Abstract:

BACKGROUND: There has been limited study of the prevalence of gastrointestinal symptoms and their impact on the quality of life (QOL) in kidney transplant recipients. The aim of this study was to examine the prevalence and predictors of gastrointestinal symptoms and the association with QOL in kidney transplant recipients. METHODS: All chronic kidney transplant recipients at the Princess Alexandra Hospital were provided with 3 questionnaires, the Gastrointestinal Quality of Life Index (GIQLI), the Gastrointestinal Symptoms Rating Scale (GSRS), and Structured Assessment of Gastrointestinal Symptoms (SAGIS) scale, to ascertain QOL impairment and to screen gastrointestinal symptom severity. Linear regression was used to determine the predictors of gastrointestinal QOL and gastrointestinal symptom severity. RESULTS: Of the 343 participants, the median age was 47 (interquartile range [IQR] 36-55) years, 58% were men, 79% were white, 39% had chronic glomerulonephritis, 83% had received their first graft, and median time since transplant was 6.3 (IQR 1.8-13.1) years. Using GSRS, 88% of participants reported at least 1 gastrointestinal symptom, most commonly indigestion (57%) and diarrhea (54%). Using GIQLI, 42% and 38% of participants reported mild and moderate QOL impairment, respectively. Gastrointestinal symptoms were predicted by female sex (coefficient -0.11, 95% CI -0.21 to -0.02) and mycophenolate (coefficient 0.0001, 95% CI 0.0001 to 0.0002), and were associated with poorer QOL (coefficient -0.38, 95% CI -0.45 to -0.30). Similar findings were observed using SAGIS for gastrointestinal symptoms. CONCLUSIONS: Gastrointestinal symptoms are frequent in kidney transplant recipients, particularly in women and those receiving mycophenolate, and are strongly associated with poorer QOL.
