Fá diagnosu við cøliaki

Einasta mest avgerandi feilin er at fjarlægja gluten áðrenn tú verður kannaður. Tað ger eina avgerandi diagnosu nógv torførari at fáa.

Hví tú mást halda fram at eta gluten

Cøliaki verður diagnoserað við at avdúka immunresponsin móti gluten og tarmaskaðanum, tað fer at orsaka. Fjalda gluten og bæði blekna: antikroppar falla móti normalum yvir vikur til mánaðir, og villi byrja at batna. Kanna á tí punktinum og úrslitið er ógreitt.

Løttingin er ein gluten avbjóðing — at endurgeva gluten í fleiri vikur áðrenn kanning — sum er so óbehagilig at nógv fólk avmarka tað og enda við einum livandi avmarkaðum kost og uttan diagnosu. Tað hevur meira at siga enn tað hoyrist: uttan eina diagnosu kanst tú ikki fáa eftirfylgjandi beinadensitetskanning, cøliaki-sérfakligan kostveitingarstøtt, ella í fleiri evropeiskum londum, lyknir og stuðul rættindi, sum koma við tí.

Kanningarøð

Standard diagnosuleið í vaksnum
SkrittKanningHvat tað sigur tær
1Vevja transglutaminasa IgA (tTG-IgA) + total IgAKanningarúslitið. Total IgA verður mált, tí skortur gevur falskar neitandi úrslit.

4HLA-DQ2/DQ8 í ógreiðum førumEin neitandi úrslit útskrivar effektivt cøliaki.

2025 evropeisku leiðbeiningarnar [2] og leiðbeiningarnar frá American College of Gastroenterology eru samdar um hesa almennu bygging, við munum í kantunum — serliga um hvat tíðspunkt ein biopsi kann verða útlátin.

Diagnosuleið

Møgulig cøliaki

Ein forvirrandi kategori: positiv serologi, normal biopsi. Ein systematisk endurskoðan og meta-analyse í Gut granskaði kliniskar úrslit í hesum bólki, sum hevur týdning, tí at spurningurin um stýring — at behandla nú ella at fylgja við — hevur onga greitt svar. Mong, men ikki øll, fara til villøs atrofia yvir tíð.

Hvat skal verða kannað

  • Kronisk diarrea, uppblásing, ella ógreiddur vættataps.
  • Járnskortur anemi uttan ein greitt orsøkt — ein sera vanlig framstilling, og ein har gastroenterologiskar leiðbeiningar serliga nevna cøliaki kanningar [7].
  • Ein fyrsti-grads ættingi við cøliaki, har tíðnin er umleið tíggju ferðir bakgrundartíðnina.
  • Type 1 diabetes, autoimmune skjoldbrúskusjúkur, og fleiri aðrar autoimmune sjúkur, sum klumpa seg við henni.
  • Ógreiddur hægri transaminasar, endurteknar munnsár, ella tíðligur beinvevssjúka.
  • Dermatitis herpetiformis, sum í raun er cøliaki í húðini og er diagnosandi í sær sjálvum.

Legg til merkis hvat er ikki á tí listanum: uppblásing einsamøll, í fráveru av øðrum, er langt oftari irritabel tarmasyndrom — og ACG leiðbeiningin um IBS stýring [4] er tann meira viðkomandi dokumentið fyri flestu av teimum framstillingum. Cøliaki og IBS overlappa nóg mikið at munurin genuint hevur brúk fyri kanning heldur enn at gessa.

Vanlig spurningar

Kann eg fáa diagnosu uttan bíopsi?
Hjá børnum loyva summar leiðir hetta við sera høgum antistoffatiterum saman við váttandi testing. Hjá vaksnum er bíopsi framvegis standard í mesta parti av evropeiskari praksis.
Hvussu nógv gluten mugu eg eta, áðrenn eg verði testaður?
Rátgeving broytist, men merkir vanliga vanlig máltíð við gluteni hvønn dag í nøkur vikur. Tín gastroenterologur eigur at áseta longdina.
Eru heimaantistoffatestir álítandi?
Teir kunnu vísa á møguligan trupulleika, men kunnu ikki diagnosera. Eitt positivt úrslit krevur váttan á laboratoriu og bíopsi; eitt negativt útiletur ikki sjúkuna, serliga um tú longu hevur minkað um gluten.
Mínir testir vóru negativir, men gluten fær meg at kenna meg illa. Hvat nú?
Hetta er ein viðurkend støða — sí glutenviðkvæmni uttan cøliaki, har FODMAP-prógvið er serliga viðkomandi.
