COVID-19 and Kidney Disease Disparities in the United States

A narrative review on adverse drug reactions of COVID-19 treatments on the kidney

Studies showed that the respiratory is not the only system affected by coronavirus 2, while cardiovascular, digestive, and nervous systems, as well as essential organs such as the kidneys, can be affected by this virus. In this review, we have studied the epidemiology, clinical, and laboratory findings on COVID-19 infection renal involvement, mortality, physiopathology, remaining renal sequels after recovery, underlying renal disease, and renal injury due to its treatment. Also, protective measures for kidney injury are explained in three levels. Evidence of viral particles and genome in the urine and renal tubular cells and signs of damage such as microangiopathy, hypercoagulopathy, and fibrosis are found in COVID-19 patients. The result of this study showed, in hospitalized COVID-19 patients, that the rate of acute kidney injury (AKI) was up to 46%, with a mortality ranging from 11 to 96%. A considerable proportion of patients with AKI would remain on renal replacement therapy. Proteinuria and hematuria are observed in 87 and 75% patients, and increased Cr and glomerular filtration rate (GFR) <60 ml/min per 1.73 m2 are observed in 29.6 and 35.3% of the patients, respectively. Remedsivir is considered to have adverse effects on GFR. COVID-19 patients need special attention to prevent AKI. Those with underlying chronic kidney disease or AKI need proper and explicit evaluation and treatment to improve their prognosis and decrease mortality, which should not be limited to the hospitalization period.

Comorbidity patterns in cardiovascular diseases: the role of life-stage and socioeconomic status

Cardiovascular diseases stand as a prominent global cause of mortality, their intricate origins often entwined with comorbidities and multimorbid conditions. Acknowledging the pivotal roles of age, sex, and social determinants of health in shaping the onset and progression of these diseases, our study delves into the nuanced interplay between life-stage, socioeconomic status, and comorbidity patterns within cardiovascular diseases. Leveraging data from a cross-sectional survey encompassing Mexican adults, we unearth a robust association between these variables and the prevalence of comorbidities linked to cardiovascular conditions. To foster a comprehensive understanding of multimorbidity patterns across diverse life-stages, we scrutinize an extensive dataset comprising 47,377 cases diagnosed with cardiovascular ailments at Mexico's national reference hospital. Extracting sociodemographic details, primary diagnoses prompting hospitalization, and additional conditions identified through ICD-10 codes, we unveil subtle yet significant associations and discuss pertinent specific cases. Our results underscore a noteworthy trend: younger patients of lower socioeconomic status exhibit a heightened likelihood of cardiovascular comorbidities compared to their older counterparts with a higher socioeconomic status. By empowering clinicians to discern non-evident comorbidities, our study aims to refine therapeutic designs. These findings offer profound insights into the intricate interplay among life-stage, socioeconomic status, and comorbidity patterns within cardiovascular diseases. Armed with data-supported approaches that account for these factors, clinical practices stand to be enhanced, and public health policies informed, ultimately advancing the prevention and management of cardiovascular disease in Mexico.

Structural and Psychosocial Challenges Among Underserved Patients Receiving Hemodialysis During and Beyond the COVID-19 Pandemic: A Qualitative Study

Rationale & Objective

Racial and ethnic minority groups in the United States are disproportionately affected by chronic kidney disease and progressive kidney failure and face significantly more socioeconomic and psychosocial challenges. However, how such patients' social environment and stigmatization shape their illness experiences and abilities to cope before and during the coronavirus disease 2019 (COVID-19) pandemic has not been well documented, even as social scientific research predicts these groups' exponential vulnerability.

Study Design

Qualitative study using semistructured interviews to elicit individual patient narratives about their personal illness experiences before and during the COVID-19 pandemic, any challenges they faced, and their sources of support.

Setting & Participants

Using purposive sampling, we recruited 20 adult patients receiving maintenance hemodialysis from centers affiliated with a safety-net hospital in Boston, Massachusetts.

Analytical Approach

Interviews were audiotaped, transcribed, and analyzed using thematic content analysis to identify patients' challenges and supports before and during the pandemic.

