HLH-2004方案治疗继发性噬血细胞性淋巴组织细胞增多症10例临床分析

本研究旨在探讨HLH-2004方案在继发性噬血细胞性淋巴组织细胞增多症（secondary hemophagocytic lymphohistiocytosis,sHLH）患者中的临床疗效。对我科10例行HLH-2004方案化疗的sHLH患者进行回顾性分析。结果表明,化疗中7例患者有临床反应,3例患者无反应。5例sHLH患者未完成8周初始治疗,其中4例死亡,1例因严重药物副反应改用CHOP方案,治疗4个疗程后获疾病缓解。5例患者完成初始治疗,3例获疾病缓解,2例疾病控制不佳。3例缓解患者中,1例死于疾病复发,另2例维持缓解;2例控制不佳的患者中,1例死亡,另1例出院后获疾病缓解。结论：感染相关的HLH（IAHS）患者予HLH-2004方案化疗联合有效抗感染治疗后缓解率高,而EB病毒相关的HLH（EBV-HLH）或淋巴瘤相关的HLH（LAHS）患者缓解率低、缓解后易复发。

Clinical Analysis of 10 Cases of Secondary Hemophagocytic Lymphohistiocytosis Treated with HLH-2004 Chemotherapy

This study was aimed to investigate the therapeutic effecacy of HLH-2004 chemotherapy in patients with secondary hemophagocytic lymphohistiocytosis （sHLH）. 10 cases of sHLH treated with HLH-2004 regimen at our department were analyzed retrospectively. The results showed that 7 patients had clinical response to HLH-2004 regimen, while other 3 patients had no clinical response. 5 cases did not complete initial therapy of 8 weeks. Out of 5 cases, 4 died in the process of chemotherapy, 1 patient abandoned for serious side effects but finally acquired remission following 4 cycles of CHOP regimen. 5 cases underwent the whole courses of initial therapy. Out of 5 cases, 3 patients acquired remission, and other 2 were not well controlled. Out of the 3 patients who had achieved remission, one died of relapse, and other 2 patients kept remission. Out of the 2 patients who were not well controlled, one patient died, but another patient acquired remission after being discharged. It is concluded that patients with infection-associated hemophagocytic syndrome （IAHS） have high rates of remission after receiving HLH-2004 regimen combining with effective antibiotics. However, patients with HLH secondary to EBV （EBV-HLH） or lymphoma （LAHS） have low rates of remission or are easy to get relapse after remission.
