Normal salivary gland ultrasonography could rule out the diagnosis of Sjögren's syndrome in anti-SSA-negative patients with sicca syndrome.

OBJECTIVE: To evaluate the relevance of salivary gland ultrasound (SGUS) and its place in the diagnostic algorithm in patients referred with dry syndrome (DS) for a suspicion of Sjögren's syndrome (SS). METHODS: We included all patients assessed at our dedicated DS clinic from June 2015 to September 2019 for which a SGUS has been carried out. Images were read blindly and the worst salivary gland was scored according to OMERACT classification. Clinical features, disease activity and treatments were collected. RESULTS: 337 patients were seen from June 2015 to September 2019. 269 patients underwent SGUS. 77 patients were diagnosed with SS and 192 did not meet the ACR/EULAR criteria for SS: non-Sjögren's DS (NSDS). Of these 192 patients, 60 had another possible cause of DS, and 132 patients were diagnosed with SAPS (sicca, asthenia, polyalgia syndrome).SGUS abnormalities were significantly higher in patients with SS versus NSDS: 51% vs 8% for a score ≥2 (p<0.0001), and 43% vs 3% for a score ≥3 (p<0.0001). SGUS score ≥2 had a specificity (Sp) of 91%, sensitivity (Se) of 57%, positive predictive value (PPV) of 72% and negative predictive value (NPV) of 82% for SS diagnosis. SGUS's characteristics in SSA-negative patients were similar to the whole population (Se=42%, Sp=91%, PPV=42%, NPV=92%). The high specificity and NPV in this population could avoid labial salivary gland biopsy (LSGB) in SSA-negative patients with normal SGUS (186 patients, 69%). CONCLUSION: SGUS is useful for SS diagnosis. If anti-SSA antibodies are negative and SGUS score <2, the diagnosis of SS is very improbable and LSGB could be avoided.

Immunization to rituximab is more frequent in systemic autoimmune diseases than in rheumatoid arthritis: ofatumumab as alternative therapy.

OBJECTIVES: The frequency and consequences of anti-drug antibodies to rituximab (RTX-ADA) are not well known in RA and even less in other systemic auto-immune diseases (sAID). We aimed to evaluate the frequency, consequences and predictive factors of RTX-ADA in RA and sAID. METHODS: All patients presenting with RA or other sAID treated with RTX from 2012 to 2017 in our tertiary reference centre for sAID were retrospectively studied. Patients who were tested for RTX-ADA were identified. RESULTS: One hundred and ninety-nine patients were treated with RTX (RA: 124, other sAID: 75). Among 62/199 (31.1%) tested for RTX-ADA, 14 were positive: 3/35 RA (8.6%) and 11/27 (40.7%) other sAID, (P = 0.0047). Among the whole RTX-treated populations, the frequency of RTX-ADA was 2.4% and 14.7% (P = 0.0026) in RA and sAID, respectively. Most of the immunized patients had infusion reactions to second or subsequent RTX cycles (11/14) and loss of efficacy (2/14). Predictive factors of immunization were sAID vs RA (78.6% vs 21.4%, P = 0.026, adjusted odds ratio (OR) = 5.35[1.43-54.75]) and African ethnicity (57.1% vs 4.2%, P < 0.001, adjusted OR = 9.25 [5.08-302.12]). Associated immunosuppressive therapy did not protect against immunization. Three patients with pSS immunized against RTX were treated with ofatumumab with complete remission of their disease. CONCLUSION: Immunization against RTX is more frequent in other sAID than in RA. Testing for RTX-ADA must be performed in patients with infusion reactions or loss of efficacy especially if they are of African origin. Immunized patients might be treated efficiently and safely with ofatumumab. This alternative should be further evaluated for sAID.

Doses of rituximab for retreatment in rheumatoid arthritis: influence on maintenance and risk of serious infection.

