The Era of DAAs: Assessing the Patients' Characteristics, Clinical Impact, and Emergence of Comorbidities in HIV/HCV-Coinfected versus HIV-Infected Individuals.

Objective: To determine whether HIV-infected individuals versus individuals with HIV/HCV coinfection, in the era of interferon-free therapies, exhibit an increased incidence of comorbidities and non-AIDS-related events. Methods: A retrospective analysis was conducted by collecting data from clinical records of Spanish patients at a tertiary hospital involving HIV/HCV-coinfected and HIV-infected patients, all with effectively controlled HIV. Coinfected patients underwent HCV clearance using direct-acting antivirals (DAAs) and had no history of interferon treatment. The incidences of hypertension, diabetes mellitus, cardiovascular disease, kidney disease, liver disease, non-AIDS cancer, and death were compared between the groups. Multivariate adjustments for all factors potentially impacting outcomes were used to assess the risk of clinical event onset. Propensity score (PS) analyses were also conducted to support the multivariate model results. Results: Data were available from 229 HIV/HCV-coinfected patients and 229 HIV-infected patients. Both cohorts were comparable in terms of age, gender distribution, follow-up, and HIV-related characteristics. Multivariate models and PS showed that previous exposure to HCV was not associated with the onset of any clinical events studied. Significant differences between HIV/HCV-coinfected and HIV-infected were not found for survival according to the log-rank test (p = 0.402). Conclusions: Successful HCV elimination using DAAs improved the outlook regarding comorbidities and survival across HIV/HCV-coinfected cohorts. Early HCV detection and DAA therapy could enhance clinical results. These findings provide an optimistic perspective for those living with HIV/HCV coinfection and underscore the importance of continuing efforts toward early detection and DAA treatment initiation.

Evolving AIDS- and non-AIDS Mortality and Predictors in the PISCIS Cohort of People Living With HIV in Catalonia and the Balearic Islands (Spain), 1998-2020.

Effective antiretroviral therapy (ART) has substantially reduced acquired immunodeficiency syndrome (AIDS)-related deaths, shifting the focus to non-AIDS conditions in people living with human immunodeficiency virus (HIV) (PLWH). We examined mortality trends and predictors of AIDS- and non-AIDS mortality in the Population HIV Cohort from Catalonia and Balearic Islands (PISCIS) cohort of PLWH from 1998 to 2020. We used a modified Coding Causes of Death in HIV protocol, which has been widely adopted by various HIV cohorts to classify mortality causes. We applied standardized mortality rates (SMR) to compare with the general population and used competing risks models to determine AIDS-related and non-AIDS-related mortality predictors. Among 30 394 PLWH (81.5% male, median age at death 47.3), crude mortality was 14.2 per 1000 person-years. All-cause standardized mortality rates dropped from 9.6 (95% confidence interval [CI], 8.45-10.90) in 1998 through 2003 to 3.33 (95% CI, 3.14-3.53) in 2015 through 2020, P for trend = .0001. Major causes were AIDS, non-AIDS cancers, cardiovascular disease, AIDS-defining cancers, viral hepatitis, and nonhepatitis liver disease. Predictors for AIDS-related mortality included being aged ≥40 years, not being a man who have sex with men, history of AIDS-defining illnesses, CD4 < 200 cells/µL, ≥2 comorbidities, and nonreceipt of ART. Non-AIDS mortality increased with age, injection drug use, heterosexual men, socioeconomic deprivation, CD4 200 to 349 cells/µL, nonreceipt of ART, and comorbidities, but migrants had lower risk (adjusted hazard risk, 0.69 [95% CI, .57-.83]). Mortality rates among PLWH have significantly decreased over the past 2 decades, with a notable shift toward non-AIDS-related causes. Continuous monitoring and effective management of these non-AIDS conditions are essential to enhance overall health outcomes.

