The treatment of iron-deficiency anaemia in pregnancy with a new intramuscular iron preparation, iron-poly (sorbitol-gluconic acid) complex (Ferastral), has been assessed and compared with oral iron therapy. Sixty-one of the eighty-four patients studied, many of whom had mild to moderate degree of anaemia were treated with Ferastral. The results were satisfactory, the mean increase of haematocrit at the sixth post treatment week was 28.7% for the whole series. Complete correction of anaemia was achieved in most patients between the 4th and 6th week of treatment. The mean haematocrit of the group treated with oral iron was initially significantly higher than for the group treated with Ferastral. At the first follow-up, two weeks after beginning treatment, the mean values for both groups were similar; at four weeks, those receiving Ferastral had a significantly higher mean PCV than those on oral iron, and remained so through the period of observation. No side-effects were detected using 10 ml of Ferastral intramuscularly on alternate days. The mean hospitalization time of patients with severe to moderate anaemia was reduced when given parenteral therapy, and the frequency of blood transfusion in these patients was also decreased.

Thirteen pregnant women with iron-deficiency anaemia have been treated with Ferastral. In a further seven women, Ferastral was given 24 hours before delivery, when induction of labour was indicated, to investigation of iron concentration in maternal serum, cord blood and amniotic fluid simultaneously. The efficacy of Ferastral was demonstrated by a significant increase in haemoglobin and haematocrit. No serious reactions occurred and no evidence was found of disturbance of liver or renal function. It was shown that Ferastral does not pass the placental barrier and that no direct transport takes place through the uterine wall or amnion. No effects on the newborn were demonstrated.

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.

As a rule bacterial infection is followed by acute serum iron reduction; impaired inflow of iron from storage sites into the transport pool represents the main cause. As a consequence of this sort of iron redistribution iron becomes short for red cell production; this is one cause for the development of anemia. The biological significance of hyposideremia may be presumed from the bacteriostatic potential of iron free transferrin, preventing adequate iron acquisition by multiplying microorganisms. Preliminary animal experiments support this concept and suggest that it might also be applied to true iron deficiency.

Since 1949, the World Health Organization, recognizing the public health importance of nutritional anemia, has sponsored efforts directed towards its understanding and control. During this period, often as a result of the work of the Organization, advances have been made in many areas. Basic understanding of iron, folate and vitamin B12 nutrition, and the various factors which may influence the availability and requirements of these factors, has greatly increased. Surveys in a number of countries have highlighted the widespread prevalence of nutritional anemia, particularly in developing countries. The major factor responsible is a deficiency of iron, whith folate deficiency also playing a role in some population groups, especially in preganant women. There is increasing evidence that anemia adversely affects the health of individuals and may have profound socioeconomic consequences. Control of nutritional anemia is possible by providing the deficient nutrient(s) either as therapeutic supplements or by fortification of commonly used foodstuffs. Some control programs are reviewed and suggestions for further action outlined. The Organization still has an important role to play in this field, encouraging the development of control programs and providing advice and technical assistance ot member countries.

Two brothers, aged 3 and 6 years, respectively, had their pulmonary conditions diagnosed as idiopathic pulmonary hemosiderosis (IPH). Both boys had severe iron-deficiency anemia, chronic cough, hemoptysis, and exertional dyspnea, and one had recurrent epistaxis. The results of light microscopic lung histopathologic studies in both patients showed numerous hemosiderinladen macrophages and chronic interstitial pneumonitis. No specific patterns of immunofluorescence of the alveolar capillary basement membranes were found. The results of electron microscopic examinations showed intact alveolar and capillary basement membranes and no evidence of electron-dense deposits. The lack of clinical or biochemical evidence for renal disease as well as the absence of serum antinuclear and antibasement membrane antibodies excluded associated autoimmune disorders. Evaluation for milk-protein allergy was negative and neither child demonstrated a clinical response to a milk-free diet. Sequential pulmonary function studies performed over four years showed episodes of acute obstructive airway disease that correlated with pulmonary hemorrhage and mild persistent restrictive lung disease. The results of this family study suggested that some cases of IPH may have a genetic basis.

In 90 patients with prosthetic heart valves, the presence of iron and folate deficiencies was assessed in a double-blind study. Anemia was found in 18 cases. Average serum iron levels were below the normal range and could be incremented significantly through the administration of 193 mg Fe++ daily during a 4-week period. No evidence of folate deficiency was found.

Thalassemia major is a severe and transfusion-dependent anemia that occurs in persons homozygous for a mutation that affects the capacity for synthesis of the beta-globin subunit of hemoglobin. Characterization of the molecular defects that cause beta-thalassemia is providing insight into the mechanism of globin gene regulation. Newer approaches to the management of thalassemia major include more effective chelation by use of subcutaneous desferrioxamine and attempts to obtain young erythrocytes with a longer potential for survival in recipient patients. Development of more effective chelators that may be given orally is an ongoing effort. Noninvasive evaluation of cardiac structure and function in patients with thalassemia major suggests that myocardial iron deposits begin at an early age, causing functional impairment long before the onset of clinical symptoms. Prevention or reversal of these cardiac abnormalities remains the goal of chelation therapy.

The role of the metals, iron and copper, and the vitamins E, folic acid, and B12 in the genesis of nutritional anemias in infancy have been reviewed. All are preventable. The precise requirements for each of these trace elements and vitamins in the small premature infant remain to be defined. The nonhematologic consequences of these nutritional deficiencies require further study. Anemia may prove to be the least important manifestation of the deficiency states.

Ferritin is an iron storage protein of high-molecular weight which is primarily present in the liver, spleen, and bone marrow. A very sensitive immunoradiometric assay has been developed which permits determination of serum concentrations in normal persons and in patients with a variety of different disorders. In normal subjects, the serum ferritin concentration correlates very well with total body iron stores as measured by phlebotomy. The serum ferritin concentration is reduced in patients with iron-deficient anemia and is significantly higher in patients who are anemic for other reasons. Subject areas discussed in this review include the details of the immunoradiometric procedure, the sensitivity and accuracy of the assay, factors influencing the assay, values characteristic of a variety of clinical disorders, and the utility of the assay in clinical medicine and public health.
