Calcitonin levels in chronic renal disease
Nephron
|January 1, 1977
Summary
Patients with chronic renal failure exhibit high serum calcitonin levels, linked to phosphate-calcium ratios and serum calcium levels. Successful kidney transplantation typically normalizes these calcitonin levels.
Area of Science:
- Nephrology
- Endocrinology
- Biochemistry
Background:
- Chronic renal failure (CRF) is associated with significant metabolic disturbances.
- Uremia affects calcium and phosphate homeostasis, potentially impacting bone metabolism and endocrine function.
- Elevated parathyroid hormone and altered vitamin D metabolism are common in CRF.
Purpose of the Study:
- To investigate serum calcitonin levels in patients with chronic renal failure.
- To explore the relationship between serum calcitonin, calcium, phosphate, and gastrin levels in CRF patients.
- To assess the effect of kidney transplantation on serum calcitonin levels.
Main Methods:
- Serum calcitonin, calcium, phosphate, and gastrin levels were measured in patients with CRF.
- Patients were stratified based on dialysis status.
- Serum calcitonin levels were re-evaluated after successful kidney transplantation.
Main Results:
- Patients with CRF demonstrated elevated serum calcitonin levels.
- Serum calcitonin showed a direct correlation with the phosphate to total calcium ratio.
- Calcitonin levels correlated inversely with serum calcium in dialysis patients and directly in non-dialysis patients. Elevated serum gastrin was observed in all patients.
- Successful kidney transplantation led to a decrease in high serum calcitonin levels.
Conclusions:
- Hypercalcitonemia is a feature of chronic renal failure.
- The complex interplay between calcitonin, calcium, phosphate, and gastrin in uremia requires further investigation.
- Kidney transplantation appears to resolve the hypercalcitonemia associated with CRF, suggesting a role for kidney function in calcitonin regulation.
