[Lipid peroxidation in pneumonia of bacterial and viral etiologies].
The blood prooxidant and antioxidant systems were studied in 165 patients with pneumonia of bacterial and viral etiologies over time. There was a regular and significant increase in the levels of malondialdehyde, spontaneous nitroblue tetrasolium test, and catalase in the red blood cells; in parallel to this, there was ceruloplasmin activity suppression that depended on etiology, stage, and severity. Much pronounced and long-term impairments of the activity and level of prooxidant and antioxidant indices were suggestive of a severer clinical course and the presence of complications and concomitant diseases of infectious and inflammatory nature.
