The Relationship

ObjectiveThe severity of cerebral small vessel disease (SVD) is assessed through neuroimaging findings, including hypertensive arteriopathy (HA)-SVD and cerebral amyloid angiopathy (CAA)-SVD. HA-SVD and CAA-SVD have been collectively estimated as total scores: the HA-SVD and CAA-SVD scores, respectively. Previous reports suggest that HA-SVD scores are associated with cognitive function; however, the relationship between CAA-SVD scores and cognitive function remains unclear. Therefore, we examined the association between CAA-SVD scores and cognitive function. Furthermore, we developed a modified CAA-SVD score considering cortical microinfarcts and posterior dominant white matter hyperintensities, which are imaging findings of CAA, and examined the association between these scores and cognitive function in the same patient group.DesignProspective study.SettingSingle centre study from a memory clinic.ParticipantsSubjects were diagnosed with mild cognitive impairment (MCI) or mild dementia in our memory clinic between February 2017 and July 2019 and underwent clinical dementia rating scale and brain MRI assessment. A total of 42 patients (aged 75.3±9.12 years) were registered prospectively.Primary and secondary outcome measuresWe evaluated intellectual function, memory, frontal lobe function and constructional ability. Furthermore, the relationship between each score and cognitive function was examined.ResultsThe CAA-SVD score showed significant associations with cognitive function (R2=0.63, p=0.016), but the HA-SVD score did not (R2=0.41, p=0.35). The modified CAA-SVD score was also significantly associated with cognitive function (R2=0.65, p=0.008).ConclusionCognitive function is associated with the CAA-SVD score, and more efficiently with the modified CAA-SVD score, in memory clinic patients. Although we have not validated the weighting of the modified CAA-SVD score, these scores can be a predictor of cognitive deterioration in patients with MCI and mild dementia.

Objective: Evaluation of the UK NEQAS 2008 guidelines for the interpretation of spectrophotometric xanthochromia. Method: A search of the laboratory database for all the xanthochromia test results between May 1st 2008 and May 1st 2009 was performed. Medical charts were reviewed for patients of Hôpital de l’Enfant-Jésus (HEJ) that had at least one detectable pigment (bilirubin, oxyhemoglobin, or methemoglobin). Xanthochromia results obtained with 4 different criteria (Chalmers original, Modified Chalmers, Duiser and UK NEQAS 2008) were compared. Results: We reviewed 41 medical charts (2 patients with duplicate lumbar punctures (LP) for a total of 43 LP). For these 41 patients there were 11 positive xanthochromia results, 5 of which were in concordance with a final diagnosis of subarachnoid hemorrhage (SAH). The diagnosis of the 6 other positive xanthochromia results were as follow: meningeal spread of a lymphoma, cerebral amyloid angiopathy, exertional headache, viral encephalitis with a possibility of petechiaes on the cerebral CT and second LP. Interpretation (negative/positive) of 40/43 LP was identical for the 4 methods. 2 LP were positive with Duiser and UK NEQAS 2008 but negative with Chalmers approaches (final diagnosis: SAH and cerebral amyloid angiopathy). 1 LP was positive only by the Duiser method (viral encephalitis). Conclusions: UK NEQAS 2008 guidelines identified all SAH but are sensitive to traumatic and pathologic meningeal lesions. Except for a case of viral encephalitis with a suspicion of cerebral petechiaes on CT, UK NEQAS 2008 gave xanthochromia results similar to the one in use at HEJ (Duiser). Chalmers original and Modified Chalmers methods missed one of the five SAH.

The present article addresses the definition of cerebral amyloid angiopathy (CAA) and its symptoms based on the analysis of the medical case; the issues of diagnosis and treatment of this pathology are discussed. The Boston criteria, which became the basis for diagnosis, study of clinical manifestations and progression of CAA and approaches to its therapy, are presented. Methods and modes of neuroimaging, including magnetic resonance imaging (MRI), which verify micro cerebral haemorrhage, are described. At the same time, the role and significance of cardiac arrhythmias in the genesis of ischemic stroke are discussed, and scales for assessing the risk of its occurrence are presented. The observation of the neurological, somatic, neuroimaging, neuropsychological status of a 62-year-old patient confirms quite rare combination of probable CAA, paroxysmal atrial fibrillation and repeated hemorrhagic functional apoplexy (FA). The relevance of the case described, is a complex clinical dilemma based on mutually exclusive recommendations for the pharmacological correction of such conditions. It is emphasized that in many multicenter clinical studies on the effectiveness of antithrombotic medication (antiaggregants, anticoagulants) in the treatment and prevention of ischaemic functional apoplexy , an important exclusion criterion is a hemorrhagic stroke in past history (including the multiple changes in haemostasis indicators). Taking into account the obtained clinical and laboratory data in the dynamics, the tactics of treating the described patient were determined. The results of studies related to the treatment of comorbid pathology that should become the subject of the development of a personalized algorithm for managing patients in each specific case, are discussed.
