Abstract
Fibrocystic liver diseases (FLDs) comprise a heterogeneous group of rare diseases of the biliary tree, having in common an abnormal development of the embryonic ductal plate caused by genetically-determined dysfunctions of proteins expressed in the primary cilia of cholangiocytes (and therefore grouped among the "ciliopathies"). The ductal dysgenesis may affect the biliary system at multiple levels, from the small intrahepatic bile ducts [congenital hepatic fibrosis (CHF)], to the larger intrahepatic bile ducts [Caroli disease (CD), or Caroli syndrome (CS), when CD coexists with CHF], leading to biliary microhamartomas and segmental bile duct dilations. Biliary changes are accompanied by progressive deposition of abundant peribiliary fibrosis. Peribiliary fibrosis and biliary cysts are the fundamental lesions of FLDs and are responsible for the main clinical manifestations, such as portal hypertension, recurrent cholangitis, cholestasis, sepsis and eventually cholangiocarcinoma. Furthermore, FLDs often associate with a spectrum of disorders affecting primarily the kidney. Among them, the autosomal recessive polycystic kidney disease (ARPKD) is the most frequent, and the renal function impairment is central in disease progression. CHF, CD/CS, and ARPKD are caused by a number of mutations in polycystic kidney hepatic disease 1 (PKHD1), a gene that encodes for fibrocystin/polyductin, a protein of unclear function, but supposedly involved in planar cell polarity and other fundamental cell functions. Targeted medical therapy is not available yet and thus the current treatment aims at controlling the complications. Interventional radiology or surgical treatments, including liver transplantation, are used in selected cases.

Abstract
The choice of KT only or CLKT for infantile NPHP with mild liver fibrosis is understudied. A 5-year-old girl was transferred to our center for KT due to ESRD. Her primary disease was infantile NPHP with compound heterozygous NPHP3 mutations: c.458A>C(p.Q153P)/missense mutation and c.2032A>T(p. K678X)/nonsense mutation. The patient had elevated liver enzymes and biopsy-proven liver fibrosis. As liver synthesis was acceptable, only KT was performed. However, liver fibrosis progressed at 1.5 years after transplantation, manifested with portal hypertension and hypersplenism. Common causes for portal hypertension were excluded, and the progression was attributed to NPHP. AMR attacked allograft at about 2 years post-transplant. To solve both the liver and the kidney problems, CLKT was performed. Her liver and kidney function recovered initially, but she unfortunately died of pneumonia and subsequent intracranial hemorrhage two weeks later. Nonsense mutation in NPHP3 gene may be correlated with rapid progression of liver disease in infantile NPHP. More studies are required to determine the role of CLKT in these cases; however, combined transplantation may improve long-term graft and patient survival.

Abstract
Autosomal recessive polycystic kidney disease (ARPKD) is a congenital hepatorenal fibrocystic disease. The hepatic manifestations of ARPKD can range from asymptomatic to portal hypertension and massively dilated biliary system that results in liver transplantation. Hepatic complications of ARPKD typically present with signs of portal hypertension (splenomegaly and thrombocytopenia) or cholangitis. Liver disease in ARPKD does not always correlate with severity of renal disease. Management of ARPKD-related liver disease is largely treating specific symptoms, such as antibiotics for cholangitis or endoscopic treatment for variceal bleeding. If complications cannot be managed medically, liver transplantation may be indicated. This mini-review will discuss the clinical manifestations and management of children with ARPKD liver disease.

Abstract
Autosomal recessive polycystic kidney disease (ARPKD) is associated with progressive enlargement of the kidneys fuelled by the formation and expansion of fluid-filled cysts. The disease is congenital and children that do not succumb to it during the neonatal period will, by age 10 years, more often than not, require nephrectomy+renal replacement therapy for management of both pain and renal insufficiency. Since increasing cystic index (CI; percent of kidney occupied by cysts) drives both renal expansion and organ dysfunction, management of these patients, including decisions such as elective nephrectomy and prioritization on the transplant waitlist, could clearly benefit from serial determination of CI. So also, clinical trials in ARPKD evaluating the efficacy of novel drug candidates could benefit from serial determination of CI. Although ultrasound is currently the imaging modality of choice for diagnosis of ARPKD, its utilization for assessing disease progression is highly limited. Magnetic resonance imaging or computed tomography, although more reliable for determination of CI, are expensive, time-consuming and somewhat impractical in the pediatric population. Using a well-established mammalian model of ARPKD, we undertook a big data-like analysis of minimally- or non-invasive blood and urine biomarkers of renal injury/dysfunction to derive a family of equations for estimating CI. We then applied a signal averaging protocol to distill these equations to a single empirical formula for calculation of CI. Such a formula will eventually find use in identifying and monitoring patients at high risk for progressing to end-stage renal disease and aid in the conduct of clinical trials.

Abstract
PURPOSE OF REVIEW To describe the recent increase in the understanding of the clinical manifestation of autosomal recessive polycystic kidney disease (ARPKD), which is caused by mutations in the PKHD1 gene. The change in nomenclature reflects the genetic contribution to the understanding of pleiotropic disease manifestations. The term 'hepatorenal fibrocystic disorder' or 'ARPKD-congenital hepatic fibrosis (CHF)' addresses the major organ manifestations of the disease. RECENT FINDINGS More than 300 different mutations in the PKHD1 gene have been described; however, there is no genotype-phenotype correlation. Cystic phenotype in the kidneys is highly variable. Renal oligohydramnios before 28 weeks of gestation may be lethal, whereas perinatal manifestations have a better prognosis. More than 60% of neonates with pulmonary hypoplasia may survive; about 25% need postnatal dialysis. After 10 years, 60% require renal replacement therapy. Liver fibrosis is always found and cholangiodysplasia is common. The Caroli phenotype is seen in up to 80% with perinatal manifestation. Recurrent cholangitis and cirrhosis may require liver transplantation in about 10% of patients. Neurocognitive development is in the usual range of children with moderate renal failure, but deserves further research. SUMMARY The pleiotropic manifestations of ARPKD-CHF require multidisciplinary efforts to anticipate organ complications and to improve a possible good prognosis.
