Article Synopsis
  • Patients with hemophilia B receive factor IX concentrates to prevent bleeding, and new extended half-life (EHL) options allow for less frequent dosing compared to standard treatments.
  • The recombinant FIX-Fc fusion protein (rFIXFc) is highlighted for its rapid distribution, potentially due to its binding to type IV collagen in the body, which may help prevent bleeding even when FIX activity is not measurable in plasma.
  • A physiologically based pharmacokinetic (PBPK) model accurately predicts how rFIXFc behaves in the body, showing significantly higher concentrations of the drug in the extravascular space compared to plasma, indicating its crucial role in achieving effective bleeding control after treatment.

Thyroid-stimulating hormone (TSH) and subsequent free thyroxine (FT4) concentrations outside the reference interval (RI) are used to diagnose thyroid diseases. Most laboratories do not provide age-specific RIs for TSH and FT4 beyond childhood, although TSH concentrations vary with age. Therefore, we aimed to establish TSH and FT4 age-specific RIs throughout life and aimed to determine whether using these RIs would result in reclassification of thyroid disease diagnoses in adults.

Establishing Treatment Effectiveness in Fabry Disease: Observation-Based Recommendations for Improvement.

Int J Mol Sci

September 2024

Department of Endocrinology and Metabolism, Amsterdam Gastroenterology Endocrinology Metabolism, Amsterdam UMC Location University of Amsterdam, 1105 AZ Amsterdam, The Netherlands.

Article Synopsis
  • Fabry disease (FD) results from mutations in a specific gene that lead to a deficiency in the enzyme α-galactosidase A, causing harmful substrate accumulation, with symptoms varying widely between male and female patients.
  • Although FD therapies like enzyme replacement therapy (ERT) and chaperone therapy have been available for around 20 years, there is still limited evidence supporting their long-term effectiveness due to diverse patient populations and inconsistencies in study designs.
  • To improve future research on FD treatments, the review suggests better patient matching, international collaboration, and standardized approaches for evaluating treatment effectiveness, including clear recommendations for study outcomes and duration.

Heart Rhythm

September 2024

Department of Clinical and Experimental Cardiology, Amsterdam UMC Location University of Amsterdam, Heart Center, Amsterdam, The Netherlands; Amsterdam Cardiovascular Sciences, Heart Failure & Arrhythmias, Amsterdam UMC location AMC, Amsterdam, The Netherlands. Electronic address:

Sudden cardiac death (SCD) remains a pressing health issue, affecting hundreds of thousands each year globally. The heterogeneity among people who suffer a SCD, ranging from individuals with severe heart failure to seemingly healthy individuals, poses a significant challenge for effective risk assessment. Conventional risk stratification, which primarily relies on left ventricular ejection fraction, has resulted in only modest efficacy of implantable cardioverter-defibrillators for SCD prevention.
