Association Between Perceived Barriers to Diabetes Self-management and Diabetic Retinopathy in Asian Patients With Type 2 Diabetes.

ABSTRACT: Importance:A patient’s perceived barriers to diabetes self-management (DSM) may affect his or her risk of diabetic retinopathy (DR); however, few studies have examined this association. Objective:To examine the association between perceived barriers to DSM and the severity spectrum of DR in Asian patients with type 2 diabetes. Design, Setting, and Participants:A cross-sectional clinic-based study, the Singapore Diabetes Management Project, was conducted from December 28, 2010, to March 20, 2013, at the Singapore National Eye Centre, a tertiary eye care institute. After excluding patients with type 1 diabetes and ungradable fundus images, 361 participants were included in the analyses. Statistical analysis was conducted from July 20 to September 8, 2017. Exposure:The degree of perceived barriers to DSM was assessed using a 23-item questionnaire comprising items about knowledge of DSM, access to care, and confidence in health care professionals. Rasch analysis was used to optimize the scale’s psychometric properties, with lower scores indicating a higher degree of self-perceived barriers. Main Outcomes and Measures:Diabetic retinopathy was graded from 2-field retinal images into categories of no DR (Early Treatment Diabetic Retinopathy Study levels 10-15; n?=?154), mild to moderate DR (levels 20-43; n?=?112), and severe DR (levels ?53 and/or presence of clinically significant macular edema; n?=?95) using the modified Airlie House classification system of DR. Multinomial logistic regression models were used to assess the association between perceived barriers and severity of DR in the worse-affected eye. Results:Among the 361 participants (105 women and 256 men; mean [SD] age, 57 [8] years), a greater magnitude of perceived barriers to DSM was independently associated with higher odds of having any DR (odds ratio, 1.32; 95% CI, 1.06-1.66), mild to moderate DR (odds ratio, 1.30; 95% CI, 1.01-1.68), and severe DR (odds ratio, 1.36; 95% CI, 1.03-1.79). This association was independent of diabetes control (hemoglobin A1c, blood pressure, and lipid levels), presenting visual acuity, and socioeconomic indicators. Conclusions and Relevance:These results suggest that greater perceived barriers to DSM are independently associated with severity of DR. Although longitudinal data are needed, these findings suggest that evidence-based interventions to reduce patient-, practitioner-, and system-related barriers to diabetes care may help reduce the risk of DR.

Project description:Importance:The comorbidity of chronic kidney disease and diabetic retinopathy (DR) is well known. However, to our knowledge, no cohort study has demonstrated the effect of chronic kidney disease on the development or progression of DR. Objective:To investigate the association of chronic kidney disease with the development of DR and diabetic macular edema (DME) in type 2 diabetes. Design, Setting, and Participants:This 8-year prospective cohort study that was conducted in 2 medical centers in Taiwan included 2135 patients with type 2 diabetes. Exposures:The baseline and mean follow-up renal profiles including serum creatinine level, estimated glomerular filtration rate (eGFR), and urinary albumin/creatinine ratio (ACR). Main Outcomes and Measures:Diabetic retinopathy and DME were detected with nonmydriatic fundus photography. Cox regression analyses was used to evaluate the hazard ratios (HRs) for the renal profiles of new-onset DR, proliferative DR, and DME. Results:The mean (SD) age of the study participants was 63.4 (11.9) years and 1025 (48%) were women. A higher serum creatinine level (HR of 2.358 for an increase of 1 mg/dL [to convert to micromoles per liter, multiply by 76.25]; 95% CI, 1.901-2.924; P < .001), an estimated glomerular filtration rate of less than 60 mL/min/1.73m2 (40-60: HR, 2.235; 95% CI, 1.351-4.035; P = .002; 30-45: HR, 2.625; 95% CI, 1.436-4.798; P = .002; <30: HR, 5.488; 95% CI, 2.739-10.993; P < .001), and a urinary albumin to creatinine ratio (ACR) of more than 30 mg/g (31-300: HR, 3.202; 95% CI, 2.029-5.053; P < .001; >300: HR, 6.652; 95% CI, 3.922-11.285; P < .001) at baseline were all associated with the development of proliferative DR. A baseline urinary ACR of more than 30 mg/g (31-300: HR, 1.563; 95% CI, 1.078-2.267; P = .02; >300: HR, 2.707; 95% CI, 1.640-4.470; -2.707; P < 0.001) was associated with the development of DME. After adjusting the baseline values, the mean follow-up renal profiles, including a higher serum creatinine level (HR, 2.369 per mg/dL; 95% CI, 1.704-3.293; P < .001), an estimated glomerular filtration rate of less than 30 mL/min/1.73m2 (HR, 4.215; 95% CI, 1.265-14.039; P = .02), and a urinary ACR of more than 30 mg/g (31-300: HR, 2.344; 95% CI, 1.200-4.503; P = .01; >300: HR, 4.193; 95% CI, 1.638-10.735; P = .003) were still correlated with new-onset PDR during the follow-up periods. Conclusions and Relevance:Abnormal renal profiles at baseline, including a high serum creatinine level, low estimated glomerular filtration rate, and high urinary ACR, were associated with the development of PDR in patients with type 2 diabetes. A high baseline urinary ACR was associated with DME. Abnormal mean follow-up renal profiles were still correlated with new-onset PDR after adjusting for baseline values. Aggressive treatment for chronic kidney disease may have a role in preventing the deterioration of DR.

Project description:AIM:To investigate the association between a set of six candidate genes and the risk of diabetic retinopathy (DR) in an urban community cohort of Chinese patients with type 2 diabetes mellitus (T2DM). METHODS:A population-based cross-sectional study. The diabetic subjects were recruited from an urban community in Beijing and categorized into groups of proliferative diabetic retinopathy (PDR), non-proliferative diabetic retinopathy (NPDR), or diabetic without any retinopathy (DWR) based on the fundus photography and duration of diabetes. Six candidate genes, including advanced glycation end product specific receptor (AGER), aldose reductase (AKR1B1), inducible nitric oxide synthase (iNOS), pigment epithelium derived factor (PEDF), tumor necrosis factor-alpha (TNF-α), and paraoxonase 1 (PON1), were chosen based on Meta-analysis of genetic association studies for DR and biochemical pathways implicated in DR progression. The allele and genotype distribution of 21 functional single-nucleotide polymorphisms (SNPs) in those 6 candidate genes were investigated using MassARRAY genotyping system. RESULTS:Among 1461 diabetic patients recruited from community, 569 were selected in following genotyping analysis, including 97 patients with PDR, 217 with NPDR, and 255 with DWR. For the promoter variant rs1051993 in AGER gene, the distribution of allele and genotype in PDR group differed from that in DWR group (allele: P=0.011; genotype: P=0.01). Compared with DWR, patients with PDR had lower frequencies of heterozygous genotype GT (9.8% for DWR, 1% for PDR, OR: 0.10, 95%CI: 0.01-0.72) and minor allele T (4.9% for DWR, 0.5% for PDR, OR: 0.10, 95%CI: 0.01-0.75). In multivariate model, the distribution of genotype for rs1051993 in PDR group was significantly different from that in DWR group (GT vs GG: OR: 0.07, 95%CI: 0.01-0.61, P<0.001). No association with DR was observed in other genotyped SNPs. CONCLUSION:The data suggest a significant association of the promoter variant rs1051993 in AGER gene with PDR in Chinese cohort with T2DM.
