Abstract OBJECTIVES Chronic kidney disease (CKD) is prevalent in patients undergoing cardiovascular surgery, and it negatively impacts procedural outcomes; however, its influence on the outcomes of aortic surgery has not been well studied. This study aims to elucidate the importance of CKD on the outcomes of aortic root replacement (ARR). METHODS Patients who underwent ARR between 2005 and 2019 were retrospectively reviewed (n = 882). Patients were divided into 3 groups based on the Kidney Disease: Improving Global Outcomes criteria: Group 1 [estimated glomerular filtration rate (eGFR) ≥ 60 ml/min/1.73 m2, n = 421); Group 2 (eGFR = 30–59 ml/min/1.73 m2, n = 424); and Group 3 (eGFR < 30 ml/min/1.73 m2, n = 37). To reduce potential confounding, a propensity score matching was also performed between Group 1 and the combined group of Group 2 and Group 3. The primary end point was 10-year survival. Secondary end points were in-hospital mortality and perioperative morbidity. RESULTS Severe CKD patients presented with more advanced overall chronic and acute illnesses. Kaplan–Meier analysis showed a significant correlation between CKD stage and 10-year survival (log-rank P < 0.001). The number of events for Group 1 was 15, Group 2 was 49 and Group 3 was 11 in 10 years. Group 3 had significantly higher in-hospital mortality (13.5% vs 3.5% in Group 2 vs 0.7% in Group 1, P < 0.001) and stroke (8.1% vs 7.1% vs 1.2%, P < 0.001) as well as introduction to new dialysis (27.0% vs 5.4% vs 1.7%, P < 0.001). eGFR was shown to be an independent predictor of mortality (hazard ratio, 0.98; 95% confidence interval, 0.96–0.99). Comparison between propensity matched groups showed similar postoperative outcomes, and eGFR was still identified as a predictor of mortality (hazard ratio, 0.97; 95% confidence interval, 0.95–0.99). CONCLUSIONS Higher stage in CKD negatively impacts the long-term survival in patients who are undergoing ARR.

Purpose of the study. To examine the frequency and risk factors for the development of diastolic dysfunction (DD) of the left ventricle (LV) of the heart in patients with chronic kidney disease (CKD). Materials and methods. The study included 225 patients with stage I-CKD of non-diabetic etiology (median age 47.0 years, 50.2% of women). Depending on the degree of decrease in the glomerular filtration rate (GFR), all patients were divided into 3 groups. Group 1 (n=70) consisted of patients with GFR 89-45 ml / min / 1.73 m2, group 2 (n=120) - patients with GFR 44-15 ml / min / 1.73 m2, group 3 (n=35) - patients with GFR

Изменения минерального гомеостаза являются причиной костных нарушений зубочелюстной системы (ЗЧС) при хронической болезни почек (ХБП) у детей и могут развиваться задолго до появления клинических проявлений уремической токсинемии на 2-й стадии ХБП. В последние годы большое внимание уделяется неинвазивным методам диагностики патологии полости рта у детей. Наиболее известными индикаторами нарушения костного метаболизма считают матриксную металлопротеиназу 8 (ММР-8) и остеопротогерин (OPG). Цель исследования - установить закономерности изменения содержания ММР-8 и OPG в слюне детей с различной тяжестью ХБП. Объект и методы. Проведено исследование содержания ММР-8 и OPG в слюне у 76 детей, которые были разделены на равные группы по 19 человек: 1 группа - дети с ХБП 1-2 степени, получающие медикаментозное лечение; 2 группа - дети с терминальной стадией ХБП, получающие заместительную почечную терапию в объёме гемодиализа; 3 группа - дети через год после перенесённой трансплантации почки; 4 группа (группа сравнения) - дети с малой хирургической патологией, не имеющие патологии почек. Сбор слюны осуществлялся абсорбционным методом до медикаментозной коррекции основного заболевания утром до приема пищи. Исследование ММР-8 и OPG проводили методом твердофазного иммуноферментного анализа. Результаты. Установлено, что содержание ММР-8 и OPG в слюне у детей с различной степенью ХБП было значительно выше по отношению к группе сравнения. Максимальные значения ММР-8 регистрировались во 2-й группе у детей с терминальной ХБП, находящихся на гемодиализе. Повышение содержания OPG в слюне отмечалось в 1 группе детей с ХБП 1-2-й степени и 3-й группе пациентов, через год после перенесённой трансплантации почки. Заключение. Полученные результаты показывают возможность использования слюны в качестве биологической жидкости для диагностики доклинических этапов нарушения костного метаболизма у детей с ХБП, а ММР-8 и OPG в слюне могут рассматриваться в качестве предиктивных и прогностических маркеров. Changes in mineral homeostasis cause bone disorders of the dentition in children with chronic kidney disease (CKD) and may develop long before the onset of clinical manifestations of uremic toxemia in stage 2 CKD. In recent years, much attention has been paid to noninvasive methods for diagnosing oral pathology in children. The most common indicators of metabolic bone disorders are matrix metalloproteinase-8 (MMP-8) and osteoprotogerin (OPG). The aim of the study was to establish the patterns of changes in salivary concentrations of MMP-8 and OPG in children with various severity of CKD. Subject and methods. Salivary levels of MMP-8 and OPG were studied in 76 children divided into four equal groups: group 1, children with stage 1-2 CKD receiving a drug treatment; group 2, children with end-stage CKD receiving renal replacement therapy with hemodialysis; group 3, children one year after the kidney transplantation; and group 4 (comparison group), children with a minor surgical pathology without a kidney pathology. Saliva samples were collected by the absorption method before administration of drugs for the underlying disease, one hour before the morning meal. Salivary concentrations of MMP-8 and OPG were measured by enzyme-linked immunosorbent assay. Results. Salivary levels of MMP-8 and OPG were significantly higher in children with various severity of CKD than in the comparison group. The highest values of MMP-8 were observed in group 2 children with end-stage CKD on hemodialysis. Increased salivary OPG was noted in group 1 children with stage 1-2 CKD and in group 3 patients one year after the kidney transplantation. Conclusion. Saliva can be used as a biological fluid for diagnosis of preclinical stages of bone metabolism disorders in children with CKD, and salivary MMP-8 and OPG can be considered as predictive and prognostic markers.

