DHPLC has been established as a rapid mutation screening method for ARPKD. The mutation detection rate was high in severely affected patients (85%), lower in those with moderate ARPKD (41.9%), and low, but significant, in adults with congenital hepatic fibrosis/Caroli's disease (32.1%). The prospects for gene-based diagnostics are complicated by the large gene size, marked allelic heterogeneity, and clinical diversity of the ARPKD phenotype. Identification of some common mutations, especially in specific populations, will aid mutation screening.

The most significant prognostic factor for the future development of CRF is the GFR at 1 year old. The onset of proteinuria during the follow-up is associated with a worse prognosis. Echogenic renal changes may help to identify those dysplastic kidneys that will develop RI. Neonatal boys in RI who underwent pyelo-ureterostomy had better RF during the first years of life than those who underwent valve ablation.

The health-related quality of life (HRQOL) of adolescents with end-stage renal disease (ESRD) is an important marker of disease burden. Our aims were to investigate HRQOL in a group of children and adolescents with ESRD and to compare them with the reference population norms. Ours was a cross-sectional study of 81 patients aged 10 years to 21 years with ESRD (68 with kidney transplants and 13 on dialysis) at five Spanish paediatric nephrology centres. HRQOL was investigated with the Spanish version of the child health and illness profile, adolescent edition (CHIP-AE). Clinical variables such as underlying diagnosis, number of rejection episodes, pre-emptive transplantation, anaemia and height were also analysed. No differences were found between patients with kidney transplants and their healthy peers in any domain or sub-domain of CHIP-AE. The group on dialysis scored lower than healthy controls and patients with transplants for satisfaction with health. Discomfort was higher in patients with transplants who had suffered one rejection episode. Physical discomfort was increased in anaemic patients with transplants. Short patients scored less in the satisfaction domain, with lower self-esteem and lower satisfaction with health. Adolescents with kidney transplants had better satisfaction with health than the group on dialysis, which matched the level of a healthy population. Further long-term prospective research is warranted.