Low incidence of advanced neurological burden but high incidence of age-related conditions that are dementia risk factors in aging people living with HIV: a data-linkage 10-year follow-up study

Although increasing research is focusing on age-related comorbidities (ARC) among people living with HIV (PLHIV), no studies have concomitantly assessed non-HIV age-related neurological disorders (e.g., Alzheimer’s dementia). A total of 254 PLHIV and 69 HIV-negative controls completed baseline medical history and cognitive testing. ARC data were collected from medical records over the subsequent 9-10 years and included all types of strokes, all types of dementia, mild cognitive impairment, Parkinson's disease, motor neuron disease (grouped into a non-HIV age-related neurological category), cardiovascular disease, chronic kidney disease, chronic liver disease, chronic lung disease, non-AIDS cancers, osteoporosis, and diabetes. Kaplan–Meier curves assessed differences in the incident rates (per 1000 person year) of groups of ARC as defined above and combined ARC (i.e., development of any of the ARC) among younger (baseline age < 50) and older (baseline age ≥ 50) PLHIV and younger and older controls. Cox-proportional hazard models assessed the individual and interaction effects of HIV status and chronological age, in addition to a range of demographic and clinical variables including historical and baseline HIV brain involvement on the risk of developing combined ARC. Older PLHIV had a higher incidence of cardiovascular disease, osteoporosis, and combined ARC compared to other groups (p < 0.05). Incident rate of non-HIV age-related neurological disorders was 2.3 [0.93, 4.79] per 1000 person year. While this incident rate was higher in older PLHIV (5.37 [1.97, 11.92]) than older HIV-negative participants (3.58 [0.18-17.67]), this was not significant. In multivariate analyses, HIV status and chronological age, but not their interaction, and smoking were associated with higher risk of combined ARC (p < 0.05). In analyses focusing on PLHIV, older age and taking abacavir/efavirenz/atazanavir/darunavir containing antiretroviral treatments at the time of diagnosis were associated with greater ARC (p < 0.05). Non-HIV age-related neurological disorders are uncommon in older PLHIV, where the majority were < 70 years of age at the end of follow-up. However, the greater burden of ARC among older PLHIV, most of which are established dementia risk factors, warrants the establishment of commensurate prevention strategies and greater attention to neurocognitive screening.

Ritonavir-boosted antiretroviral therapy with paclitaxel: will it lead to boosted toxicity?

Ritonavir-boosted antiretroviral therapy with paclitaxel: will it lead to boosted toxicity?

Aging, trends in CD4+/CD8+ cell ratio, and clinical outcomes with persistent HIV suppression in a dynamic cohort of ambulatory HIV patients.

Age blunts CD4+ lymphocyte cell count/μl (CD4+) improvements observed with antiretroviral therapy (ART)-induced viral suppression among people with HIV (PWH). Prolonged viral suppression reduces immune dysregulation, reflected by rising CD4+/CD8+ ratios (CD4+/CD8+). We studied CD4+/CD8+ over time to determine whether it predicts risk for select comorbidities and mortality among aging PWH with viral suppression. We studied HIV Outpatient Study (HOPS) participants prescribed ART during 2000-2018 who achieved a viral load less than 200 copies/ml on or after 1 January 2000, and remained virally suppressed at least 1 year thereafter. We modeled associations of CD4+/CD8+ with select incident comorbidities and all-cause mortality using Cox regression and controlling for demographic and clinical factors. Of 2480 eligible participants,1145 (46%) were aged less than 40 years, 835 (34%) 40-49 years, and 500 (20%) ≥ 50 years. At baseline, median CD4+/CD8+ was 0.53 (interquartile range: 0.30-0.84) and similar among all age groups (P = 0.18). CD4+/CD8+ values and percentage of participants with CD4+/CD8+ at least 0.70 increased within each age group (P < 0.001 for all). CD4+/CD8+ increase was greatest for PWH aged less than 40 years at baseline. In adjusted models, most recent CD4+/CD8+less than 1.00 and less than 0.70 were independently associated with higher risk of non-AIDS cancer and mortality, respectively. Pretreatment immune dysregulation may persist as indicated by CD4+/CD8+ less than 0.70. Persistent viral suppression can improve immune dysregulation over time, reducing comorbidity, and mortality risk. Monitoring CD4+/CD8+ among ART-treated PWH with lower values provide a means to assess for mortality and comorbidity risk.

