A novel therapy concept based on a removal of circulating BSP (bone sialoprotein) from the plasma of patients with chronic kidney disease (CKD) or highly at risk of developing arterial and vascular calcifications. The method comprises method of treatment of extracellular tissue and vascular calcifications, atherosclerosis, arteriosclerosis, and arterial calcification. The beneficial effects of this therapy have been proven by the observed correspondence between levels of circulating free BSP levels and mortality of CKD patients as well as in animal models.

Method of treating extracellular tissue and vascular calcification and arteriosclerosis

A new method of in vitro monitoring and assessing the need of a medication which interferes with the regulation of the parathyroid hormone level in a kidney patient subject to oxidative stress, notably hemodialysis patients. FIG.shows the distribution of n-oxPTH concentrations in 340 hemodialysis patients (224 men and 116 women) with a median age of 66 years (IQR, 56 to 75 years), a median time since initiation of dialysis (dialysis vintage) of 266 days (IQR, 31 to 1209 days), and a median dialysis dose (kt/V) of 1.2 (IQR, 1.1 to 1.3). The cause of chronic kidney disease was nephrosclerosis in 113 cases (33%), diabetic nephropathy in 107 cases (31%), chronic glomerular nephritis in 29 cases (9%), polycystic kidney disease in 9 cases (3%) and other/unknown in 82 cases (24%). The median n-oxPTH concentration was 5.9 ng/L (IQR, 2.4 to 14.0 ng/L). n-oxPTH concentrations were not different in men and women (5.9 ng/L; IQR, 2.4 to 14.2 ng/L; n=224; vs. 5.5 ng/L; IQR, 2.4 to 14.0 ng/L; n=116; p=0.915).

Non-oxidized, biological active parathyroid hormone determines mortality in hemodialysis patients

A method is disclosed for obtaining an antibody or antibody fragment to a conformational epitope specific for misfolded inactive human parathyroid hormone and fragments thereof. The method includes the steps of a) immunizing an animal with an immunogen which comprises oxidized parathyroid hormone or an oxidized fragment of parathyroid hormone, or both; and b) recovering an antibody, antibody fragments, or single chain antibody. The complementary determining region of the recovered antibody, antibody fragment or single chain antibody is capable of specifically recognizing a conformational epitope (antigenic determinant) which is present on oxidized parathyroid hormone and fragments thereof only but not regular bioactive human parathyroid hormone.

Means and methods of measuring parathyroid hormone in patients suffering from oxidative stress

The present invention provides a novel therapy concept based on a removal of circulation BSP (bone sialoprotein) from the plasma of patients with chronic kidney disease (CKD), preferably by plasmapheresis or an administration of antibodies against BSP in plasma. The present invention further provides a BSP absorber material for plasmapheresis and a pharmaceutical composition namely in form of anti-BSP antibodies for direct administration which are biocompatible in humans. The beneficial effects of this therapy have been proven by the observed correspondence between levels of circulating free BSP levels and mortality of CKD patients.

Medicament and apparatus for treating chronic kidney disease

Method of diagnosis and prognosis of contrast media induced nephropathy (CIN) including the steps of i) taking a urine sample from a patient exposed to the application of contrast media, notably patients subjected to coronary angiography; ii) assessing the level of vitamin D binding protein (VDBP) in the urine sample obtained in step (i); iii) relating the urinary vitamin D binding protein level determined in step (ii) to a pre-selected threshold level. A urinary vitamin D binding protein level higher than the pre-selected threshold level indicates that the patient is at risk of renal failure and in need of a dialysis treatment.

In vitro diagnostic and prognosis of major adverse events in patients undergoing coronary angiography

The present invention relates to methods for treating and/or preventing podocytes related disorders and/or nephrotic syndrome comprising the administration of an effective amount of a certain DPP-4 inhibitor, as well as to the use of a certain DPP-4 inhibitor for treating and/or preventing a metabolic disease in a patient with or at risk of podocytes related disorders and/or nephrotic syndrome.
