Piazza F, Greenberg SM, Savoiardo M, Gardinetti M, Chiapparini L, Raicher I, et al. 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. In general, the same patient group affected by cerebral amyloid angiopathy is affected, and thus most patients are elderly, typically 60-80 years of age. [18] The clinical and radiological manifestations may be initially relieved after glucocorticoid therapy, but can relapse after withdrawal of steroids or during dose decrease. Inflammatory Cerebral Amyloid Angiopathy, Amyloid-Related Angiitis, and Primary Angiitis of the Central Nervous System. (A) Confluent WMH. The patient met the criteria for probable cerebral amyloid angiopathy-related inflammation (CAA-ri) and responded favorably to high-dose methylprednisolone. 2022 Oct 13;58(10):1446. doi: 10.3390/medicina58101446. It is easy for doctors to diagnose CAA-RI when patients were APOE 4/4 homozygotes with typical clinical characteristics and image. [57] A reduction of CMBs was found in one case after immunotherapy, but it cannot be ruled out that the natural course of CAA-RI may include a spontaneous reduction in CMBs. Once the diagnosis is made, glucocorticoids or even immunosuppressants should be adopted in order to improve the prognosis. Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. Typical images of cerebral amyloid angiopathy-related inflammation. Epub 2022 Mar 14. Early diagnosis and timely treatment may improve prognosis. However, many authors interchange the terms "cerebral amyloid angiopathy-related inflammation" and "inflammatory cerebral amyloid angiopathy," either encompassing of amyloid -related angiitis 8 or in distinction to it 3. The use of glucocorticoids and immunosuppressants improves prognosis. Masrori P, Montagna M, De Smet E, Loos C. Posterior reversible encephalopathy syndrome caused by cerebral amyloid angiopathy-related inflammation. ABRA; CAA; CAA-related inflammation; CAAri; CNS inflammation; CNS vasculitis a beta-related angiitis; Cerebral amyloid angiopathy. 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. Historically, only ICAA was initially considered to be the only inflammatory form of CAA,[9] while ABRA was thought to represent coexisting primary angiitis of the central nervous system (PACNS) and CAA. Moosavi B, Torres C, Jansen G. Case 232: Amyloid -related Angiitis. After several recurrences, WMH and CMBs progressed and long-term follow-up led to a diagnosis of CAA-RI. Cerebral amyloid angiopathy-related inflammation: imaging findings and clinical outcome. (2016) Neurology. Salvarani C, Morris JM, Giannini C, Brown RD Jr, Christianson T, Hunder GG. Xu YY, Chen S, Zhao JH, Chen XL, Zhang JW. [55] An APOE 4/4 homozygous patient with a rare SORL1 mutation has been reported. PMC However, there are many atypical cases or cases without T2/SWI sequence that were initially misdiagnosed, in whom the diagnosis was later revised. [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. [65] Therefore, these two diseases are sometimes difficult to distinguish, and it may be necessary to observe changes during follow-up to obtain the correct diagnosis. [70] The clinical features of relapse are widely distributed, among which the decline of cognitive function and encephalopathy are the most common symptoms. 33. CAA is an important cause of lobar intracerebral hemorrhage in older adults [ 1,2 ]. Cases of an isolated leptomeningeal process on imaging are more commonly categorized as amyloid related angiitis, within the limitations of variable terminology noted above 6. 24. Cerebral amyloid angiopathy (CAA) is presented with progressive deposition of amyloid proteins within the cortical and leptomeningeal arteries, which is a common pathology in the elder [1, 2].In recent years, studies show that coexisting inflammations found in CAA patients, such as vasculitis or perivasculitis, have been recognized as CAA-related inflammation (CAA-ri) []. Please enable it to take advantage of the complete set of features! Auriel et al[13] updated the criteria in 2016, defined the WMH pattern specific for distinguishing between probable and possible CAA-RI, and proposed cSS as a marker of hemorrhage. Unauthorized use of these marks is strictly prohibited. Cerebral amyloid angiopathy and cerebral amyloid angiopathy-related inflammation: comparison of hemorrhagic and DWI MRI features. [17,18] The main patient group is the elderly, with an average age of 67 at diagnosis; yet, this is still younger than that of CAA patients. Some authors are consistent with the terms we have used here, while some call the two subtypes CAA-RI and ABRA. [17] And the youngest case with pathologic evidence ever reported was 42 years old.[34]. 46. Finally, a multi-center prospective cohort study, using unified standards for the collection of data, application of designed therapies, and follow-up strategy is necessary. This site needs JavaScript to work properly. Disclaimer. These patients typically present with subacute mental status changes, headaches, and seizures, typically at a slightly younger age than those presenting with . 41. Epub 2014 Feb 11.

