Abstract
Purpose Diabetic macular edema (DME), a leading cause of visual impairment, can occur regardless of diabetic retinopathy (DR) stage. Poor metabolic control is hypothesized to contribute to DME development, although large-scale studies have yet to identify such an association. This study aims to determine whether measurable markers of dysmetabolism are associated with DME development in persons with diabetes. Design Retrospective cohort study. Participants Using data from the Sight Outcomes Research Collaborative (SOURCE) repository, patients with diabetes mellitus and no preexisting DME were identified and followed over time to see what factors associated with DME development. Methods Cox proportional hazard modeling was used to assess the relationship between demographic variables, diabetes type, smoking history, baseline DR status, blood pressure (BP), lipid profile, body mass index (BMI), hemoglobin A1C (HbA1C), and new onset of DME. Main Outcome Measures Adjusted hazard ratio (HR) of developing DME with 95% confidence intervals (CIs). Results Of 47 509 eligible patients from 10 SOURCE sites (mean age 63 ± 12 years, 58% female sex, 48% White race), 3633 (7.6%) developed DME in the study period. The mean ± standard deviation time to DME was 875 ± 684 days (∼2.4 years) with those with baseline nonproliferative DR (HR 3.67, 95% CI: 3.41-3.95) and proliferative DR (HR 5.19, 95% CI: 4.61-5.85) more likely to develop DME. There was no difference in DME risk between type 1 and type 2 patients; however, Black race was associated with a 40% increase in DME risk (HR 1.40, 95% CI: 1.30-1.51). Every 1 unit increase in HbA1C had a 15% increased risk of DME (HR 1.15, 95% CI: 1.13-1.17), and each 10 mmHg increase in systolic BP was associated with a 6% increased DME risk (HR 1.06, 95% CI: 1.02-1.09). No association was identified between DME development and BMI, triglyceride levels, or high-density lipoprotein levels. Conclusions These findings suggest that in patients with diabetes modifiable risk factors such as elevated HbA1C and BP confer a higher risk of DME development; however, other modifiable systemic markers of dysmetabolism such as obesity and dyslipidemia did not. Further work is needed to identify the underlying contributions of race in DME.

[PMID: 38827773 PMCID: PMC11141735 DOI: 10.2147/opth.s463624] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Accepted: 05/09/2024] [Indexed: 06/05/2024] Open
Abstract
Purpose The purpose of this study was to assess preliminary real-world outcomes in neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME) treated with intravitreal faricimab. Patients and Methods This was a retrospective, observational consecutive-case real-world study of patients with nAMD or DME initiated on intravitreal faricimab between November 2022 and April 2023. Treatment-naïve patients and patients previously treated with alternate anti-vascular endothelial growth factor (anti-VEGF) agents were initiated on an intended treatment plan of four monthly faricimab injections as a loading regime. Efficacy was assessed across four treatment groups. Primary outcomes assessed for both cohorts were changes in best corrected visual acuity (BCVA) and central subfield thickness (CST) on optical coherence tomography (OCT). Secondary outcomes were alterations in OCT-defined structural features. Results From 127 patients, 146 eyes received at least one dose of faricimab. Mean BCVA, measured in Early Treatment of Diabetic Retinopathy Study (ETDRS) letters, from baseline to fifth visit increased from: 59.0±12.8 to 62.2±14.3 in treatment-naïve nAMD; 61.1±17.6 to 63.5±14.8 in previously-treated nAMD; 61.1±13.0 to 72.8±11.5 in treatment-naïve DME; and 60.8±14.6 to 63.3±15.6 in previously-treated DME. Mean CST reduced in all four treatment groups between initiation to final loading dose, from: 442.8±172.0µm to 305.2±117.0µm (p<0.0001) in treatment-naïve nAMD; 355.2±115.1µm to 297.9±92.54µm (p<0.0001) in previously-treated nAMD; 465.8±109.1µm to 343.1±100.3µm (p<0.0001) in treatment-naïve DME; and 492.5±133.1µm to 388.5±131.4µm (p<0.0001) in previously-treated DME. Conclusion Real-world outcomes showed some improvement in BCVA and CST for nAMD and DME following faricimab administration, including in patients previously treated with other anti-VEGF agents. Further work involving larger cohorts over longer periods is required to determine whether improvement is maintained, and if intervals can be extended to match those observed in clinical trials.

