ERS recommends add-on sotatercept across three risk strata in PAH, and sugammadex edges neostigmine on postoperative pulmonary complications
The European Respiratory Society updates its pulmonary arterial hypertension guideline around sotatercept with high certainty of evidence; an indirect comparison finds nothing between mepolizumab and dupilumab in eosinophilic COPD; hypoxic burden identifies which sleep apnoea patients gain most from PAP adherence; and SNaPP puts numbers on a reversal-agent choice made thousands of times a day.
The edition in brief
An ERS Task Force has updated its pulmonary arterial hypertension treatment guideline using GRADE methodology. It recommends add-on sotatercept, an activin signalling inhibitor, for patients already on PAH drugs who are at intermediate-low, intermediate-high or high risk of death, based on high certainty of evidence; no recommendation is made for low-risk patients because the evidence is of low certainty and few such patients entered the trials. It also suggests right heart catheterisation during follow-up in the same three risk strata where therapeutic consequences are expected. A matching-adjusted indirect comparison of three mepolizumab trials against two dupilumab trials in COPD with an eosinophilic phenotype found no significant difference in annualised moderate or severe exacerbation rate (rate ratio 0.91, 95% CI 0.60-1.37 by investigator-assessed chronic bronchitis; 1.13, 0.80-1.58 by questionnaire definition) or quality of life. In 3,370 PAP-treated patients with moderate-to-severe obstructive sleep apnoea followed for a median nine years, adherence was associated with lower major adverse cardiovascular events (adjusted HR 0.53, 95% CI 0.46-0.62), with a stronger association in those with high hypoxic burden or heart-rate response (interaction HR 0.61, 0.43-0.87). The AZIMUNE trial of 40 adults with uncontrolled asthma found azithromycin raised rhinovirus-induced epithelial interferon-beta and interferon-lambda and lowered IL-33, without significant clinical differences. The edition closes on SNaPP, in which sugammadex reduced postoperative pulmonary complications or death from 21.5% to 19.0% across 3,498 patients.
ERS now recommends add-on sotatercept for PAH at intermediate-low risk and above
Sotatercept now belongs in routine escalation for PAH patients at intermediate-low risk or above who are already on therapy — in a specialist centre.
No detectable difference between mepolizumab and dupilumab in eosinophilic COPD
Pick between mepolizumab and dupilumab in eosinophilic COPD on practical grounds; the available evidence shows no efficacy difference to choose on.
Hypoxic burden identifies which sleep apnoea patients gain cardiovascular benefit from PAP adherence
Use hypoxic burden to decide where to spend effort on PAP adherence — the cardiovascular association was concentrated in high-burden patients, sleepy or not.
Azithromycin restored epithelial interferon responses in asthma — the mechanism behind an established effect
This explains why maintenance azithromycin reduces asthma exacerbations; it does not widen who should receive it.
Watch the patient use their own inhaler at every visit, not just the first
Before escalating therapy for uncontrolled asthma or COPD, watch the patient use their own inhaler — delivery failure looks exactly like treatment failure.
Sugammadex cut postoperative pulmonary complications from 21.5% to 19.0%
Sugammadex reduces postoperative pulmonary complications slightly, almost entirely through atelectasis — a real but small benefit to weigh against a large cost difference.
