Abstract
Chronic kidney disease (CKD), diabetes and cardiovascular disease constitute three interrelated conditions of strong public health relevance. Elderly individuals account for the largest and the most rapidly growing age segment of the end-stage renal disease population. The elderly are affected by the same types of kidney diseases as younger individuals, but aging itself is associated with a gradual reduction in estimated glomerular filtration rate, which leads to the diminishment of the functional reserve and makes an individual more vulnerable to injurious effects of hypertension, cardiovascular disease, diabetes, and drugs' toxicity. Although the spectrum of diseases affecting people aged ≥65 is the same as in younger population, there are some distinct differences in the frequency of certain nephropathies between these two age groups. The superimposition of aging-related lesions on other kidney diseases evolving in the elderly population makes the clinical picture more complex and reaching diagnosis more challenging. In elderly CKD patients the high prevalence of comorbidities and the often aberrant metabolism of medications have to be considered in individually tailored treatment strategies.

Abstract
BACKGROUND Recurrent hepatitis C virus (HCV) infection following liver transplantation is associated with accelerated progression to graft failure and reduced patient survival. METHODS The Phase II, open-label SATURN study (NCT01938625) investigated the combination of simeprevir (SMV), daclatasvir (DCV), and ribavirin (RBV) administered for 24 weeks in 35 patients with recurrent HCV genotype (GT) 1b infection after orthotopic liver transplantation (OLT). RESULTS High rates of both on-treatment and sustained virologic response 12 weeks after end of treatment (SVR12) were achieved in patients who were either treatment-naïve or had failed post-OLT treatment with peginterferon and RBV. Overall, 91% of patients (32/35) achieved SVR12. The combination was generally well tolerated, with an adverse event profile consistent with that observed in previous clinical trials of SMV or DCV separately. Co-administration of SMV with cyclosporine resulted in significantly increased SMV plasma exposures, which was not the case with the co-administration of SMV with tacrolimus. Therefore, the concomitant use of SMV with cyclosporine is not recommended. CONCLUSION The interferon-free combination of SMV, DCV, and RBV administered for 24 weeks was shown to be effective and well tolerated in the treatment of post-OLT HCV GT1b-infected patients.

Abstract
BACKGROUND Some investigators maintain that a parathyroidectomy (PTX) performed for tertiary hyperparathyroidism may potentially cause graft malfunction or even loss of the transplanted kidney after the operation. The goal of this study was to determine if parathyroidectomy affects transplanted kidney function. METHODS The study group consisted of 48 renal graft recipients who underwent operation due to tertiary hyperparathyroidism. Thirty-nine subtotal parathyroidectomies and 9 more selective, less than subtotal parathyroidectomies were performed. The estimated glomerular filtration rate (eGFR) was calculated retrospectively on days 2 to 3 and 4 to 5 and at 1, 3, 6, 12, 24, and 36 months after PTX; these findings were compared with preoperative values. The cumulative graft survival rate in the postoperative period was assessed. RESULTS In the follow-up period, 4 of 48 patients returned to hemodialysis (after 1, 7, 22, and 57 months after PTX). In the first case, the patient had stopped taking the immunosuppressive drugs 1 month after PTX. Cumulative graft survival rate after PTX was 98.0% after 6 months, 96% after 12 months, and 93% after 2 and 3 years. The mean preoperative eGFR was 52 ± 17.15 mL/min/1.73 m(2), and the median was 48.28 mL/min/1.73 m(2). Overall and in the subtotal parathyroidectomy group, eGFR was significantly lower (P < .001) only on days 2 to 3. There were no differences between preoperative and postoperative eGFR values in the other follow-up periods. In the more selective, less than subtotal parathyroidectomy group, the decrease in eGFR values was nonsignificant compared with preoperative findings in the early postoperative period as well as in all follow-up periods. CONCLUSIONS In this study, PTX did not significantly impair transplanted kidney function, but in the early postoperative period, transient reductions in graft function did occur.

