Probiotics for Prevention Neonatal Infection

Overview

Neonatal sepsis (serious infection) continues to be one of the major causes of morbidity and mortality in the newborn period around the world. India, with one of the world's largest populations, continues to struggle with extremely high infant and neonatal mortality rates. Sepsis accounts for 50% of deaths among community born (and 20% of mortality among hospital-born) infants. Closely linked with this is a burgeoning problem of antimicrobial resistance, which is increasingly restricting the therapeutic options for medical care providers. Friendly bacteria called "Probiotics" have been used in multiple infectious and inflammatory disease states in humans. Fructooligosaccharides are sugars found naturally in many fruits and vegetables and also in human breast milk. These sugars reach the colon undigested and serve as food for the friendly bacteria. The current study uses a probiotic preparation containing Lactobacillus plantarum and fructooligosaccharides as an attempt to prevent neonatal infections. Currently no conclusive data are available on the utility of probiotics in such conditions. If successful, such inexpensive preventive therapy can be made available to general public in resource poor countries. Similar preparations can also be used in the western world to prevent similar infectious conditions of the neonatal period, especially in preterm infants where sepsis continues to be a major cause of hospital stay and death.

Our current study is an attempt to put the well known concept of probiotics through rigorous scientific testing before it could be recommended as a prophylactic therapy against neonatal infections. The study will be conducted in India in 8,442 infants who will receive once daily dosing of probiotics for one week. They will be followed for 60 days at home. We have designed the study with enough power to detect a 20% drop in the incidence rate and plan to collect multiple other demographic data from the mothers and infants to help us discern the possible contribution of other confounding risk factors that have been implicated as cofactors in neonatal infection and death. This will be a randomized controlled clinical trial involving probiotics (Lactobacillus plantarum 10 billion bacteria and 150 mg of fructo-oligosaccharide). We will use our well established three tier monitoring system in the villages. Infants with any adverse event (including sepsis and other infections) will be brought to attached study hospitals for clinical care. Blood and/or CSG culture will be done using Bactec blood culture system and treatment will be provided based on clinical judgment and microbiological analysis of the blood/CSF and/or other findings such as chest X-ray. Data entry will be done on site and transmitted to the principal investigator's institution in the U.S. A data safety monitoring board convened by expert clinicians, neonatologists, and biostatisticians will monitor the study yearly and more frequently if required. Analyzed data will be published in appropriate journals.
