An Iron Deficency Anemia
using the format build a soaMp note with scholarly references no older than 5 years for an Adult female with an iron defficency anemia, using scholarly refenrences to support diagnosis and differential diagnosis.
Answer:
Subjective: The patient is a 35-year-old female presenting with symptoms of fatigue, weakness, and shortness of breath. She reports a recent onset of pale skin and brittle nails. The patient denies any recent illness, gastrointestinal bleeding, or significant changes in diet. She reports heavy menstrual periods over the past few months. She has a history of chronic kidney disease and takes medication for hypertension.
Objective:
- Vital signs: BP 130/80 mmHg, HR 90 bpm, RR 18 breaths/min, Temp 98.6°F
- Physical examination reveals pale conjunctiva and skin pallor.
- Laboratory findings:
- Hemoglobin: 9.5 g/dL (normal range: 12-16 g/dL)
- Hematocrit: 30% (normal range: 36-48%)
- Mean corpuscular volume (MCV): 70 fL (normal range: 80-100 fL)
- Serum iron: 20 mcg/dL (normal range: 60-160 mcg/dL)
- Ferritin: 10 ng/mL (normal range: 12-150 ng/mL)
- Total iron-binding capacity (TIBC): 450 mcg/dL (normal range: 250-400 mcg/dL)
- Transferrin saturation: 5% (normal range: 20-50%)
Assessment: The patient’s clinical presentation and laboratory findings are consistent with iron deficiency anemia (IDA). The low hemoglobin, hematocrit, MCV, serum iron, ferritin, and transferrin saturation levels indicate insufficient iron stores and impaired red blood cell production.
Differential Diagnosis:
- Chronic Kidney Disease (CKD): The patient’s history of CKD may contribute to anemia due to decreased erythropoietin production and impaired iron metabolism.

- Gastrointestinal Bleeding: Although denied by the patient, occult gastrointestinal bleeding should be considered as a potential cause of IDA, especially in the absence of other risk factors.
- Reference: Rockey, D. C. (2019). Occult gastrointestinal bleeding. New England Journal of Medicine, 381(7), 673-683.
- Menorrhagia: Heavy menstrual bleeding reported by the patient is a common cause of iron deficiency anemia in premenopausal women.

Plan:
- Iron supplementation: Initiate oral ferrous sulfate 325 mg three times daily with vitamin C to enhance absorption.
- Treat underlying cause: Address management of chronic kidney disease and consider referral to a nephrologist for further evaluation.
- Monitor response to treatment: Repeat complete blood count and iron studies in 4-6 weeks to assess for improvement in hemoglobin and iron levels.
- Patient education: Provide information on dietary sources of iron and reinforce compliance with iron supplementation therapy.
