Respiratory Virus Infections

Abstract Background Community acquired respiratory virus infections (RVI) are a major concern in solid organ transplant (SOT) recipients due to severe complications such as lower respiratory tract infection (LRTI), superimposed fungal and bacterial pneumonia, intensive care admission and mortality. Besides influenza and respiratory syncytial virus (RSV), there is paucity of data of RVI in SOT recipients. Table 1: Patients characteristics Table 2: Concomitant infections Methods Retrospective cohort study of a single large transplant center was performed. Data of multiplex qualitative PCR-based respiratory viral panel (RVP) samples collected between January 2017 and December 2019 were included. It is important to mention that our institution generally performs the RSV/influenza rapid detection assay as an initial test; if negative, the multiplex PCR panel is usually done. We did not include results from the RSV/influenza rapid test in this study. Results One hundred transplant patients with a single positive RVP were included (table 1). Transplanted organs include kidney (40%), followed by lung (33%) and liver (9%). Most common presenting symptoms were cough (52%), shortness of breath (28%) and rhinorrhea (26%). Of note fever was seen in only 24%. Most common RVI was Rhinovirus/Enterovirus (RHV/ENT) (59%), followed by non-SARS-CoV-2 Coronavirus (19%) and Parainfluenza (PIV) (14%). None of the patients had neutropenia, however, 52% had lymphocytopenia. Lung transplant patients developed LRTI in 70% of cases compared to non-lung transplant 64% (p=0.412). Multivariate analysis showed patients with PIV 3 were less likely to develop LRTI (p= 0.038). Significant Cytomegalovirus DNAemia (>137 IU/mL) was noted in 9.8% of the recipients. No proven or probable pulmonary fungal infection were noted within 3 months after diagnosis of RVI. Five patients were admitted to the Intensive care unit due to septic shock. Three patients died at 4, 5 and 35 days after diagnosis of RHV/ENT, PIV-3 and RHV/ENT respectively. Conclusion Most of the cases of RVI were due to RHV/ENT. Patients with PIV 3 were less likely to develop LRTI. Lung transplant recipients developed LRTI with similar incidence to non-lung recipients. Our data shows a very low mortality of 3% after RVI in our SOT cohort, which warrants larger studies. Disclosures Michele I. Morris, MD, Viracor Eurofins (Advisor or Review Panel member)

Medical Advances

The first successful organ transplant was a kidney transplant performed between identical twins in 1954. Since that time, major medical advances have been made to help improve survival rates for transplant recipients. In 2008, there were 1,964 solid organ transplants performed for children under age 18 (2007 Organ Procurement and Transplantation Network and the Scientific Registry of Transplant Recipients [OPTN/SRTR] Annual Report 1997–2006). Currently, approximately 1,830 pediatric patients are awaiting some type of solid organ transplant (2007 OPTN/SRTR Annual Report 1997–2006). Organ transplantation in children is relatively recent compared to other treatments for children with chronic illnesses. The focus over the first few decades has been on medical advances and improving survival rates for transplant patients. In the recent years, increasing attention has been given to the developmental, neurocognitive, and psychosocial outcomes prior to transplant and in the short-term period post transplant. Most chronic illnesses and acute traumatic medical events have implications for neurocognitive outcomes. End-stage disease of the liver, kidney, heart, and lung are all believed to affect intellectual, academic, and neurocognitive functions. Gross neurodevelopmental deficits have become less common due to early medical intervention (e.g., improved nutrition, surgical intervention, reduced exposure to aluminum (Warady 2002). Organ transplantation is believed to ameliorate the deleterious long-term developmental and neurocognitive effects, but this topic has received little attention in the literature, and the available results with regard to intellectual, academic, and neurodevelopmental results have been mixed. In a combined sample of solid organ transplant patients, 40% had clinically significant cognitive delays (Brosig et al. 2006). Examining the impact of different underlying disease processes and transplantation of each solid organ separately is critical. Thus, we discuss the neurocognitive outcomes of each organ group separately in this chapter. Neurocognitive outcomes can be assessed in a variety of ways depending upon the age of the child. Among infants and toddlers, neurocognitive functioning is measured by an assessment of motor function, social and environmental interaction, and language development. Assessment of older children may involve the evaluation of intelligence, academic achievement, emotional and behavioral functioning, and adaptive skills.

