Therapeutic Use of mTOR Inhibitors in Renal Diseases: Advances, Drawbacks, and Challenges.

Oxid Med Cell Longev 2018 29;2018:3693625. Epub 2018 Oct 29.

Laboratory of Pharmacology & Experimental Therapeutics, Coimbra Institute for Clinical and Biomedical Research (iCBR), Faculty of Medicine, CNC.IBILI Consortium & CIBB Consortium, University of Coimbra, 3000-548 Coimbra, Portugal.

The mammalian (or mechanistic) target of rapamycin (mTOR) pathway has a key role in the regulation of a variety of biological processes pivotal for cellular life, aging, and death. Impaired activity of mTOR complexes (mTORC1/mTORC2), particularly mTORC1 overactivation, has been implicated in a plethora of age-related disorders, including human renal diseases. Since the discovery of rapamycin (or sirolimus), more than four decades ago, advances in our understanding of how mTOR participates in renal physiological and pathological mechanisms have grown exponentially, due to both preclinical studies in animal models with genetic modification of some mTOR components as well as due to evidence coming from the clinical experience.

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.

Hum Reprod 2018 Nov 24. Epub 2018 Nov 24.

University of Paris-Sud and University Paris-Saclay, Le Kremlin-Bicêtre, France.

Study Question: Does the phenotype of women with normosmic congenital hypogonadotrophic hypogonadism (nCHH) and pituitary resistance to GnRH caused by biallelic mutations in the GnRH receptor (GNRHR) (nCHH/bi-GNRHR) differ from that of women with polycystic ovary syndrome (PCOS)?

Summary Answer: Women with nCHH/bi-GNRHR have variable pubertal development but nearly all have primary amenorrhea and an exaggerated LH response to GnRH stimulation, similar to that seen in women with PCOS.

What Is Known Already: Women with nCHH/bi-GNRHR are very rare and their phenotype at diagnosis is not always adequately documented. The results of gonadotrophin stimulation by acute GnRH challenge test and ovarian features have not been directly compared between these patients and women with PCOS. Read More

Moderate increases in daily step count are associated with reduced IL-6 and CRP in women with PCOS.

Endocr Connect 2018 Nov 1. Epub 2018 Nov 1.

M Davies, Diabetes Research Centre, University of Leicester College of Medicine Biological Sciences and Psychology, Leicester, United Kingdom of Great Britain and Northern Ireland.

Aims: Physical activity has been proposed to be an effective non-pharmacological method of reducing systemic inflammation and therefore may prove particularly efficacious for women with polycystic ovary syndrome (PCOS) who have been shown to have high levels of inflammation and an increased risk of type 2 diabetes (T2DM) and cardiovascular disease (CVD). Therefore the aim of the present study was to assess whether modest changes daily step count could significantly reduce levels of inflammatory markers in women with PCOS.

Subjects And Methods: Sixty five women with PCOS were assessed at baseline and again at 6 months. Read More

Utility of HbA assessment in people with diabetes awaiting liver transplantation.

Diabet Med 2018 Nov 26. Epub 2018 Nov 26.

Medical School, University of Birmingham, Birmingham.

Aims: To investigate the relationship between HbA and glucose in people with co-existing liver disease and diabetes awaiting transplant, and in those with diabetes but no liver disease.

Methods: HbA and random plasma glucose data were collected for 125 people with diabetes without liver disease and for 29 people awaiting liver transplant with diabetes and cirrhosis. The median (interquartile range) Model for End Stage Liver Disease score for the study cohort was calculated as 12 (9-17; normal <6). Read More

Urinary Level of Liver-Type Fatty Acid Binding Protein Reflects the Degree of Tubulointerstitial Damage in Polycystic Kidney Disease.

Kidney Blood Press Res 2018 Nov 23;43(6):1716-1729. Epub 2018 Nov 23.

Division of Nephrology and Hypertension, Department of Internal Medicine, St. Marianna University School of Medicine, Kanagawa,

Background/aims: Polycystic kidney disease (PKD) is a common, progressive, and heritable type of kidney disease. Although certain imaging modalities are useful for the diagnosis and staging of PKD, they cannot adequately monitor the severity of interstitial inflammation and fibrosis. Therefore, the present study evaluated the urinary level of liver-type fatty acid binding protein (L-FABP) as a marker of interstitial inflammation and fibrosis in PKD. Read More

Folate-dactolisib conjugates for targeting tubular cells in polycystic kidneys.

J Control Release 2018 Nov 23;293:113-125. Epub 2018 Nov 23.

Department of Pharmaceutics, Utrecht Institute for Pharmaceutical Sciences, Utrecht University, Utrecht, The Netherlands. Electronic address:

The aim of the present study was to develop folic acid (FA) conjugates which can deliver the kinase inhibitor dactolisib to the kidneys via folate receptor-mediated uptake in tubular epithelial cells. Dactolisib is a dual inhibitor of phosphatidylinositol 3-kinase (PI3K) and mammalian target of rapamycin (mTOR) and is considered an attractive agent for treatment of polycystic kidney disease. The ethylenediamine platinum(II) linker, herein called Lx, was employed to couple dactolisib via coordination chemistry to thiol-containing FA-spacer adducts to yield FA-Lx-dactolisib conjugates.

Urinary 8-Hydroxy-2'-deoxyguanosine (8-OHdG) Concentrations and Menstrual Cycle Characteristics in Female University Students.

Int J Environ Res Public Health 2018 Nov 22;15(12). Epub 2018 Nov 22.

Faculty of Nursing, Tokyo Healthcare University, 2-5-1 Higashigaoka, Meguro, Tokyo 152-8558, Japan.

Higher concentrations of oxidative stress biomarkers are found in women with polycystic ovary syndrome (PCOS) and endometriosis, conditions linked to irregular menstrual cycles and menstrual pain. The aim of the present study was to test whether women with higher oxidative stress are more likely to show irregular menstrual cycles and severe menstrual pain compared with women with lower oxidative stress. A cross-sectional study was conducted targeting female university students with a mean (SD) age of 20. Read More
