          Abstract

          Resumen Objetivo: describir un caso de trasplante hepático en un paciente con resultado positivo en la prueba del coronavirus del síndrome respiratorio agudo grave de tipo 2 (SARS-CoV-2) con éxito en el postrasplante temprano, pero que desarrolló complicaciones asociadas a la inmunosupresión y trombosis portal sin una trombofilia identificada en un centro de alta complejidad de un país latinoamericano. Descripción del caso: paciente de 48 años con diagnóstico de cirrosis hepática secundaria a esteatohepatitis no alcohólica (NASH) complicada por varios episodios de ascitis portal hipertensiva y encefalopatía hepática, ingresada para trasplante hepático ortóptico. En los exámenes iniciales tuvo una prueba positiva para SARS-CoV-2 y era asintomático respiratorio. El trasplante se realizó con éxito luego de la autorización del comité de infección. Después del primer mes posoperatorio presentó diarrea, ascitis y daño renal agudo. Los niveles de tacrolimus en el reingreso fueron superiores a 10 ng/mL y hubo una mejoría clínica significativa con la suspensión del fármaco. Finalmente, el paciente requirió retrasplante por trombosis de la vena porta y de las venas suprahepáticas, aunque no se identificó la etiología. Conclusión: se describe uno de los primeros informes de trasplante de hígado en un paciente con recuperación reciente de COVID-19 y pruebas persistentemente positivas. En el postrasplante temprano hubo una buena respuesta; sin embargo, luego del primer mes presentó complicaciones relacionadas con la inmunosupresión. Este caso también plantea la posible asociación entre el SARS-CoV-2 y el desarrollo de trombosis en la circulación portal hepática.

          Abstract Objective: To describe a case of liver transplantation in a patient with a positive result in the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) test with success in the early post-transplantation, but who developed complications associated with immunosuppression and portal vein thrombosis without thrombophilia identified at a tertiary referral center in a Latin American country. Case: A 48-year-old patient diagnosed with liver cirrhosis secondary to non-alcoholic steatohepatitis (NASH) complicated by several episodes of portal hypertension ascites and hepatic encephalopathy was admitted for orthoptic liver transplantation. On initial examinations, he had a positive test for SARS-CoV-2 and was asymptomatic in the respiratory tract. The transplant was carried out successfully after the authorization of the infection committee. After the first postoperative month, he presented with diarrhea, ascites, and acute kidney injury. Tacrolimus levels at readmission were more significant than 10 ng/mL, and there was a significant clinical improvement with drug discontinuation. Finally, the patient required re-transplantation due to thrombosis of the portal vein and suprahepatic veins, although the etiology was not identified. Conclusion: One of the first reports of liver transplantation in a patient with recent recovery from COVID-19 and persistently positive tests is described. In the early post-transplant, there was a good response; however, after the first month, he had complications related to immunosuppression. This case also posits the possible association between SARS-CoV-2 and the development of thrombosis in the hepatic portal circulation.

          Virological assessment of hospitalized patients with COVID-2019

          Coronavirus disease 2019 (COVID-19) is an acute infection of the respiratory tract that emerged in late 20191,2. Initial outbreaks in China involved 13.8% of cases with severe courses, and 6.1% of cases with critical courses3. This severe presentation may result from the virus using a virus receptor that is expressed predominantly in the lung2,4; the same receptor tropism is thought to have determined the pathogenicity-but also aided in the control-of severe acute respiratory syndrome (SARS) in 20035. However, there are reports of cases of COVID-19 in which the patient shows mild upper respiratory tract symptoms, which suggests the potential for pre- or oligosymptomatic transmission6-8. There is an urgent need for information on virus replication, immunity and infectivity in specific sites of the body. Here we report a detailed virological analysis of nine cases of COVID-19 that provides proof of active virus replication in tissues of the upper respiratory tract. Pharyngeal virus shedding was very high during the first week of symptoms, with a peak at 7.11 × 108 RNA copies per throat swab on day 4. Infectious virus was readily isolated from samples derived from the throat or lung, but not from stool samples-in spite of high concentrations of virus RNA. Blood and urine samples never yielded virus. Active replication in the throat was confirmed by the presence of viral replicative RNA intermediates in the throat samples. We consistently detected sequence-distinct virus populations in throat and lung samples from one patient, proving independent replication. The shedding of viral RNA from sputum outlasted the end of symptoms. Seroconversion occurred after 7 days in 50% of patients (and by day 14 in all patients), but was not followed by a rapid decline in viral load. COVID-19 can present as a mild illness of the upper respiratory tract. The confirmation of active virus replication in the upper respiratory tract has implications for the containment of COVID-19.

            Incidence of thrombotic complications in critically ill ICU patients with COVID-19

            Introduction COVID-19 may predispose to both venous and arterial thromboembolism due to excessive inflammation, hypoxia, immobilisation and diffuse intravascular coagulation. Reports on the incidence of thrombotic complications are however not available. Methods We evaluated the incidence of the composite outcome of symptomatic acute pulmonary embolism (PE), deep-vein thrombosis, ischemic stroke, myocardial infarction or systemic arterial embolism in all COVID-19 patients admitted to the ICU of 2 Dutch university hospitals and 1 Dutch teaching hospital. Results We studied 184 ICU patients with proven COVID-19 pneumonia of whom 23 died (13%), 22 were discharged alive (12%) and 139 (76%) were still on the ICU on April 5th 2020. All patients received at least standard doses thromboprophylaxis. The cumulative incidence of the composite outcome was 31% (95%CI 20-41), of which CTPA and/or ultrasonography confirmed VTE in 27% (95%CI 17-37%) and arterial thrombotic events in 3.7% (95%CI 0-8.2%). PE was the most frequent thrombotic complication (n = 25, 81%). Age (adjusted hazard ratio (aHR) 1.05/per year, 95%CI 1.004-1.01) and coagulopathy, defined as spontaneous prolongation of the prothrombin time > 3 s or activated partial thromboplastin time > 5 s (aHR 4.1, 95%CI 1.9-9.1), were independent predictors of thrombotic complications. Conclusion The 31% incidence of thrombotic complications in ICU patients with COVID-19 infections is remarkably high. Our findings reinforce the recommendation to strictly apply pharmacological thrombosis prophylaxis in all COVID-19 patients admitted to the ICU, and are strongly suggestive of increasing the prophylaxis towards high-prophylactic doses, even in the absence of randomized evidence.

              Review of the Clinical Characteristics of Coronavirus Disease 2019 (COVID-19)

              In late December 2019, a cluster of cases with 2019 Novel Coronavirus pneumonia (SARS-CoV-2) in Wuhan, China, aroused worldwide concern. Previous studies have reported epidemiological and clinical characteristics of coronavirus disease 2019 (COVID-19). The purpose of this brief review is to summarize those published studies as of late February 2020 on the clinical features, symptoms, complications, and treatments of COVID-19 and help provide guidance for frontline medical staff in the clinical management of this outbreak.
