ABSTRACT

BACKGROUND: People with kidney failure require renal replacement therapy in the form of dialysis or a kidney transplant for survival. Many facets of their life, both within and outside the dialysis unit, are impacted by the management of this disease. It is important to comprehend the experiences of people undergoing hemodialysis in order to improve the care provided to them. Therefore, this study aimed to explore the experiences of patients undergoing maintenance hemodialysis in Ethiopia. METHODS: A qualitative descriptive study was conducted at two healthcare facilities in Ethiopia. Individual interviews with 15 participants (men and women aged 19-63), undergoing hemodialysis in Ethiopia, were analyzed using reflexive thematic analysis. RESULTS: The analysis resulted in five themes: Feeling grateful, Facing a restricted life, a Supportive environment, Dreaming of a transplant, and Leading a hassled life. The subthemes include Trust in treatment, Faith in God, Challenging fluid and dietary restrictions, Being too fatigued to socialize, Being stigmatized, Family and social support, Supportive healthcare, Lacking a donor and sponsor, COVID-19 as a barrier, Financial constraints, Inaccessibility to care and transport and Access line implantation. Despite being dependent on a machine and having to deal with food and fluid restrictions as well as financial challenges, participants were hopeful and dreamed of a transplant. CONCLUSION: From the study's participants, it was discovered that the experiences of people with kidney failure undergoing hemodialysis were generally, considerably negative narratives. Based on the results we recommend development of multidisciplinary teams to better meet patients' physical, emotional, and social needs while undergoing hemodialysis. Such a team should also involve the patient's family members when caring for patients on hemodialysis.

ABSTRACT

BACKGROUND: A significant decrease in antibody titres several months after COVID-19 primary vaccination in end-stage kidney disease (ESKD) patients receiving maintenance haemodialysis has recently been reported. The waning in antibody titres has led to the recommendations for a booster dose to increase the antibody titres after vaccination. Consequently, it is crucial to analyse the long-term humoral immune responses after COVID-19 primary vaccination and assess the immunogenicity and safety of booster doses in haemodialysis (HD) patients. METHODS: Patients on maintenance haemodialysis who received the primary vaccine of CoronaVac (Sinovac) vaccine were administered with BNT162b2 (Pfizer-BioNTech) as the booster dose. The immunogenicity was assessed before (V1), one month (V2) and eight months (V3) after the primary vaccination, as well as one month after the booster dose (V4). Patients were followed up one month after the booster dose to assess the adverse events (AEs). RESULTS: The geometric mean titre (GMT) of anti-SARS-CoV-2 S-RBD IgG antibody at 8 months after the primary vaccination increased significantly to 5,296.63 (95%CI: 2,930.89-9,571.94) U/mL (p = < 0.0001) compared to before the primary vaccination. The GMT also increased significantly to 19,142.56 (95% CI: 13,489.63-27,227.01) U/mL (p < 0.0001) 1 month after the booster vaccine. Meanwhile, the median inhibition rate of neutralizing antibodies (NAbs) at 8 months after the primary vaccine and 1 month after the booster dose were not significantly different (p > 0.9999). The most common AEs after the booster dose included mild pain at the injection site (55.26%), mild fatigue (10.53%), and swelling at the injection site (10.53%). No serious AEs were reported. CONCLUSIONS: The majority of ESKD patients on haemodialysis mounted a good antibody response to the BNT162b2 booster vaccination with tolerable adverse events.

