Objectives N-acetylcysteine (NAC) has been shown to prevent hepatic damage and improve microcirculatory blood flow and oxygen delivery to the tissue. Previous studies have proposed the benefit of NAC in dengue-associated acute liver failure (ALF). However, most studies are descriptive and lack comparison between groups. We aimed to compare the ALF resolution rate and mortality rate of those who received and did not receive NAC treatment. Methods A retrospective cohort study was conducted among children aged <15 years who were diagnosed with dengue-associated ALF at a tertiary hospital in Thailand, between January 2002 and July 2019. Demographic and clinical information were collected. Main outcomes were ALF resolution and mortality rate. Results Thirty-three patients were included of which 16 received NAC treatment (48.5%). Mean ages were 8.5 years (SD 3.7) and mean onset of ALF was 6.3 days (SD 1.6) after onset of fever. The grading of hepatic encephalopathy (HE) and organ failure was not significantly different between the two groups. In the NAC group, 13/16 children were prescribed 100 mg/kg/day of NAC until INR <2 without HE or <1.5 with HE. NAC was initiated 1.1 days (SD 0.3) after the ALF diagnosis. The NAC group showed a higher rate of ALF resolution (75% vs. 53% in the non-NAC group, p = 0.34) with a lower mortality rate (31% vs. 53%, p = 0.36). Side effects of NAC were not found. Conclusion NAC may be beneficial in dengue-associated pediatric ALF. Further well-designed randomized control trials should be carried out.

接受或不接受 N-乙酰半胱氨酸治疗的儿童被诊断为登革热相关急性肝衰竭的临床结果:一项回顾性队列研究

目的 N-乙酰半胱氨酸 (NAC) 已被证明可预防肝损伤并改善微循环血流量和向组织输送氧气。以前的研究已经提出了 NAC 在登革热相关急性肝衰竭 (ALF) 中的益处。然而,大多数研究都是描述性的,缺乏组间比较。我们旨在比较接受和未接受 NAC 治疗的患者的 ALF 解决率和死亡率。方法 对 2002 年 1 月至 2019 年 7 月在泰国一家三级医院诊断为登革热相关 ALF 的年龄 <15 岁儿童进行回顾性队列研究。收集人口统计学和临床​​信息。主要结果是 ALF 分辨率和死亡率。结果共纳入33例患者,其中16例接受NAC治疗(48.5%)。平均年龄为 8 岁。5 年 (SD 3.7),ALF 平均发病时间为发热后 6.3 天 (SD 1.6)。肝性脑病(HE)和器官衰竭的分级在两组之间没有显着差异。在 NAC 组中,13/16 名儿童接受了 100 mg/kg/天的 NAC 处方,直到 INR <2 没有 HE 或 <1.5 有 HE。NAC 在 ALF 诊断后 1.1 天 (SD 0.3) 开始。NAC 组显示出更高的 ALF 解决率(非 NAC 组为 75% 对 53%,p = 0.34),死亡率更低(31% 对 53%,p = 0.36)。未发现 NAC 的副作用。结论 NAC 可能对登革热相关的小儿 ALF 有益。应进行进一步精心设计的随机对照试验。肝性脑病(HE)和器官衰竭的分级在两组之间没有显着差异。在 NAC 组中,13/16 名儿童接受了 100 mg/kg/天的 NAC 处方,直到 INR <2 没有 HE 或 <1.5 有 HE。NAC 在 ALF 诊断后 1.1 天 (SD 0.3) 开始。NAC 组显示出更高的 ALF 解决率(非 NAC 组为 75% 对 53%,p = 0.34),死亡率更低(31% 对 53%,p = 0.36)。未发现 NAC 的副作用。结论 NAC 可能对登革热相关的小儿 ALF 有益。应进行进一步精心设计的随机对照试验。肝性脑病(HE)和器官衰竭的分级在两组之间没有显着差异。在 NAC 组中,13/16 名儿童接受了 100 mg/kg/天的 NAC 处方,直到 INR <2 没有 HE 或 <1.5 有 HE。NAC 在 ALF 诊断后 1.1 天 (SD 0.3) 开始。NAC 组显示出更高的 ALF 解决率(非 NAC 组为 75% 对 53%,p = 0.34),死亡率更低(31% 对 53%,p = 0.36)。未发现 NAC 的副作用。结论 NAC 可能对登革热相关的小儿 ALF 有益。应进行进一步精心设计的随机对照试验。3)ALF诊断后。NAC 组显示出更高的 ALF 解决率(非 NAC 组为 75% 对 53%,p = 0.34),死亡率更低(31% 对 53%,p = 0.36)。未发现 NAC 的副作用。结论 NAC 可能对登革热相关的小儿 ALF 有益。应进行进一步精心设计的随机对照试验。3)ALF诊断后。NAC 组显示出更高的 ALF 解决率(非 NAC 组为 75% 对 53%,p = 0.34),死亡率更低(31% 对 53%,p = 0.36)。未发现 NAC 的副作用。结论 NAC 可能对登革热相关的小儿 ALF 有益。应进行进一步精心设计的随机对照试验。
