围生期巨细胞病毒感染5年临床总结

目的 研究围生期巨细胞病毒(CMV)感染的的发病情况、临床特征、治疗及影响更昔洛韦疗效的因素。方法 回顾性分析2008~2012年237例临床诊断为围生期CMV感染的住院患儿的临床资料。结果 5年间围生期CMV感染患儿基本特征及占同期总住院患儿的比例无明显差异。患儿多为2个或2个以上系统受累,CMV肝炎合并CMV肺炎(43.1%)为最常见的临床类型。病原学检测结果提示血CMV-IgM及血/尿CMV-DNA均阳性为3.8%,仅血CMV-IgM阳性为90.3%,仅血/尿CMV-DNA阳性为5.9%。197例患儿接受了更昔洛韦治疗,治愈率为88.3%。母孕史异常(OR=6.191,95% CI:1.597~24.002)和用药前患儿肝脏受累(OR=3.705,95% CI:1.537~8.931)是影响更昔洛韦对围生期CMV感染患儿疗效的独立危险因素。结论 围生期CMV感染近5年的流行病学特征较为稳定。CMV常侵犯多个脏器或系统,以肝肺损害最常见。更昔洛韦治疗围生期CMV感染疗效明显;母孕史异常和用药前患儿肝脏受累会增加围生期CMV患儿对更昔洛韦耐药的风险。     

Cytomegalovirus and ulcerative colitis: Place of antiviral therapy

The link between cytomegalovirus(CMV) infection and inflammatory bowel diseases remains an important subject of debate. CMV infection is frequent in ulcerative colitis(UC) and has been shown to be potentially harmful. CMV reactivation needs to be diagnosed using methods that include in situ detection of viral markers by immunohistochemistry or by nucleic acid amplification techniques. Determination of the density of infection using quantitative tools(numbers of infected cells or copies of the genome) is particularly important. Although CMV reactivation can be considered as an innocent bystander in active flareups of refractory UC, an increasing number of studies suggest a deleterious role of CMV in this situation. The presence of colonic CMV infection is possibly linked to a decreased response to steroids and other immunosuppressive agents. Some treatments, notably steroids and cyclosporine A, have been shown to favor CMV reactivation, which seems not to be the case for therapies using anti-tumor necrosis factor drugs. According to these findings, in flare-ups of refractory UC, it is now recommended to look for the presence of CMV reactivation by using quantitative tools in colonic biopsies and to treat them with ganciclovir in cases of high viral load or severe disease.     

Selective elimination of HIV-1-infected cells by Env-directed, HIV-1-based virus-like particles

We recently showed that both replicating and resting cells cultivated with ganciclovir (GCV) were killed when challenged with vesicular stomatitis virus G glycoprotein pseudotyped HIV-1-based virus-like particles (VLPs) carrying the Nef7 (i.e., an HIV-1 Nef mutant incorporating in virions at high levels)/herpes simplex virus-1 thymidine kinase (HSV-TK) fusion product. On this basis, a novel anti-HIV therapeutic approach based on Nef7/TK VLPs expressing X4 or R5 HIV cell receptor complexes has been attempted. We here report that (CD4-CXCR4) and (CD4-CCR5) Nef7-based VLPs efficiently enter cells infected by X4- or R5-tropic HIV-1 strains, respectively. Importantly, the delivery of the VLP-associated Nef7/TK led to cell death upon GCV treatment. Of interest, VLPs were effective also against non-replicating, HIV-1-infected primary human monocyte-derived macrophages. HIV-targeted VLPs represent a promising candidate for the treatment of persistently HIV-1-infected cells that are part of virus reservoirs resistant to HAART therapies.     

更昔洛韦联合He-Ne激光治疗眼带状疱疹40例疗效分析

目的 观察更昔洛韦联合He-Ne激光治疗眼带状疱疹的临床疗效.方法 将40例眼带状疱疹患者随机分成两组,治疗组20例给予更昔洛韦静脉输入,VitB1、VitB12服,合并角膜炎、虹膜睫状体炎者加用更昔洛韦滴眼液及散瞳药,同时联合He-Ne激光照射三叉神经相应部位;对照组20例单独给予上述药物治疗.观察患者水疱结痂,疼痛消失及眼并发症消失的时间.结果 治疗组水疱结痂及疼痛消失时间、眼并发症消失时间明显短于对照组.结论 联合He-Ne激光疗法治疗眼带状疱疹疗效明显优于单独药物治疗.
