概括
由Gemella haemolysans引起的败血性手腕关节炎是罕见的. 单一治疗阿莫西西林在免疫功能低下的患者中失败,突出了对这种不寻常的感染有效治疗的组合治疗的需要.
科学领域:
- 传染性疾病 传染性疾病
- 微生物学 微生物学
- 类风湿病学 类风湿病学
背景情况:
- 手腕的败血性关节炎并不常见,通常是由金黄色葡萄球菌引起的.
- 双胞胎血溶菌 (Gemella haemolysans) 是骨关节感染中罕见的病原体,更频繁地与假肢关节感染或脊髓炎有关.
研究的目的:
- 报告一个因Gemella haemolysans引起的本地手腕败血性关节炎病例,该病例发生在免疫功能低下的患者身上.
- 讨论贝塔乳单独治疗的局限性和结合治疗对Gemella haemolysans关节感染的潜在益处.
主要方法:
- 一个45岁的女性患者的病例介绍,她患有并发感染 (HBV-HIV,多发性骨髓瘤),手腕胀和发烧.
- 从突液和血液培养物中鉴定 Gemella 血解菌.
- 治疗过程包括初始的阿莫西西林单一治疗,随后是阿莫西西林和克林达米辛的联合治疗.
主要成果:
- 双胞胎血溶菌被确定为败血性手腕关节炎的致病原体.
- 阿莫西西林单一治疗未能解决感染,持续的症状和炎症标志物证明了这一点.
- 与阿莫西西林和克林达米辛的联合治疗在五周后导致了完全的临床和生物解脱.
结论:
- 单独使用β-乳治疗可能不足以治疗由Gemella haemolysans引起的原生关节感染,特别是在免疫受损的宿主中.
- 导致治疗失败的因素可能包括药物透率差,缺乏手术脱bridement,以及未经验证的药物动力学/药物动力学断点.
- 早期重新评估和迅速启动组合疗法对于管理Gemella haemolysans骨关节感染在脆弱患者中至关重要.

Rheumatic Heart Disease I: Introduction
415
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Genome-wide Association Studies-GWAS
15.2K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
