Abstract
The proportion of new HIV diagnoses among older adults aged ≥50 years continues to rise. Older adults are at higher risk of late diagnosis which is associated with higher treatment complexity and poorer health outcomes. Few studies in the Asia-Pacific region have explored factors contributing to late presentation and diagnosis in this population. Thus, our study aimed to explore factors influencing late HIV diagnosis among older adults ≥50 years in Malaysia. We conducted in-depth interviews with 16 older adults newly diagnosed with HIV (OPLWH) and focus group discussions with seven healthcare providers (HCPs) from different specialties in an academic tertiary hospital in Malaysia. All sessions were audio-recorded, transcribed verbatim and analysed thematically. Three main themes related to late diagnosis among OPLWH emerged: (1) challenge in recognizing HIV symptoms among older persons, (2) older persons and HCPs having low index of suspicion of HIV and (3) poor acceptance of HIV testing among older persons due to perceived personal and social identities. HCPs often missed HIV symptoms and these collectively culminated in OPLWH experiencing complex diagnostic journeys resulting in late HIV diagnosis. To reduce delays in HIV diagnosis, strategies are needed to improve HIV knowledge and risk perception among both older adults and HCPs.

Abstract
Availability of effective antiretroviral therapy (ART) has improved patient survival and older adults (≥50 years old) constitute 10% of the world's HIV population. However, data on this population are lacking, especially in sub-Saharan Africa. To identify the profile of older adults with HIV infection receiving ART and factors associated with viral suppression. A retrospective cross-sectional study involving HIV patients ≥50 years, registered at a University Hospital in Kumasi, Ghana from January 2010 to July 2020. All study participants had been on ARTs for ≥12 months. Data were analysed using STATA® and multivariate logistic regression was done to determine the association between variables. We recruited 132 study participants with a mean age of 58.1 years (±6.8). Non-communicable diseases (NCD) comprised the commonest comorbidity (67.4%; n = 89) and hypertension was the most prevalent (47.2%). The mean duration of ART was 63.2 months (±32.0) and approximately 84.1% (n = 111) achieved viral suppression (≤50 copies/ml). After adjustment, factors independently associated with viral suppression were widow(ed) (aOR = 0.23; 95% CI = 0.07-0.72) and good ART adherence (aOR = 3.51; 95% CI = 1.03-11.99). Hypertension is prevalent among this cohort of HIV patients. Approximately 84% of elderly patients on ARTs achieve viral suppression, influenced by widowhood and good drug adherence.

Abstract
Research on older people living with HIV (OPHIV) highlights social support as an important dimension of their resilience and coping resources. This study asks: in face of high perceived risk of HIV status disclosure, how do OPHIV cope when they have little social support from family and friends? METHODS This study broadens the study of OPHIV beyond North America and Europe and presents a case study of Hong Kong. In collaboration with the longest-running non-governmental organization working on HIV/AIDS issues in Hong Kong, 21 interviews with OPHIV were conducted. RESULTS It was found that a vast majority of them did not disclose their HIV status and many lacked social support from family and friends. The OPHIV in Hong Kong turned instead to coping through downward comparison, drawing on a comparison between their current lives with: (1) how they themselves experienced HIV in their earlier life; (2) how HIV was socially treated in the past; (3) how HIV was medically treated in the past; (4) growing up under harsh economic circumstances when industrialization and rapid economic development took place in Hong Kong; (5) Eastern religions, spiritual support and the associated philosophy of 'letting go' and acceptance. CONCLUSIONS This study has found that in face of high perceived risk of HIV status disclosure, where OPHIV have little social support from family and friends, they used the psychological mechanism of downward comparison to maintain positivity. The findings also contextualize the lives of OPHIV against the historical development of Hong Kong.

Abstract
OBJECTIVES New HIV diagnoses in persons aged > 50 years (hereafter 'older persons') are becoming more common; the clinical features and outcomes of these older individuals are poorly described. METHODS We conducted a retrospective cohort study of all new adult HIV diagnoses between October 1989 and December 2019 in southern Alberta, Canada. Differences in risk for HIV acquisition and screening, sociodemographic/clinical characteristics, and causes of death were compared between individuals younger and older than 50 years at the time of diagnosis. RESULTS New HIV diagnoses in persons > 50 years old increased from 7% in 1990 to 18% in 2019. Risk for HIV acquisition and screening reasons differed by age. Heterosexual sex (29%) was the greatest risk factor among older persons, contrasting with male same sex activity in younger persons (51%) (P < 0.001). Illness was the most common indication for testing in older persons (47%), whereas younger persons were more likely to have requested testing (34%) (P < 0.001). Relationship status differed, with 33% of older persons being married to an opposite sex partner versus 12% in younger persons (P < 0.001). Although older persons had a lower mean nadir CD4 count (132 cells/µL) than younger persons (181 cells/µL) (P < 0.001), 80% of deaths between 2010 and 2019 in the older group were attributable to non-AIDS-related causes versus 47% in younger patients. Since 2000, AIDS-related deaths and potential years of life lost have declined for both age groups. CONCLUSION The increase in new HIV diagnoses in persons aged > 50 years in southern Alberta suggests that older individuals require customized approaches for optimizing HIV diagnosis and treatment.

