The fetal proteins in prognosis of development of pneumonia in patients with ischemic stroke

The searching of laboratory predictors of pneumonia inpatients with ischemic stroke is an actual issue. The fetal proteins can be such biomarkers. The study was carried out to determine significance of such fetal proteins as alpha-fetoprotein, cancerous embryonic antigen, CA 19-9, CA 125, CA 15-3, CA 72-4, CYFRA 21-1 for prognosis of development of pneumonia in patients with ischemic stroke. The study included sampling of 216 patients in acute period of ischemic stroke. All patients were measured level of fetal proteins in first day from onset of disease using electrochemiluminescence immunoassay. It is demonstrated that CA 72-4 has the most significance for prognosis of development of pneumonia from all analyzed proteins and complications of ischemic stroke. The probability ratio relatively to other fetal proteins added up to 0.460 (CL 95% 0.267-0.791, p=0.011), to other complications - 0.629 (CL 95% 0.433-0.913, p=0.015). The threshold value of CA 72-4 for development of pneumonia added up to 0.82 (CL 95% 0.68-0.96, p=0.01l) U/ml. Under lower level of CA 72-4 the risk of development of pneumonia increases. Under higher level of CA 72-4thereis statistical probability of absence of development of pneumonia. The threshold value was lower than reference interval which in the study added up to 0.85-1.42 U/ml. The detection of level of CA 72-4 on first day after onset of stroke in patients can be recommended for establishing of group of high risk of development of pneumonia and implementation of therapeutic activities.
