A Narrative Review of the Neurological Manifestations of Human Adenosine Deaminase 2 Deficiency. J Clin Immunol 2023; 43:1916-1926. [PMID: 37548813 PMCID: PMC10661818 DOI: 10.1007/s10875-023-01555-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Accepted: 07/14/2023] [Indexed: 08/08/2023]
Abstract
Deficiency of human adenosine deaminase type 2 (DADA2) is a complex systemic autoinflammatory disorder characterized by vasculopathy, immune dysregulation, and hematologic abnormalities. The most notable neurological manifestations of DADA2 are strokes that can manifest with various neurological symptoms and are potentially fatal. However, neurological presentations can be diverse. We here present a review of the neurological manifestations of DADA2 to increase clinical awareness of DADA2 as the underlying diagnosis. We reviewed all published cases of DADA2 from 1 January 2014 until 19 July 2022 found via PubMed. A total of 129 articles describing the clinical features of DADA2 were included in the analysis. Six hundred twenty-eight patients diagnosed with DADA2 were included in the review. 50.3% of patients had at least signs of one reported neurological event, which was the initial or sole manifestation in 5.7% and 0.6%, respectively. 77.5% of patients with neurological manifestations had at least signs of one cerebrovascular accident, with lacunar strokes being the most common and 35.9% of them having multiple stroke episodes. There is a remarkable predilection for the brain stem and deep gray matter, with 37.3% and 41.6% of ischemic strokes, respectively. Other neurological involvement included neuropathies, focal neurological deficits, ophthalmological findings, convulsions, and headaches. In summary, neurological manifestations affect a significant proportion of patients with DADA2, and the phenotype is broad. Neurological manifestations can be the first and single manifestation of DADA2. Therefore, stroke, encephalitis, posterior reversible encephalopathy syndrome, mononeuropathy and polyneuropathy, and Behçet's disease-like presentations should prompt the neurologist to exclude DADA2, especially but not only in childhood.

Abstract
Abstract
Background
Familial Mediterranean Fever (FMF) is a periodic auto-inflammatory disease with multiple systemic manifestations. This study aims to describe the various musculoskeletal and neurological manifestations in a cohort of Egyptian FMF patients and to evaluate their relation to the different Mediterranean fever gene (MEFV) mutations.
Results
This study involved 145 FMF patients, of them 62.1% were females and 31.7% were of the pediatric age. All involved patients had homozygous MEFV gene mutation. The presenting manifestation in 71.9% of these patients was abdominal pain followed by musculoskeletal manifestations in 35.2% of them. 38.6 % of the involved patients had arthritis during the period of follow-up. Monoarthritis was the most frequent pattern of arthritis. Arthralgia was present in 96.6% of the studied patients. Myalgia was present in 19.3% of the studied patients especially involving the lower limb muscles with one case of protracted febrile myalgia. Neurological manifestations were present in about 86.9 % of patients with vertigo, paresthesia, and seizures as the most common. Five major MEFV gene mutations were found in most of the studied patients (135 patients): M694V, M680I, E148Q, V726A, and M694I. When a comparative study was done between these five major mutations according to the age of onset of the symptoms, different musculoskeletal and neurological manifestations, ESR, serum amyloid level and dose of colchicine, no statistical difference was found.
Conclusion
Musculoskeletal manifestation is the second most common presenting symptom in a cohort of Egyptian FMF patients after abdominal pain. Arthralgia is the most frequent musculoskeletal manifestation while monoarthritis of the knee or ankle joint is the most common pattern of arthritis in FMF patients. Vertigo, paresthesia, and seizures are the most frequent neurological manifestations. Musculoskeletal manifestations, neurological manifestations, serum amyloid level, and dose of colchicine are not related to the type of the genetic mutation in this cohort.

Abstract
PURPOSE OF REVIEW The main purpose of this review is to present newly reported cutaneous manifestations of systemic vasculitis, updates in investigations to verify systemic involvement in cases with cutaneous vasculitis and new therapeutic guidelines. The spectrum of COVID-19-related vasculitis is also covered. RECENT FINDINGS Only a few reports highlighted new cutaneous presentations or associations with some systemic vasculitic entities. For example, the association of inflammatory disorders with Takayasu arteritis, the importance of considering Kawasaki disease in febrile children with erythema nodosum, the development of necrotic ulcers on fingers and toes in Behçet's disease and the possible presence of polyarteritis nodosa-like pathological features in vulvar ulcers of Behçet's disease. New attempts to classify cutaneous manifestations of giant cell arteritis (GCA) and antineutrophil cytoplasmic antibody-associated vasculitis (AAV) and the diagnostic investigations for cutaneous vasculitis cases to verify systemic involvement are discussed. Treatment of systemic vasculitis with cutaneous vasculitis should be tailored according to disease status. A plethora of reports in the past 2 years focused on the broad spectrum of COVID-19 vasculitic manifestations. SUMMARY Although newly reported cutaneous manifestations of systemic vasculitis are relatively uncommon, the plethora of reports in the past 2 years on COVID-19 vasculitis necessitates the expansion of the classification of vasculitis associated with probable cause to include severe acute respiratory syndrome coronavirus-2 (SARS-Cov-2) vasculitis.
