Treatment of anemia with microencapsulated ferrous fumarate plus ascorbic acid supplied as sprinkles to complementary (weaning) foods.

BACKGROUND: Standard therapy for anemia in infants is ferrous sulfate drops administered 3 times/d. Adherence to treatment, however, is often poor. One likely reason for poor adherence is the unpleasant side effects associated with drops. OBJECTIVE: The objective was to evaluate the use of a new form of iron and a delivery system to treat anemia in infants that is likely to produce better adherence to treatment. DESIGN: Using a prospective, randomized, controlled design, we studied 557 anemic children aged 6-18 mo (hemoglobin: 70-99 g/L) in rural Ghana. One group received a daily sachet of microencapsulated ferrous fumarate (80 mg elemental Fe) in powder form plus ascorbic acid to be sprinkled onto any complementary food eaten (sprinkles group); a control group received ferrous sulfate drops 3 times/d for 2 mo (total dose: 40 mg elemental Fe). Hemoglobin and serum ferritin concentrations were measured at baseline and at the end of treatment. RESULTS: Successful treatment of anemia (hemoglobin > 100 g/L) occurred in 58% of the sprinkles group and in 56% of the drops group, with minimal side effects in both groups. Geometric mean ferritin concentrations increased significantly in each group from baseline to the end of treatment (P < 0.001). CONCLUSION: Use of ferrous sulfate drops or a single daily dose of microencapsulated ferrous fumarate sprinkles plus ascorbic acid resulted in a similar rate of successful treatment of anemia without side effects. To our knowledge, this is the first demonstration of the use of microencapsulated iron sprinkles to treat anemia. Improved ease of use may favor the use of sprinkles to deliver iron.

Randomized, controlled trial of single versus 3-times-daily ferrous sulfate drops for treatment of anemia.

OBJECTIVE: Adherence to treatment of iron-deficiency anemia often is poor in both developed and developing countries. The current standard therapy is ferrous sulfate drops (or syrup) administered 3 times daily. It is possible that adherence would improve with a single-dose daily treatment regimen. We compared the use of single versus 3-times-daily ferrous sulfate drops, at the same total iron dose, on treatment of anemia in infants. METHODS: To obtain a large enough cohort of anemic subjects, we performed the study in rural Ghana. Using a prospective, randomized, controlled design, we studied 557 anemic children (age range: 6-24 months; hemoglobin values: 70-99 g/L). One group (n = 280) received ferrous sulfate drops once daily (40 mg elemental iron), and the control group (n = 277) received ferrous sulfate drops 3 times per day (total dose, 40 mg elemental iron). Treatment lasted for 2 months. Hemoglobin and serum ferritin values were measured at baseline and at the end of the study. RESULTS: Successful treatment of anemia (hemoglobin >100 g/L) occurred in 61% of the single-dose and in 56% of the 3-times-daily group. Geometric mean ferritin levels increased significantly in each group from baseline to the final visit. Side effects were minimal and similar between the 2 groups. CONCLUSION: A single versus a 3-times-daily dose of ferrous sulfate drops over 2 months resulted in a similar rate of successful treatment of anemia, without side effects. To our knowledge, this is the first demonstration of the use of a single-dose daily regimen to treat anemia. Although not examined in the current study, use of a single-dose daily regimen may improve adherence to treatment of anemia in infants.

Criteria for clinical audit of the quality of hospital-based obstetric care in developing countries.

Improving the quality of obstetric care is an urgent priority in developing countries, where maternal mortality remains high. The feasibility of criterion-based clinical audit of the assessment and management of five major obstetric complications is being studied in Ghana and Jamaica. In order to establish case definitions and clinical audit criteria, a systematic review of the literature was followed by three expert panel meetings. A modified nominal group technique was used to develop consensus among experts on a final set of case definitions and criteria. Five main obstetric complications were selected and definitions were agreed. The literature review led to the identification of 67 criteria, and the panel meetings resulted in the modification and approval of 37 of these for the next stage of audit. Criterion-based audit, which has been devised and tested primarily in industrialized countries, can be adapted and applied where resources are poorer. The selection of audit criteria for such settings requires local expert opinion to be considered in addition to research evidence, so as to ensure that the criteria are realistic in relation to conditions in the field. Practical methods for achieving this are described in the present paper.