Results

Of the 20 patients in the study, 9 were women, and 18 self-identified as Black or African American. Three main themes emerged, whereby most patients described: (1) stigma and stigmatization as a central element of their life experience; (2) the pandemic as a difficult experience but not a complete rupture from their prepandemic life; and (3) social networks, particularly family, friends, and religious communities, as sources of support crucial to coping with their debilitating illness.

Limitations

Whether the findings apply to other settings is unknown, as participants were recruited from centers in a single safety-net urban hospital setting.

Conclusions

Psychosocial and environmental factors, including institutional racism and stigmatization, play significant roles in amplifying the burdens shouldered by racial and ethnic minority individuals with kidney disease who now also face the COVID-19 pandemic that has since turned endemic. The results of this study can inform the development of policy interventions aimed at alleviating tensions and structural conditions that impinge on kidney disease patients' wellbeing and health outcomes.

Plain-Language Summary

Members of racial and ethnic minority groups in the United States experience the highest rates of progressive kidney failure and face significantly more socioeconomic and psychosocial challenges. We interviewed 20 patients who receive maintenance hemodialysis treatment from centers affiliated with a safety-net hospital. Patients described stigmatization as a central element of their life experience and the pandemic as a difficult challenge (but not a complete rupture) that added to their struggles with illness-related, race-related, and class-related stigmas. Social networks, particularly family, friends, and religious communities, are key sources of support crucial to coping with illness. Findings from this study can inform health care providers and community workers and guide the development of policy interventions to provide better support for these patients.

Current trends in hospice care usage for dialysis patients in the USA

BACKGROUND

The predictors and latest trends in hospice utilization, adequate duration of hospice care, and dialysis discontinuation without hospice enrollment among patients with end stage kidney disease are not fully known; the aim of this study was to assess them, analysing data from the United States Renal Data System.

METHODS

Data from the United States Renal Data System for patients with kidney failure who died between January 1, 2012, and December 31, 2019, were analyzed. Chi-square and logistic regression were used to evaluate associations between outcomes of interest and predictors, while Joinpoint regression was used to examine trends.

RESULTS

Among 803,049 patients, the median (IQR) age was 71 (17) years, 57% were male, 27% enrolled in hospice, 8% discontinued dialysis before death without hospice enrollment, and 7% remained in hospice for ≥ 15 days. Patients 65 years and older (adjusted odds ratio [aOR]: 2.75, 95% CI 2.71-2.79) and White race (aOR: 1.79, 95% CI 1.77-1.81) were more likely to enroll in hospice. White patients (aOR: 0.75, 95% CI 0.73-0.76) and those who never received a kidney transplant (aOR: 0.75, 95% CI 0.73-0.78) were less likely to have adequate duration of hospice care. Hospice enrollment and standardized duration of hospice care increased over time, with an average annual percentage change of 1.1% (95% CI 0.6-1.6) and 5% (95% CI 2.6-7.4), respectively.

CONCLUSIONS

Approximately one in every four patients with kidney failure who died between 2012 and 2019 had a history of hospice enrollment, while one in every 12 discontinued dialysis before death without hospice enrollment. There was an upward trend in the duration of hospice care.

Social Determinants of Health Impacting Access to Renal Dialysis for Racial/Ethnic Minorities

Although widespread, the burden of disease presented by chronic kidney disease (CKD) is not equally distributed among all demographics. Examining the social determinants of health (SDOH) that relate to barriers to renal dialysis care in CKD can help to prevent future disparities. There has not been a study addressing the social factors that create barriers to care for ethnic minority patients with CKD. The aim of this scoping review is to address the SDOH that affects access to renal dialysis for ethnic minority patients in the United States. This study was based on the protocol published by the Joanna Briggs Institute. A total of 349 studies were identified from PubMed, EBSCOhost, and Embase. Each article was screened against population, concept, and context criteria in order to be considered for inclusion. The population was determined to be adults of all genders from underrepresented minority populations. The selected concept was SDOH. The context of this study was the United States population. From the articles selected by the search criteria, neighborhood of residence, mental health care access, glomerular filtration rate (GFR) methodology, socioeconomic status (SES), language barriers, immigration status, and military rank were identified as SDOH affecting access to renal dialysis care. While this study identified four social determinants, more research is needed for the investigation of other possible SDOH contributing to disparities related to CKD and access to renal dialysis care.

