From the Guidelines

Mild anemia, as indicated by low RBC count, hemoglobin, and hematocrit, should be managed by treating the underlying cause, and iron supplementation should be initiated when iron deficiency anemia is present, with a preferred dose of 100 mg/day iron sulphate for patients with mild anemia (Hb ≥ 10 g/dL) 1.

Key Considerations

  • The approach to treatment depends mainly on symptoms, the severity of anemia, and etiology 1.
  • Treating the underlying cause, such as chronic inflammation in ulcerative colitis, is the first step in managing anemia 1.
  • Iron supplementation can be administered orally, intramuscularly, or intravenously, with the choice of method determined by symptoms, etiology, and severity of the condition 1.
  • Regular follow-up blood tests should be conducted to monitor response to treatment, with intervals of 3 months for 1 year, then after a further year, and again if symptoms of anemia develop after that 1.

Management Strategies

  • Dietary modifications to increase iron intake through foods like red meat, beans, and leafy greens, along with vitamin C to enhance iron absorption.
  • Iron supplementation with ferrous sulfate 325 mg taken 1-3 times daily between meals with vitamin C.
  • Other supplements may be needed based on the specific deficiency, such as vitamin B12 (1000 mcg daily) or folate (1 mg daily).
  • Patient education on anemia symptoms like fatigue, weakness, and shortness of breath, and when to seek medical attention if symptoms worsen.

Monitoring and Follow-up

  • Regular follow-up blood tests to monitor response to treatment and adjust therapy as needed.
  • Monitoring of hemoglobin levels, red cell indices, and ferritin concentrations to assess iron stores and anemia severity.
  • Further investigation only necessary if the hemoglobin and red cell indices cannot be maintained with treatment 1.

From the Research

Management of Mild Anemia

The patient's laboratory results indicate mild anemia, as evidenced by low RBC count, hemoglobin, and hematocrit. To manage this condition, the following steps can be taken:

  • Conduct a thorough history and physical examination to investigate the cause of anemia, as suggested by 2
  • Perform a complete blood cell count (CBC) and examine the mean corpuscular volume to provide important clues to the classification and cause of anemia, as recommended by 2
  • Consider supplemental tests, such as:
    • Peripheral blood smear
    • Reticulocyte count
    • Iron panel (ie, ferritin and iron levels, total iron-binding capacity, transferrin saturation)
    • Levels of vitamin B12, folate, lactate dehydrogenase, haptoglobin, and bilirubin, as mentioned in 2
  • Approach the clinical and laboratory evaluation logically, using the complete blood count with red cell indices to offer clues to diagnosis, as suggested by 3
  • Use the reticulocyte count as a useful screen for hemolysis or blood loss, as recommended by 3
  • Perform testing for specific causes of the anemia, and occasionally, examination of the bone marrow may be required for diagnosis, as mentioned in 3

Diagnostic Tests

The following diagnostic tests can be used to determine the etiology of the patient's anemia:

  • Complete blood count with red cell indices
  • Reticulocyte count
  • Peripheral blood smear
  • Iron panel
  • Molecular testing, as discussed in 3
  • Bone marrow examination, if necessary, as mentioned in 3

Classification and Cause of Anemia

Careful examination of the CBC and the mean corpuscular volume can provide important clues to the classification and cause of anemia, as suggested by 2. The patient's laboratory results, including low RBC count, hemoglobin, and hematocrit, can be used to classify the anemia and determine its cause.
