Pantothenic acid deficiency induced in human subjects.

چکیده
Bean and Hodges (1) gave a preliminary report of four young men in whom clinical disorders and metabolic faults were induced by a "diet" devoid of pantothenic acid, with omega-methylpantothenic acid, a vitamin antagonist (Figure 1). It is proposed here to describe details of the experiments, results, and some interpretations. The background for using molecular antagonists (2, 3) in human nutrition had been explored previously using antagonists to nicotinic acid (4). Among the accepted B-complex vitamins, pantothenic acid has been most puzzling in human nutrition. Its discovery by Williams, Lyman, Goodyear, Truesdail, and Holaday (5) and its presence in coenzyme A (6) suggested metabolic functions in man. Its employment in treating undernourished persons yielded no clue. Data from experimental animals revealed that the principal manifestations of its deficiency are those of adrenal cortical failure, accompanied by low plasma cholesterol, gastrointestinal symptoms and lesions, impaired antibody production, neurological lesions and alterations of the epidermis (7-11). The function of pantothenic acid in animals has been clarified by Drell, Dunn and their co-workers (1215) who synthesized omega-methylpantothenic acid, demonstrated that it antagonized pantothenic acid, determined its toxicity in animals and showed that its deleterious effects could be reversed or prevented by pantothenic acid. Some of these observations were verified and extended by Shils (16).

Metabolic response to a pantothenic acid deficient diet in humans.
The responses of human subjects to a low pantothenic acid test diet and to the same diet supplemented with 10 mg pantothenic acid daily for 63 days were observed. Pantothenic acid in urine and blood and also nitrogen balance were used as criteria for nutritional evaluation. The mean daily urinary pantothenic acid excretion decreased from 3.05 to 0.79 mg in male adult subjects fed a pantothenic ...
متن کاملVitamin D deficiency changes the intestinal microbiome reducing B vitamin production in the gut. The resulting lack of pantothenic acid adversely affects the immune system, producing a “pro-inflammatory― state associated with atherosclerosis and autoimmunity
Study objectives: Vitamin D blood levels of 60–80 ng/ml promote normal sleep. The present study was undertaken to explore why this beneficial effect waned after 2 years as arthritic pain increased. Pantothenic acid becomes coenzyme A, a cofactor necessary for cortisol and acetylcholine production. 1950s experiments suggested a connection between pantothenic acid deficiency, autoimmune arthritis...
متن کاملSystemic lupus erythematosus: a combined deficiency disease.
To date, the pathogenesis of systemic lupus erythematosus (SLE) remains unclear. By critically analyzing clinical facts and laboratory data, a hypothesis is proposed: drug-induced lupus erythematosus (DILE) is linked to a deficiency in Coenzyme A (CoA) that is secondary to a deficiency in pantothenic acid. This hypothesis is used to explain the high incidence of SLE in females, the role of sex ...
متن کاملThe modification of choline deficiency by simultaneous pantothenic acid deficiency.
It was found recently (1) that feeding a cholesterol-rich diet to pantothenic acid-deficient rats did not result in the fatty livers and high levels of cholesterol in liver and serum seen in comparable animals maintained on a normal diet. Decrease in food intake appeared not to account for this phenomenon, since the food intake of the deficient group on a body weight basis was higher than that ...
