Long-term (>10-year) clinical follow-up after young embolic stroke/TIA of undetermined source

Background To date, the pathophysiology of first-ever and recurrent stroke/TIA still remains unclear in young patients with embolic stroke/TIA of undetermined source (ESUS). Clinical studies with long-term follow-up in young ESUS patients are necessary to investigate the underlying pathophysiology of first-ever and recurrent stroke/TIA in this patient population, in particular the role of new-onset atrial fibrillation. Aims Our aim was to study the long-term (>10-year) clinical outcome of young patients (<50 years) with ESUS. Methods This cohort study included all patients aged ≤ 50 years who underwent transoesophageal echocardiography for diagnostic work-up of ESUS during 1996–2008 from one tertiary center. All patients were contacted by telephone between September–November 2018 to update clinical information from medical records. The clinical outcomes of this study were incidence rates of all-cause and cardiovascular mortality, recurrent stroke/TIA, new-onset clinical AF, and ischemic vascular events. Results In total, 108 patients (57% female, mean age 40 ± 7.2 years [range 19–50 years], n = 72 stroke) were included. Across clinical follow-up (median 13[IQR 10–16] years), 24 patients died ( n = 14 cardiovascular). The 15-year incidence rate of recurrent stroke/TIA was 15% (incidence rate = 1.09[95%CI 0.54–1.65]/100 patient-years) and a 5.5% incidence of new-onset clinical AF (incidence rate = 0.44[95%CI 0.09–0.79]/100 patient-years) following ESUS. Conclusions The incidence of recurrent stroke/TIA is relatively high during long-term clinical follow-up of young patients with ESUS. In contrast, new-onset clinical AF is relatively low and therefore may not play an important part in the pathophysiology of first-ever and recurrent stroke/TIA of these patients.

Multicenter Cohort Study

Introduction: The Stroke Prevention Trial in Sickle Cell Anemia (STOP) changed standards of care for stroke screening and treatment of high-risk children with sickle cell anemia (SCA), reducing the risk of ischemic stroke. However, the incidence of hemorrhagic stroke in young patients with SCA in the post-STOP era remains poorly characterized. Methods: The Post-STOP multicenter cohort study collected follow-up data from prior participants (all with SCA) of the STOP or STOP II clinical trials. From 01/2012 – 05/2014, medical records analysts abstracted clinical, imaging and laboratory data collected after the STOP studies ended at 19 of the 26 original sites. Two stroke neurologists reviewed data to confirm hemorrhagic stroke, defined as primary spontaneous intracerebral, subarachnoid or intraventricular hemorrhage; we excluded traumatic hemorrhage or hemorrhagic conversion of ischemic infarcts. Incidence rates among those with no prior hemorrhagic stroke at the start of Post-STOP were calculated using survival analysis techniques. Results: Follow-up data were collected from 2,851 of 3,835 participants participated in the STOP trials. Patients (51% male) were a median age of 10.4 years (interquartile range [IQR] 6.8-14.1) at the start of Post-STOP. Over a median of 10.3 (IQR 7.3-11.4) years of follow-up, 35 patients with hemorrhagic stroke were identified (Table 1). The incidence rate was 63 per 100,000 person-years overall (95% CI 45-87). Stratified by age, the incidence rate per 100,00 person-years was 50 (95% CI 34-75) for children less than 18 years old and 134 (95% CI 74-243) for adults over the age of 50. Conclusion: In our cohort, we observed that the risk of hemorrhagic stroke in patients with SCA rises as patients age, most sharply after the first decade of life. Structural vascular abnormalities such as moyamoya syndrome and aneurysms are common etiologies for hemorrhage and screening may be warranted.

