OBJECTIVES Positivity of both immunoglobulin A anti-tissue transglutaminase (TTG) and anti-endomysium antibodies (EMA) has a positive predictive value of nearly 100% for celiac disease (CD). The objective of the present study was to evaluate whether patients of any age, with high pretest probability of CD and high titre of anti-TTG and EMA positivity, have(More)
Peripheral T-cell lymphomas (TCLs) are uncommon neoplasms, accounting for about 12% of all lymphoid tumors worldwide. TCLs in which gammadelta T-cell receptors are expressed (gammadelta TCLs) are extremely aggressive and rare (<1% of lymphoid neoplasms). gammadelta TCLs originate from gammadelta T cells, a small subset of peripheral T cells with direct(More)
AIM To evaluate the reliability of the bright liver (BL) echo pattern on ultrasound to detect histological steatosis in chronic cryptogenic hypertransaminasaemia (CCH) and hepatitis C virus (HCV)-related forms of hypertransaminasaemia. MATERIALS AND METHODS One hundred and fifty patients, 54 with CCH and 96 with HCV hypertransaminasaemia (76 genotype 1/2(More)
BACKGROUND Chronic diarrhea is the most common gastrointestinal symptom of intolerance of cow's milk among children. On the basis of a prior open study, we hypothesized that intolerance of cow's milk can also cause severe perianal lesions with pain on defecation and consequent constipation in young children. METHODS We performed a double-blind, crossover(More)
OBJECTIVES Non-celiac wheat sensitivity (WS) is considered a new clinical entity. An increasing percentage of the general population avoids gluten ingestion. However, the real existence of this condition is debated and specific markers are lacking. Our aim was thus to demonstrate the existence of WS and define its clinical, serologic, and histological(More)
BACKGROUND Celiac disease (CD) diagnosis is becoming more difficult as patients with no intestinal histology lesions may also be suffering from CD. AIM To evaluate the diagnostic accuracy of antiendomysium (EmA) assay in the culture medium of intestinal biopsies for CD diagnosis. PATIENTS AND METHODS The clinical charts of 418 patients with CD and 705(More)
BACKGROUND We measured anti-transglutaminase (anti-tTG) antibody in the culture medium of intestinal biopsy specimens from patients with suspected celiac disease (CD) and evaluated the relationship between antibody production and severity of intestinal mucosal damage. METHODS We performed diagnostic testing for CD on 273 consecutive patients. In addition(More)
BACKGROUND Although anti-endomysial antibodies (EmA) have been found in the supernatants of cultured intestinal mucosa from patients with coeliac disease (CD), in no study has the clinical reliability of this new diagnostic tool been investigated. Our aims were to evaluate the clinical usefulness of the in vitro production of EmA in CD diagnosis in(More)
AIM To investigate the association of cyclooxygenase-2 (COX-2) expression with angiogenesis and the number and type of inflammatory cells (macrophages/Kupffer cells; mast cells) within primary hepatocellular carcinoma (HCC) tissues and adjacent non-tumorous (NT) tissues. METHODS Immunohistochemistry for COX-2, CD34, CD68 and mast cell tryptase (MC(T)) was(More)
