title: [L-carnitine-betamethasone combination therapy versus betamethasone therapy alone in prevention of respiratory distress syndrome].
abstract: In this prospective randomised study the effects of antenatal treatment with a low dose betamethasone (2 mg/1 day)-L-carnitine (4 g/5 days) combination were compared with those of a high dose betamethasone, given alone (8 mg/2 days) on the prevention of respiratory distress syndrome (RDS) and mortality in preterm infants. One-hundred women entering the trial gave birth to 109 liveborn infants, 55 in the betamethasone group (A), 54 in the betamethasone-L-carnitine combination group (B). Eight of the 55 (14.5%) infants in group A developed RDS, four of the 54 (7.3%) in group B, which was significantly more (p < 0.05), although in group B the betamethasone dose was dramatically reduced. The mortality also was significantly lower after treatment with a betamethasone-L-carnitine combination compared to betamethasone alone (4 of 55 infants or 7.3% in group A versus 1 of 54 infants or 1.8% in group B, p < 0.05). The present results demonstrate that in combination with L-carnitine, the betamethasone dose is markedly reducible with a concomitant significant reduction of the incidence of RDS and mortality of premature newborns.
