Przewlekły katar u niemowląt
Diagnostyka i diagnoza

Przeziębienie u niemowląt, będące jedną z najczęstszych infekcji wirusowych, manifestuje się typowymi objawami takimi jak wyciek z nosa (początkowo przejrzysty, później żółty lub zielony), przekrwienie błony śluzowej nosa, kaszel, kichanie, nieznacznie podwyższona temperatura do 38°C, zmniejszony apetyt, rozdrażnienie oraz trudności w karmieniu z powodu niedrożności nosa. Diagnostyka opiera się głównie na badaniu fizykalnym i wywiadzie, z oceną stanu błon śluzowych, węzłów chłonnych szyi, drożności dróg oddechowych oraz osłuchaniu płuc i badaniu otoskopowym w celu wykluczenia powikłań, takich jak zapalenie ucha środkowego. Wskazane jest różnicowanie z innymi infekcjami, w tym COVID-19, grypą, RSV, krztuścem, zapaleniem krtani, oskrzelików, płuc, ucha środkowego, zatok oraz alergiami. Badania dodatkowe (wymaz z nosa, badania krwi, RTG klatki piersiowej) są zarezerwowane dla przypadków nietypowych, ciężkich lub podejrzenia powikłań.

Diagnostyka przewlekłego kataru u niemowląt

Przeziębienie (przewlekły katar) jest jedną z najczęstszych chorób infekcyjnych u niemowląt. W pierwszym roku życia dzieci mogą przechodzić nawet 8-10 epizodów przeziębienia, szczególnie jeśli uczęszczają do żłobka lub mają starsze rodzeństwo w wieku szkolnym. Prawidłowa diagnostyka przewlekłego kataru u niemowląt jest kluczowa, aby odróżnić go od poważniejszych chorób, które mogą wymagać specjalistycznego leczenia.123

Rozpoznanie kliniczne

Rozpoznanie przewlekłego kataru u niemowląt opiera się głównie na objawach klinicznych i badaniu fizykalnym. Lekarz zazwyczaj nie potrzebuje przeprowadzać specjalistycznych badań diagnostycznych, aby potwierdzić przeziębienie u dziecka. Podczas badania pediatra zwraca uwagę na typowe objawy, które najczęściej pojawiają się 1-3 dni po kontakcie z wirusem i mogą utrzymywać się przez około 7-14 dni.123

Podstawowe objawy, na które zwraca uwagę lekarz podczas diagnozowania przeziębienia u niemowląt, to:123

  • Wyciek z nosa (początkowo przejrzysty, później może gęstnieć i zmieniać kolor na żółty lub zielony)
  • Przekrwienie błony śluzowej nosa (obrzęk)
  • Kaszel
  • Kichanie
  • Nieznacznie podwyższona temperatura ciała (do 38°C)
  • Zmniejszony apetyt
  • Rozdrażnienie
  • Problemy ze snem
  • Trudności w karmieniu z powodu niedrożności nosa
  • Nieznaczne powiększenie węzłów chłonnych szyi

12

Podczas badania fizykalnego lekarz może również ocenić:12

  • Stan błony śluzowej nosa i gardła (przekrwienie, obrzęk)
  • Węzły chłonne szyi pod kątem powiększenia
  • Drożność dróg oddechowych
  • Osłuchowo płuca w celu wykluczenia zmian osłuchowych
  • Uszy pod kątem potencjalnego zapalenia ucha środkowego (częstego powikłania przeziębienia)

Diagnostyka różnicowa

Objawy przeziębienia u niemowląt mogą przypominać inne choroby, dlatego istotna jest dokładna diagnostyka różnicowa. Lekarz musi wykluczyć:123

  • Infekcję COVID-19 – która u dzieci może przebiegać bezobjawowo lub z łagodnymi objawami przypominającymi przeziębienie
  • Grypę – charakteryzującą się wyższą gorączką i nagłym początkiem
  • Infekcję RSV (syncytialny wirus oddechowy) – szczególnie niebezpieczny dla niemowląt
  • Krztusiec (koklusz) – charakteryzujący się napadowym kaszlem
  • Zapalenie krtani (krup) – charakteryzujące się „szczekającym” kaszlem
  • Zapalenie oskrzelików – występuje świszczący oddech
  • Zapalenie płuc – charakteryzujące się trudnościami w oddychaniu i wysoką gorączką
  • Zapalenie ucha środkowego – objawiające się bólem ucha i rozdrażnieniem
  • Zapalenie zatok – jeśli objawy utrzymują się ponad 10 dni
  • Alergie – jeśli objawy pojawiają się regularnie w określonych porach roku lub po ekspozycji na alergeny

1234

Badania dodatkowe

W większości przypadków przeziębień u niemowląt badania laboratoryjne i obrazowe nie są konieczne. Jednak w niektórych sytuacjach, zwłaszcza gdy lekarz podejrzewa inne schorzenie lub komplikacje, może zlecić:123