Objective: To investigate maintenance of rituximab (RTX) in RA patients re-treated with reduced doses compared with standard dose in a real life setting. Methods: The Autoimmunity and Rituximab (AIR) registry is a nationwide prospective observational cohort investigating the long-term safety and efficacy of RTX in RA. The present study included patients from the AIR registry that have been re-treated with RTX after a first course of RTX standard dose (1000 mg × 2). Two groups were defined according to dose of RTX of the first retreatment course (i.e. second course): standard dose group and reduced dose group. Five years' maintenance and rate of serious infections of the retreatment period were compared between standard dose and reduced dose groups. Analyses used the inverse probability of treatment weighting propensity score adjusted method. Results: Among the 1986 patients from the AIR registry, 1278 were included, 1093 (85.5%) treated with standard dose and 185 (14.5%) with reduced doses. Maintenance of RTX at 5 years in the standard and reduced groups was 55.5 and 53.8%, respectively, and did not significantly differ between groups in adjusted analyses (hazard ratio = 1.03; 95% CI: 0.81, 1.30), but the cumulative RTX dose received for retreatment [1.4 (0.6) vs 2.3 (1.0) g/year, P < 0.001] and the rate of serious infections were significantly lower in the reduced dose group (adjusted hazard ratio = 0.50; 95% CI: 0.27, 0.92; P = 0.02). Conclusion: Use of reduced doses of RTX for retreatment did not alter the maintenance of RTX at 5 years in RA patients, but allowed a 39% total dose reduction and a lower rate of serious infections.

Takayasu Arteritis and Spondyloarthritis: Coincidence or Association? A Study of 14 Cases.

OBJECTIVE: Spondyloarthritis (SpA) and Takayasu arteritis (TA) are 2 chronic inflammatory diseases; their coexistence in a single patient is uncommon. The aims of our study were to describe clinical features of patients having SpA associated with TA and to identify some characteristics of the types of patients with SpA associated with TA. We also analyzed treatments used in this context. METHODS: This French multicenter retrospective survey called for observations on behalf of the Club Rhumatismes et Inflammations, with a standardized questionnaire established by the investigators. RESULTS: We included 14 patients (women: 10/14; median age at SpA diagnosis: 43.5 yrs, ranging from 19 to 63). Subtypes of SpA were ankylosing spondylitis (n = 11), psoriatic arthritis (n = 2), and synovitis, acne, pustulosis, hyperostosis, and osteitis syndrome (n = 1). HLA-B27 was positive in 3 cases, negative in 9, and unknown in 2. SpA was diagnosed before TA in 13 cases. Imaging findings compatible with the diagnosis of TA were found with computed tomography (11/14) and/or Doppler ultrasound (10/14). Laboratory tests showed increased acute-phase reactants in all cases (C-reactive protein ≥ 25 mg/l in 71% of the cases). All patients except 1 received corticosteroids and 7 were treated with anti-tumor necrosis factor (anti-TNF). CONCLUSION: Association of SpA and TA is rare but probably not coincidental. Peripheral pulse palpation and vascular auscultation should be systematic and are the first indicators of TA in patients with SpA. Moreover, increased acute-phase reactants during SpA followup should lead to search for TA. Finally, there are therapeutic implications because anti-TNF are efficient in SpA and might be efficient in TA.

Increased Dickkopf-1 in Recent-onset Rheumatoid Arthritis is a New Biomarker of Structural Severity. Data from the ESPOIR Cohort.

Rheumatoid arthritis (RA) is the most common chronic inflammatory rheumatic condition over the world. RA is potentially disabling because chronic inflammation of the joints leads to joint destruction. To date, the best predictor of radiographic progression for patients with early RA is the presence of radiographic erosions at baseline, but a limited number of predictive biomarkers of structural progression are currently used in daily practice. Here, we investigated Dickkopf-1 (DKK-1) and sclerostin (SOST) serum levels in patients with recent inflammatory arthritis from the ESPOIR cohort. This cohort is a prospective, multicenter French cohort of 813 patients with early arthritis. We observed that mean baseline DKK-1 level was higher among RA patients with than without radiological progression within the first 2 years of evolution. DKK-1 level was still associated with radiographic progression in a model including other main predictors of severity (erosions at baseline, and anti-CCP antibody positivity). This study demonstrates that increased DKK-1 level at baseline predicted structural progression after 2-year follow-up and suggests that DKK-1 might be a new structural biomarker for early RA.

