RESUMO

The progression of AIDS depends on the complex host and virus interactions. The most important disease progression hallmarks are immune activation and apoptosis. In this study, we address the prevalence of polymorphisms related to proinflammatory and apoptotic genes, such as IFNG (+874T/A), TNF (308G/A), IL6 (-174G/C), IL8 (-251A/T), FAS (-670A/G), and FASL (-124A/G) in 160 ethnically mixed HIV-1-infected patients from multicentre cohorts with different clinical outcomes (13 elite controllers [EC], 66 slow long-term non-progressors [LTNPs], and 81 progressors [P]). The genotyping was accomplished by TaqMan-qPCR. Among all the polymorphisms analyzed in the cytokines, the IL6 -174G/C polymorphism showed a higher frequency of GG genotype in the LTNP and LTNP+EC groups as compared to the P group. Moreover, there was a significantly higher frequency of the G allele in the LTNP and LTNP+EC groups as compared to the P group. On the other hand, the levels of CD4+ T lymphocytes were higher among individuals showing the AA and AG genotypes for the FASL -124A/G polymorphism as compared to the GG genotype. Furthermore, the AG and AA genotypes were more frequent, as compared to the GG genotype, in individuals showing a lower viral load. In contrast, for the FAS -670A/G polymorphism, a significantly higher viral load was observed in individuals with the AG genotype as compared to the GG genotype. In conclusion, we found three genetic allelic variants of the IL6 -174G/C, FASL -124A/G, and FAS -670A/G polymorphisms that were related to disease progression and immunological and virological markers in cohorts of HIV-1-positive ethnically mixed patients.

RESUMO

OBJECTIVE: To determine TB knowledge and misconceptions/myths amongst HIV positive and negative adults using Demographic Health Survey data from Lesotho, Malawi, Namibia and Zambia. RESULTS: Overall 97% (n = 58,107) of both male and female respondents irrespective of their HIV status had heard of tuberculosis out of whom 82.6% knew that it can be cured. Knowledge that TB is spread in air when coughing or sneezing was 73.8%. Significantly higher proportions of HIV positive men and women than their HIV negative counterparts, had ever heard about TB, knew that it is transmitted through air when coughing and sneezing and also that it can be cured. However interestingly, significantly higher proportions of HIV positive men and women, than their HIV negative counterparts, had the misconception that TB is spread through sharing utensils or would overall say they did not know how it is spread. TB knowledge was significantly higher among individuals who are less than 26 years of age compared to those who were older.

RESUMO

Objective: To understand prevalence and transmission of transmitted drug resistance (TDR) among HIV infected men who have sex with men (MSM) in Tianjin from 2014 to 2017. Methods: A total of 225 blood samples were collected from HIV infected MSM in Tianjin from 2014 to 2017. Pol gene fragments were obtained by viral RNA extraction and nested PCR amplification. Phylogenetic and drug resistance analyses were conducted. Results: A total of 205 samples were successfully sequenced and analyzed. Based on pol sequences, 53.2% (109/205), 28.8% (59/205), 10.2% (21/205), 4.9% (10/205) and 2.9% (6/205) of the samples were positive for HIV subtypes CRF01_AE, CRF07_BC, B, CRF55_01B and unique recombinant forms (URFs). Twenty transmission clusters, including 75 sequences, were identified and 62.5% (10/16) of sequences with TDR were in 5 clusters. The prevalence of TDR was 7.8% between 2014 and 2017. The annual prevalence rate increased from 3.9% (2/51) in 2014, 5.7% (3/53) in 2015, 9.6% (5/52) in 2016 to 12.2%(6/49) in 2017, the difference was not significant (χ(2)=2.504, P=0.127). CRF01_AE and B strains had high TDR prevalence (3.4%, 7/205) and (2.9%, 6/205), respectively. The TDR mutation was mainly NNRTIs, the TDR prevalence was 6.3% (13/205). In contract, the TDR prevalence of NRTIs and PIs were 1.5% (3/205) and 1.0% (2/205) respectively. Conclusion: Results from this study suggested that the prevalence of HIV-1 TDR strains in MSM was serious in Tianjin. It is necessary to take effective prevention and control measures.

