Few reports on infections in thoracic transplantation have been published so far. We present a case of COVID-19 in a 55-year old female lung transplant recipient infected 5 months posttransplant, who additionally was co-infected with a Norovirus. Respiratory and gastrointestinal symptoms were observed without need of therapeutic escalation except for antibiotic therapy. We observed a moderate disease evolution likely due to triple immunosuppression. Keywords: Lung Transplantation; COVID-19; SARS-CoV-2; Coronavirus; norovirus 1. Introduction In late 2019, a novel coronavirus, caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) emerged from Wuhan, China [1]. This virus leads to the coronavirus disease 2019 (COVID-19), currently causing a pandemic with worldwide severe economic and healthcare consequences [2]. Among the most dominant clinical characteristics are fever, cough and fatigue, whereas gastrointestinal symptoms are rather uncommon. Critical disease conditions may be caused by severe and sustained systemic inflammatory responses (hyperinflammation or “cytokine storm”) and a cytopathic effect, leading to acute respiratory distress syndrome (ARDS), septic shock, metabolic acidosis that is hard to correct, coagulation dysfunction and multiple organ failure. The exact viral host factors that influence the pathogenesis are still being investigated. The SARS-CoV-2 infection binds to human host cell receptors, using human angiotensin-converting enzyme 2 (hACE2), although there are more factors influencing susceptibility to infection and disease progression. Elderly people (>65 years of age) with underlying diseases such as hypertension, chronic obstructive pulmonary disease (COPD), diabetes and cardiovascular disease seem more susceptible to an infection and prone to serious outcomes of this viral disease [3]. Since the spread of SARS-CoV-2 around the world, there have only been a few case reports describing COVID-19 in patients after solid organ transplantation (SOT). We present a case of COVID-19 in a lung transplant (LTX) recipient presenting with fever and gastrointestinal symptoms in our emergency department.
