Twin pregnancy in a patient on chronic haemodialysis who already had three pregnancies.

Pregnancy in women with end-stage renal disease is rare. Multiple pregnancies carry a high risk of complications even in healthy individuals. We report the case of a 36-year-old woman who had four pregnancies while she was on dialysis, including one twin pregnancy.

Identification of novel antilipogenic agents targeting fatty acid biosynthesis through structure-based virtual screening.

An Asinex Gold Platinium chemical library subset of 12 055 compounds was screened employing docking simulations in the active site of the human FAS KS domain. Among them, 13 compounds were further evaluated for their ability to inhibit fatty acid biosynthesis. Four compounds were found to be active in particular ASN05064661 and ASN05374526 with IC50 values of 6.

[A giant cell arteritis revealing a Goodpasture's syndrome].

Goodpasture's syndrome is a triad of anti-glomerular basement membrane (anti-GBM) circulating antibodies, glomerulonephritis and pulmonary hemorrhage. We reported a 65-year-old woman with headaches, asthenia and weight loss. Giant cell arteritis was confirmed by temporal artery biopsy.

p-Cresyl glucuronide is a major metabolite of p-cresol in mouse: in contrast to p-cresyl sulphate, p-cresyl glucuronide fails to promote insulin resistance.

Background: The role of uraemic toxins in insulin resistance associated with chronic kidney disease (CKD) is gaining interest. p-Cresol has been defined as the intestinally generated precursor of the prototype protein-bound uraemic toxins p-cresyl sulphate (p-CS) as the main metabolite and, at a markedly lower concentration in humans, p-cresyl glucuronide (p-CG). The objective of the present study was to evaluate the metabolism of p-cresol in mice and to decipher the potential role of both conjugates of p-cresol on glucose metabolism.

The relationship between renal function and plasma concentration of the cachectic factor zinc-alpha2-glycoprotein (ZAG) in adult patients with chronic kidney disease.

Zinc-α2-glycoprotein (ZAG), a potent cachectic factor, is increased in patients undergoing maintenance dialysis. However, there is no data for patients before initiation of renal replacement therapy. The purpose of the present study was to assess the relationship between plasma ZAG concentration and renal function in patients with a large range of glomerular filtration rate (GFR).

Leptin as an uremic toxin: Deleterious role of leptin in chronic kidney disease.

White adipose tissue secretes a large variety of compounds named adipokines amongst which, leptin exhibits pleiotropic metabolic actions. Leptin is an anorexigenic hormone, secreted in proportion of fat mass, with additional effects on the regulation of inflammation, cardiovascular system, immunity, hematopoiesis and bone metabolism. Chronic kidney disease (CKD) is characterized by an increase of plasma leptin concentration that may be explained by a lack of renal clearance.

Insulin resistance in chronic kidney disease: new lessons from experimental models.

Insulin resistance (IR) is a common feature of chronic kidney disease (CKD), but the underlying mechanisms still remain unclear. A growing body of evidence suggests that IR and its associated metabolic disorders are important contributors for the cardiovascular burden of these patients. In recent years, the modification of the intestinal flora and activation of inflammation pathways have been implicated in the pathogenesis of IR in obese and diabetic patients.

Ectopic lipid accumulation: A potential cause for metabolic disturbances and a contributor to the alteration of kidney function.

Ectopic lipid accumulation is now known to be a mechanism that contributes to organ injury in the context of metabolic diseases. In muscle and liver, accumulation of lipids impairs insulin signaling. This hypothesis accounts for the mechanism of insulin resistance in obesity, type 2 diabetes, aging and lipodystrophy.
