Abstract:
Objective:To explore the attitude of kidney transplant (KT) recipients towards xenotransplantation and explore its related influencing factors to provide auxiliary references for the clinical research of xenotransplantation in China.Methods:The questionnaire data of "Attitude survey of KT recipients towards xenotransplantation" were collected from 194 KT recipients followed up at Organ Transplant Center of Affiliated Tongji Hospital. Nonparametric tests were utilized for comparing score differences and χ2 tests for comparing responses to specific questions. Variables with statistical significance in non-parametric test were included into multifactor linear regression analysis for exploring the influencing factors of recipients' attitudes towards xenotransplantation. Results:KT recipients had a higher score (75 points) on attitude scale of xenotransplantation. "Cognitive preference" dimension scored the highest (85 points); "Fear of risk" dimension scored lowest (50 points). The results of univariate analysis indicated that gender ( P=0.020), medical background ( P=0.006) and knowledge of clinical trial cases ( P<0.001) were the influencing factors of score of cognitive preference. Educational background ( P=0.029) was the factor affecting the score of "risk concern" dimension. Age ( P=0.028) and knowledge of clinical trial cases ( P=0.001) were the factors influencing the score of "psychosocial" dimension. Whether medical background ( P=0.018) and knowledge of clinical trial cases ( P=0.008) were the factors influencing the score of "efficacy expectation" dimension; Gender ( P=0.010), medical background ( P=0.018) and knowledge of clinical trial cases ( P=0.008) were the factors influencing total score. The results of multi-factor analysis revealed that gender ( B=-0.821, 95% CI: -1.419~0.223, P=0.007), medical background ( B=0.938, 95% CI: 0.097~1.779, P=0.029) and knowledge of clinical trials of xenotransplantation in the United States ( B=1.498, 95% CI: 0.887~2.110, P<0.001) was the influencing factor of cognitive preference. Educational background (B=-0.693, 95% CI: -1.353~-0.034, P=0.040) was the influencing factor of score on "risk concern" dimension. Knowledge of clinical trials of xenotransplantation in the United States ( B=1.075, 95% CI: 0.418~1.731, P=0.001) was an influencing factor of score on "social psychological" dimension; Knowledge of clinical trials of xenotransplantation in the United States ( B=0.710, 95% CI: 0.063~1.358, P=0.032) was an influencing factor of score on "efficacy expectation" dimension; Gender ( B=-2.259, 95% CI: -4.094~-0.423, P=0.016), medical background ( B=2.799, 95% CI: 0.219~5.378, P=0.034) and knowledge of clinical trials of xenotransplantation in the United States ( B=3.237, 95% CI: 1.360~5.114, P=0.001) were the influencing factors of total score. Conclusions:KT recipients have a higher awareness rate of xenotransplantation and a better acceptance of xenotransplantation in general. Those males with medical background and knowing clinical cases of xenotransplantation demonstrate a better attitude towards xenotransplantation. More concerned about the risk of infection, respondents expect heterologous pig kidneys to achieve the same long-term survival as allogeneic kidneys.
