Project description:AbstractCoronavirus disease 2019 (COVID-19) is an ongoing pandemic. The occurrence of acute liver injury (ALI) has been reported in liver transplant (LT) recipients; however, the findings on children remain controversial. This is the first extensive, worldwide report on the impact of COVID-19 on pediatric LT recipients. Our online survey reported 110 pediatric LT recipients with severe acute respiratory syndrome coronavirus 2 infection. Of these, 37 were symptomatic and 20 out of them (54%) had complicated COVID-19, which included ALI and acute liver graft rejection. No mortality was reported. Pediatric LT recipients who had undergone transplantation less than 6 months before contracting COVID-19 had a greater number of hospital admissions and a higher ALI frequency (P = 0.013 and P = 0.033, respectively) than those who had undergone transplantation more than 6 months prior. Our study found that COVID-19 cases among pediatric LT recipients demonstrated a high complication rate. We propose that these patients must be followed up strictly.

Project description:BackgroundSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is transmissible through lung transplantation, and outcomes among infected organ recipients may be severe. Transmission risk to extrapulmonary organ recipients and recent (within 30 days of transplantation) SARS-CoV-2-infected recipient outcomes are unclear.MethodsDuring March 2020-March 2021, potential SARS-CoV-2 transmissions through solid organ transplantation were investigated. Assessments included SARS-CoV-2 testing, medical record review, determination of likely transmission route, and recent recipient outcomes.ResultsDuring March 2020-March 2021, approximately 42 740 organs were transplanted in the United States. Forty donors, who donated 140 organs to 125 recipients, were investigated. Nine (23%) donors and 25 (20%) recipients were SARS-CoV-2 positive by nucleic acid amplification test (NAAT). Most (22/25 [88%]) SARS-CoV-2-infected recipients had healthcare or community exposures. Nine SARS-CoV-2-infected donors donated 21 organs to 19 recipients. Of these, 3 lung recipients acquired SARS-CoV-2 infections from donors with negative SARS-CoV-2 testing of pretransplant upper respiratory tract specimens but from whom posttransplant lower respiratory tract (LRT) specimens were SARS-CoV-2 positive. Sixteen recipients of extrapulmonary organs from SARS-CoV-2-infected donors had no evidence of posttransplant COVID-19. All-cause mortality within 45 days after transplantation was 6-fold higher among SARS-CoV-2-infected recipients (9/25 [36%]) than those without (6/100 [6%]).ConclusionsTransplant-transmission of SARS-CoV-2 is uncommon. Pretransplant NAAT of lung donor LRT specimens may prevent transmission of SARS-CoV-2 through transplantation. Extrapulmonary organs from SARS-CoV-2-infected donors may be safely usable, although further study is needed. Reducing recent recipient exposures to SARS-CoV-2 should remain a focus of prevention.

Project description:BackgroundCOVID-19 continues to inflict significant morbidity and mortality, particularly on patients with preexisting health conditions. The clinical course, outcomes, and significance of immunosuppression regimen in heart transplant recipients with COVID-19 remains unclear.MethodsWe included the first 99 heart transplant recipients at participating centers with COVID-19 and followed patients until resolution. We collected baseline information, symptoms, laboratory studies, vital signs, and outcomes for included patients. The association of immunosuppression regimens at baseline with severe disease were compared using logistic regression, adjusting for age and time since transplant.ResultsThe median age was 60 years, 25% were female, and 44% were white. The median time post-transplant to infection was 5.6 years. Overall, 15% died, 64% required hospital admission, and 7% remained asymptomatic. During the course of illness, only 57% of patients had a fever, and gastrointestinal symptoms were common. Tachypnea, oxygen requirement, elevated creatinine and inflammatory markers were predictive of severe course. Age ≥ 60 was associated with higher risk of death and the use of the combination of calcineurin inhibitor, antimetabolite, and prednisone was associated with more severe disease compared to the combination of calcineurin inhibitor and antimetabolite alone (adjusted OR = 7.3, 95% CI 1.8-36.2). Among hospitalized patients, 30% were treated for secondary infection, acute kidney injury was common and 17% required new renal replacement therapy.ConclusionsWe present the largest study to date of heart transplant patients with COVID-19 showing common atypical presentations and a high case fatality rate of 24% among hospitalized patients and 16% among symptomatic patients.

