• Absence of mortality differences between the 1st and 2nd covid waves in kidney transplant recipients
  SARS-CoV-2 pandemic evolved in two consecutive waves over 2020. Improvements in the management of COVID-19 led to a reduction of mortality rates in hospitalized patients during the second wave. Whether this progress also benefited to kidney transplant recipients (KTR), a population particularly vulnerable to severe COVID-19, remained unclear.
• COVID-19 vaccine effectiveness in patients with non-dialysis dependent chronic kidney diseases; findings from a population based observational study from British Columbia, Canada
  Patients with chronic kidney disease (CKD) are considered to be a high-risk group for contracting SARS-CoV-2 (COVID-19) infection and post-infection complications. Recent research investigating the COVID-19 vaccine effectiveness (VE) in CKD population mostly involve patients receiving renal replacement therapy including kidney dialysis or transplantation. Little is known about the VE in non-dialysis dependent CKD patients.
• Improved immune response to the third COVID-19 mRNA vaccine dose in hemodialysis patients
  A third dose of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccine has been administered in several countries.
• A Randomized Control Trial of Ravulizumab for Treatment of Patients with COVID-19 Infection and Kidney Injury
  Patients affected by severe COVID-19 infection often develop end-organ damage that manifests as acute kidney injury (AKI). It has been reported that greater than 20% of such patients are diagnosed with AKI while the long term impact on future prevalence of chronic kidney disease (CKD) has yet to be rigorously quantitated.
• Increased rates of supplement-associated oxalate nephropathy during COVID-19 pandemic
  Causes of secondary oxalate nephropathy include enteric dysfunction and excessive intake of oxalate or oxalate precursors. During the COVID-19 pandemic, there has been a dramatic rise in sales of supplements and vitamin C, during which time we observed an apparent increase in the proportion of ingestion-associated oxalate nephropathy.
• Incidence of new onset glomerulonephritis after SARS-CoV-2 mRNA vaccination is not increased.
  Numerous cases of glomerulonephritis manifesting shortly after SARS-CoV-2 vaccination have been reported, but causality remains unproven. Here, we studied the association between mRNA-based SARS-CoV-2 vaccination and new-onset glomerulonephritis using a nationwide retrospective cohort and a case-cohort design.
• Clinical Effectiveness and Safety of Remdesivir in Hemodialysis Patients with COVID-19
  Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread globally since December 2019. Remdesivir has been widely used for COVID-19 treatment since it has received an Emergency Use Authorization by the US Food and Drug Administration in May 2020.
• Safety, Efficacy and Relapse of Nirmatrelvir-Ritonavir in Kidney Transplant Recipients Infected with SARS-CoV-2
  Nirmatrelvir-ritonavir (NR) has demonstrated its efficacy to decrease the risk of progression to severe COVID-19 in high-risk patients. However, evidence in infected kidney transplant recipients (KTRs) is lacking. Moreover, NR has significant and potentially harmful interactions with calcineurin inhibitors (CNIs).
• A rapid decline in the anti-receptor binding domain of the SARS-CoV-2 spike protein IgG titer in kidney transplant recipients after tixagevimab-cilgavimab administration
  Immunocompromised patients are at high risk of severe COVID-19 and show an impaired anti-SARS-CoV-2 vaccine response even after four vaccine doses.
• The effectiveness and safety of mRNA (BNT162b2) and inactivated (CoronaVac) COVID-19 vaccines among individuals with chronic kidney diseases
  The ongoing COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has posed a serious threat to individuals with underlying chronic kidney disease (CKD). People with CKD are immunocompromised and therefore result in poorer outcomes including increased risk of hospitalization and mortality after COVID-19.
• Use of remdesivir in kidney transplant recipients with sars-cov-2 omicron infection
  Infection from the Omicron variant of SARS-CoV-2 seems to be less severe in general population in comparison with the previous variants of concern. However, in kidney transplant recipients (KTR) Omicron continues to be a considerable threat, due to immunosuppression status and blunt response to vaccination
• How does diabetes cause susceptibility to COVID in the kidney: new clues provided by organoids
  Early in the pandemic, diabetes was recognized as a risk factor for poor prognosis in patients with COVID-19. Although diabetes does not appear to increase the risk of infection with SARS-CoV-2, individuals with diabetes are more susceptible to severe COVID-19
• How was kidney care reshaped by the COVID-19 pandemic?
  Since the World Health Organization (WHO) announced the emergence of several cases of pneumonia in Wuhan City, Hubei Province, China, a debate on the efficiency of healthcare systems has captured the attention of a broad audience worldwide.
