METHODS: A total of 1075 young adult respondents aged 15-24 years participated in this survey. The response rate was 82.2%.
RESULTS: The data indicated that HIV/AIDS knowledge among the respondents was moderate, with a mean knowledge score of 20.1 out of 32 points. The great majority had adequate knowledge of the major routes of HIV transmission, but fewer were aware of other modes of transmission, such as tattooing and piercing, sharing personal items, and breast-feeding from an infected mother. The great majority knew that HIV is not transmitted by mosquito bites, sharing meals, casual contact, and using public swimming pools and toilets.
CONCLUSIONS: Misconceptions about HIV/AIDS exist although generally knowledge on HIV/AIDS transmission and prevention was accurate. Education and intervention programs are needed to increase the level of knowledge and awareness of HIV/AIDS. The findings have important implications for the development of primary HIV/AIDS prevention programs for young adults in Malaysia.
METHOD: In this cross-sectional study, HIV-infected participants receiving suppressive ART for a minimum of 12 months were recruited from the University Malaya Medical Centre (UMMC), Malaysia. Stored plasma was analyzed for CMV, VZV, HSV-1 and HSV-2 IgG antibody levels, immune activation markers (interleukin-6, interferon-γ, neopterin and sCD14), kynurenine and tryptophan concentrations. The influence of the number of HHV co-infection and K/T ratio on CD4 T-cell recovery was assessed using multivariate Poisson regression.
RESULTS: A total of 232 HIV-infected participants were recruited and all participants were seropositive for at least one HHV; 96.1% with CMV, 86.6% with VZV, 70.7% with HSV-1 and 53.9% with HSV-2. K/T ratio had a significant positive correlation with CMV (rho = 0.205, p = 0.002), VZV (rho = 0.173, p = 0.009) and a tendency with HSV-2 (rho = 0.120, p = 0.070), with CMV antibody titer demonstrating the strongest modulating effect on K/T ratio among the four HHVs assessed in SOM analysis. In multivariate analysis, higher K/T ratio (p = 0.03) and increasing number of HHV co-infections (p<0.001) were independently associated with poorer CD4 T-cell recovery following 12 months of ART initiation.
CONCLUSION: Multiple HHV co-infections are common among ART-treated HIV-infected participants in the developing country setting and associated with persistent immune activation and poorer CD4 T-cell recovery.
METHODS: Patients testing HBs antigen (Ag) or HCV antibody (Ab) positive within enrollment into TAHOD were considered HBV or HCV co-infected. Factors associated with HBV and/or HCV co-infection were assessed by logistic regression models. Factors associated with post-ART HIV immunological response (CD4 change after six months) and virological response (HIV RNA <400 copies/ml after 12 months) were also determined. Survival was assessed by the Kaplan-Meier method and log rank test.
RESULTS: A total of 7,455 subjects were recruited by December 2012. Of patients tested, 591/5656 (10.4%) were HBsAg positive, 794/5215 (15.2%) were HCVAb positive, and 88/4966 (1.8%) were positive for both markers. In multivariate analysis, HCV co-infection, age, route of HIV infection, baseline CD4 count, baseline HIV RNA, and HIV-1 subtype were associated with immunological recovery. Age, route of HIV infection, baseline CD4 count, baseline HIV RNA, ART regimen, prior ART and HIV-1 subtype, but not HBV or HCV co-infection, affected HIV RNA suppression. Risk factors affecting mortality included HCV co-infection, age, CDC stage, baseline CD4 count, baseline HIV RNA and prior mono/dual ART. Shortest survival was seen in subjects who were both HBV- and HCV-positive.
CONCLUSION: In this Asian cohort of HIV-infected patients, HCV co-infection, but not HBV co-infection, was associated with lower CD4 cell recovery after ART and increased mortality.
METHODS: Baseline assessment of treatment-seeking subjects (n=177) included the Addiction Severity Index; AIDS Risk Inventory; serological tests for HIV, hepatitis B, and hepatitis C; and chest X-ray.
RESULTS: All of the subjects were male; 67.8% were Malays, 28.8% Chinese, and 2.3%. Indian. Subjects had a mean (SD) age of 37.2 (9.1) years and 14.4 (8.5) years of using heroin; 76.3% reported lifetime injection drug use (IDU), and 41.5% reported current IDU; 30 of 156 (19.2%) tested HIV positive, 143 of 159 (89.9%) tested hepatitis C positive, and 25 of 159 (15.7%) had radiological evidence of pulmonary tuberbulosis. Malay subjects had a significantly higher prevalence of current IDU, needle sharing (p<0.01), and HIV infection (p<0.05) compared with Chinese subjects. Lifetime IDU, needle sharing, lack of consistent condom use, and Malay ethnicity were significantly associated with HIV infection.
CONCLUSIONS: The high prevalence of HIV infection among heroin-dependent individuals, in Malaysia supports the important of interventions to reduce the major risk factors for HIV, including IDU, needle sharing, and unprotected sex.
