About PHN and HIV-DSP

PHN is a painful condition affecting sensory nerve fibers. It is a complication of shingles, a second outbreak of the varicella-zoster virus, which initially causes chickenpox. Following an initial infection, some of the virus can remain dormant in nerve cells. Years later, age, illness, stress, medications or other factors that are not well understood can lead to reactivation of the virus. The rash and blisters associated with shingles usually heal within six weeks, but some people continue to experience pain for years thereafter. This pain is known as postherpetic neuralgia. PHN may occur in almost any area, but is especially common on the torso.

According to the Centers for Disease Control, there are approximately 1.0 million cases of shingles in the United States each year, and approximately one in five develop PHN. According to Jain BioPharma, in 2005 there were approximately 500,000 people in the United States living with PHN.

HIV-DSP is caused primarily by three factors: direct activation of cells known as sensory neurons by the HIV virus, the immune system’s fight against the infection, and the drugs administered to treat HIV. Painful HIV-DSP is characterized by significant pain in the feet and hands.

According to Frost & Sullivan, neuropathic pain affects approximately 15% of the HIV infected community. According to the CDC, in 2005 there were 956,000 people in the United States infected with HIV. There are currently no specific treatments approved in the United States or Europe for HIV-DSP.
