Effect of motilin on gastric emptying in patients with diabetic gastroparesis.
    Gastroenterology, 1992, Volume: 102, Issue:1

    Erythromycin markedly accelerates gastric emptying, possibly because it acts as a motilin agonist. In the present study, the effect of an equipotent dose of motilin was tested. In six patients with severe diabetic gastroparesis, gastric emptying of liquids and solids was examined scintigraphically after motilin or placebo in a double-blind crossover study. Motilin (10 pmol.kg-1.min-1) or saline was infused over a 90-minute period starting 5 minutes before breakfast. Motilin markedly accelerated emptying. For liquids, the half-emptying time was reduced from 51 +/- 6 to 22 +/- 11 minutes (P less than 0.01) and for solids from 111 +/- 4 to 51 +/- 12 minutes (P less than 0.01). The mean increase in plasma motilin levels was 1315 +/- 342 pg/mL, corresponding to an effective infusion rate of about 4 pmol.kg-1.min-1. In the control experiments, basal motilin levels (173 +/- 17 pg/mL) were within the normal range but increased steadily postprandially, reaching 321 +/- 25 pg/mL at the end of the study period, probably reflecting gastric distension. The postprandial increase in pancreatic polypeptide level was blunted compared with accepted normal values but was more pronounced during motilin infusion, i.e., 650 +/- 217 vs. 279 +/- 66 pg/mL (P less than 0.01), probably because of the improved emptying. Our data show that motilin accelerates gastric emptying in diabetic gastroparesis and support the hypothesis that erythromycin's effect is mediated through motilin receptors.

Effect of erythromycin on gastric motility in controls and in diabetic gastroparesis.
    Gastroenterology, 1992, Volume: 103, Issue:1

    The effect of three doses of erythromycin on interdigestive gastrointestinal motility and on plasma motilin levels was studied in healthy volunteers and patients with diabetic gastroparesis. Abnormalities of interdigestive motility were observed in 40% of the patients. In healthy volunteers, 40 mg erythromycin elicited a premature phase 3 that started in the stomach. In contrast to the spontaneous gastric phase 3, this erythromycin-induced phase 3 was not accompanied by a motilin peak. In patients with diabetic gastroparesis, 40 mg erythromycin induced a premature phase 3 in three patients, no response in one patient, and a burst of antral contractions in another patient. Doses of 200 and 350 mg erythromycin elicited a burst of antral phase-3-like contractions in both volunteers and patients, which was not accompanied by a motilin peak. This phase-3-like activity did not migrate to the small intestine and was not followed by a phase 1, but by a prolonged period of antral contractile activity. The number and amplitude of antral contractions after 200 or 350 mg erythromycin were significantly higher than after 40 mg. The motor patterns induced by different doses of erythromycin offer potential therapeutic applications.

Effect of motilin on gastric emptying in patients with diabetic gastroparesis.
    Diabetes care, 1991, Volume: 14, Issue:1

    Because disturbances of gastric emptying are a serious complication in insulin-dependent diabetic subjects with regard to the maintenance of good metabolic control, we wanted to assess the effectiveness of motilin as a potential treatment for gastric emptying disturbances.. The intestinal hormone motilin has been shown to accelerate gastric emptying in healthy subjects. Therefore, we examined the effect of intravenous motilin on gastric emptying of a 99mTc colloid-labeled semisolid test meal in 9 insulin-dependent diabetic patients with diabetic gastroparesis. All patients had a significantly delayed gastric emptying rate compared with a group of 11 healthy control subjects.. During the infusion of motilin, gastric emptying was accelerated, and it was no longer significantly different from control values.. These data demonstrate that motilin and related compounds such as erythromycin derivatives could be useful for the treatment of disturbed gastric emptying in diabetic subjects.
