ABSTRACT
Objective. To study the course of the new coronavirus infection in patients with chronic kidney disease (CKD), to identify cases of acute kidney injury (AKI) in the setting of COVID-19 infection, and to access the impact of renal function on prognosis in these categories of patients during the acute phase and after hospitalization, at 3, 6, and 12 months after recovery. Materials and methods. The ACTIV and ACTIV 2 registries included men and women older than 18 years with a diagnosis of COVID-19 based on a positive PCR test for COVID-19 and a characteristic chest X-ray or computed tomography chest scan. Results. A total of 9364 patients (4404 men, average age59 [48-69]) were included in the analysis. 716 (7.67 %) patients had CKD. 8496 (90,7 %) patients had their glomerular filtration rate (GFR) measured during hospitalization, and the values were distributed as follows: >=90 ml/min/1.73m2 - in 4289 (50,5 %) patients, 89-60 ml/min/1.73m2 - in 3150 (37,1 %) patients, 59-45 ml/min/1.73m2 - in 613 (7,22 %), 44-30 ml/min/1.73m2 - in 253 (2,98 %), 29-15 ml/min/1.73m2 - in 110 (1,29 %), <15 ml/min/1.73m2 - in 81 (0,95 %) patients. 11.6 % of the subjects (n=1068) developed AKI during hospitalization. This complication was reported more often than cytokine storm (in 7.46 % in 687 patients, p<0,001) or sepsis (in 0.17 % in 16 patients, p=620). CKD increased the risk of death by 3.94-fold in patients with COVID-19 during hospitalization compared with patients without CKD. The mortality of patients with AKI during hospitalization was 3.94 times higher than the mortality of those without AKI. CKD also affected long-term survival after hospitalization: within 3 months of follow-up, the risk of death in patients with CKD increased 4.88-fold, within 6 months - 4.24-fold, after 12 months - 8.36-fold. Conclusion. The prevalence of CKD in COVID-19 patients is similar to that in the general population. AKI developed in 11.6 % of cases with COVID-19 infection and was observed more frequently in patients with overweight and hyperglycemia. CKD and AKI increased the risk of hospital mortality in patients with COVID-19. In the group of patients with CKD, mortality increased in the post-COVID period, 3, 6 and 12 months after. The high mortality rate of patients who had AKI during the coronavirus infection was observed only in the first 3 months of follow-up in the post-COVID period.Copyright © 2023 The authors.
ABSTRACT
COVID-19 is a serious infection that cause severe injuries and deaths worldwide. The COVID-19 virus can infect people of all ages, especially the elderly. Furthermore, elderly who have co-morbid conditions (e.g., chronic conditions) are at an increased risk of death. At the present time, no approach exists that can facilitate the characterization of patterns of COVID-19 death. In this study, an approach to identify patterns of COVID-19 death efficiently and systematically is applied by adapting the Apriori algorithm. Validation and evaluation of the proposed approach are based on a robust and reliable dataset collected from Health Affairs in the Makkah region of Saudi Arabia. The study results show that there are strong associations between hypertension, diabetes, cardiovascular disease, and kidney disease and death among COVID-19 deceased patients © 2023, International Journal of Advanced Computer Science and Applications.All Rights Reserved.
