The incidence of anemia in 259 patients with a diaphragmatic hernia large enough to be seen on a routine chest roentgenogram was compared with that in 259 age- and sex-matched controls. Eighteen patients with diaphragmatic hernia were anemic, compared to one control subject (P less than 0.001). In thirteen patients with diaphragmatic hernia and in one control the anemia was proven to be caused by iron deficiency. The findings provide additional evidence that a large diaphragmatic hernia can cause anemia secondary to chronic gastrointestinal blood loss, which is usually not the result of reflux esophagitis.

Diagnosis is often overlooked because symptoms develop slowly and insidiously and many patients don't complain about them. Then too, the giddiness, apathy, confusion, clumsiness, and similar problems may be considered simply signs of "old age." Iron deficiency anemia is the most common type in old people. It's usually due to gastrointestinal bleeding, but there may be a second, less obvious cause. The classic picture of low serum iron, high total iron-binding capacity, and low iron-binding saturation is sometimes distorted. Usually, many studies are needed to confirm the suspicion of a vitamin B12 or folic acid deficiency. A raised mean corpuscular volume in itself signals the need for further investigation. In patients with macrocytosis, the bone marrow must be examined. Tests for intestinal malabsorption must be considered too. Repeated blood tests are essential in patients being treated for any type of anemia. Iron deficiency may hide evidence of folate or B12 deficiency. And iron therapy may lessen bleeding from colonic cancer, delaying diagnosis until it's too late to operate.

Porotic hyperostosis was observed in 34 percent of 539 crania excavated from sites in Arizona and New Mexico. Common causes of this cranial pathology in the Old World (thalassemia, sickel cell anemia, and malargia) do not explain its occurrence in the American Southwest, as malaria and hemoglobinopathies are not known to have existed in the New World prior to European contact. Iron deficiency anemia which may also be assoicated with porotic hyperostosis occurs on a mass level only with hookworm infestation or nutritionally-related iron deficiency. Since hookworm infestation is rare in the American southwest and has not been reported in prehistoric southwestern American Indians, the hypothesis of nutritional anemia was examined. In canyon bottom sites where the diet was heavily dependent on maize, which is low in iron and also contains an inhibitor of iron absorption, significantly more crania had porotic hyperostosis than in sage plain sites, where the diet included ample animal protein rich in easily absorbable iron (p less than .001). Furthermore, canyon bottom children, who were more susceptible to iron deficiency anemia, had a higher incidence of porotic hyperostosis lesions than adults (p less than .0001).

Out of 6000 regular blood donors at a regional blood donation service 135 women (5.44%) and 24 men (0.68%) were found to have low hemoglobin levels (borderline for females 12.4 g%, for males 13.2g%). In only half of these donors could the anemia be ascribed to iron deficiency or overt disease. In the other half no explanation was found for the low hemoglobin levels and iron therapy did not improve the situation. It is concluded that a small part of the healthy population persistently shows subnormal hemoglobin levels without presenting other pathology.

We describe a 25-year-old black woman who presented with a long history of anemia requiring transfusions during childhood and adolescence. Molecular analysis revealed her to be a compound heterozygote for the sickle mutation and the approximately 22.7 kb deletion associated with hemoglobin Kenya. This patient's clinical course was more severe than previously reported for the Hb S/Hb Kenya genotype, a probable consequence of concomitant iron deficiency.

Despite major advances in our knowledge of iron nutrition in infancy, iron deficiency remains a significant problem in the UK. The precise size of the problem is unknown, but there appears to be a higher risk amongst certain ethnic groups. Nutritional iron deficiency appears after the age of 6 months and is undoubtedly linked to inappropriate feeding practice. High bioavailability of iron in weaning foods is of paramount importance in preventing iron deficiency, whether using family foods or commercially available products, and further information about different foods and diets is needed. The long-term detrimental effect on mental development makes prevention of iron deficiency a high priority public health objective for the 1990s.

