medRxiv : the preprint server for health sciences
|February 23, 2026
概括
发现COVID-19患者的人类病毒 (HPgV) 联合感染率较低,与一般人口估计值相比较. 然而,HPgV联合感染显示趋势朝着较温和的COVID-19结果,这表明在疾病调节中的潜在作用.
科学领域:
- 病毒学 病毒学
- 传染性疾病 传染性疾病
- 免疫学 免疫学 免疫学
背景情况:
- 人类佩吉病毒 (HPgV) 是一种广泛传播的,监测不足的病毒,具有已知的免疫调节作用.
- 与美国普通人口 (1-2%) 相比,HPgV的患病率在同时感染的人群中更高,例如艾滋病毒感染者 (15-40%),与美国普通人口 (1-2%) 相比.
- HPgV联合感染对SARS-CoV-2感染严重性的潜在影响仍未被探索.
研究的目的:
- 在感染SARS-CoV-2的患者中调查人类病毒 (HPgV) 的流行率.
- 评估HPgV联合感染与COVID-19疾病严重程度之间的关联.
- 探索病毒共同感染在调节COVID-19结果中的作用.
主要方法:
- 分析了四个队列:SARS-CoV-2阳性患者,SARS-CoV-2阴性ICU患者,HIV阳性个体 (HPgV阳性对照) 和未感染的对照.
- 在634名COVID-19患者中对HPgV进行系统查.
- 在不同患者群体中比较HPgV患病率,以验证试验性能和分层队列.
主要成果:
- 在COVID-19患者中HPgV患病率为2.1%,与一般人口估计相一致.
- 在HIV队列中,HPgV的患病率明显高 (34%),证实了试验有效性.
- 尽管存在风险因素,但HPgV阳性COVID-19病例呈现了较轻症的趋势. 在医疗保健工作者 (9.6%) 中发现患病率较高.
结论:
- HPgV是一种常见的,未被监测的病毒共感染,可能会影响宿主对SARS-CoV-2的反应.
- 研究结果表明,HPgV联合感染可能与COVID-19的严重程度降低有关,需要进一步调查.
- 该研究强调了在SARS-CoV-2感染的背景下考虑免疫调节性病毒共同感染的重要性.

Viral Recombination
25.4K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Pharmacokinetics: Drug–Food and Drug–Viral Interactions
306
A drug interaction occurs when the concurrent use of another drug, food, or an external substance alters the pharmacological activity of a drug. This interaction can modify the action of the original drug, affecting its effectiveness and safety.Drug–food interactions are significant as they impact drug absorption, metabolism, and excretion. For example, grapefruit juice is a well-known disruptor of drug metabolism. It inhibits the cytochrome P450 3A4 enzyme, crucial for the metabolism of...

COPD: Pathogenesis and Clinical Features
1.9K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Single Nucleotide Polymorphisms-SNPs
18.7K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Subviral Agents
642
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
