Use of corticosteroids in acute respiratory distress syndrome: Perspective from an Indian intensive care unit
Journal Title: Medical Journal Armed Forces - Year 2017, Vol 73, Issue 2
Abstract
Background: Acute respiratory distress syndrome (ARDS) causes overwhelming inflammation, which serves as a potential target for corticosteroids. Despite extensive Western literature, there are no Indian studies evaluating steroids in ARDS. Methods: This was a retrospective study at an Indian intensive care unit (ICU) on ARDS patients. Demographic, clinical, laboratory, and imaging parameters were collected. Patients were divided into cohorts based on steroid use, and some received high-dose (2 mg/kg/day), whereas others received low-dose (1 mg/kg/day) steroids. Primary outcomes were in-hospital mortality and secondary outcomes included need for and duration of invasive mechanical ventilation (IMV), IMV-free days, ICU length of stay (LOS), and total LOS. Two-tailed p < 0.05 was considered statistically significant. Results: During the 20-month period, 95 patients [median age 37 (30–47) years; 48 (50.5%) males] met our inclusion criteria. Steroid use was noted in 48 (50.5%) patients [11 (22.9%) low-dose and 37 (77.1%) high-dose]. Baseline characteristics of the cohorts, including ARDS severity indices, were comparable. Of these 95 patients, 70 (73.7%) had sepsis, but microbiological diagnosis was positive only in 17 (17.9%) patients. Steroid use did not significantly influence mortality [odds ratio (OR) 0.6 (0.3–1.4)] or need for IMV [OR 1.0 (0.4–2.6)]. There were no differences in outcomes of IMV-free days, ICU LOS, or total LOS. These outcomes were comparable between the high-dose and low-dose steroid users. Conclusions: Steroid use and comparison of low-dose vs. high-dose steroids did not influence outcomes associated with ARDS in the Indian population.
