Study type | Observational |
Non-celiac gluten sensitivity (NCGS) or 'wheat sensitivity' (NCWS) is included in the
spectrum of gluten-related disorders. No data are available on the prevalence of low bone
mass density (BMD) in NCWS. Our study aims to evaluate the prevalence of low BMD in NCWS
patients and search for correlations with other clinical characteristics.
This prospective observation study will include 90 NCWS patients with irritable bowel
syndrome (IBS)-like symptoms, 90 IBS and 90 celiac controls. Patients will be recruited at
the Internal Medicine and at the Gastroenterology Units of the University of Palermo.
Elimination diet and double-blind placebo controlled (DBPC) wheat challenge proved the NCWS
diagnosis. All subjects underwent BMD assessment by Dual Energy X-Ray Absorptiometry (DXA),
duodenal histology, Human Leukocyte Antigen (HLA) DQ typing, body mass index (BMI) evaluation
and assessment for daily calcium intake.

Eligibility |
Inclusion Criteria: To diagnose NCWS the recently proposed criteria will be adopted. All the patients will meet the following criteria: - negative serum anti-transglutaminase (anti-tTG) and anti-endomysium (EmA) immunoglobulin (Ig)A and IgG antibodies; - absence of intestinal villous atrophy; - negative IgE-mediated immune-allergy tests to wheat (skin prick tests and/or serum specific IgE detection); - resolution of the IBS symptoms on standard elimination diet, excluding wheat, cow's milk, egg, tomato, chocolate, and other self-reported food(s) causing symptoms; - symptom reappearance on double-blind placebo-controlled (DBPC) wheat challenge. As the investigators previously described in other studies, DBPC cow's milk protein challenge and other "open" food challenges will be performed too. Additional inclusion criteria will be: - age >18 years; follow-up duration longer than six months after the initial diagnosis; - at least two outpatient visits during the follow-up period. Exclusion Criteria: - positive EmA in the culture medium of the duodenal biopsies, also in the case of normal villi/crypts ratio in the duodenal mucosa; - self-exclusion of wheat from the diet and refusal to reintroduce it, before entering the study; - other "organic" gastrointestinal disorders; - nervous system disease and/or major psychiatric disorder; - physical impairment limiting physical activity; - menopause; - steroid and sex steroid therapy, hormone replacement therapy or ovariectomy. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in bone mineral density (BMD) | BMD will be assessed by dual x-ray absorptiometry (DXA), using a QDR Discovery Hologic DXA scanner in the femoral neck and in the lumbar spine. For each scan, BMD and T-scores will be recorded. A T-score between +1 and -1 is considered normal, between -1 and -2.5 indicates osteopenia, -2.5 or lower indicates osteoporosis. The investigators also will calculate the 10-year fracture risks according to the standardized WHO FRAX equation, computed with BMD (T-score) at the femoral neck. | At baseline and at 24 months | |
Secondary | Conventional lateral spine x-ray as an assessment of suspected osteoporotic vertebral fractures, using Genant's method | A random sample of the patients and controls will undergo conventional lateral spine x-ray for better assessment of suspected osteoporotic vertebral fractures, according to Genant's method (grade 0, no reduction; grade 1, minimal fracture, 20-25% vertebral height decrease; grade 2, moderate fracture, 25-40% vertebral height decrease; and grade 3, severe fracture, greater than 40% vertebral height decrease). | At baseline | |
Secondary | Change in serum bone alkaline phosphatase | Serum bone alkaline phosphatase values will be detected (refences values of adults males < or =20 mcg/L; of adults premenopausal females < or =14 mcg/L; of adults postmenopausal females < or =22 mcg/L). | At baseline and at 24 months | |
Secondary | Change in serum 25-hydroxyvitamin D | Serum 25-hydroxyvitamin D values will be detected (refences values 30.0-74.0 ng/mL). | At baseline and at 24 months | |
Secondary | Change in serum phosphorus levels | Serum phosphorus levels values will be detected (refences values of subjects > or =18 years: 2.5-4.5 mg/dL). | At baseline and at 24 months | |
Secondary | Change in serum calcium levels | Serum calcium levels values will be detected (refences values of males age 18-21 years: 9.3-10.3 mg/dL, age 22 years and older: 8.9-10.1 mg/dL; of females age 18 years and older: 8.9-10.1 mg/dL) | At baseline and at 24 months | |
Secondary | Change in urinary phosphorus levels | Urinary phosphorus levels values will be detected (refences values 0.4-1.3 g per 24-hour urine sample). | At baseline and at 24 months | |
Secondary | Change in urinary calcium levels | Urinary calcium levels values will be detected (refences values 100-300 mg per 24-hour urine sample). | At baseline and at 24 months | |
Secondary | Change in dietary intake and lifestyle | All the participants will fill in a health and lifestyle questionnaire, considering menarche and age at menopause (if applicable), medical and drug abuse history, lifestyle habits (including elimination diet, smoking status, alcohol consumption, Italian espresso coffee drinking and physical activity); history of bone fractures will also be recorded. In order to assess daily caloric intake and calcium intake, the subjects will receive a dietary form containing a printed list of the most common foods. | At baseline and at 24 months |
