Niedoczynność przytarczyc
Zapobieganie i profilaktyka

Niedoczynność przytarczyc jest najczęstszym powikłaniem po całkowitej tyroidektomii, występującym w 30-60% przypadków, z podziałem na postać przejściową i trwałą (utrzymującą się powyżej 6 miesięcy). Czynniki ryzyka obejmują obustronne operacje tarczycy, autoimmunologiczne choroby tarczycy, centralną dyssekcję szyi, wole zamostkowe, niedoświadczenie chirurga oraz zaburzenia wchłaniania. Trwała niedoczynność wiąże się z zakresem dyssekcji węzłów chłonnych grupy VI, obniżeniem poziomu PTH po operacji, koniecznością dożylnej suplementacji wapnia, wyższym wiekiem i płcią żeńską. Kluczowe jest zachowanie przytarczyc in situ i ich unaczynienia, a w przypadku przypadkowego usunięcia – autotransplantacja. Przedoperacyjne przygotowanie obejmuje ocenę i suplementację wapnia, PTH oraz witaminy D, w tym podawanie alfakalcydolu, co zmniejsza ryzyko wczesnej hipokalcemii i skraca hospitalizację.

Niedoczynność przytarczyc po operacjach – najczęstsza przyczyna

Niedoczynność przytarczyc (hypoparathyroidism) jest jednym z najczęstszych powikłań po operacjach tarczycy, szczególnie po całkowitej tyroidektomii. Występowanie tego powikłania waha się od 30% do 60% przypadków, co czyni je najczęstszym długoterminowym powikłaniem po takich zabiegach1. Powikłanie to może znacząco obniżać jakość życia pacjentów oraz zwiększać koszty opieki zdrowotnej2. Niedoczynność przytarczyc może mieć charakter przejściowy lub trwały, przy czym za trwałe zaburzenie uznaje się to, które utrzymuje się powyżej 6 miesięcy po operacji3.

Czynniki ryzyka niedoczynności przytarczyc

Istnieje wiele czynników ryzyka rozwoju pooperacyjnej niedoczynności przytarczyc. Do najważniejszych należą:4

4

Dodatkowo czynnikami związanymi z wyższym ryzykiem trwałej niedoczynności przytarczyc są: zakres dyssekcji węzłów chłonnych grupy VI (szczególnie liczba usuniętych węzłów oraz obustronność dyssekcji), obniżenie poziomu PTH po operacji, konieczność i czas trwania dożylnej suplementacji wapnia, wyższy wiek, płeć żeńska oraz wykonanie operacji w ośrodku o małej liczbie przeprowadzanych zabiegów56.

Strategie zapobiegania niedoczynności przytarczyc

Techniki chirurgiczne

Kluczowym elementem w zapobieganiu niedoczynności przytarczyc jest odpowiednia technika chirurgiczna podczas operacji tarczycy. Należy dążyć do:78

  • Identyfikacji przytarczyc in situ – gruczoły powinny być zidentyfikowane, ostrożnie manipulowane i zachowane
  • Zachowania unaczynienia przytarczyc – dobra perfuzja jest kluczowa dla ich funkcjonowania
  • W przypadku przypadkowego usunięcia przytarczycy – zalecana jest rutynowa autotransplantacja

9

Technika autotransplantacji przytarczyc polega na przeniesieniu tkanki przytarczyc do innego obszaru ciała, takiego jak ramię lub mięsień klatki piersiowej. Zabieg ten może zapobiec rozwojowi pooperacyjnej niedoczynności przytarczyc, choć należy zaznaczyć, że przeszczepiona tkanka nie zawsze funkcjonuje prawidłowo10. Niemniej jednak, rutynowa autotransplantacja jest zalecana w przypadku niezamierzonego usunięcia gruczołów przytarczycznych11.

