Wirus zika
Leczenie

Wirus Zika (ZIKV), należący do rodziny Flaviviridae, wywołuje zazwyczaj łagodne zakażenia, jednak u kobiet w ciąży może prowadzić do poważnych wad wrodzonych, takich jak mikrocefalia. Leczenie jest objawowe i obejmuje odpoczynek, nawodnienie oraz stosowanie paracetamolu; unika się NLPZ i aspiryny ze względu na ryzyko krwawień i zespołu Reye’a. Kobiety ciężarne z potwierdzonym zakażeniem wymagają ścisłego monitorowania ultrasonograficznego co 3-4 tygodnie oraz konsultacji specjalistycznych. Powikłania neurologiczne, w tym zespół Guillaina-Barrégo, leczy się wspomagająco, stosując dożylne immunoglobuliny lub plazmaferezę w ciężkich przypadkach. Brak jest specyficznych leków przeciwwirusowych, jednak badania in vitro wskazują na potencjał leków takich jak chlorochina, hydroksychlorochina, sofosbuwir, iwermektyna czy azytromycyna.

Leczenie wirusa zika

Wirus zika (ZIKV) to jednoniciowy wirus RNA należący do rodziny Flaviviridae i rodzaju Flavivirus. Zakażenie wirusem zika u większości osób przebiega łagodnie i ustępuje samoistnie. Jednak u niektórych osób, zwłaszcza u kobiet w ciąży, może prowadzić do poważnych powikłań, w tym wad wrodzonych u płodu.1 Obecnie nie ma szczepionek zapobiegających ani leków leczących zakażenie wirusem zika.23 W tej sekcji omówimy dostępne metody leczenia objawowego oraz badania nad potencjalnymi metodami terapeutycznymi.

Leczenie objawowe

Leczenie zakażenia wirusem zika jest przede wszystkim objawowe. Ze względu na brak swoistych leków przeciwwirusowych, terapia koncentruje się na łagodzeniu objawów i zapobieganiu powikłaniom.4 Zalecenia dotyczące leczenia objawowego obejmują:

  • Odpoczynek – kluczowy element wspomagający organizm w walce z infekcją56
  • Zwiększenie podaży płynów w celu zapobiegania odwodnieniu78
  • Stosowanie leków przeciwbólowych i przeciwgorączkowych, głównie paracetamolu (acetaminofenu)910
  • W przypadku świądu skóry – stosowanie leków przeciwhistaminowych11
  • W przypadku suchości oczu – stosowanie sztucznych łez12

Istotne jest, aby unikać stosowania kwasu acetylosalicylowego (aspiryny) i innych niesteroidowych leków przeciwzapalnych (NLPZ) do czasu wykluczenia zakażenia wirusem dengi, ponieważ leki te mogą zwiększać ryzyko krwawienia w przypadku infekcji dengą.131415 W populacji pediatrycznej aspiryna może również zwiększać ryzyko zespołu Reye’a.1617

Objawy zakażenia wirusem zika zwykle ustępują samoistnie w ciągu około tygodnia.18 W przypadku nasilenia objawów lub wystąpienia powikłań należy poszukać pomocy medycznej.19

Szczególne zalecenia dla kobiet w ciąży

Kobiety w ciąży z potwierdzonym zakażeniem wirusem zika wymagają szczególnej opieki medycznej i ścisłego monitorowania ze względu na ryzyko przeniesienia wirusa na płód i możliwość wystąpienia wad wrodzonych, w tym małogłowia (mikrocefalia).2021

Zalecenia dla kobiet w ciąży z zakażeniem wirusem zika obejmują:

  • Skierowanie do specjalisty położnictwa lub specjalisty w zakresie chorób zakaźnych układu rozrodczego2223
  • Regularne badania ultrasonograficzne co 3-4 tygodnie w celu monitorowania rozwoju płodu242526
  • Ścisłe monitorowanie wzrostu płodu i ocena anatomii płodu pod kątem cech związanych z zakażeniem wewnątrzmacicznym27
  • W przypadku wykrycia małogłowia, zwapnień wewnątrzczaszkowych lub innych nieprawidłowości – konsultacja z neonatologiem i specjalistą od chorób zakaźnych wieku dziecięcego28

