In the last few years a new clinical entity has emerged which includes patients who consider themselves to be suffering from problems caused by wheat and/or gluten ingestion, even though they do not have celiac disease (CD) or wheat allergy. This clinical condition has been named non-celiac gluten sensitivity (NCGS), although in a recent article, the researchers suggested the term "non-celiac wheat sensitivity" (NCWS), because it is not known to date what component of wheat actually causes the symptoms. The clinical picture of NCWS is characterized by combined gastrointestinal (bloating, abdominal pain, diarrhea and/or constipation, nausea, epigastric pain, gastroesophageal reflux, aphthous stomatitis) and extra-intestinal or systemic manifestations (headache, depression, anxiety, 'foggy mind,' tiredness, dermatitis or skin rash, fibromyalgia-like joint/muscle pain, leg or arm numbness, and anemia). Lactose intolerance and cow's milk protein allergy (CMPA) are two medical conditions with a very high prevalence in the general population, and there is a large overlap between NCWS symptoms and lactose intolerance and CMPA symptoms. Therefore, the aims of the present study are to investigate 1) the prevalence of positive lactose breath test and DBPC cow's milk protein challenge in NCWS patients with self-reported gastrointestinal symptoms related to milk and/or milk derivates ingestion, 2) the clinical, serological, and histological characteristics of NCWS patients with lactose intolerance and CMPA in comparison to NCWS patients without lactose intolerance and CMPA.

Eligibility |
Inclusion Criteria: All the NCWS patients will meet the recently proposed criteria: - negative serum anti-tissue transglutaminase and antiendomysium (EmA) IgA and IgG antibodies - absence of intestinal villous atrophy - IgE-mediated immunoallergy tests negative to wheat and cow's milk protein (skin prick tests and/or serum specific IgE detection). Adjunctive criteria adopted in our patients will be: - resolution of the gastrointestinal and extra-intestinal symptoms on a standard elimination diet, without wheat, cow's milk, egg, tomato, chocolate, or other food(s) causing self-reported symptoms - symptom reappearance on double-blind placebo-controlled (DBPC) wheat challenge, performed as described previously. Exclusion Criteria: Exclusion criteria will be: - age <18 years - positive EmA in the culture medium of the duodenal biopsies, even if the villi to crypts ratio in the duodenal mucosa was normal - self-exclusion of wheat from the diet and refusal to reintroduce it before entering the study - other organic cutaneous and/or gastrointestinal diseases - concomitant treatment with steroids and/or antihistamines. Lactose intolerance and CMPA will be diagnosed, in patients with self-reported gastrointestinal and extra-intestinal symptoms related to milk and/or milk derivates ingestion, using lactose breath test and DBPC cow's milk protein challenge, respectively. |
