The objective of the study is to classify and carry out a quantitative analysis of the different bacterial species present in the intestinal microbiota of patients with acute pancreatitis and determine if there are significant differences regarding healthy controls. At the same time, the investigators pretend to determine if there are differences according to the etiology and severity of the disease and if the disregulation is temporary or is maintained after one month of discharge.
To carry out this purpose, the investigators have designed a prospective and multicentre observational study where samples of feces and saliva of patients admitted for acute pancreatitis of different etiologies and severity will be analyzed.
The study of the human microbiota is gaining importance given its relationship with the homeostasis of the organism as well as with certain pathologies. Specifically in the case of acute and chronic pancreatitis, recent studies suggest the disregulation of the intestinal flora as a possible determinant in the development and evolution of the disease. If this hypothesis is confirmed, hygienic-dietetic measures, as well as the administration of antibiotics, probiotics or fecal transplantation, may have therapeutic implications.

| Microbiota composition with respect to pancreatitis etiology assessed by clinical history and complementary tests. | Assessment of the different number of microbiological taxonomic groups and the proportion of them in fecal and salival samples from patients with different etiology of acute pancreatitis by mRNA sequencing and PCR amplification using Illumina sequency techonology. The pancreatitis etiology will be defined according to clinical history (e.g alcohol consumption, cholelitiasis, metabolic and inmune disorders) and complementary tests (US, CT scan and blood tests). |
