Clinical features and long-term outcomes of systemic lupus erythematosus: comparative data of childhood, adult and late-onset disease in a national register.

Systemic lupus erythematosus (SLE) affects predominantly women at reproductive age but may present at any age. Age at disease onset has a modulating effect on presentation and course of disease, but controversies persist regarding its impact on long-term outcome. Our aims were to characterize clinical features, co-morbidities and cumulative damage in childhood-onset, adult-onset and late-onset SLE. Patients with childhood-onset SLE fulfilling ACR 1997 criteria were identified in a nationwide register-Reuma.pt/SLE (N = 89) and compared with adult-onset and late-onset counterparts matched 1:1:1 for disease duration. 267 SLE patients with mean disease duration of 11.9 ± 9.3 years were analyzed. Skin (62 %), kidney (58 %), neurological (11 %) and hematologic involvement (76 %) were significantly more common in childhood-onset SLE and disease activity was higher in this subset than in adult- and late-onset disease (SLEDAI-2K 3.4 ± 3.8 vs. 2.2 ± 2.7 vs. 1.6 ± 2.8, respectively; p = 0.004). Also, more childhood-onset patients received cyclophosphamide (10 %) and mycophenolate mofetil (34 %). A greater proportion of women (96 %), prevalence of arthritis (89 %) and anti-SSA antibodies (34 %) were noted in the adult-onset group. There was a significant delay in the diagnosis of SLE in older ages. Co-morbidities such as hypertension, diabetes and thyroid disease were significantly more frequent in late-onset SLE, as well as the presence of irreversible damage evaluated by the SLICC/ACR damage index (20 vs. 26 vs. 40 %; p < 0.001). Greater organ involvement as well as the frequent need for immunosuppressants supports the concept of childhood-onset being a more severe disease. In contrast, disease onset is more indolent but co-morbidity burden and irreversible damage are greater in late-onset SLE, which may have implications for patients' management.

[Protracted Febrile Myalgia Syndrome with Henoch-Schönlein Purpura: an atypical presentation of Familial Mediterranean Fever]. / Protracted Febrile Myalgia Syndrome com Púrpura de Henoch-Schönlein: forma atípica de apresentação de febre mediterrânica familiar.

Familial Mediterranean Fever (FMF) is an hereditary autosomal recessive disease characterized by recurrent attacks of fever, arthritis and serositis: peritonitis, pleurisy and/or pericarditis. Its main complication is systemic AA amyloidosis. The authors present a case of a 8-years-old female child with african ancestry, who was admitted three times since 5 years-old with abdominal pain, fever and high acute phase reactants. At the first admission appendectomy was made and at the third hospital admission the clinical picture was accompanied by myalgia, purpuric lesions and non nephrotic proteinuria. A renal biopsy was performed and was compatible with Henoch-Schönlein nephritis. Serum Amyloid A protein had high levels - 92 mg/L (> 6.8) and a diagnosis of Familial Mediterranean Fever was confirmed by genetic test (homozygote for M694V in MEFV gene). She started colchicine and is doing well, without any further complaints. FMF must be considered in the differential diagnosis of recurrent attacks of fever and abdominal pain in children, even with an atypical presentation (p.e. Protracted Febrile Myalgia Syndrome). Genetic study allows the confirmation of the diagnosis and has prognostic implications.

Inhibition of radiographic progression with combination etanercept and methotrexate in patients with moderately active rheumatoid arthritis previously treated with monotherapy.

OBJECTIVE: To determine the effect of changing from etanercept or methotrexate monotherapy to etanercept plus methotrexate combination therapy on radiographic progression in rheumatoid arthritis (RA) patients. METHODS: Patients enrolled in this 1-year open-label study previously completed a 3-year blinded study in which they received methotrexate or etanercept monotherapy or the combination of both. All patients received the combination of etanercept 25 mg subcutaneously twice weekly plus oral methotrexate up to 20 mg/week. The primary radiographic endpoint was a change in modified total Sharp score (TSS), as assessed by blinded readers. RESULTS: At baseline, patients previously receiving methotrexate monotherapy (etanercept-added, n = 52) or etanercept monotherapy (methotrexate-added, n = 68) had moderate disease activity levels (mean disease activity score (DAS) of 2.6 and 2.5, respectively), whereas patients previously receiving combination therapy (n = 90) had a low disease activity level (mean DAS of 2.0). The addition of etanercept to methotrexate monotherapy resulted in a significant reduction in radiographic progression (p<0.05). Mean TSS changes in the previous year versus the current year were +1.79 versus +0.25 for the etanercept-added group (p<0.05); +0.51 versus -0.18 for the methotrexate-added group (NS) and +0.42 versus +0.24 for the combination group (NS). CONCLUSION: In these RA patients with on average moderate disease activity despite previous methotrexate monotherapy, combination treatment with etanercept and methotrexate inhibited radiographic progression and improved radiographic outcomes. These data, in conjunction with the previously published clinical data, support the use of combination therapy in RA patients with moderate disease activity.

