Abstract Objective: To evaluate the diagnostic utility of salivary C-reactive protein (CRP) and its potential correlation with serum CRP levels in full-term neonates with late-onset sepsis (LOS). Methods: This cross-sectional study included 90 neonates assigned to three equal groups: culture proven LOS, clinical LOS and a control group. Clinical findings and routine laboratory data including complete blood pictures and blood culture results were documented. Highly sensitive serum CRP was measured according to hospital protocol, while salivary CRP levels were measured using enzyme-linked immunosorbent assay. Results: The median serum CRP was significantly higher in septic neonates compared to controls (p < 0.001). For serum CRP, the optimum cut-off value for LOS diagnosis was found to be 7.2 mg/L with sensitivity, specificity, positive and negative predictive values of 91, 100, 100, and 85.7%, respectively. No significant difference was observed in levels of salivary CRP among the 3 study groups (p = 0.39). No correlation was found between the levels of salivary and serum CRP (r = 0.074, p = 0.49). Conclusion: Serum CRP, at a cut-off value of 7.2 mg/L, exhibited a high specificity and positive predictive value in LOS diagnosis, whereas salivary CRP levels weren't significantly different between the 3 study groups nor did they predict abnormal serum CRP thresholds in newborns with sepsis.

INTRODUCCIÓN: La malaria congénita (MC) es la infección por Plasmodium spp adquirida in útero o durante el parto y sus manifestaciones clínicas son inespecíficas. Puede causar enfermedad grave en la embaraza da y en el recién nacido. OBJETIVO: describir dos casos de MC causados por Plasmodium falciparum, diagnóstico diferencial de sepsis en recién nacidos de gestantes que hayan visitado o residan en áreas endémicas para malaria. CASOS CLÍNICOS: Neonatos de sexo femenino, nacidos en área no endémica para malaria, diagnosticados con sepsis neonatal y tratados con antibióticos sin respuesta clínica. Después de la primera semana de vida la gota gruesa identificó trofozoítos de Plasmodium falciparum y los neonatos recibieron tratamiento con quinina intravenosa con mejoría. Las madres de las recién nacidas tuvieron malaria en el embarazo, una de ellas recibió tratamiento y estaba asintomática y otra tenía malaria complicada al momento del parto. CONCLUSIONES: La MC puede causar enfermedad neonatal grave con manifestaciones clínicas inespecíficas y similares a la sepsis, el tratamiento oportuno disminuye el riesgo de malaria complicada. Es un diagnóstico diferencial en recién nacidos de mujeres con malaria durante el embarazo o gestantes que visiten o residan en áreas endémicas.

INTRODUCTION: Congenital malaria (CM) is a Plasmodium spp infection acquired in utero or during delivery with nonspecific clinical manifestations. Plasmodium falciparum can cause severe illness in pregnant wo men and newborns. OBJECTIVE: to describe two cases of CM caused by Plasmodium falciparum, di fferential diagnosis of sepsis in newborns of pregnant women who live in or have visited endemic malaria zones. CLINICAL CASES: Female neonates born in a non-endemic malaria area, diagnosed with neonatal sepsis and treated with antibiotics without clinical response. After the first week of life, the peripheral blood smear identified trophozoites of Plasmodium falciparum thus the newborns were treated with intravenous quinine, improving their condition. The mothers of the two newborns who had malaria in pregnancy, one of them received treatment and she was asymptomatic, and the other one had severe malaria at the time of delivery. CONCLUSIONS: CM can cause severe neonatal disease with non-specific, sepsis-like clinical manifestations in which early treatment decreases the risk of complicated malaria. It is a differential diagnosis in newborns of women with a history of malaria during pregnancy or pregnant women visiting or living in endemic malaria areas.

