BackgroundWe set out to estimate historical trends in HIV incidence in Australian men who have sex with men with respect to age at infection and birth cohort.MethodsA modified back‐projection technique is applied to data from the HIV/AIDS Surveillance System in Australia, including "newly diagnosed HIV infections", "newly acquired HIV infections" and "AIDS diagnoses", to estimate trends in HIV incidence over both calendar time and age at infection.ResultsOur results demonstrate that since 2000, there has been an increase in new HIV infections in Australian men who have sex with men across all age groups. The estimated mean age at infection increased from ~35 years in 2000 to ~37 years in 2007. When the epidemic peaked in the mid 1980s, the majority of the infections (56%) occurred among men aged 30 years and younger; 30% occurred in ages 31 to 40 years; and only ~14% of them were attributed to the group who were older than 40 years of age. In 2007, the proportion of infections occurring in persons 40 years or older doubled to 31% compared to the mid 1980s, while the proportion of infections attributed to the group younger than 30 years of age decreased to 36%.ConclusionThe distribution of HIV incidence for birth cohorts by infection year suggests that the HIV epidemic continues to affect older homosexual men as much as, if not more than, younger men. The results are useful for evaluating the impact of the epidemic across successive birth cohorts and study trends among the age groups most at risk.

IntroductionA recent meta‐analysis of 4 RCTs showed an increased rate of suicidality events (suicidal ideation or attempted/completed suicide) associated with efavirenz (EFV) compared to other regimens, but only a trend towards a higher rate of completed/attempted suicides, as only 17 events occurred. We investigated the association between EFV use and completed suicide.Materials and MethodsAll D:A:D participants were followed from study entry to the first of death, last study visit or 1 February 2013. Deaths are centrally validated using cause of death methodology, which assigns underlying, immediate and up to four contributing causes of death. Two endpoints were considered: 1) suicide or psychiatric disease as the underlying cause, and 2) suicide or psychiatric disease mentioned as an underlying, immediate or contributing cause of death (anywhere). Adjusted rate ratios were calculated using Poisson regression.ResultsA total of 4420 deaths occurred in 49,717 people over 371,333 person‐years (PY) (rate 11.9 per 1000 PY; 95% CI 11.6–12.3). A total of 193 deaths (rate 0.52; 0.45–0.59) had an underlying cause of suicide or psychiatric disease, and 482 deaths (1.30; 1.18–1.41) had suicide or psychiatric disease mentioned anywhere. A strong association with current CD4 count was seen: for suicide or psychiatric disease mentioned anywhere, rates were: 3.18 (2.55–3.80) for <200 cells/uL, 1.60 (1.29–1.90) for 201–350 cells/uL, 1.07 (0.86–1.29) for 351–500 cells/uL, 0.95 (0.80–1.09) for >500 cells/uL and 1.30 (1.18–1.41) for unknown. Highest rate of suicide or psychiatric deaths were seen in ART‐experienced people currently off ART, but no differences were seen according to current ART regimen, which remained after adjustment (Table 1). Consistent results were obtained when considering additional endpoints of suicide alone as the underlying cause and death from suicide or any possibly related cause (psychiatric disease, drug overdose, alcohol related, accidental or violent), as well as considering recent EFV use in the previous 3 and 6 months.ConclusionsThe finding of no higher death rates from suicide amongst those receiving EFV is reassuring. However, there is likely confounding by indication in our observational study. In light of conflicting results from RCTs, this potentially could suggest that in clinical practice EFV may be less frequently prescribed in those with underlying psychiatric conditions.