ABSTRACT
Objective To explore the sociodemographic and psychological factors influencing the continuity of treatment of patients with chronic kidney disease under the regular epidemic prevention and control of coronavirus disease 2019 (COVID-19). Methods A total of 277 patients with chronic kidney disease who were admitted to Department of Nephrology, The First Affiliated Hospital of Naval Medical University (Second Military Medical University) from Apr. 2020 to Mar. 2021 were enrolled and divided into 3 groups: non-dialysis group (n=102), hemodialysis (HD) group (n=108), and peritoneal dialysis (PD) group (n=67). All patients were investigated by online and offline questionnaires, including self-designed basic situation questionnaire, self-rating anxiety scale (SAS), and self-rating depression scale (SDS). The general sociodemographic data, anxiety and depression of the 3 groups were compared, and the influence of sociodemographic and psychological factors on the interruption or delay of treatment was analyzed by binary logistic regression model. Results There were significant differences in age distribution, marital status, occupation, medical insurance type, caregiver type, whether there was an urgent need for hospitalization and whether treatment was delayed or interrupted among the 3 groups (all P<0.05). The average SAS score of 65 PD patients was 38.15+/-15.83, including 53 (81.5%) patients without anxiety, 7 (10.8%) patients with mild anxiety, and 5 (7.7%) patients with moderate to severe anxiety. The average SAS score of 104 patients in the HD group was 36.86+/-14.03, including 81 (77.9%) patients without anxiety, 18 (17.3%) patients with mild anxiety, and 5 (4.8%) patients with moderate to severe anxiety. There were no significant differences in the mean score of SAS or anxiety severity grading between the 2 groups (both P>0.05). The mean SDS scores of 65 PD patients were 53.42+/-13.30, including 22 (33.8%) patients without depression, 21 (32.3%) patients with mild depression, and 22 (33.8%) patients with moderate to severe depression. The mean SDS scores of 104 patients in the HD group were 50.79+/-10.76, including 36 (34.6%) patients without depression, 56 (53.8%) patients with mild depression, and 12 (11.6%) patients with moderate to severe depression. There were no significant differences in mean SDS scores or depression severity grading between the 2 groups (both P>0.05). The results of intra-group comparison showed that the incidence and severity of depression were higher than those of anxiety in both groups. Multivariate binary logistic regression analysis showed that high school education level (odds ratio [OR]=5.618, 95% confidence interval [CI]) 2.136-14.776, P<0.01), and unmarried (OR=6.916, 95% CI 1.441-33.185, P=0.016), divorced (OR= 5.588, 95% CI 1.442-21.664, P=0.013), urgent need for hospitalization (OR=8.655, 95% CI 3.847-19.476, P<0.01) could positively promote the continuity of treatment in maintenance dialysis patients under the regular epidemic prevention and control of COVID-19. In the non-dialysis group, no sociodemographic and psychological factors were found to be associated with the interruption or delay of treatment (P>0.05). Conclusion Education, marital status, and urgent need for hospitalization are correlated with the continuity of treatment in patients with chronic kidney disease on maintenance dialysis.Copyright © 2022, Second Military Medical University Press.

ABSTRACT
Objectives: The use of glucocorticoids (GC) has been associated with increased risk of hospitalization for coronavirus infection and reduced immunogenicity of SARS-CoV-2 vaccines in immune-mediated diseases (IMD) patients. However, there is still controversy of which dose of GC is correlated with impaired vaccine response on each of the diverse COVID-19 vaccines available, as well as the possible influence of other concurrent immunosuppressants. This study aimed at evaluating the effect of GC on serological response after two doses of BNT162b2 (Pfizer/BioNTech), CoronaVac (inactivated SARS-CoV-2 Vaccine) and ChadOx1 (AstraZeneca) and after the booster dose in patients with IMD. Method(s): The data were extracted from a multicenter longitudinal observational Brazilian cohort (SAFER: Safety and Efficacy on COVID19 Vaccine in Rheumatic Disease). Patients >18 years of age with IMD were evaluated after 2 doses of the same vaccine against COVID-19 and after a booster vaccine, applied according to Brazilian National Immunization Program. All patients underwent clinical examination and collected blood samples for immunogenicity tests. Serological response was evaluated by Anti-RBD titers (IgG) at baseline and 4 weeks after each vaccine dose. Result(s): Among the 1009 patients evaluated, 301 were using GC (196/401 SLE, 52/199 RA and 27/74 vasculitis). Patients using GC were younger (38.2 vs 40,8 years, p = 0,002), had higherBMI (27,6 vs 26,4 p = 0,008), higher prevalence of kidney disease (3,3% vs 0,5%, p = 0,001) and of thrombosis (11,6% vs 5,9%, p = 0,002) than non-users. Regarding the type of vaccine, most of the GC users received CoronaVac (61.7%), while only 31.9%of non-users received this vaccine (p alpha 0.001). Although there were similar rates of pre-vaccination infections among them, patients with GC tended to have a higher incidence of confirmed COVID-19 infection after the 2nd dose of the vaccine compared to non-users (4.5% vs 2.0% p = 0.054). The antibody titers after the 1st dose of COVID-19 vaccines were similar between groups, but there was a worse response in the GC group after the 2nd dose (p = 0.039). However, this difference was not statistically significant after the 3rd dose (Figure). Conclusion(s): GC use may compromise vaccine-induced immunogenicity after a 2-dose regimen;however, this effect does not remain significant after the booster dose. Multivariate analysis is still pending to assess the potential difference in the impact of GC on the immune response depending on GC dose, type of vaccine and associated drugs.
