Abstract
INTRODUCTION Cirrhosis related to hepatitis C virus (HCV) and hepatitis B virus (HBV) infection is the most frequent indication for liver transplantation worldwide. Progress in prophylaxis of posttransplant HBV recurrence has led to major improvements in long-term outcomes of patients after liver transplantation. Conversely, impaired posttransplant survival of patients with HCV infection was reported in several studies, mainly due to recurrence of viral infection. The purpose of this study was to compare long-term results of liver transplantation between patients with HBV monoinfection, HCV monoinfection and HBV/HCV coinfection. MATERIAL AND METHODS A total of 1090 liver transplantations were performed in the Department of General, Transplant and Liver Surgery in cooperation with the Department of Immunology, Internal Medicine, and Transplantology at the Transplantation Institute Medical University of Warsaw between December 1994 and May 2012. After exclusion of patients with cirrhosis of non-viral etiology, patients with malignant tumors, and patients with acute liver failure, the final study cohort comprised 209 patients with HBV (HBV+/HCV- subgroup; n = 56) or HCV (HBV-/HCV+ subgroup; n = 119) monoinfection or HBV/HCV coinfection (HBV+/HCV+; n = 34). These subgroups of patients were compared in terms of long-term results of transplantations, defined by 5-year patient and 5-year graft survival estimates. RESULTS Overall and graft survival rates after 5-years for the whole study cohort were 74.5% and 72.6%, respectively. Five-year overall survival was 70.4% for patients within the HBV+/HCV- subgroup, 77.8% for patients within the HBV-/HCV+ subgroup, and 68.5% for patients within the HBV+/HCV+ subgroup. The corresponding rates of graft survival were 67.0%, 76.3%, and 68.5% for patients within the HBV+/HCV-, HBV-/ HCV+, and HBV+/HCV+ subgroups, respectively. Observed differences were non-significant, both in terms of overall (p = 0.472) and graft (p = 0.461) survival rates. CONCLUSIONS Both overall and graft survival rates after liver transplantations performed in the Department of General, Transplant and Liver Surgery in cooperation with the Department of Immunology, Internal Medicine, and Transplantology at the Transplantation Institute Medical University of Warsaw in patients with HBV and HCV infection are comparable to those reported by other European and American centers. In contrast to other studies, obtained results do not confirm the negative impact of HCV infection on long-term outcomes of patients.

Abstract
The purpose of this work is a presentation of cases of persons with Klinefelter Syndrome where, most probably--as a result of testosterone supplementation therapy, some aggressive behaviours occurred requiring implementation of pharmacotherapy and psychiatric hospitalisation. The authors contemplate adequacy of standard hormone treatment where the main purpose is to improve the quality of life of the karyotype 47, XXY patients described. The article has been enhanced by a theoretical introduction into the basic subject which is the Klinefelter Syndrome.

Abstract
BACKGROUND The activation status of intestinal immune system cells is much higher than that of analogous peripheral cells. Increased serum concentrations of proinflammatory cytokines have been reported in various pathologic conditions; however, the source of these mediators has not been elucidated. OBJECTIVE To assess the role of the human intestine and its lymphatic system in production of growth factors and proinflammatory cytokines. MATERIAL AND METHODS Twenty liver transplant recipients and 20 donors were included in the study. Blood samples were obtained from the artery supplying the intestine, the portal vein, and a peripheral vein during liver harvesting in donors and after transplantation in recipients. An enzyme-linked immunosorbent assay was used to assess serum concentrations of IL-6, tumor necrosis factor-alpha (TNF-alpha), transforming growth factor-beta (TGF-beta), and hepatocyte growth factor (HGF). RESULTS In transplant recipients, IL-6 concentration in arterial blood was lower than that in portal blood (P < .049), whereas in donors, there was no significant difference in these concentrations. Neither recipients nor donors demonstrated significant differences in arterial or portal blood concentrations of TNF-alpha, TGF-beta, or HGF. CONCLUSIONS In healthy human beings, the intestine is not a substantial source of IL-6, TNF-alpha, TGF-beta, or HGF. However, in patients with liver cirrhosis, the intestine is an important source of IL-6 but not of the other studied growth factors and cytokines.

