Plain English Summary
Background and study aims
Gout is the most common cause of inflamed joints, affecting 1.4% of adults in the UK. Most patients are treated entirely in general practice yet it is frequently not enough. Acute attacks of gout are excruciatingly painful and require urgent drug treatment to reduce inflammation, most commonly with non-steroidal anti-inflammatory drugs (NSAIDs) or colchicine. In GP surgeries, NSAIDs are most commonly used but can cause serious side effects such as stomach ulcers and heart disease, particularly in the elderly. Patients frequently require repeat prescriptions for recurrent attacks of acute gout, increasing the risk of drug-related side-effects. Low-dose colchicine is popular amongst rheumatologists as it is effective and well-tolerated. However, general practitioners (GPs) seldom prescribe colchicine, probably because in the past the recommendation was for high doses to be prescribed, which commonly caused severe diarrhoea. Recently, prescribing recommendations for colchicine have changed, advocating a lower-dose regime. Currently there is no evidence regarding whether NSAIDs or low-dose colchicine is the best treatment for acute gout. This study is the first direct comparison of the effectiveness and side-effects of a NSAID (naproxen) and low-dose colchicine to treat acute gout in GP surgeries.
Who can participate?
Patients aged 18 and over consulting their GP, in participating GP practices, with an acute attack of gout
What does the study involve?
Participants are randomly allocated to receive either low-dose colchicine or Naproxen. Treatment success is assessed by comparing pain reduction between the two drugs using follow-up questionnaires. The study also monitors side-effects, quality of life and cost effectiveness.
What are the possible benefits and risks of participating?
Although there is no expected direct benefit for the patient, it is hoped that the study will improve the understanding of how to treat patients with gout in the future. The study is considered to pose no additional risks to participants than normal care for gout.
Where is the study run from?
The study is run from up to 100 general practices across England.
When is the study starting and how long is it expected to run for?
January 2014 to March 2016
Who is funding the study?
National Institute for Health Research (NIHR) School for Primary Care Research (UK)

Topic: Primary Care Research Network for England; Subtopic: Not Assigned; Disease: All Diseases
Participants will be randomised on a 1:1 basis to low-dose colchicine (500 mcg orally every eight hours for four days) or Naproxen (Single initial dose of 750 mg followed by 250 mg orally every eight hours for up to seven days). Participants will be followed up for 4 weeks.
Primary outcome measure
Pain intensity, measured on a 0-10 pain intensity numeric rating scale over days 0-7
Secondary outcome measures
1. Adherence to trial treatment, measured using patient self report; Timepoint(s): days 1-7
2. Quality of life, measured using EQ-5D 5-L; Timepoint(s): day 7 and 4 weeks
3. Healthcare utilisation (re-attendance at GP/accident and emergency/primary care out-of-hours service), measured using patient self report; Timepoint(s): 4 weeks
4. Patient global assessment of response to treatment, measured using patient self report; Timepoint(s): day 7 and 4 weeks
5. Relapse/recurrence of acute gout, measured using patient self report; Timepoint(s): 4 weeks
6. Side-effects (e.g. nausea, vomiting, dyspepsia, diarrhoea and abdominal pain), measured using a self-reported questionnaire; Timepoint(s): days 1-7, 4 weeks
7. Time off work/education, measured using patient self report; Timepoint(s): 4 weeks
8. Use of other medications for pain relief (e.g. steroids, paracetamol, opiates), measured using patient self report; Timepoint(s): days 1 - 7 and 4 weeks
