Abstract

Background: The tacrolimus concentration-to-dose (C/D) ratio is valuable for optimizing nephrotoxicity-related renal outcomes. Prospective data on the C/D ratio in kidney transplant recipients newly treated with MeltDose tacrolimus are limited. We analyzed the C/D ratio pattern of MeltDose tacrolimus and its effect on posttransplant renal function, comparing it with the literature data on immediate-release tacrolimus (IR-Tac). Methods: In total, 101 adult kidney transplant recipients on a standard immunosuppressive regimen including MeltDose tacrolimus were enrolled in this prospective, multicenter cohort study and followed for 12 months. The C/D ratio classified patients as fast, intermediate, or slow metabolizers. Renal function was assessed via the estimated glomerular filtration rate (eGFR). MeltDose tacrolimus data were compared with previous IR-Tac data by bootstrapping. Results: The cohort exhibited a right-skewed C/D ratio distribution with a mean of 2.12 ng/mL × 1/mg, which was significantly greater than the 1.29 mean for IR-Tac (p < 0.001). Compared with fast metabolizers, slow metabolizers of MeltDose tacrolimus experienced greater eGFR gains at 6 months post-transplantation (median +7.9 vs. −3.6 mL/min; p = 0.005). A Bayesian linear mixed-effects model predicting the eGFR at month 12 identified the baseline eGFR, time from transplant, body mass index, and log-transformed C/D ratio as significant variables. A one-unit increase in the log-transformed C/D ratio corresponded to an approximate increase of 4.5 mL/min in the eGFR at month 12. Conclusions: Slow metabolizers of MeltDose tacrolimus had significantly better renal function outcomes than fast metabolizers. MeltDose tacrolimus is associated with slower metabolism than is IR-Tac, as evidenced by its higher C/D ratios. [ABSTRACT FROM AUTHOR]

Abstract

The main aims of thin biofilm synthesis are to either achieve a new form to promote the transport of drugs in oral delivery systems or as a coating to improve the biocompatibility of the implant’s surface. In this study, the Langmuir monolayer technique was employed to obtain films containing Mg-doped hydroxyapatite with 0.5%, 1.0%, and 1.5% Mg(II). The obtained modified HA particles were analysed via the FT-IR, XRD, DLS, and SEM methods. It was shown that the modified hydroxyapatite particles were able to form thin films at the air/water interface. BAM microscopy was employed to characterized the morphology of these films. In the next step, the mixed films were prepared using phospholipid (DPPC) molecules and modified hydroxyapatite particles (HA-Mg(II)). We expected that the presence of phospholipids (DPPC) in thin films improved the biocompatibility of the preparing films, while adding HA-Mg(II) particles will promote antibacterial properties and enhance osteogenesis processes. The films were prepared in two ways: (1) by mixing DPPC and HA-Mg (II) and spreading this solution onto the subphase, or (2) by forming DPPC films, dropping the HA-Mg (II) dispersion onto the phospholipid monolayer. Based on the obtained π–A isotherms, the surface parameters of the achieved thin films were estimated. It was observed that the HA-Mg(II) films can be stabilized with phospholipid molecules, and a more stable structure was obtained from films synthesied via method (2).

Abstract

Aim: The study aimed to evaluate the usefulness of contrast-enhanced ultrasonography in renal perfusion disorders caused by obstructive uropathy. Case description: We present a case of a patient with a horseshoe kidney, in which the urine outflow from the right part of the kidney was blocked due to the presence of a bladder tumour infiltrating the ureter. Perfusion disorders in both parts of the kidney, visible in computed tomography, were partially reflected in the ultrasound image. Conclusions: Doppler ultrasound and contrast-enhanced ultrasound may be useful for monitoring perfusion disorders in the course of obstructive uropathy, provided that appropriate methodology is developed to compare blood flow in both kidneys.

