Abstract:
Objective:To explore the epidemiological characteristics, risk factors, preventions and treatments of recent human parvovirus B19 (HPV-B19) infections in recipients of renal transplantation (RT).Methods:From May 2020 to June 2021, retrospective review was conducted for epidemiological characteristics, treatment protocols, preventions and outcomes of HPV-B19 infected recipients after RT.Risk factors were analyzed using uninfected recipients after RT in the same period as controls.And 78 recipients who were not infected after RT with similar operation time were used as a control group for risk factor analysis.The infection rates of the four liver transplant recipients infected with HPV-B19 during the same period were calculated and compared with those of the kidney transplant recipients.Chi-square test and Fisher's exact test were used for statistical analysis.Results:During the observation period, HPV-B19 infection occurred in 39/368 recipients after RT with an overall infection rate of 10.60%(39/368). In terms of clinical symptoms, all 39 recipients presented with pure red cell aplasia (PRCA). In terms of season of infection, HPV-B19 infections occurred predominantly in autumn and winter [74.3% (29/39) of infections in autumn and winter, including 48.7% (19/39) in autumn]. Comparing the infection rates of different transplant recipients, 4 out of 123 liver transplant recipients were infected with HPV-B19 during the same period.The rate of infection was lower in liver transplant recipients than in RT counterparts (3.25% vs.10.60%, χ2=6.225, P=0.013). Analysis of OR values showed that transfusion of blood products was a risk factor for recent postoperative infection ( χ2=4.806, P=0.028, OR=2.418, 95% CI=1.088-5.373). Conclusions:HPV-B19 infection in renal transplant patients is mainly manifested as PRCA and is more likely than in liver transplant patients.Autumn and winter may be susceptible seasons for HPV-B19 and protection should be increased to prevent infection.Transfusion of blood products is a risk factor for recent HPV-B19 infection after RT, therefore donors should be routinely examined and it is imperative to test the safety of blood products in patients after RT.Thus HPV-B19 infection is well-controlled so that further spread may be prevented to avoid an epidemic outbreak.
