Ostra zespół niewydolności oddechowej
Leczenie

Ostry zespół niewydolności oddechowej (SARS) wywołany przez koronawirusa SARS-CoV charakteryzuje się ciężkim przebiegiem klinicznym, wymagającym głównie leczenia objawowego i podtrzymującego. W terapii stosuje się dożylne nawodnienie, tlenoterapię oraz leczenie powikłań, a w przypadkach ostrej niewydolności oddechowej – nieinwazyjną wentylację ciśnieniową (NIPPV), wentylację mechaniczną z objętościami oddechowymi około 6 ml/kg masy ciała idealnej i ciśnieniem plateau <30 cm H₂O, pozycjonowanie na brzuchu oraz ECMO. Leki przeciwwirusowe, takie jak rybawiryna, lopinawir/rytonawir (LPV/r) i remdesiwir, były testowane, jednak rybawiryna wykazuje ograniczoną skuteczność i istotną toksyczność (np. anemia z obniżeniem hemoglobiny o ≥2 g/dl u 49% pacjentów), natomiast LPV/r i remdesiwir wykazują potencjalne korzyści, choć wymagają dalszych badań. Immunomodulacja obejmuje stosowanie kortykosteroidów, interferonów alfa-1 oraz tocilizumabu, jednak ich efektywność i bezpieczeństwo pozostają nie do końca potwierdzone, a stosowanie kortykosteroidów wiąże się z ryzykiem nasilenia replikacji wirusa i poważnych działań niepożądanych.

Leczenie ostrego zespołu niewydolności oddechowej (SARS)

Ostra zespół niewydolności oddechowej (SARS) to ciężka, zagrażająca życiu choroba układu oddechowego wywoływana przez koronawirusa SARS-CoV. Mimo intensywnych badań prowadzonych od czasu wybuchu epidemii w latach 2002-2003, nie opracowano dotychczas jednoznacznie skutecznej terapii przeciwko SARS. Leczenie w dużej mierze opiera się na postępowaniu objawowym i podtrzymującym, podczas gdy organizm pacjenta zwalcza infekcję wirusową.12

Leczenie objawowe i podtrzymujące

Podstawą terapii SARS jest leczenie objawowe, które ma na celu łagodzenie objawów i utrzymanie podstawowych funkcji życiowych pacjenta, podczas gdy jego układ odpornościowy zwalcza wirusa.1 W przypadku pacjentów z łagodnymi objawami leczenie może obejmować leki przeciwbólowe i przeciwgorączkowe, podobnie jak w przypadku przeziębienia czy grypy.23 Pacjenci z cięższym przebiegiem choroby często wymagają hospitalizacji. Postępowanie terapeutyczne może wtedy obejmować:4

  • Podawanie płynów dożylnie dla utrzymania odpowiedniego nawodnienia15
  • Tlenoterapię w przypadku obniżonej saturacji6
  • Leczenie powikłań, takich jak wtórne zakażenia bakteryjne4

Wsparcie oddechowe

W ciężkich przypadkach SARS, gdy pacjenci rozwijają ostrą niewydolność oddechową, konieczne może być zastosowanie zaawansowanych metod wspomagania oddychania:7

  • Nieinwazyjna wentylacja ciśnieniem dodatnim (NIPPV) – forma wsparcia wentylacyjnego przez szczelnie dopasowaną maskę twarzową lub nosową, często stosowana w połączeniu z ciągłym dodatnim ciśnieniem w drogach oddechowych lub dwupoziomowym dodatnim ciśnieniem w drogach oddechowych u pacjentów z zagrażającą niewydolnością oddechową.8 Badania wykazały, że NIPPV może być skutecznym leczeniem dla pacjentów z SARS z niewydolnością oddechową, jeśli jest stosowana z odpowiednią ostrożnością i w odpowiednim środowisku.9
  • Wentylacja mechaniczna – około 10-20% pacjentów z SARS wymaga intubacji i mechanicznego wspomagania oddychania.72 W takich przypadkach zaleca się strategię wentylacji ochronnej płuc z niskimi objętościami oddechowymi (około 6 ml na kg idealnej masy ciała) i utrzymywanie ciśnienia plateau poniżej 30 cm H₂O.10
  • Pozycja na brzuchu (prone positioning) – u pacjentów z ciężkim SARS i ARDS stosuje się układanie pacjenta w pozycji na brzuchu, co może poprawić natlenowanie.11
  • Pozaustrojowe natlenianie krwi (ECMO) – w najbardziej opornych przypadkach hipoksemii, gdy standardowa wentylacja nie przynosi efektów.11

