Choroba hashimoto
Diagnostyka i diagnoza

Choroba Hashimoto, będąca przewlekłym autoimmunologicznym zapaleniem tarczycy, jest najczęstszą przyczyną niedoczynności tarczycy w krajach o wystarczającej podaży jodu. Diagnostyka opiera się na kompleksowej ocenie klinicznej, badaniach laboratoryjnych oraz obrazowych. Typowe objawy niedoczynności tarczycy obejmują m.in. zmęczenie, przyrost masy ciała, nietolerancję zimna, wypadanie włosów, nieregularne miesiączki i depresję. Kluczowe badania laboratoryjne to oznaczenie TSH, którego podwyższony poziom (≥4,0 mU/ml) wskazuje na niedoczynność, oraz oznaczenie wolnej tyroksyny (FT4) i trijodotyroniny (T3). Obecność przeciwciał anty-TPO (u ponad 90% pacjentów) i anty-Tg (u 50-80%) potwierdza autoimmunologiczne podłoże choroby. Ultrasonografia tarczycy wykazuje charakterystyczne cechy, takie jak hipoechogeniczność, niejednorodna struktura i zwiększone unaczynienie, co jest szczególnie pomocne w diagnostyce seronegatywnej postaci choroby.

Diagnostyka choroby Hashimoto

Choroba Hashimoto (przewlekłe autoimmunologiczne zapalenie tarczycy) jest najczęstszą przyczyną niedoczynności tarczycy w krajach rozwiniętych o wystarczającej podaży jodu, w tym w Stanach Zjednoczonych. Jest to schorzenie autoimmunologiczne, charakteryzujące się produkcją przeciwciał i aktywacją limfocytów T, które atakują gruczoł tarczowy, prowadząc do postępującego włóknienia tarczycy. Diagnostyka tej choroby wymaga kompleksowego podejścia i obejmuje ocenę objawów klinicznych, badania laboratoryjne oraz w niektórych przypadkach badania obrazowe.123

Objawy kliniczne i badanie fizykalne

Diagnoza choroby Hashimoto opiera się w pierwszej kolejności na dokładnym badaniu fizykalnym i szczegółowym wywiadzie medycznym. Lekarz poszukuje charakterystycznych objawów niedoczynności tarczycy oraz ocenia, czy występuje powiększenie tarczycy (wole). Wole jest jednym z wczesnych objawów choroby Hashimoto i często może być wykryte podczas badania szyi.456

Należy pamiętać, że objawy choroby Hashimoto mogą być niespecyficzne i przypominać inne schorzenia, co może utrudniać wczesną diagnozę. Do typowych objawów niedoczynności tarczycy w przebiegu choroby Hashimoto należą: zmęczenie, przyrost masy ciała, nietolerancja zimna, wypadanie włosów, nieregularne miesiączki, zaparcia, depresja i bóle stawów.78

Badanie fizykalne może wykazać również inne charakterystyczne cechy, takie jak: obrzęk twarzy i okolic oczu typowy dla niedoczynności tarczycy, zimna i sucha skóra, która może być szorstka i łuszcząca się, obrzęki obwodowe rąk i stóp, zgrubiałe i łamliwe paznokcie, bradykardia, podwyższone ciśnienie tętnicze (typowo nadciśnienie rozkurczowe), osłabione odruchy głębokie i charakterystyczna wydłużona faza relaksacji, powiększony język, spowolniona mowa oraz ataksja.9

Badania laboratoryjne

Badania laboratoryjne stanowią podstawę diagnostyki choroby Hashimoto. Najważniejsze oznaczenia obejmują:1011

Badania hormonów tarczycy

Oznaczenie TSH (hormon tyreotropowy) jest podstawowym i najbardziej czułym badaniem w diagnostyce niedoczynności tarczycy. Podwyższony poziom TSH wskazuje najczęściej, że gruczoł tarczowy nie produkuje wystarczającej ilości hormonu tyroksyny (T4), co sugeruje niedoczynność tarczycy lub subkliniczną niedoczynność tarczycy. We wczesnym etapie choroby Hashimoto poziom TSH może być podwyższony, a następnie dochodzi do obniżenia hormonu tyroksyny (T4) lub wolnej tyroksyny (FT4) oraz trijodotyroniny (T3).121314

