Study of Takayasu's Arteritis in Children: Clinical Profile and Management

AIMS: To study clinical features, pattern of involvement and treatment modalities of Takayasu's arteritis (TA) in children. MATERIAL AND METHODs: Retrospective analysis of hospital records of children admitted over a period of 4.5 years. Results: 17patients in the age group of 5 to 11 years (M: F = 1.1: 1) were diagnosed to have TA on the basis of Ishikawa's criteria. One child was diagnosed post-mortem. The commonest presenting features were hypertension (64.7%), congestive cardiac failure (47%), weak or absent peripheral pulses, cardiomyopathy (41.1% each) and cardiac valvular affection (35.2%). Retinopathy, hypertensive encephalopathy and abdominal bruits were uncommon. None presented in the prepulseless phase. No patient had an active tuberculous lesion, although Mantoux or BCG test was positive in 6 (35.2%). The predominant pattern of angiographic affection was Type II (52.9%). Nephrotic syndrome and portal cavernoma seen in one patient each were incidental associations. Anti-hypertensive drugs, oral steroids and drugs to control congestive heart failure were the mainstays of medical management. Antitubercular therapy was started in six patients. Angioplasty was attempted in 15 cases and proved to be partially beneficial in six. Three patients who failed to respond to medical management had to undergo surgical procedures, either bypass, nephrectomy or both. In-hospital mortality was 11.7%. Conclusions:of TA in this study presented acutely in the pulseless phase, with hypertension and its complications. Type II involvement was the commonest pattern. Anti-hypertensive agents and steroids along with angioplasty were partially successful in controlling symptoms in 35.2%. Surgical procedures were reserved for a minority with poor response to drugs and angioplasty.