Leki stosowane w terapii SARS

Leki przeciwwirusowe

Podczas epidemii SARS testowano różne leki przeciwwirusowe, jednak ich skuteczność pozostaje dyskusyjna:12

  • Rybawiryna – nukleozydowy analog guanozyny o szerokim spektrum działania przeciwwirusowego. Była szeroko stosowana podczas epidemii SARS, jednak jej skuteczność została zakwestionowana. Ponad 90% pacjentów w Hongkongu otrzymało rybawirynę, ale późniejsze analizy nie wykazały jednoznacznej korzyści klinicznej.1213 Lek ten wiąże się z istotnymi działaniami niepożądanymi, w tym anemią (spadek hemoglobiny o 2 g/dl lub więcej u 49% pacjentów).14 Obecnie nie zaleca się stosowania rybawiryny ze względu na brak skuteczności i toksyczność, mogącą prowadzić do anemii hemolitycznej i zaburzeń elektrolitowych.15
  • Lopinawir/rytonawir (LPV/r) – połączenie inhibitorów proteazy HIV, które w badaniach laboratoryjnych wykazało działanie hamujące wobec proteazy 3CL SARS-CoV, istotnej dla cyklu życiowego wirusa.14 W retrospektywnym badaniu kohortowym pacjentów z SARS w Hongkongu, terapia początkowa z użyciem LPV/r w połączeniu z rybawiryną znacząco zmniejszyła śmiertelność w 21. dniu w porównaniu z samą rybawirynę i kortykosteroidami.16 Zaobserwowano również zmniejszenie częstości intubacji i niekorzystnych wyników klinicznych przy zastosowaniu tej kombinacji leków.14
  • Remdesiwir – lek przeciwwirusowy początkowo opracowany przeciwko wirusowi Ebola, który w późniejszych badaniach wykazał skuteczność przeciwko koronawirusom. Hamuje on polimerazę RNA zależną od RNA (RdRp), wykazując szerokie spektrum działania przeciwwirusowego przeciwko wirusom RNA, w tym SARS-CoV.17 Europejska Agencja Leków pozytywnie rekomenduje remdesiwir w leczeniu zakażeń koronawirusowych.18 Istnieją sugestie, że leki przeciwwirusowe opracowane dla COVID-19, takie jak remdesiwir i kombinacja nirmatrelvir/ritonavir (Paxlovid), mogłyby być również skuteczne przeciwko SARS-CoV.1920

Leki immunomodulujące

Podczas epidemii SARS stosowano również leki wpływające na układ odpornościowy, mające na celu ograniczenie nadmiernej reakcji immunologicznej potencjalnie odpowiedzialnej za ciężki przebieg choroby:14

  • Kortykosteroidy – były szeroko stosowane w leczeniu SARS, szczególnie w przypadkach ciężkiego zapalenia płuc. Wykazały skuteczność w obniżaniu gorączki i odwracaniu zmian widocznych w badaniach radiograficznych klatki piersiowej.21 Jednakże stosowanie kortykosteroidów wiąże się z ryzykiem nasilenia replikacji wirusa poprzez tłumienie wrodzonej odpowiedzi immunologicznej.14 Ponadto, stosowanie kortykosteroidów w dużych dawkach i przez dłuższy czas wiązało się z istotnymi działaniami niepożądanymi, takimi jak martwica jałowa kości i psychoza indukowana steroidami.2223 Skuteczność kortykosteroidów w leczeniu SARS została zasugerowana jedynie na podstawie niekontrolowanych obserwacji, a ich rola w terapii wymaga potwierdzenia w randomizowanych badaniach kontrolowanych.21
  • Interferony (IFN) – znane są jako ważne glikoproteiny, które mogą hamować replikację wirusów. W badaniu otwartym obejmującym 22 pacjentów z SARS, doustny prednizon 50 mg lub dożylny metyloprednizolon 40 mg podawano co 12 godzin. IFN alfa-1 podawano w dawce rosnącej od 9 μg/dzień do 15 μg/dzień przez 2-10 dni leczenia. Połączenie IFN alfa-1 i kortykosteroidu znacząco zmniejszyło zaburzenia saturacji tlenu i poziomy kinazy kreatynowej związane z chorobą w porównaniu z samym kortykosteroidem.24
  • Tocilizumab – lek immunosupresyjny stosowany w leczeniu reumatoidalnego zapalenia stawów, który stał się obiecującym kandydatem w leczeniu ciężkich przypadków zakażeń koronawirusami.25 Jego działanie polega na blokowaniu receptora dla interleukiny-6, co może pomóc w ograniczeniu „burzy cytokinowej” – nadmiernej reakcji immunologicznej obserwowanej w ciężkich przypadkach SARS.26

