20812156 [Arthritis of the atlanto-axial joint with inflammatory neck pain as a primary manifestati 2010 Sep HISTORY AND ADMISSION FINDINGS: A 68-year-old woman with known degenerative joint disease suffered from increasing neck pain. Physical examination revealed painfully restricted movement of the cervical spine. INVESTIGATIONS: Erythrocyte sedimentation rate and C-reactive protein were increased. Tests for rheumatoid factors, antinuclear, anti-citrullinated protein and anti-neutrophil cytoplasmic antibody were negative. Cervical spine x-ray showed osteochondrosis with partially bridging spondylosis at C5/C6, but there was no atlanto-axial dislocation. Magnetic resonance imaging (MRI) revealed bone marrow edema and hyperintensity of the odontoid process, but there were no indications of fissures or fracture lines. TREATMENT AND COURSE: These findings indicated seronegative rheumatoid arthritis, with predominantly active atlanto-axial arthritis. After methotrexate and prednisolone had been administered the symptoms improved rapidly and inflammatory parameters returned to normal. Three months later no atlanto-axial arthritis was seen at MRI. CONCLUSION: Rheumatoid arthritis involving the atlanto-axial region should be considered in patients with persisting neck pain and signs of inflammation.
20888443 PTPN22 1858C>T polymorphism is strongly associated with rheumatoid arthritis but not with 2010 Dec PTPN22 (protein tyrosine phosphatase non-receptor type 22) 1858C>T single-nucleotide polymorphism (SNP) is one of the genetic risk factors of rheumatoid arthritis (RA). However, its role in the response of RA patients to therapy is not known. We examined a possible association of this SNP with a response of RA patients to methotrexate (MTX) treatment. RA was diagnosed in 371 patients according to the American College of Rheumatology (ACR) criteria. All 371 patients were typed for PTPN22 1858C>T SNP. Clinical data for 308 patients treated with MTX were available. Clinical improvement was evaluated according to the ACR 20% response criteria. Five hundred and forty three unrelated healthy individuals served as a control group. DNA was isolated from venous blood and 1858C>T SNP was established by polymerase chain reaction followed by restriction fragment length polymorphism using XcmI digestion. One hundred and seventy four patients responded to MTX with remission of symptoms, whereas 134 individuals were not responding. Although 78.6% of patients with 1858TT genotype responded to MTX in contrast to 49.5% and 58.1% of CT and CC genotype bearers, respectively, this difference was nonsignificant due to very low numbers of TT homozygotes in both groups of patients. We confirmed strong association of 1858T allele with RA and with a disease limited to joints, but did not observe any association with a lack of rheumatoid factor, described earlier for a smaller population sample. However, the response of RA patients to MTX treatment does not seem to depend on this SNP.
19459564 [Influence of balneophysical therapy on activity, functional capacity, and quality of life 2009 Mar INTRODUCTION: It has been well known that balneophysical therapy has a therapeutic effect on clinical and biological parameters of disease activity in the patients with rheumatoid arthritis (RA). OBJECTIVE: To determine the influence of balneophysical therapy on functional capacity, activity and quality of life of the patients with RA primarily treated with some of disease modifying antirheumatic drugs. METHODS: The study enrolled 73 patients with RA treated with some of disease modifying antirheumatic drugs (Methotrexate in 85% of patients). During hospitalization at the Clinical Rheumatologic Department of the Institute "Niska Banja", the patients were treated, beside the medicamentous therapy, by hydrotherapy (oligomineral, homeothermic, low radioactive water), mineral peloid therapy, electrotherapy and kinesiotherapy. Before and after balneotherapy, the patients filled in the Health Assessment Questionnaire (HAQ) and the Quality of Life Rheumatoid Arthritis (QOL-RA) scale. The Disease Activity Score (DAS) 28 was used to measure the disease activity before and after balneotherapy. A possible value of HAQ was from 0 to 3, and QOL-RA from 0 to 10. RESULTS: The mean value of the duration of balneophysical therapy was 14.7 +/- 4.8 days. We found significant improvement of functional capacity in the patients with RA. The average HAQ score before balneotherapy was 1.07 +/- 0.61, and 0.86 +/- 0.55 after balneotherapy, which was statistically significantly lower (p < 0.05). DAS 28 after balneotherapy was also statistically significantly lower than DAS 28 before balneotherapy: the mean value of DAS 28 before therapy was 6.30 +/- 0.81 and after therapy 5.48 +/- 0.75 (p < 0.001). The quality of life significantly improved after balneophysical therapy: the mean value of QOL-RA scale before therapy was 5.38 +/- 1.62 and after therapy 7.35 +/- 1.81 (p < 0.05). CONCLUSION: Balneophysical therapy, when properly dosed, is an effective, adjuvant therapy in the patients with RA of mild disease activity. Balneophysical therapy has a positive influence on disease activity, functional capacity and quality of life in the patients with rheumatoid arthritis.
