The results of a unique dietary supplement (nutraceutical formulation) used to treat the symptoms of long-haul COVID.

Long-COVID is a syndrome characterized by debilitating symptoms that persist over 3 months after infection with the SARS-CoV-2 virus. It affects 15 to 33% of COVID-19 recovered patients and has no dedicated treatment. First, we found that β-caryophyllene and pregnenolone have a significant synergistic effect in the resolution of LPS-induced sepsis and inflammation in mice.

Reduced Cell Surface Levels of C-C Chemokine Receptor 5 and Immunosuppression in Long Coronavirus Disease 2019 Syndrome.

In an exploratory trial treating "long COVID" with the CCR5-binding antibody leronlimab, we observed significantly increased blood cell surface CCR5 in treated symptomatic responders but not in nonresponders or placebo-treated participants. These findings suggest an unexpected mechanism of abnormal immune downmodulation in some persons that is normalized by leronlimab. Clinical Trials Registration.

Switching to Biosimilar SDZ-ADL in Patients with Moderate-to-Severe Active Rheumatoid Arthritis: 48-Week Efficacy, Safety and Immunogenicity Results From the Phase III, Randomized, Double-Blind ADMYRA Study.

Background: Sandoz adalimumab SDZ-ADL (GP-2017) is an approved adalimumab biosimilar with similar efficacy and comparable safety and immunogenicity to reference adalimumab (ref-ADL) as confirmed by analytical, pharmacokinetic and confirmatory studies. ADMYRA, a phase III double-blind study, was conducted with an aim to generate efficacy, safety and immunogenicity comparability data in patients with moderate-to-severe rheumatoid arthritis (RA) having inadequate response to disease-modifying anti-rheumatic drugs (DMARDs) including methotrexate (MTX). The study also evaluated an aspect of 'switching' reference product to the biosimilar in terms of efficacy, safety and immunogenicity up to Week 48.

Safety and efficacy of neurostimulation with a miniaturised vagus nerve stimulation device in patients with multidrug-refractory rheumatoid arthritis: a two-stage multicentre, randomised pilot study.

Unlabelled: Background The inflammatory reflex plays a role in regulating innate and adaptive immunity by modulating cellular and molecular inflammatory pathways. The vagus nerve is a major constituent of the inflammatory reflex and studies have shown that the reflex can be activated by electrical stimulation of the vagus nerve. In this first in-human pilot study, we assessed the safety and efficacy of a novel miniaturised vagus nerve stimulation (VNS) device for the treatment of multidrug-refractory rheumatoid arthritis.

Patient Perspectives on Intravenous Biologics for Rheumatologic Disease.

Objective: Two surveys were conducted with patients with rheumatologic diseases to evaluate perceptions of different routes of administration (intravenous [IV] or subcutaneous [SC]) for biologic therapy.

Methods: In Survey I, patient preferences toward biologic treatment were evaluated at a rheumatology practice in Buffalo, New York. In Survey II, Canadian patients enrolled in the BioAdvance patient support program and scheduled to receive IV biologic therapy were asked about their opinions of IV treatment.

Patient-reported outcome assessment of inflammatory arthritis patient experience with intravenously administered biologic therapy.

Objective: To evaluate patient perspectives regarding utilization of intravenous (IV) therapy for inflammatory arthritis (IA).

Methods: This was a single-center, noninterventional, patient questionnaire-based study of adult IA patients currently receiving IV biologics. At a single visit, patients completed the questionnaire comprising 30 questions centered on their experience receiving an intravenously administered therapy to treat their IA.

Proceedings from the 7th Annual International Society for Musculoskeletal Imaging in Rheumatology (ISEMIR) conference.

The International Society for Musculoskeletal Imaging in Rheumatology (ISEMIR) was founded in 2005 with the goal of discussing matters related to imaging in rheumatology, particularly, validation, education, and use in clinical practice and research. Because the field of musculoskeletal (MSK) imaging is rapidly evolving, continuous education in the field is imperative. ISEMIR's international faculty and world-renowned experts presented the newest information as it relates to the use of magnetic resonance imaging (MRI) and ultrasound (US) at the 7th annual ISEMIR meeting which took place on April 12-14, 2014 in Santa Monica, California.

Golimumab in patients with active rheumatoid arthritis after treatment with tumor necrosis factor α inhibitors: findings with up to five years of treatment in the multicenter, randomized, double-blind, placebo-controlled, phase 3 GO-AFTER study.

Introduction: The aim of this study was to assess long-term golimumab therapy in rheumatoid arthritis (RA) patients who discontinued previous tumor necrosis factor-α (TNF)-inhibitor(s).

Methods: Patients enrolled into this multicenter, randomized, double-blind, placebo-controlled study of active RA (≥4 tender, ≥4 swollen joints) received placebo (Group 1) or golimumab 50 mg (Group 2) or 100 mg (Group 3) injections every 4 weeks. Patients in Groups 1 and 2 with inadequate response at week 16 escaped to golimumab 50 and 100 mg, respectively.

Safety of infusing rituximab at a more rapid rate in patients with rheumatoid arthritis: results from the RATE-RA study.

Background: As recommended in the current prescribing information, rituximab infusions in patients with rheumatoid arthritis (RA) take 4.25 hours for the first infusion and 3.25 hours for subsequent infusions, which is a burden on patients and the health care system.

