    Abstract Introduction: Tacrolimus is metabolized mainly in the liver by the CYP3A enzyme family, with a particularly well-documented role of CYP3A5. CYP3A5 is also expressed in the renal tissue and is present in the transplanted kidney. To date, the association between donor CYP3A5 polymorphisms and transplant outcome remains poorly understood. The aim of this study was to assess the effect of donor CYP3A5 expression on early and long-term transplant outcomes.
    Methods: A retrospective cohort study including 207 patients who received kidney grafts from 110 deceased donors was conducted at a single Central European Center. Tissue samples from all donors were studied for CYP3A5 single-nucleotide polymorphism (rs776746). Death-censored graft loss within 5-year follow-up, acute rejection occurrence, and kidney function, measured using serum creatinine and MDRD eGFR, were compared between groups of patients with allografts from rs776746 carriers (CYP3A5 expressors) and noncarriers (CYP3A5 nonexpressors).
    Results: Recipients who received kidneys from CYP3A5 expressors (n = 24) were at significantly higher risk of death-censored graft loss within 5-year follow-up (adjusted HR, 95% CI: 6.82, 2.01-23.12; p = 0.002) and acute rejection within the 1st posttransplant year (adjusted OR, 95% CI: 4.62, 1.67-12.77; p = 0.003) than those who did not (n = 183). The median time to loss of function was 1.93 [IQR; 0.77-3.19] years.
    Conclusions: Donor CYP3A5 expressor status is associated with worse renal graft survival and a higher risk of acute rejection. Determination of donor CYP3A5 genotype is a potentially useful tool that may improve kidney transplant outcomes.

    Abstract Background: Amyloidosis is a very heterogeneous disease. Correct diagnosis is extremely important because of the various treatment options for different types of amyloidosis. This study presents a case report and literature review of the misdiagnosis of fibrinogen Aα-chain amyloidosis (AFib amyloidosis).
    Case presentation: We report a 65-year-old man diagnosed with proteinuria in 2009. The kidney biopsy revealed the presence of Congo red-stained amyloid deposits. During differential diagnosis, amyloid deposits were discovered in adipose tissue and gingiva. Bone marrow trephine biopsy showed a predominance of lambda chains presenting plasmocytes. Based on performed medical examination, light chain amyloidosis was identified. Therefore, the patient received high-dose melphalan and underwent successful autologous peripheral blood stem cell transplantation. However, proteinuria, worsening of the kidneys' function, and incorrect levels of free light chains were still observed. In 2019, due to continuous treatment failure, a previously acquired kidney biopsy was examined by mass spectrometry, and numerous fibrinogen deposits were identified. Recommended DNA analysis revealed that the patient had AFib amyloidosis. Therefore, chemotherapy treatment was abandoned, and successful kidney transplantation was performed.
    Conclusion: Today, it is essential for medical practitioners to remember the possibility of rare and hereditary types of amyloidosis. There are multiple cases where a diagnosis was wrong or delayed because of the atypical course of the disease, the coexistence of another disease, and the rarity of AFib amyloidosis, and all of these reasons may result in the wrong treatment that will delay the right therapy. However, with the new, more precise diagnostics methods, such situations will become rare.

    Abstract Epidermolysis bullosa (EB) is a hereditary genetic skin disorder, classified as a type of genodermatosis, which causes severe, chronic skin blisters associated with painful and potentially life-threatening complications. Currently, there is no effective therapy or cure for EB. However, over the past decade, there have been several important advances in treatment methods, which are now approaching clinical application, including gene therapy, protein replacement therapy, cell therapy (allogeneic fibroblasts, mesenchymal stromal cells), bone marrow stem cell transplant, culture/vaccination of revertant mosaic keratinocytes, gene editing/engineering, and the clinical application of inducible pluripotent stem cells. Tissue engineering scientists are developing materials that mimic the structure and natural healing process to promote skin reconstruction in the event of an incurable injury. Although a cure for EB remains elusive, recent data from animal models and preliminary human clinical trials have raised the expectations of patients, clinicians, and researchers, where modifying the disease and improving patients' quality of life are now considered attainable goals. In addition, the lessons learned from the treatment of EB may improve the treatment of other genetic diseases.