Brief Report: Monoclonal Gammopathy and Risk of Lymphoma and Multiple Myeloma in Patients With Primary Sjögren's Syndrome.

OBJECTIVE: To assess the link between monoclonal gammopathy (MG), disease activity, and incidence of malignant hematologic disorders (MHDs), including lymphoma and multiple myeloma (MM), in patients with primary Sjögren's syndrome (SS). METHODS: Screening for the presence of MG was performed in 352 primary SS patients. Each patient with MG was paired with 2 age- and sex-matched primary SS controls without MG. Their characteristics were compared for the presence of risk factors for MG and for the relationship between MG and MHD. RESULTS: Twenty-six of the 352 primary SS patients (7.4%) had MG; 88% were women, with a median age of 62.7 years (interquartile range [IQR] 50.3-69.1 years) and a median disease duration of 7.8 years (IQR 3.6-12.8 years). The parameters associated with MG on multivariate analysis were higher disease activity, as measured by either the European League Against Rheumatism Sjögren's Syndrome Disease Activity Index (ESSDAI; adjusted odds ratio [OR] 9.7, P = 0.0002) or the Clinical ESSDAI (adjusted OR 6.7, P = 0.001), and low C4 level (adjusted OR 3.4, P = 0.04). After a median follow-up of 6.3 years (IQR 3.1-9.5 years), 10 patients with MG had developed an MHD (38.5%; 4 had lymphomas and 6 had MM), as compared with 4 patients in the control group (7.7%; all had lymphomas) (OR 7.5, P = 0.002). The only factor associated with the risk of MHDs was the presence of MG (adjusted OR 5.5, P = 0.02), which was principally associated with an increased risk of MM (23% versus 0%; P = 0.0009), but not lymphoma (15% versus 8%; P = 0.3). CONCLUSION: The presence of MG was associated with higher disease activity and an increased risk of MHD in primary SS. In the presence of MG, the risk of MM was even higher than the risk of lymphoma. These results suggest that regular monitoring of primary SS patients with MG for the emergence of both lymphoma and MM is necessary.

Increase in Dickkopf-1 Serum Level in Recent Spondyloarthritis. Data from the DESIR Cohort.

OBJECTIVES: To investigate DKK-1 and SOST serum levels among patients with recent inflammatory back pain (IBP) fulfilling ASAS criteria for SpA and associated factors. METHODS: The DESIR cohort is a prospective, multicenter French cohort of 708 patients with early IBP (duration >3 months and <3 years) suggestive of AxSpA. DKK-1 and SOST serum levels were assessed at baseline and were compared between the subgroup of patients fulfilling ASAS criteria for SpA (n = 486; 68.6%) and 80 healthy controls. RESULTS: Mean SOST serum levels were lower in ASAS+ patients than healthy controls (49.21 ± 25.9 vs. 87.8 ± 26 pmol/L; p<0.0001). In multivariate analysis, age (p = 5.4 10-9), CRP level (p<0.0001) and serum DKK-1 level (p = 0.001) were associated with SOST level. Mean DKK-1 serum levels were higher in axial SpA patients than controls (30.03 ± 15.5 vs. 11.6 ± 4.2 pmol/L; p<0.0001). In multivariate analysis, DKK-1 serum levels were associated with male gender (p = 0.03), CRP level (p = 0.006), SOST serum level (p = 0.002) and presence of sacroiliitis on radiography (p = 0.05). Genetic association testing of 10 SNPs encompassing the DKK-1 locus failed to demonstrate a significant contribution of genetics to control of DKK-1 serum levels. CONCLUSIONS: DKK-1 serum levels were increased and SOST levels were decreased among a large cohort of patients with early axial SpA compared to healthy controls. DKK-1 serum levels were mostly associated with biological inflammation and SOST serum levels.