Introducción. El objetivo fue determinar la relación entre la concentración materna e infantil de vitamina D y la sepsis de aparición tardía. Población y métodos. En este estudio se incluyó a los bebés nacidos con ≥ 37 semanas de gestación hospitalizados con diagnóstico de sepsis de aparición tardía. Se comparó la concentración de vitamina D de los niños y sus madres del grupo del estudio y del de referencia. Resultados. El grupo del estudio incluyó a 46 pacientes con sepsis de aparición tardía nacidos a término y el grupo de referencia, 46 pacientes con hiperbilirrubinemia. La suplementación con vitamina D durante el embarazo fue menor en las madres del grupo del estudio que en el de referencia (p = 0,001). La concentración sérica de 25-hidroxivitamina D [25(OH)D] de los niños y las madres del grupo del estudio fue significativamente menor que la del grupo de referencia (p < 0,001). Se observó una correlación positiva entre la 25(OH)D en las madres y los niños de ambos grupos (r: 0,38; p < 0,001). El valor de corte para la 25(OH)D, que determina el riesgo de sepsis neonatal de aparición tardía, se estableció en 15,45 ng/ml (sensibilidad: 91,3 %; especificidad: 71,7 %; área bajo la curva: 0,824; p < 0,001). Conclusiones. La concentración de 25(OH)D fue inferior en los bebés nacidos a término con sepsis de aparición tardía y sus madres en comparación con el grupo de referencia. La correlación entre la concentración sérica de 25(OH)D de los niños y sus madres fue positiva.

Introduction. The objective was to determine the relationship between mother and infant vitamin D levels and late onset sepsis. Population and methods.Infants born ≥37 weeks of gestational age who were hospitalized with the diagnosis of late-onset sepsis were enrolled to this prospective case control study. VitaminD levels of the infants and their mothers in the study and a control group were compared. Results. Fourty six term patients with lateonset sepsis composed the study group, 46 patients with hyperbilirubinemia as the control group. Vitamin D supplementation during pregnancy was lower in mothers of study group compared to the control group (p = 0.001). Serum 25-hydroxyvitamin D levels of infants and mothers in the study group were significantly lower than the control group (p < 0.001). There was a positive correlation between 25-hydroxyvitaminD levels of mothers and infants in both groups (r: 0.38, p < 0.001). The best cut off value of 25-hydroxyvitamin D, which determines the risk of late-onset sepsis in neonates, was detected as 15.45 ng/ml (sensitivity: 91.3 %, specificity: 71.7 %, area under the curve: 0.824, p < 0.001). Conclusions.In this study, 25-hydroxyvitaminD levels were found to be lower in term infants with late-onset sepsis and among their mothers compared to the control group. Positive correlation was found between serum 25(OH)D levels of infants and their mothers. Key words: newborn infant, sepsis,

Abstract Objectives To present current evidence on the etiology, risk factors, diagnosis, and management of early and late neonatal sepsis. Source of data Non-systematic review of the Medline (PubMed), Scopus, Web of Science, Cochrane, and Google Scholar databases regarding the following terms: neonatal sepsis, early neonatal sepsis, late neonatal sepsis, empirical antibiotic therapy, sepsis calculator, vancomycin, newborn, preterm newborn. Data synthesis Neonatal sepsis is a frequent cause of neonatal morbidity and mortality. Its diagnosis is difficult. Continuous observation of the patient is critical to diagnostic suspicion. When neonatal sepsis is suspected, bacteriological tests should be collected. Vancomycin should not be routinely using in the empirical antibiotic regimen in late neonatal sepsis, and the main protective mechanisms against neonatal sepsis are handwashing and the use of breast milk. Conclusions Newborns constitute a group that is more vulnerable to sepsis. Knowledge of risk factors and etiological agents allows a better approach to the newborn with sepsis.

