The Precose Resolution of Optimal Titration to Enhance Current Therapies (PROTECT) study is an ongoing Phase IV clinical trial designed to assess the effectiveness, tolerability, and safety of acarbose tablets in patients with type II diabetes when the dosage is slowly titrated upward. This multicenter, open-label, 28-week trial will enroll approximately 7,000 type II diabetic patients. The present report describes the interim results for 2,139 patients who completed the trial as of November 1, 1996. Patients with type II diabetes enrolled in the study were inadequately controlled either with diet alone or with a sulfonylurea. The dosage of acarbose was titrated from 25 mg three times a day (TID) to 100 mg TID based on tolerability and efficacy. Efficacy of glycemic control was assessed by changes in glycated hemoglobin A1c (Hb A1c) and 1-hour postprandial plasma glucose (PPG) levels. Tolerability and safety were determined by patient reports of treatment-emergent adverse events and by review of laboratory tests. The PROTECT study confirms the previously demonstrated efficacy and safety of acarbose in improving glycemic control in patients with type II diabetes regardless of a patient's age, body weight, ethnic background, time since diagnosis, or severity of disease. mean 1-hour PPG levels declined throughout the entire treatment period, with a mean decrease from baseline of -47 mg/dL at the end of treatment. Hb A1c, the most reliable indicator of long-term glycemic control, decreased over the course of treatment, resulting in a mean decrease of -0.7% (P < 0.001). Although all patient types enrolled in the study responded positively to therapy, certain subgroups responded particularly well, such as those patients diagnosed with the disease less than 1 year ago, those treated with acarbose as monotherapy, and those with higher baseline Hb A1c levels. Adverse events were experienced by 36% of all patients and consisted primarily of gastrointestinal disturbances (flatulence, diarrhea, abdominal pain). Moderate renal insufficiency (serum creatinine levels between 1.5 and 2 mg/dL) was present in 259 patients, and no patients developed serum hepatic transaminase levels more than twice the normal range.

A nested case-control study was conducted in two trials of prophylaxis for Mycobacterium avium complex (MAC) infection to describe the specific signs, symptoms, and laboratory abnormalities of MAC disease in AIDS. Patients had < or =200/mm3 CD4 cells and a prior AIDS-defining illness. Of 571 patients, 102 (17.9%) developed MAC bacteremia during a mean follow-up of 256 days. Among cases of MAC disease, 90 were compared with 180 matched controls. Patients with MAC disease were more likely than controls to have lower weights (66.3 vs. 71.1 kg, P = .001) and Karnofsky scores (74.3 vs. 84.4, P < .001); a higher proportion had fever (48% vs. 26%, P = .003), abdominal pain (23% vs. 13%, P =.05), decreased hemoglobin levels (10.9 vs. 12.1 g/dL, P < .001), and elevated alkaline phosphatase (203 vs. 138 U/L, P=.04) and lactate dehydrogenase (334 vs. 280 U/L, P = .02) levels. Characteristics of MAC disease that occurred before bacteremia were weight loss (3 months prior), fever (2 months), and anemia and elevated lactate dehydrogenase (1 month). These data suggest that patients have symptomatic MAC disease for several months prior to the occurrence of bacteremia.

The present report concerns a patient who had undergone nearly total pancreatectomy (95%) with pancreatic islet autotransplantation for intractable pain caused by obstructive chronic pancreatitis. Islets were prepared by a modified collagenase digestion and were cultured in vitro in Eagel's medium in 5% CO2 in air at 37 degrees C for 5 days. The resultant preparation, containing about 150,000 islets, was injected into the recipient's liver via the umbilical vein. No complication occurred from the pancreatectomy or transplant. Postoperatively, the patient had complete relief of the abdominal pain, and the insulin-independent condition remained with normal fasting blood glucose, and hemoglobin A1c for 11 months. Subsequently the fasting hyperglycemia was evident, and the patient began oral antidiabetic medication, but 2 year after transplantation the insulin-dependent condition demanded exogenous insulin (24 U). At present the fasting serum C-peptide level is 0.6 ng/ml and the HbA1c of 5.8% confirms the normoglycemic condition at the same insulin dose. Islet auto-transplantation should be considered as an adjunct procedure to prevent or ameliorate diabetes after total or nearly total pancreatic resection.

A case of spontaneous rupture of the uterine artery in the third trimester of pregnancy is described. Review of the literature reveals only three similar cases. Clinical signs are sudden abdominal pain with hemodynamic collapse and a decrease in the level of hemoglobin. Treatment consists in performing a laparotomy with suturing of the ruptured artery.

A case is reported of a previously healthy 52-year-old African American male who presented with acute onset of abdominal pain. Progressive increase in his abdominal symptoms led to an exploratory laparotomy; however, no pathology was discovered. Postoperatively, the patient became hypoxemic which progressed to diffuse infiltrates on chest x-ray, suggestive of adult respiratory distress syndrome. He had a rapidly fatal course. Autopsy showed bone marrow infarction, fat embolism, splenomegaly, and widespread congestion with sickle erythrocytes. Hemoglobin electrophoresis done postmortem showed hemoglobin (Hb) SC disease that was undiagnosed antemortem. To the best of our knowledge, it is unusual for Hb SC to be diagnosed postmortem in adults. This case suggests that sickle cell disorders should be ruled out in patients at risk for hemoglobinopathy in the presence of signs and symptoms compatible with the disease, irrespective of age.

