Analytical methods used in estimating the prevalence of HIV/AIDS from demographic and cross-sectional surveys with missing data: a systematic review. Sero- prevalence studies often have a problem of missing data. Few studies report the proportion of missing data and even fewer describe the methods used to adjust the results for missing data. The objective of this review was to determine the analytical methods used for analysis in HIV surveys with missing data.We searched for population (...) , demographic and cross-sectional surveys of HIV published from January 2000 to April 2018 in Pub Med/Medline, Web of Science core collection, Latin American and Caribbean Sciences Literature, Africa-Wide Information and Scopus, and by reviewing references of included articles. All potential abstracts were imported into Covidence and abstracts screened by two independent reviewers using pre-specified criteria. Disagreements were resolved through discussion. A piloted data extraction tool was used to extract
A systematic review of immunogenicity, clinical efficacy and safety of human papillomavirus vaccines in people living with the humanimmunodeficiencyvirus. The human papillomavirus (HPV) is the most prevalent sexually transmitted infection worldwide. People living with the humanimmunodeficiencyvirus (HIV) are at high risk of HPV infection. This systematic review evaluates the immunogenicity, clinical efficacy, and safety of prophylactic HPV vaccines in people living with HIV. We registered (...) no differences in the incident and persistent HPV infections in both groups. None of the studies reported data on the incidence of precancerous lesions, or cancer. There were no reports of serious adverse events following vaccination in any of the trials. None of the included studies assessed the effects of HPV vaccines in adolescents living with HIV. Very limited evidence suggests lower immunogenicity of HPV vaccines in HIV positive compared to HIV-negative people. Finally, the long-term effect of the HPV
HIV and drug related stigma and risk-taking behaviors among people who inject drugs: a systematic review and meta-analysis. The impact of HIV-related stigma on people living with HIV has been well documented, but there have been few studies examining how drug-related stigma impacts risk-taking in the lives of people who inject drugs (PWID). This meta-analysis aimed to determine HIV and drug-related stigma and the association it has with risk-taking behaviors among PWID. We searched PubMed (...) the eligibility criteria. Among the potential risk factors: employment status, depression and sharing injecting paraphernalia had a significant relationship with HIV and drug stigma among PWIDs respectively (OR = 0.78, 95%CI = 0.62-0.98), (OR = 1.84, 95%CI = 1.45-2.33) and (OR = 2.20, 95%CI = 1.84-1.63). Illicit drug use related stigma was found to be associated with several concurrent effects. The impact of stigma should be considered in the development of drug use prevention strategies. Perceived stigma
Effectiveness of the female condom in preventing HIV and sexually transmitted infections: a systematic review and meta-analysis. The effectiveness of female condoms for preventing HIV and sexually transmitted infections (STIs) remains inconclusive. We examined the effects of female condoms on the acquisition of HIV and STIs.We searched four databases, two trial registries, and reference lists of relevant publications in October 2018 and updated our search in February 2020. We screened search (...) women. We found that polyurethane female condoms (FC1) plus male condoms may be as effective as male condoms only in reducing HIV acquisition (1 trial, n = 149 women, RR 0.07, 95%CI 0.00-1.38; low-certainty evidence). However, the use of FC1 plus male condoms is superior to male condoms alone in reducing the acquisition of gonorrhoea (2 trials, n = 790, RR 0.59, 95%CI 0.41-0.86; high-certainty evidence) and chlamydia (2 trials, n = 790, RR 0.67, 95%CI 0.47-0.94; high-certainty evidence). Adverse
