ABSTRACT
UNLABELLED: Although quality of life (QoL) is an important outcome measure, there are few studies of QoL in diabetic patients. We performed a cross-sectional study to assess QoL in such patients comparable for age, sex, and co-morbidity. PATIENTS: Group CAPD: DM (n = 19, 12 males), diabetic CAPD patients; group CAPD: no DM (n = 26, 15 males) CAPD patients without diabetes; group TXP (n = 20, 10 males), diabetic transplant patients; and group CKD: DM (n = 20, 11 males), diabetics with chronic kidney disease. Two valid QoL instruments were used: a generic one (SF-36) and one that is disease-specific (RQLP). RESULTS: As a whole, CAPD patients scored badly as far as concerned the physical domain, but with a good mental adaptation. Diabetic CAPD patients exhibited worse QoL for physical functioning, energy, vitality, leisure activity, and eating/drinking limitations. Diabetic transplant patients exhibited the best QoL. The RQLP instrument had better discriminative power for domains such as eating/drinking, treatment effects, and psychosocial aspects. Using analysis of co-variance and adjusting for age, sex, and co-morbidity, QoL differences disappeared. In conclusion, diabetic CAPD patients exhibited the worst QoL though with a satisfactory mental adaptation, a renal-specific instrument had better discriminative power, and the prevention of co-morbidity is likely to improve QoL in such patients.
