Clinical Trial Summary

To assess the effect of probiotics on cytokine's level(interleukin 6 and Transforming growth factor-β1)in children admitted to PICU with sepsis.

Description:

Sepsis, defined as an infection with deregulated host response leading to life-threatening organ dysfunction. Historically, the term sepsis has been used to characterize life-threatening infections usually caused by bacterial pathogens if untreated progress to shock and death, It contributes to 19% of all deaths globally, with the highest age-specific incidence in children younger than 5 years of age. Pediatric sepsis resulted in 0.7% of all hospital encounters. Epidemiologic studies found an incidence of pediatric sepsis in up to 8% of all pediatric intensive care unit (PICU) admissions, contributing to 1in 4 deaths in PICUs. Despite many advances in diagnosis and management, sepsis is associated with significant morbidity and mortality in pediatric population. The pathophysiology of systemic inflammatory response syndrome (SIRS)and sepsis is characterized by hyperactive and deregulated endogenous inflammatory mediators in a sequential manner resulting in a cytokine cascade. Cytokines are regulators of the immune response to infection and play a key role in regulating inflammation and trauma. There are two types of cytokines. Pro-inflammatory cytokines and anti-inflammatory cytokines. Pro-inflammatory cytokines(tumor necrosis factor [TNF]-α, interferon-γ, interleukin[IL]-1α, IL-1β, IL-6, IL-8, IL-12, IL-17) are important for initiation of an effective inflammatory response against pathogens, whereas their excess production can lead to multiple organ dysfunction syndrome (MODS) and mortality, on the other side, anti-inflammatory cytokines (IL-4, IL-10, IL-13,transforming growth factor [TGF]-β) are required for controlling and down-regulating the inflammatory response and if severe can lead to depression of the immune system. The levels of these cytokines rise within few hours of onset of sepsis and remain elevated for days together depending on severity and duration of sepsis, baseline host factors, timing of sampling relative to onset of sepsis/septic shock, and inter-individual variation. The gastrointestinal system seems to play a key role in the pathogenesis MODS owing to a breakdown of intestinal barrier function and increased translocation of bacteria and bacterial components into the systemic circulation. During critical illness, alterations occur in gut micro flora owing to change in circulating stress hormones, gut ischemia, immune suppression, the use of antibiotics, and lack of nutrients due to delay in starting enteral feeding. Probiotics are living micro-organisms that, when administered in adequate amounts, can help maintain the integrity of the intestinal barrier function by modulating the immune response. Such administration has been included in the management of critically ill patients as a therapeutic approach. Various studies highlighted that probiotics can modulate intestinal micro biota by colonizing human GIT, preventing overgrowth of pathogens, normalizing altered intestinal flora, reducing bacterial translocation, influencing immune system, and balancing control of pro-inflammatory and anti-inflammatory Cytokines.
