Monitoring of patients with type 2 diabetes and nephropathy in a specialized diabetic nephropathy clinic seems to be beneficial.

BACKGROUND

The purpose of this study was to evaluate the outcome of DM2 patients with nephropathy when they are under surveillance of a joined clinic run by endocrinologists & nephrologists.

PATIENTS AND

METHODS

A cohort of 106 patients with DM2, 42-83 years of age, and eGFR < 60 ml/min/m2 were included. Age, sex, duration of diabetes, duration of attending our clinic, smoking habits, BMI, data regarding ischemic heart disease and induction of hemodialysis, urine albumin excretion (UAE) levels, eGFR (MDRD equation) and values of various biochemical parameters were recorded too. Follow-up period ranged from one to 25 years. Paired samples t-test and non-parametrical Kruskal-Wallis test were used for the analyses of the data.

RESULTS

Fifty percent of patients had no further progression, 25.9% improvement, while 24.1% had worsening of the UAE levels. During the follow-up in the joined clinic, there was a smaller than the expected from the medical literature decrease in median eGFR, i.e. 2,3 ml/min/m2 and a statistically significant improvement in glycosylated hemoglobin levels from 8.0% to 7.4% (p = 0.016). Time in years of follow-up in the joined clinic of our hospital appeared to be the most significant factor in the improvement or stabilization against deterioration of the UAE levels (p = 0.018).

CONCLUSIONS

Close follow-up of DM2 patients with eGFR < 60 ml/min/m2 has resulted in a minor annual eGFR decrease. Monitoring of these patients in a specialized diabetic nephropathy clinic is beneficial for this group of patients for delaying the occurrence of end-stage renal disease.
