A clinical investigation of an iron-poly (sorbitol-gluconic acid) complex, Ferastral, for the treatment of iron deficiency anaemia has been performed. The study was designed to determine the dose schedule, efficacy and tolerance of the drug. Two dose intervals were used, 500 mg of iron once a week or every third day. The study comprised 26 adult patients. After single doses of 500 mg of Ferastral given every third day levels of iron and unsaturated iron binding capacity (UIBC) in serum were estimated. Maximum values of iron in serum after the first injection were reached after 24 hours in two patients. After the second injection there was a further increase in the iron concentration with maximum values after 24 to 48 hours. A decrease in UIBC was seen in all patients. Urinary excretion of iron was about 15%. Most of the excretion took place during the first 72 hours following the injection. The haemoglobin increase was more rapid in the group receiving 500 mg of iron every third day. The difference was statistically significant two to four weeks after commencing treatment. After five weeks the difference in haemoglobin increase was no longer statistically significant. After eight weeks the mean haemoglobin had reached 13.1 g/100 ml in the group treated once a week and 13.4 g/100 ml in the group treated every third day. The preparation was well tolerated by all patients treated. No local or general side effects were observed.

Ferastral, a new iron-poly (sorbitol-gluconic acid) complex for parenteral use has been given to 22 patients with iron deficiency anaemia. The patients were divided in two groups. Group I received a suboptimal dose of Ferastral iron corresponding to 90% of the iron calculated to normalize the haemoglobin value. Increases in total haemoglobin and also blood losses were measured. The availability of the injected iron for haemoglobin synthesis ranged from 63% to 111%. Group II received an amount of Ferastral-iron calculated to be necessary for normalization of the haemoglobin plus an additional 500 mg of Ferastral-iron. In this group the haemoglobin increase was rapid. In 7 weeks 10 out of 14 patients had reached a normal haemoglobin level.

An investigation has been carried out to study the efficacy of iron-poly (sorbitol-gluconic acid) complex (Ferastral) in the treatment of iron deficiency anaemia. Ferastral was given by the intramuscular route every second or third day in a dose of 500 mg, divided in two injections. These were compared with the results of a group treated with iron-dextran given by Total Dose Infusion (TDI). A total of 38 patients were treated with either Ferastral or iron-dextran by TDI, respectively, given according to random allocation. The total dose of iron given in both groups was 1 500 mg of elemental iron. The parameters investigated were haematocrit and haemoglobin. Side-effects were also recorded. The results in the group treated with Ferastral where the mean initial haemoglobin value was 9.5 g/100 ml showed a mean haemoglobin increase to 13.2 g/100 ml after eight weeks. Initial haemoglobin values and haemoglobin increase for iron-dextran by TDI were quite similar. Three patients in the Ferastral group had transient discolouration at the site of injection and one patient in the iron-dextran TDI-group had a serious allergic reaction.

A new intramuscular iron preparation (Ferastral) permitting high doses of iron (500 mg) to be given in two simultaneous of 250 mg, was tested in 20 courses given to 11 patients with iron deficiency anaemia. The total iron doses given ranged from 1 000-2 500 mg. The amount injected was calculated from the degree of haemoglobin deficiency. Additional 500-1 000 mg iron were given to fill the depots. Haemoglobin regeneration was satisfactory. Bone marrow aspiration to assess storage iron 2-14 weeks after treatment was carried out in most patients and showed restoration of stainable iron in bone marrow in those cases given Ferastral in doses of 500-1 000 mg greater than calculated to normalize haemoglobin concentrations. In two patients with persistent continued blood loss the bone marrow remained negative for stainable iron. Side-effects were negligible.

An investigation has been performed with a new parenteral iron preparation, iron-poly-(sorbitol-gluconic acid) complex (Ferastral) in the treatment with iron deficiency anaemia associated with inflammatory diseases, mainly rheumatoid arthritis. Fifteen moderately anaemic patients entered into the trial. These patients constituted a special group in whom the MCHCs were subnormal. Observations were made concerning the occurrence of side-effects. Particular attention was paid to those-side-effects which are known to be associated with the use of parenteral iron preparations in the treatment of rheumatoid subjects. Ferastral was administered by intramuscular by intramuscular injection. The single doses given on any one occasion varied from a minimum of 100 mg to a maximum of 500 mg, divided into two separate injections. The results of therapy, measured at eight weeks, showed significant increases in haemoglobin concentrations. Increases in erythrocyte count, MCHC and serum-iron concentration were also found. There were no signs of acute toxic effects with Ferastral and in no patient was there exacerbation of arthritis as has been previously reported with iron-dextran.

In a coastal population in whom anaemia was common, two randomised controlled trials were undertaken to investigate the effectiveness of treating iron deficiency anaemia at a dispensary and at primary schools. For anaemic adult villagers treated at a dispensary, one dose of tetrachlorethylene for hookworm infection and a once per week visit to collect medicines were found to be satisfactory. A small but significant increase in haemoglobin level was produced by four weeks oral iron therapy, but this was only maintained after seven months by the group that had initially also received tetrachlorethylene. In children (5-14 years) no significant rise in haemoglobin level was obtained by using oral iron and/or TCE, either at the dispensary or at the primary schools. This suggests that malaria was a more potent cause of anaemia in these children.

Iron deficiency anaemia was induced in rabbits by repeated bleeding. The leucocyte alkaline phosphatase (LAP) of 26 +/- 28 units was significantly reduced compared with control values of 233 +/- 35 units (P less than 0.001). Leucocyte NBT reduction was also diminished, both in Hanks solution (P less than 0.01) and in autologous serum (P less than 0.001). After administration of iron, these values returned to normal. The results suggest that reduced LAP may reflect a deficiency of iron dependent constituents which are necessary for the integrity of normal granulocyte metabolism.

Fe(III)-EDTA as iron fortification presents several advantages over the other iron salts previously used including ferrous sulfate. This iron compound exchange completely with vegetable food iron in the lumen of the gut but with the characteristics that the absorption from both, extrinsic and intrinsic food iron, is higher than that expected from other iron salfs. The comparison between the iron absorption from Fe(III)-EDTA and ferrous sulfate as iron fortification indicates that the absorption form EDTA is about twice as high than that observed from ferrous sulfate. The data indicates that only 10 to 15 mg of iron as Fe(III)-EDTA as iron fortification would be necessary to prevent iron deficiency anemia in population relying their subsistence of vegetable food only and free of parastic infection producing blood loss.

Iron deficiency anaemia secondary to menorrhagia was observed in a woman of Greek Cypriot origin. Moderate thrombocytopenia was also present. Treatment with parenteral and oral iron produced a transient thrombocytosis, the platelet count then returning to normal. Subsequent analysis revealed that she also carried the alpha1-thalassaemia trait. Previous reports of thrombocytopenia responsive to iron treatment are reviewed.

Lactoferrin (LF), the iron-binding protein of external secretions and neutrophilic polymorphonuclear leukocytes (PMN), was studied in 27 patients during granulocytosis caused by acute inflammation and in disorders without granulocytosis (iron deficiency anemia, iron overload and liver diseases). During granulocytosis the LF concentration of PMN was significantly lower than in controls (p less than 0.001). This difference proved to be related to the number of PMN. A relation between the LF concentration of PMN and iron metabolism could be demonstrated: loss of iron by blood donation is accompanied by a significant decrease in the LF concentration in PMN, whereas iron therapy in patients with iron deficiency anemia is accompanied by a significant increase in the LF concentration in PMN.