Przygotowanie przedoperacyjne

Odpowiednie przygotowanie pacjenta przed operacją może zmniejszyć ryzyko niedoczynności przytarczyc:

  • Ocena poziomu wapnia, PTH i witaminy D przed operacją12
  • Suplementacja witaminy D i wapnia przed zabiegiem w przypadku stwierdzenia niedoborów12
  • Przedoperacyjne podawanie aktywnej witaminy D (alfakalcydol) – może zmniejszyć ryzyko wczesnej hipokalcemii i skrócić czas hospitalizacji13
  • Zwiększenie spożycia produktów bogatych w wapń przed operacją – w jednym z badań wykazano, że zwiększenie spożycia produktów bogatych w wapń przez 7 dni przed operacją może wiązać się z niższym ryzykiem niedoczynności przytarczyc14

Nowe technologie w zapobieganiu niedoczynności przytarczyc

W ostatnich latach rozwijane są nowe metody identyfikacji i ochrony przytarczyc podczas operacji tarczycy:

Metoda autofluorescencji w bliskiej podczerwieni (NIRAF) – identyfikacja przytarczyc krok po kroku może skutecznie lokalizować gruczoły przytarczyczne i chronić ich funkcję. Badania kliniczne i meta-analizy potwierdziły wartość tej metody w chirurgii tarczycy, zwiększając wskaźnik rozpoznawania przytarczyc i zmniejszając częstość występowania pooperacyjnej niedoczynności przytarczyc i hipokalcemii15. Metoda ta może poprawić wskaźnik zachowania przytarczyc in situ i dodatkowo zmniejszyć występowanie przejściowej niedoczynności przytarczyc po operacji15.

Angiografia z indocyjaniną zieloną (ICG) – śródoperacyjne zastosowanie angiografii ICG może być skutecznym sposobem wykrywania przytarczyc i przewidywania ryzyka pooperacyjnej niedoczynności przytarczyc. Wcześniejsze badania i obserwacje śródoperacyjne sugerują, że może to być środek do zachowania przytarczyc in vivo, a tym samym zmniejszenia częstości występowania pooperacyjnej niedoczynności przytarczyc16.

Pooperacyjne postępowanie w zapobieganiu trwałej niedoczynności przytarczyc

Wczesne wykrywanie

Kluczowe znaczenie ma wczesne wykrywanie hipokalcemii po operacji, co pozwala na szybkie wdrożenie leczenia i zapobieganie trwałym zaburzeniom:

  • Monitorowanie poziomów wapnia i PTH po operacji17
  • Oznaczenie PTH 12-24 godzin po całkowitej tyroidektomii – zgodnie z nowymi wytycznymi18
  • Poziom PTH 46 godzin po operacji wynoszący 5,95 pmol/L może być wczesnym predyktorem trwałej niedoczynności przytarczyc19

Wczesna diagnostyka poprzez ocenę czynników predykcyjnych może zapobiec hipokalcemii i zmniejszyć chorobowość oraz śmiertelność. Wczesna ocena iPTH i skorygowanego stężenia wapnia w surowicy (CSC) po operacji szyi są najbardziej odpowiednimi testami do diagnozowania przemijającej i trwałej niedoczynności przytarczyc17.

Suplementacja wapnia i witaminy D

Profilaktyczne podawanie wapnia i witaminy D po operacji może znacząco zmniejszyć ryzyko i nasilenie hipokalcemii:

  • Profilaktyczna suplementacja doustnego wapnia elementarnego od pierwszego dnia po operacji zmniejsza częstość występowania pooperacyjnej objawowej hipokalcemii, długość pobytu w szpitalu i potrzebę stosowania wapnia parenteralnego20
  • Zalecane jest również stosowanie witaminy D17
  • Dopasowanie suplementacji w oparciu o wyniki szybkiego pooperacyjnego pomiaru PTH lub seryjnych poziomów wapnia w surowicy21

Istnieją trzy główne strategie zarządzania łagodną do umiarkowanej potencjalną lub rzeczywistą pooperacyjną niedoczynnością przytarczyc:21

  1. Empiryczne/profilaktyczne podawanie doustnego wapnia i witaminy D
  2. Selektywne podawanie doustnego wapnia i witaminy D w oparciu o szybki pooperacyjny poziom PTH
  3. Wykorzystanie seryjnych poziomów wapnia w surowicy jako wskaźnika

Dla pacjentów z wynikiem ≥5 w modelu predykcyjnym (opartym na zidentyfikowanych czynnikach ryzyka) zalecana jest rutynowa profilaktyczna suplementacja wapnia, nawet jeśli po operacji nie stwierdza się niedoczynności przytarczyc. Natomiast dla pacjentów z wynikiem <5 nie zaleca się profilaktycznej suplementacji wapnia; jeśli u pacjenta w późniejszym etapie rozwinie się hipokalcemia, można wdrożyć terapeutyczną suplementację wapnia22.