Lymphopenia in early arthritis: Impact on diagnosis and 3-year outcomes (ESPOIR cohort).

OBJECTIVES: In patients with early arthritis naive to disease-modifying antirheumatic drugs, we evaluated the prevalence of initial and persistent lymphopenia, underlying diagnoses, and risk of infection or malignancy. METHODS: Eight hundred and thirteen patients with early arthritis included in the ESPOIR cohort had a clinical examination, laboratory tests (viral serology, immunological tests, and cytokine profile), and radiographs. We determined the prevalence of lymphopenia at baseline and after 3 years, associated factors, diagnoses, and risk of infection or malignancy. RESULTS: At baseline, 50/813 (6.2%) patients had lymphopenia. Lymphopenia was associated with positive rheumatoid factor (P=0.02), cytopenia (P≤0.05), hepatitis C (P=0.05), higher C-reactive protein and DAS28 (P≤0.05 for both). Cytokine profile and radiological progression were not significantly different between patients with and without lymphopenia. Suspected diagnoses at inclusion were rheumatoid arthritis (RA, n=27), unclassified arthritis (n=15), systemic lupus erythematosus (SLE, n=3), spondyloarthritis (n=2), Sjögren's syndrome (n=1), hematologic disease (n=1), and fibromyalgia (n=1). Fifteen patients out of 42 (35.7%) with initial lymphopenia had persistent lymphopenia after 3 years, including 5 with documented causes (lupus, hepatitis C, undernutrition, azathioprine, and tamoxifen); none had PVB19, HIV, or HBV infection and none experienced infections, solid or hematologic malignancies during follow-up. Final diagnoses in these 15 patients were RA (n=6), unclassified arthritis (n=6), SLE (n=1), spondyloarthritis (n=1), and fibromyalgia (n=1). CONCLUSIONS: Lymphopenia is rare in early arthritis. The most common rheumatic cause is RA, in which marked inflammation and other cytopenias are common. Lymphopenia in early arthritis is often short-lived, even when methotrexate is prescribed.

The learning curve of nurses for the assessment of swollen and tender joints in rheumatoid arthritis.

OBJECTIVES: In rheumatoid arthritis (RA), nurses are now increasingly involved in joint count assessment but training is not standardized. The aim was to evaluate and describe the learning curve of nurses for the assessment of swollen and tender joints in RA. METHOD: Twenty nurses from university rheumatology centres inexperienced with joint counts were allocated to a rheumatologist from their centre (teacher). Acquisition of skills consisted of Phase 1: (training), a centralized 4hour training session, with (a) lecture and demonstration, and (b) practical sessions on patients with their teachers, followed by Phase 2: (practice) involving further practice on 20 patients in their own hospitals. Primary outcome was achievement of adequate swollen joint agreement between nurse and their teacher ("gold standard") at the "joint" level defined by prevalence adjusted biased adjusted kappa (PABAK)>0.60. Agreement at the "patient" level of swollen joint count (SJC), tender joint count (TJC) as well as DAS28 between nurse and their teacher were assessed with intra-class correlation coefficients (ICC). RESULTS: During the training phase, 75% of nurses achieved a swollen joint PABAK>0.60 when compared with their teachers, which further improved to 89% after the 20 practice patients (Phase 2). Median swollen joint PABAK improved from 0.64 (Q1:Q3 0.55,0.86) to 0.83 (Q1:Q3 0.77,1) by the end of Phase 2. At the "patient" level, SJC agreement remained globally stable (ICC, 0.52 to 0.66), while TJC and DAS28 agreement remained excellent throughout. CONCLUSION: Nurses inexperienced in joint counts were able to achieve excellent agreement with their teachers in assessment of tender and swollen joints through a short training session; practice further enhanced this agreement. Larger longitudinal studies are required to assess skills retention.

