High efficacy of lopinavir/r-based second-line antiretroviral treatment after 24 months of follow up at ESTHER/Calmette Hospital in Phnom Penh, Cambodia
<p>Abstract</p> <p>Background</p> <p>The number of patients on second-line highly active antiretroviral therapy (HAART) regimens is increasing in resource-limited settings. We describe the outcomes after 24 months for patients on LPV/r-based second-line regimens followed up by the ESTHER programme in Phnom Penh, Cambodia.</p> <p>Methods</p> <p>Seventy patients who initiated second-line HAART regimens more than 24 months earlier were included, and immuno-virological data analyzed. HIV RNA viral load was determined by real-time RT-PCR. HIV-1 drug resistance was interpreted according to the ANRS algorithm.</p> <p>Results</p> <p>Of the 70 patients, two were lost to follow up, three died and 65 (92.8%) remained on second-line treatment after 24 months of follow up (median duration of treatment: 27.4 months). At switch to second-line, the median CD4 T cell count was 106 cells/mm<sup>3 </sup>and the median viral load was 4.7 Log<sub>10</sub>. Second-line regimens prescribed were ddI/3TC/LPV<sub>/r </sub>(65.7%), ddI/TDF/LPV<sub>/r </sub>(10.0%), ddI/AZT/LPV<sub>/r </sub>(8.6%) and TDF/3TC/LPV<sub>/r </sub>(7.1%). The median CD4 T cell gain was +258 cells/mm<sup>3 </sup>at 24 months (n = 63). After 24 months of follow up, 92.3% (60/65) of the patients presented undetectable viral loads, giving an overall treatment success rate of 85.7% (CI: 75.6- 92.0) in intent-to-treat analysis.</p> <p>Conclusions</p> <p>These data suggest that a LPV<sub>/r</sub>-based second-line regimen is associated with a high rate of virological suppression and immune reconstitution after 24 months of follow up in Cambodia.</p

High prevalence of unhealthy alcohol use and comparison of self-reported alcohol consumption to phosphatidylethanol among women engaged in sex work and their male clients in Cambodia.
BackgroundIn Cambodia, most of the female sex workers (FSW) work in venues where unhealthy alcohol use is ubiquitous and potentially contributing to the HIV epidemic. However, no accurate data exists. We compare self-reported unhealthy alcohol consumption to a biomarker of alcohol intake in Cambodian FSW and male clients, and determine factors associated with unhealthy alcohol use.MethodsA cross-sectional study was conducted among FSW (n=100) and male clients (n=100) in entertainment and sex work venues in Cambodia. Self-reported unhealthy alcohol use (AUDIT-C) was compared to phosphatidylethanol (PEth) positive (≥50ng/ml), a biomarker of alcohol intake. Sociodemographics data was collected. Correlates of self-reported unhealthy alcohol use and PEth positive were determined.ResultsThe prevalence of PEth positive in FSW was 60.0%. Self-reported unhealthy alcohol consumption was reported by 85.0% of the women. Almost all women (95.0%) testing PEth positive also reported unhealthy alcohol use. Prevalence of unhealthy alcohol consumption (self-report and PEth positive) was higher in FSW working in entertainment establishments compared to other sex work venues (p<0.01). Among male clients, 47.0% reported unhealthy alcohol consumption and 42.0% had a PEth positive. However, only 57.1% of male clients with PEth positive reported unhealthy alcohol use.ConclusionsUnhealthy alcohol consumption is prevalent in Cambodian sex work settings. Self-reported unhealthy alcohol use is well reported by FSW, but less by male clients. These findings highlight the urgency of using accurate measures of unhealthy alcohol consumption and integrating this health issue into HIV prevention interventions

Changing behaviors and patterns among Cambodian sex workers: 1997-2003
OBJECTIVE: Identify patterns and behaviors among direct and indirect female sex workers (DFSWs and IDFSWs, respectively) across Cambodia's 5 major cities from 1997 to 2003. METHODS: Interviews with DFSWs and IDFSWs followed random selection from clusters in 5 cities. Individual characteristics and condom use with clients and other partners were assessed in univariate and multivariate analyses. RESULTS: From 1997 to 2003, consistent condom use with clients increased from 53% to 96% among DFSWs and from 30% to 84% among IDFSWs. DFSWs reported staying in their profession longer, had fewer clients per day, stayed longer in each brothel, were in increasingly larger brothels, and were tested more for HIV. For IDFSWs, there were significant changes: more reported practicing commercial sex and testing for HIV. In adjusted models, reported condom use with clients was significantly higher among DFSWs in later survey years (odds ratio [OR], 2.17) and who were never married (OR, 1.69), were in larger brothels (OR, 1.02), and charged more for sex (OR, 1.27), but lower for DFSWs with sweethearts (OR, 0.68) and who reported abnormal vaginal discharge (OR, 0.52). For IDFSWs, in the adjusted models, reported condom use with clients was higher in later years (OR, 1.77) and for those reporting abnormal vaginal discharge (OR, 1.34) and HIV testing (OR, 1.46), and lower for those with sweethearts (OR, 0.49). CONCLUSIONS: From 1997 to 2003, Cambodian direct and indirect sex workers increased their use of condoms each year with commercial as well as noncommercial partners, contributing to the evidence that HIV prevention programs can produce significant changes in risk behaviors

Human papillomavirus knowledge, vaccine acceptance, and vaccine series completion among female entertainment and sex workers in Phnom Penh, Cambodia: the Young Women’s Health Study
Human papillomavirus is a common sexually transmitted infection and the causative agent for cervical cancer, a frequently occurring malignant disease among women in developing countries. We assessed human papillomavirus awareness prior to the delivery of a brief information and education intervention, and human papillomavirus vaccine provision to female entertainment and sex workers (N = 220). At baseline, only 23.6% of women had heard of human papillomavirus. Following the educational intervention, 90% answered all the human papillomavirus knowledge questions correctly. Of 192 participants attending the first quarterly cohort visit where vaccine was offered, 149 (78%) were eligible for vaccination; HIV-positive (n = 32) and pregnant (n = 11) women were excluded. Acceptance of vaccine among eligible women was universal, and 79.2% completed the three-dose vaccination series. Women who reported use of amphetamine-type stimulants had significantly and independently lower odds of vaccine completion (adjusted odds ratio [AOR] 0.24; 95% confidence interval [CI] 0.08, 0.69). New pregnancies also had an impact on vaccine completion: 5.4% (8/149 5.4%) who started the series had to stop due to new pregnancy. Results demonstrate the effectiveness of a simple education intervention designed to increase human papillomavirus knowledge and the feasibility of successful human papillomavirus vaccine in a population that is often difficult to engage in preventive health care