Abstract

Aim: 2D speckle tracking is a method used in myocardial strain assessment. However, several studies have confirmed the suitability of its application in the assessment of arterial strain (a marker of arterial stiffness). The aims of our study were to evaluate whether 2D speckle tracking can assess the changes in carotid and femoral strain caused by fluid loss during haemodialysis, and to determine the direction and amount of these changes. Material and methods: We examined the distal common carotid and proximal femoral arteries in 74 haemodialysed patients (28 women and 46 men) before and after their haemodialysis sessions. EchoPac software was used to analyse the recorded ultrasound examinations. Circumferential strain values were acquired for further analysis. Results: We found a decrease in carotid circumferential strain values after haemodialysis sessions (5.916 ± 2.632% before haemodialysis and 4.909 ± 2.409% after haemodialysis, p = 0.000022). The amount of fluid lost during haemodialysis sessions correlated (correlation coefficient of 0.434, p = 0.000222) with the decrease of carotid circumferential strain. The correlation coefficients were slightly higher (0.445, p = 0.000146) when a ratio of fluid loss volume to the BMI was used. No statistically significant changes were found in femoral circumferential strain. Conclusions: Our findings suggest that arterial response to body fluid loss may be assessed by 2D speckle tracking. This method enabled us to measure carotid circumferential strain changes caused by fluid volume contraction during haemodialysis sessions. We found an important decrease in the carotid circumferential strain values after the procedure. The amount of this decrease correlated significantly with the decrease in the volume of fluid lost during the haemodialysis session.

Abstract

Background: Patients with CKD are at an increased risk of developing vascular calcification (VC) and bone complications which translate into a higher morbidity and mortality. The dephosphorylated and uncarboxylated matrix Gla protein (dp-ucMGP) is considered to be an indicator of vitamin K2 status and correlates with markers of VC. It is activated by γ-glutamyl carboxylase that converts inactive MGP into an active form, and vitamin K2 is a cofactor of this reaction. The active form of MGP is a known inhibitor of arterial wall calcification and plays an important role in bone turnover. Recent studies show poor vitamin K2 status in CKD patients. We aimed to review the literature for the association between vitamin K2 status and calcification and bone disease risk and the efficacy of vitamin K2 supplementation in CKD population. Summary: Most CKD patients, including those on renal replacement therapy, have vitamin K2 deficiency. The dp-ucMGP level, a marker of vitamin K2 status, is decreased by vitamin K2 supplementation in CKD patients, but there is no unequivocal proof that it influences arterial calcification progression and bone complications. Key Messages: CKD population are at risk of vitamin K deficiency. Supplementation of vitamin K2 is safe and improves the serum markers of its deficiency. There is lack of strong evidence that vitamin K2 supplementation slows progression of calcification or reduces the frequency of bone complications. More prospective studies are needed.

Abstract

Abstract Background Ankylosing spondylitis (AS) is an insidiously progressive and debilitating form of arthritis involving the axial skeleton, characterized by chronic back pain and progressive spinal stiffness, and lessening of pain and stiffness with exercise. Due to subsequent manifestation in different organs, AS causes reduction in life expectancy, so early diagnosis and treatment are of great importance. No AS cases have been reported in solid-organ transplant recipients yet. Case presentation A 58-year-old woman with end-stage renal disease due to chronic glomerulonephritis, after allogenic kidney transplantation 25 years earlier, with stable, good graft function, treated with chronic immunosuppressive therapy based on cyclosporine A, mycophenolate mofetil, and prednisone, with no previous history of a connective tissue disease presented fever up to 39 °C accompanied by pain localized in sacroiliac region radiating to the left lower limb. Detailed diagnostic procedures and x-rays of the lumbar spine and of the targeted sacroiliac joints revealed lesions characteristic of AS. Sulphasalazine was added to standard immunosuppression regimen with good clinical results. Conclusions We report an adult kidney transplant recipient with a new onset of AS. The risk of relapse or new onset of inflammatory disease in transplant recipients is extremely low due to immunosuppressive therapy following transplantation. However, when it occurs, the clinical presentation is commonly atypical, often leading to delayed diagnosis.

