Immunodeficiency Diseases

3.7K
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...

Sexually Transmitted Infections

2.0K
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Pulmonary Tuberculosis I

1.7K
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Bacterial Gastroenteritis

88
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...

Encephalitis l: Introduction

15
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Encephalitis ll: Pathophysiology

22
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

まとめ

小児多発性硬化症 (MS) 患者は,健康な子供と比較して,エプスタイン・バーウイルス (EBV) 感染症に対するより高い血清陽性性を示しています. これは,EBVと若年層におけるMSの発症との潜在的な関連を示唆している.

科学分野:

  • ウイルス学 ウイルス学 ウイルス学
  • 神経学 神経学とは
  • 免疫学 免疫学とは

背景:

  • エプスタイン・バーウイルス (EBV) は,多発性硬化症 (MS) の病原化に寄与すると疑われる.
  • 小児性MSにおけるウイルス関連に関する研究は限られている.

研究 の 目的:

  • 健康な対照群と比較して,多発性硬化症の小児におけるEBVおよびその他の一般的なウイルスに対する血清陽性性を調査する.
  • 小児性MSにおける潜在的なウイルス学的要因を探求する.

主な方法:

  • 30人の小児性多発性硬化症患者と143人の対照群 (90人の急診室,53人の健康者) を対象としたケース・コントロール研究.
  • 血清サンプルから,EBV,サイトメガロウイルス,パルボウイルスB19,ヘルペス・シンプレックスウイルス,疹ウイルスに対するIgG抗体を分析した.
  • 出生年に基づいて対照群を一致させた.

主要な成果:

  • 小児性多発性硬化症患者の83%は,遠隔のEBV感染の血清学的証拠があり,対照群の42% (P<.001) でした.
  • 小児性多発性硬化症の患者は,ヘルペス・シンプレックスウイルスに感染する可能性が低かった (P=.003).
  • サイトメガロウイルス,パルボウイルスB19,または水菌ゾステルに対する陽性性の有意な差はありません.
