Iron Deficiency Anemia & Microcytic Anemias

🔬 Practice‑Changing Findings
Evidence from RCTs and meta‑analyses published in the last 12 months.

1. Efficacy of daily versus alternate day oral iron supplementation for management of anaemia among general population: a systematic review and meta-analysis.

BMC Pharmacology & Toxicology (2025) - Systematic Review/Meta-analysis

Key Findings

  • Alternate-day oral iron showed similar hemoglobin improvement versus daily dosing across pooled studies.
  • GI side effects were reduced versus daily schedules in multiple comparisons, supporting better treatment persistence.

📋 Practice Implication: For uncomplicated outpatient IDA, start or switch to alternate-day oral iron when adherence is limited by nausea, constipation, or abdominal discomfort.

2. The effect of intravenous iron supplementation compared to oral iron supplementation during pregnancy on neonatal outcomes-a systematic review of randomized controlled trials.

European Journal of Pediatrics (2025) - Systematic Review/Meta-analysis of RCTs

Key Findings

  • Intravenous iron produced greater maternal hematologic correction versus oral iron in pregnancy-focused randomized data.
  • Neonatal outcomes were generally similar versus oral strategies, while maternal repletion improved more reliably in moderate-to-severe anemia.

📋 Practice Implication: In prenatal primary care, move to IV iron earlier for moderate/severe IDA or oral-treatment failure instead of extending ineffective oral courses.

3. Executive Summary of the KDIGO 2026 Clinical Practice Guideline for the Management of Anemia in Chronic Kidney Disease (CKD).

Kidney International (2026) - Practice Guideline

Key Findings

  • The 2026 KDIGO update recommends tighter hemoglobin-plus-iron parameter monitoring to guide CKD anemia treatment decisions.
  • Guideline-directed iron repletion thresholds and coordinated ESA decisions improved consistency versus ad hoc CKD anemia management.

📋 Practice Implication: For CKD patients in family medicine, standardize ferritin/TSAT surveillance intervals and trigger nephrology referral using guideline-based anemia thresholds.

4. Intravenous ferric carboxymaltose in patients with heart failure and iron deficiency: a systematic review and meta-analysis of randomized controlled trials with trial sequential analysis.

ESC Heart Failure (2026) - Systematic Review/Meta-analysis of RCTs

Key Findings

  • In iron-deficient heart-failure populations, ferric carboxymaltose improved functional outcomes versus control care in pooled randomized evidence.
  • Heart-failure event burden and hospitalization-related endpoints were reduced versus comparators in updated aggregate analyses.

📋 Practice Implication: In chronic HF follow-up, routinely screen iron status and refer eligible iron-deficient patients for IV ferric carboxymaltose pathways to reduce decompensation risk.

5. Preoperative intravenous versus oral iron supplementation for elective surgery: evidence based on 12 randomized trials.

Postgraduate Medicine (2025) - Systematic Review/Meta-analysis of RCTs

Key Findings

  • Preoperative IV iron improved perioperative hemoglobin and iron indices versus oral iron in pooled elective-surgery trials.
  • Transfusion exposure trended lower versus oral strategies when anemia was addressed early before surgery.

📋 Practice Implication: When PCPs detect pre-op iron-deficiency anemia, fast-track infusion-center treatment planning rather than relying on short-window oral repletion.

💡 Summary

Recent evidence supports practical shifts in primary-care iron-deficiency management: alternate-day oral iron can preserve efficacy while improving tolerability, and earlier escalation to IV iron is beneficial in selected high-risk groups. Updated guideline and meta-analytic data also support more systematic ferritin/TSAT-based screening in chronic disease populations. Overall, the most practice-changing move is proactive identification and targeted treatment rather than prolonged empiric oral retries.
