Uszkodzenie nerwów autonomicznych
Objawy

Neuropatia autonomiczna to przewlekłe uszkodzenie nerwów autonomicznych, które kontrolują funkcje automatyczne organizmu, takie jak regulacja ciśnienia krwi, trawienie, funkcje pęcherza moczowego czy seksualne. Objawy zależą od lokalizacji uszkodzenia i mogą obejmować hipotensję ortostatyczną, tachykardię spoczynkową, gastroparezę, zaburzenia mikcji oraz dysfunkcje seksualne. W cukrzycy typu 1 rozwój neuropatii autonomicznej sercowo-naczyniowej (CAN) wiąże się z czterokrotnie wyższym ryzykiem zgonu, a ryzyko śmiertelności w ciągu 5 lat u pacjentów z zaawansowaną dysfunkcją autonomiczną wynosi około 50%. Objawy mogą być subkliniczne lub wyniszczające, a ich progresja jest zmienna i zależy od przyczyny, kontroli choroby podstawowej oraz wczesnego rozpoznania i leczenia.

Uszkodzenie nerwów autonomicznych – objawy

Uszkodzenie nerwów autonomicznych (autonomic neuropathy) to zaburzenie, które wpływa na układ nerwowy autonomiczny kontrolujący funkcje automatyczne organizmu, takie jak ciśnienie krwi, temperaturę ciała, trawienie, funkcje pęcherza moczowego czy funkcje seksualne. Jest to grupa objawów występujących, gdy dochodzi do uszkodzenia nerwów zarządzających normalnie automatycznymi funkcjami organizmu12.

Objawy uszkodzenia nerwów autonomicznych zależą od tego, które nerwy zostały uszkodzone i zwykle rozwijają się powoli, na przestrzeni lat34. W niektórych przypadkach stopień dysfunkcji autonomicznej może być subkliniczny lub nieistotny klinicznie, podczas gdy u innych pacjentów objawy mogą być wyniszczające5.

Wczesne objawy neuropatii autonomicznej

Wczesne objawy neuropatii autonomicznej mogą obejmować67:

  • Omdlenia lub zawroty głowy podczas wstawania
  • Zmiany w funkcjonowaniu jelit, pęcherza lub funkcji seksualnych
  • Niewyjaśnione nudności i wymioty podczas jedzenia

U osób z dysfunkcją autonomiczną wczesne stadium może obejmować nadciśnienie, bezdech senny lub bezsenność oraz problemy z przepływem krwi mózgowej, które prowadzą do ADD, przewlekłego głodu lub przewlekłego zmęczenia. Mogą występować również nieprawidłowe rytmy serca i częste oddawanie moczu. Pojawiają się także niewyjaśnione stany lękowe, zawroty głowy, bezsenność lub budzenie się w nocy, słaba pamięć, słaba koncentracja i napady energii, gdy powinniśmy odpoczywać8.

Objawy uszkodzenia nerwów autonomicznych w zależności od układu

Układ sercowo-naczyniowy

Uszkodzenie nerwów kontrolujących częstość akcji serca i ciśnienie krwi może powodować, że nerwy te reagują wolniej na zmiany pozycji ciała, stres, aktywność fizyczną, sen i wzorce oddychania9. Uszkodzenie może prowadzić do takich objawów jak101112:

  • Zawroty głowy i omdlenia podczas wstawania, spowodowane nagłym spadkiem ciśnienia krwi (hipotensja ortostatyczna)
  • Tachykardia spoczynkowa (przyspieszony rytm serca w spoczynku)
  • Nietolerancja wysiłku, która może wystąpić, jeśli częstość akcji serca pozostaje taka sama zamiast dostosowywać się do poziomu aktywności
  • Zawał serca bez typowych objawów ostrzegawczych, takich jak ból w klatce piersiowej

Neuropatia autonomiczna sercowo-naczyniowa (CAN) jest silnie związana ze zwiększoną śmiertelnością i w niektórych badaniach z zachorowalnością, taką jak udar, choroba wieńcowa i cichy zawał mięśnia sercowego13. Rozwój dysfunkcji autonomicznej w cukrzycy typu 1 wiąże się z czterokrotnie wyższym ryzykiem zgonu14.