Osocze ozdrowieńców i immunoglobuliny

W przypadkach, gdy pacjenci nie odpowiadali na standardowe leczenie rybawiryną i kortykosteroidami, stosowano terapię ratunkową z użyciem osocza ozdrowieńców i immunoglobulin:27

  • Osocze ozdrowieńców – pozyskiwane od pacjentów, którzy wyzdrowieli z SARS, było stosowane jako ostateczna forma leczenia.27 Osocze zawiera przeciwciała, które mogą pomóc w neutralizacji wirusa. Metaanaliza 32 badań wykazała, że osocze ozdrowieńców może zmniejszyć śmiertelność wśród pacjentów z zakażeniami koronawirusowymi i ciężką grypą.25 W ciężkich przypadkach SARS, płynna część krwi od osób, które już wyzdrowiały z SARS, była podawana jako forma leczenia.4
  • Immunoglobuliny dożylne (IVIG) – ludzkie immunoglobuliny były stosowane u wybranych pacjentów z SARS, którzy nadal pogarszali się mimo leczenia.28 Jednak dane dotyczące skuteczności IVIG w leczeniu SARS są niejednoznaczne.23

Leczenie skojarzone i protokoły terapeutyczne

W praktyce klinicznej podczas epidemii SARS stosowano różne protokoły leczenia skojarzonego, często łącząc leki przeciwwirusowe, kortykosteroidy i antybiotyki:13

W prospektywnym badaniu kohortowym populacji Hongkongu, początkowym pacjentom z SARS podawano antybiotyki na zapalenie płuc i oseltamiwir na grypę. Jeśli gorączka utrzymywała się po 2 dniach od hospitalizacji, pacjentom podawano rybawirynę w połączeniu z małą dawką prednizolonu lub hydrokortyzonu. Wysokie dawki metyloprednizolonu przez 3 kolejne dni do 6 dawek podawano po 3-4 dniach, jeśli gorączka utrzymywała się lub cień płucny się powiększał. Rybawirynę i małą dawkę kortykosteroidu podawano nieprzerwanie przez maksymalnie 12 dni, aż do ustąpienia zmian w płucach.13

Połączenie antybiotyków o szerokim spektrum działania, rybawiryny i kortykosteroidów było również stosowane do leczenia pacjentów w innych badaniach obserwacyjnych.13 Większość klinicystów stosuje protokoły kliniczne podobne do tych stosowanych w pozaszpitalnym zapaleniu płuc przy leczeniu podejrzewanego lub prawdopodobnego przypadku SARS. Stosowane są antybiotyki o szerokim spektrum działania, w tym fluorochinolon lub makrolid.15

Na podstawie doświadczeń z epidemii SARS opracowano standardowy protokół leczenia, obejmujący początkowo wysokie (ale nie pulsacyjne) dawki metyloprednizolonu ze stopniowym zmniejszaniem przez trzy tygodnie.29

Tradycyjna medycyna chińska

Tradycyjna medycyna chińska (TCM) była stosowana jednocześnie z innymi lekami w leczeniu SARS w Chinach kontynentalnych, z dobrymi wynikami.30 Doświadczenia z tradycyjną medycyną chińską są obiecujące, a jej stosowanie jako terapii uzupełniającej powinno być dalej badane.21 Substancje takie jak papainopodobna proteaza (PLpro), proteaza podobna do 3C (3CLpro) i inne alternatywne leki terapeutyczne są przedmiotem aktywnych badań.31

Skuteczność leczenia ziołowego w kontrolowaniu chorób zakaźnych została szeroko opisana w 2003 roku podczas epidemii zespołu ostrej niewydolności oddechowej (SARS). Obecność silnych właściwości przeciwwirusowych w różnych roślinach może być bardzo ważna w chorobach wirusowych, zwłaszcza w przypadku SARS.32

Kontrola zakażeń i izolacja

Kluczowym elementem postępowania w przypadku SARS jest kontrola zakażeń, mająca na celu zapobieganie rozprzestrzenianiu się wirusa:33

