Uber die Seropravalenz von Hepatitis C bei Fluchtlingen, die im Jahr 2015 nach Deutschland gekommen sind, gibt es bisher keine validen Informationen. Dokumentation der Seropravalenz von Anti-HCV bei Fluchtlingen und Asylbewerbern in Norddeutschland im Jahr 2015. Im August 2015 wurden im Rahmen einer medizinischen Erstversorgung bei 236 Fluchtlingen zwischen 3 und 74 Jahren HCV-Antikorper bestimmt. 76,7 % der Fluchtlinge waren mannlich, das mittlere Alter lag bei 28,7 ± 11,8 Jahren. 10,0 % waren Kinder und Jugendliche unter 18 Jahren. Bei nur einem mannlichen Fluchtling (1/236; 0,42 %) war die Testung auf Anti-HCV reaktiv. Die Analyse der Migrantenseren zeigt insgesamt eine niedrige Pravalenz der Hepatitis-C-Virusinfektion bei Fluchtlingen und Asylbewerbern. Die Pravalenz bei Migranten unterscheidet sich nicht von der Pravalenz in der deutschen Normalbevolkerung. Ein systematisches Screening aller Asylbewerber auf Hepatitis C scheint somit nicht gerechtfertigt. Bekannte Risikofaktoren und klinische Manifestationen sollten aber, genauso wie in der deutschen Allgemeinbevolkerung, zu einer Testung fuhren.

Introduction Nodular hyperplasia of parathyroid glands (PG) is the most probable cause of medical treatment failure in secondary hyperparathyroidism (sHPT). This prospective cohort study is located at the interface of medical and surgical consideration of sHPT treatment options and identifies risk-factors for nodular hyperplasia of PG. Material and methods One-hundred-eight resected PG of 27 patients with a broad spectrum of sHPT severity were classified according to the degree of hyperplasia by histopathology. Twenty routinely gathered parameters from medical history, ultrasound findings of PG and laboratory results were analyzed for their influence on nodular hyperplasia of PG by risk-adjusted multivariable binary regression. A prognostic model for non-invasive assessment of PG was developed and used to weight the individual impact of identified risk-factors on the probability of nodular hyperplasia of single PG. Results Independent risk-factors for nodular hyperplasia of single PG were duration of dialysis in years, PG volume in mm3 determined by ultrasound and serum level of parathyroid hormone in pg/mL. Multivariable analyses computed a model with an Area Under the Receiver Operative Curve of 0.857 (95%-CI:0.773–0.941) when predicting nodular hyperplasia of PG. Theoretical assessment of risk-factor interaction revealed that the duration of dialysis had the strongest influence on the probability of nodular hyperplasia of single PG. Conclusions The three identified risk-factors (duration of dialysis, PG volume determined by ultrasound and serum level of parathyroid hormone) can be easily gathered in daily routine and could be used to non-invasively assess the probability of nodular hyperplasia of PG. This assessment would benefit from periodically collected data sets of PG changes during the course of sHPT, so that the choice of medical or surgical sHPT treatment could be adjusted more to the naturally changing type of histological PG lesion on an individually adopted basis in the future.

We are presenting the case of a 42-year-old male patient, who was hospitalized due to an acute small bowel obstruction caused by a tissue mass of the mesentery. The patient reported that he had a history of a testicular tumour. For therapy of intestinal obstruction as well as for diagnostic reasons we decided to perform an explorative laparotomy. On histopathological examination the immunohistological staining was positive for myeloperoxidase (MPO) and KP-1 (CD68). Staining was slightly positive for Bcl-2, CD117, CD34, but negative for CD3, CD4, CD5, CD8, CD20, CD30, CD79, Bcl-6 and S-100. This leads to the diagnosis of a myeloid sarcoma. After recovery from surgery and chemotherapy, allogenic bone marrow transplantation was performed. Most intestinal obstructions are caused by postoperative adhesions or hernias and only in rare cases caused by a myeloid sarcoma.

Split liver transplantation (SLT) is clearly beneficial for pediatric recipients. However, the increased risk of biliary complications in adult recipients of SLT in comparison with whole liver transplantation (WLT) remains controversial. The objective of this study was to investigate the incidence and clinical outcome of biliary complications in an SLT group using split extended right grafts (ERGs) after ex situ splitting in comparison with WLT in adults. The retrospectively collected data for 80 consecutive liver transplants using ERGs after ex situ splitting between 1998 and 2007 were compared with the data for 80 liver transplants using whole liver grafts in a matched-pair analysis paired by the donor age, recipient age, indications, Model for End-Stage Liver Disease score, and high-urgency status. The cold ischemic time was significantly longer in the SLT group (P = 0.006). As expected, bile leakage from the transected surface occurred only in the SLT group (15%) without any mortality or graft loss. The incidence of all other early or late biliary complications (eg, anastomotic leakage and stenosis) was not different between SLT and WLT. The 1- and 5-year patient and graft survival rates showed no statistical difference between SLT and WLT [83.2% and 82.0% versus 88.5% and 79.8% (P = 0.92) and 70.8% and 67.5% versus 83.6% and 70.0% (P = 0.16), respectively]. In conclusion, ERGs can be used safely without any increased mortality and with acceptable morbidity, and they should also be considered for retransplantation. The significantly longer cold ischemic time in the SLT group indicates the potential for improved results and should thus be considered in the design of allocation policies.

