Abstract
BACKGROUND The Amazon region is one of the main endemic areas of hepatitis delta in the world and the only one related to the presence of genotype 3 of the delta virus. OBJECTIVE To analyze the profile, mortality and survival of cirrhotic patients submitted to liver transplantation for chronic hepatitis delta virus and compare with those transplanted by hepatitis B virus monoinfection. METHODS Retrospective, observational and descriptive study. From May 2002 to December 2011, 629 liver transplants were performed at the Walter Cantídio University Hospital, of which 29 patients were transplanted due to cirrhosis caused by chronic delta virus infection and 40 by hepatitis B chronic monoinfection. The variables analyzed were: age, sex, MELD score, Child-Pugh score, upper gastrointestinal bleeding and hepatocellular carcinoma occurrence before the transplantation, perioperative platelet count, mortality and survival. RESULTS The Delta Group was younger and all came from the Brazilian Amazon Region. Group B presented a higher proportion of male patients (92.5%) compared to Group D (58.6%). The occurrence of upper gastrointestinal bleeding before transplantation, MELD score, and Child-Pugh score did not show statistical differences between groups. The occurrence of hepatocellular carcinoma and mortality were higher in the hepatitis B Group. The survival in 4 years was 95% in the Delta Group and 75% in the B Group, with a statistically significant difference (P=0.034). Patients with hepatitis delta presented more evident thrombocytopenia in the pre-transplantation and in the immediate postoperative period. CONCLUSION The hepatitis by delta virus patients who underwent liver transplantation were predominantly male, coming from the Brazilian Amazon region and with similar liver function to the hepatitis B virus patients. They had a lower incidence of hepatocellular carcinoma, more marked perioperative thrombocytopenia levels and frequent episodes of upper gastrointestinal bleeding. Patients with hepatitis by delta virus had lower mortality and higher survival than patients with hepatitis B virus.

Abstract
Platelet transfusion (PTx) has been identified as an important risk factor for morbidity and mortality after liver transplantation (LTx). Our aim was to evaluate the safety of therapeutic rather than prophylactic PTx policy in severe thrombocytopenic patients undergoing LTx. Recipients of LTx were divided into two groups: group I (GI) (n = 76) platelet count (PC) ≥ 50 × 10(9)/l and group II (GII) PC < 50 × 109/l (n = 76). Platelets were transfused following a thromboelastometry protocol and clinical signs of diffuse bleeding. Both groups were compared regarding hemoglobin (Hb), international normalized ratio (INR), fibrinogen level, blood loss (BL), blood products required, percentage of bloodless surgery, duration of mechanical ventilation, ICU stay, and vascular complications. Each group was further subdivided according to PTx into (GI NPTx and GII NPTx) with no platelet transfusion (NPTx) and (GI PTx and GII PTx) received PTx. These subgroups were further compared for some variables. Base line Hb was significantly higher while INR was significantly lower in GI.75% avoided PTx in GII. Comparisons of BL, packed red blood cells (PRBCs), and cryoprecipitate transfusion were insignificant. Fresh frozen plasma (FFP) transfusion was higher and the percentage of bloodless surgery was lower in GII. In GII, PC increased after start of surgery. Two cases of hepatic artery thrombosis in GI and one in GII were recorded. Recovery of platelets was quicker, and duration of mechanical ventilation and ICU stay was shorter in NPTx patients regardless the base line PC. Cut-off values of PC 30 × 10(9)/l (with sensitivity 73.7% and specificity 78.8%, p < 0.01), BL of 3750 ml in GI (sensitivity of 75% and specificity of 69%, p < 0.01) and of 3250 ml in GII (sensitivity of 84.2% and specificity of 87.7% (p < 0.01)) could indicate the need of PTx. With therapeutic approach, 75% of patients in GII could avoid unnecessary PTx with its hazards without excessive bleeding. PC in GII increased intraoperatively, PTx may lead to delayed recovery of platelets, increased duration of mechanical ventilation and ICU stay. The given cut-off values may help to guide PTx.

Abstract
BACKGROUND Whether splenectomy can be performed simultaneously during liver transplantation in patients with end-stage liver diseases complicated by hypersplenism remains controversial. This study aimed to compare the impact of simultaneous splenectomy on high- and low-risk liver transplant patients with end-stage liver diseases and severe hypersplenism. METHODS Forty-two patients with end-stage liver diseases complicated by severe hypersplenism who had undergone orthotopic liver transplantation were enrolled in this study. Splenectomy was performed in 19 of the patients. The 42 patients were grouped according to the risk of liver diseases and operations they received. Patients were considered to be at high-risk if they had at least one of the following conditions: preoperative prothrombin time >5 seconds, portal vein thrombosis, and severe perisplenitis. High-risk patients who had undergone splenectomy were classified into group A, whereas high-risk patients who had not undergone splenectomy were classified into group B. Low-risk patients who had undergone splenectomy were classified into group C, and low-risk patients who had spleen preservation were classified into group D. Operative time, intraoperative blood loss, postoperative bleeding, pulmonary infection, perioperative mortality, and postoperative platelet recovery were analyzed. RESULTS Operative time and intraoperative blood loss were greater in group A than in groups B-D (P<0.01), but there was no significant difference between groups C and D (P>0.05). In group A, 3 patients had postoperative bleeding, 5 had pulmonary infection, and 2 had perioperative mortality, which was higher than any other group, but postoperative bleeding, pulmonary infection, and perioperative mortality were similar to those in groups C and D. In patients undergoing simultaneous splenectomy, platelet counts recovered within 6 months after surgery. Thrombocytopenia was sustained in 3 of the 23 patients who did not undergo simultaneous splenectomy. CONCLUSION Splenectomy should be avoided during orthotopic liver transplantation in high-risk patients, but this procedure does not increase the operative risk in low-risk patients and may be a valuable method to ensure good postoperative platelet recovery.

