Diagnosis and Treatment of Systemic and Localized Scleroderma CME

Scleroderma or progressive systemic sclerosis is diagnosed clinically by typical features of skin thickening, Raynaud’s phenomenon and visceral organ involvement, and serologically by distinct autoantibody subsets. These differentiate the disease into the ‘limited’ and ‘diffuse’ variants. In addition, a distinct form of scleroderma, termed ‘localized’ scleroderma, is characterized by skin thickening in the absence of visceral involvement. Treatment of scleroderma in the past was largely symptomatic and with immunosuppressives, acting against the organ system involved and the aberrant immune system. Recently, with newer insights into disease pathogenesis, drug therapies targeting the pathogenetic mechanisms of fibrosis, vasculopathy and autoimmunity are being evolved. Some of these newer therapies are the endothelin receptor blockers, phosphodiesterase inhibitors, tyrosine kinase inhibitors and autologous stem cell transplant, while others are still evolving. They may hold the key to improved future outcome of this disease, which was once thought to be potentially incurable.

FDA Approves Zoster Vaccine for Younger Adults
Susan Jeffrey
March 24, 2011 ? The US Food and Drug Administration (FDA) announced today approval for a vaccine to prevent herpes zoster, also known as shingles, in adults age 50 to 59 years.
The vaccine (Zostavax, Merck & Co., Inc.), a live attenuated virus vaccine, was already approved for prevention of zoster in adults 60 years of age and older in May 2006.
«The likelihood of shingles increases with age. The availability of Zostavax to a younger age group provides an additional opportunity to prevent this often painful and debilitating disease,» said Karen Midthun, MD, director of FDA’s Center for Biologics Evaluation and Research, in a news release.
Approval was based on a multicenter placebo-controlled trial conducted in the United States and 4 other countries among approximately 22,000 adults who were 50 to 59 years of age. Study participants were followed for at least 1 year for the development of zoster. Results showed that compared with placebo, the vaccine reduced the risk of developing zoster by approximately 70%.
The most common side effects observed were redness, pain, and swelling at the site of injection and headache.