Improving agreement in assessment of synovitis in rheumatoid arthritis.

OBJECTIVE: Synovitis assessment through evaluation of swollen joints is integral in steering treatment decisions in rheumatoid arthritis (RA). However, there is high inter-observer variation. The objective was to assess if a short collegiate consensus would improve swollen joint agreement between rheumatologists and whether this was affected by experience. METHODS: Eighteen rheumatologists from French university rheumatology units participated in three 30 minutes rounds over a half day meeting evaluating joint counts of RA patients in small groups, followed by short consensus discussions. Agreement was evaluated at the end of each round as follows: (i) global agreement of swollen joints (ii) swollen joint agreement according to level of experience of the rheumatologist (iii) swollen joint count and (iv) agreement of disease activity state according to the Disease Activity Score (DAS28). Agreement was calculated using percentage agreement and kappa. RESULTS: Global agreement of swollen joints failed to improve (kappa 0.50 to 0.52) at the joint level. Agreement between seniors did not improve but agreement between newly qualified rheumatologists and their senior peer, which was initially poor (kappa 0.28), improved significantly (to 0.54) at the end of the consensus exercises. Concordance of DAS28 activity states improved from 71% to 87%. CONCLUSION: Consensus exercises for swollen joint assessment is worthwhile and may potentially improve agreement between clinicians in clinical synovitis and disease activity state, benefit was mostly observed in newly qualified rheumatologists.

Functional study of TNF-α promoter polymorphisms: literature review and meta-analysis.

The functional consequences of TNF-α promoter SNPs are still controversial and, to date, the functional consequences of TNF-α haplotype combinations in healthy subjects have not been assessed. In order to assess functional consequences of each TNF-α polymorphism and of their haplotype combination, TNF-α expression and secretion by LPS-stimulated monocytes from 50 healthy subjects were assessed. Monocytes were isolated and cultured for four hours, after 100  ng/mL LPS stimulation. mRNA expression was quantified using the real-time polymerase chain reaction, and TNF-α levels were measured by enzyme-linked immunosorbent assay. Each subject was genotyped for TNF-α -857 C/T, -238 G/A, -308 G/A polymorphisms. In order to confirm definitively the functional consequences of these TNF-α polymorphisms, we then performed a systematic review of the literature for TNF-α SNPs, and then a meta-analysis of the functional studies of the TNF-α -308 G/A SNP. No association between TNF-α mRNA or protein level expression, and TNF-α -238G/A, -308G/A, -857C/T polymorphisms, studied either independently or in haplotype combinations, was revealed. Using a meta-analysis for the TNF-α -308 G/A polymorphism, we confirmed the absence of any association between TNF-α mRNA and protein levels, and TNF-α -308 G/A genotypes. This study and meta-analysis of the literature confirmed the absence of any functional consequences of the TNF-α -308G/A promoter polymorphism, either alone, or in various haplotype combinations in healthy subjects.

Tumour necrosis factor alpha -308G->A polymorphism is not associated with response to TNFalpha blockers in Caucasian patients with rheumatoid arthritis: systematic review and meta-analysis.

