Non-axial bone fracture but not depression as a risk factor for coeliac disease

Screening for coeliac disease is confined to subgroups at greater risk for the disease, including type 1 diabetes mellitus, autoimmune thyroid disease and family members of affected individuals. This study examined the hypothesis that patients taking antidepressants or presenting with fractures could represent new subgroups at higher risk for coeliac disease. A total of 105 and 199 consecutive patients presenting to hospital taking antidepressants and/or with a fracture was screened with IgA tissue transglutaminase and had their IgA serum levels quantified. Patients with positive serology were offered further diagnostic and management follow up. No patients taking antidepressants had positive serology. Seven with fractures had elevated titres of IgA tissue transglutaminase. All of these patients had presented with non-axial fractures, representing a prevalence of 5.2% (95% confidence interval: 1.4-8.9%). Uptake of further investigation and management was poor. Patients presenting with non-axial fractures may be a subgroup in whom coeliac screening may be indicated. There needs to be greater awareness of atypical presentations of coeliac disease.
