From Wikipedia, the free encyclopedia

Juven is a medical food that is manufactured by Abbott Laboratories and used to provide nutritional support under the care of a physician in individuals with muscle wasting due to AIDS or cancer, to promote wound healing following surgery or injury, or when otherwise recommended by a medical professional.[1][2][3] It is a powdered nutritional supplement that contains 3 grams of calcium β-hydroxy β-methylbutyrate, 14 grams of L-arginine, and 14 grams of L-glutamine per two daily servings.[1]

Juven has been shown to increase lean body mass during clinical trials in individuals with AIDS and cancer, but not rheumatoid cachexia.[4][5][6] Clinical trials with Juven for AIDS have also demonstrated improvements in immune status, as measured by a reduced HIV viral load relative to controls and higher CD3+ and CD8+ cell counts.[note 1][4][6] The efficacy of Juven for the treatment of cancer cachexia was also examined in a phase 3 clinical trial which found a strong trend (i.e., p=.08) for an improvement in lean body mass relative to controls;[4][5][8] however, according to the authors of the trial itself and a systematic review that included it, the trial did not adequately test the ability of Juven to prevent or reverse the loss of lean body mass in individuals with cancer cachexia since the majority of participants did not complete the study.[4][8] Further research involving the treatment of cancer cachexia with Juven over a period of several months is required to adequately determine treatment efficacy.[4][5]

Vitamax, for example, is a chewable tablet designed to meet the specific vitamin needs of people with cystic fibrosis; Vascazen, meanwhile, contains purified omega-3 fatty acids for people with cardiovascular disease; Abbott Nutrition's Juven provides nutrients to people with HIV or AIDS experiencing excessive weight loss due to disease; ...

Interesting results were observed during cancer, notably, patients with advanced (stage IV) cancer receiving a HMB/ARG/GLN supplement gained 0.95 ± 0.66 kg of BM in 4 weeks and a change in body composition (FFM increase of 1.12 ± 0.68 kg). The FFM increase was maintained over the 24 weeks (May et al. 2002). Human immunodeficiency virus (HIV)-infected patients gained 3.0 ± 0.5 kg of BM after 8 weeks of HMB/ARG/GLN supplementation, mainly FFM (2.55 ± 0.75 kg). HMB/ARG/GLN supplementation also improved immune status, measured by increasing CD3 and CD8 cells and decreasing the HIV viral load. ... These results show that HMB/ARG/GLN can be safely used to treat AIDS- and cancer-related muscle wasting (Rathmacher et al. 2004). Berk et al. (2008) showed a strong trend towards higher FFM and BM in HMB/ARG/GLN-supplemented patients but they did not adequately test the ability of HMB/ARG/GLN to reverse or prevent cancer cachexia because most of patients did not complete the study. It was also demonstrated that both placebo and experimental amino acid mixtures significantly increased FFM, total body protein, arms and legs lean mass, and measures of physical function in rheumatoid arthritis patients but HMB/ARG/GLN supplementation was not superior to placebo in reversing rheumatoid cachexia (Marcora et al. 2005).

Looking at studies with proteins and other dietary supplements the combination of HMB, arginine, and glutamine showed interesting results ... In one study, 32 patients gained an average of about 2 kg of body weight.[21] This study was one of three studies confirming the positive effects of this combination in a variety of diagnoses/conditions such as HIV/AIDS patients and healthy adults.[40] Another study, on a far larger sample base of around 470 cancer patients, found no significant difference with regard to LBM after 8 weeks however a strong trend in the direction of an increase in LBM as measured by both bio-impedance and skin-fold measurements.[22] In summary, the effect of the combination of HMB, arginine, and glutamine on weight gain should be investigated in further studies on cancer patients investigating time periods of several months.
