Nine patients underwent partial ileal bypass as management for heterozygous type II hyperlipidemia. The average age of this group was 12.5 yr. Follow-up has ranged from 1 to 6 yr. The growth and development of these children proceeded normally. The overall average serum cholesterol reduction was 33% when compared to the preoperative but postdietary control value. Side effects of the procedure include transient diarrhea and inability to absorb vitamin B12, requiring periodic parenteral administration. Partial ileal bypass has been shown to be an effective and obligatory method of treatment of hypercholesterolemia in children.

Small-bowel ischaemia is the least familiar cardiovascular complication of the oral contraceptive but is 1 associated with a high mortality rate and much morbidity. Hoyle et al have recently reviewed 21 cases and found that 1/2 the patients had died and 1/2 had required 2 or more operations, resulting in the removal of much of the small bowel. Small-bowel ischaemia occurs in women taking the oral contraceptive as a result of either mesenteric artery or mesenteric vein thrombosis. The dominant presenting symptom in small-bowel ischaemia, found in all patients, is abdominal pain. Some patients had associated nausea and vomiting; others complained of diarrhea. On examination the patient has usually been found to be febrile with generalized abdominal tenderness. Bowel sounds are present unless infarction has occurred. In nearly all cases reported the diagnosis has been made only at laparotomy, when the bowel was usually infarcted. Since many of the patients had had pain for 2 or more weeks, the condition might be reversible if it could be detected earlier. A diagnosis of small-bowel ischaemia should be carefully considered in any woman taking an oral contraceptive who presents with vague abdominal pain and has an associated condition known to predispose to circulatory disorders: cigarette smoking, hyperlipidaemia, diabetes, hypertension, obesity, or blood group A. If it seems like small-bowel ischaemia is the likely diagnosis, the contraceptive pill should be stopped immediately and treatment started with heparin.

The case histories and clinical findings of 15 ponies with hyperlipaemia are presented. The disease was characterised by hyperlipidaemia with inappetance, progressing somnolence, muscle fasciculation, diarrhoea, and ventral oedema as the predominant clinical findings. Post mortem examinations of 12 ponies showed extensive lipidosis and vascular thrombosis with widespread secondary changes. Most cases occurred in late pregnant and early lactating mares in the summer months and it is postulated that the disease was initiated in this group by a falling nutritional plane in the face of high nutrient requirements.

A case of chronic pancreatitis in an 8-year-old boy with glycogen storage disease type 1a (GSD 1a) is presented. This patient had a history of hyperlipidaemia unresponsive to dietary therapy, e.g., a carbohydrate-rich diet, uncooked cornstarch, and nocturnal intragastric tube feedings. He had recently suffered bouts of abdominal pain and diarrhoea. Serum amylase and trypsin were elevated, abdominal CT revealed the presence of a pseudocyst of the pancreas. The presence of chronic pancreatitis was confirmed by endoscopic retrograde cholangiopancreatography and an infected pseudocyst was removed at laparotomy.

To evaluate digestion, absorption and postprandial lipemia of diverse fats before and after fish oil capsule therapy (with ethylester) 20 healthy volunteers were recruited. A significant increase (p less than 0.001) in fecal fat excretion after fish oil capsule therapy, as well as serious diarrhoea after fat loads with 100 g of fish oil was noted. It was found, that under fish oil fat loads the total triglyceride content of the mucosa was significantly (p less than 0.001) lower compared to butter fat loads. Decrease digestion and absorption of omega-3 fatty acids was postulated.

The results are reported of a double-blind crossover trial intended to evaluate the effectiveness and safety of a new aryloxy derivative compared to placebo. Twenty patients with hyperlipidemia not responding to dietary treatment received either one capsule of the active substance or of placebo (200 mg) three times daily for 16 weeks. Total cholesterol, HDL and triglycerides showed the following changes at the of the treatment period: -11%, +6% and -48% with clinofibrate and -1%, -4% and -1% during control periods. The substance was well tolerated; only in one patient clinofibrate was withdrawn as a precaution in view of the onset of medium severe diarrhea and abdominal pain.

A total number of 30 native breed cows were used in this investigation. Ten animals were clinically healthy and kept as control, while 20 diseased cows were selected according to rectal findings. At the beginning of the disease, the cows appeared obese with marked deposition of fat in the subcutaneous tissue at the lumbosacral area, later on they became emaciated. Additional signs were digestive disturbance in form of diarrhea or constipation and tympany. Rectal examination revealed hard irregular masses of various size which were palpated in the pelvis, the perirenal area around the colon and the rectum. More information about the nature and character of the lesions were taken from slaughtered cows. Biochemical analysis, including total lipids, cholesterol triglycerides and creatine kinase, were carried out in both healthy and diseased cows. In advanced cases of bovine lipomatosis hyperlipemia and hypercholesterolemia as well as increased creatine kinase values were constant findings. The aetiology of this disease is still unknown.