Rationale and Design of VOYAGER: Long-term Outcomes of Faricimab and Port Delivery System with Ranibizumab for Neovascular Age-Related Macular Degeneration and Diabetic Macular Edema in Clinical Practice. OPHTHALMOLOGY SCIENCE 2024; 4:100442. [PMID: 38304609 PMCID: PMC10831184 DOI: 10.1016/j.xops.2023.100442] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 11/27/2023] [Accepted: 11/28/2023] [Indexed: 02/03/2024]
Abstract
Purpose To describe the rationale and design of the VOYAGER (NCT05476926) study, which aims to investigate the safety and effectiveness of faricimab and the Port Delivery System with ranibizumab (PDS) for neovascular age-related macular degeneration (nAMD) or diabetic macular edema (DME) in clinical practice. VOYAGER also aims to understand drivers of clinical practice treatment outcomes by gaining novel insight into the intersection of treatment regimens, decisions, anatomic outcomes, and vision. Design Primary data collection, noninterventional, prospective, multinational, multicenter clinical practice study. Participants At least 5000 patients initiating/continuing faricimab or PDS for nAMD/DME (500 sites, 31 countries). Methods Management will be per usual care, with no mandated scheduled visits/imaging protocol requirements. Using robust methodologies, relevant clinical and ophthalmic data, including visual acuity (VA), and data on treatment clinical setting/regimens/philosophies, presence of anatomic features, and safety events will be collected. Routinely collected fundus images will be uploaded to the proprietary Imaging Platform for analysis. An innovative investigator interface will graphically display the patient treatment journey with the aim of optimizing treatment decisions. Main Outcome Measures Primary end point: VA change from baseline at 12 months per study cohort (faricimab in nAMD and in DME, PDS in nAMD). Secondary end points: VA change over time and per treatment regimens (fixed, treat-and-extend, pro re nata, and other) and number. Exploratory end points: VA change in relation to presence/location of anatomic features that impact vision (fluid, central subfield thickness, fibrosis, atrophy, subretinal hyperreflective material, diabetic retinopathy severity, and disorganization of retinal inner layers) and per treatment regimen/philosophies. The impact of regional and practice differences on outcomes will be assessed as will safety. Results Recruitment commenced in November 2022 and will continue until late 2027, allowing for up to 5 years follow-up. Exploratory interim analyses are planned annually. Conclusions VOYAGER is an innovative study of retinal diseases that will assess the effectiveness and safety of faricimab and PDS in nAMD and DME and identify clinician- and disease-related factors driving treatment outcomes in clinical practices globally to help optimize vision outcomes.

