The aim of the study was to study the effect of convulsive syndrome in patients with delirium tremens (DT) on the charac teristics of the metabolic status of the body, the severity of clinical manifes tations, and survival of people of diff erent ages. The study involved 753 patients with DT at the age of 20 to 76 years. The metabolic status was studied. One indicator was the urea-creatinine serum index; its low level was considered a sign of anabolic trends in metabolism. Another indicator was the determination of the total protein content in the body by daily excretion of creatinine. It was found that patients with DT with convulsive syndrome had a higher score according to the severity of the disease according to the DRS scale, a longer period of mental disorders, the average number of somatic complications was higher. However, the survival rate of patients with DT with convulsive syndrome and patients with DT without convulsive manifestations was the same. To determine the causes of this, the metabolic status and age of surviving and deceased patients with DT were compared. The highest total protein content in the body is observed in surviving patients with DT with manifestations of convulsive syndrome. Surviving patients with DT with manifestations of convulsive syndrome had a signifi cantly lower level of urea-creatinine index compared with survivors with DT without convulsive syndrome. Among all patients with DT, the average age of survivors with convulsive syndrome was the lowest, and the average age of deceased patients with convulsive syndrome was the highest. In patients with DT without convulsive manifestations, the age of surviving and dead patients did not diff er. The age of surviving patients with DT with convulsive syndrome is signifi cantly lower than that of surviving patients without convulsive manifestations. The presence of convulsive syndrome and associated metabolic changes in the body in patients with DT contributes to the survival of a younger part of patients.