Impact of the COVID-19 pandemic on access to healthcare, physical and mental health among patients with chronic kidney disease in Victoria, Australia

PURPOSE

The COVID-19 pandemic has highlighted the difficulties healthcare systems face to care for patients with chronic diseases. In the state of Victoria, Australia, the government implemented a state-wide lockdown and restricted the delivery of healthcare to limit the spread of the virus. This study investigated the impact of the pandemic on healthcare access, mental and physical health for patients with chronic kidney disease (CKD).

METHODS

Patients with stage 4 or 5 CKD were recruited from the nephrology unit of a metropolitan hospital in Victoria. Participants completed a quantitative and qualitative questionnaire that assessed the impact of the pandemic on their access to healthcare and mental and physical health. The quantitative data were analysed by a series of one-way between-groups analysis of variance (ANOVAs) comparing impact between different time periods since the beginning of the pandemic.

RESULTS

Participants (n = 75) completed the questionnaire from 30 March 2020 to 29 September 2021. Participants reported significant disruptions to accessing healthcare in the initial 6 months of the pandemic. There were no significant differences in the quantitative assessments of physical and mental health of participants across the 18 months of this study. The participants' qualitative comments about disrupted normal activities, feeling vulnerable to COVID-19, transitioning to telehealth, feeling isolated and vaccination protection provided further insight into the cumulative negative mental health impact of the extended lockdown.

CONCLUSION

Our findings highlight the importance of optimising telehealth to improve communication between CKD patients and their treating teams and continuing to monitor the impacts of pandemic restrictions on patients' mental and physical health.

Association of Time to Surgery After COVID-19 Infection With Risk of Postoperative Cardiovascular Morbidity

IMPORTANCE

The time interval between COVID-19 infection and surgery is a potentially modifiable but understudied risk factor for postoperative complications.

OBJECTIVE

To examine the association between time to surgery after COVID-19 diagnosis and the risk of a composite of major postoperative cardiovascular morbidity events within 30 days of surgery.

DESIGN, SETTING, AND PARTICIPANTS

This single-center, retrospective cohort study was conducted among 3997 adult patients (aged ≥18 years) with a previous diagnosis of COVID-19, as documented by a positive polymerase chain reaction test result, who were undergoing surgery from January 1, 2020, to December 6, 2021. Data were obtained through Structured Query Language access of an existing perioperative data warehouse. Statistical analysis was performed March 29, 2022.

EXPOSURE

The time interval between COVID-19 diagnosis and surgery.

MAIN OUTCOMES AND MEASURES

The primary outcome was the composite occurrence of major cardiovascular comorbidity, defined as deep vein thrombosis, pulmonary embolism, cerebrovascular accident, myocardial injury, acute kidney injury, and death within 30 days after surgery, using multivariable logistic regression.

RESULTS

A total of 3997 patients (2223 [55.6%]; median age, 51.3 years [IQR, 35.1-64.4 years]; 667 [16.7%] African American or Black; 2990 [74.8%] White; and 340 [8.5%] other race) were included in the study. The median time from COVID-19 diagnosis to surgery was 98 days (IQR, 30-225 days). Major postoperative adverse cardiovascular events were identified in 485 patients (12.1%). Increased time from COVID-19 diagnosis to surgery was associated with a decreased rate of the composite outcome (adjusted odds ratio, 0.99 [per 10 days]; 95% CI, 0.98-1.00; P = .006). This trend persisted for the 1552 patients who had received at least 1 dose of COVID-19 vaccine (adjusted odds ratio, 0.98 [per 10 days]; 95% CI, 0.97-1.00; P = .04).

CONCLUSIONS AND RELEVANCE

This study suggests that increased time from COVID-19 diagnosis to surgery was associated with a decreased odds of experiencing major postoperative cardiovascular morbidity. This information should be used to better inform risk-benefit discussions concerning optimal surgical timing and perioperative outcomes for patients with a history of COVID-19 infection.

