A pilot trial of integrating the Patient-Reported Outcome Measurement Information System (PROMIS®) into rheumatology care.

Objectives: Utilising Patient-Reported Outcomes Measurement Information System (PROMIS®) questionnaires can enhance clinical care by measuring longitudinal changes in symptom severity as reported by the patient. The aim of this pilot study was to assess the feasibility and impact of incorporating PROMIS® questionnaires at the point-of-care in rheumatology practice.

Methods: Patients with rheumatic diseases and decrements in ≥1 PROMIS® domain (pain intensity, physical function, or sleep disturbance) were stratified by their concerning domain, then randomised to either receive an interpretation of their PROMIS® scores prior to their rheumatology appointment (Arm 1) or to usual care (Arm 2) (ClinicalTrials.

Viral escape mutations do not account for non-protection from SIVmac239 challenge in RhCMV/SIV vaccinated rhesus macaques.

Simian immunodeficiency virus (SIV) vaccines based upon 68-1 Rhesus Cytomegalovirus (RhCMV) vectors show remarkable protection against pathogenic SIVmac239 challenge. Across multiple independent rhesus macaque (RM) challenge studies, nearly 60% of vaccinated RM show early, complete arrest of SIVmac239 replication after effective challenge, whereas the remainder show progressive infection similar to controls. Here, we performed viral sequencing to determine whether the failure to control viral replication in non-protected RMs is associated with the acquisition of viral escape mutations.

Real-World Experience With Avacopan in Antineutrophil Cytoplasmic Autoantibody-Associated Vasculitis.

Introduction: Postmarketing data on outcomes of avacopan use in antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV) are lacking.

Methods: We performed a multicenter retrospective analysis of 92 patients with newly diagnosed or relapsing AAV who received therapy with avacopan. The coprimary outcome measures were clinical remission at 26 and 52 weeks.

Tocilizumab in giant cell arteritis: an update for the clinician.

Purpose Of Review: The recent approval of tocilizumab (TCZ) for the treatment of giant cell arteritis (GCA) has changed the landscape for management of this disease. Herein, we review recent literature addressing practical questions for the clinician regarding the use of TCZ in GCA. We evaluate efficacy of TCZ across different disease phenotypes, optimal dosing and formulation, treatment-related toxicity, recommendations for monitoring disease, and duration of therapy.

Late gene expression-deficient cytomegalovirus vectors elicit conventional T cells that do not protect against SIV.

Rhesus cytomegalovirus-based (RhCMV-based) vaccine vectors induce immune responses that protect ~60% of rhesus macaques (RMs) from SIVmac239 challenge. This efficacy depends on induction of effector memory-based (EM-biased) CD8+ T cells recognizing SIV peptides presented by major histocompatibility complex-E (MHC-E) instead of MHC-Ia. The phenotype, durability, and efficacy of RhCMV/SIV-elicited cellular immune responses were maintained when vector spread was severely reduced by deleting the antihost intrinsic immunity factor phosphoprotein 71 (pp71).

Myeloid cell tropism enables MHC-E-restricted CD8 T cell priming and vaccine efficacy by the RhCMV/SIV vaccine.

The strain 68-1 rhesus cytomegalovirus (RhCMV)-based vaccine for simian immunodeficiency virus (SIV) can stringently protect rhesus macaques (RMs) from SIV challenge by arresting viral replication early in primary infection. This vaccine elicits unconventional SIV-specific CD8 T cells that recognize epitopes presented by major histocompatibility complex (MHC)-II and MHC-E instead of MHC-Ia. Although RhCMV/SIV vaccines based on strains that only elicit MHC-II- and/or MHC-Ia-restricted CD8 T cells do not protect against SIV, it remains unclear whether MHC-E-restricted T cells are directly responsible for protection and whether these responses can be separated from the MHC-II-restricted component.

Therapeutic advances in eosinophilic granulomatosis with polyangiitis.

Purpose Of Review: In recent years, therapeutic advances in eosinophilic granulomatosis with polyangiitis (EGPA) have changed our treatment paradigm. This review will summarize and discuss updates in management of EGPA, with a particular focus on biologic therapies.

