Rotawirus
Diagnostyka i diagnoza

Rotawirus stanowi główną etiologię ostrego zapalenia żołądka i jelit u dzieci poniżej 5 roku życia, powodując rocznie około 25 milionów wizyt klinicznych, 2 miliony hospitalizacji oraz 180 000-450 000 zgonów globalnie. Diagnostyka rotawirusowej infekcji opiera się przede wszystkim na badaniu klinicznym i wywiadzie, jednak potwierdzenie wymaga analizy próbek kału. Dostępne metody laboratoryjne obejmują testy immunoenzymatyczne (ELISA) o czułości i swoistości 90-95%, szybkie testy immunochromatograficzne (ICT) dające wynik w 10-15 minut, testy aglutynacji lateksowej oraz RT-PCR, uważany za złoty standard diagnostyczny ze względu na bardzo wysoką czułość i swoistość. Próbki kału powinny być pobierane jak najszybciej po wystąpieniu objawów i przechowywane w odpowiednich warunkach (schłodzone do 72 godzin lub zamrożone do 30 dni). Wynik pozytywny potwierdza obecność rotawirusa, ale nie wyklucza koinfekcji innymi patogenami, natomiast wynik negatywny nie eliminuje infekcji z powodu możliwości fałszywie ujemnych rezultatów.

Diagnostyka Rotawirusa

Rotawirus jest główną przyczyną ostrego zapalenia żołądka i jelit u dzieci na całym świecie. Każdego roku wirus ten odpowiada za około 25 milionów wizyt klinicznych, 2 miliony hospitalizacji i 180 000-450 000 zgonów u dzieci poniżej 5 roku życia na całym świecie.1 Rozpoznanie rotawirusowej infekcji ma kluczowe znaczenie dla prowadzenia odpowiedniego leczenia i zapobiegania rozprzestrzenianiu się wirusa w środowisku, zwłaszcza w warunkach szpitalnych i instytucjonalnych.

Diagnostyka kliniczna

Zapalenie żołądka i jelit wywołane przez rotawirusa nie może być klinicznie odróżnione od infekcji wywołanych przez inne patogeny jelitowe.12 Diagnoza rotawirusa jest zazwyczaj stawiana na podstawie objawów i badania fizykalnego.34 Lekarz może przeprowadzić wywiad dotyczący objawów dziecka, ich nasilenia oraz czynników, które je nasilają lub łagodzą.5

Ustalenie jednoznacznej diagnozy rotawirusa wymaga jednak badania próbek kału za pomocą dostępnych komercyjnie testów.6 Warto zaznaczyć, że badania laboratoryjne nie są rutynowo wykonywane u pacjentów z zapaleniem żołądka i jelit, ponieważ wyniki nie zmieniają postępowania klinicznego, które opiera się głównie na odpowiedniej terapii nawadniającej.17

Metody diagnostyki laboratoryjnej

Istnieje kilka metod laboratoryjnych służących do wykrywania rotawirusa w próbkach kału:

Testy wykrywające antygen

Immunoenzymatyczne testy (ELISA) są szeroko stosowane do wykrywania antygenu rotawirusa w próbkach kału. Większość tych testów charakteryzuje się wysoką czułością i swoistością (90-95%).8 Testy ELISA są skierowane na wykrywanie antygenu wspólnego dla wszystkich rotawirusów grupy A.9 Przykładami komercyjnych testów ELISA są RIDASCREEN Rotavirus, Premier Rotaclone, oraz KT-841 Fecal Rotavirus Antigen ELISA Kit.101112

Testy immunochromatograficzne (szybkie testy kasetkowe) umożliwiają uzyskanie wyników w ciągu 10-15 minut. Przykładami są RIDAQUICK Rotavirus, NADAL Rotavirus Test, oraz Bioline Rotavirus.131415 Szybkie testy immunochromatograficzne (ICT) działają podobnie do domowych testów ciążowych, dając wyniki w ciągu około 15 minut.16

Testy aglutynacji lateksowej są również stosowane do wykrywania rotawirusa w próbkach kału.917

