まとめ
結核性義肢関節感染症 (TB-PJIs) はまれで,しばしば培養陰性である. 先進的なシーケンシングにより,膝の置換部感染症でMycobacterium tuberculosisを特定し,困難なケースでは疑いの必要性を強調しました.
科学分野:
- 感染症 感染症は感染症です.
- 整形外科 整形外科
- 微生物学 微生物学とは
背景:
- Mycobacterium tuberculosisは通常,肺疾患を引き起こすが,骨や関節のような肺の外部部部位に影響を与える可能性があります.
- 結核性義肢関節感染症 (TB-PJIs) はまれで,疑いが低いことと,常規の負の培養により,診断が遅れていることが多い.
- 培養陰性義肢膝関節感染症の症例が提示されています.
研究 の 目的:
- マイコバクテリア結核複合義肢関節感染症の珍しい症例を報告します.
- TB-PJIに関連した診断上の課題と治療上の合併症を強調する.
- 培養ネガティブな感染症の診断における高度な分子技術の有用性を強調する.
主な方法:
- 73歳の男性患者が膝関節整形手術を受けた.
- 術後の義肢関節感染症が発生し,最初のルーチンカルチャーが陰性でした.
- 次世代の16S rRNA遺伝子配列が病原体識別に使用されました.
主要な成果:
- 次世代のシーケンシングにより,Mycobacterium tuberculosis complex.を特定しました.
- 患者はRIPE治療を受けたが,拡散性疾患を発症し,薬剤耐性結核の疑いがあった.
- 合併症には膀破裂と多臓器不全があり,死亡に至った.
結論:
- TB-PJIsは,肺の症状なしに現れる可能性があり,特に標準的な治療が失敗した場合は,培養負の関節感染症で考慮する必要があります.
- 多剤耐性の疑いがある場合,TB-PJIの管理が複雑になる可能性があります.
- このケースは,義肢関節の感染症における困難な病原体を特定するための先進的な診断の重要性を強調しています.

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

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.

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
