Teratogenetische und mutagenetische Untersuchungen mit Coffein im Tierexperiment

Most of the population of the world is exposed to caffeine to a greater or lesser extent since it occurs in a number of plants used in the preparation of widely consumed drinks, and has in addition a limited therapeutic use. Chromosomal abnormalities are induced by caffeine in both plant cells and in mammalian cells in culture and it also has some anti-mitotic activity. DNA-repair processes sensitive to caffeine have been demonstrated in a number of cell systems and it has been shown to affect a wide range of other cellular processes. Caffeine has potent mutagenic effects in Escherichia coli and other micro-organisms both when acting alone and in combination with other mutagens. However its mutagenic activity in Drosophila has been disputed and the available evidence suggests that it is neither mutagenic in mammals nor synergistic with other mutagens although at very high doses it appears to have some teratogenic activity in mammals.

A population group consisting of 800 households of women who recently had been pregnant was surveyed to determine the level of consumption of a variety of beverages. Three fourths of the subjects were Mormon. Of a subgroup of 16 women identified as having an estimated daily intake of caffeine of 600 mg or greater, 13 had experienced a reproductive loss in the form of spontaneous abortion (eight) or stillbirth (five), two had given birth to premature infants, and only one had had an uncomplicated delivery. An inordinately high rate or reproductive loss also was noted in 13 households where the man's estimated daily intake of caffeine was greater than 600 mg. A cause-and-effect relationship cannot be determined by this type of retrospective study, but physicians should keep in mind the possibility that an excessive intake of caffeine may be a factor in otherwise unexplainable spontaneous abortion or perinatal mortality.