History and clinical findings A 41-year-old woman, known for 10 month to have polycythaemia vera, developed severe right upper abdominal pain. The abdomen was tense from marked ascites and the liver enlarged by 18 cm in the mid-clavicular line. Investigations Serum bilirubin was slightly elevated to 2.2mg/dl, liver synthesis being much reduced (recalcifying time minimally 23%, albumin minimally 2.8 g/dl). Doppler sonography detected no flow in the right and middle hepatic veins, indicating Budd-Chiari syndrome. Portal vein flow was diminished. Treatment and course Heparin treatment had to be stopped because of heparin-associated type II thrombocytopenia and hirudin was substituted. Attempted lysis with a total of 100 mg r-tPA failed. As the patient's condition deteriorated a TIPSS was implanted to provide portal decompression. Incomplete portal vein thrombosis was demonstrated and worsened during the procedure until nearly complete occlusion. Local lysis treatment for 2 days with urokinase, 50,000-60,000 U/h, and two shunt revisions finally succeeded in completely dissolving the thrombus. Portocaval pressure fell from 32 to 21 mm Hg, and the size and function of the liver became almost normal and the ascites disappeared. Anticoagulation with a coumarin derivative was started and hydrocarbamide again given for recurrent thrombocytosis. The patient remained largely symptom-free one year after TIPSS. Conclusion This case demonstrates the effectiveness of TIPSS in Budd-Chiari syndrome, even in complicated portal vein thrombosis.

In a 38-year-old man combined heart and kidney transplantation was performed successfully in one operation. Both organs have functioned well postoperatively: the patient was discharged from hospital on the 19th postoperative day and has remained in functional class I (New York Heart Association) eight months later. Only two episodes of cardiac rejection have been observed during this period, responding to treatment, and there was no evidence of rejection of the kidney. Such combined heart-kidney transplantation from one donor seems to be a promising form of treatment for patients in end-stage myocardial and renal failure. The frequency of cardiac rejections my be lower after combined heart-kidney transplantation than after cardiac transplantation alone.

HISTORY AND CLINICAL FINDINGS: A 55-year-old woman with known primary biliary cirrhosis (PBC) was hospitalized because of increasing dyspnoea. A year before she had for the first time experienced a right-sided pleural effusion which had to be drained every 4 weeks. Physical examination revealed dullness on percussion and greatly decreased breath sounds on auscultation over the entire right thorax. In addition there were signs of moderate ascites and leg oedema. INVESTIGATIONS: Chest radiograph showed a homogeneous shadowing of the right thorax without mediastinal shift. Diagnostic thoracocentesis produced a serous effusion, a transudate on chemical analysis, comparable to the composition of the ascitic fluid. Bacteriological and cytological tests on both fluids were unremarkable. TREATMENT AND COURSE: The right pleural effusion was presumed to be due to a hydrothorax from the ascites caused by portal hypertension associated with the PBC. Despite continuous diuretic treatment and thoracocentesis with albumin substitution every 3 days there was no improvement and implantation of a transjugular intrahepatic portosystemic stent shunt (TIPSS) was performed. This effectively lowered portal pressure and markedly improved the patient's condition so that further thoracocentesis were no longer necessary. 3 weeks after TIPSS implantation she was discharged in good condition. Radiography 3 weeks later demonstrated continued reduction in the hydrothorax. CONCLUSION: Hydrothorax is a rare complication of liver cirrhosis. TIPSS implantation can provide lasting resolution and corresponding clinical improvement of a hydrothorax, especially in those conditions which are refractory to diuretic treatment and thoracocentesis.

Die Abernethy-Malformation, der angeborene portosystemische Shunt, ist eine seltene Fehlbildung (bislang sind knapp 100 Falle publiziert), bei der das Blut aus dem mesenterialen Kreislauf unter Umgehung der Leber entweder vollstandig (Typ 1, totaler portosystemischer Shunt) oder teilweise (Typ 2, partieller portosystemischer Shunt) direkt der V. cava inferior zugefuhrt wird. Die Diagnose erfolgt zumeist primar sonographisch. Mit Hilfe der Computertomographie (CT) und Magnetresonanztomographie (MRT) kann die Gefasfehlbildung genauer klassifiziert, assoziierte Lebertumoren und begleitende Fehlbildungen zusatzlich detektiert bzw. ausgeschlossen werden. Die Therapieoptionen reichen von konservativen Masnahmen bis hin zur Lebertransplantation. Die Prognose ist nicht zuletzt von den haufig begleitenden Lebertumoren und den evtl. assoziierten weiteren Fehlbildungen abhangig. Wir berichten uber 2 junge Patienten mit einem Typ-1-Shunt, hepatischer Enzephalopathie und assoziierten Lebertumoren, bei denen unter Abwagung aller Aspekte schlieslich die Lebertransplantation erfolgreich durchgefuhrt wurde.

