Tretmani izvan bezglutenske dijete

Nekoliko pristupa je došlo do randomiziranih ispitivanja. Nijedan nije zamijenio dijetu, a polje ima dugu historiju obećavajućih rezultata koji nisu održani.

Zašto je lijek teško razviti

Celijakija ima neobičnu osobinu među autoimunim stanjima: okidač je poznat i uklonjiv. To postavlja vrlo visoke standarde — svaki lijek mora biti sigurniji i praktičniji od jednostavnog nejedanja glutena, u populaciji koja nije akutno bolesna nakon liječenja. Također, to znači da realističan cilj nije "ponovo jesti hljeb" već "biti zaštićen kada restoran pogriješi".

Inhibicija transglutaminaze 2

Tjelesna transglutaminaza modificira peptide glutena na način koji ih čini daleko imunogenijim — to je enzim u središtu mehanizma bolesti i cilj antitijela koje se koristi za dijagnosticiranje. Njegovo blokiranje je stoga mehanistički elegantno. Randomizirano ispitivanje TG2 inhibitora izvijestilo je o ublažavanju oštećenja sluznice izazvanog glutenom tokom izazova [5], što je najhrabriji pojedinačni rezultat koji je polje proizvelo.

Inhibicija TG2

Enzimska razgradnja

Glutenaze imaju za cilj razgradnju glutena u želucu prije nego što dođe do tankog crijeva. Inženjerski problem je ozbiljnost: da bi se zaštitili od normalnog obroka pšenice, enzim mora razgraditi grame proteina u neprijateljskom kiselom okruženju unutar kratkog vremenskog okvira. Nekoliko kandidata je pokazalo aktivnost protiv malih količina bez demonstriranja zaštite od realističnog izlaganja. Rad na probiotskim pripravcima s in vivo aktivnošću razgradnje glutena ilustrira pristup.

Probiotici

Sistematski pregled i meta-analiza randomiziranih kontroliranih ispitivanja probiotika za celijakiju postoje i ne podržavaju rutinsku upotrebu. Razlike u mikrobiomu kod celijakije su stvarne i reproducibilne, ali njihovo modificiranje nije dovelo do klinične koristi.

Ostale smjernice

  • Indukcija imunološke tolerancije. Pristupi zasnovani na peptidima koji imaju za cilj ponovno obučiti imunološki odgovor, konceptualno slični imunoterapiji alergena.
  • Modulacija čvrstih spojeva. Smanjenje intestinalne propusnosti kako bi se manje peptida glutena prešlo. Ispitivanja su bila mješovita.
  • Blokada citokina. Usmjerena na refraktornu bolest, a ne na običnu celijakiju [7].
  • Vakcinacija. Dugo raspravljana, više puta odložena i nije blizu.

Šta očekivati

Mogući sljedeći korak je dodatak koji smanjuje posljedice slučajnog izlaganja za ljude koji su već strogi. To bi bilo zaista vrijedno — nenamjerno izlaganje je uobičajeno, kao što pokazuje istraživanje o kontaminaciji — bez da predstavlja slobodu koju pokrivenost obično obećava.

Česta pitanja

Hoće li biti tableta koja mi omogućava da jedem hljeb?
Ne prema trenutnim dokazima. Ispitivanja se fokusiraju na zaštitu od kontaminacije, a ne na nastavak normalne dijete.
Trebam li uzimati enzim za probavljanje glutena?
Nisu pokazali zaštitu od izlaganja glutenu u veličini obroka, a oslanjanje na jedan je rizično.
Da li vrijedi probati probiotike?
Meta-analiza randomiziranih ispitivanja ne podržava ih specifično za celijakiju.
Kako bih se pridružio ispitivanju?
Nacionalna društva za celijakiju i registri kliničkih ispitivanja navode studije koje regrutuju; vaš gastroenterolog može savjetovati o podobnosti.
