Chronic Fatigue Syndrome, also known as Myalgic Encephalomyelitis (CFS / MS) is a medical entity characterized mainly by debilitating and prolonged fatigue lasting more than 6 months, post-exertion fatigue (physical and / or mental), non-sleep restorative, cognitive impairment and orthostatic intolerance with prolonged recovery that is not relieved by rest. Currently, the etiopathogenic mechanisms of the disease are not known, although mitochondrial dysfunction with bioenergetic immuno-metabolism alterations, oxidative stress, and immuno-inflammatory response stands out. At present, there is no diagnostic test, nor effective treatment in the disease. ImmunoVita, is a food supplement composed of the latest yeast beta-glucans, in addition to vitamin D3, vitamin B6 and zinc, which could contribute to the normal functioning of the immune system and the inflammatory response.
In patients with CFS / ME, neuroimmune, gastrointestinal, autonomic and cardiovascular alterations have been observed, among others. CFS / ME is characterized by disabling chronic fatigue, non-restorative sleep, severe intolerance to physical exercise, neurocognitive dysfunction with changes in concentration and immediate memory and neurovegetative symptoms in the form of dizziness, syncopes and alterations in bowel and bladder rhythm . Within the etiopathogenic hypotheses of the disease, they are involved if patients treated with ImmunoVita® could significantly reduce the scores on the scale of the impact of fatigue, sleep problems, neurovegetative dysfunction, anxiety / depression, and improve the quality of life compared to the placebo group. Based on the different etiopathogenic hypotheses of the syndrome, various mechanisms would be involved, which could modulate them, the ImmunoVita food complex. 1. Do patients with CFS / ME have high scores on the fatigue impact scale, hospital anxiety-depression scale and Pittsburg sleep quality questionnaire? 2. Do patients with CFS / ME have high scores in the autonomic dysfunction symptomatology scale? 3. Do patients with CFS / ME have low scores in the SF-36 quality of life questionnaire? 4. Do CFS / MS patients treated with ImmunoVita significantly reduce the scores on the scales of fatigue, anxiety / depression and autonomic dysfunction? 5. Will patients with CFS / ME treated with ImmunoVita significantly increase the scores on the SF-36 quality of life questionnaire? GOALS Main goal The objective of this study is to assess the efficacy of active ImmunoVita® in patients with CFS / MS vs. placebo in the perception of fatigue, evaluated through the scale of perception of fatigue (FIS-40). Secondary goals: 1. Evaluate the efficacy of active ImmunoVita® in patients with CFS / MS vs. placebo in the improvement of sleep dysfunction, through the Pittsburg questionnaire. 2. Analyze the efficacy of active ImmunoVita®, in patients with CFS / ME vs. placebo in the improvement of anxiety-depressive symptomatology, through the hospital anxiety-depression scale (HAD). 3. Evaluate the efficacy of active ImmunoVita®, in patients with CFS / ME vs. placebo in the improvement of the quality of life, through the SF-36 questionnaire.

Perception of fatigue (FIS-40).
The Fatigue Impact Scale (FIS-40) is a 40-item questionnaire designed to assess fatigue symptoms as part of an underlying chronic condition. It includes three domains reflecting the perceived feeling of fatigue: physical (10 items), cognitive (10 items) and psychosocial functions (20 items). Each item is scored from 0 (no fatigue) to 4 (severe fatigue). The overall score is calculated by adding together the responses to the 40 questions (ranging from 0 to 160). Higher scores indicate more functional limitations due to fatigue.
Time frame: 9 months
Sleep dysfunction (Pittsburg questionnaire)
The Pittsburgh Sleep Quality Index (PSQI) is a 19-item self-administrated questionnaire commonly used to assess sleep disturbances over a 1-month interval. Scores are acquired on each of seven domains of sleep quality: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. Each domain is scored from 0 to 3 (0 = no problems and 3 = severe problems). The overall PSQI score ranges from 0 to 21 points, with scores of \> 5 indicating poorer sleep quality.
Time frame: 9 months
Hospital anxiety-depression scale (HAD)
To assess anxiety and depression symptoms the Hospital Anxiety and Depression Scale (HADS) was used; a validated 14 item self-reported measure (seven items associated with anxiety symptoms and seven with depression) over the last week. Each item is scored on a 4-point Likert scale (e.g., 0 = as much as I always do; 1 = not quite so much; 2 = definitely not so much; and 3 = not at all) giving maximum subscale scores of 21 for depression and anxiety, respectively. Scores of 0-7 are interpreted as normal; scores of 8-10 reflect mild symptoms, 11-14 moderate, and 15-21 severe for either anxiety or depression. The global HADS score ranges from 0 (no anxiety/depression) to 42 (severe anxiety/depression).
Time frame: 9 months
Quality of life (SF-36)
The SF-36 questionnaire was used to assess health-related quality of life. This is a 36-item broadly-based self-report survey of physical and mental functioning status related to health. The SF-36 assesses functioning on eight subscales including domains of physical functioning, physical role functioning, bodily pain, general health perception, vitality, social role functioning, emotional role functioning, and mental health. Lower scores indicate a more negative impact of an individual's health on functioning.
