Increasing proportion of AIDS diagnoses among older adults in Italy

The Lived Experience of a Newly Diagnosed Older Person With HIV in Ukraine

Low- and middle-income countries are home to 80% of older people with HIV (OPWH). Ukrainian OPWH experience higher mortality and decreased antiretroviral therapy (ART) initiation than younger patients, but there is little data examining OPWH's perspectives around new diagnosis and impact on care. In this study, we examined accounts of 30 newly diagnosed OPWH in Ukraine, exploring challenges faced in the peri-diagnosis period. Themes emerged representing the longitudinal coping process: OPWH (1) viewed themselves as low risk before diagnosis; (2) experienced HIV diagnosis as a traumatic event challenging their self-image; (3) used disclosure to seek support among a small circle of family, friends, or health care providers; (4) avoided disclosure to outsiders including primary care providers for fears of stigma and breaches in confidentiality; (5) viewed age as an asset; and (6) used HIV diagnosis as starting point for growth. These findings highlight the need for age-specific programming to increase HIV knowledge and coping, increase screening, and improve long-term planning.

Kaposi sarcoma incidence, survival and trends: Data from the information network on rare cancers in Europe (RARECAREnet)

BACKGROUND

This study provides updated information on Kaposi sarcoma (KS) in Europe during 1995-2007 from the RARECARENet project.

METHODS

Data comes from 59 population-based cancer registries in 22 countries. KS was defined as ICD-O-3 morphology code 9140 combined with any topography code. Crude and age-adjusted incidence rates and relative survival for years of diagnosis 2000-2007 and with trends during 1995-2007 were calculated overall, by age and by country.

RESULTS

The crude annual incidence rate was 0.28 per 100,000 and age-adjusted incidence was 0.23 per 100,000; incidence increased with age, from 0.18/100,000 at age 0-44 to 0.25/100,000 at age 45-64 and 0.69/100,000 at age 65 and over. Age-adjusted incidence in males was more than four times that in females. Portugal, which had the highest incidence of AIDS in Europe, had by far the highest incidence of KS at age 0-44, 1.44/100,000, more than four times the rate in any other country. Incidence among males in Europe aged 0-44 fell significantly between 1995-1998 and 1999-2002, followed by a significant increase in 2003-2007. Younger patients, with predominantly AIDS-related KS, formerly had a worse prognosis, but since 1999-2001 5-year relative survival increased for patients aged under 65, and by 2005-2007 was 83-86 % for all three age groups 0-44, 45-64, and 65 and over.

CONCLUSION

Survival and quality of life for the increasing number of people in Europe affected by KS should improve further following the development of evidence-based guidelines for its management. Population-based cancer registries will continue to play a vital role in monitoring the burden of KS and improvements in its outcome.

Changing epidemiological patterns of HIV and AIDS in China in the post-SARS era identified by the nationwide surveillance system

Background

China has made substantial progress in tackling its HIV and AIDS epidemic. But the changing patterns of HIV and AIDS incidence based on the longitudinal observation data were rarely studied.

Methods

The reporting incidence (RI) and mortality data on HIV and AIDS in China covering 31 provinces from 2004 to 2014 were collected from the Chinese Public Health Science Data Center. To decompose the time-series data, Empirical Mode Decomposition (EMD) was applied to properly describe the trends of HIV and AIDS incidence. A mathematical model was used to estimate the relative change of incidence among provinces and age groups.

Results

A total of 483,010 newly HIV infections and 214,205 AIDS cases were reported between 2004 and 2014 nationwide. HIV infection increased from 13,258 in 2004 (RI 1.02 per 100,000 person years) to 74,048 in 2014 (RI 5.46 per 100,000). The number of AIDS cases increased from 3054 in 2004 (RI 0.23 per 100,000) to 45,145 in 2014 (RI 3.33 per 100,000). The overall relative changes for HIV infection and AIDS incidence were 1.11 (95% confidence interval [CI] 1.10–1.13) and 1.28 (95% CI 1.23–1.33), respectively. The relative increase for HIV and AIDS RI was higher in northwest provinces while lower in Henan, Xinjiang, Guangxi and Yunnan. The overall relative changes for HIV infection were 1.12 (95% CI 1.11–1.14) in males and 1.10 (95% CI 1.06–1.13) in females. For AIDS RI, the relative increases were 1.31 (95% CI 1.26–1.36) in males and 1.22 (95% CI 1.17–1.28) in females. The lowest relative increase was detected among young adults, while the largest relative increase (odds ratio [OR] > 1.30) was detected in people aged 55 years or above.

