Clinical Trial Summary

The facial-glenohumeral muscular dystrophy type 1 (DMFSH1) is characterized by a selective and asymmetrical involvement of the facial muscles, the shoulder girdle and the anterolateral lodge legs. Genetically, the disease is transmitted in an autosomal dominant manner and is caused by a pathogen contraction of repeat units (UR) say D4Z4 localized to the telomeric portion of chromosome 4qA. The loss of UR causes hypomethylation of DNA and chromatin relaxation of the region that lead to inappropriate expression of DUX4 retrogene highly toxic. The inappropriate expression induces a T cell reaction inflammatory response that participate and increase muscle damage. In favor of this hypothesis, several muscle MRI studies have shown that atrophy and fibro-adipose degeneration (hyper signal in T1) were preceded by the appearance of muscle inflammation (hyper signal T2STIR) confirmed on histologically and dysregulation of genes involved in adaptive and innate immunity. scientific hypothesis and potential benefits: the investigateur hypothesize that in patients of DMFSH1, the immune system cells may participate in the pathophysiology of the disease through changes in serum secretion of one or more cytokines and / or a modification of the response of inflammatory cells in some cell damage stimuli. Design: this is a single-center pilot study, interventional. In this study, the investigator will assay the serum cytokines and changes in peripheral blood cells of the expression of cytokines in response to some stimuli in 20 patients with Type 1 DMFSH genetically confirmed at an intermediate stage of clinical disease (kept walking, but at least one muscle of lower limbs reached) and compare with controls from the CYTOKINAGE study. The investigator will also carry patients clinical testing (MMT sum score) and functional (6minute test march MFM) and a MRI not injected whole body (T1 sequences + and T2STIR) to study the relationship between these parameters and secretion cytokines or serum in response to certain stimuli Main objective: to compare serum levels of IL-6 in patients with DMFSH and controls.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Comparison of serum IL-6 levels between FSHD1 patients and control subjects (from other previous studies) comparable in terms of age and sex	Serum IL-6 levels will be measured using v-plex technology (MSD) in FSHD1 patients and compared with results obtained in paired control subjects from 2 cohorts (NCT00998231 and Cytokinage study NCT02660723)	21 months
Secondary	Comparison of serum levels of 28 oher pro-inflammatory cytokines between FSHD1 patients and control subjects	Serum levels of 28 other cytokines will be measured using v-plex technology (MSD) in FSHD1 patients and compared with results obtained in paired control subjects	21 months
Secondary	Comparison of cytokines produced upon in vitro stimulation of blood cells in FSHD1 patients and control subjects	Cytokine production will be induced in blood cells by non-specific stimulation with LPS, ATP+LPS-EB or poly (I:C) in FSHD1 patients and compared with results obtained in control subjects	21 months
Secondary	Evaluation of potential correlations between cytokines levels (either in the serum or produced upon in vitro stimulation) and clinical severity in FSHD1 patients	Clinical severity and muscle impairment will be evaluated using standardized clinical scales (Manual Muscle Testing, Motor Function Measure-32, 6-minute walk test, age-corrected Clinical Severity Score)	21 months
Secondary	Evaluation of potential correlations between cytokines levels (either in the serum or produced upon in vitro stimulation) and muscle MRI caracteristics in FSHD1 patients	Whole body MRI will be recorded (T1 and T2STIR sequences) in order to evaluate muscle oedema, inflammation and degeneration	21 months