RESUMO

Despite the high HIV incidence and prevalence among black men who have sex with men (BMSM), little research has examined partner characteristics, partner seeking venue, sexual position, substance use, and sexual risk behavior at the sex event-level among BMSM. Using the baseline data from a multi-site study of 807 BMSM stratified by their HIV status, the goal of this study was to conduct a detailed event-level analysis of 1577 male anal sex events to assess the factors associated with condomless anal intercourse (CLAI) with a HIV-discordant or HIV status-unknown partner. We found CLAI with an HIV-discordant or unknown HIV status partner among HIV-negative BMSM was negatively associated with having sex with a main partner, and was positively associated with taking both receptive and insertive sexual positions during sex. As compared to a sex partner met at bar, night club or dance club, HIV-positive BMSM were less likely to engage in CLAI with HIV-discordant and unknown HIV status partner met at party or friend's house or at community organizations. HIV-positive BMSM had lower odds of engaging in CLAI with HIV-discordant and unknown HIV status partner if they had insertive sexual position or both receptive and insertive sexual positions. These results underscore the importance of delineating unique sex event-level factors associated with sexual risk behavior depending on individuals' HIV status. Our findings suggest event-level partner characteristics, sexual position, and partner seeking venues may contribute to disparities in HIV incidence.

RESUMO

BACKGROUND: Adolescents living with HIV face challenges, such as disclosure of HIV status, adherence to antiretroviral therapy, mental health, and sexual and reproductive health (SRH). These challenges affect their future quality of life. However, little evidence is available on their sexual behaviors and SRH needs in Zambia. This study aimed at assessing their sexual behaviors and SRH needs and identifying factors associated with marriage concerns and a desire to have children. METHODS: This cross-sectional study was conducted at the University Teaching Hospital from April to July 2014. We recruited 200 adolescents aged 15-19 years who were aware of their HIV-positive status. We collected data on their first and recent sexual behavior, concerns about marriage, and desire to have children. We used the Generalized Linear Model to identify factors associated with having concerns about marriage and desire to have children. We performed thematic analysis with open-ended data to determine their perceptions about marriage and having children in the future. RESULTS: Out of 175 studied adolescents, 20.6% had experienced sexual intercourse, and only 44.4% used condoms during the first intercourse. Forty-eight percent had concerns about marriage, and 87.4% desired to have children. Marriage-related concerns were high among those who desired to have children (adjusted relative risk [ARR] = 2.51, 95% CI = 1.02 to 6.14). Adolescents who had completed secondary school were more likely to desire to have children (ARR = 1.35, 95% CI = 1.07 to 1.71). Adolescents who had lost both parents were less likely to want children (ARR = 0.80, 95% CI = 0.68 to 0.95). Thematic analysis identified that major concerns about future marriage were fear of disclosing HIV status to partners and risk of infecting partners and/or children. The reasons for their willingness to have children were the desire to be a parent, having children as family assets, a human right, and a source of love and happiness. CONCLUSIONS: Zambian adolescents living with HIV are at risk of engaging in risky sexual relationships and have difficulties in meeting needs of SRH. HIV care service must respond to a wide range of needs.

RESUMO

This study examined the role of stress-related growth as a mediator of the associations between spirituality, religiosity, and feelings of happiness and sadness in a sample of 178 HIV-positive Indian adults. Results indicated that spirituality, but not religiosity, was associated with feelings of happiness and sadness. Subsequent mediation analyses indicated that stress-related growth fully mediated the relationships involving spirituality and feelings of happiness and sadness. Overall, our findings point to the importance of facilitating greater spiritual development among HIV-positive Indians, as well as promoting strategies that help them develop and apply stress-related growth coping methods in their lives.

