ABSTRACT
The aim of this study was to investigate whether sulodexide treatment is capable of influencing urinary albumin excretion rate (UAER) in insulin-dependent diabetes mellitus patients (type I) with micro- or macroalbuminuria. A total of 14-inpatients (seven with micro and seven with macroalbuminuria) were enrolled and were treated first intramuscularly with a 60 mg vial of sulodexide/day for 10 days, and then orally with 25 mg capsules twice a day for 21 days. UAER was estimated before starting treatment (T0), after the i.m. treatment phase (T1) and at the end of the oral treatment (T2). No statistically significant differences in hematochemical and coagulative parameters were registered after treatment, with respect to basal values. On the contrary, a marked decrease in UAER mean values was registered at the end of both the parenteral and the oral treatment periods (T0: 349.9 mg/24 h, range 80-820; T1: 237 mg/24 h, range 7-620; T2: 91.4 mg/24 h, range: 2-306). All the differences were statistically significant (P < 0.001) versus baseline. At T2, a normalisation of UAER was observed in three microalbuminuric and in two macroalbuminuric patients, and a remarkable decrease was found in additional four and five patients, respectively. UAER was found to be still significantly lower than at baseline after 6 weeks of follow-up. This preliminary study suggests that sulodexide is effective in reducing UAER in type I patients with diabetic nephropathy.