  • Wymaz z nosa – w celu identyfikacji wirusa, np. testu na COVID-19, grypę lub RSV
  • Badania krwi – w przypadku podejrzenia infekcji bakteryjnej
  • Zdjęcie rentgenowskie klatki piersiowej – jeśli podejrzewa się zapalenie płuc lub inne schorzenia dolnych dróg oddechowych
  • Badanie otoskopowe – w przypadku podejrzenia zapalenia ucha środkowego

Warto podkreślić, że choć istnieje ponad 200 różnych wirusów mogących wywoływać przeziębienie (z najczęstszym rhinowirusem), w codziennej praktyce klinicznej rzadko wykonuje się izolację patogenu, ponieważ zazwyczaj nie wpływa to na sposób leczenia.123

Szczególne zalecenia diagnostyczne dla różnych grup wiekowych

Niemowlęta poniżej 3 miesiąca życia

Każde objawy przeziębienia u niemowląt poniżej 3 miesiąca życia wymagają natychmiastowej konsultacji lekarskiej. W tej grupie wiekowej przeziębienie może szybko przekształcić się w poważniejsze schorzenie, a układ odpornościowy noworodka jest jeszcze niedojrzały.123

Szczególną uwagę należy zwrócić na:12

  • Gorączkę powyżej 38°C u niemowląt poniżej 3 miesiąca życia – wymaga natychmiastowej konsultacji lekarskiej
  • Zmniejszony apetyt lub odmowę karmienia
  • Senność lub trudności z wybudzeniem
  • Zmniejszoną ilość mokrych pieluch (mniej niż 3-4 mokre pieluchy w ciągu 24 godzin)
  • Trudności w oddychaniu

Niemowlęta powyżej 3 miesiąca życia

U niemowląt powyżej 3 miesiąca życia przeziębienie często można bezpiecznie leczyć w domu, jednak należy skontaktować się z lekarzem, jeśli pojawią się następujące objawy:123

  • Gorączka powyżej 39°C
  • Gorączka utrzymująca się dłużej niż 3 dni
  • Objawy nieustępujące po 7-10 dniach
  • Objawy nasilające się zamiast ustępować
  • Trudności w oddychaniu lub przyspieszony oddech
  • Dziecko wydaje się być bardzo chore, jest wyjątkowo rozdrażnione lub senne
  • Problemy z przyjmowaniem płynów
  • Ból ucha lub ciągnięcie za uszy
  • Gęsta, zielona wydzielina z nosa utrzymująca się przez kilka dni
  • Kaszel utrzymujący się dłużej niż 3 tygodnie

Objawy alarmowe wymagające natychmiastowej konsultacji

Istnieją objawy, które wymagają natychmiastowej pomocy medycznej, niezależnie od wieku dziecka:123

  • Trudności w oddychaniu – widoczne wciąganie międzyżebrzy, ruch skrzydełek nosa, sinienie wokół ust
  • Kaszel z wymiotami lub zmieniający kolor skóry dziecka
  • Kaszel z odkrztuszaniem plwociny podbarwionej krwią
  • Sinica (niebieskawe zabarwienie) wokół ust lub na paznokciach
  • Znaczna apatia – dziecko nie reaguje na bodźce lub jest trudne do wybudzenia
  • Sztywność karku lub światłowstręt
  • Silny ból głowy
  • Odmowa przyjmowania płynów przez dłuższy czas
  • Znacznie zmniejszona ilość mokrych pieluch (oznaka odwodnienia)
  • Wysokie, uporczywe gorączki powyżej 40°C
  • Wysypka z towarzyszącą gorączką
  • Przedłużające się wymioty

Wyzwania diagnostyczne

Diagnostyka u dzieci, które nie potrafią komunikować objawów

Diagnozowanie przeziębienia u niemowląt może być szczególnie trudne, ponieważ nie potrafią one komunikować swoich objawów. Lekarz musi polegać na obserwacji, badaniu fizykalnym i informacjach dostarczonych przez rodziców.12

Rodzice powinni zwrócić uwagę na subtelne zmiany w zachowaniu dziecka, takie jak:1

  • Brak zainteresowania karmieniem (może wskazywać na ból gardła)
  • Częstsze wybudzanie się w nocy (może być spowodowane niedrożnością nosa)
  • Ogólny niepokój lub rozdrażnienie
  • Zmiana w częstości oddechów

Rozróżnienie między przeziębieniem a COVID-19

Infekcja COVID-19 u dzieci często przebiega bezobjawowo lub z łagodnymi objawami przypominającymi przeziębienie, co utrudnia rozróżnienie tych dwóch chorób na podstawie samych objawów klinicznych. Dokładna diagnoza wymaga wykonania testu na obecność wirusa SARS-CoV-2.123

Objawy COVID-19 u niemowląt mogą obejmować gorączkę, kaszel, katar, ale również objawy ze strony przewodu pokarmowego, takie jak biegunka czy wymioty. Okres inkubacji COVID-19 (4-6 dni, do 14 dni) jest zazwyczaj dłuższy niż w przypadku przeziębienia (1-3 dni).1

