AbstractIntroductionTakayasu’s arteritis is a rare idiopathic arteritis causing stenosis or aneurysms of the aorta, pulmonary arteries, and their branches. It usually occurs in women, but has been described in children.ObjectiveThe objective of this study was to determine the clinical presentation, demographic profile, vascular involvement, origins, management, and outcome of children diagnosed with Takayasu’s arteritis at a Southern African tertiary care centre between 1993 and 2015.MethodsThis is a retrospective analysis of all children with Takayasu’s arteritis captured on a computerised electronic database during the study period.ResultsA total of 55 children were identified. The female:male ratio was 3.2:1, and the mean age was 9.7±3.04 years. Most originated outside the provincial borders of the study centre. The majority presented with hypertension and heart failure. In all, 37 (67%) patients had a cardiomyopathy with a mean fractional shortening of 15±5%. A positive purified protein derivative test was documented in 73%. Abdominal aorta and renal artery stenosis were the predominant angiographic lesions. A total of 23 patients underwent 30 percutaneous interventions of the aorta, pulmonary, and renal arteries: eight stents, 22 balloon angioplasties, and seven had nephrectomies. All patients received empiric tuberculosis treatment, immunosuppressive therapy, and anti-hypertensive agents as required. Overall, there was a significant reduction in systolic blood pressure and improvement in fractional shortening (p<0.05) with all treatments.ConclusionTakayasu’s arteritis is more common in girls and frequently manifests with hypertension and heart failure. The abdominal aorta and renal arteries are mostly affected. Immunosuppressive, anti-hypertensive, and vascular intervention therapies improve blood pressure control and cardiac function.
