E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective of our study is to investigate the effect of tofacitinib on serum levels of bone turnover markers (CTX ng/ml, P1NP ng/ml, BAP ng/ml) and modulators (DKK1 pmol/L, Sclerostin pmol/L, OPG pmol/L, RANKL pmol/L, PTH pg/ml, 25 OH vitamin D ng/ml) |
L'obiettivo principale del nostro studio è di studiare l'effetto di Tofacitinib sui livelli sierici dei marker di turnover osseo (CTX ng / ml, P1NP ng / ml, BAP ng / ml) e modulatori del turnover osseo (DKK1 pmol / L, Sclerostin pmol / L, OPG pmol / L, RANKL pmol / L, PTH pg / ml, 25 OH vitamina D ng / ml) |
|
E.2.2 | Secondary objectives of the trial |
1. changes versus baseline in hip and lumbar bone mineral density (BMD) by Dual X-ray Absorptiometry (DXA), hand BMD by DXR, bone erosions and anti-citrullinated peptides antibodies (ACPA), 2. to investigate the correlations between ACPA, bone turnover markers and modulators (BTM), bone mineral density (BMD) by Dual X-ray Absoptiometry (DXA), metacarpal index (MCI) and Bone Health Index (BHI) by and Digital X-ray Radiogrammometry (DXR), and bone erosions in patients with RA with short disease duration. 3. to evaluate the influence of tofacitinib on those outcomes and determinate if they are related to the effect on ACPA titer |
1. variazioni rispetto al basale della densità minerale ossea (BMD) dell'anca e lombare mediante Dual X-ray Absorptiometry (DXA), della BMD della mano mediante DXR, delle erosioni ossee e degli anticorpi anti-citrullinati (ACPA) 2. indagare le correlazioni tra ACPA, marcatori e modulatori del turnover osseo (BTM), densità minerale ossea (BMD) mediante Dual X-ray Absoptiometry (DXA), metacarpal index (MCI) e Bone Health Index (BHI) mediante Digital X-ray Radiogrammometry (DXR) e erosioni ossee in pazienti con AR con breve durata della malattia. 3. valutare l'influenza di tofacitinib su questi outcomes e determinare se sono correlati all'effetto sul titolo anticorpale di ACPA |
