Dual Drug Therapy Effective Against Pemphigus Vulgaris

While previous research on rituximab has sometimes found serious side effects, such as allergic reaction, Posner said there were virtually no side effects seen in this trial.

He said he thinks this drug combination would likely be helpful in less severe cases of pemphigus vulgaris, and he added that it could potentially be useful for treating other autoimmune diseases, such as rheumatoid arthritis, systemic lupus and type 1 diabetes.

"This therapy offers hope for this disease, and it could lead the way to treatment for other diseases that have a big impact on people's lives -- it needs to be investigated in other diseases so we can see how it works in other situations," Posner said.

Stanley said he doubted that rituximab would become a first-line treatment for pemphigus vulgaris anytime soon because the medication is quite costly and insurance companies would likely balk at paying for an expensive drug that isn't FDA approved specifically for treating pemphigus. The problem, he added, is that because pemphigus is so rare, it would be difficult to conduct a large enough trial to get such approval.

But, Posner suggested that while the rituximab/immune globulin combination treatment is more expensive initially, a cost analysis comparing all of the costs, including hospitalizations, might find the combination treatment is the cheaper alternative in the long run.
