Abstract |
Aim |
This study aimed to determine the association between fenofibrate added to statin therapy and diabetic retinopathy progression.
Methods |
In this propensity-matched study using the Korean National Health Insurance Service cohort (2002-2019), patients with type 2 diabetes and metabolic syndrome (≥ 30 years) receiving statin therapy were matched 1:2 by propensity score into the statin plus fenofibrate group (n=22,395) and statin-only group (n=43,191). The primary outcome was a composite of diabetic retinopathy progression including vitreous hemorrhage, vitrectomy, laser photocoagulation, intravitreous injection therapy and retinal detachment.
Results |
The median (quartiles) follow-up duration was 44.0 (27.6–70.6) months. For the primary outcome, the incidence rate per 1,000 person-years was 9.66 in the statin-only group and 8.68 in the statin-plus-fenofibrate group. The risk of the primary outcome was significantly lower (hazard ratio [HR]=0.88; 95% confidence interval [0.81;0.96] P = 0.005) in the statin-plus-fenofibrate group than in the statin-only group. Only patients with pre-existing retinopathy showed benefits from fenofibrate treatment (HR=0.83 [0.73;0.95] P = 0.006). In addition, the statin plus fenofibrate group exhibited significantly lower risks of vitreous hemorrhage (HR= 0.86 [0.75;0.995] P = 0.042), laser photocoagulation (HR=0.86 [0.77;0.96] P = 0.009) and intravitreous injection therapy (HR=0.73 [0.59;0.90] P = 0.003) than those in the statin-only group. There was no significant interaction between the different characteristics at baseline and the treatment effect.
Conclusion |
The addition of fenofibrate to statins was associated with significantly lower risk of diabetic retinopathy progression than statin therapy alone in patients with type 2 diabetes and metabolic syndrome.
