curcumin and Fatigue

Xanthorrhizol (XTZ), a bisabolene sesquiterpenoid, is abundantly found in the plant Curcuma xanthorrhiza Roxb. Traditionally, C. xanthorrhiza is widely used for the treatment of different health conditions, including common fever, infection, lack of appetite, fatigue, liver complaints, and gastrointestinal disorders. XTZ exhibits wide-ranging pharmacological activities, including anticancer, antioxidative, anti-inflammatory, antimicrobial, and antidiabetic activities, in addition to a protective effect on multiple organs. The present review provides detailed findings on the anticancer activities of XTZ and the underlying cellular and molecular mechanisms.. Literature was searched systematically in main databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, with keywords "tumor AND xanthorrhizol" or "cancer AND xanthorrhizol".. Studies show that XTZ has preventive and therapeutic activities against different types of cancer, including breast, cervical, colon, liver, lung, oral and esophageal, and skin cancers. XTZ regulates multiple signaling pathways that block carcinogenesis and proliferation. In vitro and in vivo studies showed that XTZ targets different kinases, inflammatory cytokines, apoptosis proteins, and transcription factors, leading to the suppression of angiogenesis, metastasis, and the activation of apoptosis and cell cycle arrest.. The potential anticancer benefits of XTZ recommend further in vivo studies against different types of cancer. Further, XTZ needs to be confirmed for its toxicity, bioavailability, protective, antifatigue, and energy booster activities. Future studies for the therapeutic development of XTZ may be directed to cancer-related fatigue.

Curcumin (a flavonoid isolated from turmeric) affects several processes involved in neurocognitive aging. We have previously reported that short term (4-weeks) administration of a highly bioavailable curcumin preparation (Longvida©) improved working memory and reduced fatigue and stress reactivity in a healthy older cohort. The present trial (ACTRN12616000484448) was a partial replication study, evaluating similar effects at 4 and 12-weeks Longvida© supplementation. A double-blind, placebo-controlled, parallel-groups trial was conducted. Eighty participants aged 50-80 years (mean = 68.1, SD = 6.34) were randomised to receive Longvida© (400 mg daily containing 80 mg curcumin) or a matching placebo. Assessment took place at baseline then following 4 and 12 weeks treatment. Outcome measures included cognitive performance, mood and biomarkers. Compared with placebo, curcumin was associated with several significant effects. These included better working memory performance at 12-weeks (Serial Threes, Serial Sevens and performance on a virtual Morris Water Maze), and lower fatigue scores on the Profile of Mood States (POMS) at both 4 and 12-weeks, and of tension, anger, confusion and total mood disturbance at 4-weeks only. The curcumin group had significantly elevated blood glucose. These results confirm that Longvida© improves aspects of mood and working memory in a healthy older cohort. The pattern of results is consistent with improvements in hippocampal function and may hold promise for alleviating cognitive decline in some populations.

Better patient-reported outcomes (PROs) of laparoscopic cholecystectomy (LC) are premised upon PROs such as postoperative pain and fatigue. These PROs are indices of convalescence and return to normal activity. Curcumin (turmeric) is used in India for traumatic pain and fatigue for its anti-inflammatory/antioxidant and tissue modulation/healing properties. We studied the effect of curcumin on pain and postoperative fatigue in patients of LC.. From July to September 2009, 50 consecutive day-care LC candidates were enrolled for a prospective, double-blind randomized placebo-controlled study. A uniform general anesthesia and analgesia protocol was followed. Curcumin/placebo and rescue analgesic were prescribed at discharge. Patients were told to maintain pain/fatigue/adverse event diaries based upon 100-point visual analog pain scale (VAS) and 10-point interval rating fatigue scale (IRS). Patients were followed up at third day (D3), first week (W1), second week (W2), and third week (W3). The blind labels were opened at the end of study.. Demographic characteristics, comorbidity, and gallbladder pathology profiles were comparable in the study (n = 25) and control groups (n = 25). There was no adverse surgical outcome, adverse PRO or withdrawal. Pain and fatigue scores at D3 were similar in the two groups. At W1 and W2, the study group showed significantly lower (p value 0.000) mean pain scores, i.e., 15 ± 5.204 versus 30 ± 13 in controls. Fatigue scores at W1, W2, and W3 were significantly lower (p value 0.000) in the study group, i.e., 2.16 ± 1.748, 1, and 0, respectively, versus 5.16 ± 1.375, 4.20 ± 1.633, and 1 in controls. All patients were pain free at W3. Analgesic tablet usage was significantly lower (p value 0.000) in the study group, i.e., 6.96 ± 1.837 versus 39.32 ± 16.509 in controls.. Turmeric (curcumin) improves postoperative pain- and fatigue-related PROs following LC.