Abstract PO-024: Survivorship care plan for cancer prevention and screening for people living with HIV (PLWH)

Abstract BACKGROUND. Over 1.2 million people living with HIV (PLWH) in the US are aging, many with the chance for normal or near-nomal life expectancy. Yet PLWH are at significantly increased risk for non-AIDS associated cancers due to immunocompromise, antiretroviral medications, lifestyle factors, and social determinants of health issues. HIV disproportionately affects Blacks, those from lower socioeconomic status, the uninsured, and the Southern US. Outcomes from PLWH diagnosed wtih cancer are consistently worse compared to those who are HIV negative, even when diagnosed at the same stage. However, PLWH are often unaware of their higher risk status and are infrequently referred for cancer prevention or screening by providers, despite these disparities in screening and outcomes. METHODS: To explore reasons why PLWH did not engage in cancer prevention or screening activities, we partnered with urban and rural community clinics with a mixed methods study design, including a quantitative survey and focus groups. RESULTS: In our sample (N=178), 90.4% Black, 57% female, significant differences were found between rural and urban settings related to guideline-concordant uptake of cancer screening and prevention. Only 37% subjects overall reported participating in regular cancer screening. Among women over 50 years who met criteria for breast cancer screening, 100% of women in the rural setting were screened while 55% of eligible women in the urban community received breast cancer screening (p=0.009). Participants from both settings demonstrated gaps in knowledge of their own cancer risk or need to pursue screening. Urban participants were more likely than rural to strongly disagree wtih the statement that HIV+ individuals are at higher risk for cancer (p&amp;lt;0.001). Qualitative data indicated the main reason why PLWH did not participate in prevention or screening activities was because participants were seldom referred for screening by their HIV clinic provider or informed of their risk status. Other qualitative data themes were shock and surprise at learning of their increased risk, or how certain behaviors might reduce cancer risk. DISCUSSION: Upon reviewing results with community partners, the suggestion was made that an HIV Survivorship Care Plan, similar to a Cancer Survivor Care Plan, be developed that could be part of the medical record. The HIV Survivorship Care Plan would incorporate cancer and other chronic disease screening, prevention interventions, and surveillance that would be important for aging PLWH to ensure both patients and providers adhered to evidence-based practices. CONCLUSIONS: PLWH are at increased risk for cancer incidence and mortality as they age, yet are often overlooked as a high-risk population that could greatly benefit from prevention and screening.The application of an HIV Survivorship Care Plan intervention is a novel approach to reduce disparities and improve quality of care and outcomes for PLWH. The tool will be tested and evaluated through additional community-engaged partnerships targeting PLWH. Citation Format: Theresa W. Gillespie, Loree Mincey, Yuan Liu, Denise Ballard, Kimberly W.

Trends in hospitalizations and deaths in HIV-infected patients in Spain over two decades.

The prognosis of HIV infection dramatically improved after the introduction of triple antiretroviral therapy 25 years ago. Herein, we report the impact of further improvements in HIV management since then, looking at all hospitalizations in persons with HIV (PWH) in Spain. A retrospective study using the Spanish National Registry of Hospital Discharges. Information was retrieved since 1997-2018. From 79 647 783 nationwide hospital admissions recorded during the study period, 532 668 (0.67%) included HIV as diagnosis. The mean age of PWH hospitalized increased from 33 to 51 years (P < 0.001). The rate of HIV hospitalizations significantly declined after 2008. Comparing hospitalizations during the first (1997-2007) and last (2008-2018) decades, the rate of non-AIDS illnesses increased, mostly due to liver disease (from 35.9 to 38.3%), cardiovascular diseases (from 12.4 to 28.2%), non-AIDS cancers (from 6.4 to 15.5%), and kidney insufficiency (from 5.4 to 13%). In-hospital deaths occurred in 5.5% of PWH, declining significantly over time. Although most deaths were the result from AIDS conditions (34.8%), the most frequent non-AIDS deaths were liver disease (47.1%), cardiovascular events (29.2%), non-AIDS cancers (24.2%), and kidney insufficiency (20.7%). Hospital admissions in PWH significantly declined after 2008, following improvements in HIV management and antiretroviral therapy. Non-AIDS cancers, cardiovascular events and liver disease represent a growing proportion of hospital admissions and deaths in PWH.

Incident bone fracture and mortality in a large HIV cohort outpatient study, 2000-2017, USA.

