ABSTRACT
<p><b>OBJECTIVE</b>To investigate the resistance of Helicobacter pylori (H. pylori) to antimicrobial agents in adolescents.</p><p><b>METHODS</b>One hundred and eight adolescents (6-18 years old) underwent a gastroscopy examination. H. pylori strains were isolated from gastric mucosa. Antimicrobial susceptibility testing was performed by means of Kirby-Baner.</p><p><b>RESULTS</b>Thirty-six H. pylori strains were identified. The resistant rate of H. pylori strains to clarithromycin, fruranzolidone and amoxicillin was 8.3%, 16.7% and 33.3%, respectively. H. pylori strains showed a high resistance to metronidazole (94.4%), while no strain was resistant to gentamicin and levofloxacin.</p><p><b>CONCLUSIONS</b>The H. pylori strains from the adolescents in Zhejiang showed a high resistance to metronidazole and amoxicillin but a low resistance to clarithromycin and fruranzolidone. All of H. pylori strains were susceptive to gentamicin and levofloxacin.</p>

Objective To explore the therapy measurement of iron deficiency anemia(IDA)associated helicobacter pylori(HP)infection among children.Methods Eight hundred and ninty nine cases entrusted children aged from 2 to 7 years old were measured hemoglobin(Hb),mean corpuscular volume(MCV)mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC)and serum ferri,serum fettin(SF),HP-IgG antibodies.Divided the HP-IgG positive cases into two groups for treatment,The treatment group adopted omeprazole,amoxicillin and metronidazole to cure them for two weeks,then oral ferrous sulfate sugar liquid.The contrast group purely take the ferrous sulfate sugar liquid.After eight weeks re-examined the Hb and SF.Results Totally 279 cases were diagnosed as Hp-positive,620 as HP-negative and 99 children diagnosed as IDA,among the 99 cases IDA,58 cases with HP infection(20.8%) and 41 cases with non-HP infection(6.7%).That means the number of IDA cases with HP infection was higher than those with non-HP infection(?2=39.46 P
