Serum alpha-1-antitrypsin in ischemia and rheumatic heart diseases.
Tissue damage, inflammation and necrosis are hallmarks of myocardial infarction. In the present study significant elevations of serum alpha-1-antitrypsin were noted in coronary artery disease and angina cases. Interestingly chronic rheumatic heart disease which is also characterized by tissue injury. Inflammation revealed normal levels of serum alpha-1-antitrypsin. The level in chronic rheumatic heart disease was 3.37 +/- 0.57 mumol/mt/ml (control level was 3.37 +/- 0.54 mumol/mt/ml). The corollary of these observations is that in heart diseases acute phase response in terms of enhanced levels of alpha-1-antitrypsin differ depending on the causative factors. Except chronic rheumatic heart disease, in all other stressful states studied there is (to a certain degree) an altered systemic homeostasis and haemostasis. On the other hand chronic rheumatic heart disease encompass certain amount of acute phase status in terms of tissue damage and inflammation does exist unaccompanied by altered systemic homeostasis and haemostasis. However, bacteriological etiologies predominate the triggered immune responses. It is hypothesised that serum alpha-1-antitrypsin enhancement will not occur even though acute phase state exists if specific immune responses are also a part of the disease manifestation.