• An ISN-DOPPS survey of the global impact of the Coronavirus 2019 pandemic on peritoneal dialysis services
  Home over center-based dialysis may minimize SARS-CoV2 exposure risks. We explored how the pandemic may have introduced challenges related to peritoneal dialysis (PD) supply availability, routine patient care, and how facility practices changed during this time.
• Covid-19 infection does not alter HLA antibody reactivity
  The requirement for immunosuppression in organ transplant recipients, particularly suppression of the T cell response, has made this population especially vulnerable to prolonged and severe infections during the ongoing SARS-CoV-2 pandemic.
• Covid-19 morbidity decreases with Tixagevimab/cilgavimab preexposure prophylaxis in kidney transplant recipients non/low vaccine responders
  SARS-Cov-2 infection is associated with high mortality in kidney transplant recipients (KTRs). Unfortunately, they display a poor humoral immune response following Covid-19 mRNA vaccination.
• COVID-19 pandemic waves and mortality among patients on kidney replacement therapy
  Using data from the largest European database of KRT patients with COVID-19, that was collected at multiple centers across Europe and has detailed information on key covariates, we compared mortality between the first and second pandemic waves among dialysis patients and kidney transplant recipients with COVID-19.
• A retrospective cohort study measured predicting and validating the impact of the COVID-19 pandemic in individuals with chronic kidney disease.
  Chronic kidney disease (CKD) is associated with increased risk of baseline mortality and severe COVID-19, but analyses across CKD stages, and comorbidities are lacking.
• Immunologic Responses Following COVID-19 Vaccination in Patients with Membranous Nephropathy Receiving Anti-CD38 Felzartamab Therapy: Results from the Phase 1b/2a M-PLACE Study
  Mass vaccination against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has been one of the pivotal public health strategies to curb the coronavirus disease 2019 (COVID-19) outbreak. Currently, there are insufficient data on the immune response to COVID-19 vaccines in patients with autoimmune kidney diseases, especially those receiving immunosuppressive drugs.
• COVID-19 vaccination in patients with membranous nephropathy
  While the benefit of COVID-19 vaccination is evident, many patients and caregivers might question the safety of COVID-19 vaccines in view of case reports that reported relapsing disease after vaccination (1-4). A balanced discussion is difficult, in view of lacking data.
• Efficacy of anti SARS-CoV-2 monoclonal antibodies prophylaxis and vaccination on Omicron COVID-19 in kidney transplant recipients
  Solid organ transplantation (SOT) recipients are at very high risk of developing severe COVID-19. Despite the implementation of a third dose of mRNA vaccine, the efficacy of SARS-CoV-2 vaccination on humoral and cellular immunities is reduced in this population, resulting in increased severe infections and mortality, including in fully vaccinated patients.
• Inferior cellular and humoral immunity against Omicron and Delta VOC compared to SARS-CoV-2 wild-type in hemodialysis patients immunized with four SARS-CoV-2 vaccine doses
  With the dominance of the most recent SARS-CoV-2 variant of concern (VOC) Omicron (B.1.1.529), the question arises, what is the reason for its high contagiousness in COVID-19 vaccinated dialysis patients as compared to the previous SARS-CoV-2 variants Delta and wild-type.
• Humoral response to heterologous SARS-CoV-2 vaccination in kidney transplant patients is heterogeneous and dose-dependent
  Vaccination is the cornerstone in the fight against the ongoing COVID-19 pandemic. Kidney transplant recipients (KTR) had a weak immunological response after 2 doses of either vaccine scheme.
• SARS-CoV-2 infection evolution among nephrologists during the pandemic: clinical features and impact of vaccination
  Exposure of healthcare workers (HCW) to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in high rates of coronavirus-19 disease (COVID-19). Nephrologists have been at the front line as patients on kidney replacement therapy present more severe COVID-19 and need continuous medical assistance
• Early treatment with sotrovimab monoclonal antibody in kidney transplant recipients with Omicron infection
  Since its first detection in November 2021, the SARS-CoV-2 B.1.1.529 (Omicron) variant has rapidly become the dominant variant worldwide. Increased transmissibility and its ability to evade both vaccine and infection induced neutralising antibodies was of significant global concern, and was the impetus for the UK to expedite it’s booster vaccination programme.
