Iv steroids for acute asthma

Short courses of systemic corticosteroids may provide important benefits in patients with exacerbations of COPD. A recent clinical trial 32 involving 271 patients in Veterans Affairs hospitals showed that steroid therapy resulted in moderate improvement of clinical outcomes, with shorter hospital stays and increases in FEV 1 . The fact that there were no significant differences between patients treated for two weeks and those treated for eight weeks justifies the use of a shorter course of corticosteroids to reduce the occurrence of adverse effects. Adverse effects can include hyperglycemia, secondary infection and behavioral changes. 33

Although the concurrent presence of the characteristic rash provides suggestive clinical evidence, biopsy is the most definitive method to diagnose GVHD of the liver. However, this may not be feasible because of the possibility of acute bleeding due to severe thrombocytopenia soon after HCT. A transjugular hepatic biopsy may be preferred if an adequate amount of tissue can be obtained. The primary histologic finding is extensive bile duct damage (eg, bile duct atypia and degeneration, epithelial cell dropout, lymphocytic infiltration of small bile ducts), leading to occasionally severe cholestasis [ 26,31-33 ].

Refractory acute graft-versus-host disease (aGVHD) remains an important cause of mortality after allogeneic stem cell transplantation. No standard therapy exists once steroids fail to obtain a good response. In 2006, our group published a series of patients who received inolimomab, an anti-interleukin-2 receptor monoclonal antibody, as salvage therapy with initial encouraging results. In this update, we analyzed a larger group of patients with prolonged follow-up. Ninety-two consecutive patients were treated with inolimomab at our center between April 1999 and December 2011. Overall response rate was 42% (complete response in 14%) on day +30. Predictors of failure to respond in the multivariate analysis were overall aGVHD grade IV, instauration of inolimomab before day 15 of aGVHD diagnosis, and severe lymphopenia. Patients without gastrointestinal involvement appeared to do better, with a 70% response rate compared with 39% in patients with gastrointestinal involvement (P = .06). However, the 2-year overall survival rate was of 18% for the entire cohort (95% confidence interval, 10% to 26%) and 33% for day 30 responders (95% confidence interval, 25% to 40%) and Acute GVHD was the main cause of death (49%) followed by opportunistic infections (27%). Results of this update show that although inolimomab is a well-tolerated drug with a moderate number of short-term responses, it is associated with long-term survival in only one-third of responding patients. These data highlight the need to investigate new rescue treatments with sustained effect and the importance of reporting long-term outcomes in GVHD studies.