Model predykcyjny

Opracowanie modelu predykcyjnego niedoczynności przytarczyc po operacji tarczycy pozwala na selektywne wdrażanie rutynowej profilaktycznej suplementacji wapnia u pacjentów po operacji raka tarczycy. Głównym celem jest znalezienie znaczących czynników ryzyka, które mogą wpływać na pooperacyjną niedoczynność przytarczyc, stworzenie na tej podstawie skutecznego modelu predykcyjnego i wykorzystanie go do selektywnego wdrażania rutynowej profilaktycznej suplementacji wapnia u pacjentów po operacji raka tarczycy23.

Długoterminowe zapobieganie niedoczynności przytarczyc

Długoterminowe zarządzanie niedoczynnością przytarczyc powinno obejmować co najmniej początkowy udział endokrynologa. Niezbędne są analogi witaminy D (np. kalcytriol [Rocaltrol]), a typowo stosowane są również diuretyki tiazydowe i modyfikacja diety24.

Pacjenci z niedoczynnością przytarczyc muszą rozumieć znaczenie regularnego przyjmowania suplementów wapnia i kalcytriolu. Kalcytriol to forma witaminy D stosowana w leczeniu i zapobieganiu niskim poziomom wapnia we krwi. Osoby te muszą również regularnie wykonywać badania krwi w kierunku wapnia, fosforu i czynności nerek. Okresowe monitorowanie jest ważne, aby upewnić się, że organizm dobrze reaguje na suplementy i utrzymuje odpowiednie poziomy tych substancji. Celem jest utrzymanie poziomu wapnia w zakresie dolnej normy, aby kontrolować objawy i uniknąć hiperkalciurii25.

Nowe terapie w zapobieganiu i leczeniu niedoczynności przytarczyc

W ostatnich latach rozwijane są nowe metody leczenia niedoczynności przytarczyc:

  • Rekombinowany ludzki PTH (rhPTH [1-84]) – choć nie jest zalecany w rutynowym leczeniu niedoczynności przytarczyc, jak wskazano w dokumencie konsensusowym, kilka amerykańskich i europejskich agencji ds. leków zatwierdziło jego stosowanie u wybranych pacjentów z przewlekłą niedoczynnością przytarczyc, którzy nie mogą być odpowiednio kontrolowani standardowym leczeniem26
  • Indukcja komórek macierzystych – badania prowadzone przez Dr Diane Krause koncentrują się na indukowaniu komórek macierzystych do przekształcania się w komórki przypominające przytarczyce. Ostatnio zespół badawczy z powodzeniem stworzył komórkę macierzystą, która może produkować to samo RNA co gruczoł przytarczyczny, co stanowi znaczący kamień milowy na drodze do stworzenia komórki, która może produkować hormony gruczołu przytarczycznego, aby złagodzić cierpienie wielu kobiet27

Świadomość i edukacja

Światowy Dzień Świadomości Niedoczynności Przytarczyc, obchodzony 1 czerwca każdego roku, zwiększa świadomość na temat niedoczynności przytarczyc i potrzeby poprawy edukacji, profilaktyki i leczenia tego słabo rozumianego schorzenia28.

Najważniejszym sposobem uniknięcia niedoczynności przytarczyc jest znalezienie doświadczonego chirurga do przeprowadzenia operacji przytarczyc lub tarczycy. „Akceptowalny” wskaźnik niedoczynności przytarczyc spowodowanej przez chirurga podczas operacji gruczołów tarczycy lub przytarczyc wynosi około 1% lub mniej, jak podaje literatura medyczna28.

Edukacja pacjenta jest kluczowym elementem zapobiegania i zarządzania niedoczynnością przytarczyc. Obejmuje to informowanie o znaczeniu przestrzegania zaleceń dotyczących leków, modyfikacji diety i rozpoznawania objawów hipokalcemii. Poinformowani pacjenci są bardziej skłonni do przestrzegania leczenia i rozpoznawania, kiedy należy szukać pomocy medycznej29.

