Low Penetrance Sarcomere Variants Contribute to Additive Risk in Hypertrophic Cardiomyopathy.

Circulation

December 2024

Department of Internal Medicine, Division of Cardiovascular Medicine, University of Michigan, Ann Arbor. (E.D.S., Y.-C.T., B.E., A.B., O.M., S.S., A.S.H.).

Article Synopsis
  • - Hypertrophic cardiomyopathy (HCM) was traditionally seen as caused by rare, high-risk single-gene changes, but new research indicates common low-risk variants (LowSVs) also play a significant role in the disease.
  • - In a study of over 6000 patients, 12 LowSVs were discovered, which are relatively common in the general population and more prevalent in HCM patients, suggesting they may influence disease severity and risk.
  • - While LowSVs alone are linked to a later onset of HCM and fewer complications, their presence alongside more severe genetic variants increases health risks significantly.

Department of Medicine, Division of Gastroenterology and Hepatology, Center for Esophageal Diseases and Swallowing, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina, USA.

Article Synopsis
  • The study investigates how previous esophageal dilation affects the effectiveness of swallowed corticosteroids in patients with eosinophilic esophagitis (EoE), particularly focusing on the responses to treatment.
  • A post hoc analysis of a phase 3 study on budesonide oral suspension revealed that while histological responses were similar among patients regardless of dilation history, those with a history of dilation had lower dysphagia symptom response rates.
  • The findings suggest that a history of esophageal dilation might complicate the relationship between histological results and dysphagia symptom or endoscopic efficacy outcomes in EoE treatment.

Transplanted islet functional β-cell mass is measured by the β-cell secretory capacity derived from the acute insulin response to glucose-potentiated arginine (AIRpot), however, data are limited beyond one-year post-transplant for individuals with type 1 diabetes. We evaluated changes in β-cell secretory capacity in a single-center longitudinal analysis and examined relationships with measures of islet cell hormone metabolism and clinical measures of graft function (mixed-meal tolerance test [MMTT] C-peptide, BETA-2 score, and continuous glucose monitoring [CGM]). Eleven individuals received purified human pancreatic islets over one or two intra-portal infusions to achieve insulin-independence and were followed over a median (IQR) 6 (5-7) years.
