Recent Hiv Infection

AbstractBackgroundEarly diagnosis is crucial in securing optimal outcomes in the HIV care cascade. Recent HIV infection (RHI) serves as an indicator of early detection in the course of HIV infection. Surveillance of RHI is important in uncovering at-risk groups in which HIV transmission is ongoing. The study objectives are to estimate the proportion of RHI among persons newly-diagnosed in 2013–2017, and to elucidate epidemiological factors associated with RHI in Singapore.MethodsAs part of the National HIV Molecular Surveillance Programme, residual plasma samples of treatment-naïve HIV-1 positive individuals were tested using the biotinylated peptide-capture enzyme immunoassay with a cutoff of normalized optical density ≤ 0.8 for evidence of RHI. A recent infection testing algorithm was applied for the classification of RHI. We identified risk factors associated with RHI using logistic regression analyses.ResultsA total of 701 newly-diagnosed HIV-infected persons were included in the study. The median age at HIV diagnosis was 38 years (interquartile range, 28–51). The majority were men (94.2%), and sexual route was the predominant mode of HIV transmission (98.3%). Overall, 133/701 (19.0, 95% confidence interval [CI] 16.2–22.0%) were classified as RHI. The proportions of RHI in 2015 (31.1%) and 2017 (31.0%) were significantly higher than in 2014 (11.2%). A significantly higher proportion of men having sex with men (23.4, 95% CI 19.6–27.6%) had RHI compared with heterosexual men (11.1, 95% CI 7.6–15.9%). Independent factors associated with RHI were: age 15–24 years (adjusted odds ratio [aOR] 4.18, 95% CI 1.69–10.31) compared with ≥55 years; HIV diagnosis in 2015 (aOR 2.36, 95% CI 1.25–4.46) and 2017 (aOR 2.52, 95% CI 1.32–4.80) compared with 2013–2014; detection via voluntary testing (aOR 1.91, 95% CI 1.07–3.43) compared with medical care; and self-reported history of HIV test(s) prior to diagnosis (aOR 1.72, 95% CI 1.06–2.81).ConclusionAlthough there appears to be an increasing trend towards early diagnosis, persons with RHI remain a minority in Singapore. The strong associations observed between modifiable behaviors (voluntary testing and HIV testing history) and RHI highlight the importance of increasing the accessibility to HIV testing for at-risk groups.

We sought to describe the prevalence, trends and factors associated with late diagnosis of HIV infection between 2001 and 2008 in Catalonia, Spain. Adults over 13 years of age with available CD4 cell counts, who were notified to the Catalonia Voluntary HIV Surveillance System between January 2001 and December 2008, were included in the study. Late presentation for HIV infection was defined as a CD4 cell count <350 cells/μL or with an AIDS-defining condition at presentation. Multivariable logistic regression was used to identify factors independently associated with late diagnosis of HIV. Of the 4651 newly diagnosed HIV-infected individuals with available CD4 counts, 2598 (55.9%) were diagnosed late. The proportion of people with a late diagnosis decreased from 60.4% in 2001 to 50% in 2008, a significant trend ( P < 0.001). Older age, male gender, foreign birth, heterosexuality and injecting drug use were independent risk factors for late diagnosis. Strategies to actively promote HIV testing to populations at risk of late diagnosis of HIV or those never attending health systems should be implemented.

This study used data on currently married and cohabiting men aged 15 to 64 years from the 2003 Nigeria Demographic and Health Survey to examine the prevalence of and factors associated with extramarital sex. The results show that 16% engaged in extramarital sex in the 12 months preceding the survey and had an average of 1.82 partners. The results also show statistically significant association between extramarital sex and ethnicity, religion, age, age at sexual debut, education, occupation, and place of residence. Based on the study results, it could be concluded that significant proportions of Nigerians are exposed to HIV infection through extramarital sex. A fundamental behavioral change expected in the era of HIV/AIDS is the inculcation of marital fidelity and emotional bonding between marital partners. The promotion of condom use among married couples should be intensified to protect women, a large number of whom are exposed to HIV infection from their spouses who engage in unprotected extramarital sex. And, because of gender-based power imbalances within the family, a large number of the women are unable to negotiate consistent condom use by their partners.

Background: Despite the high availability of individual-level data of infants accessing HIV DNA polymerase chain reaction (DNA-PCR) testing service, there has been little in-depth analysis of such data. Therefore, we describe spatial and temporal trends in risk of HIV infection among Malawi HIV-exposed infants (HEI) with DNA-PCR HIV test result from 2013 to 2020. Methods: This is an implementation study using routinely collected patient-level HIV DNA-PCR test result data extracted from the national Laboratory Management Information System database managed by the Department of HIV/AIDS between 1 January 2013 and 30 June 2020. We calculated frequencies, proportions and odds ratios (OR) with their associated 95% confidence intervals (95%CI). We performed a random-effects logistic regression to determine the risk factors associated with HIV infection in infants, controlling for the spatial autocorrelation between districts and adjusting for other variables. Results: We evaluated 255,229 HEI across 750 facilities in 28 districts. The overall risk of HIV infection among all tested HEI between 2013 and 2020 was 7.2% (95%CI: 7.1-7.3). We observed a decreasing trend in the proportion of HEI that tested HIV positive from 7.0% (95%CI: 6.6-7.4) in 2013 to 5.7% (95%CI: 5.4-5.9) in 2015 followed by an increase to 9.9% (95%CI: 9.6-10.2) in 2017 and then a decreasing trend to 4.2% (95%CI: 3.7-4.6) in 2020. The risk of HIV infection increased by age of the HEI. There was spatial heterogeneity of HIV prevalence between districts of Malawi. Conclusion: We summarised spatial and temporal trends of risk of HIV infection amongst HEI in Malawi between 2013 and 2020. There is need for further strengthening of EID program to ensure that all the HEI are enrolled in care by eight weeks of age in order to further reduce mother-to-child transmission of HIV.

Homeless Men

Homeless men present high vulnerability to HIV infection, mainly due to sexual risk behaviors and substance use. The objective was to estimate the prevalence of HIV infection, risk behaviors and substance use in homeless men. A cross-sectional study was conducted in 481 homeless men recruited in four therapeutic communities in the Goiás State, Central Brazil. All were interviewed about sociodemographic characteristics, substance use, and risk behaviors. Furthermore, all were tested for HIV. Poisson regression was used to verify factors associated with HIV infection. HIV prevalence was 1.24% (95.0% CI: 0.57 to 2.69%). Previous HIV testing (adjusted prevalence ratio [APR]: 10.0; 95.0% CI: 1.86–55.8) and years of education (APR: 0.76; 95.0% CI: 0.60–0.97) were factors associated with HIV infection. Participants had high rates of hazardous alcohol use and illicit drug use. The prevalence of HIV infection among homeless men was higher than that found in the Brazilian male population and we identified a high rate of risk behaviors for HIV among the homeless men investigated. Thus, it is necessary to expand HIV prevention measures in Brazil, such as health education, condom availability, regular HIV testing and increased testing coverage in this population, and treatment for alcohol and/or illicit drug dependence/abuse.
