Jennifer Matthews: 8-month-old Mariana has just arrived from Guatemala. Her adoptive mother, Marjorie Fujara, is ready for the challenges of motherhood, but at age 41, Marjorie faces a more serious challenge. 8 years ago, doctors diagnosed Marjorie with multiple sclerosis. Marjorie Fujara: It was devastating. My mother was diagnosed with MS and had a very aggressive course with hers. Jennifer Matthews: Marjorie's mother died from MS after 12 years. Today, Marjorie is in a trial to test a new treatment -- a drug that is used for diabetes. Dr. Douglas Feinstein: The relationship between type 2 diabetes and multiple sclerosis -- there probably isn't any really strong correlation, and it's just a serendipitous discovery that we came across. Jennifer Matthews: The drug Pioglitazone is known to type two diabetes patients as actos (ack-tose). Lab studies with the drug for MS look encouraging. Dr. Douglas Feinstein: This is the mass model for multiple sclerosis. Jennifer Matthews: So far, things are looking good for Marjorie. Her symptoms are not flaring up as often, and she has no side effects. Marjorie Fujara: Just knowing there are people -- bright, dedicated researchers out there, really gives me a lot of hope. Jennifer Matthews: If the study results continue to show promise, Pioglitazone could become the first treatment for MS taken in pill form, eliminating the need for injections. This is Jennifer Matthews reporting.