Abstract
OBJECTIVE Consistent condom use is still not ideal. Research showed that perceived sexual self-control is associated with greater likelihood of using condoms. However, this association seems to vary according to age and relationship agreement (i.e. non-consensual non-monogamy, NCNM vs. consensual non-monogamy, CNM). DESIGN Cross-sectional study with 307 heterosexual users of a dating web site for romantically involved individuals (81.8% men; Mage = 42.24, SD = 9.65, range: 23-76 years). All individuals were in a romantic relationship (Mlength = 13.47 years, SD = 9.39). MEASURES Demographic information, perceived sexual self-control, condom use frequency (casual sex partners; primary partner in the last 3 months) and relationship agreement. RESULTS Independently of relationship agreement, perceived sexual self-control was positively associated with condom use frequency with casual sex partners among younger and middle age participants, but not older ones (>49 years). Regarding the primary partner, a similar pattern emerged for CNM participants. In contrast, no significant association between perceived sexual self-control and condom use frequency with the primary partner emerged for NCNM individuals, regardless of age. CONCLUSION Our findings can inform evidence-based strategies to promote consistent condom use as an effective behaviour to prevent sexually transmitted infections, especially among older and NCNM individuals.

Abstract
BACKGROUND The HIV burden is increasing in older adults in the European Union (EU) and European Economic Area (EEA). We investigated factors associated with HIV diagnosis in older adults in the 31 EU/EEA countries during a 12 year period. METHODS In this analysis of surveillance data, we compared data from older people (aged ≥50 years) with those from younger people (aged 15-49 years). We extracted new HIV diagnoses reported to the European Surveillance System between Jan 1, 2004, and Dec 31, 2015, and stratified them by age, sex, migration status, transmission route, and CD4 cell count. We defined late diagnosis as CD4 count of less than 350 cells per μL at diagnosis and diagnosis with advanced HIV disease as less than 200 cells per μL. We compared the two age groups with the χ2 test for difference, and used linear regression analysis to assess temporal trends. FINDINGS During the study period 54 102 new HIV diagnoses were reported in older adults. The average notification rate of new diagnoses was 2·6 per 100 000 population across the whole 12 year period, which significantly increased over time (annual average change [AAC] 2·1%, 95% CI 1·1-3·1; p=0·0009). Notification rates for new HIV diagnoses in older adults increased significantly in 16 countries in 2004-15, clustering in central and eastern EU/EEA countries. In 2015, compared with younger adults, older individuals were more likely to originate from the reporting country, to have acquired HIV via heterosexual contact, and to present late (p<0·0001 for all comparisons). HIV diagnoses increased significantly over time among older men (AAC 2·2%, 95% CI 1·2-3·3; p=0·0006), women (1·3%, 0·2-2·4; p=0·025), men who have sex with men (5·8%, 4·3-7·5; p<0·0001), and injecting drug users (7·4%, 4·8-10·2; p<0·0001). INTERPRETATION Our findings suggest that there is a compelling need to deliver more targeted testing interventions for older adults and the general adult population, such as by increasing awareness among health-care workers and expanding opportunities for provider-initiated and indicator-condition-guided testing programmes.

Abstract
BACKGROUND In sub-Saharan Africa, few studies exist on elderly HIV-positive populations. Therefore, we aimed to examine the profiles of elderly people living with HIV (PLHIV) in Burkina Faso and their response to antiretroviral therapy (ART). METHODS We reviewed the monitoring and treatment of PLHIV over the age of 50 years and then compared with the monitoring and treatment of PLHIV under 50 years. RESULTS A total of 3367 patients were included. The median age of elderly people was 54.5 years and of young people was 34.9 years ( P = .03). In both the groups, screening was performed following clinical suspicion (64.9% in elderly versus 56% in young people; P < .001). Cardiovascular risk factors were generally more significant in the elderly people. The risk of death while on ART was 2.3 times higher in elderly people ( P < .001). CONCLUSION HIV infection in older people occurs in those who already have some cardiovascular risk factors. Particular attention should be given to multidisciplinary care for the elderly individuals.

Abstract
BACKGROUND In view of the maturing HIV epidemic in sub-Saharan Africa, better understanding of its epidemiology among older adults is necessary in order to design appropriate care and treatment programmes for them. OBJECTIVES To describe the demographic and epidemiological characteristics of HIV opportunistic infections among newly enrolled patients aged 50 years and above in Ibadan, South-West Nigeria. METHODS Analysis of data extracted from electronic records of 17, 312 subjects enrolled for HIV/AIDS care and treatment between January 2006 and December 2014 at the ART clinic, University College Hospital, Ibadan. RESULTS Age of the patients ranged from 18 to 90 years with a mean of 36.4 years (SD= 10.3) with older adults constituting 12.0% (2075). Among older adults, about half (52.9%) were females. Majority (59.1%) were currently married while 25.9% were widowed. Prevalence of opportunistic infections was 46.6%. The commonest opportunistic infections (OIs) were: oral candidiasis (27.6%), chronic diarrhoea (23.5% and peripheral neuropathy (14.8%). Significant factors associated with opportunistic infections in older adults were: CD4 count less than 350 (OR=3.12, CI: 2.29-4.25) and hepatitis C virus co-infection (OR=2.17, CI: 1.14-4.13). CONCLUSION There is need for prompt response to the peculiar challenges associated with the emerging shift in the epidemiology of HIV and associated infections in sub-Saharan Africa.

