Zespół oddechowy bliskiego wschodu (mers)
Charakterystyka, pielęgnacja i opieka

Zespół oddechowy Bliskiego Wschodu (MERS) wywoływany przez koronawirusa MERS-CoV charakteryzuje się wysoką śmiertelnością na poziomie około 35%. Klinicznie przebieg zakażenia jest zróżnicowany – od bezobjawowego do ciężkiego zapalenia płuc, niewydolności oddechowej, wstrząsu septycznego i niewydolności wielonarządowej. Typowe objawy to gorączka, kaszel i duszność, a także objawy żołądkowo-jelitowe, np. biegunka. Diagnostyka opiera się na testach molekularnych RT-PCR oraz obrazowaniu radiologicznym klatki piersiowej. Czynniki ryzyka ciężkiego przebiegu to wiek >65 lat (OR 4,8, 95% CI: 2,6-8,7) oraz choroby współistniejące (OR 2,7, 95% CI: 1,3-5,7). Personel medyczny stanowi około 25% zakażonych w środowisku szpitalnym, z niższą śmiertelnością (~2%) niż ogólna populacja chorych (36%).

Wprowadzenie do Zespołu Oddechowego Bliskiego Wschodu

Zespół oddechowy bliskiego wschodu (MERS) jest ostrą chorobą wirusową układu oddechowego wywoływaną przez koronawirusa MERS-CoV (Middle East respiratory syndrome coronavirus). Choroba została po raz pierwszy zidentyfikowana w Arabii Saudyjskiej w 2012 roku.12 MERS charakteryzuje się wysoką śmiertelnością, która według danych wynosi około 35% przypadków.34 Większość osób z potwierdzonym zakażeniem MERS-CoV rozwinęła ciężką chorobę układu oddechowego, która w wielu przypadkach prowadziła do zapalenia płuc, niewydolności nerek i innych powikłań.56

Zakażenia MERS-CoV często wiążą się z szerzeniem się wirusa w placówkach opieki zdrowotnej, zarówno wśród personelu, jak i pacjentów. Wykazano, że znaczny odsetek przypadków MERS był związany ze środowiskiem opieki zdrowotnej – od 49% podczas ogniska zakażeń w Dżuddzie i Arabii Saudyjskiej w 2014 roku do 100% podczas ogniska w Al-Hasa, Arabii Saudyjskiej w 2013 r. i wybuchu epidemii w Korei Południowej w 2015 r.7

Objawy kliniczne i diagnostyka MERS

Objawy kliniczne zakażenia MERS-CoV są zróżnicowane, od infekcji bezobjawowej po ciężkie zapalenie płuc, niewydolność oddechową, wstrząs septyczny i niewydolność wielonarządową prowadzącą do śmierci.8 Większość pacjentów hospitalizowanych z powodu MERS-CoV miała wcześniej istniejące schorzenia, takie jak cukrzyca, nadciśnienie, przewlekłe choroby serca i przewlekłe choroby nerek lub immunosupresję, chociaż zakażenia MERS-CoV obserwowano również u wcześniej zdrowych osób.9

Typowe objawy MERS obejmują gorączkę, kaszel i duszność. Zapalenie płuc jest częste, ale pacjenci z MERS nie zawsze rozwijają ten stan. Zgłaszano również objawy żołądkowo-jelitowe, w tym biegunkę.10 Ciężka choroba może powodować niewydolność oddechową wymagającą wentylacji mechanicznej lub wsparcia na oddziale intensywnej terapii. Osoby starsze, osoby z osłabionym układem odpornościowym oraz osoby z przewlekłymi chorobami, takimi jak choroby nerek, nowotwory, przewlekłe choroby płuc, nadciśnienie, choroby układu krążenia i cukrzyca, wydają się być narażone na większe ryzyko rozwoju ciężkiej choroby.11

W diagnostyce MERS-CoV kluczową rolę odgrywa wykrywanie wirusa za pomocą testów molekularnych, w szczególności real-time RT-PCR (reverse transcriptase polymerase chain reaction).12 Badania diagnostyczne obejmują również badanie RTG klatki piersiowej w celu oceny zajęcia płuc.13

