Phase II/III multicenter, randomized, double-blind, placebo-controlled trial on acetyl-L-carnitine (ALCAR) in subjects living with amyotrophic lateral sclerosis (ALS). Primary study aim: The clinical objective consists of assessing the efficacy of ALCAR (two different dosages will be tested: 1.5g/day and 3g/day) on the progression of functional disability (loss of self-sufficiency), as measured by the ALSFRS-R scale. Secondary study aims: 1. The effect of ALCAR treatment on different clinical aspects: functional decline as measured by ALSFRS-R total score; the decline of forced vital capacity (FVC); quality of life as measured by ALSAQ-40 scale; cognitive function as measured by Edinburgh Cognitive and Behavioural ALS Screen (ECAS) scale; survival (being alive and without tracheostomy). 2. To measure the effects of ALCAR treatment on disease biomarkers potentially involved in the drug's mechanisms of action. These include PGC-1 alpha, 3-nitrotyrosine (3-NT), acetyl cyclophilin A (acetyl-PPIA), neurofilament light chain (NFL), creatine kinase (CK), Musclin/osteocrin, MyomiRNA (MiR-206), Uric acid, Matrix metalloproteinase-9 (MMP-9), Monocyte Chemoattractant Protein-1 (MCP-1), 4-Hydroxynonenal (HNE). 3. The tolerability and safety of ALCAR treatment by identifying unexpected adverse events.
Study population: 246 subjects will be enrolled on one Australian and ten Italian ALS sites.
Inclusion criteria: subjects aged 18+ years with a diagnosis of ALS according to Gold Coast Criteria; disease duration <24 months; satisfactory bulbar and spinal function (self-sufficiency evaluated by a score 3+ on the ALSFRS-R for swallowing, cutting food and handling utensils, and walking); satisfactory respiratory function (FVC ≥80% of predicted); documented progression of symptoms as measured by the ALSFRS-R scale. Disease progression rate (DFS) must be>= 0.33. DFS =(48- ALSFRS-R at screening)/months from onset to screening, treatment with Riluzole in the last four weeks. Exclusion criteria: antecedent polio infection; other motor neuron disease; involvement of other systems possibly determining a functional impairment; other severe clinical conditions; unwillingness or inability to take riluzole; previous use of ALCAR for any reason; inability to understand and comply with the study requirements, and to give written informed consent personally or via their legally authorized representative.
All eligible participants will be randomized to receive ALCAR (1,5 or 3 g/day) or placebo in addition to riluzole 50 mg b.i.d. Permuted block (with a block size of 6), 1:1:1 centralized randomization scheme will be used. The overall treatment duration will be 48 weeks. After enrolment, each participant will be followed up until death. Eligible subjects will be seen after 4, 12, 24, 36 and 48 weeks. At each visit, a general assessment will be made, including vital signs, body mass index (BMI), neurological examination (including quantitative and qualitative evaluation of the motor system), comorbidity, concomitant treatments and adverse events. Blood samples will be collected at baseline -Day 1 (randomization)-, 4, 12, 24, 36 and 48 weeks to test biomarkers. Functional disability will be assessed at each visit using the ALS-FRS-R scale. The respiratory function will be assessed using a spirometer to measure FVC before starting treatment (baseline visit) and at 4, 12, 24, 36 and 48 weeks. Cognitive function will be evaluated at baseline, weeks 24 and 48, using ECAS scale. Health-related quality of life, measured by the ALSAQ-40, will be tested at baseline, 24 and 48 weeks. Compliance will be tested by the local investigators, counting unused packages at each follow-up visit. Pre-planned statistical analyses will be done on Intention-to-treat and Per-protocol (PP) populations. The statistical plan will include descriptive statistics and a comparison of the proportions of self-sufficient participants at week 48 using the chi-square or Fisher's exact test for the primary endpoint. Secondary endpoints measured by numerical scores obtained from clinical scales will be analyzed using repeated measures mixed models, while biomarkers using repeated measures ANOVA. Time-to-event endpoints, such as survival and the probability of remaining self-sufficient over 48 weeks, will be analyzed with Kaplan-Meier curves. The number of adverse events and serious adverse events after 48 weeks will be compared between treatment arms.

