Abstract
The use of anti-TNFs in Crohn's disease (CD) is often associated with the appearance of antinuclear antibodies, and more rarely with anti-native DNA antibodies. Anti-TNF-induced lupus remains exceptional. We report the case of a 52-year-old woman, followed for colonic Crohn's disease, treated with Infliximab. After 12 months of treatment with anti-TNF alpha (Infliximab), the patient developed clinical and biological lupus with positive antinuclear antibodies (ANA) and anti-native DNA antibodies (IgG). Infliximab treatment was discontinued. Six months after stopping the treatment, the patient had no recurrence of clinical signs, and immunological examinations showed a marked decrease in total ANA and anti-native DNA antibodies (IgG).
