Measure
Azathioprine
Patients in this group will receive 50 mg of azathioprine, two times each day and gradually increased to maximum dose of 3 g daily with the aim of lymphocytes count less than 1500. Azathioprine: Patients are started with Azathioprine 50 mg tablets, taken orally twice a day. The medication dose is increased gradually with the aim of lymphocytes count bellow 1500 and to the maximum dose of 3 g Azathioprine per day. Cell blood count is checked once a week in the first month of treatment, once every two weeks in the second month of treatment, and monthly in the third month of treatment to make decision about medication dose.
Rituximab
Patients in this group will receive 1g of Rituximab in 500 cc normal saline serum through intravenous infusion with two weeks intervals (as one course) and each course of treatment is repeated every 6 months. Rituximab: Patients will receive 1 g of Rituximab (two vials of RediTux 500 mg/50 ml) in 500 cc normal saline serum through intravenous infusion and this will be repeated two weeks later. This cycle will be repeated every 6 months.

SECONDARY outcome

Timeframe: one year

Population: Per protocol analysis

expanded disability status scale will be measured in the baseline and after 12 months of intervention. Expanded disability status scale (EDSS) is a measure of disability for patients. The score ranges from 0-10, with 0 showing normal neurological exam and 10 showing death due to the disabling disease. Thus, higher scores represent more profound levels of disability.
