This study examined regret following HIV serostatus disclosure and associated factors in under-investigated contexts (Mali, Morocco, Democratic Republic of the Congo, Ecuador and Romania). A community-based cross-sectional study was implemented by a mixed consortium [researchers/community-based organizations (CBO)]. Trained CBO members interviewed 1500 PLHIV in contact with CBOs using a 125-item questionnaire. A weighted multivariate logistic regression was performed. Among the 1212 participants included in the analysis, 290 (23.9 %) declared that disclosure was a mistake. Female gender, percentage of PLHIV's network knowing about one's seropositivity from a third party, having suffered rejection after disclosure, having suffered HIV-based discrimination at work, perceived seriousness of infection score, daily loneliness, property index and self-esteem score were independently associated with regret. Discrimination, as well as individual characteristics and skills may affect the disclosure experience. Interventions aiming at improving PLHIV skills and reducing their social isolation may facilitate the disclosure process and avoid negative consequences.

Editor’s notes: Anticipated and perceived consequences of disclosing one’s HIV status are recognized as important drivers for HIV disclosure. This community-based study looked at the experience of disclosing one’s HIV status, and the emotions that were associated with disclosure. The study was nested within a larger cross-sectional research project. 1500 people living with HIV (PLHIV) from Ecuador, the Democratic Republic of the Congo (DRC), Mali, Romania, and Morocco were included in the study. Respondents were asked ‘Was it a mistake to tell others that you are infected with HIV?’ and to answer either ‘yes’ or ‘no.' Participants also responded to questions about the process of disclosure. Among people that had disclosed their status, some 23.9% said that it was a mistake to do so. Almost 40% of participants said that a person in their network learned about their status from a third party. More than 17% of participants responded that they faced rejection and eight percent of participants suffered discrimination at work following disclosure. But this varied greatly across countries. Factors associated with feeling regret after disclosing one’s status included being a female, perceived seriousness of HIV infection, and feeling lonely every day. This study highlights the fact that status disclosure can be emotional and stressful for people living with HIV. This suggests that people living with HIV must weigh the costs and benefits of disclosure before doing so and programmes that empower them to make informed decisions about disclosure may be beneficial.

Counting and classifying global deaths

Global, regional, and national incidence and mortality for HIV, tuberculosis, and malaria during 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

Murray CJ, Ortblad KF, Guinovart C, et al. Lancet. 2014 Sep 13;384(9947):1005-70. doi: 10.1016/S0140-6736(14)60844-8. Epub 2014 Jul 22.

Background: The Millennium Declaration in 2000 brought special global attention to HIV, tuberculosis, and malaria through the formulation of Millennium Development Goal (MDG) 6. The Global Burden of Disease 2013 study provides a consistent and comprehensive approach to disease estimation for between 1990 and 2013, and an opportunity to assess whether accelerated progress has occurred since the Millennium Declaration.

Methods: To estimate incidence and mortality for HIV, we used the UNAIDS Spectrum model appropriately modified based on a systematic review of available studies of mortality with and without antiretroviral therapy (ART). For concentrated epidemics, we calibrated Spectrum models to fit vital registration data corrected for misclassification of HIV deaths. In generalised epidemics, we minimised a loss function to select epidemic curves most consistent with prevalence data and demographic data for all-cause mortality. We analysed counterfactual scenarios for HIV to assess years of life saved through prevention of mother-to-child transmission (PMTCT) and ART. For tuberculosis, we analysed vital registration and verbal autopsy data to estimate mortality using cause of death ensemble modelling. We analysed data for corrected case-notifications, expert opinions on the case-detection rate, prevalence surveys, and estimated cause-specific mortality using Bayesian meta-regression to generate consistent trends in all parameters. We analysed malaria mortality and incidence using an updated cause of death database, a systematic analysis of verbal autopsy validation studies for malaria, and recent studies (2010-13) of incidence, drug resistance, and coverage of insecticide-treated bednets.

