In the past two decades, there has been a great deal of work aimed to devise diagnostic guidelines, classification criteria, and diagnostic scores for cytokine storm syndromes (CSSs). The most notable effort has been the large-scale multinational study that led to the development of the 2016 classification criteria for macrophage activation syndrome (MAS) complicating systemic juvenile idiopathic arthritis (JIA). Future studies should scrutinize the validity of the proposed criteria, particularly in systemic JIA patients treated with biologics, in children with subtle or incomplete forms of MAS, and in patients with MAS complicating other rheumatologic disorders.

Article Synopsis
  • The study aims to evaluate the current treatment approaches for macrophage activation syndrome (MAS) globally and identify inconsistencies in clinical practices.
  • A thorough literature review resulted in 57 relevant papers involving 1148 patients with MAS, primarily linked to systemic juvenile idiopathic arthritis (sJIA), systemic lupus erythematosus (SLE), and Kawasaki disease (KD).
  • Findings indicate high-dose glucocorticoids and certain targeted therapies, such as IL-1 and IFNγ inhibitors, are effective, particularly for sJIA-associated MAS, but highlight a need for more standardized research to improve treatment consistency for different conditions.

Article Synopsis
  • The study analyzed the current diagnostic criteria for familial hemophagocytic lymphohistiocytosis (FHL) and aimed to improve them through a case-control approach involving 366 children with genetic FHL or Griscelli syndrome.
  • It compared the existing HLH-2004 criteria's effectiveness with a new optimal model based on 17 variables, finding similar diagnostic thresholds with high accuracy rates (99.1% overall).
  • The researchers concluded that while the HLH-2004 criteria are valid, additional cellular and genetic assays are beneficial for confirming diagnoses, particularly in differentiating FHL from severe infections or systemic-onset juvenile idiopathic arthritis.

Article Synopsis
  • Federated learning (FL) is a technique that allows hospitals to develop predictive models without sharing patient records, but it may affect model performance negatively compared to centralized methods.
  • The study evaluated four strategies for predicting 30-day mortality in patients undergoing transcatheter aortic valve implantation (TAVI), including centralized learning and various federated approaches.
  • The results showed that federated approaches delivered similar predictive performance in terms of the area under the curve (AUC) and calibration, suggesting that FL can be a practical option for developing clinical prediction models.