Recent Findings: The anti-interleukin (IL)-5 agent mepolizumab (the first FDA-approved drug specifically for EGPA) is effective in induction and maintenance of remission particularly in patients with predominantly asthma and allergic manifestations, though efficacy in ANCA-positive, vasculitic disease is unclear; additional anti-IL-5 agents are under study.

Randomised clinical trial: a phase 1b study of GB004, an oral HIF-1α stabiliser, for treatment of ulcerative colitis.

Background: Epithelial barrier dysfunction contributes to a dysregulated intestinal immune response in ulcerative colitis (UC). GB004 is an orally administered, small molecule, gut-targeted stabiliser of hypoxia-inducible factor-1α, a transcription factor with protective roles at the epithelial layer of the inflamed gut.

Aims: To evaluate safety, pharmacokinetics, pharmacodynamics and efficacy of GB004 in patients with active UC.

Passive Smoking Throughout the Life Course and the Risk of Incident Rheumatoid Arthritis in Adulthood Among Women.

Objective: To investigate passive smoking throughout the life course and the risk of rheumatoid arthritis (RA), while accounting for personal smoking.

Methods: We analyzed the Nurses' Health Study II prospective cohort, using information collected via biennial questionnaires. We assessed the influence of 1) maternal smoking during pregnancy (in utero exposure), 2) childhood parental smoking, and 3) years lived with smokers since age 18.

Modulation of MHC-E transport by viral decoy ligands is required for RhCMV/SIV vaccine efficacy.

Strain 68-1 rhesus cytomegalovirus (RhCMV) vectors expressing simian immunodeficiency virus (SIV) antigens elicit CD8 T cells recognizing epitopes presented by major histocompatibility complex II (MHC-II) and MHC-E but not MHC-Ia. These immune responses mediate replication arrest of SIV in 50 to 60% of monkeys. We show that the peptide VMAPRTLLL (VL9) embedded within the RhCMV protein Rh67 promotes intracellular MHC-E transport and recognition of RhCMV-infected fibroblasts by MHC-E-restricted CD8 T cells.

Cytomegaloviral determinants of CD8 T cell programming and RhCMV/SIV vaccine efficacy.

Simian immunodeficiency virus (SIV) insert-expressing, 68-1 rhesus cytomegalovirus (RhCMV/SIV) vectors elicit major histocompatibility complex E (MHC-E)- and MHC-II-restricted, SIV-specific CD8 T cell responses, but the basis of these unconventional responses and their contribution to demonstrated vaccine efficacy against SIV challenge in the rhesus monkeys (RMs) have not been characterized. We show that these unconventional responses resulted from a chance genetic rearrangement in 68-1 RhCMV that abrogated the function of eight distinct immunomodulatory gene products encoded in two RhCMV genomic regions ( and ), revealing three patterns of unconventional response inhibition. Differential repair of these genes with either RhCMV-derived or orthologous human CMV (HCMV)-derived sequences (; ) leads to either of two distinct CD8 T cell response types-MHC-Ia-restricted only or a mix of MHC-II- and MHC-Ia-restricted CD8 T cells.

Clinical Experience With a Multidisciplinary Model of Vascular Ultrasound for the Evaluation for Giant Cell Arteritis.

Objective: Vascular ultrasound (VUS) is a first-line test for giant cell arteritis (GCA) in Europe but has been of limited use in the United States. We report clinical experience with a multidisciplinary model of VUS for the evaluation of GCA at a large US medical center.

Methods: Patients who underwent VUS for evaluation of GCA between 2013 and 2017 were reviewed.

Follow-up vascular ultrasounds in patients with giant cell arteritis.

Objectives: Literature describing follow-up vascular ultrasound (VUS) in giant cell arteritis (GCA) is limited. We report our experience with follow-up VUS obtained in clinical care of patients with GCA.

Methods: We retrospectively identified GCA patients with an abnormal initial VUS, defined as circumferential hypoechoic wall thickening ("halo sign"), or circumferential hyperechoic wall thickening without evidence of arteriosclerosis or arteritis, who subsequently underwent follow-up VUS during 2013-2018.

Asthma, Chronic Obstructive Pulmonary Disease, and Subsequent Risk for Incident Rheumatoid Arthritis Among Women: A Prospective Cohort Study.