Abstract

Background and Objectives: Intradialytic hypotension (IDH) complicates 4 to 39.9% of hemodialysis (HD) sessions. Vessels’ reactivity disturbances may be responsible for this complication. Two-dimensional speckle tracking is used to assess arterial circumferential strain (CS) as a marker of the effectiveness of the cardiovascular response to the reduction of circulating plasma. Materials and Methods: The common carotid artery (CCA) and common iliac artery (CIA) CSs were recorded using ultrasonography in 68 chronically dialyzed patients before and after one HD session. Results: In patients with IDH episodes (n = 26), the CCA-CS was significantly lower both before (6.28 ± 2.34 vs. 4.63 ± 1.74 p = 0.003) and after HD (5.00 (3.53–6.78) vs. 3.79 ± 1.47 p = 0.010) than it was in patients without this complication. No relationship was observed between CIA-CS and IDH. IDH patients had a significantly higher UF rate; however, they did not differ compared to complication-free patients either in anthropometric or laboratory parameters. Conclusions: Patients with IDH were characterized by lower pre- and post-HD circumferential strain of the common carotid artery. The lower CCA-CS showed that impaired vascular reactivity is one of the most important risk factors for this complication’s occurrence.

Abstract

Introduction: Tacrolimus (TAC) metabolism rate has the potential to impact graft function after kidney transplantation (KTx). We aimed to analyze the relationship between the early post-KTx TAC C/D ratio (blood trough concentration normalized by total daily dose) and kidney graft function in a 2-year follow-up. Methods: We retrospectively analyzed data from 101 post-KTx patients at 3, 6, 12, and 24 months after KTx to identify the C/D ratio cutoff value optimal for dividing patients into fast and slow TAC metabolizers. We investigated the relationship between their TAC metabolism rate and graft function. Results: Patients were divided based on the TAC C/D ratio at 6 months after KTx of 1.47 ng/mL * 1 mg.

Abstract

A forty-seven-year-old recipient in late period after kidney transplantation with chronic estimated glomerular filtration rate (eGFR) 30 mL/min/1.73 m2, fully vaccinated against COVID-19 was diagnosed with SARS-CoV-2 infection in November 2021. After an initially mild course of the disease, he developed multiorgan failure requiring periodic respiratory and dialysis therapy. Covid-19 disease was complicated by multiple infections such Clostridioides difficile infection, Streptococcus epidermidis bacteriemia, Klebsiella pneumoniae and Candida glabrata urinary tract disease, cytomegalovirus infection and oral candidiasis. In a short period, he was readmitted to the hospital twice with recurrent Klebsiella pneumoniae urosepsis. One of those hospitalizations was also complicated by another COVID-19 infection that was confirmed with non-reactive neutralizing antibody. Due to severe infections the patient required individualized modification of immunotherapy; however, due to their recurrence it was finally decided to be discontinued. The patient was also reintroduced to hemodialysis therapy and no infections occurred since then.

