Trądzik noworodkowy – Etiologia i przyczyny

Trądzik noworodkowy
Etiologia i przyczyny

Trądzik noworodkowy (acne neonatorum) dotyka około 20% noworodków, pojawiając się zwykle między 2. a 6. tygodniem życia. Etiologia jest wieloczynnikowa, z dominującą rolą hormonów matczynych, zwłaszcza androgenów przenikających przez łożysko, które stymulują nadprodukcję sebum przez gruczoły łojowe noworodka. U chłopców androgeny pochodzą zarówno z nadnerczy, jak i jąder, co tłumaczy wyższą częstość występowania. Alternatywna teoria wskazuje na reakcję zapalną na kolonizujące skórę drożdżaki Malassezia, które w warunkach zwiększonej produkcji sebum mogą wywoływać zmiany zapalne przypominające trądzik. Niedojrzałość strukturalna skóry noworodka, w tym cienka warstwa naskórka i nie w pełni ukształtowane pory, oraz niedojrzały układ immunologiczny skóry, również predysponują do rozwoju zmian trądzikowych. Predyspozycje genetyczne mogą zwiększać wrażliwość gruczołów łojowych na androgeny, jednak trądzik noworodkowy różni się patofizjologicznie od trądziku młodzieńczego.

Etiologia trądziku noworodkowego

Trądzik noworodkowy (łac. acne neonatorum) to powszechna dolegliwość skórna, która dotyka około 20% noworodków. Występuje zwykle w pierwszych tygodniach życia, najczęściej między 2. a 6. tygodniem, choć niektóre dzieci mogą urodzić się już z objawami trądziku.¹²³ Dokładna przyczyna trądziku noworodkowego nie została w pełni poznana, jednak istnieje kilka wiodących teorii dotyczących jego etiopatogenezy. Należy podkreślić, że trądzik noworodkowy różni się od trądziku występującego u nastolatków i dorosłych – nie jest powodowany przez te same bakterie i czynniki.⁴

Wpływ hormonów matczynych

Najczęściej wymienianą przyczyną trądziku noworodkowego jest wpływ hormonów matczynych, które przechodzą przez łożysko do krwioobiegu dziecka w okresie ciąży. Hormony androgenowe matki, przekazane dziecku pod koniec ciąży, mogą stymulować gruczoły łojowe noworodka, powodując nadprodukcję sebum i w konsekwencji powstanie zmian trądzikowych.⁵⁶ Te hormony, cyrkulujące w organizmie dziecka po porodzie, mogą czasowo pobudzać gruczoły łojowe, które w normalnych warunkach pozostają nieaktywne aż do okresu dojrzewania.⁷

U noworodków płci męskiej zarówno androgeny nadnerczowe, jak i jądrowe mogą przyczyniać się do powstawania trądziku, co tłumaczy większą częstość występowania tego schorzenia u chłopców.⁸⁹ W przypadku dziewczynek, źródłem androgenów są głównie nadnercza.¹⁰

Reakcja zapalna na drożdże skórne

Druga wiodąca teoria sugeruje, że trądzik noworodkowy może być wynikiem reakcji zapalnej na drożdżaki z rodzaju Malassezia, które kolonizują skórę noworodka. Drożdżaki te naturalnie występują na skórze, jednak u noworodków mogą wywoływać stan zapalny, który klinicznie przypomina trądzik.¹¹¹² Zdaniem niektórych dermatologów, to, co często nazywane jest „trądzikiem noworodkowym”, jest w rzeczywistości reakcją zapalną na nadmierny wzrost drożdżaków Malassezia, które rozwijają się na skórze noworodka po porodzie.¹³

Drożdżaki te mogą bujnie rozwijać się na skórze noworodka szczególnie w warunkach zwiększonej produkcji sebum, co prowadzi do stanu zapalnego manifestującego się jako neonatalny trądzik.¹⁴¹⁵ Według tej teorii, trądzik noworodkowy stanowi reakcję na kształtowanie się mikrobiomu skóry w pierwszych tygodniach życia.¹⁶