Impact of socioeconomic status on chronic control and complications of type 1 diabetes mellitus in users of glucose flash systems: a follow-up study. BMC Med 2024; 22:37. [PMID: 38273326 PMCID: PMC10809494 DOI: 10.1186/s12916-024-03254-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 01/10/2024] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND This study investigates the association between socioeconomic status (SES) and glycemic control in individuals with type 1 diabetes (T1D) using flash glucose monitoring (FGM) devices within a public health system where these technologies are freely available and utilized according to recommended guidelines. METHODS A follow-up study of 1060 adults (mean age 47.4 ± 15.0 years, 49.0% women) with T1D, receiving care at three Spanish university hospitals that regularly employ the FGM system. SES was assessed using the Spanish Deprivation Index and the average annual net income per person. Glycemic data were collected over a 14-day follow-up period, including baseline glycated hemoglobin (HbA1c) levels prior to sensor placement, the last available HbA1c levels, and FGM-derived glucose metrics. Individuals with sensor usage time < 70% were excluded. Chronic micro and macrovascular complications related to diabetes were documented. Regression models, adjusted for clinical variables, were employed to determine the impact of SES on optimal sensor control (defined as time in range (TIR) ≥ 70% with time below range < 4%) and disease complications. RESULTS The average follow-up was of 2 years. The mean TIR and the percentage of individuals with optimal control were higher in individuals in the highest SES quartile (64.9% ± 17.8% and 27.9%, respectively) compared to those in the lowest SES quartile (57.8 ± 17.4% and 12.1%) (p < 0.001). Regression models showed a higher risk of suboptimal control (OR 2.27, p < 0.001) and ischemic heart disease and/or stroke (OR 3.59, p = 0.005) in the lowest SES quartile. No association was observed between SES and the risk of diabetic nephropathy and retinopathy. FGM system improved HbA1c levels across all SES quartiles. Although individuals in the highest SES quartile still achieved a significantly lower value at the end of the follow-up 55 mmol/mol (7.2%) compared to those in the lowest SES quartile 60 mmol/mol (7.6%) (p < 0.001), the significant disparities in this parameter between the various SES groups were significantly reduced after FGM technology use. CONCLUSIONS Socioeconomic status plays a significant role in glycemic control and complications in individuals with T1D, extending beyond access to technology and its proper utilization. The free utilization of FGM technology helps alleviate the impact of social inequalities on glycemic control.

Abstract
Importance Deficient ophthalmologic care is costly to patients, making the identification of groups not receiving adequate care of vital importance. The current landscape of equity in ophthalmic care has yet to be thoroughly investigated and is important to ensure inclusivity and patient-centered care. Objective To perform a scoping review of the literature pertaining to health care inequities in the field of ophthalmology. Evidence Review A comprehensive database search using MEDLINE (via PubMed) and Ovid Embase was done in July 2022. English-language articles published from 2016 to 2021 were included and encompassed all article types except commentaries or correspondence. The search modeled the National Institutes of Health list of designated US health inequity populations, which includes income, education level, occupational status, rural and underresourced area, sex and gender, lesbian, gay, bisexual, transgender, and queer (LGBTQ) identity, and race and ethnicity. A total of 8170 abstracts and titles were screened by 2 independent investigators, and 189 studies were assessed in full text for eligibility. For inclusion, articles needed to be an ophthalmic study discussing health inequities. In a masked, duplicate fashion, 2 independent investigators screened 75 full-text studies for data extraction using a pilot-tested form. Data extraction included general publication characteristics and health inequity data based on the National Institutes of Health's defined inequity groups. Findings A total of 75 publications were included. Notable inequities were found among Black and Hispanic patients associated with negative ophthalmic outcomes and mixed associations regarding sex or gender. Overall, lower-income patients were more likely to have vision impairment, use eye care services less, and have lower adherence to eye examinations. No articles within our sample examined LGBTQ inequities among ophthalmology patients since the 2016 National Institutes of Health classification of sexual and gender minority populations. Substantial research gaps were observed within the ophthalmic literature pertaining to the LGBTQ community, race and ethnicity, and rural and underresourced areas. Conclusions and Relevance This scoping review found substantial findings associated with the LGBTQ community, race and ethnicity, and the role of telemedicine in rural and underresourced areas. Because of the importance of ophthalmic care in overall patient health, it is vital to understand the various inequities present and strive to improve the current gaps in the literature. Future studies should (1) examine barriers to clinical study and medical trainee recruitment as well as patient values and preference studies and (2) investigate the implementation of telemedicine in underresourced areas.

Abstract
Diabetic retinal disease (DRD) is the leading cause of blindness among working-aged individuals with diabetes. In the United States, underserved and minority populations are disproportionately affected by diabetic retinopathy and other diabetes-related health outcomes. In this narrative review, we describe racial disparities in the prevalence and screening of diabetic retinopathy, as well as the wide-range of disparities associated with social determinants of health (SDOH), which include socioeconomic status, geography, health-care access, and education.
