Fixed-flexion knee radiography: the sensitivity to detect knee joint space narrowing in osteoarthritis.

OBJECTIVES: Independent reports on the longitudinal performance of non-fluoroscopic fixed-flexion knee radiography have not been published. Therefore, we evaluated the sensitivity of fixed-flexion radiography to detect knee joint space narrowing (JSN) over 2 years in patients with osteoarthritis (OA) and compared the effect of reproducibility and quality of medial tibial plateau (MTP) alignment on sensitivity to JSN. METHODS: Fixed-flexion radiographs of both knees of 193 OA patients were obtained at baseline and after 24 months. Minimum joint space width (JSW) of the medial tibiofemoral joint spaces was measured manually in paired digitised radiographs without knowledge of the chronology. The degree of MTP alignment was assessed by measuring the distance between the anterior and posterior margins of the MTP (intermargin distance [IMD]). Accurate repositioning was achieved if, in the 24-month radiograph, the IMD was reproduced to within 1mm. The quality of MTP alignment was satisfactory if the IMD was <or=1mm. RESULTS: The mean (standard deviation [SD]) JSN between baseline and 24 months was 0.18 (0.49)mm and the standardised response mean (SRM) was 0.37. The SRM was 0.36 in the knee film pairs (86%) in which the IMD was accurately reproduced after 24 months and 0.52 in the film pairs (42%) with satisfactory MTP alignment on both the baseline and 24-month radiographs. CONCLUSION: The sensitivity to radiographic JSN on fixed-flexion knee radiographs over 2 years was higher in satisfactorily aligned than accurately reproduced serial pairs of radiographs. These findings have implications for longitudinal knee OA studies using fixed-flexion radiographs.

Consensus statement on the use of rituximab in patients with rheumatoid arthritis.

A large number of experts experienced in the treatment of rheumatoid arthritis were involved in formulating a consensus statement on the use of B cell-targeted treatment with rituximab in patients with rheumatoid arthritis. The statement was supported by data from randomised controlled clinical trials and the substantial literature on oncology. The statement underwent three rounds of discussions until its ultimate formulation. It should guide clinicians in the use of this newly approved biological agent in treating patients with rheumatoid arthritis.

Etanercept 50 mg once weekly is as effective as 25 mg twice weekly in patients with ankylosing spondylitis.

OBJECTIVE: To compare the efficacy, pharmacokinetics and safety of etanercept 50 mg once weekly with 25 mg twice weekly and placebo in patients with ankylosing spondylitis. METHODS: A 12-week, double-blind, placebo-controlled study compared the effects of etanercept 50 mg once weekly, etanercept 25 mg twice weekly and placebo in 356 patients with active ankylosing spondylitis (3:3:1 randomisation, respectively). The primary end point was the proportion of patients achieving a response at week 12 based on the Assessment in Ankylosing Spondylitis Working Group criteria (ASAS 20). The pharmacokinetics of etanercept 50 mg once weekly and 25 mg twice weekly were analysed. RESULTS: Baseline characteristics and disease activity were similar among the three groups: etanercept 50 mg once weekly, etanercept 25 mg twice weekly and placebo. The percentage of patients discontinuing therapy was 9.0%, 9.3% and 13.7% for the three respective groups. ASAS 20 response at 12 weeks was achieved by 74.2% of patients with etanercept 50 mg once weekly and 71.3% of those with etanercept 25 mg twice weekly, both significantly higher than the percentage of patients taking placebo (37.3%, p<0.001). Percentages of patients with ASAS 5/6 response (70.3%, 72.0% and 27.5%, respectively; p<0.001) and those with ASAS 40 response (58.1%, 53.3% and 21.6%, respectively; p<0.001) followed a similar pattern. Significant improvement (p<0.05) was seen in measures of disease activity, back pain, morning stiffness and C reactive protein levels as early as 2 weeks. Serum etanercept exposure was similar between the etanercept groups. Incidence of treatment-emergent adverse events, including infections, was similar among all three groups, and no unexpected safety issues were identified. CONCLUSIONS: Patients with ankylosing spondylitis can expect a comparable significant improvement in clinical outcomes with similar safety when treated with etanercept 50 mg once weekly or with 25 mg twice weekly.

