Methotrexate may provide benefits in treatment of the chronic arthritis that can persist following acute chikungunya virus infection, but definitive evidence remains lacking, researchers reported.

Researchers from Hong Kong assessed the clinical associations seen with the anti-melanoma differentiation-associated gene 5 antibody (anti-MDA5 Ab) assay in consecutive patients with dermatomyositis (DM) and polymyositis (PM).

The ACIP has discussed and analyzed its VZV vaccination policy to ensure safety and reduce disease burden. This report serves as a supplement to the 2008 Prevention of Herpes Zoster Recommendations.

In the past 2 decades, mortality from end-stage renal disease (ESRD) among U.S. patients with granulomatosis with polyangiitis (GPA) has declined significantly, a nationwide study found.

Like their adult counterparts, psoriasis in children is an independent risk factor for comorbidity, but not as much as  obesity.

An observational study of patients with active rheumatoid arthritis (RA) or spondyloarthritis (SpA) experiencing secondary failure to TNF inhibitor (TNFi) therapy showed that (secondary) loss of efficacy to a TNFi was associated with anti-drug antibodies in less than 30% of patients. 

Is your patient’s refrigerator the problem with the inefficacy of biologic therapies? Studies show most patients don't store their biologics correctly, which may be a source of limited drug efficacy.

A report from Annals of Rheumatic Diseases suggests that osteoarthritis (OA) may be two distinct diseases based on genetic studies of articular cartilage. (Citation source: https://buff.ly/2mNtUsL).

Since 2000, the German Biologics register (BiKeR) has prospectively enrolled children with juvenile idiopathic arthritis to assess outcomes with biologic therapies.  A new report evaluates the efficacy and safety of etanercept (ETA), tocilizumab (TOC) and the interleukin-1 inhibitors (anakin

A study from Nature Neuroscience shows that a high salt diet may mediate neurovascular disease by altering microbiome and the expansion of TH17 cells in the small intestine, thereby increasing plasma interleukin-17 (IL-17) and its subsequent effects on endothelium in the brain.

The most common cerebrovascular events (CVEs) seen among a large cohort of patients with systemic lupus erythematosus (SLE) were stroke and transient ischemia, and the majority of these events were attributable to the disease itself, a multinational study determined.

The Journal of Clinical Investigation reports results of a study showing that increases in CD21lo B cells and plasmablasts following that combination checkpoint blockade preceded the onset of immune-related adverse events.

While some have postulated that IRAEs are thought to be T cell mediated, B cells have also been implicated. Investigators studied 39 melanoma patients undergoing treatment with either anti-CTLA4 or anti-PD1, or combination CCB therapy. They analyzed changes in circulating B cells before and after the first cycle of therapy of immune checkpoint blockade (23 received combination therapy, 8 received anti-CTLA4, and 8 received anti-PD1).

PNAS reports use of ibuprofen by males may result in antiandrogen effects that may contribute to adult male reproductive problems.

Myeloablative autologous stem cell transplantation was significantly more effective than 12 months of cyclophosphamide among patients with severe scleroderma, an open-label multicenter study found.

Despite large randomized trials failing to show the efficacy of RTX in SLE (LUNAR, EXPLORER), uncontrolled observational data suggests possible efficacy and safety of RTX in refractory SLE.

The Food and Drug Administration (FDA) approved use of Nucala (mepolizumab) for use in treating adults with eosinophilic granulomatosis with polyangiitis (EGPA), previously known as Churg-Strauss vasculitis. This is first FDA-approved therapy specifically to treat EGPA. 

The NLRP3 inflammasome is a critical component of the innate immune system and activation of NLRP3 inflammasome results in caspase-1–dependent secretion of the proinflammatory cytokines IL-1β and IL-18.

Dr. Jack Cush covers the news and journal articles published on RheumNow.comin the past week.

Even though Arkansas lies on the edge of the geographic range of the principal Lyme disease tick vector, Ixodes scapularis, the risk for Lyme infection is low, and no confirmed Lyme disease cases were reported in Arkansas during 2008–2014 (1)
