Trądzik noworodkowy
Epidemiologia

Trądzik noworodkowy (acne neonatorum) dotyka około 4,5-20% noworodków, pojawiając się zwykle między 2. a 4. tygodniem życia, choć może wystąpić już przy urodzeniu lub w ciągu pierwszych 6 tygodni. Charakteryzuje się drobnymi czerwonymi lub białymi grudkami na twarzy, zwłaszcza na policzkach, nosie i czole, i ustępuje samoistnie w ciągu 1-3 miesięcy bez blizn. W odróżnieniu od trądziku niemowlęcego, który pojawia się po 6 tygodniu życia (najczęściej między 3 a 6 miesiącem), dotyczy mniej niż 2% dzieci, może utrzymywać się do 1-2 lat i prowadzić do blizn. Obie formy wykazują predylekcję do płci męskiej, co sugeruje udział hormonów płciowych w patogenezie. Epidemiologicznie trądzik noworodkowy częściej występuje u noworodków urodzonych o czasie (37-40 tydzień ciąży) niż u wcześniaków.

Epidemiologia trądziku noworodkowego

Trądzik noworodkowy (acne neonatorum) jest stosunkowo częstą dermatologiczną przypadłością wieku noworodkowego, dotykającą około 20% noworodków. Dane epidemiologiczne wskazują na znaczne zróżnicowanie w częstotliwości występowania – różne badania podają przedział od 4,5% do 20% noworodków dotkniętych tym schorzeniem.123 Trądzik noworodkowy charakteryzuje się obecnością drobnych czerwonych lub białych grudek zlokalizowanych głównie na twarzy dziecka, ze szczególnym nasileniem na policzkach, nosie i czole.45

Występowanie czasowe

Trądzik noworodkowy zazwyczaj pojawia się około 2-4 tygodnia życia, choć może wystąpić w dowolnym momencie w pierwszych 6 tygodniach, a w niektórych przypadkach jest obecny już w momencie narodzin.67 Charakterystyczne jest, że trądzik noworodkowy ustępuje samoistnie w ciągu 1-3 miesięcy bez pozostawiania blizn.89

Różnice między trądzikiem noworodkowym a niemowlęcym

Istotne jest odróżnienie trądziku noworodkowego od trądziku niemowlęcego (infantile acne), który pojawia się po 6 tygodniu życia, najczęściej między 3 a 6 miesiącem, i dotyczy mniej niż 2% dzieci.1011 W przeciwieństwie do trądziku noworodkowego, trądzik niemowlęcy może utrzymywać się przez 1-2 lata i zwiększa ryzyko wystąpienia oraz nasilenia trądziku w okresie dojrzewania.12 Co istotne, trądzik niemowlęcy może prowadzić do powstawania blizn, czego nie obserwuje się w przypadku trądziku noworodkowego.13

Zróżnicowanie płciowe

Zarówno trądzik noworodkowy, jak i niemowlęcy wykazują wyraźną predylekcję do płci męskiej. W przypadku trądziku niemowlęcego dysproporcja ta jest jeszcze bardziej widoczna.141516 Chłopcy są dotknięci tym schorzeniem częściej niż dziewczynki, co może sugerować rolę hormonów płciowych w patogenezie tej choroby.17

Dane z badań epidemiologicznych

Według danych pochodzących z populacji pediatrycznej Stanów Zjednoczonych z lat 2000-2010, około 9,2 miliona ambulatoryjnych wizyt lekarskich rocznie dotyczyło trądziku u dzieci, przy czym trądzik noworodkowy i niemowlęcy stanowiły łącznie około 3% wszystkich przypadków (276 000 wizyt).1819

Dane epidemiologiczne sugerują również, że trądzik noworodkowy częściej występuje u dzieci urodzonych o czasie (37-40 tydzień ciąży) niż u wcześniaków.20

Nadzór i diagnostyka

Diagnoza trądziku noworodkowego jest zazwyczaj stawiana przez położne lub pediatrów na podstawie charakterystycznego obrazu klinicznego. W większości przypadków nie są konieczne żadne specjalistyczne badania.21 Jednak w przypadkach, gdy trądzik jest nasilony, utrzymuje się dłużej niż 3 miesiące lub towarzyszą mu inne objawy, zalecana jest konsultacja ze specjalistą – dermatologiem dziecięcym lub endokrynologiem.2223

Przypadki trądziku niemowlęcego, które są ciężkie i długotrwałe, mogą wymagać bardziej szczegółowej diagnostyki w kierunku zaburzeń endokrynologicznych. Należy jednak podkreślić, że ryzyko prawdziwego przedwczesnego dojrzewania u niemowląt i dzieci z trądzikiem pospolitym, ale bez innych objawów wirylizacji, jest bardzo niskie.24 Nawet w takich przypadkach dodatkowe badania laboratoryjne i konsultacje specjalistyczne mogą być uznane za zbędne i powodujące niepotrzebny niepokój rodziców.25

