Mother to child transmission of anti- S cerevisiae mannan antibodies (ASCA) in non-IBD families
Statistics from Altmetric.com
Editor,—We enjoyed the recent study by Sutton and colleagues (Gut2000;46:58–63) which confirmed our previous findings that elevated anti-S cerevisiaemannan antibodies (ASCA) are a familial trait in Crohn's disease.1 The lack of concordance in marital pairs indicated that familiality may be due to either a genetic factor or childhood environmental exposure. ASCA are present in 50–60% of patients with Crohn's disease, in 10–15% of patients with ulcerative colitis, and in 2–5% of control subjects.2-5 To gain more information on concordance for ASCA among family members, we studied ASCA distribution in non-inflammatory bowel disease (IBD) families.
