Beskrivelse
Inclusion criteria of celiac disease patients:
- Diagnosis of CD was based on the detection of IgA antiendomysial and IgA antitissue transglutaminase antibodies in serum
- Diagnosis must be confirmed by a small intestinal biopsy obtained at the time of gastrointestinal endoscopy.
- All patients must show Marsh 3 grade villous atrophy at the time of the diagnosis.
Inclusion criteria of IBS patients.
- Subjects suffering from irritable bowel syndrome according to the Rome III criteria.
- Availability of at least one GI imaging study during the last five years (colonoscopy, sigmoidoscopy, abdominal ultrasound, barium enema)
Exclusion criteria for both the above groups:
- None were taking anti-inflammatory drugs (including mast cell stabilisers, histamine antagonists, anticholinergics, anti-diarrhoea medication, probiotics, immunosuppressants and steroids)
- Presence of organic syndrome, including food allergy, atopy and severe clinical depression or anxiety.
- Abnormal laboratory data or thyroid function
- Major abdominal surgery Healthy subjects will be recruited in the administrative staff of the Institute after thorough exclusion of GI symptoms.

Intestinal permeability
Tidsramme: within one month after the enrollment
|
The detection and measurement of two sugar probes, lactulose (La) and mannitol (Ma), in the urine will be performed by chromatographic analysis.
For each sample the percentage of ingested La and Ma in urine will be evaluated and their ratio (La-Ma) will be calculated.
