Calcium pyrophosphate crystal deposition disease and hyperparathyroidism: a controlled, prospective study.
A prospective, controlled study of patients with primary hyperparathyroidism has been carried out to establish the relation of this endocrinopathy to calcium pyrophosphate dihydrate crystal deposition disease. Eight of 26 patients with documented hyperparathyroidism were found to have chondrocalcinosis compared to four of 104 individuals in the control group (p less than 0.01). Two of these eight patients had confirmed pseudogout attacks shortly after parathyroidectomy. Four other patients, including two without chondrocalcinosis, gave a history of typical pseudogout. Patients with hyperparathyroidism and chondrocalcinosis were significantly older than those without the articular lesion (p = 0.006). We could not delineate specific metabolic abnormalities of hyperparathyroidism which contributed to the development of chondrocalcinosis.