Radiological damage in patients with rheumatoid arthritis on sustained remission.

OBJECTIVE: To assess the radiological damage progression in patients with recent rheumatoid arthritis in sustained remission. METHODS: A cohort of 191 patients with active early (<1 year) rheumatoid arthritis was prospectively assessed at baseline, 3 and 5 years by the Disease Activity Score (DAS) and the Sharp-van der Heijde Score (SHS) for radiographic damage. Patients in remission (DAS<1.6) at the 3-year and 5-year time points were compared with patients with a persistently active rheumatoid arthritis by Wilcoxon's signed rank test. RESULTS: 57 patients died, were lost to follow-up or had incomplete data; 30 (15.7% of those who completed) patients were in remission at 3 and 5 years. The SHS in these two groups was not significantly different at baseline (p = 0.15), but was lower in the remission group at 5 years (p = 0.0047). The median (IQR) radiographic score increased from 0.5 (0-7) at baseline to 2.5 (0-14) after 5 years for the remission group (p = 0.18) and from 2 (0-7) to 13 (3-29) in the group with active rheumatoid arthritis (p<0.001). 5 (16.7%) patients in remission had relevant progression of radiographic damage (ie, progression >4.1 points) and 6 (20%) presented new erosions in a previously unaffected joint between the third and the fifth years. CONCLUSION: Patients with early rheumatoid arthritis in sustained remission did not present statistically significant radiographic degradation at the group level; nevertheless, 16.7% of these patients did present degradation. Absence of progression should be part of the remission definition in rheumatoid arthritis.

Efficacy of tumour necrosis factor blockers in reducing uveitis flares in patients with spondylarthropathy: a retrospective study.

OBJECTIVE: To evaluate the efficacy of anti-tumour necrosis factor (TNF) treatments (given for rheumatological manifestations) in reducing uveitis flares in patients with spondylarthropathy in daily practice. METHODS: A retrospective observational study of all patients with spondylarthropathy with at least one uveitis flare treated with anti-TNF in one centre (December 1997-December 2004). The number of uveitis flares per 100 patient-years was compared before and during anti-TNF treatment; each patient was his or her own control. The relative risk (RR) and the number needed to treat (NNT) were calculated. RESULTS: 46 patients with spondylarthropathy treated with anti-TNF drugs had at least one uveitis flare (33 treated with anti-TNF antibodies, infliximab or adalimumab, and 13 with soluble TNF receptor, etanercept). The mean age at first symptoms was 26 years, 71% were men. Patients were followed for 15.2 years (mean) before anti-TNF versus 1.2 years during anti-TNF treatment. The number of uveitis flares per 100 patient-years before and during anti-TNF were, respectively: for all anti-TNF treatments,-51.8 v 21.4 (p = 0.03), RR = 2.4, NNT = 3 (95% confidence interval (CI) 2 to 5); for soluble TNF receptor-54.6 v 58.5 (p = 0.92), RR = 0.9; and for anti-TNF antibodies-50.6 v 6.8 (p = 0.001), RR = 7.4, NNT = 2 (95% CI 2 to 5). CONCLUSION: Anti-TNF treatments were efficacious in decreasing the number of uveitis flares in patients with spondylarthropathy. Anti-TNF antibodies decreased the rate of uveitis flares, whereas soluble TNF receptor did not seem to decrease this rate. These results could have consequences for the choice of anti-TNF treatment in certain patients.

Infections during tumour necrosis factor-alpha blocker therapy for rheumatic diseases in daily practice: a systematic retrospective study of 709 patients.