Undifferentiated small-cell hepatoblastoma (HB) is a rare malignant tumor of childhood. The cell of origin is supposed to be a pluripotential, probably entodermal, stem-cell. Differential diagnosis of this type of HB is difficult among the group of small round and blue cell malignant tumors of children. The immunohistochemically determined coexpression of cytokeratin 8, 18, and 19 and of vimentin and actin, regularly in the absence of alpha-fetoprotein expression may be diagnostically helpful. We present the case of an undifferentiated small-cell HB of a 15-month-old girl with agenesis of the right kidney. As morphological peculiarity the tumor presented disseminated histiocytic giant cells.

Orthotopic liver transplantation had been performed in 1983 in a now 40-year-old woman in the terminal stage of posthepatitis liver cirrhosis with recurrent oesophageal bleedings and precoma from complete liver-cell failure. She became pregnant in 1988 while under immunosuppression with cyclosporin (2.1-2.7 mg/kg body-weight) and prednisolone (5 or 7.5 mg daily in rotation). Pregnancy proceeded without complication and there were no side effects from cyclosporin. After premature membrane rupture in the 39th week of pregnancy uterine inertia developed during oxytocin stimulation of contractions, and caesarean section was performed. The female infant was normally developed without any malformations. Liver, kidney and adrenal functions were normal, as was haemopoiesis. But possible late sequelae of cyclosporin treatment in the child cannot as yet be assessed because of the short follow-up.

Treatment of ureteral stenosis has been attempted in many patients with transplanted kidneys. Treatment with the Acucise catheter system is a new approach for such patients. Published results of the approach in eight patients promise safety, effectiveness, and low perioperative morbidity. We report two cases of transplant ureteral stenosis treated with Acucise. One patient with stenosis of the pyeloureteral junction was treated successfully and has been free of recurrence for 9 months. The other patient had long-distance stenosis of the lower portion of the transplant ureter. Acucise incision was successful, but the patient had to undergo uretero-neocystostomy because of a ureteroperitoneal fistula. We use these cases to illustrate the disadvantages of endourological ureteral surgery as a standard therapeutic approach after renal transplantation. We suggest that Acucise is reliable when used in patients with uncomplicated short-distance ureteral stenosis; however, patients with long-distance stenosis or stenosis caused by heavily scarred periureteral tissue will not profit from it because of a higher complication rate.

Many transplant centers reject donor livers with severe steatosis (> 60%) due to the increased risk of primary graft dys- or nonfunction. However, the discrepancy between available donor organs and the rising number of transplant candidates is still unacceptable, because of the death of patients who are on the waiting list. Therefore, marginal donor livers are accepted increasingly to fight this dilemma. Our experience after transplantation of steatotic donor livers shows a recovery tendency with decreasing steatosis after primary graft dysfunction.

Durch Sonographie, Farb-Doppler-Technik, Computer- und Magnetresonanztomographie sowie szintigraphische Methoden gelingt in aller Regel eine gute Differenzierung der haufigsten benignen Lebertumoren. Erganzt wird diese naturlich durch klinische und humorale Untersuchung unter Einschlus von Tumormarkern, um die Verdachtsdiagnose maligne oder benigne zu untermauern. Die Biopsie sollte weitgehend vermieden werden, da die meistens sichere Diagnostik eindeutig nichtmaligner Strukturen durch die genannten Verfahren moglich ist und malignitatsverdachtige Strukturen ohnehin eine Operation notwendig machen, sofern der Zustand des Patienten dies erlaubt. In dieser Arbeit werden nur die benignen soliden Lebertumoren behandelt, nicht die (poly-)zystischen, parasitar zystischen Lebererkrankungen und Abszesse.

Anlaslich der Abklarung von Herzrhythmusstorungen wurde bei einem 59-jahrigen Patienten deutscher Herkunft eine Familiare Amyloid Polyneuropathie (FAP) mit hypertropher Kardiomyopathie, beginnender peripherer Polyneuropathie, AV-Block I. Grades, intermittierend II. Grades Typ MOBITZ, und einer Aminosauresubstitution von Glycin durch Alanin an Position 47 des Transthyretins (TTR Ala47) diagnostiziert. Um die weitere Bildung und Ablagerung des mutierten Transthyretins zu reduzieren und den Progres der Erkrankung zumindest aufzuhalten, wurde die Indikation zur Lebertransplantation gestellt. Bei sonstiger Symptomfreiheit entwickelte der Patient bereits vor Transplantation eine progrediente Inappetenz. Postoperativ erhielt der Patient eine enteral-supportive Ernahrung uber Duodenalsonde fur einen Zeitraum von 30 Monaten, bis sich der Appetit verbesserte und das Korpergewicht stabilisierte. In Biopsien der Duodenalschleimhaut lies sich 24 Monate nach Transplantation weiterhin Amyloid nachweisen. Wie bereits vorTransplantation bestanden eine Verminderung von Magenperistaltik und Duodenalmotilitat sowie eine hypertrophe Kardiomyopathie ohne wesentliche funktionelle Einschrankungen. Eine diskrete Verbesserung der sensomotorischen Polyneuropathie konnte anhand der Normalisierung elektromyographischer Veranderungen belegt werden. 12 Monate nach Transplantation waren nur noch Spuren der Transthyretinvariante (TTR Ala47) im Plasma zu finden. Wahrend des bisherigen Beobachtungszeitraumes von mehr als 3 Jahren nach Transplantation sind keine neuen Symptome aufgetreten. Eine Progression der Erkrankung konnte eindeutig verhindert werden. Die orthotope Lebertransplantation ist gegenwartig die einzige erfolgversprechende Therapieform, um eine Progression der Familiaren Amyloid Polyneuropathie zu verhindern.

