Uveitis treatment in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry: response to tumour necrosis factor inhibitors.

Objectives: Treatment with tumour necrosis factor inhibitors (TNFi) has significantly improved outcomes in uveitis associated with juvenile idiopathic arthritis (JIA-U). This study examines a CARRA Registry cohort of JIA-U patients on TNFi to analyse utilisation patterns and identify factors associated with response.

Methods: This retrospective cohort study used CARRA Registry data for subjects aged 0-25 with JIA-U who had uveitis onset before the age of 19, and ever used TNFi.

Key data elements for a successful pediatric rheumatology virtual visit: a survey within the PR-COIN network.

Introduction: Juvenile idiopathic arthritis (JIA) is the most common childhood rheumatic disease which is commonly monitored by a combination of history, physical examination, bloodwork, and imaging. The COVID-19 pandemic prompted a rapid shift to telemedicine to ensure that patients continued to receive healthcare. The shift to telemedicine changed the methodology and ability of healthcare providers to monitor their patients' progress, as they were unable to perform direct hands-on assessments.

Improving lupus care index documentation in patients with childhood-onset systemic lupus erythematosus.

Introduction: Childhood-onset systemic lupus erythematosus (c-SLE) presents unique challenges due to increased risk for severe morbidity and mortality compared to adult-onset SLE. Effective disease management relies on accurate disease assessment and documentation. Our project aimed to improve the documentation of the Lupus Care Index (LCI), a disease assessment bundle, by implementing a quality improvement (QI) initiative.

Preventing Teen Pregnancies on Teratogenic Drugs by Quality Improvement and Behavioral Economics.

Background: Adolescents with chronic disease engage in sexual activity similar to their healthy peers, with generally low utilization of contraception. Adolescents with rheumatic diseases prescribed teratogenic medications may be at risk for unplanned pregnancy.

Methods: Using structured quality improvement (QI) methods with behavior economic (BE) principles, a multidisciplinary team aimed to implement pregnancy prevention processes for females on high-risk medications.

Improving Vitamin D Screening in a Pediatric Rheumatology Clinic Using Structured Quality Improvement Process.

Introduction: Monitoring levels of 25-hydroxyvitamin D (25-OHD) is an integral part of bone health assessment in the general pediatric population, especially in at-risk populations such as children with juvenile idiopathic arthritis (JIA), childhood-onset systemic lupus erythematosus (c-SLE), and juvenile dermatomyositis (JDM). However, only 38% of the patients with JIA, c-SLE, and JDM receiving care at Nationwide Children's Hospital Rheumatology clinic in 2016 had a 25-OHD level ordered in the preceding year. The objective of this project was to increase the percentage of 25-OHD levels ordered in patients with JIA, c-SLE, and JDM from 38% to 80% in 11 months and sustain it for 6 months.

2021 American College of Rheumatology Guideline for the Treatment of Juvenile Idiopathic Arthritis: Therapeutic Approaches for Oligoarthritis, Temporomandibular Joint Arthritis, and Systemic Juvenile Idiopathic Arthritis.

Objective: To provide updated guidelines for pharmacologic management of juvenile idiopathic arthritis (JIA), focusing on treatment of oligoarthritis, temporomandibular joint (TMJ) arthritis, and systemic JIA with and without macrophage activation syndrome. Recommendations regarding tapering and discontinuing treatment in inactive systemic JIA are also provided.

Methods: We developed clinically relevant Patient/Population, Intervention, Comparison, and Outcomes questions.

2021 American College of Rheumatology Guideline for the Treatment of Juvenile Idiopathic Arthritis: Recommendations for Nonpharmacologic Therapies, Medication Monitoring, Immunizations, and Imaging.

Objective: To provide recommendations for the management of juvenile idiopathic arthritis (JIA) with a focus on nonpharmacologic therapies, medication monitoring, immunizations, and imaging, irrespective of JIA phenotype.

Methods: We developed clinically relevant Patient/Population, Intervention, Comparison, and Outcomes questions. After conducting a systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation approach was used to rate the quality of evidence (high, moderate, low, or very low).