ABSTRACT

Treatment adherence (TA) is a critical issue and is under-investigated in hemodialysis patients. A multi-center study was conducted from July 2020 to March 2021 on 972 hemodialysis patients in eight hospitals in Vietnam to explore the factors associated with TA during the COVID-19 pandemic. Data were collected, including socio-demographics, an End-Stage Renal Disease Adherence Questionnaire (ESRD-AQ), 12-item short-form health literacy questionnaire (HLS-SF12), 4-item digital healthy diet literacy scale (DDL), 10-item hemodialysis dietary knowledge scale (HDK), 7-item fear of COVID-19 scale (FCoV-19S), and suspected COVID-19 symptoms (S-COVID19-S). Bivariate and multivariate linear regression models were used to explore the associations. Higher DDL scores were associated with higher TA scores (regression coefficient, B, 1.35; 95% confidence interval, 95%CI, 0.59, 2.12; p = 0.001). Higher FCoV-19S scores were associated with lower TA scores (B, -1.78; 95%CI, -3.33, -0.24; p = 0.023). In addition, patients aged 60-85 (B, 24.85; 95%CI, 6.61, 43.11; p = 0.008) with "very or fairly easy" medication payment ability (B, 27.92; 95%CI, 5.89, 44.95; p = 0.013) had higher TA scores. Patients who underwent hemodialysis for ≥5 years had a lower TA score than those who received <5 years of hemodialysis (B, -52.87; 95%CI, -70.46, -35.28; p < 0.001). These findings suggested that DDL and FCoV-19S, among other factors, should be considered in future interventions to improve TA in hemodialysis patients.

ABSTRACT

Objectives To project the prevalence of people receiving dialysis in Australia for 2021-30 to inform service planning and health policy. Methods Estimates were based on data from 2011 to 2020 from the Australia & New Zealand Dialysis & Transplant (ANZDATA) Registry and the Australian Bureau of Statistics. We projected dialysis and functioning kidney transplant recipient populations for the years 2021-30. Discrete-time, non-homogenous Markov models were built on probabilities for transition between three mutually exclusive states (Dialysis, Functioning Transplant, Death), for five age groups. Two scenarios were employed - stable transplant rate vs a continued increase - to assess the impact of these scenarios on the projected prevalences. Results Models projected a 22.5-30.4% growth in the dialysis population from 14 554 in 2020 to 17 829 ('transplant growth') - 18 973 ('transplant stable') by 2030. An additional 4983-6484 kidney transplant recipients were also projected by 2030. Dialysis incidence per population increased and dialysis prevalence growth exceeded population ageing in 40-59 and 60-69 year age groups. The greatest dialysis prevalence growth was seen among those aged ≥70 years. Conclusion Modelling of the future prevalence of dialysis use highlights the increasing demand on services expected overall and especially by people aged ≥70 years. Appropriate funding and healthcare planning must meet this demand.

ABSTRACT

BACKGROUND: Prolonged symptoms after corona virus disease 2019 (Long-COVID) in dialysis-dependent patients and kidney transplant (KT) recipients are important as a possible risk factor for organ dysfunctions, especially gastrointestinal (GI) problems, during immunosuppressive therapy. AIM: To identify the characteristics of GI manifestations of Long-COVID in patients with dialysis-dependent or KT status. METHODS: This observational, prospective study included patients with COVID-19 infection, confirmed by reverse transcription polymerase chain reaction, with the onset of symptoms between 1 January 2022 and 31 July 2022 which was explored at 3 mo after the onset, either through the out-patient follow-up or by telephone interviews. RESULTS: The 645 eligible participants consisted of 588 cases with hemodialysis (HD), 38 patients with peritoneal dialysis (PD), and 19 KT recipients who were hospitalized with COVID-19 infection during the observation. Of these, 577 (89.5%) cases agreed to the interviews, while 64 (10.9%) patients with HD and 4 (10.5%) cases of PD were excluded. The mean age was 52 ± 11 years with 52% women. The median dialysis duration was 7 ± 3 and 5 ± 1 years for HD and PD groups, respectively, and the median time post-transplantation was 6 ± 2 years. Long-COVID was identified in 293/524 (56%) and 21/34 (62%) in HD and PD, respectively, and 7/19 (37%) KT recipients. Fatigue was the most prevalent (96%) of the non-GI tract symptoms, whereas anorexia (90.9%), loss of taste (64.4%), and abdominal pain (62.5%) were the first three common GI manifestations of Long-COVID. Notably, there were 6 cases of mesenteric panniculitis from 19 patients with GI symptoms in the KT group. CONCLUSION: Different from patients with non-chronic kidney disease, there was a high prevalence of GI manifestations of Long-COVID in dialysis-dependent patients and KT recipients. An appropriate long-term follow-up in these vulnerable populations after COVID-19 infection is possibly necessary.

