Neurobehavioral functioning and survival following lung transplantation.

ABSTRACT: Neurobehavioral functioning is widely recognized as being an important consideration in lung transplant candidates, but little is known about whether these factors are related to clinical outcomes. The present study examined the relationship of neurobehavioral functioning, including measures of executive function and memory, depression, and anxiety, to long-term survival among lung transplant recipients.The sample was drawn from 201 patients who underwent transplantation at Duke University and Washington University who participated in a dual-site clinical trial investigating medical and psychosocial outcomes in transplant candidates with end-stage lung disease. All patients completed the Beck Depression Inventory-II (BDI-II) and Spielberger State-Trait Anxiety Inventory at baseline and again after 12 weeks, while a subset of 86 patients from Duke University also completed neurocognitive testing. Patients were followed for survival up to 12 years after completing baseline assessments.One hundred eleven patients died over a mean follow-up of 10.8 years (SD=0.8). Baseline depression, anxiety, and neurocognitive function were examined as predictors of posttransplant survival, controlling for age, 6-min walk distance, FEV, and native disease; education and cardiovascular risk factors were also included in the model for neurocognition. Lower executive function (hazard ratio [HR]=1.09, P=.012) and memory performance (HR=1.11, P=.030) were independently associated with greater mortality following lung transplant. Although pretransplant depression and anxiety were not predictive of mortality, patients who scored>13 on the BDI-II at baseline and after 3 months pretransplant had greater mortality (HR=1.85 [95% CI, 1.04, 3.28], P=.036).Neurobehavioral functioning, including persistently elevated depressive symptoms and lower neurocognitive performance, was associated with reduced survival after lung transplantation.ClinicalTrials.gov; No.: NCT00113139; URL: www.clinicaltrials.gov.

Project description:Background:There is mixed evidence regarding the nature of cognitive function in patients who have undergone renal transplantation. The aim of this meta-analysis was to examine which cognitive domains are impacted following kidney transplantation and how performance compares with non-transplanted patients or healthy controls/normative data. Method:A systematic search was conducted using keywords within three databases (Embase, MEDLINE and PsychINFO), yielding 458 unique studies, 10 of which met the inclusion criteria. Neuropsychological tests were grouped into nine cognitive domains and three separate analyses were undertaken within each domain: (i) within subjects pre- versus post-transplant, (ii) transplanted versus non-transplanted patients and (iii) transplanted versus healthy matched controls and standardized normative data. Results:Transplanted patients showed moderate to large improvements in the domains of general cognitive status (g = 0.526), information and motor speed (g = 0.558), spatial reasoning (g = 0.376), verbal memory (g = 0.759) and visual memory (g = 0.690) when compared with their pre-operative scores. Test scores in the same five domains were significantly better in post-transplanted patients when compared with dialysis-dependant or conservatively managed chronic kidney disease patients. However, post-transplanted patients' performance was significantly low compared with that of healthy controls (and standardized normative data) in the domains of executive functioning (g = -0.283), verbal fluency (g = -0.657) and language (g = -0.573). Conclusions:Two key issues arise from this review. First, domain-specific cognitive improvement occurs in patients after successful transplantation. Nevertheless, transplanted patients still performed significantly below healthy controls in some domains. Second, there are important shortcomings in existing studies; the length of follow-up is typically short and only limited neuropsychological test batteries are employed. These factors are important in order to support the recovery of cognitive function among patients following renal transplant.
