RESUMO
INTRODUCTION: Iron deficiency anemia (IDA) has a prevalence of 20-24.5% in Mexico, which is similar to other developing countries. Although the treatment of choice is oral iron therapy, several factors limit its efficacy. Intravenous administration of iron-dextran is an effective method that has been evaluated in pregnant women, children and renal patients and there are some studies demonstrating its safety in these groups. We carried out a prospective, longitudinal, uncontrolled clinical trial to evaluate the safety and efficacy of total-dose intravenous iron infusion in the treatment of IDA in adult, non-pregnant patients. MATERIALS AND METHODS: Forty-seven patients (8 male, 39 female) with anemia and iron deficiency were included in the study. Iron deficit was calculated and a total dose iron infusion was administered intravenously diluted in normal saline over 4 hours. CBC were obtained at 2-week intervals until week 8 post-infusion. The percentage of hematocrit correction was calculated at week 8 post-infusion. RESULTS: Baseline hemoglobin values were 78 +/- 17.2 for the whole group, 85 +/- 20.4 for men and 78 +/- 16.7 g/L for women. At week 8 values were 134 +/- 10.7, 138 +/- 9.8 and 134 +/- 10.8 g/L for the whole group, men and women, respectively. Baseline hematocrit values were 0.27 +/- 0.05 for the whole group, 0.29 +/- 0.06 for men and 0.27 +/- 0.05 for women. At week 8 values were 0.42 +/- 0.03, 0.43 +/- 0.03 and 0.42 +/- 0.03 for the whole group, men and women, respectively. The percentage of hematocrit correction was 51.5 +/- 28.6 at week 2 and 80.3 +/- 21.3 at week 8. Thirty-two percent of patients developed adverse reactions, all but one being mild. CONCLUSIONS: We confirmed that total-dose iron infusion is a safe and effective method to treat IDA that may be used in patients with intolerance to oral iron or in patients with failure to other iron schedules, as well as initial therapy in selected cases. Besides it provides a swift correction of hematocrit allowing, in some cases, to perform elective surgery without the need of blood transfusion.

Describimos nuestra experiencia en el estudio protocolizado de donadores sanos del programa de trasplante alogénico de médula ósea del Instituto Nacional de Cancerología de México. Se estudiaron 22 donadores sanos y 23 procedimientos de colección de médula ósea. Fueron 7 hombres y 15 mujeres, con edades de 16 a 47 años. Todos ellos fueron negativos a VIH, HB y HC. Se colectaron volúmenes de médula ósea de 750 a 1500 mL. Catorce donadores presentaron reducción de hemoglobina > 3.0 g/dL pero sólo la mitad de ellos requirieron transfuusión autóloga. Todos recibieron un programa de analgésicos con meperidina, dextropropoxifeno y ketoprofeno. Sólo dos donadores presentaron complicaciones (9 por ciento). Actualmente todos se encuentran en buenas condiciones de salud. Concluímos que la donación de médula ósea mostró ser un procedimiento seguro, con la complicación más frecuente de reducción de hemoglobina circulante que es fácilmente corregible con transfusión de sangre autóloga

Se informa la primera experiencia mexicana con el uso de factor estimulante de colonia granulocito-macrófago (GM-CSF) com profilaxis de la neutropenia secundaria a ganciclovir, en la prevención de la enfermedad por citomegalovirus (CMV) en un paciente CMV sero-positivo con leucemia mieloide aguda en primera remisión, trasplantando con donador HLA idéntico y CMV sero-positivo. La toma de injerto ocurrió el día 14. Se inició ganciclovir 5 mg/kg/3 veces por semana) en el día 35 acompañandose de toxicidad medular secundaria 28 días después con neutropenia grave que remitió de manera espontánea posterior a la suspensión del mismo. A fin de concluir el esquema de profilaxis, se inició GM-CSF a dosis de 300 mg/kg/día concomitante al ganciclovir a dosis de 5 mg/kg/día con lo cual fue posible conluir tratamiento sin que se reindujera toxicidad medular. No hubo evidencia de enfermedad de injerto contra huésped ni de infección por CMV. La evolución del paciente fue satisfactoria durante un año, posterior al cual, presentó recaída de su enfermedad de base mueriendo por complicaciones secundarias a leucemia
