The effect of alpha-lipoic acid supplementation on anthropometric, glycemic, lipid, oxidative stress, and hormonal parameters in individuals with polycystic ovary syndrome: a systematic review and meta-analysis of randomized clinical trials. Obstet Gynecol Sci 2024; 67:17-29.

Abstract
This systematic review and meta-analysis aimed to examine the effect of the antioxidant alpha-lipoic acid (ALA) on various cardiometabolic risk factors and hormonal parameters in patients with polycystic ovary syndrome (PCOS). We searched PubMed, EMBASE, SCOPUS, Cochrane Library, and Web of Science databases without language restrictions until May 2023 to find randomized controlled trials (RCTs) that assessed the impact of ALA supplementation on anthropometric, glycemic, lipid, oxidative stress, and hormonal parameters in women with PCOS. Outcomes were summarized using the standardized mean difference (SMD) and 95% confidence interval (CI) in a random-effects model. An I2 statistic of >60% established significant between-study heterogeneity. The overall certainty of the evidence for each outcome was determined using the grading of recommendations, assessment, development, and evaluations system. Seven RCTs met the inclusion criteria. The ALA group had significant reductions in fasting blood sugar (fasting blood sugar (FBS), n=7 RCTs, SMD, -0.60; 95% CI, -1.10 to -0.10; I2=63.54%, moderate certainty of evidence) and homeostatic model assessment for insulin resistance (homeostatic model assessment of insulin resistance (HOMA-IR), n=4 RCTs, SMD, -2.03; 95% CI, -3.85 to -0.20; I2=96.32%, low certainty of evidence) compared with the control group. However, significant differences were observed between the groups in body mass index, insulin, estrogen, follicle-stimulating hormone, luteinizing hormone, testosterone, low-density lipoprotein, highdensity lipoprotein, triglyceride, total cholesterol, malondialdehyde, or total antioxidant capacity profiles. ALA supplementation improves FBS and HOMA-IR levels in women with PCOS. ALA consumption is an effective complementary therapy for the management of women with PCOS.

Curr Neuropharmacol 2024; 22:53-64. [PMID: 37550909 DOI: 10.2174/1570159x21666230807103642] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Revised: 02/17/2023] [Accepted: 03/15/2023] [Indexed: 08/09/2023] Open
Abstract
A majority of older patients suffer from neuropathic pain (NP) that significantly alters their daily activities and imposes a significant burden on health care. Multiple comorbidities and the risk of polypharmacy in the elderly make it challenging to determine the appropriate drug, dosage, and maintenance of therapy. Age-dependent processes play a contributing role in neuropathy given that diabetic neuropathy (DN) is the most common form of neuropathy. This narrative review is mainly focused on the drug treatment approach for neuropathy-associated pain in aged people including both drugs and dietary supplements, considering the latter as add-on mechanism-based treatments to increase the effectiveness of usual treatments by implementing their activity or activating other analgesic pathways. On one hand, the limited clinical studies assessing the effectiveness and the adverse effects of existing pain management options in this age segment of the population (> 65), on the other hand, the expanding global demographics of the elderly contribute to building up an unresolved pain management problem that needs the attention of healthcare providers, researchers, and health authorities as well as the expansion of the current therapeutic options.

Exploring the effectiveness of vitamin B 12 complex and alpha-lipoic acid as a treatment for diabetes mellitus/neuropathy: a protocol for systematic review and meta-analysis of randomised controlled trials. BMJ Open 2022; 12:e065630.

Abstract
INTRODUCTION Diabetic neuropathy (DN) is common in patients diagnosed with diabetes mellitus. This often causes peripheral nerve damage. For many years vitamin B12 and alpha-lipoic acid (ALA) have been regarded as components that can be used in reducing markers of inflammation and oxidative stress. In this study, we will explore the effectiveness of vitamin B12 and ALA as a possible treatment for diabetic mellitus/neuropathy, emphasising markers of inflammation, lipid profile, and glucose metabolism. METHODS AND ANALYSIS We will conduct a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol (PRISMA-P). The search strategies and information sources for the literature will be PubMed, Google Scholar, Web of Science and Science direct. The literature search will include studies published from inception until 30 June 2022. All included studies will be evaluated for quality and risk of bias according to the Cochrane guidelines. To investigate the stability of the results, we will conduct a sensitivity analysis of the outcomes. All data analysis will be performed using Review Manager V.5. 4. ETHICAL AND DISSEMINATION This systematic review and meta-analysis will not require ethical approval from an institution committee as it does not have direct participants. We will obtain all our data from previous studies. The findings will be disseminated through publications in peer-reviewed journals and presented at local and international seminars and conferences.