A case of acute intestinal vascular necrosis in a 19-year-old user of oral contraceptives (OCs) is described, and hypotheses explaining the digestive complications of synthetic estrogens are reviewed. The patient had originally presented with a violent gastric pain that subsequently spread to the entire abdomen. An abrupt worsening of her condition involved cardiovascular collapse associated with a peritoneal syndrome, vomiting and dehydration, and hyperleukocytosis. Emergency opening of the peritoneum was followed by evacuation of a large quantity of fetid gas and alimentary debris, and observation of a completely necrosed stomach. A careful lavage of the entire intestinal cavity led to temporary improvement, but it became clear during an attempt at gastrectomy that further treatment would be unavailing and the patient died shortly thereafter. Estrogens were believed to be responsible for the digestive necrosis because it occurred in a young woman who had used an estrogen-rich OC for 3 years and who smoked; a hapatic biopsy confirmed the diagnosis. No traces of other risk factors such as hypertension, hyperlipidemia, diabetes, neoplasia, or obesity were observed. Recent publications indicate that OCs are responsible for a certain number of digestive problems, which may include acceleration of intestinal transit, severe diarrhea, rectorrhagia, ischemic or ulcerative colitis, intestinal infarct which is usually localized, and hepatocellular problems ranging from moderate hepatic insufficiency to malignant tumor and Budd-Chiari syndrome. OCs do not modify hemodynamic regimes, but they may cause elevation of fibrinogen and thrombin, diminution of antithrombin III acitivty, increased platelet adhesivity, and decreased fibrinolysis leading to hypercoagulability. These modifications in hemostasis occur in all OC users and are not statistically correlated with occurence of thrombotic accidents. OCs are probably responsible for parietal vascular lesions; experimental injection of synthetic estrogens is associated with both arterial and venous lesions. The most characteristic anomaly is at the level of the intima, with proliferation of smooth muscle cells and increased conjunctive tissue fibers associated with proliferation of the media or the endothelium. The absence of lipid deposits, the simultaneous appearance of arterial and venous lesions, and other evidence argues against and atheromatous origin of parietal lesions. A significant correlation has been found between high levels of anti-synthetic ethinyl estradiol antibodies and the presence of vascular lesions. It is hypothesized that these circulating immune complexes penetrate the vascular walls of OC users and produce lesions, which may depend on factors such as smoking.

The Program on the Surgical Control of the Hyperlipidemias (POSCH) was a randomized controlled clinical trial designed to ascertain whether cholesterol lowering induced by the partial ileal bypass operation would favorably affect overall mortality and the mortality and morbidity due to coronary heart disease. The trial results provided strong clinical and coronary arteriographic support for the beneficial effects of lipid modification for the reduction of atherosclerosis progression. At the same time, the surgery-assigned group experienced diarrhea and an increased incidence of kidney stones and gallstones compared to the control-assigned group. Identical quality of life determinations were performed in the POSCH study population shortly before disclosure of the trial results to the patients and shortly thereafter. The purpose of this dual assessment was to evaluate the effect of knowledge of outcomes on the patients' subjective evaluation of quality of life. The primary instrument utilized for analysis of the perception of quality of life in POSCH was the McMasters Health Index Questionnaire (MHIQ). In addition, four study-specific questions were asked of the trial patients. The results for the MHIQ before disclosure of trial results showed a difference (p = 0.07) favoring the control-assigned group (diet-treated), for the social function index of the MHIQ. After disclosure of the trial results, the difference was larger (p < 0.05). For the four study-specific questions, all differences favored the control-assigned group (p < 0.01) before and after disclosure of the trial results, with the exception of satisfaction with randomization allocation in the surgery-assigned group (p = 0.08). The intragroup MHIQ indices before and after disclosure of the trial results showed no suggestive significant differences, except in the surgery-assigned group, in which there was an improvement in the emotional function index after disclosure of the trial results (p = 0.03). The intragroup responses to the study-specific questions before and after disclosure of the trial results again showed no significant differences, except in the surgery-assigned group, in which there was an improvement in patient satisfaction with randomization allocation after disclosure of the trial results (p = 0.04).(ABSTRACT TRUNCATED AT 400 WORDS)

A 26-year old woman, who was diagnosed as having systemic lupus erythematosus at the age of 23 year old, presented diarrhea and headache. She showed severe hypoproteinemia (serum total protein 3.7 g/dl, serum albumin 1.4 g/dl) and hyperlipidemia. She revealed to have protein-losing enteropathy with the result of alpha-1-antitrypsin clearance test using stool. Increase of prednisolone improved the loss of albumin into the bowel and abnormal laboratory findings. She also showed watershed infarction in the area of middle cerebral artery and posterior cerebral artery. Protein-losing enteropathy is a rare complication of SLE, only 18 cases are available on literature. No case is found to have cerebral infarction in patients with protein-losing enteropathy associated with SLE. It is known that blood levels of anticoagulation factors decrease in protein-losing enteropathy due to the leakage of plasma protein into intestinal lumen. Serum antithrombin III was decreased in this case. Hyperlipidemia found in this case seems to be caused by same mechanism in nephrotic syndrome. Lupus anticoagulant was also positive in this patient. These factors seems to be related to the occurrence of cerebral infarction. This case suggests the possibility of cerebral infarction in patients with protein-losing enteropathy in SLE.
