PO14 FUNCTIONAL GASTROINTESTINAL DISORDERS IN INFANTS AND NEONATAL PERIOD: WHICH CORRELATION?

acute diarrhea. The initial clinical evaluation of the patients should focus on identifying likely causes on the basis of history and clinical findings. Blood routine analyses were performed upon admission in the hospital. Stool samples were obtained from all the children affected by gastroenteritis. All the specimens were tested for the presence of rotavirus antigens using validated ELISA test. Rectal swabs were cultured for Salmonella, Campylobacter and Shigella. We used Bayes’ theorem to establish ESR threshold level that could distinguish the two group of different causative agents of acute diarrhea. Results: Salmonella spp. grew in 27 samples, Rotavirus antigens were detected in 31 specimens. All the Children were culture-negative for Shigella and Campylobacter. 53% of patients with ID had ESR levels greater than mm. 29, 46% had levels lower. Only 5% of patients with NID had ESR values greater than mm 29. Using Bayes’ theorem, if ESR level is greater than mm 29, the probability that a patient with acute diarrhea has salmonellosis is 0.88. Conclusions: In our country the children admitted in hospital for AD with ESR levels higher than mm 29 have likely contracted salmonellosis.
