Diagnóisiú

Díagnóisiú galar coeliaca

Is é an botún is tábhachtaí a dhéanamh ná glútan a bhaint sula ndéantar tástáil ort. Déanann sé diagnóis shoiléir a fháil i bhfad níos deacra.

Cén fáth a gcaithfidh tú leanúint ar aghaidh ag ithe glútan

Déantar diagnóisiú galar coeliac trí fhreagairt imdhíonachta a bhrath do ghlútan agus an damáiste intestinal a dhéanann sé. Bain glútan agus déantar an dá rud a laghdú: laghdaíonn frithghníomhartha go gnáth thar seachtain go míosa, agus tosaíonn na villi ag dul i ngleic. Déan tástáil ag an bpointe sin agus is é an toradh nach féidir a léirmhíniú.

Is é an leigheas ná dúshlán glútan — glútan a chur ar ais go deonach ar feadh seachtainí roimh thástáil — rud atá míchompordach go leor go gcuireann go leor daoine é ar ceal agus críochnaíonn siad le aiste bia srianta ar feadh an tsaoil agus gan diagnóis. Tá sé sin níos tábhachtaí ná mar a chloistear: gan diagnóis, d'fhéadfadh nach bhfaighidh tú monatóireacht ar dhlúth na cnámh, tacaíocht aiste bia ar leith do ghalar coeliac, nó i roinnt tíortha Eorpacha na cearta leighis agus suimeanna a thagann leis.

An seicheamh tástála

Cosán diagnóise caighdeánach do dhaoine fásta
CéimTástáilCad a insíonn sé duit
1Transglutaminase tísí IgA (tTG-IgA) + IgA iomlánAn tástáil scagtha. Méadaítear IgA iomlán toisc go gcuireann easnamh freagairí bréagacha diúltacha ar fáil.
2Frithghníomhartha endomysial (EMA) má tá tTG neamhchinnteSerology dearbhaithe an-íogair.
3Biopsy duodenum, samplaí ilchasta lena n-áirítear an bulbAtrophy villous a ghrádáil de réir na rangúcháin Marsh. Is é an galar patchy an fáth go bhfuil samplaí ilchasta tábhachtach.
4HLA-DQ2/DQ8 i gcásanna amhrasachaEisiíonn toradh diúltach go héifeachtach galar coeliac.

Aontaíonn na treoirlínte Eorpacha 2025 [2] agus treoirlínte Coláiste Mheiriceá na nGastrónómach ar an gcruth ginearálta seo, le difríochtaí ag na teorainneacha — go háirithe maidir le cathain is féidir biopsy a eisiamh.

Cosán diagnóise

Galar coeliac féideartha

Catagóir mearbhall: frithghníomhartha dearfacha, biopsy gnáth. Scrúdaíodh athruithe cliniciúla sa ghrúpa seo i léirmheas córais agus meta-anailís i Gut, rud a bhfuil tábhacht aige toisc nach bhfuil freagra soiléir ar an gceist bainistíochta — cóireáil anois nó monatóireacht — ann. Déanann go leor, ach ní gach duine, dul ar aghaidh go atrophy villous thar am.

Cé ba chóir tástáil a dhéanamh orthu

  • Diaibéiteas ghrónna, bloating, nó caillteanas meáchain neamhshonraithe.
  • Anaemia easnamhach iarainn gan cúis shoiléir — cur i láthair an-choitianta, agus áit a n-ardóidh treoirlínte gastroenterology go sonrach tástáil ghalair coeliac [7].
  • Gaol díreach le galar coeliac, áit a bhfuil an scaipeadh thart ar deich n-uaire an ráta cúlra.
  • Diaibéiteas cineál 1, galar thyroid uathoibríoch, agus roinnt galar uathoibríoch eile a chruinníonn leis.
  • Ardú neamhshonraithe ar transaminases, ulcers béil athfhillteacha, nó osteoporóis luath.
  • Dermatitis herpetiformis, atá i ndáiríre galar coeliac ar an gcraiceann agus atá diagnóiseach ina féin.

Tabhair faoi deara cad atá ní ar an liosta sin: bloating amháin, i absence aon rud eile, is minic a bhíonn sé i gcoitinne galar boilg irritable — agus is é an treoirlínte ACG ar bhainistíocht IBS [4] an doiciméad níos ábhartha do chuid de na cur i láthair sin. Tá galar coeliac agus IBS go leor comhoibrithe go gcaithfidh an difríocht tástáil a dhéanamh seachas conas a thuar.

Ceisteanna coitianta

An féidir liom a bheith diagnóisithe gan bithóipse?
I leanaí, ceadaíonn roinnt conairí é ag teidil antashubstaintí an-ard le tástáil dhaingniúcháin. In aosaigh, fanann bithóipse mar chaighdeán sa chleachtas Eorpach den chuid is mó.
Cé mhéad glútan a chaithfidh mé a ithe sula ndéantar tástáil?
Athraíonn treoir ach ciallaíonn sé go ginearálta béilí gnáthghlútanacha go laethúil ar feadh roinnt seachtainí. Ba chóir do do ghastrointeolaí an fad ama a shonrú.
An bhfuil tástálacha antashubstaintí baile iontaofa?
Is féidir leo fadhb fhéideartha a chur in iúl ach ní féidir leo diagnóisiú a dhéanamh. Teastaíonn daingniú saotharlainne agus bithóipse ó thoradh dearfach; ní chuireann toradh diúltach an galar as an áireamh, go háirithe má tá glútan laghdaithe agat cheana féin.
Bhí mo chuid tástálacha diúltach ach déanann glútan tinn mé. Cad anois?
Is staid aitheanta í sin — féach íogaireacht glútain neamh-chéiliach, áit a bhfuil an fhianaise FODMAP thar a bheith ábhartha.