Niedojrzałość skóry noworodka

Skóra noworodka jest znacznie cieńsza i bardziej delikatna niż skóra starszych dzieci czy dorosłych. Ta niedojrzałość strukturalna może przyczyniać się do powstawania trądziku noworodkowego.¹⁷ Gruczoły łojowe noworodków mogą być fizjologicznie nadaktywne w okresie adaptacji do nowego, pozałonowego środowiska. Produkują one więcej sebum, co może prowadzić do zatykania porów i formowania się trądziku.¹⁸

Ponadto, pory skórne noworodka nie są w pełni ukształtowane po urodzeniu, co może zwiększać podatność na rozwój trądziku pod wpływem czynników drażniących ze środowiska zewnętrznego.¹⁹ Niedojrzały układ immunologiczny skóry może również odgrywać rolę w rozwoju stanu zapalnego prowadzącego do trądziku.²⁰

Czynniki genetyczne

Predyspozycja genetyczna może również odgrywać rolę w rozwoju trądziku noworodkowego. U niektórych niemowląt występuje genetycznie uwarunkowana zwiększona aktywność gruczołów łojowych w odpowiedzi na normalne poziomy krążących androgenów.⁵²¹ Jeśli rodzice mieli trądzik jako noworodki, niemowlęta lub nawet później w życiu, ich dziecko może być bardziej podatne na doświadczanie tymczasowych wykwitów trądzikowych.²²

Należy jednak zaznaczyć, że występowanie trądziku noworodkowego nie jest koniecznie związane z występowaniem trądziku w okresie dojrzewania czy dorosłości.²³ Trądzik noworodkowy i młodzieńczy mają odmienne podłoże patofizjologiczne.

Inne potencjalne czynniki wywołujące

Istnieje szereg dodatkowych czynników, które mogą przyczyniać się do rozwoju lub zaostrzenia trądziku noworodkowego:

Hormony w mleku matki – niektóre badania sugerują, że hormony przekazywane dziecku przez mleko matki mogą wpływać na rozwój trądziku.¹²⁴
Ślina i mleko – resztki mleka, śliny czy treści ulewanych pozostające na skórze dziecka mogą drażnić delikatną skórę i przyczyniać się do powstawania zmian trądzikowych.⁸²⁵
Produkty do pielęgnacji skóry – niektóre olejki, maści czy inne kosmetyki zawierające składniki oleiste mogą zatykać pory i nasilać objawy trądziku.²²⁶
Detergenty i tkaniny – silne detergenty, perfumy w środkach piorących oraz szorstkie tkaniny mogą podrażniać skórę noworodka i przyczyniać się do rozwoju trądziku.²⁷²⁸
Leki – niektóre leki przyjmowane przez matkę w okresie karmienia piersią mogą przenikać do mleka i wpływać na rozwój trądziku u dziecka.²⁷²⁹

Trądzik niemowlęcy – odmienne podłoże

Należy wyraźnie odróżnić trądzik noworodkowy (neonatal acne) od trądziku niemowlęcego (infantile acne). Trądzik niemowlęcy pojawia się później, zwykle między 3. a 6. miesiącem życia, i może utrzymywać się do 1-2 lat.³⁰³¹ W przeciwieństwie do trądziku noworodkowego, trądzik niemowlęcy może prowadzić do trwałych blizn.³²

Przyczyny trądziku niemowlęcego mogą być bardziej złożone i w rzadkich przypadkach mogą wskazywać na zaburzenia endokrynologiczne. Jeśli trądzik pojawia się po 6. tygodniu życia, szczególnie jeśli jest ciężki lub towarzyszą mu inne objawy maskulinizacji, należy rozważyć diagnostykę w kierunku chorób endokrynologicznych, takich jak:³³³⁴

Wrodzony przerost nadnerczy
Zespół Cushinga
Niedobór 21-hydroksylazy
Przedwczesne dojrzewanie płciowe
Guzy wydzielające androgeny
Przedwczesne adrenarche (wczesne dojrzewanie)