Resumo Objetivos Apresentar evidências atuais na etiologia, fatores de risco, diagnóstico e manejo da sepse neonatal precoce e tardia. Fontes de dados Revisão não sistemática feita nas bases de dados Medline (PubMed), Scopus, Web of Science, Cochrane, Google Scholar sobre os temas sepse neonatal, sepse neonatal precoce, sepse neonatal tardia, antibioticoterapia empírica, sepsis calculator, vancomicina, recém-nascido, recém-nascido pré-termo. Síntese de dados A sepse neonatal é uma causa frequente de morbimortalidade neonatal. O seu diagnóstico é difícil. A observação contínua do paciente é fundamental para uma suspeição diagnóstica. Ao se suspeitar de sepse neonatal devem-se coletar exames bacteriológicos. Não usar, rotineiramente, vancomicina no esquema empírico de antibiótico na sepse neonatal tardia. Os principais mecanismos protetores da sepse neonatal são a lavagem de mãos e o uso do leite materno. Conclusões Os recém-nascidos constituem um grupo mais vulnerável à sepse. O conhecimento dos fatores de risco e dos agentes etiológicos permite uma melhor abordagem do recém-nascido séptico.

OBJECTIVE@#To study the clinical significance and cut-off value of white blood cell (WBC) count in the diagnosis of early-onset sepsis (EOS) in neonates.@*METHODS@#A retrospective analysis was performed on 306 neonates with EOS who were admitted from January 2019 to March 2020. A total of 580 children without infection who were admitted during the same period of time were enrolled as the control group. General status and WBC count were compared between the two groups. The diagnostic value of WBC count was analyzed based on the diagnostic and therapeutic protocol of neonatal sepsis in 2003 (referred to as the 2003 diagnostic and therapeutic protocol) and the expert consensus on the diagnosis and treatment of neonatal sepsis (2019 edition) (referred to as the 2019 expert consensus).@*RESULTS@#According to the two different diagnosis and treatment protocols, the statistical analysis showed that WBC count had a relatively positive rate (51.3% and 32.0% respectively) but a relatively high specificity (93.3% and 98.6% respectively). The receiver operating characteristic (ROC) curve analysis showed that the area under the ROC curve of WBC count in the 2003 diagnostic and therapeutic protocol was larger than that in the 2019 expert consensus (P<0.05).@*CONCLUSIONS@#The cut-off value of WBC ≥25×10

INTRODUCCIÓN: Múltiples factores influyen en el riesgo de morbimortalidad del prematuro con restricción del crecimiento intrauterino (RCIU). La comparación de gemelos con crecimiento intrauterino discordante permite evaluar su efecto, excluyendo factores maternos y manejo prenatal. Nuestro objetivo fue evaluar el efecto de la RCIU sobre la morbilidad aguda, crónica y mortalidad, en parejas de recién nacidos gemelares prematuros extremos. PACIENTES Y MÉTODO: Gemelos menores de 1500 g y 30 semanas de gestación, de la Red Neocosur. Se realizaron análisis separados de pares de gemelos concordantes, discordantes leves y severos, evaluando el efecto de la RCIU sobre morbi-mortalidad. Se realizó análisis multivariado para establecer magnitud del efecto. RESULTADOS: 459 pares de gemelos, 227 concordantes, 110 discordantes leves y 122 severos. Entre los concordantes solo hubo diferencia en uso de oxígeno a las 36 semanas. En discordantes leves, el menor tuvo menos enfermedad de membrana hialina y requirió menos dosis de surfactante, pero tuvo un mayor riesgo de Displasia broncopulmonar (DBP) o muerte. En discordantes severos, el menor presentó mayor mortalidad, sepsis, utilización y permanencia en ventilación mecánica, pese a menor frecuencia de enfermedad de membrana hialina. En regresión múltiple, el riesgo combinado de DBP o muerte fue mayor en gemelo menor y discordante severo. CONCLUSIÓN: En gemelos discordantes, la patología respiratoria aguda fue más frecuente en el gemelo mayor, aunque el riesgo de DBP o muerte fue mayor en el gemelo con RCIU.

