Endocrine causes of hypertension in children.
Hypertension in children is not a common problem. When it is found, however, a pathologic cause can often be identified. The endocrine causes of hypertension in children are generally rare. We have reviewed the diverse and rare endocrine causes of hypertension in the pediatric population. Table 3 lists features of these conditions that assist in their diagnosis. In all patients with hypertension, a thorough history and physical examination may point to the diagnosis of endocrine or other causes of secondary hypertension. For a more detailed approach to these diagnoses, other reviews may be helpful. A phased laboratory evaluation similar to that suggested by Ogborn and Crocker facilitates in the evaluation of secondary hypertension. The critical screening tests from an endocrine point of view are plasma sodium, potassium, calcium, renin activity, and thyroid function tests, including T4, T3, and thyroid stimulating hormone. Measurement of a 24-hour urine collection for aldosterone, metanephrine, and catecholamines may be warranted if the previously mentioned studies are unrevealing. More specific studies also may be suggested by these preliminary evaluations and the history and physical examination. Further investigations should be done with the additional guidance of a pediatric endocrinologist.