IntroductionHIV‐positive (HIV+) temporary residents living in Australia legally are unable to access government subsidized antiretroviral treatment (ART) which is provided via Medicare to Australian citizens and permanent residents. Currently, there is no information systematically being collected on non‐Medicare eligible HIV+ patients in Australia. The objectives of this study are to describe the population recruited to the Australian HIV Observational Database (AHOD) Temporary Residents Access Study (ATRAS) and to determine the short‐ and long‐term outcomes of receiving (subsidized) optimal ART and the impact on onwards HIV transmission.MethodsATRAS was established in 2011. Eligible patients were recruited via the AHOD network. Key HIV‐related characteristics were recorded at baseline and prospectively. Additional visa‐related information was also recorded at baseline, and updated annually. Descriptive statistics were used to describe the ATRAS cohort in terms of visa status by key demographic characteristics, including sex, region of birth, and HIV disease status. CD4 cell count (mean and SD) and the proportion with undetectable (<50 copies/ml) HIV viral load are reported at baseline, 6 and 12 months of follow‐up. We also estimate the proportion reduction of onward HIV transmission based on the reduction in proportion of people with detectable HIV viral load.ResultsA total of 180 patients were recruited to ATRAS by June 2012, and by July 2013 39 patients no longer required ART via ATRAS, 35 of whom became eligible for Medicare‐funded medication. At enrolment, 63% of ATRAS patients were receiving ART from alternative sources, 47% had an undetectable HIV viral load (<50 copies/ml) and the median CD4 cell count was 343 cells/µl (IQR: 222–479). At 12 months of follow‐up, 85% had an undetectable viral load. We estimated a 75% reduction in the risk of onward HIV transmission with the improved rate of undetectable viral load.ConclusionsThe immunological and virological improvements highlight the importance of supplying optimal ART to this vulnerable population. The increase in proportion with undetectable HIV viral load shows the potentially significant impact on HIV transmission in addition to the personal health benefit for each individual.

IntroductionHIV prevention strategies are moving towards reducing plasma HIV RNA viral load in all HIV‐positive persons, including those undiagnosed, treatment naïve, on or off antiretroviral therapy. A proxy population for those undiagnosed are patients that present late to care with advanced HIV. The objectives of this analysis are to examine factors associated with patients presenting with advanced HIV, and establish rates of treatment interruption and modification after initiating ART.MethodsWe deterministically linked records from the Australian HIV Observational Database to the Australian National HIV Registry to obtain information related to HIV diagnosis. Logistic regression was used to identify factors associated with advanced HIV diagnosis. We used survival methods to evaluate rates of ART initiation by diagnosis CD4 count strata and by calendar year of HIV diagnosis. Cox models were used to determine hazard of first ART treatment interruption (duration >30 days) and time to first major ART modification.ResultsFactors associated (p<0.05) with increased odds of advanced HIV diagnosis were sex, older age, heterosexual mode of HIV exposure, born overseas and rural–regional care setting. Earlier initiation of ART occurred at higher rates in later periods (2007–2012) in all diagnosis CD4 count groups. We found an 83% (69, 91%) reduction in the hazard of first treatment interruption comparing 2007–2012 versus 1996–2001 (p<0.001), and no difference in ART modification for patients diagnosed with advanced HIV.ConclusionsRecent HIV diagnoses are initiating therapy earlier in all diagnosis CD4 cell count groups, potentially lowering community viral load compared to earlier time periods. We found a marked reduction in the hazard of first treatment interruption, and found no difference in rates of major modification to ART by HIV presentation status in recent periods.

BackgroundRecent papers have suggested that expanded combination antiretroviral treatment (cART) through lower viral load may be a strategy to reduce HIV transmission at a population level. We assessed calendar trends in detectable viral load in patients recruited to the Australian HIV Observational Database who were receiving cART.MethodsPatients were included in analyses if they had started cART (defined as three or more antiretrovirals) and had at least one viral load assessment after 1 January 1997. We analyzed detectable viral load (>400 copies/ml) in the first and second six months of each calendar year while receiving cART. Repeated measures logistic regression methods were used to account for within and between patient variability. Rates of detectable viral load were predicted allowing for patients lost to follow up.ResultsAnalyses were based on 2439 patients and 31,339 viral load assessments between 1 January 1997 and 31 March 2009. Observed detectable viral load in patients receiving cART declined to 5.3% in the first half of 2009. Predicted detectable viral load based on multivariate models, allowing for patient loss to follow up, also declined over time, but at higher levels, to 13.8% in 2009.ConclusionsPredicted detectable viral load in Australian HIV Observational Database patients receiving cART declined over calendar time, albeit at higher levels than observed. However, over this period, HIV diagnoses and estimated HIV incidence increased in Australia.
