Serum motilin in gastrointestinal diseases.

In order to investigate the possible involvement of gastrointestinal hormones in functional disorders of the digestive tract, serum motilin, neurotensin and gastrin levels in their response to oral intake of fat and glucose were examined in patients with irritable colon syndrome and dumping syndrome. The following results were obtained. (1) Basal serum motilin levels were higher in patients with irritable colon syndrome than in normal subjects, and remained high after ingestion of either 50 g of butter or 50 g of glucose. (2) No consistent response in serum neurotensin levels was found in patients with irritable colon syndrome or in normal subjects. (3) An immediate increase in serum gastrin levels was found in response to fat ingestion both in patients with irritable colon syndrome and in normal subjects, but there was no difference between these two groups. (4) In a patient with typical dumping syndrome, a markedly high level of fasting serum motilin was found, and the level increased further after the oral intake of glucose. These findings suggest that motilin may be involved in the irritable colon syndrome and dumping syndrome.

Retrospective evaluation of repeat celiotomy in 53 horses with acute gastrointestinal disease.

Fifty-three of 648 horses (8.2%) treated surgically for acute gastrointestinal obstruction were subjected to repeat celiotomy. Forty horses (75%) recovered from anesthesia after repeat celiotomy, and 26 horses (49%) were discharged from the clinic. Excluding two horses lost to follow-up, 10 of 51 horses (20%) survived long term. Horses subjected to repeat celiotomy had a significantly lower long-term survival rate than horses subjected to a single celiotomy. Twenty-eight horses had mechanical obstructions, and 22 had functional obstructions at the second surgery. Significantly more horses with mechanical obstructions recovered from anesthesia, but there was no difference in short-term or long-term survival. Seventy-seven percent of horses were subjected to two celiotomies without being discharged from the clinic between procedures. The intervals between primary and repeat celiotomies ranged from less than 24 hours to 4 years, with 89% of them being less than 2 months. Horses with functional obstructions at the second surgery had a significantly shorter interval between surgeries than horses with mechanical obstructions. Twenty-three horses had sequelae of the primary celiotomy, 19 had progression of their original disease, 8 had recurrence of the same condition, and 3 had unrelated problems. Intestinal ischemic necrosis was the most common diagnosis at repeat celiotomy, and small intestinal obstruction by adhesions was the second most frequent.

Clinical significance of cytomegalovirus (CMV) antigenemia in the prediction and diagnosis of CMV gastrointestinal disease after allogeneic hematopoietic stem cell transplantation.

To evaluate the clinical significance of a cytomegalovirus (CMV) antigenemia assay in the prediction and diagnosis of CMV gastrointestinal (CMV-GI) disease after hematopoietic stem cell transplantation (HSCT), 19 allogeneic HSCT recipients developing CMV-GI disease were retrospectively reviewed. All patients were monitored by a CMV antigenemia assay, at least once weekly after engraftment. The median onset of CMV-GI disease occurred 31 days post transplant (range: 19-62). Only four of 19 patients (21%) developed a positive CMV antigenemia test before developing CMV-GI diseases. Although all 19 patients subsequently developed positive CMV antigenemia tests during their clinical courses, the values remained at a low-level in nine (47%) patients. Among the 14 patients in whom results of real-time polymerase chain reaction (PCR) were available, seven (50%) yielded positive results of real-time PCR before developing CMV-GI disease. In contrast to the values of CMV antigenemia, all 14 patients exclusively yielded high viral loads (median: 2.8 x 10(4) copies/ml plasma). We conclude that CMV antigenemia testing has limited value in prediction or early diagnosis of CMV-GI disease, and that real-time PCR could have a more diagnostic significance.
