Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Center Experience and a Literature Review. CAA is an important cause of lobar intracerebral hemorrhage in older adults [ 1,2 ]. Vonsattel grading for CAA severity on neuropathology samples. [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. Third, A was engulfed by macrophages expressing MHC class II antigens near CD4+ T cells, suggesting that A plays a pathogenic role in inducing inflammation in ABRA. Due to the potentially reversible WMH in ICAA,[43] when clinical manifestations are present and findings on conventional MRI sequences are suggestive, it must be distinguished from PRES, which also has the characteristic of bilateral confluent T2 WMH, but is often associated with hypertension or other conditions. 10. [2] CAA is clinically diverse. In order to make a diagnosis before histopathology, Chung et al[12] proposed the Boston criteria using clinicoradiological data in 2011. Discussion This report of neurologic autoimmunity in a patient receiving sitravatinib opens new lines of inquiry into the pathophysiology of CAA-ri. Yamada M. Cerebral amyloid angiopathy: emerging concepts. Careers. 2022 Nov 19;10(11):2982. doi: 10.3390/biomedicines10112982. Brain Nerve. Morris, M. Grundman. [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. Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. [11] The most commonly used immunosuppressants are cyclophosphamide (33.9%), azathioprine (5.0%), mycophenolate mofetil (5.0%), methotrexate, immunoglobulin, and so on. [Cerebral Amyloid Angiopathy-Related Inflammation/Vasculitis]. [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. In addition to clinical symptoms and image findings, detection of genotypes, CSF biomarkers, such as anti-A autoantibodies, and amyloid PET may also provide diagnostic evidence and serve as tools for evaluating treatment efficacy. 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. Salvarani C, Hunder GG, Morris JM, Brown RD, Christianson T, Giannini C. A-related angiitis: comparison with CAA without inflammation and primary CNS vasculitis. 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. Because of the similarity between CAA-RI and ARIA, the first theory seems unreasonable. 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. 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. Inflammatory cerebral amyloid angiopathy. Long-term follow up of patients with mild-to-moderate Alzheimer's disease treated with bapineuzumab in a phase III, open-label, extension study. Sugihara S, Ogawa A, Nakazato Y, Yamaguchi H. Cerebral beta amyloid deposition in patients with malignant neoplasms: its prevalence with aging and effects of radiation therapy on vascular amyloid. [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. Many diseases with similar clinical manifestations should be carefully ruled out. Ronsin S, Deiana G, Geraldo AF, Durand-Dubief F, Thomas-Maisonneuve L, Formaglio M, et al. 41 (3): 446-448.

Primary central nervous system vasculitis: comparison of patients with and without cerebral amyloid angiopathy. 4. [61] Despite this, negative brain biopsy findings are insufficient to exclude the diagnosis of CAA-RI, because of the segmental distribution of pathological changes.

PACNS usually occurs in younger patients (mean age, 45 years), while CAA-RI is common in slightly older people. 44. First, ABRA has the same radiological characteristics as ICAA, which are not common in PACNS. [13] Nevertheless, these criteria are still imperfect, as samples included in the validation trial was small. See this image and copyright information in PMC. 72. doi: 10.1097/WCO.0000000000000510.

[17] While another systematic review showed that the functional outcome of most patients was not ideal. The accuracy of the standard was verified, and yielded a sensitivity and specificity of 82% and 97% diagnosing probable CAA-RI, respectively. 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. Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. The use of glucocorticoids and immunosuppressants improves prognosis.

CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. Cerebral amyloid angiopathy is often asymptomatic, which can cause dementia, intracranial hemorrhage, or transient neurological events. Dear Sirs, Cerebral amyloid angiopathy (CAA) causes intracerebral haemorrhages and is associated with cognitive impairment and Alzheimer's disease. Growing numbers of patients have been reported with vascular inflammation associated with advanced cerebral amyloid angiopathy (59; 150). However, many patients present with atypical symptoms other than those mentioned above, which may easily lead to an incorrect diagnosis. Immunosuppressive therapy is effective both during initial presentation and in relapses. doi: 10.1097/MD.0000000000003613. Data is temporarily unavailable. American journal of neuroradiology. Piazza F, Greenberg SM, Savoiardo M, Gardinetti M, Chiapparini L, Raicher I, et al. [58,59] Thus, a variant in SORL1 may lead to dysfunction of SorLA, eventually adding to the risk of CAA-RI.

Anti-amyloid beta autoantibodies in cerebral amyloid angiopathy-related inflammation: implications for amyloid-modifying therapies. Thus, in this review, we present the main pathological, clinical, neuroimaging, therapeutic, and prognostic features and the diagnostic criteria of CAA-RI to shed some light on its clinical practice, and then discuss issues that remain unresolved. 49.