ABSTRACT

Hyperphosphatemia is a secondary disorder of chronic kidney disease that causes vascular calcifications and bone-mineral disorders. As per the US Centers for Disease Control and Prevention, renal damage requires first-priority medical attention for patients with COVID-19; according to a Johns Hopkins Medicine report, SARS-CoV-2 can cause renal damage. Therefore, addressing the research inputs required to manage hyperphosphatemia is currently in great demand. This review highlights research inputs, such as defects in the diagnosis of hyperphosphatemia, flaws in understanding the mechanisms associated with understudied tertiary toxicities, less cited adverse effects of phosphate binders that question their use in the market, socioeconomic challenges of renal treatment and public awareness regarding the management of a phosphate-controlled diet, novel biological approaches (synbiotics) to prevent hyperphosphatemia as safer strategies with potential additional health benefits, and future functional food formulations to enhance the quality of life. We have not only introduced our contributions to emphasise the hidden aspects and research gaps in comprehending hyperphosphatemia but also suggested new research areas to strengthen approaches to prevent hyperphosphatemia in the near future.

ABSTRACT

BACKGROUND: There is a paucity of data regarding the consequences of coronavirus disease 2019 (COVID-19) infection in patients with maintenance hemodialysis (MHD). Our objective was to identify the clinical manifestations and prognostic factors and to assess the impact of treatment schemes on the outcomeMaterials and methods: Here we present retrospectively collected data from medical records of patients on MHD hospitalized with COVID-19 infection from 1st June to 30th November 2020Result: Around 69 patients were admitted with a median age of 51 years. About 81% had hypertension, 41% had diabetes, and 24% had body mass index (BMI) ≥ 23 kg/m2 . Of all who died, 73.33% had dialysis vintage of <12 months (p = 0.06). Common presenting symptoms were fatigue (67%), fever (58%), cough (42%), and dyspnea (35%). Milder, severe, and critical disease was found in 35, 45, and 20% of patients, respectively. About 54 patients were living 4 weeks after discharge. Around 15 patients died, that includes all who received invasive ventilatory support. Nonsurvivors were older and had lower oxygen saturation on admission, lower hemoglobin (Hb), and worst lactate dehydrogenase (LDH), interleukin (IL)-6, and D-dimer values than survivors, which were statistically significant. Use of remdesivir and anticoagulant improves chances of survival (p-value 0.035 and 0.034, respectively) Conclusion: About one-third of patients had mild disease. Those with critical disease displayed high mortality. Older age, male gender, short dialysis vintage, lower oxygen saturation on admission, anemia, leucocytosis, higher inflammatory markers [except C-reactive protein (CRP)], bilateral lung opacity, and requirement of the mechanical ventilator are poor prognostic factors. CRP, ferritin, and lymphopenia are not good prognostic markers unlike in the general population. These findings need to be verified in larger cohorts.

ABSTRACT

BACKGROUND: Symptom networks can provide empirical evidence for the development of personalized and precise symptom management strategies. However, few studies have established networks of symptoms experienced by older patients on maintenance hemodialysis. Our goal was to examine the type of symptom clusters of older maintenance hemodialysis patients during dialysis and construct a symptom network to understand the symptom characteristics of this population. METHODS: The modified Dialysis Symptom Index was used for a cross-sectional survey. Network analysis was used to analyze the symptom network and node characteristics, and factor analysis was used to examine symptom clusters. RESULTS: A total of 167 participants were included in this study. The participants included 111 men and 56 women with a mean age of 70.05 ± 7.40. The symptom burdens with the highest scores were dry skin, dry mouth, itching, and trouble staying asleep. Five symptom clusters were obtained from exploratory factor analysis, of which the clusters with the most severe symptom burdens were the gastrointestinal discomfort symptom cluster, sleep disorder symptom cluster, skin discomfort symptom cluster, and mood symptom cluster. Based on centrality markers, it could be seen that feeling nervous and trouble staying asleep had the highest strength, and feeling nervous and feeling irritable had the highest closeness and betweenness. CONCLUSIONS: Hemodialysis patients have a severe symptom burden and multiple symptom clusters. Dry skin, itching, and dry mouth are sentinel symptoms in the network model; feeling nervous and trouble staying asleep are core symptoms of patients; feeling nervous and feeling irritable are bridge symptoms in this symptom network model. Clinical staff can formulate precise and efficient symptom management protocols for patients by using the synergistic effects of symptoms in the symptom clusters based on sentinel symptoms, core symptoms, and bridge symptoms.

