Introduction: The spread of the SARS-CoV-2 virus has caused severe problems for healthcare facilities and infrastructure worldwide. The development of rapid diagnostic tools, effective treatment protocols, and vaccines against the pathogen has accelerated. This work aims to elucidate the benefits of recombinant human monoclonal antibodies to slow the progression of SARS-CoV-2 variant B.1.617.2 infection (delta variant). Material and methods: This is a retrospective analysis with a 6-month follow-up involving all patients who received recombinant human monoclonal antibodies (MABs) casirivimab/ imdevimab at University Hospital Martin in November and December of 2021. Results: A total of 180 patients were enrolled in the cohort with a mean time to administration of symptoms were 6,01 +/-0,3 days in the group of vaccinated patients and 5,52+/-0,28 days in the group of non-vaccinated patients and a mean time to the resolution of symptoms were 4,37 +/-0,62 days in the group of vaccinated patients and 3,83 +/-0,3 days in the group with non-vaccinated patients. Of these patients, 13 developed bronchopneumonia (7,2%)—serious side effects after MAB administration were observed in 1 patient. Conclusion: Using recombinant human monoclonal antibodies casirivimab/ imdevimab to slow or to stop SARS-CoV-2 variant infection B.1.617.2 significantly affected the course of the disease. Quick diagnostics, identification of at-risk patients, and multidisciplinary collaboration are essential in COVID-19 management.

Since 2012, when The Kidney Disease: Improving Global Outcomes (KDIGO) initiative published the first recommendations for the management and treatment of glomerular diseases, there has been enormous progress in understanding pathogenesis, identifying new diagnostic biomarkers and treating these diseases. Rituximab had become a promisisng treatment option in patients with primary glomerular disease, as confirmed by several clinical studies, where it has led to a significant reduction in proteinuria and a reduction in the incidence of relapses of the underlying disease. In this work we present our experiences with rituximab treatment.We retrospectively analyzed 9 patients with primary glomerulopathy resistant to srandard immunosuppressive therapy who received rituximab as rescue treatment. We evaluated the effect of rituximab induction treatment on the development of quantitative proteinuria.By evaluating the 24-hour proteinuria before and after treatment, we demonstrated a statistically significant decrease in proteinuria in our group of patients immediately after the las dose of rituximab. We did not notice a significant change in renal function.Rituximab represents an effective alternative in the treatment of primary glomerulopathies, especially in cases of resistance to standard immunosuppressive therapy, which is shared by the clinical experience presented by us.

INTRODUCTION For kidney transplantation is indicated any patient with chronic kidney disease in the terminal stage, unless it has a contraindication for this operation. The aim of this work is to evaluate the benefit of diagnostic hospitalizations of the patients before inclusion on the waiting list for kidney transplantation and to identify the most common differential diagnostic problems for the indication / contraindication for kidney transplantation. MATERIAL AND METHODS This is a retrospective analysis, which included all potential recipients who underwent the examination process before inclusion on the waiting list and living donors in the form of diagnostic hospitalization at the Transplant Center at Martin University Hospital in 2016-2019. RESULTS A total of 49 patients were included in the cohort, the average length of hospitalization was 5.6 days. Kidney trans plantation subsequently underwent 22 of these patients, 3 patients were clearly contraindicated.

BACKGROUND AND AIMS Non-invasive diagnosis of graft rejection after kidney transplantation is still an unresolved issue. Changes in serum metabolite concentrations reflect the various processes involved in the graft, and thus graft rejection. Metabolomics approach might help with non-invasive diagnosis of graft rejection based on identification of T-cell activation. METHOD In a group of 55 patients after primary kidney transplantation (average follow-up 68.4 months, median 59 months) we identified patients with cellular rejection (ACR), antibody mediated rejection (AMR) and control group (CG)—patients without history of graft rejection. We used NMR metabolomic approach to determine the relative levels of metabolites in blood plasma. RESULTS From 23 evaluated metabolites: lactate was significantly increased in CG and in ACR against AMR (P AMR. When discriminating CG and AMR, Random Forest discriminatory algorithm performed with AUC = 0.849 when included also evaluated plasma creatinine and with AUC = 0.83 when creatinine was excluded (other metabolites with the highest discriminatory power were glutamine, lactate, tyrosine and BCKAs). CONCLUSION Metabolomic approach to blood plasma in patients after kidney transplantation seems to be very promising when looking for non-invasive techniques assessing graft viability/survival. The observed metabolomic changes were able to very well discriminate between patients with AMR and control group. However, discrimination of ACR against CG and AMR was rather poor.