We encountered a patient with enterohemorrhagic Escherichia coli (EHEC) O157:H7 infection and secondary hemolytic uremic syndrome (HUS). The patient was a 79-year-old woman with hypertension, constipation, and asymptomatic cholelithiasis. She complained of nausea and abdominal pain, and had bloody stool EHEC O157 was detected by fecal culture. The bloody stool resolved after treatment with antibiotics, but the patient was hospitalized on July 23, 1996 because of abdominal distention. HUS was diagnosed because of proteinuria, hematuria, thrombocytopenia, hemolytic anemia, fragmentation of red blood cells, and increased serum LDH. Treatment was focused on plasma exchange, administration of antibiotics, large doses of gamma-globulin, haptoglobin replacement, and anticoagulation. Within about 2 weeks, the level of hemoglobin, the number of platelets, and the serum LDH had normalized, and the patient recovered from HUS. The decreased intestinal movement continued. On August 23, acute cholecystitis was diagnosed, and percutaneous transhepatic gall bladder drainage was done. Another exacerbation was noted on October 13, and cholecystectomy was done on November 12, when the patient's status had improved after instillation of antibiotics. Macroscopically, the gallbladder wall was thickened. Histopathological examination showed diffuse infiltration of lymphocytes into the mucosa, chronic cholecystitis was diagnosed. Because the postoperative course was satisfactory, the patient was discharged from the hospital on December 15. Acute exacerbation of chronic cholecystitis might have been caused by decreased cholic excretion after the marked decrease in intestinal movement due to O157 infection and secondary HUS. Because elderly people frequently have anamnesis of the digestive system, considerably attention should be paid to the management of anamnesis, as well as O157 infection and secondary HUS.

This paper describes a rare case of biliary atresia (BA) in which massive postoperative bleeding developed due to portal hypertensive enteropathy. A 15-year-old boy had been doing well after Kasai's operation for BA. At around the age of 6 years he developed recurrent episodes of esophageal variceal bleeding and underwent esophageal transection, splenectomy, sclerotherapy, and embolization of the left gastric vein. At the age of 15 years he suddenly developed abdominal pain, hematemesis, and massive tarry stools. His hemoglobin level was 6.3 g/dl. Endoscopy showed several small, polypoid lesions in the jejunum beyond Treitz' ligament. The source of the bleeding was one of these lesions located in the proximal jejunojejunostomy of the Roux-en-Y loop. Because he had repeated episodes of melena, he underwent partial resection of the jejunum under endoscopic guidance. He has since been free of gastrointestinal (GI) bleeding. From this experience, we conclude that the polypoid lesions of an enteropathy may be a cause of massive GI bleeding in the postoperative portal hypertension of BA.

Massive spontaneous hemoperitoneum has been infrequently presented in the literature. Only very seldom has this phenomenon been described without eventual discovery of an inciting event. We discuss a case of massive spontaneous hemoperitoneum in a 21-year-old healthy white male presenting with nausea, abdominal pain, and mild distention. There was a worsening in the degree of abdominal complaints since an initial evaluation by the Emergency Ward staff several hours before. The patient had no fever, vomiting, or other symptoms. He repeatedly denied trauma or memory of any potential precipitating event. The only pertinent laboratory finding was a drop in hemoglobin in the face of hemodynamic stability. Abdominal exploration revealed free intraperitoneal clotted blood without determination of definitive source of bleeding. No other abnormalities were found. A sound knowledge of potential causes of massive spontaneous hemoperitoneum in the nontraumatized patient with abdominal pain combined with a high index of suspicion and early operative intervention are keys to proper patient management.

A double-blind placebo-controlled study of the concurrent administration of albendazole and praziquantel was conducted in>1500 children with high prevalences of geohelminths and schistosomiasis. The study sites were in China and the Philippines, including 2 strains of Schistosoma japonicum, and 2 different regions of Kenya, 1 each with endemic Schistosoma mansoni or Schistosoma haematobium. Neither medication affected the cure rate of the other. There was no difference between the side effect rate from albendazole or the double placebo. Praziquantel-treated children had more nausea, abdominal pain, and headache but these side effects were statistically more common in children with schistosomiasis, suggesting a strong influence of dying parasites. The subjects were followed for 6 months for changes in infection status, growth parameters, hemoglobin, and schistosomiasis morbidity. In all 4 sites, a significant 6-month increase in serum hemoglobin was observed in children who received praziquantel, strongly supporting population-based mass treatment.

The authors report a case of beta-thalassemia/hemoglobin E disease with extramedullary haematopoietic tumor which developed at the small intestine and caused intussusception. A 7 year-old boy with homozygous beta-thalassemia/hemoglobin E presented with recurrent abdominal pain. The abdominal ultrasonography showed ileo-ileal intussusception with a solid mass as the leading point. Resection of the ileal segment was performed. Pathological examination revealed an extramedullary haematopoietic tumor forming an intraluminal polypoid mass, being the leading point of the intussusception. Extramedullary haematopoiesis in the intestinal tract is rare. To our knowledge, this is the first case of extramedullary haematopoietic tumor that produced intussusception of the small intestine in a beta-thalassemia/hemoglobin E patient.
