In the last few years many studies have shown the potential role of different triggers in the pathogenesis of several autoimmune diseases. In particular, in Sjogren's syndrome the presence of a genetic background is considered determining, but environmental factors have recently been described as triggers or precipitators. In this report, we describe the case of a young woman affected by celiac disease in which an Ascaris lumbricoides infestation and estrogen therapy could have played a role in the development of Sjogren's syndrome.