• Suboptimal antibody response against SARS-CoV-2 Omicron variant after third dose of mRNA vaccine in kidney transplant recipients
  Coronavirus disease (COVID-19) caused by severe acute respiratory coronavirus 2 (SARS-CoV-2) has resulted in over five million deaths worldwide with the Delta (B.1.617.2) and more recently the Omicron (B.1.1.529) variants accounting for the majority of cases.
• Early treatment with sotrovimab monoclonal antibody in kidney transplant recipients with Omicron infection
  Early data about COVID-19 related to SARS-CoV-2 Omicron variant (B.1.1.529) suggest that it may be less severe than prior variants of concern in the general population.
• Humoral response after a fourth “booster” dose of a Covid-19 vaccine following a 3-dose regimen of mRNA-based vaccination in dialysis patients
  Despite an initial satisfactory increase in SARS-CoV-2 anti-spike antibody (Ab) titer after completing a 3-dose regimen in the first set of vaccination in dialysis patients,1 Ab titer substantially decreases at 6 months in this population
• COVID-19 vaccination response in kidney transplant recipients with and without mycophenolate mofetil: follow-up of a randomized controlled trial
  Antimetabolite therapy is considered a risk factor for poor vaccination response to COVID-19 vaccination.
• Early administration of Anti-SARS-CoV-2 Monoclonal Antibodies prevents severe Covid-19 in Kidney Transplant Patients
  Kidney transplant recipients (KTRs) are prone to develop severe coronavirus disease 2019 (Covid-19) and are less well protected by vaccine than immunocompetent subjects.
• The Longitudinal Evolution of Post-COVID-19 Outcomes Among Hemodialysis Patients in Turkey
  Hemodialysis (HD) patients have increased risk for short-term adverse outcomes of COVID-19. However, complications and survival at the post-COVID-19 period have not been published extensively.
• Concurrent vaccination of kidney transplant recipients and close household cohabitants against COVID-19
  Kidney transplant recipients (KTRs) are highly vulnerable to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and severe coronavirus disease 2019 (COVID-19). The 28-day case mortality in KTRs is 24%, and mounting evidence suggests poor immunogenicity and clinical effectiveness of vaccines in this group.
• Inferior humoral and sustained cellular immunity against wild type and omicron VOC in hemodialysis patients immunized with three SARS-CoV-2 vaccine doses compared to four doses
  Studies analyzing humoral immunity against the most recent SARS-CoV-2 variant of concern (VOC) omicron (B.1.1.529) in general population demonstrate a clear benefit of an additional boost with respect to neutralization capacity, and several national health authorities recommend the fourth vaccination dose.
• Understanding the Risks of Immunosuppression Reduction For Active COVID-19 Infection
  Kidney transplant recipients (KTRs) are at higher risk of mortality and morbidity of COVID-19 infection compared to the general population. Some of this elevated risk comes from non-modifiable factors common to KTRs, such as diabetes, hypertension, and chronic kidney disease.
• Antibody responses to 2 doses of mRNA Covid vaccine in pediatric renal patients
  Studies in adult patients with kidney diseases have shown an attenuated immune response to natural Covid and Covid vaccination. In adolescents, the pivotal trial of BNT162b2 demonstrated a far higher neutralizing antibody titer in adolescents compared with adults
• A fourth dose of the mRNA-1273 SARS-CoV-2 vaccine improves serum neutralization against the delta variant in kidney transplant recipients
  Research has suggested that even three doses of SARS-CoV-2 mRNA-based vaccines might be unable to elicit a sufficient immune response in immunocompromised kidney transplant recipients.
• COVID-19 in dialysis: clinical impact, immune response, prevention and treatment
  The SARS-CoV-2 pandemic has profound adverse effects on the dialysis population. Patients requiring dialysis are at increased risk of SARS-CoV-2 infection and mortality, and many have experienced psychological distress, as well as delayed or suboptimal care.
• Breakthrough Omicron COVID-19 infections in patients receiving REGEN-Cov antibody combination
  COVID-19 vaccines are efficient to prevent severe COVID-19 infections. Immunocompromised patients are at increased risk of both severe COVID-19 and poor immunologic response to anti-SARS-CoV-2 vaccines.
• A fourth SARS-Cov-2 mRNA vaccine in strictly seronegative kidney transplant recipients
  Solid organ transplant recipients have demonstrated a lower humoral immune response to SARS-Cov-2 mRNA vaccination, leading transplant physicians to perform a third vaccine injection.