Revealing degradation pathways of soluble and dissolved organic matter in alluvial-lacustrine aquifer systems impacted by high levels of geogenic ammonium

Article

作者: Gan, Yiqun ; Xiong, Yaojin ; Liu, Meihui ; Du, Yao ; Shi, Huanhuan ; Deng, Yamin ; Wang, Yanxin

The excessive presence of geogenic ammonium (NH₄⁺) in groundwater poses a global environmental concern, commonly linked to the degradation of nitrogen-containing dissolved organic matter (DOM). However, there is a gap in systematic studies on the combination of soluble organic matter (SOM) in sediments and DOM in groundwater, with few indoor incubation experiments to validate their degradation pathways. This study utilized ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry to analyze the molecular characteristics of DOM and SOM in aquifer systems affected by geogenic NH₄⁺. Subsequently, indoor incubation experiments spanning up to 140 d were conducted to verify the degradation pathways. The experimental results revealed a two-phase degradation process for both the DOM and SOM. The initial stage was characterized by the degradation of aliphatic compounds (ALC) with the production of polyphenols (PPE) and highly unsaturated compounds (HUC). The second stage was dominated by the degradation of PPE and HUC, accompanied by the re-consumption of some ALC, while more recalcitrant HUC persisted. Notably, the first stage of SOM degradation exceeded that of DOM degradation, indicating that SOM exhibited greater resistance to aging. This phenomenon may be attributed to a wider range of active enzymes in sediments, the rapid replenishment of SOM by organic matter in sediments, or the accelerated degradation of DOM. The experimental results aligned with the molecular characterization of DOM and SOM in actual aquifer systems. It is hypothesized that NH₄⁺ produced through the direct mineralization of SOM may contribute more to the enrichment of NH₄⁺ in groundwater than that produced through the mineralization of DOM. This study is the first to analyze DOM and SOM together in aquifer systems and validate their degradation pathways through incubation experiments, thereby providing novel insights into the enrichment of geogenic NH₄⁺ in groundwater.

Neuronutritional Approach to Fibromyalgia Management: A Narrative Review

Review

作者: Danilov, Andrey ; Danilov, Alexey ; Badaeva, Anastasiia ; Vorobyeva, Yulia ; Novikov, Viacheslav ; Lepshina, Mariia ; Kosareva, Anastasiia

Fibromyalgia (FM) is a complex and common syndrome characterized by chronic widespread pain, fatigue, sleep disturbances, and various functional symptoms without clear structural or pathological causes. Affecting approximately 1-5% of the global population, with a higher prevalence in women, FM significantly impacts patients' quality of life, often leading to considerable healthcare costs and loss of productivity. Despite its prevalence, the etiology of FM remains elusive, with genetic, environmental, and psychological factors, including nutrition, being implicated. Currently, no universally accepted treatment guidelines exist, and management strategies are often symptomatic. This narrative review explores the potential of a neuronutritional approach to FM management. It synthesizes existing research on the relationship between FM and nutrition, suggesting that dietary interventions could be a promising complementary treatment strategy. Various nutritional interventions, including vitamin D, magnesium, iron, and probiotics supplementation, have shown potential in reducing FM symptoms, such as chronic pain, anxiety, depression, cognitive dysfunction, sleep disturbances, and gastrointestinal issues. Additionally, weight loss has been associated with reduced inflammation and improved quality of life in FM patients. The review highlights the anti-inflammatory benefits of plant-based diets and the low-FODMAPs diet, which have shown promise in managing FM symptoms and related gastrointestinal disorders. Supplements such as vitamin D, magnesium, vitamin B12, coenzyme Q10, probiotics, omega-3 fatty acids, melatonin, S-adenosylmethionine, and acetyl-L-carnitine are discussed for their potential benefits in FM management through various mechanisms, including anti-inflammatory effects, modulation of neurotransmitters, and improvement of mitochondrial function. In conclusion, this review underscores the importance of considering neuronutrition as a holistic approach to FM treatment, advocating for further research and clinical trials to establish comprehensive dietary guidelines and to optimize management strategies for FM patients.

