Diffused coronary involvement in Takayasu arteritis with concomitant malignancy

Infantile Takayasu: clinical features and long-term outcome

OBJECTIVES

Takayasu arteritis (TAK) is a large-vessel vasculitis rarely reported in children and infants. Most articles on paediatric TAK have not focused on infants. We present the largest case series of infantile TAK, aiming to identify its demographic and clinical characteristics and compare them with existing data on older children.

METHODS

We conducted an international multicentre retrospective cohort study. Epidemiological and clinical data were collected from patients' charts from six rheumatology centres. All patients met both the EULAR/PReS 2008 criteria and the 1990 ACR/EULAR criteria and were diagnosed with TAK at age <5 years.

RESULTS

Twelve patients were included (50% female). Median age of symptom onset was 11 months, with a diagnostic delay of 4 months. The most common symptoms at presentation were hypertension, blood pressure differences between limbs, and fever. The most commonly involved arteries were the abdominal aorta and renal artery. Medications included steroids, conventional and biologic DMARDs, and other immunosuppressive therapies. Half of the patients received biologic agents, of which infliximab had the highest complete remission rate (40%). Other medications resulting in complete remission were CYC (40%) and MTX (38%). Invasive procedures were required for 58% of patients. The most common complications were cardiac (50%), stroke (42%), and serious infections (33%). No patients died.

CONCLUSION

This study presents the largest series of infantile TAK. Compared with other reported series on older children, infants with TAK have more severe disease and were more likely to receive biologic agents, develop complications, and require invasive interventions.

Spectrum of Large- and Medium-Vessel Vasculitis in Adults: Neoplastic, Infectious, Drug-Induced, Autoinflammatory, and Primary Immunodeficiency Diseases

Purpose of Review

To provide a comprehensive review of drugs and neoplastic, infectious, autoinflammatory, and immunodeficiency diseases causing medium- to large-vessel vasculitis in adults with emphasis on information essential for the initial diagnostic process.

Recent Findings

Entities with medium- to large-vessel vasculitis as clinical manifestations have been described recently (e.g., adenosine deaminase-2 deficiency, VEXAS-Syndrome), and vasculitis in established autoinflammatory or immunodeficiency diseases is increasingly being identified.

Summary

In the diagnostic process of medium- to large-vessel vasculitis in adults, a large variety of rare diseases should be included in the differential diagnosis, especially if diagnosis is made without histologic confirmation and in younger patients. Although these disorders should be considered, they will undoubtedly remain rare in daily practice.
