Zakażenie mrsa
Objawy

Zakażenie MRSA (methicillin-resistant Staphylococcus aureus) charakteryzuje się opornością na metycylinę i wiele innych antybiotyków, co komplikuje terapię. Klinicznie infekcja może przebiegać od bezobjawowego nosicielstwa, przez zakażenia skóry i tkanek miękkich (cellulitis, czyraki, ropnie, karbunkuły, liszajec), aż po ciężkie, zagrażające życiu zakażenia narządowe i ogólnoustrojowe, takie jak bakteriemia, zapalenie wsierdzia, osteomyelitis czy martwicze zapalenie płuc. Objawy miejscowe obejmują zaczerwienienie, obrzęk, ból, sączenie ropy oraz wolniejsze gojenie ran, natomiast objawy systemowe to gorączka >38°C lub hipotermia <36°C, dreszcze, tachykardia, tachypnoe, splątanie i objawy niewydolności narządowej. Okres inkubacji wynosi 1-10 dni, a śmiertelność w zależności od lokalizacji zakażenia waha się od 5% do 60%, z najwyższą w bakteriemii (20-50%) i zapaleniu wsierdzia (30-37%).

Zakażenie MRSA – objawy i przebieg

Zakażenie MRSA (methicillin-resistant Staphylococcus aureus) to infekcja wywoływana przez szczep gronkowca złocistego oporny na metycylinę oraz wiele innych antybiotyków. Zakażenie MRSA może przebiegać w różny sposób – od bezobjawowego nosicielstwa, przez infekcje skórne, aż po ciężkie, zagrażające życiu infekcje narządowe i ogólnoustrojowe.12

Wczesne objawy zakażenia skóry i tkanek miękkich

Zakażenie MRSA najczęściej rozpoczyna się jako zakażenie skóry. Wczesne objawy zakażenia MRSA obejmują:34

  • Niewielki guzek lub ranę, która może przypominać ukąszenie owada lub pająka
  • Zaczerwienienie, obrzęk i ból w miejscu infekcji
  • Uczucie ciepła w okolicy zmiany
  • Sączenie się ropy lub płynu z rany
  • Wolniejsze gojenie się rany

56

We wczesnym stadium infekcji MRSA typowo pojawia się jako uniesiony guzek na skórze, który może być obrzęknięty, bolesny i ciepły w dotyku. Z czasem zmiana staje się bardziej bolesna i może zacząć wydzielać ropę lub inny wysięk.78

Progresja zakażenia skóry i tkanek miękkich

Bez odpowiedniego leczenia, zakażenie MRSA może szybko przekształcić się w głębokie, bolesne czyraki lub ropnie wymagające chirurgicznego drenażu.9 Infekcja może postępować następująco:1011

  • Początkowo niewielka, zaczerwieniona zmiana przypominająca ukąszenie pająka lub wyprysk
  • Postęp do większego, bolesnego, zaczerwienionego i obrzękniętego obszaru
  • Formowanie się ropnia wypełnionego ropą, który może pęknąć i uwalniać zawartość
  • Możliwe tworzenie wielu ognisk zakażenia, gdy bakterie ze sączącego się ropnia rozprzestrzeniają się na inne obszary skóry

1213

MRSA może wywoływać różne rodzaje zakażeń skóry, w tym:1415

  • Zapalenie tkanki łącznej (cellulitis) – zakażenie skóry lub tkanki podskórnej, rozpoczynające się jako małe czerwone guzki
  • Czyraki – ropne zakażenia mieszków włosowych
  • Ropnie – skupiska ropy w skórze lub pod skórą
  • Jęczmień – zakażenie gruczołu łojowego powieki
  • Karbunkuły – zakażenia większe niż ropień, zwykle z kilkoma otworami na skórze
  • Liszajec – zakażenie skóry z pęcherzami wypełnionymi ropą

Nieleczone zakażenie MRSA może rozprzestrzeniać się, powodując powiększanie się obszaru zajętego przez infekcję, a w przypadku głębszych zakażeń także gorączkę, dreszcze i ogólne złe samopoczucie.1617

