the past two decades. Hyperuricemia (and/or gout) may be a cause or a consequence of a comorbidity. Whereas epidemiological studies suggest that hyperuricemia may be linked to cardiovascular, metabolic, and renal comorbidities, Mendelian randomization studies have not provided proof that these links are causal. Discrepancies between findings from observational studies and clinical trials preclude the development of recommendations about the potential benefits of urate-lowering therapy (ULT) in individual patients with asymptomatic hyperuricemia. The risk/benefit ratio of ULT is unclear. The risk of developing gout, estimated at 50%, must be weighed against the risk of cutaneous and cardiovascular side effects of xanthine oxidase inhibitors. The need for optimal comorbidity management, in contrast, is universally accepted. Medications for comorbidities that elevate urate levels should be discontinued and replaced with medications that have the opposite effect. Therapeutic lifestyle changes, weight loss as appropriate, and sufficient physical activity are useful for improving general health. Whether ULT has beneficial effects on comorbidities will be known only when well-powered interventional trials with relevant primary endpoints are available.

RESUMO

Bone microarchitecture is an important determinant of the fracture risk, independently of bone mineral density. At present, bone biopsy is required for microarchitecture assessment, and accessible non-invasive techniques are needed. In this study, we tested the short-term reproducibility and parameter changes of a non-invasive method for microarchitecture assessment with a medical computed tomography. Texture parameters (run lengths and co-occurrence) were extracted from bone sample images. Reproducibility and the influence of slice thickness (1, 3, 5 and 8mm) were also studied. After five repositionings, short-term reproducibility was found to be good. All run length parameters but one fell significantly with increasing slice thickness. Co-occurrence parameters showed different patterns of change. Short-term coefficients of variation of texture parameters used to assess bone microarchitecture were similar to those obtained elsewhere with other techniques. The results were influenced by slice thicknesses, emphasizing the importance of the conditions of acquisition.

RESUMO

Microarchitecture of trabecular bone is a very important component of bone quality in osteoporosis and a determinant of vertebral fracture in men with low bone mineral density (BMD). In contrast to women, male osteoporosis is, in most cases, secondary. The relationships between microarchitecture and different risk factors have never been evaluated in men. About 152 men with low BMD at the lumbar spine or hip (BMD, T-score < -2.5) were included in this study. Risk factors were: age, BMI, alcohol intake, corticosteroid therapy, hypogonadism, and chronic diseases. Transiliac bone biopsies were obtained and histomorphometry was done on an image analyzer; the following parameters were measured: cortical thickness (Ct.Th), trabecular bone volume (BV/TV), trabecular thickness (Tb.Th), separation (Tb.Sp) and number (Tb.N), interconnectivity Index (ICI), star volume of the bone marrow, and strut analysis with node and free-end count. The 50 men with two risk factors had a lower BMD, lower Ct.Th and a significant higher star volume than those with one factor or idiopathic osteoporosis. The 26 men with at least three risk factors, had a lower BMD, a reduction of BV/TV and Ct.Th and a marked disorganization of the trabecular network (increased Tb.Sp, ICI, star volume, and free-end to free-end struts). The prevalence of vertebral fractures was higher in these patients. When the main risk factor was considered, a marked decrease in trabecular bone connectivity was observed in hypogonadic men. In osteoporotic men, higher the number of risk factors, lower the connectivity of trabecular network and higher the vertebral fracture risk.

RESUMO

Rheumatic manifestations of genetic hemochromatosis are frequent. These manifestations are characterized by articular damage and osteoporosis. Clinicians must be aware of these presentations because they are sometimes the initial manifestation of hemochromatosis. Moreover, rheumatic pain causes substantial discomfort for patients and diminishes their quality of life.

RESUMO

OBJECTIVES: Hyperuricemia is becoming increasingly frequent in the population, and is known to be sometimes the cause of gout. The impact of uric acid is still not clearly understood, however. The iron metabolism may interact with the uric acid metabolism. The aim of this study was to examine the relationship between the serum uric acid and serum ferritin levels in a cohort of hemochromatosis patients who were homozygous for the HFE p.Cys282Tyr mutation. METHODS: 738 patients with the HFE gene mutation Cys282Tyr in the homozygous state were included in the study. The variables measured during the initial evaluation were compared in univariate analysis by Student's t test. In multivariate analysis, linear stepwise regression was used. RESULTS: In the group of hyperuricemic patients, ferritinemia was significantly higher than in the group of non-hyperuricemic patients (1576.7±1387.4µg/l vs. 1095.63±1319.24µg/l, P<0.005). With multivariate analysis, only ferritin and BMI independently explained the uricemia (R2=0.258) after adjustment for age, glycemia and CRP. The correlation between uricemia and log(ferritin) with partial regression correlation coefficients was 0.307 (P<0.01). CONCLUSIONS: The increase in uricemia is associated with the increase in ferritin in a population of patients who were homozygous for the HFE gene mutation p.Cys282Tyr and this independently of factors commonly associated with hyperuricemia. The increase in uric acid associated with hyperferritinemia, could be a response to the visceral toxicity of excess non-transferrin bound iron linked to oxidative stress via the antioxidant properties of uric acid.

RESUMO

OBJECTIVES: The allopurinol dose is limited in chronic kidney disease, particularly stage 4/5 chronic kidney disease. Febuxostat has a hepatic metabolism and has been approved without dose adaptation in gouty patients with stage 1-3 chronic kidney disease. We aimed to study the safety and efficacy of febuxostat for stage 4/5 chronic kidney disease. METHODS: In this retrospective study, we included patients with (1) a diagnosis of gout, (2) febuxostat treatment, (3) estimated glomerular filtration rate≤30mL/min/1.73m2 (Modification of Diet in Renal Disease formula) at febuxostat initiation and (4) follow-up for at least 3 months after febuxostat initiation. Efficacy, safety and variation in estimated glomerular filtration rate were analyzed. RESULTS: We included 73 patients (mean age 70.2±11.8, 61 men, 31 with vascular chronic kidney disease and 18 renal transplantation) with gout (baseline serum uric acid level=9.86±2.85mg/dL, mean gout duration 6.2±7.0 years) from 10 academic centers. Comorbidities included cardiac failure (17.8%), hypertension (98.6%), diabetes mellitus (30.1%), dyslipidemia (64.8%) and history of cardiovascular events (38.4%). At the last visit (mean follow-up 68.5±64.8 weeks), the daily dose of febuxostat was 40mg for 7 patients (10.5%), 80mg for 50 (74.6%) and 120mg for 10 (14.9%). Serum uric acid level was<6mg/dL for 49 patients (67%). Renal function improved for 18 patients, was unchanged for 24 and worsened for 31; 19 patients experienced flares and 1 patient, limb edema. CONCLUSION: Febuxostat seemed efficient in gouty patients with stage 4/5 chronic kidney disease. However, safety data were not clear regarding renal function. Larger studies are needed to assess safety.

RESUMO

Arthropathy is a major and distinctive manifestation of hemochromatosis, resembling degenerative joint disease with involvement of unusual articular sites, almost identical to the arthropathy in calcium pyrophosphate dihydrate crystals deposition disease (chondrocalcinosis), associated with osteoporosis.