Secondary Malignancies

Abstract Abstract 3746 Introduction: The increase of overall survival in chronic myeloid leukemia (CML) requires closer long-term observation in the face of a potential carcinogenicity of tyrosine kinase inhibitors (TKIs). Preclinical studies with imatinib in rats showed neoplastic changes in kidneys, urinary bladder, urethra, preputial and clitoral glands, small intestine, parathyroid glands, adrenal glands, and nonglandular stomach. Two epidemiologic studies on patients with chronic myeloproliferative neoplasms (CMPN) and CML (Frederiksen H et al., Blood 2011; Rebora P et al., Am J Epidemiol 2010) found an increased risk of secondary malignancies compared with the general population independent of treatment. In contrast, in a recent analysis of patients with CML and CMPN treated with TKI (Verma D et al., Blood 2011) a decreased risk of secondary malignancies was reported. Aims: To further elucidate the risk of TKI treated CML patients for the development of secondary malignancies we analysed data of the CML study IV, a randomized 5-arm trial (imatinib 400 mg vs. imatinib 800 mg vs. imatinib 400 mg in combination with interferon alpha vs. imatinib 400 mg in combination with AraC vs. imatinib 400 mg after interferon failure). Patients and methods: From February 2002 to April 2012, 1551 CML patients in chronic phase were randomized, 1525 were evaluable. Inclusion criteria allowed the history of primary cancer if the disease was in stable remission. Forty-nine malignancies were reported in 43 patients before the diagnosis of CML. If relapses occurred within 5 years after diagnosis of primary cancer they were not considered for further analysis. Median follow-up was 67.5 months. Age-standardized incidence rates were calculated from the age-specific rates using the European standard population (1976). Results: In total, 67 secondary malignancies in 64 patients were found in CML patients treated with TKI (n=61) and interferon alpha only (n=3). Twelve of these patients developed neoplasms after diagnosis of a primary cancer before diagnosis of CML, 5 patients with metastases or recurrence of the first malignancy (range of diagnosis 5–19 years after primary cancer). Median time to secondary malignancy was 2.5 years (range 0.1–8.3 years). The types of neoplasms were: prostate (n=9), colorectal (n=6), lung (n=6), non Hodgkin's lymphoma (NHL; n=7), malignant melanoma (n=5), skin tumors (basalioma n=4 and squamous cell carcinoma n=1), breast (n=5), pancreas (n=4), kidney (n=4), chronic lymphocytic leukemia (n=3), head and neck (n=2), biliary (n=2), sarcoma (n=2), and esophagus, stomach, liver, vulva, uterus, brain, cancer of unknown origin (each n=1). With these numbers the age-standardized incidence rates of secondary malignancies in CML patients were calculated: 534 cases per 100,000 for men (confidence interval [350;718]), and 582 for women (confidence interval [349;817]). The incidence rates of the general population in Germany were 450 and 350 cases, respectively (“Krebs in Deutschland 2007/2008”, 8th ed., Robert Koch Institute, 2012). The incidence rate of NHLs was higher for CML patients than for the general population but this is not significant. Conclusions: In our cohort, the incidence rate of secondary neoplasms in CML patients was slightly increased compared to the general population. The most common secondary malignancies in CML patients under treatment were cancers of the skin, prostate, colon, lung and NHL. Since the occurrence of secondary neoplasia increases over time, long-term follow-up of CML patients is warranted. Disclosures: Müller: Novartis, BMS: Consultancy, Honoraria, Research Funding.

