Uncontrolled hypertension in Fabry disease


Sunderplassmann, G (2004). Uncontrolled hypertension in Fabry disease. American Journal of Hypertension, 17(5):S206.

Abstract

Fabry disease is a x-linked lysosomal storage disease leading to early death related to renal, cardiac, and cerebrovascular disease. Therefore, proper diagnosis and therapy of elevated blood pressure may improve morbidity and mortality of these patients. However, the prevalence of uncontrolled hypertension in Fabry disease is unknown. We examined blood pressure of patients with Fabry disease using a large international database, the Fabry Outcome Survey (FOS). We defined uncontrolled hypertension as a systolic blood pressure (SBP) ≥130, and/or a diastolic blood pressure (DBP) ≥ 80 mmHg (threshold for blood pressure control in renal disease, JNC7). We used the short MDRD-GFR formula for assessment of renal function, and we classified chronic kidney disease according to K/DOQI. Among 459 patients with Fabry disease, 306 had blood pressure readings entered in the database. Mean SBP was 124.6 ± 16.9 mmHg and mean DBP was 73.6 ± 11.7 mmHg (mean age: 38.4 ± 15.6 years, 142 females, 164 males). Fourty-three percent of men and and 28% of women showed uncontrolled hypertension. In 291 patients both, blood pressure readings and GFR estimates, were available. In patients with normal GFR (>90 ml/min/1.73m2) mean SBP was 119.5 ± 15.6 mmHg and mean DBP was 69.7 ± 11.1 mmHg (n=120). In patients with mild decreased GFR (60-89 ml/min/1.73m2) mean SBP was 126.7 ± 15.9 mmHg and mean DBP was 75.0 ± 11.0 mmHg (n=110). In patients with moderate decreased GFR (30-59 ml/min/1.73m2) mean SBP was 132.7 ± 20.8 mmHg and mean DBP was 79.0 ± 13.3 mmHg (n=41). In 70 patients blood pressure readings were available before start of enzyme replacemen therapy (ERT) with agalsidase alfa (Replagal, TKT 5S Europe, 0.2 mg/kg bodyweight fortnightly i.v.), in 87 at 12 months and in 76 at 24 months of therapy. At baseline, at 12 and at 24 months of ERT, 39%, 30% and 42%of the patients presented with uncontrolled hypertension, respectively. Our study revealed a high prevalence of uncontrolled hypertension among patients with Fabry disease. Thus, there is need for improvement of blood pressure control in these patients.
