About

The purpose of this study is to compare the progression of kidney disease in subjects with Diabetes mellitus type 2 and Advanced Diabetic Nephropathy treated by routine follow-up as a general care and in subjects treated by multi-factorial intervention in the Diabetes-Renal Clinic.

Full description

In this study, the overall objective is comparison of progression of renal insufficiency in subjects with Advanced Diabetic Nephropathy (CKD stages 3 and 4) randomized into multifactorial intervention in the Diabetes-Renal Clinic (study group) and into usual care (control group). The multifactorial intervention includes the following: 1. Blood pressure control to the goal of <130/80mmHg and renal protection with reduction of proteinuria to <0.5g/day using a protocol that includes therapy with ACE inhibitors, ARBs or their combination. 2. Tight glucose control using SMBG and Lantus/Apidra self-escalation regimen. 3. Use of hypolipidemic therapy to achieve targets of LDL of < 70 mg/dl, HDL > 40/50 mg/dl (males/females) [since you said that HDL is not a target because there are no meds for it I deleted HDL;] and triglycerides of less than 200 mg/dl. 4. Patient enhanced self-management provided by combined diabetes-renal education curriculum (taught by certified diabetes and renal educators). 5. Behavior and social intervention (motivational interviews and social assessment) provided as needed by social workers. 6. Intense case management that includes close follow-up of visits, laboratory monitoring and other self-adherence behaviors. 7. Weight loss with lifestyle and diet modification.

Control Group will keep on receiving the usual treatment that they used to receive from their respective clinics and the Diabetes-Renal team would not alter their therapy or interfere in their management.

Enrollment: 120 patients

Inclusion criteria

1. The participant is male or female diagnosed with Type 2 Diabetes mellitus defined by the American Diabetes Association criteria and must be aged 18 to 70 years.

2. The participant must have documented Advanced Diabetic Nephropathy (ADN) defined as presence of proteinuria or micro/macro-albuminuria and impaired GFR (by MDRD equation) corresponding to Chronic Kidney Disease (CKD) stages 3-4 (moderate-severe i.e. estimated GFR >15ml/min and <60ml/min).

   A. Presence of macroalbuminuria B. Presence of microalbuminuria if no therapy with ACE inhibitors or ARBs C. Presence of current microalbuminuria and previous documentation of macroalbuminuria D. Presence of current microalbuminuria and previous documentation of Diabetic Retinopathy or laser therapy E. If only microalbuminuria and no A, B, C or D US of kidney shows NL size.

3. Minimal cognitive function for a diabetes self management

4. Fasting or random Blood glucose <400mg/DL
