Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The exposure is an attack of acute gout. Patients will randomised to receive anakinra plus allopurinol escalation therapy versus standard care alone. Standard care involves usual acute gout management (colchicine 500mcg daily for duration of flare) plus allopurinol escalation. Allopurinol dose will be increased according to published protocols starting at 50-100mg daily and increased 50-100mg every 2-4 weeks until target uric acid levels are achieved. Target uric level is either 0.30 or 0.36umol/L depending on patient factors (ACR 2020 and EULAR 2016 gout management guidelines). The dose of anakinra will be 100mg daily for 3 days administered subcutaneously and will be administered in clinic.

At baseline, all patients will undergo a Coronary CT Angiogram to assess for plaque burden in coronary arteries which will be repeated at 9 months. We undertake also patient questionnaires, metrology(swollen and tender joint count) and blood tests. The total duration of follow-up for each patient is 9 months.

Patients will be assessed monthly (initial and final visit may last one hour where as other visits approximately 20 mins)

Comparator / control treatment
The group will be observed prospectively. The anakinra group (100mg OD S/C for 3 days) will be compared against the group receiving usual care (comparator group).

In addition, the group receiving usual care alone will be split at the end of the study into a high risk cohort (those who experienced flares during titration of allopurinol therapy as part of usual care) versus low risk cohort (no flares).

Active

Eligibility
Key inclusion criteria
A diagnosis of gout according to 2015 ACR criteria and defined clinically as requiring initiation or currently on allopurinol therapy.
45 years and a minimum of 2 risk factors, i.e. controlled hypertension, controlled diabetes, controlled dyslipidemia, obesity, age >55 years, smoker <65 years and first degree relative with evidence of atherosclerosis <65 years will be recruited.

Statistical methods / analysis
No pilot data is available to power this study, so a pragmatic decision has been made to include 14 patients to generate pilot data, assuming 50% will flare on allopurinol initiation. Descriptive statistics (such as mean with standard deviations for continuous variables, frequencies with percentages for categorical variables) will be used to summarise the two study groups. The differences between the study groups will be compared using paired t-test for continuous variables and chi-square tests for categorical variables.

Two investigators will administer the medication and conduct safety assessments. One investigator will be assessing outcomes and will be blinded to the intervention.

Summary
Brief summary
This study aims to assess the cardiovascular risk in people with acute gout treated with anakinra through performing imaging the heart at baseline and at 9 months. We will determine the impact of having an acute flare of gout on the scans, which is a surrogate of cardiovascular risk. We will also determine the impact of a drug (anakinra), which is increasingly being used in acute gout, on its effect on these heart scans. This will help us understand the effect of acute inflammation on cardiovascular risk in gout.

The use of anakinra for acute gout will also be assessed in terms of its effectiveness, safety and tolerability.
