1. It was shown that the water-soluble fraction of cow's milk and human milk did no possess significant antirachitic activity on rats.2. Whole cow's milk was found to contain 38 i.u. vitamin D/1. Whole human milk contained 15 i.u. vitamin D/1, of which 12 i.u. derived from the lipid fraction.3. Thus the values found were much lower than the 204 i.u./1 in cow's milk and 950 i.u./1 in human milk given in the literature based on chemical determination of the sterol sulphate content.

Sixty-nine premature infants receiving different dietaries and with birth weights below 2,000 gm were studied with chemical, clinical and radiologic methods. Vitamin D was given to all infants from the age of 4 days. The concentrations of calcium, phosphorus and phosphatase in the serum showed variations toward those seen in active rickets. These changes were somewhat more marked in infants fed human milk than cow's milk. Supplementation of human milk with dried skimmed cow's milk did not significantly alter these changes. Craniotabes was more frequently seen in premature infants fed human milk than cow's milk. Otherwise, no clinical signs of rickets were found. All the premature infants were born with a metaphyseal zone of rarefaction. These zones are believed to be the result of a disturbance in ossification which occured during the last weeks of pregnancy, perhaps caused by a factor which was also responsible for the premature birth. They gradually merge with the general osteoporosis developing 10 to 13 weeks after birth. Later, periosteal double contours are visible. These double contours are the first signs of an improved mineralization. There was no correlation between abnormal chemical findings and the most conspicuous radiologic or clinical findings. No case of recognizable rickets was observed among the infants studied. This risk of rickets, despite an adequate supply of vitamin D, is probably not as great as stated by previous investigators, and is probably the same whether the infants are fed human milk or cow's milk.

Breast Fed

I was happy to read the report from Greer et al.1 This biochemically confirms the clinical observation that the majority of children who develop clinical rickets are breast-fed. During the ten years, 1970-1979, I have seen six cases of clinical rickets. All of these infants were breast-fed.2 The only exception has been the rickets of prematurity. I should like to commend, again, the report from the Department of Pediatrics and Biochemistry of the University of Wisconsin.

Gastroduodenal Motility

It is known that breast milk empties more quickly from the stomach than does infant formula. We studied the difference in gastroduodenal motility between neonates fed with human milk and those fed with infant formula. Twenty-four five-to 36-day-old neonates were fed with mother's breast milk or with a cow's milk-based formula. Postprandlial gastroduodenal contractions were recorded manometrically for three hours. Repetitive, high-amplitude nonmigrating contractions were the dominant wave form during the postprandial period. The number of episodes, duration, amplitude, and frequency of nonmigrating contractions were not different following the different feedings. The migrating myoelectric complex, which signals a return to the interdigestive (fasting) state, appeared in 75% of breast milk-fed infants but only 17% of formula-fed infants (P < .05) within the three-hour recording period. Because contractions were similar following the two meals, but a fasting state recurred more rapidly in breast-fed infants, we conclude that factors other than phasic, nonpropagated antroduodenal contractions were responsible for the differences in gastric emptying between breast milk and formula.

Β Lactoglobulin

Previous studies have suggested that an unidentified cow's milk protein, other than β-lactoglobulin and casein, might play a pathogenetic role in infant colic. Therefore, a radioimmunoassay was used to analyze human breast milk and infant formula samples for the presence of bovine IgG. Milk samples from 88 of the 97 mothers tested contained greater than 0.1 µg/mL of bovine IgG. In a study group of 59 mothers with infants in the colic-prone 2- to 17-week age group, the 29 mothers of colicky infants had higher levels of bovine IgG in their breast milk (median 0.42 µg/mL) than the 30 mothers of noncolicky infants (median 0.32 µg/mL) (P < .02). The highest concentrations of bovine IgG observed in human milk were 8.5 and 8.2 µg/mL. Most cow's milk-based infant formulas contained 0.6 to 6.4 µg/mL of bovine IgG, a concentration comparable with levels found in many human milk samples. The results suggest that appreciable quantities of bovine IgG are commonly present in human milk, that significantly higher levels are present in milk from mothers of colicky infants, and that bovine IgG may possibly be involved in the pathogenesis of infant colic.