Background/Aims: The development of liver fibrosis due to chronic liver diseases is thought to be mediated by inflammatory cells releasing fibrogenic mediators that activate fat-storing cells (Ito-cells). Recently, the involvement of mast cells in fibrogenesis has been suggested. We studied the distribution of these cells in normal human liver and human nonfibrotic and fibrotic liver disease as well as in normal rat liver and acutely and chronically injured rat liver (CCl 4 model). Methods: Mast cells were identified by histochemical and immunohistochemical methods. The immunoreactivity of liver and comparatively of rat peritoneal mast cells to the serpins alpha1-antitrypsin, alpha1-antichymotrypsin and antithrombin III was also studied. Results: In normal human and rat liver, mast cells were rarely found in portal tracts, and there was no change in cell numbers in nonfibrotic human or acutely injured rat livers. In contrast, cirrhotic human and rat livers contained numerous mast cells in the portal tracts and the fibrous septa. They exhibited strong immunoreactivity to the serpins, as did rat peritoneal mast cells. Conclusions: The results indicate that in the late stages of liver fibrogeneis, mast cells may be involved by diplaying protease inhibitory activity in the fibrotic septa.

OBJECTIVE: This article describes the experience with liver transplantation in patients with irresectable neuroendocrine hepatic metastases. SUMMARY BACKGROUND DATA: Liver transplantation has become an established therapy in primary liver cancer. On contrast, there is little experience with liver transplantation in secondary hepatic tumors. So far, in the majority of patients being transplanted for irresectable liver metastases, long-term results have been disappointing because of early tumor recurrence. Because of their biologically less aggressive nature, the metastases of neuroendocrine tumors could represent a justified indication for liver grafting. METHODS: In a retrospective study, the data of 12 patients who underwent liver transplantation for irresectable neuroendocrine hepatic metastases were analyzed regarding survival, tumor recurrence, and symptomatic relief. RESULTS: Nine of 12 patients currently are alive with a median survival of 55 months (range, 11.0 days to 103.5 months). The operative mortality was 1 of 12, 2 patients died because of septic complications or tumor recurrences or both 6.5 months and 68.0 months after transplantation. all patients had good symptomatic relief after hepatectomy and transplantation. Four of the nine patients who are alive have no evidence of tumor with a follow-up of 2.0, 57.0, 58.0, and 103.5 months after transplantation. CONCLUSIONS: In selected patients, liver transplantation for irresectable neuroendocrine hepatic metastases may provide not only long-term palliation but even cure. Regarding the shortage of donor organs, liver grafting for neuroendocrine metastases should be considered solely in patients without evidence of extrahepatic tumor manifestation and in whom all other treatment methods are no longer effective.

To identify pretransplant factors that are influencing survival after orthotopic liver transplantation a Cox proportional hazards regression model was applied to 118 children with chronic terminal liver failure transplanted at Medical School Hannover during the period of 1978 to 1994. The response variable was survival, as covariates a total of 19 pretransplant variables were entered--i.e. age, diagnosis (biliary cirrhosis, metabolic cirrhosis, postnecrotic cirrhosis, cryptogenetic cirrhosis) sex, laparotomy prior to OLT, height, weight, standard deviation scores for height and weight, date of first OLT, serum alanine aminotransferase, asparagine aminotransferase, albumin, total bilirubin, cholinesterase activity, glomerular filtration rate, and prothrombin time. Significant independent predictors of survival after OLT were bilirubin (P=0.0024), SDS for weight (P=0.034), and albumin (P=0.039). In a subsequent discriminant analysis cut off points for these variables could be identified--i.e., bilirubin >340 micromol/L, SDS for weight

Post-transplant assessment of early graft function has become an essential part of monitoring, especially when deciding on retransplantation. If primary non-function is indicated, retransplantation is inevitable; early graft dysfunction may be related to subsequent complications. In a prospective study in 84 patients after orthotopic liver transplantation (OLT) we measured aspartate aminotransferase (AST), alanine aminotransferase (ALT), glutamate dehydrogenase (GLDH), bilirubin (BIL), prothrombin time, MEGX formation, hyaluronic acid (HA) and soluble interleukin-2 receptor (sIL-2R) concentrations during the first 2 postoperative weeks; graft outcome was followed over 4 months. The aim of this study was to determine whether graft survival could be predicted by such variables early after OLT. Compared with patients with stable graft function (n = 25), patients with post-transplant icteric cholestasis (n = 30) exhibited no difference in graft survival, despite a decrease in MEGX formation to a nadir median of 12 micrograms L-1 on day 10. Patients with rejection (n = 8) and septicaemia (n = 6) showed a marked decrease in MEGX values and an increase in HA and sIL-2R concentrations between postoperative days 3 and 7. Patients with primary non-function (PNF; n = 5) were characterized by strongly reduced MEGX formation (median 4 micrograms L) and increased HA values (median 2300 micrograms L-1) on day 3 after OLT. A total of 24/84 grafts were lost within 120 days. In a survival analysis using the Cox proportional hazards regression, HA and MEGX values on day 1 were the only independent variables entering the model that showed an adequate prognostic sensitivity. At cut-off points of 22 micrograms L-1 (MEGX) and 730 micrograms L-1 (HA) the combined use of these parameters in a parallel approach yielded a sensitivity of 58% with a corresponding specificity of 95% for 120-day graft survival. These findings suggest that the inclusion of MEGX and HA in postoperative monitoring of OLT patients may be helpful in the early prediction of graft survival.

