Sarah Hughes, right, and her mother, Fiona, have endured 24 years of Sarah's struggle with systemic juvenile idiopathic arthritis, a debilitating autoimmune disease. But a new treatment has given her another chance at life. Click through our gallery to learn more about Sarah's journey.
Fiona's twin, Sarah Jane (left), was only 8 when she was told that she would die prematurely from juvenile arthritis, but her symptoms didn't take a turn for the worse until she was 20. Growing up, Fiona shared a bedroom with Sarah Jane and was scared to sleep at night because her twin suffered from seizures. Instead, she would stay awake and keep watch.
This was the last birthday together for the twins before Sarah Jane died. Also pictured are Sarah (right, with Fiona) and Sarah Jane's daughter, Allison (left).
