In addressing a press conference this summer at the United Nations High-Level Meeting on AIDS, Dr Anthony Fauci of the NIH commented on the “40,000 to 52,000 new infections each year” occurring in the United States.

Five years ago, the International Agency for Research on Cancer (IARC) conducted a case-control study in 9 sites (Italy, Spain, Northern Ireland, Poland, India, Cuba, Canada, Australia, and Sudan) of 1415 participants with cancer of the oral cavity and 255 with oropharyngeal carcinoma.1 Markers for human papillomavirus (HPV) infection were evaluated, including antibodies against HPV16 E6 and E7 proteins, which are common in cervical cancer, and HPV DNA in biopsy samples, detected by polymerase chain reaction assay.

A 40-year-old homosexual man with CDC class B3 HIV infection presented to our clinic complaining of worsening right hip pain. HIV infection had been diagnosed in 1995. His most recent CD4+ cell count was 167/µL, and his HIV RNA level was suppressed while he was receiving antiretroviral therapy consisting of emtricitabine/tenofovir fixed-dose combination, efavirenz, and ritonavir-boosted atazanavir.

Kaposi sarcoma (KS), AIDS-related non-Hodgkin lymphoma (AIDS-NHL), and anal squamous cell carcinoma/anal intraepithelial neoplasia (SCC/AIN) are malignancies that commonly involve the GI tract in patients who have HIV/AIDS.1 Oncogenic viruses have been implicated in the etiology of each of these neoplasms-specifically, human herpes virus 8 (HHV8) in KS, Epstein-Barr virus (EBV) in AIDS-NHL, and human papillomavirus in SCC/AIN.

Primary HIV infection refers to the earliest stages of infection, or the interval from initial infection to seroconversion (when antibody to HIV is detectable). During this stage, many patients have symptoms of acute HIV seroconversion illness, are viremic with very high HIV RNA levels, and have negative or indeterminate findings on HIV antibody tests.

In the early years of the HIV/AIDS epidemic, the physicians and nurses who provided care to patients with this puzzling and clearly complex infection identified the benefits of specialized knowledge of the virus and management of the symptoms associated with its attack on the immune system.

“It’s a completely different mechanism of action to what we have currently under development and what the field has under development,” said Dr Zeda Rosenberg, IPM’s CEO. “It’s pretty early in the life cycle for HIV. Most of us feel that for a microbicide to be really effective, it has to get at the infection in its earliest time points.”

The 15th Conference on Retroviruses and Opportunistic Infections (15th CROI) was held in Boston from February 3 to 6, 2008. There were more than 1000 oral and poster presentations at this conference and, as is usually the case, some were quite important.