    Abstract BACKGROUND After renal transplantation, immunosuppressants should be administered to prevent organ rejection and prolong graft survival. One of them is tacrolimus, which is metabolized by the CYP3A enzyme family. The variability of the CYP3A5 gene in renal transplant recipients has been previously studied for its correlation with acute rejection and allogeneic kidney function. CYP3A5 enzyme is also present in the renal tissue, and its relevance has not yet been extensively investigated. This study aimed to evaluate the effect of donor and recipient CYP3A5 expression status on early and long-term transplant outcomes. MATERIAL AND METHODS Single-nucleotide polymorphism in CYP3A5 (rs776746) was analyzed in 95 kidney transplant recipients and their grafts. The effect of donor and recipient genotypes on the primary endpoint, which was the loss of the renal graft over 5-year follow-up, was assessed. The secondary endpoints were biopsy-proven acute rejection, proteinuria, delayed graft function, and renal function. RESULTS Patients who received a CYP3A5*1 allele-carrying kidney (n=16) were at greater risk of graft loss (adjusted hazard ratio, 95% CI: 10.61, 2.28-49.42, P=.003) than those with the CYP3A5*3/*3 genotype (n=79). Renal CYP3A5 expression was also a predictor of acute rejection between the 2nd and 12th post-transplant months (adjusted odds ratio, 95% CI: 4.36; 1.08-17.6, P=.038) and proteinuria at different time intervals. No effect of the recipient CYP3A5 genotype was observed. CONCLUSIONS The donor CYP3A5 genotype is associated with inferior transplantation outcomes. Local renal tacrolimus metabolism is a potential target for improving long-term transplantation outcomes.

    Abstract Background: Previous reports have established that patient CYP3A5 allelic variability may be the most important genetic contributor to interindividual variation in tacrolimus exposure in renal transplant recipients. However, CYP3A5 protein is expressed in the allogenic kidney. The aim of this study was to investigate the role of the renal CYP3A5 genotype in tacrolimus concentration-to-dose ratio within 3 years posttransplant.
    Methods: A retrospective cohort study of 90 renal transplant recipients and their donors evaluated the effect of the CYP3A5 single-nucleotide polymorphism (rs776746) on tacrolimus exposure. The area under the curve for tacrolimus concentration-to-dose ratio within 3-year follow-up was calculated and compared in kidneys carrying at least 1 CYP3A5*1 allele and those carrying the CYP3A5*3/*3 genotype.
    Results: A significant effect of CYP3A5 expression on tacrolimus exposure was observed in both donors (mean ± SD: 23.8 ± 7.9 vs 32.6 ± 7.4 ng/mL/mg, respectively; P < .001) and recipients (mean ± SD: 27.1 ± 8.0 vs 32.2 ± 7.9 ng/mL/mg, respectively; P = .034) and was lower when CYP3A5 enzyme occurred. Thus, new groups were formed: the group in which at least 1 of the pairs, donor or recipient, had a CYP3A5 expressing allele (n = 23) had lower exposure to tacrolimus compared with nonexpressors (n = 67; mean ± SD: 26.2 ± 7.6 vs 33.2 ± 7.4 ng/mL/mg, respectively; P < .001).
    Conclusion: Intrarenal metabolism of tacrolimus may affect both local and systemic drug exposure. Nonexpressors receiving kidneys with the CYP3A5*1 allele may benefit from higher tacrolimus doses to hasten achievement of target drug concentrations.