Podsumowanie przyczyn trądziku noworodkowego

Trądzik noworodkowy jest powszechną, przejściową dolegliwością skórną, która zwykle ustępuje samoistnie bez leczenia. Choć dokładna etiologia nie została w pełni poznana, główne teorie wskazują na wpływ hormonów matczynych, reakcję zapalną na drożdżaki Malassezia, niedojrzałość skóry noworodka oraz predyspozycje genetyczne jako główne czynniki sprawcze.³⁵³⁶

Warto podkreślić, że trądzik noworodkowy nie jest związany z higieną, alergiami czy dietą matki i zazwyczaj nie wymaga specjalistycznego leczenia. W przypadku utrzymywania się objawów powyżej 3-6 miesięcy lub jeśli trądzik pojawia się po 6. tygodniu życia, wskazana jest konsultacja z pediatrą lub dermatologiem dziecięcym w celu wykluczenia trądziku niemowlęcego lub innych zaburzeń hormonalnych.³⁷³⁸

#5 Infantile Acne – StatPearls – NCBI Bookshelf
https://www.ncbi.nlm.nih.gov/books/NBK541124/
The precise etiology of infantile acne has yet to be determined. Current theories include genetic predisposition and heightened sebaceous gland activity in response to normal levels of circulating androgens (adrenal androgens in female infants; both adrenal and testicular androgens in male infants). […] In rare cases, infantile acne can be a sign of an adrenocortical tumor, and there are case reports of Malassezia as a cause of infantile acne.
#6 Neonatal acne – Wikipedia
https://en.wikipedia.org/wiki/Neonatal_acne
Neonatal acne, also known as acne neonatorum, is a type of acne that develops in newborns, typically within the first six weeks of life. […] The main cause is not known for certain but it may be caused by maternal androgens transferred from the mother to the newborn from the placenta and androgens produced by the fetal adrenal gland and neonatal testicles that stimulate sebaceous glands to increase production of sebum. […] It is believed that maternal androgens passed to the infant through the placenta has a role in stimulating sebaceous glands leading to increased sebum production that causes comedone formation. […] Dehydroepiandrosterone (DHEA) produced from the fetal adrenal gland and androgen production from neonatal testicles may also stimulate sebum production from sebaceous glands.

