Sepsis is a life-threatening organ dysfunction caused by dysregulated host response to infection. Immunosuppression is an important factor of secondary infection in the late state of sepsis, including multi-drugs resistant bacteria, which ultimately leads to the death of patients. The aim of this article was to help clinical staffs better manage patients with sepsis, improve long-term survival rate of the patients, and reduce their re-hospitalization rate by reviewing the relationship between sepsis-induced immunosuppression and multi-drugs resistant bacteria through three aspects: the mechanism of sepsis-induced immunosuppression, the mechanism of antibiotic resistance and the relationship between sepsis-induced immunosuppression and secondary infections.

Background: Interleukin-6 (IL-6) plays a central role in sepsis-induced cytokine storm involving immune hyperactivation and early neutrophil activation. Programmed death protein-1 (PD-1) is associated with sepsis-induced immunosuppression and lymphocyte apoptosis. However, the effects of simultaneous blockade of IL-6 and PD-1 in a murine sepsis model are not well understood.

Background: Sepsis is commonly associated with acute respiratory distress syndrome (ARDS). Although the exaggerated inflammation may damage intact lung tissues, a percentage of patients with ARDS are reportedly immunocompromised, with worse outcomes. Herein, using a murine sepsis model, time-course immune reprogramming after sepsis was evaluated to explore whether the host is immunocompromised.

Sepsis is a major medical problem which causes millions of deaths worldwide every year. The host immune response in sepsis is characterized by acute inflammation and a simultaneous state of immunosuppression. In the later stage of sepsis, immunosuppression is a crucial factor that increases the susceptibility of septic patients to secondary infection and mortality.

The immune system undergoes profound dysregulation in sepsis, characterized by hyperinflammation in the acute phase followed by long-lasting immunosuppression. T-cell exhaustion has been proposed as one facet of sepsis-related immunosuppression, which is characterized by impaired effector function and continuous expression of PD1. However, the current analysis of T-cell exhaustion in the post-sepsis is inadequate.
