Gorączki krwotoczne
Leczenie

Gorączki krwotoczne (VHF) to grupa ciężkich chorób wirusowych charakteryzujących się ostrą gorączką, zwiększoną przepuszczalnością naczyń i zaburzeniami krzepnięcia, bez swoistego leczenia przyczynowego. Podstawą terapii jest leczenie podtrzymujące, obejmujące wyrównywanie zaburzeń wodno-elektrolitowych, monitorowanie ciśnienia tętniczego i objętości krążącej krwi, tlenoterapię, kontrolę drgawek oraz hemodializę w przypadku niewydolności nerek. Należy unikać NLPZ i aspiryny ze względu na ryzyko krwawień, preferując paracetamol. Rybawiryna wykazuje skuteczność w leczeniu gorączki Lassa (podawana przed 7. dniem choroby) oraz zakażeń hantawirusowych, natomiast jej efektywność w CCHF pozostaje niepotwierdzona. Przeciwciała monoklonalne, takie jak Inmazeb i Ebanga (FDA zatwierdzone dla wirusa Ebola) oraz MR191-N (badane dla wirusa Marburga), stanowią obiecujące opcje terapeutyczne. Leczenie powinno być dostosowane do fazy choroby: wczesna faza wymaga terapii przeciwwirusowej, natomiast faza późna – leków immunomodulujących.

Gorączki krwotoczne – wprowadzenie do leczenia

Gorączki krwotoczne (Viral Hemorrhagic Fevers, VHF) stanowią grupę potencjalnie śmiertelnych chorób zakaźnych wywoływanych przez różne rodziny wirusów. Charakteryzują się one ostrą gorączką, zwiększoną przepuszczalnością naczyń krwionośnych i zaburzeniami krzepnięcia. Dla większości gorączek krwotocznych nie istnieje swoiste leczenie przyczynowe. Podstawą postępowania terapeutycznego jest leczenie podtrzymujące, którego celem jest zapobieganie powikłaniom zagrażającym życiu, takim jak niewydolność narządowa i niekontrolowane krwawienia.12

Wczesne rozpoznanie choroby ma kluczowe znaczenie dla zwiększenia szans przeżycia pacjenta oraz zapobiegania zakażeniom szpitalnym. Pacjenci z objawami lub historią podróży wskazującą na możliwość zachorowania na gorączkę krwotoczną powinni być izolowani, a personel medyczny powinien stosować odpowiednie środki ochrony osobistej.12

Leczenie podtrzymujące gorączek krwotocznych

Leczenie podtrzymujące jest podstawą opieki nad pacjentami z gorączką krwotoczną. Ma ono kluczowe znaczenie dla poprawy wyników leczenia, ponieważ istnieją dowody na to, że agresywne, ukierunkowane na cel leczenie podtrzymujące ma zasadnicze znaczenie w zapobieganiu chorobowości i śmiertelności.1 Elementy leczenia podtrzymującego obejmują:

  • Wyrównywanie zaburzeń gospodarki wodno-elektrolitowej – podawanie płynów dożylnie w celu zapobiegania odwodnieniu i utrzymania równowagi elektrolitowej niezbędnej do prawidłowego funkcjonowania nerwów i mięśni12
  • Monitorowanie i utrzymywanie ciśnienia tętniczego oraz objętości krążącej krwi1
  • Tlenoterapia lub wentylacja mechaniczna w razie potrzeby1
  • Kontrola drgawek w przypadku ich wystąpienia1
  • Leczenie przeciwbólowe i objawowe1
  • Hemodializa w przypadku niewydolności nerek12

Należy unikać stosowania kwasu acetylosalicylowego (aspiryny) i niesteroidowych leków przeciwzapalnych (NLPZ), ponieważ zwiększają one ryzyko krwawienia.12 W przypadku gorączki zaleca się stosowanie paracetamolu.1

