Cycling versus swapping strategies in psoriatic arthritis: results from the rheumatic diseases Portuguese register.

OBJECTIVE: To compare the 2-year retention rate between a second tumor necrosis factor alpha inhibitor (TNFi) and secukinumab (SEK) or ustekinumab (UST), in Psoriatic Arthritis (PsA) patients with previous inadequate response to their first TNFi. METHODS: Prospective longitudinal cohort study with a follow-up period of 2 years using the Nationwide Portuguese Reuma.pt database. Patients with a clinical diagnosis of PsA who also fulfill the CASPAR classification criteria, with previous treatment failure to a first-line TNFi and having started a second biotechnological drug (TNFi, SEK or UST) were included. The Cycling group was defined as switching from a first TNFi to a second TNFi, and the Swapping group as switching from a first TNFi to SEK or UST. Sociodemographic data, disease characteristics, disease activity scores and physical function at baseline and after 6, 12 and 24 months were recorded. Cox-proportional hazards regression was used to compare retention rates between Cycling and Swapping groups. To obtain a predictor model of 2-year discontinuation, a multivariable Cox regression model was performed. RESULTS: In total, 439 patients were included, 58% were female, with a mean age (standard deviation) of 49 (12) years. Globally, 75.6% initiated a second TNFi (Cycling group), and 24.4% started SEK/UST (Swapping group). The retention rates after 6, 12 and 24 months were 72%/66%/59% in the Cycling group; and 77%/66%/59% in the Swapping group. There were no significant differences in retention rates between both strategies (HR: 1.06, 95% CI 0.72-1.16). After 2 years of follow-up, 34.4% of patients discontinued their second biologic, mainly due to inefficacy (72.8%), with no differences found between groups. Baseline treatment with glucocorticoids was the only predictor of discontinuation after 2 years of follow-up (HR:1.668, 95% CI 1.154-2.409). CONCLUSIONS: After failure of a first TNF inhibitor, Cycling and Swapping strategies result in similar retention rates suggesting that both are acceptable in the management of patients with psoriatic arthritis.

A multidisciplinary approach in psoriatic disease: the different models of dermatology-rheumatology collaborations in Portugal.

Psoriatic disease (Psoriasis and Psoriatic Arthritis, PsD) is a condition that affects the skin, the musculoskeletal system, and beyond, impairing patients' quality of life. A multidisciplinary approach of combined dermatology-rheumatology clinics is recommended and valuable to respond to PsD diagnosis, management, and treatment challenges. In Portugal, five Hospitals have implemented a multidisciplinary clinic for PsD assessment. This report aims to describe how these multidisciplinary clinics were developed, their characteristics, and the main obstacles to their implementation. Although the different hospitals adopted distinct functional models, a consensus respecting the minimal core set assessment for PsD in Multidisciplinary Dermatology/Rheumatology Clinics should comprise all disease manifestations and, if possible, quality of life. The main objective of these clinics is to achieve remission/minimal disease activity. Limitations to these multidisciplinary approaches are discussed, namely financial, time management, and human resources obstacles that can be a handicap in their implementation, despite the benefits of PsD integrated care.

Rheuma SPACE - Standard Practice Aiming Clinical Excellence: the first Portuguese Rheumatology Department evaluation.

The Portuguese Rheumatology Society (SPR) embraced quality as a major goal and launched, in early 2015, a program to aim for excellence in global clinical care: Rheuma SPACE - Standard Practice Aiming Clinical Excellence. Evaluating daily reality is the first step in a quality development timeline, ultimately contributing for health gains. Herein we describe the results of the evaluation of the quality indicators defined for this project and the improvement strategies identified. The Rheuma SPACE project included three phases: 1) establishing a set of quality indicators and an excellence quality model; 2) assessment of the current care at Rheumatology departments concerning the defined quality indicators in the scope of the excellence model; and 3) elaboration of global and customized reports for each participating Rheumatology department, resulting in the identification of improvement opportunities. Ten Rheumatology departments, countrywide, including larger and smaller institutions, were asked to participate in Rheuma SPACE. This resulted in an individual report for each department along with global benchmarking practices analysis. Furthermore, a list of improvement initiatives was developed. We concluded that departments lack physicians and need exclusively dedicated nurses. Time dedicated to research and audit activities should be specifically allocated. Internal contracting is well established, and professionals are committed to targets. Processes are still suboptimal, needing standardization of triage criteria, more frequent follow-up, as well as better medical records and multidisciplinary coverage. Regarding outcomes, patients are satisfied with the provided care and professionals with the working environment. However, department facilities for the former, and career related aspects, for the latter should improve. With this innovative study conducted in Portugal we expect to have enlightened tailored opportunities for improvement, ensure patient-focused practices and be able to define the indispensable quality requirements for excellence.