RESUMO

Objective: To understand the characteristics and dynamic of HIV-1 subtype distribution in men who have sex with men (MSM) in Guangzhou between 2008 and 2015. Methods: HIV-1 RNAs were extracted from serum samples of the individuals newly diagnosed with HIV-1 infection among MSM living in Guangzhou between 2008 and 2015. The pol gene segments of HIV-1 genome from these RNA samples were amplified by nested reverse transcription polymerase chain reaction (nested-PCR) and were sequenced. Subsequently, the phylogenetic tree was reconstructed using pol sequences of samples and references together and the subtype of HIV-1 was determined. The distributions of HIV-1 subtypes detected in MSM with different demographic characteristics in different years were compared. Results: A total of 2 210 pol gene segments were successfully obtained from 2 473 serum samples of the MSM. The average age of 2 210 MSM was 30.19 years with standard deviation of 8.22 years, the unmarried MSM and those in Han ethnic group accounted for 73.39% and 90.81%, respectively. The proportion of subtype CRF07_BC (38.10%) was highest, followed by CRF01_AE (34.84%), CRF55_01B (14.62%), B (6.06%), URFs (3.58%), CRF59_01B (2.17%) and other subtypes (0.63%). The annual proportions of subtype B (P=0.000, 99%CI:0.000-0.000), CRF07_BC (χ(2)=14.965, P=0.036), CRF55_01B (χ(2)=18.161, P=0.011) and URFs (P=0.001, 99% CI: 0.000-0.001) were significantly different. The proportion of subtype B showed a gradual decrease from 14.08% to 4.33% (P=0.000, 99%CI: 0.000-0.000), while the proportion of URFs rapidly increased from 0% to 6.40% (P=0.000, 99% CI: 0.000-0.000). The rate of URFs was significantly higher in farmers and migrant workers than in other groups (P=0.017, 99%CI: 0.014- 0.020) and the rate of URFs was higher in individuals who had multi sexual partners (χ(2)=5.733, P=0.017). Conclusions: CRF07_BC and CRF01_AE were the predominant HIV-1 subtypes and multiple subtypes co-circulated among MSM in Guangzhou between 2008 and 2015. The recombinations of HIV-1 continue to occur in MSM. Strengthening behavioral intervention for farmers, migrant workers and individuals who have multi sexual partners has the important epidemiological significance against the emerging and circulating of the novel recombinant virus among MSM in Guangzhou.

RESUMO

The knowledge and perceptions of cervical cancer among HIV negative and positive women, aged 25-49 years, from rural and urban locations in Zambia was systematically accessed in this study to determine any differences. Data were coded and analyzed using NVivo software. Compared to HIV negative women, HIV positive women had more accurate information about cervical cancer. They were more likely to cite male circumcision as the best approach to cervical cancer prevention. HPV infection was more commonly mentioned as a risk factor among HIV positive women. However, HIV positive women displayed little knowledge about HPV being the major cause of cervical cancer. Among HIV positive women, lack of time was the major screening barrier cited while HIV negative women mentioned being symptomatic as a determinant for early detection. Compared to rural residents, urban residents cited a wider range of cervical cancer information sources, including media and workplace although all of the participants who stated that they had no knowledge of cervical cancer were urban residents. Overall, knowledge and perceptions of cervical cancer among study participants was high, although differences exist between subgroups. Sharing accurate and standardized information on cervical cancer would improve participation in cervical cancer screening services.

RESUMO

OBJECTIVE: The objective of this study was to assess the short-term effects of Gundo-So-a program aimed at empowering Malian women living with HIV (WLHIV) regarding serostatus disclosure management. METHODS: A pre-experimental study with two measures (one week before and four weeks after Gundo-So) was carried out. A 35-item questionnaire was administered to a convenience sample of 210 WLHIV. Six outcomes were considered: ability to decide whether or not to disclose HIV status, self-efficacy to keep HIV status a secret, self-efficacy to disclose HIV status, feeling crushed by the weight of secrecy, perceived physical health, and perceived psychological health. For each outcome, temporal changes associated with the intervention were assessed using linear regressions with random intercepts. RESULTS: Statistically significant change was observed for all six outcomes between the pre- and post-intervention measures. Furthermore, several variables were associated with the baseline levels of the outcomes and the intervention effect. CONCLUSION: The results suggest that Gundo-So empowers Malian WLHIV with regard to serostatus disclosure management, thus improving their perceived physical and psychological health. PRACTICAL IMPLICATIONS: These results highlight the need for programs to empower WLHIV regarding serostatus disclosure, so that WLHIV can make free and informed decisions regarding serostatus disclosure.