Cerebrospinal fluid, MRI, and florbetaben-PET in cerebral amyloid angiopathy-related inflammation. The distribution of CMBs does not follow the regional pattern of occipital dominance in non-inflammatory CAA. Renard D, Wacongne A, Ayrignac X, Charif M, Fourcade G, Azakri S, et al. This article reviews the pathology and pathogenesis, clinical and imaging manifestations, diagnostic criteria, treatment, and prognosis of CAA-RI, and highlights unsolved problems in the existing research. [20] Currently, most evidence favors the hypothesis that inflammation is triggered by an autoimmune response to the deposited A protein. 34 (10): 1958. Leptomeningeal contrast enhancement is seen in approximately half of patients 1,2. First, ABRA has the same radiological characteristics as ICAA, which are not common in PACNS. Cerebral amyloid angiopathy-related inflammation (CAA-ri), also referred to as inflammatory cerebral amyloid angiopathy and A-related angiitis, is a distinct subset of cerebral amyloid angiopathy (CAA) characterized by an autoimmune reaction to cerebrovascular -amyloid deposits. Giant cell arteritis and arteriolitis associated with amyloid angiopathy in an elderly mongol. Subcortical white matter will demonstrate usually a solitary area of low density with localized mass effect 1,2. [9,10] Two pathological subtypes are now generally accepted: non-destructive perivascular inflammation (inflammatory CAA [ICAA]) and transmural or intramural inflammation (A-related angiitis [ABRA]). Medicina (Kaunas). In fact, in a subgroup of patients, spontaneous remission is encountered 1. Table 3. An increase in inflammatory biomarkers has been observed in CAA-RI patients in different studies. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Phrases such as CAA associated with inflammation, CAA-RI, ICAA, and ABRA are used interchangeably. Key Diagnostic Features: Objective. 26. 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. In addition, there is a need to determine more biomarkers by which to modify the diagnostic criteria and further improve diagnostic efficiency. 15. The most recent systematic review included 213 pathologically confirmed cases of CAA-RI. Theodorou A, Palaiodimou L, Safouris A, Kargiotis O, Psychogios K, Kotsali-Peteinelli V, Foska A, Zouvelou V, Tzavellas E, Tzanetakos D, Zompola C, Tzartos JS, Voumvourakis K, Paraskevas GP, Tsivgoulis G.

Zhu X, Schrader JM, Irizarry BA, Smith SO, Van Nostrand WE. [16,17] However, the terms used to describe this disease are confusing. Cerebral amyloid angiopathy (CAA) is a condition in which proteins called amyloid build up on the walls of the arteries in the brain. A nationwide survey demonstrated that its prevalence is about 0.13 per 100,000 population in Japan. [28] Antibody levels decrease after corticosteroid therapy,[2,42] indicating that anti-A autoantibody may be used as a biomarker for both diagnosis and monitoring the effect of treatment. to maintaining your privacy and will not share your personal information without Department of Neurology, Peking Union Medical College Hospital, Peking Union Medical College and Chinese Academy of Medical Sciences, Beijing 100730, China. 2016YFC1300500-505). may email you for journal alerts and information, but is committed Your message has been successfully sent to your colleague. For these reasons, this article does not attempt to distinguish between subtypes and treats the terms interchangably. An official website of the United States government. The resultant vascular fragility tends to manifest in normotensive elderly patients as lobar intracerebral haemorrhage. Thus, PACNS is on the list of differential diagnoses whenever multifocal hyperintensity is seen on FLAIR images, although it is a diagnosis of exclusion. 12.

[14] However, findings from another study have suggested that non-specific vascular changes in ABRA may be observed when medium-sized arteries are involved. 1. That is, 50% of all cases showed overlap between ICAA and ABRA patterns. [17] Multiple lobar CMBs were found on SWI or T2 images in most patients, but some cases of pathologically confirmed CAA-RI were without CMBs on MRI. The Inflammatory Form of Cerebral Amyloid Angiopathy or "Cerebral Amyloid Angiopathy-Related Inflammation" (CAARI). Impact of A40 and A42 Fibrils on the Transcriptome of Primary Astrocytes and Microglia. When rapid progressive dementia occurs in people over 40 years of age, accompanied by headache, seizures, or focal neurological deficits, with patchy or confluent T2 or FLAIR hyperintensity and evidence of CMBs or cSS, a diagnosis of CAA-RI should be suspected. [12,14,18] The erythrocyte sedimentation rate was increased in 37.5% of patients, while C-reactive protein (CRP) was elevated in 60%. The .gov means its official. 37. 2022 Nov;32(6):e13061. MRI is the modality of choice in assessing these patients as it is able to visualize the characteristic peripheral microhemorrhages of cerebral amyloid angiopathy. 2022 Nov;43(11):6381-6387. doi: 10.1007/s10072-022-06299-y. Liang JW, Zhang W, Sarlin J, Boniece I. There are two recognized pathologically characterized variants: cerebral amyloid angiopathy-related inflammation (CAAri) and A beta-related angiitis (ABRA).

