FRI0274 HISTORY OF BIOLOGICS AND FEMALE GENDER ARE LINKED TO GOLIMUMAB DISCONTINUATION IN AXIAL SPONDYLOARTHRITIS: A SUB-ANALYSIS OF THE GO-PRACTICE STUDY

Background:

Golimumab (GLM) is the latest anti-TNFα to be indicated for treating rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA). The GO-PRACTICE study was performed in France at the request of the French Health Authorities, for the reevaluation of GLM in real-life.

Objectives:

The primary objective was to estimate GLM persistence at 2 years from initial prescription. This abstract focuses on a post-hoc analysis of the factors linked to GLM discontinuation in axSpA patients.

Methods:

Observational, prospective, multicenter study, that consecutively recruited adult patients with RA, PsA and axSpA who were newly prescribed GLM. Patients were followed-up for 2 years and outcomes data were collected at baseline (BL), 1 and 2 years. Patients’ sociodemographic characteristics, disease history, comorbidities and treatment history were also collected at BL. Persistence was estimated with the Kaplan-Meier method. Cox proportional hazard models were used to assess factors associated with persistence. Selected BL characteristics were studied in univariate models, where those associated withp-value <0.20 were included in multivariate analysis. Significance level was set atp<0.05.

Results:

478 patients with axSpA were included from Jan 2015 to Mar 2016. Mean age was 43 years and 55% were female; 61% of patients were biologic-naïve (BN, n=291) and 39% (n=187) were biologic-pretreated (BP). Median time-elapsed in years since axSpA diagnosis was 1.7 (range 0–45.1) and 6.9 (range 0.2–51.8) in BN and BP patients, respectively (P<0.001); 97% patients were prescribed 50 mg GLM monthly and co-treatments included DMARD (34%), corticosteroids (17%) and NSAIDs/analgesics (90%).

Cumulative persistence probability of GLM at 2-years was 52.6% (Fig 1). Table 1 details the binary variables associated with GLM discontinuation atp<0.20. Among continuous variables, BL CRP level was associated withp<0.20. A multivariate analysis of these factors revealed that being female (HR 1.92, 95%CI 1.43–2.56,P<0.001) and being BP (HR 1.45, 95%CI (1.11–1.90),P=0.007) were risk factors for GLM discontinuation (Table 1).

FRI0449 MANAGEMENT AND OUTCOME OF SEPTIC ARTHRITIS OF NATIVE JOINT: A NATIONWIDE SURVEY

Background:

Objectives:

To describe current management and outcome of septic arthritis on native joint in French rheumatology departments.

Methods:

Retrospective, nation-wide multicentric study. 127 French rheumatology departments were contacted to report 10 successive cases of septic arthritis on native joint that occurred between the 01/01/16 to 31/12/17 (excluding mycobacteria). Characteristics, diagnosis procedure, therapeutic management and outcome were recorded.

Results:

52 centers included 363 patients (mean age 64± 18.7 years, mean Charlson comorbidity index 4±3). 28.3% patients had a preexisting arthropathy on affected joint. Monoarthritis was observed in 89.6% patients, knee was the most frequent site (38.9%). The most frequent pathogens wereStaphylococcus sp(50.7%) andStreptococcus sp.(23.3%). Bacteremia was found in 156 (45.1%) patients and endocarditis in only 12 (3.0%). Management was heterogeneous. All patients received antibiotics for a mean duration of 46.7±22 days (including intravenous route: 17.3±15.4 d). An initial monotherapy was administered in 42.3% of patients. Surgical procedure (mostly lavage 70.6%) was performed in 171 (48.3%), joint immobilization in 128 (35.3%) (median duration of 21.7±14.1 days). 94 (29.2%) patients have had serious complications including 29 (9.5%) death. Factors associated with death are reported in the table.

Conclusion:

This study shows that management of septic arthritis is very heterogenous with a still high rate of morbidity and mortality. We identified age, comorbidities, bacteremia and recent antibiotherapy were associated with mortality. Of note, duration of antibiotics was not. Thus, new guidelines are needed in order to facilitate septic arthritis management.

