The levels of beta-endorphin, insulin, cortisol, GH, glucagon, prolactin and TSH were measured in serum samples of 9 hyperglycaemic patients (3 female, 6 male) with a mean age of 4.1 years admitted to the pediatric emergency unit. All patients were in acute stress due to severe diseases (acute gastroenteritis, bronchopneumonia, septicaemia, etc.). Initial and repeat blood samples for hormone determination were taken at admission and in the recovery phase (after 4-6 weeks of treatment). OGTT was also performed in the recovery phase. The hyperglycaemia, monitored hourly following the initial determination, returned to normal in all patients in 1-5 h without specific treatment. Mean serum glucose values at admission and in the recovery phase were 287.0 and 84.1 mg/dl. Concomitant to the hyperglycaemia encountered in these patients in the acute phase of stress, an increase was noted in all hormone levels excluding glucagon and cortisol. All elevated hormone levels fell to normal in 4-6 weeks with significant differences from initial levels for beta-endorphin (P < 0.05) and insulin (P < 0.01). OGTT gave a normal curve. These results indicate that stress hyperglycaemia, despite high insulin levels, is associated with an increase in beta-endorphin levels. The results also show that hyperglycaemia in acute disease does not alter OGTT in short-term follow up.

Gastroenteritis is one of the risk factors for developing irritable bowel syndrome (IBS). However, the precise mechanism of postinfectious IBS is still unknown. We tested the hypothesis that a combination of previous inflammation and repetitive colorectal distention (CRD) makes the colon hypersensitive and that treatment with a corticotropin-releasing hormone receptor 1 (CRH-R1) antagonist blocks this colonic hypersensitivity. Rats were pretreated with vehicle or 2,4,6-trinitrobenzene sulphonic acid (TNBS) 6 weeks before CRD. For the CRD experiment, the colorectum was distended once a day for six consecutive days. The CRH-R1 antagonist (CP-154,526, 20 mg kg(-1)) or vehicle was injected subcutaneously 30 min before CRD. Visceral perception was quantified as visceromotor response (VMR) using an electromyograph. For histological examination, the rats were killed on the last day of CRD experiment, and haematoxylin and eosin-staining of colon segments was performed. Although from the first to the third day of CRD, VMRs increased in both the vehicle-treated rats and TNBS-treated rats, they were significantly higher in TNBS-treated rats than those in vehicle-treated controls. On the fifth day of CRD, however, VMRs in the vehicle-treated rats were significantly greater than those in TNBS-treated rats. Pretreatment of rats with CP-154,526 significantly attenuated the increase in VMR induced by repetitive CRD with previous inflammation. Finally, we found that repetitive CRD and repetitive CRD after colitis induced visceral inflammation. These results indicate that a combination of previous inflammation and repetitive CRD induces visceral hypersensitivity and that a CRH-R1 antagonist attenuates this response in rats.
