Initially living donor liver transplantation (LDLT) was almost exclusively performed in infants and children. Adult LDLT programmes were initiated several years later. In the west this programme was introduced in view of a critical shortage of deceased donors and a constant increase in waiting list mortality. At present, this procedure is accepted as a therapeutic option for patients with end-stage liver disease to make up for the shortage of donor organs from dead patients. In Asia, however, LDLT has become the predominant means of liver transplantation as donor organs from the diseased cannot be used for religious and ethical reasons. Although there have been significant improvements in surgical techniques and consequently in recipient outcome over recent years, the LDLT procedure is still associated with donor morbidity and even mortality. The overall reported donor mortality was 0.2% and donor morbidity ranged between 0% and 100%. Biliary complications and infections were the most commonly reported donor complications. Therefore, a thorough medical as well as psychological evaluation of the donor and recipient are necessary prior to this procedure. To date, LDLT comprises less than 5% of adult liver transplantations in Europe and in the United States. Recipient and graft survival are almost identical to those seen with liver transplantations from deceased donors (DD). Biliary and vascular complications are more often seen in the LDLT setting. So far, no studies have focussed on the impact of LDLT on waiting list mortality. There is international consensus that this procedure should be restricted to centres with large experience in deceased donor liver transplantations as well as in hepatobiliary surgery. Ethical issues, optimal utility and application of adult LDLT and optimal recipient and donor characteristics have yet to be defined. 相似文献

Papillitis and vasculitis of the arteria spinalis anterior as complications of hepatitis C reinfection after liver transplantation 总被引:1,自引:0,他引:1

It is well known that hepatitis C virus (HCV)-related chronic liver disease may be associated with various immunological
disorders including mixed cryoglobulinemia, which is accompanied by cutaneous vasculitis, arthralgias, membranoproliferative
glomerulonephritis, and neuropathy in association with cryoprecipitable immune complexes in serum. We describe here the first
case of central nervous system HCV infection with evidence of the virus in the cerebrospinal fluid in association with cryoglobulinemia
in a patient who developed recurrent episodes of papillitis and vasculitis of the arteria spinalis anterior after liver transplantation.

The enantiomers of the positive inotropic and a1-adrenoceptor blocking agent saterinone (+/-)-1,2-dihydro-5-[4-[2-hydroxy-3- [4-(2-methoxyphenyl)-1-piperazinyl]propoxy] phenyl]-6-methyl-2-oxo-3-pyridine-carbonitrile, BDF 8634) have been investigated with in vitro and in vivo models in laboratory animals. In the guinea pig papillary muscle, saterinone enantiomers had equipotent inotropic activity and were also as potent as racemic saterinone; the (R)-enantiomer, however, exhibited a greater efficacy than the related compounds. Saterinone and its enantiomers were equipotent in the inhibition of phosphodiesterase PDE III activity in the guinea pig myocardium. The equipotent inotropic effects were also observed after parenteral and enteral administration in cats. In receptor binding studies, (S)-saterinone was 10-fold more potent than (R)-saterinone by inhibiting [3H]-prazosin binding to specific alpha 1-adrenoceptor sites in rat brain cortex membranes. However, in the isolated thoracic aorta of the rabbit, (S)-saterinone was only 3-fold more potent than (R)-saterinone at preventing the pressor effects of phenylephrine. When the enantiomers were tested in vivo against the pressor effects of phenylephrine in the pithed rat, (S)-saterinone was only 2-fold more potent than (R)-saterinone in its alpha 1-adrenoceptor blocking potency. Thus the enantiomers of saterinone do not display enantio-selectivity in their inotropic and PDE III inhibitory effects in vitro, nor in their cardiotonic effects in vivo. There is a slight enantio-selectivity at alpha 1-adrenoceptors in receptor binding studies, but this is reduced to biologically irrelevant magnitude in functional studies in vitro and in vivo. 相似文献