Układ pokarmowy

Uszkodzenie nerwów układu pokarmowego może powodować różnorodne objawy1516:

  • Uczucie pełności po zjedzeniu kilku kęsów pokarmu
  • Utrata apetytu
  • Biegunka, zaparcia lub naprzemienne występowanie biegunki i zaparć
  • Nietrzymanie stolca
  • Wzdęcia brzucha
  • Nudności i wymioty
  • Trudności z przełykaniem
  • Zgaga

Neuropatia autonomiczna może również powodować gastroparezę – opóźnione opróżnianie żołądka17. Najbardziej obawianym i często źle leczonym objawem neuropatii autonomicznej jest ból brzucha18.

Układ moczowo-płciowy

Uszkodzenie nerwów pęcherza moczowego może utrudniać rozpoznanie, kiedy potrzebujemy oddać mocz i kiedy pęcherz jest pusty19. Problemy z układem moczowym mogą obejmować2021:

  • Trudności z rozpoczęciem oddawania moczu
  • Utrata kontroli nad pęcherzem moczowym (nietrzymanie moczu)
  • Trudności z wyczuwaniem pełnego pęcherza
  • Niemożność całkowitego opróżnienia pęcherza

Niemożność całkowitego opróżnienia pęcherza może prowadzić do częstych infekcji dróg moczowych22.

W zakresie funkcji seksualnych, uszkodzenie nerwów może powodować2324:

  • U mężczyzn: problemy z osiągnięciem lub utrzymaniem erekcji (zaburzenia erekcji), problemy z ejakulacją, przedwczesny wytrysk
  • U kobiet: suchość pochwy, obniżone libido, trudności z osiągnięciem orgazmu

Zaburzenia pocenia i regulacji temperatury

Uszkodzenie nerwów kontrolujących gruczoły potowe może powodować nadmierne pocenie się w nocy lub podczas jedzenia25. Zaburzenia pocenia mogą obejmować2627:

  • Nadmierne pocenie się (hiperhidroza)
  • Zmniejszone pocenie się lub jego brak (anhidroza)
  • Sucha skóra na stopach

Te problemy wpływają na zdolność organizmu do regulacji temperatury ciała, co może prowadzić do nietolerancji ciepła lub zimna28.

Zmiany w funkcjonowaniu źrenic

Uszkodzenie nerwów źrenic może powodować powolną reakcję źrenic na zmiany oświetlenia29. Może to prowadzić do30:

  • Trudności w dostosowaniu się do przejścia ze światła do ciemności
  • Problemy z widzeniem podczas prowadzenia pojazdu w nocy

Nieświadomość hipoglikemii

Neuropatia autonomiczna może powodować nieświadomość hipoglikemii, co oznacza, że pacjent nie odczuwa objawów niskiego stężenia glukozy we krwi31. W normalnych warunkach spadek poziomu cukru we krwi powoduje objawy takie jak drżenie, które służą jako sygnały ostrzegawcze32.

Progresja neuropatii autonomicznej

Neuropatia autonomiczna jest zazwyczaj stanem przewlekłym, a jej objawy często rozwijają się w sposób podstępny33. Progresja choroby może być różna, w zależności od przyczyny, które nerwy są dotknięte i stosowanego leczenia34.

