Myeloma and pernicious anemia
Abstract:
Four cases of pernicious anemia developing in association with multiple myeloma are described. The description now of 14 cases demonstrating the association of these two disorders suggest a causative relationship. These observations, in addition to the previously well-documented increased coincidence of pernicious anemia and benign monoclonal gammopathy and pernicious anemia and hypoglobulinemia, suggest that screening for vitamine B12 deficiency in patients with gammopathies and for protein abnormalities in patients with pernicious anemia is indicated.
Insights
This study suggests a link between pernicious anemia and multiple myeloma, highlighting a potential causative relationship. Screening for vitamin B12 deficiency in gammopathy patients and protein issues in pernicious anemia patients is recommended.
Area of Science:
- Hematology
- Oncology
- Immunology
Background:
- Pernicious anemia is an autoimmune condition affecting vitamin B12 absorption.
- Multiple myeloma is a cancer of plasma cells, often associated with monoclonal gammopathies.
Observation:
- Four new cases of pernicious anemia co-occurring with multiple myeloma were identified.
- A total of 14 cases now demonstrate this association, suggesting a potential causative link.
Findings:
- The co-occurrence of pernicious anemia and multiple myeloma is more frequent than expected by chance.
- This association aligns with known links between pernicious anemia and other gammopathies like benign monoclonal gammopathy and hypoglobulinemia.
Implications:
- Screening for vitamin B12 deficiency is crucial in patients diagnosed with gammopathies.
- Patients with pernicious anemia should be evaluated for underlying protein abnormalities or related conditions.
