To demonstrate the possibility of successful treatment of a severe postsurgical hypoparathyroidism by the cultured parathyrocyte allotransplantation to a kidney transplant recipient. Methods. A 37-year-old female with the kidney transplant and a severe postsurgical hypoparathyroidism on the background of intensive replacement therapy was a recipient of parathyroid allograft. The indications for parathyroid autotransplantation include symptoms of tetany, high convulsive readiness (Chvostek’s and Trousseau’s signs), extremely low rates of total/ionized calcium (1,71/0,98 mmol/L) and parathyroid hormone (1,7 pg/ml) in the peripheral blood. culture (21×106) of parathyroid cells obtained from a living unrelated donor (62-year-old female) with the secondary hyperparathyroidism was implanted into the recipients’ left brachioradialis muscle. Site selection for parathyroid allograft was conditioned by the absence of arteriovenous fistula on the side of the transplantation. Immunosuppressive therapy consisted of 150 mg/day of cyclosporine, 720 mg/day of mycophenolic acid, 6 mg/day of methylprednisolone. Results. No postoperative complications of the intervention, local and general side effects on the parathyroid cell allograft were observed. Clinical and laboratory improvement of hypoparathyroidism occurred 1 month after the transplantation: parathyroid hormone concentration increased up to 14,7 pg/ml and reached a maximum value (61,7 pg/mL) after 3,5 months. No convulsions were observed over a 6-month follow-up, Chvostek’s and Trousseau’s signs were stopped, the amount of oral substitution therapy significantly reduced, and there was no more need for parenteral administration of calcium salt solutions. Six months after transplantation a patient led a very active life and took per os 0,5 g/day of calcium. Conclusion. Combined allotransplantation of cadaveric kidneys and cultured parathyroid cells obtained from the hyperplastic parathyroid tissue of a living unrelated donor is considered to be an effective treatment of permanent severe hypoparathyroidism in patients who need the organ transplantation with subsequent immunosuppressive therapy.

Introduction

Secondary or tertiary hyperparathyroidism is the most frequent cause of hypercalcemia in patients with the terminal chronic kidney disease (CKD). Subtotal parathyroidectomy is a safe and efficacious treatment for hyperparathyroidism after which the risk of a severe hypercalcemia development occurs in less than 1-2% of the operated patients. [1]. The severity of the symptoms specific to hypocalcemia can vary widely and sometimes even be life-threatening in case of a generalized convulsive seizure, refractory heart failure, laryngospasm. Being an extremely severe complication, hypocalcemia requires lifelong calcium (high doses) and vitamin D3 replacement therapy (including intravenous injections) and in the distant future it may cause the development of cataracts, basal ganglia calcification, extrapyramidal signs, nephrocalcinosis and renal failure. Besides, the need of daily large number drug intake and the requirement of frequent parenteral administration of calcium salt solutions negatively affect the quality of patients' life.

Until now, the physiologic and simultaneously safe method of successful parathyroid allotransplantation without recipient's immunosuppression has not been developed yet.It should be noted that in some countries parathyroid hormone (PTH), commonly used for other indications, is now available for the treatment of patients with HPT. In the available literature of the recent century, it was presented in the literature in the form of few reports of cases from practice (with/without reciepient's immunosuppression), as one of the treatment methods of permanent HPT (Table 1) [2-21]. However, as demonstrated by S. Wells et al. [22], it was enough to perform autotransplantation of several fragments of the hypertrophied parathyroid gland (PTG) without its direct revascularization for the successful prevention of permanent HPT after total parathyroidectomy. In 1974, S. Wells et al. used a parental allograft (2 parathyroid glands), which were obtained from father and transplanted to son with kidney transplant. [7].

Objective. To demonstrate the possibility of

successful treatment of a severe postsurgical hypoparathyroidism by the cultured parathyroid cells allotransplantation to a kidney transplant recipient.

Clinical observation

The recipient of a parathyroid cell allograft was a woman (aged 37 years), since childhood suffering from a chronic glomerulonephritis led to nephrosclerosis and as a result being on the scheduled hemodialysis therapy for the recent 18 years. Against the background of the terminal cronic kidney disease stage and 11 years after starting dialysis the secondary hyperparathyroidism has developed and it may serve as an indicator of the total para-thyroidectomy.After 6 months the logical outcome of a radical surgery on parathyroid gland (PTG) was a severe postoperative hypocalcemia that developed in permanent and required orally per day calcium supplementation (up to 4 g), cholecalciferol (up to 1 800 IU), calcitriol (1,25 mcg), and frequent (1-2 times per week) intravenous injections of 2-4 g of calcium gluconate for the seizures relief.