ABSTRACT
Intro: During the pandemic of COVD-19, several vaccines have been developed and are currently used worldwide. However, head-to-head studies comparing various vaccines are limited. Therefore, This single-center, prospective, realworld study. head-to-head study of compared the effectiveness of BNT162b2 (Pfizer BioNTech), mRNA-1273 (Moderna) ChAdOx1-S (Astra Zeneca) vaccines. The kinetics of SARS-CoV2 spike antibodies were monitored post-vaccination and following two booster doses in COVID-19 naive and previously infected adults. Method(s): The primary outcome was the emergence of virologically positive COVID-19 cases after vaccine completion. The secondary outcome was the occurrence of postvaccination COVID-19-related hospitalizations. The titers of anti-SARS-CoV-2 IgG antibodies against the S1 subunit of the virus's spike protein were measured after the first and second doses of the three vaccines and the booster doses. Finding(s): The current study enrolled and followed 1550 participants who received ChAdOx1-S or BNT162b2, or mRNA-1273, and 1550 non-vaccinated subjects between March 2021 and February 2022. After completing two vaccine doses, the effectiveness in preventing COVID-19 cases was 89.2%, 95.5%, and 94.6% for ChAdOx1-S or BNT162b2, or mRNA-1273, respectively. Four COVID-19-related hospitalizations (0.26%) were reported in the vaccinated versus 648 (41.81%) non-vaccinated participants (P<0.0001). Following the Pfizer booster dose, no COVID-19-positive cases or hospitalizations were reported. In the three vaccines, SARS-CoV2 antibody titers increased gradually after the first dose, peaked 3-4 weeks after the second dose, then declined after 28-32 weeks. Enhanced antibody response was observed after the booster dose and was maintained until the end of follow-up. Comorbidities were associated with lower antibody titers, particularly diabetes, autoimmune diseases, and advanced renal diseases. Conclusion(s): The study showed that the three COVID-10 vaccines effectively reduced the risk of virologically confirmed COVID-19 disease and prevented severe illness and hospitalizations in COVID-19 naiive and previously infected. Booster doses enhance the SARS-CoV2 antibody response and decrease the incidence of virologically proven severe COVID-19.Copyright © 2023
ABSTRACT
Interleukin-6 (IL-6) plays a key role in the pathogenesis of COVID-19, which determines the indications for the therapeutic use of its antagonists. However, data on their effectiveness and optimal timing of appointment are contradictory. The question of the possibility of their use in patients with impaired kidney function has not been studied. The aim of the study is to evaluate the efficacy and safety of the use of monoclonal antibodies to IL-6 receptors in COVID-19 in patients with chronic kidney disease (CKD) of stages 2-5 (predialysis) who do not need renal replacement therapy. Material and methods. A clinical retrospective uncontrolled single-center study included 45 patients (60% of men) with CKD stages 2-5 aged 22-95 years (median - 58 years) hospitalized with predominantly severe uncritical COVID-19 infection. Treatment of COVID-19 was carried out in accordance with the Interim guidelines for the prevention and treatment of new coronavirus infection of the Ministry of Health of Russian Federation. Results. The majority of patients (n=36;73.3%) had CKD stage 3b-5, CKD stage 2 was in 7 (15.5%) and stage 3a - in 5 (11.1%) patients. The median serum creatinine level (Cr) was 164 [131;292] mumol/l, glomerular filtration rate (GFR) was 30 [13;49] ml/min/1.73 m2, CRP 67.5 [37.2;106.75] mg/l. The introduction of monoclonal antibody to IL-6 receptors led to a decrease in the activity of the infectious process (CRP 1.55 [0.33;4.15] mg/l, p<0.001), regression of pneumonia, which did not require mechanical ventilation and hospitalization in the intensive care unit. According to the decision of the medical commission, patients were injected with monoclonal antibodies to IL-6 receptors: tocilizumab (n=36;80%), levilimab (n=2;4.4%), combined therapy with two drugs (n=7;15.5%). Therapy with IL-6 antagonists did not have a negative effect on kidney function. The levels of Cr decreased on average from 224.3+/-145.2 mmol/l at admission to 160+/-92.55 mmol/l at discharge (p<0.001), GFR increased from 32.6+/-20.9 ml/min/1.73 m2 at admission to 53+/-31.7 ml/min/1.73 m2 at discharge (p<0.001). In the majority of patients (n=36, 80%) GFR has risen, and only in 9 (20%) cases it remained approximately at the same low level. No serious adverse events have been reported with the use of IL-6 antagonists, as well as concomitant infectious complications. No deaths have been reported. The median length of stay in bed was 14 [10;19] days. Conclusion. The results of the study allow us to state that in patients with CKD, monoclonal antibodies to IL-6 receptors have a good safety profile and can be successfully used in moderate and severe forms of COVID-19, regardless of the state of kidney function.Copyright © 2022 by the authors.
