221-OR: Does Cell Therapy Improve the Quality of Life of Patients with Chronic Limb-Threatening Ischemia? A Randomized Controlled Trial

Background: Autologous cell therapy (ACT) is the last option for patients with no-option chronic limb-threatening ischemia (NO-CLTI) and severe pain. The aim of our study was to assess the impact of ACT on a patient’s quality of life, chronic pain and depression using standardized questionnaires. Methods: Forty patients with NO-CLTI were randomized and divided into groups treated initially with ACT (iACT, n=20) or standard conservative therapy (iST, n=16); 4 patients dropped out of the study. After 3 months, those in the standard therapy (ST) group were switched to (cell therapy crossover). All patients filled out the standardized EQ-5D questionnaire assessing their quality of life. Pain was evaluated using a special questionnaire including the Visual Analogue Scale (VAS) and Wong-Baker Faces (WB). The questionnaires were evaluated before randomization; in the iST group at 3 months after ST and then at 3 months after ACT. Results: Pain was significantly reduced in the iACT group after 3 months compared to baseline in both VAS and WB scores (both p Conclusion: Our study showed significant pain reduction in NO-CLTI patients after ACT; this treatment also led to a decrease in depression rate and overall improvement in their quality of life.
