More than 50,000 haematopoietic stem cell transplantations (HSCTs) are performed worldwide each year to treat malignant blood cancers, solid tumours, bone marrow aplasia, primary immunodeficiency conditions, autoimmune disorders, and storage disorders. The success of HSCTs depends on many factors, including patient's past medical history. \u0000Purpose. To assess the effect of an acute cerebrovascular accident (CVA) that occurred before the HSCT on the transplantation outcome in patients with blood cancer. \u0000Materials and methods. We examined the results of 899 transplantations conducted between 2016 and 2018 at the R.M. Gorbacheva Research Institute for Pediatric Oncology, Haematology and Transplantation of the Pavlov First Saint Petersburg State Medical University. We analysed transplantation parameters, as well as donor and recipient characteristics. Apart from intergroup comparisons, pseudo-randomization was performed using the Propensity Score Matching method. The survival rate analysis was conducted using the KaplanMeier estimate and the log rank test. \u0000Results. Sixteen patients (1.8%) had cerebrovascular events in their past history before the HSCT: ischaemic stroke in 0.4% of cases and haemorrhagic stroke or intracerebral haemorrhage in 1.4% of cases. Patients with a history of cerebrovascular events included more people with leukaemia (p = 0.02), had more often received an allogenic transplant (р = 0.01), the donors more often had a partial rather than a full HLA match with the recipient (р = 0.06), had a lower body mass index (р = 0.02), and a lower Karnofsky/Lansky score (р = 0.01) than patients in the control group. The presence of a cardiovascular event had a statistically significant association with reduced overall survival rate of HSCT recipients (р = 0.0012). \u0000Conclusion. Patients with blood cancer and stroke preceding the transplantation do not typically have any 'classical' risk factors (diabetes mellitus, venous system disorders, decreased cardiac output, significant atherosclerotic changes in precerebral arteries), therefore, secondary prevention guidelines for CVA during treatment of the main disease may not be effective and cannot be relied on. This article discusses the most likely causes of CVA in patients with blood cancer. A history of CVA before HSCT may have a significant effect on the transplantation outcome, but is not a contraindication for this treatment method. Recipient selection is a very important stage in HSCT planning. A multidisciplinary team should find a balance between the indications and contraindications for performing HSCT from an unrelated donor.","PeriodicalId":36946,"journal":{"name":"Annals of Clinical and Experimental Neurology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88687001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cerebral small vessel disease (CSVD), associated with age and vascular risk factors, as well as the main cause of vascular and degenerative mixed cognitive impairment (CI). Previously established microstructural predictors of CI (axial diffusion in normal-appearing periventricular white matter of the posterior left frontal lobe, the right midcingulate cortex, and the middle posterior part of the corpus callosum) can be used to calculate an integrative factor, exceeding the threshold value for which indicates the presence of CI. The use of this factor in the diagnosis of CI in CSVD is supported by the fact that leading mechanisms of CSVD are involved in the damage to areas of the brain that are strategic for CI. \u0000The aim of this study was to clarify the link between the known microstructural predictors of CI in CSVD and MRI findings that correspond to the main mechanisms of CSVD. \u0000Materials and methods. Patients (n = 74; including 48 women; average age 60.6 6.9 years) with CSVD and CI of varying severity underwent phase-contrast MRI and voxel-based morphometry (3T) to assess arterial, venous and CSF flow, as well as atrophy. \u0000Results. The established microstructural predictors of CI correlated with measures of arterial and venous blood flow, as well as atrophy. Linear regression models allow us to estimate cognitive impairment (CI) predictors in cerebral small vessel disease (CSVD), based on increased arterial velocity pulse index, CSF flow at the level of the cerebral aqueduct, cerebral aqueduct area and lateral ventricles volume, when there is reduced blood flow in the superior sagittal sinus and the overall arterial blood flow. \u0000Conclusion.

Timely identification of cognitive impairment is very important, with standardized screening instruments required to assess the cognitive status. However, the arsenal of such screening scales available to clinicians in Russia is limited and requires expansion. According to numerous international studies, the Addenbrookes Cognitive Examination III (ACE-III) has the necessary sensitivity and specificity, which speaks well for developing and validating a Russian language version. \u0000The aim of the study was the linguistic and cultural adaptation of the Addenbrookes Cognitive Examination III (ACE-III). \u0000Materials and methods. A forward and back translation was performed of three versions of the scale and the scoring guidelines. A preliminary version of the ACE-III was developed, pilot testing of the preliminary version was conducted, and a final Russian language version was then developed with the help of a philologist/linguist, and experts in neuropsychology and neurology, who work specifically with patients with cognitive impairments. Pilot testing of the preliminary version of the ACE-III involved 16 neurological patients at the Research Center of Neurology and the Pirogov National Medical and Surgical Centre, who were aged 3774 (60.25 10.8) years and 56% of whom were women. The patients clinical condition corresponded to the diagnostic criteria for cerebrovascular disease (n = 12), Parkinson's disease (n = 3) and spinocerebellar ataxia (n = 1). \u0000Results. Neither the subjects nor the examiners had any difficulty in understanding the instructions or the content during testing. Further work was done based on the results of the pilot testing, and three final versions of the scale (A, B and C) were accepted, as well as the scoring guidelines, a link to which is provided in the article. \u0000Conclusion.

T cells play a significant role in neuroinflammation in Parkinson's disease (PD). Gamma delta T cells are an under-researched 'minor' subpopulation of T cells. An assessment of the immune system in patients with PD, with a focus on Т cells, provides new data on the pathogenesis of neurodegenerative diseases. \u0000The aim of the study was to examine the lymphocyte subpopulations, nonclassical Т cells, as well as cytokine production in patients with 3 stage PD complicated by motor fluctuations. \u0000Materials and methods. We examined 20 patients with 3 stage PD receiving dopaminergic combination therapy (main group) and 20 age-matched patients with chronic cerebrovascular disease (comparison group). Considering the suspected role of chronic constipation in maintaining dysbiosis and chronic inflammation in patients with PD, the presence of constipation was an inclusion criterion for this study. The subpopulation profile of the peripheral blood lymphocytes was assessed using flow cytofluorometry, as well as cytokine levels using enzyme linked immunosorbent assay. \u0000Results. It was found that the number of mature CD3+ T cells with or chains as the T-cell receptors (TCR) in the lymphocyte population was significantly lower in patients with PD median 74% (57.383.5)) than in the comparison group (median 80% (73.086.0); р = 0.014.

At the same time, the number of CD3CD56+ NK cells was significantly higher in the group of patients with PD (16.4% (934)) vs. the comparison group 8.7% (515); р = 0.001. Moreover, the main group had a statistically significantly higher number of activated CD3CD8+ NK cells 7% (4.513.5) vs. the comparison group 3.5% (0.864.9); р 0.001.
