Chronic kidney disease and its relationship with mental health: Allostatic load perspective for integrated care

Background: Chronic renal failure is a chronic medical condition characterized by a progressive and irreversible loss of kidney function. Up to 50% of patients undergoing dialysis experience symptoms of depression and anxiety: what is the impact of individual factors and medical conditions on the mental health issue? The present study was carried out to investigate the individual factors (biomarkers and psychological dimensions) of end-stage renal disease patients dealing with dialysis, analyzing their predictor values for developing negative disease adaptations by an allostatic paradigm. Methods: We conducted an observational study on 35 patients affected by end-stage renal disease; biological and psychological markers have been detected. We conducted descriptive statistical analyses (t-tests) and performed a hierarchical regression analysis to investigate the relationship between pathological medical conditions and psychological dimensions. Results: The findings showed a positive correlation between creatinine levels and psychological distress as well as stress index. No significant effect of “time of dialysis”, “time from diagnosis”, “age” and “personality traits” was found. Conclusion: Our findings showed that personality traits did not represent a protective factor by moderating positive emotional adaptations; conversely, creatinine levels appeared predictive for negative emotional adaptations. High levels of creatinine were found to be positively associated with high stress levels as well psychological distress. According to the allostatic paradigm, end-stage renal disease patients could experience an allostatic load and more overload towards poor health outcomes; integrated biological and psychological measurements could prevent increased negative mental health through a patient-centered approach.