19449475 [Diagnosis and therapeutical management offered to rheumatoid arthritis patients in Brazil 2009 Jan OBJECTIVES: The aim of this study was to evaluate in relation to diagnosis and treatment for Rheumatoid Arthritis (RA) patients Brazilian population, and compare the management offered to patients who are followed up in the public and private sectors. MATERIAL AND METHODS: An electronic questionnaire was sent to 650 rheumatologists, members of the Brazilian Rheumatology Society (SBR) and who were attending adult RA patients in the public and/or private sector, who had a contact e-mail address available in the SBR register and agreed to take part in the survey. RESULTS: The rheumatologists estimated that 51.7% of the patients had had their disease diagnosed and of these, 56.1% were undergoing treatment. It was also estimated that 53.9% of the RA patients that was under treatment were being followed up by rheumatologists. The mean time interval estimated by the rheumatologists, between the appearance of the first symptoms of RA and the diagnosis made by a doctor, was greater among the patients who sought attendance in public services (1.8 years). There was no difference in clinical and radiographic assessment measures between the two types of service, with the exception of the application of HAQ, which was used more in public services. The principal drug association reported in both types of services was methotrexate and chloroquine. The rate of usage of associations between biological agents and methotrexate ranged from 6 to 8%. The main treatment-related difficulties were: access to the health system (public services) and cost of medication (private services). CONCLUSION: Approximately 50% of RA patients are being diagnosed and half of these are under treatment. There was no great difference in attendance within the public and private systems for these patients, whereas the main difficulty for the public system was access to attendance, for the private system it was the cost of the medication.
19902562 Purine biosynthetic pathway genes and methotrexate response in rheumatoid arthritis patien 2009 Oct OBJECTIVE: Inter-individual variations to methotrexate (MTX) response among rheumatoid arthritis (RA) patients have been attributed to clinical heterogeneity and genetic variations influencing MTX pharmacology. In this study, we analyzed the association of polymorphisms in ATIC, AMPD1, ADA, and ADORA2A from the purine biosynthetic pathway with MTX response in RA patients from north India. We also assessed the cumulative contribution of these polymorphisms together with those from the receptor-metabolizer-transporter and folate pathway genes that we have previously investigated. METHODS: RA patients recruited using the American College of Rheumatology criteria were grouped into good (n = 213) and poor (n = 68) responders to MTX, based on Disease Activity Score 28-3. Individual single nucleotide polymorphism association was tested using (chi)2 test, and cumulative contribution of all the single-nucleotide polymorphisms and cumulative contribution of all the SNPs and clinico-demographic factors were assessed using linear and logistic regression. RESULTS: G allele of ADA rs244076 [P = 0.02, odds ratio (95% confidence interval): OR (95% CI) = 1.66 (1.01-2.75)]; and T allele of ADORA2A rs5751876 [P = 0.04, OR (95% CI) = 1.55 (1.01-2.37)] were associated with poor response, but did not stand Bonferroni correction. On regression analyses, FPGS rs1544105, TYMS rs2853539, DHFR rs7387, and ADA rs244076 were identified as putative predictors for MTX response. Carriers of the FPGS rs1544105 AA and AG genotypes [OR (95% CI) = 3.47 (1.19-10.12)] and TYMS rs2853539 AA genotype [OR (95% CI) = 2.76 (1.50-5.07)] were predictors of poor response in our patient population. CONCLUSION: Genes from all the three pathways seem to contribute to MTX response in the Indian population. However, these observations need to be replicated in an independent sample set.
