Background
Microalbuminuria is a prognostic marker of diabetes kidney disease. It is generally diagnosed as the ratio of urinary albumin to creatinine (UACR) of 30-300 mg/g. Hashimoto’s thyroiditis is a common disease in the endocrinology and the thyroid antibodies may associated with kidney disease. We investigated the UACR in the newly diagnosed T2DM with Hashimoto’s thyroiditis and tried to detect the relationship between the UACR and thyroid antibodies.
Methods
One hundred twenty newly diagnosed T2DM patients with Hashimoto’s thyroiditis and euthyroidism and 50 sex and age-matched T2DM with non-Hashimoto’s and other thyroid disease were recruited. T2DM patients were divided into 2 groups by the titer of TPOAb: (1). TPOAb (+) group: T2DM with positive TPOAb (n = 105); (2). TPOAb (−) group: T2DM with negative TPOAb (n = 65).
Results
T2DM with positive TPOAb group had higher UACR than T2DM with negative TPOAb group (21.55 ± 7.28 vs 15.13 ± 5.69 mg/g, P < 0.01). UACR were positively related to BMI (r = 0.255, P < 0.05), FPG (r = 0.285, P < 0.05), HbA1c (r = 0.260, P < 0.05) and TPOAb (r = 0.349, P < 0.05). HbA1c (β = 0.793, P < 0.05), BMI (β = 0.342, P < 0.05) and lnTPOAb (β = 1.207, P < 0.05) were independently associated with UACR.
Conclusions
In the newly diagnosed T2DM patients, Hashimoto’s thyroiditis with TPOAb positive had higher UACR levels. TPOAb titer, BMI and HbA1c were independent associated with UACR in these patients.
