Iron Deficiency Anemia Refractory to Conventional Therapy but Responsive to Feralgine® in a Young Woman with Celiac Disease

Iron, which is an important micronutrient in the human body may be deficient in people with celiac disease (CD). Iron deficiency anemia (IDA) may be the presenting feature of celiac disease, also in the absence of diarrhea or weight loss. The treatment of IDA in patient with CD is primarily a gluten-free-diet (GFD), but it is also very important oral iron supplementation until the iron stores have been restored. However, a frequent problem in CD is the poor tolerability and poor efficacy of oral iron preparations. A new product, consisting of the combination of Ferrous Bysglicinate Chelate and Sodium Alginate (Feralgine™), has been demonstrated to be more bioavailable and well tolerated in CD. We present a case report that showed a clear efficacy of this product in a form of IDA refractory to conventional therapy in a woman with CD and we demonstrated a clear increase of serum iron after administration of this new type of ferrous.

A double-blind, randomized, and active-controlled phase III study of Herbiron drink in the treatment of iron-deficiency anemia in premenopausal females in Taiwan

Background

About 468 million non-pregnant women are estimated to suffer from iron-deficiency anemia (IDA) worldwide. The highest prevalence of IDA occurs in the Taiwanese population.

Objective

To evaluate the effectiveness of Herbiron to increase iron absorption in women with IDA.

Design

Phase III double-blind, randomized, active-controlled, and parallel comparative study enrolled 124 patients with IDA and consisted of a 2-week run-in period, randomization, 12 weeks of supplementation, and 4 weeks of follow-up. The treatment group received Herbiron drink 50 mL p.o., b.i.d., before meals (daily iron intake: 21 mg/day) plus placebo tablets. The control group received a ferrous sulfate tablet, t.i.d., plus placebo 50-mL drink before meals (daily iron intake: 195 mg/day).

Results

Both treatments significantly improved hemoglobin and all secondary efficacy endpoints. Most IDA patients treated with Herbiron or ferrous sulfate finished the study in the normal range. Ferrous sulfate treatment induced a rapid rate of hemoglobin synthesis, which plateaued by week 8, whereas Herbiron treatment increased the rate of hemoglobin synthesis more slowly, likely due to its nine-fold lower iron content. Gastrointestinal adverse events (diarrhea, abdominal pain, dyspepsia, and nausea) but not infectious adverse events were significantly more common in the ferrous sulfate group (n=11, 18.3%) than those in the Herbiron group (n=1, 1.6%) (p=0.004).

Conclusion

Twelve weeks of Herbiron treatment delivering 21mg of iron or ferrous sulfate treatment delivering 195 mg of iron induced normal hemoglobin levels in 62 or 91% of non-pregnant women with IDA in Taiwan, respectively, suggesting dose-dependent and bioavailability effects.