  • Pacjenci z podejrzeniem SARS powinni być natychmiast izolowani, najlepiej w pomieszczeniach z ujemnym ciśnieniem, aby ograniczyć rozprzestrzenianie się mikroorganizmów w powietrzu.2634
  • Personel medyczny powinien stosować pełne środki ochrony osobistej, w tym maski (najlepiej N95 lub o wyższej skuteczności filtracji), gogle, fartuchy i rękawiczki podczas kontaktu z pacjentami z SARS.197
  • W niektórych przypadkach naturalna wentylacja poprzez otwieranie drzwi i okien może pomóc w zmniejszeniu stężenia cząstek wirusa w pomieszczeniu.26
  • Odwiedzający pacjentów z SARS również powinni stosować odpowiednie środki ochrony osobistej.33

Proces wykorzystujący kryteria kliniczne i epidemiologiczne powinien być stosowany w celu szybkiego rozpoznania pacjentów z podejrzeniem SARS. Środki kontroli zakażeń obejmują środki ostrożności dotyczące kontaktu (używanie rękawiczek, fartuchów i ochrony oczu), środki ostrożności dotyczące kropelkowe (zapewnienie pacjentowi prywatnego pokoju i ograniczenie jego ruchu) oraz środki ostrożności dotyczące przenoszenia drogą powietrzną (używanie respiratorów N-95 i upewnienie się, że pokój izolacyjny ma środowisko z ujemnym ciśnieniem).35

Wnioski i perspektywy

Optymalne leczenie SARS pozostaje nieuchwytne. Należy przeprowadzić randomizowane kontrolowane badania kliniczne, zwłaszcza poprzez współpracę międzynarodową, aby odkryć najlepszą formę terapii.8 Doświadczenia zebrane podczas epidemii SARS są cenne dla projektowania przyszłych badań i opracowywania skutecznych terapii przeciwko koronawirusom.36

Mimo intensywnych badań, nadal brakuje jednoznacznych dowodów na skuteczność konkretnych leków przeciwko SARS. Wiele potencjalnie obiecujących terapii wymaga dalszych badań, a opracowanie skutecznej szczepionki pozostaje priorytetem.3738

Warto zauważyć, że pandemia COVID-19 doprowadziła do szybkiego rozwoju kilku leków przeciwwirusowych i szczepionek, które mogą być potencjalnie skuteczne również przeciwko SARS-CoV-1. Leki przeciwwirusowe, takie jak inhibitory polimerazy i proteazy przeciwko SARS-CoV-2, prawdopodobnie będą skuteczne przeciwko SARS-CoV-1. Szczepionki przeciwko COVID-19 mogą zapewniać pewien poziom ochrony krzyżowej przeciwko SARS, jednak zakres takiej ochrony wymaga dalszych badań.19

Ważne jest, aby kontynuować badania nad skutecznymi terapiami przeciwko SARS i innym koronawirusom, które mogą stanowić zagrożenie dla zdrowia publicznego w przyszłości.39 Starannie zaprojektowane badania kliniczne są niezbędne do określenia optymalnego czasu i dawkowania wszelkich środków przeciwwirusowych, osocza ozdrowieńców i środków immunomodulujących w leczeniu potencjalnie związanego z odpowiedzią immunologiczną uszkodzenia płuc w SARS i nowo powstałych infekcjach, takich jak zespół oddechowy Bliskiego Wschodu.39

  • #3 SARS (Severe Acute Respiratory Syndrome): Symptoms and Treatment
    https://www.webmd.com/lung/lung-what-is-sars
    At the time of the original outbreak, there were no targeted treatments available for SARS. Antiviral drugs like ribavirin and lopinavir/ritonavir were used. So were corticosteroids (commonly known as steroids). The best treatment strategy for SARS remains unknown. […] People with SARS were mostly given supportive care, such as antibiotics to fight off other infections while they recovered, or steroids to reduce swelling in the lungs. In serious cases, they could be given blood plasma from someone who already recovered from SARS and whose plasma would have antibodies. […] If their symptoms were mild, they recovered at home, taking over-the-counter medications for a fever or muscle aches. But if the symptoms got worse, they may have gone to a hospital for more treatment, like getting fluids or oxygen.

    People who are thought to have SARS should be checked right away by a provider. If they are suspected of having SARS, they should be kept isolated in a hospital. […] Treatment may include: […] Antibiotics to treat bacteria that cause pneumonia (until bacterial pneumonia is ruled out or if there is bacterial pneumonia in addition to SARS) and to treat bacterial infections that could occur in addition to SARS […] Oxygen, breathing support (mechanical ventilation), or chest therapy […] In some serious cases, the liquid part of blood from people who have already recovered from SARS has been given as a treatment. […] There is no strong evidence that these treatments work well. There is evidence that the antiviral medicine, ribavirin, does not work. Newer antivirals have not been tried as the disease has not occurred recently.