WMH and vasogenic edema accompanied by a mass effect make brain tumors a highly suspected differentiation. 51. 7. However, the average patient is a little younger than in non-inflammatory cerebral amyloid angiopathy and older than those with non-amyloid primary cerebral angiitis 2. The biopsy result revealed intravascular large B-cell lymphoma. The diagnostic efficiency for possible CAA-RI is low, with a specificity of only 68%. Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. [39] One patient with a history of Parkinson's disease (PD) was mistakenly thought to have developed the mental manifestation of PD when he presented with the symptoms of CAA-RI. [58,59] Thus, a variant in SORL1 may lead to dysfunction of SorLA, eventually adding to the risk of CAA-RI. [46,47] A possible explanation for this finding is that, once an immune response to vascular amyloid protein is generated, it affects multiple regions of brain via the spread of antibodies. 4. - "Advancing diagnostic criteria for sporadic cerebral amyloid angiopathy: Study protocol for a multicenter MRI-pathology validation of . Clinical manifestations of cerebral amyloid angiopathy-related inflammation. A 62-year-old man presented with a moderately severe non-radiating frontal headache. 45. Before Federal government websites often end in .gov or .mil. Inflammatory cerebral amyloid angiopathy is an uncommon cerebral amyloid deposition disease, closely related to the far more common non-inflammatory cerebral amyloid angiopathy , and can present as areas of vasogenic edema. [13] Nevertheless, these criteria are still imperfect, as samples included in the validation trial was small. (E) No significant changes with CMBs. Amyloid-related imaging abnormalities in patients with Alzheimer's disease treated with bapineuzumab: a retrospective analysis. A report of 2 cases. At present, the main recommendation is that high-dose glucocorticoids should be used. In addition, when starting the treatment, infection needs to be ruled out first, to avoid pervasion due to corticosteroid therapy. Some of these diseases can be ruled out by T2 MRI or SWI. 64. It also remains unclear what should be done for those diagnosed with possible CAA-RI, and whether they still need to undergo brain biopsy. [9] Cells such as CD3+, CD4+, and CD8+ T lymphocytes, CD20+ B lymphocytes, and CD68+ monocytes, including macrophages (sometimes multinucleated giant cells) in the vessel wall and reactive astrocytes can be found in the surrounding parenchyma. Kirshner et al[8] reported a CAA-RI patient with pathologically confirmed grade III anaplastic astrocytoma. Cerebral amyloid angiopathy is a common small vessel disease in the elderly involving vascular amyloid- deposition. Gera A, Witek N, Bailey M. Pearls & Oy-sters: CAA-related inflammation presents as subacute cognitive decline in a patient with Parkinson disease. This disorder typically responds to steroids but addition of other immune suppressants may be needed in some cases to control the disease. Aimen Moussaddy, Ariel Levy, Daniel Strbian, Sophia Sundararajan, France Berthelet, Sylvain Lanthier. Salvarani C, Brown RD Jr, Calamia KT, Christianson TJ, Huston J 3rd, Meschia JF, et al. Federal government websites often end in .gov or .mil. [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. Inflammatory Disorders of the Central Nervous System Vessels: Narrative Review. However, biopsy is invasive; consequently, most clinically diagnosed cases have been based on clinical and radiological data. Would you like email updates of new search results? Unable to process the form. 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). Cerebral amyloid angiopathy (CAA) is a cerebrovascular disorder caused by the accumulation of cerebral amyloid- (A) in the tunica media and adventitia of leptomeningeal and cortical vessels of the brain.

Genetics and molecular pathogenesis of sporadic and hereditary cerebral amyloid angiopathies. The former represents the inflammatory form of CAA, while the latter is an independent disease or a subtype of PACNS associated with CAA. It may present with symptomatic acute lobar intracerebral hemorrhage (ICH), chronic progressive cognitive decline, transient focal neurological episodes, and subacute cognitive disorder or behavioral changes caused by CAA-related inflammation (CAA-RI). 2022 Nov;43(11):6381-6387. doi: 10.1007/s10072-022-06299-y. Rapid progressive dementia, headache, seizures, or focal neurological deficits, with patchy or confluent hyperintensity on T2 or fluid-attenuated inversion recovery sequences and evidence of strictly lobar microbleeds or cortical superficial siderosis on susceptibility-weighted imaging imply CAA-RI.