BACKGROUND AND AIMS Adipose tissue, as an endocrine organ, is involved in the synthesis of hormones that are involved in several processes, including the regulation of food intake, the control of insulin sensitivity or as mediators of inflammatory processes. The aim of this study was to determine the importance of leptin, adiponectin, interleukin 6 and interleukin 10 levels for the development of post-transplant diabetes mellitus (PTDM) 1 year after kidney transplantation (KT). METHOD In the prospective analysis, the studied sample (n = 104) was divided into three groups: (1) control group, (2) patients who developed a pre-diabetic condition after KT (impaired glucose tolerance, fasting hyperglycemia) and (3) patients who developed de novo PTDM. Pre-transplantation and subsequently at 3, 6 and 12 months after KT, we recorded the basic characteristics of the donor and recipient, including parameters reflecting graft function, metabolic (lipid profile, glucose metabolism parameters) and anthropometric parameters. At the same time, we monitored the levels of adipocytokines (adiponectin, leptin) and interleukins (IL-6, IL-10) during the monitored period (Table 1). RESULTS The level of leptin in the post-transplant period had a continuously decreasing tendency in the control group with a significantly lower level 12 months after KT (P = 0.0078). On the other hand, after transient decrease, leptin level remained high in 12 months after KT in the group with prediabetes (P = 0.0343) and PTDM (insignificant). In contrast, adiponectin levels showed a significant decrease after 12 months in the group with prediabetes (P = 0.0009) and PTDM (P CONCLUSION We confirmed that elevated leptin level 12 months after KT is associated with the development of PTDM. Levels of inflammatory process mediators (IL-6 and IL-10) did not correlate with an increased incidence of metabolic complications. Their importance seems to apply in the event of acute rejection, which requires further investigation.

Nephronophthisis (NPHP) is an autosomal recessive disease manifesting as tubulointerstitial nephritis uniformly progressing to ESRD in approximately 5–10% patients in childhood. Living donor transplantation is the most beneficial mean of renal replacement therapy compared to other methods. However, living kidney donation is contraindicated in potential donor with diseases of autosomal dominant mode of inheritance potentially leading to kidney failure in future. On the other hand, autosomal recessive genetic kidney diseases, such as NPHP, are not usually contraindication to living kidney donation. Herein, we are reporting related living kidney transplantation with a family history of NPHP form 46-year-old mother (heterozygote) to 17-year-old daughter with (autosomal recessive homozygote) with focus on donor follow-up after nephrectomy.

Background White adipose tissue secretes a number of peptide hormones. The aim of this paper was to determine the role of leptin, adiponectin and interleukin-10 and interleukin-6 on the development of graft rejection in protocol biopsy after kidney transplantation. Methods In a prospective analysis (n = 104), we monitored the values of leptin, adiponectin, IL-6, and IL-10 prior to the transplantation and in the 3rd month after the transplantation. The protocol biopsy of the graft was performed in the 3rd month after the transplantation. The group was divided into the following according to the biopsy result: negative result, IFTA 1, borderline, and DSA positive. Results After adjusting for the differences in the baseline recipient and donor characteristics, we identified the hyperleptinaemia baseline (HR = 2.0444, P = 0.0341) and month 3 (HR = 49.8043, P