    SARS treatment options include: […] There still isnt an effective treatment for SARS coronavirus 1 despite a global effort to develop one. Until an effective treatment is created, your doctor will use advanced care to help ease symptoms and prevent the spread of the virus. […] Antiviral treatments and medications may help prevent severe illness in high-risk patients. […] Corticosteroids: These medications may be given to decrease inflammation in the lungs, which helps with breathing. […] Supportive treatments: Oxygen therapy, hyperbaric oxygen therapy (HBOT), intravenous (IV) fluids and medications to address symptoms like fever and cough. […] Mechanical ventilation: In severe cases where patients struggle to breathe independently, ventilators are used to ensure they receive sufficient oxygen. […] It is important to note, antibiotics do not kill the SARS coronavirus 1 virus.
  • #7 Information Regarding Severe Acute Respiratory Syndrome (SARS) | Occupational Safety and Health Administration
    https://www.osha.gov/emergency-preparedness/sars
    Severe acute respiratory syndrome (SARS) is an emerging, sometimes fatal, respiratory illness. […] Treatment consists of antibiotics and steroids, with other options being explored. […] Between 10 and 20 percent of SARS patients have required ventilator support for a period of time. […] The CDC provides recommendations for those handling human remains of SARS patients. […] Workers handling human remains of SARS patients should use respiratory protection (N95 or higher filter efficiency) and protective garments including surgical scrub suit, surgical cap, impervious gown or apron with full sleeve coverage, eye protection (e.g., goggles or face shield), shoe covers and double surgical gloves with an interposed layer of cut-proof synthetic mesh gloves. […] If an employee experiences a fever and respiratory symptoms after contact with a patient known to be infected with SARS, the CDC recommends that the employee be excluded from duty.
  • #8 Treatment of severe acute respiratory syndrome
    https://pmc.ncbi.nlm.nih.gov/articles/PMC7088345/
    In patients who deteriorated irrevocably despite receiving pulse methylprednisolone, convalescent plasma, obtained from patients who recovered from SARS, had been used as a last resort. […] Noninvasive positive pressure ventilation (NIPPV) is a form of ventilatory support through a tight-fitting facemask or nasal mask frequently administered in combination with continuous positive airway pressure or bi-level positive airway pressure for patients with impending respiratory failure. […] The present therapy of SARS is less than satisfactory, and much effort has been expended in looking for novel treatment modalities. […] The optimal treatment regimen for SARS remains elusive. Randomized controlled treatment trials should be done, especially through international collaboration, to discover the best form of therapy.
  • #9 Management of Critically Ill Patients with Severe Acute Respiratory Syndrome (SARS)
    https://www.medsci.org/v01p0001
    Severe acute respiratory syndrome (SARS) is frequently complicated with acute respiratory failure. In this article, we aim to focus on the management of the subgroup of SARS patients who are critically ill. Most SARS patients would require high flow oxygen supplementation, 20-30% required intensive care unit (ICU) or high dependency care, and 13-26% developed acute respiratory distress syndrome (ARDS). The management of critically ill SARS patients requires timely institution of pharmacotherapy where applicable and supportive treatment (oxygen therapy, noninvasive and invasive ventilation). Superimposed bacterial and other opportunistic infections are common, especially in those treated with mechanical ventilation. Appropriate use of personal protection equipment and adherence to infection control measures is mandatory for effective infection control. […] Much of the knowledge about the clinical aspects of SARS is based on retrospective observational data and randomized-controlled trials are required for confirmation.
  • #10 Lessons from Severe Acute Respiratory Syndrome (SARS) | RT
    https://respiratory-therapy.com/disorders-diseases/critical-care/acute-disorders/lesson-from-sars/
    Principles of infection control and ventilator management taken from the SARS epidemic may serve during future viral outbreaks. […] Twenty-five percent of patients who are diagnosed with SARS develop acute respiratory distress syndrome and will need mechanical ventilation. The ventilatory management of patients with SARS does not differ much from that for patients with ARDS alone. A low tidal volume lung protective strategy should be adopted, with the target tidal volumes at 6 mL per ideal body weight. Plateau pressures are preferably kept less than 30 cm H2O. This is modeled after the recommendations from the National Institutes of Health ARDS Network. Either volume- or pressure-control ventilation can be used. High levels of positive end-expiratory pressure (PEEP) may be used to maintain a PaO2 greater than 55 mm Hg. PEEP helps to increase end-expiratory lung volume, recruits unventilated alveoli, decreases intrapulmonary shunt, and improves V/Q (ventilation perfusion) matching.
  • #11 SARS & MERS Virus: Symptoms, Causes, and Treatment
    https://patient.info/chest-lungs/sars-and-mers-virus
    During the SARS-CoV-2 (COVID-19) pandemic the following general principles for treatment were developed: […] Mild illness was treated supportively in the community whilst isolating the infected person. Those people at higher risk of developing severe illness because of age or underlying medical conditions were recommended to receive paxlovid or remdesevir antiviral treatments. […] Moderate illness requiring hospitalisation for intravenous fluids and extra oxygen were also given remdesevir and dexamethasone – either alone or in combination. […] Severe illness was supported in a high dependency or critical care environment by intubation and ventilation (to help with breathing) and vasopressor medicines to help maintain blood pressure. The patients are usually kept lying on their tummies – clinicians call this 'nursing prone’. The patient will be kept in strict isolation with barrier procedures in place to prevent the spread of infection. If ventilation isn’t helping them recover then extra-corporeal membrane oxygenation (ECMO) may be tried. At the same time combinations of other antiviral treatments (baricitinib or tocilizumab) were given with dexamethasone.
