RESUMEN
Hypertension occurs in some patients with primary nephritic syndrome it may be mediated by changes in vasopressin activities or intravascular volume.Is to find out how many patients with idiopathic nephritic syndrome hare hypertension. The study included 50 children [29 males and 21 females] with age ranger between 1-13 years. Sixteen patients [32%] were with initial attack of nephritic syndrome, while thirty four patients [68%] presented with relapse.Nine [18%] patients had hypertension, eight [16%] patients were relapse cases, and one [2%] patient was with initial attack. Hypertension was found in four [8%] patients with steroid resistant neurotic syndrome, three [6%] patients with steroid sensitive nephritic syndrome in relapse state and two [4%] patients with steroid dependent nephritic syndrome. Abnormal renal function was found in four patients [8%], two [4%] with hypertension and two [4%] without hypertension.It is concluded the necessity of the follow up and periodical measurement of blood pressure of nephritic patients to allow early recognition and management of hypertension.The necessity of the follow up and periodical measurement of blood pressure of nephroticpatients to allow early recognition and management of hypertension