The immunosuppressive effect of a monoclonal antibody (moAb), BT563, directed to the alpha-chain of the IL-2R (CD25), was analyzed in a prospective nonrandomized trial and a prospective randomized trial. Primary objectives were evaluation of the incidence of acute rejections and infections; secondary objectives were safety and tolerability of the moAb. A total of 28 patients were enrolled (phase II) to receive 10 mg/day of BT563 (12 days) as immunoprophylaxis in combination with cyclosporine, azathioprine, and low-dose steroids. Subsequently 32 patients were randomly assigned (phase III) to receive BT563 (10 mg/day) for 12 days or ATG (5 mg/kg/day) for 7 days in addition to cyclosporine and low-dose steroids. No side effects of the BT563 treatment were noted. The actuarial survival was 82% at 12 months in the phase II trial and 92% at 12 months in both arms of the phase III trial. There was one acute rejection in the phase II trial. No acute rejections were noted in the BT arm of the phase III trial and 5 acute rejections were treated in the ATG arm. In the phase II trial 7 infectious episodes were observed, while one infection was seen in the BT arm and 7 in the ATG arm of the triple immunosuppression phase III trial. In all patients circulation of coated CD25+ lymphocytes was observed during BT563 treatment; there was no evidence of depletion or modulation of CD25+ cells. Mean serum levels of BT563 ranged from 1.6 to 7.6 microgram/ml throughout the therapy. An antimurine response was seen in 82% (phase II) and 100% (phase III) of the patients. Antirabbit antibodies were found in 56% of the patients treated with ATG. Analysis of the antimurine response specificity revealed in 56% blocking anti-isotypic antibodies and only in 3% of the patients an anti-idiotypic response. The data of the study presented suggest that therapy with an anti IL-2R moAb is at least equal to ATG application according to the incidence of acute rejections and infections.

Regulatory roles of insulin and glucagon in hepatic metabolism and function are well described. However, little is known about implications of host pancreatic hormones in primary function of grafted liver. This study aimed to investigate it in relation to hepatic mitochondrial function. Insulin, c-peptide, and glucagon in peripheral blood were monitored for 2 days in clinical liver transplantation by a continuous sampling technique to avoid influences of hormonal oscillation. In grafts with immediate function (n = 10), smooth increase of arterial ketone body ratio reflecting hepatic intramitochondrial redox state was accompanied by increased c-peptide and decreased glucagon, resulting in the increase of c-peptide/glucagon ratio. In other functioning grafts (n = 20), where ketone body ratio was rather lower, increased glucagon level, observed also during anhepatic phase, resulted in the slower increase of c-peptide/glucagon ratio. There were accompanied by increased free fatty acid and ketone body levels. In primary nonfunction (n = 4), rapid increase of c-peptide accompanied by hyperglycemia resulted in the accelerated increase of c-peptide/glucagon ratio, but ketone body ratio did not show any increase. Insulin/c-peptide ratio also showed a rapid increase. These findings suggest that the increase of insulin/glucagon ratio in portal blood, potentially influenced by recipient condition, is associated with the recovery of mitochondrial energy metabolism in survived hepatic grafts. However, this relationship does not work in failed grafts, where irreversible impairment of energy metabolism is attributed to graft itself.

Intrahepatic cholangiocellular carcinoma (CCC) is known to be associated with severe symptoms and a particularly poor prognosis. Nonsurgical methods have failed to change this situation up to now. Surgical therapy, so far, is the only chance for effective treatment, but it has had limited success. The relative infrequency of this tumor does not allow extensive statistics and limits our present knowledge. In this contribution the outcome of 50 patients who underwent liver resection or liver transplantation in our institution is reported. Their courses have been reevaluated according to pathohistologic classification and TNM tumor staging. The median survival rates were 12.8 months in the group of patients after liver resection (n = 32) and 5.0 months after liver transplantation (n = 18). Liver transplantation, however, was performed only in patients with unresectable tumors. The longest survival after transplantation was 25 months; after resection four patients survived more than 5 years. In the resection group and the transplantation group survival rates correlated with tumor size and tumor stages according to TNM, although the differences were not statistically significant. Liver resection thus has its place in resectable situations. Liver transplantation for unresectable lesions of this tumor type--always deemed critically in the past--seems not to be indicated with our present stage of knowledge, unless adjuvant protocols appear promising and are tested.

