Cancer anorexia–cachexia syndrome (CACS) is usually found in advanced cancer patients. CACS is a multifactorial process which comprises skeletal muscle and adipose tissue loss which may be compounded by anorexia and a dysregulated metabolic state. The hypothesis of this study was that curcumin will increase body compositions and body weight in patients with solid malignancy and CACS when compared to placebo after adjusting by age, gender, primary site of cancer, stage of cancer, performance status, and supplementary nutrition support. This study was a double-blind, placebo-controlled randomised phase lla study. A total of 46 patients were enrolled, of whom 33 underwent 1:1 block of four randomisations. Seventeen patients were randomly assigned to receive curcumin at dose of 800 mg twice daily orally and sixteen patients were randomly assigned to received placebo. Results show that curcumin supplementation: (1) did not statistically significantly improve body compositions and body weight when compared to placebo; (2) may cause clinical benefit in term of hand grip muscle strength and slow progress of CACS by decreasing in basal metabolic rate and preventing the decline in serum albumin; and (3) administered orally for two months at a dose of up to 2 grams daily appeared safe and no serious adverse events were reported. Authors conclude that curcumin inhibited process of CACS via reduction of basal metabolic rate and slowed down the progression of hand-grip muscle strength loss. Furthermore, nuclear factor kappa B [regulator of gene expression] levels merit further exploration as potentially suitable predictive biomarker for CACS treatment with curcumin.
Abstract
OBJECTIVE 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. METHODS 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. RESULTS 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. CONCLUSION 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.

Plain language summary
Superrefractory status epilepticus (SRSE) is a neurologic emergency that persists despite anti-seizure medication. The ketogenic diet (KD) has been shown to be successful for treating epilepsy and recent retrospective studies suggest KD may be effective for treating SRSE. The aim of this clinical trial was to investigate the feasibility, safety and efficacy of a ketogenic diet on SRSE in adults. After screening, this prospective multi-centre study enrolled 15 participants with SRSE. Participants received a classic ketogenic diet via gastronomy tube. Of the 14 participants whom completed KD treatment SRSE resolved in 11 participants. Five patients ultimately died. This study found KD is feasible in adults with SRSE, and further randomised controlled trials are required to establish comparative safety and efficacy.
Abstract
OBJECTIVE To investigate the feasibility, safety, and efficacy of a ketogenic diet (KD) for superrefractory status epilepticus (SRSE) in adults. METHODS We performed a prospective multicenter study of patients 18 to 80 years of age with SRSE treated with a KD treatment algorithm. The primary outcome measure was significant urine and serum ketone body production as a biomarker of feasibility. Secondary measures included resolution of SRSE, disposition at discharge, KD-related side effects, and long-term outcomes. RESULTS Twenty-four adults were screened for participation at 5 medical centers, and 15 were enrolled and treated with a classic KD via gastrostomy tube for SRSE. Median age was 47 years (interquartile range [IQR] 30 years), and 5 (33%) were male. Median number of antiseizure drugs used before KD was 8 (IQR 7), and median duration of SRSE before KD initiation was 10 days (IQR 7 days). KD treatment delays resulted from intravenous propofol use, ileus, and initial care received at a nonparticipating center. All patients achieved ketosis in a median of 2 days (IQR 1 day) on KD. Fourteen patients completed KD treatment, and SRSE resolved in 11 (79%; 73% of all patients enrolled). Side effects included metabolic acidosis, hyperlipidemia, constipation, hypoglycemia, hyponatremia, and weight loss. Five patients (33%) ultimately died. CONCLUSIONS KD is feasible in adults with SRSE and may be safe and effective. Comparative safety and efficacy must be established with randomized placebo-controlled trials. CLASSIFICATION OF EVIDENCE This study provides Class IV evidence that in adults with SRSE, a KD is effective in inducing ketosis.