THU0386 PREDICTORS OF MAINTENANCE OF SECUKINUMAB TREATMENT IN A MULTICENTER COHORT OF 561 SPONDYLARTHRITIS

Objectives:

Secukinumab (SEC) is an interleukin-17 inhibitor used to treat patients with axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA). Drug maintenance is often used as a proxy for treatment effectiveness and safety in real life settings. We aim to assess SEC maintenance in routine clinical practice and to identify survival predictors associated.

Methods:

We conducted a retrospective, longitudinal, observational, multicenter study including all patients (pts) with axSpA or PsA who received at least 1 injection of SEC between July 2016 and October 2019. We collected patient’s demographics and clinic characteristics, SEC date of initiation and dosage and dosage modification of SEC, previous biologic Disease-modifying antirheumatic drugs (bDMARDs) and concomitant treatments. Date and reasons of discontinuation – i.e., lack of efficacy, safety issue, sustained remission or others – were collected. Several potential maintenance predictors were tested: age, gender, disease (axSpA or PsA), smoking status, bDMARDs history and concomitant treatment. Among patients with non-radiographic axSpA (nr-axSpA), evidence of MRI sacroiliitis or elevated CRP were also assessed as potential maintenance predictors. Drug maintenance was analyzed by the Kaplan-Meier method and adjusted for baseline factors were estimated by log rank analysis.

Results:

The main characteristics of the 561 pts included were the following: 363 (64.7%) axSpA, 198 (35.3%) PsA, 329 (58.6%) female, mean age 45,6 +/- 12 years, 221 (39.4%) smokers, 175 (31.2%) radiographic sacroiliitis, 259 (46.2%) MRI sacroiliitis, 198 (35.3%) elevated CRP, 247 (44.0%) HLA B27 positive, mean BASDAI 48,3 +/- 26.8%. SEC was associated to methotrexate (MTX) in 139 pts (24.8%) and was the first line bDMARD in 55 pts (9.8%). The median drug maintenance (MDM) of SEC was 79 weeks (wk) [73-84]. At 52 wk, 245 pts (60%) SpA were still treated with SEC. During the 3-year follow-up, 264 pts discontinued SEC: 180 (68.2%) pts for lack of effectiveness, 47 (17.8%) for adverse events, 14 (5.3%) for others and 23 (8.7%). SEC prescription as first line bDMARD was associated with longer survival versus second line or more: 111 wk [83-138] vs. 69 wk [57-80] (p=0. 017) (figure 1). MDM was not significantly different depending on gender, MTX combo, elevated CRP, axSpA vs PsA and smoking status. Among the nr-axSpA pts, MRI sacroiliitis or elevated CRP did not modify SEC maintenance (p=0.68) (figure 2).

Conclusion:

In routine clinical practice, SEC median maintenance was 79 weeks. Fist line administration was the only independent factor associated with improved SEC retention. Lack of effectiveness was the most common reason of discontinuation.

FRI0095 SARILUMAB IMPROVED PATIENT-PERCEIVED IMPACT OF RHEUMATOID ARTHRITIS WHATEVER THE BASELINE DISEASE ACTIVITY: FIRST RESULTS FROM AN INTERVENTIONAL NON CONTROLLED STUDY: SARIPRO, IN MODERATE AND SEVERE RHEUMATOID ARTHRITIS PATIENTS

Background:

Sarilumab, an anti-IL-6R antibody, is approved for the treatment of moderate to severe RA and shown efficacy on disease activity and patient-reported outcomes (PROs). Detailed analyses of drug efficacy from the patient point of view is important. SariPRO is a pragmatic interventional study close to the daily practice.

Objectives:

To assess the effectiveness of sarilumab on several PROs using the RAID (Rheumatoid Arthritis Impact of Disease) score.

Methods:

The SariPRO study (NCT 03449758) was a French multicenter interventional study assessing the effects of sarilumab 200 mg on PROs in patients with moderately to severely active RA with an inadequate response or intolerance to conventional synthetic or biologic DMARDs. The primary endpoint was change in total RAID score from baseline to week 24 (RAID ranges 0-10 where 10 is maximal impact). Changes from baseline for RAID, DAS28-ESR and CDAI according to baseline disease activity were analyzed as secondary outcomes. Safety was assessed by monitoring adverse events (AE). All statistical analyses were descriptive, 95% CI was given when appropriate.

