ObjectiveTo generate a score which clinically identifies surface-directed autoantibodies in adults with new-onset focal epilepsy, and evaluate the value of immunotherapy in this clinical setting.MethodsProspective clinical and autoantibody evaluations in a cohort of 219 consecutive patients with new-onset focal epilepsy.Results10.5% (23/219) of people with new-onset focal epilepsy had detectable serum autoantibodies to known or novel cell surface antigenic targets. 9/23 with autoantibodies were diagnosed with encephalitis, by contrast to 0/196 without autoantibodies (p<0.0001). Multivariate analysis identified six features which predicted autoantibody positivity (area under the curve=0.83): age ≥54 years, ictal piloerection, lowered self-reported mood, reduced attention, MRI limbic system changes and the absence of conventional epilepsy risk factors. 11/14 (79%) patients with detectable autoantibodies, but without encephalitis, showed excellent long-term outcomes (modified Rankin Score=0) despite no immunotherapy. These outcomes were superior to those of immunotherapy-treated patients with confirmed autoantibody-mediated encephalitis (p<0.05).ConclusionsSeizure semiology, cognitive and mood phenotypes, alongside inflammatory investigation findings, aid the identification of surface autoantibodies among unselected people with new-onset focal epilepsy. The excellent immunotherapy-independent outcomes of autoantibody-positive patients without encephalitis suggests immunotherapy administration should be guided by clinical features of encephalitis, rather than autoantibody positivity. Our findings suggest that, in this cohort, immunotherapy-responsive seizure syndromes with autoantibodies largely fall under the umbrella of autoimmune encephalitis.

Abstract Background Autoimmune systemic inflammatory diseases are associated with an increased risk of cardiovascular disease, particularly myocardial infarction (MI). However, there are limited data on the prevalence and effects of inflammatory disease among U.S. adults who experience an MI at a young age. Purpose We sought to determine the prevalence and prognostic value of inflammatory disease in U.S. adults who experience an MI at a young age. Methods The YOUNG-MI registry is a retrospective cohort study of consecutive patients who experienced a Type 1 MI at or below the age of 50 years from 2000 to 2016 at two large medical centers. A diagnosis of rheumatoid arthritis (RA), psoriasis (PsO), systemic lupus erythematosus (SLE), or inflammatory arthritis was determined through physician review of electronic medical records (EMR). Demographic information, presence of cardiovascular (CV) risk-factors, medical procedures, and medications upon discharge were also ascertained from the EMR. Incidence of death was determined using a combination of EMR and national databases. Cox proportional hazard modeling was performed on a sub-sample following Mahalanobis Distance matching on age, sex, and CV risk factors. Results The cohort consisted of 2097 individuals (median age 45 years, 19% female, 53% ST-elevation MI). Among these, 53 (2.5%) individuals possessed a diagnosis of systemic inflammatory disease at or before their index MI (23% SLE, 9% RA, 64% PsO, 4% inflammatory arthritis). When compared to the remainder of the cohort, patients with a diagnosis of systemic inflammatory disease were more likely to be female (36% vs 19%, p=0.004) and be diagnosed with hypertension (62% vs 46%, p=0.025). There was, however, no significant difference in the prevalence of other CV risk factors – diabetes, smoking, dyslipidemia – or a family history of premature coronary artery disease. Despite these similarities, patients with inflammatory disease were less likely to be prescribed aspirin (88% vs 95%, p=0.049) or a statin (76% vs 89%, p=0.008) upon discharge. Over a median follow-up of 11.2 years, patients with inflammatory disease experienced an increased risk of all-cause mortality when compared with the full-cohort (Figure). Compared to the matched sample (n=138), patients with systemic inflammatory disease exhibited an increased risk of all-cause mortality (HR=2.68, CI [1.18 to 6.07], p=0.018), which remained significant after multivariable adjustment for length of stay and GFR (HR=2.38, CI [1.02 to 5.54], p=0.045). Conclusions Among individuals who experienced an MI at a young age, approximately 2.5% had evidence of a systemic inflammatory disease at or before their MI. When compared with a population of individuals with similar cardiovascular risk profiles, those with inflammatory disease had higher rates of all-cause mortality. Our findings suggest that the presence of a systemic inflammatory disorder is independently associated with worse long-term outcomes.

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.

A study of stroke in young patients has recently become a subject of interest. This is due to a lot of impact on the individual and society. Study of stroke in young patients can lead to therapeutical results affecting both short term and long-term outcomes. Our study is hospital based retrospective study for duration of 1 year. Thi Methods: Results: s study revealed stroke in young in 25.16% of all stroke cases, with cerebral infarction in 56% and followed by intracerebral haemorrhage in 25.64%, and cerebral venous thrombosis in 18%. The most common presenting symptom was hemiparesis. The most prevalent risk factor for stroke in young was hypertension followed by diabetes mellitus, alcohol consumption and smoking. Stroke in young requires a differe Conclusion: nt approach to investigate and treat. This is due to different underlying etilogy as compared to elderly. Although traditional risk factors are associated with stroke, behavioural pattern such as smoking and alcohol may cause and promote development of stroke in young.

Introduction: The universal classification (UC) of AMI aims to facilitate cross-study analysis, yet the long-term outcomes using UC are largely unknown. Hypothesis: We tested the hypothesis that the long-term outcome of patients with AMI is better predicted by UC than ST segment classification. Methods: We conducted a prospective study of 348 consecutive patients with AMI with mean follow-up of 30.6 months. The primary outcome was the major adverse cardiovascular events (MACE) [composite of all causes of mortality, recurrent AMI, and stroke]. Multivariate and survival analysis of MACE was performed. Results: The study population was STEMI=168, NSTEMI=180, Type 1=278, Type 2=55, Type 3=5, Type 4a=2, Type 4b=5, and Type 5=3. During follow-up 80 patients died, 31 had an AMI, and 7 had a stroke. UC correlates with the ST segment classification (p<0.005). MACE free survival was different for Type 1 and Type 2 (p=0.043), but not for STEMI and NSTEMI. There was a positive association between MACE and the quartile of peak Troponin, number of cardiovascular risk factors, and number of vascular beds affected, and an inverse relationship with the utilization of discharge cardiovascular protective medications (all p≤0.01). No such inverse relationship existed for Type 2. Conclusions: UC of AMI is a better long-term predictor of MACE. The quartile of peak Troponin levels, cardiovascular risk factors, and number of vascular beds affected are independent predictors of MACE, while cardiac medications protect against MACE, except in Type 2 patients.
