As most prior reviews on NA focus on adult transplant patients, there is a need for a comprehensive overview on adherence to the immunosuppressive regimen in pediatric kidney transplant patients. This systematic review searched for English-language papers (1990-2008) addressing the prevalence of NA to the immunosuppressive regimen, its consequences, determinants, and interventions in pediatric kidney transplant patients (< age 21 yr). We found 36 papers, showing a prevalence of NA (weighted mean) of 31.8% with adolescents being more at risk compared to younger patients. About 44% of all graft losses and 23% of late acute rejection episodes are associated with NA. Most studies investigated socio-economic, condition-related or treatment-related determinants. Only one educational intervention has been tested but yielded inconclusive results. NA to the immunosuppressive regimen is prevalent with serious clinical consequences in pediatric kidney transplant patients, but the economic consequences have not yet been explored. More studies on determinants of NA are needed. The literature currently lacks fully powered RCTs testing adherence-enhancing interventions. The results of this systematic review identify the gaps in the present evidence-based information regarding NA and can be used as a tool to pursue future adherence research in pediatric populations.
Few studies comprehensively assessed psychological and behavioral functioning in adolescent kidney transplant patients. The purpose of this cross-sectional study was to evaluate depression, QOL, treatment adherence and presence of side effects from the perspective of the patient and his parents, and to compare scores with norm data. All patients (age 10-18 yr) and their parents completed the following instruments: KIDSCREEN-27 (QOL), a treatment adherence interview, the MTSOSD-59R (side effects) and the Beck Depression Inventory (depression). Twenty-three of 26 patients and 22 parents agreed to participate (70% male; median age 15 yr). Adolescents rated their QOL as satisfactory, but parents reported significant problems on several QOL dimensions. Depressive symptoms occurred in 17.4%, and 75% were non-adherent with their immunosuppressive drugs (confirmed by their parents) and show other problematic health behavior, including smoking, illicit drug use, dietary non-adherence, and suboptimal exercise levels. The most frequently occurring side effects were increased appetite, fatigue and headache; the most distressing ones were hair loss or thinning of hair, warts on hands or feet, and sores in the mouth or on the lips. Our results underscore the need for regular screening and adequate treatment of the above-mentioned aspects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
