[Hemophagocytic lymphohistiocytosis. Experience in 27 patients].

Background: Hemophagocytic lymphohistiocytosis (HLH) is an aggressive and life-threatening syndrome of excessive immune activation Aim: To describe the clinical characteristics, causes and survival associated with HLH.

Material And Methods: Review of medical records of patients with HLH attended between 2004 and 2016. They were classified according to their probable cause in: associated with immunosuppression, cancer, post-infectious or idiopathic.

Effect of angiotensin 2 receptor blockers on chronic obstructive lung disease mortality: A retrospective cohort study.

Introduction: Chronic Obstructive Pulmonary Disease (COPD) is the fifth cause of mortality worldwide. Systemic inflammation is a crucial element in its physiopathology. As Renin-Angiotensin System is one of the main components of this inflammatory neurohumoral cascade, Angiotensin Receptor Blockers (ARBs) might have an effect on mortality in COPD patients.
