Objectives: Methylxanthines, including theophylline, have been used extensi
vely and successfully to treat apnoea in preterm infants. However, long-ter
m consequences of such therapy are largely unknown. The aim of this study w
as to determine the relationship between theophylline therapy and outcome a
t 14 years of age in surviving preterm children of birthweight < 1501 g.
Methodology: The subjects of this study were 154 consecutive survivors with
birthweights < 1501 g bon from 1 October 1980 to 31 March 1982, 130 (84.4%
) were assessed at 14 years of age. Outcomes included motor function, psych
ological test scores, and growth.
Results: Of the 130 children assessed, 69 (53.1%) had been exposed to theop
hylline; 13.0% had cerebral palsy, significantly higher than 1.6% in the 61
children not exposed to theophylline (P < 0.02). This difference remained
statistically significant after adjusting for potential confounding variabl
es including the presence of cerebroventricular haemorrhage. In contrast, a
fter adjusting for known confounding variables, children who had received t
heophylline achieved higher psychological test scores. Then was no associat
ion between theophylline therapy and growth.
Conclusions: Theophylline therapy in the newborn period is associated with
some evidence of harmful, but also helpful sensorineural effects at 14 year
s of age.