Results:

84 patients were included in 31 centers and 62 were evaluable and analyzed for effectiveness. They had similar characteristics to the 84 patients at baseline and were as expected for an RA population initiating a biologic: mean (SD) age: 59.9 (12.4) years, 71.0% female, disease duration 9.7 (10.3) years, rheumatoid factor positivity 82.5%, ACPA positivity 86.4%, and DAS28=4.9 (11). Total RAID score decreased significantly from 5.7 (2.0) at baseline to 3.3 (2.5) at W24; mean change was -2.4 [95% CI: -3.0; -1.8]. Furthermore, this improvement was noted both for highly and less active patients at baseline: for patients with DAS28-ESR < 5.1 (n=31), mean change was -1.56 [-2.28; -0.83] and for patients with DAS28-ESR≥5.1 (n=27), mean change was -1.98 [-2.91; -1.05]. Changes in DAS28-ESR and CDAI were significant (-2.8 [-3.2; -2.4] and -15.2 [-18.5; -11.8], respectively). AEs were consistent with the safety profile of anti-IL-6R antibodies and with results from RCTs (data not shown).

Conclusion:

In this real world study, treatment with sarilumab during 24 weeks in RA patients led to an improvement in the total RAID score irrespective of baseline levels of disease activity. This is the first time RAID score is used as the primary endpoint in a study.

FRI0348 PERSISTENCE OF SECUKINUMAB AND USTEKINUMAB IN PSORIATIC ARTHRITIS: A REAL-WORLD MULTICENTRIC COHORT OF 409 PATIENTS

Background:

Real-world data are missing for Ustekinumab (UST) and secukinumab (SEK) in psoriatic arthritis (PsA).

Objectives:

To evaluate the characteristics of the patients (pts) with PsA treated by UST or SEK and to assess real world persistence of UST and SEK in PsA.

Methods:

This is a retrospective, multicenter study of pts with PsA (CASPAR criteria or diagnosis confirmed by a rheumatologist) initiating UST or SEK with a follow-up ≥ 6 months from January 2011 to April 2019. The comparison of persistence between UST and SEK was analysed using a Cox model with an inverse probability of treatment weighting propensity score including 11 confounding factors. Subgroup analyses (age>65 years, gender, Body Mass Index (BMI), Charlson score>2, psoriasis, CRP>5mg/L, number (nb) of prior biotherapies, proportion of pts on maximum dose of UST or SEK, combination with methotrexate (MTX), enthesitic and axial forms of PsA) were also performed to test the heterogeneity of UST and SEK persistence. Finally, 2 sensitivity analyses were performed, first excluding the pts treated before the marketing authorization of SEK, and then excluding the pts that underwent a molecule switch. Causes of discontinuation were also collected.

Results:

406 pts were included: 245 with UST and 161 with SEK. At baseline before propensity score-matching, the UST group has a higher BMI (28.9 ± 6.4 kg/m2vs. 27.4 ± 6.0 kg/m2), more peripheral forms (98% vs. 90.8%), a higher nb of active smokers (27.1% vs. 19.9%), a higher frequency of psoriasis (96.3% vs. 83.2%), less MTX users (38.9% vs. 44.2%), a higher nb of pts with CRP >5mg/L (54.3% vs. 47%), a higher nb of pts naïve to biotherapies (22% vs. 13%) and a higher nb of pts with recommended dosing (97.3% vs 50.9%). The median persistence was 9.4 months and 14.7 months for UST and SEK, respectively. The persistence rate was lower in the UST group compared to the SEK group (40.9% vs. 59.1% % at 1 year; 26.4% vs. 38.0% at 2 years; weighted HR=1.42; 95% CI 1.07 to 1.92; p=0.015) (Fig 1). In subgroup analysis, combination with MTX was associated with a higher persistence rate in the patients with SEK compared to those receiving UST: 43.6% vs. 23.2% (HR=2.20; 95% CI 1.30 to 3.51; p=0.001), whereas no difference was observed in SEK and UST monotherapy: 33.8% vs 28.4%, respectively (HR=1.06; 95% CI 0.74 to 1.53; p=0.75) (Fig 2). A similar difference was found in the sensitivity analyses, with however a difference at the limit of significance for the analysis excluding pts with a molecule switch (adjusted HR=1.35; IC95% 0.96 to 1.92; p=0.085). The causes of discontinuation were due to inefficacy in 85% of cases and an adverse event in 12% of cases (19% in the SEK group and 9% in the UST group).