Project description:Background and aimsCoronavirus disease 2019 (COVID-19) is associated with liver injury, but the prevalence and patterns of liver injury in liver transplantation (LT) recipients with COVID-19 are open for study.Approach and resultsWe conducted a multicenter study in the United States of 112 adult LT recipients with COVID-19. Median age was 61 years (interquartile range, 20), 54.5% (n = 61) were male, and 39.3% (n = 44) Hispanic. Mortality rate was 22.3% (n = 25); 72.3% (n = 81) were hospitalized and 26.8% (n = 30) admitted to the intensive care unit (ICU). Analysis of peak values of alanine aminotransferase (ALT) during COVID-19 showed moderate liver injury (ALT 2-5× upper limit of normal [ULN]) in 22.2% (n = 18) and severe liver injury (ALT > 5× ULN) in 12.3% (n = 10). Compared to age- and sex-matched nontransplant patients with chronic liver disease and COVID-19 (n = 375), incidence of acute liver injury was lower in LT recipients (47.5% vs. 34.6%; P = 0.037). Variables associated with liver injury in LT recipients were younger age (P = 0.009; odds ratio [OR], 2.06; 95% confidence interval [CI], 1.20-3.54), Hispanic ethnicity (P = 0.011; OR, 6.01; 95% CI, 1.51-23.9), metabolic syndrome (P = 0.016; OR, 5.87; 95% CI, 1.38-24.99), vasopressor use (P = 0.018; OR, 7.34; 95% CI, 1.39-38.52), and antibiotic use (P = 0.046; OR, 6.93; 95% CI, 1.04-46.26). Reduction in immunosuppression (49.4%) was not associated with liver injury (P = 0.156) or mortality (P = 0.084). Liver injury during COVID-19 was significantly associated with mortality (P = 0.007; OR, 6.91; 95% CI, 1.68-28.48) and ICU admission (P = 0.007; OR, 7.93; 95% CI, 1.75-35.69) in LT recipients.ConclusionsLiver injury is associated with higher mortality and ICU admission in LT recipients with COVID-19. Hence, monitoring liver enzymes closely can help in early identification of patients at risk for adverse outcomes. Reduction of immunosuppression during COVID-19 did not increase risk for mortality or graft failure.

Project description:BackgroundSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can infect any human host, but kidney transplant recipients (KTR) are considered more susceptible on the basis of previous experience with other viral infections. We evaluated rates of hospital complications between SARS-CoV-2-positive KTR and comparator groups.MethodsWe extracted data from the electronic health record on patients who were hospitalized with SARS-CoV-2, testing at six hospitals from March 4 through September 9, 2020. We compared outcomes between SARS-CoV-2-positive KTR and controls: SARS-CoV-2-positive non-KTR, SARS-CoV-2-negative KTR, and SARS-CoV-2-negative non-KTR.ResultsOf 31,540 inpatients, 3213 tested positive for SARS-CoV-2. There were 32 SARS-CoV-2-positive and 224 SARS-CoV-2-negative KTR. SARS-CoV-2-positive KTR had higher ferritin levels (1412; interquartile range, 748-1749 versus 553; interquartile range, 256-1035; P<0.01) compared with SARS-CoV-2-positive non-KTR. SARS-CoV-2-positive KTR had higher rates of ventilation (34% versus 14%, P<0.01; versus 9%, P<0.01; versus 5%, P<0.01), vasopressor use (41% versus 16%, P<0.01; versus 17%, P<0.01; versus 12%, P<0.01), and AKI (47% versus 15%, P<0.01; versus 23%, P<0.01; versus 10%, P<0.01) compared with SARS-CoV-2-positive non-KTR, SARS-CoV-2-negative KTR, and SARS-CoV-2-negative non-KTR, respectively. SARS-CoV-2-positive KTR continued to have increased odds of ventilation, vasopressor use, and AKI compared with SARS-CoV-2-positive non-KTR independent of Elixhauser score, Black race, and baseline eGFR. Mortality was not significantly different between SARS-CoV-2-positive KTR and non-KTR, but there was a notable trend toward higher mortality in SARS-CoV-2-positive KTR (25% versus 16%, P=0.15, respectively).ConclusionsHospitalized SARS-CoV-2-positive KTR had a high rate of mortality and hospital complications, such as requiring ventilation, vasopressor use, and AKI. Additionally, they had higher odds of hospital complications compared with SARS-CoV-2-positive non-KTR after adjusting for Elixhauser score, Black race, and baseline eGFR. Future studies with larger sample size of KTR are needed to validate our findings.PodcastThis article contains a podcast at https://dts.podtrac.com/redirect.mp3/www.asn-online.org/media/podcast/K360/2021_03_25_KID0005652020.mp3.

