Three cases of severe anorexia are reported. It results in a strong protein malabsorption with hepatic steatosis and in a syndrome of mental depression which needed the re-establishment of the intestinal-continuity. Although a mild post-operative anorexia is regular and contributes to the weight loss, massive anorexia must be considered as a new and redoubtable unpredictible complication of the surgical treatment for obesity, which may hinder the intestinal adaptation and increase the protein malabsorption.

General evidence of malnutrition such as loss in body weight associated with intestinal parasitism has been attributed to decreased food intake, to intestinal malabsorption, and to change in host basal metabolism. To establish the relative importance of these factors in this regard, rats with trichinosis were studied. The weights of infected and uninfected animals were followed after being placed on one of three feeding regimens for 1 week--stock diet ad libitum, intraduodenal nutrition, and intravenous nutrition. Infected rats on a stock diet lost weight whereas those on the other two regimens maintained the same weight pattern as uninfected counterparts. The maintainance of body weight occurred despite alterations at the level of the intestinal brush border as indicated by a depression of intestinal disaccharidase activities (sucrase and lactase) and by reduction of monosaccharide absorption (measured as accumulation of beta-methyl glucoside) in the proximal, heavily infected region of the small intestine. There was no compensatory increase in enzyme activity nor in the absorptive capacity in the distal gut. Results support the conclusion that inadequate oral food intake rather than changes in basal metabolism or intestinal pathophysiology accounts for weight loss during the intestinal phase of infection.

Using a 2-hour 47Ca absorption test, significant depression of active calcium absorption was demonstrated in 48 vitamin D untreated haemodialysis patients. This malabsorption of calcium could be corrected by the daily oral administration of 1--2 microgram of 1alphaOHD3 and 1--1.5 microgram of 1,25(OH)2D3. 5 microgram daily for 2 weeks of 3-deoxy-1alphaOHD3 AND 16 and 64 microgram daily for 1 week of 24R,25(OH)2D3 proved ineffective. In 32 successfully transplanted patients, restoration of normal or near normal renal function (serum creatinine less than 1.9 mg/100 ml) was not always followed by an immediate improvement in active calcium absorption. Calcium absorption, especially in female patients, was adversely affected by the required immunosuppressive prednisone therapy and improvement was slow.

The effect of a new complex oligosaccharide exhibiting potent inhibitory action on alpha-glucoside hydrolases on intestinal absorption of sucrose in man was tested by constant in vivo perfusion of the jejunum. At concentrations of 4.65 or 15.5 X 10(-6)M the alpha-glucosidehydrolase inhibitor (alpha-GHI) markedly inhibited absorption of glucose from sucrose and absorption of sodium and water. Oral administration of the alpha-GHI resulted as well in depression of solute, sodium, and water absorption. This new compound can serve as an interesting tool to induce carbohydrate malabsorption by inhibition of final digestion and may possibly be of beneficial therapeutic effect in dietary control of diabetes or obesity.

Food intake, appetite and a variety of feelings were measured pre- and post-operatively in obese patients undergoing jejuno-ileal bypass surgery. Decreased food intake correlated closely with the amount of weight loss at both 4 and 30 months after surgery. Malabsorption correlated with weight loss at 4 months but not 30 months post-operatively. The cause of the decreased food intake is unknown and cannot be completely explained by either depression, nausea, malabsorption, liver disease, an attempt to avert diarrhoea, or decreased appetite.

Nine patients with malignancy requiring chemotherapy were evaluated before, during, and in the recovery phase of their antineoplastic regimen with selected absorptive studies and jejunal biopsies. Depression of the crypt mitoses occurred without change in the indices of absorption. The mitotic indices returned to pretreatment counts on the recovery phase biopsies. Even after prolonged therapy, restudy in three of the patients failed to demonstrate clinical malabsorption. We conclude that chemotherapy-related malabsorption does not contribute to overall malnutrition of cancer patients during the first months of treatment.

Food intake was measured in 22 obese patients before and after jejunioleostomy for obesity. Most of the weight loss could be accounted for by the observed reduction of caloric intake. Malabsorption was also present as indicated by increased loss of fat in the stools, and decreased absorption of D-xylose and vitamin B12. A dislike for sweet tastes developed after surgery in most patients. Preferences for concentrated solutions of sucrose and glucose were reduced after patients showed a depression of food intake by a 440-calorie preload which had not been detected before surgery. These studies show a decrease in food intake after intestinal bypass surgery and suggest a role for taste or other gastrointestinal factors in regulating food intake.

Lactase deficiency, manifested clinically by lactose malabsorption, is often the only biochemical evidence of a residual disturbance of jejunal mucosal function after Escherichia coli enteropathy in the infant. Villous morphology is usually normal. A sustained depression of the processes of biochemical differentiation of lactase biosynthesis has been postulated to explain similar states of lactase deficiency, but a possible influence of altered epithelial cell turnover on the mucosal lactase levels has not been investigated. In ten infants with a residual lactose malabsorption, after E. coli infection, jejunal cell renewal activity and disaccharidase activities were studied by analysis of the exfoliated cells collected by lumenal perfusion. Significant increases in DNA and protein exfoliation and in the brush border activities of sucrase and lactase were observed during recovery from the malabsorptive disturbance. DNA and protein efflux increased almost linearly during a 20-day period. Lactase was initially four times more deficient than sucrase activity in the exfoliated cells. Both enzyme activities increased at almost identical rates. Therefore, it took longer for lactase activity to return to normal levels. The lactase/sucrase ratios approached normal at the end of the 20-day period. The changes in the exfoliating levels of the two enzymes, when analysed in relation to the increases in cell renewal activity, suggested a relationship between sucrase and lactase levels and cell age.

It is possible to reduce side effects of oral contraceptives by individualizing the dosage and type of pill on the basis of such factors as length and regularity of normal cycle and sensitivity to endogenous progesterone, as demonstrated by premenstrual tension and depression. Tailor-made pills would provide dosages of either estrogen, progesterone, or a combination, calculated on the amount that is necessary to control the ovulatory cycle and subsequently adjusted for any observed side effects. The choice of estrogen or progesterone shoul d be based on a careful medical history that takes all relevant factors into consideration. Most marketed oral contraceptives are combinations designed to contain the minimum effective dosage; however, they must also compensate for such influences as short cycles, malabsorption, and inconsistency in taking the pills. These factors can be dealt with better on an individual basis by the practitioner's prescription of doses based on medical history. This practice may be considered threatening by pharmaceutical companies, but physicians must avoid marketing pressures and concentrate on optimal treatment of individual patients.

The fatty acid pattern of blood serum lipids was examined by gas liquid-chromatography in 30 cases with bilharzial hepatic fibrosis, 11 cases with chronic active hepatitis accompanied by jaundice, and 28 healthy individuals as a comparison group of the same socioeconomic class of patients. In addition, the fatty acid patterns of the three major serum lipid classes, namely: cholesterol ester, phospholipids and triglycerides, were also investigated in seven cases of each group by gas liquid chromatography. The most remarkable differences were: a depression of the essential fatty acid level (linoleic and arachidonic) in both groups of patients together with a concomitant elevation of oleic acid in the bilharzial group and an elevation of oleic, palmitic, palmitoleic acids in the chronic active hepatitis group. The depression of linoleic and arachidonic acids was explained by the low fat diet intake, malnutrition, and the malabsorption factors which were frequent in all the patients studied. The elevation of monoethenoid acids was attributed to the decrease in the ability of the liver to desaturate the endogenous saturated and monounsaturated acids to polyunsaturated ones.