BACKGROUND: There is a need for biomarkers that can predict anti-tumour necrosis factor (anti-TNF) treatment outcome in patients with rheumatoid arthritis (RA). Several studies have suggested that the rare A allele of the tumour necrosis factor alpha (TNFA) -308G-->A polymorphism could be associated with a poorer response to anti-TNF therapy. Nevertheless, these results remain controversial. OBJECTIVE: To determine by a meta-analysis whether the TNFA -308G-->A polymorphism is associated with response to anti-TNF treatment in patients with RA. METHODS: A bibliographic search identified studies in which the TNFA -308G-->A gene polymorphism was investigated in Caucasian patients with RA treated with anti-TNF agents. Complementary data were requested when the 28-joint count Disease Activity Score (DAS28) was not used as the primary outcome measure. Odds ratios (ORs) for response based on DAS28 and standardised mean difference (SMD) for mean improvement of DAS28 were calculated to assess the potential association between TNFA -308 genotypes and response to anti-TNF agents. RESULTS: The bibliographic search yielded 12 studies that met the inclusion criteria, which were supplemented with the data from a large Dutch cohort (n=426). The OR based on the 12 studies including 1721 patients was 1.24 (95% CI 0.98 to 1.56) and the SMD based on 11 studies including 2579 patients was -0.18 (95% CI -0.36 to 0.1). Subgroup analysis based on the two classes of anti-TNF agents did not demonstrate any association between TNFA -308 genotypes and anti-TNF treatment outcome. CONCLUSION: According to this meta-analysis, the TNFA -308 polymorphism is not a predictor of the clinical response to anti-TNF treatment in RA.

Sarcoid-like granulomatosis in patients treated with tumor necrosis factor blockers: 10 cases.

OBJECTIVE: TNF blockers have been recently evaluated for treating refractory sarcoidosis and could be efficient. However, several cases of sarcoidosis have been diagnosed during anti-TNF therapy. Here, we report the largest series of sarcoid-like granulomatosis following TNF blocker treatment. METHODS: A call for observations of sarcoid-like granulomatosis following TNF blocker treatment was sent to the members of the French 'Club Rhumatismes et Inflammation'. Histological evidence of granulomatosis was required. RESULTS: Observations of 10 patients [seven females; median age 50.5 (range 27-72) years] with sarcoid-like granulomatosis while on anti-TNF treatment were collected: five were treated with etanercept and five with monoclonal antibodies; four patients received TNF blockers for RA and six for SpA. The median delay between anti-TNF agent introduction and granulomatosis diagnosis was 18 (range 1-51) months. Clinical symptoms were mainly pulmonary and cutaneous. Angiotensin-converting enzyme activity was increased in six cases. Lymph-node and/or lung involvement were observed by CT scan of the chest for eight patients. The median delay between drug discontinuation and remission was 6 (range 1-11) months for clinical signs and 6 (range 2-12) months for biological and radiographic findings. Improvement was observed in all patients after drug discontinuation with or without steroids. CONCLUSIONS: Sarcoid-like granulomatosis is rare but not exceptional in patients treated with TNF blockers (approximately 1/2800) and does not seem to be related to gender, rheumatic disease or in our series the type of anti-TNF drug used (monoclonal antibodies or soluble receptor). Discontinuation of anti-TNF usually leads to recovery.

Effect of methotrexate and anti-TNF on Epstein-Barr virus T-cell response and viral load in patients with rheumatoid arthritis or spondylarthropathies.

INTRODUCTION: There is a suspicion of increased risk of Epstein-Barr virus (EBV)-associated lymphoproliferations in patients with inflammatory arthritides receiving immunosuppressive drugs. We investigated the EBV load and EBV-specific T-cell response in patients treated with methotrexate (MTX) or anti-TNF therapy. METHODS: Data for patients with rheumatoid arthritis (RA) (n = 58) or spondylarthropathy (SpA) (n = 28) were analyzed at baseline in comparison with controls (n = 22) and after 3 months of MTX or anti-TNF therapy for EBV load and EBV-specific IFNgamma-producing T cells in response to EBV latent-cycle and lytic-cycle peptides. RESULTS: The EBV load and the number of IFNgamma-producing T-cells after peptide stimulation were not significantly different between groups at baseline (P = 0.61 and P = 0.89, respectively). The EBV load was not significantly modified by treatment, for RA with MTX (P = 0.74) or anti-TNF therapy (P = 0.94) or for SpA with anti-TNF therapy (P = 1.00). The number of EBV-specific T cells was not significantly modified by treatment, for RA with MTX (P = 0.58) or anti-TNF drugs (P = 0.19) or for SpA with anti-TNF therapy (P = 0.39). For all patients, the EBV load and EBV-specific T cells were significantly correlated (P = 0.017; R = 0.21). For most patients, short-term exposure (3 months) to MTX or anti-TNF did not alter the EBV load or EBV-specific T-cell response but two patients had discordant evolution. CONCLUSIONS: These data are reassuring and suggest there is no short-term defect in EBV-immune surveillance in patients receiving MTX or anti-TNF drugs. However, in these patients, long term follow-up of EBV-specific T-cell response is necessary and the role of non-EBV-related mechanisms of lymphomagenesis is not excluded.

