Despite development of many prevention and treatment modalities for bronchopulmonary dysplasia (BPD), a form of chronic respiratory insufficiency in premature infants recovering from respiratory distress syndrome, BPD remains a treatment challenge and a significant cause of long-term morbidity. A ventilator-dependent very low birth weight infant in our newborn special care unit was receiving multiple courses of systemic dexamethasone for severe respiratory failure. The infant demonstrated adrenal suppression manifested by a baseline cortisol concentration below reported levels in infants of similar birth weight and postnatal age. We hypothesized that he had developed adrenal insufficiency as a result of the prolonged systemic steroid administration used to treat his respiratory problems. We further hypothesized that inhaled beclomethasone therapy would aid in the infant's recovery phase during relative adrenal insufficiency--and so substituted inhaled for systemic steroids. Inhaled corticosteroid treatment improved the clinical respiratory course and postnatal growth of this premature infant with BPD without inhibiting his recovery from adrenal insufficiency.
尽管针对支气管肺发育不良(BPD)已开发出多种预防和治疗方法,BPD是呼吸窘迫综合征恢复过程中早产儿出现的一种慢性呼吸功能不全形式,但它仍然是一个治疗难题,也是长期发病的重要原因。我们新生儿特别护理病房中有一名依赖呼吸机的极低出生体重婴儿,因严重呼吸衰竭接受了多疗程的全身性地塞米松治疗。该婴儿表现出肾上腺抑制,其基线皮质醇浓度低于出生体重和出生后年龄相似的婴儿的报告水平。我们推测,由于用于治疗其呼吸问题的全身性类固醇药物使用时间过长,他出现了肾上腺功能不全。我们进一步推测,吸入倍氯米松治疗将有助于该婴儿在相对肾上腺功能不全期间的恢复阶段——因此用吸入类固醇替代了全身性类固醇。吸入皮质类固醇治疗改善了这名患有BPD的早产儿的临床呼吸进程和出生后生长情况,且未抑制其从肾上腺功能不全中恢复。