Kontrowersje w klasyfikacji

Warto zaznaczyć, że istnieją pewne kontrowersje dotyczące klasyfikacji i rozpoznawania trądziku noworodkowego. Niektórzy badacze sugerują, że rzeczywista częstość występowania może być przeszacowana ze względu na mylenie trądziku noworodkowego z innymi podobnymi wysypkami, takimi jak neonatal cephalic pustulosis, które nie występują z zaskórnikami.2627

Relacja między trądzikiem noworodkowym a neonatal cephalic pustulosis pozostaje przedmiotem dyskusji – niektórzy eksperci uznają je za dwie różne jednostki chorobowe, podczas gdy inni nie wyróżniają ich jako odrębnych schorzeń.28

Znaczenie kliniczne trądziku noworodkowego

Kliniczne znaczenie trądziku noworodkowego polega na konieczności odróżnienia go od chorób zakaźnych, wykluczenia wirylizacji jako przyczyny leżącej u jego podłoża oraz potencjalnych implikacji dotyczących możliwości wystąpienia ciężkiego trądziku w okresie dojrzewania.29

Należy również odróżnić trądzik noworodkowy od trądziku wywołanego stosowaniem olejków i maści (acne venenata) oraz od wysypek trądzikopodobnych wywołanych przez leki przyjmowane przez matkę, takie jak hydantoina (zespół płodowy hydantoiny) i lit.30

Nadzór w przypadkach szczególnych

Szczególnej uwagi wymagają przypadki ciężkiego, uporczywego trądziku noworodkowego z towarzyszącymi innymi objawami hiperandrogenizmu, gdyż mogą one wymagać diagnostyki w kierunku hiperplazji kory nadnerczy, guzów wirylizujących lub innych endokrynopatii.31

Warto również nadmienić, że każdy przypadek trądziku pojawiającego się w okresie średniego dzieciństwa (od 1 do 7 roku życia) powinien być badany pod kątem hiperandrogenizmu.32

Nadzór nad pacjentami z trądzikiem noworodkowym zazwyczaj nie wymaga specjalnego postępowania, gdyż schorzenie to ma charakter samoograniczający się. Rodzice powinni być poinformowani, że trądzik noworodkowy jest łagodny, samoograniczający się i zazwyczaj ustępuje samoistnie bez pozostawienia blizn w ciągu około 1-3 miesięcy.33

Podsumowując, trądzik noworodkowy jest częstym, przejściowym schorzeniem skórnym, dotykającym około 20% noworodków, z przewagą występowania u chłopców. Jego rozpoznanie opiera się głównie na obrazie klinicznym, a w większości przypadków nie wymaga specjalistycznego leczenia, gdyż ustępuje samoistnie w ciągu kilku tygodni do kilku miesięcy bez pozostawiania blizn.3435

    https://www.verywellhealth.com/baby-acne-8748697
    Baby acne (neonatal acne) is a common skin condition affecting babies’ faces and bodies. It causes tiny red bumps on the skin in the first few months of life. This condition affects about 20% of newborns. […] Baby acne usually occurs around 2 weeks of age. […] Most cases of baby acne resolve after 6 weeks of age. […] Baby acne occurs when a baby’s skin pores become clogged. Clogged pores can develop into pimples. […] Babies experience hormonal changes after birth that may increase the amount of oil (sebum) on the skin, which raises the risk of acne.

    Acne may present in neonates, infants, and small children. Neonatal and infantile acne vulgaris are not considered to be rare. […] Acne neonatorum occurs in up to 20% of newborns. The clinical importance of neonatal acne lies in its differentiation from infectious diseases, the exclusion of virilization as its underlying cause, and the possible implication of severe acne in adolescence. […] Neonatal acne also must be distinguished from acne that is induced by application of topical oils and ointments (acne venenata) and from acneform eruptions induced by acnegenic maternal medications such as hydantoin (fetal hydantoin syndrome) and lithium. […] Both maternal and neonatal androgens have been implicated in the stimulation of sebaceous glands in neonatal acne. […] The neonatal adrenal gland produces high levels of dehydroepiandrosterone, which stimulate sebaceous glands until around 1 year of age when dehydroepiandrosterone levels drop off as a consequence of involution of the neonatal adrenal gland.

    Baby acne, also known as infantile acne and neonatal acne, is a very common condition in newborns and infants. […] The condition can be present at birth, but in most cases it appears after a few weeks and peaks at around 2 months of age. […] Baby acne is characterised by small whiteheads surrounded by reddish skin that appear on the nose, cheeks and surrounding skin. […] Baby acne normally clears up after a few weeks so treatment isn’t often necessary. […] If your infant’s acne doesn’t clear up after 3 months you should seek advice from a doctor. […] Baby acne is a skin condition common amongst newborn babies and infants. […] Some children are born with it, but in most cases the condition appears after several weeks. […] Baby acne typically shows up on the nose, cheeks and temples of the child, but it can also be present on the forehead, chin and back.

