Study Details

Study Description

Brief Summary

The goal of this interventional study is to compare the effectiveness of two different glucocorticoid regimens for treatment of active moderate-to-severe Graves' orbitopathy. The main questions it aims to answer are:

Are the two glucocorticoid regimens similarly effective?
Do the two glucocorticoid regimens have similar safety profile? The patients involved are treated with one of the two glucocorticoid regimens. Their ocular status, therapeutic response and quality of life reassessed during the treatment, at its end, and 3 month later.

Graves Ophthalmopathy	Drug: Methylprednisolone

Detailed Description

Systemic glucocorticoids are the mainstay of treatment for active moderate-to-severe Graves' orbitopathy. However, there are a number of different glucocorticoid regimens with different total dosage, schemes of administration and duration. The goal of this interventional study is to compare the effectiveness of two different glucocorticoid regimens for treatment of active moderate-to-severe Graves' orbitopathy. The main questions it aims to answer are:

Are the two glucocorticoid regimens similarly effective?
Do the two glucocorticoid regimens have similar safety profile? The patients involved are treated with one of the two glucocorticoid regimens. The first group is treated with modified monthly regimen, including 3 pulses of 3 infusions of 500 mg methylprednisolone administered in three consecutive months, with application of 125 mg methylprednisolone intramuscularly once per week between the pulses. Total cumulative dose - 5.5. g., duration - 3 months. After completion of the venous infusions, a low dose peroral glucocorticoid therapy is prescribed for the next 3 months. The second group is treated with weekly glucocorticoid regimen: 6 infusions of 500 mg methylprednisolone during the first 6 weeks followed by 6 infusions of 250 mg methylprednisolone during the next 6 weeks. Total cumulative dose - 4.5 g., duration - 3 months. Patients' ocular status and therapeutic response are assessed at 1st, 3rd and 6th months; quality of life - at 3rd and 6th month.
