HIV and viral hepatitis co-infection in New York City, 2000-2010: prevalence and case characteristics

Trends in Hepatitis C Virus and HIV Care Outcomes Among People With HIV in Georgia, United States, 2014-2019

OBJECTIVE

If untreated, hepatitis C virus (HCV) leads to poor health outcomes, including liver disease and death, particularly among people with HIV (PWH). We describe trends over time in incidence rates of HCV diagnoses among PWH in the state of Georgia.

METHODS

We constructed a retrospective cohort of PWH in Georgia by using matched HIV and HCV case surveillance data from people diagnosed with HCV infection from January 1, 2014, through December 31, 2019. We calculated annual incidence rates per 1000 person-years and estimated trends over time in HCV diagnoses among the cohort of PWH by demographic characteristics and HIV care outcomes using Poisson regression analysis, with α = .05 considered significant.

RESULTS

From 2014 through 2019, among 49 530 PWH in Georgia, 1945 (3.9%) were diagnosed with HCV infection. During this period, overall incidence per 1000 person-years of newly diagnosed HCV infection among PWH decreased from 8.7 to 4.5 (P for trend < .001). However, from 2014 through 2019, the annual incidence rates of PWH who were newly diagnosed with HCV infection increased from 4.6 to 7.1 (P for trend = .003) among people born from 1980 through 1989 and from 3.3 to 12.8 (P for trend < .001) among people born in 1990 or later.

CONCLUSION

Strategies are needed to increase prevention, diagnosis, and treatment of HIV/HCV coinfection, particularly among PWH born in 1980 and later. Routine linkage of state surveillance data can inform prioritization of PWH at highest risk of HCV infection.

Implementing a Surveillance-Based Approach to Create a Statewide Viral Clearance Cascade for Hepatitis C Among People With HIV and HCV Coinfection in Connecticut

OBJECTIVES

Highly effective direct-acting antiviral medications have made it feasible to achieve elimination of hepatis C virus (HCV), including for people with HIV and HCV coinfection. The Centers for Disease Control and Prevention offers guidance for a laboratory surveillance-based HCV viral clearance cascade, which allows public health departments to track the outcomes of people with HCV based on the following steps: ever infected, virally tested, initial infection, and cured or cleared. We examined the feasibility of this approach among people with HIV and HCV coinfection in Connecticut.

METHODS

We matched an HIV surveillance database, which included cases from the enhanced HIV/AIDS Reporting System as of December 31, 2019, and the HCV surveillance database, the Connecticut Electronic Disease Surveillance System, to define a cohort of coinfected people. We used HCV laboratory results obtained from January 1, 2016, through August 3, 2020, to determine HCV status.

RESULTS

Of 1361 people who were ever infected with HCV as of December 31, 2019, 1256 (92.3%) received HCV viral testing, 865 of 1256 people tested (68.9%) were HCV infected, and 336 of 865 infected people (38.8%) were cleared or cured. People who had undetectable HIV viral loads at most recent HIV test (<200 copies/mL) were more likely than those with detectable HIV viral loads to achieve HCV cure (P = .02).

CONCLUSIONS

A surveillance-based approach that includes data based on the Centers for Disease Control and Prevention HCV viral clearance cascade is feasible to implement, can help track population-level outcomes longitudinally, and can help identify gaps to inform HCV elimination strategies.

Improving HIV and HCV Testing in Substance Use Disorder Programs (SUDs) That Provide Medications for Opiate Use Disorder (MOUD): Role of Addressing Barriers and Implementing Universal and Site-Specific Approaches

