Diabetes is associated with mishandling of thiamine in the kidney and development of diabetic nephropathy. The aim of this study is to assess the disturbance of thiamine and other B-vitamin status of patients with type 2 diabetes in Indonesia.
One hundred and fifteen patients with type 2 diabetes with and without microalbuminuria or albuminuria and 39 healthy people were recruited. After a 2-month washout period for B-vitamin supplementation, markers of vitamins B1, B6, B9 and B12, were determined.
Fractional excretion of thiamine (22.8 versus 33.5%; P<0.05) and urinary excretion of the vitamin B6 degradation product 4-pyridoxic acid (0.081 versus 0.133μmol/g creatinine, P<0.001) was increased in patients with type 2 diabetes with respect to healthy controls. There was also increased total plasma cobalamin (398 versus 547pmol/l, P<0.001) and holotranscobalamin (74 versus 97pmol/l, P<0.001) in patients with type 2 diabetes. In multiple regression analysis these were linked to HbA1c, duration of diabetes and systolic blood pressure, and fasting plasma glucose, folate and C-reactive protein, respectively.
There was renal mishandling of thiamine, increased degradation of vitamin B6 and cytosolic metabolic resistance to vitamin B12 in patients with type 2 diabetes in Indonesia.