Fracture incidence and changes in quality of life in women with an inadequate clinical outcome from osteoporosis therapy: the Observational Study of Severe Osteoporosis (OSSO).

UNLABELLED: In this observational study of women with an inadequate clinical outcome to osteoporosis therapy, those with a fracture at baseline were more likely to sustain an incident fracture and have a worse health-related quality of life than those without prior fracture. INTRODUCTION: The Observational Study of Severe Osteoporosis (OSSO) was designed to assess the fracture incidence and health-related quality of life (HRQoL) in women with an inadequate clinical outcome to osteoporosis therapy. METHODS: Post-menopausal women (N=1,885) with established osteoporosis and an inadequate clinical response to osteoporosis drug therapy defined as: a) a fragility fracture despite therapy for one year (index fracture, N=988), or b) discontinued drug therapy due to adverse effects and/or non-compliance (N=897), were assessed during one year for HRQoL using the EQ-5D and the QUALEFFO questionnaires. RESULTS: One hundred and sixty-six (8.8%) women had a total of 209 incident fractures (1,139 fractures/10,000 women-years). Women with an index fracture were more likely to sustain an incident fracture than those without prior fractures (hazard ratio 1.91; 95% CI: 1.37-2.66; p<0.001). Co-morbidities or antidepressant use at baseline also increased the risk of incident fracture. Median total EQ-5D Health State Values and QUALEFFO scores were worse in women with an incident fracture regardless of index fracture status. The worst scores were reported in the EQ-5D sub-domains of self-care, usual activities and pain/discomfort. CONCLUSIONS: Women with an inadequate response to osteoporosis therapy had a high rate of incident fracture which had an adverse impact on HRQoL.

The safety and efficacy of adding etanercept to methotrexate or methotrexate to etanercept in moderately active rheumatoid arthritis patients previously treated with monotherapy.

OBJECTIVE: To determine if adding etanercept (ETN) to methotrexate (MTX) or MTX to ETN for 52 weeks in rheumatoid arthritis (RA) patients with moderate disease activity provides higher efficacy. METHODS: All patients (n = 227) received open-label ETN 25 mg subcutaneously twice-weekly and MTX orally up to 20 mg weekly for 52 weeks and had completed a 3-year study in which patients received MTX, ETN or combination therapy. Endpoints were based on Disease Activity Score (DAS) and European League Against Rheumatism (EULAR) responses. RESULTS: Patients previously receiving combination therapy (Combination group; n = 96) had a lower disease activity at baseline. The mean DAS for those previously receiving MTX (ETN-added group; n = 55) and previously receiving ETN (MTX-added group; n = 76) were in the moderate disease activity range at baseline; Combination patients had a low disease activity. The greatest increase in DAS remission rates from baseline to week 52 was in the ETN-added group (23.6% to 41.8%, p<0.01), although Combination (37.6% to 50.0%, p<0.01) and MTX-added (26.7% to 36.8%, p = NS) also demonstrated improvements. DAS low disease activity and EULAR responses showed similar results. No new safety issues were identified. CONCLUSION: RA patients who were partial responders to long-term MTX or etanercept monotherapy obtained a higher efficacy with combination therapy. Responses achieved by patients with combination therapy after 3 years in the previous study were sustained or improved during the fourth year of treatment. This trial supports the higher therapeutic effect of combination treatment with etanercept and MTX in RA patients with moderate disease activity despite monotherapy with one of the two agents.

