Abstract
Few population-based studies have looked at the risk of uveitis among syphilis patients. Our study addresses the knowledge gap by reporting on uveitis risk in syphilis patients through a retrospective cohort study. The Taiwan National Health Insurance database was used for this study, covering the period from January 1st, 2009, to December 31st, 2020. We created a 1:4 propensity score matched cohort between the syphilis patients and controls, which accounted for gender, age, and comorbidities. The primary endpoint was the incidence of newly recorded uveitis. The assessment of uveitis risk in syphilis patients included the use of the Kaplan-Meier method and multivariate Cox proportional hazard model. A total of 31,597 syphilis patients and 126,379 matched comparisons were recruited. The uveitis incidence rate from our syphilis patients was 1.25 per 1000 person-years. The uveitis incidence rate from our non-syphilis group was 0.8 per 1000 person-years. After matching, the syphilis group was found to have a higher risk of developing uveitis (adjusted hazard ratio (aHR) [95% CI]: 1.57 [1.36-1.81], P < .001). Among males and individuals aged 20-34 years, subgroup analysis showed an increased risk of uveitis in the presence of syphilis infection. The Kaplan-Meier survival curve showed a significant difference in uveitis incidence between syphilis and non-syphilis groups (log-rank test P < .001). In summary, our study revealed that Taiwanese syphilis patients were at a higher risk of developing uveitis. These results highlight the need for regular ocular monitoring and screening in individuals with syphilis.

Abstract
It is critical to understand health care engagement and utilization among older persons living with HIV (OPWH) who may have greater burden for non-communicable diseases. Following the PRISMA guidelines, a systematic review using 5 electronic databases was conducted to appraise and synthesize the current literature on the relationship of non-communicable diseases on engagement in care and health care utilization among OPWH. Original studies published in English between 2009 and 2019 were included, yielding 16 relevant articles. Overall, having co-morbid non-communicable diseases was associated with a decreased likelihood of initiating and adhering to ART. Being on ART and viral suppression were associated with better engagement in non-communicable disease care. Findings also suggest that an increasing number of co-morbidities is associated with higher health care utilization and financial burden. This review underscores the need for preventing and managing co-morbidities to enhance engagement in HIV care and that health care practitioners need to ensure that OPWH are engaged in care for both HIV and their co-morbid conditions by providing coordinated and integrated care.

BMC Infect Dis 2018; 18:168. [PMID: 29636023 PMCID: PMC5894176 DOI: 10.1186/s12879-018-3083-z] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2017] [Accepted: 04/04/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Little is known about the clinical presentation and outcomes amongst older HIV infected populations accessing ART in sub-Saharan Africa. We compared mortality amongst HIV infected patients accessing ART that were < 50 years to those ≥50 years in Kwa-Zulu Natal, South Africa. METHODS We undertook a retrospective review of medical records of patients that accessed HIV services at the CAPRISA AIDS Treatment program (CAT) between June 2004 to December 2012 (N = 4003). HIV infected patients, 14 years or older were enrolled. All-cause mortality and treatment response to ART in those < 50 years to those ≥50 years were compared. A Kaplan-Meier curve and log-rank test were used to compare the cumulative probability of death between the two age groups with the primary endpoint being mortality. Statistical analysis was done using SAS (version 9.4.; SAS Institute Inc., Cary, NC, USA). RESULTS Of 4003 individuals, 262 (6.5%) were ≥ 50 years (older group). The median age in those ≥50 years and < 50 year was 54.5 and 32.0 years, respectively. The younger group was mainly female (64.7%). There was no difference in mortality rate, between the older (6.9/100 person-years (py), 95% confidence interval (CI): 4.7-9.6) and younger group (5.3/100 py, 95% CI: 4.7-5.8) at 60 months (p = 0.137). In the multivariable model older patients had a significantly higher risk of death compared to younger patients. (hazard ratio (HR) 1.60, 95% CI: 1.08-2.39, p = 0.019).The rate of CD4+ cell count increase was higher in those < 50 years (β = 0.34, 95% CI: 0.19-0.50, p < 0.001) with no difference in viral suppression. The older group showed significantly higher prevalence of diabetes (6.3%) and hypertension (21.5%), p < 0.001. CONCLUSION ART initiation in older HIV infected patients was associated with a higher mortality compared to those younger than 50 years. ART immunological response was less robust in older individuals. The increase in hypertension and diabetes among older patients suggests the need to restructure and integrate primary and specialized health care services into ART services.