Real-world Longterm Effectiveness of Tumor Necrosis Factor Inhibitors in Psoriatic Arthritis Patients from the Rheumatic Diseases Portuguese Register.

OBJECTIVE: To assess longterm effectiveness of tumor necrosis factor inhibitors (TNFi) in patients with psoriatic arthritis (PsA) registered in the Rheumatic Diseases Portuguese Register, exposed to at least 1 TNFi, prospectively followed between 2001 and 2017. METHODS: Kaplan-Meier analysis was performed for first-, second-, and third-line TNFi. Responses included European League Against Rheumatism (EULAR) criteria, Disease Activity Index for Psoriatic Arthritis (DAPSA), minimal disease activity (MDA), and Ankylosing Spondylitis Disease Activity Score (ASDAS) at 3 and 6 months. Baseline predictors of discontinuation and response were studied using Cox and multivariable multinomial/logistic regression models. RESULTS: The 750 patients with PsA showed drug retention of 4.1 ± 3.4 years (followup 5.8 ± 3.8 yrs) for first TNFi. Switching to a second (189 patients) or third (50 patients) TNFi further decreased survival by 1.1 years. Female sex, higher baseline 28-joint count Disease Activity Score, and infliximab were predictors of first TNFi discontinuation. After 6 months of the first TNFi, 48.7% of patients achieved a good EULAR criteria response and 20.9% were in DAPSA remission. There were 11.4% in MDA, and 56.4% had a good ASDAS. Responses to the second TNFi were significantly inferior compared to responses to the first TNFi. Female sex and higher baseline Health Assessment Questionnaire-Disability Index were negatively associated with good EULAR response at 3 months, and obesity decreased the chance of response at 6 months. CONCLUSION: In this study, switching to a second or third TNFi was associated with significantly lower drug survival and response rates for patients with axial and peripheral PsA subtypes. More successful therapeutic approaches will require considering the effect of sex and obesity on TNFi effectiveness.

Rheuma SPACE - Standard Practice Aiming Clinical Excellence: description of the methodological approach.

BACKGROUND: Quality of care is a key component of the right to health, and the route to equity and dignity. The aim of the project Rheuma SPACE - Standard Practice Aiming Clinical Excellence was to develop a set of quality indicators focused in rheumatoid arthritis care and apply them to rheumatology departments of the Portuguese National Health Service in order to benchmark the care for these patients. This article details the methodology that was applied. METHODOLOGY: This was a single country, three-phase project, each phase comprising multiple steps. The first step defined quality indicators and the excellence quality model to be used. It involved a literature search for international benchmarking of quality of care initiatives and indicators, followed by a pre-selection of an initial set of indicators. The set of indicators was latter on narrowed after an online Delphi round with all Portuguese rheumatologists and two consensus meetings involving the study task force. A set of 26 quality indicators was defined, within the three classic Donabedian dimensions of healthcare quality: Structure (9), Processes (11), and Outcomes (6). These indicators cover eleven domains of quality of care: personnel and organizational structure, training and research, facilities, equipment and information technology, budgeting and financial resources, access to care, clinical records, patient communication, multidisciplinary management, clinical outcomes, and patient and personnel satisfaction. Decision on quality and excellence thresholds for each of the 26 quality indicators was agreed upon a consensus meeting gathering principal investigators of the eight Rheumatology Departments that decided to participate, task force core set members and invited representatives of all Portuguese Departments/Units. Rheumatoid arthritis was the chosen disease model of the project based on the reliability of the outcomes to be measured in the context of this condition. The second step was the assessment of the participating Rheumatology Departments. During eighteen months, research teams applied the 26 quality indicators to their own Departments. The third step comprised data analysis and the elaboration of individual Rheumatology Department reports and of a global public report. RESULTS: Eight Departments, comprising 80 specialists, 20 residents and 30 nurses, covering 5.904.080 inhabitants, underwent quality evaluation. More than one thousand patients (1,325) and 113 health professionals' surveys were analysed, as well as data from 570 clinical records and 3,927 medical appointments on rheumatoid arthritis patients. DISCUSSION: 26 quality indicators were used for the first evaluation of Portuguese Rheumatology Departments, turning Rheuma SPACE into a pioneer project. Data analysis and benchmarking will be the subject of a further publication.