In August 2015, the heterotopic transplantation of the cadaveric kidney was performed and the immunosuppressive therapy was prescribed (cyclo-sporine 150 mg/day, mycophenolic acid 720 mg/ day, methylprednisolone 6 mg/day). 5 months after transplantation a regular laboratory and instrumental examination showed relatively satisfactory kidney transplant function. Serum urea indices ranged from 9,8 to 11,8 mmol/l, creatinine - from 141 to 184,8 micromol/l; glomerular filtration rate — from 29,4 to 30,8 mL/minute. Cyclosporine blood concentration ranged within 71,2 ng/ml. At the same time despite the maximum possible (for calcitriol) HPT replacement therapy application no current method is able to reverse or delay the disease's progress. Against the background of very low rates of total / ionized calcium (1,71/0,98 mmol/l; normal range 2,15-2,55/1,12-1,32 mmol/l) and parathormone (17 pg/mL; normal range of15-65 pg/ml) in the peripheral blood, the symptoms of tetany and high convulsive readiness remained

(Chvostek's 4+ and Trousseau's signs). In addition, the patient complained of paresthesia, muscle weakness and fasciculations, fatigue during even little physical or mental stress. In December 2015, taking into account an extremely severe course of the postoperative HPT, refractory hypocalcaemia, the patient's young age and persistent immunosuppression, it was decided to perform allotransplantation of the cultured parathyroid cells extracted from the parathyroid tissue of a living-unrelated donor (a woman of 62 years old) with the secondary hyperparathyroidism. There was

no donor-recipient compatibility regarding ABO-phenotype and Rh-factors — A (II) Rh + vs O (I) R-. HLA-typing was not performed.

Under the local anesthesia the skin and subcutaneous tissue were dissected (over 2 cm), the fascia of the left humeroradial muscle was exposed, 2 l of the cell suspension (21*106 of parathyrocytes) was injected via 18 G needle into muscle transfascially (figure). Site selection for parathyroid allograft was conditioned by the absence of arteriovenous fistula on the side of the transplantation.

Within the incisional period no complications, local and general side effects to the parathyroid cell allograft were registered. 1 month after the parathyroid cells transplantation, the clinical-laboratory compensation of hypoparathyroidism had occured (Table. 2). Cyclosporin concentration was 137 ng/mL , urea — 15,8 mmol/L, creatinine — 147,2 mmol/l, glomerular filtration rate — 38,7 mL / minute in blood. Within a 6-month observation period no convulsive syndrome manifested, Chvostek's and Trousseau's signs were stopped, the volume of oral substitution therapy reduced significantly (from 13-15 to 1-2 tablets), there was no need for parenteral administration of calcium salt solutions that positively affected on increased physical activity and life quality of the recipient. 6 months after the transplantation the patient led a normal life and took per os Ca 0,5 g/day, which was a usual medicinal supplement in almost all patients with a functioning kidney transplant.

Discussion

The most common HPT cause is a surgical

intervention in the neck region (mainly in case of thyroid gland pathology and PTG) or "non-surgical" PTG destruction after radiotherapy [23]. Congenital HPT occurs much less frequently, both alone and in combination with other metabolic disorders and anatomic abnormalities. However, regardless of etiology, clinical symptoms of hypocalcemia are similar, the severity of which due to its life-threatening potential varies from perioral numbness, paresthe-sia, muscle spasms to laryngospasm and tetany. A lifelong supplementation (calcium and vitamin D) will be required to patients, but often such therapy may not be manifested by a stable normalization of calcium homeostasis, because of their tendency to develop late complications. Nowadays, HPT replacement therapy with synthetic PTH has been developed — two injectable forms of parathyroid hormone, Natpara (I-84) and Forteo or teriparatide (I-34) are available for therapeutic use in the USA.

