Abstract
The efficacy of probiotics, prebiotics, or synbiotics in children and adolescents with overweight or obesity remains uncertain. This systematic review evaluates their intervention effects through a network meta-analysis of randomized clinical trials (RCTs). Searches of 4 electronic databases until January 7, 2024, yielded 17 papers reporting on 15 RCTs involving 820 participants. Multiple-strain probiotics (MSP) showed significant efficacy in reducing BMI (Mean Difference (MD) -2.13 kg/m2, 95% credible interval (CrI) [-2.7, -1.57]), waist circumference (MD -1.34 cm, 95% CrI [-2.33, -0.35]), total cholesterol (MD -6.55 mg/dL, 95% CrI [-10.61, -2.45]), triglycerides (MD -3.71 mg/dL, 95% CrI [-5.76, -1.67]), leptin (MD -3.99 ng/mL, 95% CrI [-4.68, -3.3]), and hypersensitive C-reactive protein (Hs-CRP) (MD -1.21 mg/L, 95% CrI [-1.45, -0.97]). Synbiotics were effective in reducing BMI-z score (MD -0.07, 95% CrI [-0.10, -0.04]) and LDL-C (MD -1.54 mg/dL, 95% CrI [-1.98, -1.09]) but led to a slight increase in fasting glucose (MD 1.12 mg/dL, 95% CrI [0.75, 1.49]). Single-ingredient prebiotics and single-strain probiotics also had some beneficial effects on BMI and Hs-CRP, respectively. Moderate to low evidence suggests MSP may be a potential choice for improving BMI and reducing lipids, leptin, and Hs-CRP levels, implying that MSP could aid in managing pediatric obesity and related metabolic issues by modulating the gut microbiota. Although synbiotics show their favorable effects on body metrics and lipid control, their potential impact on blood glucose currently prevents them from being an alternative to MSP for treating pediatric obesity. Further large-scale, well-designed studies are needed to confirm these findings.

Abstract
Objectives Adiponectin (ADN) is related to insulin resistance and cardiovascular disorders risks. It is negatively controlled in obese cases among diabetes mellitus type 1 (DMT1) patients. The current study evaluates ADN levels in early-aged children 9-12 years old of obese and non-obese cases (DMT1). Methods A cross-sectional study among children aged 9-11 years old, was conducted during the year 2023 within two groups. First was a diabetic children DMT1 group excluding diabetic cases with complications. Second was a healthy children's control group. Two groups were subdivided into two subgroups, obese and non-obese (n = 6 for each subgroup). ADN concentrations were measured in DMT1 cases related to weight and body mass index among treated and non-treated with insulin-therapy compared to in vitro diabetic rats. Adult albino male rats enrolled in a control group, non-treated diabetic, and insulin-treated diabetic rats. Statistical analysis-based measuring means and standard deviation for each group and comparing them with the student t-test. Results Significantly increased plasma AND levels were detected in DMT1 patients compared to non-diabetic cases (P < 0.001). AND levels were decreased in obese rather than non-obese cases of control or diabetic cases (P < 0.001). Data shows significantly increased plasma AND levels in experimental rats, induced with diabetes (with or without insulin treatment) compared to the control group (P < 0.001). Conclusion Plasma ADN levels were significantly reduced in obese subjects' diabetics or non-diabetics. It may refer to insulin resistance or mechanisms that prevent further weight gain by decreasing insulin sensitivity and increasing energy expenditure.

Abstract
Obesity in adolescence is increasing in frequency and is associated with elevated proinflammatory cytokines and chronic pain in a sex-dependent manner. Dietary probiotics may mitigate these detrimental effects of obesity. Using a Long-Evans adolescent and adult rat model of overweight (high-fat diet (HFD) - 45% kcal from fat from weaning), we determined the effect of a single-strain dietary probiotic [Lactiplantibacillus plantarum 299v (Lp299v) from weaning] on the theoretically increased neuropathic injury-induced pain phenotype and inflammatory cytokines. We found that although HFD increased fat mass, it did not markedly affect pain phenotype, particularly in adolescence, but there were subtle differences in pain in adult male versus female rats. The combination of HFD and Lp299v augmented the increase in leptin in adolescent females. There were many noninteracting main effects of age, diet, and probiotic on an array of cytokines and adipokines with adults being higher than adolescents, HFD higher than the control diet, and a decrease with probiotic compared with placebo. Of particular interest were the probiotic-induced increases in IL12p70 in female adolescents on an HFD. We conclude that a more striking pain phenotype could require a higher and longer duration caloric diet or a different etiology of pain. A major strength of our study was that a single-strain probiotic had a wide range of inhibiting effects on most proinflammatory cytokines. The positive effect of the probiotic on leptin in female adolescent rats is intriguing and worthy of exploration.NEW & NOTEWORTHY A single-strain probiotic (Lp299v) had a wide range of inhibiting effects on most proinflammatory cytokines (especially IL12p70) measured in this high-fat diet rat model of mild obesity. The positive effect of probiotic on leptin in female adolescent rats is intriguing and worthy of exploration.

Front Nutr 2023; 10:1291853. [PMID: 38192650 PMCID: PMC10773723 DOI: 10.3389/fnut.2023.1291853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Accepted: 11/27/2023] [Indexed: 01/10/2024] Open
Abstract
In the past two decades, the rapid increase in the incidence of metabolic diseases, including obesity, diabetes, dyslipidemia, non-alcoholic fatty liver disease, hypertension, and hyperuricemia, has been attributed to high-fat diets (HFD) and decreased physical activity levels. Although the phenotypes and pathologies of these metabolic diseases vary, patients with these diseases exhibit disease-specific alterations in the composition and function of their gut microbiota. Studies in germ-free mice have shown that both HFD and gut microbiota can promote the development of metabolic diseases, and HFD can disrupt the balance of gut microbiota. Therefore, investigating the interaction between gut microbiota and HFD in the pathogenesis of metabolic diseases is crucial for identifying novel therapeutic strategies for these diseases. This review takes HFD as the starting point, providing a detailed analysis of the pivotal role of HFD in the development of metabolic disorders. It comprehensively elucidates the impact of HFD on the balance of intestinal microbiota, analyzes the mechanisms underlying gut microbiota dysbiosis leading to metabolic disruptions, and explores the associated genetic factors. Finally, the potential of targeting the gut microbiota as a means to address metabolic disturbances induced by HFD is discussed. In summary, this review offers theoretical support and proposes new research avenues for investigating the role of nutrition-related factors in the pathogenesis of metabolic disorders in the organism.
