cerebral amyloid angiopathy related inflammation

2022 Nov 19;10(11):2982. doi: 10.3390/biomedicines10112982. 57. Medicina (Kaunas). Phrases such as CAA associated with inflammation, CAA-RI, ICAA, and ABRA are used interchangeably. Cerebral amyloid angiopathy related inflammation with prominent meningeal involvement. The former represents the inflammatory form of CAA, while the latter is an independent disease or a subtype of PACNS associated with CAA. PMC Immune activation in amyloid--related angiitis correlates with decreased parenchymal amyloid- plaque load. Clipboard, Search History, and several other advanced features are temporarily unavailable. Gera A, Witek N, Bailey M. Pearls & Oy-sters: CAA-related inflammation presents as subacute cognitive decline in a patient with Parkinson disease. Tetsuka S, Hashimoto R. Slightly symptomatic cerebral amyloid angiopathy-related inflammation with spontaneous remission in four months. [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. The clinical manifestations of PACNS can also mimic the pattern of CAA-RI. Teaching neuro: cerebral amyloid angiopathy-related inflammation presenting with isolated leptomeningitis. (2015) Current neurology and neuroscience reports. [47,60] In the future, the significance of these indicators for the differential diagnosis of CAA-RI mimics should be studied. Kinnecom C, Lev MH, Wendell L, Smith EE, Rosand J, Frosch MP, et al. Sakai K, Hayashi S, Sanpei K, Yamada M, Takahashi H. Multiple cerebral infarcts with a few vasculitic lesions in the chronic stage of cerebral amyloid angiopathy-related inflammation. The incidence of multiple lobar CMBs, as well as the total number of CMBs is significantly higher in CAA-RI patients. 2022 Nov;32(6):e13061. It is worth noting that CAA-RI is a diagnosis by exclusion. (2019) Frontiers in neurology. [28] This strongly suggests that an immune response to A is responsible for CAA-RI. Since the treatment does not obviously harm the tumor, the response of the lesion to the given treatment can be observed to figure out whether it deteriorates as time goes by. -, Reid AH, Maloney AF. A 77-year-old female experienced light-headedness during walking and mild ataxic gait without any other objective neuropsychological deficits. [33] Findings from several systematic reviews have shown that there is no obvious gender difference, but a slight male predominance was observed. 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. 2016YFC1300500-505). In addition, there is a need to determine more biomarkers by which to modify the diagnostic criteria and further improve diagnostic efficiency. Yamada M. Cerebral amyloid angiopathy: emerging concepts. 33. (2016) Medicine. Mandal J, Chung SA. The asymmetry should not be due to past intracerebral hemorrhage to satisfy this criterion 4. Cerebral amyloid angiopathy-related inflammation. These cases emphasize that CAA-RI is a diagnosis by exclusion. 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. 60. . Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. Amyloid can be confirmed when the Congo red-stained section shows green birefringence under polarized light. A engulfed in macrophages can be observed at times. HHS Vulnerability Disclosure, Help doi: 10.1097/WCO.0000000000000510. [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. Biopsy obtained from the white matter showed no evidence of inflammation in one case. Corticosteroid therapy in a patient with cerebral amyloid angiopathy-related inflammation. Discussion This report of neurologic autoimmunity in a patient receiving sitravatinib opens new lines of inquiry into the pathophysiology of CAA-ri. It would be more difficult to identify patients who also have a history of tumors. First, ABRA has the same radiological characteristics as ICAA, which are not common in PACNS. 41. 50. Federal government websites often end in .gov or .mil. The accuracy of the standard was verified, and yielded a sensitivity and specificity of 82% and 97% diagnosing probable CAA-RI, respectively. 3. Amyloid beta-related angiitis--a case report and comprehensive review of literature of 94 cases. Salvarani C, Morris JM, Giannini C, Brown RD, Christianson T, Hunder GG. The gold standard for diagnosis is autopsy or brain biopsy. 24. [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. Nelson T, Leung B, Bannykh S, Shah KS, Patel J, Dumitrascu OM. modify the keyword list to augment your search. Primary angiitis of the central nervous system. sharing sensitive information, make sure youre on a federal However, the average patient is a little younger than in non-inflammatory . [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. Traschtz A, Tzaridis T, Penner AH, Kuchelmeister K, Urbach H, Hattingen E, et al. (E) No significant changes with CMBs. Reid AH, Maloney AF. Reid and Maloney first described CAA with vascular inflammation in a patient with AD in 1974, and subsequent cases were reported. Nakaya M, Hashimoto H, Usui G, Sawada K, Shirouzu I, Oshima A, Okubo S, Yamada H, Morikawa T. Cardiovasc Pathol. 14. (B) Strictly lobar, MeSH 51 (2): 525-32. Key Diagnostic Features: Cerebral amyloid angiopathy-related inflammation (CAA-ri) is characterized by sub-acute confusion, progressive cognitive decline, seizure or headaches; reversible focal subcortical and/or cortical T2 hyperintensities on magnetic resonance imaging (MRI); and neuropathological evidence of cerebral amyloid angiopathy (CAA) and associated vascular or perivascular inflammation [1-3]. Another option is to follow the patient up closely. Cerebral amyloid angiopathy (CAA) is a common small vessel disease characterized by the deposition of amyloid (A) protein mainly in the media and adventitia of small- and medium-sized leptomeningeal and cortical blood vessels. 9. 61. 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. 8.

