PURPOSE OF THE STUDY
To analyze changes in blood biochemical parameters in the acute period of COVID-19, in the period of early and late convalescence during dynamic observation of patients.
MATERIAL AND METHODS
In 50 patients in the acute period of COVID-19 and in the post-COVID period, the content of glucose, creatinine, urea, total protein, albumin, total bilirubin, transaminases, C-reactive protein in the blood serum was studied.
RESULTS
In the acute period of COVID-19 and in the post-COVID period, cases of hyperglycemia were recorded (n=7 and n=6, respectively), not associated with a history of diabetes mellitus. During COVID-19, creatinine levels increased in almost every fourth patient and returned to normal in most patients during the convalescence period. Increased activity of transaminases during the illness was recorded in 64% of patients, in most patients in the post-COVID period, the indicators returned to normal. During hospitalization, an increased content of total bilirubin was determined in 1 patient, after 10—14 days — in 14% of patients, during the period of convalescence — in 6%. The course of the disease was characterized by hypoalbuminemia and a decrease in the concentration of total protein by 19%. In the period of convalescence, an increase in the concentration of total protein by 10% was recorded; a year after the infection, normalization of the albumin level was noted. The course of COVID-19 was accompanied by a significant increase in the level of C-reactive protein, which decreased in the dynamics of observations; after 2—3 months, the increase in the level remained in 12%, after a year — in 16% of patients.
CONCLUSION
The acute period of COVID-19 was characterized by pronounced changes in the biochemical parameters of the blood. In the post-COVID period, deviations from the norm of certain indicators were noted in more than 30% of patients. This indicates the need for dynamic monitoring of laboratory parameters, which can help prevent the development of comorbidities after suffering COVID-19.
