RESUMO
BACKGROUND: The Centers for Disease Control and Prevention recommend hospitals develop guidelines for the appropriate use of vancomycin as part of comprehensive antimicrobial stewardship. The objective of this study was to evaluate the effectiveness and safety of a guideline to restrict vancomycin use in the neonatal intensive care unit (NICU). METHODS: A vancomycin use guideline was introduced in 2 tertiary care NICUs with low incidences of methicillin-resistant Staphylococcus aureus infections. We compared all infants >72 hours of age who were evaluated for late-onset infection before and after implementation of this guideline. RESULTS: Vancomycin start rates were reduced from 6.9 to 4.5 per 1000 patient-days (35% reduction; P = 0.01) at Brigham and Women's Hospital, and from 17 to 6.4 per 1000 patient-days (62% reduction; P < 0.0001) at Massachusetts General Hospital. The number of infants exposed to vancomycin decreased from 5.2 to 3.1 per 1000 patient-days (40% reduction; P = 0.008) at Brigham and Women's Hospital, and 10.8 to 5.5 per 1000 patient-days (49% reduction; P = 0.009) at Massachusetts General Hospital. Causes of infection, duration of bacteremia, and incidence of complications or deaths attributable to late-onset infection did not change significantly at either institution. CONCLUSIONS: Implementation of a NICU vancomycin use guideline significantly reduced exposure of newborns to vancomycin without adversely affecting short-term patient safety. Further studies are required to evaluate the long-term effect of vancomycin restriction on NICU patient safety and microbial ecology, particularly among institutions with higher rates of methicillin-resistant Staphylococcus aureus infections.

The first case of an infant with a dual genetic diagnosis of CHARGE and Marfan syndrome is reported here. The patient had multiple congenital anamolies, many of them consistent with CHARGE syndrome and genetic testing identified a heterozygous mutation c.3806_11del6insA in the CHD7 gene. In addition, his father had physical features consistent with Marfan syndrome. Fibrillin-1 (FBN1) mutation screening identified a heterozygous c.3990insC mutation in both father and the patient.