In a previous study, we evaluated the potential beneficial effect of nano-bubble curcumin extract (NCE) in reducing exercise-related injuries and improving performance.. In this study, we seek to investigate changes in the gut microbiota composition upon NCE supplementation in relation to health and exercise performance. Male ICR mice were divided into 3 groups (n = 8 per group) and orally administered NCE once daily for six weeks at 0 (vehicle), 3.075 (NCE-1X) and 15.375 g kg. NCE-5X did not appear to obviously cluster with the vehicle group, although NCE-5X groups showed an increased Firmicutes/Bacteroidetes ratio compared with the vehicle group. In addition, anti-fatigue activity and exercise performance were evaluated by investigating the exhaustive swimming time, forelimb grip strength and serum levels of lactate, ammonia, glucose, blood urea nitrogen (BUN), creatine kinase (CK) and lactate dehydrogenase (LDH) after swimming. The NCE-1X and NCE-5X groups showed a significantly longer exhaustive swimming time and higher relative forelimb grip strength than the vehicle group. Tissue glycogen content, an important energy source for exercise, increased significantly with NCE supplementation.. Taken together, our results indicate that NCE supplementation alters the gut microbiota composition and aids in overcoming physical fatigue. Curcumin may be acting on the gut microbiome to modulate the gut system towards improving exercise performance.

Myelofibrosis (MF) is characterized by shortened survival and a greatly compromised quality of life. Weight loss and cachexia seem to be the most important factors influencing survival in patients with MF. The aim of this study was to assess the efficacy of an integrated supportive therapy in improving cachexia and MF-related symptoms.. We reported on a case of a patient with MF who presented with weight loss and cachexia associated with severe anemia, fatigue, fever, and bone pain. The circulating levels of inflammatory, oxidative stress parameters, hepcidin, and erythropoietin were evaluated and were above normal ranges. The patient was treated with a multitargeted approach specifically developed for cachexia including oral l-carnitine, celecoxib, curcumin, lactoferrin, and subcutaneous recombinant human erythropoietin (EPO)-α.. Surprisingly, after 1 y, cachexia features improved, all MF symptoms were in remission, and inflammatory and oxidative stress parameters, hepcidin, and EPO were reduced.. Because our protocol was targeted at inflammation and the metabolic state, its effectiveness may emphasize the role of inflammation in the pathogenesis of MF symptoms and demonstrates a need for the study of new integrated therapeutic strategies.

Curcumin (CCM) is a well-known phytocompound and food component found in the spice turmeric and has multifunctional bioactivities. However, few studies have examined its effects on exercise performance and physical fatigue. We aimed to evaluate the potential beneficial effects of CCM supplementation on fatigue and ergogenic function following physical challenge in mice. Male ICR mice were divided into four groups to receive vehicle or CCM (180 μg/mL) by oral gavage at 0, 12.3, 24.6, or 61.5 mL/kg/day for four weeks. Exercise performance and anti-fatigue function were evaluated after physical challenge by forelimb grip strength, exhaustive swimming time, and levels of physical fatigue-associated biomarkers serum lactate, ammonia, blood urea nitrogen (BUN), and glucose and tissue damage markers such as aspartate transaminase (AST), alanine transaminase (ALT), and creatine kinase (CK). CCM supplementation dose-dependently increased grip strength and endurance performance and significantly decreased lactate, ammonia, BUN, AST, ALT, and CK levels after physical challenge. Muscular glycogen content, an important energy source for exercise, was significantly increased. CCM supplementation had few subchronic toxic effects. CCM supplementation may have a wide spectrum of bioactivities for promoting health, improving exercise performance and preventing fatigue.

Anorexia is a common symptom for patients with advanced cancer. Gentian, ginger, and turmeric have traditionally been used to stimulate appetite. We tested these agents in combination, in a pilot study to assess tolerability in patients indicating 4/10 or worse anorexia on the Edmonton Symptom Assessment System, and who were not currently on chemotherapy. We collected exploratory data on the patient's appetite using a visual analogue scale.. Between 2009 and 2012, 17 patients were enrolled in arm 1 (turmeric 1 g and ginger 1 g orally twice daily, and gentiana lutea tincture 1 mL three times a day, for 14 days). The three patients enrolled in arm 2 received the same doses of ginger and turmeric but no gentian. All patients completed a daily appetite diary and a weekly symptom assessment.. In arm 1, seven patients (41%) completed treatment. Seven patients (41%) stopped early because of unacceptable toxicity or patient-initiated discontinuation, and 3 stopped because of other reasons. All patients in arm 2 stopped taking the study medication within few days of starting the treatment, leading the study committee to recommend stopping the trial. The most common adverse effects attributed to study drugs were nausea (6 patients), vomiting (3), fatigue (3), diarrhea (2) and bloating (2). There was no statistically significant effect seen on appetite.. At the doses used in this study, the combination of ginger, turmeric, and gentian is not tolerated well in cancer patients. Future studies should use fewer agents or lower doses.
