1. Serum prealbumin, transferrin and iron concentrations were measured in ninety-two north Cameroonian children under 5 years of age. The results were grouped according to the blood haemoglobin concentration range in order to show the interactions of anaemia with prealbumin and transferrin concentrations.2. Transferrin concentration showed a significant negative correlation with serum Fe and percentage saturation of transferrin values. Prealbumin concentration showed a significant direct correlation with haemoglobin but did not correlate with either serum Fe or percentage saturation of transferrin.3. It is concluded that in regions where Fe-deficiency anaemia is endemic transferrin concentration may be of little value in determining nutritional status. On the contrary, prealbumin seems to be more useful.

AbstractBackgroundBlood loss from the gastrointestinal (GI) tract is the most common cause of iron deficiency anaemia (IDA) in adult men and postmenopausal women. Gastroduodenal endoscopy (GDE) and colonoscopy are frequently recommended, despite uncertainty regarding the coexistence of lesions in the upper and lower GI tract. The faecal immunochemical test (FIT) measures the concentration of faecal haemoglobin (f-Hb) originating only from the colon or rectum. We aimed to assess whether the FIT was able to select the best endoscopic procedure for detecting the cause of IDA.MethodsA prospective study of 120 men and postmenopausal women referred for a diagnostic study of IDA were evaluated with an FIT, GDE and colonoscopy. The endoscopic finding of a significant upper lesion (SUL) or a significant bowel lesion (SBL) was considered to be the cause of the IDA.ResultsThe diagnoses were 35.0% SUL and 20.0% SBL, including 13.3% GI cancer. In the multivariate analysis, the concentration of blood haemoglobin (b-Hb) <9 g/dL (OR: 2.60; 95% CI 1.13–6.00; p = 0.025) and non-steroidal anti-inflammatory drugs NSAIDs (2.56; 1.13–5.88; p = 0.024) were associated with an SUL. Age (0.93; 0.88–0.99; p = 0.042) and f-Hb ≥ 15 μg Hb/g faeces (38.53; 8.60–172.50; p < 0.001) were associated with an SBL. A “FIT plus gastroscopy” strategy, in which colonoscopy is performed only when f-Hb ≥15 μg Hb/g faeces, would be able to detect 92.4% of lesions and be 100% accurate in the detection of cancer while avoiding 71.6% of colonoscopies.ConclusionsThe FIT is an accurate method for selecting the best endoscopy study for the evaluation of IDA. An FIT-based strategy is more cost-effective than the current bidirectional endoscopy-based strategy and could improve endoscopic resource allocation.

1. Measurements of transfer factor and sub-maximal exercise ventilation and cardiac frequency have been made on twenty women with iron-deficiency anaemia (Hb 8–9 g/100 ml) before and after ‘treatment’ with iron or placebo tablets and on control subjects. 2. The exercise ventilation, cardiac frequency and oxygen uptake were independent of haemoglobin concentration but the transfer factor was lower in the test than in control subjects and was increased by iron but not by placebo treatment. The results support the validity of the reaction-rate data for carbon monoxide with oxyhaemoglobin of Roughton & Forster (1957) despite evidence to the contrary from other studies. 3. In interpretation of sub-maximal exercise ventilation and cardiac frequency in iron-deficiency anaemia no allowance need be made for variation in haemoglobin concentration in the range 8–15 g/100 ml. For transfer factor a correction should be made by using a variant of the relationship of Roughton & Forster (1957).