Conclusion:

In this first real-world study comparing UST and SEK persistence in PsA, the persistence of SEK was longer than that of UST. Subgroup analysis revealed this difference of persistence was restricted to patients treated in combination with MTX.

THU0393 INFLAMMATORY BOWEL DISEASES AMONG SECUKINUMAB-TREATED PATIENTS: 24 CASES FROM THE MISSIL REGISTRY

Background:

An alert regarding about the tolerance of Interleukin 17 (IL-17) inhibitors has been issued from data of randomized controlled trials showing cases of de novo inflammatory bowel diseases (IBD). In a recent analysis of pooled data from 21 clinical trials, cases of IBD events (including Crohn’s disease (CD), ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU)) were uncommon (1). Yet, real-world data are lacking.

Objectives:

To describe real-world data about patients treated by IL-17 inhibitors developing new onset IBD (CD or UC).

Methods:

A French national registry called MISSIL was started in February 2018 to collect the cases of patients treated by IL-17 inhibitors developing new onset IBD. This registry is conducted by rheumatologist, dermatologist and gastroenterologist learned societies specialized on immune-mediated inflammatory diseases. In France, secukinumab (SEK) has been granted market authorization since June 2016 and ixekizumab since April 2018.

Results:

24 cases under SEK were reported between February 2018 and January 2020: 3 patients with psoriasis and 21 patients with spondylwoarthritis. There were 20 patients with new onset CD and 4 with UC. Mean age was 51.7 ± 15.7 years old and 12/24 were female; 10 presented an axial spondyloarthritis, 5 a peripheral spondyloarthritis and 6 both,13/17 were HLA-B27 positive,7/19 had a radiographic sacroiliitis and 11/17 a MRI sacroiliitis. Only 2 were biological Disease-modifying antirheumatic drug (bDMARD)-naïve. Crohn’s disease was mainly located at the ileum, colon and rectum. The median time to onset of symptoms was 2 (1-6) months. The main symptoms were diarrhea, nausea and vomiting and loss of weight. Median CRP at the onset of symptoms was 68 mg/L (41-140.5); 21 patients underwent biopsies, 12 were in favor of CD. IL-17 inhibitors were consistently stopped. Patients were treated by corticosteroids (16/24), mesalazine (7/24), methotrexate (3/24), thiopurines (2/24), infliximab (9/243), adalimumab (3/24), golimumab (2/24), ustekinumab (5/24). The evolution was favorable under treatment with complete resolution (4/24), improvement (11/24) or stabilization (5/24). 3 patients worsened under treatment and 1 died (massive myocardial infarction).

Conclusion:

IBD flare in patients treated with IL-17 inhibitors are rare and lead to discuss the potential iatrogenic role of IL-17 inhibitor drugs. Further cases are needed to better characterize this complication. A case-control study will be conducted to identify patients at risk to develop IBD under IL-17 inhibitor.

Measurement of Elastase and Cysteine Proteinases in Synovial Fluid of Patients with Rheumatoid Arthritis, Sero-Negative Spondylarthropathies, and Osteoarthritis

Synovial fluid samples were collected from 45 patients with rheumatoid arthritis, spondylarthropathy, or osteoarthritis, to study their content of elastase (EC 3.4.21.37) and of cysteine proteinases (EC 3.4.22.1, 3.4.22.15). We measured both elastase complexed with alpha 1-proteinase inhibitor and elastase activity toward the substrate L-pyroglutamyl-L-prolyl-L-valine-p-nitroanilide. Cysteine proteinase activities were measured with the substrates N-benzyloxycarbonyl-L-phenylalanyl-L-arginine-7-amido-4-methylcoumarin (Z-Phe-Arg-AMC) and Z-Arg-Arg-AMC and the inhibitor E-64 [L-trans-epoxysuccinyl-leucyl-amido-(4-guanidino)-butane]. In all these enzyme assays, higher median values were obtained in inflammatory arthropathies than in osteoarthritis. The concentration of the elastase-alpha 1-proteinase inhibitor complex and of elastase and cysteine proteinase activities were statistically higher in patients with rheumatoid arthritis than in patients with osteoarthritis. The difference in results between patients with spondylarthropathy and patients with osteoarthritis was statistically significant only for the elastase-alpha 1-proteinase inhibitor complex. The median values of the complex and of both enzyme activities were higher in patients with rheumatoid arthritis than in patients with spondylarthropathy; however, the difference was statistically significant only for the cysteine proteinase activity measured with Z-Arg-Arg-AMC substrate. These results suggest that both elastase and cysteine proteinases, which are increased in patients with inflammatory arthritis, are involved in cartilage degradation in these arthropathies.