ABSTRACT

Background: Since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, patients with chronic kidney disease vulnerable to suffering more severe COVID-19 disease and worse outcomes have been identified. Objectives: Our study's aim was to determine the incidence, characteristics, and outcomes of SARS-CoV-2 infection in patients of hemodialysis (HD) units in Mexico and to describe the availability of confirmatory testing. Methods: This study was multicentric study of 19 HD units, conducted between March 2020 and March 2021. Results: From a total of 5779 patients, 955 (16.5%) cases of suspicious COVID-19 were detected; a SARS-CoV-2 reverse transcription polymerase chain reaction test was done in only 50.6% of patients. Forty-five percentages were hospitalized and 6% required invasive mechanical ventilation (IMV). There was no significant difference in mortality between confirmed (131/483) and suspicious (124/472) cases (p = 0.74). The percentage of patients in need of hospitalization, IMV, and deceased was greater than in the rest of the study population. Conclusions: The study revealed that 49.4% of the cases were not confirmed, a worrisome observation given that this is a highly vulnerable population (higher probability of contagion and worse outcomes), in which 100% of patients should have a confirmatory test.

ABSTRACT

BACKGROUND: Molnupiravir is an essential oral antiviral agent against coronavirus disease 2019 (COVID-19); however, its real-world effectiveness has not been evaluated in patients undergoing haemodialysis (HD). METHODS: This multi-centre retrospective study, involving 225 patients undergoing HD with initially mild or asymptomatic COVID-19, was conducted to compare the risks of 30-day COVID-19-related acute care visits between patients receiving and not receiving molnupiravir. Patients who received molnupiravir were stratified by rapid antigen detection (RAD) test results on day 7 after disease onset to assess whether rapid molnupiravir introduction accelerated viral clearance. RESULTS: Thirty-day COVID-19-related acute care visits were reported in 9.41% and 21.74% of the molnupiravir and control groups, respectively, and use of molnupiravir markedly reduced the risk of acute care visits after adjusting for baseline characteristics via propensity score weighting [hazard ratio 0.218, 95% confidence interval (CI) 0.074-0.642; P=0.006]. The tolerability of molnupiravir in the enrolled patients was generally acceptable, with only 11.88% of molnupiravir users reporting mild adverse events. Moreover, rapid initiation of molnupiravir within 1 day of COVID-19 onset was an independent predictor of conversion to a negative RAD test result on day 7 after disease onset (odds ratio 6.207, 95% CI 2.509-15.358; P<0.001). CONCLUSIONS: Molnupiravir is well tolerated and decreases the medical needs in patients with COVID-19 undergoing HD. Furthermore, the rapid initiation of molnupiravir accelerates viral clearance in patients with COVID-19 undergoing HD. These findings highlight the therapeutic role of molnupiravir for this vulnerable population.

ABSTRACT

OBJECTIVE: To describe the experiences of nephrologists on caring for patients undergoing in-centre haemodialysis during the COVID-19 pandemic in Latin America. DESIGN: Twenty-five semistructured interviews were conducted by Zoom videoconference in English and Spanish languages during 2020 until data saturation. Using thematic analysis, we conducted line-by-line coding to inductively identify themes. SETTING: 25 centres across nine countries in Latin America. PARTICIPANTS: Nephrologists (17 male and 8 female) were purposively sampled to include diverse demographic characteristics and clinical experience. RESULTS: We identified five themes: shock and immediate mobilisation for preparedness (overwhelmed and distressed, expanding responsibilities to manage COVID-19 infection and united for workforce resilience); personal vulnerability (being infected with COVID-19 and fear of transmitting COVID-19 to family); infrastructural susceptibility of dialysis units (lacking resources and facilities for quarantine, struggling to prevent cross-contamination, and depletion of personal protective equipment and cleaning supplies); helplessness and moral distress (being forced to ration life-sustaining equipment and care, being concerned about delayed and shortened dialysis sessions, patient hesitancy to attend to dialysis sessions, being grieved by socioeconomic disparities, deterioration of patients with COVID-19, harms of isolation and inability to provide kidney replacement therapy); and fostering innovative delivery of care (expanding use of telehealth, increasing uptake of PD and shifting focus on preventing syndemics). CONCLUSION: Nephrologists felt personally and professionally vulnerable and reported feeling helpless and morally distressed because they doubted their capacity to provide safe care for patients undergoing dialysis. Better availability and mobilisation of resources and capacities to adapt models of care, including telehealth and home-based dialysis, are urgently needed.