Swoiste leczenie przeciwwirusowe

Rybawiryna

Rybawiryna (Virazole, Rebetol) jest lekiem przeciwwirusowym o szerokim spektrum działania, aktywnym przeciwko wirusom wywołującym gorączki krwotoczne (z wyjątkiem wirusa Ebola) w systemach hodowli komórkowych.1 Lek ten wykazał skuteczność w leczeniu następujących gorączek krwotocznych:

  • Gorączka Lassarybawiryna znacząco zmniejsza śmiertelność, gdy jest podawana przed 7. dniem choroby osobom z grupy wysokiego ryzyka12
  • Krymsko-kongijska gorączka krwotoczna (CCHF) – rybawiryna hamuje wirus CCHF in vitro, ale jej skuteczność w praktyce klinicznej pozostaje niepotwierdzona12
  • Gorączka doliny Rift – leczenie rybawiryną skutkowało zmniejszoną śmiertelnością u gryzoni i małp zakażonych wirusem gorączki doliny Rift1
  • Zakażenia hantawirusowe – w Chinach rybawiryna znacząco zmniejszyła śmiertelność u pacjentów z gorączką krwotoczną z zespołem nerkowym1

Światowa Organizacja Zdrowia (WHO) zauważa, że istnieje obecnie znaczna niepewność co do skuteczności rybawiryny w leczeniu CCHF ze względu na brak dowodów klinicznych, a także optymalnych schematów dawkowania. Zaleca się, aby w miarę możliwości pacjenci leczeni rybawiryną byli włączani do randomizowanych badań klinicznych w celu oceny wyników klinicznych i bezpieczeństwa.1

Jedynym istotnym działaniem niepożądanym rybawiryny u ludzi jest możliwa do opanowania, odwracalna niedokrwistość.1 Inne możliwe działania niepożądane obejmują: ból głowy, bóle mięśni, suchość w ustach, utratę wagi, nudności i wahania nastroju.1

Terapie przeciwciałami monoklonalnymi

Dla niektórych gorączek krwotocznych opracowano specyficzne terapie przeciwciałami monoklonalnymi:

  • Inmazeb i Ebangaprzeciwciała monoklonalne zatwierdzone przez Amerykańską Agencję ds. Żywności i Leków (FDA) do leczenia zakażeń wirusem Ebola12
  • MR191-N – przeciwciało monoklonalne pozyskane od osoby, która przeżyła chorobę Marburga. W badaniach wykazano, że dwie dawki MR191-N mogą zapewnić ochronę do 100% nawet gdy leczenie rozpoczęto do pięciu dni po zakażeniu wirusem Marburga lub Ravn12
  • Przeciwciała monoklonalne specyficzne dla wirusa Lassa – obecnie są w fazie oceny klinicznej1

Inne metody leczenia swoistego

Inne potencjalne metody leczenia gorączek krwotocznych, które są badane lub stosowane w określonych sytuacjach, obejmują:

  • Osocze ozdrowieńców – transfuzja osocza ozdrowieńców z odpowiednimi dawkami specyficznych przeciwciał neutralizujących jest obecnie zalecanym leczeniem gorączki krwotocznej wywołanej przez wirus Junin; interwencja ta okazała się skuteczna w poprawie przebiegu klinicznego chorób i zmniejszeniu śmiertelności do mniej niż 1%1
  • Fawipirawir – lek przeciwwirusowy badany w leczeniu gorączki Lassa1
  • Terapia wyciszająca geny z wykorzystaniem małych interferujących RNA (siRNA) – wykazała dobre wyniki zarówno u świnek morskich, jak i u naczelnych innych niż człowiek w modelach zakażenia wirusem Ebola1
  • Modulacja czynników krzepnięcia i/lub aktywności cytokin – nowe obiecujące pole badań nad terapią gorączek krwotocznych1

Fazy choroby i podejście terapeutyczne

Na podstawie obserwacji klinicznych i parametrów immunowirusologicznych, przebieg ciężkich gorączek krwotocznych można podzielić na trzy fazy, które wymagają różnych podejść klinicznych:12