[Guidelines for prescribing and monitoring biologic therapies in juvenile idiopathic arthritis]. / Consensos para início e manutenção de teraprêutica biológica na artrite idiopática juvenil.

The Pediatric RheumatologyWorking Group of the Portuguese Society of Rheumatology recommends the use of biological treatments in children with polyarticular course Juvenile Idiopathic Arthritis (JIA) with active disease (5 or more active joints) refractory to subcutaneous or intramuscular methotrexate (MTX) 15 mg/m(2)/week during 3 to 6 months. If toxicity occurs, or if there is contraindication for the use of MTX in this optimum dose, biological treatment can be started, as a first option, or the use of other conventional Disease ModifyingAnti Rheumatic Drug (DMARD) either alone or in combination with MTX might be considered. Prior to starting treatment, children should be screened for latent tuberculosis through clinical evaluation, chest X ray and PPD skin test. The suspension of the biological treatment should be considered if the American College of Rheumatology (ACR) definition of improvement in JIA is not fulfilled in two consecutive visits 3 months apart. Etanercept is the only biological agent currently approved for JIA in Portugal. In refractory cases the use of infliximab is accepted, in accordance with preliminary published evidence. In case of systemic manifestations of JIA refractory to conventional treatment, anakinra can be considered.

Health-related quality of life of patients with juvenile idiopathic arthritis coming from 3 different geographic areas. The PRINTO multinational quality of life cohort study.

OBJECTIVES: To compare health-related quality of life (HRQL) and to identify clinical determinants for poor HRQL of patients with juvenile idiopathic arthritis (JIA) coming from three geographic areas. METHODS: The HRQL was assessed through the Child Health Questionnaire (CHQ). A total of 30 countries were included grouped in three geographic areas: 16 countries in Western Europe; 10 in Eastern Europe; and four in Latin America. Potential determinants of poor HRQL included demographic data, physician's and parent's global assessments, measures of joint inflammation, disability as measured by Childhood Health Assessment Questionnaire (CHAQ) and erythrocyte sedimentation rate. Poor HRQL was defined as a CHQ physical summary score (PhS) or psychosocial summary score (PsS) <2 S.D. from that of healthy children. RESULTS: A total of 3167 patients with JIA, younger than 18 yrs, were included in this study. The most affected health concepts (<2 S.D. from healthy children) that differentiate the three geographic areas include physical functioning, bodily pain/discomfort, global health, general health perception, change in health with respect to the previous year, self-esteem and family cohesion. Determinants for poor HRQL were similar across geographic areas with physical well-being mostly affected by the level of disability while the psychosocial well-being by the intensity of pain. CONCLUSION: We found that patients with JIA have a significant impairment of their HRQL compared with healthy peers, particularly in the physical domain. Disability and pain are the most important determinants of physical and psychosocial well-being irrespective of the geographic area of origin.

Characterization of patients with an inadequate clinical outcome from osteoporosis therapy: the Observational Study of Severe Osteoporosis (OSSO).

BACKGROUND: Osteoporotic fractures remain a major public health problem. Currently available osteoporosis therapies significantly reduce the risk of fractures, but up to 50% of patients have an inadequate clinical outcome to therapy. AIM: To describe the clinical and quality of life (QOL) of a study population meeting a proposed definition of inadequate clinical outcome to osteoporosis therapy, recruited for the Observational Study of Severe Osteoporosis (OSSO). DESIGN: Cross-sectional, observational study. METHODS: Post-menopausal women with osteoporosis (n = 2314) were divided into Group 1 (those who had previously experienced a fragility fracture despite osteoporosis drug therapy for at least 12 months) (n = 1309, 57%), or Group 2 (those who had previously discontinued osteoporosis drug therapy due to non-compliance or side-effects) (n = 1005; 43%). Baseline clinical characteristics, quality of life (QOL) and osteoporosis/falls risk factors were analysed. RESULTS: The overall population had low BMD (mean +/- SD T-score at lumbar spine -3.1 +/- 1.1), and risk factors for fracture such as previous fractures (67.8%), family history (15.1%), and prolonged glucocorticoid use (17.5%). QOL was poor: total QUALEFFO and EQ-5D scores were 46.8 +/- 18.7, and 0.50 +/- 0.33, respectively. Patients in Group 1 had higher age and body mass index, fewer hours of exercise, more previous fragility fractures and falls, and poorer QOL scores. DISCUSSION: Our definition of inadequate clinical outcome from osteoporosis drug therapy identifies a severe osteoporosis cohort with poor QOL and increased fracture risk. Using such a definition may lead to earlier recognition of inadequate clinical outcome to osteoporosis therapy, and improved interventions and results.