By retrospective analysis of 13,000 blood samples obtained from 248 patients receiving FK 506 therapy, we compared the suitability of plasma with that of whole blood as the matrix for therapeutic drug monitoring of FK 506. The plasma concentrations did not correlate with the concentrations in whole blood (r = 0.56). In contrast to plasma samples (analyzed by enzyme immunoassay), FK 506 was detectable in all whole-blood samples (analyzed by enzyme immunoassay/microparticle enzyme immunoassay). The inter- and intraindividual variations of FK 506 measurements were greater in plasma than in whole blood. Moreover, plasma concentrations correlated only poorly with clinical events. There was a tendency to greater plasma concentrations being measured during episodes of toxicity, but no clear difference was evident between stable course and rejection. In whole-blood specimens, a correlation between reduced or increased FK 506 concentrations and rejection or toxicity, respectively, was observed. The discriminatory power of whole-blood values was greater for the differentiation between toxicity and stable course than between rejection and stable course. We therefore recommend whole blood rather than plasma as the matrix for therapeutic monitoring of FK 506 concentrations.

To study the neurological sequelae in liver transplanted recipients, 25 patients were followed up between 5 and 30 months after transplantation and another 14 patients were seen before and after transplantation. Physical examination took special note of tremor and polyneuropathy; additionally, patients estimated concentration and memory, tremor, paraesthesias and sleep disturbances on a self-rating scale. Tremor was reported to be preexistent in 50% of the later FK 506 and cyclosporin group and only temporarily rose afterwards. Twenty-eight percent complained of tremor and 20 % said that it interfered mildly with daily activity. Only 2 of 39 patients showed new signs of polyneuropathy. Concentration and memory improved significantly after transplantation. In the second group of patients, MRI, EEG, lumbar puncture and neuropsychological tests were done just before and routinely after transplantation, revealing numerous preexisting neurological deficits with only singular changes afterwards.

A pilot study was performed in patients after liver transplantation (Ltx) to examine the effect of continuous intravenous urodilatin (URO, CDD/ANP-95-126)-infusion as an alternative therapy of acute renal failure (ARF) resistant to conventional therapy. Eight patients who developed ARF after liver transplantation and fulfilled requirements for haemodialysis/haemofiltration were treated. After URO infusion was started, renal function improved and all patients developed a strong diuresis and natriuresis within 2-4 h. The extracellular expansion due to sodium and water retention in anuric/oliguric ARF lead to an increased central venous pressure (CVP) and elevated blood pressure. During the URO infusion CVP declined and systolic, as well as diastolic, blood pressure were stable. In six patients where haemodialysis/haemofiltration could be avoided, serum creatinine (SC) and blood urea nitrogen (BUN) declined during URO treatment and creatinine clearance (CC) also improved significantly. Fluid and electrolyte disturbances changed promptly and normalized. This was in concordance with renal excretion of electrolytes. Two patients still required haemodialysis/haemofiltration. The six patients who did not require haemodialysis/haemofiltration after URO treatment normalized concerning their renal function and did well in a control period of 12 weeks. The study shows that continuous low dose URO infusion may present a new concept for treatment of postoperative acute renal failure resistant to conventional therapy.

FK 506 plasma levels were analyzed in 89 liver-grafted patients under FK 506-based immunosuppression. Plasma levels were found to be influenced by the patients' liver function: compared to patients without major liver dysfunction, those with cholestasis had higher plasma levels and these plasma levels were able to differentiate between rejection and toxicity. In patients with stable liver function, no clear difference was observed with regard to the plasma levels detectable during toxicity or rejection. We conclude that plasma levels can be used to determine the FK 506 dose but only in patients with cholestasis (i.e., during the early post-transplant course, or in patients with cholestatic rejection). In patients with stable liver function, plasma levels are only of limited clinical relevance.

A 53-year-old man with alpha-1-antitrypsin deficiency had an 8-year history of progressive dyspnoea and two episodes of bleeding oesophageal varices with liver decompensation. After the diagnosis of terminal pulmonary emphysema (Fig. 1) and liver cirrhosis with progressive liver failure was made, he was accepted for combined lung and liver transplantation. METHODS. Anaesthesia was induced with thiopentone and fentanyl and maintained with fentanyl, midazolam, and isoflurane. After relaxation with succinylcholine, the patient's trachea was intubated with a left endobronchial double-lumen tube. Haemodynamic monitoring included arterial, central-venous, pulmonary-artery, and capillary-wedge pressures and cardiac output measurement. Ventilatory monitoring consisted of pulse oximetry, side-stream spirometry, and continuous measurement of arterial and mixed-venous blood oxygen saturation with fibreoptic catheters. A left single-lung transplantation was performed under one-lung ventilation without cardiopulmonary bypass. Prostacyclin was infused to reduce pulmonary vascular resistance. The transplant was ventilated separately with 50% oxygen and positive end-expiratory pressure of 8-10 cm H2O, and then liver transplantation was carried out. The institution of veno-venous bypass during the anhepatic phase failed because of portal-vein and axillary-vein thrombi. RESULTS. Total operation time was 6 h 30 min. Clamping of the left pulmonary artery lasted 45 min and the duration of the anhepatic phase was 92 min. Ventilation and oxygenation during lung transplantation caused no problems (Table 1). Clamping of the left pulmonary artery caused a slight increase in pulmonary vascular resistance (104 to 124 dyn.s.cm-5) and mean pulmonary artery pressure (25 to 27 mm Hg) without a decrease in cardiac index (Table 2). During the anhepatic phase with exclusion of the portal vein and inferior vena cava, a marked decrease in cardiac index (-27.2%) was seen (Table 4). The operation required substitution with 10 units packed red blood cells, 12 units fresh frozen plasma, and 5 platelet concentrates. The post-operative course showed normal liver graft function (Table 5). Acute pulmonary rejection on the 7th day was treated successfully with methylprednisolone. The patient's trachea has extubated 10 days after transplantation and he was discharged from the intensive care unit 2 weeks later. CONCLUSION. The management of this combined lung and liver transplantation was performed according to the experience with isolated lung and liver transplants in our hospital. Aggressive haemodynamic and ventilatory monitoring, including systemic and pulmonary arterial fibreoptic catheters, seems of particular importance in such high-risk procedures.

