Investigation of Pediatric Hypertension: Use of a Tailored Protocol

Using a comprehensive protocol, the efficacy of simple clinical data, including history, physical examination, and urinalysis, In the discrimination of essential or secondary hypertension was investigated by a review of 103 patients, aged 2 weeks to 18 years, consecutively referred for investigation. Essential hypertension (55/103 mm Hg) was the most common diagnosis, even in infancy, whereas various renal disorders formed the next most common diagnostic category (21/103 mm Hg). Family history and the presence of “fixed” vs “labile” hypertension were of no value in detecting secondary hypertension. Urinalysis was useful in detecting inflammatory renal lesions but not structural disorders of the kidney. This study emphasizes the need for thorough investigation, including renal imaging, of asymptomatic hypertensive children and suggests a useful protocol to achieve this end.
