Clinically inactive disease in a cohort of children with new-onset polyarticular juvenile idiopathic arthritis treated with early aggressive therapy: time to achievement, total duration, and predictors.

Objective: To determine the elapsed time while receiving aggressive therapy to the first observation of clinically inactive disease (CID), total duration of CID and potential predictors of this response in a cohort of children with recent onset of polyarticular juvenile idiopathic arthritis (poly-JIA).

Methods: Eighty-five children were randomized blindly to methotrexate (MTX), etanercept, and rapidly tapered prednisolone (MEP) or MTX monotherapy and assessed for CID over 1 year of treatment. Patients who failed to achieve intermediary endpoints were switched to open-label MEP treatment.

Trial of early aggressive therapy in polyarticular juvenile idiopathic arthritis.

Objective: To determine whether aggressive treatment initiated early in the course of rheumatoid factor (RF)-positive or RF-negative polyarticular juvenile idiopathic arthritis (JIA) can induce clinical inactive disease within 6 months.

Methods: Between May 2007 and October 2010, a multicenter, prospective, randomized, double-blind, placebo-controlled trial of 2 aggressive treatments was conducted in 85 children ages 2-16 years with polyarticular JIA of <12 months' duration. Patients received either methotrexate (MTX) 0.

A prospective study comparing celecoxib with naproxen in children with juvenile rheumatoid arthritis.

Objective: To compare the efficacy and safety of celecoxib and naproxen in children with juvenile rheumatoid arthritis (JRA).

Methods: In this multicenter, randomized, double-blind, noninferiority study, subjects with JRA were randomized to receive a target dose of celecoxib 3 mg/kg bid or 6 mg/kg bid, or a target dose of naproxen 7.5 mg/kg bid for 12 weeks (maximum allowed dose=600 mg total daily dose).

The PedsQL as a patient-reported outcome in children and adolescents with fibromyalgia: an analysis of OMERACT domains.

Background: Fibromyalgia is a chronic health condition characterized by widespread musculoskeletal pain, multiple tender points on physical examination, generalized muscular aching, stiffness, fatigue, nonrestorative sleep pattern, cognitive dysfunction, and mood disturbance. Recently, the Outcome Measures in Rheumatoid Arthritis Clinical Trials (OMERACT) Fibromyalgia Syndrome Workshop ranked and prioritized the domains that should be consistently measured in fibromyalgia clinical trials, specifically, pain, generic health-related quality of life, fatigue, sleep quality, and physical function. The focus of these deliberations was exclusively on adult patients, and to our knowledge, these domains have not been previously tested within a multidimensional framework in children and adolescents with fibromyalgia.

Efficacy of custom foot orthotics in improving pain and functional status in children with juvenile idiopathic arthritis: a randomized trial.

Objective: . To compare the clinical efficacy of custom foot orthotics, prefabricated "off-the-shelf" shoe inserts, and supportive athletic shoes worn alone, on reducing pain and improving function for children with juvenile idiopathic arthritis (JIA).

Methods: Children with JIA and foot pain (n = 40) were randomized to one of 3 groups receiving: (1) custom-made semirigid foot orthotics with shock absorbing posts (n = 15), (2) off-the-shelf flat neoprene shoe inserts (n = 12), or (3) supportive athletic shoes with a medial longitudinal arch support and shock absorbing soles worn alone (n = 13).

Leflunomide or methotrexate for juvenile rheumatoid arthritis.

Background: We compared the safety and efficacy of leflunomide with that of methotrexate in the treatment of polyarticular juvenile rheumatoid arthritis in a multinational, randomized, controlled trial.

Methods: Patients 3 to 17 years of age received leflunomide or methotrexate for 16 weeks in a double-dummy, blinded fashion, followed by a 32-week blinded extension. The rates of American College of Rheumatology Pediatric 30 percent responses (ACR Pedi 30) and the Percent Improvement Index were assessed at baseline and every 4 weeks for 16 weeks and every 8 weeks during the 32-week extension study.

The PedsQL Multidimensional Fatigue Scale in pediatric rheumatology: reliability and validity.

Objective: . The PedsQL (Pediatric Quality of Life Inventory) is a modular instrument designed to measure health related quality of life (HRQOL) in children and adolescents ages 2-18 years. The recently developed 18-item PedsQL Multidimensional Fatigue Scale was designed to measure fatigue in pediatric patients and comprises the General Fatigue Scale (6 items), Sleep/Rest Fatigue Scale (6 items), and Cognitive Fatigue Scale (6 items).

Childhood primary angiitis of the central nervous system: two biopsy-proven cases.

Primary angiitis of the central nervous system is a rare idiopathic vasculitis predominantly affecting the central nervous system. The literature includes 10 histologically confirmed cases in childhood. We identify two additional cases, one presenting with both uveitis and cerebrospinal fluid neutrophilic pleocytosis, which has not been reported previously, and demonstrate the importance of biopsy in suspected cases.

The PedsQL 4.0 Generic Core Scales: sensitivity, responsiveness, and impact on clinical decision-making.

The PedsQL 4.0 (Pediatric Quality of Life Inventory) Generic Core Scales are child self-report and parent proxy-report scales developed to measure health-related quality of life (HRQOL) in children and adolescents ages 2-18. The PedsQL 4.

The PedsQL in pediatric rheumatology: reliability, validity, and responsiveness of the Pediatric Quality of Life Inventory Generic Core Scales and Rheumatology Module.

Objective: The Pediatric Quality of Life Inventory (PedsQL) is a modular instrument designed to measure health-related quality of life (HRQOL) in children and adolescents ages 2-18 years. The 23-item PedsQL 4.0 Generic Core Scales are multidimensional child self-report and parent proxy-report scales developed as the generic core measure to be integrated with the PedsQL disease-specific modules.