• A comprehensive assessment of long-term SARS-CoV-2-specific adaptive immune memory in convalescent COVID-19 Solid Organ Transplant recipients
  Long-term adaptive immune memory has been reported among immunocompetent individuals up to eight months following SARS-CoV-2 infection. However, limited data is available in convalescent patients with a solid organ transplant.
• A vector-based vaccine dose after three doses of mRNA-based COVID-19 vaccination does not substantially improve humoral SARS-CoV-2 immunity in renal transplant recipient
  The Coronavirus disease 2019 (COVID-19) related mortality in kidney transplant recipients (KTX) is significantly higher when compared to non-transplant patients. Vaccination against the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) is the most efficient measure to protect this vulnerable population.
• Dialysis staff-reported impact of COVID-19 on early kidney transplant steps
  COVID-19 has influenced multiple aspects of kidney transplantation, the preferred treatment for the majority of patients with end-stage kidney disease (ESKD). Patients with ESKD and transplant recipients are vulnerable to severe COVID-19 illness given the high prevalence of comorbidities and immunosuppression in these populations.
• SARS-CoV-2 vaccination-associated collapsing glomerulopathy in a kidney transplant recipient.
  A stable kidney transplant recipient (KTR) of 14 years received the SARS-CoV-2 ChAdOx1 (AZD1222) vaccine and, within a fortnight, presented with severe acute kidney injury (AKI) -creatinine 533μmol/L (baseline 125-187μmol/L) and nephrotic range proteinuria (urine PCR=2000g/mol, no hematuria).
• REGEN-Cov antibody combination to prevent COVID-19 infection in kidney transplant recipient without detectable antibody response to optimal vaccine scheme
  A large part of kidney transplant recipient (KTR) do not respond to anti-SARS-Cov-2 vaccine. Indeed, concordant data indicate that about thirty percent of KTR do not develop antibodies after three doses of mRNA vaccines.
• Collapsing Glomerulopathy following SARS-CoV-2 adenovirus-vector based vaccine: report of two cases
  In the setting of the rapid spread of the pandemic by the new coronavirus (COVID-19) and the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the kidney was recognized as a frequent target. With the beginning of vaccination for COVID-19, several cases of post-vaccination immunological manifestations have been described.
• Natural SARS-CoV-2 infection results in higher neutralization response against variants of concern compared to two-dose BNT162b2 vaccination in kidney transplant recipients
  Seroconversion rates in kidney transplant recipients (KTR) after two-dose BNT162b2 mRNA vaccination are in the range of 3-59% and thus significantly lower compared to the greater than 90% achieved in healthy controls. In convalescent COVID-19 patients, antibody levels decline only slightly after 6-8 months, whereas vaccine-induced immunity appears to decrease more rapidly.
• The global impact of the Coronavirus 2019 pandemic on in-centre haemodialysis services: an International Society of Nephrology -Dialysis Outcomes Practice Patterns Study survey.

• Humoral response to SARS-CoV-2 in hemodialysis patients
  Patients with end stage renal disease (ESRD) require maintenance dialysis while waiting for a kidney transplant or if not eligible for a transplant. Even with significant improvements in hemodialysis and peritoneal dialysis there is still a high mortality rate. Infections are one of the major causes of death in renal patients requiring dialysis due to an impaired innate and adaptive immune system induced by uremia.
• Immune response to SARS-CoV2 infection and vaccination in patients receiving kidney replacement therapy
  In this issue of the Journal, the initial experience regarding the immunogenicity of prior COVID-19 infection and the response to the COVID-19 vaccines among patients on maintenance dialysis and kidney transplant recipients is summarized.
• Longevity of SARS-CoV-2 immune responses in hemodialysis patients and protection against reinfection
  Patients with end stage kidney disease receiving in-center hemodialysis (ICHD) have had high rates of SARS-CoV-2 infection. Following infection, patients receiving ICHD frequently develop circulating antibodies to SARS-CoV-2, even with asymptomatic infection. Here, we investigated the durability and functionality of the immune responses to SARS-CoV-2 infection in patients receiving ICHD
• Gross hematuria following vaccination for severe acute respiratory syndrome coronavirus 2 in 2 patients with IgA nephropathy
  Several of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines use a nucleoside-modified, purified mRNA lipid nanoparticle-encapsulated platform. Compared with traditional inactivated viral and adjuvanted protein vaccines, this RNA platform elicits far higher neutralizing antibody titers, stronger antigen-specific cluster of differentiation (CD) 4+ and CD8+ T-cell responses, and stronger germinal center B and TFH cell activation in experimental animals.