Introduction. National strategies to end the HIV epidemic and eliminate hepatitis c (HCV) through a syndemic approach require improvements in testing for HIV and HCV. Given the intersection of the opioid crisis with HIV and HCV acquisition, substance use disorder (SUD) treatment centers providing medications for opiate use disorder (MOUD) provide a critical opportunity to expand testing. Rates of testing in MOUD clinics have been suboptimal. Method. We employed the Nominal Group Technique (NGT), Ishikawa cause and effect diagrams, and individualized Quality Improvement (QI) efforts at two SUD clinics (SUD A and B) in Connecticut (CT) as part of an HRSA-funded grant focused on improving HCV cure in persons with HIV/HCV coinfection. Baseline and longitudinal data were collected on rates of HIV and HCV testing and positivity as well as linkage to treatment. Results. Between April 1, 2019, and May 31, 2021, for SUD A and B respectively, HIV testing increased from 13% to 90% and 33% to 83%; HCV testing increased from 4% to 90% and 30% to 82%, with few reported cases of HIV/HCV coinfection. HCV testing revealed new and prior diagnoses at both sites, with subsequent referrals for treatment. Qualitative assessments identified best practices which included the institution of formal policies and procedures, streamlining of testing logistics, designation of a site champion, and broadening relevant education to staff and clients. Conclusion. Strategic assessment of barriers and facilitators to HIV and HCV testing at MOUD clinics can lead to improved testing and referral rates that are key to improving the cascade of care for both diseases.

A Review of Chronic Comorbidities in Adults Living With HIV: State of the Science

ABSTRACT

People living with HIV are living longer, high-quality lives; however, as they age, this population is at increased risk for developing chronic comorbidities, including cardiovascular disease, certain types of cancer (e.g., lung, anal, and liver), and diabetes mellitus. The purpose of this state-of-the-science review is to provide an evidence-based summary on common physical comorbidities experienced by people living and aging with HIV. We focus on those chronic conditions that are prevalent and growing and share behavioral risk factors that are common in people living with HIV. We will discuss the current evidence on the epidemiology, physiology, prevention strategies, screening, and treatment options for people living with HIV across resource settings.

Evolving trends in the prevalence of hepatitis C virus antibody positivity among HIV-infected men in a community-based primary care setting

Hepatitis C virus (HCV) infections in the United States occurred mostly among those born between 1945 and 1965. However, new infections continue to increase in recent years. To understand the changes in the prevalence and risk factors of HCV infection in different age and risk groups among men living with HIV, we performed a retrospective cross-sectional analyses of 1948 HIV-infected men at a multisite community health centre in urban/suburban and rural Maryland from 2003 through 2014. We used multivariate logistic regression to determine factors associated with HCV antibody (anti-HCV) positivity and restricted cubic spline method to model trends in anti-HCV prevalence over time. The overall anti-HCV prevalence was 24.2%. The annual prevalence declined in the full cohort, from 38% in 2003 to 24% in 2014, and among those ≥ 40 years old. However, the annual prevalence increased initially and then stabilized in the groups of men who were younger (<40 years old) or had injection-drug use and/or sex with men. Among the younger injection-drug users, the prevalence rose from 33% in 2003 to 79% in 2009 and then stabilized. The independent predictors for anti-HCV positivity differed between the men with and without injection-drug use and between those < 40 and ≥ 40 years old. Notably, a high prevalence of anti-HCV was observed among the younger, white injection-drug users residing in rural areas. Thus, the HCV epidemic continued unabated among high-risk individuals in this diverse population of HIV-infected men. The ongoing HCV transmission among young HIV-infected men poses a challenge en route to HCV eradication.

Sustained attention and vigilance deficits associated with HIV and a history of methamphetamine dependence

BACKGROUND

Human immunodeficiency virus (HIV)-associated neurocognitive disorders persist in the era of antiretroviral therapy. One factor that is elevated among persons with HIV (PWH) and independently associated with neurocognitive impairment is methamphetamine dependence (METH). Such dependence may further increase cognitive impairment among PWH, by delaying HIV diagnosis (and thus, antiretroviral therapy initiation), which has been posited to account for persistent cognitive impairment among PWH, despite subsequent treatment-related viral load suppression (VLS; <50 copies of the virus per milliliter in plasma or cerebrospinal fluid). This study examined the main and interactive (additive versus synergistic) effects of HIV and history of METH on the sustained attention and vigilance cognitive domain, while controlling for VLS.