Opieka pielęgniarska i postępowanie medyczne w MERS

Obecnie nie ma zatwierdzonego specyficznego leczenia przeciwwirusowego ani szczepionki dla MERS-CoV.1415 Opieka medyczna koncentruje się głównie na leczeniu objawowym i wspomagającym, które ma na celu złagodzenie objawów podczas walki organizmu z infekcją.1617

Ocena pacjenta z podejrzeniem MERS

Ocena pielęgniarska pacjenta z MERS-CoV powinna obejmować:18

  • Szczegółowy wywiad dotyczący podróży do krajów Bliskiego Wschodu lub kontaktu z osobami zakażonymi
  • Monitorowanie parametrów życiowych: temperatury, tętna, ciśnienia, częstości oddechów
  • Ocenę stanu układu oddechowego: obecność kaszlu, duszności, saturacji
  • Ocenę funkcji nerek i innych narządów
  • Identyfikację czynników ryzyka ciężkiego przebiegu choroby (wiek powyżej 65 lat, choroby współistniejące)

1920

Leczenie i opieka wspomagająca

Podstawowe elementy leczenia wspomagającego w MERS obejmują:21

  • Odpoczynek w łóżku
  • Leki przeciwbólowe i przeciwgorączkowe (paracetamol, ibuprofen)
  • Odpowiednie nawodnienie (często wymaga dożylnego podawania płynów)
  • Tlenoterapię w celu utrzymania prawidłowej saturacji
  • W ciężkich przypadkach – wentylację mechaniczną

2223

W przypadku ciężkiej niewydolności oddechowej może być konieczne zastosowanie inwazyjnej wentylacji mechanicznej, a nawet pozaustrojowej oksygenacji membranowej (ECMO) w najcięższych przypadkach.2425 U pacjentów z niewydolnością nerek może być wymagane stosowanie ciągłej terapii nerkozastępczej.26

W niektórych przypadkach rozważane są eksperymentalne metody leczenia, takie jak osocze ozdrowieńców (zawierające przeciwciała od osób, które wyzdrowiały z choroby) lub przeciwciała monoklonalne.27

Główne cele opieki pielęgniarskiej

Główne cele opieki pielęgniarskiej nad pacjentem z MERS-CoV obejmują:28

  • Utrzymanie drożności dróg oddechowych
  • Poprawa wymiany gazowej i zapobieganie lub leczenie hipoksemii
  • Zapobieganie dalszemu rozprzestrzenianiu się zakażenia
  • Łagodzenie objawów i zapewnienie komfortu
  • Monitorowanie i zarządzanie powikłaniami
  • Wsparcie psychologiczne pacjenta

Kontrola i zapobieganie zakażeniom MERS-CoV

Zapobieganie zakażeniom MERS-CoV w placówkach opieki zdrowotnej jest kluczowe ze względu na potencjał wirusa do wywoływania ognisk szpitalnych.29 Efektywne środki zapobiegania i kontroli zakażeń obejmują:

Środki ochrony indywidualnej

Personel medyczny powinien stosować odpowiednie środki ochrony indywidualnej (ŚOI) podczas opieki nad pacjentami z podejrzeniem lub potwierdzonym MERS-CoV:3031

Izolacja pacjentów

Pacjent z podejrzeniem lub potwierdzonym zakażeniem MERS-CoV powinien być umieszczony w:3233

  • Jednoosobowej sali z podciśnieniem (AIIR – airborne infection isolation room)
  • Z wyznaczoną toaletą
  • Z kontrolowanym dostępem personelu medycznego

Jeśli sala z podciśnieniem nie jest dostępna, pacjent powinien być umieszczony w pojedynczej sali z zamkniętymi drzwiami, a podczas transportu powinien nosić maskę chirurgiczną.34

Środki administracyjne i środowiskowe

Kluczowe działania administracyjne obejmują:3536

  • Wdrożenie polityk i procedur mających na celu minimalizację narażenia na patogeny układu oddechowego
  • Szkolenie personelu w zakresie zapobiegania zakażeniom
  • Monitorowanie pracowników opiekujących się pacjentami z MERS-CoV
  • Zapewnienie konsekwentnego stosowania procedur czyszczenia i dezynfekcji
  • Wdrożenie mechanizmów szybkiego alertowania kluczowego personelu placówki o podejrzanych lub potwierdzonych przypadkach MERS-CoV