• Weak anti–SARS-CoV-2 antibody response after the first injection of an mRNA COVID-19 vaccine in kidney transplant recipients
  International recommendations on coronavirus disease 2019 (COVID-19) vaccine distribution have given priority to immunocompromised patients, including kidney transplant recipients (KTRs). Unfortunately, this guidance has been released without inclusion of this clinical population in vaccine clinical trials.
• SARS-CoV-2-reactive cellular and humoral immunity in hemodialysis population
  The outcome of SARS-CoV-2 infection in hemodialysis (HD) patients is significantly worse compared to the general population. Whether the SARS-CoV-2-specific immunity in dialysis patients with COVID-19 is impaired as a possible cause for the inferior outcome is not known so far.
• Low immunization rates among kidney transplant recipients who received two doses of the mRNA-1273 SARS-CoV-2 vaccine
  The efficacy rates of vaccines to prevent infection with SARS-CoV-2 have not been specifically investigated in kidney transplant recipient (KTRs). Preliminary results suggest that among KTRs who received the first injection of an mRNA-based vaccine the antibody response is weak.
• Experience with SARS-COV-2 BNT162b2 mRNA vaccine in dialysis patients
  The immune system is profoundly affected by uremia. End stage kidney disease (ESKD) patients may be more vulnerable to infections and may have suboptimal response to vaccination1. For the SARS-COV-2 (COVID-19), patients with ESKD are at increased risk of infection and mortality.
• Seroprevalence of antibody to S1 spike protein following vaccination against COVID-19 in patients on haemodialysis. A call to arms
  Adult patients with end-stage kidney disease (ESKD) on haemodialysis are at increased risk of coronavirus disease 2019 (COVID-19) infection and death. This group is often multi-racial, suffer from many comorbidities and can be socio-economically deprived; all factors strongly associated with COVID-19 mortality.

  On December 21, 2020, the European Commission granted conditional marketing approval to the BNT162b2 Covid-19 mRNA vaccine developed by BioNTech. In the general population, the first dose of BNT162b2 was reported to produce a rapid antibody response with 52% efficacy in preventing severe infection, similar to the protection induced by the natural disease.
• Bamlanivimab decreases severe outcomes of SARS-CoV-2 infection in ANCA vasculitis patients
  Patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are more likely to have poor outcomes if infected with SARS-CoV-2.
• A Mobile Health-based Survey to Assess COVID-19 Vaccine Intent and Uptake Among Patients on Dialysis
  Patients with kidney failure on dialysis suffer high rates of COVID-19-associated hospitalizations and mortality. Vaccination is crucial to mitigate the risks of COVID-19, but concerningly, one in five patients receiving in-center hemodialysis are vaccine hesitant.
• Association of ethnicity and socioeconomic status with COVID-19 hospitalisation and mortality in those with and without chronic kidney disease
  In the UK, as of July 2021, there have been over 4.5 million confirmed cases of coronavirus disease‐2019 (COVID‐19) and over 150,000 deaths caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) [S1]. Data are being reported on subpopulations most at risk of COVID-19 and its severest forms.
• SARS-CoV-2 vaccine response in ANCA associated vasculitis patients
  The development of COVID-19 vaccines and mass vaccination is a landmark achievement of modern medicine. Management of patients with anti-neutrophil cytoplasmic autoantibodies (ANCA) associated vasculitis (AAV) during the pandemic has been challenging.
• Observations on improving Covid-19 vaccination responses in Kidney Transplant Recipients: heterologous vaccination and immunosuppression modulation
  Solid organ transplant recipients have a weaker humoral response to Covid-19 vaccination due to several factors, including lymphopenia associated with immunosuppressive therapies (particularly Belatacept, antiproliferative drugs and steroids).
• A prospective observational study for justification, safety, and efficacy of a third dose of mRNA vaccine in patients receiving maintenance hemodialysis.
  The level of protection achieved by the standard two doses of COVID-19 mRNA vaccines in patients receiving maintenance hemodialysis (MHD) remains unclear. To study this we used the French Renal Epidemiology and Information Network (REIN) Registry to compare the incidence and severity of 1474 cases of COVID-19 diagnosed in patients receiving MHD after none, one or two doses of vaccine.
• Antibody response to COVID-19 booster vaccine in rituximab treated patients with ANCA associated vasculitis

• The Evolving Practice of Nephrology During the COVID-19 Pandemic in Brunei Darussalam
  Brunei has the fifth highest incidence of kidney failure globally. There have been significant changes to the nephrology practice locally since the second wave of the pandemic in August 2021.