Abstract
BACKGROUND Increased evidence of relevant HIV-1 epidemic transmission in European countries is being reported, with an increased circulation of non-B-subtypes. Here, we present two recent HIV-1 non-B transmission clusters characterized by NNRTI-related amino-acidic mutations among newly diagnosed HIV-1 infected men, living in Rome (Central-Italy). METHODS Pol and V3 sequences were available at the time of diagnosis for all individuals. Maximum-Likelihood and Bayesian phylogenetic-trees with bootstrap and Bayesian-probability supports defined transmission-clusters. HIV-1 drug-resistance and V3-tropism were also evaluated. RESULTS Among 534 new HIV-1 non-B cases, diagnosed from 2011 to 2014, in Central-Italy, 35 carried virus gathering in two distinct clusters, including 27 HIV-1 C and 8 CRF17_BF subtypes, respectively. Both clusters were centralized in Rome, and their origin was estimated to have been after 2007. All individuals within both clusters were males and 37.1% of them had been recently-infected. While C-cluster was entirely composed by Italian men-who-have-sex-with-men, with a median-age of 34 years (IQR:30-39), individuals in CRF17_BF-cluster were older, with a median-age of 51 years (IQR:48-59) and almost all reported sexual-contacts with men and women. All carried R5-tropic viruses, with evidence of atypical or resistance amino-acidic mutations related to NNRTI-drugs (K103Q in C-cluster, and K101E+E138K in CRF17_BF-cluster). CONCLUSIONS These two epidemiological clusters provided evidence of a strong and recent circulation of C and CRF17_BF strains in central Italy, characterized by NNRTI-related mutations among men engaging in high-risk behaviours. These findings underline the role of molecular epidemiology in identifying groups at increased risk of HIV-1 transmission, and in enhancing additional prevention efforts.

Abstract
Background Rising HIV infection rates have been observed among elderly people in Guangxi, China. Inexpensive aphrodisiacs are available for purchase in suburban and rural areas. This study aims to investigate the association between aphrodisiac use and increased HIV risk for middle-aged and elderly men in Guangxi. Methods A matched case-control study of aphrodisiac use-associated HIV infection was performed among male subjects over 50 years old who were clients of low-cost commercial sex venues in Guangxi. The cases were defined as clients who were HIV-positive and two controls were selected for each case. The cases and the controls were matched on the visited sex venue, age (±3 years), number of years of purchasing sex (±3 years), and educational attainment. Subjects were interviewed and tested for HIV. Paired t-test or McNemar Chi-squared test were used to compare the characteristics between the cases and controls. A stepwise conditional logistic regression was used to identify risk factors associated with HIV infection. Findings This study enrolled 103 cases and 206 controls. Aphrodisiac use (P = 0.02, odds ratio (OR) = 1.81, 95% CI = 1.08–3.04), never using condom during commercial sex encounter (P = 0.03, odds ratio (OR) = 1.82, 95% CI = 1.08–3.07), and lacking a stable partner (P = 0.03, odds ratio (OR) = 1.76, 95% CI = 1.05–2.98) were found to be risk factors for HIV infection among the study groups. For subjects reporting aphrodisiac use, the frequency of purchasing sex was positively correlated with the frequency of aphrodisiac use (r = 0.3; p = 0.02). Conclusions Aphrodisiac use was significantly associated with increased HIV infection risk in men over 50 years old who purchased commercial sex in the suburban and rural areas of Guangxi. Further research and interventions should address the links between aphrodisiac use, commercial sex work, condom use, and increased HIV transmission.

Abstract
The literature pertaining to the elderly shows that HIV infection among this population is on the increase, suggesting that the elderly population engages in activities risky for HIV infection. Reports on such behaviour include frequent sexual relations with much younger people and having multiple partners. A study was carried out in Ga-Rankuwa, a black township in Gauteng Province, South Africa to explore and describe the understanding of these elderly people regarding their risks of HIV infection and AIDS. Using a qualitative, exploratory design, three focus-group interviews were conducted with 32 women aged over 50 years. Findings revealed that older persons have knowledge about transmission of HIV infection and AIDS. However, a few had misconceptions as to how HIV infection is transmitted, as they believed that poor nutrition and sharing facilities play a role. Knowledge of mechanisms of protecting themselves against infection, such as use of a condom during coitus and wearing gloves when caring for infected family members, was also evident. The elderly indicated that they would prefer an older person, who they could identify with, to educate them more about HIV infection and AIDS. Although majority of participants had knowledge of how HIV is transmitted, and issues that put them at risk of transmission, a few the older persons had misconceptions about how HIV is transmitted due to lack of knowledge, as they believed that poor nutrition and sharing facilities can transmit infection. The lack of knowledge underscores the importance of addressing sexual risk with older people. It was very clear that more needs to be done in terms of education campaigns to dispel the myths of HIV infection and to empower the elderly.

Abstract
Background The increasing number of people living with HIV aged 50 years and older has been recognised around the world yet non-pharmacologic HIV behavioural and cognitive interventions specifically targeted to older adults are limited. Evidence is needed to guide the response to this affected group. Methods We conducted a systematic review of the available published literature in MEDLINE, Embase and the Education Resources Information Center. A search strategy was defined with high sensitivity but low specificity to identify behavioural interventions with outcomes in the areas of treatment adherence, HIV testing uptake, increased HIV knowledge and uptake of prevention measures. Data from relevant articles were extracted into excel. Results Twelve articles were identified all of which originated from the Americas. Eight of the interventions were conducted among older adults living with HIV and four for HIV-negative older adults. Five studies included control groups. Of the included studies, four focused on general knowledge of HIV, three emphasised mental health and coping, two focused on reduced sexual risk behaviour, two on physical status and one on referral for care. Only four of the studies were randomised controlled trials and seven – including all of the studies among HIV-negative older adults – did not include controls at all. A few of the studies conducted statistical testing on small samples of 16 or 11 older adults making inference based on the results difficult. The most relevant study demonstrated that using telephone-based interventions can reduce risky sexual behaviour among older adults with control reporting 3.24 times (95% CI 1.79-5.85) as many occasions of unprotected sex at follow-up as participants. Overall however, few of the articles are sufficiently rigorous to suggest broad replication or to be considered representative and applicable in other settings. Conclusions More evidence is needed on what interventions work among older adults to support prevention, adherence and testing. More methodological rigourised needed in the studies targeting older adults. Specifically, including control groups in all studies is needed as well as sufficient sample size to allow for statistical testing. Addition of specific bio-marker or validated behavioural or cognitive outcomes would also strengthen the studies.