Low bone mineral density (BMD) and fracture are more common among persons with HIV (PWH) than those without HIV infection. We evaluated the association of bone fracture with mortality among PWH, controlling for sociodemographic, behavioral, and clinical factors. We analyzed data from HIV Outpatient Study (HOPS) participants seen at nine US HIV clinics during January 1, 2000, through September 30, 2017. Incident fracture rates and post-fracture mortality were compared across four calendar periods. Cox proportional hazards analyses determined factors associated with all-cause mortality among all participants and those with incident fracture. Among 6763 HOPS participants, 504 (7.5%) had incident fracture (median age = 47 years) and 719 (10.6%) died. Of fractures, 135 (26.8%) were major osteoporotic (hip/pelvis, wrist, spine, arm/shoulder). During observation, 27 participants with major osteoporotic fractures died (crude mortality 2.97/100 person-years [PY]), and 48 with other site fractures died (crude mortality 2.51/100 PY). Post-fracture, age- and sex-adjusted all-cause mortality rates per 100 PY decreased from 8.5 during 2000-2004 to 1.9 during 2013-2017 (P<0.001 for trend). In multivariable analysis, incident fracture was significantly associated with all-cause mortality (Hazard Ratio 1.48, 95% confidence interval 1.15-1.91). Among 504 participants followed post-fracture, pulmonary, kidney, and cardiovascular disease, hepatitis C virus co-infection, and non-AIDS cancer, remained independently associated with all-cause mortality. Incident fracture was associated with 48% greater risk of all-cause mortality among US PWH in care, underscoring the need for BMD screening and fracture prevention. Although fracture rates among PWH increased during follow-up, post-fracture death rates decreased, likely reflecting advances in HIV care.

Clinical Outcomes of 2-Drug Regimens vs 3-Drug Regimens in Antiretroviral Treatment-Experienced People Living With Human Immunodeficiency Virus.

Limited data exist that compare clinical outcomes of 2-drug regimens (2DRs) and 3-drug regimens (3DRs) in people living with human immunodeficiency virus. Antiretroviral treatment-experienced individuals in the International Cohort Consortium of Infectious Diseases (RESPOND) who switched to a new 2DR or 3DR from 1 January 2012-1 October 2018 were included. The incidence of clinical events (AIDS, non-AIDS cancer, cardiovascular disease, end-stage liver and renal disease, death) was compared between regimens using Poisson regression. Of 9791 individuals included, 1088 (11.1%) started 2DRs and 8703 (88.9%) started 3DRs. The most common 2DRs were dolutegravir plus lamivudine (22.8%) and raltegravir plus boosted darunavir (19.8%); the most common 3DR was dolutegravir plus 2 nucleoside reverse transcriptase inhibitors (46.9%). Individuals on 2DRs were older (median, 52.6 years [interquartile range, 46.7-59.0] vs 47.7 [39.7-54.3]), and a higher proportion had ≥1 comorbidity (81.6% vs 73.9%). There were 619 events during 27 159 person-years of follow-up (PYFU): 540 (incidence rate [IR] 22.5/1000 PYFU; 95% confidence interval [CI]: 20.7-24.5) on 3DRs and 79 (30.9/1000 PYFU; 95% CI: 24.8-38.5) on 2DRs. The most common events were death (7.5/1000 PYFU; 95% CI: 6.5-8.6) and non-AIDS cancer (5.8/1000 PYFU; 95% CI: 4.9-6.8). After adjustment for baseline demographic and clinical characteristics, there was a similar incidence of events on both regimen types (2DRs vs 3DRs IR ratio, 0.92; 95% CI: .72-1.19; P = .53). This is the first large, international cohort to assess clinical outcomes on 2DRs. After accounting for baseline characteristics, there was a similar incidence of events on 2DRs and 3DRs. 2DRs appear to be a viable treatment option with regard to clinical outcomes. Further research on resistance barriers and long-term durability of 2DRs is needed.

Trends and causes of mortality in a population-based cohort of HIV-infected adults in Spain: comparison with the general population

