E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To test the efficacy and safety of two different dosages of pulsed iv methylprednisolone for the treatment of dysthyroid optic neuropathy (DON):
regimen 1) 1g of MP administered daily for 3 consecutive days, for 2 consecutive weeks, tapered off with 8 infusion of 250 mg of MP (cumulative dose= 8g)
regimen 2) 500 mg of MP administered daily for 3 consecutive days, for 2 consecutive weeks, tapered off with 8 infusion of 250 mg of MP (cumulative dose= 5g)
|
- confrontare efficacia e sicurezza di due dosaggi di Metilprednisolone, somministrato per via endovenosa (IVMP), impiegati per il trattamento dell'otticopatia distiroidea acuta (DON):
schema 1) 1g di MP ripetuto per 3 giorni consecutivi di 2 settimane consecutive seguito da 8 infusioni da 250 mg (dose cumulativa = 8g)
schema 2) 500 mg di MP ripetuto per 3 giorni consecutivi di 2 settimane consecutive seguito da 8 infusioni da 250 mg (dose cumulativa = 5g) |
|
E.2.2 | Secondary objectives of the trial |
1. Safety and tolerability of the two therapeutic protocols.
2. Factors influencing clinical response
3. Improvement in quality of life
4. Inactivation of GO (CAS ≤ 2)
5. Need for additional surgical treatment. |
1. valutare la sicurezza dei due schemi terapeutici utilizzati
2. individuare eventuali variabili che possano essere utilizzate come fattori predittivi di risposta alla terapia
3. valutare il miglioramento della qualità di vita del paziente
4. capacità dello steroide di inattivare la fase infiammatoria della malattia (CAS ≤ 2)
5. necessità di procedure chirurgiche entro l’anno dal trattamento
