To assess the seroprevalence of Helicobacter pylori (HP) in children with i
nsulin dependent diabetes mellitus, a serological test for Helicobacter pyl
ori (anti-HP IgG with ELISA) was performed in 88 diabetic and 42 healthy co
ntrol children. Anti-HP IgG was positive in 49/88 (55.6%) of diabetics and
13/42 (30.9%) of controls (p<0.01). Diabetic children were divided into two
groups according to HP status: HP(+) and HP(-). The two groups were compar
ed for age, gender, duration of diabetes, diabetic control (HbA(1c)), SDS f
or height and gastric emptying time. Seroprevalence of HP was higher in IDD
M patients than in healthy controls. Duration of diabetes was the only fact
or which correlated significantly with HP status. HP status was not related
to gastric emptying time.