Combination antiretroviral therapy reduces mortality of HIV-infected persons. In Spain, where this therapy is widely available, we aim to evaluate mortality trends and causes of death in HIV-infected adults, and to estimate the excess mortality compared to the general population. From 1999 to 2018 mortality by causes was analyzed in a population-based cohort of adults aged 25 to 74 years diagnosed with HIV infection in Spain. Observed deaths and expected deaths according mortality in the general population of the same sex and age were compared using standardized mortality ratios (SMRs). HIV-infected people increased from 839 in 1999–2003 to 1059 in 2014–2018, median age increased from 37 to 47 years, the annual mortality rate decreased from 33.5 to 20.7 per 1000 person-years and the proportion of HIV-related deaths declined from 64% to 35%. HIV-related mortality declined from 21.4 to 7.3 (p < 0.001), while non-HIV-related mortality remained stable: 12.1 and 13.4 per 1000, respectively. Mortality decreased principally in persons diagnosed with AIDS-defining events. In the last decade, 2009–2018, mortality was still 8.1 times higher among HIV-infected people than in the general population, and even after excluding HIV-related deaths, remained 4.8 times higher. Excess mortality was observed in non-AIDS cancer (SMR = 3.7), cardiovascular disease (SMR = 4.2), respiratory diseases (SMR = 7.9), liver diseases (SMR = 8.8), drug abuse (SMR = 47), suicide (SMR = 5.3) and other external causes (SMR = 6). In conclusion, HIV-related mortality continued to decline, while non-HIV-related mortality remained stable. HIV-infected people maintained important excess mortality. Prevention of HIV infections in the population and promotion of healthy life styles in HIV-infected people must be a priority.

The Prevalence and Burden of Non-AIDS Comorbidities Among Women Living With or at Risk for Human Immunodeficiency Virus Infection in the United States.

The prevalence and burden of age-related non-AIDS comorbidities (NACMs) are poorly characterized among women living with HIV (WLWH). Virologically suppressed WLWH and HIV-seronegative participants followed in the Women's Interagency HIV Study (WIHS) through at least 2009 (when >80% of WLWH used antiretroviral therapy) were included, with outcomes measured through 31 March 2018. Covariates, NACM number, and prevalence were summarized at most recent WIHS visit. We used linear regression models to determine NACM burden by HIV serostatus and age. Among 3232 women (2309 WLWH, 923 HIV-seronegative) with median observation of 15.3 years, median age and body mass index (BMI) were 50 years and 30 kg/m2, respectively; 65% were black; 70% ever used cigarettes. WLWH had a higher mean NACM number than HIV-seronegative women (3.6 vs 3.0, P < .0001) and higher prevalence of psychiatric illness, dyslipidemia, non-AIDS cancer, kidney, liver, and bone disease (all P < .01). Prevalent hypertension, diabetes, and cardiovascular and lung disease did not differ by HIV serostatus. Estimated NACM burden was higher among WLWH versus HIV-seronegative women in those aged 40-49 (P < .0001) and ≥60 years (P = .0009) (HIV × age interaction, P = .0978). In adjusted analyses, NACM burden was associated with HIV, age, race, income, BMI, alcohol abstinence, cigarette, and crack/cocaine use; in WLWH, additional HIV-specific indices were not associated, aside from recent abacavir use. Overall, NACM burden was high in the cohort, but higher in WLWH and in certain age groups. Non-HIV traditional risk factors were significantly associated with NACM burden in WLWH and should be prioritized in clinical guidelines for screening and intervention to mitigate comorbidity burden in this high-risk population.

Multimorbidity in Elderly Persons According to the Year of Diagnosis of Human Immunodeficiency Virus Infection: A Cross-sectional Dat’AIDS Cohort Study

We assessed prevalence of multimorbidity (MM) according to year of human immunodeficiency virus (HIV) diagnosis in elderly people living with HIV (PLWH). This was a cross-sectional study of MM in PLWH aged ≥70 years from the Dat'AIDS French multicenter cohort. MM was defined as at least 3 coexistent morbidities of high blood pressure, diabetes mellitus, osteoporosis, non-AIDS cancer, chronic renal failure, cardiovascular and cerebrovascular disease, obesity, undernutrition, or hypercholesterolemia. Logistic regression models evaluated the association between MM and calendar periods of HIV diagnosis (1983-1996, 1997-2006, and 2007-2018). The secondary analysis evaluated MM as a continuous outcome, and a sensitivity analysis excluded PLWH with nadir CD4 count <200 cells/μL. Between January 2017 and September 2018, 2476 PLWH were included. Median age was 73 years, 75% were men, median CD4 count was 578 cells/μL, and 94% had controlled viremia. MM prevalence was 71%. HBP and hypercholesterolemia were the most prevalent comorbidities. After adjustment for age, gender, smoking status, hepatitis C and hepatitis B virus coinfection, group of exposure, nadir CD4 count, CD4:CD8 ratio, and last CD4 level, calendar period of diagnosis was not associated with MM (P = .169). MM was associated with older age, CD4/CD8 ratio <0.8, and nadir CD4 count <200 cells/μL. Similar results were found with secondary and sensitivity analyses. MM prevalence was high and increased with age, low CD4/CD8 ratio, and nadir CD4 count <200 cells/μL but was not associated with calendar periods of HIV diagnosis. Known duration of HIV diagnosis does not seem to be a criterion for selecting elderly PLWH at risk of MM.

