Hypocalcaemic primary hyperparathyroidism
British Medical Journal
|January 24, 1970
Summary
This study details a patient initially presenting with hypocalcaemia and symptoms of primary hyperparathyroidism, later diagnosed with vitamin D deficiency and parathyroid adenoma. Treatment and surgery resolved the condition, suggesting primary hyperparathyroidism in similar cases.
Area of Science:
- Endocrinology
- Gastroenterology
- Bone Metabolism
Background:
- Primary hyperparathyroidism can present with complex symptoms, including hypocalcaemia.
- Osteomalacia and osteitis fibrosa can occur secondary to conditions like postgastrectomy steatorrhoea.
- The interplay between vitamin D deficiency, malabsorption, and parathyroid function requires careful evaluation.
Purpose of the Study:
- To investigate a case of apparent secondary hyperparathyroidism that resolved after vitamin D treatment and parathyroid adenoma removal.
- To differentiate between primary and tertiary hyperparathyroidism in patients with steatorrhoea and osteomalacia.
Main Methods:
- Clinical case presentation and biochemical analysis.
- Bone histology (osteomalacia and osteitis fibrosa).
- Surgical intervention (parathyroid adenoma removal) and follow-up.
Main Results:
- Initial presentation with hypocalcaemia, osteomalacia, and osteitis fibrosa.
- Development of hypercalcaemia upon vitamin D treatment, indicating unmasked primary hyperparathyroidism.
- Successful treatment following parathyroid adenoma resection.
Conclusions:
- Initial hypocalcaemia was attributed to vitamin D deficiency, masking primary hyperparathyroidism.
- Review of literature suggests most similar cases represent primary, not tertiary, hyperparathyroidism.
