Bonventre and his colleagues studied cells obtained from five PKD patients: three with ADPKD and two with ARPKD.
When the researchers examined these cells under the microscope, they discovered that the polycystin-2 protein traveled normally to the antenna, or cilium, in cells from ARPKD patients, but it had trouble reaching the antenna in ADPKD patients.
Molecular prenatal diagnostic techniques can be used to detect ARPKD
in early pregnancy.
No existen datos sistematicos disponibles de la sensibilidad y especificidad de la ecografia prenatal en el diagnostico de ARPKD
The data presented this week in ARPKD
add to our overall understanding of PKD," said Dr.
has an incidence of 1/20 000 live births and demonstrates a variable clinical progression.
And soon into the pregnancy it was picked up that she too was suffering from ARPKD
90) Although a rare disorder with 1 affected of 20 000 newborns, ARPKD
is a severe congenital disorder manifesting with large cystic kidneys, congenital hepatic fibrosis, and systemic hypertension that manifests in the early years of life with almost half of affected newborns dying soon after birth due to pulmonary hypoplasia.
59,60) Hyperechogenic unilateral or bilateral changes detected in prenatal or postnatal screening raise a long differential diagnosis, including ARPKD
, early-onset ADPKD, multicystic renal dysplasia, congenital nephrotic syndrome, cystic nephroma, and renal vein thrombosis.
6] Family history may include kidney and liver disease due to the link between Caroli Disease and ARPKD
The gene for ARPKD
encodes a protein that is called fibrocystin which is localised to cilia on the apical domain of renal collecting cells.
(also known as "infantile PKD") affects one in 10,000 to 1 in 40,000 babies.