Effects of vaccination, new SARS-CoV-2 variants and reinfections on post-COVID-19 complications

Post-COVID-19 complications involve a variety of long-lasting health complications emerging in various body systems. Since the prevalence of post-COVID-19 complications ranges from 8-47% in COVID-19 survivors, it represents a formidable challenge to COVID-19 survivors and the health care system. Post-COVID-19 complications have already been studied in the connection to risk factors linked to their higher probability of occurrence and higher severity, potential mechanisms underlying the pathogenesis of post-COVID-19 complications, and their functional and structural correlates. Vaccination status has been recently revealed to represent efficient prevention from long-term and severe post-COVID-19 complications. However, the exact mechanisms responsible for vaccine-induced protection against severe and long-lasting post-COVID-19 complications remain elusive. Also, to the best of our knowledge, the effects of new SARS-CoV-2 variants and SARS-CoV-2 reinfections on post-COVID-19 complications and their underlying pathogenesis remain to be investigated. This hypothesis article will be dedicated to the potential effects of vaccination status, SARS-CoV-2 reinfections, and new SARS-CoV-2 variants on post-COVID-19 complications and their underlying mechanisms Also, potential prevention strategies against post-COVID complications will be discussed.

Treatment Decision Making for Older Kidney Patients during COVID-19

BACKGROUND AND OBJECTIVES

Coronavirus disease 2019 (COVID-19) disrupted medical care across health care settings for older patients with advanced CKD. Understanding how shared decision making for kidney treatment decisions was influenced by the uncertainty of an evolving pandemic can provide insights for supporting shared decision making through the current and future public health crises.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We performed thematic and narrative analyses of semistructured interviews with patients (CKD stages 4 and 5, age 70+), care partners, and clinicians from Boston, Portland (Maine), San Diego, and Chicago from August to December 2020.

RESULTS

We interviewed 76 participants (39 patients, 17 care partners, and 20 clinicians). Among patient participants, 13 (33%) patients identified as Black, and seven (18%) had initiated dialysis. Four themes with corresponding subthemes emerged related to treatment decision making and the COVID-19 pandemic: (1) adapting to changed educational and patient engagement practices (patient barriers to care and new opportunities for telemedicine); (2) reconceptualizing vulnerability (clinician awareness of illness severity increased and limited discussions of patient COVID-19 vulnerability); (3) embracing home-based dialysis but not conservative management (openness to home-based modalities and limited discussion of conservative management and advanced care planning); and (4) satisfaction and safety with treatment decisions despite conditions of uncertainty.

CONCLUSIONS

Although clinicians perceived greater vulnerability among older patients CKD and more readily encouraged home-based modalities during the COVID-19 pandemic, their discussions of vulnerability, advance care planning, and conservative management remained limited, suggesting areas for improvement. Clinicians reported burnout caused by the pandemic, increased time demands, and workforce limitations, whereas patients remained satisfied with their treatment choices despite uncertainty.

County-Level Dialysis Facility Supply and Distance Traveled to Facilities among Incident Kidney Failure Patients

Background

The availability of dialysis facilities and distance traveled to receive care can impact health outcomes for patients with newly onset kidney failure. We examined recent changes in county-level number of dialysis facilities between 2012 and 2019 and assessed the association between county-level dialysis facility supply and the distance incident kidney failure patients travel to receive care.

Methods

We conducted a cross-sectional study of 828,427 adult patients initiating in-center hemodialysis for incident kidney failure between January 1, 2012, and December 31, 2019. We calculated the annual county-level number of dialysis facilities, and counties were categorized as having zero, one, two, or three or more dialysis facilities at the time of treatment initiation. We then measured the distance traveled between a patient's home address and dialysis facility at treatment initiation (in miles) and evaluated the association between county-level number of dialysis facilities and distance traveled to initiate treatment.

Results

The average annual county-level number of facilities increased from 1.8 to 2.3 between 2012 and 2019. In our study period, 5% of incident adult kidney failure patients resided in a county that had zero dialysis facilities between 2012 and 2019. Compared with counties with three or more dialysis facilities, patients living in counties with no facilities in our study period traveled 14.3 miles (95% CI, 13.4 to 15.2) further for treatment.

Conclusions

Kidney failure patients in counties that had no dialysis facilities traveled further, limiting their access to dialysis. Counties with no dialysis facilities at the end of the study period were more rural and had higher poverty than other counties.

