The patients were followed for an average of years. Subjects were instructed to report all episodes of suspected severe hypoglycemia to their health care team. General Description. The Diabetes Control and Complications Trial DCCT was a multicenter, randomized clinical trial designed to compare intensive with conventional diabetes therapy with regard to their effects on the development and progression of the early vascular and neurologic complications of type 1 insulin-dependent diabetes mellitus.

This advance, along with A1C testing and insulin pump therapy, made possible the Diabetes Control and Complications Trial, which positively answered the long debate about the relationship between glucose control and diabetes complications 2.

Furthermore, the relative benefits of intensive therapy on all complications were greater in the primary Author: Son Pham, T. Phuong-Thu, Robert Chilton. Background: Long-term microvascular and neurologic complications cause major morbidity and mortality in patients with insulin-dependent diabetes mellitus IDDM.

We examined whether intensive treatment with the goal of maintaining blood glucose concentrations close to the normal range could decrease the frequency and severity of these complications. Objective: The Diabetes Control and Complications Trial DCCT demonstrated the powerful impact of glycemic control on the early manifestations of microvascular complications. Contemporary prospective data on the evolution of macrovascular and late microvascular complications of type 1 diabetes.

The Diabetes Control and Complications Trial DCCT did not show a significant reduction in cardiovascular events with intensive control in young patients with type 1 diabetes, 2 but a follow-up Cited by: The NIDDK funded the landmark Diabetes Control and Complications Trial DCCT to see if people with type 1 diabetes who kept their blood glucose levels as close to normal as safely possible with intensive diabetes treatment three or more shots of insulin per day or an insulin pump with self-monitoring of blood glucose at least four times per day could slow the development of eye, kidney,.

Type 2 diabetes mellitus is a growing pandemic and a leading cause of morbidity and mortality. In terms of glycemic control, landmark RCTs have demonstrated that meticulous glycemic control reduces risk of microvascular and neurological complications of chasyveka.

Early Worsening of Diabetic Retinopathy in the Diabetes Control and Complications Trial

The DCCT — was a controlled clinical trial in 1, subjects with T1DM comparing intensive therapy INT , aimed at achieving levels of glycemia as close to the nondiabetic range as safely possible, with conventional therapy CON , which aimed to maintain safe asymptomatic glucose control. INT utilized three or more daily insulin injections or insulin pump therapy guided by self-monitored glucose. The major adverse effect of INT was a threefold increased risk of hypoglycemia, which was not associated with a decline in cognitive function or quality of life. EDIC showed a durable effect of initial assigned therapies despite a loss of the glycemic separation metabolic memory and demonstrated that the reduction in early-stage complications during the DCCT translated into substantial reductions in severe complications and CVD. The plight of people with type 1 diabetes changed dramatically with the introduction of insulin therapy in 1. Type 1 diabetes was transformed from a uniformly fatal disease in the preinsulin era, with mortality occurring either acutely from diabetic ketoacidosis or subsequently from inanition owing to a chronic catabolic state, to a chronic degenerative disease. In the first 15 to 20 years of insulin therapy, a host of complications that had never been seen before was discovered in people with long-term diabetes 2.

The Epidemiology of Diabetes Interventions and Complications study EDIC observational follow-up showed that the risk of further progression of retinopathy 4 years after the DCCT ended was also greatly reduced in the former intensive group, despite nearly equivalent levels of HbA 1c , a phenomenon termed metabolic memory. Metabolic memory was shown to persist through 10 years of follow-up. We now describe the risk of further progression of retinopathy, progression to proliferative diabetic retinopathy, clinically significant macular edema, and the need for intervention photocoagulation or anti-VEGF over 18 years of follow-up in EDIC. The cumulative incidence of each retinal outcome continues to be lower in the former intensive group. However, the year-to-year incidence of these outcomes is now similar, owing in large part to a reduction in risk in the former conventional treatment group.

Long-term microvascular and neurologic complications cause major morbidity and mortality in patients with insulin-dependent diabetes mellitus IDDM. We examined whether intensive treatment with the goal of maintaining blood glucose concentrations close to the normal range could decrease the frequency and severity of these complications. A total of patients with IDDM -- with no retinopathy at base line the primary-prevention cohort and with mild retinopathy the secondary-intervention cohort were randomly assigned to intensive therapy administered either with an external insulin pump or by three or more daily insulin injections and guided by frequent blood glucose monitoring or to conventional therapy with one or two daily insulin injections.

In , the investigators reported that intensive glycemic treatment of patients with type 1 diabetes mellitus was superior to conventional therapy in preventing the development of microvascular and neurological complications and thus provided definitive proof of the relationship between hyperglycemia and the subsequent risk of diabetic retinopathy, nephropathy and neuropathy. The value of this study, however, did not end there. After the original trial, most participants of the DCCT continued to be followed up in the Epidemiology of Diabetes Interventions and Complications EDIC study, which demonstrated the long-term benefits of close glycemic control and provided observational data of a large epidemiological cohort of patients with type 1 diabetes mellitus.


The Diabetes Control and Complications Trial/Epidemiology of Diabetes Inter- ventions and Complications (DCCT/EDIC) study continues to address knowledge​.


In patients with T1DM, how does strict glycemic control with intensive therapy compare with conventional therapy in preventing microvascular complications? The Diabetes Control and Complications Trial DCCT demonstrated that strict glycemic control targeting lower HbA1c goals among patients with T1DM can both delay the onset of retinopathy, nephropathy, and neuropathy and slow the progression of existing microvascular complications. This came at the expense of a threefold higher risk of hypoglycemia, underlying the fact that HbA1c goals should be tailored to the individual. DCCT was unable to demonstrate a reduction in CV events, likely because the study population was relatively young at the time. However, EDIC and other follow-up studies did demonstrate such benefits.