Abstract
The platelet count (PC), the spleen size (SS), and the portal blood flow (PBF) have been independently studied in the perioperative period after orthotopic liver transplantation (OLT) for cirrhosis, but these parameters have not been described and analyzed in combination. We analyzed PC data and Doppler sonography measurements of SS and PBF from 125 adult patients before OLT and 1, 3, 6, 9, and 12 months after transplantation. A linear mixed model with fixed subject random intercepts was used. PCs increased significantly from 101.5 ± 68.5 × 10(9) /L before OLT to 162.4 ± 86 × 10(9) /L 1 month after OLT and remained stable for 1 year after the operation. PBF increased significantly from 619 ± 239 mL/minute before OLT to 1379 ± 491 mL/minute after OLT and remained stable during the first year. SS slowly decreased after OLT, but the decrease became significant only 9 months after the operation (13.8 ± 4.2 cm before OLT versus 11.7 ± 3.7 cm at 9 months, P < 0.05). The cirrhosis etiology did not influence the evolution of the parameters. With or without replication or interferon treatment before OLT, the hepatitis C group viruses did not influence PCs postoperatively. The evolution of SS was correlated to the evolution of PCs in the year after transplantation. In conclusion, PCs and PBF increase rapidly after OLT, whereas SS slowly decreases. The cirrhosis etiology does not influence the evolution of PCs. Thrombocytopenia and splenomegaly are 2 results of portal hypertension, but the rapid normalization of PBF does not completely or rapidly reverse these 2 phenomena.

Abstract
Thrombocytopenia is common after LT for pediatric end-stage liver diseases. Seventy-six pediatric patients (≤15 yr old) who underwent LDLT were evaluated for the incidence and predictive factors of post-transplant thrombocytopenia (PLT <100, 000/mm(3) ). The prevalence of thrombocytopenia at two wk and at 12 months post-transplant was 22/76 (28.9%) and 11/62 (17.7%), respectively. Thrombocytopenia at two wk after LDLT was significantly associated with age at transplant, preoperative PLT, GRWR, acute rejection, and CMV infection in univariate analysis. Moreover, preoperative PLT, GRWR, and acute rejection had a strong correlation in multivariate analysis. Thrombocytopenia at 12 months after LDLT was associated only with preoperative PLT. We also demonstrated that vascular complications caused thrombocytopenia and that successful treatment recovered the PLT. These results showed that, in addition to considering the preoperative PLT, post-operative monitoring of platelets is very helpful for the early detection of adverse events related to the graft liver in pediatric liver transplant patients.

Abstract
CONTEXT: Most patients subjected to liver transplantation presents hypersplenism, which is reversed after the operation. However, some patients remain with moderate to intense hypersplenism. OBJECTIVES: To study the effect of liver transplantation on platelet count in patients with hypersplenism. METHOD: Of a total of 233 patients who underwent liver transplantation, 162 were excluded from the present study because of occurrence of steroid-resistant rejection, absence of hypersplenism before the transplantation, absence of follow-up for at least 2 years or incomplete exams data. The electronic study protocols of the remaining 71 patients were reviewed to determine the demographics, etiology of cirrhosis, and results of pathologic examination of the explanted liver. Serial platelet count was obtained from the study protocol on the day before liver transplantation and 1, 2, 4, and 6 months and 1 year after liver transplantation. Statistical analysis was performed using the Student's t-test, chi-square test, and Spearman's correlation test. RESULTS: Posttransplant platelet count at all time intervals was significantly higher than the pretransplant value (P<0.001 for all time intervals). Thrombocytopenia was reversed (platelet count >100,000/mm³) in 58 patients (81.7%) 1 month after liver transplantation. Twelve patients (16.9%) remained with thrombocytopenia 1 year after liver transplantation. Three patients (4.2%) had recurrence of thrombocytopenia within 1 year after liver transplantation. There was no correlation between pretransplant platelet count and the Child-Pugh class or the MELD score. CONCLUSION: Liver transplantation reverses hypersplenism in most patients.

Abstract
Hepatitis C is the most common indication for orthotopic liver transplantation in the United States. Unfortunately, hepatitis C recurs universally in the transplanted liver and is the major cause of decreased graft and patient survival. The combination therapy of interferon and ribavirin has been shown to be the most effective therapy for recurrent hepatitis C. However, pre- and post-transplant hypersplenism often precludes patients from receiving the antiviral therapy. Splenectomy and partial splenic embolization are the two invasive modalities that can correct the cytopenia associated with hypersplenism. In this report we review the two treatment options, their associated outcomes and complications.