Background: The progression of CKD occurs in five different stages in which there are gradual changes of GFR, serum creatinine and serum calcium.Objective: The study was undertaken to determine GFR in advanced stages of CKD and its relation with s. creatinine and s. calcium and also to find out the correlation between s. creatinine and s. calcium.Methodology: This study was carried out in the departments of Physiology and Nephrology, Rajshahi Medical College. All the advanced stage chronic kidney disease patients were taken as comparison. Apparently healthy persons were taken as control. Serum Creatinine was measured by alkaline picrate method; estimation of GFR was done by using Cockcroft- Gault formula and serum calcium was performed by analyzer.Result: In this study a total number of 120 subjects were included, out of which 30 were healthy control and 90 were diagnosed cases of advanced stages of CKD. Among the patients, 55 (61.12%) were male and 35 (38.88%) were female. Mean age (±SD) of the patients were 45 ± 11.16 (Range 20-65 years). While comparing between groups of CKD patients, it was found that s. creatinine of control group was significantly lower than that of group 1. Again s. creatinine of Group 1 was significantly lower than that of group 2 and similarly, s. creatinine of group 2 was significantly lower than that of group 3. On the other hand, s. calcium of control group was significantly higher than group 1, likewise s. calcium of group 1 was significantly higher than that of group 2 and s. calcium of group 2 was significantly higher than that of group 3.Conclusion: From this study the inference could be drawn that serum calcium had a positive correlation with GFR and a negative correlation with s. creatinine.J.

INTRODUCTION: Most of the chronic kidney disease (CKD) patients develop cardiovascular disease (CVD) in their later stages. Various traditional CVD risk factors are highly prevalent in CKD but mortality of these patients cannot be fully justified by these CVD markers. So this study was designed to determine serum calcium and phosphorus product (Ca×Pi) to predict CVD risk in CKD patients. MATERIAL AND METHODS We followed the guidelines of NKF-KDOQI for CKD diagnosis and staging. Further the patients were classified into 3 different groups based on Ca×Pi product; <40 mg2/dl2 (group 1), 40-55 mg2/dl2 (group 2) and >55 mg2/dl2 (group 3). We then evaluated CVD risk by various traditional risk factors like age, BMI, BP, smoking history, dyslipidemia, previous history of CVD, LVH, arrhythmia, VHD, cardiomyopathy, and IHD. RESULTS: Higher level of Ca×Pi was associated with presence of LVH (32.30% in group 1, 31.42% in group 2 and 46.66% in group 3), Arrythemia (13.84% in group 1, 28.57% in group 2 and 46.67% in group 3), VHD (5.71% in group 2 and 10.00% in group 3), Cardiomyopathy (1.53% in group 1, 8.57% I group 2 and 6.66% in group 3), IHD (6.15% in group1, 11.42% in group 2 and 13.33% in group 3) and hypercholesterolemia, hypertriglyceridemia and increased LDLc. CONCLUSION: This study found that higher Ca×Pi increases with decline in glomerular filtration rate (GFR) and associated with CVD risks and CVD. So, this study raise a potential need to evaluate the level of calcium and phosphorus in all CKD patients and the level should be monitored more thoroughly to prevent CVD.