Tackling Ethnic Health Disparities Through Community Health Worker Programs: A Scoping Review on Their Utilization During the COVID-19 Outbreak

The coronavirus disease (COVID-19) outbreak has magnified existing health inequities linked to social determinants of health, with racial and ethnic minorities being disproportionately affected by the pandemic. A proposed strategy to address these inequities is based on the implementation of community health worker (CHW) programs able to bridge the gaps between marginalized communities and the formal health care systems. A scoping review was conducted through searching 4 databases: PubMed, Scopus, Web of Science, and Science Direct. Inclusion criteria focused on studies defining any kind of adopted CHW intervention to address inequities related to racial/ethnic groups during the COVID-19 crisis, published from December 31, 2019, to October 31, 2021. Narrative synthesis was undertaken to summarize the findings. In total, 23 studies met the inclusion out of the 107 search results. Data converged on the relevant potential of CHWs on engaging with community leaders, addressing social determinants of health, and issues related to structural racism, promoting culturally tailored health information, and encouraging institutions to policy change in favor of people left behind. Although vulnerability of racial and ethnic minorities was already present before the COVID-19 outbreak, the pandemic has represented a wakeup call to address it more efficiently. In recent years, CHWs have increasingly been acknowledged as valuable members of the health care workforce. As health disparities may increase after our multicultural societies begin to recover from COVID-19, CHWs may play a crucial role in addressing system-level changes to have broad and lasting effects on health outcomes.

Disparities in Mental Health and Well-Being Among Black and Latinx Patients With Kidney Disease

Black and Latinx individuals in the United States are afflicted disproportionately with kidney disease. Because of structural racism, social risk factors drive disparities in disease prevalence and result in worse outcomes among these patient groups. The impact of social and economic oppression is pervasive in physical and emotional aspects of health. In this review, we describe the history of race and ethnicity among black and Latinx individuals in the United States and discuss how these politicosocial constructs impact disparities in well-being and mental health. Lastly, we outline future research, clinical considerations, and policy considerations to eliminate racial and ethnic disparities in well-being among black and Latinx individuals with kidney disease.

Despite National Declines In Kidney Failure Incidence, Disparities Widened Between Low- And High-Poverty US Counties

National estimates suggest that kidney failure incidence is declining in the US. However, whether this trend is evident in areas with socioeconomic disadvantage is unknown. We examined trends in kidney failure incidence by county-level poverty between 2000 and 2017 and divided the study period into period 1 (2000-05), period 2 (2006-11), and period 3 (2012-17). The magnitude of disparity in kidney failure incidence between high- and low-poverty counties increased from 42.8 more incident cases per million in high-poverty counties in period 1 to 100.1 more in period 3. Despite a national decline, kidney failure incidence increased in high-poverty counties, and disparities between high- and low-poverty counties widened from 2000 to 2017. Achieving the Department of Health and Human Services objective of reducing incident kidney failure cases by 25 percent by 2030 will require focused attention on preventing kidney failure in counties with higher poverty.

Renal involvement in COVID-19: focus on kidney transplant sector

INTRODUCTION

Kidney transplant recipients and patients on the waiting list for kidney transplant who acquire SARS-CoV-2 infection are at serious risk of developing severe COVID-19, with an increased risk of mortality for the their immunosuppressive state; other risk factors for mortality have been identified in some comorbidities such as obesity, diabetes, asthma and chronic lung disease.

MATERIALS AND METHODS

The COVID-19 pandemic has led to a sharp reduction in kidney transplants in most countries, mainly due to the concern of patients on the waiting list for their potential increased susceptibility to acquire SARS-CoV-2 infection in healthcare facilities and for the difficulties of transplant centers to ensure full activity as hospitals have had to focus most of their attention on COVID-19 patients. Indeed, while the infection curve continued its exponential rise, there was a vertical decline in kidney donation/transplant activity.

CONCLUSION

This review article focuses on the damage induced by SARS-CoV-2 infection on kidney and on the adverse effect of this pandemic on the entire kidney transplant sector.

The frail world of haemodialysis patients in the COVID-19 pandemic era: a systematic scoping review

BACKGROUND

Patients undergoing in-centre haemodialysis (HD) are particularly exposed to the dire consequences of COVID-19. The present systematic scoping review aims to identify the extent, range, and nature of articles related to COVID-19 and maintenance HD: it reports specifically the prevalence of the COVID-19 pandemic in the HD population, implementation of strategies for the prevention, mitigation and containment of the COVID-19 pandemic in HD centres, demographic and clinical characteristics, and outcomes of the pediatric and adult HD patients.