INTRODUCTION: Multiple factors influence the risk of morbidity and mortality of premature infants with intrauterine growth restriction (IUGR). The comparison of twins with different intrauterine growth allows evaluating the effect of the restriction, excluding maternal factors and prenatal mana gement. Our objective was to assess the effect of IUGR on acute and chronic morbidity, and mortality of extreme preterm twins. PATIENTS AND METHOD: Twins weighing less than 1500 grams and gesta tion equal to or less than 30 weeks, of the Neocosur Network. Separate analyses were performed on concordant twin pairs, and on mild and severe discordant twins, evaluating the effect of IUGR on morbidity and mortality. A multivariate analysis was performed in order to establish the impact of this effect. RESULTS: 459 twin pairs, 227 concordant twins, 110 of mild discordance, and 122 of severe discordance. Among the concordant ones, there was only a difference in oxygen uptake at 36 weeks. In those of mild discordance, the smaller twin presented a lower frequency of hyaline membrane disease and required fewer doses of surfactant, but had a higher risk of bronchopulmonary dysplasia (BPD) or death. In severe discordant twins, the smaller one presented higher mortality, sepsis, use and permanence in mechanical ventilation, despite the lower frequency of hyaline membrane disease. In multiple regression analysis, the combined risk of BPD or death was higher in the smaller twin and of severe discordance. CONCLUSION: In discordant twins, the acute respiratory pathology was more frequent in the larger one, although the risk of BPD or death was higher in the one with IUGR.

La sepsis es la principal causa de mortalidad neonatal. La forma precoz, habitualmente, está relacionada con la colonización recto-vaginal u otros factores de riesgo materno. En la forma tardía, es difícil establecer su origen; por lo general, es nosocomial o de la comunidad. El Streptococcus agalactiae (Streptococcus beta-hemolítico del grupo B) es el germen implicado con más frecuencia en la sepsis neonatal en países desarrollados. La forma tardía, generalmente, se presenta con septicemia y meningitis, y, en ocasiones, pueden detectarse infecciones osteoarticulares o de piel y tejidos blandos. El síndrome celulitis-adenitis en la región cervical, forma poco frecuente de presentación, es causado por Staphylococcus aureus y, ocasionalmente, por Streptococcus agalactiae. Se reportan 2 casos de sepsis neonatal tardía con clínica de celulitis-adenitis cervical causados por Streptococcus beta-hemolítico del grupo B, con una evolución satisfactoria con terapia antibiótica de amplio espectro.

Septicemia is the main cause of neonatal mortality. The early-onset neonatal sepsis is usually related to maternal factor risks including recto-vaginal colonization. In the late-onset neonatal septicemia it is more difficult to establish the etiology because the majority of the cases are nosocomial or community related. The Streptococcus agalactiae (beta-hemolytic Streptococcus) is the most frequent germ associated with neonatal sepsis in developed countries. The late-onset form usually occurs with septic symptoms and meningitis and, in a few cases, with osteoarticular, skin and soft tissue infection. Adenitis-cellulitis syndrome is rarely seen, and its main cause is Staphylococcus aureus, followed by Streptococcus agalactiae. We report two cases of group B Streptococcus late-onset neonatal septicemia, both of them with adenitis-cellulitis syndrome. Patients recovered uneventfully after an adequate antibiotic therapy.

