Abstract
Virus-specific T cells have proven highly effective for the treatment of severe and drug-refractory infections after hematopoietic stem cell transplant (HSCT). However, the efficacy of these cells is hindered by the use of glucocorticoids, often given to patients for the management of complications such as graft-versus-host disease. To address this limitation, we have developed a novel strategy for the rapid generation of good manufacturing practice (GMP)-grade glucocorticoid-resistant multivirus-specific T cells (VSTs) using clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein 9 (Cas9) gene-editing technology. We have shown that deleting the nuclear receptor subfamily 3 group C member 1 (NR3C1; the gene encoding for the glucocorticoid receptor) renders VSTs resistant to the lymphocytotoxic effect of glucocorticoids. NR3C1-knockout (KO) VSTs kill their targets and proliferate successfully in the presence of high doses of dexamethasone both in vitro and in vivo. Moreover, we developed a protocol for the rapid generation of GMP-grade NR3C1 KO VSTs with high on-target activity and minimal off-target editing. These genetically engineered VSTs promise to be a novel approach for the treatment of patients with life-threatening viral infections post-HSCT on glucocorticoid therapy.

Abstract
OBJECTIVE To assess the rate of, and risk factors for, human cytomegalovirus viremia (HCMV) in donor+/recipient+ (HCMV serostatus matched) hematopoietic stem-cell transplantation (HSCT) recipients. METHODS HCMV DNA from 144 donor+/recipient+ HSCT recipients was examined by quantitative polymerase chain reaction (qPCR). RESULTS The cumulative incidence of HCMV viremia was 69.4% (100/144) during the 48 weeks after HSCT. In a multivariate analysis, acute graft-versus-host disease (aGVHD) was discovered to be a risk factor for the occurrence of HCMV viremia (P = .006). The cumulative incidence of HCMV viremia and increasing DNA loads were significantly associated with aGVHD occurrence (P = .001 for each). The occurrence of late-term HCMV viremia was associated with aGVHD (P = .001) and a higher DNA load during the first 12 weeks after HSCT (P = .04). CONCLUSIONS aGVHD is a risk factor for HCMV viremia. Recipients with aGVHD who have a high HCMV DNA load should be strictly monitored to prevent HCMV activation.

Abstract
目的 采用多重PCR方法分析造血干细胞移植(HSCT)患者多种疱疹病毒的感染状况,并探讨HSCT患者多种疱疹病毒感染与临床特征的相关性及其对移植并发症和预后的影响。 方法 以苏州大学附属第一医院血液科2017年2月至2017年8月行HSCT的90例患者为研究对象,收集预处理至移植后90 d内不同时间点的外周血标本共734份,Lab-Aid824核酸提取Mini试剂抽提DNA,应用多重PCR方法同时扩增8种人类疱疹病毒,分析多种疱疹病毒感染发生率及其与临床特征的相关性及对移植后并发症和预后的影响。 结果 至随访终点,中位随访时间为192(35~308)d。移植前疱疹病毒感染发生率为35.6%(32/90),其中1种疱疹病毒感染发生率为12.2%(11/90),多种病毒感染的发生率为23.3%(21/90)。移植后疱疹病毒感染发生率为77.8%(70/90),其中1种疱疹病毒感染发生率为20.0%(18/90),多种疱疹病毒感染的发生率为57.8%(52/90)。在多种疱疹病毒感染的患者中,2种病毒感染30例(57.7%),3种疱疹病毒感染18例(34.6%),不同时间点样本检测的4种疱疹病毒感染4例(7.7%)。移植后多种疱疹病毒感染中,HHV-6和HHV-7感染存在相关性(OR=13.880,Q=0.026),EBV和HHV-7感染也存在相关性(OR=0.093,Q=0.044)。25例患者移植后出现疱疹病毒感染相关临床表现,主要为出血性膀胱炎、间质性肺炎、肠炎、病毒性脑炎和不明原因发热。移植前HHV-1感染与年龄、HHV-2感染与发病时间、CMV感染与原发病为淋巴瘤具有一定的相关性。移植后EBV感染与HLA不全相合、供受者ABO血型不一致及Ⅱ~Ⅳ度急性GVHD呈正相关;多种疱疹病毒感染与HLA不全相合、非血缘供者及Ⅱ~Ⅳ度急性GVHD呈正相关。 结论 HSCT前后存在多种疱疹病毒感染,HLA不全相合、非血缘供者和Ⅱ~Ⅳ度急性GVHD与移植后多种疱疹病毒感染存在一定的相关性。

Abstract
Dermatology consultation can improve diagnostic accuracy in the hospitalized patient with cutaneous disease. Dermatology consultation can streamline and improve treatment plans, and potentially lead to cost savings. Dermatology consultants can be a valuable resource for education for trainees, patients, and families. Inpatient consultative dermatology spans a breadth of conditions, including inflammatory dermatoses,infectious processes, adverse medication reactions, and neoplastic disorders, many of which can be diagnosed based on dermatologic examination alone, but when necessary, bedside skin biopsies can contribute important diagnostic information.
