SYNOPSISWe studied the effect of acute tryptophan (TRP) depletion in a group of eight abstinent bulimic (BN) subjects and in 12 healthy female controls. Despite being free of episodes of bingeeating and vomiting for a prolonged period, the abstinent BN subjects still appeared to practice dietary restraint as judged by their food intake in a test meal. In addition, their plasma TRP concentrations were significantly lower than those of the controls. Administration of a TRP-free amino acid load (52 g) significantly lowered plasma total and free TRP. However, compared to a balanced amino acid load, this procedure did not have significant effects on mood, appetite or food intake in either the abstinent BN subjects or the healthy controls.

SUMMARY The effect of alterations in catecholamine metabolism on arginine-induced insulin release was studied in the anaesthetized rat. Alpha-methyl-p-tyrosine, which inhibits catecholamine synthesis, guanethidine, which prevents catecholamine release, and reserpine, which depletes catecholamine stores, all enhanced the secretion of insulin and reduced the rise in blood glucose after the amino acid load. Adrenalectomy, with or without corticosterone replacement, had a similar effect. Adrenaline inhibited the insulin response to arginine. It was concluded that in the rat, adrenergic mechanisms modulate the insulin response to arginine.

Load Tests

An 18-month-old boy with repeated episodes of vomiting, lethargy, irritability, acidosis, and hypoglycemia from the age of 2 months was proved to have a variant form of maple syrup urine disease (MSUD). Amino acid load tests for leucine, isoleucine, valine, and phenylalanine were performed and compared to similar tests in a child with classic MSUD; maximum serum concentrations during tolerance studies in our patient were 24, 16, 26, and 18 mg/dl, respectively. All amino acid challenges were tolerated well except for valine. Within one hour after valine administration the child developed symptoms of lethargy, vomiting, ataxia, irritability, and hypoglycemia. Cortisol, growth hormone, insulin, and glucagon response to hypoglycemia were normal. Filbroblasts studies on cultured cells from our patient demonstrated abnormally low rates of 14CO2 production from both 14C-labeled leucine and 14C-labeled valine. Decarboxylation with valine as substrate was significantly less than the decarboxylation with leucine. A proteinrestricted diet was started but he continued to have occasional symptomatic episodes of hyperaminoacidemia and at the age of 4 years died during one of these episodes. Results of neuropathologic studies differed from those reported in the literature for classic MSUD disease.
