Abstract:

Objective

The objective of this study was to evaluate the safety and efficacy of umbilical cord mesenchymal stem cell (UC-MSCs) infusion for patients with ursodeoxycholic acid (UDCA) -resistant primary biliary cirrhosis (PBC) , and analyzed related factors influencing the therapeutic effect of UC-MSCs.

Methods

Twenty-nine patients with UDCA-resistant PBC were enrolled in this trial of UC-MSCs from August 2010 to October 2017 in the Fifth Medical Center of Chinese PLA General Hospital. UC-MSCs were intravenously infused 3 times at a density of 1.0×106 cells per kg of body weightat intervals of 4 weeks. The safety of UC-MSCs treatmentwas measured using vital signs, laboratory tests and occurrence of adverse events. The clinical symptoms, liver function indexes, and Child-Pugh scores were used to evaluate the efficacy of UC-MSCs treatment. The "Paris I criteria" was used as the curative effect standard to evaluate the curative effect response of patients after UC-MSCs treatment, to compare the differences in baseline clinical symptoms and liver function between the effective and ineffective patients, and to analyze the related factors affecting the curative effect of UC-MSCs. Student t test was used to analyze age, Mann-Whitney U test was used to compare the time of UDCA treatment, hormone treatment time and laboratory data between the two groups, Wilcoxon rank sum test was used to compare the data between groups, and χ2 test was used to compare the gender, clinical symptoms, Child-Pugh grading and other indicators. Multivariate Cox regression analysis on the related factors affecting the efficacy of UC-MSCs.

Results

One patient developed high fever due to severe infection after treatment, and no serious adverse events related to UC-MSCs occurred in all patients. Serum alkaline phosphatase (ALP) [281.00 (182.50, 428.50) vs 201.00 (149.50, 402.00) ], γ-glutamyltransferase (GGT) [156.00 (73.00, 390.00) vs 84.00 (43.50, 312.50) ], and total cholesterol (TC) [5.10 (3.14, 7.69) vs 3.94 (3.00, 6.01) ] decreased after UC-MSCs infusion compared with baseline (P all < 0.05) . Among them, 9 patients (31﹪) had obvious curative effect after treatment and reached the "Paris I standard". Compared with the baseline of 20 patients in the ineffective group, aspartate aminotransferase (AST) [53.00 (46.00, 78.00) vs 93.50 (77.75, 100.75) ], ALP [185.00 (152.50, 295.50) vs 342.00 (237.25, 516.00) ], and total bilirubin (TBIL) [13.10 (11.25, 20.25) vs 58.50 (33.45, 69.33) ] were all lower than those in the ineffective group (P all < 0.05) . Multivariate Cox regression analysis showed that serum TBIL was an important independent factor affecting the efficacy of UC-MSCs [HR:0.817 (95﹪CI: 0.715 ~ 0.935) , P < 0.05].

Conclusions

UC-MSCs infusion was safe, feasible and well-tolerated in PBC patients who resistant to UDCA, and some patients have improved liver function. Serum TBIL was an independent important factor affecting the therapeutic efficacy of UC-MSCs, suggesting that UC-MSCs treatment in the early stage of disease progression with low TBIL may effectively improve and slow down the disease process of patients.
