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.

Cerebral Amyloid

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.

We report the case of long-term follow-up of brain magnetic imaging of cerebral amyloid angiopathy. Cerebral amyloid angiopathy is often considered a major cause of spontaneous intracerebral hemorrhage in the elderly. This case illustrates the markedly progressive clinical and radiological features of the vasculopathic process in 10 years.

Background and aimsHaving anecdotally noted a high frequency of lobar-restricted cerebral microbleeds (CMBs) mimicking cerebral amyloid angiopathy (CAA) in patients with previous cardiac surgery (especially valve replacement) presenting to our transient ischaemic attack (TIA) clinic, we set out to objectively determine the frequency and distribution of microbleeds in this population.MethodsWe performed a retrospective comparative cohort study in consecutive patients presenting to two TIA clinics with either: (1) previous coronary artery bypass grafting (CABG) (n=41); (2) previous valve replacement (n=41) or (3) probable CAA (n=41), as per the Modified Boston Criteria, without prior cardiac surgery. Microbleed number and distribution was determined and compared.ResultsAt least one lobar-restricted microbleed was found in the majority of cardiac surgery patients (65%) and 32/82 (39%) met diagnostic criteria for CAA. Valve replacement patients had a higher microbleed prevalence (90 vs 51%, p<0.01) and lobar-restricted microbleed count (2.6±2.7 vs 1.0±1.4, p<0.01) than post-CABG patients; lobar-restricted microbleed count in both groups was substantially less than in CAA patients (15.5±20.4, p<0.01). In postcardiac surgery patients, subcortical white matter (SWM) microbleeds were proportionally more frequent compared with CAA patients. Receiver operator curve analysis of a ‘location-based’ ratio (calculated as SWM/SWM+strictly-cortical CMBs), revealed an optimal ratio of 0.45 in distinguishing cardiac surgery-associated microbleeds from CAA (sensitivity 0.56, specificity 0.93, area under the curve 0.71).ConclusionLobar-restricted microbleeds are common in patients with past cardiac surgery, however a higher proportion of these CMBs involve the SWM than in patients with CAA.

The Impact

Cerebral amyloid angiopathy (CAA) is a condition characterised by accumulation of amyloid beta protein (Aβ) in the wall of cerebral blood vessels which increases the risk of intracranial haemorrhage and contributes to cognitive impairment. We describe the case of a man around the age of 70 with ‘probable’ CAA according to the modified Boston criteria and severe depression whose depression was treated successfully with electroconvulsive therapy (ECT). To the best of our knowledge, there are no earlier published reports of ECT in a patient with CAA. We briefly discuss possible safety measures for these patients, the impact of ECT on cognition in CAA and a possible influence of ECT on Aβ clearance.
