[Efficacy of the energy-modifier cytoflavin in the treatment of patients with hypertensive encephalopathy].

AIM: To evaluate the efficacy of cytoflavin in the treatment of patients with hypertensive encephalopathy (HE). SUBJECTS AND METHODS: One hundred and forty patients aged 39 to 73 years, diagnosed with HE, were examined and randomized to 2 groups. A study group (n = 74) received cytoflavin in a dose of 2 tablets b.i.d. on days 1 to 25 days inclusive during standard basic therapy. A comparison group (n = 66 persons) had standard basic therapy only. A control group consisted of 30 apparently healthy individuals. The investigators studied the frequency of headache, dizziness, and other complaints and the intensity of cephalalgic syndrome, by using a visual analog scale, the quality of life by the Medical Outcomes Study 36-Item Short-Form Health Survey (MOS SF-36) questionnaire, that of sleep by the subjective sleep characteristics questionnaire elaborated at the Moscow City Somnological Center, the level of asthenia by a subjective asthenia rating scale (Multidimensional Fatigue Inventory (MFI-20), and autonomic status, by applying objective and subjective scales on days 1 and 25 of therapy. RESULTS: The study has shown that cytoflavin used in the above dose for 25 days reduces the frequency and magnitude of complaints of headache, dizziness, "venous" complaints, the degree of autonomic and asthenic disorders, and impairments in the quality of sleep and life in the patients with HE at all disease stages. A stepwise discriminant analysis has indicated that the degree of cephalgic syndrome, and autonomic disorders, and worse sleep quality are the most effective points for using the energy-modifier cytoflavin. CONCLUSION: HE treatment based on the current pathogenetic principles may have a preventive impact on the development of HE or slow down the rate of its progression.

[Central hemodynamics and cerebrovascular disorders in patients with idiopathic arterial hypotension].

A total of 65 patients (mean age 40.2 +/- 8.1 yr) with neurologic and neuropsychological disorders associated with long-term idiopathic arterial hypotension (IAH) were studied to estimate the state of their central blood circulation. Neuropsychological conditions were estimated from the state of higher psychic functions, such as memory speech, gnosis, praxis, cognition, attention, counting, writing, and reading abilities. Central hemodynamics was studied by 24 hr monitoring arterial pressure and echocardiography. Group 1 included patients without neurologic problems (n = 19), group 2 consisted of patients with early manifestations of chronic cerebrovascular insufficiency (n = 46, 71%). They were older than patients of group 1 and had a long history of IAH. It was shown that most patients presented with stably reduced systolic and diastolic AP and non-dipper type of low 24-hour SAD index. The cardiac index was elevated due to increased left ventricular ejection fraction (group 1) or increased heart rate (group 2). The severity of neuropsychic disorder was negatively related to SAD and DAD indices and positively to systolic hypotension time.
