Transient Elastography for Detection of Liver Fibrosis in Children With Autosomal Recessive Polycystic Kidney Disease.

Front Pediatr 2018 11;6:422. Epub 2019 Jan 11.

Department of Gastroenterology, Hepatology, Feeding Disorders and Pediatrics, Children's Memorial Health Institute, Warsaw, Poland.

Congenital hepatic fibrosis (CHF) is invariably present in all patients with autosomal recessive polycystic kidney disease (ARPKD) but is usually clinically asymptomatic. The portal hypertension in the course of CHF develops and progresses over time, so an early detection of liver fibrosis remains crucial. The aim of the study was to evaluate a predictive value of transient elastography for evaluating liver disease progress in pediatric ARPKD patients. Read More

Increased water intake reduces long-term renal and cardiovascular disease progression in experimental polycystic kidney disease.

PLoS One 2019 2;14(1):e0209186. Epub 2019 Jan 2.

Centre for Transplant and Renal Research, Westmead Institute for Medical Research, The University of Sydney, Sydney, NSW, Australia.

Polycystic kidney disease (PKD) is the most common inherited cause of kidney failure and currently has limited treatment options. Increasing water intake reduces renal cyst growth in the pck rat (a genetic ortholog of autosomal recessive PKD) but it is not clear if this beneficial effect is present in other models of PKD. In this study, we tested the hypothesis that high water intake (HWI) reduces the progression of cystic renal disease in Lewis polycystic kidney (LPK) rats (a genetic ortholog of human nephronophthisis-9).

Kidney cysts can manifest as focal disease (simple and complex kidney cysts), affect a whole kidney (eg, multicystic dysplastic kidney or cystic dysplasia), or manifest as bilateral cystic disease (eg, autosomal recessive polycystic kidney disease [ARPKD] or autosomal dominant polycystic kidney disease [ADPKD]). In children, as opposed to adults, a larger proportion of kidney cysts are due to genetic diseases (eg, HNF1B nephropathy, various ciliopathies, and tuberous sclerosis complex), and fewer patients have simple cysts or acquired cystic kidney disease. The purpose of this consensus statement is to provide clinical guidance on standardization of imaging tests to evaluate kidney cysts in children. Read More

Molecular Genetic Analysis of PKHD1 Mutations in Pedigrees With Autosomal Recessive Polycystic Kidney Disease.

Iran J Kidney Dis 2018 Nov;12(6):350-358

Department of Medical Genetics, Tarbiat Modares University, Teheran, Iran.

Introduction: A wide variety of mutations are spread throughout the PKHD1 gene, which encodes a 4074-bp amino acid protein, namely fibrocystin/polyductin, and is responsible for all features of autosomal recessive polycystic kidney disease (ARPKD). Autosomal recessive polycystic kidney disease is a hereditary early-onset form of polycystic kidney disease characterized by fusiform dilation of collecting ducts and congenital hepatic fibrosis. The highest level of PKDH1 expression is in the kidneys of fetus and adults, suggesting the functionally importance of the gene in the mature kidney in addition to its role in kidney development.

Truncating PKHD1 and PKD2 mutations alter energy metabolism.

Am J Physiol Renal Physiol 2019 Mar 19;316(3):F414-F425. Epub 2018 Dec 19.

Department of Medicine, University of Alabama at Birmingham , Birmingham, Alabama.

Deficiency in polycystin 1 triggers specific changes in energy metabolism. To determine whether defects in other human cystoproteins have similar effects, we studied extracellular acidification and glucose metabolism in human embryonic kidney (HEK-293) cell lines with polycystic kidney and hepatic disease 1 ( PKHD1) and polycystic kidney disease (PKD) 2 ( PKD2) truncating defects along multiple sites of truncating mutations found in patients with autosomal recessive and dominant PKDs. While neither the PKHD1 or PKD2 gene mutations nor their position enhanced cell proliferation rate in our cell line models, truncating mutations in these genes progressively increased overall extracellular acidification over time ( P < 0.