Background: Kidney transplant recipients appear to be at higher risk for critical COVID-19. Our analysis aimed to identify the possible risk factors for a severe course of the COVID-19 disease and to determine the influence of selected human leukocyte antigens (HLAs) on the course of the disease.Methods: This is a retrospective, multicenter analysis that included patients that were confirmed to be severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) positive after kidney transplantation (KT). The group of patients was divided into two subgroups according to the course of the infection, as follows: non-hospitalized and hospitalized.Results: A total of 186 patients (men, 69.4%) with confirmed SARS-CoV-2 positivity were included in the group. The following independent risk factors for the outcome of hospitalization were identified: the age at the time of infection [odds ratio (OR) = 1.19, P < 0.0001], a body mass index (BMI) >29.9 kg/m2 (OR = 7.21, P < 0.0001), P = 0.0008), and HLA-DQ2 with a protective nature (OR = 0.05, P = 0.0034).Conclusions: Higher doses of corticosteroids (>7.5 mg/kg) in standard immunosuppressive regimes and HLA-DQ2 appear to be protective factors in our analysis.

COVID-19 infection remains a threat to the health systems of many countries. Potential success in the fight against the COVID-19 pandemic is the vaccination of high-risk groups, including patients with end-stage kidney disease (ESKD) and after solid organ transplantation (SOT). Immunosuppression in kidney transplant recipients can also reduce the immunogenicity of SARS-CoV-2 vaccines (varied by vaccine platform), available data suggest that they are efficacious in approximately 50–70%, compared to non-transplant situations. In this paper, we present a newly developed acute humoral and cellular rejection with acute allograft failure and need of hemodialysis 14 days after administration of the adenovirus vectored SARS-CoV-2 vaccine (AstraZeneca; CHADOx1, AZD1222). This occurred in a patient who previously had an asymptomatic COVID-19 infection. Case reports of acute allograft rejection after vaccination against SARS-CoV-2 can help stratify risk groups of patients who develop hyperimmune reactions. However, it is also possible that those with a previous mild primary COVID-19 infection may also develop acute allograft rejections upon COVID-19 re-infection.

Sex differences are defined as biology-linked differences between women and men that occur through the sex chromosomes and their effects on organ systems.The objective of this prospective study was to determine risk factors for post-transplant diabetes mellitus (PTDM) in men and women.A total of 417 patients (271 men and 146 women) were included in the monitored group. Age at the time of kidney transplantation (KT)60 years and hypovitaminosis D at the time of KT (20 μg/l) were identified as independent risk factors for PTDM in both men and women. It was further confirmed as an independent risk factor for men a waist circumference at the time of KT94 cm, C-peptide at the time of KT5 ng/ml, HOMA-IR2 and triacylglycerols at the time of KT1.7 mmol/l. In case of women, the dominant factor was BMI at the time of KT30 kg/m2 and menopause at the time of KT. A significant decrease in C-peptide was recorded in women with PTDM.It was confirmed that there are gender differences with regard to the development of PTDM after KT. Women show pancreas β cell dysfunction, whereas insulin resistance and metabolic syndrome are dominant in men.

Introduction Infectious complications remain a common cause of mortality after kidney transplantation (KTx). Goal of effective immunosuppressive treatment (IS) must be balanced between decreasing incidence of acute kidney rejection (AKR) and avoiding the incidence of infections, at the same time. Materials and methods The aim of our analysis was to identify the risk of fixed daily dose (DD) of mycophenolic acid (MPA) and levels of tacrolimus (TAC) in the development of a single, recurrent infection and AKR after KTx. Results Our analysis consisted of 100 patients after KTx (66 males, 34 females). MPA DD > 1080 mg was a risk factor (RF) for recurrent infection in general (OR 1.2964;P = 0.0277), for recurrent bacterial infection from 1st to 6th month (OR 1.2674;P = 0.0151), recurrent bacterial infection (OR 1.2574;P = 0.0436), single viral infection (OR 1.2640;P = 0.0398) from 6th–12th month after KTx. MPA DD > 1080 mg and levels of TAC above recommended levels were not independent RF for the incidence of the infection. Conclusion MPA DD > 1080 mg as a RF for recurrent infection starting in the 1st month after KTx with significant association between the incidence of infections and MPA DD and TAC levels, without increased risk of AKR. In the centers with fixed dosing of IS, this can lead to lowering the risk of infections by decreasing MPA DD 1 month after KTx without increasing risk of infections.

