Background: An anti-cytomegalovirus (CMV) immunoglobulin G (IgG) antibody is produced after primary CMV infection and generally persists after the primary infection. However, it is not well-known about the relationship between anti-CMV IgG titer and outcomes in kidney transplant recipients. We, therefore, aimed to explore the role of anti-CMV IgG titer on the risks of CMV disease development, allograft rejection, renal function decline, and mortality. Methods: In a hospital-based study, we identified 179 CMV-seropositive kidney transplant recipients between January 2013 and December 2017. These patients were divided into low and high anti-CMV IgG titer groups, respectively. The cutoff level of anti-CMV IgG titer was determined by receiver operating characteristic curve analysis. The outcomes evaluated included CMV disease, decrease of =15% in estimated glomerular filtration rate (eGFR), biopsy-proven allograft rejection, and all-cause mortality. Results: The high anti-CMV IgG titer group (=846.2 AU/mL) exhibited a higher risk of CMV disease (adjusted hazard ratio [aHR], 3.77; 95% CI, 1.47-9.68; p = 0.006), eGFR decline =15% (aHR, 2.00; 95% CI, 1.19-3.35; p = 0.009), and renal allograft rejection (aHR, 2.95; 95% CI, 1.11-7.87; p = 0.030) than the low titer group (<846.2 AU/mL). Conclusion: In kidney transplant recipients, a high anti-CMV IgG titer was associated with higher risks for developing CMV disease, undergoing allograft rejection, and eGFR decline.

Dialysis patients are more vulnerable and susceptible to the severe coronavirus disease 2019 (COVID-19) infection due to multiple comorbidities. Since Taiwan has the highest incidence and prevalence of treated end-stage kidney disease world-wide, it is crucial to act in advance to prevent a potential disaster. In the face of the COVID-19 pandemic, we implement proactive infection control measures to prevent it from spreading without sacrificing the dialysis care quality. In this article, we focused on hemodialysis vascular access (HVA) care in particular. As a life-line of hemodialysis (HD) patients, HVA care has a profound impact on the patient’s quality of dialysis and life. Specifically, in our facility, the working and office areas of the HD units are separated to reduce cross-infection. All elective procedures for HVA are postponed, and operating rooms equipped with a negative-pressure anteroom are used for the suspected or confirmed COVID-19 patients. Herein, we share how we modified our HVA care policy not only to prevent our patients from COVID-19 infection but also to maintain the quality of HVA care. [ABSTRACT FROM AUTHOR]

A novel infectious disease, coronavirus disease-2019 (COVID-19), spread globally since December 2019. Without effective treatment and vaccination, the strategies to restrain this disease are only keeping social distance, maintaining personal hygiene, quarantine, and isolation. However, thrice-a-week treatment is inevitable for all hemodialysis patients. In addition to the high risk of cluster infection and compromised immunity in patients with end-stage renal disease (ESRD), an atypical disease presentation could also make the medial system neglect these patients during CVOID-19 pandemic. To avoid COVID-19 transmission among patients on dialysis, the major societies of nephrology around the world have provided their guidelines for screening, dialysis facilities adjustment, and health education, respectively. In this review, we summarized the main contents and differences of these guidelines and addressed the prompt management for patients with ESRD to reduce the risk of infection during COVID-19 pandemic.