Findings: Globally in 2013, there were 1.8 million new HIV infections (95% uncertainty interval 1.7 million to 2.1 million), 29.2 million prevalent HIV cases (28.1 to 31.7), and 1.3 million HIV deaths (1.3 to 1.5). At the peak of the epidemic in 2005, HIV caused 1.7 million deaths (1.6 million to 1.9 million). Concentrated epidemics in Latin America and eastern Europe are substantially smaller than previously estimated. Through interventions including PMTCT and ART, 19.1 million life-years (16.6 million to 21.5 million) have been saved, 70.3% (65.4 to 76.1) in developing countries. From 2000 to 2011, the ratio of development assistance for health for HIV to years of life saved through intervention was US$ 4498 in developing countries. Including in HIV-positive individuals, all-form tuberculosis incidence was 7.5 million (7.4 million to 7.7 million), prevalence was 11.9 million (11.6 million to 12.2 million), and number of deaths was 1.4 million (1.3 million to 1.5 million) in 2013. In the same year and in only individuals who were HIV-negative, all-form tuberculosis incidence was 7.1 million (6.9 million to 7.3 million), prevalence was 11.2 million (10.8 million to 11.6 million), and number of deaths was 1.3 million (1.2 million to 1.4 million). Annualised rates of change (ARC) for incidence, prevalence, and death became negative after 2000. Tuberculosis in HIV-negative individuals disproportionately occurs in men and boys (versus women and girls); 64.0% of cases (63.6 to 64.3) and 64.7% of deaths (60.8 to 70.3). Globally, malaria cases and deaths grew rapidly from 1990 reaching a peak of 232 million cases (143 million to 387 million) in 2003 and 1.2 million deaths (1.1 million to 1.4 million) in 2004. Since 2004, child deaths from malaria in sub-Saharan Africa have decreased by 31.5% (15.7 to 44.1). Outside of Africa, malaria mortality has been steadily decreasing since 1990.

Interpretation: Our estimates of the number of people living with HIV are 18.7% smaller than UNAIDS's estimates in 2012. The number of people living with malaria is larger than estimated by WHO. The number of people living with HIV, tuberculosis, or malaria have all decreased since 2000. At the global level, upward trends for malaria and HIV deaths have been reversed and declines in tuberculosis deaths have accelerated. 101 countries (74 of which are developing) still have increasing HIV incidence. Substantial progress since the Millennium Declaration is an encouraging sign of the effect of global action.

Abstract  Full-text [free] access

Editor’s notes: The Global Burden of Disease (GBD) study uses standard methods to compare and track over time national distributions of deaths by cause, and the prevalence of disease and disability.  This detailed report focuses on HIV, TB and Malaria. It presents regional summaries of incidence, prevalence and mortality rates, and national estimates of the number of male and female deaths and new infections. Point estimates are shown for 2013, and annualised rates of change for 1990-2000 and 2000-2013. These highlight the contrasting trends in disease impact before and after the formulation of the Millennium Development Goal to combat these diseases.  The global peak of HIV mortality occurred in 2005, but regional annualised rates of change for 2000-2013 indicate that HIV deaths are still increasing significantly in east Asia, southern Africa, and most rapidly in eastern Europe.

The GBD 2013 global estimates of new infections and deaths agree closely with the corresponding estimates made by UNAIDS. But there are significant differences in the respective estimates of the number of people currently living with HIV (UNAIDS estimates are some 18% higher), and historical trends in AIDS deaths, with UNAIDS judging that the recent fall has been steeper. These differences are attributed primarily to methods used in the GBD study to ensure that the sum of deaths from specific causes fits the estimated all cause total, and to varying assumptions about historical survival patterns following HIV infection. 

It may be worthwhile to look at a comment by Michel Sidibé, Mark Dybul, and Deborah Birx in the Lancet on MDG 6 and beyond: from halting and reversing AIDS to ending the epidemic which refers to this study.

Falling death rates among people in HIV care: AIDS remains common, non-AIDS cancers need attention

Trends in underlying causes of death in people with HIV from 1999 to 2011 (D:A:D): a multicohort collaboration.