METHODS

A multi-step systematic search of the literature in Pubmed, Scopus, Ovid Medline, Embase and Web of Science, published between December 1, 2019, and January 30, 2021 was performed. Two authors separately screened the titles and abstracts of the documents and ruled out irrelevant articles. A report of the papers that met inclusion criteria was performed; then, a descriptive analysis of the characteristics of the included articles and a narrative synthesis of the results were performed.

RESULTS

The review process ended with the inclusion of 145 articles. Most of them were based on single-centre experiences, which spontaneously developed best practices. Most studies were conducted in high-income countries (69.7%) and a part of them (9.6%) were not in English. Prevalence of COVID-19 among dialysis patients accounted for 0%-37.6%. Preventive measures were reported in 54% of the included articles, with particular emphasis on education, triage, hygiene, and containment measures. Patients experienced a heterogeneous spectrum of symptoms that led 35%-88.2% of them to hospital admission. Median and mean hospital length of stay ranged from 8 to 28.5 and 16.2 to 22 days, respectively. Admission to intensive care units varied widely across studies (from 2.6% to 70.5%) and was associated with high mortality (42.8%-100%). Overall, prognosis was poor in 0%-47% of the hospitalized patients.

CONCLUSIONS

This systematic scoping review provides an overview of the current knowledge on the impact of COVID-19 on the frail world of HD patients. Furthermore, it may help to implement the existing strategies of COVID-19 prevention and provide a list of unmet needs (safe transport, testing, shelter). Finally, it may be a stimulus for performing systematic reviews and meta-analyses which will form the basis for evidence-based guidelines.

Impact of Social Determinants and Digital Literacy on Telehealth Acceptance for Pediatric Cardiology Care Delivery during the Early Phase of the COVID-19 Pandemic

OBJECTIVES

To determine whether telehealth acceptance by parents of children with heart disease is predicted by sociodemographic and/or by parental digital literacy, and to assess parental perceptions of telehealth usability and reliability.

STUDY DESIGN

We conducted a single center study comparing telehealth acceptance versus visit cancellation/rescheduling for pediatric cardiology visits during the early phase of the COVID-19 pandemic. All parent/guardians who consented to survey completion received a validated survey assessing their digital literacy. Consenting parents who accepted telehealth received an additional validated survey assessing their perceptions of telehealth usability and reliability.

RESULTS

A total of 849 patients originally were scheduled for in-person visits between March 30 and May 8, 2020. Telehealth acceptance was highest among younger, publicly insured, Hispanic patients with primary diagnoses of arrhythmia/palpitations, chest pain, dysautonomia, dyslipidemia and acquired heart disease. Among parents who completed surveys, a determinant of telehealth acceptance was digital literacy. Telehealth was determined to be a usable and reliable means for health care delivery.

CONCLUSION

Although the potential for inequitable selection of telehealth due to sociodemographic factors exists, we found that such factors were not a major determinant for pediatric cardiology care within a large, diverse, free-standing pediatric hospital.

Evaluation of Racial, Ethnic, and Socioeconomic Disparities in Initiation of Kidney Failure Treatment During the First 4 Months of the COVID-19 Pandemic

Importance

Persons with kidney failure require treatment (ie, dialysis or transplantation) for survival. The burden of the COVID-19 pandemic and pandemic-related disruptions in care have disproportionately affected racial and ethnic minority and socially disadvantaged populations, raising the importance of understanding disparities in treatment initiation for kidney failure during the pandemic.

Objective

To examine changes in the number and demographic characteristics of patients initiating treatment for incident kidney failure following the COVID-19 pandemic by race and ethnicity, county-level COVID-19 mortality rate, and neighborhood-level social disadvantage.

Design, Setting, and Participants

This cross-sectional time-trend study used data from US patients who developed kidney failure between January 1, 2018, and June 30, 2020. Data were analyzed between January and July 2021.

Exposures

COVID-19 pandemic.