Metody molekularne

Reakcja łańcuchowa polimerazy z odwrotną transkryptazą (RT-PCR) jest szeroko stosowana w laboratoriach badawczych do wykrywania genomu wirusa.8 Metoda ta dostarcza dane dotyczące genotypów VP7 i VP4, które stanowią podstawę binarnej klasyfikacji (odpowiednio typ G i P) szczepów rotawirusa.8 RT-PCR jest bardzo czułą metodą i może być wykonywany jako pojedynczy test lub w ramach paneli wielopatogenowych.1819

Ilościowy RT-PCR (qRT-PCR) pozwala na wykrywanie i ilościowe oznaczanie rotawirusów.20

Analiza sekwencyjna jest definitywną metodą potwierdzania genotypów rotawirusa.9 Szczepy można dalej charakteryzować poprzez sekwencjonowanie kwasów nukleinowych, jednak takie testy są zazwyczaj przeprowadzane tylko przez laboratoria zajmujące się badaniami nadzoru lub badaniami naukowymi.18

Inne metody diagnostyczne

Mikroskopia elektronowa jest wysoce specyficzna dla wykrywania rotawirusa, o czułości porównywalnej do testów immunoenzymatycznych.6 Pierwotnie diagnoza rotawirusa była stawiana właśnie przy użyciu mikroskopii elektronowej, z aglutynacją lub bez aglutynacji przez surowice immunologiczne.1

Elektroforeza w żelu poliakrylamidowym (PAGE) umożliwia wykrywanie segmentów dwuniciowego RNA rotawirusa w próbkach klinicznych poprzez ekstrakcję wirusowego RNA i analizę za pomocą elektroforezy w żelu poliakrylamidowym, a następnie barwienie srebrem.21 Obecność charakterystycznych wzorów elektroforetycznych jest od dawna uważana za diagnostyczną dla obecności poszczególnych rotawirusów.21

Izolacja wirusa jest wykorzystywana do potwierdzenia obecności wirusa, ale nie choroby.22

Wskazania do wykonania testów diagnostycznych

Chociaż diagnostyka laboratoryjna nie jest rutynowo wykonywana, istnieją sytuacje, w których testy na obecność rotawirusa mogą być wskazane:

  • Pacjenci z czerwonymi flagami dla biegunki
  • Pacjenci hospitalizowani, gdy rozważana jest kohorta
  • Wykluczenie alternatywnych diagnoz (np. bakteryjne zapalenie żołądka i jelit)
  • Diagnozowanie ognisk epidemicznych
  • Ciężkie, oporne przypadki infekcji, w których potrzebne jest potwierdzenie laboratoryjne diagnozy rotawirusa
  • Gdy może to skrócić długość pobytu w szpitalu lub pomóc uniknąć niepotrzebnych procedur

2317195

Pobieranie i przechowywanie próbek

Rotawirus jest wydalany w dużym stężeniu w kale dzieci z zapaleniem żołądka i jelit, dlatego próbka kału jest preferowaną próbką do diagnostyki.9 Próbki kału powinny być pobierane jak najszybciej po wystąpieniu objawów.24

Instrukcje dotyczące pobierania próbek:

  • Zebrać świeży kał w sterylnym, szczelnym pojemniku bez mediów, konserwantów lub jonów metali
  • W przypadku pacjentów wymagających stosowania pieluch, najpierw wyłożyć pieluchę czystym plastikiem, aby zapobiec absorpcji
  • Przenieść 5 g lub 5 ml próbki kału z pieluchy wyłożonej plastikiem do sterylnego pojemnika
  • Nie przesyłać samej pieluchy
  • Bezpiecznie zakręcić pojemnik

25

Stabilność próbki:

  • Temperatura pokojowa: Nieakceptowalna
  • Schłodzona: 72 godziny
  • Zamrożona: 30 dni

25

Interpretacja wyników

Wyniki testów na rotawirusa należy interpretować z ostrożnością:

  • Wynik pozytywny: Potwierdza obecność rotawirusa jako przyczyny biegunki, ale nie wyklucza obecności innych patogenicznych organizmów. Chociaż związek między rotawirusem a zapaleniem żołądka i jelit jest dobrze ustalony, możliwa jest koinfekcja patogenami bakteryjnymi lub pasożytniczymi.
  • Wynik negatywny: Nie wyklucza możliwości infekcji rotawirusem, ponieważ zbyt mała ilość wirusa lub nieodpowiednie czy niewłaściwe pobranie próbki może spowodować wynik fałszywie ujemny.