Predictive risk factors of serious infections in patients with rheumatoid arthritis treated with abatacept in common practice: results from the Orencia and Rheumatoid Arthritis (ORA) registry

OBJECTIVES

Little data are available regarding the rate and predicting factors of serious infections in patients with rheumatoid arthritis (RA) treated with abatacept (ABA) in daily practice. We therefore addressed this issue using real-life data from the Orencia and Rheumatoid Arthritis (ORA) registry.

METHODS

ORA is an independent 5-year prospective registry promoted by the French Society of Rheumatology that includes patients with RA treated with ABA. At baseline, 3 months, 6 months and every 6 months or at disease relapse, during 5 years, standardised information is prospectively collected by trained clinical nurses. A serious infection was defined as an infection occurring during treatment with ABA or during the 3 months following withdrawal of ABA without any initiation of a new biologic and requiring hospitalisation and/or intravenous antibiotics and/or resulting in death.

RESULTS

Baseline characteristics and comorbidities: among the 976 patients included with a follow-up of at least 3 months (total follow-up of 1903 patient-years), 78 serious infections occurred in 69 patients (4.1/100 patient-years). Predicting factors of serious infections: on univariate analysis, an older age, history of previous serious or recurrent infections, diabetes and a lower number of previous anti-tumour necrosis factor were associated with a higher risk of serious infections. On multivariate analysis, only age (HR per 10-year increase 1.44, 95% CI 1.17 to 1.76, p=0.001) and history of previous serious or recurrent infections (HR 1.94, 95% CI 1.18 to 3.20, p=0.009) were significantly associated with a higher risk of serious infections.

CONCLUSIONS

In common practice, patients treated with ABA had more comorbidities than in clinical trials and serious infections were slightly more frequently observed. In the ORA registry, predictive risk factors of serious infections include age and history of serious infections.

Identification of patients with gout: elaboration of a questionnaire for epidemiological studies

OBJECTIVES

In France, the prevalence of gout is currently unknown. We aimed to design a questionnaire to detect gout that would be suitable for use in a telephone survey by non-physicians and assessed its performance.

METHODS

We designed a 62-item questionnaire covering comorbidities, clinical features and treatment of gout. In a case-control study, we enrolled patients with a history of arthritis who had undergone arthrocentesis for synovial fluid analysis and crystal detection. Cases were patients with crystal-proven gout and controls were patients who had arthritis and effusion with no monosodium urate crystals in synovial fluid. The questionnaire was administered by phone to cases and controls by non-physicians who were unaware of the patient diagnosis. Logistic regression analysis and classification and regression trees were used to select items discriminating cases and controls.

RESULTS

We interviewed 246 patients (102 cases and 142 controls). Two logistic regression models (sensitivity 88.0% and 87.5%; specificity 93.0% and 89.8%, respectively) and one classification and regression tree model (sensitivity 81.4%, specificity 93.7%) revealed 11 informative items that allowed for classifying 90.0%, 88.8% and 88.5% of patients, respectively.

CONCLUSIONS

We developed a questionnaire to detect gout containing 11 items that is fast and suitable for use in a telephone survey by non-physicians. The questionnaire demonstrated good properties for discriminating patients with and without gout. It will be administered in a large sample of the general population to estimate the prevalence of gout in France.

Positivity for anti-cyclic citrullinated peptide is associated with a better response to abatacept: data from the 'Orencia and Rheumatoid Arthritis' registry

OBJECTIVES

Very limited data are available regarding the efficacy of abatacept (ABA) in real life. The aims of this study were to determine the efficacy of ABA in rheumatoid arthritis and predicting factors of efficacy in common practice.