Main Outcomes and Measures

Number of patients initiating treatment for incident kidney failure and mean estimated glomerular filtration rate (eGFR) at treatment initiation.

Results

The study population included 127 149 patients with incident kidney failure between January 1, 2018, and June 30, 2020 (mean [SD] age, 62.8 [15.3] years; 53 021 [41.7%] female, 32 932 [25.9%] non-Hispanic Black, and 19 835 [15.6%] Hispanic/Latino patients). Compared with the pre-COVID-19 period, in the first 4 months of the pandemic (ie, March 1 through June 30, 2020), there were significant decreases in the proportion of patients with incident kidney failure receiving preemptive transplantation (1805 [2.1%] pre-COVID-19 vs 551 [1.4%] during COVID-19; P < .001) and initiating hemodialysis treatment with an arteriovenous fistula (2430 [15.8%] pre-COVID-19 vs 914 [13.4%] during COVID-19; P < .001). The mean (SD) eGFR at initiation declined from 9.6 (5.0) mL/min/1.73 m2 to 9.5 (4.9) mL/min/1.73 m2 during the pandemic (P < .001). In stratified analyses by race/ethnicity, these declines were exclusively observed among non-Hispanic Black patients (mean [SD] eGFR: 8.4 [4.6] mL/min/1.73 m2 pre-COVID-19 vs 8.1 [4.5] mL/min/1.73 m2 during COVID-19; P < .001). There were significant declines in eGFR at initiation for patients residing in counties in the highest quintile of COVID-19 mortality rates (9.5 [5.0] mL/min/1.73 m2 pre-COVID-19 vs 9.2 [5.0] mL/min/1.73 m2 during COVID-19; P < .001), but not for patients residing in other counties. The number of patients initiating treatment for incident kidney failure was approximately 30% lower than projected in April 2020.

Conclusions and Relevance

In this cross-sectional study of US adults, the COVID-19 pandemic was associated with a substantially lower number of patients initiating treatment for incident kidney failure and treatment initiation at lower levels of kidney function during the first 4 months, particularly for Black patients and people living in counties with high COVID-19 mortality rates.

Perspectives on Kidney Disease Education and Recommendations for Improvement Among Latinx Patients Receiving Emergency-Only Hemodialysis

IMPORTANCE

In most states, undocumented Latinx immigrants with kidney failure receive dialysis in acute care settings on an emergency-only basis. How much kidney disease education Latinx immigrants receive and how to improve kidney disease education and outreach among Latinx populations are unknown.

OBJECTIVE

To understand the kidney disease educational gaps of Latinx individuals who need but lack access to scheduled outpatient dialysis.

DESIGN, SETTING, AND PARTICIPANTS

This qualitative study used semistructured interviews in a Texas hospital system from March 2020 to January 2021 with 15 individuals who received emergency-only dialysis when they were first diagnosed with kidney failure. Demographic information was collected, and a thematic analysis was performed using the constant comparative method on interviews after they were audio-recorded, translated, and transcribed verbatim. Data analysis was performed from April 2020 to February 2021.

MAIN OUTCOMES AND MEASURES

Subthemes and themes from semistructured interviews.

RESULTS

All 15 persons interviewed (9 male individuals [60%]; mean [SD] age, 51 [17] years) identified as Hispanic, 11 (73%) were born in Mexico, and none reported knowing about their kidney disease more than 6 months before starting dialysis. The themes identified were (1) lack of kidney disease awareness, (2) education provided was incomplete and poor quality, (3) lack of culturally concordant communication and care, (4) elements that Latinx patients receiving emergency-only dialysis want in their education, (5) facilitators of patient activation and coping, and (6) Latinx patient recommendations to improve community outreach.

CONCLUSIONS AND RELEVANCE

Latinx adults receiving emergency-only dialysis are usually unaware of their kidney disease until shortly before or after they start dialysis, and the education they receive is poor quality and often not culturally tailored. Participants made feasible recommendations on how to improve education and outreach among Latinx communities.

[Epidemiologic and clinical profile, 90 days survival of incident end stage renal patient in haemodialysis during SARS-CoV2 pandemic: Experience of the General Hospital of Douala]

BACKGROUND

The effect of COVID-19 pandemic on end stage renal disease patient who should initiated dialysis are limited in Sub-Saharan Africa is unknown. We sought to describe the epidemiologic and clinical profile of newly admitted patient in chronic haemodialysis during the COVID-19 pandemic in Cameroon and evaluate their survival between 90days of dialysis initiation.

