Expert recommendations for the management of iron deficiency in patients with heart failure in Asia

Sim DKL, Mittal S, Zhang J, Hung CL, Azman WAW, Choi JO, et al.

Int J Cardiol, 2024 May 15;403:131890.
PMID: 38382854 DOI: 10.1016/j.ijcard.2024.131890

BACKGROUND: Iron deficiency is a common comorbidity in heart failure (HF) and is independently associated with a worse quality-of-life and exercise capacity, as well as increased risk of hospitalization, regardless of anemia status. Although international guidelines have provided recommendations for the management of iron deficiency in patients with HF, guidelines in Asia are less established, and practical use of guidelines for management of iron deficiency is limited in the region.
METHODS: A panel comprising cardiologists from China, Hong Kong, India, Japan, Malaysia, Pakistan, Philippines, Singapore, South Korea, Taiwan, and Thailand convened to share insights and provide guidance for the optimal management of iron deficiency in patients with HF, tailored for the Asian community.
RESULTS: Expert opinions were provided for the screening, diagnosis, treatment and monitoring of iron deficiency in patients with HF. It was recommended that all patients with HF with reduced ejection fraction should be screened for iron deficiency, and iron-deficient patients should be treated with intravenous iron. Monitoring of iron levels in patients with HF should be carried out once or twice yearly. Barriers to the management of iron deficiency in patients with HF in the region include low awareness of iron deficiency amongst general physicians, lack of reimbursement for screening and treatment, and lack of proper facilities for administration of intravenous iron.
CONCLUSIONS: These recommendations provide a structured approach to the management of iron deficiency in patients with HF in Asia.

Iron deficiency anemia (IDA) is a major health burden among women in Asia. Key issues in IDA management in Asia are under-diagnosis and under-treatment. The lack of Asia-specific guidelines, and suboptimal utilization of treatment compounds the management of IDA. To address these gaps, a panel of 12 experts in obstetrics, gynecology, and hematology from six regions in Asia convened to review current practices and clinical evidence and provide practical guidance on IDA diagnosis and management in Asian women. The Delphi approach was used to obtain objective opinions and attain consensus on statements pertaining to awareness, diagnosis, and management of IDA. In total, 79 statements attained consensus and are summarized to provide guidance on raising awareness of IDA and approaches for improved diagnosis and treatment of IDA among women in various settings: pregnancy, postpartum, heavy menstrual bleeding, gynecologic cancers, and perioperative care. This clinician-led consensus integrates appropriate recommendations based on clinical evidence and best practices and is intended to guide decision making in the management of iron deficiency/IDA in women. The expert panel raises a call for timely diagnosis and utilization of appropriate treatment, including use of high-dose intravenous iron, stringent blood management, and interdisciplinary collaboration, for optimization of IDA management among women in Asia.

Iron overload in anaemia with underlying haemoglobin constant spring in an antenatal mother in primary care

Thew HZ, Ng CH, Loo CY

BMJ Case Rep, 2024 Feb 17;17(2).
PMID: 38367998 DOI: 10.1136/bcr-2023-258526

This is the case of a gravida 3 para 1 woman in her late 20s with underlying haemoglobin constant spring who visited a healthcare clinic for an antenatal check-up. Towards the end of her second trimester, she experienced lethargy. During her antenatal booking, she was diagnosed with mild asymptomatic anaemia, high serum ferritin, T saturation of 88% and abnormal liver function tests. She was referred to a hospital where an MRI scan revealed over 2 g of iron deposits in her liver, leading to a revised diagnosis of iron overload. Treatment included deferoxamine and expectant management throughout her antenatal period, and her delivery was uncomplicated. While iron deficiency anaemia is common in pregnancy, it is crucial not to overlook iron deposition and the distinction from acute fatty liver during pregnancy to prevent treatment delays.