J Stroke Cerebrovasc Dis. 1 Introduction of the imaging-based Boston criteria for diagnosis of CAA in the 1990s 2, 3 In addition, CAA is a disease caused by disordered A clearance, and CAA-RI is in fact the body's immune response aimed at clearing A. [14] In addition to A deposition, CAA-RI also demonstrates pronounced perivascular or transmural inflammatory infiltration. Cerebrospinal fluid anti-amyloid- autoantibodies and amyloid PET in cerebral amyloid angiopathy-related inflammation. Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. Kinnecom C, Lev MH, Wendell L, Smith EE, Rosand J, Frosch MP, et al. 63. In addition, it has been observed that immune activation in the parenchyma near the affected blood vessels increased significantly and the A load decreased accordingly. Long-term follow up of patients with mild-to-moderate Alzheimer's disease treated with bapineuzumab in a phase III, open-label, extension study. Besides, the study did not propose a specific treatment or plan for further examination for patients meeting a diagnosis of possible CAA-RI. In particular, amiloid tracers revealed higher retention in CAA patients, correlation with cerebral bleed, the ability to differentiate between CAA and other related conditions (such as Alzheimer's disease) and a correlation with some cerebrospinal fluid biomarkers. Fukasawa R, Shimizu S, Hirose D, Kanetaka H, Umahara T, Obikane H, et al. Table 4. (2013) American Journal of Neuroradiology. However, many patients present with atypical symptoms other than those mentioned above, which may easily lead to an incorrect diagnosis. The asymmetry should not be due to past intracerebral hemorrhage to satisfy this criterion 4. (2019) Frontiers in neurology. Bookshelf Other synonyms used for this entity include cerebral amyloid inflammatory vasculopathy,amyloid angiopathy and granulomatous angiitis of the central nervous system,cerebral amyloid angiitis, primary angiitis of the central nervous system associated with cerebral amyloid angiopathy, and cerebral amyloid angiopathy associated with giant cell arteritis9. In addition, some researchers found that, compared with non-inflammatory CAA, PACNS, and healthy controls, patients with CAA-RI have relatively low levels of A42 and A40 in the CSF. Rarer, inflammatory forms (CAAi) are characterized by the presence of . 11C-PiB PET imaging of encephalopathy associated with cerebral amyloid angiopathy. Moreover, amyloid deposits start in the cortical areas and spread to the hippocampal areas at a later stage [32,33]. 30. 2021 May;73(5):489-495. doi: 10.11477/mf.1416201790. [28] CAA-RI is thought to be a spontaneous ARIA, while ARIA is considered to be iatrogenic CAA-RI. Because of the similarity between CAA-RI and ARIA, the first theory seems unreasonable. [5] Unlike non-inflammatory CAA, acute or subacute onset of cognitive decline or behavioral changes are the most common symptom of CAA-RI. The APOE 4 allele is currently the only confirmed risk factor for CAA-RI. doi: 10.1161/strokeaha.114.005598. 3. Bogner S, Bernreuther C, Matschke J, Barrera-Ocampo A, Sepulveda-Falla D, Leypoldt F, et al. Almost half of those with ARIA-E also developed ARIA-H, with co-located lesions. The work cannot be changed in any way or used commercially without permission from the journal. Keywords: [57]SORL1 encodes a 250-kDa protein called sorting protein-related receptor with A-type repeats (SorLA), which reduces the production and deposition of A peptides by regulating the processing of APP. [68] Other features include seizures, headaches, T2-weighted white matter hyperintense (WMH) lesions on magnetic resonance imaging (MRI), and pathological evidence of inflammation against vascular A, which is the hallmark of CAA.

(C) No enhancement was seen. Epub 2014 Feb 11. Nakaya M, Hashimoto H, Usui G, Sawada K, Shirouzu I, Oshima A, Okubo S, Yamada H, Morikawa T. Cardiovasc Pathol. This case was reminiscent of ANCA-associated vasculitis, although the relationship between proteinase 3-antineutrophil cytoplasmic antibody and the pathogenesis of CAA-RI remains unclear. AD patients who are apolipoprotein E (APOE) 4 gene carriers are more likely to develop ARIA after anti-A treatment,[25,26] in accordance with the findings in CAA-RI. [24] There are three current hypotheses: (1) coexistence of vascular A and vascular inflammation implies that A is a bystander of angiitis; (2) inflammation promotes accumulation of A in the vessel wall; (3) A deposition triggers the inflammatory response. MRA and vessel wall imaging may show medium-sized arteries involved with multifocal stenoses with wall thickening/enhancement 11.
