The prevalent and incident detection of HPV16 is more weakly associated with immune status in HIV-seropositive women than that of other HPV types, suggesting that HPV16 may be better at avoiding the effects of immune surveillance, which could contribute to HPV16's strong association with cervical cancer.

Simple clinical variables, all readily available at the time of hospital admission, can help to differentiate these common pneumonia syndromes in HIV-infected patients. These findings can help to inform clinical decision-making regarding choice of therapy, use of invasive diagnostic procedures, and need for respiratory isolation.

The influence of HIV on sexual activity and functioning presents a unique set of issues. HIV transmissibility, partner disclosure, potential vertical transmission and, for some HIV-infected women, problems associated with illicit drug use, may affect sexuality. Few studies have examined HIV-infected women's sexuality and none have studied the relationship between HIV symptoms, HIV illness stage, quality of life, meaning of illness and sexual functioning. This descriptive study examines sexual activity, sexual functioning and safer sex behavior among 101 HIV-seropositive women. Results indicate that (1) the majority of women continue to be sexually active after testing HIV positive, (2) sexual functioning does not change as a result of HIV disease progression, and (3) few women report that HIV itself caused worsening of their sexual functioning. Those women with better mental health, more positive meaning attributed to life with HIV infection, better quality of life, fewer HIV-related symptoms and who never used injection drugs had higher levels of sexual functioning. Greater focus on sexual functioning as an integral part of clinical assessment is needed. Patterns of sexual behavior among HIV-infected women require continued study as we search for more effective means to prevent secondary HIV transmission.

Injection drug users (IDUs) are the vanguard of the human immunodeficiency virus (HIV) epidemic in Russia. We sought a non-invasive method to estimate a point prevalence of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis and risk behaviours in IDUs attending the syringe exchange programme (SEP) in St Petersburg, Russia. One hundred and one IDUs returning syringes to the St Petersburg SEP were invited to complete a questionnaire requesting demographic, knowledge, and behavioural information, and to provide their syringes for antibody testing. The median age of IDUs was 23 years. Syringe prevalences were: 10.9% for HIV, 78.2% for HCV, 15.8% for HBV, and 6.9% for syphilis. All respondents recognized drug-related risk factors for getting AIDS. Only two-thirds of subjects recognized condoms to prevent sexually transmitted infections and half knew that oil-based lubricants are not appropriate for condoms. The IDU population studied was young and requires additional interventions to encourage safer sexual behaviours.