Abstract
Objective: Bone mineral density (BMD) loss, a risk factor for osteoporosis, has been attributed to HIV infection and antiretroviral therapy (ART), including regimens containing tenofovir disoproxil fumarate. Design: Study 202094 is an open-label, parallel-group, sub-study of the phase III SWORD-1 and SWORD-2 studies (ClinicalTrials.gov identifier, NCT02478632). Methods: HIV-1-infected adults with HIV-1 RNA less than 50 copies/ml who received ART containing tenofovir disoproxil fumarate for at least 6 months were randomized to receive dolutegravir with rilpivirine or continue current ART regimen. Total hip and lumbar spine BMD were measured by dual-energy X-ray absorptiometry (DXA) scans. The primary endpoint was percentage change from baseline in total hip BMD. Results: DXA scans were evaluable for 81 participants at baseline and Week 48. Percentage increase in total hip BMD was significantly greater in participants who switched to dolutegravir with rilpivirine (1.34%) compared with participants who continued current ART (0.05%; treatment difference, +1.29%; 95% CI 0.27–2.31; P = 0.014). Lumbar spine BMD significantly increased in the dolutegravir with rilpivirine group by 1.46% (95% CI 0.65–2.28) compared with 0.15% (95% CI –0.79 to 1.09) in the current ART group (treatment difference, 1.32; 95% CI 0.07–2.57; P = 0.039). Participants in the dolutegravir with rilpivirine group experienced significantly greater reductions in bone formation and resorption biomarkers compared with the current ART group. Conclusion: Switch to dolutegravir with rilpivirine was associated with significant improvement in BMD and bone turnover markers compared with tenofovir-based three-drug regimens, providing a robust option for preserving bone health while continuing suppressive ART.

Abstract
Since the introduction of combined antiretroviral therapy (cART) and more effective treatments for AIDS, there has been a dramatic shift from the weight loss and wasting that characterised HIV/AIDS (and still does in countries where cART is not readily available or is initiated late) to healthy weight, or even overweight and obesity at rates mirroring those seen in the general population. These trends are attributable to several factors, including the "return to health" weight gain with reversal of the catabolic effects of HIV-infection following cART-initiation, strategies for earlier cART-initiation in the course of HIV-infection which have prevented many people living with HIV-infection from developing wasting, in addition to exposure to the modern obesogenic environment. Older cART regimens were associated with increased risk of body fat partitioning disorders (lipodystrophy) and cardiometabolic complications including atherothrombotic cardiovascular disease (CVD) and diabetes mellitus. Whilst cART now avoids those medications implicated in causing lipodystrophy, long-term cardiometabolic data on more modern cART regimens are lacking. Longitudinal studies show increased rates of incident CVD and diabetes mellitus with weight gain in treated HIV-infection. Abdominal fat gain, weight gain, and rising body mass index (BMI) in the short-term during HIV treatment was found to increase incident diabetes risk. Rising BMI was associated with increased risk of incident CVD, however the relationship varied depending on pre-cART BMI category. In contrast, a protective association with mortality is evident, predominantly in the underweight and in resource-poor settings, where weight gain reflects access to cART and virological suppression. The question of how to best evaluate, manage (and perhaps constrain) weight gain during HIV treatment is of clinical relevance, especially in the current climate of increasingly widespread cART use, rising overweight, and obesity prevalence and growing metabolic and cardiovascular disease burden in people living with HIV-infection. Large prospective studies to further characterise the relationship between weight gain during HIV treatment and risk of diabetes, CVD and mortality are required.