Abstract
BACKGROUND Patients undergoing liver transplantation (ltx) for hepatitis B-related liver disease are prone to recurrence. Historically, ltx has been associated with aggressive reinfection and poor survival results. The mainstay of prophylaxis has been passive immunotherapy with hepatitis B immune globulin(HBIG). Antiviral prophylaxis with lamivudine appears to reduce hepatitis B virus (HBV)infection after liver transplantation. However, HBV recurrence remains common. This study retrospectively evaluated a single center's experience with cohort of patients who underwent ltx for HBV-related chronic and acute liver disease. We examined the effect of a combined of intravenous HBIG and lamivudine viral prophylactic therapy on HBV recurrence and the outcome of ltx. MATERIAL/METHODS Eighteen patients underwent transplantation for HBV liver disease at our center. Before ltx all patients were HBsAg positive and 3 were HBV DNA positive. HBV recurrence was defined by HBsAg seropositivity after ltx. HBIG monotherapy was used in 2 (15%) patients, lamivudine monotherapy in 4 (31%), and lamivudine and HBIG combination in 7 (54%). Hepatocellular carcinoma was present in 1 patients. Maintenance immunosuppression regimens consisted of either a cyclosporine- or tacrolimus-based drug regimen. RESULTS Overall 1-year and 3-years patient survival rates were 60% and 60%, respectively, and 1-year and 3-years graft survival was 60% and 60% respectively. Among 7 patients receiving receiving combination HBIG and lamivudine, one patient died. He was retransplanted 9 months after first transplantation secondary to biliary complication caused by late hepatic artery thrombosis. Of the 6 surviving patients, 4 patients currently have normal allograft function. Allograft dysfunction developed in two patients because of ischemic biliary strictures. Among seven patients, who received HBIG and lamivudine, one did not receive proper administration of the prophylactic regimen and graft became infected. Serologic HBV recurrence was diagnosed after 9 months after transplantation. CONCLUSIONS Liver transplantation for HBV under combination viral prophylaxis results in good survival rates. A good outcome is possible after liver transplantation for HBV liver disease using HBIG dosed by pharmacokinetic parameters in combination with lamivudine. Viral prophylactic therapy has effectively reduced HBV recurrence and prolonged survival outcome.

Abstract
As more effective therapies prolong the lives of patients with cystic fibrosis, there are now more patients in this population diagnosed with liver diseases. Secondary biliary cirrhosis is not a rare complication of mucoviscidosis. It is diagnosed in 20% of patients with mucoviscidosis; in 2% it is accompanied by portal hypertension. On average patients with portal hypertension and its complications are 12 years old. Liver transplantation is an accepted method of treatment for children with cystic fibrosis and portal hypertension. It eliminates the cause of the portal hypertension, decreases life-threatening medical conditions, and improves their nutritional status and quality of life. Despite immunosuppressive treatment they do not seem to beat increased risk of upper respiratory tract infections. On the contrary improved respiratory function and status are generally observed. We present our first case of orthotopic liver transplantation performed in a 29-year-old man with cystic fibrosis. The donor was a 42-year-old woman who died of a ruptured cerebral aneurysm. The surgery was performed in September 2004. The patient received immunosuppression based on steroids, basiliximab, tacrolimus, and mycophenolic acid due to renal insufficiency. Antibiotic (meropenem) and antiviral prophylaxis (gancyclovir) were used. A 6-month period of observation confirmed the clinical data from the pediatric population-a good prognosis with improved nutritional status, respiratory function, and quality of life.