Predictors of response to TNF blockers in patients with polyarticular psoriatic arthritis.

Psoriatic arthritis (PsA) is a chronic inflammatory rheumatic disease with a broad clinical spectrum. PsA can affect the axial skeleton, peripheral joints, entheses, synovial sheaths of tendons, skin, nails and extra-articular organs. Tumour necrosis factor alpha blockers (TNF blockers) were a breakthrough development in the treatment of PsA. Identifying predictors of response to biological therapies in patients with PsA is of utmost importance, especially in view of the costs and potential side effects of these agents. The aims of the present study were to determine baseline predictive factors of response to biological therapies, at 3 and 6 months, in PsA patients with polyarticular involvement (with or without axial involvement). Data were collected from the Rheumatic Diseases Portuguese Register (Reuma.pt). Eligible patients had to be anti-TNF-naive at baseline and to have at least 3 months of follow-up after the beginning of TNF blocker therapy. Only patients with information on at least one of the response measures (at 3 or 6 months of follow-up) were included in the analysis. Univariable logistic regression analysis of potential baseline predictors of European League Against Rheumatism (EULAR) good clinical response, EULAR good/moderate response, 28-joint Disease Activity Score with three variables including the erythrocyte sedimentation rate (DAS28-3V-ESR) remission and Health Assessment Questionnaire (HAQ) response were performed. Multivariable logistic regression using a forward selection procedure was used until the best-fit model was obtained, taking confounding effects into account. A total of 180 patients were eligible for the study (mean age 52 years, 54% women). In multivariable analysis at 3 months, females were less likely to attain a good EULAR response [OR=0.082 (95% CI=0.024, 0.278)], a DAS28-3V-ESR remission [OR=0.083 (95% CI=0.017, 0.416)], a moderate or good EULAR response [OR=0.091 (95% CI=0.011, 0.091)] and a HAQ response [OR=0.074 (95% CI=0.009, 0.608)]. At 6 months, female gender was also less likely to achieve a good EULAR response [OR=0.060 (95% CI=0.011, 0.325)], DAS28-3V-ESR remission [OR=0.060 (95% CI=0.012, 0.297)], and a HAQ response [OR=0.138 (95% CI= 0.029, 0.654)]. In this study we found that gender was the most consistent predictor of response to TNF blocker therapy in patients with polyarticular PsA, with females having a lower probability of response compared to males. These findings suggest that gender-related biochemical, hormonal and psychological factors could play an important role in the response to TNF blocker therapy in PsA.

Effectiveness of early adalimumab therapy in psoriatic arthritis patients from Reuma.pt - EARLY PsA.

