UNASSIGNED: Primary Sjögren\'s syndrome (PSS) is a systemic autoimmune disease that mainly affects exocrine glands. Little is known about PSS associated cervical and intracranial cerebral large-vessel vasculitis outside of individual case reports.
UNASSIGNED: We present 5 cases of ischemic stroke or transient ischemic stroke (TIA) caused by PSS associated cervical and intracranial large-vessel vasculitis. Literature review was performed to summarize and identify the demographic, clinical features, treatment, and prognosis of this condition.
UNASSIGNED: The review resulted in 8 included articles with 8 patients, plus our 5 new patients, leading to a total of 13 subjects included in the analysis. The median age was 43 (range, 17-69) years old, among which 69.2 % (9/13) were female, and 92.3 % (12/13) came from Asia. Among them, 84.6 % (11/13) presented with cerebral infarction and 70.0 % (7/10) with watershed infarction. Middle cerebral artery (MCA) (6/13, 46.2 %) and internal carotid artery (ICA) (6/13, 46.2 %) were the most frequently involved arteries. Remarkable vessel wall concentric thickening and enhancement was observed in 57.1 % (4/7) patients and intravascular thrombi was identified in 28.6 % (2/7) patients. Glucocorticoid combined with non-glucocorticoid immunosuppressants (8/12, 66.7 %) were the most often chosen medication therapy and 4 patients received surgical intervention.
UNASSIGNED: Asian females are the most vulnerable population to ischemic stroke or TIA due to PSS associated cervical and intracranial large-vessel vasculitis. Cerebral infarctions were characterized by recurrence and watershed pattern. Magnetic resonance vessel wall imaging (MR-VWI) helps to identify the inflammatory pathology of large vessel lesion in PSS.

OBJECTIVE: We aimed to determine the prevalence of cardiovascular involvement in our Blau syndrome (BS) cohort and provide detailed analysis of their cardiovascular manifestations and outcome. We also tried to find out the risk factors for developing cardiovascular involvement.
METHODS: Clinical manifestations, laboratory findings, and treatments were reviewed. Clinical features were compared between children with cardiovascular involvement and those without angiocardiopathy.
RESULTS: A total of 38 BS children were eligible for final analysis. Among them, 13 (34.2%) developed Takayasu-like vasculitis and/or cardiopathy. Compared with those without angiocardiopathy, recurrent fever was more frequent in BS patients with cardiovascular involvement (p < 0.001). What is more, tumor necrosis factor alpha antagonists (anti-TNF) were more urgently needed in children with cardiovascular involvement (p = 0.015). BS patients with cardiovascular involvement include 4 with Takayasu-like vasculitis and 9 with cardiopathy. The onset of cardiovascular manifestations ranged from 0.75 to 18.5 years of age, with most cases occurring before school period. Symptoms were elusive and lacked specificity, such as dizziness, short of breath, and edema. Some patients were even identified because of the unexpected hypertension during follow-up. Cardiopathy and vasculitis occurred in patients with different genotypes. Imaging changes were discovered before the presentation of the typical triad in 3/4 patients with Takayasu-like vasculitis. Three children developed left ventricular dysfunction with decreased left ventricular ejection fraction. Combination of glucocorticoids and methotrexate with anti-TNF agents is a common treatment option for these BS patients. In the cohort, BS-related cardiovascular involvement was controlled well, with cardiac structural and functional abnormalities completely recovered and slower progression of vasculitis lesions.
CONCLUSIONS: Cardiovascular manifestations is not rare in BS patients. Because of its insidious onset, a systematic and comprehensive assessment of cardiovascular involvement should be performed in newly diagnosed patients with BS. Aggressive initiation of anti-TNF agents may be beneficial to improve the prognosis. Key Points • About 34.2% patients with Blau syndrome developed Takayasu-like vasculitis and/or cardiopathy. • Compared with those without angiocardiopathy, recurrent fever and application of anti-TNF agents were more frequent in BS patients with cardiovascular involvement (p < 0.001, p = 0.015) • Regular assessment of cardiovascular involvement is extremely necessary because of its insidious onset.