Conclusions

HIV and AIDS showed an increasing trend in China from 2004 to 2014, respectively, but the epidemic tended to be under control among provinces and young people that used to have a high HIV and AIDS incidence. Northwest China and older people could be new “hop-spots” for HIV and AIDS risk.

Clinical risk factors for in-hospital mortality in older adults with HIV infection: findings from a South African hospital administrative dataset

Introduction

The proportion of older South African adults (aged ≥50 years old) with HIV infection requiring hospitalization is likely to increase in the near future. Clinical risk factors for in-hospital mortality (IHM) in these patients are not well described. We aimed to identify clinical risk factors associated with IHM and their overall contribution towards IHM in older South African adults with HIV infection.

Methods

Clinical data for 690 older adults with HIV infection was obtained from the hospital administrative database at the Hlabisa Hospital in KwaZulu-Natal, South Africa. Logistic regression was used to determine independent clinical risk factors for IHM. Population-attributable fractions (PAFs) were calculated for all independent clinical risk factors identified.

Results

Male gender (p=0.005), CD4 count <350 cells/mm³ (p=0.035), unknown CD4 count (p=0.048), tuberculosis (p=0.033) and renal failure (p=0.013) were independently associated with IHM. Male gender contributed the most to IHM (PAF=0.22), followed by unknown CD4 count (PAF=0.14), tuberculosis (PAF=0.12), renal failure (PAF=0.06) and CD4 count <350 cells/mm³ (PAF=0.01).

Conclusion

Although further research is required to confirm our findings, there is potential for these clinical risk factors identified in our study to be used to stratify patient risk and reduce IHM in older adults with HIV infection.

Sexual Behavior of Older Adults Living with HIV in Uganda

Sexual behavior among older adults with HIV in Sub-Saharan Africa has been understudied despite the burgeoning of this population. We examined sexual behavior among older adults living with HIV in Uganda. Participants were eligible for the study if they were 50 years of age or older and living with HIV. Quantitative data were collected through face-to-face interviews, including demographic characteristics, health, sexual behavior and function, and mental health. Of respondents, 42 were men and 59 women. More than one-quarter of these HIV-positive older adults were sexually active. A greater proportion of older HIV-positive men reported being sexually active compared to women (54 vs. 15%). Among those who are sexually active, a majority never use condoms. Sixty-one percent of men regarded sex as at least somewhat important (42%), while few women shared this opinion (20%). Multivariate logistic regression analyses revealed that odds of sexual activity in the past year were significantly increased by the availability of a partner (married/cohabitating), better physical functioning, and male gender. As more adults live longer with HIV, it is critical to understand their sexual behavior and related psychosocial variables in order to improve prevention efforts.

Frequency and correlates of late presentation for HIV infection in France: older adults are a risk group - results from the ANRS-VESPA2 Study, France

Correlates of late presentation (LP) for HIV infection in Metropolitan France and French overseas departments (FODs) were assessed among HIV-infected patients recently diagnosed, using data from a large cross-sectional survey, representative of the French HIV-infected population, conducted in 2011. LP was defined as presentation with either clinical AIDS events within the calendar year of diagnosis or CD4 < 350/mm(3) and presentation with advanced disease (PAD) was defined as presentation with either clinical AIDS events or CD4 < 200/mm(3). Correlates of LP/PAD were assessed through logistic modelling, separately in Metropolitan France and FODs. In Metropolitan France, 47.7% of participants were late presenters and 29.3% presented with advanced disease. LP was more frequent among male and female migrants from sub-Saharan Africa (SSA; 58.5% and 56.4%) and non-African heterosexual males (61.8%) than among men who have sex with men (34.8%). In FODs, 53.2% of participants were late presenters and 36.8% presented with an advanced disease. LP was more frequent among men than women (60.6% vs. 45.3%) and among those with a lower level of education (56.6% vs. 47.5%). A consistent positive association was found in adjusted analyses between LP/PAD and increasing age at diagnosis among all subpopulations, in both settings. In Metropolitan France, among men who have sex with men, those self-declaring as bisexual were at higher risk of LP/PAD; among non-African heterosexual males and females, religiosity was associated with increased risk of LP/PAD; and among SSA migrants, those diagnosed within the year following their arrival in France were at higher risk of LP/PAD. Older age at diagnosis is a major risk factor for LP/PAD independently of any other socio-demographic characteristics. Promotion of HIV testing should be renewed to target each subgroup at risk while paying a particular attention to middle-aged or older adults whose attitudes and beliefs towards HIV/AIDS might prevent them from seeking testing.

