Infantile acute liver failure in the West of Scotland.

Background: Our current understanding regarding the aetiology of infantile acute liver failure largely derives from studies conducted by regional liver units. This may introduce selection bias and therefore not provide a true reflection of the wider population.
Methods: Every coagulation screen with a prothrombin time ≥18 s in our centre was examined over one calendar year. All patients less than 1 year of age were included and their electronic records retrospectively reviewed.
Results: 24 patients were identified, from 9989 coagulation screens, that fit the current definition of acute liver failure. Hypoxic birth injury and ischaemic events were the most common aetiologies. Survival was 75%.
Conclusion: The 'catch-all' methodology employed demonstrated that acute liver failure is more common than previously reported and suggests that current data may exclude large numbers who either have more minor self-resolving disease or conversely have severe disease leading to death prior to transfer.