METHODS

Participants included 205 (median age = 44 years; 77% males; HIV-/METH- n = 67; HIV+/METH - n = 49; HIV-/METH+ n = 36; HIV+/METH+ n = 53) individuals enrolled in the Translational Methamphetamine AIDS Research Center, who completed Conners' and the 5-Choice continuous performance tests (CPTs).

RESULTS

METH participants exhibited deficits in sustained attention and vigilance; however, these effects were not significant after excluding participants who had a positive urine toxicology screen for methamphetamine. Controlling for VLS, PWH did not have worse sustained attention and vigilance, but consistently displayed slower reaction times across blocks, relative to HIV- participants. There was no HIV x METH interaction on sustained attention and vigilance.

CONCLUSIONS

Recent methamphetamine use among METH people and detectable viral loads are detrimental to sustained attention and vigilance. These findings highlight the need for prompt diagnosis of HIV and initiation of antiretroviral therapy, and METH use interventions.

Proportion and Characterization of Co-infections of HIV and Hepatitis C or Hepatitis B among People with HIV in Alabama, 2007-2016

OBJECTIVES

People living with human immunodeficiency virus (HIV) have an increased risk of other infections, including viral hepatitis, which can complicate the treatment and progression of the disease. We sought to characterize Alabama cases of HIV co-infected with hepatitis C virus or hepatitis B virus.

METHODS

Using surveillance data, we defined co-infection as a person identified as having hepatitis C or hepatitis B and HIV during 2007-2016. We compared demographics, outcomes, and risk factors for co-infected versus monoinfected individuals with HIV. We mapped co-infected individuals' distribution.

RESULTS

Of 5824 people with HIV, 259 (4.4%) were co-infected with hepatitis C (antibody or RNA positive) and 145 (2.5%) with hepatitis B (surface antigen, e antigen, or DNA positive) during 2007-2016. Individuals with HIV and hepatitis C had a greater odds of injection drug use (adjusted odds ratio 9.7; 95% confidence interval 6.0-15.5). Individuals with HIV and hepatitis B had a greater odds of male-to-male sexual contact (adjusted odds ratio 1.7; 95% confidence interval 1.1-2.6). Co-infection was greater in urban public health districts.

CONCLUSIONS

We identified risk behaviors among Alabama populations associated with increased odds for HIV and viral hepatitis co-infection. Outreach, prevention, testing, and treatment resources can be targeted to these populations.

Hepatitis C Coinfection and Mortality in People Living with HIV in Middle Tennessee

HIV and hepatitis C virus (HCV) coinfection is associated with poor health outcomes. This study was designed to assess risk factors for and mortality with coinfection before direct-acting antiviral treatment availability in a state with an evolving opioid epidemic. HCV infection was determined from review of the medical record at two clinics serving the majority of people living with HIV (PLWH) in care in Middle Tennessee from 2004 to 2013. Association of potential risk factors with HCV-positivity was assessed using logistic regression. Association of HCV-positivity with mortality was assessed with a Cox proportional hazards model, adjusting for selected covariates. A total of 3,501 patients were included: 24% female; 51% men who have sex with men; 47% white; 44% African American/black; median age of 38 at their first visit; median most recent CD4 count 502 cells/μL (301-716); and HIV viral load 47 copies/mL (39-605); followed for a median of 3.0 (1-5) years. Prevalence of HCV was 13%. Those with a history of injection drug use (IDU) demonstrated the highest odds of HCV-positivity [odds ratio 12.94; 95% confidence interval (CI) 9.39-17.83]. There were 305 deaths; median age at death was 47 years (40-53). HCV coinfection was associated with greater mortality (hazard ratio 1.61; 95% CI 1.20-2.17; p < .001). Among PLWH, HCV coinfection was associated with IDU and an independent predictor of mortality. These results affirm the importance of HCV coinfection and inform interventions targeting the continuum of HCV care, uptake of HCV treatment, and the impact of drug use in this population.