    Abstract Immunosuppressed patients are at higher risk of developing human papilloma virus (HPV) cancerous and precancerous lesions in the anogenital region Carcinogenesis after organ transplantation due to immunosuppressive therapy is the major cause of long-term negative transplantation results. This is a rationale for the improvement of transplantation programs with carcinogenesis risk stratification in patients referred for transplantation. There is a need for a study on HPV-related carcinogenesis also in terms of its risk factors in the population after organ transplantation. This study aimed to assess the morbidity of anogenital carcinoma in patients with HPV infection, including those after organ transplantation and evaluate risk factors for carcinoma occurrence in patients after organ transplantation and with HPV infection. Our analysis directly indicates the group of patients with a high risk of HPV-related oncological complications of immunosuppression in anogenital region.

    Abstract Augmented reality (AR) delivers virtual information or some of its elements to the real world. This technology, which has been used primarily for entertainment and military applications, has vigorously entered medicine, especially in radiology and surgery, yet has never been used in organ transplantation. AR could be useful in training transplant surgeons, promoting organ donations, graft retrieval and allocation, and microscopic diagnosis of rejection, treatment of complications, and post-transplantation neoplasms. The availability of AR display tools such as Smartphone screens and head-mounted goggles, accessibility of software for automated image segmentation and 3-dimensional reconstruction, and algorithms allowing registration, make augmented reality an attractive tool for surgery including transplantation. The shortage of hospital IT specialists and insufficient investments from medical equipment manufacturers into the development of AR technology remain the most significant obstacles in its broader application.

    Abstract Background: In recent years a systematic decrease in donation activity in Poland (15.4 vs 13.0) has been observed. A significant reduction has been noticed in Warsaw (36.2 vs 19.2) as well.
    Methods: Data on deaths of patients admitted to intensive care units (ICUs) of Warsaw hospitals in from 2014 to 2018 were analyzed. Analysis was conducted in compliance with the Helsinki Congress and the Istanbul Declaration. Population of the city during this period averaged 1,753,480, although specialized capital hospitals service substantially bigger area than Warsaw alone. There are 18,500 to 18,600 deaths affecting this population every year. A total of 333 patients diagnosed as having brain death were included in analysis.
    Results: In 42 cases (12.7%) data collection was given up because of lack of authorization. In all donors, death was diagnosed according to neurologic criteria. The most common causes were vascular brain diseases (64.1%) and craniocerebral trauma (21.4%). In 14.5% brain death occurred from other reasons. There are 20 hospitals with ICUs in Warsaw, which totals 318 intensive care beds. Program of identification of deceased organ donors was active in only 14 hospitals. A total of 243 potential donors (73%) were identified in the 3 most active hospitals.
    Conclusion: Analysis of ICU deaths of Warsaw hospitals showed a gradual decrease in the number of reported donors (from 75 in 2014 to 46 in 2018), although the number of all deaths did not decrease (the number of deaths in ICUs was on average 2.571/y).

    Abstract The outcomes of kidney transplantation depend on numerous factors and vary between transplant centers. The aim of this study is to assess the relationship between selected organizational factors, comorbidities, and patient and graft survival. This is a retrospective analysis of 438 renal transplant recipients (RTR) followed for 5 years. Patient and graft survival were evaluated in relation to hospitalization length, distance from the patient's residence to the transplant center, the frequency of outpatient transplant visits, and the number and type of comorbidities. Five-year patient and graft survival rates were 93% and 90%, respectively. We found significant associations of patient survival with the prevalence of pre-transplant diabetes, cardiovascular diseases, malignancies, the number of comorbidities, and the first post-transplant hospitalization length. The incidence of infections, cardiovascular diseases, and transplanted kidney diseases was 60%, 40%, and 33%, respectively. As many as 41% of RTR had unknown etiology of primary kidney disease. In conclusion, the organization of post-transplant care needs to be adapted to the multi-morbidity of contemporary RTR and include multi-specialist care, especially in the context of current problems related to the COVID-19pandemic. The high proportion of patients with undetermined etiology of their primary renal disease carry the risk for additional complications during their long-term follow-up.