Table 4. The clinical presentation is usually acute or subacute 1,2, but may be chronic4. Giant cell arteritis and arteriolitis associated with amyloid angiopathy in an elderly mongol. Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. ADVERTISEMENT: Supporters see fewer/no ads. [13] For patients diagnosed with probable CAA-RI by means of these criteria, immunosuppressive therapy can be given empirically to avoid brain biopsy. doi: 10.1111/bpa.13061.

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. [14] However, findings from another study have suggested that non-specific vascular changes in ABRA may be observed when medium-sized arteries are involved. [14] Previous studies have revealed that, compared with multiple sclerosis and healthy people, anti-A autoantibodies in the CSF of CAA-RI patients increased during the acute phase, which is consistent with what was observed in ARIA, supporting the aforementioned hypothesis of an A-induced immune response. [2527] ARIA is also divided into two categories: ARIA-E, which manifests as focal or confluent vasogenic edema on fluid-attenuated inversion recovery (FLAIR) sequence images, and ARIA-H, characterized by CMBs or cSS on T2-weighted gradient-echo/susceptibility-weighted imaging (SWI) sequence scans, corresponding to the image hallmarks of CAA-RI. Acute or subacute onset of cognitive decline or behavioral changes is the most common symptom of CAA-RI. Miller-Thomas MM, Sipe AL, Benzinger TL et-al. 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. Leptomeningeal contrast enhancement is seen in approximately half of patients 1,2. Cerebral amyloid angiopathy (CAA)related inflammation (CAA-RI) affects brain parenchyma, but rarely involves leptomeninges, a likely immunogenic consequence of -amyloid peptide expressed in the walls of small and medium sized cerebral vessels. 95 (20): e3613. Cerebral amyloid angiopathy-related inflammation. Epub 2015 Jul 2. DiFrancesco JC, Brioschi M, Brighina L, Ruffmann C, Saracchi E, Costantino G, et al. 73 (2): 197-202. The site is secure. 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. 11C-PiB PET imaging of encephalopathy associated with cerebral amyloid angiopathy. 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. The resultant vascular fragility tends to manifest in normotensive elderly patients as lobar intracerebral haemorrhage. [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. Case of cerebral amyloid angiopathy-related inflammation - is the absence of cerebral microbleeds a good prognostic sign? Objective. The diagnostic criteria for possible or probable inflammatory cerebral amyloid angiopathy require age 40 years 4. Chung KK, Anderson NE, Hutchinson D, Synek B, Barber PA.

Immune activation in amyloid--related angiitis correlates with decreased parenchymal amyloid- plaque load. Ann Neurol 2013; 73:449. Cerebral amyloid angiopathy (CAA) is a condition in which proteins called amyloid build up on the walls of the arteries in the brain. Kirshner HS, Bradshaw M. The Inflammatory Form of Cerebral Amyloid Angiopathy or "Cerebral Amyloid Angiopathy-Related Inflammation" (CAARI). [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. It is generally recommended that brain biopsy should be performed from an area with abnormal radiologic manifestations, preferably at a lesion in the cortex or leptomeninges. 51 (2): 525-32. doi: 10.1212/WNL.0b013e3182a9f545. 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. SWI or T2: which MRI sequence to use in the detection of cerebral microbleeds? [6,66] In addition, these two conditions may be present concurrently. Wolters Kluwer Health MeSH Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. 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. Inflammatory Cerebral Amyloid Angiopathy, Amyloid-Related Angiitis, and Primary Angiitis of the Central Nervous System. It also remains unclear what should be done for those diagnosed with possible CAA-RI, and whether they still need to undergo brain biopsy. 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. An alternative transcript of the Alzheimer's disease risk gene SORL1 encodes a truncated receptor. 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. In addition, there is a need to determine more biomarkers by which to modify the diagnostic criteria and further improve diagnostic efficiency. 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. Terminology (2016) Journal of Alzheimer's disease : JAD. Moosavi B, Torres C, Jansen G. Case 232: Amyloid -related Angiitis. [5] Unlike non-inflammatory CAA, acute or subacute onset of cognitive decline or behavioral changes are the most common symptom of CAA-RI. 50. Chinese Medical Journal134(6):646-654, March 20, 2021. 14. doi: 10.1097/MD.0000000000003613. (C) No enhancement was seen. [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. Clinical Presentation: Patients typically present with seizures, headache, and strokelike episodes, along with an acute or subacute decline in cognitive status. [14] The dosage used is based on individual selection. 66. 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. While changes are typically confined to the subcortical white matter, the involvement of the cortex is also encountered and predisposes to seizures 1,2. WMHs sometimes extend to the cortex with a mass effect showing hyperintensity in maps of apparent diffusion coefficient suggesting vasogenic edema. Brain MRI, particularly FLAIR and T2/SWI sequences, is the most important imaging modality for the identification of patients suspected of CAA-RI. Cerebral amyloid angiopathy. Abstract. Another option is to follow the patient up closely. A 77-year-old female experienced light-headedness during walking and mild ataxic gait without any other objective neuropsychological deficits.