RESUMO

OBJECTIVES: We sought to calculate HIV incidence in a retrospective cohort of young (13-29 years old) black men who have sex with men (YBMSM) accessing repeated HIV-antibody testing in a mid-size city in the USA. METHODS: We aggregated site-specific HIV-antibody testing results from the project's inception among YBMSM who received an initial negative result and accessed at least one additional HIV-antibody test. From these data, we assessed number of seroconversions and person-years and calculated HIV incidence using a mid-P exact test to estimate 95% CIs. RESULTS: Five seroconversions were documented over 42.3 person-years (the mean age at first onsite test: 19.7 years), resulting in an HIV incidence rate of 11.8% (95% CI 4.3% to 26.2%). The mean age at seroconversion was 20.4 (±3.0) years. CONCLUSIONS: Even in mid-size cities with low HIV prevalence rates in the general population, HIV incidence among YBMSM may be high. Community-based HIV-antibody testing organisations serving YBMSM should be encouraged and trained to track repeated HIV testing and calculate HIV incidence rates. Increased resources should be deployed to develop and encourage regular HIV testing in community health sites serving YBMSM.

RESUMO

Previous research has reported an association between depressive symptoms and sexual risk behavior. The purpose of this study was to explore whether gender moderates this association in a sample of HIV-positive African-Americans. Participants (N = 93) self-reported depressive symptoms (Center for Epidemiological Studies-Depression Scale; CES-D), and sexual risk behavior for the past 4 months. Analyses revealed that the depressive symptoms-by-gender interaction was associated with condomless sex and substance use proximal to sex. When analyses were stratified by gender, depressive symptoms were associated with condomless sex and frequency of substance use only for women. We conclude that depressive symptoms may be a more powerful sexual risk factor among women relative to men.

RESUMO

Objective: To understand the characteristic of subtype distribution among foreigners who were living with HIV-1, in Guangzhou. Methods: HIV-1 RNAs were extracted from 114 serum specimens in foreigners diagnosed with HIV-1 infections between 2008 and 2010, and in 2015. Partial pol gene of HIV-1 genome from these RNA samples were amplified by nested reverse transcription polymerase chain reaction (nested-PCR) with nucleotide sequenced. Subsequently, phylogenetic tree was reconstructed using the pol sequences of samples and references. Results: Among all the 114 samples, 57.9% were from males and 42.1% from females, with an average age as 35.21 years old and the standard deviation as 9.63 years. A total of 6.8% of the samples were from Africans. The top three subtypes were identified as CRF02_AG, subtype G and subtype C, accounted for 30.7%, 14.9% and 12.3% respectively. Compared with samples gathered from 2008 to 2010, the proportions of subtype A1 and CRF01_AE significantly increased, while the other subtypes significantly decreased in 2015 (χ(2)=37.570; P=0.013, 99% CI: 0.010-0.016). Proportions of CRF01_AE and subtype G among males outnumbered the females but the proportions of subtype A1, CRF02_AG and URF among females appeared the other way round (χ(2)=15.528; P=0.029, 99%CI: 0.024-0.033). Proportions of CRF02_AG and subtype G among HIV-1 positive Africans were larger than those from other Southeast Asian countries or areas, However, the proportion of CRF01_AE among HIV-1 positive patients from Southeast Asian countries was higher than those patients from other areas (χ(2)=39.399; P=0.009, 99% CI: 0.006-0.011). The rates of resistance to any drug of protease inhibitors (PIs), reverse transcriptase inhibitors (RTIs), as well as to PIs, NRTIs, and NNRTIs alone, were 21.9%, 12.3%, 6.1% and 7.0%, respectively. One of nine CRF01_AEs from the HIV-1 positive patients were found closely clustered in those phylogenetic tree (bootstrap=0.855) samples, collected from local patients in Guangzhou. Conclusions: Our findings showed that these foreign subtypes had been spread to the natives, more from the Africans than from the other areas, in Guangzhou. These types of viruses were different from the strains identified locally, suggesting that they might have been brought in by foreigners living with HIV-1, in Guangzhou. Programs related to care, support and behavioral intervention for HIV positive foreigners living in Guangzhou, should be strengthened.