Background and Aims The incidence of post-transplant diabetes mellitus (PTDM) after kidney transplantation (KT) is high and ranges from 15-30%. Insulin resistance (IR) at the time of KT is the most significant risk factor for the development of PTDM in patients after KT, as demonstrated by several analyzes. It is possible to reduce the high incidence of PTDM by influencing just modifiable risk factors, including obesity and the associated IR. The aim of this work is to determine the effect of precisely determined physical activity and lifestyle changes on IR and other risk factors for PTDM in patients after KT. Method This is a prospective controlled analysis, which included 44 patients after primary KT in the Martin Transplant Center. Half consisted of a study group (n = 22) whose patients were assigned to perform regular physical activity. The primary goal was to complete at least 150 minutes of moderate intensity physical exertion per week. They performed an aerobic or combined (aerobic + anaerobic) type of sports activity. Monitoring was provided by a sports tracker (Xiaomi Mi Band 3 compatible with Mi Fit mobile application). The other half was made up of a control group. The exclusion criterion at that time was already diagnosed with diabetes mellitus or a pre-diabetic condition. IR was assessed using the HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) index from fasting blood glucose and insulinemia values. Each patient underwent an oral glucose tolerance test (oGTT) at the end of follow-up. Patients in both groups have the same immunosuppressive protocol. The duration of follow-up was 6 months. Results In the observed group we univariately found in the 3rd and 6th month of monitoring significantly lower waist circumference (P = 0.0437, P = 0.0372), better graft function (P = 0.0036, P = 0.0137), lower value glycemia (P = 0.0016, P = 0.0003), C-peptide (P = 0.0447, P = 0014) and lower low-density lipoprotein (LDL) at 6 months (P = 0.0444) compared to the control group. We confirmed a statistically significantly lower IR at 6 months (P = 0.0202) and fasting blood glucose at 3 and 6 months (P = 0.0227) by multivariate analysis in the observed group. After the end of the follow-up, we identified statistically significantly fewer patients with a negative oGTT result in the control group (P < 0.0001), significantly more patients with impaired glucose tolerance, fasting hyperglycemia (P = 0.0078) and diagnosed with PTDM (P = 0.0212). In the control group, we found a statistically significant increase in glycemia at 30 (P = 0.0034) as well as at 120 minutes (P = 0.0011) during oGTT compared to the observed group. Conclusion In our study, we confirmed a significant effect of regular physical activity in preventing the development of IR and associated pre-diabetic conditions and PTDM.

Background and Aims Kidney transplantation (KTx) remains the most effective type of kidney replacement therapy. Infectious complications remain a common cause of mortality, especially during the first year after KTx. Goal of effective immunosuppressive treatment (IS) must be balanced between the decreasing incidence of acute rejection by maintaining effective levels of IS and at the same time avoiding the incidence of infectious complications caused by dose-dependent toxicity of IS. Method The aim of our analysis was to identify the risk of fixed daily doses of mycophenolic acid (MPA) and concentration controlled doses of tacrolimus (TAC) in the development of a single, recurrent infection and acute rejection after KTx. Results Our analysis consisted of 100 patients after KTx (66 males, 34 females) with anti-thymocyte globulin as an induction IS. We monitored the incidence of single, recurrent infection in 1st month, from 1st to 6th month and from 6th to 12th month after KTx and the incidence of acute kidney rejection in 1st year after KTx. According to multivariant analysis, Daily dose of MPA > 1080 mg and levels of TAC above recommended levels were not independent risk factors for the incidence of the infection. Daily dose of MPA > 1080 mg was a risk factor for recurrent infection in general (OR 1.2964; P = 0.0277), for recurrent bacterial infection from 1st to 6th month (OR 1.2674; P = 0.0151), recurrent bacterial infection (OR 1.2574; P = 0.0436), single viral infection (OR 1.2640; P = 0.0398) from 6th to 12th month after KTx We did not confirmed levels of TAC, above recommended levels in observed periods, as a risk factor for single or recurrent infection regardless of its etiology. We confirmed, incidence of mycotic infection in 1st month after KTx correlated with average level of TAC (13.4 ± 3.2 ng/ml) (P = 0.0300) and with average MPA daily doses (1200 ± 360 mg/day) (P = 0.0203). Correlation between the average daily doses of MPA (730 ± 380 mg/day) and the incidence of bacterial infection (P = 0.0161) and viral infection (P = 0.0161) from 1st to 6th month after KTx were found. We confirmed correlation between the incidence of bacterial infection and the average daily doses of MPA (630 ± 340 mg/day) from 6th to 12th month after KTx (P = 0.0479). By probit dose regression, we confirmed statistical significance between levels of TAC and the incidence of bacterial, mycotic and multidrug-resistant (MDR) infection, correlation between the daily dose of MPA and the incidence of mycotic infection in 1st month after KTx. We found statistical significance between levels of TAC and MDR infection and daily dose of MPA and the incidence of bacterial, mycotic and MDR infection from 1st to 6th month after KTx and we found statistical significance between the daily dose of MPA and the incidence of MDR infection from 6th to 12th month after KTx. In our study, we did not confirmed statistical significance between levels of TAC, daily dose of MPA and the incidence of acute kidney rejection. By logistic regression, neither levels of TAC below recommended values nor daily dose of MPA < 1080 mg were found as an independent risk factors for the incidence of acute kidney rejection. Conclusion In our analysis, we found dose of MPA > 1080 mg/day as a risk factor for recurrent infection starting in the 1st month after KTx and correlation between the incidence of the infections and daily dose of MPA 1 month after KTx, with significant association between the incidence of infections and daily doses of MPA and levels of TAC, without increased risk of acute kidney rejection. In the centers with fixed dosing of IS, this can lead to lowering the risk of infections by decreasing daily doses of MPA 1 month after KTx without increasing risk of infections.

