Iron status, iron absorption, and intestinal blood loss were studied in 199 children undergoing diagnostic evaluation for suspected malabsorption. Evaluation of iron status included hematological indices, serum ferritin, and transferrin saturation. Iron absorption was assessed by the increment of serum iron after an oral iron load. Iron deficiency was common among patients affected by malabsorptive states, such as celiac disease (84%), cow's milk intolerance (76%), Crohn's disease (72%), and giardiasis (64%), whereas it was less common among patients with postinfectious enteritis (41%) and chronic nonspecific diarrhea (11%). Intestinal blood loss was seen only in patients with Crohn's disease and cow's milk intolerance, irrespective of iron nutritional status. On the other hand, iron malabsorption was very common, affecting 85-95% of the iron-deficient patients in all diagnostic groups, except in chronic nonspecific diarrhea. Iron malabsorption was less common among patients with adequate iron nutritional status than in those with iron deficiency. Iron malabsorption appears to play a major role in the pathogenesis of iron deficiency in patients with malabsorption. The iron absorption test shows greater sensitivity as a screening test for upper intestinal malabsorption than the D-xylose absorption test.

To assess the prevalence and species of intestinal parasitoses and to evaluate the effects of parasitic infections on the nutritional health of northeastern Thai children a survey was carried out among 343 urban and rural 3-8-year-olds in Sakon Nakhon province. Approximately 57% suffered from single or multiple helminthiasis (ancylostomiasis (AD), ascariasis (AL), opisthorchiasis (OV) and/or strongyloidiasis (SS)) and/or giardiasis (GL). In rural areas the prevalence of AD and SS was higher than in urban areas (p less than 0.01 and p less than 0.05 respectively). OV was found more frequently among 6-8-year olds (18%) than among 3-5-year olds (5%); among 3-5-year olds the prevalence of GL was higher than among 6-8-year olds (17 vs 8%). Multiple infections were observed in 13% of the children. Infected children showed lower daily intakes of protein, iron and riboflavin as well as lower menas for haemoglobin, haematocrit, serum ferritin, and Z-score height for age than non-infected children. The prevalence of stunted children was lower among non-infected children (32%) than among infected children (53%), and children with AL (49%), SS (55%), and GL (45%). Anaemia was found more frequently among the infected children (59%) and GL-children (61%) than among non-infected children (42%). Inadequate daily intake of energy and nutrients of most of the children, in combination with parasitic infections, still common in rural northeast Thailand, was shown to result in a serious public health problem.

We conducted a cross sectional study to examine the association of intestinal parasitic infections and protein energy malnutrition (PEM) with iron-status indicators and anaemia among Orang Asli children in Selangor, Malaysia. A total of 281 children aged 2 - 15 years were studied. The data were collected using structured questionnaires, anthropometric measurements and laboratory analysis for blood and faecal samples. All children were infected either by A. lumbricoides, T. trichiura or hookworm and almost 19%, 26% and 3% of the children had severe infection of ascariasis, trichuriasis and hookworm infection respectively. The prevalence of giardiasis among them was 24.9%. Overall, 41.5% of the children were anaemic (haemoglobin < 11.0 g/dL). Of these 61.0% of the children had iron deficiency and 36.5% had iron deficiency anaemia (IDA), which accounted for 88.0% of anaemia in this population. Severe trichuriasis had the most significant correlation with anaemia and iron deficiency in this population. It contributed to low concentrations of haemoglobin, serum iron and serum ferritin and high total iron binding capacity (TIBC). Significant underweight and stunting were associated with low concentrations of haemoglobin and serum iron while significant wasting was significantly associated with low concentration of serum ferritin. Logistic regression analysis confirmed that severe trichuriasis was a strong predictor of IDA. It also confirmed that children who were significantly underweight and whose mother was working were independent predictors of IDA in this population.
