Macha's curse: an Ulster pedigree
Published online by Cambridge University Press: 13 June 2014
Abstract
Two individuals, a father and son with idiopathic intestinal pseudo-obstruction (IIPO), a familial visceral neuropathy, and major depressive illness are presented. In both the bowel symptoms preceded the onset of the depressive illness – the bowel symptoms presenting in mid-adolescence and the depressive illness presenting in middle age. Both patients required numerous laparotomies and both were treated with a series of ECTs. Both developed vitamin B12 deficiency anaemia and other evidence of malabsorption. At post-mortem both patients showed evidence of distension of the small bowel with volvulus. An extensive pedigree of both conditions overlapping in two inter-related families now extending to the fourth generation with 28 children under the age of 30 is described. Pending further investigation and genetic studies we postulate a possible common neurotransmitter pathology and recommend further neurochemical and histopathological studies of the myenteric plexus in IIPO. Furthermore, the genetic locus of familial IIPO might provide a genetic marker for some forms of primary affective disorder.