Abstract
Allelic variants of the MYH9 gene, encoding myosin nonmuscle heavy chain type IIA, have been shown to correlate with diminished glomerular filtration rates and end-stage kidney disease in individuals of Caucasian ancestry. Myosin nonmuscle heavy chain type IIA is expressed during development as well as in injured vessels and kidney structures. We hypothesized that MYH9 risk variants may correlate with kidney artery injury and dysfunctional healing, such as transplant renal artery stenosis (TRAS). Our study aimed at evaluating the association of MYH9 risk allelic variants (rs4821480, rs4821481, rs3752462, rs11089788, rs136211, rs5756168, rs2032487, and rs2239784) with TRAS, defined as >50% renal artery lumen reduction. Genotyping was performed with the use of custom Taqman genotyping assays on DNA samples (n = 295) from white deceased-donor kidney transplant recipients and genomic DNA from the corresponding donors. Statistical analysis was performed with the use of Kaplan-Meier estimates, log-rank tests, and proportional hazard Cox models. Recipients carrying TT in rs5756168 experienced diminished risk of TRAS (hazard ratio [HR], 0.31; P < .009), whereas organs carrying CC in rs3752462 were exposed to excessive TRAS risk (HR, 2.54; P < .047). In multivariate stepwise analysis TRAS was 10.9-fold increased in kidneys originating from rs3752462 CC, whereas the risk was decreased 3.45-fold (adjusted HR, 0.29) in recipients carrying rs5756168 TT (P < .007 and P < .033, respectively). Intracranial bleeding or trauma compared with other mechanisms of donor death diminished TRAS risk by 87% and 91%, respectively (P < .030 and P < .017). Our study is the first to identify genetic predisposition to transplant renal artery stenosis.

Abstract
BACKGROUND Malignancies will be a leading cause of mortality in renal transplant recipients in the next 20 years. Renal cell cancer (RCC) is the most common urologic cancer in kidney transplant recipients. The risk of RCC development in kidney transplant recipients is 15-100 times higher than in the general population. The purpose of the current retrospective study was to assess the frequency of nephrectomies performed because of renal tumors in the native kidneys in kidney transplant recipients in the Department of General and Transplantation Surgery at the Medical University of Warsaw between 2010 and 2014 year; the identification of kidney recipients diagnosed with RCC; and epidemiologic, clinical, and histopathological aspects associated with RCC. PATIENTS AND METHODS A total of 319 nephrectomies were performed in the Department of General and Transplantation Surgery at the Medical University of Warsaw between 2010 and 2014 year. Renal tumors were diagnosed in 25 renal transplant recipients. RESULTS Among malignant tumors, 13 cases of RCC and 1 case of post-transplant lymphoproliferative disorder (PTLD) were observed. There was no significant difference between age and duration of pretransplantation dialysis in patients with RCC and patients with benign tumors (P = .14 and P = .91, respectively). Body mass index was significantly higher in patients with RCC than in patients with benign tumors (P = .04). CONCLUSIONS Renal cell cancer is more common among male kidney recipients. There is a good Polish screening system allowing detection of kidney cancer in native kidney. We recommend performing periodic screening for kidney cancers to obtain an early diagnosis.

