Bitter et al performed CPAP titration on 192 patients with congestive heart failure and obstructive sleep apnea, unmasking residual central sleep apnea (so-called complex sleep apnea) in 34 (18%). Providing adaptive servoventilation (dynamic delivery of pressure support to achieve a target minute ventilation) improved AHI, NYHA class, BNP levels, ejection fraction, and other variables, at ~1 year [… read more]

Parra et al diagnosed OSA in 140 patients hospitalized for stroke in Spain and randomized them to nasal auto-titrating CPAP or no therapy. The CPAP-treated patients had better Rankin and Canadian stroke outcome scores at all follow-up visits. They had the same rate of subsequent cardiovascular events, but events occurred at a median 15 months [… read more]

Patients taking pramipexole for 6 months had a 14-point fall in their IRLS score, and 59% “responded” (had at least a 50% fall in their score). But time worked well, too: placebo patients had an 11-point decline in scores and 43% responded. So 1 in 6 responded to pramipexole, practically speaking (they don’t say this, [… read more]

Fen-phen died in court, but phenteramine was cleared of all serious charges. Gadde et al report phase III results for Qnexa (by Vivus), a phenteramine-topiramate combination. Over 56 weeks, takers of a double-dose of study drug lost 10 kg; single-dose, 8 kg; and placebo, 1.4 kg. There were plenty of side effects (dry mouth and paresthesias [… read more]

Gooneratne et al selected 289 people over 65 (nondemented, nondepressed), half of whom had excessive daytime sleepiness (EDS). All got polysomnograms and were followed for a mean of 14 years. Those with EDS and sleep disordered breathing (SDB) had a hazard ratio for mortality of 2.7, that fell to 2.3 after adjusting for covariates. People [… read more]

Lettieri et al prospectively observed 210 patients with obstructive sleep apnea, who were diagnosed & titrated in-lab or at home. Those who were diagnosed and titrated at home and managed through their primary care clinic had equivalent adherence with CPAP therapy (~70% of nights; ~4.5 hrs/night; regular use ~52%) to those diagnosed and titrated in-lab [… read more]

Chai-Coetzer et al designed and validated a predictive model for diagnosing obstructive sleep apnea without polysomnography in 157 general primary care patients considered at average risk for obstructive sleep apnea. Berlin/Epworth questionnaires, snoring, waist size, witnessed apneas and age were fit into an algorithm, followed by home oximetry in a sample of mostly high-Berlin-scoring patients. [… read more]

Priou et al followed 130 patients with OHS after initiation with noninvasive positive pressure ventilation. Mean follow up was 4 years. Most (96) were started on NPPV in the stable state; 38 had had an acute hypercapneic exacerbation. Survival at 1 year was 97.5%; 2 years (93%); 3 years (88%); 5 years (77%). The large [… read more]
