Correlates of HIV infection among incarcerated women: implications for improving detection of HIV infection.

The prevalence of HIV infection in correctional settings is several-fold higher than found in community settings. New approaches to identifying HIV infection among prisoners are urgently needed. In order to determine the HIV seroprevalence and to identify the correlates of HIV infection among female prisoners, an anonymous, but linked HIV serosurvey was conducted at Connecticut's sole correctional facility for women (census=1,100). After removing all individual identifiers for inmates' standardized clinical and risk behavior information, data are linked by a third source to blinded HIV-testing information by a third party. This three-step sequential process allows for anonymous HIV testing that can still be linked with deidentified clinical and behavioral data. Of the 3,315 subjects with complete information, 250 (7.5%) were HIV+. Of these, 157 (63%) self-reported being HIV+. Using multiple logistic regression analysis, having sex with a known HIV+ person [adjusted odds ratio (AOR)=9.1] and injection drug use (AOR=6.1) were the most highly correlated risk factors for HIV, whereas leukopenia (AOR=9.4) and hypoalbuminemia (AOR=7.2) were the most significant laboratory markers. Other independent correlates of HIV included self-report of syphilis (AOR=1.9) or genital herpes infection (AOR=2.7) and being Black (AOR=2.1) or Hispanic (AOR=2.2). The prevalence of HIV and HIV-risk behaviors is high among incarcerated women. Existing voluntary HIV counseling and testing programs do not completely target high-risk groups who remain part of the evolving epidemic. Defined demographic, behavioral, and clinical assessments may provide useful information for encouraging targeted counseling and testing. Newer targeted approaches merit further study to determine the effectiveness of this approach. Alternative methods of facilitating more widespread HIV testing, such as saliva tests, rapid serologic tests, and more routine testing in high HIV-prevalence areas should be considered both for clinical and for public health benefits.

Managing HIV/AIDS in correctional settings.

Approximately one quarter of people living with HIV/AIDS in the United States pass through the correctional system, resulting in a burden of infection on the correctional health care system that has challenged correctional and public health officials. The HIV epidemic behind bars results from the high prevalence of HIV risk behaviors among those incarcerated: illicit drug use, untreated mental illness, prostitution, homelessness, and poverty. Challenges to HIV care in correctional settings include management of comorbid conditions, remoteness from HIV care sites, organizational constraints, and access to effective therapies. Despite these challenges, prisoners with HIV have derived considerable benefit from HIV detection and treatment. In order to achieve parity in HIV outcomes among vulnerable populations, effective prison-release programs that incorporate effective case management with effective drug treatment and adherence strategies are required to extend the benefit of highly active antiretroviral therapy as prisoners transition back to community settings.

Developing a directly administered antiretroviral therapy intervention for HIV-infected drug users: implications for program replication.

Directly administered antiretroviral therapy (DAART) is one approach to improving adherence to among human immunodeficiency virus (HIV)-infected drug users. We evaluated the essential features of a community-based DAART intervention in a randomized, controlled trial of DAART versus self-administered therapy. Of the initial 72 subjects, 78% were racial minorities, and 32% were women. Social and medical comorbidities among subjects included homelessness (35% of subjects), lack of interpersonal support (86%), major depression (57%), and alcoholism (36%). At baseline, the median CD4+ cell count was 403 cells/mL and the median HIV-1 RNA load was 146,333 copies/mL (log10 5.31 copies/mL). During the prior 6 months, 33% of subjects had missed a medical appointment, and 47% had visited an emergency department. Although most subjects (67%) preferred to take their own medications, 76% would accept DAART if it were made compulsory. A methadone clinic was the DAART venue acceptable to the fewest subjects (36%), and a mobile syringe-exchange program was acceptable to the most subjects (83%). Adherence was higher for supervised than for unsupervised medication administration (P<.0001), a finding that supports use of daily supervision of once-daily regimens. Moreover, DAART should incorporate enhanced elements such as convenience, flexibility, confidentiality, cues and reminders, responsive pharmacy and medical services, and specialized training for staff.

Effectiveness of antiretroviral therapy among HIV-infected prisoners: reincarceration and the lack of sustained benefit after release to the community.

Responses to highly active antiretroviral therapy (HAART) in correctional settings and their sustained benefit in prisoners after release are currently not known. To examine the human immunodeficiency virus type 1 (HIV-1) RNA level (VL) and CD4 lymphocyte response to HAART during incarceration and upon reentry to the correctional system, we conducted a retrospective cohort study of longitudinally linked demographic, pharmacy, and laboratory data from the Connecticut prison system. During incarceration, the mean CD4 lymphocyte count increased by 74 lymphocytes/ mu L, and the mean VL decreased by 0.93 log10 copies/mL (P<.0001). Fifty-nine percent of the subjects achieved a VL of <400 copies/mL at the end of each incarceration period. For the 27% of subjects who were reincarcerated, the mean CD4 lymphocyte count decreased by 80 lymphocytes/ mu L, and the mean VL increased by 1.14 log10 (P<.0001). Although HAART use resulted in impressive VL and CD4 lymphocyte outcomes during the period of incarceration, recidivism to prison was high and was associated with a poor outcome. More effective community-release programs are needed for incarcerated patients with HIV disease.

Human immunodeficiency virus infection with human granulocytic ehrlichiosis complicated by symptomatic lactic acidosis.

Lactic acidosis has been reported as a complication associated with antiretroviral therapy; in particular, usually with use of nucleoside reverse-transcriptase inhibitors. We describe a human immunodeficiency virus (HIV)-infected patient with a history of lipodystrophy who presented with hepatic insult associated with documented human granulocytic ehrlichiosis (HGE). Despite a normal serum lactate level before the onset of acute coinfection, the patient developed symptomatic hyperlactatemia while receiving appropriate treatment for HGE. To date, this is the first presentation of symptomatic hyperlactatemia in a patient with HIV infection and HGE.