Abstract
INTRODUCTION The aim of this study was to investigate risk factors for urinary tract infections (UTI), the causative organisms of UTI and also their management and treatment. In addition, we evaluated the effects of UTI on renal graft function. METHODS This analysis included 107 kidney transplant recipients (64% women) with a diagnosis of UTIs confirmed by positive results on urine culture. Type of pathogens, sensitivity to drugs, risk factors for infection, incidence of urosepsis, hospitalization period, treatment methods, and recurrence rates were analyzed. Statistical analysis was performed by using Pearson's χ(2) test, Yates' χ(2) test, the Student t test, Welch's t test, the Mann-Whitney U test, Fisher's exact test, and the Shapiro-Wilk normality test. RESULTS The most common species isolated from urine samples included Escherichia coli (42%), Klebsiella pneumoniae (15%), and Enterococcus faecalis (10%). The percentage of multidrug-resistant strains was 31%, and urosepsis was diagnosed in 16% of patients. Recurrences developed in 76% of infected patients. Bricker ureterointestinal anastomosis was performed in 11% of patients. Risk factors for severe infections included: pre-transplantation urinary tract surgery (P = .02), double-J stent insertion (more common in men) during KTx (N = 34; 32%), (P = .021), reoperations following transplantation (P = .36), elevated tacrolimus levels at the time of infection (P = .024). Severe infections were diagnosed in patients with lower eGFRs, were associated with a need for longer hospitalization (P = .04) and escalation of antibacterial treatment. Carbapenems were used in 22 patients (20.5%). CONCLUSIONS UTIs were more common in women, in patients with impaired function of the kidney transplant, and in those with a history of urinary tract interventions. Severe infections were associated with a risk of urosepsis, longer hospitalization, and a need for escalation of antibiotic treatment.

Abstract
AIM A major problem for the transplant society is a shortage of organs for transplantation compared with the number of patients on the waiting list. This study aimed to assess the results of the transplantation of kidneys procured from older donors. PATIENTS AND METHODS A total of 27 kidneys procured from donors age 70 years or older were transplanted between January 1, 2010, and April 25, 2015. These represented only 4.1% of the 657 kidneys transplanted from deceased donors during this period at the same center. RESULTS Delayed graft function (DGF) in the recipients of kidneys procured from donors age 70 or older occurred in 46.1% of patients, whereas the recipients of kidneys from younger donors showed DGF at a frequency of 32.7% (P = NS). The annual and 3-year survival rates of kidneys in the study group were 85% and 80%, respectively, and in the control group were 92.5% and 88.6%, respectively (P = NS). According to the Polish National Organ Procurement Organization (Poltransplant), the annual survival rate of a transplanted kidney in Poland stands at 89%, whereas the 3-year survival rate is 82%. We detected no significant posttransplantation differences in the serum creatinine concentration and in the estimated glomerular filtration rate between the study and control groups. The donor age and donor creatinine were the variables independently associated with DGF. CONCLUSIONS The results of transplantation of kidneys from elderly donors were comparable to those of transplantation from younger donors. Kidneys harvested from elderly donors should be used for a transplant after a preliminary assessment.

Abstract
BACKGROUND Population aging and shortage of organs for transplantation result in increasing numbers of kidneys retrieved from elderly donors. The aim of this study was to analyze donation of kidneys from donors after brain death (DBD) over the age of 60 years (≥60), comorbidities that affect decisions on retrieval, and early results of kidney transplantation. METHODS Ninety-six potential DBD ≥60 and 309 aged 40-59 years (40-59) reported in Upper Silesia, Poland, from 2004 to 2013 were enrolled in the study. RESULTS DBD >60 presented a higher rate of coexisting hypertension (53% vs 34%), limb ischemia (10% vs 1%), and past stroke (6% vs 1%) compared with DBD 40-59 (P < .05), but no differences were observed in serum creatinine concentration (85 vs 84 μmol/L), coexisting coronary disease (14% vs 6%), or diabetes (10% vs 4%). The decision of withdrawal from retrieval was more frequent in DBD ≥60 (16% vs 7%; P < .05). Twelve months after kidney transplantation, serum creatinine concentration was higher in recipients of kidneys from DBD ≥60 compared with DBD 40-59 (169 vs 138 μmol/L; P < .001). The survivals of recipients (93% vs 95%) and kidney grafts (90% vs 93%) as well as rates of proteinuria >1.0 g/24 h (6% vs 2%) did not differ between the groups. CONCLUSIONS A higher rate of comorbidities in potential kidney DBD ≥60 results in a lower retrieval rate in these donors. The function of kidneys harvested from DBD ≥60 12 months after transplantation is worse than those from DBD 40-59, but still acceptable.