Kobiety w ciąży powinny unikać podróży do obszarów, gdzie występuje wirus zika, a jeśli nie mogą tego uniknąć, powinny stosować środki zapobiegające ukąszeniom komarów i poddać się badaniom po powrocie.29

Leczenie powikłań neurologicznych

Zakażenie wirusem zika może prowadzić do poważnych powikłań neurologicznych, w tym zespołu Guillaina-Barrégo (GBS). WHO zaleca optymalne leczenie wspomagające u pacjentów z GBS, obejmujące:

  • Częste badania neurologiczne30
  • Monitorowanie funkcji życiowych31
  • Monitorowanie funkcji oddechowych w celu zmniejszenia prawdopodobieństwa powikłań (np. zakrzepów krwi, niewydolności oddechowej)32

Pacjenci, u których objawy szybko się nasilają lub którzy nie są w stanie chodzić, powinni otrzymać dożylne leczenie immunoglobulinami lub terapeutyczną wymianę osocza.33 W przypadku zapalenia mózgu wywołanego wirusem zika leczenie obejmuje głównie leczenie powikłań, takich jak bóle, napady padaczkowe lub podwyższone ciśnienie śródczaszkowe.34

Badania nad nowymi metodami leczenia

Wobec braku swoistych leków przeciwwirusowych do leczenia zakażenia wirusem zika, prowadzone są intensywne badania nad potencjalnymi lekami, które mogłyby być skuteczne przeciwko temu patogenowi. Poniżej przedstawiono główne kierunki badań.

Repozycjonowanie istniejących leków

Jednym z podejść do opracowania terapii przeciwko wirusowi zika jest wykorzystanie istniejących leków zatwierdzonych przez FDA do innych wskazań. Badania przesiewowe zidentyfikowały kilka grup leków wykazujących aktywność przeciwko wirusowi zika in vitro:3536

  • Leki przeciwmalaryczne – chlorochina i meflochina wykazują działanie przeciwko wirusowi zika in vitro i są bezpieczne do stosowania we wszystkich trymestrach ciąży3738
  • Hydroksychlorochina – badania na modelach mysich wykazały, że lek ten skutecznie blokuje przenoszenie wirusa na płód poprzez ingerencję w proces autofagii39
  • Leki przeciwwirusowe – interferon, sofosbuwir, galidesiwir wykazują aktywność przeciwwirusową in vitro4041
  • Leki przeciwpasożytnicze – iwermektyna wykazuje działanie przeciwwirusowe4243
  • Antybiotyki – azytromycyna zmniejsza zakaźność wirusa44
  • Suramina – lek przeciwpasożytniczy zatwierdzony przez FDA, wykazujący działanie przeciwwirusowe przeciwko flawiwirusom45
  • Leki stosowane w leczeniu HIV – rilpiwiryna, należąca do klasy nienukleozydowych inhibitorów odwrotnej transkryptazy (NNRTI), blokuje replikację wirusa zika poprzez działanie na enzymy niezbędne do namnażania zarówno wirusa HIV, jak i zika4647
  • Niklozamid – lek przeciw pasożytom jelitowym, który w badaniach wykazał aktywność przeciwko replikacji wirusa zika i jest uznawany za potencjalnie bezpieczny dla kobiet w ciąży48

Rozwój nowych terapii

Oprócz repozycjonowania istniejących leków, prowadzone są badania nad nowymi terapiami przeciwko wirusowi zika:

  • Inhibitory proteazy NS2B-NS3 – proteaza ta jest dobrze zachowana w całym rodzaju Flavivirus i nie uległa mutacjom w sekwencji proteazy wirusa zika od 1967 roku, co czyni ją atrakcyjnym celem wirusowym49
  • Inhibitory polimerazy RNA zależnej od RNA (RdRp) – możliwe dzięki dostępności struktur krystalicznych białka NS5 wirusa zika50
  • Inhibitory helikazy – ST-610, najsilniejszy inhibitor helikazy flawiwirusów51
  • Inhibitory metylotransferazy – opracowane przy użyciu modelowania molekularnego52
  • Peptydy przeciwwirusowe przenikające barierę krew-mózg – zaprojektowane peptydy wykazały skuteczność terapeutyczną na mysim modelu zakażenia wirusem zika, chroniąc przed śmiertelnością i znacznie zmniejszając objawy kliniczne, wiremię i neurozapalenie53
  • Strategie ukierunkowane na szlak cholesterolu – badania wykazały, że leczenie agonistą LXR lub inhibitorem SREBP-2 łagodziło nieprawidłowości oczne związane z zakażeniem wirusem zika, sugerując, że celowanie w komponenty szlaku cholesterolu, takie jak ABCG1 i SREBP-2, może oferować obiecujące strategie terapeutyczne5455

Postępy w rozwoju szczepionek

Chociaż obecnie nie istnieje zatwierdzona szczepionka przeciwko wirusowi zika, prowadzone są intensywne badania nad jej opracowaniem:5657

  • Światowa Organizacja Zdrowia sugeruje, że priorytetem powinno być opracowanie szczepionek inaktywowanych i innych szczepionek nie zawierających żywych wirusów, które są bezpieczne do stosowania u kobiet w ciąży58
  • W marcu 2017 roku szczepionka DNA została zatwierdzona do badań klinicznych fazy 2. Ta szczepionka składa się z małego, kolistego fragmentu DNA, znanego jako plazmid, który wyraża geny dla białek otoczki wirusa zika59
  • Szczepionki podjednostkowe i inaktywowane również weszły w fazę badań klinicznych60

Wyzwaniem w opracowaniu skutecznej szczepionki przeciwko wirusowi zika, podobnie jak w przypadku innych arbowirusów, jest sporadyczny i nieprzewidywalny charakter epidemii tego wirusa.61

Potencjalne zastosowania terapeutyczne wirusa zika

Interesującym kierunkiem badań jest wykorzystanie wirusa zika jako narzędzia terapeutycznego w walce z niektórymi rodzajami nowotworów:

Leczenie nowotworów mózgu

Badania wskazują, że wirus zika może być potencjalnie wykorzystany jako środek onkolityczny w leczeniu glejaka wielopostaciowego (GBM):62

  • Atenuowane szczepy szczepionkowe wirusa zika (ZIKV-LAV) wykazują silne działanie onkolityczne w komórkach ludzkiego glejaka wielopostaciowego (GBM) bez produktywnego zakażania komórek niebędących komórkami nowotworowymi, takich jak terminalnie zróżnicowane ludzkie neurony i pierwotne śródbłonki63
  • Zakażenie ZIKV-LAV w ludzkich komórkach GBM prowadzi do apoptozy i litycznej śmierci komórek, szczególnie na drodze pyroptozy, w późnej fazie zakażenia64
  • Zmniejszona neurotropizm zwiększa selektywność nowotworową ZIKV-LAV i zapewnia szersze okno terapeutyczne w porównaniu do dzikiego typu wirusa zika65

Leczenie neuroblastomy

Badania na modelach mysich wykazały, że wirus zika może być skuteczny w leczeniu neuroblastomy – jednego z najczęstszych nowotworów wieku dziecięcego:6667

  • Wstrzyknięcie wirusa zika do guzów neuroblastomy spowodowało niemal całkowitą utratę wielkości guza6869
  • Najwyższa testowana dawka doprowadziła do całkowitej eliminacji guza70
  • Po czterech dodatkowych tygodniach nie wykryto dalszego wzrostu guza, co sugeruje, że pacjenci leczeni wirusem zika mieliby większe szanse na przeżycie71
  • Myszy nie rozwinęły żadnych objawów zakażenia wirusem zika ani żadnych skutków ubocznych72

Badania wykazały, że nowotwory wykazujące ekspresję białka CD24 są podatne na działanie wirusa zika, co otwiera drzwi do wykorzystania wirusa zika jako metody leczenia.7374 Badacze zaznaczają jednak, że wykorzystanie wirusa zika jako terapii przeciwnowotworowej będzie wymagało przeprowadzenia szeroko zakrojonych dodatkowych badań obejmujących bezpieczeństwo i skuteczność.7576

