Thrombocytopenia is one of the common complications after liver transplantation,with pathophysiological mechanisms including insufficient platelet production and increased platelet consumption,which severely affects the prognosis of liver transplant recipients.Various factors such as preoperative hepatitis virus infection,intraoperative ischemic injury,and postoperative use of immunosuppressive drugs may lead to thrombocytopenia after liver transplantation.Early detection and effective treatment of thrombocytopenia after liver transplantation are currently hot topics of research.Based on the existing literature,this article reviews the definition,pathophysiological mechanisms,risk factors,treatment,and prevention of thrombocytopenia,and discusses the occurrence and development of thrombocytopenia after liver transplantation and related diagnosis and treatment strategies,aiming to optimize the existing treatment opinions,reduce the risk of thrombocytopenia after transplantation and improve the prognosis of liver transplant recipients.

Objective:To analyze the clinical characteristics of novel coronavirus (COVID-19) infection in liver transplant recipients.Methods:Clinical data of 130 liver transplant recipients with COVID-19 infection followed in Hebei Medical University Third Hospital from November 2022 to January 2023 were retrospectively collected, including 103 males and 27 females, aged (53.6±11.4) years. The severity of COVID-19 infection, its clinical symptoms, and negative conversion time for each recipient were analyzed and compared.Results:For the disease severity, 121 (93.1%) were mild, 5 (3.8%) were moderate, 3 (2.3%) were severe, and 1 (0.8%) was critically severe. The most common symptoms in the 126 patients with mild to moderate COVID-19 infection were successively fever, fatigue, cough and myalgia, with a negative conversion time of (10.1±4.5) (3.0-29.0)d. In those who underwent transplantation less than 12 months ( n=28), those who were taking mycophenolate mofetil ( n=53) and those who were taking methylprednisolone ( n=10), the negative conversion time was (11.6±5.1) d, (11.4±5.4) d, and (13.4±6.4) d, respectively, longer compared to those who underwent transplantation more than 12 months (9.7±4.2 d, n=98), and who were not taking mycophenolate mofetil (9.2±3.4 d, n=73) or methylprednisolone (9.8±4.2 d, n=116, all P<0.05). The negative conversion times were longer in recipients with symptoms (eg. fatigue and cough) than those in asymptomatic recipients (11.0±5.1 d vs. 9.0±3.3 d, t=2.64, P=0.009, and 11.4±5.2 d vs. 9.0±3.4 d, t=2.92, P=0.004). Conclusion:The COVID-19 infection in liver transplant recipients was mainly mild and moderate. The most common symptoms are fever, fatigue, cough and myalgia. The short time (less than 12 months) after liver transplantation, oral mycophenolate mofetil and methylprednisolone, with symptoms (fatigue and cough) could be associated with a prolonged negative conversion time.
