Nappi C, Tommaselli GA, Morra I, Massaro M, Formisano C, Di Carlo C: Efficacy and tolerability of oral bovine lactoferrin compared to ferrous sulfate in pregnant women with iron deficiency anemia: a prospective controlled randomized study. Acta Obstet Gynecol Scand. 2009;88(9):1031-5.
OBJECTIVE: To compare the effects of bovine lactoferrin with ferrous sulfate on iron nutritional status and to evaluate their tolerability in 100 pregnant women with iron deficiency anemia. DESIGN: Prospective, randomized, controlled, double blind trial. SETTING: Obstetrics clinic of a University Department of Obstetrics and Gynecology. POPULATION: One-hundred pregnant, healthy women to be treated either with one capsule of 100 mg bovine lactoferrin twice a day (Group A; n=49) and 520 mg ferrous sulfate once a day (Group B; n=48). METHODS: After 30 days, we evaluated hemoglobin (Hb), serum ferritin, serum iron and total iron- binding capacity (TIBC) values. All women were asked to keep a diary of five potential gastrointestinal side effects (abdominal pain, nausea, vomiting, diarrhea and constipation). For each symptom, patients had to rate its severity according to a scale ranging from 0 (absent) to 3 (severe). MAIN OUTCOME MEASURES: Hb level before and after treatment. Secondary outcomes were serum ferritin, serum iron and TIBC levels and the difference in symptom scores between groups. RESULTS: In Groups A and B, Hb, serum ferritin and iron were significantly increased while TIBC was significantly reduced in comparison with basal values. No significant differences were observed between Groups A and B. The median scores of abdominal pain and constipation were significantly higher in patients treated with ferrous sulfate in comparison with those treated with bovine lactoferrin. CONCLUSIONS: The results show that bovine lactoferrin has the same efficacy as ferrous sulfate in restoring iron deposits with significantly fewer gastrointestinal side effects. |