Etapy progresji neuropatii autonomicznej

Progresję neuropatii autonomicznej można podzielić na kilka etapów3536:

  1. Wczesne stadium: Objawy są często łagodne i łatwe do przeoczenia. Pacjenci mogą czuć się nieco nietypowo, z problemami takimi jak zaburzenia ciśnienia krwi lub trawienia. To najlepszy moment na szukanie pomocy medycznej, aby spowolnić uszkodzenie nerwów.
  2. Stadium średnie: Objawy stają się bardziej stałe i wyraźne. Pacjenci mogą odczuwać zawroty głowy, mieć problemy z trawieniem lub trudności z kontrolą pęcherza moczowego. Te problemy zaczynają wpływać na codzienne życie.
  3. Stadium późne: Objawy są bardzo nasilone i trudne do opanowania. Pacjenci mogą doświadczać dużych wahań ciśnienia krwi, silnych bólów brzucha lub poważnych problemów z pęcherzem moczowym. Na tym etapie uszkodzenie nerwów autonomicznych jest znaczne.

W przypadku cukrzycowej neuropatii autonomicznej (DAN) i sercowo-naczyniowej neuropatii autonomicznej (CAN), które charakteryzują się najbardziej zaawansowanymi wzorcami testów autonomicznych wskazującymi na słabą funkcję przywspółczulną, ryzyko zgonu w ciągu 5 lat wynosi około 50%3738.

Czynniki wpływające na progresję

Progresja neuropatii autonomicznej zależy od kilku czynników3940:

  • Przyczyna neuropatii – choroby takie jak cukrzyca, choroby autoimmunologiczne czy infekcje mogą powodować różne tempa progresji
  • Kontrola choroby podstawowej – np. ścisła kontrola glikemii w przypadku cukrzycy
  • Wczesne rozpoznanie i leczenie – może spowolnić postęp choroby
  • Inne czynniki ryzyka sercowo-naczyniowego, takie jak palenie, nadciśnienie, hiperlipidemia

W wielu przypadkach przebieg neuropatii autonomicznej jest stopniowo postępujący41. W niektórych przypadkach neuropatia prowadząca do uszkodzenia zarówno małych, jak i dużych włókien nerwowych może najpierw prezentować się jako neuropatia małych włókien, zanim postępi do uszkodzenia dużych włókien42.

Rokowanie

Rokowanie zależy od konkretnego zespołu powodującego neuropatię autonomiczną43. Neuropatia autonomiczna jest nieprzewidywalnym stanem – niektórzy pacjenci mogą doświadczać częstych objawów, inni mogą przejść miesiące lub nawet lata bez żadnych objawów44.

W niektórych przypadkach, takich jak ostre neuropatie autonomiczne (np. ostra pandysautonomia, zespół Guillaina-Barrégo), rokowanie jest często dobre po ustąpieniu ostrej choroby45.

Jednakże, w poważniejszych przypadkach, objawy mogą wpływać na zdolność do pracy lub uczestnictwa w ulubionych aktywnościach. Ten stan może również powodować śmiertelne powikłania46.

Szczególne formy neuropatii autonomicznej

Neuropatia autonomiczna sercowo-naczyniowa (CAN)

Neuropatia autonomiczna sercowo-naczyniowa jest poważnym powikłaniem cukrzycy, silnie związanym z około pięciokrotnie zwiększonym ryzykiem śmiertelności sercowo-naczyniowej47. Objawia się w spektrum objawów, od tachykardii spoczynkowej i stałej częstości akcji serca po rozwój cichego zawału mięśnia sercowego48.

Objawy CAN mogą wpływać na jakość życia pacjenta i obejmują49:

  • Uczucie lekkości głowy lub zawroty głowy, szczególnie podczas wstawania
  • Kołatanie serca
  • Przyspieszony rytm serca
  • Omdlenia
  • Zmęczenie
  • Nietolerancja wysiłku

Wiele objawów CAN występuje lub nasila się przy zmianie pozycji z leżącej lub siedzącej na stojącą. Objawy takie jak zawroty głowy i zaburzenia widzenia przy wstawaniu są znane jako nietolerancja ortostatyczna50.

Neuropatia autonomiczna żołądkowo-jelitowa

Objawy powodowane przez neuropatię autonomiczną żołądkowo-jelitową w cukrzycy są istotne, ponieważ dotykają dużą część osób z cukrzycą, niezależnie od tego, czy jest to typ 1 czy 251.