Implementing a Comprehensive HCV Clinic within an HIV Clinic: A Model of Care for HCV Micro-elimination

BACKGROUND

Among the 1.2 M persons living with HIV in the United States, 25% are co- infected with HCV. The availability of effective direct antiviral agents (DAAs) makes the goal of HCV elimination feasible, but implementation requires improvements to the HCV treatment cascade, especially linkage to and initiation of treatment in underserved populations.

METHODS

In this retrospective review, a cohort of patients receiving care at a hospital-based HIV clinic in New Haven, CT (1/1/2014-3/31/2017) with chronic HCV infection not previously treated with DAAs were followed longitudinally. Patients were referred to a co-located multi-disciplinary team. Standardized referral and treatment algorithms, electronic medical record templates were developed; monthly meetings were held; a registry was created to review progress.

RESULTS

Of 173 patients, 140 (80.9%) were 50-70 years old; 115 (66.5%) male; 99 (57.2%) African-American, 43 (24.9%) White, 23 (13.3%) Hispanic. Comorbidities included: cirrhosis (25.4%); kidney disease (17.3%) mental health issues (60.7%); alcohol abuse (30.6%); active drug use (54.3%). Overall, 161 (93.1%) were referred, 147 (85%) linked, 122 (70.5%) prescribed DAAs, 97 (56.1%) had SVR12. Comparison between those with SVR12 and those unsuccessfully referred, linked or treated, showed that among those not-engaged in HCV care, there was a higher proportion of younger (mean age 54.2 vs 57 years old, p=0.022), female patients (p= 0.001) and a higher frequency of missed appointments.

CONCLUSIONS

Establishing a co-located HCV clinic within an HIV clinic resulted in treatment initiation in 70.5% and SVR12 in 56.1%. This success in a hard-to-treat population is a model for achieving WHO micro-elimination goals.

Comparison of Demographic, Epidemiological, Immunological, and Clinical Characteristics of Patients with HIV Mono-infection Versus Patients Co-infected with HCV or/and HBV: A Serbian Cohort Study

OBJECTIVE

The study aimed to correlate the status of hepatitis C (HCV) and hepatitis B virus (HBV) co-infection in patients with human immunodeficiency virus (HIV) infection with clinical and demographic data prior to starting highly active antiretroviral therapy (HAART) and assess the impact of HCV and HBV co-infection on the natural history of HIV infection.

PATIENTS AND METHODS

The study involved a total of 836 treatment-naive patients with available serological status for HBV and HCV at the point of therapy initiation. Patients were stratified into four groups: HIV mono-infection, HIV/HCV, HIV/HBV, and HIV/HCV/HBV co-infection. Demographic, epidemiological, immunological and clinical characteristics were analyzed in order to assess the possible impact of HCV and HBV co-infection on HIV - related immunodeficiency and progression to AIDS.

RESULTS

The prevalence of HCV and HBV co-infection in our cohort was 25.7% and 6.3%, respectively. Triple HIV/HCV/HBV infection was recorded in 1.7% of the patients. In comparison with those co-infected with HCV, patients with HIV mono-infection had lower levels of serum liver enzymes activity and higher CD4 cell counts, and were less likely to have CD4 cell counts below100 cells/µL and clinical AIDS, with OR 0.556 and 0.561, respectively. No difference in the development of advanced immunodeficiency and/or AIDS was recorded between patients with HIV monoinfection and those co-infected with HBV, or both HCV/HBV.

CONCLUSION

HIV/HCV co-infection was found to be more prevalent than HIV/HBV co-infection in a Serbian cohort. Co-infection with HCV was related to more profound immunodeficiency prior to therapy initiation, reflecting a possible unfavorable impact of HCV on the natural history of HIV infection.

Characteristics of HBV infection in 705 HIV-infected patients under lamivudine-based antiretroviral treatment from three regions in China

Purpose

This study aimed to investigate the HIV and hepatitis B virus (HBV) co-infection in three HIV high endemic areas with different modes of HIV transmission and explore the HBV nucleos(t)ide analogue resistance (NUCr) substitutions in this cohort receiving antiretroviral therapy (ART).