Objective: Inflamed airways are hypothesized to contribute to rheumatoid arthritis (RA) pathogenesis due to RA-related autoantibody production, and smoking is the strongest environmental RA risk factor. However, the role of chronic airway diseases in RA development is unclear. We undertook this study to investigate whether asthma and chronic obstructive pulmonary disease (COPD) were each associated with RA.

Elevated Anti-Citrullinated Protein Antibodies Prior to Rheumatoid Arthritis Diagnosis and Risks for Chronic Obstructive Pulmonary Disease or Asthma.

Objective: To investigate elevation of anti-citrullinated protein antibodies (ACPAs) before diagnosis of rheumatoid arthritis (RA) and risks for chronic obstructive pulmonary disease (COPD) or asthma.

Methods: We performed a matched cohort study nested within the Nurses' Health Studies among women who donated blood. Women with incident RA after blood draw (self-reported, then confirmed by medical records) were each matched to 3 controls by age, cohort, year, and menopausal factors.

Validation of claims-based algorithms for psoriatic arthritis.

Purpose: An increasing number of new medications are being developed and approved for psoriatic arthritis (PsA). To generate real-world evidence on comparative safety and effectiveness of these drugs, a claims-based algorithm that can accurately identify PsA is greatly needed.

Methods: To identify patients with PsA, we developed seven claims-based algorithms based on a combination of diagnosis codes and medication dispensing using the claims data from Medicare parts A/B/D linked to electronic medical records (2012-2014).

Disease heterogeneity in antineutrophil cytoplasmic antibody-associated vasculitis: implications for therapeutic approaches.

In recent decades, antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis has transformed from an almost uniformly fatal disease to a treatable form of primary systemic vasculitis. Substantial disease heterogeneity exists within ANCA-associated vasculitis and the increasing understanding of this heterogeneity has implications for guiding treatment decisions. Approaches to induction and maintenance therapy vary depending on disease severity, clinical manifestations, and patient-specific factors.

Obstructive lung diseases and risk of rheumatoid arthritis.

: Smoking is an established risk factor for both lung diseases and rheumatoid arthritis (RA). Chronic mucosal airway inflammation may result in immune tolerance loss, neoantigen formation, and production of RA-related autoantibodies that increase the subsequent risk of RA. In this review, we aimed to summarize the current evidence supporting the role of obstructive lung diseases and subsequent risk of RA.

Asthma and elevation of anti-citrullinated protein antibodies prior to the onset of rheumatoid arthritis.

Background: Anti-citrullinated protein antibodies (ACPA) are central to rheumatoid arthritis (RA) pathogenesis and may develop at inflamed mucosa. We investigated whether asthma, a disease of airway mucosal inflammation, was associated with elevated ACPA before RA diagnosis.

Methods: We performed a nested case-control study among women in two prospective cohorts, the Nurses' Health Study (NHS; 1976-2014) and NHSII (1989-2015).

A live-attenuated RhCMV/SIV vaccine shows long-term efficacy against heterologous SIV challenge.

Previous studies have established that strain 68-1-derived rhesus cytomegalovirus (RhCMV) vectors expressing simian immunodeficiency virus (SIV) proteins (RhCMV/SIV) are able to elicit and maintain cellular immune responses that provide protection against mucosal challenge of highly pathogenic SIV in rhesus monkeys (RMs). However, these efficacious RhCMV/SIV vectors were replication and spread competent and therefore have the potential to cause disease in immunocompromised subjects. To develop a safer CMV-based vaccine for clinical use, we attenuated 68-1 RhCMV/SIV vectors by deletion of the Rh110 gene encoding the pp71 tegument protein (ΔRh110), allowing for suppression of lytic gene expression.

Enhancing safety of cytomegalovirus-based vaccine vectors by engaging host intrinsic immunity.

Rhesus cytomegalovirus (RhCMV)-based vaccines maintain effector memory T cell responses (T) that protect ~50% of rhesus monkeys (RMs) challenged with simian immunodeficiency virus (SIV). Because human CMV (HCMV) causes disease in immunodeficient subjects, clinical translation will depend upon attenuation strategies that reduce pathogenic potential without sacrificing CMV's unique immunological properties. We demonstrate that "intrinsic" immunity can be used to attenuate strain 68-1 RhCMV vectors without impairment of immunogenicity.