W przypadku personelu medycznego, który miał niezabezpieczony kontakt z pacjentem z MERS-CoV, zaleca się monitorowanie objawów i powstrzymanie się od pracy w przypadku wystąpienia jakichkolwiek objawów ze strony układu oddechowego.37

Wytyczne dotyczące opieki domowej i opieki ambulatoryjnej

W przypadku pacjentów z łagodniejszym przebiegiem MERS, którzy nie wymagają hospitalizacji, lub dla rekonwalescentów, istotne są następujące zalecenia:3839

  • Izolacja pacjenta w osobnym pomieszczeniu z dobrą wentylacją
  • Ograniczenie kontaktu z innymi domownikami
  • Noszenie maski przez pacjenta podczas kontaktu z innymi osobami
  • Dokładna i częsta higiena rąk
  • Używanie oddzielnych przedmiotów osobistych i naczyń
  • Częste czyszczenie i dezynfekcja powierzchni

Osoby opiekujące się pacjentem z MERS w warunkach domowych powinny nosić maskę, fartuch i rękawiczki, jeśli mają kontakt z płynami ustrojowymi lub wydzielinami chorego.40

Szczególne sytuacje kliniczne w opiece nad pacjentem z MERS

MERS u kobiet w ciąży

Ciąża może zwiększać ryzyko ciężkiego przebiegu zakażeń wirusowych układu oddechowego, w tym MERS-CoV.41 Dane dotyczące wpływu MERS-CoV na przebieg ciąży są ograniczone, ale opisano przypadki pomyślnego zakończenia ciąży pomimo ciężkiego przebiegu zakażenia u matki.42 Kobiety w ciąży z MERS-CoV wymagają szczególnej opieki multidyscyplinarnej i ścisłego monitorowania zarówno stanu matki, jak i płodu.43

Pacjenci z grupy podwyższonego ryzyka

Niektóre grupy pacjentów są szczególnie narażone na ciężki przebieg MERS-CoV i wymagają specjalnej uwagi:4445

  • Osoby powyżej 65 roku życia
  • Pacjenci z osłabionym układem odpornościowym
  • Osoby z chorobami przewlekłymi (cukrzyca, choroby nerek, choroby płuc, choroby serca)

Analiza wieloczynnikowa wykazała, że wiek powyżej 65 lat (OR 4,8, 95% CI: 2,6-8,7) i obecność chorób współistniejących (OR: 2,7, 95% CI: 1,3-5,7) były związane ze zwiększoną śmiertelnością, podczas gdy praca jako personel medyczny miała działanie ochronne (OR 0,07, 95% CI: 0,01-0,34).4647

Personel medyczny z zakażeniem MERS-CoV

Personel medyczny stanowi szczególną grupę narażoną na zakażenie MERS-CoV. Badania wykazały, że około 25% (n=105/422) przypadków MERS, które nabyły zakażenie w warunkach szpitalnych, dotyczył personelu medycznego.48 Pracownicy ochrony zdrowia zakażeni MERS-CoV mieli jednak lepsze rokowanie niż inni pacjenci – wskaźnik śmiertelności wśród personelu medycznego wynosił około 2%, w porównaniu do 36% wśród innych pacjentów.49

Badanie wieloośrodkowe wykazało, że około 10% krytycznie chorych pacjentów z MERS stanowił personel medyczny. Śmiertelność wśród krytycznie chorych pracowników ochrony zdrowia z MERS była znacząca (25%), ale niższa niż w ogólnej populacji pacjentów z MERS wymagających intensywnej terapii.50

Personel medyczny zakażony MERS często doświadcza odległych konsekwencji choroby, zarówno fizycznych, jak i emocjonalnych, które powinny być systematycznie oceniane i odpowiednio wcześnie leczone przez instytucje opieki zdrowotnej.51

Organizacja opieki podczas ogniska MERS w szpitalu

W przypadku wystąpienia ogniska MERS w placówce ochrony zdrowia, konieczne jest wdrożenie kompleksowych działań organizacyjnych:5253

