[Plasmic activity of phospholipid membranes in nephritis].
OBJECTIVE
To study activity of plasmic phospholipid membranes (PPM) in patients with chronic nephritis (CN) as regards clinical-laboratory and morphological characteristics of the disease.


METHODS
10 patients with chronic mesangial glomerulonephritis (CMG) and 4 patients with chronic drug-induced tubulointerstitial nephritis were examined. All the patients had moderate arterial hypertension including 5 patients with CMG combined with nephrotic syndrome. 9 patients had elevated blood creatinine (up to 500 mcmol/l). Measurements were made of routine laboratory indices, blood coagulation and paracoagulation, Willebrand's factor (WF), aggregation time (AT), phospholipid activation of blood coagulation (FABC), morphological indices of activity and sclerosis.


RESULTS
In spite of chronic latent intravascular blood coagulation, CN was characterized by apparent lowering of FABC which was more evident in CMG. There was a weak correlation between a FABC fall and the level of proteinuria, lipidemia, AT of platelets, indices of activity. Some parallels exist between creatininemia and activity of PPM. A close reverse relationship was found between FABC and WF, and a direct one between FABC and sclerosis index.


CONCLUSIONS
Subnormal PPM activity in CN correlates with organic microthrombi formation and promotes the discussion of both mechanisms of FABC formation disturbances and possible ways of PPM consumption including enhanced diffusion into the mesangium in progressing nephrosclerosis.