Patient reported outcomes in a trial of combination therapy with etanercept and methotrexate for rheumatoid arthritis: the TEMPO trial.

OBJECTIVE: To compare patient reported measures of function, health related quality of life (QoL), and satisfaction with medication among patients with rheumatoid arthritis (RA) treated with methotrexate (MTX), etanercept, or both for up to 1 year. METHODS: In a 52 week, double blind, clinical trial, patients with active RA were randomised to receive etanercept 25 mg twice weekly, methotrexate up to 20 mg weekly, or combination therapy. The Health Assessment Questionnaire (HAQ) disability index, EuroQoL health status visual analogue scale (EQ-5D VAS), patient global assessment, and patient general health VAS were administered at baseline and weeks 2, 4, 8, 12, 16, 20, 24, 32, 40, 48, and 52. Satisfaction with the medication was compared at 52 weeks. RESULTS: Of 682 enrolled patients, 522 completed 52 weeks of treatment. Mean improvement from baseline in HAQ score was 0.65, 0.70, and 1.0 for MTX, etanercept, and the combination, respectively. The mean percentage and absolute improvement in the HAQ was significantly higher (p<0.01) for combination therapy than for either of the monotherapies. Combination therapy produced significantly more rapid achievement of HAQ < or =0.5 sustained for 6 months than either of the monotherapies (p<0.01). Compared with patients receiving monotherapy, those receiving combination therapy achieved a significantly better (p<0.05) health state as measured by the EQ-5D VAS (mean (SD) 63.7 (3.2), 66.8 (3.2), 72.7 (3.1) for MTX, etanercept, and the combination, respectively). Results were similar for other assessments (p<0.01). Patients in combination and etanercept groups were significantly more likely (p<0.0001, p = 0.0009, respectively) to report satisfaction with the medication. CONCLUSIONS: Combination therapy with etanercept and methotrexate improved function, QoL, and satisfaction with the medication significantly more than monotherapy.

PRINTO/PRES international website for families of children with rheumatic diseases: www.pediatric-rheumatology.printo.it.

OBJECTIVE: To prepare a website for families and health professionals containing up to date information about paediatric rheumatic diseases (PRD). METHODS: Firstly, paediatric rheumatology centres and family self help associations were surveyed to characterise current clinical practice of physicians providing care for children with PRD, research activities, and training facilities of each centre. Secondly, international consensus was reached on the content of the website. Finally, the website was developed and the texts translated. RESULTS: The web page contains three main sections: (a) description for families of the characteristics of 15 PRD; (b) list of paediatric rheumatology centres; (c) contact information for family self help associations. A version for 45 countries in 52 languages (with another three in progress) is now available on the web. 291 surveys from 171 centres and 102 family associations were received from 42 countries. The median proportion of time spent in paediatric practice in the centres examined was 100%, with 70% of this time dedicated to paediatric rheumatology. 90% of the centres were willing to perform clinical trials in the future. CONCLUSIONS: The PRINTO/PRES website provides a well defined and competent set of information about PRD, with appropriate multiple translated versions and easy web navigational direction.

The Portuguese version of the Childhood Health Assessment Questionnaire (CHAQ) and the Child Health Questionnaire (CHQ).

We report herein the results of the cross-cultural adaptation and validation into the Portuguese language of the parent's version of two health related quality of life instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific health instrument that measures functional ability in daily living activities in children with juvenile idiopathic arthritis (JIA). The Child Health Questionnaire (CHQ) is a generic health instrument designed to capture the physical and psychosocial well being of children independently from the underlying disease. The Portuguese CHAQ CHQ were fully validated with 3 forward and 3 backward translations. A total of 130 subjects were enrolled: 69 patients with JIA (32% systemic onset, 19% polyarticular onset, 26% extended oligoarticular subtype, and 23% persistent oligoarticular subtype) and 61 healthy children. The CHAQ clinically discriminated between healthy subjects and JIA patients, with the systemic, polyarticular and extended oligoarticular subtypes having a higher degree of disability, pain, and a lower overall well being when compared to their healthy peers. Also the CHQ clinically discriminated between healthy subjects and JIA patients, with the systemic onset, polyarticular onset and extended oligoarticular subtypes having a lower physical and psychosocial well being when compared to their healthy peers. In conclusion the Portuguese version of the CHAQ-CHQ is a reliable, and valid tool for the functional, physical and psychosocial assessment of children with JIA.