To evaluate the ability of arterial ketone body ratio (AKBR; acetoacetate/3-hydroxybutyrate) to predict graft prognosis after liver transplantation, the diagnostic value as a predictive index was compared between AKBR and conventional liver function tests using receiver operating characteristic (ROC) analysis. The ROC curves were determined for AKBR, GOT, GPT, total bilirubin, serum lactate level, and prothrombin time, all of which were measured on the 1st and 2nd postoperative days in 88 cases of liver transplantation. Comparisons of the areas under the ROC curves between AKBR and other tests revealed the significant superiority of AKBR to other tests in predicting graft death within 1 month after transplantation. The present study suggests that AKBR can be used as an accurate index to predict graft prognosis after liver transplantation.

In the early postoperative period after liver transplantation a possible neurotropic side effect of middle-chain triglycerides used for total parenteral nutrition (TPN) was evaluated by EEG and Glasgow Coma Scale. Group I: no fat for TPN; Group II: 0.7 g/kg body weight (BW) and day, of MCT/LCT emulsion; Group III: 1.5 g/kg BW and day, of MCT/LCT emulsion. Only on postoperative day 5/6 significant differences in distribution of background activity in the EEG were seen between Group I and II. Patients in Group I showed more pathological EEG patterns (Mann-Whitney-U-test p less than 0.05). Per discriminant analysis an influence of applicated fatty acids on the registered background activity could be excluded. Instead an underlying rejection of the graft in 7 of 10 patients could be made responsible for deterioration of the EEG pattern. Following the presented data a negative neurotropic effect of MCT/LCT emulsions in the described dosages can be negated.

Episodes of graft dysfunction are frequently observed after liver transplantation and can be due to different causes requiring specific therapy. In this study the usefulness and reliability of liver transplant aspiration cytology (TAC) for differential diagnosis of liver graft dysfunction is assessed. Out of more than 1500 TACs performed, 292 TACs, taken during episodes of liver dysfunction due to retrospectively defined causes, were analyzed. Immune activation and parenchymal damage in the aspirates were determined cytologically. In 63 episodes of acute rejection, marked immune activation was present in aspirate but not in blood, with varying degrees of hepatocyte damage and cholestasis. No or only minimal immune activation was observed in 86 cases of toxic, ischemic, or septic liver damage, but considerable parenchymal damage and cholestasis were observed. In 3 cases of hepatitis slight-to-moderate immune activation with large granular lymphocytes was found in the aspirate, while 17 cases of viral infection presented with slight-to-moderate immune activation in aspirate and blood. After successful treatment the cytologic patterns normalized, except when the cause of liver dysfunction persisted. Moreover, typical patterns of parenchymal changes were found for preservation damage of the liver (n = 108), fatty degeneration (n = 3), obstructive cholestasis (n = 5), and acute arterial ischemia (n = 2). One case of moderate subcapsular hematoma was the only complication observed (less than 0.1%). Thus, liver TAC is an easy, safe, and clinically useful method for differential diagnosis of liver graft dysfunction. In particular, differentiation between acute rejection and nonimmunologic causes of dysfunction is very reliable, but hepatitis and viral infections also present distinctive patterns in liver TAC.

Whereas resection for metachronous liver metastases from colorectal cancer is considered to be a potentially curative approach, little is known about the prognosis after resection of synchronous liver metastases. In the past, these patients usually underwent only palliative therapy. Therefore, we have analyzed the data of 36 patients who underwent curative hepatic resection of synchronous liver metastases from colorectal carcinomas from 1977 to 1987 at the Department of Surgery, Hannover Medical School. In 19 patients, liver resection was combined with colonic resection; in the other 17 patients, hepatic resection was performed after a median interval of 2 months following resection of the primary tumor. No operative mortality was observed in either of the approaches. The median survival time was 28 months for all patients with a median recurrence-free interval of 13.5 months. Overall 5-year survival probability for all patients was 20%. There were no significant differences observed between immediate or delayed liver resection (median survival 18 months versus 31 months). Survival rates were not different after resection of solitary versus multiple liver metastases (26 versus 28 months). Twenty-one of the 36 patients had a recurrence of their liver metastases. In 7 of them, curative liver resection could be performed again. These 7 patients had a significantly improved survival (p less than 0.05) compared to the residual 14 patients. It is concluded that patients with synchronous liver metastases from colorectal cancer may profit from resection of the primary tumor and liver metastases. Timing of liver resection--immediate versus delayed--obviously has no impact on survival rates.