    About 20% of newborns have a type of acne called neonatal acne. You’ll usually see it at about 2 weeks of age. However, it can develop any time before 6 weeks of age. Sometimes, a baby is born with acne. […] Neonatal acne is generally nothing to worry about. It rarely causes a scar and tends to go away on its own in a few weeks to months. […] When acne develops after 6 weeks of age, it’s called infantile acne. This type of acne is likely to begin between 3 and 6 months of age. […] If your baby develops acne after 6 weeks of age, you’ll want to see a board-certified dermatologist or pediatric dermatologist. This can be helpful for several reasons. […] While a dermatologist should examine a child who develops acne after 6 weeks of age, this type of acne often clears on its own. Clearing usually takes about 6 months to 1 year. Some children, however, have acne for a longer time. It’s possible for acne to continue through the teen years. […] A dermatologist can tell you whether you need to treat it. When acne requires treatment, you can rely on a dermatologist’s expertise to treat your baby safely.

    https://pmc.ncbi.nlm.nih.gov/articles/PMC5135542/
    Pediatric acne can be divided into five subgroups: neonatal, infantile, midchildhood, preadolescent and adolescent. […] Infantile acne has a similar lesion distribution and male predominance but includes comedones, nodules and cysts. In rare instances in which infantile acne is severe and persistent, or when additional signs of virilization are noted, underlying endocrinopathies must be considered. […] It presents later (age 316 mo) and is much less common, affecting less than 2% of children. […] Infantile acne may persist for one to two years and has been linked to an increased incidence and severity of adolescent acne. […] All cases of acne presenting in midchildhood (age one to seven years) should be investigated for hyperandrogenism. […] Unlike neonatal acne, infantile acne can result in scarring. The risk of scarring is difficult to estimate but increases with severity of acne and in patients with darker skin. Early and effective treatment of substantial infantile acne can reduce that risk.

    Neonatal and infantile acne are rare pediatric conditions. […] Compared to other types of acne there is a relative paucity of data on their pathogenesis and treatment. […] Current recommendations are mostly based on retrospective studies and case series. […] Androgen imbalance caused by maternal steroids in neonatal cases and endogenous secretion in infants is believed to be the primary cause of these forms of pediatric acne. […] Neonatal acne occurs in the first 6 weeks of life and affects about 20% of newborns. […] The pathomechanism of acne formation in this age group has not been fully explained. […] Neonatal acne subsides spontaneously within 1 to 3 months and does not require pharmacological treatment. […] Infantile acne occurs primarily between 6 weeks and 12 months of age and similarly to neonatal acne male predominance is observed. […] Contrary to the neonatal acne, this form of acne can leave scars, which prompts early treatment, especially in more severe cases. […] As with the neonatal acne, it is believed that the infantile acne is induced by androgens secreted by the adrenal cortex in both sexes.

    Acne neonatorum usually resolves within four months without scarring. […] Acne neonatorum occurs in up to 20 percent of newborns. […] Neonatal acne is thought to result from stimulation of sebaceous glands by maternal or infant androgens. […] Severe, unrelenting neonatal acne accompanied by other signs of hyperandrogenism should prompt an investigation for adrenal cortical hyperplasia, virilizing tumors, or underlying endocrinopathies.

    Pediatric acne can be divided into five subgroups: neonatal, infantile, midchildhood, preadolescent and adolescent. […] Infantile acne has a similar lesion distribution and male predominance but includes comedones, nodules and cysts. In rare instances in which infantile acne is severe and persistent, or when additional signs of virilization are noted, underlying endocrinopathies must be considered. […] It presents later (age 316 mo) and is much less common, affecting less than 2% of children. […] Infantile acne may persist for one to two years and has been linked to an increased incidence and severity of adolescent acne. […] All cases of acne presenting in midchildhood (age one to seven years) should be investigated for hyperandrogenism. […] Unlike neonatal acne, infantile acne can result in scarring. The risk of scarring is difficult to estimate but increases with severity of acne and in patients with darker skin. Early and effective treatment of substantial infantile acne can reduce that risk.

    The relationship between neonatal acne and neonatal cephalic pustulosis, which is characterized by papules and pustules without comedones, is controversial; some consider them to be 2 different entities, while others do not. […] Guardians should be reassured that neonatal acne is mild, self-limited, and generally resolves spontaneously without scarring in approximately 1 to 3 months. […] Most cases of infantile acne resolve by 4 or 5 years of age, but some remain active into puberty.

    Baby acne, or neonatal acne, is common and affects around 20 percent of newborns before they are 6 weeks old. […] Maternal hormones cause baby acne. Some babies are born with acne, while others develop it soon after birth. […] Baby acne typically starts before a baby is 6 weeks old. A rash or spot that appears after 6 weeks could be a result of something else. […] Baby acne typically goes away on its own within a few weeks. If it does not go away, or if it gets worse, a person may wish to consider seeing a doctor. […] Exposure to certain maternal hormones usually causes baby acne, which means that there is nothing specific that a caregiver can do to prevent it. […] For most babies, acne is only temporary and will go away on its own. Caregivers who are unsure or who are concerned that their baby’s acne is very severe should see a doctor.