Abstract
INTRODUCTION Hepatitis C virus (HCV) recurrence is almost universal in patients after liver transplantation. The diagnosis of reinfection is more difficult than that of a primary process, as shown by our pathomorphologic analysis of cases of HCV recurrence. MATERIAL During 5.5 years, 240 liver biopsies included 54 obtained from liver transplant recipients with primary HCV infections, among whom 26 (56.5%) had clinical signs and symptoms of hepatitis. Nineteen patients from this population underwent 30 liver biopsies. In addition, seven biopsies were performed in five patients without clinical signs of reinfection. RESULTS In 44.2% of patients with HCV recurrence and 15% without reinfection, the intensity of the primary process in the native livers was assessed as high. Reinfection was found in all patients with liver carcinoma and 67% with hepatocyte dysplasia. Histologic signs of infection were estimated as minimal (n = 4), mild (n = 19), or moderate (n = 4). In five patients with reinfections and one without recurrence, histologic manifestations of acute rejection were also observed. In conclusion, HCV was the indication for liver transplantation in 22.4% cases. Clinical manifestation of recurrence was found in 56.5% of the patients, who tended to be older than those without disease recurrence. Upon microscopy, lobular lesions predominated over the portal changes. Factors predisposing to HCV recurrence were coexistence of other liver disorders, a high intensity of the inflammatory process, hepatocyte dysplasia, and/or hepatocellular carcinoma in the native liver and acute rejection episodes.

Abstract
Posttransplant lymphoproliferative disorder (PTLD) is a well-known complication of both solid organ and bone marrow transplantation. It includes a wide spectrum of proliferative changes ranging from reactive hyperplasia, borderline lesions to malignant lymphomas. PTLD develops in 1% to 10% of transplant recipients. We present 10 cases of PTLD. Five developed after renal, four after liver, and one after heart transplantation. Among the early lesions, we diagnosed two reactive plasmacytic hyperplasias; one infectious mononucleosis-like PTLD; one polymorphic lesion; and one "mixed" case of plasmacytic hyperplasia in one tonsil with a polymorphic PTLD in the second one. Among the lymphomas, we observed three diffuse large B-cell lymphoma (DLBCL); one mantle lymphoma; and one Hodgkin lymphoma-like PTLD. The morphological pictures of six PTLD cases were typical and posed no diagnostic problems. In the one case of plasmacytic hyperplasia, the lymph node morphology was atypical with atrophy of lymphoid components accompanying plasma cell proliferation. Contrary to a good prognosis of early, reactive PTLD, this patient experienced a rapid course and succumbed to sepsis. The most difficult case was a rare Hodgkin lymphoma-like PTLD, which was diagnosed only by a bone marrow biopsy. Because of its noncharacteristic immunophenotype, it was primarily diagnosed as an anaplastic lymphoma of the T-cell type. After additional immunohistochemical studies (BOB and OCT2), we established the final diagnosis of Hodgkin lymphoma-like PTLD. Due to the increasing number of organ transplantations, doctors of various specialties may encounter PTLD.

Abstract
INTRODUCTION Acute hepatic allograft rejection remains an important problem following liver transplantation. Liver biopsy specimens show a combination of characteristic changes, first observed by Snover as a diagnostic triad: portal inflammation, bile duct damage, and central or portal vein endothelial inflammation (endothelitis or endothelialitis). The aim of this study was to describe our histopathological assessment of liver transplants. MATERIALS AND METHODS In the period between September 2000 and June 2004, we evaluated 150 liver biopsy specimens from 105 liver recipients. RESULTS Acute rejection was diagnosed in 26.6% of liver biopsies taken from 31.4% patients who demonstrated clinical symptoms of liver damage. In 90% of cases the rejection was described as minimal or mild, and in 10% as moderate. There was no episode of severe acute rejection. Only four biopsies (10%) showed nothing but Snover triad changes. In 9 (22.5%) cases only acute rejection was diagnosed; the remaining showed in addition to acute rejection the possibility of other concomitant pathologies: viral infection in 15 cases (37.5%), biliary flow obstruction in 11 cases (28.5%), functional cholestasis in two cases (5%), and ischemic complications in three cases (7.5%). CONCLUSIONS Histologically confirmed acute rejection episodes were diagnosed in 14.9% liver recipients. Liver biopsy specimens, aside from Snover triad features, often showed other unspecific morphological changes. Differentiation of acute rejection from other accompanying diseases is sometimes difficult, requiring precise clinical data and pathologist experience.

