Despite Gout Numbers and Flares, Allopurinol is Underutilized

A population-based survey from South Australia shows that gout flares are common in the community and have a significant effect on health-related quality of life (HRQoL), yet there is significant undertreatment of gout, even in those on current allopurinol.

The South Australia Health Omnibus Survey is an annual, face-to-face adult population-based survey that collected information on self-reported medically diagnosed gout, allopurinol use and gout attacks (flares) in the prior 12 months.

Overall the findings showed:

  • the prevalence of gout in the population was 6.5%
  • 37.1% of gout patients were on current allopurinol and 23.2% reported prior use
  • frequent flares (≥ 2/year) were reported by 25% of gout
    • were more likely with: younger age, higher BMI, and current allopurinol use (p < 0.05)
    • in those with frequent gout flares, 51% were on current allopurinol therapy
  • gout flares were associated with a lower physical HRQoL (p = 0.012). 

Despite the prevalence, flares rates and HRQoL effects seen with gout, only 37% were on allopurinol (51% in those with frequent attacks).

Undertreated disease and suboptimal use of urate lowering therapy continue to plaque gout management in the populace.

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.

Modifiable Risk Factors for Hyperuricemia

Choi and colleagues have shown that four modifiable risk factors (BMI, the DASH diet, alcohol use, and diuretic use) could individually account for a notable proportion of observed hyperuricemia. 

Researchers examine modifiable risk factors for hyperuricemia and how this could be prevented through risk factor modification in the general population.

Opioids Overused in Acute Gout

Opioids were commonly given to patients as a treatment for acute gout attacks, despite the availability of other effective and appropriate therapies, a retrospective study found.

Allopurinol Fails to Curtail Hypertension

Editor's note: July 1 - 5, RheumNow is running the best of the EULAR 2019 meeting. A novel trial presented at EULAR 2019 last week assessed whether the use of urate-lowering therapy (ULT) would control hypertension in those at risk; however, results of this trial were largely negative.

Hypertension is one of the many comorbidities that plagues gout patients.
