A global point prevalence survey of antimicrobial use in neonatal intensive care units: The no-more-antibiotics and resistance (NO-MAS-R) study.

BACKGROUND: Global assessment of antimicrobial agents prescribed to infants in the neonatal intensive care unit (NICU) may inform antimicrobial stewardship efforts. METHODS: We conducted a one-day global point prevalence study of all antimicrobials provided to NICU infants. Demographic, clinical, and microbiologic data were obtained including NICU level, census, birth weight, gestational/chronologic age, diagnoses, antimicrobial therapy (reason for use; length of therapy), antimicrobial stewardship program (ASP), and 30-day in-hospital mortality. FINDINGS: On July 1, 2019, 26% of infants (580/2,265; range, 0-100%; median gestational age, 33 weeks; median birth weight, 1800 g) in 84 NICUs (51, high-income; 33, low-to-middle income) from 29 countries (14, high-income; 15, low-to-middle income) in five continents received ≥1 antimicrobial agent (92%, antibacterial; 19%, antifungal; 4%, antiviral). The most common reasons for antibiotic therapy were "rule-out" sepsis (32%) and "culture-negative" sepsis (16%) with ampicillin (40%), gentamicin (35%), amikacin (19%), vancomycin (15%), and meropenem (9%) used most frequently. For definitive treatment of presumed/confirmed infection, vancomycin (26%), amikacin (20%), and meropenem (16%) were the most prescribed agents. Length of therapy for culture-positive and "culture-negative" infections was 12 days (median; IQR, 8-14) and 7 days (median; IQR, 5-10), respectively. Mortality was 6% (42%, infection-related). An NICU ASP was associated with lower rate of antibiotic utilization (p = 0·02). INTERPRETATION: Global NICU antibiotic use was frequent and prolonged regardless of culture results. NICU-specific ASPs were associated with lower antibiotic utilization rates, suggesting the need for their implementation worldwide.

Choque séptico fulminante neonatal por Clostridium perfringens / Neonatal fulminant septic shock by Clostridium perfringens

Resumen Clostridium spp. es un bacilo grampositivos, anaerobio, formador de esporas y ampliamente distribuido en el ambiente. Las infecciones por Clostridium perfringens en neonatos son en extremo raras. La sepsis grave por anaerobios, incluyendo el choque séptico, es un evento clínico inusual en este grupo de pacientes. Se reportan dos casos de bacteriemia por C. perfringens asociados a choque séptico fulminante en recién nacidos con enterocolitis necrosante grave.

Abstract Clostridium species are anaerobic, spore, forming gram-positive bacteria that are widely spread in the environment. Clostridium perfringens infections in neonates are extremely rare. Severe anaerobic sepsis, including septic shock, is an unusual clinical event in this group of patients. We highlight two cases of C. perfringens bacteremia associated with fulminant septic shock in neonates with severe necrotizing enterocolitis.

Infección del torrente circulatorio en una unidad de neonatología de Medellín-Colombia, 2008-2009 / Bloodstream infection in a neonatology unit of Medellín-Colombia, 2008-2009

Bloodstream infection (BSI) is one of the main causes of sepsis and death in newborns. The relative importance of nosocomial and non-nosocomial agents in developing countries is not clear. We conducted a prospective study of newborns hospitalized with a first episode of BSI in order to classify it as early, late or nosocomial, describe the clinical and microbiological charateristics, and explore risk factors between hospital-acquired vs commu-nity-acquiered BSI (HA-BSI vs CA-BSI). Twenty-seven newborns with a first episode of BSI were identified. Streptococcus agalactiae and coagulase negative Staphylococcus were the main agents in CA-BSI and HA-BSI, respectively. The only significant intrinsic risk factor between HA-BSI and CA-BSI was gestational age. The frequent finding of S. agalactiae warrants routine screening and prophylaxis in pregnant women. The risk factors for HA-BSI were mostly extrinsic, and thus, susceptible of being modified.

La infección del torrente circulatorio (ITC) es una de las principales causas de sepsis y muerte neonatal. Su etiología en países en vía de desarrollo, entre agentes no nosocomiales vs nosocomiales no está suficientemente esclarecida. Estudio prospectivo que incluyó neonatos hospitalizados que presentaron un primer hemocultivo positivo, con el propósito de describir características clínicas, microbiológicas, clasificar la ITC en temprana, tardía y nosocomial, y explorar factores de riesgo entre ITC adquirida en la comunidad vs ITC adquirida en el hospital (ITC-AC vs ITC-AH). Se identificaron 27 neonatos con un primer episodio de ITC. Streptococcus agalactiae y Staphylococcus coagulasa negativa fueron los principales agentes en ITC-AC e ITC-AH, respectivamente. El factor de riesgo intrínseco que mostró una diferencia significativa entre ITC-AC vs. ITC-AH fue la edad gestacional. La presencia de S. agalactiae permite plantear el tamizaje y profilaxis a la gestante. Los factores de riesgo para ITC-AH fueron en su mayoría extrínsecos, es decir, susceptibles de ser modificados.