Abstract
INTRODUCTION The aim of this study was an economic evaluation of three sirolimus (SRL)-based regimens in the first 2 years after renal transplantation. MATERIALS AND METHODS The three SRL-based immunosuppressive regimens in renal transplant patients between June 2000 and September 2002 were: (1) SRL + steroids + cyclosporine (CsA) permanently; (2) SRL + steroids + tacrolimus (Tac); and (3) SRL + steroids + CsA, with CsA discontinuation at 3 months posttransplant. Ten patients were included in each group in an intent-to-treat analysis. Cost was calculated according to the hospital price list and recast into euros (EUR) with a 5% discount rate. RESULTS The number of patients free of an acute rejection episode during 2 years posttransplant were 6, 8, and 5, with 2-year graft and patient survivals of 9, 10, and 9 for regimens 1, 2, and 3, respectively. As differences in clinical effects were not statistically significant, cost analysis was appropriate instead of cost-effectiveness analysis. The mean cost of the 2-year treatment was 15,759 EUR; 25,593 EUR; and 21,197 EUR per patient for regimens 1, 2, and 3, respectively. Sensitivity analysis for the main variables confirmed that the results were not dependent on changes in costs. CONCLUSIONS Regimen 1 was the most economical immunosuppressive therapy during the 2 years after kidney transplantation. Studies on a larger group of longer observation would be more useful for clinical analysis.

Abstract
Pregnancies in women after liver transplantation are considered high risk due to the greater rate of complications observed in immunosuppressed graft recipients. We report successful outcomes of four high-risk pregnancies in female liver transplant recipients on tacrolimus-based immunosuppression. The patients, aged 23 to 32 years, at the time of conception were 12 to 59 months from transplantation (mean 30 months). Preterm labor was the most important pregnancy complication observed in these patients. One episode of acute graft rejection was observed. A variable demand for tacrolimus was noted during pregnancy. Despite complications all four pregnancies were successful. The mean gestational age at delivery was 34.4 weeks. The birth weight of the newborns varied from 1410 to 3490 g (mean 2303 g) and the mean Apgar score was 8. No structural malformations or early complications were observed in the newborns. Excluding the patient with acute rejection, the remaining three cases showed all liver parameters to remain stable.

Abstract
AIM According to statistics, women constitute one-third of all liver recipients and approximately 75% of female recipients are of reproductive age. Successful liver transplantation in these patients results in the restoration of menstrual function and fertility. The aim of this study was to assess the course of pregnancy and delivery in liver-transplanted women. MATERIALS AND METHODS We retrospectively analyzed data of 138 liver-transplanted women, aged from 18 to 63 years, who underwent regular gynecological evaluations. Among 77 patients of reproductive age, 11 women conceived and delivered babies. RESULTS All patients have successfully delivered. The mean gestation age at delivery was 36.5 weeks. All neonates were delivered in a good state with no congenital abnormalities. Common pregnancy complications were preterm birth, anemia, intrahepatic cholestasis, and infection. In 1 case, graft rejection was observed due to willful discontinuation of immunosuppressive therapy. Two spontaneous vaginal deliveries and 9 caesarean sections were performed. All caesarean sections were performed for obstetrical indications: fetal intrauterine asphyxia (n = 4), breech presentation (n = 2), threatening intrauterine infection (n = 2), and preterm twin delivery (n = 1). CONCLUSION High-risk pregnancies in liver-transplanted women are generally associated with good outcomes, although an increased rate of preterm labor, intrauterine infections, anemia, and cholestasis were observed. Pregnancy did not seem to impair graft function or accelerate rejection in patients receiving immunosuppressive therapy.