Podejście do diagnozy u niemowląt z nawracającymi przeziębieniami

Niemowlęta i małe dzieci mogą przechodzić nawet 6-8 przeziębień rocznie, co oznacza, że mogą wydawać się ciągle przeziębione, szczególnie w sezonie jesienno-zimowym. Jest to normalne i związane z rozwijającym się układem odpornościowym.12

W przypadku niemowląt z często nawracającymi przeziębieniami lekarz może rozważyć:12

  • Dokładniejszą ocenę pod kątem alergii – szczególnie jeśli objawy pojawiają się regularnie lub są związane z określonymi czynnikami
  • Badania w kierunku niedoborów odporności – w przypadku nietypowo częstych lub ciężkich infekcji
  • Ocenę środowiska domowego – obecność dymu papierosowego lub innych zanieczyszczeń
  • Ocenę kontaktu z innymi dziećmi – np. w żłobku

Podsumowanie diagnostyki

Diagnostyka przewlekłego kataru u niemowląt opiera się głównie na:123

  • Wywiadzie medycznym – początek objawów, czas trwania, nasilenie, kontakt z chorymi osobami
  • Badaniu fizykalnym – ocena stanu błon śluzowych nosa i gardła, węzłów chłonnych, osłuchiwanie płuc
  • Obserwacji charakterystycznych objawów – katar, kaszel, przekrwienie błony śluzowej nosa
  • Wykluczeniu poważniejszych schorzeń – poprzez badania dodatkowe w razie potrzeby

Badania diagnostyczne są zazwyczaj zarezerwowane dla przypadków, w których objawy są nietypowe, bardzo nasilone, trwają dłużej niż zwykle lub występują u niemowląt poniżej 3 miesiąca życia.12

Wczesna i prawidłowa diagnoza ma kluczowe znaczenie, aby odróżnić nieszkodliwe przeziębienie od potencjalnie poważniejszych chorób, które mogą wymagać specjalistycznego leczenia. Rodzice powinni zawsze konsultować się z lekarzem, jeśli mają wątpliwości co do stanu zdrowia swojego dziecka, szczególnie w przypadku bardzo małych niemowląt.12

    https://www.childrens.com/health-wellness/common-cold-in-babies
    There’s nothing common about a cold when a newborn or infant has one. The congestion, coughing and low-grade fever that can accompany a cold is enough to make even the most seasoned parents worry. Babies will have anywhere from eight to 10 colds by the time they turn 2 years old. As a parent, you may feel more comfortable and confident when you’re able to quickly recognize the signs of a common cold and know which remedies help ease symptoms. […] Signs of a common cold in babies are mostly the same as they are in adults. Symptoms can include a runny nose, nasal congestion, cough and fever. However, symptoms are different for each child. […] „Babies may not be able to tell their parents they’re sick, but they show other signs that something is not quite right,” says Michael Lee, M.D., Pediatrician at Children’s Health and Professor at UT Southwestern. „A lack of interest in feeding may be a sign of a sore throat; more frequent waking at night may signal congestion. Parents can take note of these signs, along with the more traditional symptoms, to start to recognize when their child is getting a cold.”

    The symptoms of a cold are usually worst during the first 10 days. However, some children continue to have a runny nose, congestion, and a cough beyond 10 days. In addition, it is not unusual for a child to develop a second cold as the symptoms of the first cold are resolving; this can make it seem as if the child has a single cold that lasts for weeks or even months, especially during the fall and winter. This is not a cause for concern, unless the child has any of the more serious symptoms, discussed below. […] COVID-19 infection in children is frequently either asymptomatic or results in a mild cold with fever and a cough (although runny nose, abdominal pain, vomiting, or other symptoms may occur). Infection caused by COVID-19 typically begins four to six days after exposure but may occur as long as 14 days after exposure. Severe infection, hospitalization, and death are less common in children than adults.

    There are signs or symptoms of an ear infection (pain, ear pulling, fussiness). […] SUMMARY […] The common cold is a group of symptoms caused by a number of different viruses, including SARS-CoV-2, the virus that causes COVID-19. Children under six years average six to eight colds per year (up to one per month, September through April), with symptoms lasting an average of 14 days. This means that a child could be ill with intermittent cold symptoms for nearly half of the days in this time period, without cause for concern. […] Colds are most contagious during the first two to four days. People with colds typically carry the cold virus on their hands, where it is capable of infecting another person for at least two hours. Some cold viruses can live on surfaces (such as countertops, door handles, or toys) for as long as one day. Droplets containing viral particles can be exhaled into the air by breathing, coughing, or sneezing.

    Caregivers may give acetaminophen (sample brand name: Tylenol) to treat a child (older than three months) who is uncomfortable because of fever during the first few days of a cold. Ibuprofen (sample brand names: Advil, Motrin) can be given to children older than six months. Aspirin should not be given to any child under age 18 years. There is no benefit of these medications if the child is comfortable. Caregivers should speak with their child’s health care provider about when and how to treat fever. […] Antibiotics – Antibiotics are not effective in treating colds. They are necessary only if the cold is complicated by a bacterial infection, like an ear infection, pneumonia, or sinusitis. Caregivers who think their child has developed one of these infections should contact their child’s health care provider.
