Hyperthyroidism in pregnancy: design and methodology of a Danish multicenter study.

Background: Graves' disease (GD) is the main cause of hyperthyroidism in women of the fertile age. In pregnant women, the disease should be carefully managed and controlled to prevent maternal and fetal complications. Observational studies provide evidence of the adverse effects of untreated hyperthyroidism in pregnancy and have in more recent years substantiated a risk of teratogenic side effects with the use of antithyroid drugs (ATDs).

[Metastasis from breast cancer to the pituitary gland causing hyponatriaemia].

Breast cancer is the most common cancer in Danish women. Pituitary metastases are rare events. We report a 75-year-old woman with metastatic breast cancer who presented with pituitary insufficiency nine years after her initial cancer diagnosis.

Renal effects of a neutralising RAGE-antibody in long-term streptozotocin-diabetic mice.

Advanced glycation endproducts (AGEs) have been implicated in the pathogenesis of diabetic kidney disease. The actions of AGEs are mediated both through a non-receptor mediated pathway and through specific receptors for AGEs (e.g.

A neutralizing VEGF antibody prevents glomerular hypertrophy in a model of obese type 2 diabetes, the Zucker diabetic fatty rat.

Background: Antagonism of vascular endothelial growth factor (VEGF) has improved the outcome in experimental nephropathies of various origins, including diabetic nephropathy in a type 1 diabetic rat model and a type 2 diabetic mouse model. Neutralizing VEGF antibodies prevented glomerular hypertrophy in these models. We examined the renal effects of VEGF blockade in an obese rat model of type 2 diabetic nephropathy and investigated the mechanism underlying the inhibition of glomerular hypertrophy.

Pathophysiological role of vascular endothelial growth factor in the remnant kidney.

Background: Subtotal renal ablation is characterized by initial glomerular hypertrophy, followed by progressive development of glomerulosclerosis and interstitial fibrosis. Vascular endothelial growth factor (VEGF) is involved in glomerular hypertrophy and dysfunction in several pathophysiological conditions. On the other hand, progressive glomerulosclerosis and tubulo-interstitial fibrosis in the remnant kidney have been associated with loss of VEGF expression.

Kidney growth in normal and diabetic mice is not affected by human insulin-like growth factor binding protein-1 administration.

Insulin-like growth factor I (IGF-I) accumulates in the kidney following the onset of diabetes, initiating diabetic renal hypertrophy. Increased renal IGF-I protein content, which is not reflected in messenger RNA (mRNA) levels, suggests that renal IGF-I accumulation is due to sequestration of circulating IGF-I rather than to local synthesis. It has been suggested that IGF-I is trapped in the kidney by IGF binding protein 1 (IGFBP-1).

From hyperglycemia to diabetic kidney disease: the role of metabolic, hemodynamic, intracellular factors and growth factors/cytokines.

At present, diabetic kidney disease affects about 15-25% of type 1 and 30-40% of type 2 diabetic patients. Several decades of extensive research has elucidated various pathways to be implicated in the development of diabetic kidney disease. This review focuses on the metabolic factors beyond blood glucose that are involved in the pathogenesis of diabetic kidney disease, i.

The role of vascular endothelial growth factor (VEGF) in renal pathophysiology.

Vascular endothelial growth factor (VEGF) is an endothelial-specific growth factor that promotes endothelial cell proliferation, differentiation and survival, mediates endothelium-dependent vasodilatation, induces microvascular hyperpermeability and participates in interstitial matrix remodeling. In the kidney, VEGF expression is most prominent in glomerular podocytes and in tubular epithelial cells, while VEGF receptors are mainly found on preglomerular, glomerular, and peritubular endothelial cells. The role of VEGF in normal renal physiology is essentially unknown.

Long-term renal changes in the Goto-Kakizaki rat, a model of lean type 2 diabetes.

Background: Type 2 diabetes has become the single most frequent cause of end-stage renal disease. The Goto-Kakizaki rat is currently used as a model for lean type 2 diabetes, but its renal changes have not been fully characterized. We investigated long-term functional and structural renal changes in the Goto-Kakizaki rat to evaluate if this animal model resembles the changes observed in human diabetic kidney disease.

Long-term renal effects of a neutralizing RAGE antibody in obese type 2 diabetic mice.

Advanced glycation end products (AGEs) have been implicated in the pathogenesis of diabetic kidney disease. The actions of AGEs are mediated both through a non-receptor-mediated pathway and through specific receptors for AGE (RAGEs). To explore a specific role for RAGE in renal changes in type 2 diabetes, we examined the renal effects of a neutralizing murine RAGE antibody in db/db mice, a model of obese type 2 diabetes.

The effect of growth hormone on the development of diabetic kidney disease in rats.

Background: Nephropathy is the most severe complication of diabetes mellitus. We investigated the effect of exogenous growth hormone (GH) administration on renal function and matrix deposition in the streptozotocin (STZ) model of type I-diabetic rat.

Methods: Adult female STZ-diabetic rats (D), non-diabetic control rats injected with saline (C) and control and diabetic rats injected with bovine GH for 3 months (CGH and DGH, respectively) were used.

Amelioration of long-term renal changes in obese type 2 diabetic mice by a neutralizing vascular endothelial growth factor antibody.

Diabetic nephropathy in type 2 diabetic patients is a frequent complication associated with increased morbidity and mortality. Various growth factors and cytokines have been implicated in the pathogenesis of diabetic kidney disease, including vascular endothelial growth factor (VEGF). To explore a role for VEGF in renal changes in type 2 diabetes, we examined the renal effects of a neutralizing murine VEGF antibody in the diabetic db/db mouse, a model of obese type 2 diabetes.

Compensatory glomerular growth after unilateral nephrectomy is VEGF dependent.

Various growth factors and cytokines have been implicated in different forms of kidney enlargement. Vascular endothelial growth factor (VEGF) is essential for normal renal development and plays a role in diabetic glomerular enlargement. To explore a possible role for VEGF in compensatory renal changes after uninephrectomy, we examined the effect of a neutralizing VEGF-antibody (VEGF-Ab) on glomerular volume and kidney weight in mice treated for 7 days.

High protein-induced glomerular hypertrophy is vascular endothelial growth factor-dependent.

Background: Various growth factors and cytokines have been implicated in different forms of kidney enlargement such as renal growth following induction of diabetes, unilateral nephrectomy, and exposure to high protein diet. Vascular endothelial growth factor (VEGF) is essential for normal renal development and plays a role in diabetes-associated renal and glomerular enlargement.

Methods: To elucidate a possible role for VEGF in high protein-induced renal/glomerular enlargement, we examined the effect of a neutralizing VEGF-antibody (VEGF-ab) on kidney weight and glomerular volume in mice fed a high protein diet for up to seven days.

Is folate a promising agent in the prevention and treatment of cardiovascular disease in patients with renal failure?

Management of the conventional cardiovascular risk factors is insufficient to prevent the dramatic increase in atherosclerotic cardiovascular morbidity and mortality in patients with renal failure. Folate recently received attention as a potential alternative treatment option to decrease the excess cardiovascular risk in the uremic population. Folate administration is the principal treatment modality for hyperhomocysteinemia.