To investigate the etiology of the age-related decrease in hemoglobin (Hb) concentration, we measured serum erythropoietin (EPO), serum iron, total iron binding capacity, and serum ferritin levels in 247 elderly subjects aged 60-99 years. EPO levels were determined by radioimmunoassay. An age-related increase in the serum EPO concentration (r = 0.220; P < 0.01) and a significant inverse relationship between EPO and Hb concentrations were found in normal elderly subjects without anemia (r = -0.302; P < 0.001), but not in 111 younger controls. Serum EPO levels were slightly higher in elderly subjects with pre-anemic iron deficiency than in the normal elderly subjects (P < 0.05). These results suggest that the EPO secretion is accelerated in the elderly even though the Hb remains above 12.0 g/dl, probably as a compensatory mechanism for peripheral tissue hypoxia. An inverse relationship between the EPO and Hb concentrations was found in the elderly subjects with iron deficiency anemia, but not in those with unexplained senile anemia. The changes of EPO levels were also assessed in 20 elderly subjects who had developed anemia when reviewed after 12 months. Serum EPO levels increased in relation to the decrease in Hb concentration in those with iron deficiency anemia, but not in those with unexplained senile anemia. Reduced EPO secretion thus seems to play a role in the progression of unexplained senile anemia, and recombinant human EPO may possibly be effective for treating this type of anemia by mobilizing excess iron.

Iron status of pregnant women at different stages of pregnancy was evaluated by comparing values for hemoglobin (Hb), red cell indices, serum iron (SI), transferrin saturation (TS) and serum ferritin (SF) values with those of a group of non-pregnant women of comparable age and socio-economic status. Mean SF values on the second and third trimesters (9.3 +/- 2.60 ng/ml and 7.1 +/- 2.19 ng/ml) were significantly lower compared to that in the first trimester (22.6 +/- 2.20 ng/ml). These levels were also lower than that found in the non-pregnant controls. The trend was the same for TS. Hemoglobin levels of the pregnant subjects were significantly lower than those of the non-pregnant women. Prevalence of iron deficiency based on SF < 12.0 ng/ml and TS < 16.0% was highest at term and lowest during the first trimester indicating a decrease in iron stores as pregnancy progressed. Sensitivity for each of the iron parameters was computed, and it was found that for the diagnosis of iron deficiency in pregnant women, SF has a greater sensitivity than TS, SI, MCV and MCH.

Blood biochemical indices of iron status were measured in venous blood from 20 runners and 6 control subjects. All subjects were male, ages 20 to 40 years, and stable with regard to body weight and degree of physical activity. Dietary analysis was undertaken using a 7-day weighed food intake. There was no evidence of iron deficiency: hemoglobin concentrations and serum ferritin levels were within the normal population range for all individuals. However, serum ferritin was negatively correlated with the amount of training. Daily iron intake appeared to be adequate; iron intake was correlated with protein intake but not related to training or energy intake. Serum ferritin, an indicator of iron status, was significantly correlated with vitamin C intake but not iron intake. Serum transferrin concentration was higher in the group of athletes undertaking a high weekly training load compared with the control subjects, suggesting an alteration in iron metabolism although there was no evidence of increased erythropoiesis. The biological significance of this is unclear.

Routinely measuring iron status is necessary because about 6% of Americans have negative iron balance, about 10% have a gene for positive balance, and about 1% have iron overload. Deviations from normal iron status are as follows. (a) Stage I and II negative iron balance, ie, iron depletion: In these stages iron stores are low and there is no dysfunction. In stage I negative iron balance, reduced iron absorption produces moderately depleted iron stores. Stage II negative iron balance is characterized by severely depleted iron stores. More than half of all cases of negative iron balance fall into these two stages. When persons in these stages are treated with iron, they never develop dysfunction or disease. (b) Stage III and IV negative iron balance, ie, iron deficiency: Iron deficiency is characterized by inadequate body iron for normal function, producing dysfunction and disease. In stage III negative iron balance, dysfunction is not accompanied by anemia; anemia develops in stage IV negative iron balance. (c) Stage I and II positive iron balance: Stage I positive balance usually lasts for several years with no dysfunction. Supplements of iron and/or vitamin C promote progression to dysfunction or disease. Iron removal prevents progression to disease. Iron overload disease develops in stage II positive iron balance after years of iron overload has caused progressive damage to tissues and organs. Again, iron removal stops disease progression. There are a variety of indicators of iron status. Serum ferritin is in equilibrium with body iron stores.(ABSTRACT TRUNCATED AT 250 WORDS)
