Abstract

Background Preterm infants are at high risk of developing sepsis. An imbalance between the normal gut and pathogenic microbiomes, known as dysbiosis, has been proposed as a condition that leads to neonatal sepsis. Objective To assess for an association between gut dysbiosis and neonatal sepsis. Methods A prospective cohort study was conducted involving very preterm or very low birth weight infants admitted to the Neonatal Unit, Cipto Mangunkusumo Hospital, Jakarta, from November 2019 to January 2021. The primary outcome was proven and/or clinical neonatal sepsis. The independent variable was gut dysbiosis, defined as a ratio of normal-to-pathogenic gut microbiome <1.0. Gut microbiome analysis was performed using a polymerase chain reaction test from a fecal specimen. Multivariate analysis using multiple logistic regression was conducted with adjustments for potential confounders. Results Forty-three infants were recruited during the study period, with a median gestational age of 30 (range 25-36) weeks and birth weight of 1,170 (range 630-1855) grams. Among them, 28 (65.1%) infants had dysbiosis and 25 (58.2%) developed sepsis. The incidence of sepsis was higher among infants with dysbiosis (20 infants; 71.4%) than those without dysbiosis (5 infants; 33.3%). Dysbiosis and hemodynamically significant patent ductus arteriosus increased the risk of sepsis, with aOR 6.93 (95%CI 1.04 to 46.14; P=0.045) and aOR 22.7 (95%CI 1.45 to 355.29; P=0.026), respectively, after adjusting for sex, birthweight, maternal and infant morbidities, as well as maternal and infant vitamin D status. Conclusion Gut dysbiosis is a risk factor for neonatal sepsis. Maintaining the balance of the gut microbiome is essential from the first day of life.

Abstract

Carnitine (gamma-trimethylamino-beta­ hydroxybutyric acid) is a quaternary amine which is capable of forming esters with a variety of acyl groups and was first iden­tified by Gulawitsch and Krimberg in 1905. Carnitine deficiency was first noted by Fraenkel (1984) who observed that if cer­tain insects were fed a diet free of carnitine, they would die in four to five weeks. Since that time, intensive studies had been done and led to suggestion that a primary func­tion of carnitine was as a carrier molecule translocating long-chain fatty acids across the inner mitochondrial membrane to the matrix, where they underwent beta-oxida­tion (Friedman and Fraenkel, 1955). Carnitine is plentiful in human milk and milk-based infant formulas; however, it is lacking in supplemented soy formulas. Since newborn infant may not fully capable of synthesizing carnitine, they must receive an adequate intake of carnitine through the diet. This article describes some aspects of carnitine with special reference to the role of carnitine on fat metabolism.
