WHAT’S NEW
Novel biomarkers are needed in the prognosis and treatment process of the disease. There has been no report about thiol levels in pulmonary thromboembolism patients, so far. To our knowledge, this study is the first study that investigates thiols and thiol/disulphide homeostasis in patients with pulmonary thromboembolism (with subgroups). For this purpose, determination of dynamic thiol/disulphide status in diseases where oxidative stress plays a major role in pathogenesis would be important.