Patients and methods

The enrolled 705 HIV-infected patients were from three different regions in China and received lamivudine-based ART for at least 1 year. After screening for hepatitis B surface antigen (HBsAg), the hepatitis B e antigen (HBeAg), and antibody against hepatitis B core antigen (anti-HBc and anti-HBc IgM), HBV DNA in plasma of patients positive for HBsAg was tested. The reverse transcriptase (RT) sequences of HBV were analyzed by direct sequencing.

Results

The overall HBsAg-positive rate was 7.1% (50/705) (Guangxi [25/170, 14.7%], Xinjiang [13/257, 5.1%], and Henan [12/278, 4.3%]). The age, transmission route, and ethnic status were found to be associated with HIV/HBV co-infection. We obtained 23 HBV RT sequences belonging to genotypes B (9/23, 39.1%), C (13/23, 56.5%), and D (1/23, 4.4%). About 65.2% (15/23) of RT sequences harbored NUCr substitutions, all of which had combination substitution patterns. Patients with HBV NUCr had significantly higher HBV DNA level and ratio of HBeAg-positive than those without NUCr. None of the patients was found to have both lamivudine-resistant HBV and HIV.

Conclusion

Our results suggested that HBsAg-positive rate in the studied patients was similar to that of the general population in each of the studied regions, where the age, transmission route, and ethnic status might also play roles in HIV/HBV co-infection. The HBV combination NUCr substitutions were common in co-infected patients under ART. Monitoring of HBV infection and NUCr substitutions in HIV-infected patients would help in providing better clinical decisions and management, thus lowering patients’ risks to develop end-stage liver diseases.

Syndemic Characterization of HCV, HBV, and HIV Co-infections in a Large Population Based Cohort Study

BACKGROUND

Limited data are available on HBV, HCV, and HIV co-infections and triple infection. We characterized co-occurrence of HIV, HBV, and HCV infections at the population level in British Columbia (BC) to identify patterns of predisposing factors unique to co-infection subgroups.

METHODS

We analyzed data from the BC Hepatitis Testers Cohort, which includes all individuals tested for HCV or HIV in BC between 1992 and 2013, or included in provincial public health registries of HIV, HCV, HBV, and active tuberculosis. Individuals were classified as negative, mono-, and co-infection groups based on HIV, HBV, and HCV status. We evaluated associations between risk factors (injection drug use, sexual orientation etc.) and co-infection groups using multivariate multinomial logistic regression.

FINDINGS

Of a total of 1,376,989 individuals included in the analysis, 1,276,290 were negative and 100,699 were positive for HIV, HBV, and/or HCV. Most cases (91,399, 90.8%) were mono-infected, while 3991 (4.0%) had HBV/HCV, 670 HBV/HIV (0.7%), 3459 HCV/HIV (3.4%), and 1180 HBV/HCV/HIV (1.2%) co-infection. Risk factor and demographic distribution varied across co-infection categories. MSM classification was associated with higher odds of all HIV co-infection groups, particularly HBV/HIV (OR 6.8; 95% CI: 5.6, 8.27), while injection drug use was most strongly associated with triple infection (OR 64.19; 95% CI: 55.11, 74.77) and HIV/HCV (OR 23.23; 95% CI: 21.32, 25.31).

INTERPRETATION

Syndemics of substance use, sexual practices, mental illness, socioeconomic marginalization, and co-infections differ among population groups, highlighting avenues for optimal composition and context for health services to meet each population's unique needs.

Effect of Hepatocellular Carcinoma on Mortality Among Individuals With Hepatitis B or Hepatitis C Infection in New York City, 2001-2012

Background

Hepatocellular carcinoma (HCC) is a complication of chronic hepatitis B and C virus (HBV and HCV) infection. New York City (NYC) has a high prevalence of HBV and HCV, and infected persons likely face increased mortality from HCC and other causes. We describe the mortality profile of NYC residents with HBV or HCV, emphasizing the contributions of HCC and HIV coinfection.

