Diagnostic and therapeutic approach to infectious diseases in solid organ transplant recipients

Jean-François Timsit et al. Intensive Care Med. 2019 May.

Abstract

Purpose: Prognosis of solid organ transplant (SOT) recipients has improved, mainly because of better prevention of rejection by immunosuppressive therapies. However, SOT recipients are highly susceptible to conventional and opportunistic infections, which represent a major cause of morbidity, graft dysfunction and mortality.

Methods: Narrative review.

Results: We cover the current epidemiology and main aspects of infections in SOT recipients including risk factors such as postoperative risks and specific risks for different transplant recipients, key points on anti-infective prophylaxis as well as diagnostic and therapeutic approaches. We provide an up-to-date guide for management of the main syndromes that can be encountered in SOT recipients including acute respiratory failure, sepsis or septic shock, and central nervous system infections as well as bacterial infections with multidrug-resistant strains, invasive fungal diseases, viral infections and less common pathogens that may impact this patient population.

Conclusion: We provide state-of the art review of available knowledge of critically ill SOT patients with infections.

Baseline and acquired determinants of infections in SOT recipients. The recipient’s prior health condition accounts for the risk of infections throughout the post-transplantation period. Early-onset infections are related to acquired defense alterations including breakthrough of natural barriers and immune suppression. Late-onset infections are mostly related to the intensity of the immunosuppressive regimen

Risk factors for early postoperative infections in SOT recipients. Risk factors that predispose to early postoperative infections in recipients of organ transplantation can be categorized as being present before transplant (recipient or donor) and those secondary to intraoperative or post-transplantation factors

Adaptation of the immunosuppressive drugs at the initial phase of sepsis: practical issues. *Immunologic risk assessment: deceased donor, number of human leukocyte antigen (HLA) mismatches, donor-specific antibodies (DSA), organ-specific differences (heart-lung > kidney > liver). Withdrawal of IS drugs should be discussed in close collaboration with transplant physicians