BACKGROUND Financial incentives and audit plus feedback on performance are two strategies commonly used by governments to motivate general practitioners (GP) to undertake specific healthcare activities. However, in recent years, governments have reduced or removed incentive payments without evidence of the potential impact on GP behaviour and patient outcomes. This trial (known as ACCEPt-able) aims to determine whether preventive care activities in general practice are sustained when financial incentives and/or external audit plus feedback on preventive care activities are removed. The activity investigated is annual chlamydia testing for 16- to 29-year-old adults, a key preventive health strategy within this age group. METHODS/DESIGN ACCEPt-able builds on a large cluster randomised controlled trial (RCT) that evaluated a 3-year chlamydia testing intervention in general practice. GPs were provided with a support package to facilitate annual chlamydia testing of all sexually active 16- to 29-year-old patients. This package included financial incentive payments to the GP for each chlamydia test conducted and external audit plus feedback on each GP's chlamydia testing rates. ACCEPt-able is a factorial cluster RCT in which general practices are randomised to one of four groups: (i) removal of audit plus feedback-continue to receive financial incentive payments for each chlamydia test; (ii) removal of financial incentive payments-continue to receive audit plus feedback; (iii) removal of financial incentive payments and audit plus feedback; and (iv) continue financial incentive payments and audit plus feedback. The primary outcome is chlamydia testing rate measured as the proportion of sexually active 16- to 29-year-olds who have a GP consultation within a 12-month period and at least one chlamydia test. DISCUSSION This will be the first RCT to examine the impact of removal of financial incentive payments and audit plus feedback on the chlamydia testing behaviour of GPs. This trial is particularly timely and will increase our understanding about the impact of financial incentives and audit plus feedback on GP behaviour when governments are looking for opportunities to control healthcare budgets and maximise clinical outcomes for money spent. The results of this trial will have implications for supporting preventive health measures beyond the content area of chlamydia. TRIAL REGISTRATION The trial has been registered on the Australian and New Zealand Clinical Trials Registry ( ACTRN12614000595617 ).

AbstractIntroductionPeople living with HIV (PLHIV) have an elevated risk of atherosclerotic cardiovascular disease (CVD) compared to their HIV‐negative peers. Expanding statin use may help alleviate this burden. However, the choice of statin in the context of antiretroviral therapy is challenging. Pravastatin and pitavastatin improve cholesterol levels in PLHIV without interacting substantially with antiretroviral therapy. They are also more expensive than most statins. We evaluated the cost‐effectiveness of pravastatin and pitavastatin for the primary prevention of CVD among PLHIV in Thailand who are not currently using lipid‐lowering therapy.MethodsWe developed a discrete‐state microsimulation model that randomly selected (with replacement) individuals from the TREAT Asia HIV Observational Database cohort who were aged 40 to 75 years, receiving antiretroviral therapy in Thailand, and not using lipid‐lowering therapy. The model simulated each individual's probability of experiencing CVD. We evaluated: (1) treating no one with statins; (2) treating everyone with pravastatin 20mg/day (drug cost 7568 Thai Baht ($US243)/year) and (3) treating everyone with pitavastatin 2 mg/day (drug cost 8182 Baht ($US263)/year). Direct medical costs and quality‐adjusted life‐years (QALYs) were assigned in annual cycles over a 20‐year time horizon and discounted at 3% per year. We assumed the Thai healthcare sector perspective.ResultsPravastatin was estimated to be less effective and less cost‐effective than pitavastatin and was therefore dominated (extended) by pitavastatin. Patients receiving pitavastatin accumulated 0.042 additional QALYs compared with those not using a statin, at an extra cost of 96,442 Baht ($US3095), giving an incremental cost‐effectiveness ratio of 2,300,000 Baht ($US73,812)/QALY gained. These findings were sensitive to statin costs and statin efficacy, pill burden, and targeting of PLHIV based on CVD risk. At a willingness‐to‐pay threshold of 160,000 Baht ($US5135)/QALY gained, we estimated that pravastatin would become cost‐effective at an annual cost of 415 Baht ($US13.30)/year and pitavastatin would become cost‐effective at an annual cost of 600 Baht ($US19.30)/year.ConclusionsNeither pravastatin nor pitavastatin were projected to be cost‐effective for the primary prevention of CVD among PLHIV in Thailand who are not currently using lipid‐lowering therapy. We do not recommend expanding current use of these drugs among PLHIV in Thailand without substantial price reduction.

