Lung09 NovDOI: Lung transplantation is a lifesaving intervention for patients with advanced lung disease. Due to a combination of immunosuppression, continuous exposure of the lungs to the environment, and complications at the anastomotic sites, lung transplant recipients are at high risk for infectious complications.

Introduction

The aim of this review is to summarize recent developments in the field of infectious diseases as it pertains to lung transplant recipients. Over the past 20 years, lung transplantation has emerged as a lifesaving surgery for those with chronic lung disease, leading to significantly improved outcomes. According to the International Society for Heart and Lung Transplantation registry, there have been 69, adult lung transplants performed worldwide as of June 30th,with a median survival of 7. While life expectancy has increased over time, The Anti Pseudomonal Vaccine Potential Of Pa0721 remain a common cause of morbidity and mortality in transplant recipients, and are the leading cause of death between one month and one year post-transplant [ 1 ]. The high rate of infection seen post-transplant is multifactorial. Continuous exposure of the lungs to the environment, the potency of immunosuppression required to prevent rejection, complications at the anastomotic sites, and impaired mucociliary clearance all play an important role [ 2 ].

While direct microbial damage contributes to overall morbidity and mortality in lung transplant patients, the complex relationship between infection Homeschooling Persuasive chronic graft rejection is also a key factor.

Infections, particularly due to cytomegalovirus CMV and other respiratory viruses, are known to contribute to the development of BOS. Furthermore, concomitant increases in immunosuppression needed to control rejection source in an increased risk of subsequent infection, which can make lung transplant recipients challenging to manage. The success of lung transplantation depends on the careful balance of immunosuppression to prevent rejection while at the same time minimizing infectious risks. In order to maximize contribution to the extensive literature on this subject, this review focuses primarily on recent developments in the field. Infections in lung transplant recipients can be acquired de novo post-transplant but can also be donor-derived or caused by reactivation of latent infection in the recipient.

Therefore, a comprehensive pre-transplant screening of both recipients and donors is required. Special note should be made of all previously diagnosed infections.

Bleeding: uncommon; usually start treatment.

This is particularly important for patients with cystic fibrosis or other suppurative lung diseases since Mrs Dalloway patients often have complicated infectious histories, including both active infections and colonization with multi-drug resistant organisms MDROs. Such patients should receive double lung transplantation to prevent infection of the allograft, and the presence of MDROs may change perioperative antimicrobial management. In addition to infectious history, a detailed social history including but not limited to country of origin, travel, occupational history, recreational activities and contact with pets and domesticated animals should be obtained from the recipient The Anti Pseudomonal Vaccine Potential Of Pa0721 assess for potential latent infections.

If a latent infection is identified, treatment is often recommended pre-transplant. The donor should be tested for bacterial, viral, fungal, mycobacterial and parasitic infections and both sputum and serologic tests should be confirmed to evaluate for these organisms. Though donor screening strategies can identify many transmissible infections, some infections, such as rabies and West Nile virus, may still go undetected and be transmitted to the recipient [ 56 ]. Geographic considerations should Potentisl taken into Poetntial when identifying infectious risks.

Knowledge about specific immunity to certain infections is crucial as it guides the need for post-transplant prophylaxis. Those with the highest risk include recipients who are seronegative and receive organs from seropositive donors. All donors and recipients should also be screened for severe acute respiratory syndrome coronavirus 2 SARS-CoV-2 infection by nasopharyngeal polymerase chain reaction PCR regardless of symptoms immediately prior to donation and transplant, respectively. While data and guidelines regarding transplantation in the setting of the coronavirus disease COVID pandemic are emerging, all attempts should be made to ensure there is no evidence of active disease at the time of transplant, and if there is any concern or ambiguity sending PCR from bronchioalveolar lavage BAL of the donor lung should be considered. The recommendations further state that all deceased donor should be tested within 96 hours of organ procurement, and transplant candidates should The Anti Pseudomonal Vaccine Potential Of Pa0721 tested immediately prior to transplantation, as well as 4—6 weeks post-transplant, regardless of donor risk profile [ 7 ].

Transplant recipients are also at an increased risk for cervical cancer due to human papilloma virus HPVand should be screened with an increased frequency, concurrent with guidelines for HIV-infected individuals [ 8 ]. Perioperative antimicrobials are imperative in lung transplant recipients, however, there are no established guidelines or treatment standards for these patients [ 9 ].

At most institutions, recipients are empirically covered for Gram-positive and Gram-negative organisms, most often with an anti-pseudomonal beta lactam as well as an agent with activity against methicillin-resistant Staphylococcus aureus Pseudomonap. Antibiotics should begin immediately prior to surgery and continue for at least 2—5 days, though the optimal duration of therapy is not well established.]
