Primary effusion lymphoma (PEL) is an unusual form of non-Hodgkin's lymphoma, which is characterized by lymphomatous effusion in body cavities, but no associated mass lesions. It is usually associated with an immunodeficient state most often with the human immunodeficiency virus (HIV). We describe a 54-year-old man with HIV-negative PEL, with a history of hepatitis B virus-related liver cirrhosis. Both abdominal and pleural cavities were involved; no solid tumor masses were found and bone marrow investigations were normal. The ascites and pleural effusion contained numerous pleomorphic lymphoid cells. Immunophenotyping was positive for CD138. Chromosome study showed complex cytogenetics. The genomic human herpesvirus-8 was detected in the lymphoma cells. It is postulated that the immunosuppressed state in this patient may have been caused by cirrhosis. The patient received four cycles of chemotherapy of CHOP and Picibanil (OK-432) intraperitoneal administration. However, no durable remission was achieved. Adefovir failed to halt the progressive liver failure after the development of YMDD mutant related to lamivudine. He died of sepsis and hepatic failure.

This paper reviews a meeting at which basic pathophysiology of infections, mechanisms of action of hyperimmune products and pharmacokinetic and pharmacodynamic parameters, as well as currently available hyperimmunes and their potential new targets and uses, were discussed. A hyperimmune product was defined as either a monoclonal antibody or a polyclonal preparation enriched with antibody directed against one or more particular targets. A number of issues were emphasised, including: resistant bacterial pathogens, such as Staphylococcus aureus and Streptococcus pyogenes; the role of hyperimmune intravenous globulins in the prevention of sepsis in low birthweight infants; hepatitis B virus infection associated with liver transplantation; combination therapy; the potential role of hyperimmunes in the prevention and treatment of hepatitis C virus; and the use of immunoglobulins for the prophylaxis of Epstein-Barr virus-related lymphoproliferative disease. Routes of administration were also discussed. It was concluded that the development of hyperimmunes faces numerous obstacles. It was agreed that the use of hyperimmunes in clinical trials must be standardised; clinical trials must be large enough to have sufficient power to demonstrate efficacy with clear-cut end-points, and means need to be developed, in conjunction with regulatory agencies, for the feasible evaluation of combination products. However, progress in all these aspects will provide a wide range of hyperimmunes for future use.

Piercing is defined as puncturing an organ in order to place a jewel in the perforated site. There is hardly any external organ in the human body that has escaped piercing. The origin of piercing traces back to the dawn of human history. Piercing is performed for decorative or symbolic purposes. Many different medical specialists are confronted with the increasingly popular practice of body piercing in their daily practice. Until recently body piercing was mainly confined to the ears and/or nose. In the last few years there has been a significant increase in the prevalence of body piercing. There are a lot of side effects, among them especially infections. The most important bacteria cultivated from such patients are Staphylococcus aureus and group A streptococci and Pseudomonas aeruginosa. Viruses which can be transmitted by piercing are especially hepatitis B virus and hepatitis C virus. Besides local complications also systemic infections (sepsis, endocarditis) occur. The main aspects of diagnostics, therapy and prevention are discussed.

With the accumulation of orthotopic liver transplantation (OLT) recipients, an increased number of patients with graft failure need retransplantation (re-OLT). This study was undertaken to examine our clinical experience of re-OLT for patients with poor graft function after primary transplantation at a single center. We analyzed retrospectively, the clinical data of 32 re-OLTs in 31 patients at our center from January 2004 to February 2007, including indications and causes of death, timing of retransplantation, and surgical techniques. The indications included bile leak (2 cases), biliary stricture (16 cases), recurrence of hepatocellular carcinoma (HCC) (5 cases), hepatic artery stenosis (4 cases), hepatic artery thrombosis (HAT) (2 cases), and hepatitis B recurrence (3 cases). The rate of re-OLT was 4.29%. All patients underwent modified piggyback liver transplantations with cadaveric allografts. No intraoperative mortality and acute rejection occurred. Overall, 17 of 31 patients (54.8%) died after re-OLT with survival times ranging from 2 weeks to 28 months. Another 14 patients were cured with survival times of 4 to 32 months. The perioperative mortality rate of patients who underwent re-OLT between 8 and 30 days after their initial transplantation was highest (66.7%). The most common cause of death after re-OLT was sepsis (47.1%), multiple-organ failure (17.6%), and recurrence of HCC (17.6%), whereas the majority of deaths posttransplantation were sepsis-related (54%) within 1 year. Re-OLT is the only therapeutic option for a failing liver graft. Proper indications and optimal operative time, advanced surgical procedures, reasonable individual immunosuppression regimens, and effective perioperative anti-infection treatments contribute to the improved survival of patients after re-OLT.