Objective To compare outcomes in psoriatic arthritis (PsA) patients initiating adalimumab (ADA), with short- and long-term disease duration and to evaluate the potential effect of concomitant conventional synthetic disease-modifying antirheumatic drugs (csDMARD) or glucocorticoids. Methods Analyses included adult PsA patients registered in the Rheumatic Diseases Portuguese Register (Reuma.pt) between June 2008-June 2016 who received ADA for ≥3 months. Psoriatic Arthritis Response Criteria (PsARC) response, tender and swollen joint count, inflammatory parameters, patient (PtGA) and physician global assessment (PhGA), Disease Activity Score-28 joints (DAS28), and Health Assessment Questionnaire Disability Index (HAQ-DI) were compared between patients with <5 years of disease (early PsA) and those with ≥5 years of disease duration (late PsA). Time to achieving PsARC response was estimated using the Kaplan-Meier method. Results Of 135 PsA patients treated with ADA, 126 had information on disease duration (earlyPsA, n=41). PsARC response was achieved by 72.9% of the patients (88.0% early PsA vs 62.2% late PsA; P=0.022) after 3 months and by 85.4% after 24 months (100% early PsA vs 75.9% late PsA; P=0.044). Early PsA patients achieved significantly less painful joints (2.7 vs 6.7, p=0.006), lower mean C-reactive protein (0.5 mg/dL vs 1.3 mg/dL; P=0.011), and PhGA (18.3 vs 28.1; P=0.020) at 3 months. In the long term, early PsA patients also had fewer swollen joints (0.3 vs 1.7; P=0.030) and lower PhGA (6.3 vs 21.9; P<0.001), C-reactive protein (0.4 mg/dL vs 1.0 mg/dL; P=0.026), and DAS28 (2.2 vs 3.2; P=0.030). HAQ-DI decreased in both groups reaching a mean value at 24 months of 0.4 and 0.8 (P=ns) in early and late PsA, respectively. Early PsA patients obtained PsARC response more rapidly than late PsA (3.8 and 7.4 months, respectively; P=0.008). Concomitant csDMARDs showed clinical benefit (2-year PsARC response, 88.3% vs 60.0%; P=0.044). Concomitant glucocorticoids had no effect on PsARC response over 2 years of follow-up. Persistence on ADA was similar in both groups. Conclusion Early PsA patients had a greater chance of improvement after ADA therapy and better functional outcome, and achieved PsARC response more rapidly than late PsA. In this cohort, comedication with csDMARDs was beneficial over 2 years.

Utilization of Subcutaneous Methotrexate in Rheumatoid Arthritis Patients After Failure or Intolerance to Oral Methotrexate: A Multicenter Cohort Study.

INTRODUCTION: Low-dose weekly methotrexate (MTX) is the mainstay in the therapy of rheumatoid arthritis (RA). It can be given via oral, intramuscular or subcutaneous (SC) route. This study sought to determine the real-world pattern of treatment with SC MTX in Portuguese adult patients with active RA. METHODS: Utilization of Metoject(®) in Rheumatoid Arthritis (UMAR) was a non-interventional, cohort multicenter study with retrospective data collection. Eligible patients had active RA, at least 18 years of age, and started SC MTX treatment in 2009 or 2010 after failure or intolerance to oral MTX. Data were collected from patient's clinical records. Both non-parametric and parametric survival methods were used to obtain a detailed understanding of SC MTX treatment duration. RESULT: Fifty patients were included, of which only 9 discontinued SC MTX during the study follow-up period. The probability of discontinuation after 1, 2, and 3 years of treatment of SC MTX treatment is expected to be 6.10%, 8.50%, and 23.20%, respectively. The extrapolated median duration of SC MTX using an exponential model was 106.4 months/8.87 years. Mean dose of SC MTX was 18.36 mg. The reasons for treatment discontinuation were occurrence of adverse events in six patients and lack of efficacy in three. CONCLUSION: The long treatment duration of SC MTX highlights its excellent tolerability compared to oral MTX, especially concerning the frequent adverse gastrointestinal events of MTX. Furthermore, long MTX treatment duration provides the opportunity to postpone or even avoid expensive therapies with biologics. The results obtained from the UMAR study provide important information for the utilization and public financing of SC MTX in Portugal.

Comparative Effectiveness of Tocilizumab and TNF Inhibitors in Rheumatoid Arthritis Patients: Data from the Rheumatic Diseases Portuguese Register, Reuma.pt.

