Systemic lupus erythematosus (SLE) is considered the archetypal systemic autoimmune disease. Clinically characterized by multisystem involvement and varied serologic abnormalities, no two patients present or have disease that evolves in exactly the same way. Viewed histologically, SLE is characterized by some combination of inflammation and fibrosis, and the clinical phenotype is dictated by the relative contributions of each and the organs affected. ⋯ As expected in a multisystem disease, the entire pulmonary system is vulnerable to injury. Any of its compartments-airways, lung parenchyma, vasculature, pleura, or the respiratory musculature-may be independently or simultaneously affected. This article offers the reader a comprehensive review of the numerous pulmonary and thrombotic manifestations of SLE and suggests approaches to their management.

Fluid infusion may be lifesaving in patients with severe sepsis, especially in the earliest phases of treatment. Following initial resuscitation, however, fluid boluses often fail to augment perfusion and may be harmful. In this review, we seek to compare and contrast the impact of fluids in early and later sepsis; show that much fluid therapy is clinically ineffective in patients with severe sepsis; explore the detrimental aspects of excessive volume infusion; examine how clinicians assess the intravascular volume state; appraise the potential for dynamic indexes to predict fluid responsiveness; and recommend a clinical approach.