Systemowe i narządowe zakażenia MRSA

W niektórych przypadkach bakterie MRSA nie pozostają ograniczone do skóry, ale mogą przedostawać się głębiej do organizmu, powodując potencjalnie zagrażające życiu zakażenia kości, stawów, ran pooperacyjnych, krwiobiegu, zastawek serca i płuc.1819

Objawy systemowego zakażenia MRSA mogą obejmować:2021

  • Wysoka gorączka (powyżej 38°C) lub hipotermia (poniżej 36°C)
  • Dreszcze
  • Trudności w oddychaniu
  • Zawroty głowy
  • Splątanie lub dezorientacja
  • Bóle mięśniowe
  • Obrzęk i tkliwość w zajętej części ciała
  • Przyspieszone tętno
  • Przyspieszona częstość oddechów

2223

W zależności od miejsca zakażenia, MRSA może powodować specyficzne objawy w różnych układach:2425

Zakażenie płuc (zapalenie płuc MRSA)

2627

CA-MRSA (community-associated MRSA) może powodować groźne, martwicze zapalenie płuc u wcześniej zdrowych osób. Charakteryzuje się ciężkimi objawami oddechowymi, wysoką gorączką, krwiopluciem i hipotonią.28

Zakażenie krwi (bakteriemia i posocznica MRSA)
  • Gwałtownie narastająca gorączka i dreszcze
  • Niskie ciśnienie krwi
  • Przyspieszone tętno lub słabe tętno
  • Splątanie, dezorientacja lub zaburzenia mowy
  • Duszność
  • Spocona, zimna lub blada skóra

2930

Bakteriemia MRSA jest często obserwowana u pacjentów oddziałów intensywnej terapii z cewnikami centralnymi.31 Bez odpowiedniego leczenia, posocznica MRSA może prowadzić do wstrząsu septycznego i niewydolności wielonarządowej.32

Zakażenie kości i stawów
  • Ból, obrzęk i zaczerwienienie wokół zakażonego obszaru
  • Gorączka i dreszcze
  • Zwiększone zmęczenie
  • W przypadku zapalenia szpiku kostnego (osteomyelitis): długotrwały, intensywny ból kości
  • W przypadku zapalenia stawów (septic arthritis): nagły, silny ból stawów i ograniczenie ruchomości

3334

Zakażenie zastawek serca (infekcyjne zapalenie wsierdzia)
  • Gorączka i dreszcze
  • Nowy lub zmieniony szmer serca
  • Duszność
  • Bóle stawów i mięśni
  • Zmęczenie
  • Poty nocne
  • Utrata wagi

3536

MRSA jest ważną przyczyną bakteryjnego zapalenia wsierdzia, które może powodować śmiertelność u około jednej trzeciej zakażonych pacjentów (30-37%).37

Czynniki ryzyka ciężkiego przebiegu zakażenia MRSA

Niektóre osoby są bardziej narażone na rozwój ciężkiego zakażenia MRSA:3839

  • Osoby starsze
  • Pacjenci domów opieki
  • Osoby z zaburzeniami czynności narządów
  • Pacjenci z obniżoną odpornością
  • Osoby hospitalizowane, szczególnie na oddziałach intensywnej terapii
  • Pacjenci z cewnikami naczyniowymi lub innymi urządzeniami medycznymi

Śmiertelność z powodu MRSA zależy od miejsca zakażenia i może wynosić od 5% do 60%, przy czym jest wyższa wśród osób starszych, z chorobami współistniejącymi oraz przebywających w domach opieki.40 W przypadku bakteriemii MRSA, jednej z poważniejszych postaci zakażenia, wskaźnik śmiertelności wynosi od 20% do 50%.41

