OBJECTIVE Environmental factors driving the development of type 1 diabetes (T1D) are still largely unknown. Both animal and human studies have shown an association between altered fecal microbiota composition, impaired production of short-chain fatty acids (SCFA) and T1D onset. However, observational evidence on SCFA and fecal and oral microbiota in adults with longstanding T1D vs healthy contr...
BACKGROUND Fecal lactoferrin has been introduced as a useful tool for the diagnosis and monitoring of inflammatory bowel disease (IBD). The aim of this study was to assess if fecal lactoferrin can be employed to predict or estimate the effect of granulocyte and monocyte adsorptive apheresis (GMA) in ulcerative colitis (UC). METHODS This was a prospective study involving 21 patients with UC. P...
OBJECTIVE Exocrine pancreas dysfunction is seen in 10-30% of patients with type 1 and 2 diabetes. We have recently identified a syndrome of diabetes and exocrine pancreas dysfunction attributable to mutations in the carboxyl ester lipase (CEL) gene. We wanted to investigate the prevalence of pancreatic exocrine dysfunction in patients with maturity-onset diabetes of the young type 3 (MODY3). ...
Bile acid excretion was studied in 9 human subjects simultaneously by the Lindstedt (Lindstedt, S. 1957. Acta Physwl. Scand. 4O:l-9) isotopic turnover method and by fecal chemical analysis during a balance study. The identities of the fecal bile acids were confirmed by combined gas-liquid chromatography /mass spectrometry. Under the steady state conditions of the patient studies, bile acid excr...
Despite efforts to minimize fecal input into waterways, this kind of pollution continues to be a problem due to an inability to reliably identify nonpoint sources. Our objective was to find candidate source-specific Escherichia coli fingerprints as potential genotypic markers for raw sewage, horses, dogs, gulls, and cows. We evaluated 16S-23S rRNA intergenic spacer region (ISR)-PCR and repetiti...
Dietary polyphenols, including red wine phenolic compounds, are extensively metabolized during their passage through the gastrointestinal tract; and their biological effects at the gut level (i.e., anti-inflammatory activity, microbiota modulation, interaction with cells, among others) seem to be due more to their microbial-derived metabolites rather than to the original forms found in food. In...