Abstract
Aiming to explore universal HIV testing, and to understand the exact HIV prevalence in the older general population, we conducted a community-based cross-sectional epidemiological investigation in two counties of Zhejiang province, China. Using census strategy and convenience sampling method, those participants who were older than 50 years and met eligibility criteria were enrolled, and HIV prevalence was presented as a crude infection rate. A total of 215,441 (64.82%) were enrolled into this study, HIV testing was added into their health exam plan and 18 were confirmed as HIV positive, giving a crude rate of 0.84/10,000. HIV prevalence was higher among men than among women in all age groups (p < 0.05). Unlike previous research, 14 cases (78%) still had a relatively high CD4 + count; 17 cases (94%) had been infected by sexual transmission. Active large-scale HIV screening by integrating into routine health care can be an effective strategy to find people living with HIV at relative early stage of disease.

Abstract
Objective The aims of this study were to systematically review epidemiological characteristics in older people living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (PLWHA) in low endemic areas of the People’s Republic of China, analyze the causes of death and mortality, and provide a basis for targeted prevention in these populations. Methods Nine counties representative of the distribution and epidemiological factors of the HIV epidemic in Zhejiang Province were selected, and data from 1,115 HIV-positive individuals, including 196 older people (≥50 years), who were confirmed as PLWHA from January 1, 2000 to December 31, 2012, were retrospectively analyzed. Results The proportion of older PLWHA increased from 0% in 2000 to 22.45% in 2012. Sexual transmission was the main route, accounting for 82.65% of infections in this group. Compared with the younger group (range from 14 to 49 years old), the older group had significantly lower CD4+ cell counts (291.64 versus 363.63; P<0.001) when first diagnosed, and more of this group presented in the AIDS state with opportunistic infections (51.02% versus 34.06%; P<0.001). In the older group, 25 (12.76%) patients died directly of AIDS and 171 (87.24%) were censored, and in the younger group 50 (5.44%) patients died directly of AIDS and 869 (94.56%) were censored. Estimated survival time since HIV diagnosis in the older group was 11.54±0.49 years (95% confidence interval [CI] 10.59–12.50), while in the younger group it was 13.85±0.46 years (95% CI 12.94–14.76), the log rank (Mantel–Cox) test gave a chi-square value of 3.83, and there was significant difference between the groups (P<0.05). Conclusion The number of older PLWHA increased steadily over the study period in low HIV endemic provinces of a developing country. Later discovery and preexisting disease perhaps contributed to a shorter estimated survival time for older PLWHA and higher mortality.

Abstract
OBJECTIVES Combination antiretroviral therapy (cART) has become the main driver of total costs of caring for persons living with HIV (PLHIV). The present study estimated the short/medium-term cost trends in response to the recent evolution of national guidelines and regional therapeutic protocols for cART in Italy. METHODS We developed a deterministic mathematical model that was calibrated using epidemic data for Lazio, a region located in central Italy with about six million inhabitants. RESULTS In the Base Case Scenario, the estimated number of PLHIV in the Lazio region increased over the period 2012-2016 from 14 414 to 17 179. Over the same period, the average projected annual cost for treating the HIV-infected population was €147.0 million. An earlier cART initiation resulted in a rise of 2.3% in the average estimated annual cost, whereas an increase from 27% to 50% in the proportion of naïve subjects starting cART with a nonnucleoside reverse transcriptase inhibitor (NNRTI)-based regimen resulted in a reduction of 0.3%. Simplification strategies based on NNRTIs co-formulated in a single tablet regimen and protease inhibitor/ritonavir-boosted monotherapy produced an overall reduction in average annual costs of 1.5%. A further average saving of 3.3% resulted from the introduction of generic antiretroviral drugs. CONCLUSIONS In the medium term, cost saving interventions could finance the increase in costs resulting from the inertial growth in the number of patients requiring treatment and from the earlier treatment initiation recommended in recent guidelines.