IntroductionThere is a lack of data on potential gender differences in the use of interventions to prevent and treat cardiovascular disease (CVD) in HIV‐positive individuals. We investigated whether such differences exist in the D:A:D study.Materials and MethodsFollow‐up was from 01/02/99 until the earliest of death, 6 months after last visit or 01/02/13. Rates of initiation of lipid‐lowering drugs (LLDs), angiotensin‐converting enzyme inhibitors (ACEIs), anti‐hypertensives and receipt of invasive cardiovascular procedures (ICPs; bypass, angioplasty, endarterectomy) were calculated in those without a myocardial infarction (MI) or stroke at baseline, overall and in groups known to be at higher CVD risk: (i) age >50, (ii) total cholesterol >6.2 mmol/l, (iii) triglyceride >2.3 mmol/l, (iv) hypertension, (v) previous MI, (vi) diabetes, or (vii) predicted 10‐year CVD risk >10%. Poisson regression was used to assess whether rates of initiation were higher in men than women, after adjustment for these factors.ResultsAt enrolment, women (n=13,039; median (interquartile range) 34 (29–40) years) were younger than men (n=36,664, 39 (33–46) years, p=0.001), and were less likely to be current smokers (29% vs. 39%, p=0.0001), to have diabetes (2% vs. 3%, p=0.0001) or to have hypertension (7% vs. 11%, p=0.0001). Of 49,071 individuals without a MI/stroke at enrolment, 0.6% women vs. 2.1% men experienced a MI while 0.8% vs. 1.3% experienced a stroke. Overall, women received ICPs at a rate of 0.07/100 person‐years (PYRS) compared to 0.29/100 PYRS in men. Similarly, the rates of initiation of LLDs (1.28 vs. 2.46), anti‐hypertensives (1.11 vs. 1.38) and ACEIs (0.82 vs. 1.37) were all significantly lower in women than men (Table 1). As expected, initiation rates of each intervention were higher in the groups determined to be at moderate/high CVD risk; however, within each high‐risk group, initiation rates of most interventions (with the exception of anti‐hypertensives) were generally lower in women than men. These gender differences persisted after adjustment for potential confounders (Table 1).ConclusionUse of most CVD interventions was lower among women than men in the D:A:D study. Our findings suggest that actions should be taken to ensure that both men and women are monitored for CVD and, if eligible, receive appropriate CVD interventions.
Background: Having 90% of patients on antiretroviral therapy (ART) and achieving an undetectable viral load (VL) is 1 of the 90: 90: 90 by 2020 targets. In this global analysis, we investigated the proportions of adult and paediatric patients with VL suppression in the first 3 years after ART initiation. Methods: Patients from the IeDEA cohorts who initiated ART between 2010 and 2014 were included. Proportions with VL suppression (<1000 copies/ mL) were estimated using (1) strict intention to treat (ITT)-loss to follow-up (LTFU) and dead patients counted as having detectable VL; and (2) modified ITT-LTFU and dead patients were excluded. Logistic regression was used to identify predictors of viral suppression at 1 year after ART initiation using modified ITT. Results: A total of 35,561 adults from 38 sites/16 countries and 2601 children from 18 sites/6 countries were included. When comparing strict with modified ITT methods, the proportion achieving VL suppression at 3 years from ART initiation changed from 45.1% to 90.2% in adults, and 60.6% to 80.4% in children. In adults, older age, higher CD4 count preART, and homosexual/bisexual HIV exposure were associated with VL suppression. In children, older age and higher CD4 percentage pre-ART showed significant associations with VL suppression. Conclusions: Large increases in the proportion of VL suppression in adults were observed when we excluded those who were LTFU or had died. The increases were less pronounced in children. Greater emphasis should be made to minimize LTFU