G Ital Nefrol 2018 Dec;35(6)

U.O.C. Nefrologia, Università cattolica del sacro cuore. Fondazione Policlinico Universitario A. Gemelli IRCCS, Roma, Italia.

ADH is a hormone secreted by neurohypophysis that plays different roles based on the target organ. At the renal level, this peptide is capable of causing electrolyte-free water absorption, thus playing a key role in the hydro-electrolytic balance. There are pathologies and disorders that jeopardize this balance and, in this field, ADH receptor inhibitors such as Vaptans could play a key role. Read More

Polycystic kidney disease.

Nat Rev Dis Primers 2018 Dec 6;4(1):50. Epub 2018 Dec 6.

Division of Nephrology and Hypertension, Mayo Clinic, Rochester, MN, USA.

Cystic kidneys are common causes of end-stage renal disease, both in children and in adults. Autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD) are cilia-related disorders and the two main forms of monogenic cystic kidney diseases. ADPKD is a common disease that mostly presents in adults, whereas ARPKD is a rarer and often more severe form of polycystic kidney disease (PKD) that usually presents perinatally or in early childhood.

Prenatal MR imaging features of Caroli syndrome in association with autosomal recessive polycystic kidney disease.

Radiol Case Rep 2019 Feb 26;14(2):265-268. Epub 2018 Nov 26.

Department of Radiology, The Children's Hospital of Philadelphia, 34th Street and Civic Center Boulevard, Philadelphia, PA 10104, USA.

Caroli syndrome, which is characterized by saccular and fusiform dilatation of the biliary ducts, is usually observed in association with autosomal recessive polycystic kidney disease (ARPKD). Although the diagnosis of ARPKD is generally easy to make in postnatal ultrasound, the diagnosis of Caroli syndrome may be challenging in prenatal ultrasound. Herein, we present a case of a 29-week fetus with ARPKD associated with Caroli syndrome in whom fetal magnetic resonance imaging was essential to identify the "central dot sign" within the dilated biliary ducts to confirm the prenatal diagnosis of Caroli syndrome and to increase our level of confidence in this diagnosis.

Ruptured intracranial aneurysm in a patient with autosomal recessive polycystic kidney disease.

J Neurosurg Pediatr 2018 Oct 1:1-5. Epub 2018 Oct 1.

Departments of1Neurological Surgery and.

Aneurysmal rupture can result in devastating neurological consequences and can be complicated by comorbid disease processes. Patients with autosomal recessive polycystic kidney disease (ARPKD) have a low rate of reported aneurysms, but this may be due to the relative high rate of end-stage illnesses early in childhood. Authors here report the case of a 10-year-old boy with ARPKD who presented with a Hunt and Hess grade V subarachnoid hemorrhage requiring emergency ventriculostomy, embolization, and decompressive craniectomy.

Department of Physiology, Medical College of Wisconsin, 8701 Watertown Plank Road, Milwaukee, WI, 53226, USA.

Polycystic kidney diseases (PKDs) are a group of inherited nephropathies marked by formation of fluid-filled cysts along the nephron. Growing evidence suggests that in the kidney formation of cysts and alteration of cystic electrolyte transport are associated with purinergic signaling. PCK/CrljCrl-Pkhd1pck/CRL (PCK) rat, an established model of autosomal recessive polycystic kidney disease (ARPKD), was used here to test this hypothesis. Read More

Electronic address:

Autosomal Recessive Polycystic Kidney Disease (ARPKD) is a genetic disorder with an incidence of ~1:20,000 that manifests in a wide range of renal and liver disease severity in human patients and can lead to perinatal mortality. ARPKD is caused by mutations in PKHD1, which encodes the large membrane protein, Fibrocystin, required for normal branching morphogenesis of the ureteric bud during embryonic renal development. The variation in ARPKD phenotype suggests that in addition to PKHD1 mutations, other genes may play a role, acting as modifiers of disease severity. Read More

Division of Clinical Genetics, Department of Laboratory Medicine, Faculty of Medicine, University of Debrecen, 4032 Debrecen, Nagyerdei krt. 98., Debrecen, Hungary.