2426

Parametry laboratoryjne w diagnostyce rotawirusa

Oprócz testów bezpośrednio wykrywających rotawirusa, niektóre parametry hematologiczne i biochemiczne mogą pomóc w diagnozowaniu i odróżnianiu zapalenia żołądka i jelit wywołanego przez rotawirusa, szczególnie w środowiskach o ograniczonych zasobach:

  • Poziom WBC i limfocytów jest niższy w przypadkach rotawirusa w porównaniu z przypadkami negatywnymi
  • Poziomy AST i ALT są wyższe w przypadkach rotawirusa w porównaniu z przypadkami negatywnymi
  • Przypadki rotawirusa (ale nie adenowirusa) prezentują limfopenię
  • Hemoglobina, hematokryt i MCV są znacząco niższe w przypadkach rotawirusa
  • Podczas ostrej choroby można zaobserwować niewielki wzrost poziomu AST w surowicy bez dalszych oznak uszkodzenia wątroby, co wskazuje na uszkodzenie komórek nabłonkowych jelit

2728

Czułość i specyficzność testów

Różne testy diagnostyczne na rotawirusa wykazują różną czułość i specyficzność:

Test diagnostyczny Czułość Specyficzność Uwagi
Testy ELISA 90-95% 90-95% Powszechnie stosowane w diagnostyce
Bioline Rotavirus 94% (vs. RT-PCR) 98.3% (vs. RT-PCR) Test immunochromatograficzny
RIDASCREEN Rotavirus 95.7% 99.1% W porównaniu do 3 komercyjnych ELISA
Fecal Rotavirus Antigen Rapid Test Kit 75.5% 98.2% W porównaniu do jednostopniowego RT-PCR
RT-PCR Bardzo wysoka Bardzo wysoka Uważany za „złoty standard”

Znaczenie diagnostyki w praktyce klinicznej

Chociaż diagnostyka laboratoryjna rotawirusa nie jest rutynowo wykonywana, ponieważ leczenie opiera się głównie na odpowiedniej terapii nawadniającej, istnieją sytuacje, w których potwierdzenie diagnozy może być przydatne:

  • Przy diagnozowaniu ognisk epidemicznych, zwłaszcza w placówkach opieki zdrowotnej lub ośrodkach opieki długoterminowej
  • W ciężkich przypadkach wymagających hospitalizacji
  • W badaniach epidemiologicznych i nadzorze nad rotawirusem
  • Przy ocenie skuteczności szczepionek przeciwko rotawirusowi

173233

W większości przypadków, zwłaszcza w podstawowej opiece zdrowotnej, diagnoza rotawirusa jest stawiana klinicznie na podstawie objawów i badania fizykalnego, a leczenie koncentruje się na zapobieganiu odwodnieniu i leczeniu objawowym.434

Warto podkreślić, że szczepienie przeciwko rotawirusowi jest obecnie najlepszą ochroną przed infekcją. Od momentu wprowadzenia szczepionek przeciwko rotawirusowi do programów szczepień, zaobserwowano znaczny spadek zachorowań na rotawirusa u niemowląt i małych dzieci.3536

    Rotavirus is the leading cause of severe childhood gastroenteritis. Each year, rotavirus is responsible for about 25 million clinic visits, two million hospital admissions, and 180 000450 000 deaths in children under 5 years of age globally. […] Gastroenteritis caused by rotavirus cannot be clinically distinguished from that caused by other enteric pathogens; diagnosis requires testing of fecal specimens with commercially available assays. However, rotavirus is not routinely tested for in patients with gastroenteritis because the results do not alter clinical management, which relies mainly on appropriate rehydration therapy. […] Rotavirus can be detected in stool specimens from children with gastroenteritis by several techniques, including electron microscopy, polyacrylamide gel electrophoresis, antigen detection assays, reverse transcription polymerase chain reaction (RT-PCR), and virus isolation. Diagnosis of rotavirus was initially by electron microscopy, with and without agglutination by immune sera.