A longitudinal study assessing differences in causes of death among housed and homeless people diagnosed with HIV in San Francisco

BackgroundSan Francisco has implemented several programs addressing the needs of two large vulnerable populations: people living with HIV and those who are homeless. Assessment of these programs on health outcomes is paramount for reducing preventable deaths.MethodsIndividuals diagnosed with HIV/AIDS and reported to the San Francisco Department of Public Health HIV surveillance registry, ages 13 years or older, who resided in San Francisco at the time of diagnosis, and who died between January 1, 2002, and December 31, 2016 were included in this longitudinal study. The primary independent variable was housing status, dichotomized as ever homeless since diagnosed with HIV, and the dependent variables were disease-specific causes of death, as noted on the death certificate. The Cochran-Armitage test measured changes in the mortality rates over time and unadjusted and adjusted Poisson regression models measured prevalence ratios (PR) and 95% confidence intervals (CI) for causes of death.ResultsA total of 4158 deceased individuals were included in the analyses: the majority were male (87%), ages 40–59 years old at the time of death (64%), non-Hispanic White (60%), men who have sex with men (54%), had an AIDS diagnosis prior to death (87%), and San Francisco residents at the time of death (63%). Compared to those who were housed, those who were homeless were more likely to be younger at time of death, African American, have a history of injecting drugs, female or transgender, and were living below the poverty level (all p values < 0.0001). Among decedents who were SF residents at the time of death, there were declines in the proportion of deaths due to AIDS-defining conditions (p < 0.05) and increases in accidents, cardiomyopathy, heart disease, ischemic disease, non-AIDS cancers, and drug overdoses (p < 0.05). After adjustment, deaths due to mental disorders (aPR = 1.63, 95% CI 1.24, 2.14) were more likely and deaths due to non-AIDS cancers (aPR = 0.63, 95% CI 0.44, 0.89) were less likely among those experiencing homelessness.ConclusionsAdditional efforts are needed to improve mental health services to homeless people with HIV and prevent mental-health related mortality.

977. The Prevalence and Burden of Non-AIDS Co-Morbidities in Women with or At-risk for HIV Infection in the United States

BackgroundAge-related non-AIDS comorbidities (NACM) increasingly account for morbidity and mortality in persons living with HIV. The burden of NACM and its association with HIV is poorly described in women.MethodsWe analyzed data from HIV+ and at-risk HIV− participants who were followed in the Women’s Interagency HIV Study (WIHS) after 2009 (when >80% of participants used antiretroviral therapy). The prevalence of each NACM (defined by a combination of self-report, clinical measurements, and laboratory data) and the number of NACM were summarized at a most recent follow-up visit and were compared by age and HIV serostatus using unadjusted linear regression models.ResultsThere were 3232 women (2309 HIV+, 923 HIV–) with a median follow-up of 15.3 years. The median age was 50 years, 65% were black, 38% currently smoked, 71% had ever used illicit drugs, 50% had annual income < $12,000, and median body mass index was 30 kg/m2. HIV+ women had a median CD4 count of 618 cells/mm3 and 66% had HIV viral suppression. Among 10 NACM evaluated, the following were more prevalent in HIV+ vs. HIV– women (all P < 0.01): psychiatric illness (57%/48%), liver disease (45%/26%), hyperlipidemia (40%/35%), bone disease (40%/33%), chronic kidney disease (15%/7%), and non-AIDS cancer (11%/7%). There was little difference in the prevalence of hypertension (66%/64%), lung disease (41%/43%), diabetes (22%/24%), and cardiovascular disease (19%/19%). Mean number of NACM was higher in HIV+ vs. HIV– women (3.6 vs. 3.0, P < 0.0001). Regardless of HIV serostatus, NACM burden significantly increased with age (P < 0.0001). Compared with women aged <40 of the same HIV serostatus, the estimated mean difference in NACM (HIV+/HIV–) for those 40–49, 50–59, ≥60 years was 1.1/0.7, 2.3/2.3, and 3.6/3.2, respectively (P < 0.0001 for all). Within-age-group comparisons revealed significantly greater NACM burden in HIV+ vs. HIV− women aged 40–49 years (P < 0.0001) and ≥60 years (P = 0.003), but not in those aged <40 or 50–59 years (HIV*age interaction P = 0.02) (figure).ConclusionNACM burden was high in both HIV+ and at-risk HIV– women, but higher in HIV+ women overall and in certain age groups. Accumulation of NACM has complex implications for clinical care, medication management, and healthcare screening that must be further examined in this population. DisclosuresAnandi N.