Morris, M. Grundman. Thus, PACNS is on the list of differential diagnoses whenever multifocal hyperintensity is seen on FLAIR images, although it is a diagnosis of exclusion. [28] CAA-RI is thought to be a spontaneous ARIA, while ARIA is considered to be iatrogenic CAA-RI. 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. A Report of 2 Cases. Szpak GM, Lewandowska E, Sliwiska A, Stpie T, Tarka S, Mendel T, et al. 2022 Dec 3;22(1):449. doi: 10.1186/s12883-022-02979-6. There is currently no long-term follow-up cohort to establish prognosis, and differences in prognoses associated with different therapies for different subtypes are worth investigating. Immunosuppressive therapy is effective both during initial presentation and in relapses. Reduction of microbleeds by immunosuppression in a patient with A-related vascular inflammation. Kotsenas AL, Morris JM, Wald JT, Parisi JE, Campeau NG. In order to make a diagnosis before histopathology, Chung et al[12] proposed the Boston criteria using clinicoradiological data in 2011.

National Library of Medicine 28. 9. If only routine sequences are performed, it is easy to mistake WMH as the only image manifestation and consequently delay diagnosis and treatment. [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. 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-related inflammation: a potentially reversible cause of dementia with characteristic imaging findings. In another case, the patient had clinical and imaging characteristics of CAA-RI, but because of bicytopenia and an increase in CRP and lactate dehydrogenase, lymphoma was suspected. [15] In fact, these two types sometimes do coexist. and transmitted securely. 62. 15 (8): 54. In addition, the treatment of infection and other comorbidities should be considered in such cases. Nakaya M, Hashimoto H, Usui G, Sawada K, Shirouzu I, Oshima A, et al. However, biopsy is invasive; consequently, most clinically diagnosed cases have been based on clinical and radiological data. 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. doi: 10.1097/MD.0000000000003613. Hence, in such cases, close follow-up should be performed. [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. 48. Therefore, other biomarkers are needed to enrich the criteria. 16. 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. Epub 2022 Aug 5. 65. However, the prognosis of most untreated patients is poor. Cerebral amyloid angiopathy-related inflammation: imaging findings and clinical outcome. There is currently no study giving recommendations on the choice of medication, dosage, and the time span of treatment. 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. Federal government websites often end in .gov or .mil. (A) Confluent WMH. 2. The resultant vascular fragility tends to manifest in normotensive elderly patients as lobar intracerebral haemorrhage. Tumors including primary central nervous system lymphomas and metastases should be taken into consideration when making a diagnosis in such patients. Medicine (Baltimore).