Gastropareza i ogólne objawy dysfunkcji jelit, takie jak zaparcia, biegunka i ból brzucha, są najczęściej spotykane i wymagają zarówno farmakologicznych, jak i niefarmakologicznych opcji leczenia52.

Wszystkie części przewodu pokarmowego mogą być dotknięte neuropatią autonomiczną żołądkowo-jelitową, ale najczęściej spotykane są związane z dysfunkcją żołądka i jelit53.

Wpływ na jakość życia

Neuropatia autonomiczna może mieć istotny wpływ na jakość życia54. Może wpływać na zdolność wykonywania codziennych czynności i prowadzić do dyskomfortu i bólu. Może również prowadzić do poważnych powikłań, takich jak niewydolność serca, uszkodzenie nerek czy krwawienie z przewodu pokarmowego55.

Wczesne rozpoznanie i leczenie są kluczowe, aby zapobiec dalszemu postępowi choroby i poprawić wyniki leczenia5657. Pacjenci z neuropatią autonomiczną muszą ściśle współpracować ze swoim lekarzem, aby zarządzać objawami i zapobiegać powikłaniom58.

    https://patient.info/doctor/autonomic-neuropathy
    Autonomic neuropathy affects the autonomic neurons of either or both of the parasympathetic and sympathetic nervous systems. […] Several syndromes and diseases exhibit autonomic neuropathies and there is a wide variety of clinical features and presentations. […] In some patients the features are subclinical, whereas in others the dysfunction leads to significant disability. […] Autonomic neuropathies represent a complex group of disorders that preferentially target autonomic fibres and can be classified as either acute/subacute or chronic in onset. […] Of the chronic-onset forms, diabetes is the most widespread and disabling, with autonomic impairment leading to increased mortality. […] Autonomic nervous system dysfunction may present with a variety of symptoms. Orthostatic intolerance (including orthostatic hypotension or tachycardia) and sweating abnormalities (increased or decreased sweating) are common problems.

    https://emedicine.medscape.com/article/1173756-overview
    Autonomic neuropathies are a collection of syndromes and diseases affecting the autonomic neurons, either parasympathetic or sympathetic, or both. […] The autonomic nervous system modulates numerous body functions; therefore, autonomic dysfunction may manifest with numerous clinical phenotypes and various laboratory and neurophysiologic abnormalities. […] In some patients, the degree of autonomic dysfunction may be subclinical or clinically irrelevant; in others, symptoms may be disabling. […] Several clinically important features of autonomic neuropathies are treatable; therefore, the physician must be alert to these features. […] The prognosis depends on the particular syndrome causing autonomic neuropathy. In many cases, the course is gradually progressive in nature. […] In specific cases, the prognosis may be improved by controlling diabetes mellitus, limiting alcohol intake, and treating correctable syndromes or diseases as applicable to prevent progression. […] In the case of acute autonomic neuropathies, such as acute pandysautonomia and GBS, the prognosis is often good after resolution of the acute illness.

    Autonomic Dysfunction includes heartburn, headaches, high blood pressure, sleep apnea or insomnia, and cerebral blood flow issues that create ADD, chronic hunger or chronic fatigue. […] Early Autonomic Dysfunction in adults includes high blood pressure, sleep apnea or insomnia, and cerebral blood flow issues that leave us with ADD, chronic hunger or chronic fatigue. It is abnormal heart rhythms and frequent urination. It is also unexplained anxiety, dizziness or feeling lightheaded, insomnia or waking up in the night, poor memory, poor focus, and power surges when you should be at rest. […] Autonomic Dysfunction causes people to experience heartburn, headaches, intestinal distress, dizziness, excessive hunger or thirst, anxiety, sexual dysfunction, or poor sleep. […] The progression of Autonomic Dysfunction brings the inability to control the blood pressure and heart rates (A-fib, flutter, palpitations, POTS), affects the forward movement of the digestive tract, and proper breathing (sleep apnea). People experience problems with their immune system, hormone levels, and organ function. People no longer bounce back from illnesses or injury and may suffer from chronic fatigue or chronic pain.