Heart failure due to myocardial iron overload remains the leading cause of morbidity and mortality in adult thalassemia major (TM) patients. We evaluated the removal of cardiac iron and the changes of cardiac function by different iron chelation in TM patients by T2* cardiac magnetic resonance (CMR). Sixty-seven TM patients (27 males/40 females; mean age, 35 ± 6 years) on different chelation regimens underwent T2* CMR at baseline (t (0)), after 6-14 months (t (1)) and after 32 ± 7 months (t (2)). Patients were divided in four groups according to chelation treatment: group A (deferasirox), group B (deferoxamine), group C (combined treatment, deferoxamine plus deferiprone) and group D (deferiprone alone). Myocardial T2* at t (0) was <10 ms in 8 patients, between 10 and 20 ms in 22 patients and ≥ 20 ms in 37 patients. Progressive changes in T2* were observed at t (1) and t (2). Ten patients (10/36, 27.8 %) in group A, three patients (3/15, 20 %) in group B and three patients (3/12, 25 %) in group C moved from an abnormal T2* to normal values. We observed an improvement of left ventricular ejection fraction and a reduction of end-systolic and end-diastolic left ventricular volumes only in patients in group A with baseline cardiac T2* between 10 and 20 ms. Rigorous compliance to any chelation therapy at proper doses significantly improve myocardial T2*. Treatment with deferasirox significantly improves left ventricular function. Combination therapy seems to ameliorate cardiac T2* in a shorter period of time in severe siderosis. 相似文献

Hepatitis C virus (HCV) infection causes not only acute and chronic liver disease, but also extrahepatic symptoms. To our knowledge, this is the first case report of a patient who developed simultaneously subacute cutaneous lupus erythematosus and a small CD20+ B-cell clone because of chronic HCV infection and relapse after standard of care therapy (pegylated interferon plus ribavirin). Treatment with rituximab, a chimeric anti-CD20 monoclonal antibody, was successful. 相似文献

Patients suffering from primary sclerosing cholangitis (PSC) show considerable differences regarding clinical manifestations (i.e. large duct versus small-duct PSC, presence or absence of concomitant inflammatory bowel disease), disease progression, risk for malignancy and response to therapy, raising the question whether PSC may represent a mixed bag of diseases of different aetiologies. The growing list of secondary causes and diseases 'mimicking' or even overlapping with PSC (e.g. IgG4-associated sclerosing cholangitis), which frequently causes problems in clear-cut discrimination from classic PSC and the emerging knowledge about potential disease modifier genes (e.g. variants of CFTR, TGR5 and MDR3) support such a conceptual view. In addition, PSC in children differs significantly from PSC in adults in several aspects resulting in distinct therapeutic concepts. From a clinical perspective, appropriate categorization and careful differential diagnosis are essential for the management of concerned patients. Therefore, the aim of the current review is to summarize current and evolving pathophysiological concepts and to provide up-to-date perspectives including future treatment strategies for PSC. 相似文献

The Organ shortage has caused an accumulation of acutely decompensated patients listed as medical urgency code 2 (MUC 2) (United network for Organ Sharing 2) while awaiting liver transplantation. Between June 1997 and June 2003, 22 of 360 liver transplantation patients (6%) were listed as MUC 2. Prophylactic immunosuppression consisted of calcineurin inhibitor-based drug therapy, using antithymocyte globulin or interleukin-2 receptor antagonist induction in 64%. The overall perioperative infection rate was 50%, and the rejection rate was 23%. We observed 7 episodes of oral or genital herpes simplex virus lesions; 2 patients (both with cytomegalovirus-mismatched transplants) developed cytomegalovirus disease, and another 5 patients received ganciclovir for preemptive therapy or prophylaxis. Two patients developed pneumonia: 5, sepsis that originated in 4 cases from a contaminated central venous line; and 1 methicillin-resistant endocarditis, which resulted in Staphylococcus aureus lethal outcome. After a median follow up of 3 years, 1 patient underwent a repeat transplantation procedure and 6 patients had died, 4 of them from infectious complications. Liver transplantation of MUC 2-listed patients may result in acceptable results similar to those of MUC 3 and MUC 4 categories. 相似文献