Introduction Non-valvular cardiac aspergillosis is a rare infection of the pericardium, myocardium or endocardium and is associated with a high mortality. There is a paucity of reports of non-valvular cardiac aspergillosis in critically ill and solid organ transplant (SOT) patients. The majority of cases have been reported in haemato-oncology patients, some of whom have undergone a bone marrow transplant. Objectives We describe four cases affected by non-valvular cardiac aspergillosis in the intensive care setting including a systematic review of this extremely rare infection which is associated with high mortality. Results All four-patients died but presented with varying clinical, radiological and microbiological evidence of the disease. Three patients presented following complications after solid organ transplantation, two in the context of acute liver failure and emergency liver transplant and one several years after a double lung transplant. The last patient presented with necrotising gall stone pancreatitis, multi-organ failure and subsequently a prolonged intensive care unit (ICU) stay. On review of the literature, January 1955 to July 2019, 45 cases were identified, with different risk factors, clinical and radiological manifestations, treatment regimen and outcome. Conclusion Antemortem diagnosis of cardiac aspergillosis is difficult and rare, with no cases reporting positive blood culture results. Galactomannan serology has poor sensitivity in solid organ transplant patients, further reduced by prophylactic antimicrobial treatment, which is common in the ICU setting especially post-transplant patients. Due to the scarcity of cases, treatment is extrapolated from invasive aspergillosis management, with emphasis on early treatment with combination therapy.

AbstractBackgroundManagement of COVID-19 in transplant patients is a big challenge. Data on immunosuppression management, clinical picture, and outcomes are lacking.ObjectivesTo summarize the current literature on COVID-19 in transplant patients especially the data regarding the immunosuppression protocols, clinical presentation, and outcomes.Search strategyA systematic search of MEDLINE, EBSCO, CENTRAL, CINAHL, LitCovid, Web of Science, and Scopus electronic databases. The references of the relevant studies were also searched. The search was last updated on June 3, 2020.Selection CriteriaPrimary reports of solid organ transplant patients who developed COVID-19. An overlap of cases in different reports was checked.Data collection and analysisA descriptive summary of immunosuppression therapy (before and after COVID-19), clinical presentation (symptoms, imaging, laboratory, and disease severity), management (oxygen therapy, antiviral, and antibacterial), major outcomes (Intensive care admission, invasive mechanical ventilation, acute kidney injury), and mortality.Main resultsWe identified 74 studies reporting 823 cases of solid organ transplantation with COVID-19. Among 372 patients, 114 (30.6%) were mild COVID-19, 101 (27.2%) moderate, and 157 (42.2%) severe or critical.Major outcomes included intensive care unit admission, invasive ventilation, and acute kidney injury, which occurred in 121 (14.7%), 97 (11.8%), and 63 (7.7%) of patients, respectively. Mortality was reported in 160 (19.4%) patients. Missing individual data hindered making clinical correlations.ConclusionCOVID-19 in solid organ transplant patients probably has a more disease severity, worse major outcomes (Intensive care admission, invasive ventilation, acute kidney injury), and higher mortality than in non-transplant patients.

Abstract Background Respiratory virus infection (RVI) in pediatric solid organ transplant (SOT) recipients poses a significant risk; however, the epidemiology and effects of an RVI after pediatric SOT in the era of current molecular diagnostic assays are unclear. Methods A retrospective observational cohort of pediatric SOT recipients (January 2010 to June 2013) was assembled from 9 US pediatric transplant centers. Charts were reviewed for RVI events associated with hospitalization within 1 year after the transplant. An RVI diagnosis required respiratory symptoms and detection of a virus (ie, human rhinovirus/enterovirus, human metapneumovirus, influenza virus, parainfluenza virus, coronavirus, and/or respiratory syncytial virus). The incidence of RVI was calculated, and the association of baseline SOT factors with subsequent pulmonary complications and death was assessed. Results Of 1096 pediatric SOT recipients (448 liver, 289 kidney, 251 heart, 66 lung, 42 intestine/multivisceral), 159 (14.5%) developed RVI associated with hospitalization within 12 months after their transplant. RVI occurred at the highest rates in intestine/abdominal multivisceral (38%), thoracic (heart/lung) (18.6%), and liver (15.6%) transplant recipients and a lower rate in kidney (5.5%) transplant recipients. RVI was associated with younger median age at transplant (1.72 vs 7.89 years; P < .001) and among liver or kidney transplant recipients with the receipt of a deceased-donor graft compared to a living donor (P = .01). The all-cause and attributable case-fatality rates within 3 months of RVI onset were 4% and 0%, respectively. Multivariable logistic regression models revealed that age was independently associated with increased risk for a pulmonary complication (odds ratio, 1.24 [95% confidence interval, 1.02–1.51]) and that receipt of an intestine/multivisceral transplant was associated with increased risk of all-cause death (odds ratio, 24.54 [95% confidence interval, 1.69–327.96]). Conclusions In this study, hospital-associated RVI was common in the first year after pediatric SOT and associated with younger age at transplant. All-cause death after RVI was rare, and no definitive attributable death occurred.