ABSTRACT INTRODUCTION The SARS-CoV-2 pandemic has emerged as perhaps the most challenging global health problem of this century. The concomitant presence of co morbidities like chronic kidney disease (CKD), diabetes, chronic heart disease etc. makes the task of patient management difficult. AIMS AND OBJECTIVES To assess the patterns of liver test abnormalities in patients of COVID 19 infection with and without CKD and evaluate the probable outcomes. MATERIALs and METHODS A cross-sectional retrospective observational study done on 600 patient samples (Group 1 COVID-19 without CKD, Group 2 COVID-19 with CKD and Group 3 non COVID-19 with CKD) which were processed for Liver function test (AST, ALT and ALP) and Renal function test (Urea and Creatinine) in the Department of Biochemistry, Dr. RML Hospital New Delhi. RESULTS AST and ALT levels were significantly higher (P < 0.05) in all COVID 19 positive patients group 1 mean and 2 SD, (63.63 and 42.89 U/L & 50.25 and 46.53 U/L respectively) and group 2 (90.59 and 62.51 U/L & 72.09 and 67.24 U/L respectively) as compared to Group 3 (25.24 and 7.47 U/L & 24.93 and 11.44 U/L respectively) and also a statistically significant elevation is seen in these two parameters (AST & ALT) in Group 2 as compared to Group 1 (P < 0.05). There was a negative significant correlation between eGFR and AST/ALT levels in Group 1 (p < 0.05). In Group 2, a weak positive correlation was seen with ALT (p < 0.01). No significant correlation existed between eGFR and ALP in groups 1 and 2. In Group 3, eGFR showed strong correlations with AST and ALT levels (p < 0.01) and reduction in kidney function correlated well with increase in serum ALP levels, (p < 0.01). CONCLUSIONS This study most comprehensively describes that SARS-CoV-2 positive CKD patients show more elevations in serum aminotransferase levels as compared to their non-CKD counterparts, in contrast to non-COVID-19 CKD cases. Serum ALT values in SARS-CoV-2 patients show significant correlation with calculated eGFR values. Elevated ALP values in CKD patients may be used as an indicator of declining kidney function. However, more studies in this direction are needed.

