Study: Food Restriction Prevents and Reverses Polycystic Kidney Disease in Mice

https://www.youtube.com/watch?v=PR6klhuVeyw ROCHESTER, Minn. — Researchers at Mayo Clinic have found that a mild to moderate reduction in calories effectively prevents and reverses polycystic kidney disease (PKD) in mice. The results appear online today in the Journal of the American Society of Nephrology. “Currently, there is no FDA-approved treatment, and the only thing that can be done [...]

CONCLUSIONS Thrombocyte level was positively correlated with eGFR but was not associated with presence of PKD-related symptoms, suggesting thrombocyte level might be an independent serum biomarker for disease progression. Hypertension was associated with increased risk of symptom occurrence, indicating the relationship between hypertension and disease progression. This study reveals the clinical characteristics of inpatients with ADPKD in China and provides clinicians with useful insights into this intractable disease. PMID: 30219820 [PubMed - in process]

We report the case of a 35-year-old female Moroccan patient with the diagnosis of ADPKD associated with arterial hypertension who came into the Emergency Department with lower abdominal pain lasting for five days being diagnosed as salpingitis. Abdominal computed tomography scan with contrast showed both kidneys with several cystic images with a thin wall. A transthoracic echocardiogram revealed the presence of moderate PE more in the anterior aspect. A greater set of standard tests to rule out collagen vascular disease, rheumatoid diseases, autoimmune disorders, and malignancies was ordered. These tests yielded no abnorma...

Authors: Scarioti VD, Oliveira LT, Mattiello AC, Gomes NDS Abstract A 16-year-old female patient previously diagnosed with autosomal recessive polycystic kidney disease (ARPKD) presented with acute bilateral pneumonia, upper gastrointestinal bleeding caused by ruptured esophageal varices, ascites, and lower limb edema. She required intensive care and an endoscopic procedure to treat the gastrointestinal bleeding. The analysis of the differential diagnosis for chronic liver disease indicated she had a spontaneous splenorenal shunt. Ultrasound-guided biopsy revealed the patient had cirrhosis, as characteristically se...

ConclusionsWe found all ARPKD cases withoutPKHD1 point mutations to be phenocopies, and none to be explained by biallelicPKHD1 copy number variations. Screening for copy number variations is recommended in patients with a heterozygous point mutation.

Mutations in two genes, PKD1 and PKD2, account for most cases of autosomal dominant polycystic kidney disease, one of the most common monogenetic disorders. Here we report the 3.6-angstrom cryo–electron microscopy structure of truncated human PKD1-PKD2 complex assembled in a 1:3 ratio. PKD1 contains a voltage-gated ion channel (VGIC) fold that interacts with PKD2 to form the domain-swapped, yet noncanonical, transient receptor potential (TRP) channel architecture. The S6 helix in PKD1 is broken in the middle, with the extracellular half, S6a, resembling pore helix 1 in a typical TRP channel. Three positively charged,...

Abstract Chronic kidney disease (CKD) includes all clinical features and complications during the progression of various kidney conditions towards end-stage renal disease (ESRD). These conditions include immune and inflammatory disease such as: primary and hepatitis C virus (HCV)-related glomerulonephritis; infectious disease such as pyelonephritis with or without reflux and tuberculosis; vascular disease such as chronic ischemic nephropathy; hereditary and congenital disease such as polycystic disease and congenital cystic dysplasia; metabolic disease including diabetes and hyperuricemia; and systemic disease (co...

ConclusionLymphangioma, although rare in the small bowel, is a possible cause of intussusception and should be considered on the differential of abdominal pain in adults. The pathogenesis of polycystic kidney disease has implications that could predispose to cystic development beyond the kidney, and more research into the genetic mechanism behind the disease is necessary to support or deny this claim.

CONCLUSION: PRCA is a rare condition among patients on dialysis treated with rhEPO and should be considered as a possible cause of refractory anemia. Treating patients with PRCA may be challenging, since the specific management and diagnostic procedures needed in this condition are not always readily available.

Conclusions Interactions between macrophages and CLECs promote cyst growth. ARG1 is a key molecule involved in this process and is a potential therapeutic target to help delay ADPKD progression.
