Blood:丙酮酸激酶缺陷病的国际性临床资料统计

2018-03-17 MedSci MedSci原创

丙酮酸激酶(PK)缺陷,是一种最常见的可导致遗传性非球形细胞性溶血性贫血的糖酵解缺陷,为收集该缺陷患者的回顾性和前瞻性临床资料,国际上建立一多中心的国际性注册记录。回顾性收集了254位在分子水平确诊PK缺陷患者的病史、实验室和放射学资料。PK缺陷常见围产期并发症,包括需要输血的贫血、高胆红素血症、水肿和早产。几乎所有的新生儿(93%)均需要进行蓝光治疗(治疗黄疸),而且46%的新生儿接受换血治疗。

丙酮酸激酶(PK)缺陷,是一种最常见的可导致遗传性非球形细胞性溶血性贫血的糖酵解缺陷,为收集该缺陷患者的回顾性和前瞻性临床资料,国际上建立一多中心的国际性注册记录。回顾性收集了254位在分子水平确诊PK缺陷患者的病史、实验室和放射学资料。

PK缺陷常见围产期并发症,包括需要输血的贫血、高胆红素血症、水肿和早产。几乎所有的新生儿(93%)均需要进行蓝光治疗(治疗黄疸),而且46%的新生儿接受换血治疗。5岁及以下的幼儿,经常进行输血,直至行脾切除术。254位患者中有150位(59%)采取脾切除术治疗;脾切除术可提高血红蛋白水平(提高中位值1.6g/dl),并降低90%的患者的输血负担。

对脾切除术的反应的预测因子:脾切术前血红蛋白更高(p=0.007)、间接胆红素更低(p=0.005)和PKLR错义突变(0.0017)。11%的患者脾切术后报道有血栓形成。最常见的并发症有铁过负荷(48%)和胆结石(45%);不常见的并发症有再生障碍危象、骨质疏松和骨脆弱、髓外造血、脾切术后脓毒症、肺动脉高压和腿部溃疡等。

87位(34%)患者行脾切除术和胆囊切除术。行脾切而未同时切除胆囊的患者中,有48%随后再次行胆囊切除术。

尽管现已发现并发症风险会随着贫血的严重程度和基因型表现关系而增加,但在所有PK缺陷患者中并发症还是很常见。因此对于有明显先天性溶血性贫血的患者,应该考虑予以行PK缺陷的诊断检验,并密切监测其铁负荷、胆结石和其他并发症。