SUMMARY BACKGROUND: To determine the concentration of the Lipid Peroxidation Marker: Malondialdehyde (MDA), and Antioxidant Markers: Superoxide Dismutase (SOD), Glutathione Peroxidase (GPX), Catalase (CAL) in umbilical cord blood and in unstimulated saliva in the first 24 and 48 hours of life in the PTNB of mothers with and without risk factors for early-onset neonatal sepsis. METHODS: Cross-sectional study with the signing of informed consent by the pregnant women and application of a standard questionnaire classifying the PTNB in Group 1 or 2. RESULTS: Twenty-one PTNB were studied. Regarding gender, birth weight, need for oxygen, use of phototherapy, diagnosis of assumed sepsis, presence of fetal distress, number of pregnancies, type of delivery, use of corticosteroids, premature rupture of membranes, maternal fever, chorioamnionitis, APGAR at the 5th and 10th minute of life. Statistical analysis was performed with the Mann-Whitney test (p = 0.019) on the GPX variable of umbilical cord blood in the group of mothers with risk factors for early-onset neonatal sepsis. There was no statistical difference in the MDA, SOD, and CAT variables of the group with risk factors and in any variable of the group without risk factors. CONCLUSION: There was an increase of the GPX concentration in the blood from the umbilical vein in the group with risk factors for early-onset neonatal sepsis. There was no statistical significance in the comparison of saliva and umbilical cord blood. There was no statistically significant difference in MDA, SOD, CAT.

Abstract Objective: To assess the applicability of salivary C-reactive protein, mean platelet volume, neutrophil-lymphocyte ratio, and platelet lymphocyte ratio in the diagnosis of neonatal sepsis. Methods: Prospective case-control study of 70 full-term neonates, 35 with sepsis (20 with proven sepsis and 15 with clinical sepsis) and 35 healthy controls. Serum and salivary C-reactive protein concentrations were measured by enzyme-linked immunosorbent assay while mean platelet volume, neutrophil-lymphocyte ratio, and platelet lymphocyte ratio were measured by automated blood cell counter. Results: This study showed statistically significant difference of mean salivary C-reactive protein between septic neonates and controls (12.0 ± 4.6 ng/L vs. 2.8 ± 1.2 ng/L) respectively. At a cut-off point of 3.48 ng/L, salivary C-reactive protein showed 94.3% sensitivity and 80% specificity. Salivary C-reactive protein also showed good predictive accuracy for predicting elevated serum C-reactive protein values in septic neonates. Mean platelet volume and neutrophil-lymphocyte ratio showed significant difference between septic neonates and controls (10.2 ± 1.2 fL vs.8.0 ± 0.5 fL; 2.9 ± 1.7 vs. 1.6 ± 0.4, respectively). At a cut-off point of 10.2 fL, mean platelet volume presented 80% sensitivity and specificity. At a cut-off point of 2.7, neutrophil-lymphocyte ratio presented 80% sensitivity and 57.1% specificity. Conclusion: This study provides support for further studies on the usefulness of salivary C-reactive protein, mean platelet volume, and neutrophil-lymphocyte ratio as diagnostic markers for neonatal sepsis.

Resumo Objetivo: Avaliar a aplicabilidade da proteína C reativa salivar, do volume médio de plaquetas, a proporção de neutrófilos-linfócitos e a proporção de plaquetas/linfócitos no diagnóstico de sepse neonatal. Métodos: Estudo caso-controle prospectivo de 70 neonatos a termo, 35 com sepse (20 com sepse comprovada e 15 com sepse clínica) e 35 controles saudáveis. As concentrações de PCR no soro e salivar foram medidas por ensaio imunossorvente ligado a enzima (Elisa), ao passo que o VMP, PNL e PPL foram medidos por contador de células sanguíneas automatizado. Resultados: Este estudo mostrou uma diferença estatisticamente significativa da média de PCR salivar entre os neonatos com sepse e os controles (12,0 ± 4,6 ng/L em comparação com 2,8 ± 1,2 ng/L), respectivamente. Um ponto de corte 3,48 ng/L na PCR salivar mostrou sensibilidade de 94,3% e especificidade de 80%. A PCR salivar mostrou, ainda, boa precisão preditiva para prever altos valores de PCR no soro em neonatos com sepse. O VMP e a PNL mostraram diferença significativa entre os neonatos com sepse e os controles (10,2 ± 1,2 fL em comparação com 8,0 ± 0,5 fL), (2,9 ± 1,7 em comparação com 1,6 ± 0,4), respectivamente. O VMP no ponto de corte 10,2 fL apresentou 80% de sensibilidade e especificidade. A PNL no ponto de corte 2,7 fL apresentou 80% de sensibilidade e 57,1% de especificidade. Conclusão: Este estudo fornece uma base para outros estudos na utilidade da PCR salivar, VMP e PNL como marcadores de diagnóstico de sepse neonatal.

