概括

与健康个体相比,血液透析患者的人类佩吉病毒-1 (HPgV-1) 感染的患病率显著更高. 这凸显了急需加强透析单位的感染控制,以防止病毒传播的迫切需要.

科学领域:

病毒学病毒学
传染性疾病传染性疾病
公共卫生公共卫生

背景情况:

人类佩吉病毒-1 (HPgV-1) 是一种广泛传播的RNA病毒,其致病作用尚不完全理解.
血液透析 (HD) 患者是易受各种感染的脆弱人群,由于免疫状况受损和经常接触医疗保健.

研究的目的:

确定伊朗血液透析患者中HPgV-1的分子流行率和基因型分布.
在这个人群中调查与HPgV-1相关的潜在风险因素和并发症.
探索HPgV-1联合感染的临床影响.

主要方法:

一个病例控制研究,涉及1576名HD患者和1000名健康对照.
使用嵌套PCR和5'-UTR区域的测序进行HPgV-1检测和基因定型的血清样本分析.
统计分析以确定HPgV-1阳性和临床/人口因素之间的关联.

主要成果:

在HD患者中,HPgV-1的患病率明显高于HD患者 (13.6%) 与对照组 (0.6%).
基因型2a是唯一的基因型在阳性HD患者中确定.
在HPgV-1阳性和长时间透析,尿素升高和年龄增加之间发现了显著的关联.
观察到与HCV,HBV和HIV的同时感染,HPgV-1可能会影响HIV同时感染个体的CD4+T细胞计数.

结论:

血液透析是HPgV-1传播的重要风险因素,可能与医院获得的感染有关.
HPgV-1可能具有免疫调节特性,影响同时感染患者的临床结果.
严格的感染控制措施在透析环境中至关重要,以制HPgV-1的传播.

Hemodialysis I: Introduction

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Hepatitis

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