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.

AIM: To evaluate the albuminuria-lowering effect of dapagliflozin, exenatide, and the combination of dapagliflozin and exenatide in patients with type 2 diabetes and microalbuminuria or macroalbuminuria. METHODS: Participants with type 2 diabetes, an estimated glomerular filtration rate (eGFR) of more than 30 ml/min/1.73m2 and an urinary albumin: creatinine ratio (UACR) of more than 3.5 mg/mmol and 100 mg/mmol or less completed three 6-week treatment periods, during which dapagliflozin 10 mg/d, exenatide 2 mg/wk and both drugs combined were given in random order. The primary outcome was the percentage change in UACR. Secondary outcomes included blood pressure, HbA1c, body weight, extracellular volume, fractional lithium excretion and renal haemodynamic variables as determined by magnetic resonance imaging. RESULTS: We enrolled 20 patients, who completed 53 treatment periods in total. Mean percentage change in UACR from baseline was -21.9% (95% CI: -34.8% to -6.4%) during dapagliflozin versus -7.7% (95% CI: -23.5% to 11.2%) during exenatide and -26.0% (95% CI: -38.4% to -11.0%) during dapagliflozin-exenatide treatment. No correlation was observed in albuminuria responses between the different treatments. Numerically greater reductions in systolic blood pressure, body weight and eGFR were observed during dapagliflozin-exenatide treatment compared with dapagliflozin or exenatide alone. Renal blood flow and effective renal plasma flow (ERPF) did not significantly change with either treatment regimen. However, all but four and two patients in the dapagliflozin and dapagliflozin-exenatide groups, respectively, showed reductions in ERPF. The filtration fraction did not change during treatment with dapagliflozin or exenatide, and decreased during dapagliflozin-exenatide treatment (-1.6% [95% CI: -3.2% to -0.01%]; P = .048). CONCLUSIONS: In participants with type 2 diabetes and albuminuria, treatment with dapagliflozin, exenatide and dapagliflozin-exenatide reduced albuminuria, with a numerically larger reduction in the combined dapagliflozin-exenatide treatment group.

This case report details a 43-year-old female diagnosed with the collapsing variant of focal segmental glomerulosclerosis (FSGS) post-infection with coronavirus disease 2019 (COVID-19). The patient contracted COVID-19 after returning from a trip to Florida and initially presented to the emergency department with gastrointestinal symptoms. Thereafter, the patient was diagnosed with COVID-19 and was admitted for acute kidney injury and worsening COVID-19 infection. FSGS is a glomerulopathy that consists of glomerular scarring that leads to nephrotic syndrome, secondary to podocyte effacement. FSGS has many causes, as well as distinct variants, but is noted to have an association with some viruses, most notably HIV and cytomegalovirus (CMV). Although the association between FSGS and HIV or CMV is well established, the evidence is minimal in regard to other viruses. This case report serves to highlight the potential association of COVID-19 with FSGS.
