Effect of Different Induction Immunosuppression on the Incidence of Infectious Complications after Kidney Transplantation-Single Center Study.

Potent immunosuppression lowers the incidence of acute graft rejection but increases the risk of infections. In order to decrease either infectious complications or acute rejection, it is necessary to identify risk groups of patients profiting from personalized induction immunosuppressive treatment. The aim of our analysis was to find whether there were higher incidences of infectious complications after kidney transplantation (KT) in groups with different induction immunosuppressive treatment and also to find independent risk factors for recurrent infections.

High-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements: Biopsy analysis of 70 cases from the Slovak Lymphoma Registry.

We performed a twelve-year retrospective analysis of diffuse large B-cell lymphoma (DLBCL) patients' biopsies with rearrangements of genes MYC, BCL2, and/or BCL6, commonly referred to as double-hit and triple-hit high-grade B-cell lymphomas (DH/TH HGBL). Our aim was to present complex characteristics of the DH/TH HGBL group of patients diagnosed in the Slovak National Lymphoma Register together with the evaluation of the relationship between immunohistochemical (IHC) protein expressions of c-myc, bcl2, bcl6, and cyclin D1 in tissue specimens and the presence of rearrangements of their protein-coding genes by FISH analysis in order to find a clinically relevant diagnostic algorithm that would be the most time- and cost-efficient. For this study, a standard panel of histomorphological, IHC, and FISH methods was used to analyze the characteristics of 70 DH/TH HGBL patients' biopsies.

Acute kidney rejection after anti-SARS-CoV-2 virus-vectored vaccine-case report.

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.

Chondroblastoma of the Temporal Bone: A Case Report and Literature Review.

Introduction: Temporal bone chondroblastoma is a rare, locally aggressive tumour originating from immature cartilage, which recurs to a high degree. Treatment is surgical. Radiotherapy is reserved for recurrence.

Effect of mycophenolic acid and tacrolimus on the incidence of infectious complications after kidney transplantation.

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.

Living-Related Kidney Transplantation in a Patient with Juvenile Nephronophthisis.

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.

Kidney Transplantation and "Sex Mismatch": A 10-Year Single-Center Analysis.

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 AND METHODS Our retrospective analysis consists of 230 deceased donor/recipient pairs.

Kidney transplantation as a treatment of choice for AA amyloidosis due to periodic fever syndrome.

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.

Alcohol-Related Liver Disease as a New Risk Factor for Post-transplant Diabetes After Liver Transplantation.

Introduction: Post-transplant diabetes mellitus (PTDM) is a serious and frequent metabolic complication after the transplantation of solid organs. PTDM incidence 12 months after the transplantation is 2.5%-25%.

Induction Therapy With ATG Compared With Anti-IL2 Basiliximab in Low-Immunologic Risk Kidney Transplant Recipients.

Unlabelled: 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).

Role of sex in post-transplant diabetes mellitus development: Are men and women equal?

Introduction: Sex differences are defined as biology-linked differences between women and men that occur through the sex chromosomes and their effects on organ systems.

Material And Methods: The objective of this prospective study was to determine risk factors for post-transplant diabetes mellitus (PTDM) in men and women.

Results: A total of 417 patients (271 men and 146 women) were included in the monitored group.

Leptin - A new marker for development of post-transplant diabetes mellitus?

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.

Effect of Paricalcitol on Bone Density After Kidney Transplantation: Analysis of 2 Transplant Centers.

Introduction: The Kidney Disease: Improving Global Outcomes Clinical Practice Guidelines on the management of bone disease in patients with chronic kidney disease recommend periodic measurement of serum calcium, phosphorus, vitamin D, and parathyroid hormone levels after kidney transplantation, with the frequencies that will vary according to the severity of bone disease and graft function. Paricalcitol, a selective vitamin D receptor activator, is indicated in the prevention and treatment of secondary hyperparathyroidism.

Materials And Methods: We retrospectively evaluated the effect of treatment with paricalcitol among our kidney transplant recipients.

Genetic analysis of single-minded 1 gene in early-onset severely obese children and adolescents.

Background: Inactivating mutations of the hypothalamic transcription factor singleminded1 (SIM1) have been shown as a cause of early-onset severe obesity. However, to date, the contribution of SIM1 mutations to the obesity phenotype has only been studied in a few populations. In this study, we screened the functional regions of SIM1 in severely obese children of Slovak and Moravian descent to determine if genetic variants within SIM1 may influence the development of obesity in these populations.

KIT and PDGFRA mutations and the risk of GI stromal tumor recurrence.

Purpose: Mutated KIT and platelet-derived growth factor alpha gene (PDGFRA) drive GI stromal tumor (GIST) oncogenesis, but the clinical significance of their single mutations is known incompletely.

Patients And Methods: We identified 11 population-based series of patients with GIST through a literature search and pooled individual data from 3,067 patients treated with macroscopically complete tumor excision. Mutation analysis was done from 1,505 tumors.

Molecular mechanisms of virus spread and virion components as tools of virulence. A review.

Despite of differences in replication strategy among virus families, some basic principles have remained similar. Analogous mechanisms govern virus entry into cells and the use of enzymes which direct the replication of the virus genome. The function of many cell surface receptors (such as glycosoaminoglycans, glycoproteins, proteins) which interact with viral capsid proteins or envelope glycoproteins has recently been elucidated.

Early enteral feeding in severe acute pancreatitis: can it prevent secondary pancreatic (super) infection?

Sepsis continues to account for a second peak in mortality in patients with severe acute pancreatitis. The prevention of these septic complications and subsequent development of multiple organ dysfunction syndrome remains a major focus for investigators, yet despite considerable clinical and experimental work addressing its etiology, septic complications remain high. Several studies have been designed to demonstrate the mechanism of origin of these septic complications with an attempt to define strategies for their prevention to improve patient outcomes.
