OBJECTIVE: To identify the likelihood of developing systemic inflammation (SI) as a general pathological process in severe haemorrhagic intracerebral stroke with and without the phenomenon of ineffective cerebral blood flow.
MATERIAL AND METHOD: Three groups were examined: 1) 89 blood donors (controls), 2) 15 patients with severe haemorrhagic stroke without the phenomenon of ineffective brain blood flow; 3) 26 patients with severe haemorrhagic stroke with ineffective cerebral blood flow. Ineffective cerebral blood circulation was recorded on the basis of transcranial Doppler ultrasound data; 87% of patients had clinical signs of brain death. All patients in the groups with haemorrhagic stroke had signs of multiple organ dysfunction according to the Sepsis-related Organ Failure scale, all of them received intensive care. An integrated scale based on the determination of plasma concentrations of cytokines (IL-6, IL-8, IL-10, TNF-α), procalcitonin, cortisol, D-dimers, myoglobin, troponin I was used to verify systemic inflammation.
RESULTS AND CONCLUSION: Systemic inflammation or borderline state (pre-SI) was identified in all patients of the second group both on 1-3 days from the onset of haemorrhagic stroke, and on 5-8 days. On the contrary, in the third group, there were no signs of SI on 1-3 days. On 5-8 days, signs of SI and pre-SI were recorded only in 18.2% of patients. Apparently, the reason for these differences is the blockade of the passage of tissue decay products and other pro-inflammatory factors into the bloodstream from the damaged brain in the third group.