Abstract

Background and Objectives: Kidneys play a key role in maintaining the acid–base balance. The aim of this study was to evaluate the effect of a 3-month oral sodium bicarbonate administration on arterial wall stiffness, arterial pressure and serum nutritional markers in non-dialysed patients with chronic kidney disease (CKD) stages 3–5 and metabolic acidosis. Methods: Eighteen CKD patients with eGFR < 45 mL/min/1.73 m2 and capillary blood bicarbonate (HCO3) < 22 mmol/L were enrolled in this single-centre, prospective study. Anthropometric parameters, pulse wave velocity, 24-h ambulatory blood pressure measurements, blood and urine parameters were assessed at the beginning and at the end of the study. The patients received supplementation with 2 g of sodium bicarbonate daily for three months. Results: A significant increase of pH: 7.32 ± 0.06 to 7.36 ± 0.06; p = 0.025, HCO3 from 18.7 mmol/L (17.7–21.3) to 22.2 mmol/L (20.2–23.9); p < 0.001 and a decrease in base excess from −6.0 ± 2.4 to −1.9 ± 3.1 mmol/L; p < 0.001 were found. An increase in serum total protein from 62.7 ± 6.9 to 65.8 ± 6.2; p < 0.013 and albumin from 37.3 ± 5.4 to 39.4 ± 4.8; p < 0.037 but, also, NT-pro-BNP (N-Terminal Pro-B-Type Natriuretic Peptide) from 794.7 (291.2–1819.0) to 1247.10 (384.7–4545.0); p < 0.006, CRP(C Reactive Protein) from 1.3 (0.7–2.9) to 2.8 (1.1–3.1); p < 0.025 and PTH (parathyroid hormone) from 21.5 ± 13.7 to 27.01 ± 16.3; p < 0.006 were observed, as well as an increase in erythrocyte count from 3.4 ± 0.6 to 3.6 ± 0.6; p < 0.004, haemoglobin from 10.2 ± 2.0 to 11.00 ± 1.7; p < 0.006 and haematocrit from 31.6 ± 6.00 to 33.6 ± 4.8; p < 0.009. The mean eGFR during sodium bicarbonate administration did not change significantly: There were no significant differences in pulse wave velocity or in the systolic and diastolic BP values. Conclusion: The administration of sodium bicarbonate in non-dialysed CKD patients in stages 3–5 improves the parameters of metabolic acidosis and serum nutritional markers; however, it does not affect the blood pressure and vascular stiffness.

Abstract

Kidney disease; Cancer Enfermedad renal; Cáncer Malaltia renal; Càncer Onco-nephrology is a new field of medicine which combines many aspects of kidney injury in cancer patients and cancers in patients with kidney disease. This connection takes many forms and includes drug-induced nephrotoxicity, electrolyte disorders, numerous paraneoplastic syndromes and an increased rate cancers in dialysis and transplanted patients. The appropriate laboratory assessment of the kidney function allows to optimize chemotherapy and thus minimizes the risk of complications. This article focuses on acute kidney injury (AKI), chronic kidney disease (CKD), various electrolyte and acid-base disorders, the most common cancers after kidney transplantation and the kidney disorders associated with HSCT (hematopoietic stem cell transplantation). The possibility of the application of novel cancer therapy, such as cancer immunotherapy and proton therapy in transplant recipients was also discussed.

Abstract

Background/Aims: Desphospho-uncarboxylated matrix Gla protein (dp-ucMGP) is formed as a result of vitamin K insufficiency. The aim of this study was to investigate the association between plasma dp-ucMGP, kidney function and cardiovascular risk factors before and after 9-months substitution of vitamin K2 in non-dialysis patients with chronic kidney disease (CKD) stage 4 and 5. Methods: 38 CKD patients were supplemented for 270±12 days with 90 µg vitamin K2 and 10 µg cholecalciferol or 10 µg cholecalciferol alone. At baseline and at follow-up circulating calcium, phosphate, lipids, hemoglobin, albumin and total protein, dp-ucMGP, osteoprotegerin, fetuin A, osteocalcin and fibroblast grown factor 23 (FGF-23) were assessed. Proteinuria was assessed in the first morning void. Results: Baseline plasma dp-ucMGP was 1018.6±498.3 pmol/l and was significantly higher in patients at stage 5 CKD (1388.3 ±505.4 pmol/l) than at stage 4 (885.1±419.7 pmol/l), p=0.04. Vitamin K2 supplementation resulted in a decrease of dp-ucMGP level by 10.7%. Plasma dp-ucMGP was positively associated with proteinuria, serum creatinine, PTH and FGF-23; and inversely associated with glomerular filtration rate, serum hemoglobin and albumin. Conclusions: High dp-ucMGP level, reflecting a poor vitamin K status seems to be associated with kidney damage and may be also a marker of cardiovascular risk in CKD patients. Supplementation with vitamin K2 may improve the carboxylation status of MGP.

