[Infectious endocarditis in patients with liver cirrhosis].

To evaluate the clinical and microbiological features of infective endocarditis in patients with cirrhosis we compared 18 episodes of endocarditis in these patients with a control group of patients without liver disease. In 61% of patients with cirrhosis the origin of infection was unknown. Four patients developed endocarditis as a consequence of bladder catheterizations and two after hepatic biopsy. None of the four with previously known valvular heart disease had received antibiotic prophylaxis during these procedures. As compared with the control group, the patients with cirrhosis had more infections by enterococci (38.8% vs 11%; p less than 0.007) and non-viridans streptococci (38.8% vs 7.4%; p less than 0.001) and significantly less infections by viridans streptococci (11% vs 42.5%; p less than 0.01). The mortality rate associated with endocarditis was 38.8% and 22% in patients with and without cirrhosis, respectively (less than 0.1; NS). Infective endocarditis in patients with cirrhosis is often a complication of diagnostic or therapeutic procedures and has distinctive microbiological features.

[Ki-1 non-Hodgkin's lymphoma. A multihospital study of 21 cases].

The Ki-1 monoclonal antibody recognizes a specific membrane antigen of activated lymphoid cells and stains large-cell non Hodgkin's lymphomas and Hodgkin's disease. Thus, it is widely used in the diagnosis of anaplastic lymphomas. Morphologically, the Ki-1 monoclonal non Hodgkin's lymphoma are diffuse of multifocal either classical or cell anaplastic type. The clinical behaviour is similar to the rest of the high grade lymphomas, disseminated at diagnosis but may reach remission after aggressive chemotherapy. The immunophenotype showed T, B or null nature of the latter. The clinical and pathological results of our study carried out in a group of 21 cases ki-1 positive lymphomas is herewith reported.

Malignant B cell immunoblastic lymphoma expressing CD30 antigen in the terminal phase of a multiple myeloma.

An acute terminal phase of a Bence Jones kappa plasma cell myeloma developed 22 months after chemotherapy is presented. The patient's symptoms were fever, cytopenias, adenomegalies and hepatomegaly. A lymph node biopsy showed an immunoblastic polymorphic kappa B cell lymphoma, expressing CD30 antigen. After new polychemotherapy the patient died because of bleeding and infection. Autopsy revealed a decrease in the tumour with defective immunophenotype. The few reported cases have been reviewed with emphasis on clinical aspects, prognosis and morphology, The significance of CD30 positivity (activation marker) in a high-grade lymphoma is discussed.