Wnioski

Zapobieganie niedoczynności przytarczyc wymaga kompleksowego podejścia obejmującego odpowiednią technikę chirurgiczną, identyfikację czynników ryzyka, przedoperacyjne przygotowanie pacjenta, wykorzystanie nowych technologii śródoperacyjnych oraz odpowiednie postępowanie pooperacyjne. Dzięki tym strategiom można znacząco zmniejszyć częstość występowania i nasilenie tego powikłania, poprawiając jakość życia pacjentów i zmniejszając koszty opieki zdrowotnej.

Kluczowe elementy profilaktyki to:3031

  • Zachowanie przytarczyc in situ podczas operacji
  • Zachowanie unaczynienia przytarczyc
  • Autotransplantacja przytarczyc w przypadku ich przypadkowego usunięcia
  • Optymalizacja poziomu witaminy D przed operacją
  • Wczesne wykrywanie i leczenie hipokalcemii po operacji
  • Regularne monitorowanie poziomu wapnia i PTH

Trwała niedoczynność przytarczyc ma długotrwałe konsekwencje zarówno dla obiektywnego, jak i subiektywnego samopoczucia pacjenta, dlatego należy jej zapobiegać, gdy tylko jest to możliwe30.

    Hypoparathyroidism (hypoPT) is the most common complication following bilateral thyroid operations. Thyroid surgeons must employ strategies for minimizing and preventing post-thyroidectomy hypoPT. […] Risk factors for post-thyroidectomy hypoPT include bilateral thyroid operations, autoimmune thyroid disease, central neck dissection, substernal goiter, surgeon inexperience, and malabsorptive conditions. Medical and surgical strategies to minimize perioperative hypoPT include optimizing vitamin D levels, preserving parathyroid blood supply, and autotransplanting ischemic parathyroid glands. […] Effective management of mild to moderate potential or actual postoperative hypoPT can be achieved by administering either empiric/prophylactic oral calcium and vitamin D, selective oral calcium, and vitamin D based on rapid postoperative PTH level(s), or serial serum calcium levels as a guide. […] Permanent hypoPT has long-term consequences for both objective and subjective well-being, and should be prevented whenever possible.

    The incidence of permanent hypoparathyroidism was closely associated with the extent of level VI dissection, particularly regarding the number of lymph nodes removed and whether the dissection was bilateral. […] The severity of post-operative hypocalcemia was demonstrated by the decrease in PTH levels, as well as the need for and duration of intravenous calcium supplementation. […] Thus, analyzing the predictive factors for permanent hypoparathyroidism is invaluable in clinical practice to identify patient subgroups that may benefit from early intervention, thereby minimizing the long-term morbidity associated with the disease.

    There are no specific actions to prevent hypoparathyroidism. However, if you’re scheduled to have thyroid or neck surgery, talk to your surgeon about the risk of damage to your parathyroid glands during the procedure. Your health care provider may choose to test your calcium, parathyroid hormone and vitamin D levels and have you begin taking supplements if needed before surgery. […] Parathyroid autotransplantation may be an option to reduce the chances of postoperative hypoparathyroidism. The surgeon works to preserve parathyroid tissue in the neck during the procedure. However, occasionally the surgeon may need to move parathyroid tissue to another area of the body, such as the arm or the chest muscle. Transplanted parathyroid tissue does not always function. […] If you’ve had surgery or radiation involving your thyroid or neck, watch for signs and symptoms that could indicate hypoparathyroidism, such as a tingling or burning sensation in your fingers, toes or lips, or muscle twitching or cramping.

    Prevention of hypoparathyroidism with the use of calcium-rich foods in the total thyroidectomy pre-operative period […] Background: Transient hypocalcemia after total thyroidectomy (TT) is a common surgical complication. […] The objectives of this study were to evaluate the incidence of hypoparathyroidism with the use of calcium-rich foods in the pre-operative period of TT, followed by a measurement of PTH performed 12 hours after such procedure. […] Methods: A preliminary study with 31 patients earmarked for TT. Patients were divided into two groups: (A) without calcium-rich foods intake in the TT pre-operative period; and (B) with the intake of calcium-rich foods, in the TT pre-operative period. […] Beginning of the use of these foods has been standardized as being seven days before surgery, due to the slower calcium intestinal absorption process. […] Results: Group B, when compared to A, showed a significant difference between PTH values, before and after surgery (p value 0.001).