Smith CJ, Ryom L, Weber R, Morlat P, Pradier C, Reiss P, Kowalska JD, de Wit S, Law M, el Sadr W, Kirk O, Friis-Moller N, Monforte A, Phillips AN, Sabin CA, Lundgren JD, D:A:D Study Group. Lancet. 2014 Jul 19;384(9939):241-8. doi: 10.1016/S0140-6736(14)60604-8.

Background: With the advent of effective antiretroviral treatment, the life expectancy for people with HIV is now approaching that seen in the general population. Consequently, the relative importance of other traditionally non-AIDS-related morbidities has increased. We investigated trends over time in all-cause mortality and for specific causes of death in people with HIV from 1999 to 2011.

Methods: Individuals from the Data collection on Adverse events of anti-HIV Drugs (D:A:D) study were followed up from March, 1999, until death, loss to follow-up, or Feb 1, 2011, whichever occurred first. The D:A:D study is a collaboration of 11 cohort studies following HIV-1-positive individuals receiving care at 212 clinics in Europe, USA, and Australia. All fatal events were centrally validated at the D:A:D coordinating centre using coding causes of death in HIV (CoDe) methodology. We calculated relative rates using Poisson regression.

Findings: 3 909 of the 49 731 D:A:D study participants died during the 308 719 person-years of follow-up (crude incidence mortality rate, 12.7 per 1 000 person-years [95% CI 12.3-13.1]). Leading underlying causes were: AIDS-related (1 123 [29%] deaths), non-AIDS-defining cancers (590 [15%] deaths), liver disease (515 [13%] deaths), and cardiovascular disease (436 [11%] deaths). Rates of all-cause death per 1 000 person-years decreased from 17.5 in 1999-2000 to 9.1 in 2009-11; we saw similar decreases in death rates per 1 000 person-years over the same period for AIDS-related deaths (5.9 to 2.0), deaths from liver disease (2.7 to 0.9), and cardiovascular disease deaths (1.8 to 0.9). However, non-AIDS cancers increased slightly from 1.6 per 1 000 person-years in 1999-2000 to 2.1 in 2009-11 (p=0.58). After adjustment for factors that changed over time, including CD4 cell count, we detected no decreases in AIDS-related death rates (relative rate for 2009-11 vs 1999-2000: 0.92 [0.70-1.22]). However, all-cause (0.72 [0.61-0.83]), liver disease (0.48 [0.32-0.74]), and cardiovascular disease (0.33 [0.20-0.53) death rates still decreased over time. The percentage of all deaths that were AIDS-related (87/256 [34%] in 1999-2000 and 141/627 [22%] in 2009-11) and liver-related (40/256 [16%] in 1999-2000 and 64/627 [10%] in 2009-11) decreased over time, whereas non-AIDS cancers increased (24/256 [9%] in 1999-2000 to 142/627 [23%] in 2009-11).

Interpretation: Recent reductions in rates of AIDS-related deaths are linked with continued improvement in CD4 cell count. We hypothesise that the substantially reduced rates of liver disease and cardiovascular disease deaths over time could be explained by improved use of non-HIV-specific preventive interventions. Non-AIDS cancer is now the leading non-AIDS cause and without any evidence of improvement.

Abstract access

Editor’s notes: Causes of death among people with HIV help to identify priorities for HIV care services. This very large cohort study, including nearly 50 000 HIV-positive people in industrialised country clinics, reports on changes in causes of death since 1999. Effective antiretroviral treatment was widely available for this cohort. All-cause mortality decreased over time, partly explained by effective antiretroviral therapy and increased CD4 cell counts. Death rates due to AIDS declined over time. However, even in 2009-11, AIDS remained a leading cause of death, suggesting that further efforts to diagnose and treat people with HIV earlier are required.

Deaths due to cardiovascular and liver-related causes decreased over time, even after adjustment for other potentially contributing factors. This suggests that people in this cohort were benefitting not only from good management of their HIV disease, but also from other preventive programmes for cardiovascular and other risk factors. By contrast, death rates due to non-AIDS-related cancers have not fallen, suggesting that more attention to prevention and early detection of common malignancies is needed.