METHODS

The Orencia and Rheumatoid Arthritis" (ORA) prospective registry, promoted by the French Society of Rheumatology, has included 1003 patients with RA.

RESULTS

773 patients had already fulfilled the 6-month follow-up visit. Only 21.3% of patients would have fulfilled inclusion criteria used in pivotal controlled trials. The European League Against Rheumatism (EULAR) response, was observed in 330 (59.1%) of the 558 assessed patients (good response: 20.4%, moderate response: 38.7%) and was similar in patients who did and in patients who did not fulfill inclusion criteria of controlled trials. Among EULAR responders, initial 28-joint disease activity score (5.4 (4.7-6.5) in responders vs 4.9 (4.0-6.0) in non responders, p< 0.0001), the proportion of rheumatoid factor (75.6% vs 66.7%, p= 0.03) and the proportion of anti-cyclic citrullinated peptide antibody (anti-CCP)-positivity (75.9% vs 62.2%, p= 0.001) were significantly higher. In multivariate analysis adjusted on initial 28-joint disease activity score and CRP, anti-CCP positivity was associated with EULAR response (OR=1.9;95% CI=1.2 to 2.9, p=0.007), but not rheumatoid factor (OR=1.0;95% CI=0.6 to 1.6, p=0.9). Anti-CCP positivity was also significantly associated with a higher ABA retention rate at 6 months.

CONCLUSIONS

Real life efficacy of ABA in the ORA registry was similar as that reported in clinical trials. Anti-CCP positivity was associated with a better response to ABA, independently from disease activity.

Clinical practice decision tree for the choice of the first disease modifying antirheumatic drug for very early rheumatoid arthritis: a 2004 proposal of the French Society of Rheumatology

OBJECTIVE

To elaborate a clinical practice decision tree for the choice of the first disease modifying antirheumatic drug (DMARD) for untreated rheumatoid arthritis of less than six months' duration.

METHODS

Four steps were employed: (1) review of published reports on DMARD efficacy against rheumatoid arthritis; (2) inventory of the information available to guide DMARD choice; (3) selection of the most pertinent information by 12 experts using a Delphi method; and (4) choice of DMARDs in 12 clinical situations defined by items selected in step 3 (28 joint disease activity score (DAS 28): < or =3.2; >3.2 and < or =5.1; >5.1; rheumatoid factor status (positive/negative); structural damage (with/without)-that is, 3 x 2 x 2). Thus, multiplied by all the possible treatment pairs, 180 scenarios were obtained and presented to 36 experts, who ranked treatment choices according to the Thurstone pairwise method.

RESULTS

Among the 77 items identified, 41 were selected as pertinent to guide the DMARD choice. They were reorganised into five domains: rheumatoid arthritis activity, factors predictive of structural damage; patient characteristics; DMARD characteristics; physician characteristics. In the majority of situations, the two top ranking DMARD choices were methotrexate and leflunomide. Etanercept was an alternative for these agents when high disease activity was associated with poor structural prognosis and rheumatoid factor positivity.

CONCLUSIONS

Starting with simple scenarios and using the pairwise method, a clinical decision tree could be devised for the choice of the first DMARD to treat very early rheumatoid arthritis.

Rat bite fever mimicking rheumatoid arthritis

We report a case of Streptobacillus moniliformis polyarthritis mimicking a rheumatoid arthritis, in a pet shop employee. In culture of fluid joint growth a curious Gram-negative bacillus was identified by polymerase chain reaction as Streptobacillus moniliformis. The outcome was good after surgical debridment and rifampin-clindamycin combination during 4 weeks.

Polyarthrite rhumatoïde et mucoviscidose

INTRODUCTION

Inflammatory arthropathies are rare complications of cystic fibrosis (CF). We describe three cases of rheumatoid arthritis (RA) occurring in patients with this disease.

OBSERVATIONS

Among the 100 patients under the care of the adult CF centre in Lille 3 presented with RA. This developed at the ages of 17, 44 and 19 years with a FEV1 of 53%, 42% and 94% respectively. They were 2 women and 1 man, with CFTR gene mutation delta F508 (1 homozygote and 2 heterozygotes) and positive sweat tests. They were colonised with Staphylococcus aureus, and rheumatoid factor and/or anti CCP antibodies were positive. The appearance and progression of RA were associated with exacerbations of bronchial infection and deterioration of respiratory function. In 2 patients the RA was continuously progressive despite intensive treatment involving high dose cortico-steroids, methotrexate (ineffective) followed by leflunomide (complicated by intractable respiratory infection).

