Abstract

The plasma half-life of theophylline was determined during and 1 month after serologically confirmed upper-respiratory-tract viral illness in six children with chronic asthma. In this group the plasma-theophylline half-life (mean = 419.8 min) was significantly longer during the acute stage of their illness than 1 month later (mean 249.9 min). There was no appreciable change in half-life in 4 patients who were febrile but in whom seroconversion did not occur. These preliminary results suggest that certain upper-respiratory-tract viral infections may affect theophylline metabolism.

摘要

在6名患有慢性哮喘的儿童中,测定了血清学确诊的上呼吸道病毒感染期间及感染后1个月时茶碱的血浆半衰期。在这组患儿中,疾病急性期的血浆茶碱半衰期(平均 = 419.8分钟)显著长于1个月后(平均249.9分钟)。4名发热但未发生血清转化的患儿的半衰期没有明显变化。这些初步结果表明,某些上呼吸道病毒感染可能会影响茶碱的代谢。