Abstract
INTRODUCTION Health benefits of a living-donor kidney transplantation are numerous and well known. There is, however, a dearth of knowledge on postoperative quality of life among the living-donor (LD) compared to deceased-donor (DD) transplant recipients. MATERIALS AND METHODS The study involved 89 patients after renal transplantation: 48 from LDs and 41 from DDs. Interview data indirectly indicated the patients' health, whereas physiological parameters directly pinpointed the patients' health and the graft function. All study participants completed questionnaires to measure quality of life and the specificity of emotional and cognitive functioning. RESULTS LD kidney recipients were younger than DD recipients (40 years vs. 49 years). LD and DD transplantation patients were similar in health status assessed by indirect methods (data from an interview) and direct methods (laboratory tests results). They, however, differed in their psychosocial functioning. LD patients had a greater sense of happiness (P < .01) and of self-efficacy (P = .07). Moreover, these patients were more actively involved in their social lives (P < .02) and were more satisfied with their social relationships (P = .07). LD recipients also had a higher quality of life in terms of mental functioning (P < .01) and satisfaction with their environments (P < .01). Additionally, there were significant correlations between quality of life and the quality of cognitive and emotional functioning in the group of LD recipients. The perceived impact of health on physical and professional activity and daily routines was similar in LD and DD groups. CONCLUSIONS LD post-transplantation patients may derive greater psychosocial benefits from this form of treatment. This effect is not dependent on somatic parameters (comparable data from an interview and laboratory tests results). This study suggests that patients should be assisted by a multidisciplinary healthcare team, and receive continuous support from relatives during the post-transplantation adaptation process. This facilitates the patients' postoperative quality of life.

Abstract
BACKGROUND Assessment of the dynamics and degree of liver fibrosis in patients after liver transplantation is a basic element in the process of determining transplant survival prognosis. It allows planning and early initiation of prophylaxis or treatment, which translates into increased chances of preventing cirrhosis and of long-term optimal function of the graft. The aim of this study was to compare the results of biopsy and dynamic elastography in diagnostics of transplanted liver fibrosis, as well as determination of the stiffness cut-off point for assessment of significant fibrosis. PATIENTS AND METHODS The study included 36 patients who had undergone liver transplantation due to cirrhosis in the course of hepatitis C virus (HVC) infection. Fibrosis was assessed in bioptates according to the METAVIR score (F0-F4). Elastography was performed using FibroScan; receiver operating characteristic curve analysis was used to identify the cut-off point for significant fibrosis (≥F2). RESULTS The median stiffness in kPa for the whole group F0-F4 was 6.3 (range 3.4-29.9); for ≥F2 it was 6.9 (3.4-29.9), whereas for F0-F1 it was 4.4 (3.5-8.0). It was demonstrated that the value of 4.7 kPa in elastography is a statistically significant cut-off point for differentiation between the groups F0-F1 and F2-F4 (sensitivity: 93%, specificity: 57%, positive predictive value: 90%, negative predictive value: 66%), area under the receiver operating characteristic curve: 0.746 (95% confidence interval: 0.53-0.95, P < .05). CONCLUSIONS Elastography is a promising tool for noninvasive assessment of significant liver fibrosis in patients after transplantation due to cirrhosis in the course of hepatitis C; it allows reduction in the number of biopsies performed.