Różnice w przebiegu CA-MRSA i HA-MRSA

Wyróżnia się dwa główne typy zakażeń MRSA w zależności od miejsca nabycia:4243

  • CA-MRSA (community-associated MRSA) – zakażenia pozaszpitalne:
    • Najczęściej manifestują się jako zakażenia skóry i tkanek miękkich
    • Często mogą być leczone antybiotykami doustnymi
    • Zazwyczaj łatwiejsze do leczenia niż HA-MRSA
    • Mimo to, do 70% zakażeń skóry CA-MRSA nawraca po skutecznym leczeniu
  • HA-MRSA (healthcare-associated MRSA) – zakażenia szpitalne:
    • Częściej wywołują ciężkie, inwazyjne zakażenia
    • Zwykle wymagają leczenia antybiotykami dożylnymi
    • Mogą prowadzić do poważnych infekcji narządowych
    • Związane z wyższą śmiertelnością

44

Czas inkubacji i przebieg zakażenia MRSA

Okres inkubacji MRSA (czas między zakażeniem a wystąpieniem objawów) waha się od 1 do 10 dni.45 Czas gojenia się zakażeń MRSA jest bardzo zróżnicowany i zależy od ciężkości infekcji oraz ogólnego stanu zdrowia pacjenta.46

W przypadku łagodnych zakażeń skóry MRSA, poprawa może nastąpić w ciągu kilku dni od rozpoczęcia leczenia. Głębsze lub bardziej rozległe zakażenia skórne, takie jak ropnie, mogą wymagać kilku tygodni lub więcej leczenia i pielęgnacji rany.47

Bez odpowiedniego leczenia zakażenie MRSA może szybko się rozprzestrzeniać i prowadzić do poważnych powikłań, takich jak martwicze zapalenie powięzi, zapalenie szpiku kostnego, zapalenie stawów, zapalenie płuc czy zapalenie wsierdzia.4849

Rozpoznanie i leczenie zakażenia MRSA

Wczesne rozpoznanie i leczenie zakażenia MRSA jest kluczowe dla zapobiegania rozprzestrzenianiu się infekcji i rozwojowi poważnych powikłań.5051

Kiedy szukać pomocy medycznej

Należy natychmiast zgłosić się do lekarza, jeśli zauważy się następujące objawy:5253

  • Obszar skóry, który jest czerwony, bolesny, opuchnięty lub ciepły
  • Rana, która nie goi się lub szybko się powiększa
  • Wypełniony ropą guzek lub rana
  • Gorączka towarzysząca zmianom skórnym
  • Nowe objawy w trakcie lub po leczeniu zakażenia MRSA

W przypadku wystąpienia objawów ciężkiego zakażenia należy natychmiast udać się na oddział ratunkowy:5455

  • Splątanie, dezorientacja lub zaburzenia mowy
  • Wysoka gorączka, dreszcze lub objawy grypopodobne
  • Przyspieszone tętno lub słabe tętno
  • Duszność
  • Spocona, zimna lub blada skóra
  • Sine, szare lub blade zabarwienie skóry, warg lub języka

Diagnostyka zakażenia MRSA

W celu potwierdzenia zakażenia MRSA, lekarz może:5657

  • Pobrać wymaz lub inną próbkę do analizy laboratoryjnej (np. z rany, nosa, krwi)
  • Zlecić badania krwi w celu oceny nasilenia infekcji
  • W przypadku podejrzenia zakażenia narządów wewnętrznych – zlecić odpowiednie badania obrazowe

Ważne jest, by pamiętać, że nie można określić, czy zakażenie jest spowodowane przez MRSA tylko na podstawie wyglądu – konieczne są badania laboratoryjne.58

Leczenie zakażeń MRSA

Zakażenia MRSA są trudniejsze do leczenia niż zwykłe zakażenia gronkowcowe, ponieważ bakterie są oporne na wiele powszechnie stosowanych antybiotyków. Mimo to, istnieją antybiotyki skuteczne w leczeniu MRSA.5960

Leczenie zakażeń MRSA może obejmować:6162

  • W przypadku zakażeń skóry:
    • Chirurgiczne opracowanie i drenaż ran/ropni
    • Antybiotyki miejscowe lub doustne
    • Odpowiednia pielęgnacja rany
  • W przypadku ciężkich lub inwazyjnych zakażeń:
    • Hospitalizacja
    • Antybiotyki podawane dożylnie
    • W razie potrzeby – leczenie chirurgiczne ogniska zakażenia