Abstract
Objectives Thanks to the success of combination antiretroviral therapy (cART), HIV‐infected patients can have almost a normal life expectancy. This has resulted in an aging HIV‐infected population with other chronic comorbidities such as cardiovascular diseases, osteoporosis, and depression. Our hypothesis is that patients' perceptions of and attitudes towards their cART, which is perceived as crucial to their survival, differ from their beliefs about their co‐treatments, and this may have an impact on their medication adherence. Methods We used the French version of the Beliefs about Medicine Questionnaire (BMQ‐f) to measure the perceptions of patients about their co‐treatments and the Beliefs about Medicine Questionnaire for Highly Active Antiretroviral Therapy (BMQ‐HAART) to measure their beliefs about their cART in a representative sample (n = 150) of patients enrolled in the Swiss HIV Cohort Study (SHCS) and followed at the Infectious Disease Service at the University Hospital in Lausanne, Switzerland. The survey was administered to all eligible patients by the order of their scheduled appointments at the end of their medical visit. The BMQ comprises two subscores: Specific‐Necessity (5 identical items in BMQ‐f and BMQ‐HAART) and Specific‐Concerns (also 5 identical items in BMQ‐f and BMQ‐HAART). The subscores were standardized by dividing the score scale by the number of questions in the scale, resulting in a range of responses between 1 (low) and 5 (high). Self‐reported medication adherence was measured using the SHCS Adherence Questionnaire (SHCS‐AQ). Adherence was defined as not missing any dose or missing one dose of the treatment in the past 4 weeks. Sociodemographic variables were retrieved by reviewing the SHCS database. Results A response rate of 73% (109 of 150) was achieved. A total of 105 patients were included in the analysis: their median age was 56 [interquartile range (IQR) 51, 63] years and 74 were male (70%). Eighty‐seven patients (83%) were adherent to cART and 75 (71%) were adherent to their co‐treatments (P = 0.0001). The standardized mean responses for the BMQ Specific‐Necessity subscores were 4.46 [standard deviation (SD): 0.58] and 2.86 (SD: 1.02) for cART and co‐treatments, respectively (P < 0.0001). For Specific‐Concerns, the standardized mean responses were 2.9 (SD: 1.02) for cART and 4.09 (SD: 1.02) (P < 0.0001) for co‐treatments. cART and co‐treatment concerns increased as the number of co‐treatments increased (P = 0.03 and P < 0.0001, respectively). Conclusions Patients had higher Necessity and lower Concerns scores for their cART in comparison with their co‐treatments. A higher percentage of patients reported being adherent to cART compared with the co‐treatments that they reported they were most likely to miss. Further research using a bigger sample size and more objective measures of adherence is needed to explore the association between adherence and patients' perceptions.

Abstract
CONTEXT AND OBJECTIVE: A search in the SciELO and PubMed databases showed few studies on human immunodeficiency virus (HIV) positive individuals in long-term care institutions (LTCIs), thus prompting the present study. The aim of this study was to ascertain whether there were any HIV-positive individuals in LTCIs for the elderly. DESIGN AND SETTING: Cross-sectional study in which the Hospital Infection Control Committee (HICC) of a 405-bed LTCI was consulted. METHODS: The medical records of 405 individuals interned in the LTCI who had been tested for HIV infection were requested for analysis of the following variables: [1] age and gender; [2] length of stay at LTCI (months); [3] causes and diagnoses on admission to LTCI according to International Classification of Diseases, 10th edition; [4] date of HIV diagnosis; [5] seropositivity for syphilis and hepatitis B and C viruses; [6] medications used at last prescription in medical file; and [7] mean CD4 lymphocyte count based on: total lymphocyte count/6 and total lymphocyte count x 0.8 x 0.2 or 0.3. RESULTS: Four men were HIV-positive, with mean age 71.2 ± 8.6 years, LTCI stay 74.2 ± 38.1 months and length of HIV diagnosis 24.5 ± 17 months (confirmed by HICC standard screening). Three had stroke sequelae; one, dementia syndrome; two, seropositivity for syphilis; two, hepatitis B and one, hepatitis C. The main drugs used were lamivudine, zidovudine, lopinavir, ritonavir, levothyroxine, omeprazole, ranitidine, lactulose and risperidone. The estimated CD4 count was 341 ± 237/mm3. CONCLUSIONS: HIV-positive individuals are present in LTCIs, diagnosable through serological screening and treatable with antiretroviral drugs.

Abstract
: Antiretroviral therapy initiation is associated with declines in bone mineral density (BMD), which seem greatest with tenofovir disoproxil fumarate (DF)-containing regimens. Data comparing protease inhibitors are limited. This CASTLE substudy compared paired baseline with week 96 BMD in patients initiating tenofovir DF/emtricitabine plus atazanavir/ritonavir (n = 106) vs lopinavir/ritonavir (n = 70). In both groups, week 96 BMD declined significantly in arm, leg, trunk, and total body regions. Atazanavir/ritonavir was associated with smaller 96-week trunk and total body BMD declines compared with lopinavir/ritonavir [multivariate-adjusted least squares mean difference +2.00% (95% confidence interval: 0.52 to 3.45; P = 0.008) and +1.24% (95% confidence interval: 0.13 to 2.35; P = 0.029), respectively]. In addition, low baseline CD4 cell count (<50 cells per microliter) and increasing age were associated with larger declines in BMD.