OBJECTIVE: To evaluate the rate of infections in rheumatic patients treated with tumour necrosis factor (TNF)-alpha blockers in daily practice and to determine potential risk factors of infections. METHODS: Systematic retrospective study was conducted in a tertiary-referral centre of all patients receiving at least one TNF-alpha blocker, between 1997 and December 2004. Serious infections were defined as life-threatening, requiring hospitalization or sequelae. The incidence of infections during the first TNF-alpha blocker course was compared with the incidence during the period just before such therapy, in the same patients and a number needed to harm was calculated. Univariate and multivariate analysis between patients who suffered from at least one infection during treatment or not, was conducted in order to determine potential associated risk factors. RESULTS: Among the 709 patients treated with at least one TNF-alpha blocker, 57.7% had rheumatoid arthritis; a total of 275 infectious events in 245 patients (34.5%) were reported during all treatment courses. Among these infections, 47 infections in 44 patients (6.2%) fulfilled the definition of serious infections. The incidence rate of serious infections was 3.4 +/- 38.7 per 100 patient-yrs before TNF-alpha blocker therapy vs 10.5 +/- 86.9 during the first TNF-alpha blocker course (P = 0.03, number needed to harm = 14). The single risk factor picked up by multivariate analysis to explain infections was previous joint surgery [odds ratio (OR) = 2.07, 95% confidence interval (CI) = (1.43-2.98), P < 0.0001] and, if surgery was taken out of the model, the cumulative dose of steroids [OR = 1.28 (1.04-1.59), P = 0.02]. CONCLUSION: The rate of serious infections during TNF-alpha blocker treatment observed in daily practice conditions was much higher than in phase III trials evaluating TNF-alpha blockers. Serious infections are frequent in daily practice and close monitoring is required.

Diagnostic and predictive value of anti-cyclic citrullinated protein antibodies in rheumatoid arthritis: a systematic literature review.

OBJECTIVE: To evaluate the two generations of anti-cyclic citrullinated protein (CCP) antibodies as a diagnostic marker of rheumatoid arthritis (RA) and as a predictor of future development of RA in healthy subjects and in patients with early undifferentiated arthritis. METHODS: A systematic analysis of the literature published between 1999 and February 2006 was conducted. Data were collected on the sensitivity and specificity of the two generations of anti-CCP antibodies for diagnosing RA and predicting future development of the disease. RESULTS: Among 107 studies initially identified, 68 had interpretable data and were analysed. Diagnostic properties were assessed in 58 studies: mean (SD) sensitivity was 53 (10)% (range 41-68) and 68 (15)% (range 39-94) for anti-CCP1 and anti-CCP2, respectively; mean (SD) specificity was 96 (3)% (range 90-99) and 95 (5)% (range 81-100) for anti-CCP1 and anti-CCP2, respectively. Predictive properties were assessed in 14 studies; odds ratio (95% confidence interval) of anti-CCP1 and anti-CCP2 for the future development of RA were 20 (14 to 31) and 25 (18 to 35), respectively, among patients with early undifferentiated arthritis and 64.5 (8.5 to 489) and 28 (8 to 95), respectively, among healthy subjects. CONCLUSION: Sensitivity of the second generation of anti-CCP is close to that of rheumatoid factor, with a higher specificity, for distinguishing RA from other rheumatic diseases. Moreover, anti-CCP antibodies appear to be highly predictive of the future development of RA in both healthy subjects and patients with undifferentiated arthritis.

A long-term, open-label trial of the safety and efficacy of etanercept (Enbrel) in patients with rheumatoid arthritis not treated with other disease-modifying antirheumatic drugs.

