Article Synopsis
  • The study aimed to enhance the Lund-Malmö GFR equation using rescaled cystatin C (r-LMR) and validate it against measured GFR in a large cohort of children and adults.
  • Validation results showed that r-LMR performed with 86.2% accuracy in adults, outpacing the CAPA equation, indicating r-LMR is a reliable method for estimating GFR.
  • The findings suggest that adapting the Lund-Malmö equation for rescaled cystatin C yields similar results to those based on rescaled creatinine, hinting at a reduced future need for specific GFR estimating equations.

The Role of Pharmacometrics in Advancing the Therapies for Autoimmune Diseases.

Pharmaceutics

December 2024

Department of Pharmacokinetics and Physical Pharmacy, Faculty of Pharmacy, Jagiellonian University Medical College, 9 Medyczna Street, 30-688 Krakow, Poland.

Autoimmune diseases (AIDs) are a group of disorders in which the immune system attacks the body's own tissues, leading to chronic inflammation and organ damage. These diseases are difficult to treat due to variability in drug PK among individuals, patient responses to treatment, and the side effects of long-term immunosuppressive therapies. In recent years, pharmacometrics has emerged as a critical tool in drug discovery and development (DDD) and precision medicine.

Latin Americans have a rich genetic make-up that translates into heterogeneous fractions of the autosomal genome in runs of homozygosity (F) and heterogeneous types and proportions of indigenous American ancestry. While autozygosity has been linked to several human diseases, very little is known about the relationship between inbreeding, genetic ancestry, and cancer risk in Latin Americans. Chile has one of the highest incidences of gallbladder cancer (GBC) in the world, and we investigated the association between inbreeding, GBC, gallstone disease (GSD), and body mass index (BMI) in 4029 genetically admixed Chileans.
