Dietary fiber and blood lipids: reduction of serum cholesterol in type II hyperlipidemia by guar gum.

Guar gum, a storage polysaccharide galactomannan and a form of dietary fiber, was administered to 10 patients with type II a or b hyperlipidemia for 2 weeks. Five grams of gum was given before each of three meals daily, either in a specially prepared soup or mixed with fruit juice or milk. No other deliberate change of diet was made. Three patients had been taking 12 to 16 g/day of cholestyramine for more than 2 years and one had been taking 1000 mg of clofibrate daily. These drugs were continued throughout the trial. Serum cholesterol levels of all 10 patients had been stable for 6 to 18 months before the trial at the start of which the mean level was 345 +/- 15 mg/dl. After 2 weeks of guar gum the mean was 308 +/- 16 mg/dl, a fall of 10.6% (P less than 0.01). Serum triglyceride was not changed significantly. Guar gum, which can be incorporated into foods, merits further study as a potential hypocholesterolemic agent.

Effect of dietary fiber on complications of gastric surgery: prevention of postprandial hypoglycemia by pectin.

The dumping syndrome is a very troublesome problem to some patients after gastric surgery. Gel-forming carbohydrates have recently been used to modify glucose absorption. The addition of 14.5 g of pectin to a 50-g oral glucose load prevented the occurrence of hypoglycemic symptoms and maintained the blood glucose levels above control values by 64% at 90 min (P less than 0.002) and 46% at 120 min (P less than 0.01) in postgastric surgery patients whose 120-min values after 50 g of glucose alone had fallen below 50 mg per 100 ml (2.8 mmoles per liter). Breath H2 production, used as an index of bacterial fermentation of glucose, was abolished or reduced by pectin in all 5 cases in which this had previously occurred. A trial of 10 g of pectin per day prevented recurrent postprandial hypoglycemic attacks in the most severely affected individual. Pectin and perhaps other unabsorbable polysaccharides are likely to prove useful in the treatment of abnormal carbohydrate absorption after gastric surgery.

Serum immunoglobulins in multiple pregnancy.

The concentrations of immunoglobulins (Ig) G.A.M. and E were determined in paired umbilical cord and maternal sera in 50 twin pregnancies. Mean IgG levels were higher in cord than maternal sera and in most cases the cord IgG level related more closely to that of the other twin than to either maternal level or birthweight, and was in the range for singletons of the same gestational age. The three cases of fetofetal transfusion syndrome were exceptional in the large difference between IgG concentrations in recipient and donor twins. The discrepancy was much greater than that found between the levels of proteins produced by the fetus, suggesting a disturbance in maternofetal placental transfer. IgM was detected in all cord sera, with one exception, and the level was not related to order of birth. IgA was detected in 16% of cord sera, 13% in sera from first borns. IgE was detected in only 8% of cord sera and there was no evidence of placental transfer.
