AI Article Synopsis

  • Bruton's tyrosine kinase inhibitors (BTKis), like acalabrutinib, are the recommended treatment for chronic lymphocytic leukemia (CLL) but can increase the risk of severe infections.
  • A 68-year-old male patient developed multiple types of infections, including bacterial, fungal, and viral, while being treated with acalabrutinib.
  • This case highlights a potential pattern of increased infection risk associated with BTKis, particularly suggesting that such risks may be a common side effect of the entire medication class.

Article Abstract

Bruton's tyrosine kinase inhibitors (BTKis) are the preferred treatment for chronic lymphocytic leukemia (CLL). Despite their therapeutic benefits, these targeted agents have been associated with an increased risk of invasive infections. We describe a 68-year-old male who developed multiple bacterial, fungal and viral infections while on treatment with acalabrutinib. To our knowledge, this is the first reported case of concomitant CNS infections with and along with cytomegalovirus (CMV) and herpes simplex virus type 1 (HSV-1) pneumonia while on acalabrutinib. This case adds to the scarce literature of fungal and bacterial infections associated with acalabrutinib, raising the suspicion that infection risk is a medication class effect for BTKis.

Relationship between systemic immune-inflammation index and depression among individuals with and without cardiovascular disease.

J Cardiothorac Surg

January 2025

Department of Hematology, Jinhua People's Hospital, No.267, Danxi East Road, Jinhua, 321000, Zhejiang, P.R. China.

Objective: Depression is a common comorbidity in cardiovascular disease (CVD), and both conditions are associated with chronic inflammation. The systemic immune-inflammation index (SII) has emerged as a promising marker of systemic inflammation, but its role in association with depressive symptoms, particularly in the context of CVD, remains unclear. This study aims to investigate the association of SII with depressive symptoms in individuals with and without CVD using cross-sectional data from NHANES (2005-2016).

Metabolic reprogramming, malignant transformation and metastasis: lessons from chronic lymphocytic leukaemia and prostate cancer.

Cancer Lett

January 2025

Clinical and Health Sciences, University of South Australia, Adelaide, Australia; Department of Histopathology, Trinity College Dublin, St. James's Hospital, Dublin, Ireland. Electronic address:

Metabolic reprogramming is a hallmark of cancer, crucial for malignant transformation and metastasis. Chronic lymphocytic leukaemia (CLL) and prostate cancer exhibit similar metabolic adaptations, particularly in glucose and lipid metabolism. Understanding this metabolic plasticity is crucial for identifying mechanisms contributing to metastasis.

This case report presents a complex medical scenario involving early 60s female patient with a history of chronic lymphocytic leukaemia (CLL) complicated by Evans syndrome, characterised by autoimmune haemolytic anaemia and immune thrombocytopenia. The patient had received various treatments, including steroids, rituximab, cyclosporine and acalabrutinib. The patient's neurological symptoms began around 3 years prior to presentation, with shaking of her right leg, followed by shaking of both hands, particularly the left hand.
