Study ‘Offers the Kind of Evidence That We Need’
In an accompanying commentary, University of Alabama at Birmingham rheumatologist Angelo L. Gaffo, MD, MSPH, also noted that the study population was overwhelmingly White, had a low mean SU level (6.9 mg/dL), and had a low level of comorbidities, making the sample “poorly representative of the most commonly described gout populations.”
However, he also noted that there is “growing evidence linking serum urate levels with clinical outcomes,” with a pair of studies — one from 2021 and the other from 2022 — linking reductions in SU to < 6 md/dL to lower flare rates.

Dr. Gaffo told this news organization that although rheumatology guidelines support a treat-to-target strategy, “we haven›t generated a whole lot of important evidence to support it.”
The new study “offers the kind of evidence that we need,” he said, “but this is not going to be the ultimate answer.” That will only come from randomized clinical trials in the works that will pit the treat-to-target approach vs the primary care–favored strategy of titrating treatment until flares are controlled, he said.
Even though evidence is sparse, Dr. Gaffo said he still believes in the treat-to-target strategy: “I believe it is the best way to treat gout.”
What’s next? Researchers hope to understand how to better reach target SU goals in clinical practice, Dr. Choi said. “Involving nurses, pharmacists, or interactive online or app systems — as in other chronic treat-to-target care such as anticoagulation care, blood pressure, or lipid care — is actively being researched.”
He added that “we are trying to find the effective and safe medications and nonpharmacologic measures to reduce the urate burden, which can also simultaneously take care of gout’s frequent cardiovascular-kidney comorbidities.”
The US National Institutes of Health supported the study. Dr. Choi reports receiving grants from Horizon and serving on a board or committee for LG Chem, Shanton, and ANI Pharmaceuticals. Some other authors report an employment and stockholder relationship with Regeneron and support from the National Institute of Arthritis and Musculoskeletal and Skin Diseases, National Institutes of Health, and Rheumatology Research Foundation. Dr. Gaffo reports personal fees from PK MED, SOBI/Selecta, Atom, and UpToDate.
