Trattamenti barra d-dieta mingħajr glutina

Bosta approċċi waslu għal trials randomizzati. L-ebda ma sostitwixxa d-dieta, u l-qasam għandu storja twila ta' riżultati promettenti li ma żammewx.

Għaliex mediċina hija diffiċli

Il-keliakija għandha proprjetà mhux tas-soltu fost il-kundizzjonijiet awtoimmuni: il-kawża hija magħrufa u tista' tiġi eliminata. Dan jissettja livell għoli ħafna — kwalunkwe mediċina trid tkun aktar sigura u aktar konvenjenti milli sempliċement ma tiekolx glutina, f'popolazzjoni li mhix morda akutament ladarba tkun trattata. Dan ifisser ukoll li l-għan realistiku m'huwa mhux "iekol ħobż mill-ġdid" iżda "ikun protett meta r-ristorant jagħmel żball".

Inibizzjoni ta' transglutaminase 2

Transglutaminase tat-tessuti timmodifika l-peptidi tal-glutina b'mod li jagħmilhom ħafna aktar immunoġeniċi — hija l-enzima ċentrali fil-mekkaniżmu tal-marda u l-mira tal-antikor użat biex tiġi ddiagnostikata. L-iffriżar tagħha huwa għalhekk elegantikament mekkaniku. Trial randomizzat ta' inibitur TG2 rapporta tnaqqis tal-injury mużkolari kkawżata mill-glutina waqt il-challenge [5], li huwa l-iktar riżultat wieħed promettenti li l-qasam produċa.

Inibizzjoni TG2

Degradazzjoni enzimatika

Il-glutenases jimmiraw li jbreakjaw il-glutina fil-stomaku qabel ma tasal għall-intestinu żgħir. Il-problema inġinerija hija s-severità: biex jipproteġu kontra ikla normali ta' frument, enzima trid tniġġes grams ta' proteina f'ambjent aċiduż ostili fi żmien qasir. Bosta kandidati wrew attivitá kontra ammonti żgħar mingħajr ma wrew protezzjoni kontra l-espożizzjoni realista. Ix-xogħol fuq preparazzjonijiet probiotici b'attività ta' degradazzjoni tal-glutina in vivo jillustra l-approċċ.

Probiotici

Reviżjoni sistematika u meta-analiżi ta' trials kontrollati randomizzati ta' probiotici għall-keliakija eżistu u ma jappoġġjawx l-użu rutin. Id-differenzi fil-mikrobioma fil-keliakija huma reali u riproduċibbli, iżda l-modifika tagħhom ma traduxxewx f'benefiċċju kliniku.

Direzzjonijiet oħra

  • Induzzjoni ta' tolleranza immuni. Approċċi bbażati fuq peptidi li jimmiraw li jerġgħu jistrutturaw ir-risposta immuni, simili fil-kunċett għal immunoterapija għall-allergeni.
  • Modulazzjoni tal-ġunġla stretta. In-nuqqas ta' permeabilità intestinali sabiex in-nies jikkrossaw inqas peptidi tal-glutina. Il-trials kienu miksura.
  • Blokki ta' cytokine. Immirati lejn mard refrattari aktar milli lejn il-keliakija ordinarja [7].
  • Vaċċinazzjoni. Diskussa fit-tul, iddilata ripetutament, u mhux viċin.

X'għandek tistenna

Il-pass li jmiss plawżibbli huwa adjunct li jnaqqas il-konsegwenzi tal-espożizzjoni aċċidentali għal nies li diġà huma stretti. Dan ikun verament ta' valur — l-espożizzjoni inavertita hija komuni, kif juri r-riċerka dwar il-kontaminazzjoni — mingħajr ma jkun il-libertà li l-kopertura t-tendenza tipprometti.

Mistoqsijiet komuni

Se jkun hemm pillola li tippermetti li niekol ħobż?
Le skont l-evidenza attwali. Il-trials jimmiraw li jipproteġu kontra l-kontaminazzjoni, mhux ir-ripresa ta' dieta normali.
Għandi nieħu enzima li digesti l-glutina?
Ma ġewx muri li jipproteġu kontra l-espożizzjoni tal-glutina ta' daqs tal-ikla, u fid-dipendenza fuq waħda hija riskjuża.
Huma probiotici ta' valur li jippruvaw?
Meta-analiżi ta' trials randomizzati ma tappoġġjaxhom għall-keliakija b'mod speċifiku.
Kif nista' nissieħeb f'trial?
Is-soċjetajiet nazzjonali tal-keliakija u r-reġistri ta' trials klinċi jlistaw studji li qed jirkupraw; il-gastroenterolog tiegħek jista' jippjana dwar l-eligibbiltà.
