Malignant complications of coeliac disease
ABSTRACT Patients with coeliac disease (CD), particularly those who are undiagnosed or do not adhere to a strict gluten free diet (GFD), are prone to develop complications. Malignant complications are the most serious and should be suspected when expected responses to GFD are not achieved or sustained. Lymphomas, mostly T-cell type, and other malignant tumours, particularly carcinoma of the small bowel, less frequently of stomach and oesophagus, are associated with CD. Loss of response to a gluten free diet (refractory coeliac disease) and ulcerative jejunitis are two recently described complications of CD that may progress to an Enteropathy-Associated T-cell Lymphoma (EATL). Coeliac disease-related lymphoma most often appears at extra-nodal sites, essentially the small bowel, although one have to realise that T-cell lymphomas arising in sites outside the small bowel could be related to coeliac disease. Workup of an EATL must include immunehistology and if necessary T-cell flow cytometry and T-cell rearrangement. Adequate imaging with CT and PET-scanning is mandatory.

ABSTRACT: Enteropathy-associated T cell lymphoma (EATCL) is an intestinal neoplasm of intra-epithelial T lymphocytes associated with coeliac disease. Although the incidence is rare, EATCL runs an aggressive disease course and produces multi-focal ulcerative lesions most commonly in the proximal small bowel. As such, patients may present with intestinal perforation, obstruction or haemorrhage. Management of EATCL requires a combination of early diagnosis and treatment by surgical resection followed by chemotherapy to achieve treatment success. Overall however, the treatment completion rate remains at 50% and EATCL carries a poor prognosis with a 5-year survival rate of <20%.03/2014; 2014(3). DOI:10.1093/jscr/rju013

ABSTRACT: Background and Aims. Hepatic hemangioma (HH) has a widely ranging prevalence. The etiology is unclear; however, associations with autoimmune disorders have been described. We aimed at evaluating the prevalence of HH in celiac disease. Methods. Ninety-seven consecutive patients with celiac disease (18 M, 79 F, median age 41, and range 17-84 years) underwent liver ultrasound between January 2011 and 2012. The findings were compared with those of 1352 nonceliac patients (581 M, 771 F, median age 50, and range 16-94 years), without liver disease or previously detected HH, who underwent US in the same period. Results. Ultrasonographic findings consistent with HH were observed in 14 celiac patients (14.4%), a prevalence significantly higher than in controls (69 cases, 5.1%) (P = 0.0006). Subgroup analysis showed that, among women, the prevalence of HH was 16.4% in the celiac disease group (13/79) compared with 5.9% in controls (46/771) (P = 0.002). In celiac setting, HH had a median diameter of 1.3 cm and presented as a single lesion in 12 cases (86%). Conclusions. Our findings are consistent with a significantly higher prevalence of HH in celiac patients. Although mechanisms underlying this association remain unclear, autoimmune and metabolic processes, as well as alterations of gut-liver axis equilibrium, could play a role.Gastroenterology Research and Practice 01/2015; 2015:1-6.

ABSTRACT: Introduction: refractory iron-deficiency anemia has a multifactorial origin related to various gastrointestinal conditions, with celiac disease plus malabsorption and IBD together with isolated gluten intolerance being most common. Objectives: to determine the prevalence of serum, genetic, and histological markers for gluten intolerance, and to analyze the response to gluten withdrawal from the diet in these patients. Methods: a number of patients with refractory anemia were prospectively and consecutively enrolled. A protocol to measure serum (TGt-2), genetic (HLA-DQ2/DQ8), and histological markers for celiac disease was applied. All followed a gluten-free diet for a median 3.6 years. Sustained remission of anemia during follow-up was interpreted as positive response. Results: ninety-eight patients (84% females) with a mean age of 54 years were studied. Anti-TGt2 antibodies were positive in 5% of cases. A total of 67 cases (68%) were haplotype HLA-DQ2 or -DQ8 (+). We found villous atrophy (Marsh III) in 13% of patients, and an inflammatory pattern (Marsh I or II) in 13%. All remaining 72 patients (74%) had no histological duodenal changes. Age, anemia duration, number of transfusions, number of parenteral iron doses, and time on a gluten-free diet were all compared according to the presence or absence of villous atrophy and HLA-DQ2/8 positivity, and no significant differences were found for any of the analyzed variables. Response was positive in 92% of subjects. Conclusions: celiac disease with villous atrophy is rarely a cause of refractory anemia. Gluten intolerance with no histological lesions is seen in almost 75% of patients, and therefore plays a relevant role in its development.Revista espanola de enfermedades digestivas: organo oficial de la Sociedad Espanola de Patologia Digestiva 07/2011; 103(7):349-354. · 1.32 Impact Factor