Abstract
Objectives: Increasing life expectancy of HIV-1–infected patients raises interest in how trial results apply to
older patients. This post-hoc analysis evaluated potential differences in efficacy and safety in older (≥50 years) versus
younger (<50 years) patients in the ECHO and THRIVE trials over 96 weeks. Methods: HIV-infected, treatment-naÏve adults were randomized to receive rilpivirine (RPV) or efavirenz (EFV), plus a
background regimen. Virologic response rates (FDA snapshot analysis; HIV-1 RNA <50 copies/mL) were assessed at
Week 96. Total-body bone mineral density was evaluated at baseline and Week 96 by dual-energy X-ray absorptiometry
scans. Serum concentrations of 25-hydroxy vitamin D (ECHO trial only) were also measured at baseline, Week 24 and
Week 48. Results: 1368 patients were treated. At Week 96, virologic response rates were similar between older (77%) and younger
(76%) RPV-treated patients and numerically higher in older (84%) versus younger (76%) EFV-treated patients. No
clinically relevant age-related differences were observed in immunologic responses. Small differences were noted in older
versus younger patients in adverse events (higher rates of depression, insomnia, and rash in older EFV-treated patients),
laboratory abnormalities (increased low-density lipoprotein cholesterol and hyperglycemia in older EFV-treated patients
and increased amylase in older patients across treatments), bone mineral density (larger decreases in older patients across
treatments), and progression to severe vitamin D deficiency (greater in older versus younger EFV-treated patients). Conclusion: Efficacy and safety outcomes were generally similar in older versus younger patients in the ECHO and
THRIVE trials.

Abstract
BACKGROUND With the reorganization of primary care into Patient Aligned Care Teams (PACT) teams, the Veteran Affairs Health System (VA) aims to ensure all patients receive care based on patient-centered medical home (PCMH) principles. However, some patients receive the preponderance of care from specialty rather than primary care clinics because of the special nature of their clinical conditions. We examined seven VA (HIV) clinics as a model to test the extent to which such patients receive PCMH-principled care. OBJECTIVE To examine the extent to which HIV specialty care in VA conforms to PCMH principles. DESIGN Qualitative study. PARTICIPANTS Forty-one HIV providers from seven HIV clinics and 20 patients from four of these clinics. APPROACH We conducted semi-structured interviews with HIV clinic providers and patients about care practices and adherence to PCMH principles. Using an iterative approach, data was analyzed using both a content analysis and an a priori, PCMH-principled coding strategy. KEY RESULTS Patients with HIV receive varying levels of PCMH-principled care across a range of VA HIV clinic structures. The more PCMH-principled HIV clinics largely functioned as PCMHs; patients received integrated, coordinated, comprehensive primary care within a dedicated HIV clinic. In contrast, some clinics were unable to meet the criteria of being a patient's medical home, and instead functioned primarily as a place to receive HIV-related services with limited care coordination. Patients from the less PCMH-principled clinics reported less satisfaction with their care. CONCLUSIONS Even in a large, integrated healthcare system, there is wide variation in patients' receipt of PCMH-principled care in specialty care settings. In order to meet the goal of having all patients receiving PCMH-principled care, there needs to be careful consideration of where primary and specialty care services are delivered and coordinated. The best mechanisms for ensuring that patients with complex medical conditions receive PCMH-principled care may need to be tailored to different specialty care contexts.

Abstract
Self-managing HIV/AIDS presents challenges for anyone infected. These challenges may be further complicated for older HIV-infected African American women who acquired the disease at younger ages and now have co-morbidities. Little is known regarding how women's age identity, social responsibilities, co-morbidities, and romantic relationship status influence their HIV self-management. Five focus groups were conducted in Washington DC, with HIV-positive African American women aged 52-65. Topics included HIV and co-morbidity self-management, social support needs, medication adherence, and future plans for old age. A constant comparison approach was applied during data analysis. Co-morbidities, including diabetes and hypertension, were perceived to be more difficult to self-manage than HIV. This difficulty was not attributed to aging but to daily struggles such as lack of income and/or health insurance, an inflexible work schedule, and loneliness. Social responsibilities, including caring for family, positively impacted participants' ability to self-manage HIV by serving as motivation to stay healthy in order to continue to help family members. In contrast, inflexible work schedules negatively impacted women's ability to sustain medication adherence. Overall, this study demonstrates that HIV and co-morbidity self-management are inextricably linked. We can no longer afford to view engagement in HIV care as a single-disease issue and hope to attain optimal health and well-being in our HIV-affected populations. Optimal HIV self-management must be framed within a larger context that simultaneously addresses HIV and co-morbidities, while considering how social and cultural factors uniquely intersect to influence older African American women's self-management strategies.