  • #12 Treatment of severe acute respiratory syndrome
    https://pmc.ncbi.nlm.nih.gov/articles/PMC7088345/
    Many treatment options, including antiviral agents, immunosuppressive agents, convalescent plasma, immunoglobulin, noninvasive positive pressure ventilation (NIPPV), and traditional Chinese medicine (TCM), have been introduced on the basis of different rationales. […] Ribavirin has been chosen for use due to its wide spectrum of activity, despite being rather weak against SARS-CoV. Protease inhibitors are now under study because of the experimental evidence that they can inhibit the 3C-like (3CL) protease, which is essential for the life cycle of the SARS-CoV. […] Ribavirin was chosen for use empirically due to its broad antiviral spectrum and the assumption that it could provide coverage for the corticosteroid treatment, which was widely utilized at that time. In the end, over 90% of the patients in Hong Kong received ribavirin.
  • #13 Treatment Options for Severe Acute Respiratory Syndrome, Middle East Respiratory Syndrome, and Coronavirus Disease 2019: a Review of Clinical Evidence
    https://pmc.ncbi.nlm.nih.gov/articles/PMC7533202/
    Ribavirin which is a guanosine analogue has been demonstrated to have antiviral activity against a broad range of DNA and RNA viruses. In clinical practice, it has been mostly used in the treatment of respiratory syncytial virus infection, chronic hepatitis C infection, viral hemorrhagic fevers, and several other severe and life-threatening viral infections. In a prospective cohort study on the Hong Kong population, initial SARS patients were given antibiotics for pneumonia and oseltamivir for influenza infection. If the fever remained after 2 days from hospitalization, patients were given ribavirin in the combination with a low dose of prednisolone or hydrocortisone. High dose of methylprednisolone for 3 consecutive doses up to 6 doses were given after day 3 – 4 if fever persisted or lung shadow increased. Ribavirin and a low dose of corticosteroid were continuously given up to a max of 12 days until the resolution of lung opacity was completed. The combination of broad-spectrum antibiotics, ribavirin, and corticosteroids was also used to treat patients in other observational studies.
  • #14 Treatment of severe acute respiratory syndrome
    https://pmc.ncbi.nlm.nih.gov/articles/PMC7088345/
    Ribavirin is associated with a number of significant adverse effects. The most important one is anemia, with one study reporting a drop in hemoglobin of 2 g/dl or more in 49% of patients. […] In the quest for effective agents against the SARS-CoV, the protease inhibitor lopinavir, when combined with ribavirin, has been found to reach the synergistic inhibitory concentration against the SARS-CoV in laboratory testing. […] The findings from the above two studies suggest that LPV/r, when combined with ribavirin, may be an effective agent against SARS. […] The use of corticosteroids may, nevertheless, be associated with enhancement of viral replication due to suppression of the innate immune response. […] The use of corticosteroids in SARS, especially at high doses and for prolonged periods, has been accompanied by significant side effects.
  • #15 CEUFast – Severe Acute Respiratory Syndrome (SARS)
    https://ceufast.com/course/severe-acute-respiratory-syndrome-sars
    While there is no specific therapeutic regimen currently available for SARS patients, work continues to develop an immunization for prevention or specific antiviral agents to treat this condition. Care centers on supportive care measures and infection control to prevent spread. As many as 20% percent of patients require significant respiratory support, including mechanical ventilation. Family members must be advised regarding infection control procedures. Most practitioners use clinical protocols similar to those for community-acquired pneumonia when treating a suspected or probable SARS case. Broad spectrum antibiotics, including a flouroquininolone or macrolide are used. Patients in Hong Kong and Toronto were also treated with the antiviral ribavirin. Most clinicians do not recommend ribavirin because of the drugs toxicity, including hemolytic anemia and electrolyte imbalance.
  • #16 Treatment Options for Severe Acute Respiratory Syndrome, Middle East Respiratory Syndrome, and Coronavirus Disease 2019: a Review of Clinical Evidence
    https://pmc.ncbi.nlm.nih.gov/articles/PMC7533202/
    It was reported in the WHO meeting that an anti-HIV drug named lopinavir/ritonavir (LPV/r) could have the mortality risk reduction among patients with SARS. There were no deaths among 34 patients who received LPV/r combined with ribavirin, whereas 10% of 690 patients who received ribavirin alone had died at the 30 days from the onset of symptoms. However, the mortality rate was not significantly different between two groups. In another retrospective matched cohort study of Hong Kong SARS patients, the standard treatment of ribavirin and corticosteroid was provided to patients at the initial time of SARS confirmation. LPV/r (lopinavir 400mg and ritonavir 100 mg every 12 hours) was added to standard treatment as initial therapy, or it was given without ribavirin as a rescue therapy. Combination with LPV/r as the initial therapy significantly reduced the mortality on day 21, compared with ribavirin and corticosteroids alone.

