まとめ
エムポックス治療に使用されるテコビマトは、肝障害を引き起こす可能性があります。この症例報告は、患者における重度の肝毒性を詳述しており、エムポックス治療中の注意深いモニタリングの必要性を強調しています。
科学分野:
- 肝臓学
- 感染症
- 薬理学
背景:
- テコビマトは、2022年から2024年の世界的なアウトブレイク中のエムポックス治療に広く使用されている。
- 初期の報告では、テコビマトの忍容性が高く、毒性が低いことが示唆されていた。
- 最近の研究では、エムポックス病変を減少させるテコビマトの効果は限定的であることが示唆されている。
研究 の 目的:
- エムポックス患者におけるテコビマト関連の重度の肝障害の最初の症例を報告すること。
- 薬物警戒データおよび類似の有害薬物反応の文献をレビューすること。
主な方法:
- エムポックス患者53歳男性の症例報告。
- 肝酵素(AST、ALT、LDH)、血小板数、プロトロンビン時間のモニタリング。
- テコビマト関連肝毒性の薬物警戒データベースレビューおよび文献検索。
主要な成果:
- 患者はテコビマト投与開始後48時間で肝酵素(AST 881U/L、ALT 656U/L)の上昇を認めた。
- 血小板減少症およびプロトロンビン時間延長を含む中等度の肝障害が観察された。
- テコビマト中止後6週間以内に肝機能検査値は正常化した。
結論:
- この症例は、テコビマトの潜在的な肝毒性効果を強調するものである。
- 有効性が不明確であり、肝障害のリスクがあるため、テコビマトの処方には注意が必要である。
- エムポックス治療でテコビマトを受けている患者では、肝毒性の綿密なモニタリングが不可欠である。

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Stages of Infection
65.4K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Defense Mechanism Against Infection
9.8K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Sexually Transmitted Infections

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...

Factors Affecting the Risk of Infection
13.7K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
