Autologous Dendritic Cells(Mayo Clinic)

Type 2 diabetes mellitus (T2DM) is a global health concern, with diabetic neuropathy (DN) being a prevalent complication. Current DN treatments focus on blood glucose control and pain management, which show limited efficacy. This study explored the effects of autologous dendritic cell (DC) administration on improving DN symptoms. A quasi-experimental clinical trial was conducted on 28 DN patients at Gatot Soebroto Army Hospital. Patients received autologous DC administration, with their Toronto Clinical Neuropathy Score (TCNS), Transforming Growth Factor-β (TGF-β), and Vascular Cell Adhesion Molecule-1 (VCAM-1) levels measured before and at four weeks after treatment. The results show an average TCNS reduction from 8.93 to 7.5 (p < 0.001). TGF-β levels increased slightly from 41.16 ng/mL to 44.18 ng/mL (p > 0.05). VCAM-1 levels increased from 1389.75 ng/mL to 1403.85 ng/mL. Correlation analysis showed that TGF-β levels had a significant negative correlation with the TCNS (r = −0.353; p = 0.033) and VCAM-1 levels (r = −0.521; p = 0.002). Autologous DC administration significantly improves DN. While the changes in TGF-β and VCAM-1 levels were not statistically significant, their trends suggest that there was an anti-inflammatory effect. These findings highlight the potential of autologous DC therapy as a complementary approach to manage DN through inflammation reduction and nerve repair.