OBJECTIVES: To compare the effectiveness of TNF inhibitors (TNFi) and tocilizumab in rheumatoid arthritis (RA) treatment, according to different response criteria. METHODS: We included RA patients registered in the Rheumatic Diseases Portuguese Register treated with TNFi or tocilizumab for at least 6 months, between January 2008 and July 2013. We assessed remission/low disease activity (LDA) at 6 months according to DAS28, CDAI, and SDAI, as well as Boolean ACR/EULAR remission and EULAR response rate, adjusting for measured confounders. RESULTS: Tocilizumab-treated patients (n = 95) presented higher baseline disease activity and were less frequently naïve to biologics compared to TNFi users (n = 429). Multivariate logistic regression analysis including the propensity score for receiving tocilizumab showed that patients treated with tocilizumab were more likely to achieve remission or LDA according to DAS28 (OR = 11.0/6.2, 95% CI 5.6-21.6/3.2-12.0), CDAI (OR = 2.8/2.6, 95% CI 1.2-6.5/1.3-5.5), or SDAI (OR = 3.6/2.5, 95% CI 1.5-8.7/1.1-5.5), as well as a good EULAR response (OR = 6.4, 95% CI 3.4-12.0). However, both groups did not differ in Boolean remission (OR = 1.9, 95% CI 0.8-4.8) or good/moderate EULAR response (OR = 1.8, 95% CI 0.8-4.5). CONCLUSIONS: Compared with TNFi, tocilizumab was associated with greater likelihood of achieving DAS28, CDAI, and SDAI remission/LDA and EULAR good response. Boolean remission and EULAR good/moderate response did not differ significantly between groups.

Classification of Systemic Lupus Erythematosus: Systemic Lupus International Collaborating Clinics Versus American College of Rheumatology Criteria. A Comparative Study of 2,055 Patients From a Real-Life, International Systemic Lupus Erythematosus Cohort.

OBJECTIVE: The new Systemic Lupus International Collaborating Clinics (SLICC) 2012 classification criteria aimed to improve the performance of systemic lupus erythematosus (SLE) classification over the American College of Rheumatology (ACR) 1997 criteria. However, the SLICC 2012 criteria need further external validation. Our objective was to compare the sensitivity for SLE classification between the ACR 1997 and the SLICC 2012 criteria sets in a real-life, multicenter, international SLE population. METHODS: We conducted a cross-sectional observational study of patients with a clinical diagnosis of SLE followed at the participating rheumatology centers and registered in the Portuguese and Spanish national registries. The sensitivity of the 2 classification sets was compared using McNemar's test. The sensitivity of ACR 1997 and SLICC 2012 was further examined in 5 subgroups, defined according to disease duration. RESULTS: We included 2,055 SLE patients (female 91.4%, white 93.5%, mean ± SD age at disease onset 33.1 ± 14.4 years, mean ± SD age at SLE diagnosis 35.3 ± 14.7 years, and mean ± SD age at the time of the study 47.4 ± 14.6 years) from 17 centers. The sensitivity for SLE classification was higher with the SLICC 2012 than with the ACR 1997 (93.2% versus 85.6%; P < 0.0001). Of 296 patients not fulfilling the ACR 1997, 62.8% could be classified with the SLICC 2012. The subgroup of patients with ≤5 years since disease onset presented the largest difference in sensitivity between the SLICC 2012 and the ACR 1997 (89.3% versus 76.0%; P < 0.0001); this difference diminished with longer disease duration, and it was no longer significant for patients with >20 years of disease duration. CONCLUSION: The SLICC 2012 criteria were more sensitive than the ACR 1997 criteria in real-life clinical practice in SLE. The SLICC 2012 criteria may allow patients to be classified as having SLE earlier in the disease course.

Cervical spine involvement as initial manifestation of rheumatoid arthritis: a case report.

Rheumatoid arthritis' synovitis affects mostly small hand and feet joints, although it may compromise any joint with a synovial lining. Cervical involvement occurs usually in longstanding disease in over half of these patients. We report the case of a 35-year old male patient who was referred to our outpatient clinic for a 2-year severe and disabling inflammatory neck pain, with incomplete response to intramuscular non-steroidal anti-inflammatory drugs and unremarkable cervical imaging studies. He also mentioned self-limited episodes of symmetric polyarthralgia involving hands, wrists, elbows, knees and feet, which started after his cervical complaints. On laboratorial workup, positive rheumatoid factor and anti-citrullinated peptide antibody and negative HLA-B27 were found. Cervical spine magnetic resonance imaging revealed atlantoaxial subluxation and odontoid process inflammatory pannus and erosions. Rheumatoid arthritis with cervical spine involvement as initial manifestation of disease was the definite diagnosis. The patient was started on methotrexate and prednisone and he was referred to neurosurgery outpatient clinic for cervical spine fixation.

