概括

与单一治疗相比,组合疗法显著减少了长期或复发性COVID-19的免疫功能低下 (IC) 患者的住院治疗和病毒泄漏时间.

科学领域:

免疫学免疫学免疫学
传染性疾病传染性疾病
病毒学病毒学

背景情况:

在免疫功能低下 (IC) 患者中,B细胞枯竭会影响免疫反应.
长期或复发的COVID-19在IC人群中构成了重大挑战.
了解这种队列中的治疗疗效对于临床管理至关重要.

研究的目的:

描述一组B细胞枯竭的IC患者的队列,这些患者患有持续的COVID-19.
为了评估单疗法与IC患者SARS-CoV-2感染的组合治疗的有效性.
确定最佳的治疗策略,以管理长期或复发的COVID-19在免疫功能低下的个体.

主要方法:

多中心观测回顾性研究.
招募了88名患有长期或复发性SARS-CoV-2感染的免疫功能低下患者 (2020年11月 - 2023年1月).
基于单疗法或联合抗SARS-CoV-2治疗的分层患者.

主要成果:

组合疗法组显示,住院时间缩短,时间缩短到负的SARS-CoV-2鼻口腔抽样 (NPS).
多变量分析证实,结合疗法显著减少了NPS负面影响的日数.
研究群体表现出B细胞枯竭 (中位数为2细胞/mm3).

结论:

结合多目标疗法 (抗病毒或抗病毒加抗体) 对于持续COVID-19的IC患者至关重要.
这些策略可能有助于避免持续的病毒泄露和严重的SARS-CoV-2感染.
探索新的治疗方法对于这个脆弱的患者群体至关重要.

Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Tumor Immunotherapy

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Pulmonary Tuberculosis V

Pulmonary Tuberculosis V

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...
