[MRSA sepsis of premature infants]
1Second Department of Pediatrics, Dokkyo University School of Medicine.
Abstract:
During the 12 year period from 1978 to 1990, 112 mature newborn and premature infants were diagnosed as sepsis in our nursery. The first case of MRSA sepsis was found in 1985. Since then, cases abruptly increased in number and 31 cases were found in total. Seven cases died and 24 were cured. Antibiotics such as AMK, MINO, IPM were effective. As the sensitivity of these drugs has been gradually dropping, we believe that VCM will be selected as the first choice. Early diagnosis and therapy are most important. Daily measurement of low level CRP (0.1 to 1.0 mg/dl) is useful and careful management is necessary in the course of significant PDA.
Insights
Neonatal sepsis cases, including Methicillin-resistant Staphylococcus aureus (MRSA), increased significantly from 1978-1990. Early diagnosis and C-reactive protein (CRP) monitoring are crucial for managing sepsis in infants with patent ductus arteriosus (PDA).
Area of Science:
- Neonatal Medicine
- Infectious Diseases
- Pediatrics
Context:
- A nursery experienced 112 cases of neonatal sepsis between 1978 and 1990.
- Methicillin-resistant Staphylococcus aureus (MRSA) sepsis emerged in 1985, leading to a sharp increase in cases.
- Thirty-one total cases of MRSA sepsis were identified, with a mortality rate of 22.6% (7 deaths).
Purpose:
- To analyze the incidence and outcomes of neonatal sepsis, particularly MRSA sepsis, in a nursery setting.
- To evaluate the effectiveness of various antibiotics and recommend treatment strategies.
- To highlight the importance of early diagnosis and management, especially in infants with significant patent ductus arteriosus (PDA).
Summary:
- A 12-year study (1978-1990) documented 112 neonatal sepsis cases, with MRSA sepsis rising notably after 1985.
- Effective antibiotics included AMK, MINO, and IPM, but decreasing sensitivity suggests Vancomycin (VCM) as a potential first-choice treatment.
- Early diagnosis, daily low-level C-reactive protein (CRP) measurement (0.1-1.0 mg/dL), and careful management of PDA are critical.
Impact:
- Identified a significant increase in MRSA neonatal sepsis, necessitating updated treatment protocols.
- Emphasized the importance of antibiotic sensitivity monitoring and strategic drug selection (e.g., VCM).
- Stressed the critical role of early detection through CRP monitoring and vigilant care for infants with PDA in reducing sepsis-related mortality.
