Leptin and adiponectin are adipokines that have been found to be associated with several malignancies but the relationship with Barrett’s oesophagus, the precursor of the majority of oesophageal adenocarcinomas, is unknown. In this Australian study, this relationship was investigated. There was a significant, three-fold increased risk of Barrett’s oesophagus among men in the highest quartile of serum leptin (see table) and this persisted after adjustment for reflux symptoms. On the contrary, a tendency towards decreased risk for Barrett’s oesophagus among women with increasing leptin levels was observed. No association with adiponectin was seen. Kendall et al conclude that there is an association between leptin and the presence of Barrett’s oesophagus in men—but not in women—and that this association is not explained . . .
