Hyperparathyroidism, cirrhosis, and portacaval shunt. A new clinical syndrome.
This is a report of six patients with cirrhosis of the liver in whom primary hyperparathyroidism occurred due to a solitary parathyroid adenoma 3 months to 9 years after undergoing emergency portacaval shunt for hemorrhage from esophageal varices. The presenting symptoms in all six patients were weakness and bone pain. Three patients had a bone fracture after insignificant trauma, one and probably two passed kidney stones, and a duodenal ulcer developed in two. Bone x-ray films showed generalized osteoporosis in all patients. Renal function and arterial blood pH were within normal limits in every patient. The diagnosis of primary hyperparathyroidism in each patient was based on repeated demonstrations of hypercalcemia, hypophosphatemia, and markedly elevated serum immunoreactive parathyroid hormone concentrations. In all six patients, removal of the parathyroid adenoma resulted in disappearance of symptoms; normalization of serum calcium, phosphorus, and immunoreactive parathyroid hormone levels; and in four of the six, improvement in radiographic evidence of osteoporosis during follow-up of from 1 to 6 years. The association of cirrhosis, portacaval shunt, and primary hyperparathyroidism has not been documented previously. Our six patients with primary hyperparathyroidism constitute 3.4 percent of 174 survivors of emergency portacaval shunt in a series of 264 unselected, consecutive patients with cirrhosis and bleeding esophageal varices. Hepatic osteodystrophy is known to have occurred in only 11 of these 174 survivors. Primary hyperparathyroidism may be a more common cause of hepatic osteodystrophy than has been previously recognized, and should be considered in patients with cirrhosis in whom weakness, bone pain, and bone demineralization develop, particularly if they have a portacaval anastomosis.
