Predictive significance of serum levels of gastrointestinal hormones and cytokines for disease progression in patients with rotavirus diarrhea

AIM: To assess the early predictive value of serum levels of gastrointestinal hormones and cytokines in patients with rotavirus diarrhea.

METHODS: Serum levels of 5-serotonin, vasoactive intestinal peptide (VIP), gastrin (GAS), motilin (MOT) and cytokines (endothelin, IL-10) were determined by enzyme-linked immunosorbent assay (ELISA) in 65 children with severe, moderate or mild rotavirus infection during acute or convalescent phase and 60 normal healthy children.

RESULTS: Serum levels of 5-serotonin, VIP, GAS, MOT, and endothelin were significantly higher and that of IL-10 was significantly lower in children with rotavirus infection during the acute phase than in normal control controls (all P < 0.05). Serum levels of 5-HT, VIP, MOT, and endothelin were significantly higher in patients with severe rotavirus infection than in those with moderate or mild rotavirus infection (all P < 0.05). Serum levels of GAS and IL-10 showed no significant difference between patients with moderate rotavirus infection and those with mild disease (P > 0.05). Serum levels of 5-serotonin, VIP, endothelin and IL-10 were significantly higher in patients with acute phase rotavirus infection having diarrhea >3 d than in those having diarrhea <3 d (all P < 0.05), while GAS and MOT levels were not statistically significant between the two groups (both P > 0.05).

CONCLUSION: Pathophysiological changes in rotavirus diarrhea may be associated with the changes in serum levels of gastrointestinal hormones and cytokines. The relevant gastrointestinal hormones and cytokines may be used to predict rotavirus disease progression.

Methods for clinical evaluation of diabetic gastroparesis

An effective clinical assessment method is necessary for the development of new drugs. Currently, main methods for clinical evaluation of diabetic gastroparesis (DGP) include evaluation of gastric emptying, patients' subjective evaluation of disease severity and the change in pathogenic factors. However, there are many problems that need to address; the methods for the evaluation of gastric emptying have not been widely used, there is no uniform standard for the patients' subjective evaluation, and the pathogenic factors for DGP are not completely clear. In this article we will review the methods for clinical evaluation of DGP, with the emphasis on the above problems.
