Prevalence of Uncontrolled Hypertension in Patients With Fabry Disease

Background: Fabry disease is a rare X-linked disease arising from deficiency of α-galactosidase A. It results in early death related to renal, cardiac, and cerebrovascular disease, which are also important outcomes in patients with elevated blood pressure (BP). The prevalence of uncontrolled hypertension, as well as the effect of enzyme replacement therapy on BP, in patients with Fabry disease is unknown. Methods: We examined uncontrolled hypertension (systolic BP [SBP] ≥130 mm Hg or diastolic BP [DBP] ≥80 mm Hg) among 391 patients with Fabry disease who were participating in the Fabry Outcome Survey (FOS). Results: Uncontrolled hypertension was present in 57% of men and 47% of women. In patients with chronic kidney disease (CKD) stage 1 (n100), median SBP was 120 mm Hg and median DBP was 74 mm Hg. In patients with CKD stage 2 (n172), median SBP was 125 mm Hg and median DBP was 75 mm Hg. In patients with CKD stage 3 (n63), median SBP was 130 mm Hg and median DBP was 75 mm Hg. There was a significant decrease in both SBP and DBP during a 2-year course of enzyme replacement therapy. Conclusions: This study revealed a high prevalence of uncontrolled hypertension among patients with Fabry disease. Thus there is a need to improve BP control and renoprotection in patients with Fabry diseas

Anemia is a new complication in Fabry disease: Data from the Fabry Outcome Survey

Anemia is a new complication in Fabry disease: Data from the Fabry Outcome Survey.BackgroundThe prevalence and causes of anemia among patients with Fabry disease are unknown.MethodsIn a cross-sectional study we examined hemoglobin concentrations of patients with Fabry disease using a large international database, the Fabry Outcome Survey (FOS), and analyzed the association of renal function, heart failure, gastrointestinal symptoms, and inflammation, with anemia (hemoglobin <12 g/dL in females and <13 g/dL in males).ResultsAnemia was present in 34% of 345 patients with Fabry disease. Median hemoglobin in 158 females was 12.9 g/dL and the median hemoglobin of 187 male patients was 13.2 g/dL. The prevalence of anemia among females was 20%, and among males 47%. Among patients with normal renal function [estimated glomerular filtration rate (GFR) >90 mL/min/1.73 m2] and anemia, heart failure [New York Heart Association (NYHA) class II to IV] and/or elevated C-reactive protein (CRP) levels were documented in 82% of patients. Up to 67% of patients with decreased estimated GFR presented with anemia. There was also a trend for lower hemoglobin levels among patients with signs of inflammation (defined by an elevated CRP level). We observed no association of the presence of gastrointestinal symptoms with anemia. Analyses in 53 patients receiving enzyme replacement therapy for up to 2 years, suggest no effect on anemia.ConclusionThe results of this study point to a high prevalence of anemia among patients with Fabry disease that is in most instances related to impaired renal function, heart failure, and inflammation. This finding may be of clinical relevance, because anemia is a major risk factor for patients with kidney disease, heart failure, or stroke, which are important manifestations of Fabry disease
