LUPUS ANTICOAGULANT HYPOPROTHROMBINEMIA SYNDROME: A CASE REPORT

Lupus anticoagulant hypoprothrombinemia síndrome (LAHPS) is a rare entity. A 54-year-old woman diagnosed with systemic lupus erythematosus (SLE) present in August 2020 with cerebellar haemorrhage, coagulation factor II deficiency was found. After increasing corticosteroid dose and adjustment of immunosuppressive therapy FII levels increased. She has no presented new haemorrhagic events.

P258 Real-world secukinumab retention, response rates and adverse events in the treatment of PsA and axSpA

Background Secukinumab, an IL-17A inhibitor, has been licensed for use in the United Kingdom for both axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) for several years. Despite this there is minimal published data on its use out with randomised controlled trials. We present here the collated real-world rheumatology experience of secukinumab use in Glasgow. Methods Patients who have ever received secukinumab for any rheumatology indication were identified using available medical records (from 14/05/2012 to 18/09/2019). Diagnosis, baseline demographics, disease activity at baseline and at 6 months, and whether patients are still currently on secukinumab was recorded. Primary inefficacy was defined as stopping treatment due to inefficacy ≤6 months. Reasons for discontinuation were also recorded. As disease activity scores were variably recorded, the primary outcome was retention rate as a surrogate for efficacy and lack of adverse event. Patients only included in disease scores if scores available both at baseline and 6 months. Results 352 patients (with 530 patient-years of exposure) identified. 251 (71.3%) patients currently remain on secukinumab. 301 of 336 (89.6%) patients remained on drug at six-month review (16 await review). Characteristics and response of two main diagnostic groups listed in Table 1 (Note: 3 patients had SAPHO, 5 had Juvenile Idiopathic Arthritis, 1 had reactive arthritis). Common adverse events were infections (11 patients), rash and/or pruritis (6 patients), mood change and/or fatigue (4 patients). Three patients developed inflammatory bowel disease (IBD) subsequent to starting secukinumab. Five patients had pre-existing IBD, none of which flared on secukinumab. Two patients required hospitalisation for abscesses whilst on secukinumab. One patient had a stroke and one patient had a myocardial infarction whilst on secukinumab - both patients had multiple risk factors for cardiovascular disease. No malignancies identified. Three patients died, with none felt related to secukinumab (cerebellar haemorrhage in warfarinised patient with high INR; pneumonia six months after switching from secukinumab to tocilizumab; one out of hospital death over one year after stopping secukinumab). Conclusion In this real world cohort of patients with axSpA and PsA, secukinumab retention rates at 6 months are high with no new safety signals identified. Disclosures A. Tindell None. S.

Cerebellar Haemorrhage Leading to Sudden Cardiac Arrest

IntroductionIntracranial haemorrhage (ICH) is a known, but a rare cause of out of hospital cardiac arrest (OHCA). It results in the development of non-shockable rhythms such as asystole or pulseless electrical activity (PEA).Case ReportA 77- years old male had an OHCA without any prodrome. An emergency medical services (EMS) team responded to an emergency call and intubated the patient at the site before transporting him to the Acute Care Hospital, New Brunswick, New Jersey, USA. On admission, a non-contrast computed tomography scan of the head revealed a large cerebellar haemorrhage. Non-traumatic ICH is a rare cause of OHCA. Although subarachnoid haemorrhage causing cardiac arrest has been described in the literature, cerebellar haemorrhage leading to cardiac arrest is rare. The mechanism by which ICH patients develop cardiac arrest is likely explained by a massive catecholamine surge leading to cardiac stunning.ConclusionA non-shockable rhythm in the seting of a sudden cardiac arrest should raise alarms for a primary non-cardiac ethology, especially a primary cerebrovascular event. The absence of brainstem reflexes increases the likelihood of an intracranial process.

P684 The effect of tofacitinib on serum lipids and cardiovascular safety in patients with ulcerative colitis: updated results from the tofacitinib ulcerative colitis clinical programme

Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). In the tofacitinib UC clinical programme, the majority of patients did not have cardiovascular (CV) risk factors at baseline (BL), and increases in lipid levels occurred primarily during induction and remained elevated to Week 61 during maintenance; lipid ratios were relatively unchanged.1 Here, we present updated results of lipid levels in the ongoing, open-label, long-term extension (OLE) study (NCT01470612) and major adverse CV events (MACE) in the Phase 3/OLE tofacitinib UC clinical programme. Methods Lipid levels were assessed at multiple time points, and changes from OLE study BL to Month 48 in the OLE study were evaluated. Lipid-lowering agent (LLA) use (proportion of patients) and adjudicated MACE (proportion of patients and incidence rate [IR; unique patients with events per 100 patient-years] with 95% confidence interval [CI]) were reported in patients with UC in two Phase 3, 8-week, placebo-controlled induction studies (OCTAVE Induction 1 and 2; NCT01465763, NCT01458951), a Phase 3, 52-week, placebo-controlled maintenance study (OCTAVE Sustain; NCT01458574) and the OLE study (data as of May 2019; database not locked). Results No major changes in total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), triglycerides, LDL-c:HDL-c and TC:HDL-c from OLE study BL were observed at Month 48 of the OLE study (Table). In the Phase 3/OLE programme (n = 1124), 7.7% of patients had a new LLA added and 1.9% of patients had their LLA dose increased. Seven MACE were reported (IR 0.26; 95% CI 0.11, 0.54; 2654.66 patient-years); the IR has remained stable since Dec 2016 (IR 0.24; 95% CI 0.07, 0.62).1 Reported MACE was one each of myocardial infarction, acute myocardial infarction, acute coronary syndrome, cerebrovascular accident, haemorrhagic stroke, cerebellar haemorrhage and aortic dissection. Both myocardial infarction events and the acute coronary syndrome event led to temporary tofacitinib discontinuation; the haemorrhagic stroke, cerebrovascular accident and cerebellar haemorrhage led to permanent tofacitinib discontinuation; and the aortic dissection resulted in death. Of the seven patients with MACE, five had CV risk factors at BL. Conclusion At Month 48 of the OLE study, lipid levels and ratios remained generally unchanged from OLE study BL following tofacitinib treatment. MACE were infrequent, with the IR remaining stable since the previous report.1 Limitations include low patient numbers and short tofacitinib exposure duration. Longer-term observation studies will further assess risk. Reference

Neuroimaging findings in newborns with congenital heart disease prior to surgery: an observational study

ObjectivesNeurodevelopmental impairment has become the most important comorbidity in infants with congenital heart disease (CHD). We aimed to (1) investigate the burden of brain lesions in infants with CHD prior to surgery and (2) explore clinical factors associated with injury.Study designProspective observational study.SettingSingle centre UK tertiary neonatal intensive care unit.Patients70 newborn infants with critical or serious CHD underwent brain MRI prior to surgery.Main outcome measuresPrevalence of cerebral injury including arterial ischaemic strokes (AIS), white matter injury (WMI) and intracranial haemorrhage.ResultsBrain lesions were observed in 39% of subjects (95% CI 28% to 50%). WMI was identified in 33% (95% CI 23% to 45%), subdural haemorrhage without mass effect in 33% (95% CI 23% to 45%), cerebellar haemorrhage in 9% (95% CI 4% to 18%) and AIS in 4% (95% CI 1.5% to 12%). WMI was distributed widely throughout the brain, particularly involving the frontal white matter, optic radiations and corona radiata. WMI exhibited restricted diffusion in 48% of cases. AIS was only observed in infants with transposition of the great arteries (TGA) who had previously undergone balloon atrial septostomy (BAS). AIS was identified in 23% (95% CI 8% to 50%) of infants with TGA who underwent BAS, compared with 0% (95% CI 0% to 20%) who did not.ConclusionsCerebral injury in newborns with CHD prior to surgery is common.

Remote Cerebellar Haemorrhage: A Potential Iatrogenic Complication of Spinal Surgery

We report the case of a 51-year-old man with no significant past medical history, who underwent elective revision spinal surgery and subsequently developed intracranial hypotension, remote cerebellar haemorrhage (RCH), and mild hydrocephalus on the fourth postoperative day. Remote cerebellar haemorrhage is a known complication of supratentorial surgery. This iatrogenic phenomenon may also occur following spinal surgery, due to dural tearing and rapid cerebral spinal fluid (CSF) leakage, resulting in intracranial hypotension and cerebellar haemorrhage. This complication may result in severe permanent neurologic sequelae; hence, it is of pertinence to diagnose and manage it rapidly in order to optimise patient outcome.

Remote Cerebellar Haemorrhage after Surgery for Craniopharyngioma: a case report

Postoperative remote cerebellar haemorrhage occurring distant to the operated site as its name suggests is a rare though recognized entity in neurosurgical practice. It can be potentially devastating. Over 100 cases have been described in various literatures over the years. It is postulated to be due to CSF over drainage, has been the most popular theory behind its occurrence. We report a patient who underwent pterional craniotomy for craniopharyngioma, who deteriorated 12 hours following awakening after the surgery, the cause being remote cerebellar haemorrhage.Nepal Journal of Neuroscience, Volume 15, Number 2, 2018, Page: 45-48
