Incidence and long-term outcomes of the human immunodef?ciency virus neuroretinal disorder in patients with AIDS.

ABSTRACT: Patients with AIDS have an abnormality of retina/optic nerve function, manifested as decreased contrast sensitivity (in the absence of ocular opportunistic infections or media opacity), abnormalities on automated perimetry, and loss of retinal nerve fiber layer, even among those with good visual acuity, termed the "human immunodeficiency virus (HIV) neuroretinal disorder." The objectives of this study were to determine the prevalence, incidence, risk factors, and outcomes of HIV neuroretinal disorder.Prospective cohort study.A total of 1822 patients with AIDS without ocular infections or media opacities.Patients with HIV neuroretinal disorder were identified by a contrast sensitivity <1.50 log units in either eye in the absence of ocular opportunistic infections or media opacity.Incidence of HIV neuroretinal disorder, mortality, visual impairment (visual acuity ?20/50), and blindness (?20/200) on logarithmic visual acuity charts.Sixteen percent of participants had HIV neuroretinal disorder at enrollment. The estimated cumulative incidence by 20 years after AIDS diagnosis was 51% (95% confidence interval [CI], 46-55). Human immunodeficiency virus neuroretinal disorder was more common in women and African Americans. Risk factors for HIV neuroretinal disorder included hepatitis C infection, low CD4+ T cells, and detectable HIV RNA in the blood. Patients with HIV neuroretinal disorder had a 70% excess mortality versus those without it, even after adjusting for CD4+ T cells and HIV load (hazard ratio [HR], 1.7; 95% CI, 1.3-2.1; P < 0.0001). Patients with HIV neuroretinal disorder had increased risks of bilateral visual impairment (HR, 6.5; 95% CI, 2.6-10.6; P < 0.0001) and blindness (HR, 5.9; 95% CI, 2.8-13.7; P = 0.01) versus those without HIV neuroretinal disorder.Human immunodeficiency virus neuroretinal disorder is a common finding among patients with AIDS, and it is associated with an increased mortality and an increased risk of visual impairment. Successful antiretroviral therapy decreases but does not eliminate the risk of HIV neuroretinal disorder.

Project description:ObjetivesOutcomes of people living with HIV (PLWH) developing non-AIDS events (NAEs) remain poorly defined. We aimed to classify NAEs according to severity, and to describe clinical outcomes and prognostic factors after NAE occurrence using data from CoRIS, a large Spanish HIV cohort from 2004 to 2013.DesignProspective multicenter cohort study.MethodsUsing a multistate approach we estimated 3 transition probabilities: from alive and NAE-free to alive and NAE-experienced ("NAE development"); from alive and NAE-experienced to death ("Death after NAE"); and from alive and NAE-free to death ("Death without NAE"). We analyzed the effect of different covariates, including demographic, immunologic and virologic data, on death or NAE development, based on estimates of hazard ratios (HR). We focused on the transition "Death after NAE".Results8,789 PLWH were followed-up until death, cohort censoring or loss to follow-up. 792 first incident NAEs occurred in 9.01% PLWH (incidence rate 28.76; 95% confidence interval [CI], 26.80-30.84, per 1000 patient-years). 112 (14.14%) NAE-experienced PLWH and 240 (2.73%) NAE-free PLWH died. Adjusted HR for the transition "Death after NAE" was 12.1 (95%CI, 4.90-29.89). There was a graded increase in the adjusted HRs for mortality according to NAE severity category: HR (95%CI), 4.02 (2.45-6.57) for intermediate-severity; and 9.85 (5.45-17.81) for serious NAEs compared to low-severity NAEs. Male sex (HR 2.04; 95% CI, 1.11-3.84), age>50 years (1.78, 1.08-2.94), hepatitis C-coinfection (2.52, 1.38-4.61), lower CD4 cell count at cohort entry (HR 2.49; 95%CI 1.20-5.14 for CD4 cell count below 200 and HR 2.16; 95%CI 1.01-4.66 for CD4 cell count between 200-350, both compared to CD4 cell count higher than 500) and concomitant CD4<200 cells/mL (2.22, 1.42-3.44) were associated with death after NAE. CD4 count and HIV-1 RNA at engagement, previous AIDS and hepatitis C-coinfection predicted mortality in NAE-free persons.ConclusionNAEs, including low-severity events, increase prominently the risk for mortality in PLWH. Prognostic factors differ between NAE-experienced and NAE-free persons. These findings should be taken into account in the clinical management of PLWH developing NAEs and may permit more targeted prevention efforts.

Project description:BackgroundHypertensive disorders of pregnancy (HDP) are associated with increased risks for cardiovascular disease later in life. The HDP incidence is commonly assessed using diagnostic codes, which are not reliable; and typically are expressed per-pregnancy, which may underestimate the number of women with an HDP history after their reproductive years.ObjectivesThis study sought to determine the incidence of HDP expressed as both per-pregnancy and per-woman, and to establish their associations with future chronic conditions and multimorbidity, a measure of accelerated aging, in a population-based cohort study.MethodsUsing the Rochester Epidemiology Project medical record-linkage system, the authors identified residents of Olmsted County, Minnesota, who delivered between 1976 and 1982. The authors classified pregnancies into normotensive, gestational hypertension, pre-eclampsia, eclampsia, pre-eclampsia superimposed on chronic hypertension, and chronic hypertension using a validated electronic algorithm, and calculated the incidence of HDP both per-pregnancy and per-woman. The risk of chronic conditions between women with versus those without a history of HDP (age and parity 1:2 matched) was quantified using the hazard ratio and corresponding 95% confidence interval estimated from a Cox model.ResultsAmong 9,862 pregnancies, we identified 719 (7.3%) with HDP and 324 (3.3%) with pre-eclampsia. The incidence of HDP and pre-eclampsia doubled when assessed on a per-woman basis: 15.3% (281 of 1,839) and 7.5% (138 of 1,839), respectively. Women with a history of HDP were at increased risk for subsequent diagnoses of stroke (hazard ratio [HR]: 2.27; 95% confidence interval [CI]: 1.37 to 3.76), coronary artery disease (HR: 1.89; 95% CI: 1.26 to 2.82), cardiac arrhythmias (HR: 1.62; 95% CI: 1.28 to 2.05), chronic kidney disease (HR: 2.41; 95% CI: 1.54 to 3.78), and multimorbidity (HR: 1.25; 95% CI: 1.15 to 1.35).ConclusionsThe HDP population-based incidence expressed per-pregnancy underestimates the number of women affected by this condition during their reproductive years. A history of HDP confers significant increase in risks for future chronic conditions and multimorbidity.
