Abstract

Objective. We studied circulating precursor cells CPC in type 2 diabetes mellitus T2DM with neuropathic foot lesions with or without critical limb ischemia and relationships between endothelial precursor cells EPC and peripheral neuropathy. Methods and Subjects. We measured peripheral blood CD34, CD133, and CD45 markers for CPC and KDR, CD31 markers for EPC by citofluorimetry and systemic neural nociceptor CGRP calcitonin gene related protein by ELISA in 8 healthy controls C and 62 T2DM patients: 14 with neuropathy N, 20 with neuropathic foot lesions N1, and 28 with neuroischemic recent revascularized N2 foot lesions. Timing of lesions was: acute until 6 weeks, healed, and not healed. Results. CD34+ and CD133+ were reduced in N, N1, and N2 versus C, and CD34+ were lower in N2 versus N1 . In N2 CD34+KDR+ remain elevated in healed versus chronic lesions and, in N1 CD133+31+ were elevated in acute lesions. CGRP was reduced in N2 and N1 versus C versus C  pg-mL. CD34+KDR+ correlated in N2 with oximetry and negatively in N1 with CGRP. Conclusions. CD34+ CPC are reduced in diabetes with advanced complications and diabetic foot. CD34+KDR+ and CD31+133+ EPC differentiation could have a prognostic and therapeutic significance in the healing process of neuropathic and neuroischemic lesions.
