Natalie McCormick, Zachary Wallace, Chio Yokose et. al.

Nov 13th, 2019 - Background/Purpose: Gout affects >4 million US adults aged ≥ 65 years, but little is known about the scale and drivers of public spending on gout medications, including colchicine.  Used for decades, its price rose drastically after one brand-name form (Colcrys) was granted market exclusivity from 2011-2014, as part of the FDA Unapproved Drugs Initiative. We quantified changes in total spending...

Hemant Suryawanshi, Robert Clancy, Evan Der et. al.

Nov 13th, 2019 - Background/Purpose: The impact of renal injury in lupus nephritis (LN) is widespread with consequences to resident cells in other tissue beds, even non-lesional, non-sun exposed skin. Faithful reflection of a relevant renal tissue pathway in a more readily accessible compartment would allow for less invasive diagnostic alternatives. While ongoing studies are exploiting single cell RNA sequencin...

Nov 13th, 2019 - Background/Purpose: Cutaneous lupus erythematosus (CLE) is an autoimmune disease with various subsets and clinical manifestations. T lymphocytes are the predominant cell type found in lesional skin, but plasmacytoid dendritic cells (pDCs) and myeloid dendritic cells (mDCs) also play an important role in the pathogenesis. Oral antimalarials, including hydroxychloroquine (HCQ) and quinacrine (QC)...

Interferon Signature Predicts Response to Tofacitinib in Haploinsufficiency of A20
https://acrabstracts.org/abstract/interferon-signature-predicts-response-to-tofacitinib-in-haploinsufficiency-of-a20/
Sarah Blackstone, Daniella Schwartz, Natalia Sampaio Moura et. al.

Nov 13th, 2019 - Background/Purpose: The protein A20, encoded by TNFAIP3, represses signaling upstream of the inflammatory transcription factor nuclear factor (NF)-kB by regulating ubiquitination. Heterozygous loss-of-function mutations in TNFAIP3 cause the systemic autoinflammatory disease Haploinsufficiency of A20 (HA20) [1]. Because no FDA-approved medications directly target NF-kB signaling, current HA20 th...
