In order to be eligible to participate in this study as an SSc patient, a subject must meet all of the following criteria:

o Skin thickening of the fingers (only count the higher score)

o Fingertip lesions (only count the higher score)
? Digital tip ulcers (2 points)
? Fingertip pitting scars (3 points)
o Telangiectasia (2 points)
o Abnormal nailfold capillaries (2 points)
o Pulmonary involvement (maximum score is 2)
? Pulmonary arterial hypertension (2 points)
? Interstitial lung disease (2 points)
o Raynaud’s phenomenon (3 points)
o SSc-related autoantibodies (maximum score is 3)
? Anticentromere (3 points)
? anti–topoisomerase I [anti–Scl-70] (3 points)
? anti–RNA polymerase III (3 points)
• Written informed consent
Controls:

Health Condition(s) or Problem(s) studied
|
Systemic sclerosis (SSc) is a rare progressive autoimmune disease hallmarked by severe vasculopathy. Patients are prone to enhanced calcification of skin and the vasculature. Active calcifications may not only occur in the skin of patients with clinically overt calcinosis cutis, but also in SSc patients without. Since calcification is strongly associated with local inflammation, it may very well occur in internal organs and serve as an early proxy for long-term SSc-related complications.

Therapeutic area: Diseases [C] - Skin and Connective Tissue Diseases [C17]

Intervention(s)
|
Product Name: Sodium fluoride 18F Product Code: EMA/CHMP/212874/2015 Pharmaceutical Form: Injection
|
Primary Outcome(s)
|
Main Objective: 1. To assess serum calcification propensity (T50) in SSc patients compared with healthy age and gender-matched controls;
|
Timepoint(s) of evaluation of this end point: At baseline
|
Secondary Objective: 2. To assess serum T50 in SSc patients with overt calcinosis cutis as compared to age and gender-matched SSc patients without; 3. To assess other serum markers of the calcification process in SSc patients compared with healthy age and gender-matched controls as compared to age and gender-matched SSc patients without; 4. To assess serum T50 and other serum markers of the calcification process compared with established markers of the underlying disease process; 5. To assess serum T50 compared with non-invasive markers of micro- and macrovasculopathy in patients with SSc; 6. To assess serum T50 compared with SSc-related skin and internal organ complications; 7. To study associations with expression of markers involved in the calcification process in skin biopsies by immunohistochemistry; 8. To assess whether AGEs/HMGB1-RAGE interactions lead to increased IFN-1 signature and profibrotic and osteogenic differentiation of fibroblasts isolated from skin biopsies;
|
Primary end point(s): 1. Degree of serum T50;
|
Secondary Outcome(s)
|
Secondary end point(s): 2. Degree of other serum markers of the calcification process: calcium; phosphorus; parathormone; fetuin-A; FGF23; aKlotho;
3. Degree of blood markers involved in inflammation, calcification and endothelial dysfunction: plasma AGEs (CML, pentosidine and MG-H1); HMGB1; carbonyl markers; skin AF as marker of dermal AGE accumulation (biomarkers of the AGE-RAGE axis); ET-1; C-reactive protein, erythrocyte sedimentation rate (ESR), IL-6, whole blood IFN- I signature (biomarkers of endothelial activation and inflammation); VEGF, IL-8, angiogenic T cells, TIE2 positive monocytes (biomarkers of angiogenesis);
4. Degree of vascularopathy measured by: capillary microscopy; arterial stiffness measured by PWV; digital artery involvement assessed with ultrasound;
5. Degree of cardiac involvement by cardiac ultrasound, pulmonary involvement by conventional lung function (FVC, DLCO), and subsequent HRCT upon indication, renal involvement by kidney function (24-hours creatinine clearance, proteinuria, and glomerular erythrocyturia) and gastro-intestinal involvement by conventional oesophageal motility scan;
6. Degree of markers involved in the calcification process as well as biomarkers of progression to SSc in skin biopsies: degree of fibrosis (TGFß, collagen); aKlotho; FGF23; myxovirus resistance gene A (MxA) which is a marker for IFNa, TLR 4 and TLR 8;
7. Degree of fibroblasts sensitivity to calcification and proinflammatory mechanisms by: CML-modified-bovine serum albumin (BSA); HMGB1, RAGE, and TGFß.
