Peer-Reviewed Studies
Abstract
Despite preclinical studies demonstrating the efficacy of l-carnitine supplementation for weight management, findings in clinical setting are contradictory. Electronic bibliographical databases were systematically searched up to February 2019 with no limitation in language, including Scopus, PubMed, ISI Web of Science and Cochrane Library. Clinical trials registry platform were also searched. All randomized controlled trials (RCTs) which reported an effect of l-carnitine supplementation on obesity-related indices were included. Weighted mean difference (WMD) was estimated using a random-effect model (DerSimonian-Laird method). Eventually 43 eligible RCTs were included for quantitative analysis. Meta-analysis results revealed that l-carnitine supplementation significantly decreased weight (WMD: -1.129 kg, 95 % CI: -1.590, -0.669; I2: 63.4), body mass index (BMI) (WMD: -0.359 kg/m2, 95 % CI: -0.552, -0.167; I2: 85.2) and fat mass (WMD: -1.158 kg, 95 % CI: -1.763, -0.554, I2: 15.5). However, l-carnitine supplementation did not change body fat percentage (WMD: -0.874 %, 95 % CI: -1.890, 0.142, I2: 98.2) or waist circumference (WMD: -0.883 mg/dl, 95 % CI: -1.770, 0.004, I2: 74.8). l-Carnitine supplementation changed weight (r = -0.98) and BMI (r = -0.67) in a non-linear fashion based on carnitine dosage and BMI according to trial duration (r = -0.04). Interestingly subgroup analysis revealed that l-carnitine showed anti-obesity effects only in overweight and obese subjects; l-carnitine decreased weight, and BMI alone when combined with other lifestyle modifications. Anthropometric indexes were not changed following l-carnitine supplementation among patients' undergoing hemodialysis. Our study revealed that l-carnitine supplementation might have a positive effects in achieving an improved body weight and BMI especially in overweight and obese subjects.
Abstract
This study provides a systematic review and meta-analysis of randomized controlled trials, which have examined the effect of the carnitine on adult weight loss. Relevant studies were identified by systematic search of PubMed, Embase, Cochrane Central Register of Controlled Trials and reference lists of relevant marker studies. Nine studies (total n = 911) of adequate methodological quality were included in the review. Trials with mean difference (MD) of 95% confidence interval (CI) were pooled using random effect model. Results from meta-analysis of eligible trials revealed that subjects who received carnitine lost significantly more weight (MD: -1.33 kg; 95% CI: -2.09 to -0.57) and showed a decrease in body mass index (MD: -0.47 kg m(-2) ; 95% CI: -0.88 to -0.05) compared with the control group. The results of meta-regression analysis of duration of consumption revealed that the magnitude of weight loss resulted by carnitine supplementation significantly decreased over time (p = 0.002). We conclude that receiving the carnitine resulted in weight loss. Using multiple-treatments meta-analysis of the drugs and non-pharmacotherapy options seem to be insightful areas for research. © 2016 World Obesity.
L-carnitine promotes liver regeneration after hepatectomy by enhancing lipid metabolism
Abstract
Background: Lipid metabolism plays an important role in liver regeneration, but its regulation still requires further research. In this study, lipid metabolites involved in mouse liver regeneration at different time points were sequenced and analyzed to study their influence on liver regeneration and its mechanism.
Methods: Our experiment was divided into two parts. The first part examined lipid metabolites during liver regeneration in mice. In this part, lipid metabolites were sequentially analyzed in the livers of 70% mouse hepatectomy models at 0, 1, 3and 7 days after operation to find the changes of lipid metabolites in the process of liver regeneration. We screened L-carnitine as our research object through metabolite detection. Therefore, in the second part, we analyzed the effects of carnitine on mouse liver regeneration and lipid metabolism during liver regeneration. We divided the mouse into four groups: control group (70% hepatectomy group); L-carnitine group (before operation) (L-carnitine were given before operation); L-carnitine group (after operation)(L-carnitine were given after operation) and L-carnitine + perhexiline maleate (before operation) group. Weighing was performed at 24 h, 36 and 48 h in each group, and oil red staining, HE staining and MPO staining were performed. Tunnel fluorescence staining, Ki67 staining and serological examination.
Results: Sequencing analysis of lipid metabolites in 70% of mouse livers at different time points after hepatectomy showed significant changes in carnitine metabolites. The results showed that, compared with the control group the mouse in L-carnitine group (before operation) at 3 time points, the number of fat drops in oil red staining was decreased, the number of Ki67 positive cells was increased, the number of MPO positive cells was decreased, the number of Tunnel fluorescence positive cells was decreased, and the liver weight was increased. Serum enzymes were decreased. Compared with control group, L-carnitine group (after operation) showed similar trends in all indexes at 36 and 48 h as L-carnitine group (before operation). L-carnitine + perhexiline maleate (before operation) group compared with control group, the number of fat drops increased, the number of Ki67 positive cells decreased, and the number of MPO positive cells increased at 3 time points. The number of Tunnel fluorescent positive cells increased and serum enzyme increased. However, both liver weights increased.
Conclusion: L-carnitine can promote liver cell regeneration by promoting lipid metabolism and reduce aseptic inflammation caused by excessive lipid accumulation.