Background and Aims Number of older patients with end stage kidney disease has been increasing, therefore there are increased number of older kidney transplant recipients. Potent immunosuppression (IS) used in patients after kidney transplantation (KTx) lowered the incidence of acute kidney rejection but increased the risk of post-transplant infection and sepsis as the most common non-cardiac cause of death. Older adults are at high risk of infections due to functional impairment and multiple comorbidities leading to poor outcome after KTx. Nowadays, no change in IS or prophylactic therapy is recommended based on the age of an adult KTx recipient. Female gender may be risk factor for infection after KTx due immunomodulatory effect of sex hormones such as estradiol. Methods The aim of our analysis was to find whether there are sex differences in the incidence of single and repeat infection and whether there is increased incidence of single and recurrent infectious complications in older kidney transplant recipients. Results Our analysis consisted of 100 patients after KTx (66 males, 34 females), average age 47,5 ± 12,6 years, treated with anti-thymocyte globulin as an induction IS. Male gender was a protective factor for the incidence of following infections in the 1st month after KTx: infection in general (P = 0.0054), recurrent infection (P = 0.0239), bacterial (P = 0.0125) and mycotic infection (P = 0.0103), recurrent bacterial infection (P = 0.0258). From the 1st to 6th month after KTx, female gender was identified as a risk factor for the incidence of infection in general (P = 0.0218), bacterial (P = 0.0186) and mycotic infection (P = 0.0318), repeat infection (P = 0.0216), recurrent bacterial infection (P = 0.0368). From 6th to 12th month after KTx, female gender was found as a risk factor for the incidence of bacterial infection (P = 0.0144), single infection (P = 0.0355), recurrent infection (P = 0.0007), single bacterial infection (P = 0.0309). Age > 60 years was not found as a risk factor for the incidence of single, repeat infection regarding its etiology. In our analysis we did not found correlation between gender and the incidence of single or recurrent infection of any etiology, we did not find significant differences in the severity of infections reflected by need for hospitalization, intensive care unit or use of vasopressors neither in gender, nor in older patients. In our study we did not confirm gender or age as a risk factor for the acute kidney rejection. Conclusion In our analysis, we found significant sex differences in the incidence of bacterial, viral, mycotic, single and repeat infection in different time intervals after kidney transplantation, while we did not confirmed age > 60 years is a risk factor for the infectious complications after KTx.