The Brazilian version of the Childhood Health Assessment Questionnaire (CHAQ) and the Child Health Questionnaire (CHQ).

We report the cross-cultural adaptation and validation into Brazilian-Portuguese of the parent's version of two health related quality of life instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific health instrument that measures functional ability in daily living activities in children with juvenile idiopathic arthritis (JIA). The Child Health Questionnaire (CHQ) is a generic health instrument designed to capture the physical and psychosocial well-being of children regardless the underlying disease. The Brazilian CHAQ was revalidated, while the CHQ has been derived from the Portuguese version. A total of 471 subjects were enrolled: 157 patients with JIA (27% systemic onset, 38% polyarticular onset, 9% extended oligoarticular subtype, and 26% persistent oligoarticular subtype) and 314 healthy children. The CHAQ discriminated clinically healthy subjects from JIA patients, with the systemic, polyarticular and extended oligoarticular subtypes having a higher degree of disability, pain, and lower overall well-being scores when compared to their healthy peers. Also the CHQ discriminated clinically healthy subjects from JIA patients, with the systemic onset, polyarticular onset and extended oligoarticular subtypes having a lower physical and psychosocial well-being score when compared to their healthy peers. In conclusion the Brazilian versions of the CHAQ-CHQ are reliable and valid tools for the combined physical and psychosocial assessment of children with JIA.

Two-year effects of alendronate on bone mineral density and vertebral fracture in patients receiving glucocorticoids: a randomized, double-blind, placebo-controlled extension trial.

OBJECTIVE: To evaluate the continued efficacy and safety of alendronate (ALN) for up to 2 years in patients receiving glucocorticoids. METHODS: This is a 12-month extension of a previously completed 1-year trial of daily ALN, performed to evaluate the effects of ALN over a total of 2 years in 66 men and 142 women continuing to receive at least 7.5 mg of prednisone or equivalent daily. All patients received supplemental calcium and vitamin D. The primary end point was the mean percentage change in lumbar spine bone mineral density (BMD) from baseline to 24 months. Other outcomes included changes in hip and total body BMD, biochemical markers of bone turnover, radiographic joint damage of the hands, and vertebral fracture incidence. RESULTS: The mean (+/-SEM) lumbar spine BMD increased by 2.8 +/- 0.6%, 3.9 +/- 0.7%, and 3.7 +/- 0.6%, respectively, in the groups that received 5 mg, 10 mg, and 2.5/10 mg of ALN daily (P < or = 0.001) and decreased by -0.8 +/- 0.6% in the placebo group (P not significant) over 24 months. In patients receiving any dose of ALN, BMD was increased at the trochanter (P < or = 0.05) and maintained at the femoral neck. Total body BMD was increased in patients receiving 5 or 10 mg ALN (P < or = 0.01). These 2 dose levels of ALN were more effective than placebo at all sites (P < or = 0.05). Bone turnover markers (N-telopeptides of type I collagen and bone-specific alkaline phosphatase) decreased 60% and 25%, respectively, during treatment with ALN (P < or = 0.05). There were fewer patients with new vertebral fractures in the ALN group versus the placebo group (0.7% versus 6.8%; P = 0.026). The safety profile was similar between treatment groups. CONCLUSION: Alendronate is an effective, well-tolerated therapy for the prevention and treatment of glucocorticoid-induced osteoporosis, with sustained treatment advantages for up to 2 years.

Bone mineral density and androgen levels in elderly males.

