After analyzing all AstraZeneca’s clinical trials data on budesonide for asthma (26 placebo-controlled, n~14,000; 60 non-placebo-controlled, n~33,000), O’Byrne et al found no increased risk of pneumonia with use of budesonide by asthmatics, who contracted 1-2 detected pneumonias per 100 patient-years of treatment. AJRCCM 2011;183:589-595.
Roquilly et ses amis francais randomized 150 critically ill victims of severe French trauma to hydrocortisone or placebo for 7 days. The treated group had an absolute 16-19% lower risk for hospital-acquired pneumonia, the primary endpoint (36% vs. 51-54% depending on which intention-to-treat analysis you prefer, p=0.007 to 0.01). (n=150). JAMA 2011;305:1201-1209.
Fernandez-Cerrano et al randomized 56 people with CAP in Spain (only 3 needed mechanical ventilation) to receive methylprednisolone bolus-and-taper or placebo, in addition to ceftriaxone and levofloxacin. The steroid-treated group had less hypoxemia (lower PaO2/FiO2). (n=56). Critical Care 2011;15:R96.

In a very small trial (n=24), inhaled RNA (ALN-RSV01) appeared to improve outcomes in lung transplant patients with RSV respiratory infections, by interfering with viral replication. Symptoms were reduced, and at 90 days, incidence of bronchiolitis obliterans syndrome was 6% vs 50% in the control group. AJRCCM 2011;183:531-538.
12 months of nebulized gentamicin (80 mg bid) markedly reduced symptoms, exacerbations, and bacterial density in people with bronchiectasis from causes other than cystic fibrosis. None of these benefits were sustained after 3 months without therapy, though. (n=65). AJRCCM 2011;183:491-499.
Louie et al report results of a phase 3 industry-funded trial of fidaxomicin, a poorly absorbed oral macrolide that’s bacteriocidal vs C. difficile. The new drug was equivalent to oral vanco in curing C.diff infections (~90%), and superior at preventing recurrences (~14% vs 24%). It did not prevent recurrences of the more lethal and increasingly [… read more]