https://www.happiestbaby.com/blogs/baby/baby-acne
Is that acne on your baby?! While pimples may be synonymous with teenagers, infants arent immune. In fact, about 20% of newborns have whats called neonatal acne, according to the American Academy of Dermatology (AAD). […] There are a few reasons little ones may develop baby acne, including […] Excess oil: Hormones from the placenta are still circulating in your babys system in the days and weeks following their birth, which may cause your babys skin to overproduce sebum. […] Inflammatory response: Its thought that baby acne is an inflammatory response to the high level of a specific type of yeast called Malassezia present on newborns skin. […] Sensitive skin: Babies have extra sensitive skin, so sometimes drool or spit up that lingers on the skin causes a baby breakout, too. […] Their sex: Experts note that baby boys tend to get more baby acne than baby girls. […] Endocrine abnormality: Children between the ages of 1 and 7 dont produce significant amounts of androgens (so-called male hormones), so toddler acne may be due to an endocrine abnormality that must be evaluated by a pediatric endocrinologist, who specializes in hormone issues.
#9 Acne in children
https://dermnetnz.org/topics/acne-in-children
Neonatal acne is thought to be a result of hyperactive sebaceous glands responding to neonatal androgens and maternal androgens that have crossed through the placenta. […] From birth to around 12 months of age, luteinising hormone levels are similar to those during puberty. In males, this results in increased testosterone production and may explain the higher incidence of acne in boys of this age compared to girls. […] Sebum production leads to increased colonisation of the hair follicles by the acne bacteria, P. acnes, and, as in adult acne, this results in follicular obstruction by sebum and keratin debris, and to inflammation.
#10 Infantile Acne – MD Searchlight
https://mdsearchlight.com/child-health/infantile-acne/
The exact cause of baby acne is still unknown. Current theories propose two possibilities. Firstly, genetic factors which make some babies more likely to develop acne. Secondly, there may be a heightened response in the babys oil-producing glands to standard levels of hormones present in the body, known as androgens. In baby girls, androgens come from adrenal glands, while in baby boys, they are produced by both adrenal and testicular glands. […] In rare cases, baby acne can signal the presence of a adrenal gland tumor. There are also isolated cases where a certain type of fungus, known as Malassezia, has been identified as a cause of baby acne.
#11 Why Does My Newborn Have Acne?
https://www.verywellhealth.com/newborn-baby-acne-15497
Newborn baby acne, also referred to as neonatal acne, is a condition that appears within the first six weeks of a baby’s life. The exact cause isn’t certain, but it’s thought to develop because of hormones or a reaction to yeast that lives on the skin. […] The direct cause of newborn baby acne is unknown. It may be caused by high levels of hormones passed to your baby through the placenta, which could affect the production of sebum in the skin. When there is too much of this oily substance, it can clog pores. […] Some research also suggests that an inflammatory reaction to skin colonization with Malassezia yeast can be the cause.
#12 Baby Acne: What Parents Need To Know – Riverchase Dermatology
https://www.riverchasedermatology.com/blog/baby-acne-what-parents-need-to-know/
Baby acne is usually harmless and typically clears up on its own. Still, itâs important to know how to avoid aggravating the babyâs skin and when to bring your baby to a dermatologist to make sure the condition doesnât require treatment. […] In most cases, newborn acne isnât technically acne at all. âVery early neonatal acne is more likely an inflammatory reaction to a yeast overgrowth,â said Robin Gehris, MD, a board certified adult and pediatric dermatologist at Riverchase Dermatology. […] It may start when hormones passed on from the mother just before she gives birth stimulate the glands that produce sebum, the oily substance that can clog pores. […] âYeast that normally live on the skin, called Malassezia, flourish when sebum production increases in newborns. The yeast, in turn, creates inflammation that results in neonatal acne,â said Dr. Gehris.
#13 Baby Acne: What causes it and how to manage it
https://www.cvs.com/learn/health/childrens-health/baby-acne
Baby acne and teenage acne arenât exactly the same thing. In older children and adults, acne crops up when pores become obstructed. Hormones play a role by stimulating the oil glands that can cause those obstructions to happen. […] âBut in general, babies donât really get acne,â says Yasmine Kirkorian, MD, chief of dermatology at Childrenâs National Hospital. âWhat we call âbaby acneâ doctors call neonatal cephalic pustulosis.â […] Neonatal cephalic pustulosis is a rash that occurs before 6 weeks of age. âWe think it reflects a normal response to the skinâs microbiome being established,â Dr. Kirkorian says. A yeast that lives on our skin (called Malassezia) establishes itself at that time, and some babies experience an inflammatory response that looks like clusters of pimples. […] In babies older than 3 months, however, more traditional forms of acne can develop. This is much less common â found in less than 2 percent of babies. Unlike neonatal cephalic pustulosis, infantile acne is believed to be related to clogged pores, hormones and increased oil production. It can also leave scars on the skin.
#14 Fungal Acne in Newborns: The Myth of Baby Acne | KINS Clinic
https://www.kins-clinic.com/blogs/fungal-acne-in-newborns-the-myth-of-baby-acne
Neonatal acne, a skin condition affecting approximately 20% of newborns, can be mistaken for typical adolescent acne vulgaris. […] These acneiform lesions seen in newborns can be commonly due to excessive maternal hormones, elevated sebum excretion rates and a condition known as fungal acne. […] Neonatal acne, also known colloquially as baby acne, is a term often used to describe acne-like skin lesions that occur due to increased production of placental and neonatal androgens. […] These hormones cause the sebaceous glands to enlarge and produce more sebum, leading to acne. […] Fungal acne in newborns is often associated with the colonisation of the skin by Malassezia species. […] Factors such as increased sebum production and hormonal changes in newborns can contribute to this overgrowth. […] While neonatal acne is a common term, it’s essential to understand that the acne-like lesions seen in newborns are often due to fungal acne.
#15 Baby Acne Explained: Causes, Symptoms, And Treatments
https://www.healthdigest.com/1168571/baby-acne-explained-causes-symptoms-and-treatments/
Baby acne has many alternate medical names, including neonatal acne and neonatal cephalic pustulosis. […] The exact cause of baby acne is still unclear, but there are a couple of theories. According to Cleveland Clinic, baby acne may be due to changes in your baby’s hormones caused by the placenta. The placenta may increase the production of sebum, which may clog skin pores and cause acne if produced in excess. […] With that said, the Department of Dermatology in the University of Utah School of Medicine disagrees that baby acne is caused by excess sebum. There is evidence that baby acne may be an inflammatory reaction to the yeast Malassezia, although this requires more research. […] Baby acne may possibly be linked to an infection with Malassezia, but other skin infections are not known to cause baby acne.

