Serum anti-collagen type IV IgM antibodies and development of diabetic nephropathy in diabetics with essential hypertension.

Introduction And Aims: Arterial hypertension and diabetic vascular complications are connected with an elevated degradation of elastic tissue. This process leads to an increased production of antibodies to collagen type IV (ACIV Abs). In the present investigation we studied whether the serum levels of antibodies (IgG, IgM and IgA) to collagen are related with microvascular complications.

Abnormal levels of age-elastin derived peptides in sera of diabetic patients with arterial hypertension.

Introduction: An important factor in vascular wall alterations is degradation of elastic fiber major protein - elastin. As a result, elastin derived peptides (EDP) are found in circulation. Advanced glycation might also involve elastin, because it is a protein with slow metabolism.

Detection of elastin derived peptides in cerebrospinal fluid of patients with first ever ischaemic stroke.

Objective: We have previously reported the optimized methods for the detection of elastin derived peptides (EDP) in the serum, synovial fluid, and bronchoalveolar lavage. The aim of the present study was to investigate whether EDP are detectable in cerebrospinal fluid (CSF) of patients with acute brain ischaemia.

Patients And Methods: Twenty-seven first ever ischaemic stroke patients (mean age 61.

Increased levels of elastin-derived peptides in cerebrospinal fluid of patients with lacunar stroke.

Objective: To investigate whether elastin-derived peptides (EDP) are detectable in the cerebrospinal fluid (CSF) of healthy controls and of patients with acute brain ischemia and if so to assess possible trends in EDP levels in different groups of ischemic stroke patients (small-vessel disease vs. other ischemic strokes; first-ever vs. recurrent stroke).

Abnormal levels of serum antielastin antibodies in children with diabetes mellitus type 1.

Antibodies to alpha-elastin (elastin breakdown product) and elastin sequences devoid of cross-linked regions (linear elastin) are found in the serum of all human subjects and correlate with their respective serum peptide levels. The aim of this study was to determine if the serum level of antielastin antibodies (AEAbs) differs between type 1 diabetic children and nondiabetic children. Enzyme-linked immunosorbent assay was used to measure the levels of immunoglobulin (Ig)G and IgM AEAbs in the sera of 45 diabetic children (mean age 12.