Faza inkubacji

Pierwsza faza rozpoczyna się narażeniem na wirusa i utrzymuje się przez cały okres bezobjawowy. Na tym etapie aktywna/bierna immunizacja i cząsteczki o bezpośrednim działaniu przeciwwirusowym są najbardziej skuteczną opcją farmakologiczną.1

Faza przed koagulopatią

Druga faza zbiega się z replikacją wirusa i ewentualną wiremią. Na tym etapie cząsteczki o bezpośrednim działaniu przeciwwirusowym mogą być nadal skuteczne.1

Faza koagulopatii

Trzecia i ostatnia faza charakteryzuje się wystąpieniem zaburzeń krzepnięcia wywołanych dysregulacją sieci cytokin (burza cytokinowa). Na tym etapie leki immunomodulujące (np. inhibitory czynników krzepnięcia i/lub cytokin prozapalnych) są jedyną sensowną opcją, chociaż ich rzeczywista skuteczność nie została jeszcze oceniona.1

Modele zwierzęce i doświadczenia kliniczne u ludzi wskazują, że wyniki leczenia pacjentów poprawiają się, gdy leczenie rozpoczyna się jak najwcześniej.1

Leczenie poszczególnych typów gorączek krwotocznych

Gorączka Lassa

Gorączka Lassa została po raz pierwszy rozpoznana w 1969 roku w północnej Nigerii, gdy dwie z trzech zakażonych pielęgniarek w szpitalu wiejskim zmarły.1 Leczenie obejmuje:

  • Rybawiryną – kontrolowane badanie kliniczne wykazało zwiększony wskaźnik przeżycia u pacjentów z gorączką Lassa leczonych rybawiryną. Wszyscy pacjenci z tą chorobą powinni obecnie otrzymywać ten lek1
  • Leczenie podtrzymujące – może wymagać wszystkich nowoczesnych urządzeń intensywnej opieki, w tym dializy nerkowej i wentylacji mechanicznej1
  • Równowagę płynów i elektrolitów, utrzymanie ciśnienia krwi i objętości krążenia oraz kontrolę drgawek1

Choroba wywołana przez wirus Ebola i gorączka Marburg

Leczenie obejmuje:

  • Leczenie podtrzymujące – może wymagać intensywnej opieki12
  • Przeciwciała monoklonalne Inmazeb i Ebanga – zatwierdzone przez FDA do leczenia zakażeń wirusem Ebola12
  • Ograniczenie inwazyjnych procedur – aby zmniejszyć ryzyko narażenia personelu medycznego na zakażenie1

Dla choroby wywołanej przez wirus Marburga obecnie nie ma zatwierdzonej szczepionki, jednak przeciwciało monoklonalne MR191-N wykazuje obiecujące wyniki w badaniach przedklinicznych.12

Krymsko-kongijska gorączka krwotoczna

Leczenie obejmuje:

  • Leczenie podtrzymujące – jest głównym elementem terapii12
  • Rybawiryną – hamuje wirus CCHF in vitro, ale jej skuteczność w praktyce klinicznej pozostaje niepotwierdzona12
  • Wczesną intensywną opiekę podtrzymującą – w tym zarządzanie płynami i leczenie określonych objawów, co może poprawić szanse przeżycia1

Gorączka denga

Gorączka denga typowo objawia się nagłym wystąpieniem wysokiej gorączki, bólu głowy, bólu mięśni i stawów oraz uogólnioną limfadenopatią. W cięższych przypadkach może prowadzić do krwotocznej gorączki denga, charakteryzującej się tendencją do krwawień i wstrząsem, które mogą być śmiertelne.1

  • Nie ma obecnie skutecznych schematów przeciwwirusowych dostępnych do leczenia, dlatego postępowanie obejmuje leczenie objawowe1
  • Staranne zarządzanie uzupełnianiem objętości wewnątrznaczyniowej jest kluczowe1
  • Proaktywne leczenie krwotoku1
  • Przyjęcie na oddział intensywnej terapii jest wskazane dla pacjentów z ciężką dengą1

