Experimental: Single Arm
Interferon beta 1a, oral doxycycline
Drug: Interferon beta 1a, oral doxycycline
Patients took intramuscular interferon beta 1a, 30 micrograms, for 3 months then added oral doxycycline, 100 daily with the interferon for 4 months.
Other Name: Avonex
- Gadolinium-enhancing (Gd+)Lesion Number Change. [ Time Frame: 8 months ]Before treatment is the number of lesions per image from months -3, -2, -1, and 0. During treatment is the number of lesions from months 1,2, and 3. The mean number of Gd+ lesions during each treatment period was calculated for each patient as the total number of Gd+ lesions observed across all images divided by the number of images. Hence, the mean number of Gd+ lesions per patient represents the number of lesions per MRI.
- Relapse Rates, Serum Matrix Metalloproteinase 9 Levels, Transendothelial Migration of Monocytes [ Time Frame: 8 months ]Only 1 patient relapsed. Correlations between decrease serum metalloproteinase 9 levels and enhancing lesion activity reduction. Transendothelial migration of monocytes was suppressed. Adverse effects were mild. No adverse synergistic effects of combination therapy.
- Determine Safety and Tolerability of Combination Therapy With Avonex Plus Doxycycline [ Time Frame: 8 months ]
- Determine Pre- and On-treatment Cytokine ELISA, MMP ELISA and Bioassay [ Time Frame: 8 months ]