• Elevated NGAL is Associated with the Severity of Kidney Injury and Poor Prognosis of Patients with COVID-19
  Loss of kidney function is a common feature of COVID-19 infection, but serum creatinine (SCr) is not a sensitive or specific marker of kidney injury. We tested whether molecular biomarkers of tubular injury measured at hospital admission were associated with AKI in those with COVID-19 infection.
• A Pilot Study of Urine Proteomics in Covid-19-associated Acute Kidney Injury
  Acute kidney injury (AKI) is a major complication associated with COVID-19 and occurs in up to 76% of intensive care unit patients. The mortality rate of COVID-19 patients who developed AKI (COVID-AKI) is more than 10 times higher than those who did not
• Improved cellular and humoral immunity upon a second BNT162b2 and mRNA-1273 boost in prime-boost vaccination no/low responders with end-stage renal disease
  Patients with end-stage renal disease (ESRD) develop inefficient immune responses upon vaccination and have a high-risk of developing severe COVID-19. The globally expanding SARS-CoV-2 variant of concern (VOC), B.1.6.17.2/Delta, evades immune responses and might constitute a particular threat to these patients.
• Antibody and T cell response to a third dose of SARS-CoV-2 messenger RNA BNT162b2 vaccine in kidney transplant recipients
  SARS-CoV-2 vaccination has become the standard of care for the prevention of severe COVID-19, with a strongly positive impact in countries in which vaccination has been effectively promoted S1. In KTR, SARS-CoV-2 vaccination has been recommended through international guidelines.
• The SARS-CoV-2 neutralizing capacity of kidney transplant recipients four weeks after receiving a second dose of the BNT162b2 vaccine
  COVID-19 vaccinated kidney transplant recipients (KTRs) display a lower-than-normal antibody (Ab) response towards SARS-CoV-2, indicating a reduced humoral immune response against the virus.
• COVID-19 Vaccination Followed by Activation of Glomerular Diseases Does Association Equal Causation?
  To date over 4 billion doses of the various Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) vaccines have been administered worldwide in response to the Coronavirus Disease 2019 (COVID-19) pandemic.
• NAD+ biosynthetic impairment and urinary metabolomic alterations observed in hospitalized adults with COVID-19-related acute kidney injury
  Acute kidney injury (AKI) is common in COVID-19 and associated with increased morbidity and mortality. We investigated alterations in the urine metabolome to test the hypothesis that impaired nicotinamide adenine dinucleotide (NAD+) biosynthesis and other deficiencies in energy metabolism in the kidney, previously characterized in ischemic, toxic, and inflammatory etiologies of AKI, will be present in COVID-19-associated AKI.
• A third vaccine dose substantially improves humoral and cellular SARS-CoV-2 immunity in renal transplant recipients with primary humoral non-response
  Renal transplant recipients (RTR) are at high risk for fatal Coronavirus disease 2019 (COVID-19). Vaccinations are indispensable to protect this vulnerable population. Unfortunately, >50% of solid organ recipients do not mount antibody responses after two doses of SARS-CoV-2-mRNA vaccines.
• COVID-19 vaccine hesitancy in patients on dialysis in Italy and France
  Patients on dialysis (HDP) are a category at high risk from COVID-19 and thus a high-priority group for vaccination. COVID-19 vaccine hesitancy has been a concern since the availability of the first vaccine. The objective of this study was to determine hesitancy rates and factors associated with hesitancy towards COVID-19 vaccination in HDP.
• Impact of rituximab on humoral response to COVID-19 booster vaccine and antibody kinetics in patients with ANCA vasculitis
  The advent of vaccines has resulted in mitigation of severe disease as a consequence of SARS-CoV-2. There is notable absence of humoral absence after two doses of mRNA vaccines in rheumatic and musculoskeletal diseases.
• Casirivimab-Imdevimab (REGN-COV2) for Mild-to-Moderate SARS-CoV2 Infection in Kidney Transplant Recipients.
  Kidney transplant recipients are an immunocompromised population, many with comorbid diseases such as obesity, diabetes, and coronary artery disease, that may increase their risk for developing severe coronavirus disease 2019 (COVID-19).
• Risks factors associated with poor response to COVID-19 vaccination in kidney transplant recipients
  The case fatality ratio of COVID-19 in kidney transplant recipients (KTR) is between 10-30%, underscoring the importance of vaccination to prevent COVID-19. However, KTR have a reduced response to COVID-19 vaccines.