Czas trwania antybiotykoterapii zależy od ciężkości zakażenia – od kilku dni do kilku miesięcy.63 Ponad połowa wszystkich przypadków MRSA jest skutecznie leczona antybiotykami, a większość zakażeń skóry MRSA jest pomyślnie leczona. Jednak poważne zakażenia, takie jak zapalenie płuc, zapalenie wsierdzia i bakteriemia, mogą szybko się pogarszać, zanim lekarz zdąży znaleźć skuteczne leczenie.64

Nawet po skutecznym leczeniu zakażenia MRSA mogą nawracać – do 70% zakażeń skóry powraca po początkowym wyleczeniu. Może to być spowodowane kolonizacją MRSA u osób z najbliższego otoczenia lub długotrwałym przeżywaniem bakterii na przedmiotach i powierzchniach w otoczeniu pacjenta.65

Monitorowanie i zapobieganie nawrotom

Po leczeniu zakażenia MRSA ważne jest:6667

  • Ścisłe przestrzeganie zaleceń lekarza dotyczących przyjmowania antybiotyków (nawet jeśli objawy ustąpiły)
  • Regularne kontrole lekarskie w celu oceny skuteczności leczenia
  • Natychmiastowe zgłaszanie nowych objawów w trakcie lub po leczeniu
  • W przypadku nawracających zakażeń – konsultacja z lekarzem w celu ustalenia przyczyn
  • Stosowanie środków higieny i dezynfekcji w celu zapobiegania ponownemu zakażeniu

Zakażenie MRSA zawsze powinno być leczone przez lekarza. Istotne jest, aby ściśle przestrzegać instrukcji dotyczących leczenia, które zaleca lekarz. W przypadku pojawienia się nowych objawów podczas leczenia lub po nim, należy niezwłocznie skontaktować się z lekarzem.68

    https://www.medicalnewstoday.com/articles/mrsa-early-stages
    MRSA may enter the body via a break in the skin, such as a cut or scrape. In the early stages, the affected skin typically forms a bump that may be red, swollen, and warm to the touch. It may become painful and may leak pus or drainage. […] Most infections begin in an area of broken skin, such as a cut or scrape. The infected area may then form a bump or sore, which may be: red, though this may be difficult to see on darker skin; swollen; painful; warm to the touch; leaking pus or drainage. […] In the initial stages, an MRSA infection typically appears as a raised bump on the skin. The bump may appear swollen, feel hot to the touch, and, on lighter skin, may appear red. The bump may then start to feel painful and begin oozing pus or drainage. […] In the early stages, an MRSA infection may cause a raised bump on the skin, which may be swollen and warm to the touch. As the infection develops, the bump may become more painful and ooze pus or drainage. Without appropriate treatment with oral antibiotics, the infection can enter the bloodstream and may infect other organs and tissues. At this stage, IV antibiotics are necessary to help prevent serious complications.

    MRSA symptoms vary by where you’re infected. Some symptoms common to many types of MRSA infections include: […] A rash or area of skin that’s red, discolored, painful, swollen, or filled with pus or fluid. MRSA skin infections can sometimes be mistaken for spider bites. […] If you have a skin infection, your provider will surgically treat and drain your wounds. They might give you topical or oral antibiotics. You’ll need to be treated in the hospital if you have a severe or invasive MRSA infection. […] CA-MRSA, especially skin infections, can be easier to treat than HA-MRSA. But up to 70% of MRSA skin infections come back (recur) after successful treatment. This might be because other people you live with or are around a lot are colonized with MRSA, or because MRSA lives on objects and surfaces for a long time, where it can reinfect you.

