pubmed-article:10897661pubmed:abstractTextParathormone (PTH) exerts vasomodulatory effect. In patients with severe hyperparathyroidism (HPTx) post transplant (Tx) PTH level decreases slowly and this could be a reason of delayed graft function. Case 1: 19 years old female; 2 years of CAPD-renal Tx lost after 8 years--6 years on hemodialysis (HD), clinical symptoms of severe HPTx (iPTH > 1300 pg/ml). Elective parathyroidectomy was cancelled as patient received the second graft. Then she was oliguric and required regular HD from the 4th day after Tx. We observed increasing resistance index (RI) and finally no diastolic blood flow in graft USG-Doppler scan. Ten days after Tx, the patient was revised surgically and renal biopsy was performed. No pathology but slight ATN was found. At the same time iPTH level was 1225 pg/ml. Plasmapheresis (PF) was introduced, decreasing iPTH level to 850 pg/ml, 995 pg/ml, and 345 pg/ml respectively. After the second PF urine output increased (to 600 ml). Serum creatinine level decreased from 7.3 to 1.3 mg/dL within the next 10 days. Actually (5 months post Tx) graft function remains stable (creatinine 1.2 mg/dl). The level of iPTH at the second month after Tx was 756 pg/ml, at 4th month--439 pg/ml. Case 2: M.P. 20 years old female initially on HD, then Tx, lost after 5 months because of FSGS recurrence--again HD therapy. She developed severe secondary HPTx (iPTH level > 1300 pg/ml). Planned parathyroidectomy was cancelled as she received a second transplant. After Tx she was anuric for 5 weeks and was treated with HD. She had high RI index in repeated USG-Doppler scans, blood flow in renal cortex was deceleration. Repeated renal biopsy showed no pathology and PF therapy was introduced. After the first PF the patient started to urinate, after the 5th--the urine output was 1000 ml. Overall 10 PFs were done. Now, 13 months after Tx, graft function is satisfactory (creatinine level 2.1 mg/dL). The level of iPTH in 4th month after Tx was 772 pg/ml, in 10th month--631 pg/ml. We suggest that disturbances in graft blood flow were influenced by high level of iPTH, decreased successfuly by PF therapy.lld:pubmed