Wyzwania w opracowaniu leków przeciwko wirusowi zika

Opracowanie skutecznych leków przeciwko wirusowi zika napotyka na szereg wyzwań:77

  • Leki powinny być zdolne do przekraczania bariery krew-mózg i bariery łożyskowej u kobiet w ciąży78
  • Leki muszą być bezpieczne do stosowania w czasie ciąży79
  • Zatwierdzone leki przeciwko wirusowi zika powinny mieć rozsądną cenę, ponieważ większość obszarów występowania wirusa zika to kraje tropikalne i subtropikalne o ograniczonych zasobach80
  • Zmienność antygenowa między różnymi szczepami, a nawet w obrębie tego samego szczepu wirusa zika, może stanowić przeszkodę w projektowaniu leków81

Zalecenia dotyczące profilaktyki

Wobec braku szczepionki i swoistego leczenia, profilaktyka odgrywa kluczową rolę w zapobieganiu zakażeniom wirusem zika:82

  • Zapobieganie ukąszeniom komarów:
    • Stosowanie środków odstraszających owady zawierających DEET, pikarydynę lub olejek z eukaliptusa cytrynowego83
    • Noszenie koszul z długimi rękawami, długich spodni, skarpet i kapeluszy w celu ochrony skóry84
    • Używanie moskitier85
  • Zapobieganie przenoszeniu drogą płciową:
    • Używanie prezerwatyw lub powstrzymanie się od aktywności seksualnej w przypadku podróży do obszarów, gdzie występuje wirus zika86
    • Mężczyźni powinni unikać ryzyka zajścia w ciążę ich partnerki (abstynencja lub używanie prezerwatyw) przez co najmniej sześć miesięcy po narażeniu lub początkowych objawach87
    • Kobiety powinny unikać zajścia w ciążę (abstynencja lub używanie prezerwatyw) przez co najmniej 8 tygodni po narażeniu lub początku objawów88
  • Zalecenia dla kobiet w ciąży:
    • Unikanie podróży do obszarów, gdzie występuje wirus zika89
    • W przypadku konieczności podróży, konsultacja z lekarzem i ścisłe przestrzeganie kroków zapobiegających ukąszeniom komarów90

Podsumowanie i perspektywy

Leczenie zakażenia wirusem zika pozostaje głównie objawowe, opierając się na odpoczynku, nawodnieniu i stosowaniu paracetamolu w celu złagodzenia bólu i gorączki. Szczególnej opieki wymagają kobiety w ciąży z potwierdzonym zakażeniem, które powinny być monitorowane pod kątem potencjalnych wad wrodzonych u płodu.9192

Intensywne badania nad potencjalnymi lekami przeciwko wirusowi zika obejmują zarówno repozycjonowanie istniejących leków (chlorochina, hydroksychlorochina, sofosbuwir, iwermektyna), jak i opracowywanie nowych terapii ukierunkowanych na kluczowe białka wirusowe (proteaza NS2B-NS3, polimeraza RdRp, helikaza, metylotransferaza).9394

Obiecujące wyniki dają również badania nad wykorzystaniem wirusa zika jako środka onkolitycznego w leczeniu glejaka wielopostaciowego i neuroblastomy.9596 Jednocześnie trwają prace nad szczepionkami, z naciskiem na szczepionki inaktywowane i podjednostkowe, które byłyby bezpieczne dla kobiet w ciąży.9798

Wobec braku swoistego leczenia, zapobieganie ukąszeniom komarów i transmisji seksualnej wirusa pozostaje kluczową strategią w walce z zakażeniami wirusem zika.99 Szczególną ostrożność powinny zachować kobiety w ciąży i planujące ciążę, unikając podróży do obszarów endemicznych lub stosując rygorystyczne środki ochronne.100

