ABSTRACT

BACKGROUND AND AIMS: Parathyroid hormone (PTH) acts on bone as both anabolic and catabolic factor. It includes two fractions: 1-84 (cyclase activating PTH, CAP) which increases bone turnover and serum calcium, and 7-84 (cyclase inactivating PTH, CIP) acting the opposite way. The aim of this study was to establish whether bone mineral density (BMD) and turnover in patients' primary hyperparathyroidism (HPT) are dependent on CAP and CIP concentrations. PATIENTS/METHODS: Thirty-one patients with HPT and 29 appropriately matched controls were examined. Parameters of calcium-phosphate homeostasis and BMD were estimated. RESULTS: BMD of radius shaft was lower in patients with HPT as compared with controls, whereas BMD of spine and ultradistal radius were similar. Serum calcium, bone alkaline phosphatase, total PTH, 1-84 PTH, and 7-84 PTH were higher in HPT patients, whereas serum phosphate was lower and beta cross-laps similar. Both total PTH and CAP correlated significantly with BMD of radius shaft and serum calcium concentration, but not with other examined parameters. CONCLUSION: Total and 1-84 PTH are similarly associated with examined parameters in patients with HPT. Thus, determination of serum CAP concentration does not seem to have advantages over total PTH with regard to bone mineral density and bone turnover assessment in those patients.

ABSTRACT

The clinical course and diagnostic difficulties in a case of eosinophilic leukaemia are described. For a long time period the case showed clinical manifestations of a hypereosinophilia syndrome. Shortly before death clinical signs of leukaemia developed, and the diagnosis was confirmed on autopsy.