世界肝炎日，关注药物性肝损伤

7月28日是“世界肝炎日”，今年的宣传主题是“消除肝炎，积极行动”。近年来，我国病毒性肝炎发病率呈下降趋势，但非病毒性肝炎发病率明显升高，主要包括脂肪型肝炎、酒精性肝炎、药物性肝损伤（DILI）等。其中，药物性肝损伤是当前急性肝损伤最为常见的病因之一，正成为全球急性肝衰竭的主要病因，其占比正在逐渐增加。根据2014年发布的国内迄今最大规模的药物性肝损伤流行病学研究成果——《中国大陆药物性肝损伤发生率及病因学》显示，我国药物性肝损伤的年发病率为23.8/10万人，远高于法国、美国、西班牙、瑞士等欧美国家，其中急性药物性肝损伤占87%。目前已知全球有超出1100种上市药物具有潜在肝毒性。在欧美国家，非甾体抗炎药、抗感染药物是引起药物性肝损伤的常见药物。在我国，传统中草药和膳食补充剂、抗结核药、抗肿瘤药、免疫调节剂是引起肝损伤的主要可疑药物。在亚洲，传统治疗药物具有悠久的应用历史并广泛用于各类疾病的预防和治疗。由于很多患者存在草药“天然无毒”的错误认识，对草药的肝损伤风险常缺乏警惕，我国多数研究报道的 DILI 患者由草药引起占比约为 20% ～ 30% 。在我国，据报道可能引起肝损伤的有何首乌、雷公藤、黄药子、补骨脂、千里光、淫羊藿、菊三七等 HMs 及其汤剂或成药。 1、根据发病机制，DILI 分为固有型、特异质型和间接型： 2、根据生物化学异常模式，DILI分为肝细胞损伤型、胆汁淤积型和混合型：（1）肝细胞损伤型：R ≥ 5；轻者可无任何症状；重者则可出现黄疸，如全身皮肤和 / 或巩膜黄染、尿色加深等，伴或不伴不同程度的乏力、食欲减退、厌油、肝区胀痛及上腹不适等非特异性消化道症状。（2）胆汁淤积型：R ≤ 2；明显者可出现黄疸、大便颜色变浅和瘙痒等表现。进展为 ALF/SALF 者则可出现黄疸、凝血功能障碍、腹水、肝性脑病等相关症状。（3）混合型：2 ＜ R ＜ 5。 R 值＝ [ 丙氨酸转氨酶（ALT）实测值 /ALT 的正常值上限（ULN）] / [ 碱性磷酸酶（ALP）实测值/ALP的ULN]。ALT缺失时，可用天冬氨酸转氨酶（AST）取代进行计算。 R值计算通常是基于首次可获得的异常肝脏生物化学检查结果，可大致反映肝损伤时的生物化学异常模式。发病起始时的 R 值可随着肝损伤的演变而发生变化，病程中动态监测 R 值，有助于更全面地了解和判断肝损伤的演变过程。 3、特殊表型 7% ～ 13% 的患者在急性 DILI 事件后的 6 个月或 1 年，肝脏生物化学指标仍未恢复至正常或基线水平，提示急性肝损伤可能转化为慢性或肝损伤延迟恢复。 1、病史采集：详细、完整的包括可疑药物应用史在内的病史采集对评估因果关系，最终建立 DILI 诊断至关重要。疑似 DILI 患者，建立诊断或进行因果关系评估至少需采集的病史信息包括：（1）可疑药物信息及开始和停止用药时间；（2）可疑药物和/或同类药物的既往暴露史及反应；（3）其他合并用药信息及反应；（4）疑似 DILI 事件的起病时间、预后、去激发的反应等；（5）伴随疾病和基础肝病或既往肝损伤史；（6）排除肝损伤其他病因。 2、实验室检查：诊断急性 DILI 时肝脏生物化学阈值需达到下述标准之一：（1）ALT ≥ 5×ULN ；（2）ALP ≥ 2×ULN（尤其是伴随 GGT 升高且排除骨骼疾病引起的 ALP 水平升高）；（3）ALT ≥ 3×ULN 同时 TBil ≥ 2×ULN。