GESIDA/PETHEMA recommendations on the diagnosis and treatment of lymphomas in patients infected by the human immunodeficiency virus. / Recomendaciones de GESIDA/PETHEMA sobre el diagnóstico y tratamiento de los linfomas en pacientes infectados por el virus de la inmunodeficiencia humana.

The incidence of non-Hodgkin's lymphoma and Hodgkin's lymphoma is higher in patients with HIV infection than in the general population. Following the introduction of combination antiretroviral therapy (cART), the prognostic significance of HIV-related variables has decreased, and lymphoma-related factors have become more pronounced. Currently, treatments for lymphomas in HIV-infected patients do not differ from those used in the general population. However, differentiating characteristics of seropositive patients, such as the need for cART and specific prophylaxis and treatment of certain opportunistic infections, should be considered. This document updates recommendations on the diagnosis and treatment of lymphomas in HIV infected patients published by GESIDA/PETHEMA in 2008.

[Study of effectiveness of 3 schedules of administration of erythropoietic colony-stimulating factors in anemic patients under chemotherapy for solid or hematology malignancy]. / Estudio de la efectividad de tres esquemas de administración de factores estimuladores de la eritropoyesis en pacientes con anemia asociada a quimioterapia por una neoplasia sólida o hematológica.

BACKGROUND AND OBJECTIVE: The treatment of chemotherapy associated anemia in patients with cancer has varied greatly in recent years. The objective of this study was to verify whether the most frequently used therapeutic schedules of erythropoietin administration demonstrate equivalent effectiveness. PATIENTS AND METHOD: Treatments corresponding to 1,103 patients with cancer receiving treatment with erythropoietic colony-stimulating factors from January 2003 to April 2006 were reviewed. After applying a selection algorithm, 170 cases were analysed: 55 treated with epoetin alpha 10,000 IU 3 times per week, 63 receiving darbepoetin alpha 150 microg weekly and 52 treated with darbepoetin alpha 500 microg every 3 weeks. The main variables used to compare effectiveness were the increase in serum hemoglobin levels during treatment and the percentage of patients with hemoglobin values > or = 120 g/l. RESULTS: The differences in maximum hemoglobin values achieved at baseline and during the study period, and those between the final and baseline hemoglobin values were similar in the 3 groups. The percentage of patients with hemoglobin values > or = 120 g/l during and at the end of treatment was equivalent for the group receiving epoetin alpha 10,000 IU three times per week and darbepoetin alpha 150 microg per week. However this parameter war inferior for the group treated with darbepoetin alpha 500 microg every 3 weeks. CONCLUSIONS: Epoetin alpha 10,000 IU 3 times per week was found to be as effective as darbepoetin alpha 150 microg per week in all the studied parameters, while darbepoetin alpha 500 microg every 3 weeks was not in one of them.
