Helicobacter pylori seroprevalence in children with sleep-disordered breathing.

Objective: Chronic Helicobacter pylori (HP) infection is considered to be a factor involved in obstructive sleep apnea syndrome (OSAS). This cross-sectional study examined the seroprevalence of HP in children with sleep-disordered breathing (SDB) in respect to OSAS severity and in reference to other common pediatric medical conditions.

Methods: Overnight polysomnography with pH-metry (PSG) was performed at a Sleep Laboratory (in the years 2008-2011).
