Relationship between Human Immunodeficiency Virus Neuroretinal Disorder and Vision-Specific Quality of Life among People with AIDS

Functional and structural neuroretinal disorders in HIV Controllers. Prospective cohort study

OBJECTIVE

To estimate the prevalence and cumulative incidence of neuro-retinal-disorders (NRD) in HIV-controllers.

DESIGN

Prospective, single-centre, cohort study of people living with HIV (PLWH): elite-controllers, long-term-non-progressors and early diagnosed.

METHODS

The study compared "HIV-controllers" (including elite-controllers and long-term-non-progressors), who were not on antiretroviral therapy (ART), and "HIV-treatment" (HIV-infected subjects with a recent diagnosis and on ART). A matched cohort of "non-HIV subjects" was created. NRD was defined as at least one altered (not normal) ophthalmological parameter (functional or structural). Functional (visual acuity, contrast sensitivity, chromatic vision, visual field) and structural parameters (ganglion cells, macular nerve fibre layer, peripapillary nerve fibre layers, vascular calibre) as well as quality of life (Medical Outcomes Study-HIV Short Form-30) were assessed.

RESULTS

Between March 2012 and November 2015, the study included all HIV-controllers (16 elite-controllers, 1 long-term-non-progressor), 11 HIV-treatment and 16 non-HIV. Prevalence of NRD at baseline was 88.2% (15/17, 95% CI: 65.7%-96.7%), 90.9% (10/11, 95% CI: 62.3%-98.4%) and 56.3% (9/16, 95% CI: 33.2%-76.9%), respectively. Cumulative incidence at 3 years was 50% (1/2), 100% (1/1) and 33.3% (2/6), respectively. None of the participants manifested ocular clinical symptoms. Three years later, prevalence of NRD was 92.3% (12/13, 95% CI: 66.7%-98.6%), 75% (6/8, 95% CI: 40.9%-92.9%) and 50.0% (7/14, 95% CI: 26.8%-73.2%), respectively. Contrast sensitivity and structural parameters were globally the most affected among PLWH. Quality of life (total score) [median (interquartile range)] at baseline and 3 years was 82 (71-89) and 74 (63.5-79.25) in HIV-controllers and 80 (73-88) and 88 (83-92) in HIV-treatment.

CONCLUSIONS

HIV-controllers and those individuals on ART presented a higher percentage of NRD than non-HIV. Our results suggest that NRD could be a biomarker of ocular aging among PLWH.

Vision-Related Quality of Life and Association Between Retinal Parameters in Patients with Non-Arteritic Anterior Ischemic Optic Neuropathy

Purpose

To evaluate visual-related quality of life (VR-QoL) and its association with optic nerve head microvasculature in individuals with nonarteritic anterior ischemic optic neuropathy (NAION) evaluated at the acute stage.

Methods

In this retrospective case-control study, 23 NAION eyes at the acute stage and 25 age and gender matched healthy eyes were included, respectively. All included eyes underwent a complete ophthalmic examination including optical coherence tomography (OCT) and OCT angiography (OCTA). The Chinese version of the National Eye Institute Visual Function Questionnaire-25 (CHI-NEI-VFQ-25) was applied to assess VR-QoL in individuals consecutively visited at an ophthalmic center. Descriptive and analytic statistics were employed.

Results

There were no significant differences on age, gender, socioeconomic and education level (P > 0.05), but best-corrected visual acuity (BCVA) differences were reported between cases and controls (P < 0.05). Each peripapillary retinal nerve fiber layer (RNFL) thickness was higher but peripapillary vessel density (VD) and VR-QoL scores for all subscales were significantly lower in cases when compared with controls, respectively (P < 0.05). Particularly, pearson's partial correlation analysis restricted to eyes with NAION revealed stronger correlations between peripapillary RNFL measurements, VD and VR-QoL.

Conclusion

NAION at the acute stage affects VR-QoL in Chinese individuals. Some peripapillary RNFL measurements and VD correlated with VR-QoL. Retinal anatomic and blood flow examinations and inventions in patients with NAION are necessary to facilitate VR-QoL and disease control.

The NEI VFQ-25C: Calibrating Items in the National Eye Institute Visual Function Questionnaire-25 to Enable Comparison of Outcome Measures

Purpose

To improve the usefulness of the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) by enabling estimation of measures on an invariant scale and comparisons between patients and across studies.

Methods

Datasets of baseline NEI VFQ-25 responses from nine studies (seven retina randomized trials, n = 2770; two low vision studies, n = 572) were combined. The method of successive dichotomizations was applied to patient ratings of the main NEI VFQ-25 and six supplemental items to estimate Rasch model parameters using the R package 'msd.' Calibrated item measures and rating category thresholds were estimated for the NEI VFQ-25, as well as for two domain-specific versions: the NEI VFQ-VF that includes only visual function items and the NEI VFQ-SE that includes only socioemotional items.