and maximize patient retention in HIV-infected patients of all age groups. ; U.S. National Institutes of Health's National Institute of Allergy and Infectious Diseases ; Eunice Kennedy Shriver National Institute of Child Health and Human Development ; National Cancer Institute ; Centers for Disease Control and Prevention, USA ; Agency for Healthcare Research and Quality, USA ; Health Resources and Services Administration, USA ; Canadian Institutes of Health Research, Canada ; Ontario Ministry of Health and Long Term Care ; Government of Alberta, Canada ; Intramural Research Program of the National Cancer Institute ; Australian Government Department of Health and Ageing ; UNSW, Kirby Inst, Sydney, NSW 2052, Australia ; Johns Hopkins Bloomberg Sch Publ Hlth, Dept Epidemiol, Baltimore, MD USA ; Fdn Huesped, Buenos Aires, DF, Argentina ; Univ Chile, Sch Med, Santiago, Chile ; Fdn Arriaran, Santiago, Chile ; Univ Cape Town, Sch Publ Hlth & Family Med, Cape Town, South Africa ; Childrens Hosp 2, Ho Chi Minh City, Vietnam ; Univ Cape Town, Dept Paediat & Child Hlth, Cape Town, South Africa ; Univ Calgary, Calgary, AB, Canada ; YRGCARE Med Ctr, Madras, Tamil Nadu, India ; Univ Fed Sao Paulo, Pediat Infect Dis Div, Escola Paulista Med, Sao Paulo, Brazil ; Johns Hopkins Univ, Dept Med, Div Infect Dis, Baltimore, MD USA ; Univ Stellenbosch, Dept Med, Div Infect Dis, Cape Town, South Africa ; Tygerberg Hosp, Cape Town, South Africa ; Univ Bern, Inst Social & Prevent Med, Bern, Switzerland ; Univ Fed Sao Paulo, Pediat Infect Dis Div, Escola Paulista Med, Sao Paulo, Brazil ; NCI: U01AI035004 ; NCI: U01AI035039 ; NCI: U01AI035040 ; NCI: U01AI035041 ; NCI: U01AI035042 ; NCI: U01AI037613 ; NCI: U01AI037984 ; NCI: U01AI038855 ; NCI: U01AI038858 ; NCI: U01AI042590 ; NCI: U01AI068634 ; NCI: U01AI068636 ; NCI: U01AI069432 ; NCI: U01AI069434 ; Centers for Disease Control and Prevention, USA: CDC-200-2006-18797 ; Centers for Disease Control and Prevention, USA: CDC-200-2015-63931 ; Agency for Healthcare Research and Quality, USA: 90047713 ; Health Resources and Services Administration, USA: 90051652 ; Canadian Institutes of Health Research, Canada: CBR-86906 ; Canadian Institutes of Health Research, Canada: CBR-94036 ; Canadian Institutes of Health Research, Canada: HCP-97105 ; Canadian Institutes of Health Research, Canada: TGF-96118 ; NCI: P30AI027757 ; NCI: P30AI027763 ; NCI: P30AI027767 ; NCI: P30AI036219 ; NCI: P30AI050410 ; NCI: P30AI094189 ; NCI: P30AI110527 ; NCI: P30MH62246 ; NCI: R01AA016893 ; NCI: R01CA165937 ; NCI: R01DA004334 ; NCI: R01DA011602 ; NCI: R01DA012568 ; NCI: R24AI067039 ; NCI: U01AA013566 ; NCI: U01AA020790 ; NCI: U01AI1031834 ; NCI: U01AI034989 ; NCI: U01AI034993 ; NCI: U01AI034994 ; NCI: M01RR000052 ; NCI: U54MD007587 ; NCI: UL1RR024131 ; NCI: UL1TR000004 ; NCI: UL1TR000083 ; NCI: UL1TR000454 ; NCI: UM1AI035043 ; NCI: Z01CP010214 ; NCI: Z01CP010176 ; NCI: U01AI069907 ; NCI: U01AI069923 ; NCI: U01AI069924 ; NCI: U01AI069918 ; NCI: F31DA037788 ; NCI: G12MD007583 ; NCI: K01A1093197 ; NCI: K23EY013707 ; NCI: K24DA000432 ; NCI: K24AI065298 ; NCI: KL2TR000421 ; NCI: N02CP055504 ; NCI: U01AI103390 ; NCI: U01AI103397 ; NCI: U01AI103401 ; NCI: U01AI103408 ; NCI: U01DA036935 ; NCI: U01HD032632 ; NCI: U10EY008057 ; NCI: U10EY008052 ; NCI: U10EY008067 ; NCI: U24AA020794 ; Web of Science