Methods

 Two existing data sets were combined to examine all individuals diagnosed with HBV or HCV in NYC first reported to the Health Department during 2001-2012 and their HCC, HIV, and vital status. Logistic regression was used to calculate the odds of HCC diagnosis by viral hepatitis status, whereas Cox proportional hazard regression was used to estimate the hazard of death by HCC/HIV status.

Results

In total, 120 952 and 127 933 individuals were diagnosed with HBV or HCV, respectively. HCV-infected individuals had 17% higher odds of HCC diagnosis than HBV-infected individuals and 3.2 times higher odds of HIV coinfection. Those with HCV were twice as likely to die during the study period (adjusted hazard ratio, 2.04; 95% confidence interval, 1.96-2.12). The risk of death increased for those with HIV or HCC and was highest for those with both conditions.

Conclusions

HCC and HIV represent substantial risks to survival for both HBV- and HCV-infected individuals. Individuals with HBV need close monitoring and treatment, when indicated, and routine HCC screening. Those with HCV need increased, timely access to curative medications before developing liver disease.

HIV and viral hepatitis coinfection analysis using surveillance data from 15 US states and two cities

Coinfection with human immunodeficiency virus (HIV) and viral hepatitis is associated with high morbidity and mortality in the absence of clinical management, making identification of these cases crucial. We examined characteristics of HIV and viral hepatitis coinfections by using surveillance data from 15 US states and two cities. Each jurisdiction used an automated deterministic matching method to link surveillance data for persons with reported acute and chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infections, to persons reported with HIV infection. Of the 504 398 persons living with diagnosed HIV infection at the end of 2014, 2.0% were coinfected with HBV and 6.7% were coinfected with HCV. Of the 269 884 persons ever reported with HBV, 5.2% were reported with HIV. Of the 1 093 050 persons ever reported with HCV, 4.3% were reported with HIV. A greater proportion of persons coinfected with HIV and HBV were males and blacks/African Americans, compared with those with HIV monoinfection. Persons who inject drugs represented a greater proportion of those coinfected with HIV and HCV, compared with those with HIV monoinfection. Matching HIV and viral hepatitis surveillance data highlights epidemiological characteristics of persons coinfected and can be used to routinely monitor health status and guide state and national public health interventions.

HBV, HCV, and HBV/HCV co-infection among HIV-positive patients in Hunan province, China: Regimen selection, hepatotoxicity, and antiretroviral therapy outcome

Co-infection with hepatitis B (HBV) and C (HCV) is common among people living with HIV (PLHIV). This study investigates the impacts of hepatitis co-infection on antiretroviral therapy (ART) outcomes and hepatotoxicity in PLHIV. The cohort study included 1984 PLHIV. Hepatotoxicity was defined by elevated alanine aminotransferase (ALT) levels. ART outcomes were measured by CD4 cell counts, viral load, and mortality rate in patients. Among 1984 PLHIV, 184 (9.3%) were co-infected with HBV and 198 (10.0%) with HCV and 54 (2.7%) were co-infected with HBV and HCV. Of these patients, 156 (7.9%) had ALT elevation ≥ grade 1 at baseline. During the course of ART, the mortality rate and its adjusted hazard ratio (AHR) in PLHIV who were co-infected with HCV (2.6/100 person-years [py], AHR = 2.3, 95%CI 1.1-4.7) was higher than for patients with mono-infected HIV, as it was for those with an elevated ALT (4.4/100 py, AHR = 3.8, [1.7-8.2]) at baseline compared to those with normal ALT. After 6-12 months of ART, the incidence of hepatotoxicity among all the patients was 3.7/100 py. The risk of hepatotoxicity was higher in HCV co-infected (18.6/100 py, adjusted odds ratio [AOR] = 12.4, [8.1-18.2]) than HIV mono-infected patients, and for all regimens (nevirapine: 30.0/100 py, 34.2, 7.3-47.9; zidovudine/stavudine: 24.7/100 py, 22.1, 7.1-25.5; efavirenz: 14.5/100 py, 9.4, 3.5-19.2; lopinavir/ritonavir: 40.1/100 py, 52.2, 9.5-88.2) except tenofovir (4.3/100 py, 4.9, 0.8-9.5). Patients with HBV/HCV co-infected had high hepatotoxicity (10.0/100 py, 6.3, 1.2-23.3) over the same period. Patients with HCV co-infection and HBV/HCV co-infection demonstrated higher hepatotoxicity rate compared with HIV mono-infected patients in China.

