Determination of the Biological Activity of Serum From Patients

Status Recruiting

Clinical Trial Summary

The main objective of the study is to determine the influence of patient sera before and after probiotic intervention on the behavior of bone cells (osteoblasts and osteoclasts). The secondary objectives are to assess the activity of bone cells and the course of rheumatoid arthritis before and after the consomption of probiotics.

Clinical Trial Description

The written consent of the subjects will be obtained after full information of the aims, nature and possible risks of the study. Before inclusion, subjects will undergo a medical check-up including an interview on personal and family history and drug treatments taken as well as a standard medical examination including weight, height and blood pressure measurement. . Their compliance with the inclusion / exclusion criteria will be verified during this review. An interview with personnel involved in the research (a dietician / study Research clinic assistant, etc.) will also be carried out as well as a biological selection assessment. As part of this study, the subjects will come a total of 7 times to the Emile ROUX hospital in Le Puy en Velay. The probiotic treatment will begin between 1 and 3 weeks after the inclusion visit. The volunteers / patients recruited will have a volume of blood sampled and a stool collected before the start of the probiotic treatment (T = 0) and at the end of the treatment (T = 4 weeks). The study consists of three periods of probiotic treatment of 4 weeks each interspersed with a wash-out period of 3 weeks in accordance with the recovery period necessary between two blood samples. The sera thus obtained will then be analyzed to determine their biological activity with regard to the induction of changes in the behavior of bone cell models: osteoformin cells (osteoblasts) and osteo-resorbent cells (osteoclasts). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
