An outbreak of Candida parapsilosis fungemia among preterm infants
1Department of Neonatology, Affiliated Xingtai People's Hospital of Hebei Medical University, Xingtai, Hebei, China.
Abstract:
In this article, we describe the first outbreak of Candida parapsilosis fungemia in our hospital. We examined a cluster of four nosocomial cases of C. parapsilosis fungemia that occurred in the neonatal intensive care unit (NICU) of the Affiliated Xingtai People's Hospital of Hebei Medical University over a two-week period. We ascertained patient parameters including clinical characteristics, blood and sputum cultures, and drug sensitivity test results. Cultures from eight blood samples obtained from the four infected preterm infants showed identical characteristics and were identified as C. parapsilosis. In order to determine the infection-related factors and to control the spread of the infection among the population, we immediately initiated the emergency plan. All four of the preterm infants recovered from the infection; there were no deaths. Outbreaks of C. parapsilosis, mostly involving preterm infants of very low birth weight or extremely low birth weight, can and do occur in NICUs. Cultures prepared using multiple samples taken from different patients contribute to a more definitive diagnosis. Established measures that control and prevent the infection, as well as effective and comprehensive treatments, can lead to a favorable outcome. That is to say, improving both disinfection and isolation, as well as interrupting the pathway of transmission, is the key to controlling the spread of infection.
Insights
This study details the first Candida parapsilosis fungemia outbreak in a NICU, affecting four preterm infants. Prompt intervention and treatment led to full recovery, highlighting the importance of infection control in neonatal intensive care units.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Neonatal Care
Background:
- Candida parapsilosis fungemia outbreaks pose a significant threat in Neonatal Intensive Care Units (NICUs).
- Preterm infants, especially those with very low or extremely low birth weight, are particularly vulnerable to such infections.
Purpose of the Study:
- To describe the first documented outbreak of Candida parapsilosis fungemia in a hospital setting.
- To identify infection-related factors and implement control measures for a cluster of cases in the NICU.
- To report on the clinical characteristics, diagnosis, and outcomes of affected preterm infants.
Main Methods:
- Retrospective analysis of four nosocomial cases of C. parapsilosis fungemia in preterm infants.
- Examination of patient clinical data, blood and sputum cultures, and drug sensitivity test results.
- Identification of C. parapsilosis through identical culture characteristics from multiple blood samples.
Main Results:
- Four preterm infants in the NICU were diagnosed with C. parapsilosis fungemia over a two-week period.
- All infected infants received prompt emergency intervention and treatment.
- All four infants recovered from the infection, with no reported deaths.
Conclusions:
- NICU outbreaks of C. parapsilosis fungemia, particularly in vulnerable preterm infants, require immediate attention.
- Comprehensive diagnostic approaches, including multiple cultures, are crucial for definitive identification.
- Effective infection control strategies, including disinfection, isolation, and interrupting transmission, are key to managing outbreaks and achieving favorable patient outcomes.
