Anemia linked to primary hyperparathyroidism is uncommon and resolves post-parathyroidectomy. Ferrokinetic studies suggest anemia of chronic disease, with other causes like GI bleeding or folate deficiency also identified.

Area of Science:

Endocrinology
Hematology
Internal Medicine

Background:

Primary hyperparathyroidism (PHPT) is a condition where the parathyroid glands produce too much parathyroid hormone.
The association between PHPT and anemia is not well-established, and the underlying mechanisms remain unclear.

Observation:

Two patients with PHPT presented with moderate normochromic, normocytic, reticulocytopenic anemia.
Ferrokinetic studies in these patients indicated patterns consistent with anemia of chronic disease.
One patient exhibited low serum iron and reduced normoblastic iron incorporation.

Findings:

Anemia in both index patients resolved completely following parathyroidectomy.
Review of 100 non-uremic PHPT patients identified three additional anemic cases.

Anemia causes in these three were upper gastrointestinal bleeding (two cases) and folate deficiency due to alcoholism (one case).

Implications:

Parathyroidectomy may effectively treat anemia in select PHPT patients.
Anemia of chronic disease is a potential mechanism for anemia in PHPT.
Other treatable conditions, such as gastrointestinal bleeding and nutritional deficiencies, should be investigated in anemic PHPT patients.