  • Zwiększenie liczby sal z podciśnieniem przeznaczonych dla pacjentów z MERS
  • Zapewnienie odpowiedniego stosunku personelu do pacjentów (zazwyczaj 1:1, a w przypadku pacjentów na ECMO 2:1)
  • Intensyfikacja praktyk zapobiegania zakażeniom
  • Wykonywanie procedur generujących aerozol (np. intubacja) przez najbardziej doświadczony dostępny personel z zachowaniem środków ostrożności
  • Integracja funkcji oddziału intensywnej terapii z ogólnoszpitalnymi planami
  • Zarządzanie personelem i narażeniem personelu

W niektórych przypadkach konieczne może być czasowe zamknięcie placówki, aby zapobiec dalszemu rozprzestrzenianiu się zakażenia.54

Edukacja i szkolenia personelu medycznego

Edukacja i szkolenie personelu medycznego są kluczowymi elementami zapobiegania zakażeniom MERS-CoV:5556

  • Cały personel powinien przejść szkolenie dotyczące zapobiegania i kontroli zakażeń MERS-CoV
  • Szkolenia powinny obejmować rozpoznawanie objawów MERS, odpowiednie stosowanie ŚOI, procedury izolacji pacjentów
  • Personel powinien być świadomy ryzyka zawodowego i procedur postępowania po ekspozycji
  • Szkolenia powinny być regularnie odświeżane

Ważne jest, aby wszyscy pracownicy z przewidywanym narażeniem zawodowym na MERS-CoV byli przeszkoleni w zakresie źródeł narażenia na MERS-CoV, zagrożeń związanych z tym narażeniem oraz odpowiednich protokołów w miejscu pracy, aby zapobiec lub zmniejszyć prawdopodobieństwo narażenia.57

Wytyczne dotyczące transportu i postępowania ze zmarłymi

Ciało osoby zmarłej na MERS jest wysoce zakaźne i wymaga specjalnego postępowania:58

  • Zwłoki powinny być hermetycznie zamknięte
  • Należy przeprowadzić dezynfekcję ciała
  • Transport powinien odbywać się z zachowaniem środków minimalizujących ryzyko transmisji
  • Personel zajmujący się zwłokami powinien stosować pełne środki ochrony indywidualnej

Podsumowanie zasad opieki nad pacjentem z MERS

Opieka nad pacjentem z MERS-CoV wymaga kompleksowego podejścia, które obejmuje:5960

  • Wczesne rozpoznanie i izolację pacjentów z podejrzeniem MERS
  • Stosowanie odpowiednich środków ochrony indywidualnej przez personel
  • Leczenie wspomagające ukierunkowane na objawy i powikłania
  • Ścisłe monitorowanie parametrów życiowych i funkcji narządów
  • W ciężkich przypadkach – zaawansowane techniki podtrzymywania życia (wentylacja mechaniczna, ECMO, terapia nerkozastępcza)
  • Zapobieganie transmisji szpitalnej poprzez rygorystyczne przestrzeganie zasad kontroli zakażeń
  • Edukację personelu i odpowiednią organizację opieki

Skuteczne zarządzanie ogniskami MERS-CoV wymaga integracji funkcji oddziału intensywnej terapii z ogólnoszpitalnymi planami, posiadania planów gotowości, wdrażania odpowiednich praktyk kontroli zakażeń oraz zarządzania personelem i narażeniem personelu.60

Choć MERS nadal stanowi poważne zagrożenie dla zdrowia publicznego, szczególnie w placówkach opieki zdrowotnej, prawidłowe stosowanie środków zapobiegania i kontroli zakażeń, szybka diagnostyka oraz odpowiednie leczenie wspomagające mogą znacząco ograniczyć rozprzestrzenianie się wirusa i poprawić rokowanie pacjentów.

    Middle East respiratory syndrome (MERS) was first recognised in Saudi Arabia in 2012. It is caused by infection with Middle East respiratory syndrome coronavirus (MERS-CoV). […] MERS-CoV mainly causes a respiratory infection, which can range from mild illness, to severe pneumonia. Older persons and those with diabetes or immunosuppression are at higher risk of severe illness. Symptoms of MERS may include: fever, cough, breathing difficulties, muscles aches, diarrhoea, nausea and vomiting. […] There is no specific treatment for MERS. […] You can protect yourself from MERS while living or travelling in affected areas by: avoiding close contact with camels, washing hands regularly and taking particular care when visiting places where animals are present, avoiding close contact with people who are unwell, avoiding consuming raw, undercooked or unpasteurised camel products, including meat, urine and milk. […] There is no vaccine available to prevent MERS.