HIV/AIDS epidemic among older adults in China during 2005-2012: results from trend and spatial analysis

BACKGROUND

Recent studies have indicated an increasing burden of human immunodeficiency virus (HIV)/AIDS among older adults.

METHODS

All identified people living with HIV/AIDS (PLWHA) recorded through the Chinese HIV/AIDS CRS during 2005-2012 were included in the study, except for the cases that lacked specific spatial information. Trend tests and spatial analyses were conducted.

RESULTS

Information about 73,521 PLWHA (aged ≥50 years) was collected during 2005-2012. Three provinces-Guangxi, Henan, and Yunnan-accounted for 54.4% of the identified cases during the study period. Compared with 2005, the ratio between residents and migrants among the study population decreased to 40.1% in 2012. The ratio of HIV-infected patients to AIDS patients and the ratio of males to females increased gradually among older infected adults. Results of spatial analysis indicate a clustered distribution of HIV/AIDS among older adults throughout the country. Hot spots were observed in 4 provinces (Guangxi, Henan, Yunnan, and Sichuan) and 1 municipality (Chongqing). A trend from central provinces toward southern provinces was also identified.

CONCLUSIONS

The number and proportion of HIV/AIDS among older adults have increased in recent years. The hot spots showed movement from central to southern China. A focused intervention strategy targeting the older PLWHA is urgently required in China.

Large-scale HIV testing in the older population in China: findings from a cross-sectional study

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.

Epidemiological and mortality analysis of older adults with HIV in eastern China

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.

Aging with HIV: an overview of an urban cohort in Rio de Janeiro (Brazil) across decades of life

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.

Older HIV-positive adults in Xiangxi, China: infection modes and associated risk factors

OBJECTIVE

An unusual increase in HIV/AIDS cases among rural older adults was reported between 2005 and 2008 in Xiangxi Prefecture, Hunan Province. We explored the reasons for this increase and suggested preventive measures for the future control of HIV infection in this population.

METHODS

A cross-sectional study was conducted using an HIV/AIDS registry in Hunan Province, China, to explore the likely transmission mode and risk factors of HIV/AIDS among older adults. The data were collected by face-to-face interview.

RESULTS

A total of 80 participants including 5 couples were interviewed. Among them, 46 (57.5%) participants were male and 34 (42.5%) were female. Of 46 male HIV-positive participants, 45 (97.8%) reported to have sexual intercourse with commercial sex workers. None of the female HIV-positive participants reported to have engaged in commercial sex activities. Among 46 male participants' spouses, 71.7% of them had received HIV testing and 48.5% were HIV-positive. Among 34 female participants' spouses, 92.2% of them had received HIV testing and 87.1% were HIV-positive. Ninety-seven percent of the participants reported never using condoms during sexual intercourse with their marital partners or commercial sex workers before knowing their HIV status. Eighty-two percent of participants did not know that condoms could prevent HIV/AIDS/STIs.

CONCLUSION

Chinese older adults are an underappreciated at-risk population for HIV/AIDS. The likely transmission mode of HIV/AIDS among rural older adults was unprotected sex. The HIV/AIDS/STIs knowledge among this population is very limited.

The new invincibles: HIV screening among older adults in the U.S

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.

HIV prevalence and sexual behaviour at older ages in rural Malawi

Research on HIV infection and sexual behaviour in sub-Saharan Africa typically focuses on individuals aged 15-49 years under the assumption that both become less relevant for older individuals. We test this assumption using data from rural Malawi to compare sexual behaviour and HIV infection for individuals aged 15-49 with individuals aged 50-64 and 65 and over years. Although general declines with age were observed, levels of sexual activity and HIV remained considerable: 26.7% and 73.8% of women and men aged 65+ reported having sex in the last year, respectively; men's average number of sexual partners remained above one; and HIV prevalence is significantly higher for men aged 50-64 (8.9%) than men aged 15-49 (4.1%). We conclude that older populations are relevant to studies of sexual behaviour and HIV risk. Their importance is likely to increase as access to antiretrovirals in Africa increases. We recommend inclusion of adults aged over 49 years in African HIV/AIDS research and prevention efforts.

HIV transmission and high rates of late diagnoses among adults aged 50 years and over

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.

HIV and people over 50 years old in Europe

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.

HIV-1 infected patients older than 50 years. PISCIS cohort study

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.
