Frye RE, Rincon N, McCarty PJ, Brister D, Scheck AC, Rossignol DA · Neurobiology of disease · 2024

Autism spectrum disorder (ASD) is a neurodevelopmental disorder affecting 1 in 36 children and is associated with physiological abnormalities, most notably mitochondrial dysfunction, at least in a subset of individuals. This systematic review and meta-analysis discovered 204 relevant articles which evaluated biomarkers of mitochondrial dysfunction in ASD individuals. Significant elevations (all p < 0.01) in the prevalence of lactate (17%), pyruvate (41%), alanine (15%) and creatine kinase (9%) were found in ASD. Individuals with ASD had significant differences (all p < 0.01) with moderate to large effect sizes (Cohen's d' ≥ 0.6) compared to controls in mean pyruvate, lactate-to-pyruvate ratio, ATP, and creatine kinase. Some studies found abnormal TCA cycle metabolites associated with ASD. Thirteen controlled studies reported mitochondrial DNA (mtDNA) deletions or variations in the ASD group in blood, peripheral blood mononuclear cells, lymphoc

Ashton MM, Kavanagh BE, Marx W, Berk M, Sarris J, Ng CH · Canadian journal of psychiatry. Revue canadienne de psychiatrie · 2021

Certain nutrient supplements (nutraceuticals) may target neurobiological pathways perturbed in bipolar disorder (BD) such as inflammation, oxidative stress, and mitochondrial dysfunction. Nutraceuticals thus may have a potential role as adjunctive treatments for BD. A search of Embase via embase.com, PubMed via PubMed, Cumulated index to nursing and allied health literature (CINAHL) Complete via EBSCO, and Cochrane Central Register of Controlled Clinical Trials via cochranelibrary.com was conducted to identify published randomized controlled trials assessing the efficacy of nutraceuticals on mood symptomatology in adults with BD. Search terms for BD, nutraceuticals, and clinical trials (total search terms = 75) were used to search from inception to February 20, 2020. The Cochrane Collaboration's tool for assessing the risk of bias in randomized trials was used to assess the risk of bias. A total of 1,712 studies were identified through the search. After rigorous screening, 22 studies

Persico AM, Asta L, Chehbani F, Mirabelli S, Parlatini V, Cortese S · Progress in neuro-psychopharmacology & biological psychiatry · 2025

Part I of this systematic review summarized the state-of-the-art of pediatric psychopharmacology for Autism Spectrum Disorder (ASD), a severe and lifelong neurodevelopmental disorder. The purpose of this Part II follow-up article is to provide a systematic overview of the experimental psychopharmacology of ASD. To this aim, we have first identified in the Clinicaltrials.gov website all the 157 pharmacological and nutraceutical compounds which have been experimentally tested in children and adolescents with ASD using the randomized placebo-controlled trial (RCT) design. After excluding 24 drugs already presented in Part I, a systematic review spanning each of the remaining 133 compounds was registered on Prospero (ID: CRD42023476555), performed on PubMed (August 8, 2024), and completed with EBSCO, PsycINFO (psychology and psychiatry literature) and the Cochrane Database of Systematic reviews, yielding a total of 115 published RCTs, including 57 trials for 23 pharmacological compounds an

Salekzamani S, Pakkhesal S, Babaei M, Mirzaaghazadeh E, Mosaddeghi-Heris R, Talebi M · Multiple sclerosis and related disorders · 2025 · n=195

Multiple Sclerosis (MS) is a chronic and progressive inflammatory disease of the central nervous system (CNS). Oxidative stress is a crucial mediator in multiple conditions, including the MS. Coenzyme Q10 (CoQ10) is a potent antioxidant, present in enzyme complexes of mitochondria, and involved in oxidative phosphorylation to produce adenosine triphosphate (ATP). The objective of this systematic review was to investigate the outcomes of CoQ10 supplementation in oxidative stress, inflammatory, and clinical status of patients with MS. Following the Cochrane and PRISMA methods, a comprehensive search was conducted in PubMed, Scopus, Embase, and Web of Science databases, and clinical studies that reported the outcomes of CoQ10 supplementation in MS patients, are included. The risk of bias was assessed using the revised Cochrane risk-of-bias tool for randomized trials (RoB2). The initial search yielded 237 articles, of which eight reports from six studies (total n = 195), including three

Freire de Carvalho J, Skare T · Clinical nutrition ESPEN · 2024 · n=483

Coenzyme Q10 (CoQ10) is a potent antioxidant and anti-inflammatory substance used to treat some rheumatic diseases. Our objective was to review the use of CoQ10 in rheumatic diseases. PubMed/Medline, Embase, Scopus, and Web of Science databases were searched for articles on CoQ10 and rheumatic diseases between 1966 and April 2023. Twenty articles were found, including 483 patients. The investigated conditions were Fibromyalgia (FM) with 15 studies, Rheumatoid Arthritis (RA) with 3 studies, and Antiphospholipid Syndrome (APS) with 2 studies. After CoQ10 supplementation, RA patients observed improvements in disease activity index, inflammatory biomarkers (erythrocyte sedimentation rate), cytokine levels, and a decrease in malondialdehyde. In APS, CoQ10 improved endothelial function and decreased prothrombotic and proinflammatory mediators. Regarding FM, in most of the studies, the patients observed improvements in pain, fatigue, sleep, tender points count, mood disorders, and scores on t

