Prevention of infections is crucial in solid organ transplant (SOT) candidates and recipients. These patients are exposed to an increased infectious risk due to previous organ insufficiency and to pharmacologic immunosuppression. Besides infectious-related morbidity and mortality, this vulnerable group of patients is also exposed to the risk of acute decompensation and organ rejection or failure in the pre- and post-transplant period, respectively, since antimicrobial treatments are less effective than in the immunocompetent patients...

RATIONALE & OBJECTIVE: Vaccination for influenza is strongly recommended for people with chronic kidney disease (CKD) due to their immunocompromised state. Identifying risk factors for not receiving an influenza vaccine (non-vaccination) could inform strategies for improving vaccine uptake in this high-risk population. STUDY DESIGN: Longitudinal observational study. SETTING & PARTICIPANTS: 3,692 Chronic Renal Insufficiency Cohort Study (CRIC) participants...

Immunocompromised (IC) populations are at increased risk of vaccine-preventable diseases (VPDs). In India, the concern of VPDs in IC populations is particularly acute due to the prevalence of crowded living situations, poor sanitation and variable access to healthcare services. We present a narrative review of IC-related disease and economic burden, risk of VPDs and vaccination guidelines, based on global and India-specific literature (2000-2022). IC conditions considered were cancer, diabetes mellitus, chronic kidney disease, respiratory disorders, disorders treated with immunosuppressive therapy, and human immune deficiency virus (HIV)...

The coronavirus disease 2019 (COVID-19) pandemic revealed that our understanding of infectious complications and strategies to mitigate severe infections in patients with glomerular diseases is limited. Beyond COVID-19, there are several infections that specifically impact care of patients receiving immunosuppressive measures. This review will provide an overview of six different infectious complications frequently encountered in patients with glomerular diseases, and will focus on recent achievements in terms of vaccine developments and understanding of the use of specific antimicrobial prophylaxis...

The use of live attenuated vaccines in patients with immunosuppressive agents is contraindicated in package inserts and guidelines in Japan and other countries. However, patients receiving immunosuppressants have a high risk of infectious disease becoming severe, and the necessity to prevent infectious disease is high. To date, 2,091 vaccinations have been reported in 25 reports of live attenuated vaccines in people receiving immunosuppressants. Twenty-three patients (1.1%) became infected with the virus strain used in the vaccine, which was varicella virus in 21 patients...

Effective vaccination strategies are of crucial importance to protecting patients who are vulnerable to infections, such as patients with chronic kidney disease. This is because the decreased efficiency of the immune system in chronic kidney disease impairs vaccine-induced immunisation. COVID-19 has prompted investigation of the immune response to SARS-CoV-2 vaccines in chronic kidney disease and in kidney transplant recipients in an effort to improve efficacy. The seroconversion rate after two vaccine doses is reduced, especially in kidney transplant recipients...

BACKGROUND: The use of vaccination to prevent infection has a long history, starting in the 1700s with Jenner. New innovations have led to improvements in the safety and efficacy of vaccines, from live attenuated viruses to subunit vaccines, to RNA-based vaccination for SARS-CoV-2. Despite this progress, however, solid organ transplant (SOT) recipients on immunosuppression demonstrate an impaired vaccine response compared with healthy controls. This issue is important given the increased vulnerability to infection in immunocompromised patients, especially in the setting of the Coronavirus Disease 2019 (COVID-19) pandemic...

BACKGROUND: Although case reports have described relapses of glomerular disease after COVID-19 vaccination, evidence of a true association is lacking. In this population-level analysis, we sought to determine relative and absolute risks of glomerular disease relapse after COVID-19 vaccination. METHODS: In this retrospective population-level cohort study, we used a centralized clinical and pathology registry (2000-2020) to identify 1105 adult patients in British Columbia, Canada, with biopsy-proven glomerular disease that was stable on December 14, 2020 (when COVID-19 vaccines first became available)...

