Abstrakt: Objectives. To study the prevalence and clinical manifestations of postcovid syndrome (PCS) in out-patients and to assess the efficacy of treatment with the drug Cortexin at doses of 10 and 20 mg i.m. for 10 days. Materials and methods. A total of 979 patients with PCS from regions of the Russian Federation, Azerbaijan, Kyrgyzstan, and Kazakhstan were studied; mean age was 54.6 ± 4.5 years; duration of COVID-19 was from one month upwards. Investigations involved three visits. The first was on the day of consultation (assessment of complaints, analysis of scale indicators, prescription of drug Cortexin at a dose of 10 or 20 mg i.m. for 10 days). The second visit (telephone consultation) was on day 10-14. The third visit was on day 30 of out-patient treatment. Assessment of patients' status used an asthenia assessment scale (MFI-20), a brief mental state assessment scale (MMSE), the Schulte test, and the Subjective Treatment Quality Assessment Scale. Results. The proportion of patients with PCS was up to 30% of all neurological admissions. The commonest manifestations were: fatigue, general weakness, decreased memory and concentration of attention, vertigo, sleep impairment, irritability, and aggression; less frequent were breathlessness, pain, increased sweating, anosmia, hyposmia, dysgeusia, paresthesia, hair loss, degradation of vision, tachycardia, allergic reactions, menstrual cycle impairments, erectile dysfunction, panic attacks, suicidal ideation, depression and refusal to eat meat. Conclusions: No associations were found between clinical symptomatology and the severity of COVID-19, the volume of lung tissue affected, or different periods of postcovid syndrome. Cortexin was found to be effective at doses of 10 and 20 mg for correcting the cognitive and asthenic manifestations of PCS. Cortexin was found to have anti-anxiety, antidepressant, and anxiolytic effects, which were more marked at the 20-mg dose.
