Helicobacter pylori and anemia with pregnancy.

SUBJECTS AND METHODS: Study was conducted in Ain Shams University hospitals on 100 pregnant women with iron-deficiency anemia (IDA), including 50 cases infected with Helicobacter pylori (H. pylori) and 50 cases negative for H. pylori infection. Cases with symptomatic gastritis or hyperemesis gravidarum were not included in the study, obstetric history, sociodemographic and dietary variables were also assessed. Hemoglobin level, serum iron, serum ferritin, total iron binding capacity (TIBC), H. pylori serum antibody, stool analysis to exclude parasitic infection causing IDA, occult blood in stool and ultrasound for the fetus to ensure its cardiac pulsations and to exclude any associated abnormality were all done for all patients. Iron therapy in a fixed dose was given to all patients for 1 month. Response was estimated and statistical comparison was done between both groups. Eradication of H. pylori was done in positive cases by triple therapy in the second trimester and iron therapy was given after treatment in the same dose for another month. Their response to treatment after eradication was compared to their response to iron therapy prior to H. pylori eradication. RESULTS: Hb levels, serum iron, serum ferritin were lower and TIBC was higher in H. pylori-infected cases than negative ones. The average rise of Hb in cases negative to H. pylori was higher than those positive to H. pylori. After comparing response of cases infected with H. pylori to iron therapy before and after eradication of H. pylori, it was found that rise of Hb was higher after treatment than before eradication of H. pylori. CONCLUSION: Response to iron therapy in cases of iron deficiency anemia in patients without H. pylori infection was better than those infected with H. pylori. H. pylori eradication in the infected cases increased their response to iron therapy.

Role of Helicobacter pylori in the pathogenesis of hyperemesis gravidarum.

PURPOSE: To evaluate the role of Helicobacter pylori (H. pylori) in the pathogenesis of hyperemesis gravidarum (HG) and the value of adding a non teratogenic regimen for its treatment in intractable cases. METHODS: Eighty hyperemesis gravidarum cases were recruited from Ain Shams University out patient clinics. A complete history was taken including history of medical disorders and chronic medications intake as non steroidal anti-inflammatory drugs. After general and local examination, ultrasound was done for all cases to exclude obstetric causes of hyperemesis. Eighty normal pregnant women acted as control. Serum test for H. pylori IgG antibody titre was done for all patients and controls. RESULTS: Seventy-one cases among the 80 HG cases and twenty-four out of the 80 controls were H. pylori positive. Eight HG cases developed severe intractable vomiting. Three of them developed attacks of hematemesis. Gastroscopy done for the eight cases revealed antral gastritis and duodenitis. Gastric and duodenal erosions were found in two cases. The eight patients received a non teratogenic regimen for treatment. Attacks of vomiting decreased and pregnancy continued till delivery of healthy newborns. CONCLUSION: Screening for H. pylori should be added to the investigations of hyperemesis gravidarum cases. Non teratogenic treatment can be considered in intractable cases.