The increasing recognition of cyclic vomiting syndrome (CVS) in adults prompted the development of these evidence-based guidelines on the management of CVS in adults, which was sponsored by the American Neurogastroenterology and Motility Society (ANMS) and the Cyclic Vomiting Syndrome Association (CVSA). GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) framework was used and a professional librarian performed the literature search. The expert committee included the President of the CVSA who brought a patient perspective into the deliberations. The committee makes recommendations for the prophylaxis of CVS, treatment of acute attacks, diagnosis, and overall management of CVS. The committee strongly  recommends that adults with moderate-to-severe CVS receive a tricyclic antidepressant (TCA), such as amitriptyline, as a first-line prophylactic medication and receive topiramate or aprepitant as alternate prophylactic medications. Zonisamide or levetiracetam

Norouzi M, Mahboobi S, Eftekhari MH, Salehipour M, Ghaem H, Mirzakhanlouei A · Nutrition and cancer · 2024

The prevalence of benign prostatic hyperplasia (BPH) and its associated lower urinary tract symptoms (LUTS) increases with age. Considering that BPH drug treatment is associated with complications, this study aimed to investigate the effects of L-carnitine (LC) and Coenzyme Q10 (CoQ10) supplementation as an adjunct therapy to finasteride in the management of LUTS in older men affected with BPH. Fifty eligible volunteers (25 per group) were randomly assigned to either intervention (finasteride + LC and CoQ10 supplements) or control (finasteride + placebo) groups. International prostate symptom score (IPSS), international index of erectile function (IIEF), quality of life index (QoL), as well as serum levels of Prostate-specific antigen (PSA), were assessed. Prostate ultrasound evaluation was also performed, before and after 8 wk of intervention. Supplementation with LC and CoQ10 led to a significant decrease in prostate volume (p < 0.001) as

Effect of Dietary Coenzyme Q10 Plus NADH Supplementation on Fatigue Perception and Health-Related Quality of Life in Individuals with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Prospective, Randomized, Double-Blind, Placebo-Controlled Trial.

Castro-Marrero J, Segundo MJ, Lacasa M, Martinez-Martinez A, Sentañes RS, Alegre-Martin J · Nutrients · 2021 · n=104

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex, multisystem, and profoundly debilitating neuroimmune disease, probably of post-viral multifactorial etiology. Unfortunately, no accurate diagnostic or laboratory tests have been established, nor are any universally effective approved drugs currently available for its treatment. This study aimed to examine whether oral coenzyme Q10 and NADH (reduced form of nicotinamide adenine dinucleotide) co-supplementation could improve perceived fatigue, unrefreshing sleep, and health-related quality of life in ME/CFS patients. A 12-week prospective, randomized, double-blind, placebo-controlled trial was conducted in 207 patients with ME/CFS, who were randomly allocated to one of two groups to receive either 200 mg of CoQ10 and 20 mg of NADH (n = 104) or matching placebo (n = 103) once daily. Endpoints were simultaneously evaluated at baseline, and then reassessed at 4- and 8-week treatment visits and four weeks after treatme

Adams JB, Audhya T, Geis E, Gehn E, Fimbres V, Pollard EL · Nutrients · 2018

This study involved a randomized, controlled, single-blind 12-month treatment study of a comprehensive nutritional and dietary intervention. Participants were 67 children and adults with autism spectrum disorder (ASD) ages 3-58 years from Arizona and 50 non-sibling neurotypical controls of similar age and gender. Treatment began with a special vitamin/mineral supplement, and additional treatments were added sequentially, including essential fatty acids, Epsom salt baths, carnitine, digestive enzymes, and a healthy gluten-free, casein-free, soy-free (HGCSF) diet. There was a significant improvement in nonverbal intellectual ability in the treatment group compared to the non-treatment group (+6.7 ± 11 IQ points vs. -0.6 ± 11 IQ points, p = 0.009) based on a blinded clinical assessment. Based on semi-blinded assessment, the treatment group, compared to the non-treatment group, had significantly greater improvement in autism symptoms and developmental age. The treatment group had

Dietary supplements and prevention of preeclampsia.

Ushida T, Tano S, Matsuo S, Fuma K, Imai K, Kajiyama H · Hypertension research : official journal of the Japanese Society of Hypertension · 2025

Preeclampsia (PE) is a common pregnancy complication characterized by hypertension, proteinuria, and end-organ dysfunction. However, to date, no effective treatment has been established other than iatrogenic delivery, and the importance of prevention as an alternative approach to addressing PE has been emphasized. There is growing evidence on the effectiveness of pharmacological and non-pharmacological prophylaxis in preventing PE. In this review, we focused on dietary supplements as non-pharmacological prophylaxis for PE. Calcium is a well-documented supplement for the prevention of PE. Daily 500 mg calcium supplementation can roughly halve the risk of PE in settings where calcium intake is low, including in Japan. According to recent systematic reviews and network meta-analyses, current evidence on the efficacy of vitamin D supplementation is inconsistent. Although vitamin D is a candidate for the prevention of PE, future large-scale randomized control trials are necessary to

Practical supplements for prevention and management of migraine attacks: a narrative review.

Hajhashemy Z, Golpour-Hamedani S, Eshaghian N, Sadeghi O, Khorvash F, Askari G · Frontiers in nutrition · 2024

Migraine is one of the most debilitating neurological disorders that causes frequent attacks of headaches and affects approximately 11% of the global population. Deficient or even insufficient levels of vital nutrients would increase the severity and frequency of migraine attacks. Therefore, we aimed to examine the practical supplements for the prevention and management of migraine attacks. This narrative review study was conducted by searching PubMed, ISI web of science, EMBASE, Google Scholar, and Scopus using the keywords of "dietary supplement" and "migraine" plus their MeSH terms. Original articles published in English language from their inception to July 27th, 2024, studies that investigated adult population (aged >18 years), and those assessing the impact of intended nutrient supplementation on clinical symptoms of migraine were included in the study. Oxidative stress and low intake of antioxidants would be risk factors for migraine attacks by inducing inflammation.
