Inflammatory cytokines and lipid profile in children and adolescents with nephrotic syndrome receiving L. Plantarum: a randomized, controlled feasibility trial

This study aimed to evaluate the efficacy of the action of the Lactobacillus Plantarum probiotic as a immunomodulatory and hypolipidemic agent in dyslipidemic nephrotic children and adolescents. METHODS: This is a randomized, double-blind, placebo-controlled clinical trial in pediatric, compensated or partially compensated nephrotic syndrome and dyslipidemic subjects undergoing regular outpatient follow-up. Serum lipid and TNF-alpha (proinflammatory) and IL-10 (anti-inflammatory) cytokine variations were evaluated. Cytokines were analyzed by enzyme-linked immunosorbent assay (ELISA). RESULTS: In the probiotic group there was a tendency to reduce TNF-alpha levels and increase IL-10 levels when compared to controls. Regarding the lipid profile, there was a decrease in serum triglyceride (6.0 mg / dL) and total cholesterol (41.5 mg / dL) levels in the probiotic group when compared to baseline levels, while in the control group there was an increase in serum triglyceride (49.5 mg / dL) and total cholesterol (8.0 mg / dL) levels, respectively. CONCLUSION: Preliminary results suggest that L. Plantarum showed an immunomodulatory and hypolipidemic effect in nephrotic and dyslipidemic pediatric subjects.