Abstract
INTRODUCTION Antibodies against donor human leukocyte antigens (HLAs) play a significant role in the pathogenesis of antibody‑mediated rejection, although their relevance during the late posttransplant period is unknown. A non‑HLA polymorphic antigenic system, like major histocompatibility class I chain‑related antigen A (MICA), might be another target for antibody responses involved in rejection. OBJECTIVES We conducted a 7‑year prospective study to determine the effect of positivity for anti‑HLA and anti‑MICA antibodies on kidney graft survival. PATIENTS AND METHODS A random blood sample was collected from 457 kidney recipients during a regular outpatient visit. Patients who were less than 6 months after transplantation were excluded. Evaluation of anti‑HLA (classes I and II) and anti-MICA antibodies was performed with the use of Luminex assays. An outpatient registry was used to monitor kidney function during a 7‑year follow‑up. RESULTS A total of 147 patients (32%) had anti‑HLA and 88 patients (19%) had anti‑MICA antibodies. Graft failure occurred in 67 anti‑HLA‑positive individuals (46%) as compared to 81 anti‑HLA‑negative ones (26%) (P <0.05), and in 30 anti‑MICA‑positive individuals (34%) as compared to 118 anti‑MICA‑negative ones (32%) (P = 0.52). Anti‑HLA antibodies were associated with increased incidence of graft failure: it was reported in 200 patients with an estimated glomerular filtration rate of more than 30 ml/min/1.73 m2 body surface area more than 5 years after transplantation (P <0.005). CONCLUSIONS Anti‑HLA, but not anti‑MICA, antibodies in randomly obtained blood samples were the significant predictor of late kidney graft failure and could be a low‑cost method enabling identification of patients requiring an individualized posttransplant approach. The results of our study provide an additional rationale for investigating immune biomarkers in certain diseases.

Abstract
BACKGROUND There is a need for early identification of children with immunoglobulin A nephropathy (IgAN) at risk of progression of kidney disease. METHODS Data on 261 young patients [age <23 years; mean follow-up of 4.9 (range 2.5-8.1) years] enrolled in VALIGA, a study designed to validate the Oxford Classification of IgAN, were assessed. Renal biopsies were scored for the presence of mesangial hypercellularity (M1), endocapillary hypercellularity (E1), segmental glomerulosclerosis (S1), tubular atrophy/interstitial fibrosis (T1-2) (MEST score) and crescents (C1). Progression was assessed as end stage renal disease and/or a 50 % loss of estimated glomerular filtration rate (eGFR) (combined endpoint) as well as the rate of renal function decline (slope of eGFR). Cox regression and tree classification binary models were used and compared. RESULTS In this cohort of 261 subjects aged <23 years, Cox analysis validated the MEST M, S and T scores for predicting survival to the combined endpoint but failed to prove that these scores had predictive value in the sub-group of 174 children aged <18 years. The regression tree classification indicated that patients with M1 were at risk of developing higher time-averaged proteinuria (p < 0.0001) and the combined endpoint (p < 0.001). An initial proteinuria of ≥0.4 g/day/1.73 m2 and an eGFR of <90 ml/min/1.73 m2 were determined to be risk factors in subjects with M0. Children aged <16 years with M0 and well-preserved eGFR (>90 ml/min/1.73 m2) at presentation had a significantly high probability of proteinuria remission during follow-up and a higher remission rate following treatment with corticosteroid and/or immunosuppressive therapy. CONCLUSION This new statistical approach has identified clinical and histological risk factors associated with outcome in children and young adults with IgAN.