Abstract
The mechanisms of autonomic imbalance and subsequent cardiovascular manifestations in HIV-1-infected patients are poorly understood. We report here that HIV-1 transactivator of transcription (Tat, fragment 1-86) produced a concentration-dependent increase in cytosolic Ca(2+) in cardiac-projecting parasympathetic neurons of nucleus ambiguus retrogradely labeled with rhodamine. Using store-specific pharmacological agents, we identified several mechanisms of the Tat-induced Ca(2+) elevation: 1) lysosomal Ca(2+) mobilization, 2) Ca(2+) release via inositol 1,4,5-trisphosphate-sensitive endoplasmic reticulum pools, and 3) Ca(2+) influx via transient receptor potential vanilloid type 2 (TRPV2) channels. Activation of TRPV2, nonselective cation channels, induced a robust and prolonged neuronal membrane depolarization, thus triggering an additional P/Q-mediated Ca(2+) entry. In vivo microinjection studies indicate a dose-dependent, prolonged bradycardic effect of Tat administration into the nucleus ambiguus of conscious rats, in which neuronal TRPV2 played a major role. Our results support previous studies, indicating that Tat promotes bradycardia and, consequently, may be involved in the QT interval prolongation reported in HIV-infected patients. In the context of an overall HIV-dependent autonomic dysfunction, these Tat-mediated mechanisms may account for the higher prevalence of sudden cardiac death in HIV-1-infected patients compared with general population with similar risk factors. Our results may be particularly relevant in view of the recent findings that significant Tat levels can still be identified in the cerebrospinal fluid of HIV-infected patients with viral load suppression due to efficient antiretroviral therapy.

Abstract
BACKGROUND The improved survival of subjects with human immunodeficiency virus (HIV) has been accompanied by an increased prevalence of chronic kidney disease (CKD). Epidemic of CKD among those with HIV has not yet been evaluated in multiple tertiary hospitals in Japan. METHODS A cross-sectional study was conducted in 2011 at Tokyo Metropolitan Komagome Hospital (TMKH) and Tokyo Medical University Hospital (TMUH). A total of 1482 HIV-infected subjects (1384 men, 98 female, mean age: 44.2 +/- 11.4 years old) were consecutively enrolled in the study. Random urine and blood samples were collected to study prevalence of CKD. CKD was diagnosed as a decrease in glomerular function and/or proteinuria and classified into 5 stages based on National Kidney Foundation guidelines. The estimated glomerular filtration rate based on serum creatinine was calculated using the 3-variable equation, constructed by the Japanese Society of Nephrology. Proteinuria was defined as > or = 1+ on urine dipstick examination. All electronic medical charts were reviewed to determine comorbidities, including hypertension and diabetes mellitus (DM). The proportion of subjects receiving tenofovir disoproxil fumarate (TDF) was investigated. Risk factors for CKD were determined using multivariate logistic regression analysis. RESULTS The mean CD4 cell count was 487 +/- 216/microL and 80.5% had undetectable HIV-RNA level in the combined cohort. Of the 90.2% of subjects taking antiretroviral agents, 61.5% was using TDF. The prevalence of overall CKD and CKD > or = stage 3 was 12.9% and 6.7%, respectively, both of which were nearly 3-fold higher in the TMKH cohort (p < .0001). Mean age and proportional prevalent hypertension and DM were significantly higher in the TKMH cohort than in the TMUH cohort. Multivariate analysis showed significant CKD to be associated with age > or =50 years (odds ratio [OR], 2.81), hypertension (OR, 3.04), and DM (OR, 2.05). CONCLUSIONS CKD prevalence was 12.9% among combined cohorts, but differed significantly between them. Differences in age distribution and the proportion of comorbidities, including hypertension and DM, are likely involved.