Background and Aims Renal AA amyloidosis is the most serious complication of periodic fever syndrome, which, inadequate suppression, due to persistent inflammation, leads to nephrotic syndrome and renal failure over several years. In most cases, periodic fever syndromes begin to manifest clinically in early childhood. Occurrence in adulthood is considered rare and is associated with a poorer clinical course. Kidney transplantation is an effective and safe treatment for end-stage chronic kidney disease (CKD) based on AA amyloidosis. Method We present cases of two patients after deceased donor kidney transplantation, who have been diagnosed with adult periodic fever syndrome. Conclusion Periodic fever syndromes are diseases beginning to manifest clinically in early childhood in 60–90% of cases, most often in the case of familial Mediterranean fever around 4 years of age, in the case of CAPS usually only a few months after birth. Occurrence in adulthood is considered rare and is associated with a poorer clinical course. Kidney transplantation is an effective and safe treatment of end-stage CKD based on AA amyloidosis associated with periodic fever syndrome. Adequate targeted treatment against IL-1 or TNF is important and appears to be safe during the post-transplant period, with regular monitoring of renal function, acute phase inflammatory reactants, and histological findings by protocol graft biopsies. It will be important and necessary to assess the development of diseases in the post-transplant period in the long term.

Background The effect of a relative disproportion in the size of a transplanted kidney (KT) on graft function and survival is well documented. However, the importance of the H-Y antigen (male donor and female recipient) has not been unambiguously confirmed. Material/Methods Our retrospective analysis consists of 230 deceased donor/recipient pairs. The aim of the study was to determine the effect of sex mismatch between donors and recipients on the function of the graft and the graft and patient survival. Results In the group of male donors, a statistically significantly lower value of the eGFR (estimated glomerular filtration rate) was recorded for female recipients in the fifth year after the KT (=0.0047). The male donor/female recipient group was an independent risk factor for: eGFR (45 years old in the fifth year [HR 11.1676; (P=0.0139)], the age of the donor was ≤50 years old/recipient was ≤45 years old in the third year [HR 1.2500; (P=0.0050)], and also in the fifth year after KT [HR 8.1993; (P=0.0183)]. Conclusions Based on our analysis, the differences in the incidence of acute rejection episodes as well as in graft survival among the different groups of patients were confirmed. The group with the highest risk, in cases of an acute rejection episode, is a male donor/female recipient.

Background and Aims Cardiovascular diseases (CVD) are the most frequent cause of death in dialysed patients. Patients in the risk group of CVD examined prior to kidney transplantation (KTx) are indicated for coronarography (SCG). The aim of our analysis was to identify risk factors (RF) for positive finding of patients undergoing SCG before KTx. Method Our analysis consisted of 55 dialysed patients (46 males, 9 females, P Results Patients without percutaneous coronary intervention (PCI) (negative finding) we confirmed significantly lower incidence of diabetic nephropathy (P=0.0484) IHD (P=0.0174) and coronary artery disease (P=0.0001). We confirmed, haemodynamically significant coronary stenosis correlate with the occurrence of stroke or transient ischemic attack in patient’s history (P=0.0104). Consequently, we identified predictors for realization PCI (positive result): type 2 DM [OR 2,3492 (P=0.0472)], HDL ≤ 1,03 mmol/l [OR 4.3276 (P=0.0359)], total calcium level ≤ 2mmol/l [OR 2.4935 (P=0.0309)], phosphate level ≥ 1.45 mmol/l [OR 0.2034 (P=0.0351)]. In our analysis, patients non-listed on WL had significantly higher incidence of type 2 DM (P=0.0087), smoking (P=0.0079) and were treated more often with statins (P=0.0025). Conclusion In our analysis, patients with DM and poorly managed chronic kidney disease - mineral bone disease are the most at risk group in the group of patients with CVD with positive SCG finding. Patients with high cardiovascular risk, without DM or other RF can profit from non-invasive imaging methods following faster listing on WL.