Results

Calibrated item measures were estimated from study participants (n = 3342) ranging in age from 19 to 103 years, with mean (SD) age of 69.3 (11) years and a mean logMAR visual acuity of 0.30 (Snellen 20/40). Item measure estimates had high precision (standard error range, 0.026-0.085 logit), but person measure estimates had lower precision (standard error range, 0.108-0.499 logit). Items were well targeted to most persons, but not to those with higher levels of function.

Conclusions

Calibrated item measures and rating category thresholds enable researchers and clinicians to estimate visual, socioemotional, and combined measures on an invariant scale using the NEI VFQ-25.

Translational Relevance

Applying NEI VFQ 25C calibrated item measures (software provided) to the NEI VFQ-25, users can estimate overall, visual, and socioemotional function measures for individual patients.

Sociodemographic predictors associated with the spectrum of non-opportunist neuroretinal disease of non-infectious etiology in patients with HIV/AIDS: A scoping review

BACKGROUND

Non-infectious retinal disease, even in the HAART era, continues to be one of the most common diagnoses in patients with HIV, with prevalences of up to 27% of cases. This study aims to characterize the association between demographic variables and their role. As a risk factor for the development of non-opportunistic non-infectious retinal disease in patients with HIV/AIDS.

METHODS

An integrative review of the literature was carried out according to Arksey O'Malley's approach, based on the PICO methodology and following the PRISMA recommendations; An exhaustive search was carried out in databases of articles that were filtered using established criteria, with their extraction and analysis carried out qualitatively.

RESULTS

Ocular manifestations from any cause develop from 35 years of age in patients with HIV/AIDS, with the highest risk for age-related macular degeneration over the fourth decade of life and for the development of neuroretinal disorder on the fifth decade of life; some studies report a slight tendency to diagnose macular degeneration in women and those who acquired AIDS through sexual contact; data contrasted with increased risk for diagnosing neuroretinal disorder in homosexual men who also use intravenous drugs, possibly due to oversampling in studies; non-Hispanic whites and African Americans were the races most commonly affected by neuroretinal disease; the means between the 11.3-14.5 years elapsed since the HIV diagnosis were more frequently associated with cognitive impairment and both in those with high or low CD4 counts, and in patients with high or low viral loads, neuroretinal disease without Statistically significant differences. Adherence and early initiation of HAART had a modest impact on the development of neuroretinal disease.

DISCUSSION

Even in the HAART era, non-infectious neuroretinal disease and cytomegalovirus retinitis remain the most frequent ocular diagnoses, however, different studies argue an increase in age-related non-infectious retinal diseases in patients with HIV, theories that are may explain by the increase in life expectancy, the metabolic effects of HAART itself or the generalized pro-inflammatory state in this group of patients, it is essential to recognize this new diagnostic challenge in order to direct preventive efforts through the use of cost-effective sociodemographic risk predictors towards that technological tools for diagnosis and treatment can be targeted.

CONCLUSIONS

HIV/AIDS patients who present at the ophthalmological consultation with the suggested sociodemographic predictors have a high risk of visual impairment due to non-infectious retinopathy, therefore prevention, diagnosis and treatment efforts directed at these diseases should be increased.

Prevalence and Consequences of Perceived Vision Difficulty in Aging Adults with HIV Infection

PURPOSE

Despite well-known ocular complications of HIV-related immune suppression, few studies have examined the prevalence and consequences of visual impairment among aging long-term survivors of HIV.

DESIGN

Retrospective cohort study.

METHODS

Aging HIV-infected (HIV+) men who have sex with men (MSM) and HIV-uninfected (HIV-) MSM controls reported their difficulty performing 6 vision-dependent tasks (difficulty defined as: no, a little, moderate, and extreme difficulty). Relationships were examined using logistic regression, regressing each outcome separately on categorical visual function responses, with missing data multiply imputed.

RESULTS

There were 634 age-matched pairs for a total sample of 1,268 MSM of 1,700 MSM with available data. The median age was 60 years old (interquartile range [IQR], 54, 66), and 23% were African American. Among HIV+ men, 95% were virally suppressed (viral load <400 copies/mL). HIV+ men were more likely to report moderate or extreme difficulty performing at least 1 task (21% for HIV+ compared to 13% for HIV-; P < .01). Participants reporting extreme vision-related difficulty performing at least 1 task had 11.2 times the odds of frailty (95% confidence interval [CI], 5.2-23.9), 2.6 times the odds of a slow gait speed (95% CI, 1.4-4.8), and 3.2 times the odds of impaired instrumental activities of daily living (95% CI: 1.6-6.3) compared to those reporting no vision-related difficulty on any task.

CONCLUSIONS

Perceived vision difficulty was more common among older HIV+ MSM than age-matched HIV- MSM controls and was associated with higher risk of depression and physical function loss among MSM.