Abstract Background and Aims Impaired thyroid function is a common endocrine pathology among patients with chronic kidney disease (CKD), affecting metabolic parameters, including iron metabolism. The purpose of the study was to investigate potential relationship between thyroid status and iron metabolism profile in patients with type 1 diabetes (T1D) and DKD. Method We recruited 155 patients with T1D. GFR was estimated by CKD-MDRD formula. All patients were divided into 3 groups: the group 1 comprised 59 patients with GFR&gt;60 ml/min; group 2-77 patients with GFR&lt;60 ml/min, group 3- 19 patients, receiving renal replacement therapy (RRT). Biochemical parameters, HbA1c, thyroid hormones, iron homeostasis parameters were measured. Nonparametric statistical methods were used. A P-value &lt;0,05 was considered significant. Results Groups were matched by age of T1D manifestation, HbA1c, BMI, CKD duration in groups 2 and 3. Duration of T1D differed by groups. Comparative analysis of patients in the subgroups revealed reliable differences in TSH levels only between patients from group 1 (p= 0.009), however, in the whole sample and in RRT patients its levels remained within the reference interval. Groups differed by FT4 values (group 1 - 14.12 (12.70-16.25) pmol / L, group 2 - 14.52 (13.27-16, 21), 3 group - 12.25 (11.38-13.48), p1,2 = 0.143, p1,3 = 0.035, p2,3 = 0.003) and FT3 (1 group - 4.43 (4,02-4.89) pmol / L, 2 group - 4.27 (3.98-4.78), 3 group - 1.43 (1.31-1.57), p1,2 = 0.712, p1,3 = 0.002, p2,3 = 0.012) with a tendency to maximum decrease when receiving RRT. No significant differences were obtained according to the levels of total T4 and T3, TG, Ab-TG, AbTPO. Significant decrease in Ab-R-TSH levels (group 1 - 0.70 (0.44-1.67) IU / l, group 2 - 0.40 (0.30-0.88), group 3 - 0.30 (0.30-0, 52), p1,2 = 0.492, p1,3 = 0.009, p2,3 = 0.035) confirms the absence of the influence of autoimmune component on the genesis of thyroid disorders in patients with CKD. No differences were obtained between groups in terms of serum iron levels and total iron binding capacity. Patients significantly differed in ERYTHROCYTES levels (group 1 - 4.68 (4.41-5.01) 109 / l, group 2 - 4.59 (3.96-4.83), group 3 - 3.84 (3, 32-4.27), p1,3 &lt;0.001, p2,3 &lt;0.001), HEMOGLOBIN (group 1 -139.00 (129.00-154.00), group 2 - 135, 00 (115.50-145.00), group 3 - 115.00 (103.00-124.00), p1,2 = 0.025, p1,3 &lt;0.001, p2,3 &lt;0.001), HCT (1 group - 41.90 (39.20-45.10)%, group 2 - 40.75 (35.65-43.70), group 3 - 36.25 (32.90-41.20), p1,3 &lt;0.001, p2,3 = 0.055), TRANSFERRIN (group 1 - 32.90 (30.80-35.60) μmol / L, group 2 - 31.60 (19.20-35, 45) 3 group - 2.45 (2.14-3.65), p1,2 = 0.049, p1,3 &lt;0.001, p2,3 &lt;0.001) and FERRITIN (1 group - 54.00 (33.00- 74.97) μg / L, group 2 - 74.85 (37.18-109.90), group 3 - 152.60 (92.80-329.60), p1,3 &lt; 0,001, p2,3 = 0.001), which reflects the highest sensitivity of these indicators to decrease in renal function. HCT correlated with levels of total T3 (ρ = 0.489), AbTPO (ρ = -0.490), total T4 (ρ = 0.536). Hb levels correlated with total T4 levels (ρ = 0.811), fT3 (ρ = 0.483). Ferritin levels correlated with fT4 (ρ = 0.510), and transferrin with fT3 (ρ = 0.523). Serum iron levels correlated with AbTPO (ρ = -0.656). Conclusion According to revealed changes, possibly anemia contributes to the development of thyroid dysfunctions in patients with diabetic genesis of CKD, due to the involvement of iron in the processes of deiodination and peripheral conversion of thyroid hormones.

Abstract Introduction The use of natriuretic peptides has spread in recent years as a diagnostic tool in patients with heart failure (HF). However, its influence on the prognosis of these patients has not been clearly established. Thus, our main aim was to know the characteristics of patients with increased levels of NT-proBNP and to analyze its impact on long-term prognosis in terms of mortality and readmissions due to heart failure. Material and methods We selected cases from the heart failure unit at HURS which had a NT-proBNP determination at first consultation. Patients were divided into two groups: GROUP 1 (NT-ProBNP &lt;10000) and GROUP 2 (NT-ProBNP &gt;10000). Clinical, echocardiographic and treatment variables were collected and patients were followed up for readmissions due to heart failure and all-cause mortality. Results A total of 280 patients were selected. The mean age of the cohort was 66.74±13.88 years and was male-dominated (64%). In group 1, there was a higher initial left ventricular ejection fraction (LVEF) (43.19% vs 40.36%; p=0.057), lower basal creatinine (1.13 mg/dL vs 1.53 mg/dL; p=0.001), lower creatinine at the end of follow-up (1.27 mg/dL vs 1.79 mg/dL; p=0.001) and a lower NT-proBNP at the end of follow-up (4039 pg/mL vs 17140 pg/mL; p=0.000) than in group 2. In addition, group 2 showed a higher percentage of chronic kidney disease (55% vs 29%; p=0.000) than group 1, with no differences in their main variables. With 110 months of follow-up, patients with NT-proBNP levels&gt;10000 had a similar hospital readmission rate compared to the group with lower NT-proBNP levels (81.2% vs 84.8% log rank p=0.133).With a mean of 130.01±9.11 months of follow-up, patients with NT-proBNP levels&gt;10000 had a tendency to higher mortality from any cause than those with lower NT-proBNP levels (84.4% vs 48.4%, log rank p=0.000). Conclusion Patients with NT-proBNP levels&gt;10000 are associated with a lower LVEF at baseline and a higher proportion of chronic kidney disease. In the long term, patients with NT-proBNP levels&gt;10000 had the same rate of readmissions for heart failure but a higher rate of death from any cause.

