[Nocturnal hemodialysis: an alternative treatment for a better quality of life].
The interest of investigators in intensified dialysis regimens has been growing in recent years, especially since the HEMO Study Group showed that a higher dose of thrice-weekly hemodialysis fails to reduce mortality and morbidity but improves clinical outcomes. Alternative hemodialysis strategies including short daily hemodialysis (SDHD), long hemodialysis (LHD) and nocturnal daily hemodialysis (NDHD) have been developed in the hope to improve patients' outcomes. A growing number of investigators are studying patients on alternative dialysis regimens and most publications in this field have reported significant improvements in clinical outcomes including left ventricular hypertrophy, blood pressure control, anemia, calcium-phosphate metabolism, and fluid and electrolyte balance; all of these parameters can be considered as indirect signs of improvement in quality of life. However, the strength of these results is often limited by shortcomings in study design. Indeed, in most of these studies an adequate control group is missing, the patient groups are not properly matched, and the number of patients enrolled is small. Similarly, most studies have evaluated the effects of NDHD and/or nocturnal LHD on health-related quality of life (HRQoL) by questionnaire administration. Even though better results might be achieved with nocturnal hemodialysis, no conclusive data exist to prove statistically significant differences in HRQoL between conventional and intensive hemodialysis. In conclusion, all of these novel dialysis strategies offer reliable opportunities for uremic patients, but further trials are needed to determine whether alternative hemodialysis can reduce morbidity and mortality in this high-risk population of patients.