19701637 Clinical efficacy of tocilizumab in patients with active rheumatoid arthritis in real clin 2010 Jun The previous clinical studies have demonstrated tocilizumab monotherapy to be highly effective in rheumatoid arthritis (RA). The objectives of the present article are to report the efficacy and safety of tocilizumab in patients with active RA in real clinical practice. In total, 61 patients with RA were treated with tocilizumab. Any comorbidities they had, especially infections, were treated thoroughly before they were given the drug. We provided guidance on infection control and prevention. Mean age of the patients was 60.9 +/- 12.4 years, and their mean disease duration 10.9 +/- 9.2 years. The patients remained on steroids, methotrexate, and tacrolimus as before, but were taken off any other drugs they had been using prior to the treatment. Mean of the 28-joint disease activity score using erythrocyte sedimentation rate was 4.75 +/- 1.15 initially and fell to 2.21 +/- 0.97 after two doses (n = 50). After four doses, the remission rate was 83.8% (31/37). All patients responded well to the therapy and there was no decrease in the efficacy of tocilizumab during the treatment. Even in the real clinical setting, treatment with tocilizumab can rapidly induce remission in RA in a high proportion of patients and is generally safe and well tolerated. Tocilizumab would seem to be promising as a first-line choice for the treatment of RA.
19994686 [Observation on therapeutic effect of muscular needling combined with scarring moxibustion 2009 Nov OBJECTIVE: To observe the therapeutic effect of muscular needling combined with scarring moxibustion on active stage of rheumatoid arthritis (RA). METHODS: Sixty cases of RA were randomly divided into a muscular needling group and a medication group, 30 cases in each group. The muscular needling group was treated by muscular needling on Quchi (LI 11), Sanyinjiao (SP 6), etc. combined with scarring moxibustion on Dazhui (GV 14), Zusanli (ST 36) etc., while the medication group was treated by oral administration of Diclofenac sodium and intramuscular injection of Methotrexate. The therapeutic effects, main symptoms and signs, erythrocyte sedimentation rate (ESR) and rheumatoid factor were observed in two groups before and after treatment. RESULTS: The total effective rate of muscular needling group was 76.7%, and that of medication group was 73.3%, there was no significant difference between two groups (P > 0.05). The clinical symptoms, signs, and E8R of two groups were improved obviously compared with those before treatment (P < 0.01, P < 0.05), however there were no significant differences between the two groups after treatment (all P > 0.05). The adverse reactions of medication group were more eminent compared to the muscular needling group. CONCLUSION: Muscular needling can obviously relieve the symptoms and signs of active stage rheumatoid arthritis and the effect is equivalent to oral administration of western medicine, the incidence of adverse reactions in the muscular needling group is obviously lower than that of western medication. Muscular needling is a safe and effective method for treatment of RA.
21125279 Eruptive molluscum contagiosums in a patient with rheumatoid arthritis and lung cancer. 2011 Aug A 67-year-old woman with rheumatoid arthritis (RA) treated with systemic prednisolone and methotrexate over 20 years developed eruptive molluscum contagiosums on the trunk and extremities. Investigation revealed lung cancer 2 years later. Newly development of molluscum contagiosums ceased after the surgical operation of lung cancer. Immunologic dysfunctions have been shown in RA, and especially patients under long-term methotrexate therapy are susceptible to miscellaneous skin conditions. Eruptive molluscum contagiosums are induced in association with hematologic malignancies such as lymphoma, leukemia, and HIV infection; however, it is important to investigate internal malignancies, not only hematologic malignancies but also solid cancers, when patients with RA under immunosuppressive therapies presented eruptive or disseminated molluscum contagiosums.
19371393 Treatment-induced stable, moderate reduction in blood cell counts correlate to disease con 2009 May BACKGROUND: Treatment of rheumatoid arthritis (RA) has become more intensive, thereby raising concerns regarding toxicities, including leucopenia. The objective was to analyse cell counts obtained as routine surveillance for adverse effects to assess the effect of intensive treatment and treatment dosage and to examine correlations to disease activity scores. METHODS: Patients with early RA were treated with combinations of disease-modifying anti-inflammatory drugs according to pre-defined rules, with dose adjustments contingent on residual disease activity and tolerance. RESULTS: Mean leucocyte, neutrophil and platelet counts fell with levels that correlated to disease activity scores. The strongest correlation was between platelets and disease activity scores. There was a modest, inverse correlation between methotrexate dose and monocyte and lymphocyte counts. No serious toxicity associated with the therapy was seen. CONCLUSION: Moderate reductions in cell counts are well tolerated in RA and appear to contribute to disease control.