Newborn baby skin is naturally acne-prone. This acne-prone stage is a little-known, but normal, phase of skin development that affects over 20% of babies in the first 6 weeks of life. It occurs as your baby’s skin adjusts from the aquatic environment in mom’s belly to the air environment after delivery and to the rush of hormones your baby received from you shortly before birth. […] Baby acne is caused by one or a combination of 6 primary triggers on the skin surface: 1) hormonal imbalance 2) pH imbalance 3) vitamin/mineral imbalance 4) protective vs pathogenic bacterial imbalance 5) dehydration (also known as trans-epidermal water loss) 6) excess of a certain yeast called Malassezia. […] Acne and rosacea are caused by a body’s immune system reacting to microbes on the skin. But AAD found that a dose of probiotics applied to the skin prevents the body from creating that reaction.
#17 Baby Acne | LifeMD

Baby acne is a skin condition that causes small red or white blemishes to develop on a newborns face. […] Common causes of baby acne include skin immaturity and hormonal influences from the mother. […] The exact causes of baby acne arent fully understood yet, but there are a number of factors that may contribute to its development. […] During pregnancy, a mothers body undergoes significant hormonal shifts. Some of these hormones can cross the placenta and impact the unborn baby. […] Androgens are one group of hormones that fluctuate during pregnancy. […] They are known to stimulate sebaceous glands on the skin, which can cause excess oil to build up and clog the pores. Over time, this can lead to acne. […] When androgens enter the babys bloodstream, they can have a similar effect on the fetus developing oil glands, which may cause acne to appear.
#18 Baby Acne | LifeMD
https://lifemd.com/learn/baby-acne
A newborns skin is significantly different from that of older children and adults. […] Their skin is usually much thinner and more delicate, which can leave them vulnerable to conditions like acne. […] Newborns oil glands may be more active while their skin adjusts to their new environment. This can lead to excess sebum production and increase the risk of clogged pores. […] Due to these excessive immune responses, a babys skin can become more easily inflamed and vulnerable to acne. […] Its possible for hormones to pass into a mothers breast milk and cause acne to develop.

Baby acne in newborns is a skin ailment characterized by the appearance of small, red, or white bumps or pimples on the skin. […] Acne in infants has several possible reasons, but experts can only speculate: Pregnancy-related hormonal changes in the placenta might cause an overproduction of oil in the baby’s epidermis. […] Some researchers think the condition is caused by genes, hormones in the mother and baby, or things in the environment that irritate the skin. […] Teenagers and adults often get hormonal acne, and hormones from the mother are still in a baby’s body for the first few weeks of life. It is thought that leftover hormones can cause a type of acne in babies called hormonal acne. […] During pregnancy, hormones in the placenta can also make the oil glands on a baby’s skin work too hard. This could then lead to acne later on. […] Because a baby’s pores don’t fully form until after birth, they may be more likely to get acne from irritants in the outside world.
#20 Baby Eczema vs Acne: Crucial Differences Explained Clearly

Baby acne is characterized by small, non-itchy bumps that develop on the face, typically within the first few weeks after birth. This is due to the influence of maternal hormones in the womb and usually resolves on its own as hormone levels normalize. […] Baby acne is primarily caused by the exposure to maternal hormones during pregnancy. These hormones stimulate the baby’s sebaceous (oil) glands, which can lead to the formation of acne. […] An elevated pH can lead to an increase in sebum production, the blockage of pores, and the proliferation of bacteria that cause acne. […] Baby acne results from hormonal changes that cause the baby’s oil glands to produce excess sebum, which can then clog the pores and lead to the formation of pimples.