Long-Acting Cabotegravir and Rilpivirine after Oral Induction for HIV-1 Infection. Long-acting injectable regimens may simplify therapy for patients with humanimmunodeficiencyvirus type 1 (HIV-1) infection.We conducted a phase 3, randomized, open-label trial in which adults with HIV-1 infection who had not previously received antiretroviral therapy were given 20 weeks of daily oral induction therapy with dolutegravir-abacavir-lamivudine. Participants who had an HIV-1 RNA level of less than 50 (...) copies per milliliter after 16 weeks were randomly assigned (1:1) to continue the current oral therapy or switch to oral cabotegravir plus rilpivirine for 1 month followed by monthly injections of long-acting cabotegravir plus rilpivirine. The primary end point was the percentage of participants who had an HIV-1 RNA level of 50 copies per milliliter or higher at week 48 (Food and Drug Administration snapshot algorithm).At week 48, an HIV-1 RNA level of 50 copies per milliliter or higher was found
Long-Acting Cabotegravir and Rilpivirine for Maintenance of HIV-1 Suppression. Simplified regimens for the treatment of humanimmunodeficiencyvirus type 1 (HIV-1) infection may increase patient satisfaction and facilitate adherence.In this phase 3, open-label, multicenter, noninferiority trial involving patients who had had plasma HIV-1 RNA levels of less than 50 copies per milliliter for at least 6 months while taking standard oral antiretroviral therapy, we randomly assigned participants (1 (...) :1) to either continue their oral therapy or switch to monthly intramuscular injections of long-acting cabotegravir, an HIV-1 integrase strand-transfer inhibitor, and long-acting rilpivirine, a nonnucleoside reverse-transcriptase inhibitor. The primary end point was the percentage of participants with an HIV-1 RNA level of 50 copies per milliliter or higher at week 48, determined with the use of the Food and Drug Administration snapshot algorithm.Treatment was initiated in 308 participants per
The Effectiveness of Social Marketing Interventions to Improve HIV Testing Among Gay, Bisexual and Other Men Who Have Sex with Men: A Systematic Review. HIV testing is central to biomedical HIV prevention, but testing among men who have sex with men remains suboptimal. We evaluated effectiveness of mass media and communication interventions to increase HIV testing and explored patterns between study type, internal validity and intervention effectiveness for the first time. Five databases were (...) , one medium and two low) and one RCT (medium validity) reported increased HIV testing. Further work is required to develop and evaluate interventions to increase frequency and maintenance of HIV testing.
Is co-location of services with HIV care associated with improved HIV care outcomes? A systematic review. This systematic review identifies models of service co-location, a structural intervention strategy to remove barriers to HIV care and services, and examines their associations with HIV care outcomes. A cumulative database (e.g., MEDLINE, EMBASE) of HIV, AIDS, and STI literature was systematically searched and manual searches were conducted to identify relevant studies. Thirty-six studies (...) were classified into six models of co-location: HIV care co-located with multiple ancillary services, tuberculosis (TB) care, non-HIV specific primary care, drug abuse treatment, prevention of mother to child transmission programs (PMTCT), and mental health care. More evidence of a positive association was seen for linkage to care and antiretroviral therapy (ART) uptake than for retention and viral suppression. Models of co-location that addressed HIV and non-HIV medical care issues (i.e., co
The Role of Killer Immunoglobulin-Like Receptor Genes in Susceptibility to HIV-1 Infection and Disease Progression: A Meta-Analysis. Genetic studies on the association of the killer immunoglobulin-like receptor (KIR) genes with HIV-1 infection and disease progression have been widely carried out with somewhat contradictory results. Therefore, we undertook a quantitative assessment based on 25 studies [involving 3,216 HIV-1 infected subjects, 1,690 exposed uninfected subjects, 1,262 healthy (...) controls (HCs), 748 typical progressors (TPs), and 244 long-term nonprogressors (LTNPs)] to further define the roles of KIR in HIV-1 control/susceptibility. An overall analysis, showed that, among the 16 KIR genes, the presence of KIR2DS4 may associate with an elevated risk of HIV-1 infection (p < .05, using HCs), whereas KIR3DS1 may associate with a reduced risk (p < .001, using HCs). In the subgroup analyses, among Africans, KIR2DS4 also revealed a significant risk of HIV-1 infection (p < .05