OBJECTIVE: To evaluate the long-term safety and efficacy of etanercept in patients with rheumatoid arthritis. METHODS: 549 patients entered this 5-year, open-label extension study and received etanercept 25 mg twice weekly. All patients showed inadequate responses to disease-modifying antirheumatic drugs before entry into the double-blind studies. Safety assessments were carried out at regular intervals. Primary efficacy end points were the numbers of painful and swollen joints; secondary variables included American College of Rheumatology (ACR) response rate, Disease Activity Score and acute-phase reactants. Efficacy was analysed using the last-observation-carried-forward approach. RESULTS: Of the 549 patients enrolled in the open-label trial, 467 (85%), 414 (75%) and 371 (68%) completed 1, 2 and 3 years, respectively; 363 (66%) remained in the study at the time of this analysis. A total exposure of 1498 patient-years, including the double-blind study, was accrued. In the open-label trial, withdrawals for efficacy-related and safety-related reasons were 11% and 13%, respectively. Frequent adverse events included upper respiratory infections, flu syndrome, rash and injection-site reactions. Rates of serious infections and malignancies remained unchanged over the course of the study; there were no reports of patients with central demyelinating disease or serious blood dyscrasias. After 3 years, ACR20, ACR50 and ACR70 response rates were 78%, 51% and 27%, respectively. The Disease Activity Score score was reduced to 3.0 at 3 months and 2.6 at 3 years from 5.1. A sustained improvement was found in Health Assessment Questionnaire scores throughout the 3-year time period. CONCLUSION: After 3 years of treatment, etanercept showed sustained efficacy and a favourable safety profile.

An international study on starting tumour necrosis factor-blocking agents in ankylosing spondylitis.

OBJECTIVES: To determine the type and proportion of patients with ankylosing spondylitis who rheumatologists consider to be candidates for treatment with tumour necrosis factor (TNF)-blocking agents, and to what extent this is in agreement with the ASsessment in Ankylosing Spondylitis (ASAS) international working group recommendations on initiation of treatment with anti-TNF agents. METHODS: Participants were rheumatologists from 10 different countries, who were considered to be experts in treating patients with ankylosing spondylitis and in the use of anti-TNF treatment, but were unaware of the ASAS recommendations (unpublished at the time of study in 2003). The first 10 consecutive patients with ankylosing spondylitis seen by the rheumatologist were evaluated as to whether the patient was a candidate for anti-TNF treatment. Thereafter, a metrologist assessed the patient for disease activity and severity, and collected data on demographics and treatment. RESULTS: Complete data were available for 1207 of the 1284 patients and were used for analysis. Overall, the rheumatologists indicated that they would initiate TNF-blocking agents in 49.3% of patients, ranging from 37.2% patients in Canada to 78.3% in Australia. These candidates had higher disease activity, higher levels of acute-phase reactants, worse spinal mobility, worse function, more often hip involvement and a higher prevalence of sick leave. Of all patients considered to be candidates, 40% did not fulfil ASAS recommendations with respect to previous use of non-steroidal anti-inflammatory drugs (NSAIDs; at least two NSAIDs) or Bath Ankylosing Spondylitis Disease Activity Index (>or=4). Conversely, 36% of patients who did not fulfil the NSAID or BASDAI recommendations were still considered to be candidates for TNF-blocking treatment. OBJECTIVE: variables, such as C reactive protein, erythrocyte sedimentation rate or magnetic resonance activity, were considered less important than disease activity in the decision on starting TNF-blocking drugs. The only important objective criterion was rapid radiographic progression. CONCLUSION: Rheumatologists wanted to initiate TNF-blocking drugs in roughly half of the patients with ankylosing spondylitis. However, there was a wide variation across countries and doctors. Rheumatologists considered both disease activity and severity to be determinants of starting TNF blockers, but their decision was often in disagreement with ASAS recommendations.

Definition of disease duration in ankylosing spondylitis: reassessing the concept.