Abstract
The aim of the study was to test the diagnostic accuracy of several serological assays for the diagnosis of tuberculosis (TB) in the Polish population. ELISA based assays detecting: 38 kDa+LAM - MycoM, MycoA and MycoG, 38 kDa - Pathozyme TB complex, 38 kDa+16 kDa - Pathozyme TB complex plus were used. The humoral immune response was analyzed in a group of 319 TB patients (289 adults and 30 children) and in a control group consisting of 66 sarcoidosis cases, 16 cases of mycobacterial infections other than tuberculosis, 35 lung cancer patients, and 70 healthy volunteers. Among the TB patients, there were 267 cases of pulmonary TB and 52 cases of extrapulmonary TB. Sensitivity varied between 32% (IgM) and 63% (IgA) and increased in culture positive tuberculosis and in chronic cases. Specificity was the highest for the tests based on recombinant antibodies (98%). Sensitivity of the IgG test in extrapulmonary TB was comparable with that in pulmonary TB. Overall, sensitivity of the examined tests was lower in children than in adults, but it varied depending on the age and phase of the disease. We conclude that the ELISA-based tests may be a useful tool for improving the diagnosis of TB, especially in adults and in those countries where the prevalence of culture positive and chronic cases is high.

Abstract
The so-called learning factor has been disregarded for many years in analyzing the causes of surgical complications and post-operative mortality; it is also the case for OLT. In our center until April 2003, 209 OLT were performed in 196 patients. We evaluated the impact of experience of the transplantation team on the outcomes of liver transplantation. Thirty-four patients died (mortality rate, 16%) and 1-year survival rate, 64%. Mortality rates varied during different periods of observation due to increasing experience of the transplantation team. The causes of mortality were assessed for a series of 34 patients: it was 75% at the beginning of transplantation procedures while recent deaths have not recently exceeded 10% of cases.

Abstract
The liver transplantation (ltx.) is currently the only efficient treatment of the diseases which lead to the end stage liver failure. The proper time to perform the operation and the evaluation of the survival time, with or without transplantation, are the most important aspects of qualifications to the liver transplantation. There are no specific criteria of patient qualification for liver transplantation and there are no objective quantitative liver function tests. There were created many prognostic models for evaluation patients with chronic liver diseases. Some of them, the most popular, are presented in this article. We assume, that probability of one year survival less than 90% is the indication for ltx. However, the most important is total evaluation of clinical condition of the patient with liver failure. Such a complicated problem like qualification patients for ltx. needs to be solved by a team of experts from different medical specializations.

Abstract
Autoimmune hepatis along with primary biliary cirrhosis, primary sclerosing cholagitis and some other not classified primary hepatobiliary pathologies belong to the group of liver diseases which are believed to be caused by autoimmune reactions. The primary causes of those pathological states remain unknown. However, thanks to the recent studies in immunogenetics and on autoantigens, progress has been made in understanding the mechanisms underlying these pathologies. The results of these studies are criteria of diagnosis and treatment of those diseases. In spite of some beneficial results of immunosuppressive treatment of AIH, the disease in some cases progresses and those states are one of the classical indications for allogenic liver transplantation.

Abstract
Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) belong to the group of liver diseases which are believed to be caused by autoimmune reactions. The primary causes of these diseases remain unknown. However, thanks to the recent studies in immunogenetics, progress has been made in understanding the mechanisms underlying these pathologies. Moreover, studies are being held on identification of specific autoantigens in these diseases. The results of these studies are criteria of diagnosis and treatment of those diseases. As there is still no specific treatment of PBC and PSC, in many cases best results are achieved with allogenic orthotropic liver transplantation.
