Possible persistent endocrine function of a rejected renal allograft.
Clinical Nephrology
|December 1, 1977
Summary
A patient with hypertension and mild anemia despite kidney removal showed high levels of renin and erythropoietin. This suggests rejected kidney transplants, even calcified ones, may retain endocrine function without excretory ability.
Area of Science:
- Nephrology
- Endocrinology
- Transplantation
Background:
- A patient undergoing intermittent hemodialysis post-bilateral nephrectomy presented with hypertension and unexpectedly mild anemia.
- The patient had a history of a renal allograft implanted 8 years prior, which was rejected 4 years later but remained in situ.
Observation:
- Despite being anuric, the patient exhibited high plasma renin activity.
- Plasma erythropoietin activity was detected within the measurable range.
Findings:
- The observed hormonal activities were linked to a completely calcified renal allograft.
- These findings suggest the calcified allograft maintained endocrine function despite the absence of excretory function.
Implications:
- Chronically rejected renal allografts may retain endocrine capabilities even when non-functional and calcified.
- This highlights the potential for residual hormonal activity in non-viable allografts, relevant for understanding kidney transplant outcomes and endocrine regulation.
