[Basiliximab in the treatment of acute steroid-resistant rejection after liver transplantation]. / Basiliximab en el tratamiento del rechazo celular agudo resistente a los corticoides postrasplante hepático.

We present the case of a liver transplant recipient with alcoholic liver cirrhosis and early-stage hepatocellular carcinoma who developed biopsy-proven acute steroid-resistant rejection 3 months after liver transplantation. After the failure of immunosuppressive therapy with intravenous boluses of 6-methyl-prednisolone and switching of the immunosuppressive regimen to tacrolimus plus mycophenolate mofetil, two doses of intravenous basiliximab were administered four days apart. Clinical, analytical, and biopsy-proven histological response was complete. No basiliximab-related adverse events were detected. Basiliximab may represent an alternative in liver transplantation immunosuppression to treat acute steroid-resistant rejection, without increasing the incidence of infections, neoplasms, or other adverse events, as shown by this case.

Efficacy of intravenous iron in treating iron deficiency anaemia in patients with inflammatory bowel disease. Are there predictors of response?

INTRODUCTION: In inflammatory bowel disease (IBD) iron deficiency anaemia (IDA) is a very common disorder. Until recently,oral iron has been the mainstay therapy, nevertheless it has been associated with intolerance and noncompliance. Therefore, the goal of our study was to evaluate the efficacy of intravenous iron in IDA in IBD patients and the secondary aim was to investigate whether other potencial factors could influence in the response to the treatment. DESIGN: An open-label, prospective, consecutive, single centre study. MATERIAL AND METHODS: We performed our study in patients with ulcerative colitis (UC) or Crohn´s disease (CD) with severe anaemia or intolerance with oral iron. All of them received intravenous sacarose iron and did biochemistry profile with hemoglobin (Hb). Moreover, the correlation with other variables was studied: age,sex, smoking habit, IBD type, previous surgery and type of surgery and other treatments. Response was defined as Hb increase of ≥ 2 g/dL or normalization of the levels. RESULTS: Fifty-four patients were included into the study, 34(63%) with UC y 20 (37%) with CD, 18 (33.3%) men and 36 wo-men (66.6%) and the average was 48 +/- 14 years. The total proportion of responders was 52% (SD +/- 05); 43% of the patients reached Hb ≥ 2 g/dl and y 9% of them normalized Hb. Only the utilization of 5-ASA was associated with low response to iron treatment (p < 0.05). CONCLUSIONS: Our study suggests that response to intravenous iron is achievable in the majority of patients with IBD and severe IDA or intolerance treatment with oral iron. Moreover, the patients with consumption of 5-ASA could had less response to the treatment.

[Portal vein thrombosis]. / Trombosis portal.

Thrombosis of the splenoportal axis not associated with liver cirrhosis or tumoral disease is the second cause of portal hypertension in the western world. In up to 60% of cases, an underlying systemic prothrombotic disorder can be identified as an etiological factor. One third of cases are caused by local factors and the coexistence of several entities is not unusual. Therefore, an etiologic diagnosis is essential in these patients. Early anticoagulation therapy in the acute phase of thrombosis of the splenoportal axis significantly affects the probability of recanalization and consequently the prognosis of these patients. In the chronic phase of splenoportal thrombosis (or portal cavernoma), the symptoms are caused by the complications of established portal hypertension. To date, anticoagulation therapy is limited to patients in whom an underlying prothrombotic disorder has been demonstrated.

[Intraductal papillary mucinous tumor: diagnostic and therapeutic approach]. / Tumor papilar, mucinoso e intraductal: abordaje diagnóstico y terapéutico.

Primary cystic pancreatic neoplasms are rare tumors, with an approximate prevalence of 10% of cystic pancreatic lesions. Most of these lesions correspond to mucinous cystic neoplasm, serous cystoadenoma and intraductal papillary mucinous tumor (IPMT). IPMT is characterized by diffuse dilatation of the main pancreatic duct and/or side branches with inner defects related to mucin or tumor, or mucin extrusion from a patent ampulla. IPMT has a low potential for malignancy, with a low growth rate, a low rate of metastatic spread and postsurgical recurrence. Over the last few years, major advances have been made in the diagnostic and therapeutic management of this tumor.
