Surgical treatment of secondary hyperparathyroidism (HPT) in patients having renal replacement therapy (RRT) is a current problem. The aim of our study was to optimize the treatment of secondary HPT based on the comparative analysis of effectiveness of the surgeries with different extents. We conducted a retrospective analysis of the results of surgical treatment of uremic HPT in 34 patients. 36 surgeries were performed including 34primary (16subtotal parathyroidecomies (PTE), 13total parathyroidecomies (total PTEI), 5total parathyroidecomies with central neck dissection and resection of superior mediastinum and superior thymus horns (total PTEII)) and 2repeated surgeries (total PTEII and parathyroidadenomectomy). Gross examination of 134 surgical specimens revealed dyssynchronous pathological changes in parathyroid glands (PTG), normal PTG structure was found in 2cases. Recurrent HPT was found in 3 cases, persistent HPT – in 9cases, hypoparathyroidism – in 5cases after subtotal PTE and in 9 cases after total PTE with autotransplantation (p=0,267). Target values of parathyroid hormone were registered in 8patients, including 4 patients after subtotal PTE and 4 patients after total PTE (p>0,95). Morbidity was similar in all types of surgeries (p>0,5). Analysis of morbidity determined that simultaneous surgery of thyroid gland increased the risk of laryngeal paralysis (р=0,028). The decrease in occurrence of secondary HPT persistence (with the source accessible for removal through cervical approach) at total PTE based on the removal of parathyroid glands of all localizations accessible through cervical approach (including thyroid gland lobes with diagnosed ectopia, central cervical fat pad, superior mediastinum and superior thymus horns) was registered (NNT=4).

Parathyroidectomy is the leading treatment for drug-refractory secondary and tertiary hyperparathyroidism in patients with chronic kidney disease. Difficulties in performing this surgery are mainly associated with the anatomical features of the parathyroid glands, in particular with the variability of their number and topographic anatomy. Ectopic parathyroid glands are one of the most common causes of persistence or recurrence of secondary hyperparathyroidism after surgery. One of the common variants of ectopia is the localization of the parathyroid gland in the anterior-superior mediastinum. The article discusses the features of surgical treatment of secondary hyperparathyroidism in patients with end-stage chronic kidney disease with this ectopia. A new method of treating hyperparathyroidism in patients with an atypical location of the parathyroid gland in the anterior-superior mediastinum is presented. This method is characterized by low invasiveness of access, ease of implementation without using special equipment and instruments. The proposed method was used in the treatment of a patient with secondary hyperparathyroidism due to chronic renal failure as a result of chronic glomerulonephritis. The duration of hemodialysis at the time of the surgery was more than 17 years. In the presented clinical case, ectopia of one of the pathologically altered parathyroid glands in the anterior-superior mediastinum was found at the preoperative stage. As a method of surgical treatment, we carried out total parathyroidectomy with autotransplantation of a fragment of parathyroid tissue into the brachioradialis muscle. Thanks to this method, it was possible to remove the atypically located parathyroid gland from the cervicotomy access and to discharge the patient within the standard terms for a given volume of surgery.

The purpose of the study was to define indications for surgical treatment and its scope in patients with secondary hyperparathyroidism in the presence of end-stage chronic renalfailure. The authors examined 80 patients who had a history of long-term procedures of hemo- or peritoneal dialysis. The patients’ mean age was 47±3.2 years. Measurements of the levels of alkaline phosphatase, ionized and total calcium, phosphorus, parathyroid hormone, ultrasound of the parathyroid glands, densitometry and X-ray study were made in all the patients. All the patients received alfacalcidole therapy during different periods of time. Clinical, laboratory, and morphological correlations were made to establish indications for surgical treatment. The sensitivity ofpreoperative ultrasonography was 72.5% and that of intraoperative ultrasound study was as high as 98.4%. The sensitivity of intraoperative revision was 75%. Sixteen of the 20 patients operated on underwent total parathyroidectomy by autografting a fragment of one of the least glands into the muscle. Subtotal parathyroidectomy was made in 3 patients; 3 parathyroid glands were removed in 1. Emergency and planned studies were performed in all the patients. The duration of the patients operated on averaged 14 months. Three patients undergone total parathyroidectomy with autografiing developed signs of hyperparathyroidism following 6, 12, and 13 months, in this connection graft resection was made in these patients. In the follow-up periods of 3 to 6 months, the level of parathyroid hormone became normal after resurgery in 2 of these patients, hypoparathyroidism developed in one patient. Two months after surgery, recurrent secondary hyperthyroidism was detected in 2 of the 3 patients who had undergone subtotal parathyroidectomy (4 and 7 months after the occurrence of signs of transient hypoparathyroidism) and in 1 patient in whom 3 parathyroid glands had been removed. Four of the 20 patients operated on were observed to have hypoparathyroidism that was compensated by calcium preparations and active forms of vitamin D3. Thus, a good result was noted in 70% of the patients after surgical treatment.