Clinical and laboratory follow-up for treating and monitoring patients with ankylosing spondylitis: development of recommendations for clinical practice based on published evidence and expert opinion.

OBJECTIVE: To develop French recommendations about the clinical and laboratory follow-up of patients with axial ankylosing spondylitis (AS) seen in everyday practice. METHODS: The recommendations were developed based on evidence from the literature and on expert opinion. A Delphi consensus procedure was used by a scientific committee to select five focal points, about which evidence was obtained by searching Medline and the databases maintained by the French Society for Rheumatology, European League against Rheumatism, and American College of Rheumatology. The results of the literature review were used by a panel of experienced rheumatologists to draft and to validate the recommendations, using expert opinion if needed to supplement gaps in published knowledge. For each recommendation, the level of evidence and the level of agreement among the experts were specified. RESULTS: The three focal points selected using the Delphi procedure dealt with choosing the best clinical and laboratory parameters for monitoring patients with AS; whether follow-up benefits from the use of composite indices (e.g., the Bath Ankylosing Spondylitis Disease Activity Index [BASDAI], the BAS Functional Index [BASFI] and the BAS Metrology Index [BASMI]); and the clinical and laboratory parameters that predict functional or structural outcomes in patients with AS. The literature search retrieved 1510 relevant articles based on titles and abstracts, of which 322 were selected for in-depth review. Five recommendations about the clinical and laboratory follow-up of patients with AS were developed then validated by having all panel participants vote during a final meeting. CONCLUSION: Recommendations about the clinical and laboratory follow-up of patients with AS were developed. They can be expected to improve clinical practice uniformity and, in the longer term, to optimize the management of patients with AS.

Pharmacotherapy (excluding biotherapies) for ankylosing spondylitis: development of recommendations for clinical practice based on published evidence and expert opinion.

OBJECTIVES: To develop recommendations about pharmacotherapy (excluding biotherapeutic agents) in patients with axial forms of ankylosing spondylitis (AS) seen in everyday clinical practice. METHODS: The recommendations were based on evidence from the literature. First, a scientific committee used a Delphi procedure to select five focal points about which recommendations were needed. Then, a literature task force looked for relevant publications in the following: Cochrane, PubMed, and Ovid databases; and abstracts from the French Society for Rheumatology, European League against Rheumatism, and American College of Rheumatology. Based on the data in these publications, recommendations were drafted then validated by a group of experts. The strength of each recommendation was determined, as well as the extent of agreement among the experts. RESULTS: The four focal points were the best strategy for using nonsteroidal anti-inflammatory drugs, role for systemic glucocorticoid therapy, role for glucocorticoid injections into the sacroiliac joints and entheses, and role for slow-acting drugs (e.g., methotrexate, sulfasalazine, leflunomide, thalidomide, and pamidronate). Of the 661 promising publications identified by the literature search, 173 were found to be relevant. The evidence in these 173 papers was reported to experts during interactive workshops. At the end of the workshops, the experts drafted recommendations, which were then validated by having all panel participants vote during a final meeting. There were seven recommendations, whose strength ranged from A to D. CONCLUSION: Seven recommendations about pharmacotherapy in patients with AS were developed. They can be expected to improve clinical practice uniformity and, in the longer term, to optimize the management of patients with AS in France.