未达上述阈值标准而因果关系评估为药物引起者，可界定为药物性肝脏生物化学异常。需提醒的是，上述肝脏生物化学阈值标准仅适用于急性 DILI 时的诊断，不适用于慢性和特殊表型 DILI 的临床诊断。 3、组织学检查 DILI 的组织学表现复杂多样，几乎涵盖了肝脏病理改变的全部范畴。由于缺乏特异性的诊断生物标志物，DILI 的诊断目前仍是基于详细病史采集、临床症状和体征、血清生物化学、影像学和组织学等的排他性策略。根据药品不良反应 / 事件关联性评价的原则，建立诊断最终很大程度上依赖于：（1）药物暴露或停药与肝脏生物化学的改变有明确、合理的时效关系；（2）肝损伤的临床和/或病理表现（型）与可疑药物已知的肝毒性一致；（3）停药或减少剂量后肝损伤显著改善或恢复正常；（4）再次用药后肝损伤再次出现；（5）排除了肝损伤的其他病因和基础肝病的活动或复发，且无法用其他合并用药/治疗手段、原发疾病进展来解释。急性 DILI 诊断建立后，需对其严重程度进行评估，可按以下国际 DILI 专家工作组标准： 1级（轻度）：ALT ≥ 5×ULN 或 ALP ≥ 2×ULN 且 TBil ＜ 2×ULN； 2级（中度）：ALT ≥ 5×ULN 或 ALP ≥ 2×ULN 且 TBil ≥ 2×ULN，或有症状性肝炎； 3级（重度）：ALT ≥ 5×ULN 或 ALP ≥ 2×ULN 且 TBil ≥ 2×ULN，或有症状性肝炎并达到下述任何 1 项： ①INR ≥ 1.5， ②腹水和/或肝性脑病，病程 < 26 周，且无肝硬化， ③DILI 导致的其他器官功能衰竭； 4级（致命）：因 DILI 死亡，或需接受肝移植才能生存。除了及时停用可疑肝损伤药物，尽量避免再次使用可疑或同类药物外，还可以结合目前循证医学证据，合理选择治疗药物。除了上述比较常用的药物外，临床可以根据患者的具体情况酌情使用多烯磷脂酰胆碱、熊去氧胆酸、腺苷蛋氨酸、左旋肉碱和谷胱甘肽等。 1、鹅膏毒素引起的 DILI——水飞蓟素（宾）类多项临床研究证实水飞蓟素（宾）类能够有效治疗鹅膏毒素中毒所致肝损伤。一项收集20年2000例毒蕈导致肝损伤患者的回顾性研究发现，应用水飞蓟素（宾）类的病死率为5.8%，而未使用水飞蓟素（宾）类的病死率高达14.1%。此外，还有临床研究证实水飞蓟素（宾）类治疗毒蕈中毒时安全性良好，可用于中位数年龄为5岁的儿童患者。 2、胆汁淤积型DILI——熊去氧胆酸/S-腺苷蛋氨酸：胆汁淤积型DILI患者，尤其是严重或恢复缓慢的胆汁淤积型或混合型DILI患者中可使用熊去氧胆酸或S-腺苷蛋氨酸，用以降低ALP水平。 3、对乙酰氨基酚（APAP）引起的固有型DILI——N-乙酰半胱氨酸（NAC）： NAC是被FDA批准用来治疗APAP引起的固有型DILI的唯一解毒药物。 4、急性DILI——异甘草酸镁：异甘草酸镁是目前唯一具有急性DILI适应证的药物。 5、DRESS综合征、DI-ALH、ICIs肝毒性——糖皮质激素：对于伴随超敏或自身免疫征象的免疫介导的DILI是糖皮质激素应用的指征，如DRESS综合征、DI-ALH、ICIs肝毒性。参考文献： [1]中国医药生物技术协会药物性肝损伤防治技术专业委员会, 中华医学会肝病学分会药物性肝病学组. 中国药物性肝损伤诊治指南（2023 年版）[J]. 中华肝脏病杂志,2023,31(4):355-384.