Background. Sporadic multiple gland disease in primary hyperparathyroidism occurs in 7 to 33 % of cases. The absence of specific risk factors, low sensitivity of imaging methods, and low efficiency of bilateral neck exploration and intraoperative monitoring of parathyroid hormone indicate the complexity of the diagnosis and treatment of this disease’s form. Aim of the research. To analyze the results of surgical treatment of multiple lesions of the parathyroid gland in primary and secondary hyperparathyroidism. Methods. There was retrospective study, which included 100 observations of surgical treatment for primary and secondary hyperparathyroidism in the thoracic department of Irkutsk Regional Clinical Hospital from May 2018 to September 2019. The main point was to identify the frequency of surgical treatment outcomes in patients with multiple parathyroid lesions. As part of the study, potential predictors of multiple gland disease in primary hyperparathyroidism were analyzed. Results. Multiple gland disease in primary hyperparathyroidism occurs in 29 % of cases and causes persistence of the disease (p ≤ 0.01). Signs of multiple gland disease in primary hyperparathyroidism include the level of ionized calcium, parathyroid hormone (p ≤ 0.05), creatinine level and glomerular filtration rate (p ≤ 0.01). A negative result of intraoperative monitoring correlates with persistence of primary hyperparathyroidism in multiple lesions (χ2, p ≤ 0.05). Selective parathyroidectomy is associated with persistence of hyperparathyroidism in multiple lesions (χ2, p ≤ 0.05), while total parathyroidectomy is associated with remission of the disease (χ2, p ≤ 0.05). We did not find a statistically significant relationship between the results of surgical treatment for morphology of the parathyroid glands (χ2, p > 0.1). Conclusion. Multiple gland disease is the main cause of persistence of primary hyperparathyroidism. This form of the disease corresponds to lower levels of calcium, parathyroid hormone, and kidney function. Persistence factors have been established: removal of less than four parathyroid glands and a negative result of intraoperative monitoring of parathyroid hormone. Bilateral neck exploration does not reduce the incidence of disease persistence.

Background. The growing number of haemodialysis patients and the increasing their life expectancy within the past few years have resulted in a rise of long-term haemodialysis-associated complications. The aim of the paper is to present a case study of a successful surgical treatment of secondary hyperthyroidism and assess the causes of the disease. Materials and methods. A 63-year-old male patient had been on haemodialysis for 18 years; he had undergone parathyroidectomy for secondary hyperparathyroidism 10 years ago. The relapse of the disease was suspected when the patient developed the onset of pruritus and muscle pain. The following tests were performed: biochemical markers of plasma calcium and parathyroid hormone, thyroid ultrasound examination, parathyroid gland 99 mTc MIBI scintigraphy, single photon emission computed tomography of the neck and mediastinum. Results. Elevated calcium (2.73 mmol/l serum) and parathyroid hormone (1352 pg/ml blood plasma) levels were found. Ultrasound examination, 99 mTc MIBI scintigraphy and SPECT revealed parathyroid adenoma of the left inferior thyroid section. The patient underwent surgery in 2011. Remnants of the previously resected parathyroid gland were removed, and an accessory parathyroid gland was found within the thymus; this gland was removed, and partial autotransplantation was performed. The level of the parathyroid hormone decreased to 24 pg/ml during the day after surgery. The histological examination of the removed tissues was performed. Conclusions. Accessory parathyroid glands are usually found within the thymus; therefore, any type of surgical treatment of secondary hyperparathyroidism should include thymectomy.