Dolutegravir-based regimen superior to efavirenz-based regimen in treatment-naive patients

Dolutegravir plus abacavir-lamivudine for the treatment of HIV-1 infection.

Walmsley SL, Antela A, Clumeck N, Duiculescu D, Eberhard A, Gutiérrez F, Hocqueloux L, Maggiolo F, Sandkovsky U, Granier C, Pappa K, Wynne B, Min S, Nichols G; SINGLE Investigators.  N Engl J Med. 2013 Nov 7;369(19):1807-18. doi: 10.1056/NEJMoa1215541.

Background: Dolutegravir (S/GSK1349572), a once-daily, unboosted integrase inhibitor, was recently approved in the United States for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in combination with other antiretroviral agents. Dolutegravir, in combination with abacavir-lamivudine, may provide a simplified regimen.

Methods: We conducted a randomized, double-blind, phase 3 study involving adult participants who had not received previous therapy for HIV-1 infection and who had an HIV-1 RNA level of 1 000 copies per milliliter or more. Participants were randomly assigned to dolutegravir at a dose of 50 mg plus abacavir-lamivudine once daily (DTG-ABC-3TC group) or combination therapy with efavirenz-tenofovir disoproxil fumarate (DF)-emtricitabine once daily (EFV-TDF-FTC group). The primary end point was the proportion of participants with an HIV-1 RNA level of less than 50 copies per milliliter at week 48. Secondary end points included the time to viral suppression, the change from baseline in CD4+ T-cell count, safety, and viral resistance.

Results: A total of 833 participants received at least one dose of study drug. At week 48, the proportion of participants with an HIV-1 RNA level of less than 50 copies per milliliter was significantly higher in the DTG-ABC-3TC group than in the EFV-TDF-FTC group (88% vs. 81%, P=0.003), thus meeting the criterion for superiority. The DTG-ABC-3TC group had a shorter median time to viral suppression than did the EFV-TDF-FTC group (28 vs. 84 days, P<0.001), as well as greater increases in CD4+ T-cell count (267 vs. 208 per cubic millimeter, P<0.001). The proportion of participants who discontinued therapy owing to adverse events was lower in the DTG-ABC-3TC group than in the EFV-TDF-FTC group (2% vs. 10%); rash and neuropsychiatric events (including abnormal dreams, anxiety, dizziness, and somnolence) were significantly more common in the EFV-TDF-FTC group, whereas insomnia was reported more frequently in the DTG-ABC-3TC group. No participants in the DTG-ABC-3TC group had detectable antiviral resistance; one tenofovir DF-associated mutation and four efavirenz-associated mutations were detected in participants with virologic failure in the EFV-TDF-FTC group.

Conclusions: Dolutegravir plus abacavir-lamivudine had a better safety profile and was more effective through 48 weeks than the regimen with efavirenz-tenofovir DF-emtricitabine.

Abstract access 

Editor’s notes: In this 48- week double-blind randomized controlled trial in treatment-naive patients, dolutegravir plus abacavir / lamivudine outperformed efavirenz plus tenofovir / emtricitabine in terms of efficacy (viral suppression at 48 weeks and time to viral suppression), immunological recovery and discontinuation of therapy for adverse events. The difference in virologic response was largely due to higher levels of regimen discontinuation for adverse events in the efavirenz arm. The superior virologic response in the dolutegravir arm was consistent regardless of baseline viral load (above or below 100 000 copies/ml). 4% of patients in both arms developed virologic failure (two consecutive viral load measures >50 copies/ml). As expected, non-nucleoside reverse transcriptase inhibitors (NNRTI) mutations and K65R mutations emerged in patients failing the efavirenz-based regimen; however no mutations emerged amongst patients failing the dolutegravir-based regimen.

 Dolutegravir is clearly an attractive future treatment option: its long half-life supports once a day dosing; there are few relevant drug interactions; trials performed to date show that it is well tolerated; and a fixed drug combination tablet of dolutegravir, abacavir and lamivudine is currently being developed. However, until the cost is lowered we are unlikely to see widespread use of this drug.