Gorączka denga jest zwykle chorobą samoograniczającą się, ze wskaźnikiem śmiertelności poniżej 1% przy wczesnym wykryciu i dostępie do odpowiedniej opieki medycznej. W przypadku leczenia ciężkiej dengi wskaźnik śmiertelności wynosi 2-5%, ale w przypadku braku leczenia wskaźnik śmiertelności sięga nawet 20%.1

Szczepienia przeciwko gorączkom krwotocznym

Dla większości gorączek krwotocznych nie ma obecnie dostępnych szczepionek. Wyjątkami są:

  • Szczepionka przeciwko żółtej gorączce – jest głównie bezpieczna i skuteczna. Jednak rzadko mogą wystąpić poważne działania niepożądane. Szczepionka przeciwko żółtej gorączce nie jest przeznaczona dla dzieci poniżej 9 miesiąca życia, kobiet w ciąży lub osób z upośledzoną odpornością1
  • Szczepionka przeciwko wirusowi Ebola – chroni przed jednym typem wirusa Ebola. Jest przeznaczona dla pracowników służby zdrowia pracujących w obszarach występowania epidemii1
  • Szczepionka przeciwko argentyńskiej gorączce krwotocznej – została opracowana i skutecznie wdrożona w ramach argentyńskiego programu kontroli tej choroby1
  • Szczepionka przeciwko gorączce denga – obecnie dostępna w Ameryce Łacińskiej i Azji Południowo-Wschodniej. Jednak Światowa Organizacja Zdrowia zaleca, aby podawać ją tylko osobom, które wcześniej chorowały na dengę1

W miejscach, gdzie naturalnie występują gorączki krwotoczne, działania prewencyjne koncentrują się na unikaniu kontaktu ze zwierzęcymi i owadzimi nosicielami.1

Zapobieganie gorączkom krwotocznym

Ze względu na ograniczone możliwości leczenia, zapobieganie gorączkom krwotocznym jest kluczowe. Środki zapobiegawcze obejmują:

  • Szczepienia – tam, gdzie są dostępne (żółta gorączka, Ebola, argentyńska gorączka krwotoczna)1
  • Unikanie podróży do obszarów z aktywnymi ogniskami choroby1
  • Noszenie odzieży ochronnej1
  • Zapobieganie ukąszeniom owadów1
  • Unikanie kontaktu z zakażonymi gryzoniami1
  • Izolacja pacjentów z podejrzeniem gorączki krwotocznej1
  • Kontrola populacji gryzoni i owadów może zapobiec VHF1

Aspekty leczenia gorączek krwotocznych

Leczenie gorączek krwotocznych pozostaje wyzwaniem ze względu na ograniczone opcje terapeutyczne i potencjalnie wysoką śmiertelność. Pomimo praktycznych trudności w opiece nad pacjentami z gorączkami krwotocznym, właściwe kliniczne postępowanie nie jest daremne ani pozbawione naukowego uzasadnienia, ponieważ udowodniono, że agresywna opieka podtrzymująca i swoista terapia przeciwwirusowa (gdy jest wskazana) poprawiają wyniki leczenia pacjentów.1

Istnieje obecnie potrzeba opracowania znormalizowanych protokołów klinicznych zarządzania przypadkami gorączek krwotocznych, które integrują środki kontroli zakażeń z kompleksową opieką nad pacjentami. Pomimo przeszkód w zapewnieniu opieki pacjentom z gorączkami krwotocznym i ograniczonych, a nawet rozczarowujących danych klinicznych na temat skuteczności dostępnych klinicznie leków, zapewnienie dostępu do obiecujących nowych terapii w ramach protokołów stosowania ze względów humanitarnych w starannie kontrolowanych warunkach jest nie tylko etycznie uzasadnione, ale pilnie potrzebne, biorąc pod uwagę wysoką śmiertelność tych chorób i ich wpływ na zdrowie publiczne na poziomie krajowym i międzynarodowym.1

