curcumin and Anorexia

We aim to investigate the effect of curcumin on preventing cancer anorexia-cachexia syndrome (CACS) via through mechanism of inhibition on NF-kB signal pathway. Outcome measurement for primary end point was improvement of body tissue composition, and the secondary end points were body weight and body mass index, hand grip muscle strengthening, and safety.. This is randomized, double-blind, placebo-controlled phase ll a study, 33 patients with CACS in solid malignancy were enrolled and randomized in 1:1 to receive oral curcumin (at a dose of 800 mg twice daily) or placebo for 8 weeks.. All parameters of body compositions were not statistically significant different between two groups, which were consist body fat mass [-1.25(SEM 0.87) vs. +0.63(SEM 0.55); p=0.119], skeletal muscle mass [-0.35(SEM 0.60) vs.+0.33(SEM 0.42); p=0.408] and percent body fat [-0.47(SEM 0.95) vs. -0.29(SEM 0.82); p=0.893] including with basal metabolic rate [-13.47(SEM 21.94) vs. +15.30(13.76); p=0.336]. The average of weight loss was also not statistically significant different between two groups. [-1.4 kg(SEM 0.89) in curcumin vs-1.12 kg(SEM 0.73), p=0.810]. Notably, patient with curcumin had less reduction of hand-grip muscle strength on both hands [Rt. handed: -2.47 in curcumin vs. -5.36 in placebo; p=0.318] [Lt. handed: -1.98 vs. -5.43; p=0.317], and basal metabolic rate than placebo group. Most adverse events were grade 1 on both groups similarly.. Curcumin was not shown to be superior to placebo with regard to increasing the body composition in cancer patients with CACS. However, curcumin might show some clinical benefits, including slow progression of hand-grip muscle strength loss, and basal metabolic rate. Further investigations should be explored.

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.
