Vascular calcification in continuous ambulatory peritoneal dialysis patients.

Vascular calcifications represent a severe complication of secondary hyperparathyroidism in patients with chronic kidney disease (CKD) stage 5. The factors influencing the development of this complication are in close relation with the pathology of chronic dialysis premorbid condition, and with therapy as well. The present article highlights the association between several factors and the development or the aggravation of vascular calcifications in continuous ambulatory peritoneal dialysis (CAPD) patients.

Vascular calcifications in chronic kidney disease--clinical management.

Chronic kidney disease (CKD) patients could present various types of calcifications causing different pathological conditions that would contribute to the renal disease progression and high risk of mortality. Extra-skeletal calcifications represent a common consequence of mineral bone disorders in CKD patients. Vascular calcifications represent a complex systemic manifestation caused by phospho-calcium homeostasis disorders, by imbalance among promoters and inhibitors of calcification and the presence of various arterial diseases and other risk factors.

In vivo experimental model for the study of the influence of subinhibitory concentrations of phenyllactic acid on Staphylococcus aureus pathogenicity.

The discovery of communication systems regulating bacterial virulence has afforded a novel opportunity to control infectious bacteria without interfering with their growth. In this paper the authors describe the effect of subinhibitory concentrations of phenyl-lactic acid (PLA) on the pathogenicity of Staphylococcus aureus in holoxenic mice. The animals were inoculated by oral (p.