    Hypoparathyroidism is an important factor that seriously affects the quality of life of patients after thyroidectomy. […] The step-by-step NIRAF parathyroid identification method can effectively locate the parathyroid gland and protect its function. […] Clinical research reports and meta-analyses have confirmed its value in thyroid surgery and can increase the recognition rate of parathyroid glands and reduce the incidence of postoperative hypoparathyroidism and hypocalcemia. […] The incidence of postoperative temporary parathyroidism and hypocalcemia in the NIRAF group was also lower than that in the control group, and postoperative PTH recovery in the NIRAF group was faster than that in the control group. […] The step-by-step near-infrared autofluorescence parathyroid identification method can be used to effectively locate parathyroid glands and protect their function. This method may improve the in situ preservation rate of parathyroid glands and further reduce the occurrence of temporary parathyroidism after surgery.

[…] Parathyroid autotransplantation can prevent the development of PoH. […] In order to prevent permanent hypoparathyroidism, it is recommended to confirm the presence of the parathyroid glands after thyroidectomy and to autotransplant any unintentionally excised glands. […] The in situ preservation of the parathyroid glands is of critical importance in preventing permanent PoH after total thyroidectomy. […] In our study, PTH levels of patients who developed PoH returned to normal within 28 days on average. […] Measuring PTH levels during the postoperative 46 h can allow early discharge of patients at low risk of developing hypoparathyroidism and the early treatment of high-risk patients. […] A postoperative 46-h PTH level of 5.95 pmol/L was found to be an early predictor of permanent PoH.

    The insufficiency or deficiency of VD is an independent preoperative predictor, contributing to postsurgical hypocalcemia. Its measurement is suggested routinely as a first step in preventing post-operative hipocalcemia. […] Prophylactic supplementation of oral calcium from day 1 postoperative reduces the incidence of postoperative symptomatic hypocalcemia, length of hospital stays and the need for using parenteral calcium in the different schemes. […] It is a known fact to every surgeon that in order to prevent postoperative hypoparathyroidism while performing thyroid surgeries, the best effort must be made to avoid any kind of damage, either directly to the glands or to the blood supply of the parathyroids. […] Based in the findings described above, many groups have developed protocols that include perioperative iPTH and calcium serum levels in order to classify their patients within risk groups and allowing either an early discharge or the establishing of an early in-hospital treatment for thyroidectomized patients using calcium supplements and adjusting surveillance. This has reduced emergency room readmissions as well as prolonged unjustified hospitalizations, improving the quality of life and therefore reducing costs.

    Hypoparathyroidism (hypoPT) is the most common complication following bilateral thyroid operations. Thyroid surgeons must employ strategies for minimizing and preventing post-thyroidectomy hypoPT. […] Risk factors for post-thyroidectomy hypoPT include bilateral thyroid operations, autoimmune thyroid disease, central neck dissection, substernal goiter, surgeon inexperience, and malabsorptive conditions. Medical and surgical strategies to minimize perioperative hypoPT include optimizing vitamin D levels, preserving parathyroid blood supply, and autotransplanting ischemic parathyroid glands. […] Effective management of mild to moderate potential or actual postoperative hypoPT can be achieved by administering either empiric/prophylactic oral calcium and vitamin D, selective oral calcium, and vitamin D based on rapid postoperative PTH level(s), or serial serum calcium levels as a guide. […] Permanent hypoPT has long-term consequences for both objective and subjective well-being, and should be prevented whenever possible.

    However, prophylactic calcium supplementation is not recommended for patients with PTC with a score of less than 5; if the patient develops hypocalcemia at the later stage, therapeutic calcium supplementation can then be implemented. […] For patients with PTC with a score of 5, routine prophylactic calcium supplementation is recommended even if no hypoparathyroidism is found after surgery. However, prophylactic calcium supplementation is not recommended for patients with PTC with a score of less than 5; if the patient develops hypocalcemia at the later stage, therapeutic calcium supplementation can then be implemented to improve their prognosis.