The concept and definition of disease duration in patients with ankylosing spondylitis is ambiguous, and often many years pass between the onset of symptoms and diagnosis. Members of the Assessment in Ankylosing Spondylitis (ASAS) International Working Group by consensus recently recommended identifying specific components of the medical history to better define and document the concept of disease duration. These include (1) the time of onset of the first symptoms of axial manifestations (including inflammatory back pain); (2) the time of onset of the first symptoms of each individual manifestation, which may be an extra-axial sign or symptom of ankylosing spondylitis, such as peripheral arthritis and enthesitis; (3) the time of onset of associated diseases belonging to the spondyloarthritides, in particular acute anterior uveitis, inflammatory bowel disease and psoriasis; and (4) the time since actual diagnosis by a healthcare provider. Such uniformity in data collection will ensure comparability across studies and facilitate future research.

Continuation of treatment with infliximab in ankylosing spondylitis: 2-yr open follow-up.

OBJECTIVE: To evaluate the continuation and safety of treatment with infliximab in ankylosing spondylitis (AS) over a 2-yr period. METHODS: This study was an open, observational, 2-yr extension study of an open-label study of three induction infusions of infliximab in refractory AS. The fourth infusion was performed only in case of relapse. Thereafter, infliximab was to be administered as needed according to the rheumatologist's opinion; however, for some patients, infusions were performed systematically. RESULTS: None of the 50 recruited patients was lost to follow-up. Thirteen patients (26%) interrupted their treatment by infliximab: four for inefficacy, seven for adverse events, of which four were for allergic reactions to the infusion, and two for other reasons. For all of the 46 patients who had had three infusions judged efficacious and well tolerated, a fourth infusion was performed because of a flare of the disease, after a mean interval of 20.3+/-9.9 weeks (range 7.3-57.9). Over the 24 months, the mean interval between infusions was 11.6+/-9.0 weeks. This interval was longer when patients were treated only as needed (mean 14.3+/-12.1 weeks) than systematically (mean 9.8+/-5.7 weeks). Side-effects were similar to those noted in shorter-term studies; seven patients suffered serious adverse events. There were no deaths, no malignancies and no tuberculosis. CONCLUSION: This study confirms the long-term treatment continuation of infliximab in AS, and shows an acceptable safety profile. It appears that for some patients the disease can be controlled with long intervals between infusions; these findings warrant further studies.

EULAR recommendations for the management of early arthritis: report of a task force of the European Standing Committee for International Clinical Studies Including Therapeutics (ESCISIT).

OBJECTIVE: To formulate EULAR recommendations for the management of early arthritis. METHODS: In accordance with EULAR's "standardised operating procedures", the task force pursued an evidence based approach and an approach based on expert opinion. A steering group comprised of 14 rheumatologists representing 10 European countries. The group defined the focus of the process, the target population, and formulated an operational definition of "management". Each participant was invited to propose issues of interest regarding the management of early arthritis or early rheumatoid arthritis. Fifteen issues for further research were selected by use of a modified Delphi technique. A systematic literature search was carried out. Evidence was categorised according to usual guidelines. A set of draft recommendations was proposed on the basis of the research questions and the results of the literature search.. The strength of the recommendations was based on the category of evidence and expert opinion. RESULTS: 15 research questions, covering the entire spectrum of "management of early arthritis", were formulated for further research; and 284 studies were identified and evaluated. Twelve recommendations for the management of early arthritis were selected and presented with short sentences. The selected statements included recognition of arthritis, referral, diagnosis, prognosis, classification, and treatment of early arthritis (information, education, non-pharmacological interventions, pharmacological treatments, and monitoring of the disease process). On the basis of expert opinion, 11 items were identified as being important for future research. CONCLUSIONS: 12 key recommendations for the management of early arthritis or early rheumatoid arthritis were developed, based on evidence in the literature and expert consensus.

Molecular markers of cartilage breakdown and synovitis at baseline as predictors of structural progression of hip osteoarthritis. The ECHODIAH Cohort.

