Pain affects health-related quality of life in kidney transplant recipients.

AbstractBACKGROUND:
Chronic pain is prevalent in end-stage renal disease patients undergoing chronic hemodialysis. We do not fully know the intensity of chronic pain experienced by kidney recipients in comparison to those on chronic hemodialysis and healthy controls. Moreover, the effect of chronic pain on kidney recipients' health-related quality of life (HRQoL) is yet to be comprehensively addressed. We designed this study to find an answer to these questions.
METHODS:
In this case control study, we studied 205 kidney recipients, 69 hemodialysis patients, and 100 healthy controls, who were matched for age, sex, monthly family income, and educational level. The patients were evaluated for the intensity of chronic pain by Visual Analogue Scale (VAS). HRQoL was measured with Short Form 36 (SF-36) in the kidney recipients. Chronic pain intensity was compared in the study groups, and in the kidney recipients the correlation between SF-36 subscores and severity of pain was assessed.
RESULTS:
Severity of pain in the kidney recipients was lower than the hemodialysis patients, but more than the healthy controls (P=.001). The VAS pain score negatively correlated with the scores of SF- 36 total (r=-.329, P=01), mental health (r=-.190, P=07), physical health (r=-.275, P=.001), physical function (r=-.339, P=.001), role limitation due to physical problems (r=-.478, P=.001), role limitation due to emotional problems (r=-.326, P=.001), and bodily pain (r=-.894, P=.001).
DISCUSSION:
The intensity of chronic pain experienced by the kidney recipients is less than that experienced by patients under chronic hemodialysis, but higher than healthy subjects. Focusing on chronic pain as a cause of post-renal transplantation morbidity is expected to improve post-renal transplantation quality of life.
