Background/AimsDiabetic retinopathy (DR) is associated and shares many risk factors with other diabetic complications, including inflammation. Bacterial infections, potent inducers of inflammation have been associated with the development of diabetic complications apart from DR. Our aim was to investigate the association between bacterial infections and DR.MethodsAdult individuals with type 1 diabetes (n=1043) were recruited from the Finnish Diabetic Nephropathy Study (FinnDiane), a prospective follow-up study. DR was defined as incident severe diabetic retinopathy (SDR), identified as first laser treatment. Data on DR were obtained through fundus photographs and medical records, data on bacterial infections from comprehensive national registries (1 January 1995 to 31 December 2015). Risk factors for DR and serum bacterial lipopolysaccharide (LPS) activity were determined at baseline.ResultsIndividuals with incident SDR (n=413) had a higher mean number of antibiotic purchases/follow-up year compared with individuals without incident SDR (n=630) (0.92 [95% CI 0.82 to 1.02] vs 0.67 [0.62–0.73], p=0.02), as well as higher levels of LPS activity (0.61 [0.58–0.65] vs 0.56 [0.54–0.59] EU/mL, p=0.03). Individuals with on average ≥1 purchase per follow-up year (n=269) had 1.5 times higher cumulative incidence of SDR, compared with individuals with <1 purchase (n=774) per follow-up year (52% vs 35%, p<0.001). In multivariable Cox survival models, the mean number of antibiotic purchases per follow-up year as well as LPS activity were risk factors for SDR after adjusting for static confounders (HR 1.16 [1.05–1.27], p=0.002 and HR 2.77 [1.92–3.99], p<0.001, respectively).ConclusionBacterial infections are associated with an increased risk of incident SDR in type 1 diabetes.

<b>Objective:</b> We hypothesized that there is heterogeneity in long-term patterns of glycemic control with respect to cardiovascular disease (CVD) development in type 1 diabetes and that risk factors for CVD differ by glycemic control pattern. Thus, we estimated associations between data-derived latent HbA1c trajectories and 30-year CVD risk in the Pittsburgh Epidemiology of Diabetes Complications (EDC) study of childhood-onset (<17 years old) type 1 diabetes.<b> </b> <p><b>Research Design and Methods: </b>Participants (n=536 with ≥2 HbA1c measurements [median 6] and CVD-free at baseline; mean age 27 and diabetes duration 18 years) were followed from 1986-88 to 2016-18 to ascertain CVD incidence (CVD death, myocardial infarction, stroke, coronary revascularization or blockage ≥50%, ischemic ECG, or angina). Latent HbA1c trajectories and their association with time-to-CVD incidence were simultaneously assessed using Joint Latent Class Mixed Models.</p> <p><b>Results:</b> Two HbA1c trajectories with respect to differential CVD risk were identified: Low (HbA1c ~8% [64 mmol/mol] and improving over follow-up, 76% of cohort) and High (HbA1c ~10% [86 mmol/mol] and stable, 24%). Overall, 30-year CVD incidence was 47.4% (n=253); MACE incidence 31.0% (n=176). High HbA1c was associated with 3-fold increased CVD risk versus Low HbA1c. Both groups had similar age and diabetes duration. Non-HDLc and estimated glomerular filtration rate were associated with CVD risk only in Low HbA1c; albumin excretion rate was associated with CVD risk only in High HbA1c.<b> </b></p> <p><b>Conclusions: </b>These risk factor differences suggest that pathways to CVD may differ by glycemic control, potentially resulting in important implications for prognosis in type 1 diabetes.</p>

The long-term complications of diabetes mellitus include retinopathy, nephropathy, and neuropathy. Diabetic retinopathy can result in loss of vision; nephropathy may lead to end-stage kidney disease (ESKD); and neuropathy poses the risk of foot ulcers, amputation, Charcot joints, sexual dysfunction, and potentially disabling dysfunction of the stomach, bowel, and bladder. Hyperglycemia sufficient to cause pathologic and functional changes in target tissues may be present for some time before clinical symptoms lead to a diagnosis of diabetes, especially in patients with type 2 diabetes. Diabetic patients are also at increased risk for atherosclerotic cardiovascular, peripheral vascular, and cerebrovascular disease. These conditions may be related to hyperglycemia, as well as to the hypertension and abnormal lipoprotein profiles that are often found in diabetic patients. Prevention of these complications is a major goal of current therapeutic policy and recommendations for all but transient forms of diabetes. This chapter describes the pathogenesis, screening, prevention, and treatment of diabetic complications, as well as the management of hyperglycemia in the hospitalized patient. Figures illustrate the pathways that link high blood glucose levels to microvascular and macrovascular complications; fundus abnormalities in diabetic retinopathy; the natural history of nephropathy in type 1 diabetes; cumulative incidence of first cardiovascular events, stroke, or death from cardiovascular disease in patients with type 1 diabetes; the effect of intensive glycemic therapy on the risk of myocardial infarction, major cardiovascular event, or cardiovascular death in patients with type 2 diabetes; and risk of death in patients with type 2 diabetes who receive intensive therapy of multiple risk factors or conventional therapy. Tables describe screening schedules for diabetic complications in adults, foot care recommendations for patients with diabetes, and comparison of major trials of intensive glucose control. This chapter has 238 references.