2515. Clinical Relevance of Immune Non-Response Among Virally Suppressed Adults Living with HIV in Africa and the United States

BackgroundImmune non-response (INR) for people living with HIV (PLWH) is the inability to regain healthy CD4 counts despite viral suppression (VS) on antiretroviral therapy (ART). We identified factors associated with INR in two methodologically similar but demographically diverse cohorts with open access to care and assessed the relationship between INR and incident serious non-AIDS event (SNAE).MethodsThe US Military HIV Natural History Study (NHS) and the African Cohort Study (AFRICOS) are multisite, open cohort studies enrolling PLWH. Participants with 2 years of VS < 400 copies/mL on ART were evaluated for INR, defined as CD4 < 350 cells/µL at 2 years VS. Logistic regression was used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for factors associated with INR. Cox proportional hazards regression produced adjusted hazard ratios (aHR) and 95% CIs for factors associated with incident SNAE (first non-AIDS cancer, cardiovascular, gastrointestinal, genitourinary, liver, musculoskeletal or respiratory event) after 2 years of VS.Results10.8% of the 1,784 NHS and 25.8% of the 984 AFRICOS subjects had INR. The AFRICOS cohort was older and had a higher proportion of females. In both cohorts, immune non-responders were significantly older and had a significantly lower CD4 at ART initiation. Those with INR also took longer to reach 2 years of VS since starting ART. Odds of INR decreased by over 60% for every 100 cell increase in baseline CD4 in both cohorts (NHS aOR = 0.31 [95% CI 0.26, 0.37]; AFRICOS aOR = 0.36 [95% CI 0.21, 0.86]). In the NHS, hazard of incident SNAE was 61% higher for those with INR (aHR = 1.61 [95% CI 1.12, 2.33]). Probability of SNAE-free survival at 15 years since 2 years of VS was approximately 20% lower comparing those with and without INR; nearly equal to the differences observed by 15-year age groups.ConclusionINR was common in two diverse cohorts with open access to care and treatment. The association with SNAEs suggests early identification of and interventions to prevent or reverse INR may improve clinical outcomes, but further study is needed. The clinical relevance of INR highlights the value of early HIV identification and treatment, and suggests CD4 monitoring at ART initiation and post-VS is important in settings where INR is prevalent.

2244. Non-AIDS Cancers Contribute to an Increasing Proportion of Deaths in Persons Living with HIV at a Single University-Based Clinic

BackgroundMortality for people living with HIV (PLWH) has drastically decreased since the mid-1990s, and the proportion of deaths due to non-HIV-related conditions has increased.MethodsDeceased PLWH were identified within a single academic medical center. Cause of death was determined by chart review, clinic providers, and when available autopsy and toxicology data. Chart review of comorbidities, demographics and preventable causes of cancer was conducted for deaths during the period of 2013–2017.ResultsThe proportion of AIDS-related deaths decreased markedly between 1995 and 2017, while the proportion of deaths from non-AIDS cancers has increased (figure). Patients with non-AIDS cancers were older, had a higher CD4 count and greater proportion with undetectable viral load, and were more likely to be male; over 80% were current or prior smokers (table). Among all deaths from 2013 to 2017, 44% of eligible patients received colon cancer screening, 66% received cervical cancer screening, and 29% received breast cancer screening. Of patients who died from HCC, one out of six had imaging for HCC within 1 year and none within 6 months of diagnosis.ConclusionImprovements in cancer screening and preventative health measures including smoking cessation and lifestyle improvement education may help to reduce the increasing proportion of non-AIDS cancer-related deaths among PLWH.

Early Treatment of Primary HIV Infection Is Associated with Decreased Mortality.