19333678 Associations between methotrexate treatment and methylenetetrahydrofolate reductase gene p 2009 Several case reports have described associations between pathological nonvertebral fractures and low-dose methotrexate (MTX) in rheumatoid arthritis (RA) patients. Furthermore, a significant association between the C677T polymorphism in the methylenetetrahydrofolate reductase (MTHFR) gene and incident fractures has been reported in postmenopausal women. We attempted to determine whether MTX use and MTHFR polymorphisms are associated with incident fracture risk in Japanese female RA patients. DNA samples, laboratory data, and clinical data were obtained from 731 female RA patients more than 50 years old as part of the Institute of Rheumatology Rheumatoid Arthritis (IORRA) observational cohort study. Genotyping of the MTHFR polymorphisms C677T and A1298C was performed using TaqMan SNP Genotyping Assays. MTX use, MTHFR polymorphisms, and other potential risk factors predictive of fracture were analyzed by Cox proportional hazards regression models, including time-dependent covariates. During 78 months from October 2000 to March 2007, 25 and 90 patients developed vertebral and nonvertebral fractures, respectively. Patients with nonvertebral fractures were more likely to take MTX (P = 0.011; odds ratio, 1.77; 95% confidence interval, 1.13-2.76) compared to patients without fractures. Although the C677T and A1298C polymorphisms were not significantly associated with incident fracture risk, MTX use, age, disease duration, and Japanese health assessment questionnaire score were significantly (P < 0.05) and independently associated with nonvertebral fracture incidence. Our results suggest that MTX use is associated with a nonvertebral fracture risk, whereas MTHFR polymorphism status does not appear to be a clinically useful marker for predicting fracture risk in Japanese female RA patients.
20403067 Disease-modifying anti-rheumatic drug usage, prescribing patterns and disease activity in 2011 Jun AIMS: Our aim was to examine the spectrum of disease activity and usage of disease-modifying anti-rheumatic drugs (DMARD) in rheumatoid arthritis (RA) patients seen over a period of 12 months in community-based rheumatology practice. METHODS: Data were prospectively collected on 1059 consecutive RA patients who attended two private, community-based rheumatology clinics from 1 May 2007 to 1 May 2008. Information on patient demographics, medication history and disease activity was collected. Life table graphs were developed to track medication retention over time. Statistical significance was determined by log-rank tests. RESULTS: One thousand and fifty-nine patients with RA were entered into the database over a 12-month period. Eight hundred and twenty-six patients (85%) were treated with single or combination conventional DMARD compared with 159 patients (15%) on a biologic DMARD either alone or in combination. Methotrexate monotherapy was the most commonly prescribed DMARD, used in 41% of patients studied. Almost half (47%) were on combination DMARD therapy. Methotrexate and tumour necrosis factor inhibitors had the highest retention rate over 12 and 30 months since first prescription. A large proportion of patients (47%) had moderate disease activity. CONCLUSION: Rates of biologic DMARD usage were similar to other studies and the predominance of methotrexate use was also in keeping with current recommendations for management of RA. There appears to be a significant unmet need for improved disease control among RA patients with moderate disease activity, which requires further investigation.
20699242 The 2010 American College of Rheumatology/European League Against Rheumatism classificatio 2010 Sep OBJECTIVE: To apply a data-driven approach to investigate, in patients newly presenting with undifferentiated inflammatory synovitis, key variables that discriminate the subset of patients at sufficiently high risk of persistent or erosive disease for the purpose of developing new criteria for rheumatoid arthritis (RA). METHODS: In this first phase of the collaborative effort of the American College of Rheumatology and European League Against Rheumatism to develop new criteria for RA, a pooled analysis of early arthritis cohorts made available by the respective investigators is presented. All the variables associated with the gold standard of treatment with methotrexate during the first year after enrolment were first identified. Principal component analysis was then used to identify among the significant variables those sets that represent similar domains. In a final step, from each domain one representative variable was extracted, all of which were then tested for their independent effects in a multivariate regression model. From the OR in that final model, the relative weight of each variable was estimated. RESULTS: The final domains and variables identified by this process (and their relative weights) were: swelling of a metacarpophalangeal joint (MCP; 1.5), swelling of a proximal interphalangeal joint (PIP; 1.5), swelling of the wrist (1.5), tenderness of the hand (ie, MCP, PIP or wrist (2)), acute phase reaction (ie, C reactive protein or erythrocyte sedimentation rate and weights for moderate or high elevations of either one (1 for moderate, 2 for high elevation)) and serological abnormalities (ie, rheumatoid factors or anti-citrullinated protein antibodies, again with separate weights for moderate or high elevations (2 and 4, respectively)). CONCLUSION: The results of this first phase were subsequently used in the second phase of the project, which is reported in a separate methodological paper, and for derivation of the final set of criteria.