Off-label use of rituximab in systemic rheumatic diseases: case series and review.

B-cells play an important role not only in cellular but also in humoral immunity through differentiation into plasma cells and antibody production. B-cell depletion may, theoretically, change the course of systemic rheumatic diseases (SRD) in which self-reactive antibodies are part of the pathogenic pathway. In Rheumatology, anti-B-cell antibody Rituximab is currently licensed for the treatment of rheumatoid arthritis, however there is growing evidence of its potential use in other SRD. The authors present a case series of eight patients in which Rituximab was used off-label including overlap syndrome Rhupus, systemic lupus erythematosus and Wegener's granulomatosis. In the end, a brief literature review about this subject is performed.

[Portuguese recommendations for pain management by pharmocotherapy in inflammatory arthritis]. / Recomendações portuguesas para o tratamento e controlo farmacológico da dor nas artropatias inflamatórias.

OBJECTIVES: To develop Portuguese evidence-based recommendations for pain management by pharmocotherapy in inflammatory arthritis. METHODS: The Portuguese project was integrated in the multinational 3E Initiative (Evidence, Expertise, Exchange) 2010 where a total of 453 rheumatologists from 17 countries have participated. The clinical questions concerning pain were formulated and the Portuguese group added 2 more questions. A systematic literature search was performed in Medline, Embase, Cochrane Library and 2008-2009 EULAR and ACR abstracts. The selected articles were systematically reviewed and the evidence was defined according to the Oxford Levels of Evidence. In each country a group of experts joined to discuss their national recommendations. In Portugal, the national meeting was held in October 2010, where 33 rheumatologists discussed and voted by Delphi method the national recommendations. Finally, the agreement among the rheumatologists and the potential impact on their clinical practice was assessed. RESULTS: Thirteen national recommendations were formulated: pain measure scores; analgesic combination therapy; pharmacotherapy in preconception, pregnancy and lactation periods; pharmacotherapy according to comorbilities; safety of NSAIDs and/or paracetamol with methotrexate combination therapy; efficacy and safety of continuous/on-demand NSAIDs; opioids, paracetamol, corticosteroids, antidepressants, neuromodulators and muscle relaxants role and effectiveness; risk factors for the development of chronic pain and the role of topic analgesics. CONCLUSION: The portuguese recommendations for the pain management by pharmacotherapy in inflammatory arthritis were formulated according to the best evidence and supported by a panel of 63 rheumatologists. The differences between the national and international recommendations are reported in this article.

Klebsiella pneumoniae Spinal Epidural Abscess treated conservatively: case report and review.

Spinal infections are rare but potentially life-threatening disorders. A high level of clinical suspicion is necessary for rapid diagnosis and treatment initiation. The treatment combines both antibiotics and surgical intervention in the vast majority of cases. The authors report the case of a 84-year old female patient with a three week history of persistent lumbar back pain radiating to both thighs following a lower respiratory tract infection. She had lumbar spine tenderness but no neurological compromise. Her inflammatory markers were elevated and lumbar spine magnetic resonance imaging revealed L4-L5 spondylodiscitis with spinal epidural abscess. Blood cultures isolated Klebsiella pneumoniae and, since she was neurologically stable, conservative treatment with two-week intravenous gentamicin and eight-week intravenous ceftriaxone was initiated with positive inpatient and outpatient evolution.

Predictors of damage progression in Portuguese patients with systemic lupus erythematosus.