Abstract
Background The aim of our work was to evaluate the potential impact of the European policy of testing for HIV all individuals presenting with an indicator disease, to prevent late diagnosis of HIV. We report on a retrospective analysis among individuals diagnosed with HIV to assess whether a history of certain diseases prior to HIV diagnosis was associated with the chance of presenting late for care, and to estimate the proportion of individuals presenting late who could have been diagnosed earlier if tested when the indicator disease was diagnosed. Methods We studied a large cohort of individuals newly diagnosed with HIV infection in 13 counselling and testing sites in the Lazio Region, Italy (01/01/2004-30/04/2009). Considered indicator diseases were: viral hepatitis infection (HBV/HCV), sexually transmitted infections, seborrhoeic dermatitis and tuberculosis. Logistic regression analysis was performed to estimate association of occurrence of at least one indicator disease with late HIV diagnosis. Results In our analysis, the prevalence of late HIV diagnosis was 51.3% (890/1735). Individuals reporting at least one indicator disease before HIV diagnosis (29% of the study population) had a lower risk of late diagnosis (OR = 0.7; 95%CI: 0.5-0.8) compared to those who did not report a previous indicator disease. 52/890 (5.8%) late presenters were probably already infected at the time the indicator disease was diagnosed, a median of 22.6 months before HIV diagnosis. Conclusions Our data suggest that testing for HIV following diagnosis of an indicator disease significantly decreases the probability of late HIV diagnosis. Moreover, for 5.5% of late HIV presenters, diagnosis could have been anticipated if they had been tested when an HIV indicator disease was diagnosed. However, this strategy for enhancing early HIV diagnosis needs to be complemented by client-centred interventions that aim to increase awareness in people who do not perceive themselves as being at risk for HIV.

Abstract
The worldwide elderly population is expected to grow by an additional 694 million people by 2025. By that time, there will be approximately two billion elderly people in the world, most of whom (80%) will be living in developing countries. Based on recent estimates, this population will number over 40 million in 2030 in Brazil and a consequent increase in governmental spending for this population can be expected. Since highly active antiretroviral therapy became available in the mid-1990s, the life expectancy of people living with HIV has increased significantly. Approximately 12 million life years were added to the world between 1996 and 2008 as a consequence of wider access to highly active antiretroviral therapy. In Brazil, the incidence of AIDS among the population aged ≥50 years doubled between 1996 and 2006. The development of antiretroviral therapy has allowed individuals diagnosed at a younger age to live longer, which partially explains the aging tendency associated with the HIV/AIDS epidemic. It is estimated that by 2015, subjects aged ≥50 years will represent 50% of the people living with HIV undergoing clinical treatment. This scenario presents some challenges, including the fact that the diagnosis of HIV tends to be delayed in older patients compared to younger patients because the symptoms of HIV can be confused with those of other common diseases among the elderly and also because healthcare professionals do not consider this population to be at high risk for HIV infection. In regard to the individuals diagnosed with HIV, a further challenge is presented by the morbidity normally associated with aging. Finally, the elderly also exhibit higher susceptibility to the toxic effects and pharmacological interactions of medications. The present article reviews the literature regarding the profile of HIV infection among individuals aged ≥50 years focusing on practical features related to the clinical approach and long-term follow-up of this population.

Abstract
OBJECTIVES HIV prevalence among older people is on the increase. The aim of this study was to evaluate the epidemiological and clinical features at diagnosis and survival of older patients. METHODS This was a retrospective analysis of the data of 558 newly diagnosed antiretroviral-naïve patients between January 1998 and December 2008. Patients were divided into two groups according to their age at diagnosis: ≥50 years (n=103) and 18-49 years (n=455). RESULTS The most common risk factor for older patients was heterosexual contact (p<0.013). Older patients were more likely to suffer from hypertension (33.0% vs. 5.1%, p<0.0005), cardiovascular disease (20.4% vs. 2.9%, p<0.0005), neurological disorders (11.7% vs. 5.5%, p=0.02), renal dysfunction (12.6% vs. 5.3%, p=0.01), and infections (66.0% vs. 49.7%, p=0.003) than their younger counterparts, and to have more hospital admissions during follow-up (47.5% vs. 19.6%, p<0.0005). Older patients had a shorter survival time (p<0.0005). A statistically significant increase in CD4+ cell number through time was observed in both groups (p<0.0005). Younger patients reached higher magnitudes of absolute numbers of CD4+ cells during follow-up (p<0.0005) after the initiation of antiretroviral therapy. The total number of patients with clinical AIDS from baseline throughout the study period was also higher in the older age group (35.9% vs. 25.0%). CONCLUSIONS HIV-infected people aged ≥50 years differ in epidemiological and clinical features to younger HIV-infected people. The issue of increasing prevalence of HIV infection is a matter of concern due to existing comorbidities, which probably lead to higher mortality rates and faster progression to clinical AIDS.

Abstract
The introduction of highly active antiretroviral therapy during the 1990s was crucial to the decline in the rates of morbidity and death related to the acquired immunodeficiency syndrome (AIDS) and turned human immunodeficiency virus (HIV) infection into a chronic condition. Consequently, the HIV/AIDS population is becoming older. The aim of this study was to describe the immunological, clinical and comorbidity profile of an urban cohort of patients with HIV/AIDS followed up at Instituto de Pesquisa Clinica Evandro Chagas, Oswaldo Cruz Foundation in Rio de Janeiro, Brazil. Retrospective data from 2307 patients during January 1st, 2008 and December 31st, 2008 were collected. For continuous variables, Cuzick's non-parametric test was used. For categorical variables, the Cochran–Armitage non-parametric test for tendency was used. For all tests, the threshold for statistical significance was set at 5%. In 2008, 1023 (44.3%), 823 (35.7%), 352 (15.3%) and 109 (4.7%) were aged 18–39, 40–49, 50–59 and ≥60 years-old, respectively. Older and elderly patients (≥40 years) were more likely to have viral suppression than younger patients (18–39 years) (p < 0.001). No significant difference in the latest CD4+ T lymphocyte count in the different age strata was observed, although elderly patients (≥ 50 years) had lower CD4+ T lymphocyte nadir (p < 0.02). The number of comorbidities increased with age and the same pattern was observed for the majority of the comorbidities, including diabetes mellitus, dyslipidemia, hypertension, cardiovascular diseases, erectile dysfunction, HCV, renal dysfunction and also for non-AIDS-related cancers (p < 0.001). With the survival increase associated to successful antiretroviral therapy and with the increasing new infections among elderly group, the burden associated to the diagnosis and treatment of the non-AIDS related HIV comorbidities will grow. Longitudinal studies on the impact of aging on the HIV/AIDS population are still necessary, especially in resource-limited countries.

