2. Pathogenetic mechanisms in irritable bowel syndrome
Abstract : Aims of the thesis: To study new pathogenetic mechanisms in IBS; to find out if IBS is a neuromuscular disease affecting the small bowel; to study humoral factors in gut dysmotility associated with visceral neuropathy; and to study the natural history of post-infectious gastro-intestinal (GI) symptoms and risk factors for their development.

4. The Significance of IgG Antibodies against Tissue Transglutaminase in Coeliac Disease
Abstract : Coeliac disease (CD) is a multifactorial disease of the small intestine. In genetically predisposed individuals the, ingestion of cereals leads to a remodulation of the mucosal architecture, and the production of autoantibodies against tissue transglutaminase (tTG).

Celiac disease is characterized by an inflammatory infiltrate of CD4+ T lymphocytes in the intestinal mucosa leading to damage of villous structure and loss of absorptive surface. READ MORE
