Effect of Structured Diabetes Education on Diabetic Angiopathies Among Kidney Transplant Recipients With Posttransplant Diabetes: Kuwait Experience

Abstract

Objectives: Diabetes knowledge among kidney transplant recipients with posttransplant diabetes has not been exhaustively assessed. Here, we evaluated the effects of structured diabetes education on development of diabetic micro- and macroangiopathies in kidney transplant patients with posttransplant diabetes.

Materials and methods: This prospective randomized controlled study categorized 210 renal transplant patients with posttransplant diabetes mellitus into 2:1 groups according to type of diabetes education. Group 1 (n = 140) received structured education, and group 2 (n = 70) received conventional education. Patient data were collected through patient identification and metabolic control parameter forms.

Results: Most patients in groups 1 and 2, respectively, were Kuwaiti (60.7% vs 58.6%), men (57.9% vs 68.6%), and had high school-level education (43.6% vs 48.6%). Chronic glomerulonephritis was the original disease in 36.4% versus 35.4% of patients. Most patients (72.8% vs 78.6% in group 1 vs 2) received pretransplant hemodialysis. At study start, the rate of patients with diabetic neuropathy was comparable between groups (32.4% vs 27.9%). Moreover, after completion of 24 months of education, neurological evaluation by electromyograph and nerve conduction studies did not show any significant differences between the groups (P > .05). Similarly, the number of patients with fundus imaging showing retinopathy was comparable between groups at start and end of study (P > .05). Although macroangiopathic events were higher in group 1, this finding was not significant (P > .05). However, although the percentage of patients with nephropathy was comparable in both groups at start of study, the percentage decreased significantly in group 1 at 24 months after completion of education compared with group 2 and baseline value (P = .016).

Conclusions: Structured diabetes education was associated with reduced diabetic nephropathy but had no significant effects on other micro- or macroangiopathies. However, we recommend education for all kidney transplant recipients with diabetes.
