Clinical Study Evaluating the Safety of Lactobacillus Probiotic in Children With Drug Resistant Epilepsy

June 29, 2025 updated by: Amira Roshdy, Tanta University

Animal and human studies have brought up evidence supporting Gut microbial disbalance, namely dysbiosis, as a causative factor of epilepsy, especially the refractory form. thus, probiotics might constitute a safe, low-cost, and effective supplementary therapy in patients with DRE.

The Lactobacillus population is probiotic bacteria that have a beneficial role in epilepsy. Lactobacillus can influence brain function through the modulation of GABA, as shown in rodent models. Moreover, it has been demonstrated in animal models of epilepsy and in human epileptic patients that probiotic treatment aimed at restoring gut microbiota equilibrium has beneficial effects on epileptic symptoms by increasing GABA in animals and the levels of Bifidobacteria and Lactobacillus in humans.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
effectivness of Lactobacillus probiotics for controlling epileptic seizures in children with drug resistant epilepsy
Time Frame: 6 months
effectivness can be defined as more than 50% reduction in number of seizures.
6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
1. the change in the concentration of measured biological parameters (NLRP3, and GAD-Ab)
Time Frame: 6 months

Before and 6 months after intervention, 5 ml of venous blood will be withdrawn from each participant by antecubital venipuncture between 8 am and 11 am. Blood samples will be centrifuged at 3000 rpm for 15 min to separate sera. Sera will be kept at deep freeze (-80°C) until analysis of serum concentrations of :

  • Serum NLRP3 inflammasome level.
  • Serum glutamic acid decarboxylase antibody (GAD-Ab).
6 months