Patients with systemic lupus erythematosus (SLE) have a longer life expectancy. The occurrence of irreversible damage has become a major concern. The present study assessed damage progression in patients with SLE over a 2-year period and identified baseline features associated with damage accrual. Two hundred and twenty-one patients that fulfilled criteria for SLE and had a follow-up longer than 6 months were enrolled. Demographic, clinical, and immunological data were collected at baseline. Accumulated organ damage was scored using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index (SDI). Patients were prospectively followed and SDI assessment repeated at 2 years. At baseline 72 patients (33%) presented some irreversible damage, and after 2 years 53 had accrued new damage. The mean SDI for the whole cohort increased from 0.582 to 0.980. Damage progression was higher in ocular, cardiovascular, and musculoskeletal systems. Older age [OR = 1.045; 95% confidence interval (CI) 1.021-1.069; P = 0.03], presence of antiphospholipid antibodies (OR = 3.047; 95% CI 1.169-7.941; P = 0.02), steroid use (OR = 6.401; 95% CI 1.601-25.210; P = 0.008), azathioprine use (OR = 3.501; CI 1.224-10.012; P = 0.01), and hypertension (OR = 3.825; 95% CI 1.490-9.820; P = 0.005) were predictors of damage progression in multivariate analysis. Overall SDI increased over time, with some systems being affected more frequently. Demographic and clinical characteristics, co-morbidity, and treatment options may contribute to irreversible damage. It is necessary to determine whether the control of modifiable factors (e.g., hypertension and judicious use of medications) might prevent damage progression in SLE patients.

[Juvenile dermatomyositis associated with anasarca - a clinical case]. / Dermatomiosite juvenil associada a anasarca - a propósito de um caso clínico.

Juvenile dermatomyositis (JDM) is a rare systemic disease of unknown etiology characterized by inflammation of the muscle, skin and digestive tract, with variable outcome. The diagnostic criteria include proximal symmetrical muscular weakness, characteristic skin rashes, elevation of skeletal muscle enzymes and specific electromyographic and muscle biopsy abnormalities. Pulmonary and gastro-intestinal involvements, calcinosis and generalized edema usually indicate severe disease. Recent data suggest an association between the genotype -308 AA of the Tumour Necrosis Factor (TNF) gene and disease chronicity. We present a case of a 14 year-old female with JDM and generalized oedema which is a rare manifestation of the disease and it is associated to a poor outcome.

[Eosinophilic fasciitis and aplastic anemia]. / Fasceíte eosinofílica e aplasia medular.

Eosinophilic fasciitis is a rare rheumatic condition characterized by inflammatory thickening of the skin and fascia, peripheral eosinophilia, elevated erythrocyte sedimentation rate and hypergammaglobulinemia. Internal organ involvement is uncommon. It is often difficult to diagnose eosinophilic fasciitis and its course may be variable. Glucocorticoids are most commonly used in the treatment but in many cases they are ineffective, requiring combined immunosuppressive treatment. Several cases of eosinophilic fasciitis and serious haematological disorders such as immune thrombocytopenia, Hodgkin's disease and aplastic anaemia have been described. The authors report an atypical severe case of eosinophilic fasciitis complicated by aplastic anaemia non responsive to treatment.

[Is the response to anti-TNFalpha treatment influenced by the presence of IgM rheumatoid factor, in Rheumatoid Arthritis patients?]. / Associação entre presença de factores reumatóides IgM no soro e resposta à terapêutica com agentes inibidores do TNFalpha em doentes com Artrite Reumatóide.

AIM: To verify if the response to TNFalpha inhibitors is influenced by the presence of IgM rheumatoid factor (RF), in patients with RA. MATERIAL AND METHODS: In this study, the patients with the diagnosis of RA treated with TNFa inhibitors followed in our hospital were recruited. A protocol was applied including demographic, clinical and laboratory data, in order to calculate DAS 28. The presence/absence of IgM RF and associated therapies were record. RESULTS: Fifty-seven patients, 52 female, with a mean duration of anti-TNFa treatment of 30,9+/-15,9 months were studied. Twenty-four patients were being treated with infliximab, 17 with adalimumab and 16 with etanercept. Forty-one patients had IgM RF detectable in serum (RF positive group). In the RF positive group, the variation of DAS 28 was -1,75 +/- 1,53 vs -1,04 +/- 1,76 in the RF negative group (p=0,135). The mean duration of anti-TNFalpha treatment was similar in both groups (31,9+/-15,9 vs 29,5+/-16,16 months). Patients who were treated with methotrexate presented a higher variation of DAS 28 (-1,87 +/- 1,70 vs -0,80 +/- 1,09; p=0,041) and this variation was dose dependent (p=0,056). CONCLUSIONS: Despite needing a replication in a larger cohort, our results suggest that the presence of IgM RF in the serum did not interfere with the response to treatment with TNFalpha inhibitors.