  • #4 What Is Rotavirus? Symptoms & Treatment
    https://my.clevelandclinic.org/health/diseases/8275-rotavirus
    If your child has signs of rotavirus, contact their healthcare provider. Providers can often diagnose rotavirus based on symptoms and a physical examination. In some cases, they may take a stool (poop) sample to test it for rotavirus. But this step usually isn’t necessary. […] If you do need to take a stool sample, your child’s provider will give you a sterile (germ-free) container. You collect some of your child’s stool in the container. A lab analyzes the stool for rotavirus. […] A virus causes rotavirus, not bacteria. So antibiotics won’t help your child feel better. The virus should clear on its own after about a week. The main rotavirus treatment is to keep your child hydrated. […] The best way to prevent rotavirus and protect the health of your family is to make sure they get one of the rotavirus vaccines.

    https://www.infectiousdiseaseadvisor.com/ddi/rotavirus/
    Rotavirus is a highly contagious infection that causes diarrhea and vomiting. Therefore, this article focuses on the risk factors, diagnosis, and treatment of rotavirus in young children. […] Clinicians evaluating a child who may have rotavirus infection should ask about the child’s symptoms, including their severity and what makes them improve or worsen. […] Most patients are diagnosed clinically, but for some, stool tests may be used to confirm diagnosis. The following laboratory techniques are used for the definitive diagnosis of rotavirus in stool samples: Electron microscopy; Gel electrophoresis; Antigen detection (such as enzyme-linked immunosorbent assays [ELISAs] and immunochromatographic assays); Reverse transcription polymerase chain reaction (RT-PCR); and Virus isolation. […] The rotavirus antigen can be found in fecal samples using RT-PCR and ELISAs. However, treatment for pathogens that cause gastroenteritis is primarily supportive, so a differential diagnosis is not always necessary. Testing is typically only indicated when it can decrease the length of a hospital stay or help to avoid unnecessary procedures.

    Purpose: The present study aimed to evaluate and estimate the additional and auxiliary diagnostic value of routine laboratory parameters in patients with acute diarrhea caused by rotavirus and adenovirus. […] Rotavirus diarrhea was diagnosed in 16.8% and adenovirus diarrhea in 3.2% of patients. […] Hematological and biochemical parameters may assist in diagnosing and distinguishing rotaviral and adenoviral gastroenteritis, especially in low-resource environments. […] The lymphocyte/monocyte ratio represents a better balance between lymphocytes and monocytes. […] Rotavirus (but not adenovirus-positive) cases presented with lymphopenia in our study. […] The other potential valid parameters to distinguish Rotavirus positive cases from negative ones were hemoglobin, hematocrit, and MCV parameters; in our study, they were significantly lower in RPAG than in RNAG.

    A slight increase in serum AST levels may be observed during acute illness without further signs of liver damage, indicating damage to intestinal epithelial cells in 15% of the cases. […] Our study supports the literature on the subject that CRP has no diagnostical or distinguishing value in acute viral gastroenteritis cases: the CRP levels were lower in APAG patients and were not statistically different in RPAG patients compared to the negative ones. […] The most remarkable outcomes of our study are as follow. We found that WBC and lymphocyte levels get lower in RPAG compared with the negative ones, AST and ALT levels get higher in RPAG compared with the negative ones; it may have an exhilarative value in Rotavirus diarrhea diagnosis.

    Rotavirus is the leading cause of morbidity and mortality due to acute gastroenteritis among children under five years globally. Early diagnosis of rotavirus infection minimizes its spread and helps to determine the appropriate management of diarrhea. The aim of this study was to evaluate the performance of EpiTuub Fecal Rotavirus Antigen Rapid Test Kit for the diagnosis of rotavirus infection among diarrheic children under five years in Ethiopian healthcare settings. […] The sensitivity, specificity, and predictive values of the rapid test kit were determined. Moreover, the agreement of the rapid test kit with one step RT-PCR was determined by kappa statistics and receiver operators curve (ROC) analysis was done to assess the overall diagnostic accuracy of the rapid test kit. Fecal Rotavirus Antigen Rapid Test Kit has shown a sensitivity of 75.5% and specificity of 98.2%.

