Aim of the study. To evaluate the risk factors for the occurrence of intramuscular hematomas in patients with severe coronavirus infection receiving anticoagulant therapy.Materials and methods. Intramuscular hematomas in five patients with severe COVID-19 disease are reported in the paper. The criteria for selecting patients for the study included respiratory distress requiring oxygen, radiographic signs of severe pneumonia, anticoagulant therapy using low molecular weight heparin (LMWH), and spontaneous intramuscular hematoma. Clinical manifestations, blood coagulation results, conservative and surgical management were analyzed.Results. Standard regimen anticoagulation therapy in patients with coronavirus infection requires vigilance because of a risk of development of hemorrhagic complications.Сonclusion. When assessing a patient with hematomas, an emphasis should be given to examination of patients and changes in hemoglobin and hematocrit levels. Best strategy of anticoagulant therapy for patients with coronavirus infection and high risk of VTE, as well as optimal laboratory monitoring during LMWH administration are yet to be explored.

Patients with chronic disorders of consciousness (CDoC) have various variants of the pathological organization of functions including sympathetic hyperactivity and hormonal changes.The objective: to determine the severity of paroxysmal sympathetic hyperactivity (PSH), the function of the pituitary-adrenal system in patients with CDoC.Subjects and Methods. 54 patients with CDoC were enrolled in the study. Patients were randomized in the groups depending on assessment on the Coma Recovery Scale-Revised scale and CRS-R index calculation. PSH severity was assessed 7 times a day for two days. During the first week from the moment of admission, blood sampling was performed 7 times a day to study the levels of ACTH and cortisol.Results. PSH syndrome was detected in all groups, there were no significant dependencies of its severity on the time of day. There were no significant differences in the levels of ACTH and cortisol during the day.Conclusions: PSH syndrome is observed in most patients with CDoC. In patients with CDoC, the daily rhythm of ACTH and cortisol secretion are disrupted.