Resumen Introducción: El dengue perinatal es una patología de la que poco se sabe, los reportes disponibles describen riesgo de resultados perinatales adversos. Objetivo: Reportar un caso de dengue perinatal, como diagnóstico diferencial de sepsis neonatal, que debe tenerse en cuenta en zonas endémicas. Caso clínico: Recién nacido de una mujer de 23 años quien a las 36 semanas de gestación presentó cuadro de dengue con antígeno Non-Structural Protein 1 (NS1) positivo y anticuerpos anti-dengue negativos. Al sexto día de enfermedad dio a luz a un recién nacido sano, quien, al segundo día de vida, presentó fiebre sin otros hallazgos patológicos al examen físico, asociado a trombocitopenia severa (17.900 plaquetas/uL) y aumento de la proteína C reactiva, antígeno viral NS1 positivo e in-munoglobulina G (IgG) anti dengue positiva. Fue manejado con antibióticoterpia con ampicilina y gentamicina por protocolo de la institución para sepsis neonatal probable. El neonato mostró me joría clínica, con estabilidad hemodinámica y aumento significativo de plaquetas, siendo dado de alta. Conclusiones: El dengue en el embarazo trae consigo el riesgo de resultados perinatales adver sos, particularmente bajo peso al nacer y parto pre-término. Los hijos de madres diagnosticadas con dengue al final del embarazo deberían ser observados estrechamente con realización de hemograma seriado en los primeros días de vida, debido al riesgo de transmisión vertical.

Abstract Introduction: Few reports are available about perinatal dengue, with controversial results in regards the risk of perinatal outcome. Objective: To report a case of perinatal dengue as a differential diagno sis with neonatal sepsis, which must be considered in endemic areas. Clinical case: Male newborn of a 23 year-old female, who presented a Non-Structural Protein 1 (NS1) antigen positive to dengue at 36 weeks of gestation and negative anti-dengue antibodies. At day six of the illness a healthy newborn was born. On the second day of life the neonate presented fever with no other pathological findings on the physical exam, associated with severe thrombocytopenia (17,900 platelets/uL), increased C-reactive protein, a positive NS1 antigen, and positive anti-dengue immunoglobulin G (IgG). He was treated with ampicillin and gentamicin according the Institution protocol of neonatal sepsis. The newborn showed clinical improvement, with hemodynamic stability and significant increase of platelets, receiving the medical discharge. Conclusions: Dengue in pregnancy produces the risk of adverse perinatal outcomes, particularly low birth weight and preterm delivery. Children of mothers diagnosed with dengue at the end of pregnancy should be observed closely with serial hemograms during child's first days of life, due to the high risk of vertical transmission.

Early Onset Neonatal Sepsis (EONS) is a clinical situation resulting from the invasion andproliferation of bacteria, fungi or viruses in the newborn (NB) bloodstream, which occurs within the first 72hours of life. To determine the diagnostic usefulness of laboratory tests performed on infants with suspicion ofearly neonatal sepsis at the Santa Barbara Integrated Hospital, Honduras. A case-control study was carried outduring 2016; the cases were 20 infants with early onset neonatal sepsis, and the controls were 40 infants whowere admitted as potentially septic, but the blood culture result was negative. Sensitivity, specificity, positivepredictive value (PPV) and negative (NPV) of leukocytosis, platelets, initial C-reactive protein (CRP) and controlwere calculated. Data were analyzed with SPSS version 19. It was found that 17 (28.3 %) NB were women and43 (71.7 %) were men. The VPP of the initial PCR was 5 %, increasing to 85 % in the control study. The isolatedmicroorganism was enterobacter in 6 (30 %) of the RNs. Of the 23 (38.3 %) neonates who presentedcomplications; 11 (48 %) had positive blood culture and 12 (52 %) had negative blood cultures. The dischargecondition was medical discharge in 55 (92 %) and referred to a more complex hospital 5 (8 %) of the neonates.The VPP of the C-reactive protein increases considerably when doing a laboratory control,between 24-48 hours.