  • #16 Zika Virus Treatment & Management: Approach Considerations, Medical Care, Complications
    https://emedicine.medscape.com/article/2500035-treatment
    Zika virus (ZIKV) infection usually is mild and self-limited. There are no specific FDA-approved treatment options or vaccines for treatment and prevention of Zika virus infection. […] Supportive care with rest and adequate fluid hydration is advised. Symptoms such as fever and pain can be controlled with acetaminophen and pruritic rash with antihistamines. Use of nonsteroidal anti-inflammatory drugs (NSAIDs) in patients with unconfirmed Zika virus infection should be avoided since the use of such drugs in dengue fever is associated with hemorrhagic risk and risk for Reye syndrome in the pediatric population. […] The WHO recommends optimal supportive care in patients with Guillain-Barr syndrome, including frequent neurologic examinations, testing of vital signs, and respiratory function monitoring to decrease the likelihood of complications (eg, blood clots, respiratory failure). Patients whose symptoms are escalating rapidly or who are unable to walk should receive intravenous immunoglobulin therapy or therapeutic plasma exchange.

    Currently, there is no specific antiviral treatment plan for Zika virus infections, nor has a vaccine yet been developed. Doctors thus typically treat the set of active virus symptoms presented during consultation and testing. […] As the symptoms are typically flu-like in nature, doctors will recommend the following: Plenty of rest, Plenty of fluid-intake (water, broths and juices will help to prevent dehydration), The taking of over-the-counter medications, such as acetaminophen or ibuprofen to reduce fever, aches and pains. […] Treatment recommendations will take into consideration any other medications and supplements (including herbal products) already being taken, so as to avoid adverse drug interactions. If it is determined during the initial consultation that aspirin or NSAIDS (non-steroidal anti-inflammatory medications) were used to treat symptoms before a specific viral infection was diagnosed, a doctor will have requested immediate discontinuation. Until dengue fever is ruled out, none of these medication types will be safe to take as they can lead to internal bleeding (haemorrhage). […] Symptoms of Zika virus should clear within a week (approximately 7 days).
  • #19 Zika virus | Better Health Channel

    Zika virus is a mosquito-borne virus that is associated with neurodegenerative diseases, including GuillainBarr syndrome and congenital Zika syndrome. As Zika virus targets the nervous system, there is an urgent need to develop therapeutic strategies that inhibit Zika virus infection in the brain. Here, we have engineered a brain-penetrating peptide that works against Zika virus and other mosquito-borne viruses. We evaluated the therapeutic efficacy of the peptide in a lethal Zika virus mouse model exhibiting systemic and brain infection. Therapeutic treatment protected against mortality and markedly reduced clinical symptoms, viral loads and neuroinflammation, as well as mitigated microgliosis, neurodegeneration and brain damage. […] In addition to controlling systemic infection, the peptide crossed the bloodbrain barrier to reduce viral loads in the brain and protected against Zika-virus-induced bloodbrain barrier injury. Our findings demonstrate how engineering strategies can be applied to develop peptide therapeutics and support the potential of a brain-penetrating peptide to treat neurotropic viral infections.

    Wayne State University researchers uncover potential treatment targets for Zika virus-related eye abnormalities. Groundbreaking research led by Professor Ashok Kumar and Postdoctoral Fellow Sneha Singh is offering promising opportunities for therapeutic interventions for Zika virus-related eye abnormalities. A groundbreaking study published in the journal iScience presents crucial insights into the ocular effects of Zika virus infection during pregnancy and offers promising avenues for therapeutic intervention. Despite the ZIKV infection causing severe neurological and ocular abnormalities in infants, no specific vaccines or antiviral treatments are available. Our study aimed to uncover the molecular mechanisms underlying ZIKV-related eye abnormalities, with a focus on cellular metabolism. By elucidating the roles of key players in cholesterol metabolism, we sought to identify potential targets for therapeutic intervention. In vivo studies using mouse models of ZIKV-induced chorioretinal lesions revealed that treatment with an LXR agonist or SREBP-2 inhibitor mitigated ocular abnormalities associated with ZIKV infection. Our findings suggest that targeting cholesterol pathway components, such as ABCG1 and SREBP-2, could offer promising therapeutic strategies for mitigating ZIKV-induced ocular complications. Through the innovative research team that Dr. Kumar has established, they are at the forefront of developing breakthroughs that will play a vital role in therapeutic interventions in eye abnormalities caused by the Zika virus.

