Preoperative psychological factors predicting graft rejection in patients undergoing kidney transplant: a pilot study

The aim of this study was to investigate whether pretransplant psychological variables included in the CBA 2.0 Primary Scale-fear, personality, obsessive-compulsive symptoms, state and trait anxiety, psychological reactions, and depression-could predict graft rejection among patients undergoing kidney transplantation.

After ethical committee approval we enrolled 33 consecutive adult patients undergoing kidney transplantation. The inclusion criteria were a stable clinical situation in an out-of-hospital setting; Italian language literacy; a minimum of secondary school-level education, and written informed consent. We excluded patients with a psychotic disturbance, neurocognitive deficit, dementia, serious mental delay (IQ <50), current alcohol or drug abuse, recent ideation or attempted suicide or nonadherence to the therapeutic protocol. Acute and/or chronic graft rejection was diagnosed according to clinical and histopathologic criteria. CBA-2,0 "Primary Scale" series of questionnaires were handed out to patients at the time of the examinations to discrem eligibility for transplantation. Analyses of variance were performed to compare psychological scores among patients with versus without graft rejection. Logistic regression analyses of psychological variables were performed to detect possible predictors for graft rejection. The results of the analysis showed that higher psychoticism scores were able to predict graft rejection (P<.05).

The findings of this study suggest that it is mandatory to preoperatively plan an holistic treatment including psychological intervention mainly focused on psychoticism.