Ze względu na szeroki zakres patologii wirusów powodujących gorączki krwotoczne, większość algorytmów leczenia opiera się na dwóch głównych czynnikach: leczeniu przeciwwirusowym i wsparciu życiowym w celu zapobiegania niewydolności wielonarządowej. Współpraca lokalnych i międzynarodowych planów kontroli i zapobiegania chorobom będzie konieczna nie tylko do ograniczenia rozprzestrzeniania się chorób takich jak gorączki krwotoczne, ale także do zapewnienia finansowania i wsparcia dla wczesnego wykrywania i terapii podtrzymujących w celu poprawy wyników leczenia pacjentów.1

    https://bmcmedicine.biomedcentral.com/articles/10.1186/1741-7015-10-31
    The management of viral hemorrhagic fevers (VHFs) has mainly focused on strict infection control measures, while standard clinical interventions that are provided to patients with other life-threatening conditions are rarely offered to patients with VHFs. […] Given that patient outcomes improve when treatment is started as soon as possible, development and implementation of protocols to promptly identify and treat patients in the earliest phases of diseases are urgently needed. […] Different pharmacological options have been proposed to manage patients and, as for other life-threatening conditions, advanced life support has been proved effective to address multiorgan failure. […] Despite the practical difficulties of caring for VHF patients, a proper clinical case management of VHFs is neither futile nor does it lack of scientific rationale, as aggressive supportive care and specific antiviral therapy (whenever it is indicated) has been proved to improve patient outcomes.

    https://www.cdc.gov/viral-hemorrhagic-fevers/hcp/clinical-care/index.html
    Healthcare providers should notify their health department and CDC to determine a patient’s course of treatment. […] FDA-approved therapeutics do not exist for most viral hemorrhagic fevers. […] Supportive care is vital for patients with suspected or confirmed VHFs. […] Special precautions are needed to safely provide care like hemodialysis to VHF patients.

    Viral hemorrhagic fever is a severe potentially fatal infectious disease. […] There is increasing evidence that aggressive goal directed supportive treatment is essential in preventing morbidity and mortality. […] Directed specific anti-viral therapy is recommended in certain situations, based mainly on in-vitro, animal, or observational studies. […] Ribavirin has the greatest body of evidence suggesting its efficacy in the treatment of Lassa hemorrhagic fever, Crimean-Congo hemorrhagic fever, Hanta virus, and Rift valley fever. […] As therapeutic options remain extremely limited and the threat of this disease remains significant, prevention of disease via vaccination, vector control, public health education, and prevention of onward transmission remain a key part of public health control.

    https://www.mayoclinic.org/diseases-conditions/viral-hemorrhagic-fevers/diagnosis-treatment/drc-20351266
    There’s no treatment for most viral hemorrhagic fevers other than supportive care. […] The antiviral medicine ribavirin (Virazole) might shorten the course of some infections, such as Lassa fever. And the Food and Drug Administration has approved monoclonal antibody therapies Inmazeb and Ebanga to treat Ebola. […] Supportive care may help you feel better while your body fights the infection. For instance, to keep from losing too much fluid, called dehydration, you might need to get fluids through a vein in an arm, called IV. This can help keep the balance of minerals needed for nerves and muscles to work, called electrolytes. […] Kidney dialysis might help some people. Kidney dialysis removes wastes from the blood when the kidneys fail.
  • #1 Management of Patients With Suspected Viral Hemorrhagic Fever
    https://www.cdc.gov/mmwr/preview/mmwrhtml/00037085.htm
    Lassa fever was first recognized in 1969 in northern Nigeria when two of three nurses infected in a rural hospital died. […] Treatment is supportive and may require all the modern intensive-care facilities, including renal dialysis and mechanical ventilation. It is essential to pay attention to fluid and electrolyte balance, maintenance of blood pressure and circulatory volume, and control of seizures. […] A controlled clinical trial has shown an increased survival rate for Lassa fever patients treated with ribavirin. All patients with the disease should now receive this drug. […] Treatment is supportive and may require intensive care. Limited information exists on the efficacy of antiviral drugs or immune plasma to prevent or ameliorate Ebola hemorrhagic fever. […] The treatment is the same as for Ebola virus disease, and the same comments about antiviral drugs and the use of immune plasma apply.

