Abstract
Our aim was to review our experience of trientine as chelation therapy in children with Wilson disease (WD) and compare to that reported in the literature. We made a retrospective review of the medical notes of 16 of 96 (17%) children diagnosed with WD between 1981 and 2006. Children were 6.6 to 15 years old. Only three received trientine as initial therapy [parental choice (two), allergic reactions to penicillamine (one) during the penicillamine challenge], 13 of 16 were converted from penicillamine to trientine because of reactions to penicillamine: haematuria in four, bone marrow suppression in three, neutropenia in three. Trientine was discontinued in three due to allergic rash, low copper excretion and one with compliance problems requiring transplantation. Seventy-five per cent of children presented with chronic liver disease. Kayser–Fleischer rings were noticed in eight of 16, Wilson Ferenci score range was between 4 and 10 (nl < 4). Laboratory indices remained relatively stable. In line with previous reports, trientine was used mainly as secondary treatment when there were severe side effects with penicillamine. Whilst the current evidence is low quality, it appears that trientine is as efficacious as penicillamine and small population studies show a lower side effect profile.