    https://resources.healthgrades.com/right-care/symptoms-and-conditions/autonomic-neuropathy
    Autonomic neuropathy is a type of nerve damage that affects internal organs. Diabetes is a common cause of autonomic neuropathy. Your autonomic nervous system controls involuntary functions in your body, such as digestion, heart rate, and sexual arousal. Autonomic neuropathy occurs when the nerves of internal organs become damaged, causing a change in function. […] Autonomic neuropathy, or autonomic small fiber neuropathy, is damage to nerves that control internal organs. As nerve damage progresses, it disrupts the function of the organ. […] Symptoms of autonomic neuropathy vary depending on the area affected by nerve damage. […] Damage to heart and vascular nerves can cause symptoms of CAN including elevated resting heart rate, dizziness if you stand up too quickly, sudden fainting for no apparent reason, especially after standing up or changing position, heart attack without typical symptoms, such as chest pain or tightness.

    https://en.wikipedia.org/wiki/Autonomic_neuropathy
    Autonomic neuropathy (AN or AAN) is a form of polyneuropathy that affects the non-voluntary, non-sensory nervous system (i.e., the autonomic nervous system), affecting mostly the internal organs such as the bladder muscles, the cardiovascular system, the digestive tract, and the genital organs. […] The signs and symptoms of autonomic neuropathy include the following: […] Urinary bladder conditions: urinary incontinence or urinary retention which happens due to the uncoordinated contraction of the bladder. […] Gastrointestinal tract: dysphagia, abdominal pain, nausea, vomiting, malabsorption, fecal incontinence, gastroparesis, diarrhea, constipation […] Cardiovascular system: disturbances of heart rate (tachycardia, bradycardia), orthostatic hypotension, inadequate increase of heart rate on exertion

    Autonomic neuropathy occurs when there is damage to the nerves that control automatic body functions. It can affect blood pressure, temperature control, digestion, bladder function and even sexual function. […] Signs and symptoms of autonomic neuropathy depend on which nerves are damaged. They might include: Dizziness and fainting when standing, caused by a sudden drop in blood pressure. Urinary problems, such as difficulty starting urination, loss of bladder control, difficulty sensing a full bladder and inability to completely empty the bladder. Not being able to completely empty the bladder can lead to urinary tract infections. Sexual difficulties, including problems achieving or maintaining an erection (erectile dysfunction) or ejaculation problems. In women, problems include vaginal dryness, low libido and difficulty reaching orgasm. Difficulty digesting food, such as feeling full after a few bites of food, loss of appetite, diarrhea, constipation, abdominal bloating, nausea, vomiting, difficulty swallowing and heartburn. These problems are all due to changes in digestive function. Inability to recognize low blood sugar (hypoglycemia), because the warning signals, such as getting shaky, aren’t there. Sweating problems, such as sweating too much or too little. These problems affect the ability to regulate body temperature. Sluggish pupil reaction, making it difficult to adjust from light to dark and seeing well when driving at night. Exercise intolerance, which can occur if your heart rate stays the same instead of adjusting to your activity level.

    Most of the primary autonomic disorders are chronic in nature, with symptoms often initiating in an insidious fashion. However, in acute autonomic neuropathies, the onset can be dramatic with presentation as a generalized dysautonomia. In general, patients present with symptoms of both sympathetic and parasympathetic dysfunction, with or without symptoms of somatic nervous system dysfunction. […] Orthostatic hypotension is often the first recognized symptom and is typically the most disabling. […] However, other autonomic symptoms can occur before syncope, and these include impotence or ejaculatory dysfunction, decreased sweating, and urinary incontinence. […] For example, in Sj gren syndrome, dry mouth and eyes along with anhidrosis are typically the initial symptoms in affected patients. […] Many complications of autonomic neuropathy exist, as described above. The most severe are cardiac arrest, cardiac dysrhythmia, blood pressure fluctuations, and risk of cerebral and cardiac ischemia.