19718981 [Surgery of the wrist and hand in rheumatoid arthritis]. 2009 Jan Wrist and hand surgery in rheumatoid arthritis has continued to evolve since first being tried fifty years ago. Improvements have flowed from a better understanding of pathophysiological mechanisms, from technical progress and from more effective medical treatment. The use of methotrexate and the subsequent development of biological therapies have transformed the course of the disease, increasing the chances of positive and durable surgical results. Priority must be given to re-alignment of the wrist in order to protect the fingers. It is equally important to perform synovectomies of the extrinsic tendons and to re-align extensor tendons with the metacarpophalangeal joints. At a later stage, metacarpophalangeal arthroplasty can re-establish a useful range of mobility in these joints. Early correction of swan-neck deformity is essential. Arthrodesis of the metacarpophalangeal joint of the thumb is also beneficial as it improves finger-thumb pinch grip. These procedures are usually performed under regional block anaesthesia. They take less than two hours and the techniques employed are compatible with early mobilisation. Effective surgical management of rheumatoid arthritis requires close collaboration between surgeons, rheumatologists, physiotherapists, orthotists and occupational therapists. There are thought to be some 500,000 patients in France who might benefit from such treatment but, as yet, there are too few multidisciplinary teams equipped to manage them effectively.
19851770 Anaplastic large cell lymphoma in a patient with rheumatoid arthritis. 2011 Apr It is known that patients with rheumatoid arthritis (RA) have an increased risk for non-Hodgkin's lymphomas in comparison with the general population. Although increased risk of lymphoma is attributed to the disease activity, the drugs used in the therapy of RA may also cause increased risk of malignancy. Herein, we report on an RA patient who developed non-Hodgkin's lymphoma after methotrexate therapy and review the literature about it. A 74-year-old man with RA had been treated with low-dose methotrexate and subsequently developed anaplastic large cell lymphoma of the T-cell phenotype. Anaplastic large cell lymphoma has been reported rarely in rheumatoid arthritis.
20506371 Validity of the disease activity score in undifferentiated arthritis. 2010 Oct OBJECTIVE: To study whether the Disease Activity Score (DAS) is a valid measure of disease activity in undifferentiated arthritis (UA). METHODS: Data from a randomized, double-blind, placebo-controlled trial of methotrexate (MTX) and placebo involving 110 patients with UA were used. Data included baseline and 3, 6, 9, and 12 months, as well as diagnosis at 18 months. Validity of the DAS was analyzed using factor analysis, correlations with disease activity variables, correlations with changes in disability and joint damage, differences in DAS between diagnoses, and detecting the difference between placebo and MTX. RESULTS: Three disease activity factors were retrieved from the disease activity variables: patient reported outcomes, tender and swollen joints, and acute phase reactants. The DAS had its highest correlations (r > 0.77) with tender joint counts, followed by swollen joint counts (r > 0.63) and patient reported outcomes (r > 0.30), but the DAS correlated less with C-reactive protein levels (r = 0.32). Over time, the DAS was related to the Health Assessment Questionnaire response with an odds ratio of 4.1 (95% confidence interval 2.1-8.0), but not with change in joint damage. At 18 months, the mean DAS was 2.6 for rheumatoid arthritis patients, 2.2 for UA patients, and 1.9 for patients in remission (P = 0.001). The DAS discriminated better than all single variables between MTX and placebo, with a Guyatt's effect size of 0.89. CONCLUSION: The DAS appears to be a reasonably valid measure of disease activity for use in UA clinical trials.
19888506 Infliximab treatment in a case of rheumatoid scleromalacia perforans. 2009 Jul Ocular rheumatoid disease manifests as hyperemia of the conjunctiva and episclera, and in severe cases, episcleritis can result in nodular sclerotic and scleromalacia perforans. A clinical case of scleromalacia perforans in a 56-year-old woman with 20 years of seropositive rheumatoid arthritis of functional class IV is presented here. During that period, she received exclusively non-steroidal anti-inflammatory drugs (NSAIDs). She developed acute episcleritis of the left ocular globe, which rapidly progressed to scleromalacia perforans. Since the left eye became perforated, it was surgically enucleated, and the patient was maintained with steroidal therapy. Nevertheless, two months later she developed new-onset episcleritis of the right eye followed by scleromalacia. She was first evaluated by a rheumatologist and treated with 200 mg/dose of infliximab, which was administered monthly for the following four months. The biological treatment was accompanied by methotrexate and prednisone. With this therapy, the ocular lesion dramatically improved, and complete remission of rheumatoid arthritis and scleritis was archived four months later. In conclusion, tumour necrosis factor (TNF) blockers are effective therapeutic agents in ocular complications of rheumatoid arthritis.
