Understanding Elevated CBC Levels After Iron Infusion for IDWA: Is It Normal?

Since 2020, I have encountered persistent issues with low iron levels. Despite years of oral iron supplementation, my iron status remained within the lower range, coupled with a declining transferrin saturation (tsat). Interestingly, my red blood cell (RBC) count has consistently hovered around the upper limit of normal, occasionally exceeding that threshold. To provide some context, I am diagnosed with a metabolic disorder, and my A1c levels have shown improvement over the past five years compared to earlier periods, resulting in a somewhat reduced experience of fatigue overall. In September, I contracted COVID-19 for the first time, which brought on extreme fatigue alongside weakness, muscle pain, and headaches as the predominant symptoms. A month after recovering, I began experiencing severe gastrointestinal (GI) issues that persisted long after the virus resolved. Eventually, sharp pain in my upper left abdomen prompted an ultrasound, which led to a fibroscan owing to indications of fatty infiltration in the liver, a consequence of my metabolic condition. Given that I had my gallbladder removed 25 years ago, that was ruled out as a cause. Both the ultrasound and fibroscan did not reveal other abnormalities, with the fibroscan yielding a liver stiffness score of 5.7 kPa, indicating a fibrosis stage of F0-F1. Throughout this ordeal, I have dealt with considerable fatigue and cognitive fog. Consequently, I sought the expertise of both a GI specialist and a hematologist to explore potential underlying causes for my fatigue and GI challenges. The hematologist advised me to cease oral iron and proceed with an iron infusion, a course supported by both specialists, with a follow-up endoscopy planned if my iron levels did not improve. In December, my tsat was recorded at 11%, and the infusion took place at the end of January. Post-infusion, I have not observed any significant improvement; instead, my brain fog has intensified, headaches have worsened, and some days, my fatigue is nearly incapacitating. In February, my ferritin level reached 620, while tsat increased to 14%. Astonishingly, all other lab results remained normal. The hematologist noted that my body might be consuming iron stores more rapidly than expected and suggested re-evaluating my labs one month later, which I did this week. The results revealed a ferritin level of 473, a drop in tsat back to 11%, and elevated counts across RBC, white blood cells (WBC), hematocrit, and hemoglobin, exceeding the normal range. Apologies for the lengthy context; my question is: Is it common for these CBC counts to rise after an iron infusion, particularly when I experienced low iron but not anemia? Is it feasible for them to temporarily exceed normal levels due to increased ferritin? Alternatively, should I be concerned about conditions such as polycythemia, possibly arising from the other factors at play? Of course, I will follow up with my hematologist and await their response, but I am eager for additional insights and inquiries I should consider. For years, my endocrinologist has been my primary evaluator, yet now the input from various specialists, while beneficial, adds a layer of complexity to my health management.

Thank you for sharing such a detailed account of your health journey. From what you've described, it appears you've been navigating a complex set of challenges related to your iron levels, metabolic condition, and post-viral symptoms. To address your key concerns, let's discuss the effects of iron infusion on your complete blood count (CBC) levels and what might be happening with your elevated counts.

Main Points:

• It is not uncommon for CBC levels, including RBC, WBC, hemoglobin, and hematocrit, to increase after an iron infusion, especially if your body is responding to the additional iron stored.
• Elevated CBC counts could be a result of various factors, such as stress on the body, hydration levels, or inflammatory responses, rather than solely indicative of polycythemia.

Explanation: When you receive an iron infusion, your body can indeed utilize the additional iron to produce more red blood cells, which may lead to increased counts. Iron infusions can sometimes cause transient changes in your blood parameters, particularly if your body is actively adjusting to the new iron levels. However, these changes also depend on other factors, such as hydration, other underlying health conditions, or stress responses, which can influence CBC values.

Polycythemia, characterized by elevated red blood cell mass, can be primary (due to intrinsic bone marrow problems) or secondary (due to factors such as chronic low oxygen levels). Given your metabolic condition and recent health challenges, it’s important to monitor these elevated counts closely. While this might not be the most pressing concern right now, continued evaluation with your hematologist is crucial.

Next Steps:

1. Follow-Up with Your Hematologist: Keep your scheduled appointments and express your concerns about the elevated CBC levels. They may suggest further evaluations or monitoring to determine the cause.

2. Monitor Symptoms: Pay attention to how your symptoms develop, such as fatigue, cognitive fog, or headaches. Document any changes to discuss with your healthcare providers.

3. Hydration and Nutrition: Ensure you're staying well-hydrated, as dehydration can affect blood counts. A balanced diet, rich in iron (with physician approval), can aid in managing your overall health.

4. Assess Other Symptoms: If you notice any new symptoms or significant worsening, report these promptly to your healthcare provider.

5. Education and Inquiry: Continue your research and ask questions during your appointments, focusing on how your metabolic disorder might be influencing your lab results.

It's understandable to feel overwhelmed by the interplay between multiple specialists and your ongoing symptoms. Remember, you are not alone in this journey, and it’s good to advocate for your health needs. Please take care of yourself, and feel free to reach out if you have more inquiries or need further clarification.