Fulltext Effects of iron supplementation and nutrition education on haemoglobin, ferritin and oxidative stress in iron-deficient female adolescents in Palestine: randomized control trial

Jalambo M, Karim N, Naser I, Sharif R

East Mediterr Health J, 2018 Jul 29;24(6):560-568.
PMID: 30079951 DOI: 10.26719/2018.24.6.560

Background: Iron deficiency and iron-deficiency anaemia are associated with oxidative stress, but their role is largely unclear. Information is scarce on the effects of iron supplementation on biomarkers of oxidative stress in humans.
Aims: This study evaluated the effectiveness of iron supplementation and nutrition education on improving the levels of haemoglobin and ferritin, and decreasing oxidative stress among iron-deficient female adolescents in Gaza, Palestine.
Methods: A total 131 iron-deficient female adolescents were recruited and allocated randomly into 3 different groups. The iron supplementation group (A) received 200 mg of ferrous fumarate weekly during the 3-month intervention, the iron supplementation with nutrition education group (B) received iron supplements with nutrition education sessions, and the control group (C) did not receive any intervention. The levels of haemoglobin, ferritin and malonyl dialdehyde were measured at baseline, after 3 months (at which point the intervention was stopped), and then 3 months later. Trial registration number: ACTRN12618000960257.
Results: Haemoglobin levels increased significantly after supplementation in both groups A and B. At the follow-up stage (3 months after stopping the intervention), iron and haemoglobin levels in group B continued to increase and malonyl dialdehyde decreased. In Group A, haemoglobin, ferritin and malonyl dialdehyde levels decreased after 3 months of stopping the intervention. No changes were seen in Group C.
Conclusions: A nutrition programme should be adopted and integrated into comprehensive intervention programmes to target iron-deficiency anaemia among female adolescents in Palestine.

Iron deficiency is the commonest cause of anemia worldwide and healthy blood donors are estimated to lose about 236 mg of iron with each donation. The objective of this study was to determine the serum ferritin levels among first time and regular male blood donors, and also to correlate the serum ferritin levels with the number of donations and hemoglobin levels. Hemoglobin levels and serum ferritin were measured in three groups of donors divided into first time donors; (n = 92), donors with 2-4 donations (n = 41), and regular donors (n = 78). The mean hemoglobins in the first time donors, second group and regular blood donor group were 14.95 +/- 1.08, 15.12 +/- 1.44 and 15.56 +/- 1.48, respectively. The serum ferritin level were found to be significantly lower among the regular donors (62.0 +/- 39.78 ng/ml) compared to first time donors (90.7 +/- 66.63) and second group donors (114.12 +/- 66.97). The serum ferritin levels gradually decrease according to the number of donations and there was a significant correlation between frequency of donations and the serum ferritin level (r2 = 0.082). Significant correlation between the number of donations and hemoglobin level r2 = 0.061) was noted. However, there was no significant correlation between hemoglobin and serum ferritin levels (r2 = 0.015). Eleven percent of regular donors had depleted iron stores. This was not noted in donors who donated less than 5 times within 2 years.

Tee ES, Kandiah M, Awin N, Chong SM, Satgunasingam N, Kamarudin L, et al.

Am J Clin Nutr, 1999 Jun;69(6):1249-56.
PMID: 10357747 DOI: 10.1093/ajcn/69.6.1249

BACKGROUND: Iron deficiency and its consequent anemia constitute the commonest micronutrient deficiency in the world.
OBJECTIVE: We investigated whether long-term, weekly iron-folate supplements administered at school would improve hemoglobin and ferritin concentrations in adolescent girls, including those with mild-to-moderate anemia and hemoglobin concentrations indicating borderline anemia.
DESIGN: Subjects were 266 girls with hemoglobin concentrations of 80-119.9 g/L (group A) and 358 girls with hemoglobin concentrations of 120-130 g/L (group B) who were otherwise healthy. Two hundred sixty-six girls in group A and 268 girls in group B were randomly assigned to receive either 60 or 120 mg Fe plus 3.5 mg folic acid weekly for 22 wk. Ninety of the girls in group B were randomly assigned to receive only 5 mg folic acid weekly. Capillary hemoglobin and plasma ferritin were measured at baseline and after 12 and 22 wk of supplementation.
RESULTS: By the end of the study, 2% of the girls had dropped out and > 96% had taken > or = 20 of the 22 tablets; side effects were minimal. Mean plasma ferritin increased significantly in all iron-supplemented groups, independently of initial hemoglobin values and iron doses. Ferritin concentrations decreased in the girls supplemented with folic acid only. As expected, hemoglobin responses to iron were higher in group A than in group B and increases were positively correlated with initial plasma ferritin. Hemoglobin failed to respond to folate supplementation if initial plasma ferritin concentrations were low. Mean hemoglobin increased significantly and consistently in relation to the length of treatment.
CONCLUSION: Long-term, weekly iron-folate supplementation was found to be a practical, safe, effective, and inexpensive method for improving iron nutrition in adolescent schoolgirls.
