OBJECTIVE::
It has been shown that galectin-3 (Gal-3) promotes angiogenesis and new vessel formation. Serum Gal-3 is a risk factor for vascular complications in type 2 diabetes. The aim of this study is to compare Gal-3 levels with a range of biochemical parameters.

METHOD::
A prospective study consisted of individuals as a control group (group 1), patients diagnosed with type 2 diabetes without DFUs (group 2), and patients with type 2 diabetes with a DFU (group 3). Patient levels of endothelin-1 (ET-1), vascular endothelial growth factor-A (VEGF-A), nitric oxide (NO), and Gal-3 were measured.

RESULTS::
In total, 91 patients participated, (28 male, 63 female with a mean age of 55.83±6.35 years) Mean ET-1 (39.0±16.9), NO (17.6±7.6), VEGF-A (33.5±13.4) and Gal-3 (535.1±420.5) levels were significantly higher in group 3 compared with the other two groups (p<0.01). Furthermore, the Gal-3 level was positively and statistically significantly correlated with C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), ET-1 and NO levels in all groups.

CONCLUSION::
In our study, the level of Gal-3 was shown to be positively correlated with the VEGF-A level. Hence, Gal-3 can be considered as a defence mechanism against complications of diabetes, thus contributing to wound healing. Gal-3 may play a critical role in DFU formation and progression. Moreover, it could be suggested that Gal-3 may give an indication of prognosis, as it elevates VEGF-A levels and stimulates angiogenesis. Further studies are required to confirm the findings of this stu
