Zdravljenja poleg brezglutenske diete

Več pristopov je doseglo randomizirane študije. Noben ni nadomestil diete, področje pa ima dolgo zgodovino obetavnih rezultatov, ki niso bili potrjeni.

Zakaj je zdravilo težko

Celiakija ima nenavadno lastnost med avtoimunskimi stanji: sprožilec je znan in odstranljiv. To postavlja zelo visoko merilo — vsako zdravilo mora biti varnejše in bolj priročno kot preprosto ne jesti glutena, v populaciji, ki ni akutno bolna, ko je zdravljena. To pomeni, da realističen cilj ni "spet jesti kruh", temveč "biti zaščiten, ko restavracija naredi napako".

Inhibicija transglutaminaze 2

Tissue transglutaminaza modificira gluten peptide na način, ki jih naredi veliko bolj imunogene — to je encim v središču mehanizma bolezni in cilj protitelesa, ki se uporablja za diagnozo. Njegovo blokiranje je torej mehanistično elegantno. Randomizirana študija inhibitorja TG2 je poročala o zmanjšanju poškodb sluznice, ki jih povzroča gluten, med izzivom [5], kar je najbolj obetaven posamezen rezultat, ki ga je to področje doseglo.

Inhibicija TG2

Encimska razgradnja

Glutenaze si prizadevajo razgraditi gluten v želodcu, preden doseže tanko črevo. Inženirski problem je resnost: za zaščito pred običajnim obrokom pšenice mora encim razgraditi grame beljakovin v sovražnem kislem okolju v kratkem času. Več kandidatov je pokazalo aktivnost proti majhnim količinam, ne da bi pokazali zaščito pred realističnim izpostavljanjem. Delo na probiotikih z in vivo aktivnostjo razgradnje glutena ponazarja pristop.

Probiotiki

Obstaja sistematičen pregled in meta-analiza randomiziranih kontroliranih študij probiotikov za celiakijo, ki ne podpira rutinske uporabe. Razlike v mikrobiomu pri celiakiji so resnične in ponovljive, vendar njihovo spreminjanje ni privedlo do klinične koristi.

Druge smeri

  • Indukcija imunskega tolerance. Pristopi, ki temeljijo na peptidih, ki si prizadevajo ponovno usposobiti imunskega odziva, konceptualno podobni imunoterapiji z alergeni.
  • Modulacija tesnih stikov. Zmanjšanje črevesne prepustnosti, da manj glutenskih peptidov prečka. Poskusi so bili mešani.
  • Blokada citokinov. Usmerjena na refraktorno bolezen, ne na običajno celiakijo [7].
  • Cepljenje. Dolgo razpravljano, večkrat odloženo in ne blizu.

Kaj pričakovati

Verjeten naslednji korak je dodatek, ki zmanjšuje posledice nenamerne izpostavljenosti za ljudi, ki so že strogi. To bi bilo resnično dragoceno — nenamerna izpostavljenost je pogosta, kot kaže raziskava o kontaminaciji — brez obljube svobode, ki jo pokritost običajno obljublja.

Pogosta vprašanja

Ali bo obstajala tableta, ki mi omogoča jesti kruh?
Na podlagi trenutnih dokazov ne. Poskusi ciljajo na zaščito pred kontaminacijo, ne na ponovno uvedbo običajne diete.
Ali naj jemljem encim za razgradnjo glutena?
Niso bili dokazani, da bi zaščitili pred izpostavljenostjo glutenu v velikosti obroka, in zanašanje na enega je tvegano.
Ali so probiotiki vredni poskusa?
Meta-analiza randomiziranih študij jih ne podpira za celiakijo posebej.
Kako bi se pridružil študiji?
Nacionalna celiakalna društva in registri kliničnih študij navajajo študije, ki iščejo udeležence; vaš gastroenterolog vam lahko svetuje glede upravičenosti.