IntroductionHIV‐positive patients receiving combination antiretroviral therapy (cART) frequently experience metabolic complications such as dyslipidemia and insulin resistance, as well as lipodystrophy, increasing the risk of cardiovascular disease (CVD) and diabetes mellitus (DM). Rates of DM and other glucose‐associated disorders among HIV‐positive patients have been reported to range between 2 and 14%, and in an ageing HIV‐positive population, the prevalence of DM is expected to continue to increase. This study aims to develop a model to predict the short‐term (six‐month) risk of DM in HIV‐positive populations and to compare the existing models developed in the general population.MethodsAll patients recruited to the Data Collection on Adverse events of Anti‐HIV Drugs (D:A:D) study with follow‐up data, without prior DM, myocardial infarction or other CVD events and with a complete DM risk factor profile were included. Conventional risk factors identified in the general population as well as key HIV‐related factors were assessed using Poisson‐regression methods. Expected probabilities of DM events were also determined based on the Framingham Offspring Study DM equation. The D:A:D and Framingham equations were then assessed using an internal‐external validation process; area under the receiver operating characteristic (AUROC) curve and predicted DM events were determined.ResultsOf 33,308 patients, 16,632 (50%) patients were included, with 376 cases of new onset DM during 89,469 person‐years (PY). Factors predictive of DM included higher glucose, body mass index (BMI) and triglyceride levels, and older age. Among HIV‐related factors, recent CD4 counts of<200 cells/µL and lipodystrophy were predictive of new onset DM. The mean performance of the D:A:D and Framingham equations yielded AUROC of 0.894 (95% CI: 0.849, 0.940) and 0.877 (95% CI: 0.823, 0.932), respectively. The Framingham equation over‐predicted DM events compared to D:A:D for lower glucose and lower triglycerides, and for BMI levels below 25 kg/m2.ConclusionsThe D:A:D equation performed well in predicting the short‐term onset of DM in the validation dataset and for specific subgroups provided better estimates of DM risk than the Framingham.

AbstractIntroductionIn 2015, the World Health Organization recommended that all HIV‐infected individuals consider ART initiation as soon as possible after diagnosis. Sex differences in choice of initial ART regimen, indications for switching, time to switching and choice of second‐line regimens have not been well described. The aims of this study were to describe first‐line ART and CD4 count at ART initiation by sex, calendar year and region, and to analyse time to change or interruption in first‐line ART, according to sex in each region.MethodsParticipating cohorts included: Southern, East and West Africa (IeDEA‐Africa), North America (NA‐ACCORD), Caribbean, Central/South America (CCASAnet) and Asia‐Pacific including Australia (IeDEA Asia‐Pacific). The primary outcomes analysed for each region and according to sex were choice of initial ART, time to switching and time to discontinuation of the first‐line regimen.Results and DiscussionThe combined cohort data set comprised of 715,252 participants across seven regions from low‐ to high‐income settings. The median CD4 count at treatment initiation was lower in men compared with women in nearly all regions and time periods. Women from North America and Southern Africa were more likely to switch ART compared to men (p < 0.001) with approximately 90% of women reporting a major change after 10 years in North America. Overall, after 8 years on ART, >50% of HIV‐ positive men and women from Southern Africa, East Africa, South and Central America remained on their original regimen. Men were more likely to have a treatment interruption compared with women in low‐ and middle‐income countries from the Asia/Pacific region (p < 0.001) as were men from Southern Africa (p < 0.001). Greater than 75% of men and women did not report a treatment interruption after 10 years on ART from all regions except North America and Southern Africa.ConclusionsThere are regional variations in the ART regimen commenced at baseline and rates of major change and treatment interruption according to sex. Some of this is likely to reflect changes in local and international antiretroviral guideline recommendations but other sex‐specific factors such as pregnancy may contribute to these differences.

