Asthenic syndrome in the convalescents of ixodid tick-borne borrelioses

Aim to study the catamnesis of patients with ixodid tick-borne borreliosis in the period of convalescence who presented the signs of asthenic syndrome. Material and methods. The study was based on the data of prospective dispensary observation of 37 in-patients diagnosed with "ixodid tick-borne borreliosis, erythemic form, moderate severity, acute course" who received treatment at the Clinic of Infectious Diseases of the SamSMU in 2016-2019. The subjects were divided into 3 groups according to their age: the first age-group from 18 to 35 years included 12 people, the second group ranged from 36 to 55 years and included 15 people, the third age-group from 56 to 75 years consisted of 10 people. The examination of patients was carried out after discharge from the hospital on the 14th day, after 3, 12 and 36 months. The MFI-20 asthenia scale (the Multidimensional Fatigue Inventory) was used to analyze the asthenic syndrome in the participants. Results. The duration of asthenia after ixodid tick-borne borreliosis may be up to 3 years. Patients require the closest observation in the first 2 weeks of the convalescence period. Indicators of physical and psychological health in convalescents return to the norm depending on their age and place of residence. Mental asthenia prevails in people living in rural areas and persists much longer than in urban residents. Older people (from 56 to 75 years) are more susceptible to general and physical asthenia.