20692379 Cardiac involvement in systemic rheumatic diseases: An update. 2010 Oct The high rates of cardiovascular (CV) mortality and morbidity observed in patients with systemic autoimmune diseases (SADs) cannot be fully explained by traditional atherosclerosis risk factors as standard therapy (i.e. corticosteroids and methotrexate), cytokines and disease activity may all contribute to accelerated atherosclerosis. There is considerable evidence showing that chronic inflammation and immune dysregulation play a pathogenetic role in the development of atherosclerosis in patients with SADs. Chronic inflammation, accelerated atherosclerosis and functional abnormalities of the endothelium suggest that subclinical CV involvement begins soon after the onset of the disease and progresses with disease duration. All cardiac structures may be affected during the course of SADs (valves, the conduction system, the myocardium, endocardium and pericardium, and coronary arteries), and the cardiac complications have a variety of clinical manifestations. As these are all associated with an unfavourable prognosis, it is essential to detect subclinical cardiac involvement in asymptomatic SAD patients, and begin adequate management and treatment early.
19156864 Immunoadsorption with tryptophan columns: a therapeutic option for the treatment of rheuma 2009 Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease affecting multiple organs and tissues. Although there is a wide range of therapeutic applications, the coexistence of severe side effects and contraindications outlines the necessity of new therapeutic options in the treatment of severe RA. We report on the case of a 71-year-old patient with successful treatment of a complicated RA with tryptophan immunoadsorption combined with low-dose steroids. Bacterial spondylitis developed in this patient during long-term treatment with infliximab and methotrexate. Weekly immunoadsorption sessions with tryptophan columns resulted in continuous suppression of RA activity over a period of more than 5 months, as indicated by laboratory findings, the disease activity score, and the visual analog scale. This is the first report of successful treatment of a refractory and complicated RA using tryptophan immunoadsorption columns. In conclusion, immunoadsorption is a safe and effective therapeutic alternative, which should be considered to bridge infectious complications in patients with severe RA.
20229259 Excellent therapeutic effect of tocilizumab on intestinal amyloid a deposition secondary t 2010 Oct A 64-year-old woman suffering from progressive amyloid A (AA) amyloidosis of the gastrointestinal (GI) tract, associated with active rheumatoid arthritis, was transferred to our hospital due to hypovolemic shock. Although intensive care, including treatment with prednisolone and methotrexate, improved the hypovolemic shock, paralytic ileus became dominant instead of the marked diarrhea, suggesting the terminal stage of AA amyloidosis of the GI tract. Thus, we administered tocilizumab, a humanized anti-interleukin 6 receptor antibody (8 mg/kg, repeated every 4 weeks). Two weeks after the first injection of tocilizumab, serum AA rapidly returned to their normal ranges in accordance with the amelioration of paralytic ileus and systemic joint pain. Surprisingly, after three courses of tocilizumab treatment, colon biopsy revealed no amyloid deposition. Tocilizumab is a promising agent to treat secondary AA amyloidosis by strongly suppressing serum AA levels.
19365267 Recent concepts in the inhibition of radiographic progression with biologics. 2009 May PURPOSE OF REVIEW: To provide an update on new concepts in the inhibition of radiographic progression with current and emerging biologic therapy. RECENT FINDINGS: The advent of biologic therapies for the treatment of rheumatoid arthritis has given rise to the concept of a disconnect between clinical and radiographic outcomes. Radiographic progression has been observed in patients in clinical remission, whereas inhibition of radiographic progression has been demonstrated in patients with clinically active disease. Moreover, imaging remission has been shown to be much easier to achieve than clinical remission. Biologics are superior to methotrexate (MTX) in inhibiting radiographic progression at every level of disease activity and response. The majority of patients receiving biologics and a significant proportion receiving MTX alone do not progress radiographically. The combination of a biologic and MTX inhibits radiographic progression more than either alone, reducing both the proportion of patients progressing and the degree of progression of those who do progress. Although biologics are similar in their ability to inhibit radiographic progression in most patients, they differ in inhibiting the progression in the rapid radiographic progressors. SUMMARY: The disconnect between clinical and radiographic outcomes demonstrated with biologics implies the need to monitor both outcomes in order to treat patients most effectively. The superiority of biologics over MTX in inhibiting radiographic progression suggests that the clinical target for a biologic may differ from that for MTX to prevent structural damage and preserve function. For most patients, radiographic inhibition should not affect the choice of a biologic.