Mycobacterium tuberculosis bloodstream infection prevalence, diagnosis, and mortality risk in seriously ill adults with HIV: a systematic review and meta-analysis of individual patient data. The clinical and epidemiological significance of HIV-associated Mycobacterium tuberculosis bloodstream infection (BSI) is incompletely understood. We hypothesised that M tuberculosis BSI prevalence has been underestimated, that it independently predicts death, and that sputum Xpert MTB/RIF has suboptimal (...) diagnostic yield for M tuberculosis BSI.We did a systematic review and individual patient data (IPD) meta-analysis of studies performing routine mycobacterial blood culture in a prospectively defined patient population of people with HIV aged 13 years or older. Studies were identified through searching PubMed and Scopus up to Nov 10, 2018, without language or date restrictions and through manual review of reference lists. Risk of bias in the included studies was assessed with an adapted QUADAS-2
Cardiac Dysfunction Among PeopleÂ Living With HIV: A Systematic Review and Meta-Analysis. To synthesize existing epidemiological data on cardiac dysfunction in HIV.Data on the burden and risk of humanimmunodeficiencyvirus (HIV) infection-associated cardiac dysfunction have not been adequately synthesized. We performed meta-analyses of extant literature on the frequency of several subtypes of cardiac dysfunction among people living with HIV.We searched electronic databases and reference lists (...) of review articles and combined the study-specific estimates using random-effects model meta-analyses. Heterogeneity was explored using subgroup analyses and meta-regressions.We included 63 reports from 54 studies comprising up to 125,382 adults with HIV infection and 12,655 cases of various cardiac dysfunctions. The pooled prevalence (95% confidence interval) was 12.3% (6.4% to 19.7%; 26 studies) for left ventricular systolic dysfunction (LVSD); 12.0% (7.6% to 17.2%; 17 studies) for dilated
Evolution of Experimental Design and Research Techniques in HIV-1 Reservoir Studies: A Systematic Review. Although HIV-1 has evolved from a deadly to a chronic disease over the past 20 years, an HIV-1 cure is still lacking due to the presence of persisting cellular viral reservoirs which are spread throughout the body in different anatomical compartments. Hence, the identification and characterization of these HIV-1 reservoirs were the focus of many studies during the past decades (...) . In this review, a systematic literature screening and text mining approach were implemented to assess the evolution in experimental design of these HIV-1 reservoir studies. For this purpose, the online databases PubMed, Web of Science, and ClinicalTrials.gov were consulted and 1768 articles were identified, of which 106 are included in this review. We observed several evolutions that indicate a more structured approach of recent HIV-1 reservoir studies. This includes the use of well-characterized patient
Sero-positive HIV result disclosure to sexual partner in Ethiopia: a systematic review and meta-analysis. The infection of HIV continues to be an important public health problem in Ethiopia. Disclosing own HIV positive result is crucial, and considered as a good indicator of behavior change towards HIV/AIDs. A systematic review and meta-analysis was conducted to pool the prevalence of positive HIV status disclosure to sexual partners and determine the influence of selected factors.This (...) systematic review and meta-analysis was conducted in Ethiopia among HIV positive people receiving health care at health facilities. In this review, primary studies were searched in Medline via PubMed, Google scholar and Google up to November, 2018. Data on disclosure of HIV positive result, knowledge of partner's HIV status and prior discussion on HIV were extracted, and effect sizes like proportion and odds ratios were pooled. Heterogeneity and publication bias were assessed by chi-square and I2
