Introduction: Using mesenchymal stem cells (MSCs) is regarded as a new therapeutic approach for improving fibrotic diseases.The aim of this study to evaluate the feasibility and safety of systemic infusion of autologous adipose tissue-derived MSCs(AD-MSCs) in peritoneal dialysis (PD) patients with expected peritoneal fibrosis.
Methods: This study was a prospective, open-label, non-randomized, placebo-free, phase I clinical trial. Case group consisted of nine eligible renal failure patients with more than two years of history of being on PD. Autologous AD-MSCs were obtained through lipoaspiration and expanded under good manufacturing practice conditions. Patients received 1.2 Â± 0.1Ã—106 cell/kg of AD-MSCs via cubital vein and then were followed for six months at time points of baseline, and then 3 weeks, 6 weeks, 12 weeks, 16 weeks and 24 weeks after infusion. Clinical, biochemical and peritoneal equilibration test (PET) were performed to assess the safety and probable change in peritoneal solute transport parameters.
Results: No serious adverse events and no catheter-related complications were found in the participants. 14 minor reported adverse events were self-limited or subsided after supportive treatment. One patient developed an episode of peritonitis and another patient experienced exit site infection, which did not appear to be related to the procedure. A significant decrease in the rate of solute transport across peritoneal membrane was detected by PET (D/P cr=0.77 vs.0.73, P=0.02).
Conclusions: This study, for the first time, showed the feasibility and safety of AD-MSCs in PD patients and the potentials for positive changes in solute transport. Further studies with larger samples, longer follow-up, and randomized blind controlgroups to elucidate the most effective route, frequency and dose of MSCs administration, are necessary (Registration Number:IRCT2015052415841N2).
