Carbon nanotubes and nanofibers exposure and sputum and blood biomarkers of early effect among U.S. workers

Carbon nanotubes and nanofibers are used in many fields, such as in manufacturing and information technology. Both of these carbon particles are physically similar to asbestos, and one type of carbon nanotube (MWCNT-7) have recently been found to be carcinogenic. Due to the variety of carbon nanotubes and nanofibers, accessing their potential toxicity to workers remains difficult. Animal studies have demonstrated that exposure to nanotubes and nanofibers can lead to oxidative stress and cardiovascular effects locally and systemically. This is the first industrywide cross-sectional study across 12 different sites in the United States. Of the 144 workers identified, 108 workers from 12 different companies provided blood and/or sputum samples. Using a custom biomarker panel, Myriad RBM analyzed collected sputum and blood samples for 30 and 31 biomarkers respectively. Primary pattern identification used exploratory factor analyses with varimax rotation.

Lower serum IgA is associated with COPD exacerbation risk in SPIROMICS

Lambert, Laura M. Paulin, Ashraf Fawzy, Richard E. Kanner, Robert Paine, III, MeiLan K. Han, Fernando J. Martinez, Russell P. Bowler, R. Graham Barr, Nadia N. Hansel, for the SPIROMICS investigators
Read Full Article » Chronic obstructive pulmonary disease (COPD) is a leading cause of death, not just in the US but also worldwide. Patients with COPD are at increased risk for various respiratory infections, which are main contributors to COPD exacerbations. Selective IgA deficiency is associated with higher risk of respiratory infections, however, a link between serum IgA levels and COPD disease activity has never been established. The goal of this study is to test the hypothesis that sub serum IgA levels is associated with increased morbidity in COPD patients, using participants from the SPIROMICS cohort. Serum was collected at enrollment, and IgA levels were measured using the Myriad RBM biomarker discovery platform. Deficient IgA was defined as <7mg/dL and subnormal level defined as ≤70mg/dL. Follow-up was conducted yearly at the clinic and quarterly by phone for up to 3 years.

Rheumatology 2018 Read Full Article » Blau syndrome is an inherited auto-inflammatory disease that is characterized by arthritis, dermatitis, and uveitis. Patients also experience the presence of non-caseating granulomas, suggesting that the disease pathogenesis involves activated macrophages. The current management of Blau disease, using familiar drug classes such as corticosteroids, DMARDS and biologics, is not adequate. In order to assist in future drug development studies, biomarkers for Blau disease activity will be extremely useful. Phagocyte specific S100 proteins, such as S100A12, S100A8, and S100A9, have been proposed as biomarkers for Blau syndrome. These proteins are secreted by neutrophils and macrophages upon activation. This prospective cohort study will aim to correlate disease activity with inflammatory and S100 proteins.

Effects of Canagliflozin Versus Glimepiride on Adipokines and Inflammatory Biomarkers in Type 2 Diabetes

Timothy Garvey, Luc Van Gaal, Lawrence A. Leiter, Ujjwala Vijapurkar, James List, Robert Cuddihy, Jimmy Ren, Michael J. Davies
Metabolism. 2018. doi: 10.1016/j.metabol.2018.02.002 Type 2 diabetic patients with increased visceral fat mass and insulin resistance are at a higher risk for cardiovascular disease and premature death. The increased visceral fat impairs adipose tissue function and is the result of combinatorial processes, including increased macrophage recruitment (MCP-1 production), increased inflammatory cytokines (IL-6 and TNF-a secretion), and reduced anti-inflammatory factors (adipokine and adiponectin).

Myriad RBM Announces an Agreement with Sanofi to Measure Predictive Cardiovascular Biomarkers in Patients with Diabetes

SALT LAKE CITY, Utah, Oct. 25, 2016 – Myriad RBM, a wholly-owned subsidiary of Myriad Genetics, Inc. (NASDAQ: MYGN), today announced that it will work with Sanofi, a global and diversified healthcare leader, to perform a biomarker analysis of blood samples from the Evaluation of Lixisenatide in Acute Coronary Syndrome (ELIXA) trial (NCT01147250).
“We know that cardiovascular risk is higher in people with diabetes and that cardiovascular disease negatively affects treatment outcomes,” said Riccardo Perfetti, head of Global Diabetes Medical Team, Sanofi. “Sanofi is committed to further exploring cardiovascular disease in this patient population. The biomarker work with Myriad RBM will allow us to further develop a molecular understanding of the cardiovascular risks in people with type 2 diabetes. Biomarker profiling supports our goal of developing potentially innovative new treatments for patients.”

IL-10 (AM0010) phase I trial offers novel mechanism for immune-oncology drugs in solid tumors

More commonly known as an inhibitory cytokine, high doses of interleukin 10 (IL-10) have been shown to lead to the activation and survival of antigen stimulated CD8 T cells. According to a study published in the Journal of Clinical Oncology, the investigators in this first-in-human, phase 1 clinical trial of IL-10 (AM0010), demonstrate antitumor activity and therapy tolerability in a pretreated population.  The primary endpoint of the study was to establish safety, tolerability and the maximum tolerated dose.  This goal appears to have been met, with a low incidence of adverse events, most of which were temporary or reversible.  The dose-escalation study was followed by a renal cell cancer dose-expansion cohort.