Melioidosis is endemic in Taiwan. It is caused by infection with Burkholderia pseudomallei. A prolonged course of oral eradication therapy to avoid relapse after an intensive intravenous therapy is recommended to treat melioidosis. Melioidosis with cardiac involvement is rare and is often combined with septicemia, for which the mortality rate is 20-60%. The initial clinical presentations of melioidosis mimic Mycobacterium tuberculosis infection, which is the most common etiology of bacterial pericarditis in Taiwan. We present a case of non-septicemic melioidosis that presented as non-suppurative cardiac tamponade and left subcarinal lymphadenopathy. Underlying diseases included hepatitis B-related liver cirrhosis and hepatocellular carcinoma. The patient was successfully treated with 2 weeks of intravenous ceftazidime and 12 weeks of oral doxycycline, trimethoprim-sulfamethoxazole, and amoxicillin/clavulanate. Melioidosis-related pericarditis should be considered in the differential diagnoses of bacterial pericarditis in Taiwan.

Auxiliary partial orthotopic liver transplantation (APOLT) or heterotopic auxiliary partial liver transplantation (HAPLT) was initially indicated for potentially reversible fulminant hepatic failure (FHF). We started auxiliary partial living donor liver transplantation (LDLT) for FHF in February 2002. Since then, 5 FHF patients (3 females and 2 males) underwent auxiliary partial LDLT: 3 cases of APOLT and 2 cases of HAPLT. All of them received a small-for-size graft: graft-to-recipient weight ratio (GRWR) < or = 1.0%. The etiologies of FHF were hepatitis B virus (HBV) in 1, Wilson's disease in 1, and unknown origin in 3 cases. Three were the acute type and 2 the subacute type of FHF. Median age was 45 years (range, 14-54 years). Blood type was identical in all cases. A left lobe graft was used in 4 instances and a right lobe graft in 1 case. Median GRWR was 0.74 (range, 0.42-0.85). Median follow-up was 42 months (range, 3 days to 70 months). Three of 5 patients (60%) were alive (at 42, 67, and 70 months) and 1 was free of immunosuppression after sufficient recovery of the native liver. Two cases succumbed: 1 at postoperative day 3 because of cytomegalovirus pneumonia and 1 at 10 months after APOLT because of sepsis. Complications were seen in all 5 patients: Relaparotomy for hemostasis in 3, decompression surgery of the abdominal cavity in 1, rehepaticojejunostomy in 1, and biliary strictures in 2 cases. Auxiliary partial LDLT may be a choice as an aid for a small-for-size graft in FHF.

Thousands of patients are awaiting liver transplantation, mainly owing to the lack of donors. The aim of this study was to analyze the characteristics of discarded livers from donors seeking to understand how to increase the number of grafts. A retrospective analysis of 1432 discarded donor livers was performed in the period between 1994 and 2007. Data were stored in a standardized database in accordance with expanded donor criteria. The average donor age was 35.2 years with; 67.7% male subjects and 20.9% over age 50 years. The main cause of donor discard was family refusal (46.6%), followed by cardiorespiratory arrest (CRA) in 28.3%, and surgeon discard (16.9%), principally owing to sepsis (24.5%). Vasopressor drugs were used in 97.2%. Alcoholism was detected in 44.56% and drug addiction in 12.4%. There was infections documented in 23.9% of records, mainly of the respiratory type (75%). Intensive care time was over 120 hours in 11.0%. Hepatitis B infection was detected in 22.5%, (n = 338), and hepatitis C in 3.5% (n = 593). Finally, there were losses due to hypotension in 45.7% (516/1130) and also loss due to CRA. As family refusal was the principal cause for discarding a donor, it is necessary to investigate the role of information about organ transplantation to increase acceptance.