Abstract

Nurses’ work requires an exclusive devotion and commitment. Although it is particularly burdening and highly stressful, it is not well paid and has a low status in the social hierarchy. The aim of the study was: 1) assessment and validity of various aspects of job; 2) understanding emotions towards nurses’ work; 3) determination of job satisfac‑ tion perceived by studying nurses. The study involved 281 students of extramural complementary Nursing Course at the University of Warmia and Mazury in Olsztyn. The authors’ demographic questionnaire, the Work Description Inventory (WDI), the Job Affect Scale (JAS), and the Job Satisfaction Survey (JSS) were used in the study. The obtained results were statistically analysed. Students obtained the average performance in the above mentioned measures of job evaluation. As regards the evaluation of superiors and the work content, the results obtained in the tested sample were slightly elevated. In terms of the importance of various aspects of job evaluation, the relationship with colleagues as well as the content and hours of work were found to be the most important, while salary appeared to be the least important aspect. The evaluation of the affect at work showed that students achieved the average results using the positive emotions scale and low results on the negative affect scale. The job satisfaction index val‑ ues suggest that the students are on average satisfied with the work in their profession. On the basis of the performed study, the following conclusions can be drawn: 1) according to the students’ assessment, the relationship with col‑ leagues as well as the content and time of work are the most important aspects of work, whereas salary is the least significant; 2) more than half of the surveyed felt positive emotions at their workplace; 3) respondents were on aver‑ age satisfied with their work; 4) undertaking the extramural complementary nursing course is associated with stu‑ dents’ positive attitude towards the nursing profession and their place of work.

Abstract

Vitamin K, especially its K2 form, is considered to be a protective factor against developing vascular changes and bone lesions that are common complications in kidney transplant (KTx) recipients. There is a growing number of studies showing that KTx patients are at risk of vitamin K deficiency. The aim of this study was to evaluate the intake of vitamin K1 and K2 in the diet of patients in the late period after KTx. During a routine visit at one outpatient transplantation clinic in Central Europe, a diet survey questionnaire was filled in by 151 clinically stable KTx recipients and compared with medical history, anthropometric measurements and laboratory tests. Mean vitamin K1 intake was 120.9 ± 49 μg/day and vitamin K2 (MK, menaquinone) intake 28.69 ± 11.36 μg/day, including: MK-4: 25.9 ± 9.9 μg/day; MK-5: 0.1 ± 0.2 μg/day; MK-6: 0.2 ± 0.4 μg/day; MK-7: 0.2 ± 0.23 μg/day; MK-8: 1 ± 1.9 μg/day; MK-9: 0.9 ± 2.3 μg/day; and MK-10: 0.2 ± 0.5 μg/day. Our study showed that KTx recipients’ diets contained adequate amounts of vitamin K1, whereas the intake of vitamin K2 seemed insufficient.

