IMPENDIA- PEN VS Dianeal Only Improved Metabolic Control In Diabetic CAPD and APD Patients

Study Overview
=================
Brief Summary
-----------------
Primary Objective: To demonstrate that use of glucose sparing prescriptions (PEN vs Dianeal) in diabetic (Type 1 and Type 2) Continuous Ambulatory Peritoneal Dialysis (CAPD)and Automated Peritoneal Dialysis (APD) patients leads to improved metabolic control as measured by the magnitude of change from the baseline value in the HbA1c levels. Secondary Objectives: To demonstrate that use of glucose-sparing PD solutions (PEN vs Dianeal) in diabetic (Type 1 and Type 2) CAPD and APD patients leads to lower glycemic-control medication requirements, decreased incidence of severe hypoglycemic events requiring medical intervention, improved metabolic control, nutritional status, and Quality of Life. In a subgroup of patients, the impact of glucose-sparing PD solutions (PEN vs Dianeal only) on abdominal fat and left ventricular (LV) structure and function will be assessed.

Visual analogue scale is the second part of the questionnaire, asking to mark health status on the day of the interview on a 20 cm vertical scale with end points of 0 and 100. There are notes at the both ends of the scale that the bottom rate (0) corresponds to  the worst health you can imagine, and the highest rate (100) corresponds to the best health you can imagine.

| Change From Baseline in QOL Based on the Diabetes Symptom Checklist (DSC) at Month 3 and 6 | The Diabetes Symptoms Checklist was designed to assess the presence and perceived burden of diabetes-related symptoms. Respondents were to consider troublesomeness of 34 symptoms on a 5-point scale ranging from 5=extremely to 1=not at all. For symptoms/side-effects not experienced, the item was scored as 0. Symptoms were grouped into the following subscales: psychological fatigue, psychological cognitive, neurology pain, neurology sensory, cardiology, ophthalmology, hypoglycemia, hyperglycemia. Subscale scores were calculated as the sum of the given subscale divided by the total number of items in the scale. Total score was computed from the sum of the 8 subscales and ranged from 0 to 40. Higher scores indicate greater symptom burden.