    Theres no specific cure for viral hemorrhagic fever. But there are antiviral treatments for a few VHFs. Most of the time, healthcare providers treat you by managing your symptoms and keeping your condition stable. Treatments might include: […] Ribavirin. […] Inmazeb and Ebanga (monoclonal antibody treatments approved for Ebola). […] Supplemental oxygen or mechanical ventilation. […] Intravenous (IV) fluids. […] Medications to manage symptoms, like pain or nausea.

    Generally, there is no known cure or treatment for these diseases. People with these illnesses may get supportive treatment. This may include getting fluids or assistance with breathing and pain relievers. An antiviral medicine may help some people with Ebola and Lassa fever. […] No cure or treatment is available for most of these illnesses.

    https://www.amboss.com/us/knowledge/viral-hemorrhagic-fevers/
    Treatment is typically supportive, but antivirals may be used in some cases (e.g., ribavirin in Lassa fever). […] Supportive treatment includes management of fluids and electrolyte balance, maintenance of blood pressure and oxygenation, analgesics for pain and fever, and blood products in patients with severe thrombocytopenia, coagulopathy, hemorrhage. […] Medical treatment: Ribavirin may be used in some cases (e.g., Lassa fever). […] Aspirin and NSAIDs should be avoided in VHFs because they are associated with an increased risk of bleeding!
  • #1 Viral haemorrhagic fevers | MSF Medical Guidelines
    https://medicalguidelines.msf.org/en/viewport/CG/english/viral-haemorrhagic-fevers-16690024.html
    Aetiological treatment: ribavirine for Lassa fever and Crimean-Congo fever. […] Symptomatic treatment: Fever: paracetamol (Chapter 1). Acetylsalicylic acid (aspirin) is contra-indicated. […] For Ebola and Marburg haemorrhagic fevers: invasive procedures must be strictly limited. Health care staff is at risk of contamination when inserting and maintaining IV lines. An IV line must be well secured so that the patient, often confused, cannot pull it out.
  • #1 Prospects for treatment of viral hemorrhagic fevers with ribavirin, a broad-spectrum antiviral drug – PubMed
    https://pubmed.ncbi.nlm.nih.gov/2546248/
    Ribavirin, a broad-spectrum antiviral drug, is active against hemorrhagic fever viruses (with the exception of Ebola virus) in cell culture systems. […] In model infections with arenaviruses in guinea pigs and monkeys, ribavirin has demonstrated both prophylactic and therapeutic efficacy. […] In human cases of Lassa fever, it significantly reduces mortality when administered before day 7 of illness to persons at high risk. […] Ribavirin therapy resulted in reduced mortality in rodents and monkeys infected with Rift Valley fever virus; prophylactic administration to volunteers infected with sandfly fever virus, Sicilian strain, prevented development of illness. […] Ribavirin increased the number of survivors and the mean time to death in suckling mice infected with Crimean-Congo hemorrhagic fever virus and in suckling mice infected with Hantaan virus. […] In the People’s Republic of China, ribavirin significantly reduced mortality in patients with hemorrhagic fever with renal syndrome. […] The only important adverse effect of ribavirin in humans is manageable, reversible anemia.
  • #1 Management of Patients With Suspected Viral Hemorrhagic Fever
    https://www.cdc.gov/mmwr/preview/mmwrhtml/00037085.htm
    Treatment is supportive and may require intensive care. Ribavirin inhibits CCHF virus in vitro, but its efficacy in clinical practice remains unconfirmed. […] Ribavirin is recommended both therapeutically for patients with Lassa fever and prophylactically for high-risk contacts of such patients. […] Ribavirin has been shown effective against some of the Bunyaviridae in vitro, and its use in patients with CCHF seems reasonable, although no clinical experience is available.
  • #1
    https://www.who.int/news-room/fact-sheets/detail/crimean-congo-haemorrhagic-fever
    Early intensive supportive care including fluid management and treatment of specific symptoms, can improve survival chance. […] There is currently no specific treatment approved for Crimean-Congo haemorrhagic fever. The antiviral drug ribavirin has been given off label as treatment; however, there is currently considerable uncertainties about its efficacy on the outcome of patients with CCHF given the lack of clinical evidence, as well as on its optimal dosing regimens. Whenever possible, if the decision is to use ribavirin to treat patients, they must be enrolled into a randomized clinical trial with ribavirin or other investigational therapeutics to assess clinical outcomes and safety.

