Risk of Gout Onset and Flare Linked to Urate Levels

Serum uric acid (SUA) levels are clearly linked to gout. Researchers from Harvard have systemically reviewed the literature to quantify the risk of onset and flare with varying levels of SUA.

Literature review identified 8 eligible articles reporting gout incidence and 18 articles reporting recurrent gout rates in the context of SUA levels.

Gout incidence rates per 1000 person-years from population-based studies ranged from 0.8 (SUA ≤ 6 mg/dl) to 70.2 cases (SUA ≥ 10 mg/dl).

Recurrent gout risk in clinical cohorts ranged from 12% (SUA ≤ 6 mg/dl) to 61% (SUA ≥ 9 mg/dl) among those receiving urate-lowering therapy (ULT), and for those controlled with successful ULT, flare/recurrence rates ranged from 3.7% (SUA 6-7 mg/dl) to 61% (SUA > 9.3 mg/dl).

These data on the risks of higher SUA levels and gout underscores the need to treat to SUA targets as recommended by the American College of Rheumatology and the European League Against Rheumatism.

T2T Lowers Mortality in Gout

A Spanish prospective cohort of active, uncontrolled gout patients were followed and showed that failure to reach a target serum uric acid (sUA) level of 6 mg/dl (0.36 mmol/L) or less was associated with a 2-3 fold increase in mortality.

Novel Inhibition of MSU Crystal Inflammation

Researchers from Washington State University have shown that inhibition of tumor growth factor-β (TGF-β)-activated kinase 1 (TAK1) can effectively downregulate inflammatory mediators and suppress inflammation caused by gout.

Monosodium urate (MSU) crystals directly activate the inflammasome to produce a plethora of pro-inflammatory cytokines, including interleukin-1β (IL-1β). 

Patients Prefer Nurse Led Care for their Gout

Despite the well known, well publicized treat-to-target (T2T) goal of a serum uric acid (SUA) level < 6 mg/dl, this goal is seldom achieved (< 40%) in clinical practice and patient adherence has been unacceptably low. A recent study shows that nurse-led care led to better outcomes in gout including patient acceptability, long-term adherence, and less flares.

Anakinra Use in Hospitalized Gout Patients

While the efficacy and safety of interleukin 1 (IL-1) inhibitors (e.g., anakinra) in the acute management of gout and pseudogout has been repeatedly shown, the cost efficacy of such biologic therapy has rendered it impractical for most. A new retrospective study has shown that IL-1 inhibitors may be effective and appropriate for some medically complex, hospitalized patients with acute gout or calcium pyrophosphate crystal arthritis.

Higher Rates of Venous Thromboembolism in Gout

A Canadian administrative claims analysis has shown that gout-associated inflammation increases the risk of venous thromboembolism (VTE), deep vein thrombosis (DVT), and pulmonary embolism (PE) before and after the diagnosis of gout.