    Middle East Respiratory Syndrome (MERS) is an acute viral respiratory illness with high mortality caused by a new strain of betacoronavirus (MERS-CoV). […] Therefore, to eliminate the spread of MERS-CoV, infection prevention and control measures should be implemented with rigor. […] To ensure efficient MERS-CoV infection prevention and control, care should be taken to provide comprehensive infection control measures including contact control, hand hygiene, personal protective equipment, disinfection, and environmental cleaning. […] The MERS outbreak in South Korea occurred in hospital settings through contacts with infected outpatients and inpatients. […] Therefore, the most important measure for infection prevention and control of MERS-CoV is blocking the transmission through early diagnosis of suspected or confirmed patients and their intra-hospital isolation.

  • #7 Health Care Associated Middle East Respiratory Syndrome (MERS): A Case from Iran
    https://pmc.ncbi.nlm.nih.gov/articles/PMC4841994/
    A significant fraction of MERS cases were linked to the healthcare setting, ranging from 49% for the nosocomial outbreak in Jeddah and Saudi Arabia in 2014 to 100 % for both the outbreak in Al-Hasa, Saudi Arabia, in 2013 and the recent outbreak in South Korea in 2015. […] Infection in the healthcare setting is an important risk factor for human-to-human transmission and close and prolonged contact with the index case seems to be a necessity for the disease transmission. […] Thus, Infection in the healthcare setting is an important risk factor for person to-person transmission. It is not easy to recognize patients with MERS-CoV during the early stages of the disease based on clinical presentations alone. Thus, enhanced infection control practices in medical facilities should be attempted to protect those at risk of MERS.

    In 2015, South Korea experienced an outbreak of Middle East respiratory syndrome (MERS), and our hospital experienced a nosocomial MERS infection. […] Our study provide compelling evidence that routine infection-prevention policies can greatly reduce nosocomial transmission of MERS. […] Routine examination with chest X-ray in the ED showed suspicious pneumonic consolidation in the left lower lobe. […] After confirmation of MERS infection in the index patient, we could not identify those who had never had contact with the index patient or the virus-contaminated environment in the ED because of the frequencies of their movements within and around the ED and crowding. […] To protect against further transmissions by infected patients, we closed the hospital over 1month. […] Our study confirmed the importance of a routine basic infection policy for blocking widespread propagation of nosocomial MERS infection. […] Routine infection-prevention practices, such as wearing a surgical mask and hand hygiene, can reduce the risk of nosocomial infection. […] Routine infection-prevention policies should be established in all medical institutions during a MERS outbreak.

    No vaccine or specific treatment are currently available, however several MERS-CoV specific vaccines and treatments are in clinical development. In the absence of MERS-specific therapeutics, treatment of MERS patients is supportive and based on the patients clinical condition. […] Transmission of MERS-CoV has occurred in health care facilities in several Member States, including from patients to health care workers and between patients in a health care setting before MERS-CoV was diagnosed. However, it is not always possible to identify patients with MERSCoV early or without testing because symptoms and other clinical features may be nonspecific. […] Infection prevention and control measures are therefore critical to prevent the possible spread of MERSCoV in health care facilities. Facilities that provide care for patients suspected or confirmed MERSCoV infection should take appropriate measures to decrease the risk of transmission of the virus from an infected patient to other patients, health care workers, or visitors. Health care workers should be educated and trained in infection prevention and control and should refresh these skills regularly.

    Middle East Respiratory Syndrome Coronavirus (MERS-CoV) leads to healthcare-associated transmission to patients and healthcare workers with potentially fatal outcomes. […] We aimed to describe the clinical course and functional outcomes of critically ill healthcare workers (HCWs) with MERS. […] Approximately 10% of critically ill patients with MERS were HCWs. Hospital mortality rate was substantial (25%). Patients with chronic renal impairment represented a particularly high-risk group that should receive extra caution during suspected or confirmed MERS cases clinical care assignment and during outbreaks. Long-term repercussions of critical illness due to MERS on HCWs in particular, and patients in general, remain unknown and should be investigated in larger studies. […] Our study demonstrates that hospital mortality among critically ill HCWs with MERS was substantial [25% (8/32)], but lower than what has been reported in general ICU MERS patients.