    https://www.lybrate.com/topic/hemorrhagic-fever
    There is no treatment for the hemorrhagic fever and vaccinations exist for only a few of the infections. The best approach for most viral hemorrhagic fever is to take preventive measure against them. […] Even though there is no clear treatment for the conditions, Ribavirin is an important drug, which can shorten the course of the infection. Patients also often require supportive care in order to manage the symptoms related to the disease. […] People suffering from severe forms of the hemorrhagic fever should seek treatment immediately. In such cases, internal bleeding may be caused, which can be fatal. The treatment will help the patient manage the symptoms and prevent damage to any organs in the body. […] Ribavirin is the only major drug used to treat hemorrhagic fevers caused by viruses. The medicine does not cause severe side effects, but may cause headache, muscle pain, dry mouth, weight loss, nausea and mood swings. Apart from this, there are no major side effects from the drug.
  • #1 Viral Hemorrhagic Fever Treatment Developed
    https://www.genengnews.com/news/viral-hemorrhagic-fever-treatment-developed/
    Filoviruses such as Ebola often spread rapidly and lead to hemorrhagic fevers in humans with extremely high morbidity and mortality rates. The development of therapeutics to treat these deadly viral outbreaks are essential to help infected patients and minimize the public health threat. […] Now, a team of researchers from The University of Texas Medical Branch at Galveston, Mapp Biopharmaceutical, and Vanderbilt University have developed an antibody treatment that successfully protected nonhuman primates against the deadly Marburg and Ravn viruses, relatives of Ebola, even when administered five days after infection. […] Findings from the new study showed that the experimental treatment cured 100% of guinea pigs and rhesus monkeys in late stages of infection with lethal levels of Marburg and Ravn viruses.

    Appropriate management of individuals suspected to have viral hemorrhagic fever includes early diagnosis to both increase chances of survival and prevent nosocomial infections. Patients with symptoms or travel history suggestive of these diseases should be isolated, and all staff caring for persons under investigation should wear appropriate personal protective equipment (referred to as viral hemorrhagic fever isolation precautions). Research regarding treatment is ongoing; however, the cornerstone of current treatment is supportive care. […] Lassa virus – Ribavirin has been shown to improve treatment outcomes when given early in the disease course; however, studies have been limited. Newer agents such as favipiravir and LASV-specific monoclonal antibodies are currently being evaluated. There are currently no effective vaccines for Lassa fever.

    Therefore, a case definition that can identify VHF patients in the early phases of diseases is urgently needed. […] The transfusion of immune convalescent plasma with adequate doses of specific neutralizing antibodies is the current recommended treatment for Junn virus VHF; this intervention has been proved to be effective in improving clinical course of diseases and reducing mortality to less than 1%. […] Gene-silencing treatment using small interfering RNAs (siRNA) has given good results both in guinea pigs and non-human primate Ebola infection models. […] Ribavirin is an antiviral drug currently recommended for prophylaxis and treatment of arenaviruses and bunyaviruses. […] High-throughput screening (HTS) of small molecular libraries, has recently emerged as a novel promising way to find new candidates molecules for VHF therapy.