Abstract
BACKGROUND Cardiovascular (CV) complications are the major cause of death in kidney transplant (KT) patients. METHODS During a 3-year follow-up, 112 KT recipients, from living (LD KTRs; n = 54), and deceased (DD KTRs; n = 58) donors, were assessed for 10-year risk of fatal CV events with the use of the Heartscore tool (www.heartscore.org). In post-KT months 6, 12, and 36, current and optimum (target) CV risks (CVRs) were estimated. RESULTS Current risk was lower in the LD KTRs and remained stable. In DD KTRs, the risk was at the highest level in months 6 and 12 of follow-up and decreased in month 36. Change in CVR, ie, the difference between the current and target risk, was the highest in DD KTRs in month 36 of follow-up (P = .014). In the increased-CVR group, recipients were older (P < .01), primarily male (P = .08), and more frequently smokers (P < .01) and had a higher systolic blood pressure (P < .05) despite taking more hypotensive medicines (P < .01), and had higher total cholesterol (P < .01) and low-density lipoprotein (P < .01) levels. In this group, body mass index (BMI) was higher (P < .01) and metabolic syndrome was diagnosed significantly more often (P < .01). The high-risk group (estimated CVR, ≥5) was different also in longer durations of pre-transplantation dialysis (P < .05) and higher rates of CV episodes before transplantation (P < .05). In logistic regression, higher BMI and lower estimated glomerular filtration rate (eGFR) were the parameters strongly correlated with higher CVR. CONCLUSIONS Mean CVR applicable to all kidney transplant recipients was stable throughout the follow-up. Changes in the risk affected mainly DD KTRs. In months 6 and 12, CVR was the highest in this group and was substantially reduced in the 3rd year of follow-up, probably owing to medical interventions. In the high-CVR group, impaired function of the transplanted kidney was recorded. CVR scores in patients with renal conditions and after kidney transplantation should additionally account for eGFR.

Abstract
BACKGROUND Simultaneous pancreas and kidney transplantation (SPKTx) is the most commonly performed multiorgan transplantation procedure worldwide. Transplanted organs are the main source of complication; however, some postoperative complications are not directly related to the pancreatic or renal grafts. The goal of this study was to evaluate the prevalence, type, and severity of postoperative complications not related to transplanted kidney or pancreas among SPKTx recipients. METHODS Complications unrelated to transplanted pancreas and kidneys among 112 SPKTx recipients were analyzed. The cumulative freedom from general surgical complications was assessed, and it was compared with cumulative freedom from complications related to kidney and pancreatic grafts. Severity of complications was classified according to a modified Clavien-Dindo scale. RESULTS The general surgery complication rate was 22.2%. Cumulative freedom from general surgical complications at days 60 and 90 after transplantation was 0.89 and 0.87, respectively. Cumulative freedom from general surgical complications was comparable with cumulative freedom from complications related to kidney grafts but significantly higher than cumulative freedom from complications related to pancreatic grafts (log-rank test, P < .001). The rates for grades of severity II, IIIa, IIIb, and IVb were 19.4%, 9.7%, 64.5%, and 6.4%, respectively. The most frequent cause of complications was intra-abdominal hematoma or abscess (25.8%). CONCLUSIONS The general surgical complication rate was comparable to the rate of complications originating from the renal grafts but significantly lower than the complication rate related to the transplanted pancreas. The incidence of general surgical complications could be defined as moderate, and the severity of this type of complication was low.

Abstract
BACKGROUND We report 2 cases of polyomavirus-associated nephropathy (PyVAN) emerging within the initial 8 posttransplant weeks. These cases were characterized by intraepithelial BK virus replication without typical nuclear inclusions in epithelial cells. METHODS AND RESULTS A 70-year-old male recipient of a cadaveric kidney transplant had experienced unsatisfying graft function since the time of transplantation (Tx). One month after Tx, results of a graft biopsy revealed mild tubulointerstitial inflammation. No intraepithelial nuclear inclusions suggestive of viral infection were present at that time. The patient received intravenous methylprednisolone, and the dosage of tacrolimus was increased. Due to a further drop in the glomerular filtration rate, a subsequent kidney biopsy was performed during posttransplant week 10, which revealed lesions typical of PyVAN. Retrospectively performed SV40 staining revealed that intragraft polyomavirus replication was already present on posttransplant day 30. Basic immunosuppression reduction and ciprofloxacin administration were followed by BK viremia elimination, stabilization of graft function, and resolution of PyVAN. In another patient, a 62-year-old male recipient of a cadaveric renal graft, BK viremia was monitored from the time of Tx. Two months after Tx, the patient was found to have a BK viral load of 6 × 4 log(10)/mL. Results of the graft biopsy revealed fully preserved tubular epithelium, but SV40 staining was positive in some of these cells. After basic immunosuppression reduction and introduction of ciprofloxacin, the BK viral load dropped to 1 × log(10)/mL with graft function stabilization. CONCLUSIONS PyVAN may emerge as early as 4 weeks after Tx, with near-normal or acute rejection-like graft morphology. The early monitoring of plasma BK viral load, as well as SV40 staining, avoids misdiagnosis of this severe posttransplant complication.