ABSTRACT

PURPOSE OF REVIEW: The novel coronavirus 2019 (COVID-19) pandemic has upended maintenance dialysis in the United States. I review changes in prevalence, incidence, mortality, and other clinical outcomes among patients undergoing dialysis since March 2020, highlighting vulnerabilities in the current system and opportunities for improved care in the future. RECENT FINDINGS: The number of dialysis patients in the United States declined between March 2020 and March 2021, an unprecedented year-over-year drop in the census. Some of the decline can be attributed to an early drop in patients initiating dialysis but most of the decline can be attributed to excess mortality. Kidney transplants also declined during the early part of the pandemic. Home dialysis utilization increased during 2020 but that increase was largely in line with secular trends. The rate of hospitalization for causes other than COVID-19 fell significantly during 2020. SUMMARY: The epidemiology of dialysis in the United States is clearly modifiable, as it reflects decisions to initiate treatment, prescribe home therapies, and hospitalize patients with acute medical needs. On the other hand, some outcomes are powerfully guided by health outcomes in the general population, thus limiting the ability of dialysis providers and nephrologists to influence outcomes.

ABSTRACT

Background: The global burden of persistent COVID-19 in hemodialysis (HD) patients is a worrisome scenario worth of investigation for the critical care of chronic kidney disease (CKD). We performed an exploratory post-hoc study from the trial U1111-1237-8231 with two specific aims: i) to investigate the prevalence of COVID-19 infection and long COVID symptoms from our Cohort of 178 Brazilians HD patients. ii) to identify whether baseline characteristics should predict long COVID in this sample. Methods: 247 community-dwelling older (>60 years) patients (Men and women) undergoing HD (glomerular filtration rate < 15 mL/min/1.73m2) with arteriovenous fistula volunteered for this study. All patients presented hypertension and diabetes. Patients were divided in two groups: without long-COVID and with long-COVID. Body composition, handgrip strength, functional performance, iron metabolism, phosphate, and inflammatory profile were assessed. Patients were screened for 11-months after COVID-19 infection. Results were considered significant at P < 0.05. Results: We found that more than 85% of the COVID-19 infected patients presented a severe condition during the infection. In our sample, the mortality rate over 11-month follow was relatively low (8.4%) when compared to worldwide (approximately 36%). Long COVID was highly prevalent in COVID-19 survivors representing more than 80% of all cases. Phosphate and IL-10 were higher in the long COVID group, but only phosphate higher than 5.35 mg/dL appears to present an increased prevalence of long COVID, dyspnea, and fatigue. Conclusion: There was a high prevalence of COVID-19 infection and long COVID in HD patients from the Brazilian trial 'U1111-1237-8231'. HD clinics should be aware with phosphate range in HD patients as a possible target for adverse post-COVID events.

ABSTRACT

Patients with Chronic Kidney Disease are among those individuals at increased risk for developing more serious forms of Covid-19. This increased risk starts in the pre-dialysis phase of the disease. Providing useful information for these patients, in language that facilitates the understanding of the disease, can help nephrologists and other healthcare professionals to establish a more effective communication with these patients and help minimize contagion and the risks of serious illness in this population.