Contribution for new genetic markers of rheumatoid arthritis activity and severity: sequencing of the tumor necrosis factor-alpha gene promoter.

The objective of this study was to assess whether clinical measures of rheumatoid arthritis activity and severity were influenced by tumor necrosis factor-alpha (TNF-alpha) promoter genotype/haplotype markers. Each patient's disease activity was assessed by the disease activity score using 28 joint counts (DAS28) and functional capacity by the Health Assessment Questionnaire (HAQ) score. Systemic manifestations, radiological damage evaluated by the Sharp/van der Heijde (SvdH) score, disease-modifying anti-rheumatic drug use, joint surgeries, and work disability were also assessed. The promoter region of the TNF-alpha gene, between nucleotides -1,318 and +49, was sequenced using an automated platform. Five hundred fifty-four patients were evaluated and genotyped for 10 single-nucleotide polymorphism (SNP) markers, but 5 of these markers were excluded due to failure to fall within Hardy-Weinberg equilibrium or to monomorphism. Patients with more than 10 years of disease duration (DD) presented significant associations between the -857 SNP and systemic manifestations, as well as joint surgeries. Associations were also found between the -308 SNP and work disability in patients with more than 2 years of DD and radiological damage in patients with less than 10 years of DD. A borderline effect was found between the -238 SNP and HAQ score and radiological damage in patients with 2 to 10 years of DD. An association was also found between haplotypes and the SvdH score for those with more than 10 years of DD. An association was found between some TNF-alpha promoter SNPs and systemic manifestations, radiological progression, HAQ score, work disability, and joint surgeries, particularly in some classes of DD and between haplotypes and radiological progression for those with more than 10 years of DD.

[Tuberculosis in rheumatic patients treated with tumour necrosis factor alpha antagonists: the Portuguese experience]. / Tubereulose em doentes reumáticos tratados com antagonistas do factor de necrose tumoral alfa: a experiência Portuguesa.

In Portugal, 13 cases of tuberculosis (TB) were reported, in the period between 1999 and 2005, in 960 patients exposed to anti-TNFalpha treatment (1.35%), 8 females and 5 males. Mean age was 46.7 +/- 13.8 years. 9 patients had rheumatoid arthritis (RA), in 639 exposed patients (1.4%), 3 had ankylosing spondylitis (AS), in 200 exposed patients (1.5%) and 1 had psoriatic arthritis (PA), in 101 exposed patients (1%). The anti-TNFa used was in 8 cases infliximab (in 456 patients exposed, 1.5%), in 4 adalimumab (in 171 patients exposed, 2.3%) and in 1 etanercept (in 333 exposed, 0.3%). Treatment with a biological agent was started 11.1 +/- 8.7 months (min 3 and max 50) before TB onset. Tuberculin skin test (TST) was performed in 9 out of the 13 patients (the other 4 had started biological therapy before 2002). In 3 cases the TST response was 0 mm, in 3 less than 10 mm, in one was 14 mm and in two 20 mm. In the 3 cases with a TST response superior to 10 mm, isoniazid treatment 300 mg/d was prescribed, during 9 months. The time between first symptoms and TB diagnosis was 2.6 +/- 2.9 months. TB involvement was pulmonary in 6 patients, lymph node disease in 2, peritoneal and pulmonary in 2, osteoarticular in one case, lymph node disease and splenic in another and miliar TB in the last case. One death was reported; all of the other cases had a good outcome after anti-TB treatment. In two cases (one treated with adalimumab and the other with infliximab), paradoxical response to treatment occurred. None of the patients has restarted biological therapy after TB treatment.
