Differential Diagnosis for Low Iron, Normal TIBC and Ferritin with Low H and H

  • Single most likely diagnosis:
    • Anemia of Chronic Disease (ACD): This condition is characterized by low iron levels, normal or decreased Total Iron-Binding Capacity (TIBC), and elevated or normal ferritin levels. The presence of low hemoglobin (H) and hematocrit (Hct) supports this diagnosis, as ACD often leads to a decrease in these parameters due to the body's inability to effectively utilize iron for erythropoiesis.
  • Other Likely diagnoses:
    • Chronic Kidney Disease (CKD): CKD can lead to a decrease in erythropoietin production, resulting in anemia. While ferritin levels may be normal, the inflammation associated with CKD can cause a decrease in iron availability, leading to low iron levels.
    • Inflammatory Bowel Disease (IBD): IBD, including conditions like Crohn's disease and ulcerative colitis, can cause chronic inflammation, leading to anemia of chronic disease. The normal TIBC and ferritin levels, combined with low iron and low H and H, are consistent with this diagnosis.
  • Do Not Miss (ddxs that may not be likely, but would be deadly if missed.):
    • Hemochromatosis with Iron Depletion: Although hemochromatosis typically presents with elevated iron stores, advanced disease can lead to iron depletion due to repeated phlebotomies or other factors. Missing this diagnosis could result in delayed treatment and increased risk of complications.
    • Thalassemia Major: This genetic disorder can cause severe anemia, and while it typically presents with low ferritin and high TIBC, some cases may have normal TIBC and ferritin levels. Missing this diagnosis could lead to delayed or inadequate treatment.
  • Rare diagnoses:
    • Pyridoxine-responsive anemia: This rare condition is characterized by anemia, low iron levels, and normal TIBC and ferritin levels. It responds to pyridoxine (vitamin B6) supplementation.
    • Aceruloplasminemia: A rare genetic disorder causing iron accumulation in tissues, which can lead to anemia, low iron levels, and normal TIBC and ferritin levels.