    Staph (staphylococcal) infection stages range from mild to extremely serious and even life-threatening. However, if you catch and treat it early, you can keep it from becoming more serious. […] In the early stage, Staphylococcus is confined to a small area, usually discolored and sore. It may look like a small pimple or boil. It could be swollen, and sometimes you’ll have pus or drainage. […] The body can often ward off the infection at this stage. If not, the infection can spread until its treated with antibiotics. […] MRSA is a type of staph infection, but the bacteria that cause don’t go away in response to antibiotics. Antibiotic resistance makes MRSA infections difficult to treat. MRSA is so difficult to treat that the Centers for Disease Control and Prevention considers it a „serious threat.”

  • #13 MRSA: Symptoms, Causes, Treatments, and Your Risk
    https://www.webmd.com/skin-problems-and-treatments/understanding-mrsa
    MRSA most often appears as a skin infection, such as a boil or abscess (a mass that is full of pus). At first, it might look like a pimple, but it can turn into a hard, painful lump that is red and filled with pus. An infection also might look like a skin lesion, or an area of skin thats different from the rest of your skin, like a sore. If there are red streaks branching out from the lesion, that may be a sign that the infection is spreading to your bloodstream. […] The symptoms of a MRSA infection depend on where the infection is. MRSA often gets into a skin injury such as a cut, scrape, or burn. It also might infect a surgical wound. […] The infected area may feel painful and warm to the touch. If its a skin injury, such as a cut, it may hurt more than a typical skin injury would. […] MRSA can cause many other symptoms because it can get into your bloodstream and then settle elsewhere in the body. Along with pain at the site of the infection, the symptoms may include: Fever, Chest pain, Shortness of breath, Fatigue, Muscle or joint pain, A rash.

    What are the signs and symptoms of a MRSA infection? […] Symptoms and Signs include cellulitis, boils, abscesses, sty, impetigo, carbuncles, and rash. […] The incubation period (time between infection and start of symptoms) is variable and may depend on the particular strain of MRSA and the person’s immunity. Most MRSA infections are skin and soft tissue infections that produce the following signs and symptoms: […] Cellulitis is an infection of the skin or the fat and tissues under the skin, usually starting as small red bumps on the skin. It includes redness, swelling of the tissues, warmth, and tenderness. […] Boils (pus-filled infections of hair follicles) […] Abscesses (collections of pus in or under the skin) […] Sty (an infection of an oil gland of the eyelid) […] Carbuncles (infections larger than an abscess, usually with several openings to the skin)

    https://www.medicinenet.com/mrsa_infection/article.htm
    Impetigo (skin infection with pus-filled blisters) […] Rashes like a sunburn or skin redness (skin appears to be reddish or have red-colored areas). […] A major problem with MRSA (and occasionally other staph infections) is that occasionally the skin infection can spread to almost any other organ in the body. When this happens, it is a deep or invasive infection that can spread to the blood and infect internal organs. MRSA infections can cause complications such as infection of heart valves (endocarditis), gangrene or death of the soft tissues (necrotizing fasciitis), and bone or joint infections (osteomyelitis or septic arthritis). This can be deadly. Fever, chills, low blood pressure, joint pains, severe headaches, shortness of breath, and sunburn-like rash over most of the body are symptoms of sepsis (blood poisoning). This requires emergency medical attention.

    https://www.drugs.com/health-guide/mrsa-skin-infection.html
    In cellulitis, the affected skin feels warm and is usually red, swollen, and painful. The redness can be slight or can stand out dramatically compared to the surrounding skin. The area of warmth can be felt with the back of the hand, especially when compared to surrounding skin. There may be a spreading network of red streaks in the skin, caused by infection in the vessels that carry lymph (tissue fluid), as well as enlarged lymph nodes (swollen glands) near the area of infection. […] If you have blisters or pus on the surface of your skin rash, the cellulitis is more likely to be caused by MRSA. […] Fever and a general feeling of sickness (malaise) often accompany cellulitis. Severe infections can cause abnormally low blood pressure if bacteria get into the bloodstream. […] In most cases, skin infections begin to improve within 24 to 48 hours after starting appropriate treatment. Very rarely, the infection may involve tissues below the skin. These deeper infections can be extremely serious and require intensive in-hospital treatment.