OBJECTIVE: To determine whether systemic markers of bone, cartilage, and synovium can predict structural progression of osteoarthritis (OA). METHODS: Patients with painful hip OA were treated with diacerein or placebo in a multicentre, prospective, double blind, 3 year follow up trial. The following information was collected at entry: demographics, characteristics of hip OA, and 10 markers: N-propeptides of collagen types I and III, cartilage oligomeric matrix protein, YKL-40, hyaluronan (sHA), matrix metalloproteinases-1 and -3, C reactive protein, C-terminal crosslinking telopeptides of collagen types I and II (uCTX-II). Radiographs were obtained at entry and every year. Structural progression was defined as a joint space decrease > or =0.5 mm or requirement for total hip replacement. Grouped survival analysis was performed with time to structural progression as dependent variable, and clinical data, radiographic findings, treatment groups (diacerein versus placebo), and markers as explanatory measures. RESULTS: In the 333 patients in whom all markers were measured, high functional impairment, a joint space width <2 mm, and lateral migration of the femoral head at baseline increased the risk of progression, but diacerein had a protective effect (relative risk = 0.75; 95% confidence interval (CI) 0.54 to 0.96). In addition, patients in whom uCTX-II and sHA were in the upper tertile had a relative risk of progression of 3.73 (95% CI 2.48 to 5.61) compared with patients with markers in the two lower tertiles. CONCLUSION: In this large cohort, combined measurements of uCTX-II and sHA were a new predictor of the structural progression of hip OA.

Determinants of hyperkyphosis in patients with ankylosing spondylitis.

OBJECTIVE: To determine clinical and radiographic determinants of hyperkyphosis in patients with ankylosing spondylitis. METHODS: Spinal hyperkyphosis was assessed by occiput to wall distance (OWD) in 135 patients participating in the OASIS cohort and defined as OWD >0. Disease activity was assessed by the Bath ankylosing spondylitis disease activity index (BASDAI). Wedging of the vertebrae was calculated as the Ha/Hp ratio. Structural damage of the spine was assessed by the modified Stoke ankylosing spondylitis spine score (mSASSS). Hip involvement was assessed by the Bath ankylosing spondylitis radiology index (BASRI) and defined as a score >2. Data were analysed by multiple regression analysis on van der Waerden-normal OWD values, with mean Ha/Hp ratio, mSASSS, hip involvement, and BASDAI as explanatory variables, and age, sex, and disease duration after diagnosis as covariates. RESULTS: 61 patients (45.2%) had an OWD >0 cm. Of these, 81% were male, v 57% in the group with normal OWD (p<0.001). Forty two patients had wedged thoracic vertebrae, and 27 of these (44%) had an increased OWD, compared with 15 of 74 with a normal OWD (20%) (p = 0.005). OWD was correlated with mean wedging of the thoracic spine (r = -0.45, p = 0.01), mSASSS (r = 0.56, p = 0.01), and hip involvement (r = 0.2, p = 0.05). Multivariate analysis showed that mSASSS (standardised beta (stbeta) = 0.52; p<0.001), wedging of the thoracic spine (stbeta = -0.28; p = 0.01), and BASDAI (stbeta = 0.15; p = 0.05) were independent determinants of OWD. CONCLUSIONS: Radiological damage of the cervical and lumbar spine, thoracic wedging, and disease activity are determinants of hyperkyphosis in patients with ankylosing spondylitis. These findings could be important in determining treatment goals in this disease.

Current evidence for the management of ankylosing spondylitis: a systematic literature review for the ASAS/EULAR management recommendations in ankylosing spondylitis.

