Prevalence of Hyperprolactinemia in Systemic Scleroderma (SCLERO-PRL)

Assessment of the Prevalence of Hyperprolactinemia in Systemic Scleroderma

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

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Patients with systemic sclerosis; The study will be systematically offered to any scleroderma patient seen in scheduled hospitalization	Biological: blood 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
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; 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 is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	At 2 years

Secondary Outcome Measures

Outcome Measure	Time Frame
the prevalence of hyperprolactinemia between scleroderma patients and healthy subjects matched by age and sex	At 2 years
the associations between prolactin levels and clinical (scleroderma phenotype, visceral involvement) and biological (inflammation, antibodies, cytokines) manifestations in systemic sclerosis	At 2 years
association between prolactin levels and biological markers of the immune system in scleroderma patients	At 2 years