INTRODUCTION: Assessing vaccine serologic status presents opportunities to provide live vaccinations to kidney transplant candidates (KTC). This is especially important given the increased risk of infection while taking lifelong immunosuppression following transplant and the inability to routinely provide live vaccines to patients on immunosuppressive medications. In March 2019, the American Society of Transplantation Infectious Disease Community of Practice (AST-IDCOP) released updated guidelines for vaccination of KTC, which emphasize pretransplant viral serology screening and live vaccine administration prior to transplant...

BACKGROUND AND OBJECTIVES: Dialysis patients have a high mortality risk after coronavirus disease 2019 (COVID-19) and an altered immunologic response to vaccines, but vaccine clinical effectiveness remains unknown in this population. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Using Bayesian multivariable spatiotemporal models, we estimated the association between vaccine exposure and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) severe infections (with hospital admission) in dialysis patients from simultaneous incidence in the general population...

Hepatitis B vaccination is recommended in all patients with end-stage kidney disease (ESKD). However, only 50-60% of these patients achieve protective antibody levels if immunized after starting dialysis. Strategies to overcome this low seroconversion rate include a 6-month vaccination schedule starting earlier [chronic kidney disease (CKD) stage 4 and 5] to ensure immunity when patients progress to ESKD. We conducted a quality improvement program to immunize pre-dialysis patients. Patients who were found to have a negative baseline serology with a negative hepatitis B surface antibody level (HBsAb) were offered vaccination on a 6-month schedule (0, 1 and 6 months) with one of two available vaccines within the VA system (Recombivax™ or Engerix™)...

BACKGROUND AND OBJECTIVES: Antibody response after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination is impaired in kidney transplant recipients. Emerging variants, such as B.1.617.2 ( δ ), are of particular concern because of their higher transmissibility and partial immune escape. Little is known about protection against these variants in immunocompromised patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: In this prospective two-center study, antispike 1 IgG and surrogate neutralizing antibodies were measured in 173 kidney transplant recipients and 166 healthy controls with different vaccination schedules...

Since the first case of COVID-19 was identified in the USA in January, 2020, over 46 million people in the country have tested positive for SARS-CoV-2 infection. Several COVID-19 vaccines have received emergency use authorisations from the US Food and Drug Administration, with the Pfizer-BioNTech vaccine receiving full approval on Aug 23, 2021. When paired with masking, physical distancing, and ventilation, COVID-19 vaccines are the best intervention to sustainably control the pandemic. However, surveys have consistently found that a sizeable minority of US residents do not plan to get a COVID-19 vaccine...

The coronavirus disease 2019 (COVID-19) vaccine and its utility in solid organ transplantation need to be timely revised and updated. These guidelines have been formalized by the experts-the apex technical committee members of the National Organ and Tissue Transplant Organization and the heads of transplant societies-for the guidance of transplant communities. We recommend that all personnel involved in organ transplantation should be vaccinated as early as possible and continue COVID-19-appropriate behavior despite a full course of vaccination...

OBJECTIVE: To identify barriers and enablers to COVID-19 vaccination in renal transplant recipients who are undecided about vaccination. METHODS: An online survey was distributed to 876 adult kidney transplant recipients at a tertiary referral service, who had not been vaccinated against COVID-19. The survey assessed willingness to be vaccinated, attitudes toward COVID-19 vaccines and barriers and enablers to proceeding with vaccination. RESULTS: The survey response rate was 54% (473/876)...

Background: Accumulating evidence suggests that solid organ transplant recipients, as opposed to the general population, show strongly impaired responsiveness towards standard SARS-CoV-2 mRNA-based vaccination, demanding alternative strategies for protection of this vulnerable group. Methods: In line with recent recommendations, a third dose of either heterologous ChAdOx1 (AstraZeneca) or homologous BNT162b2 (BioNTech) was administered to 25 kidney transplant recipients (KTR) without humoral response after 2 doses of BNT162b2, followed by analysis of serological responses and vaccine-specific B- and T-cell immunity...
