ABSTRACT
PURPOSE: Neonatal sepsis is an important public health concern worldwide due to its immediate lethality and long-term morbidity rates, Clinical evaluation and laboratory analyses are indispensable for diagnosis of neonatal sepsis. However, assessing multiple biomarkers in neonates is difficult due to limited blood availability. The aim is to investigate if the neonatal sepsis in preterm could be identified by multiparameter analysis with flow cytometry. MATERIALS AND METHODS: The expression of activation-related molecules was evaluated by flow cytometry in newborn with or without risk factors for sepsis. RESULTS: Our analysis revealed that several markers could be useful for sepsis diagnosis, such as CD45RA, CD45RO, or CD71 on T cells; HLA-DR on NKT or classic monocytes, and TREM-1 on non-classic monocytes or neutrophils. However, ROC analysis shows that the expression of CD45RO on T lymphocytes is the only useful biomarker for diagnosis of neonatal late-onset sepsis. Also, decision tree analyses showed that CD45RO plus CD27 could help differentiate the preterm septic neonates from those with risk factors. CONCLUSIONS: Our study shows a complementary and practical strategy for biomarker assessment in neonatal sepsis.

El aumento en la sobrevida de los recién nacidos prematuros, las características del cuidado neonatal y la escasez de programas para la prevención, detección y tratamiento de la retinopatía del prematuro provocan que esta enfermedad sea la principal causa de ceguera infantil prevenible en México. El advenimiento de agentes antiangiogénicos de uso oncológico, y su uso -no autorizado, aunque con buenos resultados- en el tratamiento de enfermedades vaso proliferativas en la retina del paciente adulto, así como la presencia de reportes anecdóticos en la literatura y series de casos con serias fallas metodológicas han sugerido su utilización en el tratamiento de la retinopatía del prematuro. Desafortunadamente, estos agentes, utilizados indiscriminadamente, presentan absorción sistémica y causan efectos secundarios en el organismo del paciente prematuro. Además, no existen estudios de seguimiento a largo plazo que garanticen la seguridad de su uso en esta población. El presente artículo describe la situación en nuestro país y advierte sobre los riesgos de estos medicamentos en la población de pacientes prematuros.
The increase in survival rates among preterm infants, characteristics of neonatal care for such infants and a lack of suitable programs for preventing, detecting and treating retinopathy of prematurity (ROP) are factors that have made this disease the main cause of preventable blindness among children in Mexico. The advent of antiangiogenic agents in cancer treatment and their off-label use with favorable results in the treatment of proliferative vessel disease of the retina among adult patients, as well as anecdotal reports in the literature and a series of cases showing serious methodological flaws, have prompted their use in the treatment of retinopathy of prematurity. Unfortunately, these agents used indiscriminately in our country have a systemic absorption and secondary effects on the preterm patient's body. There are no long-term monitoring studies that guarantee their safe use in this segment of the population. This article describes the situation in our country and warns of the risks posed by the use of this type of drug on the preterm infant population.
