RESUMO
We conducted a nested case-control study within a cohort with the aim of studying the association between illicit drug use and congenital syphilis (CS). Cases were diagnosed based on treponemal and non-treponemal tests conducted both in the mother and the newborn (NB). Multivariate analysis with logistic regression was performed. A total of 6171 births with a mean gestational age of 37.8 weeks were recorded and 62 CS events were diagnosed (incidence 10.5 events/1000 NB). Associated maternal factors were illicit drug use (OR 14.08, 95% CI 1.19-166.6), <5 prenatal visits (OR 2.9, 95% CI 1.12-7.53), more than two sexual partners (OR 3.76, 95% CI 1.62-8.71) and professional education level (OR 0.06, 95% CI 0.005-0.85). Among the mothers of the cases presented, the prevalence of illicit drug use was 22.6% and the most frequent drugs were methamphetamines and cannabis.

BACKGROUND: Infections caused by extended-spectrum beta-lactamases enterobacteria (ESBL-EP) have implications for neonatal morbidity and mortality. AIM: To describe the prevalence of ESBL-EP in neonatal sepsis and associated factors. METHODS: A prospective cohort study was conducted from August 2016 to August 2017; newborn babies (NB) hospitalized in the Hospital Civil de Guadalajara "Dr. Juan I. Menchaca" were included. The ESBL-EP were investigated by double-disk synergy test and its association with clinical and demographic characteristics of the NB. RESULTS: A total of 1,501 hospitalized NB were studied, with an average gestational age of 36.3 weeks. They were diagnosed 196 neonatal sepsis events, the most frequent etiologies were enterobacteria (45.5%). Resistance to ampicilin was found in 88.8% and to broad spectrum cephalosporins in more than 42% of the strains; 22.9% of them were ESBL phenotype. Apgar ≤ 7 at five minutes of life (OR 4.6; 95% CI 1.47-14.6) and gestational age < 37 weeks (OR 5.4; 95% CI 1.04-27.) increase the risk. CONCLUSION: In enterobacteria that cause neonatal sepsis, 22.9% were EP-ESBL; infection was more likely in patients with Apgar ≤ 7 at five minutes of age and in preterm infants.

INTRODUCTION: Neonatal sepsis is one of the main causes of death among newborn infants. Empirical antimicrobial treatment is based on epidemiological information and antimicrobial susceptibility tests. The objective of this study was to describe etiologic agents and their antimicrobial susceptibility among newborn infants with early-onset neonatal sepsis (EONS) or late-onset neonatal sepsis (LONS) at a Neonatal Intensive Care Unit. METHODS: Cross-sectional study conducted at a tertiary referral hospital in Western Mexico. Determination of antimicrobial resistance of microorganisms isolated in blood or cerebrospinal fluid of patients with EONS or nosocomial LONS. RESULTS: Yeasts and bacteria were isolated from 235 cultures corresponding to 67 events of EONS and 166 events of LONS. Of all isolates, the most common bacteria were Enterobacteriaceae (51.5%), followed by Streptococcus spp. in EONS, and by Staphylococcus spp. in LONS. Of all nosocomial Enterobacteriaceae, 40% were extended spectrum beta-lactamase producing bacteria. Among Staphylococcus species, resistance to oxacillin was recorded in 65.5%. Among Enterobacteriaceae (n: 121), resistance to amikacin, piperacillin-tazobactam, and meropenem was below 3%. Non-fermenting bacteria did not show resistance to amikacin, ciprofloxacin or cefepime; however, the number of isolates was scarce. CONCLUSIONS: The most commonly identified bacteria in EONS were Enterobacteriaceae (67.6%) and Streptococcus spp. (17.6%), and Enterobacteriaceae (44.9%) and Staphylococcus spp. (34.7%) in LONS. Forty percent ofnosocomial Enterobacteriaceae were extended spectrum beta-lactamase producing bacteria, and 65.5% of Staphylococcus spp. showed resistance to oxacillin.

Resumen Introducción: Las infecciones causadas por enterobacterias productoras de β-talactamasas de espectro extendido (EP-BLEE) tienen implicaciones sobre la morbilidad y mortalidad neonatal. Objetivo: Describir la prevalencia de EP-BLEE en sepsis neonatal y los factores asociados. Métodos: Estudio de cohorte prospectivo, desde agosto del 2016 a agosto del 2017. Se incluyeron recién nacidos (RNs) ingresados en el Hospital Civil de Guadalajara "Dr. Juan I. Menchaca". Mediante prueba de difusión de doble disco se indagó la presencia de EP-BLEE y su asociación con características clínicas y demográficas de los RNs. Resultados: Se estudiaron 1.501 RNs hospitalizados, con edad gestacional promedio de 36,3 semanas. Se diagnosticaron 196 eventos de sepsis neonatal, la etiología más frecuente fueron enterobacterias (45,5%); 88,8% demostraron resistencia a ampicilina y más de 42% a cefalosporinas de amplio espectro. El 22,9% presentó fenotipo BLEE positivo. Tener Apgar ≤ 7 a los cinco minutos de vida (OR 4,6; IC 95% 1,47-14,6) y edad gestacional < 37 semanas (OR 5,4; IC 95%1,04-27,7) incrementaron el riesgo. Conclusión: En las enterobacterias causantes de sepsis neonatal, 22,9% son EP-BLEE; la infección es más probable en pacientes con Apgar ≤ 7 a los cinco minutos de vida y en prematuros.

Introducción. La sepsis neonatal es una de las principales causas de muerte en recién nacidos. El tratamiento antimicrobiano empírico se sustenta en información epidemiológica y pruebas de susceptibilidad antimicrobiana. El objetivo del estudio fue describir los agentes etiológicos y su sensibilidad antimicrobiana enreciénnacidos con sepsis temprana (SNTe) o tardía (SNTa) de una Unidad de Terapia Intensiva Neonatal. Métodos. Estudio transversal realizado en un hospital de concentración del occidente de México. Se determinó la resistencia antimicrobiana de los gérmenes aislados en sangre o líquido cefalorraquídeo de pacientes con SNTe o SNTa nosocomial. Resultados. Se aislaron bacterias o levaduras en 235 cultivos de 67 eventos de SNTe y 166 eventos de SNTa. Del total de aislamientos, las bacterias más frecuentes fueron enterobacterias (51,5%), seguidas de Streptococcus spp. en SNTe y Staphylococcus spp. en SNTa. En cuanto a las enterobacterias de adquisición nosocomial, el 40% fueron productoras de betalactamasas de espectro extendido. En especies de Staphylococcus, la resistencia a oxacilina se registró en el 65,5%. En las enterobacterias (n: 121), la frecuencia de resistencia a amikacina, piperacilina-tazobactam y meropenem fue menor del 3%. En bacterias no fermentadoras, no se observó resistencia a amikacina, ciprofloxacino y cefepime; sin embargo, el número de aislamientos fue escaso. Conclusiones. Las bacterias identificadas con mayor frecuencia en SNTe fueron enterobacterias (67,6%) y Streptococcus spp. (17,6%), mientras que, en SNTa, fueron enterobacterias (44,9%) y Staphylococcus spp. (34,7%). El 40% de las enterobacterias de adquisición nosocomial fueron productoras de betalactamasas de espectro extendido y el 65,5% de Staphylococcus spp. mostraron resistencia a oxacilina.