The aim of this study was to understand factors associated with increased mortality in a cohort of primary HIV infection (PHI) in New South Wales (NSW) over three decades. Six hundred and two patients with PHI were enrolled from 1984 to 2009. Probabilistic data linkage was performed to NSW Registry of births deaths and marriages and Australian Bureau of Statistics mortality database. Mortality was measured by crude death rate. Pre highly active antiretroviral therapy (pre-HAART) era was defined as before January 1, 1997. A Cox proportional hazard model was used to identify factors associated with death. One hundred and thirty-eight deaths occurred during 6,223 person years (PY) follow-up. Overall crude death rate was 2.2 per 100 PY (95% confidence interval [CI], 1.9-2.6), 3.6 (95% CI, 3.1-4.3)in pre-HAART era and 0.20 (95% CI, 0.08-0.47) in post-HAART era. AIDS was the most frequent cause of death (52%, 72/138), all occurring in the pre-HAART era. Of non-AIDS deaths, the leading known cause was non-AIDS cancer 8% (11/138) followed by suicide 4% (6/138). On multivariate analysis, estimated date of infection in pre-HAART era and time to commencement of ART greater than 1 year post diagnosis were more likely to be associated with death (p < .05). Mortality in PHI has decreased significantly in the post-HAART era. Non-AIDS deaths due to malignancy and suicide are emerging as leading causes in this population in the post-HAART era. Time to starting ART greater than 1 year was associated with increased mortality.

Hepatitis C-related hepatocellular carcinoma: diagnostic and therapeutic management in HIV-patients.

The efficacy of the current HIV therapy has led to increased survival and prolongation of the average life expectancy of people living with HIV (PLWH), as well as the emergence of comorbidities and non-AIDS related cancer. Hepatocellular carcinoma (HCC) is the most common primary liver malignancy. Current evidence suggests that HCC is an important cause of morbidity and mortality in HIV infected patients. In fact, HCC prevalence rate is indeed higher with respect to the general population average. In this paper, we review the diagnostic and therapeutic management of Hepatitis C-related hepatocellular carcinoma in HCV-HIV co-infected patients. Several therapeutic options are available depending on several factors as HCC stage, liver functions, comorbidities and they have been divided into three groups: potentially curative, proven effective but not curative, and unproven or ineffective therapy. In HIV-infected patients, surgical options are preferred compared to non-surgical therapies. Further studies, especially multicenter ones, are needed in order to define the most appropriate, evidence-based therapeutic approach to PLWH suffering from HCC. It also appears necessary to develop appropriate care guidelines for PLWH.

Changing temporal trends in non-AIDS cancer mortality among people diagnosed with AIDS: San Francisco, California, 1996–2013

BackgroundAntiretroviral therapy (ART) has reduced AIDS-defining cancer (ADC) mortality, but its effect on non-AIDS-defining cancer (NADC) mortality is unclear. To help inform cancer prevention and screening, we evaluated trends in NADC mortality among people with AIDS (PWA) in the ART era. MethodsThis retrospective cohort study analyzed AIDS surveillance data, including causes of death from death certificates, for PWA in San Francisco who died in 1996–2013. Proportional mortality ratios (PMRs), and year, age, race, sex-adjusted standardized mortality ratios (SMRs) were calculated for 1996–1999, 2000–2005, and 2006–2013, corresponding to advances in ART. ResultsThe study included 5822 deceased PWA of whom 90% were male and 68% were aged 35–54 at time of death. Over time, the PMRs significantly decreased for ADCs (2.6%, 1.4%, 1.2%) and increased for NADCs (4.3%, 7.0%, 12.3%). For all years combined (1996–2013) and compared to the California population, significantly elevated SMRs were observed for these cancers: all NADCs combined (2.1), anal (58.4), Hodgkin lymphoma (10.5), liver (5.2), lung/larynx (3.0), rectal (5.2), and tongue (4.7). Over time, the SMRs for liver cancer (SMR 19.8, 11.2, 5.0) significantly decreased while the SMRs remained significantly elevated over population levels for anal (SMR 123, 48.2, 45.5), liver (SMR 19.8, 11.2, 5.0), and lung/larynx cancer (SMR 5.3, 4.7, 3.6). ConclusionA decline in ADC PMRs and increase in NADC PMRs represent a shift in the cancer burden, likely due to ART use. Moreover, given their elevated SMRs, anal, liver, and lung/larynx cancer remain targets for improved cancer prevention, screening, and treatment.
