Abstract

HLAи ABO-типирования пар донор-реципиент и потребности в иммуносупрессии.Objectives. To evaluate the effectiveness of macroencapsulated parathyroid cells allotransplantation into the arterial bed of patients with postoperative hypoparathyroidism and without immunosupression application. Methods. From December 2010 to November 2011 7 patients underwent to 7 allotransplantations of cultured macroencapsulated parathyroid cells it was indicated by the iatrogenic hypoparathyroidism after the thyroid surgery in all cases. An average recipient age was 52 [39-59] years. Donors were selected from patients undergoing parathyroidectomy for primary (adenoma) and secondary (due to chronic renal failure) hyperparathyroidism. Results. The cultivated cells with high concentration of parathormone in the cultured liquid (2927,5 [1400,54847] pg/ml) and the degree of viability (99%) were selected for the transplantation. The median cellular allograft survival was 3 [1-9] months. In 4 patients (57,1%) the allografts retained their endocrine function for more than 2 months. None of the patients showed clinical symptoms of hyperparathyroidism in the posttransplantation followup period. Conclusions. In some patients with hypoparathyroidism developed after the thyroid surgery, parathyroid cell allotransplantation is considered to be an effective therapeutic alternative vs the standard methods. Donors’ and recipients’ age, the duration of hypoparathyroidism didn’t influence significantly on the terms of the graft functioning. The problems concerning porosity, biocompatibility, long-term stability of the microporous membranes demand on the further investigation as well as the necessity of ABOand HLA-matching of donor-recipient pairs and requirement for immunosuppression application.

Цель. Изучить эффективность аллотрансплантации макроинкапсулированных клеток паращитовидной железы в артериальное сосудистое русло пациентам с послеоперационным гипопаратиреозом без применения иммуносупрессии. Материал и методы. За период с декабря 2010 года по ноябрь 2011 года семи пациентам было выполнено 7 аллотрансплантаций макроинкапсулированных паратироцитов, показанием к которым во всех случаях был ятрогенный гипопаратиреоз после операций на щитовидной железе. Средний возраст пациентов составил 52 [39-59] лет. В качестве доноров были выбраны пациенты, которым выполнялась паратиреоидэктомия по поводу первичного (аденома) и вторичного (обусловленного хронической почечной недостаточностью) гиперпаратиреоза. Результаты. Для трансплантации были отобраны культивированные клетки с высокой концентрацией паратгормона в культуральной жидкости (2927, 5 [1400,5-4847] пг/мл) и степенью жизнеспособности 99%. Медиана продолжительности функционирования паратиреоидного трансплантата составила 3 [1-9] месяца, в то время как, у 4 (57,1%) пациентов клеточные аллотрансплантаты сохраняли свою эндокринную функцию более 2 месяцев. В посттрансплантационном периоде клинические симптомы гиперпаратиреоза не были выявлены ни в одном случае. Заключение. У некоторых пациентов с гипопаратиреозом, развившимся после операций на щитовидной железе, паратиреоидная аллотрансплантация является эффективной терапевтической альтернативой стандартным методам лечения. Возраст доноров и реципиентов, продолжительность гипопаратиреоза не оказывали существенного влияния на длительность функционирования трансплантата. Дальнейшего изучения требуют вопросы, касающиеся пористости, биосовместимости и длительной стабильности микропористых мембран, а также необходимости
