pyrophosphate and ferrous-gluconate

This study aimed at evaluating the effects obtained by administering 30 mg of micronised dispersible ferric pyrophosphate plus 300 mg of alpha-lactalbumin (MDFP-AL) compared to 80 mg of ferrous gluconate (FG) in pregnant women affected by iron-deficiency anemia (IDA).. We considered eligible all second-trimester singleton pregnancies in women affected by IDA. We excluded any other disease, twin pregnancies, any other pharmacologic/nutraceutical treatments (besides folic acid) before/during pregnancy. We randomized patients in two groups: one underwent treatment with 1 tablet of MDFP-AL/day, the other one with 1 tablet of FG/day, for 30 days. We evaluated hemoglobin (Hb), ferritin, red blood cells (RBCs), serum iron, hematocrit (Hct), and side effects at baseline (T0), after 15 days (T1) and 30 days (T2).. 50 women met the inclusion/exclusion criteria. We did not observe significant differences between the two groups for mean age, gestational age at the enrollment and parity. In MDFP-AL group, after 15 days (T1) Hb, ferritin, serum iron and Hct and were significantly improved respect to baseline (T0); after 30 days (T2), all the parameters, including RBCs, were significantly improved respect to baseline (T0). Similarly, in FG group the investigated parameters were improved both after 15 (T1) and 30 days (T2) respect to baseline (T0), although less in percentage terms respect to MDFP-AL group. The side effects rate was 24% in FG group, whereas MDFP-AL group did not show any significant side effect.. Overall, MDFP-AL is more effective and safe than FG for the treatment of IDA in pregnant women.

Although potassium sorbate (PS), ascorbic acid and ferric or ferrous salts (Fe-salts) are used widely in combination as food additives, the strong reactivity of PS and oxidative potency of ascorbic acid in the presence of Fe-salts might form toxic compounds in food during its deposit and distribution. In the present paper, the reaction mixture of PS, ascorbic acid and Fe-salts was evaluated for mutagenicity and DNA-damaging activity by means of the Ames test and rec-assay. Effective lethality was observed in the rec-assay. No mutagenicity was induced in either Salmonella typhimurium strains TA98 (with or without S-9 mix) or TA100 (with S-9 mix). In contrast, a dose-dependent mutagenic effect was obtained when applied to strain TA100 without S-9 mix. The mutagenic activity became stronger increasing with the reaction period. Furthermore, the reaction products obtained in a nitrogen atmosphere did not show any mutagenic and DNA-damaging activity. PS, ascorbic acid and Fe-salts were inactive when they were used separately. Omission of one component from the mixture of PS, ascorbic acid and Fe-salt turned the reaction system inactive. These results demonstrate that ascorbic acid and Fe-salt oxidized PS and the oxidative products caused mutagenicity and DNA-damaging activity.
