Rise of Hypervirulent Resistant K pneumoniae in EU

Core Concepts

Hypervirulent Klebsiella pneumoniae (hvKp) ST23 poses a significant threat due to its resistance to last-line antibiotics and high invasiveness.

Abstract

The European Centre for Disease Prevention and Control (ECDC) warns of the high risk of further spread of hypervirulent Klebsiella pneumoniae (hvKp) sequence type (ST) 23 between healthcare facilities.
The number of EU and EEA countries reporting hvKp ST23 has more than doubled, with 10 countries now affected.
Cases reported to the ECDC have increased significantly, raising concerns due to the severity of hvKp infections and their resistance to last-line antibiotics.
HvKp infections can be life-threatening, affecting young and healthy individuals, and are associated with high morbidity and mortality.
HvKp strains are circulating among healthy individuals, causing a different spectrum of disease compared to classic K pneumoniae.
The spread of carbapenem-resistant hvKp in healthcare settings is expected to increase morbidity and mortality.
Increased clinical and public health awareness, along with enhanced laboratory capacity, are crucial to prevent further dissemination of hvKp.

Stats

The number of European Union (EU) and European Economic Area (EEA) countries reporting hvKp ST23 had more than doubled, from four to 10, since the previous rapid risk assessment in 2021.
The number of total cases reported to the ECDC by these countries has increased from 12 to 143.
HvKp strains were primarily found in Asia, were mainly community-acquired, and were only rarely resistant to antibiotics.
HvKp ST23 had increasingly acquired a variety of genes associated with resistance to carbapenems.

Quotes

"The increases in cases of carbapenem-resistant hypervirulent Klebsiella pneumoniae (hvKp) reported to ECDC by EU/EEA countries is a cause for concern because of the severity of hvKp infections combined with their resistance to last-line antibiotics, which makes the infections difficult to treat." - Dominique Monnet, ECDC

Deeper Inquiries

How can healthcare facilities enhance infection prevention and control measures to combat the spread of hvKp?

Healthcare facilities can enhance infection prevention and control measures by implementing strict protocols such as proper hand hygiene, isolation precautions for infected patients, and environmental cleaning. Regular surveillance for hvKp, especially in high-risk areas like intensive care units, is crucial. Training healthcare staff on recognizing symptoms, early diagnosis, and appropriate treatment of hvKp infections is essential. Additionally, promoting antimicrobial stewardship to prevent unnecessary antibiotic use can help reduce the development of resistance.

What are the potential implications of underdetecting hvKp isolates and infections in healthcare settings?

Underdetecting hvKp isolates and infections in healthcare settings can have severe consequences. It can lead to delayed or inappropriate treatment, resulting in increased morbidity and mortality among patients. Failure to detect hvKp infections can also contribute to the further spread of the bacteria within healthcare facilities, putting vulnerable patient populations at risk. Additionally, underdetection hinders the understanding of the true prevalence and transmission dynamics of hvKp, impeding effective control measures.

How can global collaboration help address the rising threat of hypervirulent resistant bacteria beyond regional efforts?

Global collaboration is essential in addressing the rising threat of hypervirulent resistant bacteria. By sharing information, best practices, and resources, countries can collectively combat the spread of hvKp and other similar pathogens. Collaborative efforts can facilitate the development of standardized surveillance systems, diagnostic tools, and treatment guidelines. International cooperation can also support research initiatives to better understand the epidemiology and mechanisms of resistance of hypervirulent bacteria, leading to more effective prevention and control strategies on a global scale.