ABSTRACT

Background: The response to vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) varies depending on comorbidities. This study evaluated the clinical and immunological factors affecting the humoral response of patients with end-stage renal disease (ESRD) to the BNT162b2 vaccine. Methods: Humoral immunity was evaluated in 54 ESRD patients using serum levels of anti-receptor-binding domain (RBD) and neutralizing antibodies (NAbs), measured by a chemiluminescent immunoassay 30 (T1), 60 (T2), and 120 (T3) days after the second vaccine dose. The results were correlated to baseline patient T- and B-lymphocyte subpopulations determined by flow cytometry. Results: The proportion of seroconverted patients based on the NAb titer decreased from 83.3% at T1 to 53.7% at T3. Age was negatively correlated to the NAb titer at T1 and T2. Patients receiving hemodiafiltration had higher NAb titers at T3. Diabetes was associated with a lower response rate at T3. Univariate analysis revealed a positive correlation between the naïve CD4 T-lymphocyte population and RBD titer at T1 and the NAb titer at T3, with no association observed with naïve CD8 T lymphocytes. NAb titers at T3 were significantly correlated with late-differentiated CD4 T lymphocytes and terminally differentiated effector memory cells re-expressing CD45RA (TEMRA) CD8 T lymphocytes. RBD levels were positively correlated with naïve and memory B-lymphocyte counts at T3. Conclusions: Age, diabetes, and hemodialysis prescription had significant impacts on the response to vaccination. T- and B-lymphocyte phenotypes are major determinants of the humoral response potency to SARS-CoV-2 vaccination with BNT162b2 in patients with ESRD.

ABSTRACT

BACKGROUND: In 2020, Lebanon has witnessed its worst economic crisis, exacerbated by the COVID-19 pandemic and a massive explosion of its capital. Amidst these stressors, this study aims at assessing the prevalence of depression, anxiety, suicidality, post-traumatic stress disorder (PTSD) and cognitive impairment in patients undergoing hemodialysis in an academic hospital destroyed by the explosion. METHODS: This cross-sectional study conducted 6 months after the blast included adults on hemodialysis, with no previous diagnoses of dementia or intellectual disability. It explores prevalence rates of psychiatric disorders, in addition to other medical and psychosocial variables such as frailty, malnutrition, sarcopenia, quality of life and religiosity. RESULTS: Forty two patients (mean age 66.1; SD: 11.2 years) undergoing hemodialysis for 6.12 years (SD:7.22 years) were included. Anxiety and depression rates reached 54.8% and 57.1% using cut-offs of 6 and 7 respectively on the Hospital Anxiety and Depression rating Scale. 9.5% of the patients reported being in the hospital at the time of the blast and 7.1% reported being injured. 33.3% screened positively for PTSD using a cut-off of 23 on the PCL-5. 26.2% had passive death wishes and 7.1% had suicide plans, however no one had attempted it. 23.8% were found cognitively impaired as shown by the Mini-Cog (<3). Around two-third of participants were moderately to severely malnourished per the GLIM criteria. One third suffered from frailty, according to the FRAIL screening tool. Around 60% suffered from sarcopenia, based on handgrip strength measures. These findings contrast with "acceptable to good" quality of life subjectively reported by participants on the Short Form 36 (SF-36) Health Survey. While one-third of participants participated in organizational religious activities, 88% reported significant subjective meaning of religion in their heart. CONCLUSIONS: Rates of depression, anxiety, PTSD, suicidality, and cognitive impairment were found to be alarming in the setting of an urban dialysis unit following a major explosion. Psychiatric disorders were found to be compounded with increased prevalence of malnutrition, frailty, and sarcopenia. These findings urge healthcare providers to implement early diagnostic and intervention strategies to improve both mental and physical wellbeing of this vulnerable population, in similar settings.

ABSTRACT

BACKGROUND: Immunocompromised patients have been at an increased risk of succumbing to coronavirus disease 2019 (COVID-19) since the beginning of the pandemic. METHODS: Here, we analyzed mortality and case fatality data from dialysis and kidney transplant patients, and compared each with an age-matched subgroup of the general population. RESULTS: We found that both patients on dialysis and kidney transplant patients remain at increased risk of succumbing to COVID-19 despite all available countermeasures. CONCLUSIONS: The analyses underline the need for additional protection for this vulnerable population.