Objective: To provide updated guidelines for pharmacologic management of juvenile idiopathic arthritis (JIA), focusing on treatment of oligoarthritis, temporomandibular joint (TMJ) arthritis, and systemic JIA with and without macrophage activation syndrome. Recommendations regarding tapering and discontinuing treatment in inactive systemic JIA are also provided.

Methods: We developed clinically relevant Patient/Population, Intervention, Comparison, and Outcomes questions.

Human Complement C4B Allotypes and Deficiencies in Selected Cases With Autoimmune Diseases.

Human complement C4 is one of the most diverse but heritable effectors for humoral immunity. To help understand the roles of C4 in the defense and pathogenesis of autoimmune and inflammatory diseases, we determined the bases of polymorphisms including the frequent genetic deficiency of C4A and/or C4B isotypes. We demonstrated the diversities of C4A and C4B proteins and their gene copy number variations (CNVs) in healthy subjects and patients with autoimmune disease, such as type 1 diabetes, systemic lupus erythematosus (SLE) and encephalitis.

Reintroduction of immunosuppressive medications in pediatric rheumatology patients with histoplasmosis: a case series.

Background: Children with rheumatic diseases (cRD) receiving immunosuppressive medications (IM) are at a higher risk for acquiring potentially lethal pathogens, including Histoplasma capsulatum (histoplasmosis), a fungal infection that can lead to prolonged hospitalization, organ damage, and death. Withholding IM during serious infections is recommended yet poses risk of rheumatic disease flares. Conversely, reinitiating IM increases risk for infection recurrence.

Exploring Pediatric Tele-Rheumatology Practices During COVID-19: A Survey of the PRCOIN Network.

Healthcare providers were rapidly forced to modify the way they practiced medicine during the coronavirus disease 2019 (COVID-19) pandemic. Many providers transitioned from seeing their patients in person to virtually using telemedicine platforms with limited training and experience using this medium. In pediatric rheumatology, this was further complicated as musculoskeletal exams typically require hands-on assessment of patients.

Improving eye screening practice among pediatric rheumatology patients receiving hydroxychloroquine.

Objective: Hydroxychloroquine (HCQ) is commonly used in the treatment of various autoimmune diseases related to its many benefits and favorable safety profile. Although HCQ retinopathy was considered to be uncommon, a prevalence of 7.5% was described in a recent study making early detection critical.

Previsit Planning Improves Pneumococcal Vaccination Rates in Childhood-Onset SLE.

Background: Childhood-onset systemic lupus erythematosus (c-SLE) is a complex autoimmune disease that requires systemic immunosuppressive therapy. Infections are the second leading cause of death in these patients, with invasive pneumococcal infections being a major preventable cause of morbidity and mortality. Pneumococcal vaccination is recommended in this population; however, vaccination rates remain low.

Opposite Profiles of Complement in Antiphospholipid Syndrome (APS) and Systemic Lupus Erythematosus (SLE) Among Patients With Antiphospholipid Antibodies (aPL).

APS is the association of antiphospholipid antibodies (aPL) with thromboses and/or recurrent pregnancy loss (RPL). Among patients with SLE, one-third have aPL and 10-15% have a manifestation of secondary APS. Animal studies suggested that complement activation plays an important role in the pathogenesis of thrombosis and pregnancy loss in APS.

Utility of Neurodiagnostic Studies in the Diagnosis of Autoimmune Encephalitis in Children.

Background: Autoimmune encephalitis is currently a clinical diagnosis without widely accepted diagnostic criteria, often leading to a delay in diagnosis. The utility of magnetic resonance imaging (MRI) and electroencephalography (EEG) in this disease is unknown. The objective of this study was to identify disease-specific patterns of neurodiagnostic studies (MRI and EEG) for autoimmune encephalitis in children.

Two cases of thrombosis in patients with antiphospholipid antibodies during treatment of immune thrombocytopenia with romiplostim, a thrombopoietin receptor agonist.

Introduction: Romiplostim is a thrombopeitin-receptor agonist approved for raising platelet counts in patients with immune thrombocytopenia (ITP). Several hematologic adverse effects have been reported including acute myeloid leukemia, myelofibrosis, and thrombosis.

Methods: We report two cases, one pediatric and one adult patient, who had antiphospholipid antibodies and received romiplostim for ITP.