Electronic Health Record Data

ObjectivesTo determine the association of long-term use of antipsychotics with the risk of dyslipidaemia.DesignA hospital-based cohort study.SettingElectronic health record data of adult mental health inpatients in all 19 specialised psychiatric hospitals in Beijing from 1 January 2005 to 31 December 2018 was obtained.ParticipantsParticipants were inpatients aged 18 years or older with at least two admissions, excluding those with diagnosed dyslipidaemia and fatty liver at the first admission. We included 22 329 adult inpatients with no dyslipidaemia and fatty liver at baseline. The exposure was antipsychotics use, defined as antipsychotics prescription in the treatment procedures of medical record preceding dyslipidaemia diagnosis during the follow-up period. 15 930 (71.34%) had antipsychotics use, and 6399 (28.66%) never had antipsychotics use. We used the length of follow-up as proxy for the duration of antipsychotics exposure.Primary outcome measuresThe primary outcome was newly recorded dyslipidaemia defined by International Classification of Diseases, 10th Revision codes.Results4069 inpatients had newly recorded dyslipidaemia during 73 418.07 person-years, the incidence rate was 5.54 per 100 person-years. The incidence rate was 7.22 per 100 person-years in the exposed group and 3.43 per 100 person-years in the unexposed group. Results of multivariate analysis showed that antipsychotics use was associated with higher risk of dyslipidaemia (adjusted HR, aHR 2.41, 95% CI 2.24 to 2.59, p<0.001), regardless of the duration of antipsychotics use. Inpatients aged 18–29 years had higher risk of dyslipidaemia (aHR 3.38, 95% CI 2.77 to 4.12, p=0.004) than those in other age groups. Inpatients without hypertension had substantially higher risk of dyslipidaemia after antipsychotic exposure.ConclusionsBoth short-term and long-term antipsychotics use was associated with higher risk of dyslipidaemia among Chinese inpatients with mental illness. Dyslipidaemia was especially prominent in young patients and those without hypertension.

Objective This study aimed at identifying the incidence, predictors, and impact on long-term mortality and dementia of early-onset delirium in a cohort of patients with spontaneous intracerebral hemorrhage. Methods We prospectively recruited consecutive patients in the Prognosis of InTra-Cerebral Hemorrhage (PITCH) cohort and analyzed incidence rate of early-onset delirium (i.e. during the first seven days after intracerebral hemorrhage onset) with a competing risk model. We used a multivariable Fine-Gray model to identify baseline predictors, a Cox regression model to study its impact on the long-term mortality risk, and a Fine-Gray model adjusted for pre-specified confounders to analyze its impact on new-onset dementia. Results The study population consisted of 248 patients (mean age 70 years, 54% males). Early-onset delirium incidence rate was 29.8% (95% confidence interval (CI) 24.3–35.6). Multivariate analysis showed that pre-existing dementia (subhazard ratio (SHR) 2.08, 95%CI 1.32–3.32, p = 0.002), heavy alcohol intake (SHR 1.79, 95%CI 1.13–2.82, p = 0.013), and intracerebral hemorrhage lobar location (SHR 1.56, 95%CI 1.01–2.42, p = 0.049) independently predicted early-onset delirium. Median follow-up was 9.5 years. Early-onset delirium was associated with higher mortality rates during the first five years of follow-up (HR 1.52, 95%CI 1.00–2.31, p = 0.049), but did not predict new-onset dementia (SHR 1.31, 95%CI 0.60–2.87). Conclusion Early-onset delirium is a frequent complication after intracerebral hemorrhage; it is associated with markers of pre-existing brain vulnerability and with higher mortality risk, but not with higher dementia rates during long-term follow-up.