Surgical Failure

Ectopic or supernumerary parathyroid glands (PTg) can be the reason of surgical failure in treat- ment of secondary hyperparathyroidism in patients, who underwent dialysis. The aim of this study is to estimate the number and localization of PTgs in patients with secondary hyperparathyroidism. We included 165 patients, who underwent total parathyroidectomy with heterotopic autotransplantation of parathyroid gland tissue or subtotal parathyroidectomy. All identified PTgs were separated in two groups: eutopic and ectopic. Preoperative localization was performed by multispiral computed tomog- raphy of neck and mediastinum, neck ultrasonography, two-isotope Tc99 MIBI of PTgs. In postopera- tive period, we estimated the level of parathyroid hormone in the serum and performed morphological verification. There were found 659 PTgs. 12 (7,2%) patients had 3 parathyroid glands, and 11 (6.7%)had 5 PTgs. 4 Ptgs were found in 142 (86,1%) patients. 520 (78,9%) PTgs were eutopic, 139 (21,1%) - ectopic. The most common ectopic place for upper PTgs were paraesophageal and retrotracheal spaces, carotid sheath. Ectopic lower PTgs were most commonly located in the horns of the thymus. All super- numerary PTg were ectopic and often located in area between lower pole of the thyroid lobe and the thymus.Conclusion. During the operation in case when ectopy is suspected, upper PTgs should be located in in paraesophageal and paratracheal areas or in carotid sheath, if it necessary. If lower PTgs is absence, surgery should be completed cervical thymectomy.

Calcium Sensing

Cinacalcet HCl, an allosteric modulator of the calcium-sensing receptor (CaR), has recently been approved for the treatment of secondary hyperparathyroidism in patients with chronic kidney disease on dialysis, due to its suppressive effect on parathyroid hormone (PTH) secretion. Although cinacalcet’s effects in patients with primary and secondary hyperparathyroidism have been reported, the crucial relationship between the effect of calcimimetics and CaR expression on the parathyroid glands requires better understanding. To investigate its suppressive effect on PTH secretion in primary hyperparathyroidism, in which hypercalcemia may already have stimulated considerable CaR activity, we investigated the effect of cinacalcet HCl on PTH-cyclin D1 transgenic mice (PC2 mice), a model of primary hyperparathyroidism with hypo-expression of CaR on their parathyroid glands. A single administration of 30 mg/kg body weight (BW) of cinacalcet HCl significantly suppressed serum calcium (Ca) levels 2 h after administration in 65- to 85-week-old PC2 mice with chronic biochemical hyperparathyroidism. The percentage reduction in serum PTH was significantly correlated with CaR hypo-expression in the parathyroid glands. In older PC2 mice (93–99 weeks old) with advanced hyperparathyroidism, serum Ca and PTH levels were not suppressed by 30 mg cinacalcet HCl/kg. However, serum Ca and PTH levels were significantly suppressed by 100 mg/kg of cinacalcet HCl, suggesting that higher doses of this compound could overcome severe hyperparathyroidism. To conclude, cinacalcet HCl demonstrated potency in a murine model of primary hyperparathyroidism in spite of any presumed endogenous CaR activation by hypercalcemia and hypo-expression of CaR in the parathyroid glands.

The main treatment method of primary and tertiary hyperparathyroidism is surgery. However, surgical interventions on the parathyroid glands can lead to formidable complications such as laryngeal paresis and hypocalcemia. With this background, a comprehensive study examined the effectiveness of modern methods of diagnosis and surgical treatment of hyperparathyroidism to increase the safety level in surgery of the thyroid gland. The results of a comprehensive examination and treatment of 53 patients with hyperparathyroidism who underwent surgery using three methods were analyzed: traditional (n = 18/34); minimally invasive endoscopically assisted (n = 32/60), and endoscopic (transoral) (n = 3/6). Intraoperative neuromonitoring was also performed in all surgical interventions. Parathyroidectomy was performed under parathyroid monitoring for intraoperative topical diagnosis of parathyroid tumors in nine patients. The use of minimally invasive endoscopically assisted access to the parathyroid glands, as an alternative to the traditional approach, indicated that the preoperative potential in the diagnosis of parathyroid disorders. Moreover, intraoperative neuromonitoring and parathyroid monitoring demonstrated efficiency based on the decline in the incidence of specific postoperative complications with a tolerable increase in operative time, maintenance of the average duration of stationary treatment after surgery, and increased safety level of surgical treatment of hyperparathyroidism.