Hepatitis B virus (HBV) and hepatitis C virus (HCV) infection are the most common and serious causes of liver damage in patients with chronic kidney disease (CKD). The natural histories of HBV and HCV infections in patients with CKD are not fully understood; however, recent evidence has emphasized the adverse effect of HBV and/or HCV infection on survival in this population. Chronic liver disease is the fourth most important cause of death after renal transplantation. The negative effect of HCV infection on survival among renal transplant recipients has been linked to liver dysfunction and extrahepatic complications, such as chronic glomerulonephritis, post-transplantation diabetes mellitus, chronic allograft nephropathy, and sepsis. The transmission of HCV by solid organ transplantation has been unequivocally demonstrated. Renal transplant recipients who receive kidneys from HCV-positive donors are at increased risk of death. Although several studies have shown that in patients with HCV infection and chronic renal failure renal transplantation is associated with better survival than is dialysis, recent clinical guidelines recommend that kidneys from HCV-infected donors should not be used in HCV-seropositive recipients without detectable HCV viremia. Monotherapy with conventional interferon has been suggested to be a useful treatment for hepatitis C infection in patients on dialysis. Although no evidence suggests that patients with CKD are more prone to suffer from hepatic toxic effects than individuals with normal kidney function, patients with CKD usually receive multiple medications; and drug interactions may, therefore, have a role in the pathogenesis of drug-induced liver disease in this population.

The risks of known and emerging transfusion-transmitted infections (TTIs) from reducing the current lifetime blood donation deferral for men who have had sex with men (MSM) to 1 or 5 years were compared to the risk from continuing to transfuse in the United States 12.5% of platelet doses as pooled whole-blood-derived (rather than single-donor) platelets. Assumptions made in mathematical models and blood donor/transfusion studies of the risks of TTIs since 2000 were evaluated. The number of HIV, hepatitis B virus, or hepatitis C virus TTIs from reducing the MSM deferral to 1 year is, respectively, 0.88, 2.94, or 66.9, many more than 10 times smaller than the risk from pooled platelets. If erroneous release of HIV-positive units (a risk independent of a donor's source of infection) is not considered, the MSM risk is 1 HIV-infectious donation per 17 to 56 million MSM donations. Any purportedly increased risk of human herpesvirus-8 transmission from MSM donors is far smaller than the risk of transfusion-associated sepsis from pooled platelets. Single-donor platelets from MSM after 5 years' abstinence are as safe or 5 times safer than our current pooled platelets--if the next TTI to emerge were transmitted, respectively, sexually or by another route. Thus, acceptance of MSM as blood donors after 1 or 5 years' abstinence may result in a postulated increase in risk that is so much smaller than the currently tolerated transfusion risk and so small in absolute terms that the ethical question of fairness to the MSM group justifies the change in policy.

The most common cause of liver disease in patients with chronic kidney disease (CKD) remains infection by hepatitis B virus (HBV) and/or hepatitis C virus (HCV). The adverse effects of HBV and/or HCV infections upon survival in patients with CKD have been repeatedly confirmed. An excess risk of death in HBsAg positive or anti-HCV antibody-positive patients may be at least partially attributed to chronic liver disease with its attendant complications. A negative impact of HCV infection on survival after renal transplantation has been linked to extrahepatic complications, including chronic glomerulonephritis, sepsis, chronic allograft nephropathy, post-transplantation diabetes mellitus, and abnormal metabolism of calcineurin-inhibitors. Transmission of HCV infection by grafts from HCV-infected donors has been unequivocally demonstrated. Registry analyses suggest that recipients of kidneys from anti-HCV antibody positive donors are at increased risk of mortality. Renal grafts from HCV-infected donors should be restricted to viremic anti-HCV positive recipients. Several drugs have been recently licensed for therapy of HBV infection but availabledata in patients with CKD is mostly limited to experience with lamivudine. The standard of care for hepatitis C infection in patients on regular dialysis is monotherapy with conventional interferon, according to recent guidelines. Only dire circumstances justify interferon use after renal transplantation.
