简要总结
Patients eligible for the study will be selected on Fridays during the HIV consultation at the Infectious Diseases Department. Patients that meet the inclusion and exclusion criteria, will be randomized and assigned in two groups 1:1. A group will start intervention with FMT (fecal matter transplant) through frozen capsules and after seven days, antiretroviral therapy (ART) will be started. Patients in the other group will be given placebo capsules and after seven days ART will be started. The frozen capsules of FMT will be ingested orally with a frequency of 15 capsules every 12 hours for 4 doses 7 days prior ART start and on weeks 0, 4, 8 and 12 after ART start. Subsequently, blood samples will be taken to monitor the immune status with CD4 T lymphocytes and HIV viral load during week 0, 4, 8, 12 and 24 after ART start.
Throughout the study period, subjects can carry out a free diet, moderate alcohol intake, perform their daily activities and abstain from any of the elimination criteria. Medical consultations will be made on days -7 to ART start, day 1, 30, 60, 90 and 120 after ART start, where clinical examination and elimination criteria will be evaluated.
详细描述
Study design: Prospective controlled study experimental comparative Study duration: 1 year The number of patients to enroll: 20 patients. After being randomized, selected patients who meet the criteria for inclusion and exclusion will be assigned 1:1 in two groups. A group will start treatment with FMT through frozen capsules, and ART at the same time; and another group will star placebo capsules and ART.
The frozen capsules will be ingested orally at a frequency of 15 capsules every 12 hours for four doses 7 days prior ART start and on weeks 0, 4, 8 and 12 after ART start. Each capsule must be ingested over a period no longer than 1 hour of the anterior capsule.
Subsequently, blood samples will be taken through peripheral vein puncture with the extraction of 10 ml of venous blood to monitor the immune status with CD4 T lymphocytes and HIV viral load. A total of 4 blood samples will be taken during week 4, 8, 12 and 24 after ART start.
Medical consultations will be made every 4 weeks, on days -7 days prior ART start, day 1, 30, 60, 90 and 120 where vital signs, symptoms or signs of organ systems, determination of weight, BMI, adverse effects and elimination criteria will be assessed.
In addition, feces samples from each patient will be taken during medical consultation on week 0, 8 and 24 after ART start to evaluate the modification of the intestinal microbiome after the intervention on both groups.

盲法说明
Neither patients, nor investigators are allowed to know about which group of patients is going to receive placebo and which one faecal microbiota capsules. The laboratory that provide us the capsules is going to divide and randomize our sample of patients, and also register the information in a data base.

结局指标
主要结局
Levels of CD4 cells
时间窗: 6 months
The efficacy of FMT in obtaining a faster immunologic response measured in rise of CD4 lymphocyte countTMF capsules, will have a faster rise in cell count than those who don´t receive them.
次要结局
- Tolerability of FMT capsules(6 months)