    The European Medicines Agency recommends remdesivir positively for the treatment of SARS-CoV-2. […] The chemical structure of chloroquine (CQ) and hydroxychloroquine (HCQ) are closely related. […] Several studies have revealed that both drugs have antiviral activity in vitro through different mechanisms. […] In China 15 clinical trials were conducted to test the efficacy and safety of CQ or HCQ in the treatment of COVID-19, 8 of which were based on the administration of CQ, 6 were of HCQ, and another included both CQ and HCQ. […] Tocilizumab, an immunosuppressive agent, has also been found to be effective in vivo in COVID- 19 patients in China.

    While no treatment or cure was available at the time of the emergence of SARS, the emergence of a closely related disease COVID-19 lead to the rapid development of several antivirals and vaccines. Antivirals such as polymerase and protease inhibitors against SARS-CoV-2 are likely to be effective against SARS-CoV-1. COVID-19 vaccines may provide some level of cross-protection against SARS; however, the extent of such cross-protection remains to be studied. […] Controlling outbreaks relies on containment measures including: […] Personal preventive measures to prevent spread of the virus include frequent hand washing using soap or alcohol-based disinfectants. For those with a high risk of contracting the disease, such as health care workers, use of personal protective equipment, including a mask, goggles and an apron is mandatory. Whenever possible, household contacts should also wear a mask.

    https://pmc.ncbi.nlm.nih.gov/articles/PMC7088345/
    The best treatment strategy for severe acute respiratory syndrome (SARS) is still unknown. Ribavirin and corticosteroids were used extensively during the SARS outbreak. Ribavirin has been criticized for its lack of efficacy. Corticosteroids are effective in lowering the fever and reversing changes in the chest radiograph but have the caveat of encouraging viral replication. The effectiveness of corticosteroids has only been suggested by uncontrolled observations, and the role of these agents in therapy remains to be established by randomized controlled studies. Both ribavirin and corticosteroids have very significant side effects. The lopinavir/ritonavir combination has been shown to reduce the intubation rate and the incidence of adverse clinical outcomes when used with ribavirin. When patients deteriorate clinically despite treatment with ribavirin and corticosteroids, rescue treatment with convalescent plasma and immunoglobulin may be beneficial. Noninvasive positive pressure ventilation is a sound treatment for SARS patients with respiratory failure if administered with due precaution in the correct environment. Interferons and other novel agents may hold promise as useful anti-SARS therapies in the future. The experience with traditional Chinese medicine is encouraging, and its use as an adjuvant should be further investigated.