Abstract
The age of 50 has been considered as a cut-off to discriminate older subjects within HIV-infected people according to the Centers for Disease Control and Prevention (CDC). However, the International AIDS Society (IAS) mentions 60 years of age and the Department of Health and Human Services (DHHS) makes no consideration. We aimed to establish an age cut-off that could differentiate response to highly active antiretroviral therapy (HAART) and, therefore, help to define advanced age in HIV-infected patients. CoRIS is an open, prospective, multicenter cohort of HIV adults naive to HAART at entry (January 2004 to October 2009). Survival, immunological response (IR) (CD4 increase of more than 100 cell/ml), and virological response (VR) (HIV RNA less than 50 copies/ml) were compared among 5-year age intervals at start of HAART using Cox proportional hazards models, stratified by hospital and adjusted for potential confounders. Among 5514 patients, 2726 began HAART. During follow-up, 2164 (79.4%) patients experienced an IR, 1686 (61.8%) a VR, and 54 (1.9%) died. Compared with patients aged <25 years at start of HAART, those aged 50-54, 55-59, 60-64, 65-59, and 70 or older were 32% (aHR: 0.68, 95% CI: 0.52-0.87), 29% (aHR: 0.71, 95% CI: 0.53-0.96), 34% (aHR: 0.66, 95% CI: 0.46-0.95), 39% (aHR: 0.61, 95% CI: 0.37-1.00), and 43% (aHR: 0.57, 95% CI: 0.31-1.04) less likely to experience an IR. The VR was similar across all age groups. Finally, patients aged 50-59 showed a 3-fold increase (aHR: 3.58; 95% CI: 1.07-11.99) in their risk of death compared to those aged <30 years. In HIV infection, patients aged ≥50 years have a poorer immunological response to HAART and a poorer survival. This age could be used to define medically advanced age in HIV-infected people.

Abstract
BACKGROUND Thirteen percent of the U.S. population is ages 65 and older, a number projected to reach 20% by 2030. By 2015, 50% of Human Immunodeficiency Virus (HIV)-infected individuals in the U.S. are expected to be ages 50 and older. Current Centers for Disease Control and Prevention guidelines recommend "opt-out" HIV screening for individuals ages 13-64. The purpose of this study was to assess the occurrence and barriers to HIV screening in older adults, and to evaluate the rationale for expanding routine HIV screening to this population. METHODS The study used 2009 National Health Interview Survey (NHIS) data. A total of 12,366 (unweighted) adults, ages 50 and older, participated in the adult section of the NHIS and answered questions on the HIV/AIDS, Sexually Transmitted Diseases, and Tuberculosis components. Associations between HIV screening, socio-demographic variables, and knowledge of HIV-related disease were examined using logistic regression models. RESULTS The HIV screening rate within this population was 25.4%. Race had no statistically significant effect. Low risk perception of HIV exposure (84.1%) accounted for low likelihood of planned screening (3.5%) within 12 months post survey. A routine medical check-up was the single most common reason for HIV screening (37.6%), with only about half (52.7%) of the tests suggested by a health care provider. CONCLUSION It is imperative that practices and policies are developed and implemented to increase HIV awareness and screening in the older adult population. Increased health care provider awareness of the importance of HIV screening, especially for those 65 and older, is critical. Health policies and clinical guidelines should be revised to promote and support screening of all adults.

Abstract
BACKGROUND The application of serological methods in HIV/AIDS routine surveillance systems to identify persons with recently acquired HIV infection has been proposed as a tool which may provide an accurate description of the current transmission patterns of HIV. Using the information about recent infection it is possible to estimate HIV incidence, according to the model proposed by Karon et al. in 2008, that accounts for the effect of testing practices on the number of persons detected as recently infected. METHODS We used data from HIV/AIDS surveillance in the period 2004-2008 to identify newly diagnosed persons. These were classified with recent/non-recent infection on the basis of an avidity index result, or laboratory evidence of recently acquired infection (i.e., previous documented negative HIV test within 6 months; or presence of HIV RNA or p24 antigen with simultaneous negative/indeterminate HIV antibody test). Multiple imputation was used to impute missing information. The incidence estimate was obtained as the number of persons detected as recently infected divided by the estimated probability of detection. Estimates were stratified by calendar year, transmission category, gender and nationality. RESULTS During the period considered 3,633 new HIV diagnoses were reported to the regional surveillance system. Applying the model, we estimated that in 2004-2008 there were 5,465 new infections (95%CI: 4,538-6,461); stratifying by transmission category, the estimated number of infections was 2,599 among heterosexual contacts, 2,208 among men-who-have-sex-with-men, and 763 among injecting-drug-users. In 2008 there were 952 (625-1,229) new HIV infections (incidence of 19.9 per 100,000 person-years). In 2008, for men-who-have-sex-with-men (691 per 100,000 person-years) and injecting drug users (577 per 100,000 person-years) the incidence remained comparatively high with respect to the general population, although a decreasing pattern during 2004-2008 was observed for injecting-drug-users. CONCLUSIONS These estimates suggest that the transmission of HIV infection in Lazio remains frequent and men-who-have-sex-with men and injecting-drug-users are still greatly affected although the majority of new infections occurs among heterosexual individuals.