RESUMO

BACKGROUND: The African, Caribbean and Black communities have been found to be reluctant to participate in health research in North America. This is partly attributed to historical experiences as well as their cultural beliefs. Cultural beliefs about the uses of breast milk/fluids could further hinder the participation of African, Caribbean, and Black communities in research involving the collection of breast milk/fluids samples. METHODS: We conducted 17 in-depth interviews and three group interviews (n = 10) with HIV+ African, Caribbean and Black women living in Ontario, Canada to explore their cultural beliefs about breast milk/fluids and their acceptance of participating in research that involves the provision of breast fluid samples. STUDY DESIGN: Qualitative study involving in-depth interviews. RESULTS: Our respondents believed that breast milk/fluids should be used for infant feeding and for curative purposes for a variety of children's health ailments as well as ailments experienced by other family members. The cultural belief that breast milk/fluids could be used to bewitch the baby and mother and the perception that it is intrusive (equating breast milk/fluids research to DNA testing), could prevent African, Caribbean and Black women from participating in research involving the collection of breast milk/fluids. Despite these fears, some respondents expressed that they would participate if the research results would benefit them directly, for example, by finding a cure for HIV, enabling HIV+ mothers to breastfeed, or contributing to developing new drugs or vaccines for HIV. Women's recommendations to facilitate successful recruitment included giving incentives to participants, and employing a recruiter who was trustworthy, informed, and culturally sensitive. CONCLUSION: Cultural beliefs could present barriers to recruitment and participation of Africa, Caribbean and Black communities in health research involving breast milk/fluid samples. Successful recruitment for future studies would necessitate researchers to be culturally aware of the beliefs held by African, Caribbean and Black women, to build trust, and use an appropriate recruiter. While the findings relate to breast milk/fluids, the suggested recommendations for facilitating recruitment of research participants from these communities may be useful to consider when recruiting ethnically and culturally similar participants for research involving biological samples.

RESUMO

OBJECTIVE: Historically marginalized groups are likely to be exposed to social adversity, which predicts important mental health outcomes (e.g., depression). Despite the well-established relationship between adversity and poor health, few studies have examined how adversity differentially predicts mental health among people living with multiple, co-occurring marginalized identities or statuses. The current study fills this gap by examining whether relationships between social adversity and depressive symptoms differed between those living with or without a stigmatized disease (i.e., HIV) and/or marginalized racial/ethnic identity (i.e., African American). METHOD: A community sample of men and women (N = 149) completed questionnaires assessing demographics and depressive symptoms. Additionally, a composite index of social adversity was derived from measures of perceived discrimination, socioeconomic status, financial restriction to receiving medical care, and perceived neighborhood characteristics. Multiple regression was used to test whether relationships between adversity and depressive symptoms differed as a function of HIV status and racial/ethnic identity. RESULTS: A significant 3-way interaction between social adversity, HIV status, and racial/ethnic identity indicated that there was a direct relationship between adversity and depressive symptoms for HIV-positive (HIV+) African Americans but not for HIV-negative (HIV-) African Americans, HIV+ Caucasians, or HIV- Caucasians. Further, HIV+ African Americans evidenced a significantly greater relationship between adversity and depressive symptoms compared with HIV- African Americans, but not compared with other groups. CONCLUSIONS: The findings suggest that HIV+ African Americans may be at risk for higher depressive symptoms amid adversity, highlighting the importance of evaluating intersectional identities/statuses in the context of mental health.

RESUMO

Black gay and bisexual young men carry a disproportionate burden of HIV in the United States. This study explored Black gay and bisexual young men living with HIV's identification and interpretation of race-specific cultural messages regarding substance use, sexual activity, and condom use. A total of 36 Black gay and bisexual young men living with HIV (ages 16-24, mean = 20.6 years) from four geographically diverse regions of the United States participated in qualitative in-depth interviews. Results from this study elucidate the ways in which these young men interpret various forms of race-specific cultural messages and experiences regarding substance use, sexual activity, and condom use. Participants discussed cultural messages and experiences promoting and discouraging condoms and substance use. Regarding sexual activity, only messages and experiences promoting sex were reported. Across all three categories, messages and experiences promoting risk were predominant. Data further revealed that socially transmitted cultural messages received by young men emanated from multiple sources, such as family, peers, sexual partners, community/neighborhood, and the broader society. Race-specific cultural messages and experiences should be addressed in interventions for this population, and programs should assist young men in developing a critical consciousness regarding these messages and experiences in order to promote health and well-being.

