title: Amoxycillin plus tinidazole for Campylobacter pylori gastritis in children: assessment by serum IgG antibody, pepsinogen I, and gastrin levels.
abstract: 32 children (mean age 12 years, range 6-18) with non-specific abdominal pain and Campylobacter pylori positive gastritis received a six week course of daily oral amoxycillin (50 mg/kg) and tinidazole (20 mg/kg). Before treatment and one month after stopping treatment, endoscopic biopsy samples were taken from the antral mucosa and serum C pylori IgG antibody, pepsinogen I, and gastrin levels were measured in fasting blood samples. One month after treatment 30 children (94%) were cleared of C pylori and gastritis had resolved in 27 (84%) and was improved in the remaining 5. Serum IgG, pepsinogen I, and gastrin levels were significantly decreased after treatment. Of 12 children assessed at six months, 9 remained free of C pylori. Increases or decreases in IgG level indicated clearance or recurrence, respectively, of C pylori.