In January 2015, FDA (Food and Drug Administration) has approved the therapeutic use of PTH (I-84) as a daily subcutaneous injection. However, until now there is no experience of PTH (I-84) use in patients with a severe postoperative HPT and calcium-sensing receptor mutations. In addition, long-term use of Natpara is associated with a potential osteosarcoma risk. On the other hand, in accordance with FDA requirements, PTH (I-34) is used as therapy for osteoporosis and, having a short-term effects, requires multiple daily injections. It should be noted that both therapeutic options are still expensive (average wholesale price: Natpara $ 4750 / month, of Forteo $ 2111 / month), and the clinical effect depends on the patient's adherence to treatment. The use of portable PTH batchers in the form of so-called "portable pump" permitted to achieve more stable values of serum calcium [24].

Theoretically parathyroid allotranspantation could be an ideal therapeutic technique to restore a normal calcium homeostasis. Reports of a number of authors demonstrate good results of transplantation of a normal or hyperplastic PTG from living or cadaveric donors [2-22]. However, the need for lifelong immunosuppression significantly limits the clinical application of a similar approach.

In 1911, W. Brown [2] reported firstly about the transplantation of allogenic PTG to a young patient with a severe HPT, refractory to intravenous calcium asministration, occurred after the total thyroidectomy. Xenotransplantation of several PTG and thyroid glands has not brought any positive result and, ultimately, the patient was transplanted an allogenic PTG of a deceased donor. Before the implantation the parathyroid tissue was fragmented and was stored in saline at temperature (32° F). At least within 4 months after surgery no HPT symptoms occurred.A little bit latter the attempts to treat the primary or congenital HPT by allotransplantation of small parathyroid fragments which required no immunosuppression has been made [3, 25]. Experimental studies were associated foremost with the study of the effectiveness of direct PTG revascularization [26]. The first clinical transplantation of the fetal thyroid-parathyroid complex by using a single "pedicle" anastomosis with the recipient common femoral artery was performed in 1954 [4]. Technical difficulties of the operation related to a small caliber of the anastomosed vessels were justified by less immunogenicity of a fetal transplant. The symptoms of tetany were stopped immediately following surgery and had not recurred within 12 months. Later such interventions had been used successfully in 12 of 14 patients within a 6-year follow-up [5, 9].

In 1973, C. Groth el al. [6] firstly described a case of a stable functioning of parathyroid al-lograft wthin 21 months in the patient, receiving immunosuppression on the regular basis following kidney transplantation. According to the authors, immunosuppressed patients with HPT after the organ transplantation appeared to be a "promising" parathyroid allograft recipients with a high probability of its long-term functioning. According to N. Torregrosa et al. [14], the justified and legitimate source of PTG could be living unrelated donors, operated on for the parathyroid hyperplasia. There were reports in the recent literature concerning successful use of 1-2 PTG of healthy closely related donors (father, mother, sister), some of whom occasionally were kidney donors [7, 19, 20]. PTG retransplantation with a positive clinical effect was performed by B. Duarte et al. in the case of early dysfunction or failure of a "primary" parathyroid transplant [8].

Parathyroid tissue also expresses antigens of I and II classes of the major histocompatibility complex, which are capable inducing an immune response. To reduce the immunogenicity of donor material both in a clinic and in experiment, among the other approaches, the cultured parathyrocytes [3, 12, 21], HLA- "purified" microspheres [12], cryopreserved parathyroid tissue [13, 17, 21]; the

technique of micro- and macroencapsulation [13, 16, 21] and elimination leucocytes-"passengers" in the culture medium [27] were also applied for the transplantation (Table 1).

I. Nawrot et al. [28] presented the treatment results of 85 patients with postsurgical hypopara-thyroidism, who underwent intramuscular allotransplantation of 20-30x106 cultured and cryopreserved parathyroid cells obtained from the donors with the secondary and tertiary hyperparathyroidism (retransplantation of parathyroid cells was required in 25 cases). As the experience of Polish colleagues showed [28], cryopreservation of parathyroid cells permitted to improve the results of clinical allotransplantation in the absence of immunosuppression: the average duration of the allograft functioning was 6.4 months. A. Saxe et al. found out that the freezing of parathyroid tissue reduced HLA expression on surface of parathyroid cells and their immunogenicity [29].

