Hooman et al pooled 5 randomized trials with 112 patients, who had 184 episodes of elevated intracranial pressure. They concluded hypertonic saline is better at reducing ICP; but the relative-risk-for-ICP-control confidence interval was 1.0-1.3 and the mean ICP reduction included zero (-1.6 to 5.7 mm Hg). So, maybe. Crit Care Med 2011;39:554-559.
Busse et al randomized 419 inner-city kids (age 6-20) with uncontrolled, skin-test-positive, mostly severe allergic asthma and IgE < 1,300 IU/mL to 60 weeks of omalizumab or placebo. The treated group had modest improvements: ~1 fewer day of symptoms per month and a 5% absolute reduction in hospitalizations (1.5% vs 6.3%); 18% fewer of them [… read more]
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.

Accurso et al report phase 3 results from industry-funded TIGER-1, testing t.i.d. inhaled denufusol (an ion channel regulator that alters sodium/chloride transport to improve mucociliary clearance) vs. placebo in early cystic fibrosis (FEV1>74% predicted). After 24 weeks, FEV1 was 45 mL better in the treated group, most of whom were younger than age 19. There [… read more]
Valdyanathan et al gave prednisolone 25 mg (equivalent to prednisone) or placebo daily for 2 weeks to sufferers of chronic rhinosinusitis in the UK, followed by 8 months of nasal fluticasone (drops, then spray) for all. The orally-treated group had a 2.1-point fall in their polyp grade and could smell better, at 6 months. Ann [… read more]
How “hard” should we “hit” our patients with Lasix? And does that hurt? Felker et al asked that (sort of) in a NHLBI-funded trial. They gave furosemide to 308 patients hospitalized for ADHF in an IV dose either equivalent to their home dose, or at 2.5 times their home dose, and either at q12-hour intervals [… read more]
In a rare encouraging positive study in the chronically critically ill, 71% of vent-dependent patients (~6 weeks on MV) who did multiple sets of daily inspirations backwards through a PEEP valve weaned from mechanical ventilation (defined as >72 hrs off the vent), vs. 47% receiving a sham treatment. MIP also improved by 10 cmH2O in [… read more]
Tashkin et al randomized 504 patients at 27 centers with COPD and FEV1 > 49% to varenicline or placebo for 12 weeks, with 52 weeks follow up. Smoking cessation / abstinence rate (carbon monoxide-confirmed) was 42% vs 9% in weeks 9 – 12 (1′ endpoint), and 19% vs. 6% in weeks 9 – 52 (p<0.0001). [… read more]
The once-daily beta-agonist was better than placebo and at least as good as twice-daily salmeterol, as measured by the SGRQ, TDI, and FEV1 after 12 weeks. The drug previously matched up well against tiotropium. Indacaterol is available in Europe, but not in the U.S. (n=838). ERJ 2011;37:273-279.
McCormack et al randomized 89 women with lymphangioleiomyomatosis to receive 2 mg rapamycin or placebo daily for 12 months, followed by 12 months of drug-free observation. Women receiving sirolimus had stable lung function on spirometry, fewer symptoms, fewer “respiratory events,” and better quality of life during the treatment period. This was tempered by GI, dermatologic, [… read more]
Daily inhaled corticosteroids (ICS) may retard growth in children, who would rather play than take daily inhalers. Martinez et al randomized children with mild persistent asthma to four groups, one of which was beclomethasone + albuterol as rescue therapy only (i.e., no daily ICS), for 44 months. They did slightly worse than children taking daily [… read more]
Ciclesonide, a new inhaled corticosteroid that seems to cause thrush less often than others, reached for equivalency with salmeterol/fluticasone in mild persistent asthma. Ciclesonide was better than placebo in controlling asthma but Advair users had a longer time to first asthma exacerbation. CHEST 2011;139: online supplement. A Cochrane review on ciclesonide could not establish its [… read more]
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.
Patients with on-site evaluation of TBNA samples had fewer sites sampled (1 vs. 2) and general complications (6% vs. 20%), with an equivalent yield compared to patients undergoing usual TBNA (n=168). CHEST 2011;139:395-401.
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]