    What laboratory diagnostic methods can I use to diagnose rotavirus? Which one should I choose according to the situation? How do I interpret the results? […] Each group of virus is different from each other and requires specific assays designed for them. […] Gross pathology […] Not diagnostic similar lesions can be found with other diseases especially coronavirus infections (transmissible gastroenteritis, porcine epidemic diarrhea, and porcine delta coronaviruses) […] Unable to differentiate between different groups of rotaviruses. […] Histopathology […] Confirm villus atrophy suggesting viral enteritis. […] Immunohistochemistry (IHC) […] Definitive diagnosis: can confirm presence of virus with associated lesions. […] Currently only available for Rotavirus A and Rotavirus C (not available for Rotavirus B).

    The samples to submit for rotavirus diagnosis are feces, intestinal tissue and content of a non-treated acutely infected pig. RT-PCR on those samples gives a quick results and is the most widely-used test. Genotyping of the isolated strain is also available to track the evolution of the virus. Immunofluorescence and immunohistochemistry can both be used to test epithelial cells for viral presence. Finally, ELISA tests are available to test for antigens but the results are of little interest since the viruses are ubiquitous. […] Rotavirus is one of the main forms of neonatal diarrhea including colibacillosis, clostridia infections, coronaviruses such as TGE and PED both of which cause higher mortality rates and vomiting-, and coccidiosis which targets piglets after their second week of life.

    This chapter provides general guidance for vaccine-preventable disease surveillance, describing the disease background/epidemiology, case investigation and reporting/notification, disease case definitions, and activities for enhancing surveillance, case investigation, and outbreak control for rotavirus. […] Definitive diagnosis of rotavirus gastroenteritis requires laboratory confirmation of infection. […] It is not possible to diagnose rotavirus infection by clinical presentation because the clinical features of rotavirus gastroenteritis do not differ from those of gastroenteritis caused by other pathogens. Confirmation of rotavirus infection by laboratory testing is necessary for reliable rotavirus surveillance and can be useful in clinical settings to avoid inappropriate use of antimicrobial therapy.

    Rotavirus must be notified by pathology services in writing within 5 days of diagnosis. […] Diagnosis may be made by rapid antigen detection of rotavirus in stool specimens. Strains may be further characterised by enzyme immunoassay or reverse transcriptase polymerase chain reaction. Stools for these tests should be collected in the acute phase of illness. […] Rotavirus vaccination was added to the National Immunisation Program schedule in July 2007. It is recommended that doses of oral vaccine are given at 2 and 4 months of age, or 2, 4 and 6 months of age, depending on the vaccine used. Completion of the vaccine course with the same brand of vaccine is preferred.

    These findings suggest that oral administration of human serum immunoglobulins may be beneficial in the treatment of hospitalized children with rotavirus disease. […] Most patients presenting to an outpatient clinic or the emergency department can be discharged home safely. […] Hospital admission may be beneficial to patients with signs or symptoms of dehydration, intractable vomiting, electrolyte disturbances, abdominal pain, ileus, renal failure, or pregnancy.

    Initial treatment for rotavirus infection should address the child’s dehydration. For patients with mild to moderate dehydration, oral rehydration is the first-line treatment. […] According to the WHO, a reduced-osmolarity solution is recommended because it is associated with a lower risk for hyponatremia. […] Vaccination against rotavirus is currently the best protection against infection. Four vaccines have been developed for rotavirus: RV5 vaccine (RotaTeq [Merck]); RV1 vaccine (Rotarix [GSK]); ROTAVAC (Bharat Biotech); and Rotasiil (Serum Institute of India).

    Rotavirus causes gastroenteritis. The symptoms include severe watery diarrhoea, usually with vomiting, fever, and stomach cramps. […] Infants and young children are most at risk of rotavirus disease, as they can become severely dehydrated and may require hospitalisation. The symptoms usually last from 3 to 8 days. […] Rotavirus is the most common cause of gastroenteritis in infants and very young children. […] A rotavirus vaccine was introduced to the national vaccination schedule for babies in 2013, alongside other routine childhood immunisations. […] The amount of rotavirus among infants has declined following use of the vaccine. […] Rotavirus: laboratory confirmed cases of rotavirus infections in England and Wales.