    The core goal of this article is to find some meaningful risk factors that can affect the postoperative hypoparathyroidism of thyroid cancer, create an effective prediction model on this basis, and use it to selectively implement routine prophylactic calcium supplementation for patients after thyroid carcinoma surgery. […] A previous study has shown that prophylactic calcium supplementation after surgery can reduce the risk of hypoparathyroidism and hypocalcemia, thus reducing the incidence of postoperative complications related to thyroid carcinoma. […] Therefore, it is particularly important to clarify the risk factors of hypoparathyroidism after thyroid carcinoma surgery. […] Routine prophylactic calcium supplementation is recommended for PTC patients with a score greater than or equal to 5, although there are no clinical symptoms of postoperative hypocalcemia caused by hypoparathyroidism.

    Hypoparathyroidism most commonly occurs after inadvertent damage or removal of parathyroid glands during neck surgery. […] Most head and neck surgeons carefully track this complication with intra- and postoperative monitoring of calcium and PTH levels. […] It is important to ensure repletion to normal levels of vitamin D and magnesium in these patients. […] Long-term management of hypoparathyroidism should include at least initial involvement of an endocrinologist. Vitamin D analogues are essential (e.g., calcitriol [Rocaltrol]), and thiazide diuretics and dietary modification are typically used as well.

    People suffering from hypoparathyroidism need to understand the importance of regularly taking calcium and calcitriol supplements. Hypoparathyroidism is a condition that causes low levels of parathyroid hormone, which plays a key role in regulating your body’s calcium levels. Calcitriol is a form of vitamin D used to treat and prevent low levels of calcium in the blood. […] These individuals also need to regularly get blood tests for calcium, phosphorus, and kidney function. Periodic monitoring is a medical term for getting regular check-ups. This is important to ensure the body is reacting well to the supplements and is maintaining the right levels of these substances. The goal of this is to keep their calcium levels within a low-normal range to manage their symptoms and avoid a condition known as hypercalciuria. […] By taking their medications as directed and getting regular check-ups, patients can control their symptoms and avoid potential complications.

    The authors recommend treatment with oral calcium salts and active vitamin D analogs. […] Although recombinant human PTH (rhPTH [184]) is not recommended in the routine treatment of hypoparathyroidism, as stated in the consensus document, several American and European drug agencies have approved its use in selected patients with chronic hypoparathyroidism who cannot be adequately controlled with standard treatment. […] This consensus document and the other recently published guides coincide on most of the key points referring to the prevention and treatment of hypoparathyroidism.

    Dr. Diane Krause has leveraged a pair of WHRY pilot grants in taking major steps toward inducing stem cells to become parathyroid-like cells. Most recently, she secured a substantial two-year grant from the National Cancer Institute to advance progress toward her goal of making up for missing or malfunctioning parathyroid glands, a condition mostly found in women. This research presents a promising opportunity to achieve a long-sought cure for hypoparathyroidism, in which patients lack the hormone produced by the parathyroid gland, leading to calcium deficiency and many health problems, from painful muscle spasms to heart failure. […] In a paper recently featured in the journal Endocrinology, Dr. Krause described how her team has successfully created a stem cell that can produce the same RNA as a parathyroid gland, a significant milestone along the path toward creating a cell that can produce the hormones of a parathyroid gland to relieve the suffering of many women.

    World Hypoparathyroidism Awareness Day, observed on June 1 each year, brings increased awareness of hypoparathyroidism and the need for improvements in education, prevention, and treatment for this poorly understood condition. […] The most important way to avoid hypoparathyroidism is to find an experienced surgeon to perform your parathyroid or thyroid surgery. The „acceptable” rate of a surgeon causing hypoparathyroidism during an operation on the thyroid or parathyroid glands is about 1% or less, as reported in the medical literature. […] Ultimately, reducing the incidence of hypoparathyroidism lies in the hands of the patients. People should be educated about hypoparathyroidism as a life-changing complication prior to undergoing surgery on their thyroid or parathyroid glands. People should check on the experience of their surgeons.