Abstract

Success in treatment with hemodialysis (HD) and kidney transplantation (KTx) requires good adherence. The objective of this study was to evaluate adherence to pharmacotherapy and health recommendations among HD and KTx patients using subjective and objective measures.Two hundred thirty-nine enrolled patients, with 132 KTx (39F, 93M) and 107 HD (48F, 59M) completed a questionnaire regarding over-the-counter (OTC) medications and dietary supplements (DS), adherence to pharmacotherapy, lifestyle recommendations, and self-evaluation of knowledge on them. The surveys were supplemented with objective data from patients' medical records, including interdialytic weight gain and laboratory parameters.About 42.1% HD and 39.4% KTx patients reported using OTC medications without medical consultation (P = .677); 43.9% HD and 31.1% KTx used DS (P = .040); more HD than KTx failed to notify a doctor about it (52.2% vs. 21.4%; P .001). More HD patients skipped medication doses (33.6% vs. 9.7%; P .001). About 40.2% HD and 20.5% KTx patients drank alcohol (P .001), 22.4% HD and 10.5% KTx smoked (P = .013). About 46.7% HD and 66.4% KTx patients limited their caloric intake (P = .002), 73.8% HD and 84.9% KTx limited their salt intake (P = .030). HD patients drank 1.17 ± 0.57 L of fluids daily and KTx drank 2.51 ± 0.67 L (P .001). In HD patients, interdialytic weight gains positively correlated with dialysis vintage (R = 0.26, P = .02) and fluid (R = 0.28, P = .011) but not salt intake (P = .307). The variability of trough levels of calcineurin inhibitors was unrelated to use of DS or OTC medications. KTx rated their knowledge on recommendations higher compared with HD (mean score 4.0 ± 1.0 vs. 3.7 ± 1.0, P = .040).KTx recipients exhibit better adherence and rate their knowledge on recommendations higher than HD patients.

Abstract

Aim: 2D speckle tracking is a method used in myocardial strain assessment. However, several studies have confirmed the suitability of its application in the assessment of arterial strain (a marker of arterial stiffness). The aims of our study were to evaluate whether 2D speckle tracking can assess the changes in carotid and femoral strain caused by fluid loss during haemodialysis, and to determine the direction and amount of these changes. Material and methods: We examined the distal common carotid and proximal femoral arteries in 74 haemodialysed patients (28 women and 46 men) before and after their haemodialysis sessions. EchoPac software was used to analyse the recorded ultrasound examinations. Circumferential strain values were acquired for further analysis. Results: We found a decrease in carotid circumferential strain values after haemodialysis sessions (5.916 ± 2.632% before haemodialysis and 4.909 ± 2.409% after haemodialysis, p = 0.000022). The amount of fluid lost during haemodialysis sessions correlated (correlation coefficient of 0.434, p = 0.000222) with the decrease of carotid circumferential strain. The correlation coefficients were slightly higher (0.445, p = 0.000146) when a ratio of fluid loss volume to the BMI was used. No statistically significant changes were found in femoral circumferential strain. Conclusions: Our findings suggest that arterial response to body fluid loss may be assessed by 2D speckle tracking. This method enabled us to measure carotid circumferential strain changes caused by fluid volume contraction during haemodialysis sessions. We found an important decrease in the carotid circumferential strain values after the procedure. The amount of this decrease correlated significantly with the decrease in the volume of fluid lost during the haemodialysis session.

Abstract

Burnout is a response to stress, the source of which is the situation at work. This phenomenon concerns mainly representatives of professions whose essence is to work with people, including doctors, nurses, paramedics and others; their close committed interactions with others constitute the core of professional activity and determine the success and development. Participants of the study were 281 students of extramural complementary nursing course at the University of Warmia and Mazury, mostly aged 40-60 years, employed in hospital wards and with employment contracts. In the study, the authors’ demographic questionnaire of structuralized interview and the MBI questionnaire, developed by Maslach and Jackson, in the Polish version by Pasikowski (2004), were used. The obtained results were statistically analysed. The performed analysis of burnout has confirmed that emotional exhaustion is associated with the length of employment, the number of days off and the number of institutions where nurses were employed. We did not observe, however, any correlation with these variables between depersonalisation and a sense of the lack of achievements. Furthermore, no dependence of the severity of the professional burnout symptoms on the surveyed groups’ age was found. It turned out that the persons working in shifts system felt much stronger depletion of emotion than nurses working in a daily system. It was also observed that nurses employed in hospitals felt much stronger symptoms in both areas of occupational burnout than those working in other institutions. Furthermore, it was not confirmed that the absence of the sense of achievement depended on where the respondents were employed. Taking into account the reference levels of the three dimensions of burnout acc. to MBI it was found out that most respondents were characterized by a low value within the emotional exhaustion and depersonalisation and a high value in terms of a sense of the lack of achievement.
