RESUMO

INTRODUCTION: Corticosteroids are still the standard first-line treatment for immune thrombocytopenic purpura (ITP). As second-line therapy, splenectomy and Rituximab are both recommended. The aim of our study was to compare the efficacy of Rituximab to splenectomy in persistent or chronic ITP patients. METHODS: Between January 1999 and March 2015, we retrospectively selected all consecutive patients who underwent an ITP second-line treatment: Rituximab or splenectomy. The distinction between open (OS) and laparoscopic splenectomy (LS) was analyzed. Primary outcome was composite: hospitalization for bleeding and/or thrombocytopenia and death from hemorrhage or infection. Secondary outcomes were based on response (R) and complete response (CR) rates as defined by the American Society of Hematology. RESULTS: Ninety-six patients were included: 30 patients received Rituximab, 37 underwent OS, and 29 underwent LS. The follow-up was 30, 60, and 120 months in Rituximab, LS, and OS groups, respectively. At 30 month, the primary outcome-free survival rate was higher in splenectomy groups (84% for OS, 86% for LS) than Rituximab group (47%) (P = 0.0002). Similarly, at 30 month, R and CR rates were higher for OS (86.5% and 75.7%, respectively) and LS groups (93.1% and 89.7%) than Rituximab (46.7% and 30%) (P = 0.0001). Moreover, R rates remained elevated at 60 month for OS and LS groups (83.7% and 89.6% respectively) and 78.4% at 120 month for OS group. CONCLUSION: We observed that splenectomy for ITP second-line treatment was more effective than Rituximab regarding maintenance of R, CR, and overall response rates. OS and LS had similar efficacy.

RESUMO

BACKGROUND: Liver transplantation is the most extreme form of surgical management of patients with hepatic trauma, with very limited literature data supporting its use. The aim of this study was to assess the results of liver transplantation for hepatic trauma. METHODS: This retrospective analysis based on European Liver Transplant Registry comprised data of 73 recipients of liver transplantation for hepatic trauma performed in 37 centers in the period between 1987 and 2013. Mortality and graft loss rates at 90 days were set as primary and secondary outcome measures, respectively. RESULTS: Mortality and graft loss rates at 90 days were 42.5% and 46.6%, respectively. Regarding general variables, cross-clamping without extracorporeal veno-venous bypass was the only independent risk factor for both mortality (P = 0.031) and graft loss (P = 0.034). Regarding more detailed factors, grade of liver trauma exceeding IV increased the risk of mortality (P = 0.005) and graft loss (P = 0.018). Moreover, a tendency above the level of significance was observed for the negative impact of injury severity score (ISS) on mortality (P = 0.071). The optimal cut-off for ISS was 33, with sensitivity of 60.0%, specificity of 80.0%, positive predictive value of 75.0%, and negative predictive value of 66.7%. CONCLUSIONS: Liver transplantation seems to be justified in selected patients with otherwise fatal severe liver injuries, particularly in whom cross-clamping without extracorporeal bypass can be omitted. The ISS cutoff less than 33 may be useful in the selection process.

RESUMO

BACKGROUND: Oxygen consumption at peak exercise (peak VO2) is the most accurate index of aerobic capacity (AC), which reflects the physical condition of an individual and is currently considered the gold standard for cardiorespiratory fitness. Evaluation of peak VO2 to identify high-risk candidates for liver transplantation (LT) may represent an interesting approach. The aims of this study were (a) to describe AC and identify factors independently associated with peak VO2; (b) to analyze the prognostic value of peak VO2 in patients referred for preliminary evaluation of LT; and (c) to provide preliminary data on the influence of peak VO2 on length of hospitalization and the need for oxygen support after LT. RESULTS: Peak VO2 was determined in patients referred for preliminary evaluation for LT. One hundred thirty-five candidates were included. More than half had severe alterations in peak VO2. Age, gender, model-for-end-stage liver disease (MELD) score, tobacco use, and hemoglobin were independently associated with peak VO2. Candidates with severe alterations in peak VO2 had a lower 1-year survival than others. Model-for-end-stage liver disease score and peak VO2 were independently associated with survival. In patients with a MELD above 17, those with severe alterations of peak VO2 AC had lower 1-year survival than the others. Among patients who underwent LT, those with severe impairment of peak VO2 showed a trend toward a higher mean length of hospitalization after LT and had significantly longer need for oxygen support. CONCLUSIONS: Peak VO2 is severely impaired in candidates for LT and affects survival and post-LT course. Perioperative respiratory rehabilitation programs validated in lung and heart transplantation must be tested.
