[Cardiolipin antibodies in patients with myocardial infarction and unstable angina pectoris].

The clinical value of IgG and IgM cardiolipin antibodies (CLa) was examined in 22 patients with myocardial infarction and 9 patients with unstable angina (UA). Higher IgG levels were observed in 41% of MI patients and 55% of UA patients. There was a significant correlation between the detection of IgG CLa in patients with a history of myocardial infarction and the presence of left ventricular intracavitary thrombosis.

[Cardiolipin antibodies in acute rheumatic fever].

The paper presented the results obtained in studying the patients with acute rheumatic fever for antibodies to cardiolipin (ACL). The study resulted in the establishment that the development of immunopathies in the presence of acute rheumatic fever combined with the acute streptococcal infection was accompanied by hyperproduction of ACL (more common IgG versus IgM isotypes). The phenomenon mentioned widened the spectrum of acute infectious diseases associated with an increase in ACL synthesis.

[Cryoglobulinemia and fibronectin in systemic lupus erythematosus].

EIA was used to measure the concentration of fibronectin in plasma and cryoprecipitates of 37 patients suffering from systemic lupus erythematosus coupled with cryoglobulinemia. A definite relationship was discovered between the level of cryoglobulins and the activity of SLE, the concentration of fibronectin in plasma and liver damage. A tendency was revealed towards increase of the fibronectin content in plasma of patients with a high level of antibodies to native DNA and CIC as was a significant correlation between the concentration of cryoglobulin protein and the concentration of fibronectin in cryoprecipitates.