    Several indirect lines of evidence suggest that modulating coagulation factors and/or cytokines activity may represent a new promising field of investigation for VHF therapy. […] Proper intensive care should be provided to all patients with VHF as for patients with other life-threatening conditions unrelated to VHF. […] There is currently a need to develop standardized clinical protocols for VHF clinical case management that integrate infection control measures with comprehensive care for patients. […] Despite the obstacles to provide care for VHF patients, and the limited, even disappointing clinical data on the efficacy of clinically available drugs, we believe that providing access to promising new therapeutics, under compassionate use protocols in carefully controlled settings is not only ethically justified but urgently needed, given the high lethality of these diseases and the impact on national and international public health.

    Beside high-level standards of safety for HCWs, which should be similar to those provided to bio-safety laboratory level 4 (BSL-4) personnel, a comprehensive protocol for clinical management of VHFs may not exclude high standards of care for patients. […] In theory patient care should include two main components. These are: (1) specific antiviral treatment (which includes compassionate or investigational use of therapeutic agents based on data from phase 1/2/3 trials, non-randomized studies or single case reports); and (2) advanced life support to prevent multiorgan failure. […] Based on clinical observations and on immunovirological parameters, the course of severe VHFs can be divided into three phases that require different clinical approaches; that is, incubation, precoagulopathy and coagulopathy.

    The first phase begins with exposure to the virus and persists throughout the presymptomatic period. At this level, active/passive immunization and molecules with direct antiviral activity are the most effective pharmacological option. […] The second phase coincides with virus replication and the eventual viremia. At this stage molecules with direct antiviral activity can be still effective. […] The third and last phase is characterized by the onset of coagulation abnormalities driven by the dysregulation of the cytokine network (cytokine storm). […] At this stage immune-modulating drugs (for example, inhibitors of coagulation factors and/or proinflammatory cytokines) are the only sensible option although their actual efficacy is yet to be assessed. […] Animal models and clinical experience in humans indicate that patient outcomes improve when treatment is started as soon as possible.

    Crimean-Congo hemorrhagic fever – Treatment largely remains supportive. Ribavarin has demonstrated an antiviral effect against this virus in vitro. There is currently no effective vaccine for humans. […] Ebola virus disease and Marburg hemorrhagic fever – Treatment involves supportive care. There are currently no vaccines available against the Marburg virus. There is currently one Food and Drug Administration approved Ebola vaccine against the Zaire ebolavirus. […] Dengue fever – There are currently no effective antiviral regimens available for treatment, thus management involves supportive care. One vaccine is currently available in Latin America and Southeast Asia.

    https://emedicine.medscape.com/article/969877-treatment
    Dengue fever typically presents with a sudden onset of high fever, headache, muscle and joint pain, and generalized lymphadenopathy. […] In more severe cases, dengue can lead to dengue hemorrhagic fever, characterized by a bleeding tendency and shock, which can be fatal. […] Diagnosis is made through serologic testing and polymerase chain reaction (PCR), whereas treatment focuses on symptomatic relief. For dengue hemorrhagic fever, careful management of intravascular volume replacement is crucial. […] Dengue fever typically is a self-limited disease with a mortality rate of less than 1% when detected early and with access to proper medical care. When treated, severe dengue has a mortality rate of 2-5%, but, when left untreated, the mortality rate is as high as 20%. […] Successful management of severe dengue requires intravascular volume replacement, with careful attention to fluid management and proactive treatment of hemorrhage. Admission to an intensive care unit is indicated for patients with severe dengue.

    The first phase begins with exposure to the virus and persists throughout the presymptomatic period. At this level, active/passive immunization and molecules with direct antiviral activity are the most effective pharmacological option. […] The second phase coincides with virus replication and the eventual viremia. At this stage molecules with direct antiviral activity can be still effective. […] The third and last phase is characterized by the onset of coagulation abnormalities driven by the dysregulation of the cytokine network (cytokine storm). […] At this stage immune-modulating drugs (for example, inhibitors of coagulation factors and/or proinflammatory cytokines) are the only sensible option although their actual efficacy is yet to be assessed. […] Animal models and clinical experience in humans indicate that patient outcomes improve when treatment is started as soon as possible.
