cerebral amyloid angiopathy related inflammation

Association between immunosuppressive treatment and outcomes of cerebral amyloid angiopathy-related inflammation. 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.

[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. [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.

Long-term follow up of patients with mild-to-moderate Alzheimer's disease treated with bapineuzumab in a phase III, open-label, extension study. In autopsy series, the estimated prevalence of CAA is high (20-40 % in nondemented subjects; 50-60 % in dementia) [1]. An alternative transcript of the Alzheimer's disease risk gene SORL1 encodes a truncated receptor. Nelson T, Leung B, Bannykh S, Shah KS, Patel J, Dumitrascu OM. Imaging Findings of Cerebral Amyloid Angiopathy, A-Related Angiitis (ABRA), and Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Institution 25-Year Experience. Brain MRI, particularly FLAIR and T2/SWI sequences, is the most important imaging modality for the identification of patients suspected of CAA-RI. [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. In humans, cerebral amyloid angiopathy and related vascular dysfunction are suggested to affect small vessels in the cortical areas [30,31]. You may be trying to access this site from a secured browser on the server. [22,31] In fact, both ICAA and ABRA can present with or without granulomatous inflammation. Epub 2022 Aug 5. A clinico-radiological study of cerebral amyloid angiopathy-related inflammation. Salloway SP, Sperling R, Fox NC, Sabbagh MN, Honig LS, Porsteinsson AP, et al. [13] For patients diagnosed with probable CAA-RI by means of these criteria, immunosuppressive therapy can be given empirically to avoid brain biopsy. 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. The diagnostic criteria for possible or probable inflammatory cerebral amyloid angiopathy require at least one of the following clinical features that are not directly attributable to an acute intracerebral hemorrhage4: Some patients also present with hallucinations 2. 66.

Moreover, the efficacy of treatment was evaluated by observational studies; consequently, more clinical trials and even randomized clinical trials are required. Table 4. Cerebral amyloid angiopathy (CAA) is an important cause of cognitive impairment and spontaneous intracerebral hemorrhage in the elderly. [14] Based on the criteria of leptomeningeal enhancement, the sensitivity and specificity of recognizing CAA-RI from CAA patients are reported to be 70.4% and 92.6%, respectively. 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. 2022 Nov;32(6):e13061. 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. 71. Besides, the study did not propose a specific treatment or plan for further examination for patients meeting a diagnosis of possible CAA-RI. National Library of Medicine 12.

Because of the similarity between CAA-RI and ARIA, the first theory seems unreasonable. 64. 60. Kirshner HS, Bradshaw M. The inflammatory form of cerebral amyloid angiopathy or cerebral amyloid angiopathy-related inflammation (CAARI). 31. In addition, there is a need to determine more biomarkers by which to modify the diagnostic criteria and further improve diagnostic efficiency. [10] The carriage rate in non-inflammatory CAA patients was only 5.1%,[10] and it is rarely seen in healthy people or stroke patients. The use of glucocorticoids and immunosuppressants improves prognosis. In fact, in a subgroup of patients, spontaneous remission is encountered 1. Gera A, Witek N, Bailey M. Pearls & Oy-sters: CAA-related inflammation presents as subacute cognitive decline in a patient with Parkinson disease. Sengoku R, Matsushima S, Murakami Y, Fukuda T, Tokumaru AM, Hashimoto M, et al. Some authors are consistent with the terms we have used here, while some call the two subtypes CAA-RI and ABRA. Andersen OM, Rudolph IM, Willnow TE. Cerebral amyloid angiopathy. 2016 May;95(20):e3613. [28] This strongly suggests that an immune response to A is responsible for CAA-RI. [14] However, findings from another study have suggested that non-specific vascular changes in ABRA may be observed when medium-sized arteries are involved. 70. and transmitted securely.

[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. Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. 2. 2022 Nov 14;11(22):6731. doi: 10.3390/jcm11226731. Cerebral amyloid angiopathy-related inflammation (CAA-ri) is an unusual cause of encephalopathy, seizures and focal neurological deficits.1 2 We report three cases of CAA-ri with minimal symptoms but striking and dynamically evolving brain MRI findings.

[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. [32] In a systematic review, of the 142 cases with available data, 27.5% presented with both perivascular inflammation and vasculitis with granuloma formation, which is the most common pathological pattern. [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. Amyloid-Beta Related Angitiis and Reversible Cerebral Vasoconstriction Syndrome: A Case Report (P6.057). 8. [18] No difference in outcome was found between patients receiving mono-therapy of corticosteroid and patients receiving a combination of immunosuppressant and corticosteroid therapy. Clinical manifestations of cerebral amyloid angiopathy-related inflammation. The gold standard for diagnosis is autopsy or brain biopsy. The resultant vascular fragility tends to manifest in normotensive elderly patients as lobar intracerebral haemorrhage. The diagnostic efficiency for possible CAA-RI is low, with a specificity of only 68%. DiFrancesco JC, Brioschi M, Brighina L, Ruffmann C, Saracchi E, Costantino G, et al.