Baby acne is a common and temporary skin condition. Many newborns experience these harmless breakouts in their first few weeks of life. […] Understanding what causes baby acne and how to care for your little one’s skin can make all the difference. […] Baby acne is not caused by clogged pores or poor hygiene but is linked to maternal hormones and a baby’s developing skin. […] Experts believe natural factors like maternal hormones passed through the placenta may contribute to newborn acne. […] A primary cause of baby acne is the transfer of maternal hormones before birth. […] After birth, these lingering hormones can temporarily overstimulate the baby’s sebaceous (oil-producing) glands, leading to small red or white bumps on the skin. […] Genetics may also affect a baby’s likelihood of developing acne. If parents had acne as newborns, infants, or even later in life, their baby may be more prone to experiencing temporary breakouts. […] While baby acne differs from teenage or adult acne, genetic factors can influence how a newborn’s skin reacts to hormonal changes and environmental exposures.
#23 Everything You Need to Know About Baby Acne | ColumbiaDoctors

Baby acne is usually a harmless condition in babies. Up to 20% of newborns are affected by baby acne. The zits may take the form of pimples, pustules or bumps may appear on the face, chest sometimes other body parts. […] Exposure to mommys hormones when in the womb, is the generally suspected cause of baby acne. Occasionally, hormones passed through breast milk may also stand to be blamed. These hormones may mess with the babys sebum production machinery. Sebum is an oil-like substance that the human body produces for skin hair maintenance. And excess sebum may clog pores. This eventually leads to the formation of baby acne. […] Since your newborns skin is super sensitive, any external material on their skin such as food residue, saliva, etc, if left uncleaned, may react adversely cause baby acne.

Purulent pimples and blackheads in infants are the most common symptoms of infant acne. […] Although the causes of baby acne are not fully understood, there are currently several factors that predispose infants to develop this type of skin lesions. […] Hormonal disorders increased levels of androgens (including maternal hormones, which the infant receives in breast milk, and hormones produced by the child’s adrenal glands) stimulate the sebaceous glands to overproduce sebum. […] Bacterial colonization Propionibacterium acnes this is a bacterium that naturally occurs on the skin, but in infants it can overgrow, leading to inflammation of the hair follicles and the formation of blackheads and purulent pimples in an infant. […] Immaturity of infant skin – is one of the possible causes of baby acne. Babies’ skin physiologically produces more sebum, which contributes to the clogging of pores and the formation of so-called pimples. […] Inadequate care the use of cosmetics containing mineral oils, such as paraffin or petroleum jelly, may intensify skin lesions and be one of the causes of baby acne, exacerbating its symptoms.

During the final moments of pregnancy, a mothers hormones cross the placenta into her baby. These hormones stimulate oil glands on the babys skin (and do other incredible things like maturing the lungs), this stimulates the oil glands on the skin, eventually causing baby acne. […] The mothers hormones can be found in her breastmilk; therefore, they can cause breakouts. […] Abrasive soaps and washcloths may trigger baby acne. A newborns skin is quite sensitive and chemicals can cause many problems. […] Laundry detergent with strong chemicals, dyes, and perfumes may affect the skin and cause acne. […] Medications taken by the mother during pregnancy or while breastfeeding are passed to the baby as well. Each baby will handle these differently, but a common side effect would be a skin reaction. […] Mothers diet affects the baby when breastfeeding. Many doctors suggest cutting out dairy, sugar, and highly fatty foods, as all cause inflammation which can trigger acne.
#29 What causes baby acne?
https://www.babycenter.com/health/conditions/what-causes-baby-acne_72