Purpose. To examine the indicators of iron deficiency, the levels of hemoglobin, erythropoietin, hypoxia-induced factor 1-alpha (HIF-1α) in the blood of children with anemia and chronic kidney disease C1-5 prior to the dialysis and on its background, receiving and not receiving iron preparations and erythropoietin-stimulating drugs to establish the role of HIF-1α in the regulation of erythropoietin synthesis and erythropoiesis. Results. The patients (n=80) with anemia and chronic kidney disease were divided into 3 groups: Group 1: 32 patients with chronic kidney disease C1-5 prior to the dialysis, not receiving therapy; Group 2: 18 patients with chronic kidney disease C2-5 prior to the dialysis, receiving iron-containing preparations and erythropoietin-stimulating drugs; Group 3: 30 patients with chronic kidney disease C3-5 on dialysis, receiving iron preparations and erythropoietin-stimulating drugs. Group 1: we found the increased levels of erythropoietin (28.65 ± 3.66 MIU/ml) and HIF-1α (0.089 ± 0.011 ng/ml; p=0.014 and p=0.005, respectively); Group 2: 63.01 ± 14.84 mIU/ml and 0.138 ± 0.025 ng/ml; p=0.0088 and p=0.005, respectively). Group 3: we found the increased level of HIF-1α (0.098 ± 0.01 ng/ml; p=0.005).Conclusion. An increase in concentration of HIF-1α in children with anemia and chronic kidney disease C1-5 prior and on dialysis receiving and not receiving therapy with iron-containing drugs and erythropoietin-stimulating agents confirms the role of HIF-1α in the regulation of erythropoietin and erythropoiesis synthesis in anemia.

Background: Dyslipidemia is very much common in chronic kidney disease patients and is responsible for cardiovascular disease (CKD) which is most common cause of mortality in them. So, it is necessary to study the lipid prole in CKD patients to prevent morbidity and mortality. Methods: Subjects each of 50 in number are grouped into healthy controls (group-1), CKD patients without hemodialysis (group-2), CKD patients with hemodialysis (group-3). After fasting of 12 hours, lipid prole is assessed in all cases. Results: In this study, there is increase in Total cholesterol (TC), Low Density lipoprotein (LDL), very Low-Density lipoprotein (VLDL) and Triglycerides (TG) and decrease in High Density Lipoprotein (HDL) in all CKD patients compared to healthy controls (p-value for each parameter <0.001). There is increase in TC, TG and VLDL in diabetic CKD patients compare to non-diabetic CKD patients and p-value for each parameter is <0.05. It was found that TG and VLDL increase and HDL decrease in group-3 compare to group-2 is statistically signicant (p-value for each <0.05) and no signicant variation in TC and LDL in these groups. Conclusions: Present study demonstrated that there is dyslipidemia in CKD patients irrespective of mode of management, but the derangement is much more common and signicant in CKD with hemodialysis group and they are at risk of cardiovascular disease. It is better to start lipid lowering drugs which decreases disease progression and dyslipidemia.

Aim. To conduct comparative analysis of height, weight and body mass index in children with stages 1 to 3 of chronic kidney disease (CKD) caused by recurrent urinary tract infection due to congenital anomalies of kidney and urinary tract.Methods. The study was performed on 210 children: 110 patients examined in 2001-2002 (group 1) and 100 children examined in 2011-2012 (group 2). Stage 1 of CKD was observed in 94 (85.4%) children in group 1 and in 93 (93%) in group 2, stage 2 - in 16 (14.6%) and 7 (7%) patients, respectively. From both groups patients matched by sex, age, diagnosis and social status were selected: 20 patients with stage 1, 19 children with stage 2; in addition, 6 children with stage 3 were examined.Results. Nowadays children with CKD stage 1 are taller compared to patients of the beginning of the XXI century (Z-score: -0.14±1.43 and 0.20±0.98 respectively, p=0.01). Significant differences in weight were found in children with stage 1 in 2011-2012 compared to the patients in 2001-2002 (0.18±0.46 and 0.78±1.19 for groups 1 and 2, respectively, р=0.026). A tendency towards decrease of average height in children with stage 3 is observed compared to patients with stage 1, i.e. due to the progression of the disease.Conclusion. The data obtained reflect modern tendencies towards increase of children height and weight. No significant differences were found in physical development parameters of children with stages of chronic kidney disease 1 and 2 examined at the same time period but a tendency towards children’s height decrease from stages 1 to 3 of CKD of non-glomerular etiology was revealed.