[47,60] In the future, the significance of these indicators for the differential diagnosis of CAA-RI mimics should be studied. Salvarani C, Morris JM, Giannini C, Brown RD Jr, Christianson T, Hunder GG. The diagnostic criteria for possible or probable inflammatory cerebral amyloid angiopathy require age 40 years 4. [62,63] Thus, it is very important to recognize the clinical and radiological properties of CAA-RI and bear some differential diagnoses in mind; those substantial differential diagnoses should be ruled out before CAA-RI was diagnosed. FOIA 67. 35. doi: 10.1097/MD.0000000000003613. Chung KK, Anderson NE, Hutchinson D, Synek B, Barber PA. Cerebral amyloid angiopathy related inflammation: three case reports and a. Reid AH, Maloney AF. MeSH [10,42,43] SWI is considered to be more reliable than T2 imaging, with greater reliability and sensitivity for detection of CMBs. Unauthorized use of these marks is strictly prohibited. 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. Therefore, other biomarkers are needed to enrich the criteria. Thus, other differential diagnoses should be carefully ruled out. [4] With the development of imaging technology, more clinical silent patients are identified by the classic imaging abnormalities, including multiple strictly lobar cerebral microbleeds (CMBs), cortical superficial siderosis (cSS) or cortical subarachnoid hemorrhage, and cortical atrophy.[3]. Abeta-related angiitis: primary angiitis of the central nervous system associated with cerebral amyloid angiopathy. 46. 40. Tumors including primary central nervous system lymphomas and metastases should be taken into consideration when making a diagnosis in such patients. Early diagnosis and timely treatment may improve prognosis. Check for errors and try again. Since there is no A deposition in the blood vessels supplying the spinal cord, symptoms of myelopathy have not been reported in ICAA and ABRA; thus, PACNS is a more likely diagnosis when symptoms involving the spinal cord occur. Unable to load your collection due to an error, Unable to load your delegates due to an error. Please enable it to take advantage of the complete set of features! 58. Your message has been successfully sent to your colleague. [44,45] However, sometimes the burden of CMBs is so obvious that hypointense lesions seen on SWI can also be identified on T2 or FLAIR images. Pseudotumoral presentation of cerebral amyloid angiopathy-related inflammation. In contrast to CAA, which is currently without effective treatment, most studies have shown that empirical high-dose corticosteroids with or without additional immunosuppressive therapy can mitigate symptoms and imaging abnormalities and can improve the prognosis of CAA-RI. Kinnecom C, Lev MH, Wendell L, Smith EE, Rosand J, Frosch MP, et al. Additionally, although there is considerable overlap, inflammatory cerebral amyloid angiopathy should be distinguished from amyloid-related imaging abnormalities (ARIA)that are seen in the setting of treatment with novel amyloid-lowering therapies such as monoclonal antibodies 13. Epub 2019 May 25. Epub 2014 Feb 11. 11C-PiB PET imaging of encephalopathy associated with cerebral amyloid angiopathy. BMC Neurol. Beta-amyloid 42 is a more effective reductant than beta-amyloid 40. However, many patients present with atypical symptoms other than those mentioned above, which may easily lead to an incorrect diagnosis. Amyloid PET is also unavailable in most hospitals in China. A Report of 2 Cases. [22] The mainstream view is that granulomatous inflammation is the pathological hallmark of ABRA, but not of ICAA. Cerebral amyloid angiopathy (CAA) is a type of cerebrovascular disorder characterized by the accumulation of amyloid within the leptomeninges and small/medium-sized cerebral blood vessels. 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. 2016 May;95(20):e3613. [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. Saliou V, Ben Salem D, Ognard J, Guellec D, Marcorelles P, Rouhart F, et al. That is, 50% of all cases showed overlap between ICAA and ABRA patterns. [61] Despite this, negative brain biopsy findings are insufficient to exclude the diagnosis of CAA-RI, because of the segmental distribution of pathological changes.

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. 65. Thomas Tropea, Prasad Shirvalkar, Krithiga Sekar, Kyung-Wha Kim, Apostolos Tsiouris, Ehud Lavi, Alan Segal. A significant proportion of patients respond readily to treatment with corticosteroids, with or without a cytostatic agent,with improvement evident within a week or two of commencement of treatment. 45. Accessibility Similar clinical processes and radiological changes of CAA-RI appear in amyloid-related imaging abnormalities (ARIA), initially during the clinical trial of bapineuzumab, the monoclonal antibody for AD, and later in that of other amyloid modification therapies.

There are two major types of CAA: one is hereditary CAA, which is associated with Down syndrome or mutations in the A protein precursor (APP) gene or presenilin gene,[1] and the other one is age-related sporadic CAA. 2016;51(2):525-32. doi: 10.3233/JAD-151036. doi: 10.1097/MD.0000000000003613. [2,1719] In addition, some researchers still believe that CAA-RI/ICAA and ABRA are two different disease entities. The mechanism underlying CAA-RI remains unclear. The site is secure. Imaging Findings of Cerebral Amyloid Angiopathy, A-Related Angiitis (ABRA), and Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Institution 25-Year Experience. 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]. Hence, in such cases, close follow-up should be performed. Abstract. However, anticoagulation was later suspended due to cerebral hemorrhage, and the patient was finally diagnosed with CAA-RI. Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Center Experience and a Literature Review. 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). Disclaimer. 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. Immunosuppressants can be administered in cases showing no response to glucocorticoids or for preventing recurrence. Salvarani C, Hunder GG, Morris JM, Brown RD, Christianson T, Giannini C. A-related angiitis: comparison with CAA without inflammation and primary CNS vasculitis. The possible mechanism is that APOE 4 increases A deposition, and has a pro-inflammatory effect. Other differential diagnoses include viral or autoimmune encephalitis, cerebral venous thrombosis, acute disseminated encephalomyelitis (ADEM), Hashimoto encephalopathy, neurosarcoidosis, and acute toxic-metabolic leukoencephalopathy.
