Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will undergo 4-weekly venesection of 1 unit (400-500mL) of blood in the outpatient pathology centre, with experienced nursing staff performing venipuncture. Each venesection takes between 15-30 minutes. Up to a maximum of 10 venesections will be performed, with patients not undergoing their next scheduled venesection if they develop anaemia (Hb <120 g/L for women, Hb <130 g/L for men) or de-iron to a serum ferritin <200 micrograms/L. Patients who achieve a serum ferritin <200 micrograms/L prior to 10 venesections will remain in the study and continue to have 4-weekly blood tests, recommencing venesection if ferritin rises above 200 micrograms/L within 8 weeks of last venesection and if within 10 months of first venesection. The maximum total duration of the intervention is 12 months. Adherence to venesection will be monitored through view of planned blood tests on the same day as scheduled venesection.

All patients will be provided with identical dietary advice and exercise advice for non-alcoholic fatty liver disease as per standard of care (this will be recommendations to reduce simple carbohydrates and saturated fats, with advice to follow the Mediterranean diet; and recommendation to undergo 30 minutes of exercise of at least moderate intensity 4-5 days per week). This advice will be provided verbally.

Efficacy
Statistical methods / analysis
Given this is a pilot study, only small numbers (15 patients) are planned for enrolment to investigate whether venesection in this population reduces histological iron staining. As this is a pilot study aimed at obtaining preliminary data that can be utilized to plan for a larger study, no power calculation has been conducted. Statistical analysis of paired results (at enrolment, at completion of study intervention) for each patient will be undertaken.