Takayasu arteritis is a rare disease. Coronary involvement may appear in patients with Takayasu arteritis. With delayed diagnosis and the difficulty of treatment, Takayasu arteritis patients complicated with coronary abnormalities usually have poor prognosis. We present a rare case of acute left heart failure caused by total occlusion of the left main coronary artery due to Takayasu arteritis. A 30-year-old Chinese woman presented at our hospital with recurrent chest tightness accompanied by dyspnoea. A series of modern imaging methods were used for diagnosis and evaluation of Takayasu arteritis, including invasive angiography, CT angiography, and vascular ultrasound. The patient received drugs therapy including glucocorticoids, immunosuppressants, and cardiovascular drugs, without a reperfusion therapy. Cardiac events, inflammatory marks, and cardiac function were observed during 2-year follow-up period. In this paper, we briefly disscuss the diagnosis and treatment for young women with cardiac complication caused by Takayasu arteritis.

BACKGROUND: Musculoskeletal involvement in primary large vessel vasculitis (LVV), including giant cell arteritis and Takayasu\'s arteritis (TAK), tends to be subacute. With the progression of arterial disease, patients may develop polyarthralgia and myalgias, mainly involving muscle stiffness, limb/jaw claudication, cold/swelling extremities, etc. Acute development of rhabdomyolysis in addition to aortic aneurysm is uncommon in LVV. Herein, we report a rare case of LVV with the first presentation of acute rhabdomyolysis.
METHODS: A 70-year-old Asian woman suffering from long-term low back pain was hospitalized due to limb claudication, dark urine and an elevated creatine kinase (CK) level. After treatment with fluid resuscitation and antibiotics, the patient remained febrile. Her workup showed persistent elevated levels of inflammatory markers, and imaging studies revealed an aortic aneurysm. A decreasing CK was evidently combined with elevated inflammatory markers and negativity for anti-neutrophilic cytoplasmic antibodies. LVV was suspected and confirmed by magnetic resonance angiography and positron emission tomography with 18F-fluorodeoxyglucose/computed tomography. With a favourable response to immunosuppressive treatment, her symptoms resolved, and clinical remission was achieved one month later. However, after failing to follow the tapering schedule, the patient was readministered 25 mg/d prednisolone due to disease relapse. Follow-up examinations showed decreased inflammatory markers and substantial improvement in artery lesions after 6 mo of treatment. At the twelve-month follow-up, she was clinically stable and maintained on corticosteroid therapy.
CONCLUSIONS: An exceptional presentation of LVV with acute rhabdomyolysis is described in this case, which exhibited a good response to immunosuppressive therapy, suggesting consideration for a differential diagnosis when evaluating febrile patients with myalgia and elevated CK. Timely use of high-dose steroids until a diagnosis is established may yield a favourable outcome.

Since the publication of the European League Against Rheumatism (EULAR) recommendations for the management of large vessel vasculitis (LVV) in 2009, several relevant randomised clinical trials and cohort analyses have been published, which have the potential to change clinical care and therefore supporting the need to update the original recommendations.
Using EULAR standardised operating procedures for EULAR-endorsed recommendations, the EULAR task force undertook a systematic literature review and sought opinion from 20 experts from 13 countries. We modified existing recommendations and created new recommendations.
Three overarching principles and 10 recommendations were formulated. We recommend that a suspected diagnosis of LVV should be confirmed by imaging or histology. High dose glucocorticoid therapy (40-60 mg/day prednisone-equivalent) should be initiated immediately for induction of remission in active giant cell arteritis (GCA) or Takayasu arteritis (TAK). We recommend adjunctive therapy in selected patients with GCA (refractory or relapsing disease, presence of an increased risk for glucocorticoid-related adverse events or complications) using tocilizumab. Methotrexate may be used as an alternative. Non-biological glucocorticoid-sparing agents should be given in combination with glucocorticoids in all patients with TAK and biological agents may be used in refractory or relapsing patients. We no longer recommend the routine use of antiplatelet or anticoagulant therapy for treatment of LVV unless it is indicated for other reasons.
We have updated the recommendations for the management of LVV to facilitate the translation of current scientific evidence and expert opinion into better management and improved outcome of patients in clinical practice.