HIV-hepatitis B virus coinfection: epidemiology, pathogenesis, and treatment

: HIV infection has a significant impact on the natural history of chronic hepatitis B virus (HBV) infection, with increased levels of HBV DNA, accelerated progression of liver disease and increased liver-associated mortality compared with HBV monoinfection. Widespread uptake and early initiation of HBV-active antiretroviral therapy has substantially improved the natural history of HIV-HBV coinfection but the prevalence of liver disease remains elevated in this population. In this paper, we review recent studies examining the natural history and pathogenesis of liver disease and seroconversion in HIV-HBV coinfection in the era of HBV-active antiretroviral therapy and the effects of HIV directly on liver disease. We also review novel therapeutics for the management of HBV with a particular emphasis on clinical strategies being developed for an HBV cure and an HIV cure and their impact on HIV-HBV coinfected individuals.

Impact of hepatitis B on mortality and specific causes of death in adults with and without HIV co-infection in NYC, 2000-2011

High rates of immigration from endemic countries contribute to the high chronic hepatitis B (HBV) prevalence in New York City (NYC) compared to the United States overall, i.e. about 1 million individuals. We describe the impact of HBV infection on mortality and specific causes of death in NYC. We matched surveillance and vital statistics mortality data collected from 2000 to 2011 by the New York City Department of Health and Mental Hygiene (DOHMH) and analysed demographics and premature deaths (i.e. whether death occurred at <65 years) in persons with and without chronic HBV or HIV infection (excluding those with hepatitis C). From 2000 to 2011, a total of 588 346 adults died in NYC. Of all decedents, 568 753 (97%) had no report of HIV or HBV, and 4346 (0·7%) had an HBV report. Of HBV-infected decedents, 1074 (25%) were HIV co-infected. Fifty-five percent of HBV mono-infected and 95% of HBV/HIV co-infected decedents died prematurely. HBV disproportionately impacts two subgroups: Chinese immigrants and HIV-infected individuals. These two subgroups are geographically clustered in different neighbourhoods of NYC. Tailoring prevention and treatment messages to each group is necessary to reduce the overall burden of HBV in NYC.

Population-Based Estimates of Life Expectancy After HIV Diagnosis: United States 2008-2011

INTRODUCTION

Using National HIV surveillance system data, we estimated life expectancy and average years of life lost (AYLL) among persons diagnosed with HIV infection during 2008-2011.

METHODS

Population-based surveillance data, restricted to persons with diagnosed HIV infection aged 13 years or older, from all 50 states and Washington, D.C. were used to estimate life expectancy after HIV diagnosis using the life table method. Generated estimates were compared with life expectancy in the general population in the same calendar year to calculate AYLL. Life expectancy and AYLL were also estimated for subgroups by age, sex, and race/ethnicity.

RESULTS

The overall life expectancy after HIV diagnosis in the United States increased by 3.43 years from 25.43 (95% CI: 25.37 to 25.49) in 2008 to 28.86 (95% CI: 28.80 to 28.92) in 2011. Improvements were observed irrespective of sex, race/ethnicity, transmission category, and stage of disease at diagnosis, though the extent of improvement varied by different characteristics. Based on the life expectancy in the general population, in 2010, the AYLL were 12.8 years for males and 16.5 years for females. By race/ethnicity, on average, blacks (13.3 years) and whites (13.4 years) had fewer AYLL than Hispanics/Latinos (14.7).

CONCLUSIONS

Despite improvements in life expectancy among people diagnosed with an HIV infection during 2008-2011, disparities by sex and by race/ethnicity persist. Targeted efforts should continue to further reduce disparities and improve life expectancy after HIV diagnosis.
