The metabolism of iron-poly (sorbitol-gluconic acid) complex (Ferastral) was studied in 6 blood donors with latent iron deficiency and 13 patients with manifest iron deficiency anaemia. Between 125 and 1 000 mg of iron were injected. In latent deficiency an average of 19% of the dose given was excreted during the first two weeks. The corresponding figure for patients with manifest iron deficiency was 11%. An average of 8% of the dose was retained at the site of injection after 40 days. In the two groups, respectively, 61% (range 47%-70%) and 58% (range 24%-86%) of the iron retained was incorporated into red cells after 40 days, which is judged to be quite satisfactory. Some local side effects were observed.

This paper is a progress report on our present understanding of iron nutrition in man, particularly in developing countries. We will be concerned with the quantitative aspects of iron balance and in particular with the availability of dietary iron, the recognition of iron deficiency and its prevalence, the effects of iron deficiency on the well being of the individual, and the feasibility of modifying the iron balance of man by dietary means.

In connection with a large multiphasic screening programme carried out in Finland the prevalence rate of anaemia and iron deficiency were studied. Hb was under 130 g/l in 7.9 per cent of the men aged 65 years or over and under 120 g/l in 3.8 per cent of the women in the same age range. Transferrin saturation was under 15 per cent in 6.4 per cent of the men and in 7.7 per cent of the women. Iron deficiency was especially common in the rural population. A dietary study showed that iron deficient persons consumed less meat products and more liquid milk products than the others. The dietary factors are significant in the etiology of iron deficiency.

For the most part iron deficiency, but also disturbances of distribution, transport and utilization of iron, are able to cause anemias. To understand the origin of such anemias, firstly iron metabolism, then the clinical symptomatology as well as the laboratory parameters necessary for diagnosis and finally the usual therapies are described.

Aim of the study was the evaluation of the diagnostic value of the parameters of iron metabolism in normal adults and also in patients suffering from uncomplicated iron deficiency, iron overload due to repeated blood transfusions, malignant lymphoma and Crohn's disease. In these patients, the determination of serum ferritin increased the diagnostic efficiency only in poly-transfused patients with iron overload.

Causes of anaemia in 101 adult Melanesian patients admitted to Port Moresby General Hospital over a 3-year period with haemoglobin levels of 4.0 gms per 100 ml or less were studied retrospectively. Cases of anaemia due to acute haemmorrage were excluded. Iron deficiency was found in 80, haemolysis in 39, megloblastosis in 26 and anaemia of chronic diseases in 5 patients. Anaemia was secondary to multiple causes in 56 and to a single cause in 45 patients. In the group with multiple causes, a combination of iron deficiency and haemolysis was found in 28, iron deficiency and megaloblastosis in 18, iron deficiency, haemolysis and megaloblastosis in 6 and haemolysis and megaloblastosis in 5 patients. In the group with a single cause, iron deficiency was found in 34, anaemia of chronic diseases in 5, haemolysis in 4 and megaloblastosis in 2 patients. Hookworm infestation and malaria appeared to be the major underlying causes of anaemia in the majority of these patients. Three of 45 patients who had received blood transfusions shortly after admission to the hospital died, while there was only one death in the nontransfused group. It is concluded that: i) severe anaemia in Papua New Guinea is commonly secondary to multiple causes; ii) administration of iron and folic acid as well as treatment for malaria and hookworm is a responsible approach when these patients can not be investigated; and iii) blood transfusion does not appear to be necessary in this group of patients despite a very low haemoglobin level.

The amount and effectiveness of erythropoiesis was measured using 59Fe in 10 patients with the anaemia of chronic disease and in 10 iron deficient patients with a comparable degree of anaemia. In both conditions the anaemia was the result of the failure of the marrow to compensate for a modest degree of peripheral haemolysis but ineffective erythropoiesis was significantly greater in iron deficiency than in chronic disease. The results suggest that although the peripheral blood picture is similar in both conditions the anaemia of chronic disease cannot be attributed simply to iron deficient erythropoiesis.

Nutritional anaemia, due chiefly to iron deficiency, is widely prevalent in many parts of the world. There is increasing evidence that even mild anaemia affects health and reduces productivity and that a high prevalence of anaemia has profound socioeconomic consequences. The pathogenesis of nutritional anaemia is now reasonably well understood. Measures avilable for combating it include: therapeutic supplementation for accessible population groups with a high prevalence of anaemia, such as pregnant women and schoolchildren; iron fortification of one or more widely consumed foodstuffs; management of those conditions, such as hookworm infestation, that increase requirements for haemopoietic nutrients; and education of the public, and of all categories of health personnel, regarding the importance of anaemia and the ways of controlling it. Experience has shown that there is no simple solution to the problem and in each area where iron deficiency anaemia is prevalent it will probably be necessary to develop and combine many or all of these measures. In each community it will be necessary to introduce these measures so that their effectiveness can first be studied in a pilot trial. When this has been successfully completed it should be followed by a field trial under realistic conditions, and only when this has proved successful should a regional or national programme be introduced. However, the problem is complex and it is only by sustained effort of all concerned that it will prove possible to develop adequate public health control of nutritional anaemia.

24 children in whom coeliac disease had been diagnosed between one and 10 years earlier were re-examined for intestinal loss of iron and activity of the disease. Mild iron deficiency by laboratory criteria and by response to iron medication was common. The children with biopsy evidence of flat mucosa or intraepithelial lymphocytosis had a greater iron loss in their stools than those patients with normal, or almost normal, histology. The data suggest that loss of iron was mainly due to intestinal blood loss rather than to shedding of mucosal cells. We conclude that treatment with iron is indicated in many children with coeliac disease as the increased losses of iron persist for long periods although absorption of iron seems to improve or be negligibly affected.

A prospective study was performed over 15 months to determine the cause of iron deficiency in adult males and postmenopausal females attending a general hospital. The laboratory computer identified all subjects with a haemoglobin less than 10.6 g/dl and a mean corpuscular volume less than 86 fl. Patients becoming anaemic after trauma or recent surgery were excluded. The iron status of each patient was assessed by serum iron studies, serum ferritin or sternal marrow aspiration. Reduced red cell indices and blood film morphology were not diagnostic of iron deficiency. Of 215 patients assessed, about half (103) were found to be iron replete. This group had a variety of disorders--malignancy, chronic inflammation, chronic renal and non-malignant haematological diseases. The other group of 104 patients satisfied criteria for iron deficiency, and 100 of these were investigated further. The cause of iron deficiency was found in all but three subjects. Inadequate dietary intake was a contributing factor in over half of the patients and 40 regularly took salicylates. Investigation defined a source of chronic gastrointestinal blood loss in most instances.