    The noted increased use of ECMO in non-surviving HCW is probably reflective of the severity of respiratory failure where ECMO is used as a rescue therapy. […] Eleven (11/13) of the responding HCWs thought that MERS-CoV infection could have been avoided had they complied with infection control precautions and wearing personal protective equipment. […] In conclusion, this is the largest cohort of critically ill HCWs with MERS to date. The lower mortality rates, younger age and fewer comorbidities in comparison to the general population are highlighted in this study. Nevertheless, MERS related mortality in HCWs remained substantial, particularly in HCWs with chronic renal impairment. This sheds a new light on a specifically high-risk group that should be offered special attention especially during clinical care assignment to suspected or confirmed MERS cases. Additionally, the often overlooked residual physical and emotional negative outcomes need to be systematically assessed and addressed in a timely manner by health care institutions.

    In 2015, South Korea experienced an outbreak of Middle East respiratory syndrome (MERS), and our hospital experienced a nosocomial MERS infection. […] Our study provide compelling evidence that routine infection-prevention policies can greatly reduce nosocomial transmission of MERS. […] Routine examination with chest X-ray in the ED showed suspicious pneumonic consolidation in the left lower lobe. […] After confirmation of MERS infection in the index patient, we could not identify those who had never had contact with the index patient or the virus-contaminated environment in the ED because of the frequencies of their movements within and around the ED and crowding. […] To protect against further transmissions by infected patients, we closed the hospital over 1month. […] Our study confirmed the importance of a routine basic infection policy for blocking widespread propagation of nosocomial MERS infection. […] Routine infection-prevention practices, such as wearing a surgical mask and hand hygiene, can reduce the risk of nosocomial infection. […] Routine infection-prevention policies should be established in all medical institutions during a MERS outbreak.

    Protect workers from exposure when tasked with cleaning surfaces and equipment potentially contaminated with MERS-CoV. […] Select and provide workers with appropriate PPE to prevent exposure to MERS-CoV, blood or body fluids that may contain MERS-CoV, and other sources of infectious material. […] Worker protection from exposure to infectious agents, including MERS-CoV, is necessary when work tasks involve handling, treatment, transport, and disposal of medical, laboratory and other potentially contaminated waste. […] Ensure that supervisors and all potentially exposed workers are aware of the symptoms of MERS. […] Train all workers with reasonably anticipated occupational exposure to MERS (as described in this document) about the sources of MERS-CoV exposure, the hazards associated with that exposure, and appropriate workplace protocols in place to prevent or reduce the likelihood of exposure.

    Infection prevention and control measures should be implemented systematically based on the standard, contact, and droplet precautions. […] All employees should abide by infection prevention/control rules and receive training regarding MERS-CoV infection. […] The body of a deceased MERS patient is highly infectious, and the corpse should be hermetically sealed, disinfected, and transported to minimize the transmission risk.

    Infection prevention practices were intensified. […] The ICU response required careful facility and staff management and proper infection control and prevention practices. […] The medical management of MERS patients was largely supportive. […] Most (80.9 %) MERS patients required endotracheal intubation, which was performed by the most experienced available physician with airborne precautions. […] The care for MERS patients was demanding. […] During the outbreak, the nurse-to-patient ratio was mostly 1:1 except for one patient on ECMO (2:1). […] The exposure risk to MERS-CoV can exert significant psychosocial stress on HCWs. […] MERS management was supportive and largely adhered to the WHO recommendations.

    Middle East Respiratory Syndrome (MERS) is an acute viral respiratory illness with high mortality caused by a new strain of betacoronavirus (MERS-CoV). […] Therefore, to eliminate the spread of MERS-CoV, infection prevention and control measures should be implemented with rigor. […] To ensure efficient MERS-CoV infection prevention and control, care should be taken to provide comprehensive infection control measures including contact control, hand hygiene, personal protective equipment, disinfection, and environmental cleaning. […] The MERS outbreak in South Korea occurred in hospital settings through contacts with infected outpatients and inpatients. […] Therefore, the most important measure for infection prevention and control of MERS-CoV is blocking the transmission through early diagnosis of suspected or confirmed patients and their intra-hospital isolation.