AbstractIntroductionThere is paucity of data related to potential gender differences in the use of interventions to prevent and treat cardiovascular disease (CVD) among HIV‐positive individuals. We investigated whether such differences exist in the observational D:A:D cohort study.MethodsParticipants were followed from study enrolment until the earliest of death, six months after last visit or February 1, 2015. Initiation of CVD interventions [lipid‐lowering drugs (LLDs), angiotensin‐converting enzyme inhibitors (ACEIs), anti‐hypertensives, invasive cardiovascular procedures (ICPs) were investigated and Poisson regression models calculated whether rates were lower among women than men, adjusting for potential confounders.ResultsWomen (n = 12,955) were generally at lower CVD risk than men (n = 36,094). Overall, initiation rates of CVD interventions were lower in women than men; LLDs: incidence rate 1.28 [1.21, 1.35] vs. 2.40 [2.34, 2.46]; ACEIs: 0.88 [0.82, 0.93] vs. 1.43 [1.39, 1.48]; anti‐hypertensives: 1.40 [1.33, 1.47] vs. 1.72 [1.68, 1.77] and ICPs: 0.08 [0.06, 0.10] vs. 0.30 [0.28, 0.32], and this was also true for most CVD interventions when exclusively considering periods of follow‐up for which individuals were at high CVD risk. In fully adjusted models, women were less likely to receive CVD interventions than men (LLDs: relative rate 0.83 [0.78, 0.88]; ACEIs: 0.93 [0.86, 1.01]; ICPs: 0.54 [0.43, 0.68]), except for the receipt of anti‐hypertensives (1.17 [1.10, 1.25]).ConclusionThe use of most CVD interventions was lower among women than men. Interventions are needed to ensure that all HIV‐positive persons, particularly women, are appropriately monitored for CVD and, if required, receive appropriate CVD interventions.

AbstractIntroductionAlthough substitutions of antiretroviral regimen are generally safe, most data on substitutions are based on results from clinical trials. The objective of this study was to evaluate the treatment outcomes of substituting antiretroviral regimen in virologically suppressed HIV‐infected patients in non‐clinical trial settings in Asian countries.MethodsThe study population consisted of HIV‐infected patients enrolled in the TREAT Asia HIV Observational Database (TAHOD). Individuals were included in this analysis if they started combination antiretroviral treatment (cART) after 2002, were being treated at a centre that documented a median rate of viral load monitoring ≥0.8 tests/patient/year among TAHOD enrolees, and experienced a minor or major treatment substitution while on virally suppressive cART. The primary endpoint to evaluate outcomes was clinical or virological failure (VF), followed by an ART class change. Clinical failure was defined as death or an AIDS diagnosis. VF was defined as confirmed viral load measurements ≥400 copies/mL followed by an ART class change within six months. Minor regimen substitutions were defined as within‐class changes and major regimen substitutions were defined as changes to a drug class. The patterns of substitutions and rate of clinical or VF after substitutions were analyzed.ResultsOf 3994 adults who started ART after 2002, 3119 (78.1%) had at least one period of virological suppression. Among these, 1170 (37.5%) underwent a minor regimen substitution, and 296 (9.5%) underwent a major regimen substitution during suppression. The rates of clinical or VF were 1.48/100 person years (95% CI 1.14 to 1.91) in the minor substitution group, 2.85/100 person years (95% CI 1.88 to 4.33) in the major substitution group and 2.53/100 person years (95% CI 2.20 to 2.92) among patients that did not undergo a treatment substitution.ConclusionsThe rate of clinical or VF was low in both major and minor substitution groups, showing that regimen substitution is generally effective in non‐clinical trial settings in Asian countries.