CONCLUSION

There is an increased incidence of RA in our patient population with CF. The new serum markers of RA including anti CCP are of diagnostic interest. The evolution of the two diseases is related and seems to be dependent on the level of infection leading to therapeutic problems.

[Dropped head syndrome: report of two cases]

PURPOSE

The dropped head syndrome is characterized by an abnormal bending of the head to the body, mainly affecting old people. It corresponds to an alteration of the cervical extensor muscles, revealing in some cases a neuromuscular disease. In some cases, the etiology of this syndrome remains unknown.

EXEGESIS

We report here two cases with dropped head syndrome. The first clinical case concerned a 78-year old man, presenting a dropped head syndrome revealing a myasthenia. The syndrome disappeared with specific therapy. The second clinical case was a dropped head syndrome developed in the context of severe depressive syndrome in a 71-year old woman. The etiological screening did not reveal any underlying disease. Counteracting the syndrome was successfully obtained with early physiotherapy.

CONCLUSION

The dropped head syndrome can reveal a general disease such as myasthenia or amyotrophic lateral sclerosis. Therefore, investigation needs first to eliminate underlying diseases. If no etiology is found, the dropped head syndrome is considered of an unknown neuromuscular origin or a psychosomatic disease. In this latter case, physiotherapy may be beneficial.

Rheumatoid arthritis and schizophrenia: a negative association at a dimensional level

There is wide evidence for a decreased risk of rheumatoid arthritis in patients with schizophrenia. Nevertheless, very few studies have looked at the risk of schizophrenia in a group of patients with rheumatoid arthritis. We prospectively investigated, with the SCL-90R, 220 consecutive outpatients with rheumatoid arthritis and 196 consecutive outpatients with various medical conditions, half of them suffering from psoriatic arthritis (a medical condition close to rheumatoid arthritis). The SCL-90R appears to be a valuable tool to distinguish patients with schizophrenia from the outpatients of our sample, the former having more "paranoid ideation" (p = 0.004) and more "psychoticism" (p < 0.001) than the latter. The "paranoid ideation" dimension was significantly lower (25% decrease) in the sample of patients with rheumatoid arthritis compared to the combined control group (p = 0.005), ratings under the median value being more frequent in the former group (p = 0.025). Confounding factors might not explain this difference according to the regression logistic analysis performed. As patients with rheumatoid arthritis have a lower score of paranoid ideation than controls in our sample, even after controlling for age, gender and severity of the disease, these data represent further evidence for a decreased risk of schizophrenia in individuals with rheumatoid arthritis.

[Value of US imaging of metacarpophalangeal joints in patients with early rheumatoid arthritis]

Technological advances in the field of ultrasound imaging may have, especially in metacarpophalangeal joints, an impact on decision making in patients with early rheumatoid arthritis. First, the normal anatomy of the metacarpophalangeal joints is briefly reviewed. Then, the authors describe the main ultrasound imaging findings of early RA. The role of ultrasound imaging in the assessment of therapeutic response as well as the benefit of microbubble ultrasound contrast agents are considered.

Laboratory and imaging studies used by French rheumatologists to determine the cause of recent onset polyarthritis without extra-articular manifestations

BACKGROUND

The cause of recent onset polyarthritis can be difficult to identify.

OBJECTIVE

To determine which laboratory and imaging studies French rheumatologists recommend, not taking cost into account, for the diagnosis of recent onset polyarthritis without extra-articular manifestations.

METHODS

From the list of the French Society for Rheumatology, a random sample of 210 rheumatologists was selected, who were asked to complete a questionnaire on the laboratory and imaging studies they would recommend in two fictional cases of recent onset polyarthritis (possible rheumatoid arthritis (RA)-case 1 and probable RA-case 2).