Wynik wysokiego poziomu TSH wraz z niskim poziomem wolnej T4 potwierdza rozpoznanie jawnej pierwotnej niedoczynności tarczycy. W przypadku subklinicznej niedoczynności tarczycy, poziom TSH jest podwyższony, ale poziom wolnej T4 pozostaje w granicach normy.1516

Przeciwciała tarczycowe

Test na obecność przeciwciał przeciwtarczycowych jest kluczowy dla potwierdzenia autoimmunologicznego podłoża niedoczynności tarczycy. W chorobie Hashimoto najczęściej oznacza się:1718

  • Przeciwciała przeciwko peroksydazie tarczycowej (anty-TPO) – obecne u ponad 90% pacjentów z chorobą Hashimoto19
  • Przeciwciała przeciwko tyreoglobulinie (anty-Tg) – obecne u 50-80% pacjentów20

Podwyższone poziomy tych przeciwciał korelują z aktywnością choroby. Osoby z pozytywnym wynikiem na obecność przeciwciał mają wysokie prawdopodobieństwo rozwoju jawnej niedoczynności tarczycy, podczas gdy osoby z negatywnym wynikiem na obecność przeciwciał częściej prezentują subkliniczną niedoczynność tarczycy.2122

Warto zauważyć, że około 5-10% pacjentów z chorobą Hashimoto może nie mieć wykrywalnych przeciwciał we krwi, co określa się jako seronegative Hashimoto’s thyroiditis. W takich przypadkach diagnoza może opierać się na charakterystycznym obrazie ultrasonograficznym tarczycy.2324

Badania obrazowe

Badania obrazowe, szczególnie ultrasonografia tarczycy, mogą dostarczyć dodatkowych informacji diagnostycznych, zwłaszcza w przypadkach, gdy istnieje powiększenie tarczycy lub wyczuwalne są guzki tarczycy.2526

Ultrasonografia tarczycy

Badanie USG tarczycy może wykazać charakterystyczne cechy choroby Hashimoto, takie jak:2728

  • Zmniejszona echogeniczność tarczycy
  • Niejednorodna struktura
  • Zwiększone unaczynienie
  • Obecność małych torbieli
  • Rozlane powiększenie tarczycy z nieregularną powierzchnią

Ultrasonografia jest szczególnie przydatna u pacjentów z seronegatywną chorobą Hashimoto (bez wykrywalnych przeciwciał), a także do wykluczenia innych przyczyn powiększenia tarczycy, takich jak guzki tarczycy. Badanie to może również pomóc w monitorowaniu wielkości tarczycy i obecności guzków w trakcie leczenia.2930

Biopsja cienkoiglowa

Biopsja cienkoiglowa (FNA) nie jest rutynowo wykonywana w diagnostyce choroby Hashimoto, ale może być konieczna w przypadku obecności guzków tarczycy, aby wykluczyć złośliwy charakter zmian. Choroba Hashimoto jest diagnozą histologiczną, charakteryzującą się rozlanym naciekiem limfocytarnym i komórkami plazmatycznymi z tworzeniem grudek limfoidalnych wynikających z hiperplazji grudkowej i uszkodzenia błony podstawnej pęcherzyków.3132

Kryteria diagnostyczne i rozpoznanie różnicowe

Diagnoza choroby Hashimoto opiera się na kombinacji objawów klinicznych, wyników badań laboratoryjnych i obrazowych. Typowe kryteria diagnostyczne obejmują:33

  1. Obraz ultrasonograficzny pokazujący charakterystyczny hipoechogeniczny wzór choroby Hashimoto
  2. Dwa poziomy TSH we krwi ≥4,0 mU/ml w odstępie 2-6 miesięcy
  3. Obecność przeciwciał anty-TPO lub anty-Tg w surowicy (choć nie u wszystkich pacjentów)

Rozpoznanie różnicowe powinno uwzględniać inne przyczyny niedoczynności tarczycy, takie jak niedobór jodu (globalnie najczęstsza przyczyna niedoczynności tarczycy), przebyte leczenie radiojodem, wpływ niektórych leków (amiodaron, lit, interferon-alfa) czy przebyta operacja tarczycy.3435