The aim of this study was to analyse the immunosuppressive contribution of cyclosporin metabolites in liver-grafted patients. Therefore the immunosuppressive potency of 17 metabolites, alone and in combination, was tested in human mixed lymphocyte cultures, and the results were correlated with metabolite blood levels in liver-grafted patients. Of the 17 metabolites tested only six highly lipophilic metabolites showed a detectable immunosuppressive activity of up to 10% of the activity of cyclosporin; the effect of combining metabolites was additive. For calculation of the in vivo activity, blood levels of seven major cyclosporin metabolites were determined in liver-grafted patients with normal liver function (group A, 43 episodes) and with severe hyperbilirubinaemia (group B, 66 episodes). Both patient groups had comparable levels of parent drug (122.9 +/- 17.4 vs. 111.1 +/- 23.5 ng/ml by HPLC) and similar blood levels of the highly lipophilic metabolites 17, 1 and 18. By contrast, blood levels of the less lipophilic metabolites 8, 9, 26 and 203-218 were substantially increased in group B (P less than 0.05). High overall metabolite blood levels in group B were also indicated by a non-specific monoclonal RIA (520 +/- 199 ng/ml for group A vs. 1318 +/- 407 ng/ml for group B). Despite the very high levels in group B, however, the overall contribution of the metabolites to immunosuppression was similar in both groups (12.6 +/- 5.0% for group A vs. 13.8 +/- 5.6% for group B). These findings indicate that, despite a marked accumulation of cyclosporin metabolites in patients with severe cholestatic liver dysfunction, their immunosuppressive contribution remains low.(ABSTRACT TRUNCATED AT 250 WORDS)

Hepatic energy metabolism was assessed by measuring the blood ketone body ratio (KBR), that is, the ratio of acetoacetate to β-hydroxybutyrate in the arterial blood, in 31 brain-dead patients in an intensive care unit (ICU) in Japan and in 25 donors just before procurement of the liver for transplantation in Germany. In the study in Japan, 7 of the 12 brain-dead patients treated with highdose catecholamine showed significantly decreased KBRs, revealing the detrimental effect of catecholamine on livermmetabolism. In contrast, 8 of the 9 untreated patients with blood pressure below 80 mm Hg showed almost normal KBRs. In the 25 donors in Germany, KBR was maintained within the normal range. Based upon conventional criteria, 21 livers were selected for use and the other 4 were discarded. Nineteen of the grafts were able to normalize KBR within 24 h after reperfusion, while 2 failed to function and required a second transplantation. It was suggested that a KBR in the normal range in donors is a prerequisite to immediate recovery of metabolic function of the liver graft after transplantation, and that hypotensive donors as a potential source of liver grafts may warrant further study.

From 1982 to 1987 sixty-three children were treated with cyclosporin A and low dose prednisolone after kidney transplantation. Patient survival rate at 4 years after transplantation was 98.3 %, survival rate of living related grafts 100 % (n = 10), and survival rate of cadaveric grafts 73 % (n = 53). Adequate cyclosporin blood levels were achieved in all children with a dosage regimen related to body surface area. Major concerns during the observation period were the loss of glomerular filtration rate from 51.8 to 40.5 ml/min/1.73 m2, a hypertension rate of 77.8 %, and hyperuricemia. Cyclosporin A-side effects were mild. Infections occurred in 11.1 %. Growth retardation in prepu-bertal children improved by 0.74 standard deviations of normal height, and in pubertal children by 0.51. We conclude that cyclosporin A treatment in children enables excellent long term graft survival rates with improved growth rehabilitation, however, the prevention of the cyclosporin associated nephrotoxicity and hypertension remains the major problem.

The cardioplegic HTK-solution (Bretschneider) has not been used in human liver transplantation as yet. Herein the first results obtained from 14 patients with HTK-preserved liver grafts are presented. The suitability of HTK-solution could be shown. All grafts functioned primarily except one, where initial non-function was obviously due to donor reasons. The early postoperative peak values of transaminases as a sign of ischemic damage were average and similar to the values of other flushout solutions. Using HTK primary function could be achieved even in livers prospectively assessed as only of fair quality, and livers with poor donor function tests (MegX) functioned from the beginning. HTK-solution therefore seems to allow widening of the acceptance criteria for donor livers. It was not the aim of this trial to extend cold ischemic time, but 3 livers with 11 h and 12 h 25 showed immediate function. How far cold ischemic time can be extended is a still open question. All livers were rapidly cooled and homogeneously flushed out due to the low viscosity of HTK-solution. All livers had a soft consistency after perfusion indicating a low degree of cell edema. HTK therefore is an effective solution for liver preservation.

The Abernethy malformation is a rare congenital portosystemic shunt in which the blood directly drains into the systemic vein bypassing the liver either through a complete (type 1) or a partial shunt (type 2). The diagnosis is most frequently established primarily with ultrasound. CT and MRI are used for further classification of the shunt and assessment of accompanying liver tumors and malformations. There is a wide spectrum of therapeutic options ranging from noninvasive conservative treatment to liver transplantation. The main prognostic factors are the occurrence of concomitant hepatic neoplasms and hepatic encephalopathy. We report two cases diagnosed with a type 1 shunt, hepatic encephalopathy, and associated liver tumors who underwent successful liver transplantation after having considered all therapeutic options.
