Urinary proteome signature of Renal Cysts and Diabetes syndrome in children.

Sci Rep 2019 Feb 18;9(1):2225. Epub 2019 Feb 18.

Mosaiques Diagnostics GmbH, Hannover, Germany.

Renal Cysts and Diabetes Syndrome (RCAD) is an autosomal dominant disorder caused by mutations in the HNF1B gene encoding for the transcriptional factor hepatocyte nuclear factor-1B. RCAD is characterized as a multi-organ disease, with a broad spectrum of symptoms including kidney abnormalities (renal cysts, renal hypodysplasia, single kidney, horseshoe kidneys, hydronephrosis), early-onset diabetes mellitus, abnormal liver function, pancreatic hypoplasia and genital tract malformations. In the present study, using capillary electrophoresis coupled to mass spectrometry (CE-MS), we investigated the urinary proteome of a pediatric cohort of RCAD patients and different controls to identify peptide biomarkers and obtain further insights into the pathophysiology of this disorder.

Aquaporin-3 deficiency slows cyst enlargement in experimental mouse models of autosomal dominant polycystic kidney disease.

FASEB J 2019 Feb 15:fj201801338RRR. Epub 2019 Feb 15.

Department of Pharmacology, School of Basic Medical Sciences, Peking University, Beijing, China.

Human autosomal dominant polycystic kidney disease (ADPKD) is characterized by bilateral renal cysts that lead to a decline in kidney function. Previous studies reported aquaporin (AQP)-3 expression in cysts derived from collecting ducts in ADPKD. To study the role of AQP3 in cyst development, we generated 2 polycystic kidney disease (PKD) mouse models: kidney-specific Pkd1 knockout mice and inducible Pkd1 knockout mice, each without and with AQP3 deletion.

Anti-microRNA screen uncovers miR-17 family within miR-17~92 cluster as the primary driver of kidney cyst growth.

Sci Rep 2019 Feb 13;9(1):1920. Epub 2019 Feb 13.

Dallas, Univ Texas Southwestern Med Ctr, 5323 Harry Hines Blvd., F5.206, Dallas, 75390-8856, Texas, USA.

Autosomal dominant polycystic kidney disease (ADPKD) is the leading genetic cause of renal failure. We have recently shown that inhibiting miR-17~92 is a potential novel therapeutic approach for ADPKD. However, miR-17~92 is a polycistronic cluster that encodes microRNAs (miRNAs) belonging to the miR-17, miR-18, miR-19 and miR-25 families, and the relative pathogenic contribution of these miRNA families to ADPKD progression is unknown.

[Diagnosis of Biliary Hamartomatosis in Kidney Transplant Recipient affected by ADPKD].

G Ital Nefrol 2019 Feb;36(1)

UO Nefrologia e Dialisi, Policlinico Germaneto, Catanzaro.

Biliary hamartomas (BH) are rare benign lesions of the liver characterized by a dilation of a variable number of small biliary ducts, usually surrounded by abundant fibrotic tissue. These malformations are due to an aberrant remodelling of the ductal plate, that is the embryonic structure generating the normal biliary tree. BH are usually asymptomatic, but in rare cases they can be associated with jaundice, heartburn and fever. Read More

Sheathless CE-MS based metabolic profiling of kidney tissue section samples from a mouse model of Polycystic Kidney Disease.

Sci Rep 2019 Jan 28;9(1):806. Epub 2019 Jan 28.

Center for Proteomics and Metabolomics, Leiden University Medical Center, Leiden, The Netherlands.

Capillary electrophoresis-mass spectrometry (CE-MS) using a sheathless porous tip interface emerged as an attractive tool in metabolomics thanks to its numerous advantages. One of the main advantages compared to the classical co-axial sheath liquid interface is the increased sensitivity, while maintaining the inherent properties of CE, such as a high separation efficiency and low sample consumption. Specially, the ability to perform nanoliter-based injections from only a few microliters of material in the sample vial makes sheathless CE-MS a well-suited and unique approach for highly sensitive metabolic profiling of limited sample amounts.

Department of Internal Medicine, School of Medicine, College of Medicine, Taipei Medical University, Taipei, Taiwan R.O.C; Division of Nephrology, Department of Internal Medicine, Taipei Medical University-Shuang Ho Hospital, New Taipei City, Taiwan. Electronic address:

Objective: Iron supplementation and erythropoietin stimulating agents (ESAs) are essential for maintaining hemoglobin levels in hemodialysis patients. However, patients with autosomal-dominant polycystic kidney disease (PKD) have higher endogenous erythropoietin levels, so their recommended iron indices for hemodialysis patients may differ. This study evaluated iron profiles, including ferritin levels and transferrin saturation (TSAT) to identify factors affecting mortality in patients on dialysis, and those associated with mortality in patients with and without PKD.

Identifying patient-important outcomes in polycystic kidney disease: an international nominal group technique study.

Nephrology (Carlton) 2019 Jan 20. Epub 2019 Jan 20.

Sydney School of Public Health, The University of Sydney, Sydney, Australia.

Aim: Patients with autosomal dominant polycystic kidney disease (ADPKD) are at increased risk of premature mortality, morbidities and complications, which severely impair quality of life. However, patient-centred outcomes are not consistently reported in trials in ADPKD, which can limit shared decision-making. We aimed to identify outcomes important to patients and caregivers and the reasons for their priorities. Read More

Biochem Biophys Rep 2019 Mar 11;17:169-176. Epub 2019 Jan 11.

