RESUMEN
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.

OBJECTIVE: To develop recommendations for the treatment of psoriatic arthritis (PsA) with biological therapies, endorsed by the Portuguese Society of Rheumatology. METHODS: These treatment recommendations were formulated by Portuguese rheumatologists based on literature evidence and consensus opinion. A draft of the recommendations was first circulated to all Portuguese rheumatologists and their suggestions were incorporated in the draft. At a national meeting the recommendations were discussed and all attending rheumatologists voted on the level of agreement for each recommendation. A second draft was again circulated before publication. RESULTS: A consensus was achieved regarding the initiation, assessment of response and switching biological therapies in patients with PsA. Specific recommendations were developed for several disease domains: peripheral arthritis, axial disease, enthesitis and dactylitis. CONCLUSION: These recommendations may be used for guidance in deciding which patients with PsA should be treated with biological therapies. They cover a rapidly evolving area of therapeutic intervention. As more evidence becomes available and more biological therapies are licensed, these recommendations will have to be updated.

OBJECTIVE: To develop recommendations for the treatment of axial spondyloarthritis with biological therapies, endorsed by the Portuguese Society of Rheumatology. METHODS: These treatment recommendations were formulated by Portuguese rheumatologists based on literature evidence and consensus opinion. A draft of the recommendations and supporting evidence was first circulated to all Portuguese rheumatologists and their suggestions were incorporated in the draft. Secondly, at a national meeting the recommendations were presented, discussed and revised. Finally, the document resulting from this meeting was again circulated to all Portuguese rheumatologists, who anonymously voted online on the level of agreement with the recommendations. RESULTS: A consensus was achieved regarding the initiation, assessment of response and switching biological therapies in patients with axial spondyloarthritis. CONCLUSION: These recommendations may be used for guidance in deciding which patients with axial spondyloarthritis should be treated with biological therapies. They cover a rapidly evolving area of therapeutic intervention. As more evidence becomes available and more biological therapies are licensed, these recommendations will have to be updated.

The authors present the revised version of the Portuguese Society of Rheumatology (SPR) guidelines for the treatment of Rheumatoid Arthritis (RA) with biological therapies. In these guidelines the criteria for introduction and maintenance of biological agents are discussed as well as the contraindications and procedures in the case of nonresponders. Biological treatment (with a tumour necrosis factor antagonist, abatacept or tocilizumab) should be considered in RA patients with a disease activity score 28 (DAS 28) equal to or greater than 3.2 despite treatment with at least 20mg-weekly-dose of methotrexate (MTX) for at least 3 months or, if such treatment is not possible, after 3 months of other conventional disease modifying drug or combination therapy. A DAS 28 score between 2.6 and 3.2 with a significant functional or radiological deterioration under treatment with conventional regimens could also constitute an indication for biological treatment. The treatment goal should be remission or, if that is not achievable, at least a low disease activity, defined by a DAS28 lower than 3.2, without significative functional or radiological worsening. The response criteria, at the end of the first 3 months of treatment, are a decrease of at least 0.6 in the DAS28 score. After 6 months of treatment response criteria is defined as a decrease greater than 1.2 in the DAS28 score. Non-responders, in accordance to the Rheumatologist's clinical opinion, should try a switch to another biological agent (tumour necrosis factor antagonist, abatacept, rituximab or tocilizumab).

OBJECTIVES: The aims of this study were to assess the efficacy of infliximab (IFX) combined with methotrexate (MTX) versus IFX alone in the treatment of ankylosing spondylitis (AS). METHODS: The study was a 30weeks open label and prospective study of parallel groups in 19 patients with active AS. These patients had shown incomplete therapeutic response to standard therapy (full dose of non-steroidal anti-inflammatory drugs: NSAIDs) and disease modifying antirheumatic drugs: DMARDs (MTX or sulfasalazine: SLZ) for a period of at least 12 weeks and were treated with IFX (5mg/kg). Patients were divided into two treatment groups according to the previous treatment: in Group A, 9 patients previously treated with 7.5mg/week of MTX were treated with IFX in addition to MTX (IFX+MTX); in Group B, 10 patients previously treated only with NSAIDs were treated with IFX (5mg/kg) as monotherapy (IFX). The primary outcome was improvement in disease activity shown by the BASDAI50 at week 30; the secondary outcome included comparison of the proportions of subjects in each group achieving response criteria proposed by the ASAS group. BASDAI, BASFI, ESR, CRP, pain, inflammation and Patient Global Assessment were also recorded. RESULTS: Both groups were similar in sex ratio, clinical forms and B27. Differences between groups occurred only in the disease duration and age of the patient. At 14 and 30 weeks only 50% and 10% respectively of the patients from the IFX group achieved BASDAI50 response compared to 89% of patients from the IFX+MTX group. The difference between groups at 30 weeks was statistically significant (p=0.001; percentage of difference: 79%; 95% confidence interval (CI): 26-93%:). ASAS50 was reached in 67% and 55.6% of patients from the IFX+MTX group at 14 and 30 weeks respectively, compared with 30% and 0% of patients from the IFX group The difference between groups at 30 weeks was statistically significant (p=0.011; percentage of difference: 57%; 95% CI: 8-84.7%). CONCLUSION: Infliximab in combination with MTX seems to increase the efficacy of the therapeutic response in active AS patients, but more wide-ranging studies are necessary, mainly long-term studies.

Ankylosing spondylitis (AS) is an inflammatory chronic disease that affects young males and in more than 90% of cases is associated with HLA B27 antigen. Therapeutic options for those patients with spondyloarthropathies have been limited during the last decades. Infliximab and etanercept are both approved for the treatment of patients with active disease that does not respond to conventional therapies. Anti-TNF therapy is very effective in AS, and eventually can be more effective than in rheumatoid arthritis. In 2003 Assessments in Ankylosing Spondylitis Group (ASAS) published international recommendations about the use of these agents in AS, which can be used as guidance in taking decisions and elaborating guidelines. To define their utilization it is necessary more studies about efficacy, toxicity and about ways of use.

Osteopoikilosis is a rare, benign and autosomal dominant bone disease. It is usually asymptomatic and diagnosed as a radiological finding. Plain X- Ray films show multiple sclerotic lesions on periarticular areas, epiphyses and metaphyses of long tubular bones. The authors describe two cases of osteopoikilosis in subjects belonging to the same family (brothers).

Juvenile idiopathic osteoporosis (JIO) is a rare condition of unknown aetiology, with pre-pubertal onset and frequently spontaneous remission after puberty. We report a case of a 14 years old boy, which two years before began dorso-lumbar pain with dorsal kyphosis. At the age of 12, he was on percentil 25 for height and had no other symptoms or alterations on physical exam. He had multiple vertebral fractures, a low serum vitamin D, and a Z-score in lumbar spine of -5,3. Diagnosis of JIO was made after excluding other causes of juvenile osteoporosis. He was submitted to pamidronate therapy and after six months showed clinical and bone mineral density improvement. At the age of 14 he is asymptomatic. The authors present this clinical case because of is rarity and to point out that although many cases have spontaneous remission, without any therapy, some may persist and become more serious, with pain and multiple fractures, justifying therapeutic intervention.
