Absorption of non heme iron in typical and standard meals using extrinsically labeled iron 59Fe.

OBJECTIVE: To study the bioavailibility of nonheme iron from standard and test meals in Pakistani adults and to determine iron absorption using extrinsically tagged iron 59Fe. SUBJECTS AND METHODS: Nonheme iron absorption was measured from standard and test meals in ten healthy individuals. Total calories, carbohydrates, proteins, fats, ascorbic acid, total iron, phytate and ascorbic acid content were determined in both meals. Retention of iron was detected by whole body counting using gamma counter before and after administration of standard, test meals and reference dose. RESULTS: Iron absorption with test meal was 13% and after adjustment with serum ferritin and reference dose was 16.5 % and 14% respectively. The absorption of standard meal was 6.7% which after adjustment with serum ferritin and reference dose was 8.8% and 6.9% respectively. The iron and ascorbic acid content of test meal was 6.5 mg and 5.7 mg respectively while phytate phosphorus content was 114 mg. The iron and ascorbic acid content of standard meal was 1.3 mg and 2.4 mg respectively while phytate phosphorus content was 137 mg. CONCLUSION: This evaluated absorption from one of the typical Pakistani diet compared to the standard meal was better. This shows that there are some other physiological factors that lead to iron deficiency anemia in Pakistan.

Preventive strategy to control iron deficiency anemia in children and adults.

OBJECTIVE: To compare improvement in hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin and ferritin levels in children aged 5-10 years and women of reproductive age (15-45) supplemented with daily oral and once weekly with single and double dose of ferrous sulphate. METHOD: Twenty children received 200 mg ferrous sulfate daily and 20 received the same dose once weekly for two months. Ten women received 300 mg ferrous sulfate daily, 10 received the same dose once weekly while 10 received 600 mg of ferrous sulfate once weekly for one month. RESULTS: All parameters improved significantly in children who received 200 mg ferrous sulfate daily and weekly. Similarly, the parameters improved significantly in women who received 300 mg of ferrous sulfate daily and 600 mg of ferrous sulfate weekly. CONCLUSION: Weekly supplementation of iron is far better in controlling iron deficiency anemia due to cost effectiveness and better compliance.

Insulin antibody response to bovine insulin therapy: functional significance among insulin requiring young diabetics in India.

The majority of young diabetics in India prefer to use low-cost bovine insulin for economic reasons. Therefore, the question of insulin antibody response to bovine insulin and its functional significance is still relevant in the Indian context. We assessed insulin antibody response in 52 young diabetics (type 1, n=25, malnutrition modulated form of diabetes, n=19 and fibrocalculous pancreatopathy (FCP) n=8) on bovine insulin therapy (mean duration 3.0+/-2.1 years) using an internationally standardised in-house radioligand assay. The functional significance of insulin antibody was assessed by calculating their affinity constant, maximum binding capacity and total insulin binding power by Scatchard analysis (type 1, n=14, malnutrition modulated form of diabetes, n=11). All the patients treated with bovine insulin showed high titers of insulin antibodies with S.D. score ranging from 5.1 to 42.0. No significant difference was observed in the mean S.D. score of insulin antibodies in the three diabetic groups. The mean daily insulin dose, maximum insulin binding capacity and total insulin binding power were significantly higher in type 1 when compared to the malnutrition modulated form of diabetes (36+/-8 vs. 26+/-11 IU/day, P<0.05; 9. 7+/-7.8 vs. 4.0+/-3.9 nmol/l, P=0.03 and 59+/-29 vs. 29+/-43, P=0.01, respectively). Insulin antibodies S.D. score and its affinity did not show significant relationship with daily insulin dose and glycemic control (HbAl) at admission. Only 24+/-7% variations in daily insulin requirement were accounted for by total insulin binding power. There was a significant inverse relationship between insulin antibody S.D. score and duration of insulin therapy (r=-0. 4172, P<0.0004). To conclude, insulin antibody response following bovine insulin therapy is not different among type 1, malnutrition modulated form of diabetes and FCP diabetes. The insulin antibody response to bovine insulin therapy does not contribute significantly to increase in daily insulin requirement in bovine insulin treated insulin requiring young diabetics.

Insulin autoantibodies before and after carbimazole therapy in Asian Indian patients with Graves' disease.

Carbimazole therapy can induce insulin autoantibodies (IAA) in Japanese Graves' disease patients, a phenomenon possibly linked to their immunogenetic profile. This phenomenon is not observed in Caucasians. We assessed IAA levels in 114 North Indian Graves' disease patients before and after carbimazole therapy (mean duration 6.2 +/- 3.9 months). The functional significance of IAA was assessed in 46 of them by first phase (sum of +1 and +3 min) insulin response to intravenous glucose (IVGTT) and an oral glucose tolerance test (OGTT) undertaken before commencement of the carbimazole therapy. IAA were measured using a radiobinding assay and expressed as the assay precision unit, S.D. scores (S.D.S), over healthy controls. Before treatment 22 of 114 (19.3%) patients were IAA positive (mean +/- S.D., 5.9 +/- 3.2 S.D.S). After carbimazole therapy a further 11 (9.6%) showed positive for IAA (mean +/- S.D., 3.5 +/- 1 S.D.S). Of the 22 patients who were IAA positive before treatment, 12 became negative after carbimazole therapy. The fasting insulin and first phase insulin responses were similar in IAA positive and IAA negative Graves' disease patients (mean +/- S.D., 61.7 +/- 35.9 versus 88.3 +/- 46.6 pmol/l, P = 0.123 and 1127 +/- 696 versus 1033 +/- 430 pmol/l, P = 0.716, respectively). The OGTT results were comparable in the IAA positive and the IAA negative groups. Thus, North Indian Graves' disease patients, who resemble Caucasians in their HLA haplotypes, behave like Japanese in their tendency to become IAA positive with carbimazole therapy. A subset of the patients who were IAA positive before treatment also demonstrated negative IAA (12/22) after carbimazole therapy.

Thrombocytopenia in preeclampsia: an earlier detector of HELLP syndrome.

Platelet count was determined in eighty four pregnant women by direct visual method. Among them thirty normal pregnant women were taken as control. Twenty-seven were preeclamptic and twenty seven eclamptic women. There was significant (P < 0.01) reduction in platelet count of preeclamptic and highly significant (P < 0.001) in eclamptic women as compared to controls. It is concluded that there is need to do platelet count in all pregnancy induced hypertensive women, which can be an earlier detector for HELLP syndrome.