Antiretroviral therapy alone versus antiretroviral therapy with a kick and kill approach, on measures of the HIV reservoir in participants with recent HIV infection (the RIVER trial): a phase 2, randomised trial. Antiretroviral therapy (ART) cannot cure HIV infection because of a persistent reservoir of latently infected cells. Approaches that force HIV transcription from these cells, making them susceptible to killing-termed kick and kill regimens-have been explored as a strategy towards (...) an HIV cure. RIVER is the first randomised trial to determine the effect of ART-only versus ART plus kick and kill on markers of the HIV reservoir.This phase 2, open-label, multicentre, randomised, controlled trial was undertaken at six clinical sites in the UK. Patients aged 18-60 years who were confirmed as HIV-positive within a maximum of the past 6 months and started ART within 1 month from confirmed diagnosis were randomly assigned by a computer generated randomisation list to receive ART-only
Antiretroviral therapy and detection of high-grade cervical intraepithelial neoplasia (CIN2+) at post-CIN management follow-up among women living with HIV: a systematic review and meta-analysis. We evaluated the association of antiretroviral therapy (ART), CD4+ count and HIV plasma viral load (PVL) on high-grade cervical intraepithelial neoplasia (CIN2+) detection at follow-up after CIN management among women living with HIV (WLHIV).Medline, Embase, Global Health and PubMed were searched from (...) January 1, 1996 to January 15, 2020. Eligible studies investigated the association of ART, CD4+ count or HIV PVL on histology-confirmed CIN2+ detection at follow-up. Summary estimates were obtained using random-effects meta-analyses; heterogeneity was examined using I2 statistic. PROSPERO registration:CRD42018115631.Eight studies representing 9 populations were identified, including 1,452 WLHIV followed between 6 to 33 months post-CIN management. Pooled data from 8 populations (n=1,408) suggested weak
Prevalence of Different Genotypes of HIV-1 in Injection Drug Users in China: A Systematic Review and Meta-Analysis. Since 1981, an increasing trend in HIV has been observed for transmission via injection drug users (IDUs), sexual transmission and mother-to-child transmission. The IDUs are blamed for early increases in HIV-positive cases in China.HIV genotypes of IDUs were comprehensively analysed to trace the source and relationships of the AIDS epidemic in China.Relevant databases written (...) in English and Chinese were searched. Overall, 7,149 publications were identified in six databases. After screening 7,104 articles according to the inclusion and exclusion criteria, 45 studies consisting of 2,765 cases were finally identified. A meta-analysis was conducted using R MATLAB software, RevMan and SPSS. Subgroup analyses focused on time frame, region, and location of different genotypes of IDUs in China.There were five dominant HIV-1 genotypes among the 2,765 IDU cases. The proportions
/AIDS; stigma and HIV/AIDS; changes in sexual behavior after becoming infected; living with the virus; and pregnancy and motherhood in seropositive women. The moment of diagnosis is of vital importance for these people due to feelings such as disappointment, sadness, fear, despair, lack of awareness, and pain. Social support is highly valued among these people and is linked to an improvement in these peoples' quality of life. Different kinds of stigma accompany people with HIV/AIDS throughout (...) Experiences and Attitudes of People with HIV/AIDS: A Systematic Review of Qualitative Studies. The aim of this article was to explore the experiences and attitudes of people with HIV/AIDS. A systematic review of qualitative studies was carried out. Twenty-seven articles were included, with sample sizes ranging from 3 to 78.

Global and regional estimates of the contribution of herpes simplex virus type 2 infection to HIV incidence: a population attributable fraction analysis using published epidemiological data. A 2017 systematic review and meta-analysis of 55 prospective studies found the adjusted risk of HIV acquisition to be at least tripled in individuals with herpes simplex virus type 2 (HSV-2) infection. We aimed to assess the potential contribution of HSV-2 infection to HIV incidence, given an effect of HSV (...) -2 on HIV acquisition.We used a classic epidemiological formula to estimate the global and regional (WHO regional) population attributable fraction (PAF) and number of incident HIV infections attributable to HSV-2 infection by age (15-24 years, 25-49 years, and 15-49 years), sex, and timing of HSV-2 infection (established vs recently acquired). Estimates were calculated by incorporating HSV-2 and HIV infection data with pooled relative risk (RR) estimates for the effect of HSV-2 infection on HIV