Monitoring cartilage loss in the hands and wrists in rheumatoid arthritis with magnetic resonance imaging in a multi-center clinical trial: IMPRESS (NCT00425932).

Introduction: Magnetic resonance imaging (MRI) is increasingly being used in clinical trials of rheumatoid arthritis (RA) because of its superiority over x-ray radiography (XR) in detecting and monitoring change in bone erosion, osteitis and synovitis. However, in contrast to XR, the MRI scoring method that was used in most clinical trials did not include cartilage loss. This limitation has been an obstacle to accepting MRI as a potential alternative to XR in clinical trials.

Proceedings from the 5th Annual International Society for Musculoskeletal Imaging in Rheumatology Annual Conference.

Since its inception, ISEMIR has held an annual education meeting highlighting the changes in the utilization of imaging tools for the management of rheumatic diseases. ISEMIR's international faculty and world-renowned experts have discussed these topics at a very high scientific level. The evolution of the content demonstrates the rapidly changing environment in the field of rheumatology.

Evaluating joint-space narrowing and cartilage loss in rheumatoid arthritis by using MRI.

Introduction: Magnetic resonance imaging (MRI) has been shown to be superior to radiography (XR) for assessing synovitis, osteitis, and bone erosion in rheumatoid arthritis (RA), particularly in clinical trials. However, relatively little has been reported on the ability of MRI to evaluate articular cartilage loss, or joint-space narrowing (JSN), in the hands and wrists. In a previous study, we adapted the nine-point Genant-modified Sharp XR-JSN score for use with MRI (MRI-JSN).

Golimumab in patients with active rheumatoid arthritis who have previous experience with tumour necrosis factor inhibitors: results of a long-term extension of the randomised, double-blind, placebo-controlled GO-AFTER study through week 160.

Objective: The aim of this study was to assess long-term golimumab therapy in patients with rheumatoid arthritis (RA) who discontinued previous tumour necrosis factor alpha (TNFα) inhibitor(s) for any reason.

Methods: Results through week 24 of this multicentre, randomised, double-blind, placebo-controlled study of active RA (≥4 tender, ≥4 swollen joints) were previously reported. Patients received placebo (Group 1), 50 mg golimumab (Group 2) or 100 mg golimumab (Group 3) subcutaneous injections every 4 weeks.

Retreatment with rituximab based on a treatment-to-target approach provides better disease control than treatment as needed in patients with rheumatoid arthritis: a retrospective pooled analysis.

Objective: To assess the efficacy and safety profiles of two different rituximab retreatment regimens in patients with RA.

Methods: Four hundred and ninety-three RA patients with an inadequate response to MTX recruited into rituximab Phase II/III studies received further courses of open-label rituximab based on two approaches: (i) treatment to target (TT): patients assessed 24 weeks after each course and retreated if not in remission [DAS in 28 joints based on ESR (DAS-28-ESR) ≥ 2.6]; (ii) treatment as needed (PRN): patients retreated at the physician's discretion ≥24 weeks following the first course and ≥16 weeks following further courses, if both swollen and tender joint counts were ≥8.

Magnetic resonance imaging in rheumatoid arthritis clinical trials: emerging patterns based on recent experience.

Objective: The current validated magnetic resonance imaging (MRI) scoring method for rheumatoid arthritis (RA) in clinical trials, RA MRI Score (RAMRIS), incorporates all metacarpophalangeal (MCP) and wrist joints except MCP-1. The experience with radiographic scoring, however, was that excluding certain bones in the wrist improved the discriminative power for changes over time. In this study, we pool MRI data from randomized controlled clinical trails (RCT) to determine which combination of MCP and wrist joints are most sensitive and discriminative for structural changes over time.

Efficacy and safety of retreatment in patients with rheumatoid arthritis with previous inadequate response to tumor necrosis factor inhibitors: results from the SUNRISE trial.

Objective: To assess the efficacy and safety of 1 versus 2 courses of rituximab over 48 weeks in patients with rheumatoid arthritis (RA).

Methods: Adult patients taking methotrexate with a previous inadequate response to > or = 1 tumor necrosis factor inhibitor received 1 course of open-label rituximab (2 x 1000 mg IV) at baseline. From Week 24, patients were randomized to receive an additional course of retreatment with rituximab or placebo.

Golimumab in patients with active rheumatoid arthritis after treatment with tumour necrosis factor alpha inhibitors (GO-AFTER study): a multicentre, randomised, double-blind, placebo-controlled, phase III trial.

Background: Tumour necrosis factor alpha (TNFalpha) inhibitors are frequently used to treat rheumatoid arthritis, but whether use of a different TNFalpha inhibitor can improve patient response is unknown. We assess the efficacy and safety of the TNFalpha inhibitor golimumab in patients with active rheumatoid arthritis who had previously received one or more TNFalpha inhibitors.

Methods: 461 patients with active rheumatoid arthritis from 82 sites in 10 countries were randomly allocated by interactive voice response system, stratified by study site and methotrexate use, to receive subcutaneous injections of placebo (n=155), 50 mg golimumab (n=153), or 100 mg golimumab (n=153) every 4 weeks between Feb 21, 2006, and Sept 26, 2007.
