RESUMEN
OBJECTIVES: Interferon-alpha (IFN) may have undesirable effects on a functioning graft. The aim of this study was to evaluate IFN treatment in kidney transplant candidates during the hemodialysis period as well as the results after transplantation. METHODS: A total of 29 noncirrhotic hemodialysis patients with chronic hepatitis C virus (HCV) infection (based on long-term rise in ALT, HCV serology, HCV RNA by polymerase chain reaction methods, and histological evidence) were included. Tolerability to IFN treatment, pre- and posttransplantation therapeutic results, and long-term outcome were recorded. IFN regimen consisted of 3 million units (MU) times per week after hemodialysis sessions for 6 months, followed by 1.5 MU after each hemodialysis session for an additional 6 months. All patients gave informed consent for participation. RESULTS: IFN therapy was fairly well tolerated. Adverse effects due to IFN toxicity, renal disease, or causes related to the immunological properties of IFN were observed in 24% of patients. At the end of treatment, ALT had normalized in 23/28 patients (82.1%), and HCV RNA had cleared in 23/28 patients (82.1%). During follow-up, HCV RNA was persistently negative in 18 patients (64%, including transplant recipients). A total of 14 patients (nine HCV RNA-negative) received a kidney transplant. Mean follow-up after the procedure was 41 +/- 28 months. In all, 12 patients had a functioning graft, one had acute vascular rejection, and one died of carcinoma. All transplanted patients maintained normal ALT levels, and eight remained HCV RNA-negative. CONCLUSIONS: Treatment results in our study population were better than those observed in the general population. The long-term response achieved, which was maintained after transplantation, supports the use of IFN for HCV hepatitis in kidney transplant candidates under hemodialysis.

BACKGROUND: Ubiquitous mutations in microsatellite DNA sequences define a specific type of genetic instability, termed microsatellite instability (MSI). Various approaches have been used to identify the presence and degree of MSI. To define standard diagnostic criteria for MSI, we developed and tested a mathematical model. METHODS: We designed an algorithm for the efficient characterization of MSI and used it to analyze data on six microsatellite markers in colorectal carcinoma and normal tissues from 415 patients. Theoretical models considering one, two, or three populations were tested against the data collected. RESULTS: The observed frequencies of MSI in our series of samples best fit a two-population model, stable and unstable, defined by instability in two or more of four to six markers analyzed. MSI was observed in 7.5% of the tumors. The misclassification rate was less than 5% when any four loci were analyzed and less than 1% when the six markers were used. A stepwise strategy, consisting first of a bulk screening of two loci and then a second screening of two to four additional markers, provided excellent sensitivity (>/=97%) and specificity (100%). Tumors with MSI had distinctive genetic and clinicopathologic features, including better patient survival. CONCLUSION: To assess the presence of MSI in colorectal cancer, we have developed a simple, sensitive, and specific approach based on the apparent good fit of the data to a two-population model. Its application to a prospective series of patients with colorectal carcinomas demonstrates that the presence of MSI characterizes a subset of less aggressive tumors.

BACKGROUND: We present the experience of the liver transplantation program at the Hospital of Bellvitge with 500 transplantations performed during 15 years, to describe changes in liver transplantation observed throughout the time and to analyze the long term results. PATIENTS AND METHOD: Five groups each one including 100 consecutive transplantations are studied. RESULTS: The main indications were hepatocellular carcinoma (23%), alcoholic cirrhosis (22.8%), and post-hepatitis C cirrhosis (18.8%). Sixty-five retransplantations were performed in 59 patients (13%), being the more frequent indications arterial thrombosis (13 patients) and primary nonfunction of graft (10 patients). In 10 patients a hepatorenal transplantation was performed. In group I, the most frequent donor cause of death was cranial traumatism (80%), while in group V it was the vascular pathology (52%). There were other significative differences between these groups of patients (I vs V): patients with stage 2 or 3 from UNOS status (45 vs 19%), blood use (29.6 [26] vs 4.6 [5.3] PRBC), ICU stay (13 [13] vs 7.4 [11] days), hospital stay (40 [52] vs 23.7 [17] days), rejection rate (46 vs 20%) and primary graft nonfunction (9 vs 3%). However, the infection rates (48 vs 54.5%) and biliary tract complications (26 vs 20%) have not shown statistically significant differences. Actuarial one and 5-year survival are 83 and 70% respectively. CONCLUSIONS: An important and progressive improvement of liver transplantation results has been observed. However, de novo tumours, hepatitis C virus recurrence and chronic rejection can limit long term results.

