まとめ

イソニアジドによる予防療法の効果は,35歳以上の患者を含むほとんどの患者にとってリスクを上回ります. 現在のガイドラインは,この結核予防のために高齢で低リスクの個人を含めるように改訂されるべきです.

科学分野:

公衆衛生は公衆衛生である.
感染症疫学感染症疫学
臨床的決定分析臨床的決定分析

背景:

現在のイソニアジド化学予防ガイドラインは,35歳以上の個人に使用することを推奨していません.
この年齢に基づく値は,イソニアジド誘発性肝炎のリスクが高いと認識され,アクティブ結核の予防の利点に優れていることに基づいています.

研究の目的:

異なった年齢層におけるイソニアジドの予防療法によるリスクと利益を評価する.
結核素反応が陽性である低リスクの個体において,イソニアジドの使用のための証拠に基づく年齢上限を決定する.

主な方法:

イソニアジド治療と無治療を比較した決定分析.
結果指標には,平均寿命,罹患可能性 (肝炎,アクティブ結核),死亡率などが含まれていた.

主要な成果:

イソニアジドの利点は,平均寿命とすべての年齢 (10〜80歳) における致死性疾患の可能性に対するリスクを上回り,高齢者の場合の利点はより小さくなります.
リスクが利益よりも優れているという値が特定されたのは,病気の確率は,特に50歳から65歳までの年齢層においてのみでした.

結論:

イソニアジドの予防療法に対する現在の年齢制限は,決定分析によって完全に支持されていません.
推奨事項は,イソニアジド化学予防のために35歳以上の低リスクの結核リエクターを含むように更新されるべきである.

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Pulmonary Tuberculosis I

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.
Mode of...

Pulmonary Tuberculosis II

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...

Pulmonary Tuberculosis III

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:

Pulmonary Tuberculosis IV

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...