Sepsis neonatal temprana es aquella situación clínica derivada de la invasión y proliferación de bacterias, hongos o virus en el torrente sanguíneo del recién nacido (RN), que se presenta en las primeras 72 horas de vida. Determinar la utilidad diagnóstica de los exámenes de laboratorio que se realizan a los RN con sospecha de sepsis neonatal temprana, en el Hospital Santa Bárbara Integrado (HSBI), Honduras. Se realizó un estudio de casos y controles, durante el año 2016, los casos fueron 20 RN con sepsisneonatal temprana comprobada por hemocultivo y los controles 40 RN que ingresaron como potencial mentesépticos, pero el resultado de hemocultivo fue negativo. Se calculó sensibilidad, especificidad, valor predictivo positivo (VPP) y negativo (VPN) de leucocitosis, plaquetas, proteína C reactiva (PCR) inicial y la de control. Los datos fueron analizados con el programa SPSS versión 19. Se encontró que 17 (28.3 %) RN eran mujeres y 43(71.7 %) hombres. El VPP de la PCR inicial fue 5 %, aumentando a 85% en el estudio de control. El microorganismo aislado fue enterobacter en 6 (30 %) de los RN. De los 23 (38.3 %) neonatos que presentaron complicación; 11 (48 %) tenían hemocultivo positivo y 12 (52 %) tenían hemocultivo negativo. La condición de egreso fue alta médica en 55 (92 %) y referido a un hospital de mayor complejidad 5 (8 %)de los neonatos. El VPP, de la proteína C reactiva, aumenta considerablemente al hacer un control laboratorial,entre 24-48 horas.

Sepsis neonatal Temprana es la infección comprobada que se presenta en el recién nacido antes de las 72 horas de vida. El objetivo fue determinar las características epidemiológicas y clínicas de los recién nacidos con sepsis temprana, atendidos en Hospital Santa Bárbara Integrado, durante enero 2014 a diciembre 2015. Se realizó un estudio cuantitativo, descriptivo, trasversal en sala de Neonatología de dicho Hospital. El universo; 1,146 y la muestra 136 obtenida mediante muestreo aleatorio probabilístico sistemático. La recolección de datos fue mediante cuestionario validado por juicio de expertos. Se realizó el análisis con el paquete estadístico SPSS, versión 19. La prevalencia de sepsis neonatal temprana fue 60,6 %, la edad materna osciló entre 15-43 años, con moda de 21 y media 25,7 años, 92 % (125) procedían del área rural,40,4 % (55) eran analfabetas, 36,8 % (50) eran primigestas. 59 % (80) se realizaron 5 o más controles prenatales, de los que 89 (65,4 %) fueron realizados en Centro de Salud con médico. 44,0 % (30) presentaron Infección del tracto urinario sin tratamiento antes del parto. 53,7 % (73) de los RN eran del sexo masculino, 26,5 % (36) presentaron fiebre en las primeras horas de vida, se encontró que 22 (16,2 %) delos recién nacidos presentaron complicaciones. La condición de egreso fue; alta médica 127 (93,4 %), 9 (6,6%) fueron referidos a hospital de mayor complejidad y ninguno falleció. La prevalencia de sepsis neonatal temprana en dicho Hospital es alta, se presenta más frecuentemente en hijos de madres primigestas, analfabetas, con infecciones del tracto urinario sin tratamiento y vaginosis y en neonatos masculinos.
