概括

在接受alo-HCT的儿童中,莱特莫维尔预防不影响免疫恢复,但显著减少了细胞巨乳病毒 (CMV) 事件. 这种方法重塑了病毒学格局,在移植后增加了腺病毒 (ADV) 和潜在的爱斯坦-巴尔病毒 (EBV).

科学领域:

血液学血液学血液学
免疫学免疫学免疫学
病毒学病毒学

背景情况:

莱特莫维尔预防已在成年人中建立,以减少血造细胞干细胞移植 (allo-HCT) 后的CMV并发症.
关于莱特莫维尔对免疫恢复和病毒结果的影响的儿科数据有限.
随着莱特莫维尔预防,T细胞的恢复可能会延迟.

研究的目的:

为了比较免疫复合 (CD3 +,CD4 +,CD8 +,CD19 +,NK细胞) 在allo-HCT后的60天和100天.
为了比较病毒结局 (CMV,EBV,ADV,HHV-6,parvovirus B19,HSV,VZV) 在合并HCT后180天内.
评估儿科艾洛-HCT接受者的莱特莫维尔预防与预防性治疗.

主要方法:

追溯性,多中心研究,利用倾向性得分匹配.
81名接受莱特莫维尔预防治疗 (LET) 的儿科患者与81名接受预防治疗 (PET) 的患者进行了比较.
免疫细胞计数的流细胞计;移植后最多180天评估病毒学结果.

主要成果:

在关键时间点在LET和PET队伍之间观察到可比的免疫恢复.
LET显著降低了整体病毒事件 (45/115比70/115) 和CMV发病率 (11.1%比42%).
增加腺病毒 (ADV) 患病率 (8 vs 0) 和晚期病毒性疾病发病趋势 (中位数为58 vs 30天) 在LET组中发现;发生了2例EBV-PTLD病例.

结论:

莱特莫维尔的预防作用不会阻碍儿科allo-HCT接受者的淋巴细胞复制.
莱特莫维尔有效地减少细胞巨乳病毒 (CMV) 负担和移植后的病毒事件.
莱特莫维尔改变了移植后的病毒学特征,增加了ADV,并为EBV相关并发症提供了潜在的信号.

Retrovirus Life Cycles

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Immune Response Against Viral Pathogens

Immune Response Against Viral Pathogens

The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Retroviruses

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Viruses with RNA Genomes

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Immunodeficiency Diseases

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...