    Interferons (IFNs) have been known as important glycoprotein that can inhibit viral replication. In an open-label study of 22 SARS patients, oral prednisone 50 mg or intravenous methylprednisolone 40 mg was given every 12 hours. IFN alfa-1 was provided with an increasing dose from 9 g/d to 15 9 g/d during 2 to 10 days of the treatment. A combination of IFN alfa-1 and corticosteroid significantly decreased disease-related impaired oxygen saturation and creatinine kinase levels, compared with corticosteroid alone. […] Given the effectiveness of agents that were used in the treatment of SARS, Momattin et al. suggested the therapeutic schedule for oral ribavirin, LPN/r, peginterferon alfa-2a, and convalescent plasma as possible therapies for patients diagnosed with MERS. Ribavirin was suggested with the dose adjustment but the doses were still higher than those given to SARS patients. A similar treatment schedule with SARS for LPV/r (lopinavir 400 mg/ ritonavir 100 mg twice daily for 10 days) with or without ribavirin was proposed.

    As SARS is a viral disease, antibiotics do not have direct effect but may be used against bacterial secondary infection. Treatment of SARS is mainly supportive with antipyretics, supplemental oxygen and mechanical ventilation as needed. While ribavirin is commonly used to treat SARS, there seems to have little to no effect on SARS-CoV, and no impact on patient’s outcomes. There is currently no proven antiviral therapy. Tested substances, include ribavirin, lopinavir, ritonavir, type I interferon, that have thus far shown no conclusive contribution to the disease’s course. Administration of corticosteroids, is recommended by the British Thoracic Society/British Infection Society/Health Protection Agency in patients with severe disease and O2 saturation of 90%. […] People with SARS-CoV must be isolated, preferably in negative-pressure rooms, with complete barrier nursing precautions taken for any necessary contact with these patients, to limit the chances of medical personnel becoming infected. In certain cases, natural ventilation by opening doors and windows is documented to help decreasing indoor concentration of virus particles. […] Some of the more serious damage caused by SARS may be due to the body’s own immune system reacting in what is known as cytokine storm.

    In patients who deteriorated irrevocably despite receiving pulse methylprednisolone, convalescent plasma, obtained from patients who recovered from SARS, had been used as a last resort. […] Noninvasive positive pressure ventilation (NIPPV) is a form of ventilatory support through a tight-fitting facemask or nasal mask frequently administered in combination with continuous positive airway pressure or bi-level positive airway pressure for patients with impending respiratory failure. […] The present therapy of SARS is less than satisfactory, and much effort has been expended in looking for novel treatment modalities. […] The optimal treatment regimen for SARS remains elusive. Randomized controlled treatment trials should be done, especially through international collaboration, to discover the best form of therapy.

    Corticosteroid dosages should be high enough, especially in the severe cases, to abort the cytokine storm, and maintained for long enough to prevent the rebound phenomenon. […] Human gamma immunoglobulins have been used in selected SARS patients who continued to deteriorate despite treatment. […] Convalescent plasma collected from recovered SARS patients has been used in Hong Kong to treat severely ill patients not responding to corticosteroids. […] Despite all efforts, at least 50% of SARS patients would still develop acute hypoxemic respiratory failure, with up to 80% requiring supplemental oxygen.

    Severe acute respiratory syndrome is a coronavirus infection that causes flu-like symptoms. […] If doctors think a person may have SARS, the person is isolated in a room with a ventilation system that limits the spread of microorganisms in the air. […] SARS is caused by a coronavirus. SARS is much more severe than most other coronavirus infections, which usually cause only coldlike symptoms. However, the Middle East respiratory syndrome (MERS) and COVID-19 are other severe illnesses caused by a coronavirus. […] SARS is spread from person to person through close contact with an infected person or through airborne droplets that were coughed or sneezed out by an infected person. […] If doctors think a person may have SARS, the person is isolated in a room with a ventilation system that limits the spread of microorganisms in the air. In the first and only outbreak of SARS, such isolation kept the virus from being transmitted and eventually eliminated it. […] People with mild symptoms need no specific treatment.

    With SARS, the focus is on preventing the spread of infection. If a patient is suspected of having SARS, its vital to identify them quickly and isolate them, adopting adequate measures to control the infection and prevent transmission. […] A process that uses clinical and epidemiological criteria should be in place to promptly recognize patients with suspected SARS. Measures to control the infection include contact precautions (using gloves, gowns, and eye protection), droplet precautions (securing a private room for the patient and limiting their movement), and airborne precautions (using N-95 respirators and making sure the isolation room has a negative pressure environment). […] In the early stages of the SARS epidemic, corticosteroids were trialed as a treatment, but they did not prove to be beneficial.