Project description:BackgroundLiver dysfunction was common in coronavirus disease 2019 (COVID-19), but its association with clinical features and poor prognosis has not been fully delineated. Our study aimed to determine the role of liver dysfunction in COVID-19 and understand the predictors for worse outcomes in patients with liver injury.MethodsWe conducted this multicenter, retrospective study in five designated hospitals for COVID-19 management. Laboratory-confirmed COVID-19 patients were enrolled and classified into the normal live function group and liver dysfunction group according to liver enzymes, bilirubin, and albumin on admission, respectively. Data of baseline, clinical manifestations, and outcomes were collected and compared in the paired groups.ResultsOf the 649 included COVID-19 patients, 200 (30.8%), 69 (10.6%), and 267 (41.1%) patients had elevated liver enzymes, increased bilirubin, and low-level albumin, respectively. Fever, cough, and dyspnea were the most common symptoms and showed an increased proportion in the liver dysfunction group. Compared with patients in the normal liver function group, patients with liver dysfunction manifested decreased lymphocytes, higher level of leukocytes, neutrophils, inflammatory indicators, and cytokines, as well as more severe impairment in kidney function and myocardium. They were more likely to show bilateral involvement and more pulmonary lobes involved according to chest images. With increased proportion of patients who developed severe/critical conditions and needed mechanical ventilation and systemic glucocorticoid therapy, patients with liver dysfunction on admission showed significantly higher in-hospital mortality. Moreover, cardiac troponin I ≥1.5 ng/mL was identified as an independent mortality predictor in the elevated liver enzymes group.ConclusionPatients with liver dysfunction on admission had worse clinical manifestation, and resulted in higher rate of severe/critical type, receiving mechanical ventilation and in-hospital mortality.

Project description:Approximately 2% of heathy persons are infected with human pegivirus (HPgV). HPgV is transmitted via vertical, sexual, and blood-borne routes. Recently, the association of HPgV infection with the risk of lymphoma was reported. We examined the prevalence of chronic HPgV infection in liver transplantation (LT) recipients and hepatectomy patients and the influence of HPgV infection after LT on clinical and perioperative factors. We enrolled 313 LT recipients and 187 hepatectomy patients who received care at the Kyusyu University Hospital between May 1997 and September 2017. Total RNA was extracted from peripheral blood samples of patients/recipients collected postoperatively. HPgV RNA was measured using real-time polymerase chain reaction (RT-PCR). Of the 313 recipients and 187 patients enrolled in this study, 44 recipients (14.1%) and two patients (1.1%) had HPgV viremia. There was no significant association between HPgV infection and LT outcomes. Interestingly, one recipient was infected with HPgV during the peritransplant period, which was likely transmitted via blood transfusion as HPgV RNA was detected from the blood bag transfused to the recipient during LT. Additionally, HPgV infection induced the upregulation of interferon stimulated gene (ISG) expression in peripheral blood mononuclear cells (PBMCs). LT recipients had higher HPgV viremia compared to hepatectomy patients. Although HPgV infection was not associated with LT-related outcomes, it induced ISG expression in recipients.