Department of Veterinary Pharmacology, University of Miyazaki, Miyazaki 889-2192, Japan.

Aquaporin-11 (AQP11) is an intracellular AQP. Several studies with mice have shown that AQP11 has a role in normal development of the kidney after birth. Our previous studies have suggested that alteration of oxygen homeostasis may be involved in the kidney injury caused by AQP11 deficiency, although the underlying mechanism is largely unknown.

Aquaporins in Renal Diseases.

Int J Mol Sci 2019 Jan 16;20(2). Epub 2019 Jan 16.

State Key Laboratory of Natural and Biomimetic Drugs, Department of Pharmacology, School of Basic Medical Sciences, Peking University, Beijing 100038, China.

Aquaporins (AQPs) are a family of highly selective transmembrane channels that mainly transport water across the cell and some facilitate low-molecular-weight solutes. Eight AQPs, including AQP1, AQP2, AQP3, AQP4, AQP5, AQP6, AQP7, and AQP11, are expressed in different segments and various cells in the kidney to maintain normal urine concentration function. AQP2 is critical in regulating urine concentrating ability. Read More

Genetics of polycystic liver diseases.

Curr Opin Gastroenterol 2019 Mar;35(2):65-72

Department of Gastroenterology and Hepatology, Radboud Institute for Molecular Life Sciences, Radboud University Medical Centre, Nijmegen, The Netherlands.

Purpose Of Review: This review provides an outline of the most recent insights and significant discoveries regarding the genetic mechanisms involved in polycystic liver disease.

Recent Findings: Polycystic liver disease includes a heterogeneous group of genetic disorders characterized by multiple hepatic cysts. Isolated liver cysts are caused by mutations in Protein Kinase C Substrate 80K-H (PRKCSH), SEC63, and LDL Receptor Related Protein 5 (LRP5), whereas Polycystic Kidney Disease (PKD)1, PKD2, and PKHD1 mutations cause kidney cysts often accompanied by liver cysts.

Inhibition of 5-Lipoxygenase Decreases Renal Fibrosis and Progression of Chronic Kidney Disease.

Am J Physiol Renal Physiol 2019 Jan 16. Epub 2019 Jan 16.

Medicine, University of Colorado, United States.

In inflammatory diseases, the 5-lipoxygenase (5-LO) pathway contributes to epithelial damage and fibrosis by catalyzing the production of leukotrienes. Antagonists of the 5-LO pathway are currently approved for use in patients and are well tolerated. We found that expression of 5-LO is strongly induced in three models of chronic kidney disease, unilateral ureteral obstruction (UUO), folate nephropathy, and an orthologous mouse model of polycystic kidney disease.

Autosomal Dominant Polycystic Kidney Disease: Presence of Hypomorphic Alleles in Gene.

Indian J Nephrol 2018 Nov-Dec;28(6):482-484

Molecular Genetics Laboratory, Institute of Medical Genetics and Genomics, Sir Ganga Ram Hospital, New Delhi, India.

Autosomal dominant polycystic kidney disease is characterized by multiple cysts in both kidneys manifesting in adult life. In general, the disorder is caused by a pathogenic variant in one allele of or genes, while the other allele is normal. Pathogenic variants in both the alleles are rare and have variable phenotypes, from lethal or perinatal presentation to a mild form in later adulthood, depending on the type of variant. Read More

A successful surgical repair of intraoperative pneumothorax and the diffuse dissection of visceral pleura during liver transplantation surgery via trans-diaphragmatic approach.

Surg Case Rep 2019 Jan 14;5(1). Epub 2019 Jan 14.

Department of Thoracic Surgery, Tokyo Women's Medical University, 8-1, Kawada-cho, Shinjuku-ku, Tokyo, 162-8666, Japan.

Background: Pneumothorax during surgery under general anesthesia is a life-threatening situation for the patient because it can progress easily to the tension pneumothorax due to positive pressure ventilation unless appropriate treatments such as inserting a drainage tube in the thoracic cavity are initiated. The authors experienced a case of intraoperative pneumothorax and the diffuse dissection of visceral pleura during liver transplantation surgery, and achieved successful repair by a trans-diaphragmatic approach without changing patient's body position.

Case Presentation: A 66-year-old male with multiple liver and renal cysts caused by autosomal dominant polycystic kidney disease (ADPKD) was admitted to the authors' hospital for treating the infection of the liver cysts. Read More

Bilateral renal artery stenosis as a cause of refractory intradialytic hypertension in a patient with end stage renal disease.

BMC Nephrol 2019 Jan 14;20(1):19. Epub 2019 Jan 14.

Section of Nephrology, Department of Medicine, Regina General Hospital, 1440, 14th Avenue, Regina, S4P 0W5, Canada.

Background: We report a 61-year-old female with end-stage renal disease (ESRD) secondary to polycystic kidney disease (PKD) complicated by intradialytic hypertension (IDH). Increased sympathetic drive leading to increased stroke volume and/or vasoconstriction with an inappropriate increase in peripheral vascular resistance (PVR) has been postulated to be the cause of IDH.

Case Presentation: Attempts to control her blood pressure by reducing her goal weight; increasing dialysis times/ frequency and decreasing her sodium concentrate in the dialysis fluid were unsuccessful. Read More