An alternative transcript of the Alzheimer's disease risk gene SORL1 encodes a truncated receptor. 2022 Oct 13;58(10):1446. doi: 10.3390/medicina58101446. There have been few epidemiological studies on CAA-RI. 45. In the remainder, which accounts for 60% of all affected individuals, even with treatment severe disability or death are encountered 2. 37. Biomedicines. 6. [14,29] Finally, in terms of clinical manifestations and prognosis, there was no difference between the two pathological subtypes of CAA-RI. 4. It also remains unclear what should be done for those diagnosed with possible CAA-RI, and whether they still need to undergo brain biopsy. - "Advancing diagnostic criteria for sporadic cerebral amyloid angiopathy: Study protocol for a multicenter MRI-pathology validation of . Still others refer to only cerebral amyloid angiopathy-related inflammation alone 1,4,5,10or amyloid -related angiitis alone 7without mention of the other. Thus, amyloid positron emission tomography (PET) might be important for the diagnosis of CAA-RI, by showing sites with markedly elevated amyloid deposition.[11,52,53]. There are two recognized pathologically characterized variants: cerebral amyloid angiopathy-related inflammation (CAAri) and A beta-related angiitis (ABRA). Moreover, ABRA was considered to be different from ICAA because it has the same vascular destructive pathological changes as PACNS. 2. 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. [22] The mainstream view is that granulomatous inflammation is the pathological hallmark of ABRA, but not of ICAA. Vonsattel grading for CAA severity on neuropathology samples. Salvarani C, Morris JM, Giannini C, Brown RD Jr, Christianson T, Hunder GG. [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. Yeh SJ, Tang SC, Tsai LK, Jeng JS. Medicine (Baltimore). J Stroke 2015; 17:1730. Prodromal Alzheimer's disease presenting as cerebral amyloid angiopathy-related inflammation with spontaneous amyloid-related imaging abnormalities and high cerebrospinal fluid anti-A autoantibodies. Our clinical experience also supports this conclusion [Figure 1]. (B) Strictly lobar CMBs. The presence of symmetric white matter lesions that extend to the immediately subcortical white matter would only meet the criteria for "possible" inflammatory cerebral amyloid angiopathy 4. The .gov means its official. However, biopsy is invasive; consequently, most clinically diagnosed cases have been based on clinical and radiological data. 5. Salloway SP, Sperling R, Fox NC, Sabbagh MN, Honig LS, Porsteinsson AP, et al. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). [14] However, findings from another study have suggested that non-specific vascular changes in ABRA may be observed when medium-sized arteries are involved. Neurology 2013; 81:15961603. [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]). 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. 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. 11. CAARI, also called amyloid--related angiitis, is a rare form of cerebral amyloid angiopathy with a predominantly vascular inflammation or angiitis. 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. 2022 Nov;43(11):6381-6387. doi: 10.1007/s10072-022-06299-y.

Keywords: Unable to load your collection due to an error, Unable to load your delegates due to an error. The diagnostic criteria for possible or probable inflammatory cerebral amyloid angiopathy require age 40 years 4. Epub 2014 Feb 11. 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. Renard D, Collombier L, Demattei C, Wacongne A, Charif M, Ayrignac X, et al. Disclaimer. Would you like email updates of new search results? Wolters Kluwer Health 20. Some cases presented with involuntary movement,[35,36] while others had systemic diseases,[14] cerebral hernia caused by severe edema,[37] uveitis,[21] multiple malignancies,[14,15,38] extracranial vasculitis, or vascular dysplasia at baseline. [13] For patients diagnosed with probable CAA-RI by means of these criteria, immunosuppressive therapy can be given empirically to avoid brain biopsy. Thirteen percent of patients were affected with some forms of visual impairment. (2015) Stroke. Please enable it to take advantage of the complete set of features! Inflammatory cerebral amyloid angiopathy. [19] Spontaneous remission has been reported in some cases,[7,71] the fundamentals of which are not yet known. Clinical Presentation: Patients typically present with seizures, headache, and strokelike episodes, along with an acute or subacute decline in cognitive status. [18] No difference in outcome was found between patients receiving mono-therapy of corticosteroid and patients receiving a combination of immunosuppressant and corticosteroid therapy. 70. [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. [17] While another systematic review showed that the functional outcome of most patients was not ideal.

