ABSTRACT
BACKGROUND/AIM: Variceal bleeding is a life-threatening complication of portal hypertension with a high probability of recurrence. Treatment to prevent first bleeding or rebleeding is mandatory. The study has been aimed at investigating the effectiveness of endoscopic band ligation in preventing upper gastrointestinal bleeding in patients with portal hypertension and to establish the clinical outcome of patients. PATIENTS AND METHODS: We analyzed in a multicenter trial, the efficacy and side effects of endoscopic band ligation for the primary and secondary prophylaxis of esophageal variceal bleeding. We assigned 603 patients with portal hypertension who were hospitalized to receive treatment with endoscopic ligation. Sessions of ligation were repeated every two to three weeks until the varices were eradicated. The primary end point was recurrent bleeding. RESULTS: The median follow-up period was 32 months. A total of 126 patients had recurrent bleeding. All episodes were related to portal hypertension and 79 to recurrent variceal bleeding. There were major complications in 51 patients (30 had bleeding esophageal ulcers). Seventy-eight patients died, 26 deaths were related to variceal bleeding and 1 to bleeding esophageal ulcers. CONCLUSIONS: A great improvement in the prevention of variceal bleeding has emerged over the last years. However, further therapeutic options that combine higher efficacy, better tolerance and fewer side effects are needed.

BACKGROUND: Catastrophic antiphospholipid syndrome is a distinctly rare dramatic condition characterized by widespread thrombosis of small vessels. Early diagnosis and aggressive therapies are essential in this condition because of its extremely high mortality rate. Therapeutic management include heparine, high dose steroids, cyclophosphamide, plasma exchange, intravenous immunoglobuline, however a number of patients are refractory to treatment. AIM: We review and discuss alternative and emerging treatment options by rituximab for patients who fail or cannot tolerate conventional therapy. CASE-REPORT: A 36-year-old female with a two mounths history of dyspnea, palpitation and chest pain was admitted. Physical examination upon admission revealed a fever, ischemic digital necrosis, scleroderma of the hands and beaking of the nose. Laboratory tests showed normal level of liver enzymes, elevation of creatinine level, lymphopenia, haemolytic anaemia with negative Coombs tests, low platelet count, prolonged partial thromboplastin time. The D-Dimer value was 158 ng/ml. Urinalysis revealed a proteinuria. Antinuclear antibody tests and lupus anticoagulant were strongly positive. Echocardiography revealed severe pulmonary hypertension and pericarditis. There was no pulmonary embolism on thoracic angio tomodensitometry. The diagnosis of catastrophic antiphospholipid antibody syndrome associated with systemic lupus and scleroderma was established. She was treated with anticoagulants, corticotherapy, one pulse of intravenous cyclophosphamide, 2 doses of intravenous immunoglobuline and 5 sessions of plasmapheresis. Because of lack of response 2 doses of 375 mg weekly rituximab i.v. were added but she developed pulmonary embolism, alveolar haemorrhage and she died. CONCLUSION: Effectiveness of Rituximab for the CSAPL should be demonstrated by further studies.