C. Hasse et al. [13] used firstly alginate micro-encapsulation technology in allotransplantation of parathyroid cells: 20 microspheres with parathyroid tissue were implanted into the forearm muscles to each of two patients with postsurgical hypopara-thyroidism; functioning period of allograft was 3 months. According to the authors' data, the alginate microsphere provides a reliable barrier for molecules larger than 150 kDa, prevents the penetration of immunocompetent cells, immunoglobulins, complement components and, at the same time, provides the nutritional support for the transplant and free diffusion of parathyroid hormone in the blood. Immune mechanisms of rejection are based on the activation of T lymphocyte subpopulations, including CD8 +, whereas, a mechanical cell isolation in the microsphere prevents the interaction between the encapsulated tissue and the recipient's immune system [12].

Another immunoprotective approach is mac-roencapsulation of parathyroid cells based on the same principles [21]. The application of tissue and cell parathyroid encapsulation may be justified in patients with a severe hypocalcaemia who are not organ recipients, and, accordingly, require no "aggressive" immunosuppression.

The first successful multiorgan transplantation — kidney-pancreas and parathyroid tissue was performed in the patient with an autoimmune poly-glandular syndrome and medullary cystic disease [30]. Within the insicional period a four-component immunosuppression was applied — anti-thymocyte globulin, azathioprine, cyclosporine, prednisone; and the parathyroid allograft functioning made up 2 years. N. Torregrosa et al. [14] reported about the case of a successful parathyroid allotransplantation in a 38-year-old patient with the anamnesis of

kidney transplantion and total parathyroidectomy due to CKD and secondary hyperparathyroidism. Against the background of immunosuppressive therapy with corticosteroids, azathioprine and cy-closporine, the terms of therapeutic effect made up 2 years, and the peak concentration of PTH — 34 pg/mL was observed one year after the surgery. S. Flechner et al. [17] described another case of successful allotransplantation of cryopreserved parathyroid tissue into the humeroradial muscle of a 36-year-old man with the transplanted kidney. Just before the kidney transplantation due to the tertiary hyperparathyroidism the patient underwent subtotal, and then total parathyroidectomy with PTG autotransplantation into the deltoid muscle, which proved to be ineffective. In connection with the developed postoperative severe HPT (PTH 5 pg/mL) the patient was subjected to the re-allo-transplantation of parathyroid tissue obtained from one and the same donor (a three-month interval). Duration of the allograft functioning was 11 months (PTH 15 pg/mL) against the background of ongoing immunosuppression (tacrolimus, mycophenolate mofetil, steroids). Immunosuppression regime after kidney transplantation was sufficient to restore the PTH secretion, but information about the most preferred immunosuppressive drugs used in parathyroid allotransplantation is absent. According to S. Flechner et al. [17], the basic requirements to the source of the donor parathyroid tissue are the absence of antibodies to human immunodeficiency virus (HIV), hepatitis B and C, HLA phenotypes to which the recipient has already been sensitized; ABO compatibility, cryopreservation duration less than 1 year. However, in practice, it is rather difficult to apply a similar screening of the tissue typing due to the donor pool was limited by 4 donors.

Based on the available literature reports and the author's experience [21] in the present observation two complementary approaches were firstly used—immune alteration precultivation) of the parathyroid tissue of a living unrelated donor and recipient immunosuppressive therapy with the kidney transplant. Probably, the combined use of these methods of "avoidance" from the immune response has led to complete HPT compensation and has significantly extended the functional activity of parathyroid allograft.

Conclusion

Permanent hypoparathyroidism occurs in 1-2% of patients who underwent the surgeries on the thyroid gland or other organs of the neck, and it is characterized by hypocalcemia, low serum PTH levels and the presence of clinical symptoms within 6 months or more. Traditional HPT treat-

ment involves a lifelong intake of "drug- intermediates" — calcium and vitamin D, but not of PTH and it explains insufficient effectiveness of drug therapy. In this connection, the search of new effective methods of HPT treatment is being carried out, including the use of transplant technologies. Parathyroid allotransplantation is considered to be a potentially promising treatment of HPT, however, the reaction of rejection still remains a major problem. Prolonged immunosuppression permits to extend allograft functional activity, but is able to cause a number of side effects and complications, and its application is scarcely justified in the case of transplantation therapy of "isolated" HPT. At the same time, a combined allotransplantation of the cadaveric kidney and cultured parathyroid cells isolated from the hyperplastic parathyroid tissue of a living unrelated donor is thought to be an effective treatment of severe permanent HPT in patients who need the organ transplantation with subsequent immunosuppressive therapy.

The work was performed under the state innovation project "To develop and implement a method of surgical treatment of hypoparathyroidism" (State registration 20132515).