BACKGROUND: Experimental studies have shown that 21-aminosteroids (21-A) are powerful inhibitors of superoxide-mediated iron-dependent lipid peroxidation. This study was aimed at determining how far the blocking effect of one of these substances (lazaroid U74389G) on lipid peroxidation protects intestinal grafts morphologically and biologically in a heterotopic transplant model (SBT) in rats. ANIMALS AND METHODS: Heterotopic LEW were performed using Ringer lactate (4 degrees C) as preservation solution. In Group 1 (n = 7) the donor and recipient animals received 3 and 6 mg/kg of the 21-A U74389G, respectively. Group 2 (n = 7) received the same doses of the vehicle of the drug. Sham group underwent only a laparotomy. Bacterial translocation (BT) was determined in mesenteric lymph nodes (MLN), liver (L), and spleen (S) 60 min after reperfusion. Tissue myeloperoxidase (MPO), malondialdehyde (MDA), and percentage conversion xanthine dehydrogenase/xanthine oxidase (XD/XO) were also determined in the ileal graft. Histological damage was graded according to Park's classification. RESULTS: Tissue MDA (nmol/mg prot) was significantly lower in Group 1 (0.53 +/- 0.09) than in Group 2 (3.66 +/- 1, P < 0.05) and showed levels similar to those of the sham-operated group (0.40 +/- 0.05). Injury grades were also significantly different in both study groups (Group 1, 0-1; Group 2, 2-3, P < 0.05). BT (log CFU/g tissue) in Group 1 were MLN, 0; L, 0.36; and S, 0. In Group 2, MLN, 1.07; L, 0.81; and S, 1.49 (P < 0.05 in MLN). Increase in MPO activity (U/g prot) in comparison with sham-operated animals was similar in the two study groups (Group 1, 1.49 +/- 0.58; Group 2, 1.22 +/- 0.46; Sham, 0.34 +/- 0.37 (P < 0.05 1,2 vs sham). Conversion of XD to XO was unaffected by the supplementation of the drug. CONCLUSION: 21A U74389G inhibits lipid peroxidation, protects intestinal graft, and reduces BT after heterotopic SBT in rats.

The aim of this study was to evaluate the tolerance of normothermic liver ischemia with different degrees of hepatic function in cirrhotic rats. Liver cirrhosis was induced by administering carbon tetrachloride (CCl4) in water solution to male Wistar rats. Hepatic function was graded using the plasma levels of antithrombin III, albumin, and bilirubin and the presence of ascites. Rats were distributed in four groups: noncirrhotic (control group), compensated cirrhosis (group A), decompensated cirrhosis (group B), and decompensated cirrhosis with ascites (group C). Groups A, B, and C were significantly different in all four parameters studied (P < .003). Subtotal liver ischemia was performed for periods of 0, 30, 45, 60, and 75 minutes. At the end of the procedure, the nonischemic lobes were resected. Postoperative evolution of alanine aminotransferase, aspartate aminotransferase, and bilirubin levels was also recorded. Survival rates after the same periods of ischemia were statistically different (P < .05): control group, 7 of 7 after 45 minutes (100%), 7 of 7 after 60 minutes (100%), and 4 of 9 after 75 minutes (44%); group A, 7 of 7 after 45 minutes (100%) and 1 of 7 after 60 minutes (14%); group B, 7 of 7 after 0 minutes (100%), 5 of 7 after 30 minutes (71%), and 1 of 7 after 45 minutes (14%); and group C, 0 of 5 after 0 minutes (0%) and 1 of 7 after 30 minutes (14%). No differences were found in the postoperative course of transaminases. However, bilirubin levels found 24 hours and 7 days after ischemia were significantly greater in cirrhotic rats, and this was directly related to the degree of hepatic insufficiency (P < .001). Histological examination of the livers exposed to CCl4 showed features of liver cirrhosis with ductal proliferation. The ischemia time tolerated by cirrhotic rat livers is shorter than the time tolerated by normal rats. Tolerance to hilar vascular occlusion depends on the degree of hepatic insufficiency. Rats with decompensated cirrhosis and ascites do not tolerate any surgical procedure.

Cumulative recurrence after surgical resection for hepatocellular carcinoma (HCC) is very high. Several retrospective analyses have shown that liver transplantation was more effective than resection for patients with HCC at early tumor stages. Consequently, in January 1990, we decided to prospectively indicate orthotopic liver transplantation (OLT) as the first surgical treatment for small, localized HCC in cirrhotic patients without nodal involvement independently of the degree of liver function. The aim of this prospective cohort study was to analyze prognosis, recurrence rate, and survival after liver transplantation in patients in whom the main indication was HCC with cirrhosis. Thirty-eight patients in whom the main indication for liver transplantation was HCC and hepatic cirrhosis were compared with 136 transplantations because of cirrhosis without tumor, performed in our unit from January 1990 to December 1995. HCC arising in noncirrhotic livers and those incidently discovered after OLT were excluded from the study. Chemoembolization using doxorubicin, lipiodol, and Gelfoam was performed before OLT in 31 patients with good liver function. There were no differences in gender, but HCC patients were older (57 +/- 7 vs. 50 +/- 10 years [P < .001]). Liver function was better in HCC (Child-Pugh score: 6.9 +/- 2 vs. 8.6 +/- 1.8; P < .001), and hepatitis C virus antibody was positive in 31 (82%) vs. 51 (37%) (P < .007). Seven tumors had bilobar involvement (18%). Capsule was present in 22 (58%). The mean size of the tumor was 3.4 +/- 2 cm. Seventeen tumors (45%) were larger than 3 cm, and 4 (11%) were larger than 5 cm. The average number of nodules was 2 +/- 1. The tumor-node-metastasis stage of the tumors was pT1 in 6 patients (16%), 11 were pT2 (29%), 12 were pT3 (31%), and 9 were pT4 (24%). Seven patients were retransplanted in the HCC group (18%) and 19 (14%) in the nontumor group (not significant). Tumor recurrence was detected in three patients (8%). One, 3-, and 5-year survival rates were 82% vs. 79%, 75% vs. 71%, and 63% vs. 68%, respectively, for patients with and without HCC, and no differences were found between the two groups (P = .84). Survival was significantly reduced in patients with a macroscopic vascular invasion and tumors greater than 5 cm in diameter. Recurrence and mortality after liver transplantation in cirrhotic patients with carefully selected HCC are similar to the results in cirrhotic patients without tumor.

