E.5 End points |
E.5.1 | Primary end point(s) |
a) to measure the concentration of PEDF in subjects suffering from OI type VI at the end of the transfusion of a standard dose of plasma (12-15 ml / kg in single infusion), after 1 day, 7 days, 1 month plasma transfusion and before each transfusion, and to evaluate the time interval in which remains a quantity of PEDF equal to the levels of heterozygous subjects for the genetic defect (estimated about 1/5 of the normal values, about 1 mg / ml) establishing, at the end of the transfusions, the best dose of plasma to be administered and the best interval between any subsequent infusions of plasma. b) to evaluate at 1 month after the sixth plasma transfusion, the markers of bone apposition and reabsorption, the bone histomorphometry and densitometric parameters. c) to monitor the occurrence of any adverse events, particularly hemodynamic overload and transfusion reactions or allergic-type reactions febrile non hemolytic transfusion evaluating vital signs before, during and at the end of plasma transfusions, or within the following three hours. d) to monitor the possible occurrence of infectious diseases through the repetition of serology and NAT for HBV, HCV and HIV and serology for LUE at 6 months after the last transfusion |
a) misurare la concentrazione di PEDF nei soggetti affetti da OI tipo VI al termine della trasfusione di una dose standard di plasma (12-15 ml/Kg in unica infusione), dopo 1 giorno, 7 giorni, 1 mese dalla trasfusione di plasma e prima di ogni trasfusione, in modo tale da valutare l’intervallo di tempo in cui permanga una quantità di PEDF pari ai livelli dei soggetti eterozigoti per il difetto genetico (stimato circa 1/5 dei valori normali, circa 1 µg/ml) e stabilire, al termine delle trasfusioni, la miglior dose di plasma da somministrare e il miglior intervallo fra eventuali successive infusioni di plasma a scopo di successivo trattamento. b) valutare a distanza di 1 mese dalla sesta trasfusione di plasma i markers di riassorbimento e apposizione ossei, l’istomorfometria ossea e i parametri densitometrici. c) monitorare la comparsa di eventuali eventi avversi alla trasfusione, in particolare sovraccarico emodinamico e reazioni trasfusionali di tipo allergico o reazioni febbrili non emolitiche, valutando parametri vitali prima della trasfusione, durante e al termine della stessa e nelle prime tre ore immediatamente successive. d) monitorare l’eventuale comparsa di malattie infettive attraverso la ripetizione delle sierologie e NAT per HBV, HCV ed HIV e sierologie per LUE a distanza di 6 mesi dall’ultima trasfusione
