Fatal sclerosing peritonitis associated with primary effusion lymphoma after liver transplantation: a case report.

Sclerosing peritonitis (SP) after liver transplantation has been described in 10 cases in the literature. The etiology is still unknown; however, SP is considered a consequence of chronic irritation and inflammation. It can be classified as primary (idiopathic) or secondary form. Although pathologically benign, it has a negative course, resulting in unrelenting abdominal pain, small bowel obstruction, malnutrition, and death. Posttransplantation lymphoproliferative disease (PTLD) is one of the leading causes of late death. Its development is related to complex interactions between immunosuppressive drugs and environmental agents. Primary effusion lymphoma (PEL) as an onset presentation of PTLD is relatively uncommon. Most examples of effusion-based PTLD have been secondary to widespread solid organ involvement and associated with Human herpes virus 8 (HHV-8) recurrence. Here in, we report a case of a 55-year-old man who rapidly developed refractory ascites and bacterial peritonitis at 1-year after orthotopic liver transplantation (OLT) with a fatal clinical course at the beginning of the second follow-up year after an uncomplicated liver transplantation due to cryptogenic cirrhosis. The diagnosis of HHV-8-positive lymphoma was established by postmortem examination with multiple solid localizations and massive dense fibrotic adhesions encompassing the small intestine, colon, liver, and porta hepatis without any involvement of body cavities.

First-line liver resection and salvage liver transplantation are increasing therapeutic strategies for patients with hepatocellular carcinoma and child a cirrhosis.

AIM: The present study focused on nine patients with hepatocellular carcinoma (HCC) associated with Child A liver cirrhosis undergoing first-line liver resection and salvage liver transplantation (SLT) for liver tumor recurrence. PATIENTS AND METHODS: Forty-six patients with HCC underwent liver transplantation (OLT); 37 (80.5%) were primary liver transplantations (PLTs) and 9 (19.5%) were SLTs. All patients who underwent SLT received minor transabdominal liver resections. RESULTS: The posttransplant 1-, 3-, and 5-year overall survival rates for SLT (88.9%, 88.9%, and 88.9%) were similar to those for PLT (78%, 62.7%, and 62.7%). Four (10.8%) patients in the PLT group had HCC recurrence, while there was zero recurrence in the SLT group. The 1-, 3-, 5-year disease-free survival rates for PLT (89%, 74%, and 74%) were similar to those for SLT (100%, 100%, and 100%). The 1-, 3-, 5-year disease-free survival rates after PLT were 89%, 74%, and 74%, and after SLT were 100%, 100%, and 100%, respectively. The operative mortality, intraperioperative bleeding, operative time, intensive care unit stay, in-hospital stay, and overall incidence of postoperative complications were similar in the two groups. CONCLUSIONS: In our experience, SLT for HCC is a feasible procedure with similar results in terms of overall survival, disease-free survival, and postoperative complications to those reported for patients who underwent PLT at our institute. An important role exists for SLT as shown by the fact that such a strategy has been used in the 20% of the patients undergoing OLT for HCC.

[Acute liver toxicity of antiretroviral therapy (HAART) after liver transplantation in a patient with HIV-HCV coinfection and associated hepatocarcinoma (HCC)]. / Tossicità epatica acuta da terapia antiretrovirale (HAART) dopo trapianto di fegato in un paziente con coinfezione da HIV-HCV ed associato epatocarcinoma (HCC).

OLT in HIV infected patients still remains a challenging option requiring a careful monitoring of patients for HCV reinfection, drug interactions and antiretroviral toxicity. Severe adverse events due to HAART have been already reported for post exposure prophylaxis in HIV infected patients. Here we report a case of liver graft toxicity related to HAART in a HIV-HCV co-infected patient (46 yrs-male) with associated a small HCC transplanted with a marginal liver graft. The patient had pre-OLT plasma HIV 1-RNA levels undetectable and CD4+ T-cell count of > 200 cells/microL for 6 months. At day 2 a severe graft dysfunction was observed (AST 1570 U/L, ALT 2180 U/L, BIL tot 8.3 mg/dL, BIL Dir 6.6 mg/dL and PT 35%--INR 2.5). Doppler scan showed hepatic artery always patient. Later the postoperative in-hospital course was complicated by tense ascites and severe cholestasis. Serum bilirubin reached 42 mg/dL in day 12. Hypertransaminasemia ended at day 15 while cholestasis ended after 46 days. Tacrolimus was reintroduced at day 7. A liver biopsy 10 after OLT showed severe intrahepatic cholestasis, centrolobular necrosis and macrovesicular steatosis (30%). The patient was discharged 48 days after OLT with good liver function. After seven months HIV-RNA is still undetectable and HAART has not been restarted. We believe that the early complications we observed may be attributed to a sudden increase in plasma concentration of antiretroviral drugs secondary to drug redistribution from peripheral tissues and hepatic clearance deficiency after OLT. Although a pre-OLT withdrawal of HAART seems unjustified a delayed re-introduction of HAART or the use of less hepatotoxic drugs may be advisable.

Resection and transplantation: evaluation of surgical perspectives in HIV positive patients affected by end-stage liver disease.

