Background: Gastritis can reduces the hemoglobin level. Based on previous study, gastritis resulted from Helicobacter pylori infection often correlated to anemia as the capability of Helicobacter pylori to obtain iron from hemoglobin and transferrin. Objective: To analysis the differences of hemoglobin and transferrin level between Helicobacter pylori gastritis and non-Helicobacter pylori gastritis in children. Method: A cross sectional study was conducted on outpatient and inpatient in Haji Adam Malik General Hospital, Medan and network hospitals on March ? April 2020, subject ages from 2 to 18 years, diagnosed with Helicobacter pylori gastritis and non-Helicobacter pylori gastritis based on CLO test. Blood sample was taken from subjects to evaluate hemoglobin and transferrin level. Result: 54 subjects with gastrointestinal complaints were recruited. Subjects were divided into 2 groups based on CLO test, 32 subjects with Helicobacter pylori and 22 subjects without Helicobacter pylori. From blood sample analysis, mean hemoglobin and transferrin value from Helicobacter pylori group was 10.9 gr/dL and 253.5 mg/dL. Meanwhile, mean hemoglobin and transferrin value from non-Helicobacter pylori group was 10.8 gr/dL and 261.9 mg/dL. (p>0.05). Conclusion: No difference in hemoglobin and transferrin level between Helicobacter pylori gastritis and non-Helicobacter pylori gastritis in children.
