Serum Interferon Predicts Lupus Flares
Elevated serum levels of interferon-α among patients whose systemic lupus erythematosus (SLE) was in remission helped predict future disease flares, European researchers found.

FUTURE 5 - Secukinumab and Less Radiographic Progression in Psoriatic Arthritis
The FUTURE 5 trial studied the effect of secukinumab (SEC) on radiographic progression through 52 weeks in patients with active psoriatic arthritis (PsA) and found that SEC was clinically and radiographically superior to placebo (PBO).
Patients received s.c. secukinumab 300 mg load (300 mg), 150 mg load (150 mg), 150 mg no load regimens or placebo at baseline, at weeks 1, 2 and 3 and every 4 weeks starting at week 4. The majority (87%) of patients enrolled at baseline remained in the study for 52 weeks.
Anakinra Use in Hospitalized Gout Patients
While the efficacy and safety of interleukin 1 (IL-1) inhibitors (e.g., anakinra) in the acute management of gout and pseudogout has been repeatedly shown, the cost efficacy of such biologic therapy has rendered it impractical for most. A new retrospective study has shown that IL-1 inhibitors may be effective and appropriate for some medically complex, hospitalized patients with acute gout or calcium pyrophosphate crystal arthritis.

Low Dose IL-2 Effective in Lupus
A double-blind, placebo-controlled clinical trial of low-dose IL-2 in patients with systemic lupus erythematosus (SLE) has shown that low-dose IL-2 induced was clinically effective while expandng regulatory T cells and NK cells, which may benefit immune homeostasis in SLE patients.
Anakinra Shows Benefits in Cytokine Storm
The interleukin (IL)-1 receptor antagonist anakinra (Kineret) showed promise in critically ill children who develop the often-lethal condition known as secondary hemophagocytic lymphohistiocytosis (sHLH)/macrophage activation syndrome (MAS), a retrospective single-center study found.

Bimekizumab Add-on Therapy in Rheumatoid Arthritis
Bimekizumab is a dual inhibitor of IL-17A and IL-17F that has been shown to be effective in psoriasis and psoriatic arthritis. A proof-of-concept study shows that giving bimekizumab to rheumatoid arthritis patients not adequately controlled by certolizumab pegol resulted in a rapid decrease in disease activity achieved after 12 weeks of treatment. These findings are novel as anti-IL-17 monoclonal antibody therapy has previously been shown to be ineffective in RA.

Autoantibodies Don't Disappear With Remission in RA
Immunologic remission in rheumatoid arthritis, defined as the disappearance of anti-citrullinated protein antibodies and rheumatoid factor, was seen infrequently among patients achieving sustained clinical remission and did not correlate with the disappearance of symptoms, a long-term Dutch study found.

Updated CDC Recommendation for Serologic Diagnosis of Lyme Disease
Serologic testing is the principal means of laboratory diagnosis of Lyme disease. Current recommendations include using a sensitive enzyme immunoassay (EIA) or immunofluorescence assay, followed by a western immunoblot assay for specimens yielding positive or equivocal results.
On July 29, 2019, the Food and Drug Administration cleared several Lyme disease serologic assays with new indications for use, allowing for an EIA rather than western immunoblot assay as the second test in a Lyme disease testing algorithm. Thus, serologic assays that utilize a second EIA in place of western immunoblot assay are acceptable alternatives for the serologic diagnosis of Lyme disease.
RA Disease Activity Drives Lung Complications
A longitudinal study from the BRASS registry shows that increase rheumatoid arthritis disease activity increases the risk of RA-associated interstitial lung disease (RA-ILD).
RA patients without RA-ILD at baseline, enrolled in the Brigham RA Sequential Study (BRASS, 2003–2016), were followed from 2003-2016 with serial clinical, DAS28, serologic and imaging assessments.
Periodontal Disease and P. gingivalis Increased in CCP+ Pre-Clinical RA
A cross-sectional study 48 CCP–positive "at risk" individuals (without arthritis) were shown to have an increased prevalence of periodontitis and P gingivalis when compared to 26 early RA (ERA) and 32 controls.

A Potential Biomarker for Chronic Fatigue Syndrome Patients
Myalgic encephalomyelitis/chronic fatigue syndrome affects at least 2 million people in the United States and bears tremendous overlap with fibromyalgia - both being difficult to diagnosis because the symptom complex is often unrecognized and these conditions have no biomarker test.

Borrelia burgdorferi Peptidoglycan Shedding Drives Lyme Arthritis
Research published in PNAS has shown that long after active Lyme infection in the joint, a peptidoglycan (PG) of the the spirochete Borrelia burgdorferi can be found in the joints of those with late-stage Lyme disease.