PURPOSE: The aim of this study was to evaluate the opportunity of surgical treatment in terms of liver resection or liver transplantation in HIV positive patients affected by an end stage liver disease that referred to our liver unit. METHODS: Among 1350 outpatients who referred to our liver unit from January 2002 to September 2003, thirty-two (2,4%) were HIV positive. The routes of transmission of the viral infection, the related co-infections and the underlying liver disease were recorded. The therapeutic pathway was analysed. The kind and the duration of the surgical procedures were assessed. RESULTS: Fourteen (44%) of these thirty-two patients were not suitable for surgical treatment. Surgery was planned in 9 of 32 HIV positive patients (28%). Four patients (12%) were submitted to liver resection and OLT was performed in five patients (15%). Hepatocellular Carcinoma was present in 4 (44%) of the HIV positive patients considered for surgery. CONCLUSIONS: In conclusion in our centre the 28% of HIV positive out patients had the opportunity to receive a surgical treatment. The candidate to this surgery is mostly young, HCV and/or HBV coinfected and affected by HCC in 44% of cases.

Locoregional versus general anesthesia in carotid surgery: is there an impact on perioperative myocardial ischemia? Results of a prospective monocentric randomized trial.

PURPOSE: The incidence of cardiac morbidity and mortality in patients who undergo carotid surgery ranges from 0.7% to 7.1%, but it still represents almost 50% of all perioperative complications. Because no data are available in literature about the impact of the anesthetic technique on such complications, a prospective randomized monocentric study was undertaken to evaluate the role of local anesthesia (LA) and general anesthesia (GA) on cardiac outcome. METHODS: From November 1995 to February 1998, 107 patients were classified by the cardiologist as cardiac patients (IHD; history of myocardial infarction, previous myocardial revascularization procedures, or myocardial ischemia documented by means of positive electrocardiogram [ECG] stress test results) or noncardiac patients (NIHD; no history of chest pain or negative results for an ECG stress test). The patients were operated on after the randomization for the type of anesthesia (general or local). Continuous computerized 12-lead ECG was performed during the operative procedure and 24 hours postoperatively. The end points of the study were ECG modifications (upsloping or downsloping more than 2 mm) of the sinus tachycardia (ST) segment. RESULTS: Fifty-five patients were classified as IHD, and 52 were classified as NIHD. Twenty-seven of the 55 IHD patients (49%) and 24 of 52 NIHD patients (46%) were operated on under GA. Thirty-six episodes of myocardial ischemia occurred in 22 patients (20.5%). Episodes were slightly more frequent (58%) and longer in the postoperative period (intraoperative, 10 +/- 5 min; postoperative, 60 +/- 45 min; P <. 001). As expected, the prevalence of myocardial ischemia was higher in the group of cardiac patients than in noncardiac group (15 of 55 patients [27%] vs 7 of 52 patients [13%]; P <.02). By comparing the two anesthetic techniques in the overall population, we found a similar prevalence of patients who had myocardial ischemia (GA, 12 of 52 [23%]; LA, 10 of 55 [18%]; P = not significant) and a similar number of ischemic episodes per patient (GA, 1.5 +/- 0.4; LA, 1.8 +/- 0.6; P = not significant). Episodes of myocardial ischemia were similarly distributed in intraoperative and postoperative periods in both groups. It is relevant that under GA, IHD patients represent most of the population who suffered myocardial ischemia (83%). On the contrary, in the group of patients operated on under LA, the prevalence was equally distributed in the two subpopulations. CONCLUSION: The results confirm the different hemodynamic impact of the two anesthetic techniques. Patients who received LA had a rate of myocardial ischemia that was half that of patients who had GA. The small number of cardiac complications do not permit us to make any definitive conclusion on the impact of the two anesthetic techniques on early cardiac morbidity, but the relationship between perioperative ischemic burden and major cardiac events suggests that LA can be used safely, even in high-risk patients undergoing carotid endarterectomy.

Hemodynamic and metabolic effects of transjugular intrahepatic portosystemic shunt (TIPS) during anesthesia for orthotopic liver transplantation.

Recently, the transjugular intrahepatic portosystemic shunt (TIPS) has been advocated as a safe bridge to orthotopic liver transplantation (OLT). We retrospectively studied 53 consecutive cirrhotic patients who underwent OLT: 27 patients with TIPS were compared to 26 controls. Hemodynamic and oxyphoretic data (Fick method) were collected during six phases of OLT. There were no significant differences in demographic data and Child-Pugh class, nor in surgical time and blood product requirements before the anhepatic phase between TIPS patients and controls. In the TIPS group, we observed a marked hyperdynamic profile with a lower systemic vascular resistance index, higher cardiac index, and depressed oxygen consumption before native liver removal. During the same period, the TIPS group developed a greater acidosis and was treated with a larger amount of NaHCO3. Following the anhepatic phase, no differences between the two groups were detected. All transplantations were successful, and no complications related to TIPS were observed. These results seem to be the consequence of a reduced liver function reserve with a direct hemodynamic effect due to the TIPS.