[…] The World Health Organization has suggested that priority should be to develop inactivated vaccines and other nonlive vaccines, which are safe to use in pregnant women. […] As of March 2016, 18 companies and institutions were developing vaccines against Zika, but they state a vaccine is unlikely to be widely available for about 10 years. […] In June 2016, the FDA granted the first approval for a human clinical trial for a Zika vaccine.

    In March 2017, a DNA vaccine was approved for phase-2 clinical trials. This vaccine consists of a small, circular piece of DNA, known as a plasmid, that expresses the genes for the Zika virus envelope proteins. As the vaccine does not contain the full sequence of the virus, it cannot cause infection. […] As of April 2017, both subunit and inactivated vaccines have entered clinical trials. However, like vaccines for other arboviruses, it is difficult to counteract an epidemic of this virus due to how it can appear sporadically and unpredictably.

[…] ZIKV-LAV infection in human GBM cells leads to both apoptotic and lytic cell death pathwaysparticularly pyroptosisduring late infection. […] ZIKV-LAV strains, particularly DN-1, exhibited potent oncolytic activity in human glioblastoma multiforme (GBM) cells without productively infecting non-cancer cells, such as terminally differentiated human neurons and primary endothelia. […] The reduced neurotropism also enhances cancer selectivity of ZIKV-LAV and, consequently, affords wider therapeutic window compared to wild-type ZIKV.

    While no specific treatment exists, paracetamol (acetaminophen) and rest may help with the symptoms. […] Treatment of Zika includes getting plenty of rest, drinking a lot of fluids to stay hydrated, and over-the-counter medicines such as acetaminophen to relieve fever and pain. It is not recommended to take aspirin or other non-steroidal anti-inflammatory drugs until after dengue infection is ruled out. […] The World Health Organization has suggested that priority should be to develop inactivated vaccines and other nonlive vaccines, which are safe to use in pregnant women. […] As of March 2016, 18 companies and institutions were developing vaccines against Zika, but they state a vaccine is unlikely to be widely available for about 10 years. […] In June 2016, the FDA granted the first approval for a human clinical trial for a Zika vaccine.

    In March 2017, a DNA vaccine was approved for phase-2 clinical trials. This vaccine consists of a small, circular piece of DNA, known as a plasmid, that expresses the genes for the Zika virus envelope proteins. As the vaccine does not contain the full sequence of the virus, it cannot cause infection. […] As of April 2017, both subunit and inactivated vaccines have entered clinical trials. However, like vaccines for other arboviruses, it is difficult to counteract an epidemic of this virus due to how it can appear sporadically and unpredictably.

    There is no anti-viral treatment and no vaccine to prevent from getting Zika at this time, though researchers are working hard to develop a vaccine against Zika. […] The Centers for Disease Control and Prevention is asking all pregnant women to consider postponing travel to areas with Zika transmission. If you must travel, talk to your doctor and strictly follow steps to prevent mosquito bites. Women trying to become pregnant should speak with their doctors before traveling. […] Without an existing cure or vaccine, prevention and preparedness are key to combating the spread of Zika.

    To protect yourself from the Zika virus while traveling to India, particularly in places where it has been detected, use the same precautions as for dengue illness, but with some added considerations. Precautions for Zika virus include the following: Mosquito protection you can apply N, N-diethyl-meta-toluamide, picaridin, and lemon eucalyptus oil to exposed skin. Wear long-sleeved shirts, long pants, socks, and hats to protect your skin as much as possible. […] Additional steps for Zika are to use condoms or abstain from sex, as Zika can be transmitted sexually. Women who are pregnant or planning to become pregnant should avoid travel to areas with Zika outbreaks, as the virus can cause severe birth defects. […] Symptoms of Zika infection include fever, rash, joint pain, conjunctivitis, and other general symptoms like headache, muscle pain, and malaise. Potential risks include birth defects and neurological complications.