OBJECTIVE: To assess available management strategies in ankylosing spondylitis (AS) using a systematic approach, as a part of the development of evidence based recommendations for the management of AS. METHODS: A systematic search of Medline, Embase, CINAHL, PEDro, and the Cochrane Library was performed to identify relevant interventions for the management of AS. Evidence for each intervention was categorised by study type, and outcome data for efficacy, adverse effects, and cost effectiveness were abstracted. The effect size, rate ratio, number needed to treat, and incremental cost effectiveness ratio were calculated for each intervention where possible. Results from randomised controlled trials were pooled where appropriate. RESULTS: Both pharmacological and non-pharmacological interventions considered to be of interest to clinicians involved in the management of AS were identified. Good evidence (level Ib) exists supporting the use of non-steroidal anti-inflammatory drugs (NSAIDs) and coxibs for symptomatic treatment. Non-pharmacological treatments are also supported for maintaining function in AS. The use of conventional antirheumatoid arthritis drugs is not well supported by high level research evidence. Tumour necrosis factor inhibitors (infliximab and etanercept) have level Ib evidence supporting large treatment effects for spinal pain and function in AS over at least 6 months. Level IV evidence supports surgical interventions in specific patients. CONCLUSION: This extensive literature review forms the evidence base considered in the development of the new ASAS/EULAR recommendations for the management of AS.

ASAS/EULAR recommendations for the management of ankylosing spondylitis.

OBJECTIVE: To develop evidence based recommendations for the management of ankylosing spondylitis (AS) as a combined effort of the 'ASsessment in AS' international working group and the European League Against Rheumatism. METHODS: Each of the 22 participants was asked to contribute up to 15 propositions describing key clinical aspects of AS management. A Delphi process was used to select 10 final propositions. A systematic literature search was then performed to obtain scientific evidence for each proposition. Outcome data for efficacy, adverse effects, and cost effectiveness were abstracted. The effect size, relative risk, number needed to treat, and incremental cost effectiveness ratio were calculated. On the basis of the search results, 10 major recommendations for the management of AS were constructed. The strength of recommendation was assessed based on the strength of the literature evidence, risk-benefit trade-off, and clinical expertise. RESULTS: The final recommendations considered the use of non-steroidal anti-inflammatory drugs (NSAIDs) (conventional NSAIDs, coxibs, and co-prescription of gastroprotective agents), disease modifying antirheumatic drugs, treatments with biological agents, simple analgesics, local and systemic steroids, non-pharmacological treatment (including education, exercise, and physiotherapy), and surgical interventions. Three general recommendations were also included. Research evidence (categories I-IV) supported 11 interventions in the treatment of AS. Strength of recommendation varied, depending on the category of evidence and expert opinion. CONCLUSION: Ten key recommendations for the treatment of AS were developed and assessed using a combination of research based evidence and expert consensus. Regular updating will be carried out to keep abreast of new developments in the management of AS.

First update of the international ASAS consensus statement for the use of anti-TNF agents in patients with ankylosing spondylitis.

OBJECTIVE: To update the international recommendations for use of anti-tumour necrosis factor (TNF) agents in the treatment of ankylosing spondylitis. METHODS: The published recommendations on anti-TNF treatment in ankylosing spondylitis formed the basis of the update. A questionnaire was sent to the ASAS (assessment in ankylosing spondylitis) members before the final decisions were agreed upon at an international meeting of the ASAS working group. RESULTS: Only minor changes to the original consensus statement were required. For the initiation of anti-TNF treatment, there should be: a diagnosis of definitive ankylosing spondylitis (normally based on modified New York criteria); active disease for at least four weeks, as defined by a sustained Bath ankylosing spondylitis disease activity index (BASDAI) of > or =4 on a 0-10 scale and expert opinion based on clinical findings; refractory disease, defined by failure of at least two non-steroidal anti-inflammatory drugs during a three month period, failure of intra-articular steroids (if indicated), and failure of sulfasalazine in patients with predominantly peripheral arthritis; and application of the usual precautions and contraindications for biological treatment. For monitoring anti-TNF treatment: both the ASAS core set for clinical practice and the BASDAI should be followed after the initiation of treatment. Discontinuation of anti-TNF treatment in non-responders should be considered after 6-12 weeks. Response is defined by improvement of at least 50% or 2 units (on a 0-10 scale) of the BASDAI. CONCLUSIONS: This updated consensus statement is recommended in guiding clinical practice and as a basis for developing national guidelines. Evaluation and regular update of this consensus statement is subject to further research by the ASAS group.