RESUMO

Men who have sex with men (MSM), particularly racial/ethnic minority MSM, are disproportionately affected by HIV in the United States and Texas. Bareback sex or condomless anal intercourse (CAI) can be a high HIV risk behavior. Despite this, a majority of MSM continues to engage in barebacking. Research suggests racial/ethnic differences in barebacking exist; however, these conclusions remain unclear due to insufficient sample sizes to compare racial/ethnic groups. Our cross-sectional correlational design explores barebacking correlates (substance use during sex, safe sex fatigue, and optimistic HIV treatment beliefs) within and between racial/ethnic groups among 366 MSM. Regression models are significant for Latino and African-American MSM alone and for all MSM combined, though not significant for European-American and Other Race/Ethnicity MSM alone. Our findings suggest motivations and behaviors underlying barebacking among MSM vary by racial/ethnic membership with clinical implications for informing culturally sensitive HIV interventions and prevention programs for target racial/ethnic groups.

RESUMO

BACKGROUND: Describe dual contraceptive method use and the intention to become pregnant of people living with HIV (PLHIV) and their partners in Thailand. METHODS: From January 2008-March 2009, we systematically selected a cohort of PLHIV from PLHIV seeking care at five tertiary care hospitals and one community hospital to complete a questionnaire assessing sexual activity, intention to become pregnant, and contraceptive practices at baseline and 12 months after enrollment. Participants received short family planning messages every 2-3 months to promote the use of dual contraceptives and were offered family planning services. RESULTS: A total of 1,388 PLHIV enrolled, their median age was 37 years (IQR 33-43), 898 (64.7%) had a steady partner, and 737 (53.1%) were male. Among those with a steady partner, 862 (96.0%) did not intend to become pregnant; 709 (82.3%) had sex during the previous 3 months, 683 (96.3%) used at least one contraceptive method, and 202 (29.6%) used dual contraceptive methods. Of the 317 PLHIV who used a single contraceptive method at baseline, 66 (20.8%) reported using dual methods at 12 months. Participants at two tertiary care hospitals where coordinators facilitated PLHIV referral between HIV and OB/GYN clinics were more likely than participants at the other hospitals to change from single method to dual method (p ≤ 0.03). CONCLUSION: Few PLHIV in this study intended to become pregnant; however, only one-fourth used dual contraceptive methods. Integrating an assessment of the intention to become pregnant and strengthening the PLHIV referral systems in family planning services may contribute to higher rates of dual contraceptive use.

RESUMO

Despite the widespread dissemination of HIV information through public awareness campaigns in Mali, disclosing seropositivity to one's steady sexual partner (SSP) remains difficult for people living with HIV (PLHIV). Disclosure is a public health concern with serious implications and is also strongly linked to the quality of life of PLHIV. This study aimed to analyse factors associated with voluntary HIV disclosure to one's SSP, using a community-based cross-sectional study on 300 adult PLHIV in contact with a Malian community-based organization working in the field of AIDS response. A 125-item questionnaire was administered by trained personnel to study participants between May and October 2011. Analysis was restricted to the 219 participants who both reported having a SSP and answered to the question on disclosure to their SSP. A weighted multivariate logistic regression was used to determine variables independently associated with disclosure. In total, 161 participants (73%) reported HIV disclosure to their SSP. Having children (odds ratio [95% confidence interval]: 4.52 [1.84-11.12]), being accompanied to the survey site (3.66 [1.00-13.33]), knowing others who had publicly declared their seropositivity (3.12 [1.59-6.12]), having higher self-esteem (1.55 [1.09-2.19]) and using means other than anti-retroviral treatment to treat HIV (0.33 [0.11-1.00]) were independently associated with disclosure. This study identified several factors that should be considered for the design of interventions aimed at facilitating disclosure if/when desired in this cultural context.