ABSTRACTAIMThe CoKids study aimed to estimate the community incidence of symptomatic and asymptomatic SARS-CoV-2 in children and parents and to assess the symptomatology of SARS-COV-2 infections relative to SARS-CoV-2 negative respiratory episodes.METHODSIn this prospective study, households with at least one child <18 years were recruited from three existing Dutch cohorts. Participation included SARS-CoV-2 screening at 4-6 weeks intervals for all household members during 23 weeks of follow-up and active reporting of new onset respiratory symptoms until July 1st 2021. Follow-up was temporarily intensified following new onset respiratory symptoms in a household member or a SARS-CoV-2 positive screening test and included daily symptom recording, repeated PCR testing (nose-throat, saliva and fecal samples) and SARS-CoV-2 antibody measurement (paired dried blood spots) in all household members. Age-stratified incidence rates for SARS-CoV-2 positive and negative episodes were calculated. Symptomatology and disease burden of respiratory episodes were compared by SARS-CoV-2 status and age.RESULTSIn total 307 households were enrolled including 1209 subjects. We detected 64 SARS-CoV-2 positive and 118 SARS-CoV-2 negative respiratory outbreaks. The highest incidence rate was found in children <12 years for SARS-CoV-2 negative episodes (0.93/ person-year (PY); 95%CI: 0.88-0.96). The SARS-CoV-2 incidence in this age-group was 0.21/PY for confirmed only, and 0.41/PY if probable cases were included. SARS-CoV-2 incidence did not differ by age group (p>0.27). Nasal congestion/runny nose, with or without cough and fatigue were the three most prevalent symptom clusters for both SARS-CoV-2 positive and negative respiratory episodes. Among children, no differences were observed in the symptomatology and severity of SARS-CoV-2 positive versus negative respiratory episodes, whereas among adults, SARS-CoV-2 positive episodes had a higher number and severity of symptoms and with a longer duration p<0.001).CONCLUSIONUsing active, longitudinal household follow up, we detected a high incidence rate of SARS-CoV-2 infections in children that was similar to adults. The findings suggest that after 20 months of COVID-19 pandemic, up to 2/3 of Dutch children < 12 years have been infected with SARS-CoV-2. Symptomatology and disease severity of SARS-CoV-2 in children is similar to respiratory illness from other causes. In adults, SARS-COV-2 positive episodes are characterized by more and prolonged symptoms, and higher severity. These findings may assist decisions on COVID-19 policies targeting children.

Abstract Aims Atrioventricular block (AVB) of unknown aetiology is rare in the young, and outcome in these patients is unknown. We aimed to assess long-term morbidity and mortality in young patients with AVB of unknown aetiology. Methods and results We identified all Danish patients younger than 50 years receiving a first pacemaker due to AVB between January 1996 and December 2015. By reviewing medical records, we included patients with AVB of unknown aetiology. A matched control cohort was established. Follow-up was performed using national registries. The primary outcome was a composite endpoint consisting of death, heart failure hospitalization, ventricular tachyarrhythmia, and cardiac arrest with successful resuscitation. We included 517 patients, and 5170 controls. Median age at first pacemaker implantation was 41.3 years [interquartile range (IQR) 32.7–46.2 years]. After a median follow-up of 9.8 years (IQR 5.7–14.5 years), the primary endpoint had occurred in 14.9% of patients and 3.2% of controls [hazard ratio (HR) 3.8; 95% confidence interval (CI) 2.9–5.1; P < 0.001]. Patients with persistent AVB at time of diagnosis had a higher risk of the primary endpoint (HR 10.6; 95% CI 5.7–20.0; P < 0.001), and risk was highest early in the follow-up period (HR 6.8; 95% CI 4.6–10.0; P < 0.001, during 0–5 years of follow-up). Conclusion Atrioventricular block of unknown aetiology presenting before the age of 50 years and treated with pacemaker implantation was associated with a three- to four-fold higher rate of the composite endpoint of death or hospitalization for heart failure, ventricular tachyarrhythmia, or cardiac arrest with successful resuscitation. Patients with persistent AVB were at higher risk. These findings warrant improved follow-up strategies for young patients with AVB of unknown aetiology.

Abstract Background New-onset atrial fibrillation (NOAF) complicating acute myocardial infarction (AMI) has been associated with poor survival, but the clinical implication of NOAF on subsequent heart failure (HF) is still not well studied. We aimed to investigate the relationship between NOAF following AMI and HF hospitalization. Methods This retrospective cohort study was conducted between February 2014 and March 2018, using data from the New-Onset Atrial Fibrillation Complicating Acute Myocardial Infarction in ShangHai registry, where all participants did not have a documented AF history. Patients with AMI who discharged alive and had complete echocardiography and follow-up data were analyzed. The primary outcome was HF hospitalization, which was defined as a minimum of an overnight hospital stay of a participant who presented with symptoms and signs of HF or received intravenous diuretics. Results A total of 2075 patients were included, of whom 228 developed NOAF during the index AMI hospitalization. During up to 5 years of follow-up (median: 2.7 years), 205 patients (9.9%) experienced HF hospitalization and 220 patients (10.6%) died. The incidence rate of HF hospitalization among patients with NOAF was 18.4% per year compared with 2.8% per year for those with sinus rhythm. After adjustment for confounders, NOAF was significantly associated with HF hospitalization (hazard ratio [HR]: 3.14, 95% confidence interval [CI]: 2.30–4.28; p<0.001). Consistent result was observed after accounting for the competing risk of all-cause death (subdistribution HR: 3.06, 95% CI: 2.18–4.30; p<0.001) or performing a propensity score adjusted multivariable model (HR: 3.28, 95% CI: 2.39–4.50; p<0.001). Furthermore, the risk of HF hospitalization was significantly higher in patients with persistent NOAF (HR: 5.81; 95% CI: 3.59–9.41) compared with that in those with transient NOAF (HR: 2.61; 95% CI: 1.84–3.70; p interaction = 0.008). Conclusion NOAF complicating AMI is strongly associated with an increased long-term risk of heart.