However, biopsy is invasive; consequently, some criteria for the diagnosis of CAA-RI have been based on clinical and radiological data. 17. It may also present with cognitive impairments, incidental . Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. In fact, in a subgroup of patients, spontaneous remission is encountered 1. [72] It is worth noting that this case involved a patient who had been using immunosuppressive agents. Amyloid-Beta Related Angitiis and Reversible Cerebral Vasoconstriction Syndrome: A Case Report (P6.057). Renard D, Tatu L, Collombier L, Wacongne A, Ayrignac X, Charif M, Boukriche Y, Chiper L, Fourcade G, Azakri S, Gaillard N, Mercier E, Lehmann S, Thouvenot E. J Alzheimers Dis. Perivascular and vascular inflammatory patterns without granulomas accounted for 22.5% of cases. DiFrancesco JC, Brioschi M, Brighina L, Ruffmann C, Saracchi E, Costantino G, et al. 10. Because of the similarity between CAA-RI and ARIA, the first theory seems unreasonable. 64. Risk factor SORL1: from genetic association to functional validation in Alzheimer's disease. Your message has been successfully sent to your colleague. Dear Sirs, Cerebral amyloid angiopathy (CAA) causes intracerebral haemorrhages and is associated with cognitive impairment and Alzheimer's disease. Cerebral amyloid angiopathy is unrelated to generalized amyloidosis. J Alzheimers Dis. About 60% of patients died or were severely disabled after immunotherapy, and there was no statistically significant difference in terms of prognosis between the two pathological types. 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) []. Keyword Highlighting 56. In the vast majority of cases (90%), microhemorrhages are present 1,2. If the brain biopsy result is negative, but the patient meets the clinicoradiological diagnostic criteria, the course of action remains uncertain. 72. CAA-RI is now widely recognized as a relatively rare and aggressive subtype of CAA with diverse clinical presentations and characteristic radiological findings. 44.

Cerebral amyloid angiopathy-related inflammation: current status and future implications. Acute or subacute onset of cognitive decline or behavioral changes is the most common symptom of CAA-RI. 35. A report of 2 cases. Although tumors, neurosarcoidosis, Hashimoto encephalopathy, ADEM, or PACNS are unlikely to be aggravated by empirical usage of corticosteroids, the treatment may obscure the diagnosis of those diseases. [58,59] Thus, a variant in SORL1 may lead to dysfunction of SorLA, eventually adding to the risk of CAA-RI. Brashear, H.M. Arrighi, K.A. PACNS usually occurs in younger patients (mean age, 45 years), while CAA-RI is common in slightly older people. Angiography does not reveal evidence of vasculitis involving the large- or medium-sized vessels 6. This study was supported by a grant from the National Key Research and Development Program of China (No. Many diseases with similar clinical manifestations should be carefully ruled out. The Karolinska Imaging Dementia Study. Please try after some time. By definition, CAA is characterized by vessel wall amyloid deposits. Please enable scripts and reload this page. Clinicians should have a comprehensive understanding of the disease and order an MRI with multiple sequences, including T2 or SWI, in patients with suspected CAA-RI, particularly in those cases whose T2/FLAIR images show hypointense dots. The use of glucocorticoids and immunosuppressants improves prognosis. This is in most cases a non-inflammatory age-related condition that is associated with cerebral hemorrhage, infarcts, leukoencephalopathy and dementia. [2] CAA is clinically diverse. Many diseases with similar clinical manifestations should be carefully ruled out. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. The distribution of CMBs does not follow the regional pattern of occipital dominance in non-inflammatory CAA. -, Yeh SJ, Tang SC, Tsai LK, Jeng JS. Almost half of those with ARIA-E also developed ARIA-H, with co-located lesions.
