概括
细胞巨乳病毒 (CMV) 感染仍然是一个高风险的心脏移植接受者与捐赠者阳性,接受者阴性 (D + / R-) 不匹配,即使在当前的抗病毒预防. 需要量身定制的方案来改善这个脆弱的患者群体的治疗结果.
科学领域:
- 移植免疫学 移植免疫学
- 传染性疾病 传染性疾病
- 心脏病学 心脏病学
背景情况:
- 细胞巨乳病毒 (CMV) 感染与心脏移植 (HT) 接受者的较差结果有关.
- 血清CMV不匹配 (捐赠者阳性,接受者阴性 - D+/R-) 显著增加感染风险.
- 目前的指导方针建议对D+/R-HT患者进行3-6个月的抗病毒预防.
研究的目的:
- 分析D+/R-心脏移植接受者中CMV感染的发生率和模式.
- 确定在高风险人群中管理CMV的潜在改进领域.
- 评估当前预防策略的有效性.
主要方法:
- 在10年内对35名成年HT接受者进行了回顾性分析,CMV D+/R-不匹配.
- 患者被跟踪到2023年10月.

139
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