Background: Autosomal recessive polycystic kidney disease (ARPKD) is genetically one of the least heterogeneous ciliopathies, resulting primarily from mutations of PKHD1. Nevertheless, 13-20% of patients diagnosed with ARPKD are found not to carry PKHD1 mutations by sequencing. Here, we assess whether PKHD1 copy number variations or second locus mutations explain these cases. Read More

Department of Pediatrics, University Hospital of Cologne, Cologne, Germany.

Autosomal recessive polycystic kidney disease (ARPKD) is a severe hepatorenal disorder of childhood. Early renal disease in ARPKD may require renal replacement therapy and is associated with failure to thrive resulting in a need for nasogastric tube feeding or gastrostomy. In ARPKD patients, the benefit of a gastrostomy in nutrition and growth needs to be weighed against the potential risk of complications of congenital hepatic fibrosis (CHF) and portal hypertension like variceal bleeding.

Autosomal recessive polycystic kidney disease (ARPKD) is a monogenic disease characterized by development of hepatorenal cysts, pericystic fibrosis, and inflammation. Previous studies show that mast cell (MC) mediators such as histamine induce proliferation of cholangiocytes. We observed robust MC accumulation around liver cysts, but not kidney cysts, in polycystic kidney (PCK) rats (an animal model of ARPKD). Read More

Department of Pediatrics, Case Western Reserve University, Cleveland, Ohio.

BackgroundAutosomal recessive polycystic kidney disease (ARPKD) is associated with significant mortality and morbidity, and currently, there are no disease-specific treatments available for ARPKD patients. One major limitation in establishing new therapies for ARPKD is a lack of sensitive measures of kidney disease progression. Magnetic resonance imaging (MRI) can provide multiple quantitative assessments of the disease. Read More

Genetics of Autosomal Recessive Polycystic Kidney Disease and Its Differential Diagnoses.

Authors:
Carsten Bergmann

Front Pediatr 2017 9;5:221. Epub 2018 Feb 9.

Center for Human Genetics, Bioscientia, Ingelheim, Germany.

Autosomal recessive polycystic kidney disease (ARPKD) is a hepatorenal fibrocystic disorder that is characterized by enlarged kidneys with progressive loss of renal function and biliary duct dilatation and congenital hepatic fibrosis that leads to portal hypertension in some patients. Mutations in the gene are the primary cause of ARPKD; however, the disease is genetically not as homogeneous as long thought and mutations in several other cystogenes can phenocopy ARPKD. The family history usually is negative, both for recessive, but also often for dominant disease genes due to arisen mutations or recessive inheritance of variants in genes that usually follow dominant patterns such as the main ADPKD genes and .

Aberrant Regulation of Notch3 Signaling Pathway in Polycystic Kidney Disease.

Sci Rep 2018 Feb 20;8(1):3340. Epub 2018 Feb 20.

Department of Internal Medicine, University of Kansas Medical Center, Kansas City, Kansas, United States.

Polycystic kidney disease (PKD) is a genetic disorder characterized by fluid-filled cysts in the kidney and liver that ultimately leads to end-stage renal disease. Currently there is no globally approved therapy for PKD. The Notch signaling pathway regulates cellular processes such as proliferation and de-differentiation, which are cellular hallmarks of PKD.

Combined and sequential liver-kidney transplantation in children.

Pediatr Nephrol 2018 Dec 10;33(12):2227-2237. Epub 2018 Jan 10.

Department of Surgery & Organ Transplantation, The Children's Memorial Health Institute, Warsaw, Poland.

Combined and sequential liver-kidney transplantation (CLKT and SLKT) is a definitive treatment in children with end-stage organ failure. There are two major indications: - terminal insufficiency of both organs, or - need for transplanting new liver as a source of lacking enzyme or specific regulator of the immune system in a patient with renal failure. A third (uncommon) option is secondary end-stage renal failure in liver transplant recipients. Read More