MATERIAL AND METHOD

We conducted a cohort study of 6months from April to October 2020. End stage renal disease patients newly admitted in the haemodialysis facility of the General Hospital of Douala were included. Patients with confirmed or suspected COVID-19 were identified. Socio-demographic, clinical and biological data at dialysis initiation as well as mortality between the 90days of dialysis initiation were registered.

RESULTS

A total of 57 incident patients were recorded from April to October 2020 with a monthly mean of 9.5 patients. The mean age was 46.95±13.12years. Twenty-four COVID-19 were identified with a frequency of 49% among emergency admission. Pulmonary œdema (79.2% vs. 42.4%; P=0.006) and uremic encephalopathy (83.4% vs. 53.6%; P=0.022) were more common in COVID-19. The overall survival at 90days was 48% with a tendency to poor survival among COVID-19 and patients with low socioeconomic level. In Cox regression, low socioeconomic level increase the risk of instant death by 3.08.

CONCLUSION

SARS-CoV2 seem to increase nephrology emergency and poor survival in haemodialysis at 90days.

Aging and COVID-19 in Minority Populations: a Perfect Storm

PURPOSE OF REVIEW

COVID-19 is a major concern for the health and wellbeing of individuals worldwide. As COVID-19 cases and deaths continue to increase in the USA, aging Black and Hispanic populations have emerged as especially at-risk for increased exposure to COVID-19 and susceptibility to severe health outcomes. The current review discusses the weathering hypothesis and the influence of social inequality on the identified health disparities.

RECENT FINDINGS

Aging minoritized populations have endured structural and social inequality over the lifecourse. Consequently, these populations experience weathering, a process that results in physiological dysregulation due to stress associated with persistent disadvantage. Through weathering and continued inequity, aging minoritized populations have an increased risk of exposure and poor health outcomes from COVID-19.

SUMMARY

Current literature and available data suggests that aging minoritized persons experience high rates of COVID-19 morbidity and mortality. The current review hypothesizes and supports that observed disparities are the result of inequalities that especially affect Black and Hispanic populations over the lifecourse. Future efforts to address these disparities should emphasize research that supports governments in identifying at-risk groups, providing accessible COVID-19-related information to those groups, and implementing policy that addresses the structural and social inequities that perpetuate current COVID-19 disparities.

Severe Acute Respiratory Syndrome Coronavirus 2, COVID-19, and the Renin-Angiotensin System: Pressing Needs and Best Research Practices

The coronavirus disease 2019 (COVID-19) pandemic is associated with significant morbidity and mortality throughout the world, predominantly due to lung and cardiovascular injury. The virus responsible for COVID-19-severe acute respiratory syndrome coronavirus 2-gains entry into host cells via ACE2 (angiotensin-converting enzyme 2). ACE2 is a primary enzyme within the key counter-regulatory pathway of the renin-angiotensin system (RAS), which acts to oppose the actions of Ang (angiotensin) II by generating Ang-(1-7) to reduce inflammation and fibrosis and mitigate end organ damage. As COVID-19 spans multiple organ systems linked to the cardiovascular system, it is imperative to understand clearly how severe acute respiratory syndrome coronavirus 2 may affect the multifaceted RAS. In addition, recognition of the role of ACE2 and the RAS in COVID-19 has renewed interest in its role in the pathophysiology of cardiovascular disease in general. We provide researchers with a framework of best practices in basic and clinical research to interrogate the RAS using appropriate methodology, especially those who are relatively new to the field. This is crucial, as there are many limitations inherent in investigating the RAS in experimental models and in humans. We discuss sound methodological approaches to quantifying enzyme content and activity (ACE, ACE2), peptides (Ang II, Ang-[1-7]), and receptors (types 1 and 2 Ang II receptors, Mas receptor). Our goal is to ensure appropriate research methodology for investigations of the RAS in patients with severe acute respiratory syndrome coronavirus 2 and COVID-19 to ensure optimal rigor and reproducibility and appropriate interpretation of results from these investigations.
