Study summary

Systemic sclerosis is an autoimmune and inflammatory disease characterized primarily by fibrosis and vascular involvement. We know that the immune system is disrupted in systemic sclerosis, but there are probably other mechanisms to explain the disease, including deregulation of certain proteins such as prolactin

Groups and cohorts

  • Patients with systemic sclerosis

    The study will be systematically offered to any scleroderma patient seen in scheduled hospitalization

    Biological: blood test

  • Healthy subjects

    Healthy subjects who will donate blood to the French Blood Establishment (EFS) and matched to scleroderma patients on age (+/- 5 years) and sex

    Biological: blood test

Interventions

  • Biologicalblood test

    * to analysis prolactin in healthy subjects and scleroderma patients * then to analysis in only scleroderma patients: thyroid-stimulating hormone (TSH), thyroxine (T4), luteinizing hormone (LH), oestradiol, follicle-stimulating hormone (FSH), BAFF (B-cell activating factor), IL-6 (interleukin 6) and endoglin

What researchers measure

Primary outcomes

  1. the prevalence of hyperprolactinemia in scleroderma patients

    Rate of prolactin measured by immuno-chemiluminescence (Abbott Architect automaton). The presence of a defined hyperprolactinemia at the University Hospital of Lille: for women, prolactin level higher than 26.5 ng/mL and for men, higher than 19.4 ng/mL.

    Time frame: At 2 years

Secondary outcomes

  1. the prevalence of hyperprolactinemia between scleroderma patients and healthy subjects matched by age and sex

    Time frame: At 2 years

  2. the associations between prolactin levels and clinical (scleroderma phenotype, visceral involvement) and biological (inflammation, antibodies, cytokines) manifestations in systemic sclerosis

    Time frame: At 2 years

  3. association between prolactin levels and biological markers of the immune system in scleroderma patients

    Time frame: At 2 years
