 Advanced Viral Research Corp. Cites Influence of 'Product R' On Opportunistic Infections
 Dr. Shalom Z. Hirschman Discusses Recent Research on Human Papilloma Virus and Dire Need for Effective Drugs in New Online Forum
 YONKERS, N.Y.--(BW HealthWire)--June 29, 2000-- In his second online forum on Advanced Viral Research Corp.'s (OTCBB:ADVR - news) Web site -- adviral.com -- company President and CEO Dr. Shalom Z. Hirschman discusses the dire need for more effective drugs to treat the ``opportunistic'' infections that often develop in persons with AIDS.
 
 Opportunistic infections are the most devastating complications in people with AIDS. They occur as a result of the destruction of immune function by infection with the human immunodeficiency virus (HIV). Human papilloma viruses (HPV) are among the most common infections for which no therapy exists, or for which the existing therapy is only marginally effective and fraught with severe toxic side effects.
 
 As Dr. Hirschman writes, ``In persons whose immune systems have been compromised, these infections become much more severe and can be life threatening. At present, no effective drug has been approved (by the FDA) for the systemic treatment of disseminated HPV infection.''
 
 However, recent research by scientists at the Advanced Viral Research Institute has shown that Product R, an experimental drug being developed by the company as a broad spectrum antiviral, interferes with the actual replication and growth of HPV in cell culture. Earlier research by the company demonstrated that Product R interferes with the expression of a key protein implicated in the development of cervical cancer (the product of the E7 gene of HPV subtype 18).
 
 Writes Dr. Hirschman, ``These results indicate that Product R may be useful in the treatment of disseminated human papilloma virus infection and in inhibiting the development of cervical cancer. Indeed, these preliminary clinical results suggest that Product R may be an effective non-toxic drug for both systemic and topical therapy of disseminated HPV infection in people with AIDS.''
