    Abstract:
    The aim of this study was to evaluate the effect of early prophylactic caffeine treatment on white matter development in very preterm infants using cerebral magnetic resonance imaging. A total of 194 preterm infants (≤32 weeks gestational age) were randomly assigned to the caffeine (n = 96) or placebo (n = 93) treatment group and administered with either caffeine or placebo within 72 h after birth. Cerebral magnetic resonance imaging, including diffuse tensor imaging examination, was performed at 34-36 weeks of corrected gestational age, and the fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values were measured. In total, 160 infants were included in the final analysis, including 80 cases in the placebo group and 80 cases in the caffeine group. There were fewer instances of apnea of prematurity and shorter assisted ventilation times for infants in the caffeine group compared to the placebo group (p < 0.05). Infants in the caffeine group had significantly higher FA values in white matter, including the posterior limb of the internal capsule, the corpus callosum, the frontal, occipital, and parietal white matter, the cerebellum, and the cerebral peduncle, compared to infants in the placebo group. ADC values in the above white matter areas were significantly reduced in the caffeine group. However, there were no significant differences regarding the FA and ADC in the gray matter between the two groups. These results demonstrate that early administration of caffeine improves white matter micro-structural development in preterm infants, but with no significant effect on short-term complications related to prematurity.