Background and Aims Kidneys from expanded criteria donors with diagnosis of brain death have become a part of the organ transplant program, which have thus increased the number of transplants. Method In this retrospective analysis, we identified the expanded criteria donors in a group of 156 kidney donors at our center. Basic parameters of the donors before kidney recovery were collected. Graft function, graft survival, and patient survival at 1, 3, and 5 years posttransplant were compared in expanded criteria versus standard criteria donors. Results Expanded criteria donors were significantly older than standard criteria donors (P < .001), had higher body mass index (P = .006), and had more frequent arterial hypertension (P < .001) and diabetes mellitus (P = .004) in their histories. When we considered the estimated glomerular filtration rate, graft function in the first 6 months after transplant was significantly worse in kidneys from expanded criteria donors (P = .011). In addition, recipients of grafts from expanded criteria donors had significantly worse survival in the first year posttransplant (P = .023); however, no differences in graft survival were observed. Conclusion From the long-term aspect, graft function and graft and patient survival in cases of kidneys from expanded criteria donors were comparable to results with kidneys from standard criteria donors. Expanded use of organs available for transplant is important due to the constantly increasing demands versus limited offers of organs.

Renal AA amyloidosis is the most serious complication of periodic fever syndrome, which, inadequate suppression, due to persistent inflammation, leads to nephrotic syndrome and renal failure over several years. In most cases, periodic fever syndromes begin to manifest clinically in early childhood. Occurrence in adulthood is considered rare and is associated with a poorer clinical course. Kidney transplantation (KT) is an effective and safe treatment for end-stage chronic kidney disease (CKD) based on AA amyloidosis. In this paper, we present cases of two patients after deceased donor KT, who have been diagnosed with adult periodic fever syndrome. In the first one, diagnosis and treatment began in advanced stage of CKD and therefore underwent KT with compensated disease, while in the second patient, the disease manifested and diagnosed in the post-KT period. Timely initiation of treatment ensured protection of the graft from amyloid deposition.

Practically all kidney allograft recipients require immunosuppressive therapy to prevent rejection and loss of the allograft. The aim of this study was to determine the occurrence of biopsy-proven acute rejection in low–immunologic risk kidney transplant recipients according to the type of induction (basiliximab vs low-dose of rabbit antithymocyte globulin [rATG], 3.5 mg/kg). Materials and Methods A total of 125 patients after primary kidney transplant were included in the retrospective analysis with 6-month follow-up. The immunosuppression regimen included tacrolimus, mycophenolic acid, and corticoids. Results We did not find any significant difference in the occurrence of acute rejection or difference in the occurrence of infection complications. Patients in the rATG group had a significantly longer period of cold ischemia, more frequently received kidney transplants from expanded criteria donors, and had significantly more mismatches in HLA-DR. Delayed graft function (DGF) was identified as an independent risk factor for biopsy-proven acute rejection (hazard ratio, 3.4859; P = .003). There was comparable incidence of DGF between the 2 groups despite that there were several factors that are more commonly associated with DGF in the rATG group. Conclusion Patients with low immunologic risk and high risk of DGF benefit from the rATG induction in dose of 3.5 mg/kg without the increased risk of infection complications with the assumption of good graft function in long-term post-transplant period.

Introduction Obese patients have increased leptin production and selective resistance to its central anti-adipogenic effects, yet its pro-inflammatory immunostimulating effects persist. Material and methods In a group of 70 patients who underwent primary kidney transplantation (KT) we examined adiponectin and leptin levels at the time of KT and 6 months post-transplantation. Patients with diabetes mellitus type 1 or type 2 at the time of KT were excluded from the study. Results We found that leptin levels significantly increased during the post-transplant period (P = 0.0065). Overall, leptin levels were positively correlated with the level of triacylglycerols, post-transplant diabetes mellitus (PTDM) development and acute rejection (AR). We discovered that, in particular, high leptin levels were associated with AR [OR 2.1273; 95% CI 1.0130–4.4671 (P = 0.0461)] and PTDM development [OR 7.200; 95% CI 1.0310–50.2836 (P = 0.0465)], whereas, low adiponectin levels represent a risk factor for the development of insulin resistance [HR 38.6135; 95% CI 13.3844–67.7699 (P Conclusion We found that a high serum concentration of leptin before KT is associated with both PTDM development and AR and merits further investigation in relation to KT.