ABSTRACT
BACKGROUND: Diabetic kidney disease (DKD) increases the risk of cardiovascular (CV) complications, kidney disease progression, and mortality. We aimed to determine the incidence and risk of these outcomes according to DKD phenotype among the Jordanian population. METHODS: A total of 1172 type 2 diabetes mellitus patients with estimated glomerular filtration rates (eGFRs) of >30 ml/min/1.73 m2 were followed-up from 2019 to 2022. At baseline, patients were classified according to the presence of albuminuria (>30 mg/g creatinine) and reduced eGFR (<60 ml/min/1.73 m2) into four phenotypes: non-DKD (reference category), albuminuric DKD without decreased eGFR, non-albuminuric DKD with decreased eGFR, and albuminuric DKD with decreased eGFR. RESULTS: Mean follow-up was 2.9 ± 0.4 years. Overall, 147 patients (12.5 %) experienced CV events, while 61 (5.2 %) demonstrated kidney disease progression (eGFR: <30 ml/min/1.73 m2). The mortality rate was 4.0 %. Multivariable-adjusted risk for CV events and mortality was greatest for the albuminuric DKD with decreased eGFR group (hazard ratio [HR]: 1.45, 95 % confidence interval [CI]: 1.02-2.33 and HR: 6.36, 95 % CI: 2.98-13.59, respectively), with the risk increasing when adjusted for prior CV history (HR: 1.47, 95 % CI: 1.06-3.42 and HR: 6.70, 95 % CI: 2.70-16.60, respectively). Risk of a ≥40 % decline in eGFR was greatest for the albuminuric DKD with decreased eGFR group (HR: 3.45, 95 % CI: 1.74-6.85), followed by the albuminuric DKD without decreased eGFR group (HR: 1.6, 95 % CI: 1.06-2.75). CONCLUSION: Thus, patients with albuminuric DKD and decreased eGFR were at greater risk for poor CV, renal, and mortality outcomes compared to other phenotypes.

Despite the enormous global market of dietary supplements, the impact of dietary supplements on kidney disease is still unclear. Based on the National Health and Nutrition Examination Survey from 2015 to 2017, this study evaluated the association between dietary supplement and chronic kidney disease (CKD) in 13,271 Korean adults. Among the dietary supplements, vitamin and mineral intake was the highest at 61.41%, followed by omega-3 fatty acids at 11.85%, and ginseng at 7.99%. The prevalence of CKD was significantly higher in those who consumed amino acids and proteins, ginseng and red ginseng, and herbal medicine (plant extract)-berries than in those who did not. Conversely, patients who consumed probiotic supplements had a significantly lower prevalence of CKD than those who did not. In the population without CKD risk factors or history of CKD, the prevalence of CKD was high in the group consuming ginseng and red ginseng. After adjusting for covariates, the herbal medicine (plant extract)-berry group showed an independent association with CKD incidence. In conclusion, it is suggested that dietary supplements may affect kidney function. Further large-scale cohort studies are required to elucidate the exact effects of each dietary supplement on CKD.

High blood pressure (BP) and type-2 diabetes (T2DM) are forerunners of chronic kidney disease and left ventricular dysfunction. Home BP telemonitoring (HTM) and urinary peptidomic profiling (UPP) are technologies enabling risk stratification and personalized prevention. UPRIGHT-HTM (NCT04299529) is an investigator-initiated, multicenter, open-label, randomized trial with blinded endpoint evaluation designed to assess the efficacy of HTM plus UPP (experimental group) over HTM alone (control group) in guiding treatment in asymptomatic patients, aged 55-75 years, with ≥5 cardiovascular risk factors. From screening onwards, HTM data can be freely accessed by all patients and their caregivers; UPP results are communicated early during follow-up to patients and caregivers in the intervention group, but at trial closure in the control group. From May 2021 until January 2023, 235 patients were screened, of whom 53 were still progressing through the run-in period and 144 were randomized. Both groups had similar characteristics, including average age (62.0 years) and the proportions of African Blacks (81.9%), White Europeans (16.7%), women 56.2%, home (31.2%), and office (50.0%) hypertension, T2DM (36.4%), micro-albuminuria (29.4%), and ECG (9.7%) and echocardiographic (11.5%) left ventricular hypertrophy. Home and office BP were 128.8/79.2 mm Hg and 137.1/82.7 mm Hg, respectively, resulting in a prevalence of white-coat, masked and sustained hypertension of 40.3%, 11.1%, and 25.7%. HTM persisted after randomization (48 681 readings up to 15 January 2023). In conclusion, results predominantly from low-resource sub-Saharan centers proved the feasibility of this multi-ethnic trial. The COVID-19 pandemic caused delays and differential recruitment rates across centers.