Abstract
Propensity for developing coronary heart disease (CHD) is linked with Framingham-defined cardiovascular risk factors and elevated inflammatory biomarkers. Cardiovascular risk and inflammatory biomarkers were evaluated in ARIES, a Phase IIIb/IV clinical trial in which 515 antiretroviral-naive HIV-infected subjects initially received abacavir/lamivudine + atazanavir/ritonavir for 36 weeks. Subjects who were virologically suppressed by week 30 were randomized 1:1 at week 36 to either maintain or discontinue ritonavir for an additional 108 weeks. Framingham 10-year CHD risk scores (FRS) and risk category of <6% or ≥6%, lipoprotein-associated phospholipase A(2) (Lp-PLA(2)), interleukin-6 (IL-6), and high-sensitivity C-reactive protein (hsCRP) were assessed at baseline, week 84, and week 144. Biomarkers were stratified by FRS category. When ritonavir-boosted/nonboosted treatment groups were combined, median hsCRP did not change significantly between baseline (1.6 mg/liter) and week 144 (1.4 mg/liter) in subjects with FRS <6% (p=0.535) or with FRS ≥6% (1.9 mg/liter vs. 2.0 mg/liter, respectively; p=0.102). Median IL-6 was similar for subjects with FRS <6% (p=0.267) at baseline (1.6 pg/ml) and week 144 (1.4 pg/ml) and for FRS ≥6% (2.0 pg/ml vs. 2.2 pg/ml, respectively; p=0.099). Median Lp-PLA(2) decreased significantly (p<0.001) between baseline (197 nmol/min/ml) and week 144 (168 nmol/min/ml) in subjects with FRS <6% and with FRS ≥6% (238 nmol/min/ml vs. 175 nmol/min/ml, respectively; p<0.001). In conclusion, in antiretroviral-naive subjects treated with abacavir-based therapy for 144 weeks, median inflammatory biomarker levels for hsCRP and IL-6 generally remained stable with no significant difference between baseline and week 144 for subjects with either FRS <6% or FRS ≥6%. Lp-PLA(2) median values declined significantly over 144 weeks for subjects in either FRS stratum.

Abstract
HIV infections are a growing concern in the elderly as a result of improvements in therapeutics and monitoring, which have extended the life span for this HIV-infected population. Elderly patients potentially are more complicated to treat than younger HIV-infected individuals because of comorbidities and the physiological effects of aging on pharmacokinetics and pharmacodynamics. The patient, a 67-year-old African-American HIV-infected male, presents to the transitional care unit of university-affiliated hospital refusing to take medications and undergo laboratory testing, including blood draws. This patient's treatment is further complicated by poor renal function, medications with potential interactions, and a recent diagnosis of depression. This case demonstrates treatment and monitoring of an elderly patient with HIV and reveals the complications associated with this disease state. Specifically, it identifies nonadherence to medications and a lack of laboratory results, which affect the efficacy of treatment and monitoring, medication adjustments based on metabolism and renal excretion, monitoring of adverse effects of HIV and antiretroviral therapy, and comorbid conditions that may be linked to HIV and antiretroviral therapy such as depression and bone disease. Education on HIV medications, monitoring, and standards of care for pharmacists working with the geriatric population is warranted and should be emphasized as the HIV-infected elderly population continues to grow.

Abstract
Background Although highly active antiretroviral therapy (HAART) has improved HIV survival, some patients receiving therapy are still dying. This analysis was conducted to identify factors associated with increased risk of post-HAART mortality. Methods We evaluated baseline (prior to HAART initiation) clinical, demographic and laboratory factors (including CD4+ count and HIV RNA level) for associations with subsequent mortality in 1,600 patients who began HAART in a prospective observational cohort of HIV-infected U.S. military personnel. Results Cumulative mortality was 5%, 10% and 18% at 4, 8 and 12 years post-HAART. Mortality was highest (6.23 deaths/100 person-years [PY]) in those with ≤ 50 CD4+ cells/mm3 before HAART initiation, and became progressively lower as CD4+ counts increased (0.70/100 PY with ≥ 500 CD4+ cells/mm3). In multivariate analysis, factors significantly (p < 0.05) associated with post-HAART mortality included: increasing age among those ≥ 40 years (Hazard ratio [HR] = 1.32 per 5 year increase), clinical AIDS events before HAART (HR = 1.93), ≤ 50 CD4+ cells/mm3 (vs. CD4+ ≥ 500, HR = 2.97), greater HIV RNA level (HR = 1.36 per one log10 increase), hepatitis C antibody or chronic hepatitis B (HR = 1.96), and HIV diagnosis before 1996 (HR = 2.44). Baseline CD4+ = 51-200 cells (HR = 1.74, p = 0.06), and hemoglobin < 12 gm/dL for women or < 13.5 for men (HR = 1.36, p = 0.07) were borderline significant. Conclusions Although treatment has improved HIV survival, defining those at greatest risk for death after HAART initiation, including demographic, clinical and laboratory correlates of poorer prognoses, can help identify a subset of patients for whom more intensive monitoring, counseling, and care interventions may improve clinical outcomes and post-HAART survival.
