          Abstract

          Introducción: La Eritrocitosis Secundaria (ES) está caracterizada por eritropoyetina sérica elevada y complicaciones como eventos trombóticos, Hipertensión Arterial Sistémica e Hipertensión Arterial Pulmonar. Su etiología está relacionada con EPOC u obesidad y es la eritrocitosis más frecuente (90%) en la altura. El tratamiento farmacológico base conlleva atorvastatina y aspirina. Objetivo: describir los resultados del tratamiento con atorvastatina y aspirina en eritrocitosis secundarias asociadas a EPOC u obesidad. Material y método: Estudio prospectivo longitudinal que incluyó 101 pacientes con ES (ES asociada a EPOC=25, ES asociada a obesidad=76), residentes en ciudades de La Paz (3650 msnm) y El Alto (4000 msnm). Se realizó estudios clínicos y laboratoriales. El tratamiento contempló dos fases; la primera, constituida por flebotomías; la segunda, por tratamiento con 20 mg de Atorvastatina VO/día y 100 mg de ASA VO día. Tras dos años de seguimiento de pacientes, se evaluó la respuesta al tratamiento. Resultados: El tratamiento alcanzó un 80 % de respuesta favorable en pacientes con ES a EPOC (Remisión Completa 44 % y Parcial 36 %) y un 53% en pacientes con ES a Obesidad (Remisión Completa 30 % y Parcial 23 %) reflejando mayor beneficio en aquellos con grados de obesidad moderada (53%) y severa (60%). Conclusión: El tratamiento con atorvastatina y aspirina beneficia más a pacientes con ES a EPOC que a pacientes con ES a Obesidad. Se requiere mejorar los resultados del tratamiento considerando la inclusión de otros fármacos y medidas para bajar de peso.

          Introduction: Secondary Erythrocytosis (SE) is characterized by increased serum erythropoietin and complications such as thrombotic events, Systemic Arterial Hypertension and Pulmonary Arterial Hypertension. Its etiology is related to COPD or obesity and represents the most frequent erythrocytosis (90%) at high altitude. The basis pharmacological treatment entails atorvastatin and aspirin. Objective: to describe the results of administrating atorvastatin and aspirin for treating secondary erythrocytosis associated with COPD or obesity. Material and method: Longitudinal prospective study that included 101 patients with SE (SE associated with COPD = 25, SE associated with obesity = 76) residing at high altitude (La Paz 3650 m, El Alto 4000 m). Clinical and laboratory studies were carried out. The treatment involved two phases: therapeutic phlebotomies and then treatment with 20 mg of Atorvastatin daily by mouth and 100 mg of ASA daily by mouth. The response to treatment was evaluated after 2-years follow-up. Results: The treatment achieved a favorable response 80% in patients with SE associated to COPD (Complete Remission 44%, Partial Remission 36%), and 53% in patients with SE associated to Obesity (Complete Remission 30%, Partial Remission 23%) as well as a higher benefit in those with Class I (53%) and Class II obesity (60%). Conclusion: Treatment with atorvastatin and aspirin is more beneficial in patients with SE to COPD than patients with SE to Obesity. The inclusion of other drugs and weight loss measures is necessary to improve treatment results.

          Effects of metformin on weight loss: potential mechanisms.

          Despite the known glucose-lowering effects of metformin, more recent clinical interest lies in its potential as a weight loss drug. Herein, we discuss the potential mechanisms by which metformin decreases appetite and opposes unfavorable fat storage in peripheral tissues.
