Sepsis is a life-threatening condition. Programmed cell death 1 protein (PD-1), a negative costimulatory molecule, is suggested to be involved in pathogenesis as mortality is associated with high expression and as neutralizing antibodies improve survival in a mouse model. The PD-1 gene harbors an intronic single-nucleotide polymorphism, rs11568821, which is located in a transcription factor-binding site and supposed to affect PD-1 transcription. ⋯ Data provide first associative evidence for PD-1 rs11568821 as a prognostic indicator in patients with sepsis.

Interleukin 27 (IL-27), belonging to the IL-12 family, exerts a critical role in immune regulation of infection, autoimmunity, and tumor. In this study, we aimed to investigate the roles of IL-27 and vascular endothelial growth factor (VEGF) in breast cancer. ⋯ Interleukin 27 may be a new prognostic biomarker of breast cancer and a promising target to limit both angiogenesis and tumor growth.

Sepsis in neonates hospitalized in the neonatal intensive care unit is a global problem and is a significant contributor to morbidity and mortality. Neutrophil surface CD64, the high-affinity Fc receptor, is quantitatively up-regulated during infection and sepsis. ⋯ CD64 expression on neutrophils increases significantly in neonates with sepsis and can be considered a useful diagnostic marker for early diagnosis of neonatal infection as a single determination compared with other inflammatory markers.

The objective of this study was to evaluate the effect of simultaneous bilateral intra-articular injection (IAI) of methylprednisolone acetate (MPA) on the hypothalamic-pituitary-adrenal axis in patients with knee osteoarthritis. ⋯ Secondary adrenal insufficiency was very common following simultaneous bilateral IAI of 80 mg of MPA. Although it was transient, SAI could still be observed nearly 2 months after the IAI, in 10% of the patients.
