(ALUNA, 2021-10) Kopchak Oksana; Odintsova Tetiana; Pulyk Oleksandr
The aim: To clarify the influence of different risk factors on cognitive impairment (CI) in general and in separate domains and their association with MRI findings in patients with relapsing-remitting (RRMS) and progressive forms of multiple sclerosis (SPMS and PPMS). Materials and methods: One hundred and thirty-seven participants with MS (102 females and 35 males) aged from 22 to 69 years were enrolled into this study. All patients completed the Montreal Cognitive Assessment (MoCA), Beck Depression Inventory (BDI), Hamilton Anxiety Rating Scale (HAM-A) and undergone MRI. Results: According to MS phenotypes all participants were divided into two groups: patients with RRMS (n= 106) and with progressive phenotypes (n= 31). A significant positive correlation was present between MoCA and BDI scores in all participants (p= 0,0015). Presence of anxiety did not demonstrate any valid influence on cognitive performance, although severe anxiety was significantly more often found in subjects with progressive phenotypes in presence of brain atrophy (p= 0,0028). Patients with higher education had no CI more frequently compare to those without it (p= 0,0019), whereas, participants smoking cigarettes had higher prevalence of severe CI than non-smokers (p= 0,0061). Conclusions: Among cognitive domains memory, visual-spatial and executive functions, abstract thinking were impaired the most in MS patients, though abstract thinking was more often affected in progressive forms. The results demonstrated that physical disability, depression and smoking negatively impacted cognitive performance, meanwhile presence of higher education demonstrated a favorable influence on cognition in MS patients.
PECULIARITIES OF THE GUT MICROBIOTA IN PATIENTS WITH MIGRAINE COMPARING TO HEALTHY INDIVIDUALS
(Aluna Publishing, 2022-09) Kopchak Oksana; Hrytsenko Olena; Pulyk Oleksandr
The aim: Analyze the gut microbiome state in patients with migraine (M) and healthy individuals, to assess possible correlations between the detected changes in patients with migraine and the frequency, intensity of headaches, psycho-emotional state of the patients, and their quality of life. Materials and methods: 100 objects were enrolled, divided into 2 groups: main – patients with M and control – healthy volunteers. Investigation of the intestinal microbiome was performed by chromato-mass spectrometry. For M patients the following scales were used: Visual Analogue Scale (VAS), Migraine Disability Assessment (MIDAS), Back Depression Inventory (BDI). Results: In main group increased amount of Alcaligenes spp (p = 0.0061), Clostridium coccoides (p = 0.0021), Clostridium propionicum (p = 0.0287), Eggerthella lenta (p = 0.0138), Pseudonocardiaspp (p = 0.0210),Rhodococcus spp (p = 0.0164), Candidaspp (p = 0.0079), Micromycetes spp(campesterol) (p = 0.0011) were found. Patients with M had a raised amount of Herpes simplex (p = 0.0305) and endotoxin level (p = 0.0459). Differences in gut microorganisms in both groups were significant. In patients with M negative correlations were observed between Alcaligenes spp ammount and BDI score (r = -0.6226, p =0.007), VAS score (r = -0.489, p = 0.046), headache frequency (r = -0.487, p = 0.046); between the levels of Clostridium coccoides and MIDAS score (r =-0.51, p = 0.035), BDI score (r = -0.54, p = 0.025) and positive correlation between Eggerthellalenta level and VAS score (r =0.4830, p=0.049). Conclusions: Correlations between changes of gut microbiome and M are promising for further research.
VASCULAR RISK FACTORS AND COGNITIVE FUNCTIONS IN THE PATIENTS WITH CEREBROVASCULAR DISEASE
(Aluna, 2020) Kopchak Oksana; Bachinskaya Natalia; Pulyk Oleksandr
The aim: To assess the severity of cognitive impairment (CI) in patients with cerebrovascular disease (CVD) depending on the number of vascular risk factors (VRF). Materials and methods: The study consisted of five hundred and eighty patients with CVD (247 females and 333 males) aged from 45 to 89 years (mean age: 64,1±8,9 years). The patients were divided into 6 groups (I, II, III, IV, V, VI) depending on the number of VRF. The examination consisted of a standard clinical evaluation, neurological examination, the application of neuropsychological tests (the MMSE; the PALT/The Paired Associates Learning Test; clock drawing test), laboratory tests, MRI of brain. Results: According to ANOVA, the greater the number of VRF the patients had, the lower was their total MMSE score corresponding to more pronounced cognitive decline (F=2,97, p=0,012). A significant negative correlation between patients’ age and their MMSE score was detected regardless of their VRF count. The patients of the V and VI groups had substantially lower parameters of immediate, delayed memory and clock drawing test score comparing to the patients of the I group. Conclusions: The presence of 4 and more VRF was related to more pronounced CI in the patients with CVD. Decline of different aspects of memory, attention, spatial orientation, abstract thinking, planning, concentration, executive and visuospatial skills in groups of patients with 4,5 and 6 vascular risk factors was established. Age was substantially associated with cognitive decline in all the group of patients
