Study Notes
Understanding Anemia: Key Points
- Anemia is a presentation of an underlying condition, and symptoms depend on the etiology, acuity of onset, and comorbidities, particularly cardiovascular disease.
- Erythropoietin (EPO) is the major stimulator of red blood cell production, and levels of EPO are generally inversely proportional to the hemoglobin concentration.
- Normal hemoglobin ranges are 13.5-18.0 g/dL in men, 12.0-15.0 g/dL in women, 11.0-16.0 g/dL in children, and varied in pregnancy.
- The etiology of anemia depends on whether it is hypoproliferative or hemolytic, with various causes including alcohol, liver disease, myelodysplastic syndrome, and hemoglobinopathies.
- Anemia is extremely common, affecting up to one-third of the global population, with higher prevalence in women of reproductive age, pregnant women, and the elderly.
- The pathophysiology of anemia varies depending on the primary cause, such as acute hemorrhagic anemia resulting in proportionate reduction in plasma and red cells, leading to falsely normal hemoglobin and hematocrit.
- Increased RBC destruction can occur due to blood loss, including acute or chronic hemorrhage, heavy menstrual bleeding, and hemolytic anemia.
- Deficient/defective erythropoiesis can result in microcytic, normocytic, or macrocytic anemia, with various causes such as iron, vitamin B12, or folate deficiencies.
- A thorough history and physical examination are crucial for diagnosing anemia and determining the underlying cause.
- Anemia is common in elderly patients, often due to poor nutrition, renal failure, or chronic inflammation.
- New-onset anemia, especially in those over 55 years of age, should be investigated, particularly in men, and race is an important determinant, with higher prevalence in the African American population.
- At-risk groups for anemia include alcoholics, the homeless population, and those experiencing neglect or abuse, and new-onset anemia in men over 55 should be considered as potentially cancerous until proven otherwise.