RESULTS

In case 1, the following were recommended by over 75% of respondents: hand radiographs, rheumatoid factors (RFs), and antinuclear antibodies (ANA) (92%, 98%, and 98%, respectively). 50-74% of respondents recommended radiographs of the feet, knees, and chest (50%, 57%, and 66%, respectively); blood cell counts, erythrocyte sedimentation rate (ESR), serum assays of C reactive protein (CRP), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (65%, 74%, 67%, and 62%, respectively). 25-49% recommended determination of creatinine and proteinuria, HLA-B27, antikeratin antibody, radiographs of the pelvis, and synovial fluid analysis. Several investigations were recommended less often in case 2 than in case 1. Nevertheless, some laboratory and imaging studies (radiographs of hand, feet, knees, chest x rays, blood cell counts, ANA, RF, antikeratin antibody, CRP, ESR, creatinine, AST and ALT, proteinuria, and joint aspiration) were recommended by more than 25% of respondents in both cases.

CONCLUSION

Wide variations were found among rheumatologists, indicating a need for standardisation. Some laboratory and imaging studies are recommended by at least 25% of respondents in recent onset polyarthritis with or without clues suggesting RA. In contrast, many tests were considered useful by fewer than 25% of the respondents in both cases.

Differences in understanding and application of 1987 ACR criteria for rheumatoid arthritis and 1991 ESSG criteria for spondylarthropathy. A pilot survey

OBJECTIVES

To determine areas of agreement and disagreement among experts in the interpretation of the published criteria for RA (ACR) and spondylarthropathies ( ESSG).

METHODS

Thirty-two experts (16 from France and 16 from 10 other countries) replied anonymously to a mailed questionnaire.

RESULTS

Tenosynovitis and 'sausage-like' painless swelling of the toes were considered as criteria for RA by 18 and 14 experts, respectively. The definition of symmetry differed widely among experts (symmetry of only one group of joints was sufficient for 13). Twenty-five experts considered erosions of other joints than the wrists and fingers as a criterion for RA, 17 thought that fulfilment of criteria could be achieved cumulatively, and 19 would appreciate clarifications of the current criteria. Among possible clarifications for RA, it was frequently recommended that morning stiffness and nodules be eliminated and that new marker antibodies, X-rays of the feet, and exclusion criteria be added. Twenty-three of the 29 experts who gave an opinion (79%) agreed with the notion of SP in the absence of axial signs and sacroiliitis, 26/31 (84%) indicated that a patient can have both RA and SP, and 19/30 (63%) thought that RA and SP could be regarded as syndromes more than diseases. Only 5/32 experts relied more on the criteria than on their clinical judgement in diagnosing RA.

CONCLUSIONS

There would seem to be a needfor the optimisation of RA and ESSG criteria, particularly within the context of early arthritis.

Management of nontuberculous infectious discitis. treatments used in 110 patients admitted to 12 teaching hospitals in France

The optimal management of pyogenic discitis is not agreed on. No randomized clinical trials of short-course or oral antibiotic regimens have been published to date. To shed light on this issue, we reviewed the management of patients admitted for pyogenic discitis to one of 12 networked rheumatology departments. In this cross-sectional observational study, each department included the first ten patients admitted starting in January 1997 for treatment of pyogenic discitis. One hundred ten patients met the inclusion criteria, 67 men and 43 women, with a mean age of 60.6 +/- 13.7 years (range, 17-86 years). Mean time from symptom onset to diagnosis was 39.6 +/- 39.8 days (range, 24 h-240 days). Blood cultures were positive in 47.3% of patients, and the percutaneous discal and vertebral biopsy in 63.6% of cases; these two investigations identified the causative organism in 79 cases (72.8%). Mean duration of the rheumatology department stay was 31.3 +/- 14.1 days (range, 4-78 days). Antibiotics were given intravenously to 103 (93.6%) patients, for a mean of 25.5 +/- 17.6 days (range, 4-124 days); duration of intravenous antibiotic therapy was longer than 4 weeks in 36.5% of patients. Only seven (6.4%) patients received primary oral antibiotics with no parenteral antibiotics. One hundred patients were given oral antibiotics at the same time as and after intravenous antibiotics, for a mean duration of 87.2 +/- 43.6 day (range, 20-278 days); Bracing was used in 98 (89.1%) patients. Although antibiotic selection was rational and in agreement with current recommendations, wide differences were noted across centers regarding intravenous treatment duration, hospital stay duration, and total treatment duration.