Monitorowanie i postępowanie po diagnozie

Po zdiagnozowaniu choroby Hashimoto konieczne jest regularne monitorowanie funkcji tarczycy w celu dostosowania leczenia i zapobiegania powikłaniom.36

Pacjenci z subkliniczną niedoczynnością tarczycy i dodatnimi przeciwciałami tarczycowymi powinni być monitorowani corocznie ze względu na wysokie ryzyko progresji do jawnej niedoczynności tarczycy. Szczególnie dotyczy to pacjentów z poziomem TSH ≥10 mIU/L lub z wyraźnymi objawami klinicznymi.3738

Decyzja o rozpoczęciu leczenia lewotyroksyną powinna opierać się na wynikach badań funkcji tarczycy, uwzględniając objawy kliniczne, wiek pacjenta, choroby współistniejące, wielkość wola oraz preferencje pacjenta. Pacjenci z jawną niedoczynnością tarczycy (TSH ≥10 mIU/L i obniżony poziom wolnej T4) potwierdzoną w powtórnych badaniach powinni otrzymać leczenie zastępcze lewotyroksyną.39

Optymalny czas na podejmowanie decyzji o dostosowaniu dawki lewotyroksyny to 6-8 tygodni po rozpoczęciu terapii lub zmianie dawki, aby zapewnić wystarczający czas na ponowne ustalenie punktu nastawienia osi podwzgórze-przysadka-tarczyca.4041

Szczególne sytuacje diagnostyczne

Hashimoto bez niedoczynności tarczycy

Nie każdy pacjent z chorobą Hashimoto rozwija niedoczynność tarczycy. Diagnoza eutyreozy Hashimoto opiera się na obecności przeciwciał TPO i/lub typowym obrazie ultrasonograficznym tarczycy, ale z normalnymi poziomami TSH i T4 w surowicy. Pacjenci ci wymagają okresowych, corocznych pomiarów TSH w celu wykrycia niedoczynności tarczycy.4243

Ciąża i diagnostyka choroby Hashimoto

Oceniając funkcję tarczycy u kobiet w ciąży, ważne jest stosowanie specyficznych dla ciąży zakresów referencyjnych dla poziomów TSH i wolnej T4. Występowanie przeciwciał tarczycowych u kobiet w ciąży wiąże się z ryzykiem rozwoju niedoczynności tarczycy w trakcie ciąży, zwiększonym ryzykiem poronienia oraz niepowodzeniem zapłodnienia in vitro.4445

Warianty choroby Hashimoto

Istnieją warianty choroby Hashimoto, które mogą wymagać dodatkowej diagnostyki:46

  • Wariant związany z IgG4: bardziej wyraźna hipoechogeniczność w USG
  • Wariant włóknisty: hipoechogeniczność wraz z wyraźną guzkową strukturą miąższu

Nowoczesne podejścia diagnostyczne

W ostatnich latach badane są nowe markery, które mogą pomóc w diagnostyce choroby Hashimoto. Jednym z takich markerów jest wskaźnik liczby płytek krwi do liczby limfocytów (PLR), który jest wyższy u pacjentów z chorobą Hashimoto niż w zdrowej grupie kontrolnej. Badania wskazują, że zwiększone poziomy PLR mogą być użytecznym dodatkowym narzędziem diagnostycznym u pacjentów z chorobą Hashimoto.4748

Powikłania nierozpoznanej choroby Hashimoto

Nieleczona niedoczynność tarczycy w przebiegu choroby Hashimoto może prowadzić do szeregu powikłań, takich jak:4950

  • Choroby sercowo-naczyniowe, w tym zwiększone ryzyko zawału serca, udaru, migotania przedsionków i niewydolności serca
  • Podwyższony poziom cholesterolu LDL
  • Zaburzenia zdrowia psychicznego
  • Obrzęk śluzowaty
  • Wady wrodzone u dzieci matek z nieleczoną niedoczynnością tarczycy w ciąży

Dlatego tak ważne jest wczesne rozpoznanie i odpowiednie leczenie choroby Hashimoto.51

