摘要
目的观察波生坦在儿童先天性心脏病(CHD)相关肺动脉高压(PAH)患儿中应用的疗效及安全性,评价波生坦治疗儿童CHD—PAH的临床效果。方法人选2008年1月至2011年5月首都医科大学附属北京安贞医院小儿心脏科入院≤18岁CHD—PAH患儿23例,给予波生坦口服治疗,进行开放性、观察性研究。随访评估服药前后6min步行试验距离(6MWTD)、经皮血氧饱和度(SpO2)、纽约心脏病学会心功能分级(NYHA—FC)、心导管检查血流动力学参数(平均肺动脉压、肺小动脉阻力指数、肺体循环流量比、肺体循环阻力比)及肝功能变化。结果入选儿童患儿23例,平均年龄为(9.1±3.6)岁(2.1~14.7岁)。口服波生坦治疗平均时间(13.3±7.5)个月(6~31个月)。治疗后,11例患儿(年龄7岁以上)的6MWTD从(458±16)m增加至(496±49)m(P=0.035)。23例患儿的SpO2(89±6)%提高到(91±5)%(P=0.009)。此外,所有患儿的NYHA心功能分级有不同程度改善或保持稳定。12例服药后再次接受心导管检查的患儿,肺、体循环比(Qp/Qs)由服药前平均(0.97±0.38)增至(1.16±0.39)(P=0.076),平均肺动脉压(mPAP)由(76±6)mmHg(1mmHg=0.133kPa)增至(78.4-12)mmHg(P=0.649),肺小动脉阻力指数(PVRi)由平均(20.78±8.84)Woodsunits/m2降至(18.13±7.71)Woodsunits/m2(P=0.165),肺、体循环阻力比(Rp/Rs)由(1.03±0.38)降至(0.83±0.29)(P=0.06),以上指标均有不同程度改善,但差异无统计学意义。所有患儿均对波生坦良好耐受,仅1例10岁男性患儿有一过性鲜血便。结论服用波生坦可明显改善CHD—PAH患儿的6MWT、SpO2、NYHA—FC,降低PVR及Rp/Rs。波生坦在不符合手术适应证的儿童CHD—PAH患儿中的应用是安全、有效的。
Objective To describe the safety and effect of the non-selective endothelin receptor antagonist bosentan used in children with pulmonary arterial hypertension (PAH) associated with unrepaired congenital heart disease (CHD). Methods In this monocentre,open-label,uncontrolled and observational study, pediatric patients (age ≤ 18 years)with PAH associated with CHD between January 2008 and May 2011 were selected. 6-minute walk distance(6MWTD), transcutaneous oxygen saturation( Sp02% ), New York Heart Association functional class (NY- HA-FC) ,hemodynamic parameters and liver function were assessed at baseline,3 months, 6 months, 1 year and at latest follow-up. Results Totally 23 patients were treated with bosentan. The mean age was (9. 1 ± 3.6) years (range 2. 1-14. 7 ). The mean treatment time was (13.3 ± 7. 5 ) months (range 6-31 months). Bosentan improved 6MWTD(n = 11) from (458 ±16)m to (496 ±49)m (P =0.035) ,SPO2% (n =23) from 89% +6% to 91% ± 5% (P = 0. 009). All patients received cardiac catherization at baseline, of them 12 patients received that again after 6-month treatment. Bosentan improved Qp/Qs from 0. 97 ± 0. 38 to 1. 16 ± 0. 39 ( P = 0. 076 ) and decreased PVRi from ( 20.78 ± 8.84) Woods units/m2 to ( 18.13 ± 7.71 ) Woods units/m2 ( P = 0. 165 ), Rp/Rs from 1.03 ± 0. 38 to 0. 83± 0. 29 ( P = 0. 06 ), No patient died. Conclusions Bosentan can significantly improve 6MWT, SpO2 % and NYHA function class, decrease PVRI and Rp/Rs in children with PAH associated with CHD. It is safe and effective in children with PAH associated with CHD.