Project description:Background: The probable impact of a maintenance immunosuppressant (IS) on liver transplant (LT) recipients with coronavirus disease 2019 (COVID-19) remains unexplored. Our specific aim was to approximate the prognosis of LT recipients with COVID-19 on the standard maintenance IS. Method: We searched separate databases for the qualified studies in between December 2019 and June 25, 2021. Ultimately, a meta-analysis was carried out using a fixed-effect or random-effect model based on the heterogeneity. Results: In a total of eight studies and 509 LT recipients with COVID-19, the pooled rates of severity and mortality during all the combined immunosuppressive therapies were 22.4 and 19.5%, respectively. Our study sufficiently showed that an immunosuppressive therapy in LT recipients with COVID-19 was significantly associated with a non-severe COVID-19 [odds ratio (OR): 11.49, 95% CI: 4.17-31.65; p < 0.001] and the survival of the patients (OR: 17.64, 95% CI: 12.85-24.22; p < 0.001). Moreover, mammalian target of rapamycin inhibitor (mTORi) typically had the lowest rate of severity and mortality compared to other ISs such as calcineurin inhibitors (CNIs), steroids, and antimetabolites, i.e., severity (13.5 vs. 21.1, 24.7, and 26.3%) and mortality (8.3 vs. 15, 17.2, and 12.1%), respectively. Contrary to the general opinions, our meta-analysis showed comorbidities such as diabetes, hypertension, cardiopulmonary disorders, chronic kidney disease (CKD), age >60, the duration of LT to the diagnosis of COVID-19, primary disease for LT, and obesity were not significantly associated with the severity and mortality in LT recipients with COVID-19 under an immunosuppressive therapy. However, our pooled analysis found that LT recipients with COVID-19 and without comorbidities have a less severe disease and low mortality rate compared to those with both COVID-19 and comorbidities. Conclusions: In conclusion, LT recipients with COVID-19 undergoing immunosuppressive therapies are not significantly associated with the severity and mortality. Therefore, taking the risk of organ rejection into a key consideration, a complete withdrawal of the IS may not be wise. However, mycophenolate mofetil (MMF) might be discontinued or replaced from an immunosuppressive regimen with the CNIs- or mTORis-based immunosuppressive therapy in some selected LT recipients with COVID-19, depending upon the severity of the disease.

Project description:Coronavirus disease 2019 (COVID-19) can become complicated by secondary invasive fungal infections (IFIs), stemming primarily from severe lung damage and immunologic deficits associated with the virus or immunomodulatory therapy. Other risk factors include poorly controlled diabetes, structural lung disease and/or other comorbidities, and fungal colonization. Opportunistic IFI following severe respiratory viral illness has been increasingly recognized, most notably with severe influenza. There have been many reports of fungal infections associated with COVID-19, initially predominated by pulmonary aspergillosis, but with recent emergence of mucormycosis, candidiasis, and endemic mycoses. These infections can be challenging to diagnose and are associated with poor outcomes. The reported incidence of IFI has varied, often related to heterogeneity in patient populations, surveillance protocols, and definitions used for classification of fungal infections. Herein, we review IFI complicating COVID-19 and address knowledge gaps related to epidemiology, diagnosis, and management of COVID-19-associated fungal infections.

Project description:BackgroundWe evaluated trends and outcomes of liver transplantation (LT) recipients with/without HIV infection.MethodsLT recipients between 2008 and 2015 from the United Network for Organ Sharing and Organ Procurement and Transplantation Network and European Liver Transplant Registry were included. Trends and characteristics related to survival among LT recipients with HIV infection were determined.ResultsAmong 73 206 LT patients, 658 (0.9%) were HIV-infected. The proportion of LT HIV-infected did not change over time (P-trend = 0.16). Hepatitis C virus (HCV) as indication for LT decreased significantly for HIV-infected and HIV-uninfected patients (P-trends = 0.008 and <0.001). Three-year cumulative graft survival in LT recipients with and without HIV infection was 64.4% and 77.3%, respectively (P < 0.001), with improvements over time for both, but with HIV-infected patients having greater improvements (P-trends = 0.02 and 0.03). Adjusted risk of graft loss was 41% higher in HIV-infected versus HIV-uninfected (adjusted hazard ratio [aHR], 1.41; P < 0.001). Among HIV-infected, model of end-stage liver disease (aHR, 1.04; P < 0.001), body mass index <21 kg/m (aHR, 1.61; P = 0.006), and HCV (aHR, 1.83; P < 0.001) were associated with graft loss, whereas more recent period of LT 2012-2015 (aHR, 0.58; P = 0.001) and donor with anoxic cause of death (aHR, 0.51; P = 0.007) were associated with lower risk of graft loss.ConclusionsPatients with HIV infection account for only 1% of LTs in United States and Europe, with fewer LT for HCV disease over time. A static rate of LT among HIV-infected patients may reflect improvements in cirrhosis management and/or persistent barriers to LT. Graft and patient survival among HIV-infected LT recipients have shown improvement over time.