The Changing Global Epidemic of HIV and Ocular Disease

Purpose: Overview of the evolving epidemiology of human immunodeficiency virus (HIV)-related ocular disease over time. Method: Narrative review. Results: HIV enhances susceptibility to opportunistic eye infections, has direct pathogenic effects, and places patients at risk of immune recovery inflammatory syndromes in previously infected eyes after starting highly-active antiretroviral therapy (HAART). Widespread availability of HAART has resulted in a decrease of infectious ocular conditions such as cytomegalovirus retinitis, toxoplasmic retinitis, squamous cell carcinoma of the conjunctiva, and microvascular retinopathy. However, large coexisting burdens of tuberculosis, herpesvirus infection and syphilis (among others) continue to contribute to the burden of ocular disease, especially in low-resource settings. Growing risks of cataract, retinopathy and retinal nerve fiber thinning can affect patients with chronic HIV on HAART; thought due to chronic inflammation and immune activation. Conclusion: The changing epidemic of ocular disease in HIV-infected patients warrants close monitoring and identification of interventions that can help reduce the imminent burden of disease.

Effect of chronic disease self-management program on the quality of life of HIV-infected men who have sex with men: An empirical study in Shanghai, China

OBJECTIVES

The HIV/AIDS epidemic rages on in China, particularly among men who have sex with men (MSM). MSM with HIV/AIDS also tend to have poorer quality of life than other members of the population. A major contributor to these issues is the huge gap between the increasing demand of MSM for medical services and the availability of such services; their current needs cannot be met only with the services of the Chinese Center for Disease Control and Prevention. The aim of the present study was to examine the quality of life of MSM with HIV/AIDS in Shanghai, as well as determine whether it is influenced by chronic disease self-management (CDSM).

METHODS

We conducted a pre-post study to evaluate the effect of CDSM on participants' quality of life. Four hundred twenty participants were assigned to either the CDSM group (n = 210) or the control group (n = 210). We collected data on quality of life (using the Medical Outcomes Study HIV Health Survey [MOS-HIV]) and various psychological and behavioral variables via interviewer-administered questionnaires.

RESULTS

The physical and mental health summary scores of the MOS-HIV were 53.7 and 49.9, respectively. The CDSM group showed a significant improvement in quality of life and a significant decrease in the proportion of participants with anxiety symptoms (from 38.6% to 22.6%). Furthermore, the frequency of condom use increased from 43.3% to 47.3%.

CONCLUSION

MSM with HIV generally had low quality of life in Shanghai. The CDSM program might help promote the quality of life of MSM while helping them practice healthy behaviors.

Geriatric Syndromes in People Living with HIV Associated with Ageing and Increasing Comorbidities: Implications for Neurocognitive Complications of HIV Infection

Long-term survival of treated people living with HIV (PLWH) currently approaches that of the general population. The average age of PLWH is currently in the mid-50s in resource-rich countries and is predicted that over 40% of PLWH will be older than 60 within a decade. Similar trends have been confirmed in all communities of PLWH with access to antiretroviral therapies. However, the positive impact on survival has been challenged by several developments. Ageing PLWH have clinical features similar to the general population about 5-10 years older. In addition to the earlier occurrence of common age-related conditions common geriatric syndromes have also impacted this population prematurely. These are often difficult to evaluate and manage conditions usually of multifactorial aetiology. They include polypharmacy, frailty, impaired mobility and falls, sarcopenia, sensory impairment, and increasingly, non-dementing cognitive decline. Cognitive decline is of particular concern to PLWH and their care providers. In the general geriatric population cognitive impairment increases with age and occurs in all populations with a prevalence of over 25% in people over 80. Effective treatments are lacking and therefore minimizing risk factors plays an important role in maintaining healthspan. In the general population geriatric syndromes may increase the risk of cognitive decline. The corollary is that decreasing the risk of their development may limit cognitive impairment. Whether a similar status holds in PLWH is uncertain. This chapter will address the question of whether common geriatric syndromes in PLWH contribute to cognitive impairment. Common risk factors may provide clues to limit or delay cognitive decline.

Ophthalmologic Disease in HIV Infection: Recent Changes in Pathophysiology and Treatment

PURPOSE OF REVIEW

Ophthalmologic conditions were among the earliest described findings in patients with the acquired immunodeficiency syndrome (AIDS). The purpose of this review is to highlight recent changes in the pathophysiology and management of ophthalmologic conditions in patients infected with the human immunodeficiency virus (HIV).

RECENT FINDINGS

The introduction of highly active antiretroviral therapy (HAART) in 1996 changed ophthalmologic findings from predominantly acute infectious diseases to chronic, slowly progressive, debilitating conditions. HIV-associated neuroretinal disorder infrequently leads to blindness, but it causes visual disability in a large percentage of patients. Cytomegalovirus retinitis is now seen less commonly in the USA, but it remains an important cause of blindness in HIV-infected patients from developing countries. Immune recovery uveitis has emerged as a major cause of visual disability in the USA. As HIV has become a chronic disease, visual disability due to chronic noninfectious diseases have become increasingly important.