To clarify the relationship of sex male hormones and bone in men, we studied in 140 healthy elderly men (aged 55-90 years) the relation between serum levels of androgens and related sex hormones, bone mineral density (BMD) at different sites, and other parameters related to bone metabolism. Our results show a slight decrease of serum-free testosterone with age, with an increase of follicle stimulating hormone (FSH) and luteinizing hormone (LH) in a third of the elderly subjects studied. BMD decreased significantly with age in all regions studied, except in the lumbar spine. We found a positive correlation between body mass index (BMI) and BMD at the lumbar spine and femoral neck (P < 0.001). No relationship was found (uni- and multivariate regression analysis) between serum androgens or sex hormone-binding globulin (SHBG) and BMD. We found a positive correlation of vitamin D binding protein (DBP) and osteocalcin with lumbar spine BMD and with BMI, DBP, IGF-1, and PTH with femoral neck BMD. In conclusion, there is a slight decline in free testosterone and BMD in the healthy elderly males. However, sex male hormones are not correlated to the decrease in hip BMD. Other age-related factors must be associated with bone loss in elderly males.

Double-blind comparison of efficacy and gastroduodenal safety of diclofenac/misoprostol, piroxicam, and naproxen in the treatment of osteoarthritis.

OBJECTIVES: To compare the efficacy and gastroduodenal safety of a fixed-dose combination of diclofenac sodium 50 mg and misoprostol 200 micrograms twice daily with those of piroxicam 10 mg twice daily and naproxen 375 mg twice daily in patients with osteoarthritis. METHODS: A 4 week, randomised, double-blind, parallel-group, multicentre study was conducted in 643 patients with symptomatic osteoarthritis of the hip and/or knee, who required continuous non-steroidal anti-inflammatory drug therapy for 4 weeks and who were without significant upper gastrointestinal damage as confirmed by endoscopy. RESULTS: For patients who had pre- and post-treatment endoscopic examinations, gastroduodenal ulcers developed in 3 (1.5%) of 200 patients treated with diclofenac/misoprostol, 21 (10.3%) of 204 piroxicam-treated patients, and 17 (8.6%) of 198 patients receiving naproxen (Chi square = 13.771, p = 0.001). The improvement in the osteoarthritis severity index was greater in the diclofenac/misoprostol group than in the piroxicam group (p = 0.004). Changes in physician and patient global assessments showed no significant differences between treatment groups. The incidences of diarrhoea and abdominal pain were higher in the diclofenac/misoprostol group than in the piroxicam and naproxen groups. CONCLUSIONS: Diclofenac/misoprostol at twice daily dosing is associated with significantly fewer gastroduodenal ulcers than either piroxicam or naproxen. The efficacy of diclofenac/misoprostol in treating the signs and symptoms of osteoarthritis is at least comparable to that of piroxicam and naproxen.

Problems related to systemic glucocorticoid therapy in children.

Glucocorticoids (GC) are among the most potent antiinflammatory agents that can be used in the treatment of rheumatic diseases. Their mechanisms of action are multiple and complex. As would be expected of any drug with a wide range of actions, systemic GC have many side effects, some severe and some of which like growth suppression, are specific to childhood. To prescribe GC with an acceptable incidence of side effects, the following recommendations should be heeded: use only in well established indications, use at the lowest possible dose, as a single, daily administration, or as an alternate day regimen whenever possible, use concomitantly with steroid sparing agents (e.g., NSAID, disease modifying agents in rheumatic diseases (DMARD), antiepileptics) and choose the GC with the fewest side effects.

The safety of Arthrotec in patients with rheumatoid arthritis or osteoarthritis: an assessment of the upper gastrointestinal tract by endoscopy.

Two double-blind comparative studies were conducted to determine the upper gastrointestinal safety of Arthrotec, a combination of 50 mg of diclofenac and 200 micrograms of misoprostol versus 50 mg of diclofenac. In one study, rheumatoid arthritis patients were randomly given Arthrotec or diclofenac 2 or 3 times daily for 12 weeks. Endoscopy was performed before and after treatment. At the termination of treatment, among the 290 patients with rheumatoid arthritis, gastroduodenal ulcers were found in 4% of the Arthrotec-treated patients and in 11% of the diclofenac-treated patients (P = 0.034). In the second study, osteoarthritis patients were randomly given Arthrotec or diclofenac 2 or 3 times daily for 4 weeks. Endoscopy was performed before and after treatment. Among the 329 patients with osteoarthritis, gastroduodenal ulcers were found in none of the Arthrotec patients and in 4% of the diclofenac patients (P = 0.015).