Abstract
OBJECTIVE Simultaneous pancreas and kidney transplantation (spktx) is the multiorgan transplantation. Thus various complications originated from transplanted organs and the complications that are not directly related to pancreatic or renal grafts could be developed at the same recipient. AIM The aim of this study is to explore whether there is a correlation between the severity of complications originated from transplanted pancreas, transplanted kidney and general surgical complication developed at the same spktx recipient. METHODS Complications which developed among 112 spktx recipients were divided into three groups: related to the pancreatic graft (PTXc), to the renal graft (KTXc) and the general surgical complication (GNc). Severity of postoperative complications using modified Dindo-Clavien scale recipients was evaluated for each group. The correlation of severity of coexisting complications from different complication groups was analyzed. RESULTS There were 22 recipients who developed the coexistence of complication between different complication groups. Complication originated from two and three complication groups developed 15 (68.2%) and 7 (31.8%) patients, respectively. There was not found correlation of the complication severity between: KTXc and GNc group, GNc and PTXc group, KTXc and PTXc group. The correlation (r = 0.84) of complication severity in recipients who developed concurrently complication from transplanted kidney, transplanted pancreas and general surgery complication was found. CONCLUSION The modified Dindo-Clavien scale is an useful methodology for the correlation description of complication severity in complex multiorgan transplantation such is spktx, especially when the complications originated from different, potentially independent from the pathophysiological point of view, sources.

Abstract
Early diagnosis of invasive pulmonary mycoses in immunocompromised patients is a major determinant of effective treatment. However, making a reliable diagnosis is challenging and often requires transbronchial or even surgical lung biopsy. We provide evidence that endobronchial ultrasound-guided transbronchial needle aspiration may be an attractive, less invasive diagnostic method. Endobronchial ultrasound-guided transbronchial needle aspiration was not only a diagnostic clue in the presented kidney transplant recipient with invasive pulmonary mycosis but was useful in assessment of treatment efficacy.

Abstract
BACKGROUND Recurrent HCV infection following liver transplantation is a common problem, and usually has a more aggressive course than primary infection. The aim of the paper was to present nursing problems in the care of a 22-year-old female patient after liver transplantation (Ltx) with a rapid recurrence of HCV infection shortly after Ltx. CASE REPORT Ltx was performed 22 July 2012 due to chronic cirrhosis secondary to HCV infection with viremia (HCV PCR 3.5×107 IU/mL). Graft function worsened 14 days following transplantation. Acute cholestatic hepatitis related to HCV reinfection was diagnosed based on biopsy. During a period of 20 months the patient received 3 different antiviral treatment regimens, beginning with a dual therapy (Interferon and Ribavirin), followed by the inclusion of Telaprevir, then Daclatasvir; however, these treatments were not successful. The fourth-line regimen with sofosbuvir (EU medical experiment) led to viremia elimination (HCV PCR) after 5 weeks of treatment. However, hepatic failure stabilization was unsuccessful, there was an increase in encephalopathy, and the MELD score was 25. Therefore, the patient underwent liver retransplantation. In the post-transplantation period, the patient was in good condition, with no viremia. CONCLUSIONS The most common nursing problems in the care of the patient were associated with the diagnostic process, therapies used (including experimental treatment), and progressive liver failure. The therapeutic success should be attributed to the intensive supervision and monitoring of viremia, immediate inclusion of adequate treatment methods, adequate patient preparation for diagnostic tests, and careful care after diagnostics, as well as psychological support and education.