Background: Prevalence of iron deficiency anaemia is high in developing countries like India. Treatment of iron deficiency anaemia in pregnancy is very important to bring down maternal mortality rate as blood loss during delivery can lead to death of the patient. The aim and objective of our study is to evaluate the efficacy and safety of intravenous iron sucrose infusions in antenatal women admitted in hospital suffering from moderate iron deficiency anaemia. Special emphasis was given to observe adverse drug effects.Methods: This was a prospective observational study conducted in Obstetrics and Gynaecology department, Government General Hospital, Rangaraya Medical College, Kakinada, Andhra Pradesh. Study period was two months and study population included antenatal women with gestational age less than 37 weeks with moderate iron deficiency anaemia. Peripheral smear was examined for microcytic hypochromic anaemia and they were treated with intravenous infusion of iron sucrose. Haemoglobin levels were checked before and 5 weeks after iron infusions. Monitoring was done for adverse reactions.Results: Out of 322 admissions, 95% were found to be anaemic. 72 patients were suffering from moderate anaemia from which 25 have been included and treated with intravenous iron sucrose infusions. They were observed for efficacy and safety parameters. Two minor adverse events were reported (fever with chills and angioedema of lips) and they were excluded from study. Mean haemoglobin concentration was found to be raised from 7.08±0.73 (SD) to 11.33±0.48 (SD) within 5 weeks for 23 patients.Conclusions: Iron sucrose infusion is safe and effective for anaemia in pregnancy.

BackgroundIron-deficiency anaemia disproportionately affects children in low-income and middle-income areas; Western China is a prime example. Given the health risks associated with childhood anaemia and the large heterogeneity of published studies on this subject, we conducted a systematic review of the evidence regarding anaemia prevalence and associated factors in children under 5 years in Western China.MethodsWe searched for all relevant studies on the prevalence of iron deficiency anaemia in children under 5 years in Western China, obtaining research between 1 January 2011 and 30 June 2021, in English and Chinese from Medline, Embase, PubMed, Web of Science, CNKI, WanFang Data and VIP. Two reviewers independently screened titles and abstracts; three reviewed full texts of relevant articles for data extraction and performed quality assessments. The median prevalence was calculated on unweighted pooling, stratified by region, sex, age and ethnic group. Associated factors and a linear trend chart were conducted to identify trends and research highlights.ResultsAmong the 55 articles included, most were cross-sectional studies (39, 70.91%). The prevalence of anaemia in children under 5 years in Western China ranged from 3.69% to 75.74% (median 42.54% (IQR 25.62%–52.56%)); the highest levels were in Qinghai province: 59.10%–75.74% (median 67.80% (IQR 64.70%–72.75%)); the highest levels were reported in the subgroup of children aged 6–12 months (median 50.09% (IQR 34.35%–59.04%)). Regional contexts, individual sociodemographic characteristics and feeding behaviours, and nutritional programme interventions were factors associated with anaemia prevalence.ConclusionThe prevalence of anaemia in children under 5 years in Western China is concerningly high. For this multiethnic and economically underdeveloped region, more high-quality and prospective studies are needed to inform evidence based and targeted preventive strategies to decrease the high prevalence of anaemia among young children.

ObjectiveTo refine and validate a model for predicting the risk of gastrointestinal (GI) cancer in iron deficiency anaemia (IDA) and to develop an app to facilitate use in clinical practice.DesignThree elements: (1) analysis of a dataset of 2390 cases of IDA to validate the predictive value of age, sex, blood haemoglobin concentration (Hb), mean cell volume (MCV) and iron studies on the probability of underlying GI cancer; (2) a pilot study of the benefit of adding faecal immunochemical testing (FIT) into the model; and (3) development of an app based on the model.ResultsAge, sex and Hb were all strong, independent predictors of the risk of GI cancer, with ORs (95% CI) of 1.05 per year (1.03 to 1.07, p<0.00001), 2.86 for men (2.03 to 4.06, p<0.00001) and 1.03 for each g/L reduction in Hb (1.01 to 1.04, p<0.0001) respectively. An association with MCV was also revealed, with an OR of 1.03 for each fl reduction (1.01 to 1.05, p<0.02). The model was confirmed to be robust by an internal validation exercise. In the pilot study of high-risk cases, FIT was also predictive of GI cancer (OR 6.6, 95% CI 1.6 to 51.8), but the sensitivity was low at 23.5% (95% CI 6.8% to 49.9%). An app based on the model was developed.ConclusionThis predictive model may help rationalise the use of investigational resources in IDA, by fast-tracking high-risk cases and, with appropriate safeguards, avoiding invasive investigation altogether in those at ultra-low predicted risk.

