Intensive blood pressure lowering after intracerebral haemorrhage cut recurrent stroke by about a third
Individual data from four trials show the benefit comes mainly from fewer repeat bleeds, within about six months. Also: new AAN/AHS migraine prevention guidance, antiseizure drug choice with DOACs, tirofiban in branch atheromatous disease and a weekly complement inhibitor for myasthenia.
The edition in brief
RECAP-ICH pooled individual data from four randomised trials of 2944 patients with previous spontaneous intracerebral haemorrhage, three-quarters of them Asian. An 11 mm Hg lower systolic pressure reduced first recurrent stroke from 10.4% to 6.5% (HR 0.62), mostly through fewer recurrent haemorrhages (HR 0.39), with no excess serious adverse events; a 1% absolute benefit accrued in about six months. The AAN and American Headache Society have published updated recommendations on preventive drugs for migraine in adults, covering when and what to start, specific populations and stopping. A target-trial emulation of 9529 adults with epilepsy on DOACs associated levetiracetam and strong enzyme inducers with more thromboembolic events than lamotrigine or lacosamide, and valproate with more intracranial bleeding. STRATEGY found tirofiban added to aspirin did not reduce early deterioration or new stroke in branch atheromatous disease (HR 0.88). PREVAIL found weekly self-injected gefurulimab improved MG-ADL by 1.6 points more than placebo in AChR-antibody-positive generalised myasthenia. Today's pearl: in a patient with epilepsy starting a DOAC, check the antiseizure drug for interactions before the first dose.
AAN and American Headache Society update migraine prevention guidance
Read the updated AAN/AHS migraine prevention guideline and match the choice of preventive to each patient's comorbidities and plans for pregnancy.
Antiseizure drug choice linked to thrombosis and bleeding in patients on DOACs
In patients with epilepsy on a DOAC, avoid strong enzyme-inducing antiseizure drugs and prefer lamotrigine or lacosamide where suitable.
Tirofiban with aspirin did not prevent deterioration in branch atheromatous disease stroke
Do not add tirofiban routinely for branch atheromatous disease stroke; it did not reduce early deterioration or new stroke.
Weekly self-injected gefurulimab improved generalised myasthenia gravis
Gefurulimab offers a self-injected complement option for antibody-positive generalised myasthenia, but regulatory status and access are not yet established.
Check the antiseizure drug before the first DOAC dose
Before starting a DOAC in a patient with epilepsy, check for enzyme-inducing antiseizure drugs and agree a plan with the neurologist.
Intensive blood pressure lowering after intracerebral haemorrhage prevents recurrent stroke
After spontaneous intracerebral haemorrhage, start and sustain intensive blood pressure lowering for every patient; it cuts recurrent stroke by about a third.