Abstract
OBJECTIVE To quantify the number of cases and prevalence of human immunodeficiency virus (HIV) infection among older adults in sub-Saharan Africa. METHODS We reviewed data from Demographic and Health Surveys (DHS). Although in these surveys all female respondents are < 50 years of age, 18 of the surveys contained data on HIV infection among men aged ≥ 50 years. To estimate the percentage of older adults (i.e. people ≥ 50 years of age) who were positive for HIV (HIV+), we extrapolated from data from the Joint United Nations Programme on HIV/AIDS on the estimated number of people living with HIV and on HIV infection prevalence among adults aged 15-49 years. FINDINGS In 2007, approximately 3 million people aged ≥ 50 years were living with HIV in sub-Saharan Africa. The prevalence of HIV infection in this group was 4.0%, compared with 5.0% among those aged 15-49 years. Of the approximately 21 million people in sub-Saharan Africa aged ≥ 15 years that were HIV+, 14.3% were ≥ 50 years old. CONCLUSION To better reflect the longer survival of people living with HIV and the ageing of the HIV+ population, indicators of the prevalence of HIV infection should be expanded to include people > 49 years of age. Little is known about comorbidity and sexual behaviour among HIV+ older adults or about the biological and cultural factors that increase the risk of transmission. HIV services need to be better targeted to respond to the growing needs of older adults living with HIV.

Abstract
Medical advances continue to change the face of human immunodeficiency virus- acquired immunodeficiency syndrome (HIV/AIDS). As life expectancy increases, the number of people living with HIV rises, presenting new challenges for the management of a chronic condition. Aging, nutrition, and physical activity can influence outcomes in other chronic conditions, and emerging data show that each of these factors can impact viral replication and the immune system in HIV. HIV infection results in a decline of the immune system through the depletion of CD4+ T cells. From initial infection, viral replication is a continuous phenomenon. Immunosenescence, a hallmark of aging, results in an increased susceptibility to infections secondary to a delayed immune response, and this phenomenon may be increased in HIV-infected patients. Optimal nutrition is an important adjunct in the clinical care of patients with HIV. Nutritional interventions may improve the quality and span of life and symptom management, support the effectiveness of medications, and improve the patient's resistance to infections and other disease complications by altering immunity. Moderate physical activity can improve many immune parameters, reduce the risk of acute infection, and combat metabolic abnormalities. As people with HIV age, alternative therapies such as nutrition and physical activity may complement medical management.

Abstract
OBJECTIVES Describe the epidemiology and impact of late diagnosis among older adults living with HIV and estimate age at infection. METHODS Comparative national analyses between individuals diagnosed when aged 50 years and over with individuals diagnosed prior to 50 years. Age at infection was estimated using CD4 cell count at diagnosis. RESULTS A total of 8255 older adults accessed HIV care in England, Wales and Northern Ireland in 2007, a 3.5-fold increase compared to 2000; with one in 10 individuals newly diagnosed in 2007. When compared with younger adults at diagnosis, older adults were significantly more likely to be men (74 vs. 58%; P < 0.001), infected through sex between men (40 vs. 34%; P < 0.001) and of white ethnicity (60 vs. 38%; P < 0.001). Older heterosexual adults were more likely to be infected within the UK (16 vs. 12%; P < 0.001), with evidence of travel abroad among white heterosexual men. Almost half (48%) of older adults were late presenters vs. a third (33%) of younger adults. Older late presenters were 14 times more likely to die within a year of diagnosis compared with older adults who were not diagnosed late (14 vs. 1%; P < 0.001) and had 2.4 times the risk of dying than younger late presenters. We estimate that nearly half (48%) of older adults diagnosed between 2000 and 2007 acquired their infection at age 50 and over. CONCLUSION Our study provides evidence of HIV transmission, high rates of late presentation and an increased risk of short-term mortality among older adults. These findings highlight the need for increased targeted prevention efforts and strategies to increase HIV testing among older adults at risk of HIV.

Abstract
BACKGROUND Clinicians caring for HIV-infected patients >60 years old encounter multiple clinical challenges. The use of a functional geriatrics screening for detection of significant comorbidities is important in this population. METHODS The geriatrics screening evaluated functional capabilities, depression, cognitive dysfunction, nutrition, mobility, medicines used, and interactions. RESULTS As of July 2009, 57 patients were screened (average age 62.6, 39 males and 18 females). A total of 17 patients (9 males and 8 females) were referred to the geriatrics/HIV program because of identified problems in multiple domains: 10 with cognitive dysfunction, 8 with problems in basic or instrumental activities of daily living, 6 with nutritional issues, 5 with depression, 5 with mobility problems, 4 with visual issues, and 2 with hearing difficulties. The average age was 62.9. Median CD4 count and viral load were 285 (15-714) cells/mm(3) and 30 505 copies/mL (0-407 697), respectively. CONCLUSIONS The functional yearly screening of patients >60 years with HIV needs to be part of regular care of patients infected with HIV as multiple functional problems can be diagnosed and addressed.