Using a systematic review method, the prevalence of anaemia, iron deficiency (ID), and iron deficiency anaemia (IDA) in women of reproductive age (WRA) and children under 5 years of age was obtained to inform priorities in health planning and policy in South Africa. We searched electronic databases for articles published between 1997 and 2021. A total of 713 articles were identified, of which 14 articles comprising 9649 WRA and 4085 children were included. Since most of the included studies were of low quality, we did not pool data in a meta-analysis due to heterogeneity (I2 > 75%). In WRA, anaemia prevalence ranged from 22.0% to 44.0%; ID from 7.7% and 19.0%; and IDA from 10.5% to 9.7%. The prevalence of anaemia in pregnancy was 29.0% to 42.7%; and 60.6% to 71.3% in HIV-infected pregnant women. Three national surveys reported anaemia in children at 28.9%, 10.7%, and 61.3%, respectively. Overall, among the children under 5 years old, anaemia was more prevalent in 1-year-olds (52.0%) compared to the other age groups. Between 2005 and 2012, ID increased by 3.8% and IDA decreased by 83.2% in children. Anaemia in WRA and children under 5 years in South Africa was a moderate public health concern. Therefore, interventions addressing anaemia should be intensified, and policies on iron supplementation and food fortification need to be revised and aligned to the WHO multiple micronutrient supplementation recommendations.

BACKGROUND An iron infusion pathway using Ferrinject®(ferric carboxymaltose) was implemented at Southend University Hospital for pre-operative surgical patients with iron deficiency anaemia undergoing major surgery. This was based on a treatment algorithm proposed by Munting et al, based on the international consensus statement on peri-operative management of anaemia and NICE guidelines. This states intravenous iron is indicated when oral iron is poorly tolerated, ineffective, there is insufficient time to surgery, or due to functional iron deficiency. OBJECTIVE Our objective was to study the degree of change in adult haemoglobin concentration (Hb g/L) after infusion at the time of surgery. METHODS Data was retrospectively collected on all surgical patients that received an iron infusion pre-operatively for iron deficiency anaemia from July 2019 to April 2020. Non-surgical patients, obstetrics, paediatrics and those without a post infusion haemoglobin level were excluded. Data collected included: pre and post infusion Hb, ferritin, and transferrin (post infusion results closest to surgery were collected), correct or incorrect dose of IV iron received (dose based on baseline Hb and weight) and any adverse reactions noted. RESULTS 32 surgical patients with iron deficiency anaemia received intravenous iron between July 2019 and April 2020 prior to surgery. The average pre and post iron infusion haemoglobin concentration across the cohort was 97 g/L and 114 g/L respectively (18% increase p= 0.001). 2 (6%) patients had a post transfusion Hb ≥ 130 g/L prior to surgery after infusion. 9 patients had both a pre and post infusion ferritin level recorded which showed an increase from 12 μg/L pre infusion to 94 μg/L (p=0.02) post infusion. 23 (72%) patients were did not receive the full dose of IV iron based on their Hb and weight. 75% of patients received an iron infusion >2 weeks prior to surgery with 25% < 2 weeks before their surgery. There was an average increase in Hb of 22% (21 g/L 95% CI 13-28) and 5% (5 g/L 95% CI 1-10) (p=0.03) respectively across the two groups. There were no documented adverse reactions to the infusion. CONCLUSIONS IV iron is an effective intervention to improve haemoglobin concentration in iron deficiency anaemia despite the majority of cases not receiving the full dose of IV iron based on their baseline Hb and weight. Increasing interval time between infusion and surgery was associated with a greater increase in Hb with only a minimal increase seen if given less than 2 weeks before.
