流感重症，不要用類固醇
severe H1N1 infection, 今年冬季大家領教過了吧……
歐洲的觀察，用steroid trying to decrease cytokine storm是無益的
會增加肺炎機會
個人見解：
這次流感的ARDS
60-70歲以上的病人，除非underlying太差，雖敗不亂，用呼吸器可以徐圖漸進，日日有起色，眼睛烏亮亮，不會讓你想用類固醇
30-40歲的人，一來就撐不住，馬上轉到敏盛/長庚用ECMO，用啥都沒用
either case -> 都用不到 steroid
Severe H1N1 Influenza Infection: Hold the Corticosteroids!
An observational European study shows that corticosteroids increased risk for pneumonia and conferred no mortality benefit in patients with severe H1N1 infection.
Use of corticosteroids to mitigate the cytokine storm that might contribute to poor outcomes in otherwise healthy people with pandemic H1N1 influenza infection is controversial, even in those with acute respiratory distress syndrome (ARDS). In a prospective observational study, investigators evaluated the effect of corticosteroids on outcomes in 220 intensive care unit (ICU) patients who were enrolled in the European Society of Intensive Care Medicine H1N1 registry from June 2009 through February 2010. H1N1 influenza A infection was confirmed in 194 patients, probable in 2, and suspected in 24. All patients received antivirals, and 78% were mechanically ventilated.
The 126 patients (57%) who received corticosteroids on ICU admission (dosages equivalent to >24 mg/day of methylprednisone or >30 mg/day of prednisone), compared to patients who did not, were significantly older, more likely to have comorbid pulmonary conditions, and more likely to be chronic corticosteroid users. Although patients who received corticosteroids on ICU admission were significantly more likely to contract hospital-acquired pneumonia (26% vs. 14%; odds ratio, 2.2) and to die in the ICU (46% vs. 18%; OR, 3.8), the association with mortality was no longer present after adjustment for severity of disease and other confounding variables (age, asthma, chronic obstructive pulmonary disease, chronic corticosteroid use). Results were similar when the analysis was limited to the 74% of patients with ARDS.
Comment: This study is limited by its observational nature, variable dosing of oseltamivir, and that patients who received "rescue" corticosteroids after ICU admission were not considered part of the corticosteroid group. For now, corticosteroids do not seem helpful — and might be harmful — in patients with H1N1 influenza.
