Hypercoagulation in glomerulonephritis.
نویسندگان
چکیده
The clotting values of 50 patients with glomerulonephritis were examined. Three different coagulation groups were recognised: those with normal clotting values (group 1); those with high concentrations of factor VIII but otherwise normal clotting results (group 2); and patients who showed the presence of an activator of the intrinsic coagulation pathway, indicated by the presence of a short activated partial thromboplastin time or the ability of patients' plasma to shorten control clotting time in mixing studies (group 3). Patients in group 2 either had a uniform rise in all three components of the factor VIII molecule or a disproportionately higher concentration of factor-VIII-related antigen. In contrast, the level of VIII clotting activity in patients in group 3 was always higher than concentrations of either VIIIAg or VIIIWF. A significantly high incidence of thrombotic complications was observed in patients with group 3 but in none of the patients in either group 1 or group 2. Impaired renal function was more common in patients in groups 2 and 3, with higher mean serum creatinine concentrations in those with group 3. Patients with glomerulonephritis who have a short partial thromboplastin time with kaolin or who shorten control clotting time form a subgroup in whom hypercoagulation could adversely affect the course of their disease. The value of antiplatelet or anticoagulant treatment in these patients needs to be explored.

Anderson-Fabry disease is a rare inherited X-linked lysosomal storage disease caused by deficiency of the enzyme alpha-galactosidase A. Hereby we report a 39 year old male that presented with proteinuria and edema.

Despite the increased risk of thrombosis in cancer patients compared with healthy individuals, mechanisms that regulate cancer-induced hypercoagulation are incompletely understood. The aim of this study was to investigate whether cell-specific hypoxia-inducible factor (HIF) 1α regulates cancer-associated hypercoagulation, using in vitro clotting assays and in vivo cancer models. In mouse lung a...

Background: Nephrotic syndrome and type 1 diabetes mellitus are two common chronic conditions in children. Co-existence of these conditions is an extremely rare finding. Case presentation: This report presents a 6-year-old boy who was diagnosed with nephrotic syndrome five years ago and type 1 diabetes mellitus in infancy. Renal biopsy showed membranous glomerulonephritis, which is a rare h...

Thrombosis is a deadly malfunctioning of the hemostatic system occurring in numerous conditions and states, from surgery and pregnancy to cancer, sepsis and infarction. Despite availability of antithrombotic agents and vast clinical experience justifying their use, thrombosis is still responsible for a lion's share of mortality and morbidity in the modern world. One of the key reasons behind th...
