Targeted surgical parathyroidectomy in end ‐stage renal disease patients and long‐term metabolic control: A single‐center experience in the current era

Abstract Background: The long‐term results of surgical parathyroidectomy (PTX) in end‐stage renal disease (ESRD) patients are less well known in the modern era of newer activated vitamin‐D analogs, calcimimetics and intraoperative monitoring of parathyroid hormone (PTH).Methods: We performed a retrospective chart review of all ESRD patients undergoing PTX at the University of Mississippi Medical Center between January 2005 and August 2011, with follow‐up data as available up to 4 years. All PTXs were performed with intraoperative second‐generation PTH monitoring and targeted gland size reduction.Results: The cohort (N = 37) was relatively young with a mean (±SD) age of 48.4 ± 13.9. 94.6% of the subjects were African American and 59.5% female. Preoperatively, 45.9% received cinacalcet (CNC) at a mean dose of 63.5 ± 20.9 mg. The size of the largest removed glands measured 1.7 ± 0.8 cm and almost all (94.6%) glands had hyperplasia on histology. The mean length of inpatient stay was 5.5 ± 2.4 days. Preoperative calcium/phosphorus measured 9.6 ± 1.2/6.6 ± 1.7 mg/dL with PTH concentrations of 1589 ± 827 pg/mL. Postoperative PTH values measured 145.4 ± 119.2 pg/mL. Preoperative PTH strongly correlated (P

AbstractCalciphylaxis is a rare and severe disease that manifests with painful skin ulceration and necrosis. Herein, we report five patients of hemodialysis patients with skin biopsy-proven calciphylaxis at a single facility. One patient had undergone parathyroidectomy (PTx) due to severe secondary hyperparathyroidism, four had been treated with vitamin D receptor activators, and two were on warfarin therapy. All patients had hyperphosphatemia, and one had hypercalcemia. The intact parathyroid hormone level at diagnosis was 2  pg/ml in the patient after PTx, while three patients were within the target range. The avera...

ConclusionsLong hemodialysis periods and elevated PTH levels were the probable factors for the development of facial deformities in this group of patients. The main complications associated to the surgical management of facial deformities in ROD patients are directly related to end-stage renal disease, with increased risks for hemorrhage and systemic drug accumulation.

We present our initial experience with modified transoral endoscopic parathyroidectomy vestibular approach (m-TOEPVA) procedure for SHPT using total parathyroidectomy with autotransplantation. Materials and Methods: We retrospectively reviewed 10 patients with SHPT who underwent the m-TOEPVA procedure from December 2017 to April 2018 at our center. Results: There were a total of 6 male individuals and 4 female individuals with a median age of 58.5 years. Among whom, 5 were on hemodialysis and 5 on peritoneal dialysis. The median length of hospital stay and operative time was 5 (4, 5) days, and 321.5 (302.75, 362.25) ...

This study was performed with institutional review board approval. Written consent was obtained from each patient. Forty-eight patients (mean age ± SD 54.50 ± 13.14 years; range 33-77 years) undergoing maintenance hemodialysis who underwent PTX and 56 patients (mean age 55.28 ± 12.32 years; range 35-76 years) who did not undergo PTX received prospective follow-up for 2 years. CACS was quantitatively performed using the Agatston method after CT scan. The differences between baseline and end-of-study PTX parameters were analyzed with the paired Student t test. RESULTS: For patients who underwen...

Hyperkalaemia occurs frequently in many maintenance haemodialysis (MHD) patients after parathyroidectomy (PTX) with secondary hyperparathyroidism (SHPT). However, the clinical risk factors that predict postope...

The normal distribution of parathyroid glands is well documented. However, this study aims to evaluate the efficacy of total parathyroidectomy (TPTx) and bilateral cervical thymectomy (BCTx) for the treatment of secondary hyperparathyroidism (SHPT) through identifying the location of parathyroid glands with attention to the pattern and frequency of orthotopic and ectopic glands. Between 2013 and 2018, sixty chronic hemodialysis patients with medically refractory SHPT underwent TPTx &BCTx. The adequacy of the operation was defined by the pathological confirmation of at least 4 parathyroid glands, accompanied by an inta...

Rationale: Secondary hyperparathyroidism (SHPT) is often complicated with chronic renal failure. Though the total parathyroidectomy (TPTX) with forearm autotransplantation (FAT) has been commonly used to treatment refractory renal SHPT, the recurrence of SHPT is not infrequent, resulting from hyperplastic autograft, remnant parathyroid tissues, and supernumerary parathyroid gland (SPG). Patient concerns: A 67-year-old man undergoing TPTX+FAT 4 years previously for renal SHPT, who received regular hemodialysis with active vitamin D supplements of Rocaltrol treatment postoperatively, was admitted to our hospital with pr...

CONCLUSIONS: The effectiveness of cinacalcet were still obviously demonstrated even in chronic HD patients with severe SHPT. In addition, the improvements of bone markers and FGF-23, and stabilization of vascular calcification were observed. Therefore, cinacalcet can provide salutary effects on CKD-MBD in severe SHPT and might be an initially effective PTH-lowering therapy prior to surgical parathyroidectomy as well as an alternative treatment in the patients unsuitable for surgery.

Conclusion: In the present patients, long-term treatment with cinacalcet progressively decreased the total volume of parathyroid glands, as well as levels of intact PTH and phosphate in serum in a time-dependent manner. On the contrary, cinacalcet administration did not cause secondary failure or over-suppress the transition of parathyroid gland activity to hypoparathyroid status. These results suggest that cinacalcet treatment may postpone the need for parathyroidectomy and/or reduce its use even after long-term administration for up to 8 years.Nephron

AbstractPurposeIt is unclear whether clinical courses of hungry bone syndrome (HBS) after parathyroidectomy (PTX) in peritoneal dialysis (PD) and hemodialysis (HD) patients are different. The present study aimed to investigate the possible differences of postoperative hypocalcemia and hyperkalemia between PD and HD patients.MethodsWe performed retrospectively 29 PD patients as the PD group and 169 HD patients as the HD group undergoing successful total PTX with autotransplantation. Calcium supplement after surgery was recorded. Higher levels of serum potassium during and immediately after surgery were recorded as K+d0. K+d...
