Improved health-related quality of life and left ventricular hypertrophy among dialysis patients treated with parathyroidectomy.

BACKGROUND

We prospectively studied changes in the perception of health-related quality of life, pruritus, and degree of left ventricular hypertrophy in end-stage renal disease patients with tertiary hyperparathyroid disorder, before and 6 months after total parathyroidectomy treatment.

METHODS

A series of 12 consecutive patients were enrolled. Throughout the follow-up period, all subjects completed the Kidney Disease Quality of Life Short Form-36 (KDQOL SF-36) questionnaire at inclusion and after 6 months. Serial clinical and physiological parameters including uremic pruritus, blood pressure control and left ventricular hypertrophy measured by echocardiography were recorded.

RESULTS

Mean scores of the KDQOL SF-36 questionnaires were substantially higher 6 months after parathyroidectomy, with reference to physical functioning, bodily pain, role-physical, role-emotional, symptom list and burden of kidney disease. Parathyroidectomy resulted in a 22% reduction in left ventricular mass index, with significant improvement from the baseline value of 246 +/- 131 to 192 +/- 131 g/m2 (p = 0.03).

CONCLUSION

Our findings highlight the potential importance of parathyroidectomy in improving health-related quality of life and left ventricular hypertrophy among dialysis patients with tertiary hyperparathyroidism.
