[levels of erythropoietin in serum of patients with primary hyperparathyroidism].
The present study aimed assess the relationship between erythropoietin (EPO) and parathormone (PTH) secretion in patients with primary hyperparathyroidism (PHP). Seventeen patients with PHP and 24 patients with uncomplicated cholelithiasis were examined before and during 14 days after surgical treatment. In PHP patients plasma EPO levels were significantly higher than in patients with cholelithiasis (31.5 + 4.3 vs 14.1 + 0.9 mU/ml, p < 0.01). After cholecystectomy transient increase of plasma EPO level was noticed postoperatively during the first 6 days. Such an increase of plasma EPO was absent in PHP patients after removal of the cause of primary hyperparathyroidism. Only in PHP patients a significant negative correlation was found preoperatively between plasma EPO level and Hct value or creatinine clearance respectively.


CONCLUSIONS
1. Patients with PHP are characterized by significantly elevated plasma EPO levels which are related to the degree of anaemia and decrease of GFR. 2. In patients with PHP presence of significant relationship between EPO and PTH secretion could not be proven.