OBJECTIVE: We conducted a prospective study to determine the efficacy of iodized-oil enhancement in CT for preoperative assessment of the T factor of the TNM classification in patients with hepatocellular carcinoma (HCC). SUBJECTS AND METHODS: Iodized-oil CT was performed as a part of preoperative staging in 28 patients with HCC. We determined the radiologic T factor. Pathologic correlation was obtained after orthotopic liver transplantation (n = 25) or autopsy (n = 3), and the histologic T factor was determined. RESULTS: The sensitivity of iodized-oil CT accurately distinguishing between stage-T4 tumors and tumors in stages T1-T3 was 88% (7/8) with a positive predictive value of 100% (7/7). CONCLUSION: Iodized-oil CT is useful for preoperatively assessing the T factor of the TNM classification in HCC, and it improves the accuracy of radiologic staging. Iodized-oil CT can help to better patients with HCC for orthotopic liver transplantation.

We describe the development of a lymphoma in a liver allograft shortly after orthotopic liver transplantation. Aspiration and core biopsies of the nodule were persistently negative so that a diagnosis could not be made until the patient underwent retransplantation, when examination of the liver resection specimen revealed a B-cell lymphoma. Using a rapid technique based on the polymerase chain reaction, we were able to demonstrate that the tumor was of donor origin.

Two cases of acute abdomen--because of acute appendicitis and paralytic ileus--due to cytomegalovirus infection in AIDS patients are reported. In both patients evolution was subacute and cytomegalic inclusions were seen in the histologic examination of the surgical samples. The two patients died after surgery. The possibility of cytomegalovirus infection must be kept in mind in AIDS patients who undergo urgent abdominal laparatomy and early treatment should be instituted.

Transcatheter arterial chemoembolization with lipiodol and adriamycin was performed in 46 patients with hepatocellular carcinoma (HCC). In 27, this procedure was followed by selective arterial embolization using gelatin sponge particles. Surgical resection was carried out in 5 cases and 13 patients were transplanted (OLT). The aim of the study was to analyze the survival and degree of tumor necrosis. In the nonsurgical group the overall survival was 67% after 24 months in the OKUDA I stage, 31% after 20 months in the OKUDA II stage and 25% after 6 months in the OKUDA III stage. For the patients who underwent surgery, survival was 38% after 20 months in 5 patients who were resected and 72% after 24 months in 13 patients who were transplanted. Transcatheter arterial chemoembolization improves survival in patients who are not operated on, and can be used as a complementary treatment for patients who undergo surgery. A full tumor necrosis was observed in well encapsulated tumors.

We have examined immunohistochemically the presence of human chorionic gonadotrophin (hCG) in 29 esophageal carcinomas: 24 squamous cell carcinomas, 2 adenocarcinomas, 2 adenoid cystic carcinomas and 1 adenosquamous carcinoma. In hCG-positive tumors, the presence of human placental lactogen (hPL) and pregnancy-specific beta-1 glycoprotein (SP-1) was also assessed. HCG immunoreactive cells were found in 5 squamous cell carcinomas (21%) and in none of 5 non-squamous cell tumors. The hCG positive cells were found in the most infiltrating areas of the tumors where poorly differentiated and pleomorphic cells predominated. The positive tumors were 4 poorly differentiated (31%) and one moderately differentiated carcinoma (12%). Four out of 10 cases (40%) with lymph node metastases had hCG in the primary tumor, whereas only one out of 11 cases (9%) without metastases was hCG positive. HPL and SP-1 were found in two cases. These placental proteins were detected in similar areas than hCG but the number of hPL and SP-1 immunoreactive cells was lower than hCG positive cells. SP-1 was also seen in areas of squamous cell differentiation negative for hCG. None of these two cases showed trophoblastic differentiation.

Hepatic transplant has recently undergone ostensible changes in post operative mortality. The present study investigates whether this improvement in survival is associated with a subjective and objective improvement in quality of life. Nineteen patients were evaluated preoperatively and/or postoperatively with a questionnaire (Nottingham Health Profile). The results showed a remarkable improvement in the quality of life of these patients, which became more marked after three months. The readaptation to work was good, considering the current state of our society. The mean yearly hospital stay was 12 days, distributed in three admissions mainly to perform hepatic biopsy.
