SARS-CoV-2 Infection in Kidney Transplant Recipients: A Single-Centre Study of 20 Cases from India

Efficacy and Safety of Remdesivir in Adult Solid Organ Transplant Recipients: A Scoping Review

The SARS-CoV-2 infection has been associated with important mortality, particularly in immunocompromised patients, including solid organ transplant (SOT) recipients. Remdesivir (RDV) is an antiviral drug that has proven to be effective in reducing the replication of the virus in host cells, by which it may reduce the progression of symptoms and, consequently, the length of hospital stay and mortality. Randomized controlled trials have evaluated its use in the general population but never in SOT recipients. For the first time in this review, the safety and efficacy of RDV is evaluated in this specific population. The literature research was conducted using PubMed/MEDLINE and Scopus databases from 1 January 2020 to 24 November 2023, and 23 studies were analyzed. Although no clinical studies specifically evaluating this population have been conducted yet, RDV is likely safe for SOT patients when compared to the general population, so prescribers should consider utilizing RDV in SOT patients who are at high risk for progression to severe COVID-19. Future research will allow for the confirmation of the observed results and the acquisition of broader and clearer data regarding the safety and efficacy of the drug in this specific setting.

Factors Associated with COVID-19 Severity Among Kidney Transplant and Non-Kidney Transplant Patients at St. Paul's Hospital Millennium Medical College, Addis Ababa, Ethiopia

Background

The COVID-19 epidemic is a rapidly shifting situation that has resulted in significant regulatory reforms and widespread initiatives to deal with the initial crisis and its effects. The COVID-19 pandemic has had a significant impact on transplantation activities. The COVID-19 pandemic has caused various important challenges in the kidney transplant industry.

Objective

To identify the factors influencing COVID-19 severity in kidney transplant and non-kidney transplant patients at St. Paul's Hospital Millennium Medical College, Addis Ababa, Ethiopia.

Methods

A comparative cross-sectional study was conducted. This study included 364 patients (182 kidney transplants and 182 non-kidney transplants). A systematic random sampling was used to select the respondents. Professional nurses collected data for this study using a data extraction tools. Data were analyzed by using SPSS version 25 software. A multivariable logistic regression analysis was performed to identify the association between independent variables and COVID-19 severity with adjusted odds ratio (AOR), and 95% CI for AOR and P-value for testing significance.

Results

This study included 364 patients. Off the total, 34.1% developed severe COVID-19. In Multivariable logistic regression analysis, patients with 60 years and above age groups (AOR = 4.73; 95% CI: 1.86, 12.02), aged 40-59 years (AOR = 2.70; 95% CI: 1.17, 6.22), chest congestion (AOR = 4.49; 95% CI: 2.37, 8.50), history of muscle or body aches (AOR = 0.47; 95% CI: 0.22, 0.99) shortness of breath (AOR = 3.03; 95% CI: 1.36, 6.74), changed or lost sense of taste or smell (AOR = 2.77; 95% CI: 1.34, 5.71), and muscle pain (AOR = 3.05; 95% CI: 1.40, 6.65) were significant variables associated with COVID-19 severity after adjusting for other variables.

Conclusion

The study revealed that 34.1% of patients had severe COVID-19. The majority of these patients underwent non-kidney transplants. Age groups and symptoms, such as chest congestion, shortness of breath, changed or lost sense of taste or smell, and muscle pain, were significant predictors of COVID-19 disease severity.

Remdesivir Administration in COVID-19 Patients With Renal Impairment: A Systematic Review

BACKGROUND

Remdesivir (RDV) is the main antiviral for the treatment of moderate to severe forms of Coronavirus disease 2019 (COVID-19). Several studies revealed a shortening time to clinical improvement of COVID-19 and mortality benefits in patients receiving RDV. The patients with renal disease were excluded from large clinical trials of RDV, and the probable nephrotoxicity of the drug, its metabolites, and the vehicle (sulfobutylether-β-cyclodextrin) have led to the recommendation against using RDV in patients with an estimated glomerular filtration rate of <30 mL/min.

AREAS OF UNCERTAINTY

This systematic review aimed to collect data about the necessity and safety administration of RDV in the setting of renal impairment.

DATA SOURCES

Search through databases including MEDLINE, ScienceDirect, Cochrane Library, and PubMed was performed. The studies were carried out in adults and enrolled patients with different types of renal impairment (ie, acute kidney injury, chronic kidney disease, kidney transplant, and renal replacement therapy) were included. Eligible studies were assessed, and required data were extracted.

RESULTS

Twenty-two cross-sectional studies, cohorts, case reports, and case series were included in this review. The mortality rate was between 7.3% and 50%, and various severity of COVID-19 was included in the studies. None of them reported an increase in adverse effects attributed to RDV administration. A decrease in inflammatory mediators and other benefits were obvious.

CONCLUSIONS

Although the manufacturer's labeling does not recommend RDV administration in patients with severe renal impairment, it seems that nephrotoxicity is less concerning in the population of these patients. Moreover, RDV may be helpful in acute kidney injury induced by the viral invasion of COVID-19. To the best of our knowledge, this is the first systematic review of the use of RDV in kidney failure. Larger, well-designed, and pharmacokinetic studies are required to have a safe and logical recommendation about the use of RDV in patients with renal disorders.

A Comprehensive Comparison of Clinical Presentation and Outcomes of Kidney Transplant Recipients with COVID-19 during Wave 1 versus Wave 2 at a Tertiary Care Center, India

Data comparing the clinical spectrum of COVID-19 in kidney transplant recipients (KTRs) during the first and second waves of the pandemic in India is limited. Our single-center retrospective study compared the clinical profile, mortality, and associated risk factors in KTRs with COVID-19 during the 1st wave (1^st February 2020 to 31^st January 2021) and the second wave (1^st March-31^st August 2021). 156 KTRs with PCR confirmed SARS-CoV-2 infection treated at a tertiary care hospital in New Delhi during the 1st and the second waves were analyzed. The demographics and baseline transplant characteristics of the patients diagnosed during both waves were comparable. Patients in the second wave reported less frequent hospitalization, though the intensive care unit (ICU) and ventilator requirements were similar. Strategies to modify immunosuppressants such as discontinuation of antinucleoside drugs with or without change in calcineurin inhibitors and the use of steroids were similar during both waves. Overall patient mortality was 27.5%. The demographics and baseline characteristics of survivors and nonsurvivors were comparable. A higher percentage of nonsurvivors presented with breathing difficulty, low SpO₂, and altered sensorium. Both wave risk factors for mortality included older age, severe disease, ICU/ventilator requirements, acute kidney injury (AKI) needing dialysis, Chest Computerized Tomographic (CT) scan abnormalities, and higher levels of inflammatory markers particularly D-dimer and interleukin-6 levels. Conclusions. KTRs in both COVID-19 waves had similar demographics and baseline characteristics, while fewer patients during the second wave required hospitalization. The D-dimer and IL-6 levels are directly correlated with mortality.
