Preporuka za evaluaciju i tretman

Ova djevojčica vjerovatno ima preuranjenu pubarhu (premature pubarche) koja ne zahtijeva laboratorijsko testiranje niti tretman u ovom trenutku, već samo kliničko praćenje.

Razlog za ovaj pristup

Djevojčica ima samo fine dlake u pubičnoj regiji (P1 stadijum), masnu kosu i sitne bubuljice na čelu – sve to su blagi znaci adrenarhe bez znakova virilizacije ili pravog pubertetskog razvoja. Najvažnije je da nema razvoj dojki, što isključuje centralni prerani pubertet 1.

Ključni faktori u ovoj procjeni:

Ubrzana kostana dob od 15 mjeseci nije alarmantna. Kod preuranjene pubarhe, blago ubrzana kostana dob (obično 1-2 godine) je uobičajena i dobro korelira sa visinom djeteta. Ovo ne utiče negativno na konačnu visinu 2. U ovom slučaju, 15 mjeseci je na granici normalnog za preuranjenu pubarhu.

Porodična anamneza ekstremne visine je zaštitni faktor. Sa ženama do 185cm i muškarcima do 2m, genetski potencijal za visinu je izuzetan, što dodatno smanjuje zabrinutost oko konačne visine.

Kada NE testirati

Prema najnovijim dokazima, laboratorijsko testiranje i kostana dob nisu potrebni kod preuranjene pubarhe osim ako postoje "crvene zastavice" 1. Ova djevojčica nema:

  • Brzi rast i progresiju simptoma
  • Uvećanje klitorisa ili drugih genitalija
  • Razvoj dojki (što bi ukazivalo na centralni prerani pubertet)
  • Znake virilizacije (duboki glas, značajna akne, hirzutizam)

Kada razmotriti testiranje

Prema smjernicama Endocrine Society, testiranje za neklasičnu kongenitalnu adrenalnu hiperplaziju (NCCAH) je indikovano samo kod djece sa "neprikladno ranim početkom i brzom progresijom pubarhe ili kostane dobi" 3.

Specifični kriterijumi za testiranje:

  • Ako kostana dob napreduje brže od 2 godine u odnosu na hronološku dob
  • Ako se pojave znaci virilizacije (ne samo fine dlake)
  • Ako dođe do brzog rasta sa značajnim ubrzanjem kostane dobi koje bi ugrozilo konačnu visinu
  • Ako se razviju dojke (što bi ukazivalo na centralni prerani pubertet)

Preporučeni plan praćenja

Kliničko praćenje svakih 3-6 mjeseci sa:

  • Procjenom Tanner stadijuma (posebno dojki - bilo koji razvoj zahtijeva hitnu evaluaciju)
  • Mjerenjem visine i brzine rasta
  • Procjenom progresije dlaka, akni i drugih znakova
  • Razgovorom sa porodicom o znacima za zabrinutost

Ponovite kostanu dob za 6-12 mjeseci samo ako:

  • Brzina rasta značajno ubrzava
  • Simptomi brzo napreduju
  • Pojave se novi znaci virilizacije

Važna upozorenja

Isključite egzogenu izloženost estrogenima ili androgenima. Pitajte da li neko u kući koristi hormonske gelove, kreme ili flastere 4. Ovo je često zanemareni uzrok.

Porodična hirzutizam i visina sugerišu genetsku predispoziciju koja može objasniti ranije pojave dlaka, ali to ne znači da je patološko 5.

Dugoročno praćenje je važno jer neke studije pokazuju da djevojčice sa preuranjenom pubarhe mogu imati povećan rizik za insulinsku rezistenciju i policistične jajnike kasnije u životu 6, 2. Međutim, ovo ne zahtijeva tretman sada, već samo svijest o potrebi praćenja kroz adolescenciju.

Kada započeti tretman

Tretman glukokortikoidima je indiciran SAMO ako 3:

  • Potvrđena je NCCAH laboratorijski (17-OHP >1000 ng/dL nakon ACTH stimulacije)
  • Kostana dob je toliko ubrzana da će negativno uticati na konačnu visinu
  • Postoje znaci ozbiljne virilizacije

U ovom trenutku, ova djevojčica ne ispunjava nijedan od ovih kriterijuma.
