https://acrabstracts.org/abstract/gout-as-an-immune-related-adverse-event-from-immune-checkpoint-inhibitors/
Kevin Lee, Carrie Ye2 and Shokrollah Elahi, Internal Medicine et. al.

Nov 9th, 2020 - Background/Purpose: Immune checkpoint inhibitors (ICI) are novel treatments approved for various tumours including melanoma, lung and kidney. By interacting with immunoregulatory molecules (programmed death-1 (PD-1), PD-1 ligand (PD-L1), or cytotoxic T-lymphocyte associated protein (CTLA-4)), ICI prevent inhibition of T-cells and thereby increase immune activity. However, this T-cell activation...

https://acrabstracts.org/abstract/management-of-gout-with-pegloticase-real-world-utilization-and-outcomes-from-trio-health-and-the-american-rheumatology-network-arn/
Nehad Soloman, Mona Amin, Kimmi Cox et. al.

Nov 9th, 2020 - Background/Purpose: Infusion reactions and other adverse events associated with pegloticase may lead to discontinuation of treatment in patient populations that have already failed or are intolerant to other uric acid lowering therapies (ULTs). Maximizing the benefit of pegloticase is critical in the absence of other suitable ULTs. Here, we examine use of pegloticase for patients in US clinical...

Management of Gout After Pegloticase; Observations of US Clinical Practice from Trio Health and the American Rheumatology Network (ARN)
https://acrabstracts.org/abstract/management-of-gout-after-pegloticase-observations-of-us-clinical-practice-from-trio-health-and-the-american-rheumatology-network-arn/
Nehad Soloman, Mona Amin, Simon Helfgott et. al.

Nov 9th, 2020 - Background/Purpose: Pegloticase is approved for severe gout in patients that are intolerant to, or whose disease is ineffectively controlled by, other uric acid lowering therapies (ULTs). The positioning of pegloticase as the last therapeutic option begs the question, how is gout managed once pegloticase is discontinued? Here we examine treatment following pegloticase for patients in US clinica...

https://acrabstracts.org/abstract/multimorbidity-in-rheumatoid-arthritis-psoriatic-arthritis-gout-and-osteoarthritis-within-the-rheumatology-informatics-system-for-effectiveness-rise-registry/
Bryant England, Huifeng Yun, Lang Chen et. al.

Nov 8th, 2020 - Background/Purpose: Rheumatic and musculoskeletal diseases (RMDs) often predispose the development of other chronic conditions, resulting in multimorbidity. While multimorbidity is increasingly being recognized and examined within individual RMDs, few studies have directly compared the burden and pattern of multimorbidity across RMDs. Therefore, we aimed to compare multimorbidity between rheuma...

Changes in Serum Urate, in the First 6-months of Initiation or Change of Urate-Lowering Therapy, Associate with Immediate Health-Related Quality of Life Outcomes in People with Gout
https://acrabstracts.org/abstract/changes-in-serum-urate-in-the-first-6-months-of-initiation-or-change-of-urate-lowering-therapy-associate-with-immediate-health-related-quality-of-life-outcomes-in-people-with-gout/
Ruth Topless, Tony Merriman, Siamak Noorbaloochi2 and Jasvinder Singh et. al.

Nov 7th, 2020 - Background/Purpose: Few studies, if any, have found association of the biochemical cause of gout (high serum urate) with functional limitation and health-related quality of life (HRQoL) and productivity decrements in gout. We examined the associations of changes in serum urate in the immediate term with HRQoL using data from five intervention clinical trials of urate-lowering therapies (ULT). M...

https://acrabstracts.org/abstract/gout-increases-length-of-stay-in-patients-hospitalized-for-heart-failure-exacerbation/
Daniel DeMizio, Guojing Wu, Ying Wei et. al.

Nov 7th, 2020 - Background/Purpose: There is growing evidence that both the prevalence of gout and its burden on healthcare costs has increased over recent decades. It has been shown that hospitalization increases the risk of acute gout flare, which may prolong hospital stay compared to those without gout flare. It is unclear whether patients with history of gout would have longer hospital stays in general, or...

Gout Management Beyond Prescription Writing: The Role of the Pharmacist
https://acrabstracts.org/abstract/gout-management-beyond-prescription-writing-the-role-of-the-pharmacist/
Emma Dorris, Paul Ryan, Mariosa Kieran et. al.

Nov 7th, 2020 - Background/Purpose: Urate lowering therapy (ULT) is recommended for long-term gout management. However, gout flares are common at the time of starting ULT, and these flares can impact on adherence to ULT. Co-prescription of low dose colchicine as anti-inflammatory prophylaxis is recommended for the first 6 months of ULT. Pharmacists play a key role in community gout education. We investigated p...