Podsumowanie procesu diagnostycznego

Diagnoza choroby Hashimoto wymaga kompleksowego podejścia, uwzględniającego:52

  1. Dokładny wywiad medyczny i badanie fizykalne, ze szczególnym uwzględnieniem objawów niedoczynności tarczycy i oceny tarczycy
  2. Badania laboratoryjne, w tym oznaczenie TSH, wolnej T4, T3 oraz przeciwciał przeciwtarczycowych (anty-TPO, anty-Tg)
  3. Badania obrazowe, głównie USG tarczycy, szczególnie w przypadkach z powiększeniem tarczycy lub przy braku przeciwciał przeciwtarczycowych
  4. W wybranych przypadkach biopsję cienkoiglową, zwłaszcza przy obecności guzków tarczycy

Wczesna i dokładna diagnoza choroby Hashimoto umożliwia odpowiednie leczenie i monitorowanie, co zapobiega poważnym powikłaniom zdrowotnym związanym z niedoczynnością tarczycy.5354

Regularne wizyty kontrolne u lekarza i systematyczne badania laboratoryjne są niezbędne dla pacjentów z chorobą Hashimoto, zarówno w celu dostosowania leczenia, jak i wczesnego wykrycia ewentualnych powikłań.5556

    Hashimoto thyroiditis, also known as chronic autoimmune thyroiditis or chronic lymphocytic thyroiditis, is an autoimmune disease that leads to the destruction of thyroid follicular cells through immune-mediated processes. This autoimmune condition is the most common cause of hypothyroidism in developed countries and is characterized by the formation of antithyroid antibodies and T-cell activation, which result in progressive fibrosis of the thyroid gland. Individuals with Hashimoto thyroiditis present with varying thyroid function states, including euthyroidism, subclinical hypothyroidism, overt hypothyroidism, and, in some cases, transient hyperthyroidism. […] This activity for healthcare professionals is designed to enhance the learner’s competence in identifying Hashimoto thyroiditis, performing the recommended evaluation, and implementing an appropriate interprofessional approach when managing this condition.

    Chronic autoimmune thyroiditis (more often called Hashimoto’s thyroiditis) is the most common cause of hypothyroidism in iodine-sufficient areas of the world. It occurs in up to 10 percent of the population, particularly females, and its prevalence increases with age. It is characterized clinically by gradual thyroid failure, with or without goiter formation, due to lymphocytic infiltration and autoimmune-mediated destruction of the thyroid gland involving apoptosis of thyroid epithelial cells. Nearly all patients who have high serum concentrations of antibodies against one or more thyroid antigens show an intense and diffuse lymphocytic infiltration of the thyroid, which includes predominantly thyroid-specific B and T cells. Follicular destruction (and not just a simple immune cell infiltrate) is the characteristic pathologic hallmark of autoimmune thyroiditis.

    Hashimoto’s thyroiditis is named after Hakaru Hashimoto, a Japanese doctor who was the first person to describe the condition in 1912. […] Because Hashimoto’s thyroiditis symptoms may be similar to those of other medical conditions, it is important to see your doctor for a diagnosis. […] Your doctor will check to see if you have a goiter. In addition, your doctor will likely order one or more of the following blood tests: […] If the test shows the presence of an antibody to thyroid peroxidase (a protein involved in thyroid hormone production), that’s a strong sign that you have Hashimoto’s thyroiditis. You might need to do more than one antibody test to confirm a Hashimoto’s diagnosis. […] Hashimoto’s disease treatment depends on whether your thyroid is damaged enough to cause hypothyroidism. If you don’t have hypothyroidism, or only a very mild case, your doctor might not prescribe any medication but instead just monitor your symptoms and check your thyroid hormone levels.

Blood tests can determine the amount of hormones produced by thyroid gland and pituitary gland. If thyroid is underactive, the levels of thyroid hormones are low. At the same time, the level of thyroid-stimulating hormone (TSH) is elevated since the pituitary gland tries to stimulate thyroid gland to produce more thyroid hormone. Early stage of Hashimotos thyroiditis, TSH level might be raised and a thyroxine hormone (T4) or free T4 and a triiodothyronine hormone (T3) subsequently decrease. […] An antibody test. Due to Hashimotos thyroiditis is an autoimmune disorder, the cause involves the production of certain antibodies. A blood test may confirm the presence of anti-thyroglobulin antibodies (anti-Tg) or/and antibodies against thyroid peroxidase (TPO antibodies), an enzyme normally found in the thyroid gland that plays an important role in the production of thyroid hormones.
