[Central sensitization and comorbid disorders in patients with coronary heart disease]. / Tsentral'naya sensitizatsiya i komorbidnye rasstroistva u patsientov s ishemicheskoi bolezn'yu serdtsa.

OBJECTIVE: Study of central sensitization (CS), insomnia and meteosensitivity in patients with coronary heart disease (CHD) admitted for a routine examination. MATERIAL AND METHODS: 67 patients (29 men and 38 women), aged 50-87 years, average age 73 [67; 85] years, with chronic forms of coronary heart disease were examined. The examination included the Russian version of the central sensitization inventory (CSI); assessment of meteosensitivity using a visual analogue scale (VAS); questionnaire for semi-quantitative assessment of subjective sleep characteristics (ASHS). Patients with the presence of CS were prescribed Anvifen 250 mg 3 times a day; in addition, patients could take the drug during the day if necessary, as well as during night or early morning awakening (without exceeding the maximum daily dose of 1500 mg). The duration of drug administration and observation of patients was 30 days. RESULTS: The severity of CS (before and after treatment): subclinical - in 14 and 20, mild - in 15 and 37, moderate - in 17 and 10, severe - in 14 and 0, critical - in 7 and 0 patients, respectively. The average CSI score was 40.5[30; 50] and 32.5[25; 37.3] (p=0.00001). The severity of meteosensitivity according to VAS before and after treatment was 70 [60; 80] and 25 [20; 30] points (p=0.00002). The average ASHS score for subjective sleep characteristics before and after treatment was 13 [12; 15] and 26 [25; 28] points (p=0.00001). CONCLUSION: Central nervous system, insomnia and meteosensitivity are common clinical conditions in patients with coronary artery disease. Inattention to them leads to insufficient effectiveness of specific therapy and worsening of the course of cardiovascular diseases. The GABAergic drug Anvifen effectively reduces CS, meteosensitivity and improves sleep. The CSI is a simple and informative tool for assessing cerebral dysfunction in patients with coronary artery disease and can be recommended for daily routine practice in order to optimize personalized medical care.

[Effectiveness of Anvifen in the treatment of insomnia in elderly patients]. / Effektivnost' preparata Anvifen pri lechenii insomnii u pozhilykh patsientov.

OBJECTIVE: Purpose of the study to determine the effectiveness of Anvifen in the case of insomnia and meteosensitivity as comorbid stress-induced disorders. MATERIAL AND METHODS: 67 patients aged 60-70 years were examined, who were randomly divided into two groups: group 1 - 33 patients (20 men, 13 women), group 2 - 34 patients (19 men, 15 women). The average age of group 1 was 62.7 [61; 65] years, group 2 was 63.1 [60; 66] years (p=0.28). Research methods: questionnaire for scoring subjective characteristics of sleep, assessing the influence of meteosensitivity on daily activity using a numerical rank scale (NRS) for the previous three months. Patients in group 1 took Anvifen 250 mg (capsules) in the morning and afternoon, 500 mg (2 capsules) in the evening at 10 p.m., and upon awakening at night - an additional 250 mg of the drug per capsule. Patients in group 2 took Anvifen powder (extracting it from the capsule) 250 mg in the morning and afternoon, 500 mg in the evening at 10 p.m., and upon awakening at night - an additional 250 mg of the drug. The time from the nightly intake of Anvifen to the onset of sleep was also assessed on a three-degree scale: «fast¼, «long¼, «very long¼. The duration of treatment was 4 weeks. RESULTS: Baseline results of measured parameters did not differ significantly between groups. After completion of treatment, the total score of subjective sleep characteristics improved in 1st (p=0.00001) and 2nd (p=0.000001) groups. Significant differences from group 1 for the better in group 2 were in «quality of sleep¼ (p=0.00027) and «quality of awakening¼ (p=0.00001). Weather sensitivity decreased in 1st (p=0.00001) and 2nd (p=0.000001) groups. CONCLUSION: Anvifen showed good effectiveness in the treatment of two comorbid conditions of elderly people - insomnia and meteosensitivity. Using the drug in powder form allows you to get a faster and better effect without side-effects.
