Background: A three-dose regimen is the current standard for COVID-19 vaccination, but systematic data on immunogenicity and safety in chronic kidney disease patients remains limited.

Objectives: We conducted a meta-analysis on the immunogenicity and safety of three-dose COVID-19 vaccination in patients on renal replacement therapy (RRT).

Methods: Systematic literature search in four electronic databases yielded twenty eligible studies (2,117 patients, 94% of whom received mRNA vaccines) for meta-analysis.

Cardiovascular disease, infection, malignancy, and thromboembolism are major causes of morbidity and mortality in kidney transplant recipients (KTR). Prospectively identifying monogenic conditions associated with post-transplant complications may enable personalized management. Therefore, we developed a transplant morbidity panel (355 genes) associated with major post-transplant complications including cardiometabolic disorders, immunodeficiency, malignancy, and thrombophilia.

Introduction: It remains unclear how the presence of renal involvement will affect the cardiovascular (CV) risk factors and complications in patients with SLE.

Methods: We conducted a systematic review and meta-analysis using PubMed, EMBASE, MEDLINE and Scopus to identify studies published between 1947 and 2022 that evaluate the CV risk factors and complications in patients with SLE with or without lupus nephritis (LN).

Results: 58 studies were evaluated, with 22 two-arm studies (n=8675) included in two-arm meta-analysis and 45 studies (n=385 315) included in proportional meta-analysis.

Background: Asia is the global epicenter of the coronavirus disease 2019 (COVID-19) pandemic; however, COVID-19-related mortality in Asia remains lower than in other parts of the world. It is uncertain whether the mortality of COVID-19-infected kidney transplant recipients (KTXs) from Asia follows the lower mortality trends of the younger Asian population.

Methods: Specific transplant centers from countries in the Asian Society of Transplantation were invited to participate in a study to examine the epidemiology, clinical features, natural history, and outcomes of COVID-19 infections in KTXs.

Background: Systematic data on the efficacy and safety of COVID-19 vaccine in patients on renal replacement therapy (RRT) remains limited. We conducted a meta-analysis on the efficacy and safety of COVID-19 vaccine in patients on RRT.

Methods: Eligible studies were identified by systematic literature search in four electronic databases.

Clinical outcomes of COVID-19 vary considerably between patients. Little was known about the clinical course and optimal management of immunosuppressed patients infected with SARS-CoV-2. We report a kidney transplant recipient with COVID-19 who presented with pneumonitis and acute kidney injury (AKI).

Hepatitis B virus (HBV), influenza, pneumococcus and herpes zoster are important infections which could result in significant morbidity and mortality in patients with chronic kidney disease (CKD). While seroconversion rates after vaccination are often lower in CKD patients compared with healthy adults due to impaired innate and adaptive immunity, vaccinations for HBV, influenza, pneumococcus and herpes zoster are generally effective in reducing the transmission and/or severity of these infections. Practical issues that have an impact on the efficacy of vaccination in the CKD population include the timing, dose, schedule of vaccination, the route of administration, and adjuncts applied at time of vaccination.