Abstract
OBJECTIVE The aim of the study was to report on HIV and older people in the European Region, including new data stratified by subregion and year. METHODS Data were collected from the 2008 World Health Organization Regional Office for Europe, Communicable Diseases Unit survey on HIV/AIDS and health systems. RESULTS It was found that 12.9% of newly reported cases of HIV infection in Western Europe in 2007 were in people aged 50 years or older. In Central Europe, almost one-in-10 newly reported cases of HIV infection were in older people, while the proportion in Eastern Europe was 3.7% in 2007. CONCLUSIONS The issue of HIV infection among older people is of increasing concern as more people age with HIV infection as a result of the availability of combination antiretroviral therapy.

Abstract
BACKGROUND The transmission of HIV-1 drug-resistant strains in drug naive patients may seriously compromise the efficacy of a first-line antiretroviral treatment. To better define this problem, a study in a cohort of newly diagnosed HIV-1 infected individuals has been conducted. This study is aimed to assess the prevalence and the patterns of the mutations recently associated with transmitted drug resistance in the reverse transcriptase (RT) and in protease (PR) of HIV-1. METHODS Prevalence of transmitted drug resistant strains is determined in 255 newly diagnosed HIV-1 infected patients enrolled in different counselling and testing (CT) centres in Central Italy; the Avidity Index (AI) on the first available serum sample is also used to estimate time since infection. Logistic regression models are used to determine factors associated with infection by drug resistant HIV-1 strains. RESULTS The prevalence of HIV-1 strains with at least one major drug resistance mutation is 5.9% (15/255); moreover, 3.9% (10/255) of patients is infected with HIV nucleoside reverse transcriptase inhibitor (NRTI)-resistant viruses, 3.5% (9/255) with HIV non-NRTI-resistant viruses and 0.4% (1/255) with HIV protease inhibitor (PI)-resistant viruses. Most importantly, almost half (60.0%) of patients carries HIV-1 resistant strains with more than one major drug resistance mutation. In addition, patients who had acquired HIV through homosexual intercourses are more likely to harbour a virus with at least one primary resistance mutation (OR 7.7; 95% CI: 1.7-35.0, P = 0.008). CONCLUSION The prevalence of drug resistant HIV-1 strains among newly diagnosed individuals in Central Italy is consistent with the data from other European countries. Nevertheless, the presence of drug-resistance HIV-1 mutations in complex patterns highlights an additional potential risk for public health and strongly supports the extension of wide genotyping to newly diagnosed HIV-1 infected patients.

Abstract
BACKGROUND The proportion of older people is increasing worldwide. Globally, it is estimated that older people (those 60 years or older) constitute more than 11% of the population. As the HIV/AIDS pandemic rages in sub-Saharan Africa (SSA), its impact on older people needs closer attention given the increased economic and social roles older people have taken on as a result of increased mortality among adults in the productive age groups. Few studies have looked at older people and their health in SSA or indeed the impact of HIV/AIDS on their health. This study aims to assess the effect of being directly or indirectly affected by HIV/AIDS on the health of older people in two Nairobi slums. METHODS Data were collected from residents of the Nairobi Urban Health and Demographic Surveillance area aged 50 years and above on 1st October 2006. Health status was assessed using the short SAGE (Study on Global AGEing and Adult Health) form and two outcome measures--self-rated health and a composite health score--were generated. To assess HIV/AIDS affected status, respondents were asked: Have you personally been affected by HIV/AIDS? If yes, a follow up question: "How have you been personally affected by HIV/AIDS?" was asked. Ordinallogistic regression was used in models with self-rated health and linear regression in models with the health score. RESULTS About 18% of respondents reported being affected by HIV/AIDS in at least one way, although less than 1% reported being infected with HIV. Nearly 60% of respondents reported being in good health, 27% in fair health and 14% in poor health. The overall mean health score was 70.6 (SD: 13.9) with females reporting worse health outcomes than males. Respondents directly or indirectly affected by HIV/AIDS reported worse health outcomes than those not affected: mean health score: 68.5 and 71.1 respectively (t = 3.21, p = 0.0007), and an adjusted odds ratio of reporting poor health of 1.42 (95%CI: 1.12-1.80). CONCLUSION Poor health outcomes among older people affected by HIV/AIDS highlight the need for policies that target them in the fight against HIV/AIDS if they are to play their envisaged care giving and other traditional roles.

Abstract
OBJECTIVE The aim of this study is to characterize the ways in which older HIV-infected people differ from younger HIV-infected people. METHODS Prospective cohort study. PISCIS cohort includes newly attended HIV-infected subjects since January 1, 1998. Naive patients were selected. Two groups were defined: G1 (>or=50 years at time of diagnosis, n=493) and G2 (18-49 years, n=4511). Statistical analysis was performed using chi(2), Student's t test, Cox regression and linear mixed models. RESULTS G1 had different features: males (G1: 84% vs. G2: 75%, p<0.001), sexual transmission (52% vs. 32%, p<0.001), AIDS at first visit (38% vs. 22%, p<0.001). The follow-up was 6 years. Ninety-five percent of patients in G1 and 92% in G2 presented a detectable viral load (>or=500 copies/mm(3)) at the first visit (p=0.016). G1 presented lower CD4 levels with respect to G2 throughout the period but the increase of CD4 in G1 at the end of the study period was 254 cells/mm(3) whereas for G2 it was 196 cells/mm(3) (p<0.001). Mortality was 9% for G1 and 4% for G2 (p<0.001). CONCLUSIONS HIV-infected people diagnosed at the age of 50 years or older showed different features. They showed good viral and immunological response to HAART.
