cerebral amyloid angiopathy related inflammation

If there is no response to corticosteroid therapy within 3 weeks, biopsy should be reconsidered to confirm the diagnosis. 5. Amyloidogenic peptides in this condition are nearly always the same ones found in alzheimer disease. DiFrancesco JC, Touat M, Caulo M, Gallucci M, Garcin B, Levy R, et al. Fukasawa R, Shimizu S, Hirose D, Kanetaka H, Umahara T, Obikane H, et al. [48,49], Gadolinium enhancement of parenchyma or leptomeninges may or may not be present [Figure 1],[43,50] although the proportion of enhancing cases in CAA-RI is significantly higher than that in non-inflammatory CAA cases. Medicine (Baltimore). [18] Although the APOE 2 allele is considered a protective factor against AD, it clearly increases the risk of vascular disease. . Yamada M.

Pearls & Oy-sters: CAA-related inflammation presents as subacute cognitive decline in a patient with Parkinson disease. [28] This strongly suggests that an immune response to A is responsible for CAA-RI. Cerebral Amyloid Angiopathy (CAA) Associated with Inflammation (Inflammatory CAA) Background: Cerebral amyloid angiopathy (CAA) is characterized by deposition of amyloid-beta in the media and adventitia of cortical and leptomeningeal arteries. Acta Neuropathol 1974; 27:131137. Objective. Reid AH, Maloney AF. [20] Currently, most evidence favors the hypothesis that inflammation is triggered by an autoimmune response to the deposited A protein. It is not clear why only a small proportion of patients with CAA develop inflammation against A. The diagnostic criteria for both probable and possible inflammatory cerebral amyloid angiopathy require at least one corticosubcortical hemorrhagic lesion 4, which is best demonstrated as signal loss on T2*-weighted sequences (susceptibility-weightedor gradient echo): cerebral macrobleed (intraparenchymal hematoma), cerebral microbleed (cerebral microhemorrhage). The results of lumbar puncture revealed that more than 80% of patients had increased CSF protein, 44% had pleocytosis,[17] and generally no oligoclonal bands were detected. Martucci M, Sarria S, Toledo M, Coscojuela P, Vert C, Siurana S, et al.

WMH and vasogenic edema accompanied by a mass effect make brain tumors a highly suspected differentiation. However, some studies have questioned the idea. The diagnostic criteria for "probable" inflammatory cerebral amyloid angiopathy require white matter hyperintensities on T2-FLAIRthat are asymmetric and extend to the immediately subcortical white matter 4. -, Salvarani C, Hunder GG, Morris JM, Brown RD, Christianson T, Giannini C. A-related angiitis: comparison with CAA without inflammation and primary CNS vasculitis. It also remains unclear what should be done for those diagnosed with possible CAA-RI, and whether they still need to undergo brain biopsy. 32. Other differential diagnoses include viral or autoimmune encephalitis, cerebral venous thrombosis, acute disseminated encephalomyelitis (ADEM), Hashimoto encephalopathy, neurosarcoidosis, and acute toxic-metabolic leukoencephalopathy. (2016) Journal of Alzheimer's disease : JAD. 1-6 It differs from more common noninflammatory forms of CAA .

This disorder typically responds to steroids but addition of other immune suppressants may be needed in some cases to control the disease. Besides, the study did not propose a specific treatment or plan for further examination for patients meeting a diagnosis of possible CAA-RI. Liang JW, Zhang W, Sarlin J, Boniece I. 9. There are still many questions related to CAA-RI that require investigation. Inflammatory cerebral amyloid angiopathy: the overlap of perivascular (PAN-like) with vasculitic (A-related angiitis) form: an autopsy case. Cheng AL, Batool S, McCreary CR, Lauzon ML, Frayne R, Goyal M, et al. Epub 2019 May 25. However, biopsy is invasive; consequently, some criteria for the diagnosis of CAA-RI have been based on clinical and radiological data. -, Yeh SJ, Tang SC, Tsai LK, Jeng JS. Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. Cerebral amyloid angiopathy is often asymptomatic, which can cause dementia, intracranial hemorrhage, or transient neurological events. Many cases have reported that patients were misdiagnosed with tumors, and the diagnosis was modified to CAA-RI when the data were retrospectively analyzed or after the biopsy results became available. 35. MRA and vessel wall imaging may show medium-sized arteries involved with multifocal stenoses with wall thickening/enhancement 11.

[64] Another patient was first diagnosed with PRES, which was responsive to anti-edema intravenous steroid and antihypertensive therapy. [11] This phenomenon may be explained by the fact that the blood vessel wall in cases of ICAA is less destroyed than that in cases of ABRA. After treatment with corticoids, (D) WMH faded significantly. Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Center Experience and a Literature Review. Clinical Presentation: Patients typically present with seizures, headache, and strokelike episodes, along with an acute or subacute decline in cognitive status. Some authors are consistent with the terms we have used here, while some call the two subtypes CAA-RI and ABRA. 38. Course of cerebral amyloid angiopathy-related inflammation. Medicine (Baltimore). Inflammatory Disorders of the Central Nervous System Vessels: Narrative Review. Cerebral amyloid angiopathy-related inflammation (CAAri) is characterized by vasogenic edema and multiple cortical/subcortical microbleeds, sharing several aspects with the recently defined amyloidrelated imaging abnormalities (ARIA) reported in Alzheimer's disease (AD) passive immunization therapies.

These cases emphasize that CAA-RI is a diagnosis by exclusion. Cerebral amyloid angiopathy-related inflammation: imaging findings and clinical outcome. 8600 Rockville Pike Brain MRI, particularly FLAIR and T2/SWI sequences, is the most important imaging modality for the identification of patients suspected of CAA-RI. [13] For patients diagnosed with probable CAA-RI by means of these criteria, immunosuppressive therapy can be given empirically to avoid brain biopsy. Moussaddy A, Levy A, Strbian D, Sundararajan S, Berthelet F, Lanthier S. Inflammatory cerebral amyloid angiopathy, amyloid-beta-related angiitis, and primary angiitis of the central nervous system: similarities and differences. Findings supporting CAA-RI include patchy or confluent T2 hyperintensity of subcortical white matter lesions, which are mostly asymmetric, in addition to the presence of multiple, strictly lobar CMBs and cSS on T2 or SWI, which is also a typical finding in CAA [Figure 1]. The incidence of multiple lobar CMBs, as well as the total number of CMBs is significantly higher in CAA-RI patients.

In one case, heart transplantation was performed because of sarcoid cardiomyopathy, followed by long-term use of immunosuppressants, and CAA-RI occurred during hospitalization after mycobacterial infection. Our clinical experience also supports this conclusion [Figure 1]. Beta-amyloid peptides bind to lipoproteins and apolipoproteins E and J in the CSF and to HDL particles in plasma, inhibiting metal-catalyzed oxidation of lipoproteins.

[22] Moreover, ischemic stroke is more common in PACNS than in CAA-RI,[24] and there have been only a few cases of patients with CAA-RI presenting with ischemic stroke. Introduction 12. However, anticoagulation was later suspended due to cerebral hemorrhage, and the patient was finally diagnosed with CAA-RI. [2,46,68] The most common abnormality found in PACNS is the presence of proximal or distal stenosis on MRA or conventional digital subtraction angiography; this is not commonly seen in CAA-RI.
