Tocilizumab administration in cytokine release syndrome is associated with hypofibrinogenemia after chimeric antigen receptor T-cell therapy for hematologic malignancies.

Chimeric antigen receptor (CAR) T-cell therapy causes serious side effects including cytokine release syndrome (CRS). CRS-related coagulopathy is associated with hypofibrinogenemia that has up to now been considered the result of disseminated intravascular coagulation (DIC) and liver dysfunction. We investigated the incidence and risk factors for hypofibrinogenemia in 41 consecutive adult patients with hematologic malignancies (median age 69 years, range 38-83 years) receiving CAR T-cell therapy between January 2020 and May 2023 at the University Medical Center Regensburg.

Biomechanical stress in the context of competitive sports training triggers enthesitis.

Objective: To evaluate the influence of mechanical stress on the development of immediate enthesitis.

Methods: The BEAT study is an interventional study that assessed entheses in competitive badminton players before and immediately after a 60-min intensive training session. Power Doppler (PD) signal and Gray scale (GS) changes were assessed in the insertion sites of both Achilles tendon, patellar tendons, and lateral humeral epicondyles and quantified using a validated scoring system.