SummaryWhether atrial fibrillation (AF) is associated with an increased risk of venous thromboembolism (VTE) remains controversial. From Longitudinal Health Insurance Database 2000 (LHID2000), we identified 11,458 patients newly diagnosed with AF. The comparison group comprised 45,637 patients without AF. Both cohorts were followed up to measure the incidence of deep-vein thrombosis (DVT) and pulmonary embolism (PE). Univariable and multivariable competing-risks regression model and Kaplan-Meier analyses with the use of Aelon-Johansen estimator were used to measure the differences of cumulative incidences of DVT and PE, respectively. The overall incidence rates (per 1,000 person-years) of DVT and PE between the AF group and non-AF groups were 2.69 vs 1.12 (crude hazard ratio [HR] = 1.92; 95 % confidence interval [CI] = 1.54-2.39), 1.55 vs 0.46 (crude HR = 2.68; 95 % CI = 1.97-3.64), respectively. The baseline demographics indicated that the members of the AF group demonstrated a significantly older age and higher proportions of comorbidities than non-AF group. After adjusting for age, sex, and comorbidities, the risks of DVT and PE remained significantly elevated in the AF group compared with the non-AF group (adjusted HR = 1.74; 95 %CI = 1.36-2.24, adjusted HR = 2.18; 95 %CI = 1.51-3.15, respectively). The Kaplan-Meier curve with the use of Aelon-Johansen estimator indicated that the cumulative incidences of DVT and PE were both more significantly elevated in the AF group than in the non-AF group after a long-term follow-up period (p<0.01). In conclusion, the presence of AF is associated with increased risk of VTE after a long-term follow-up period.

BackgroundSnake bite continues to be a significant cause of acute kidney injury (AKI) in India. There is paucity of data regarding long-term outcomes of such patients. In this study, we aim to assess the prognosis and long-term renal outcomes of such patients.MethodsWe analysed the hospital records of snake envenomation-induced AKI from January 2015 to December 2018. Predictors of in-hospital mortality were assessed. Survivors were advised to visit follow-up clinic to assess their kidney function.ResultsThere were 769 patients with evidence of envenomation and of them, 159 (20.7%) had AKI. There were 112 (70.4%) males. Mortality occurred in 9.4% of patients. Logistic regression analysis identified shock (OR 51.949, 95% CI 4.297 to 628.072) and thrombocytopenia (OR 27.248, 95% CI 3.276 to 226.609) as predictors of mortality. Forty-three patients attended the follow-up. The mean follow-up duration was 30.4±15.23 months. Adverse renal outcomes (eGFR <60 mL/min/1.73 m2 or new-onset hypertension (HTN) or pre-HTN or urine protein creatinine ratio >0.3) occurred in 48.8% of patients. Older age (mean age (years) 53.3 vs 42.8, p=0.004) and longer duration on dialysis (median duration (days) 11.5 vs 5, p=0.024) were significantly associated with adverse renal outcomes.ConclusionsThe incidence of AKI in snake envenomation was 20.7%. The presence of shock and thrombocytopenia were associated with mortality. Adverse renal outcomes occurred in 48.8% of patients in the long term.
