Abstract Background: Serum transferrin receptor (sTfR) concentrations are increased in iron deficiency. We wished to examine whether they are decreased in the presence of potential iron-loading conditions, as reflected by increased transferrin saturation (TS) on a single occasion. Methods: We compared sTfR concentrations between 570 controls with normal iron status and 189 cases with increased serum TS on a single occasion; these latter individuals may be potential cases of iron overload. Cases and controls were selected from adults who had been examined in the third National Health and Nutrition Examination Survey (1988–1994) and for whom excess sera were available to perform sTfR measurements after the survey’s completion. Increased TS was defined as >60% for men and >55% for women; normal iron status was defined as having no evidence of iron deficiency, iron overload, or inflammation indicated by serum ferritin, TS, erythrocyte protoporphyrin, and C-reactive protein. Results: Mean sTfR and mean log sTfR:ferritin were ∼10% and 24% lower, respectively, in cases than in controls (P <0.002). Cases were significantly more likely to have an sTfR value <2.9 mg/L, the lower limit of the reference interval, than were controls (odds ratio = 1.8; 95% confidence interval, 1.04–2.37). Conclusion: Our results support previous studies that suggested that sTfR may be useful for assessing high iron status in populations.

The Mean

Objectives. Sickle cell anaemia (SCA) is one of the commonest genetic disorders in the world. It is characterized by anaemia, periodic attacks of thrombotic pain, and chronic systemic organ damage. Recent studies have suggested that individuals with SCA especially from developing countries are more likely to be iron deficient rather than have iron overload. The study aims to determine the iron status of SCA patients in Ilorin, Nigeria.Methods. A cross-sectional study of 45 SCA patients in steady state and 45 non-SCA controls was undertaken. FBC, blood film, sFC, sTfR, and sTfR/log sFC index were done on all subjects.Results. The mean patients’ serum ferritin (589.33 ± 427.61 ng/mL) was significantly higher than the mean serum ferritin of the controls (184.53 ± 119.74 ng/mL). The mean serum transferrin receptor of the patients (4.24 ± 0.17 μg/mL) was higher than that of the controls (3.96 ± 0.17 μg/mL) (p=0.290). The mean serum transferrin receptor (sTfR)/log serum ferritin index of the patients (1.65 ± 0.27 μg/mL) was significantly lower than that of the control (1.82 ± 0.18 μg/mL) (p=0.031).Conclusion. Iron deficiency is uncommon in SCA patients and periodic monitoring of the haematological, biochemical, and clinical features for iron status in SCA patients is advised.

Despite the established utility of serum transferrin receptor (sTfR), serum ferritin, and the sTfR/log ferritin ratio (TfR-F Index) in the diagnosis of iron deficiency (ID) anemia, the numeric values of these parameters, which are indicative of subclinical ID, remain to be clearly defined. In this study, 65 apparently healthy nonanemic adults (22 men and 43 women) were treated with 3 months of oral iron supplementation to evaluate its effect on parameters reflecting iron status and to determine the prevalence of subclinical iron deficiency in apparently healthy adults. Significant supplementation-induced changes were observed in sTfR, ferritin, and TfR-F Index values in women, whereas in men, none of the studied parameters showed any significant change. Iron-deficient erythropoiesis (IDE) was not observed in men, but was found in 17 women (40%). Although individuals with a compromised iron status may be represented in substantial numbers in conventional reference populations, they can be readily identified using sTfR, ferritin, and TfR-F Index determinations. © 1998 by The American Society of Hematology.

Abstract This study was undertaken to evaluate the role of serum transferrin receptor measurements in the assessment of iron status. Repeated phlebotomies were performed in 14 normal volunteer subjects to obtain varying degrees of iron deficiency. Serial measurements of serum iron, total iron-binding capacity, mean cell volume (MCV), free erythrocyte protoporphyrin (FEP), red cell mean index, serum ferritin, and serum transferrin receptor were performed throughout the phlebotomy program. There was no change in receptor levels during the phase of storage iron depletion. When the serum ferritin level reached subnormal values there was an increase in serum receptor levels, which continued throughout the phlebotomy program. Functional iron deficiency was defined as a reduction in body iron beyond the point of depleted iron stores. The serum receptor level was a more sensitive and reliable guide to the degree of functional iron deficiency than either the FEP or MCV. Our studies indicate that the serum receptor measurement is of particular value in identifying mild iron deficiency of recent onset. The iron status of a population can be fully assessed by using serum ferritin as a measure of iron stores, serum receptor as a measure of mild tissue iron deficiency, and hemoglobin concentration as a measure of advanced iron deficiency.
