A 36-year-old man was admitted to our hospital because of urinary retention and muscle weakness affecting all 4 limbs after receiving a H1N1 09 influenza vaccination. Magnetic resonance imaging demonstrated multiple lesions in his brain and spinal cord. Furthermore, nerve conduction study showed acute sensorimotor neuropathy, and anti-GM2 antibodies were detected in his serum. Based on the temporal association and exclusion of alternative etiologies, we made a diagnosis of acute disseminated encephalomyelitis (ADEM) and Guillain-Barré syndrome (GBS). To our knowledge, this is the first case of co-morbid ADEM and GBS after influenza vaccination with positive anti-ganglioside antibodies.

Aims: We aimed to assess the prognostic impact of hyperhomocysteinemia (HHcy) on the recurrent vascular event risk in stroke patients with or without chronic kidney disease (CKD). Methods: In this prospective observational study, 621 patients (mean age, 69.5 years; male, 62.2%) with ischemic stroke or transient ischemic attack were consecutively enrolled within 1 week of onset and followed-up for 1 year. HHcy was defined as elevated levels of fasting total homocysteine >15 µmol/L. CKD was defined as an estimated glomerular filtration rate of <60 mL/min/1.73 m2 or a history of renal replacement therapy. The primary outcome was a composite of major adverse cardiovascular events (MACEs), including nonfatal stroke, nonfatal acute coronary syndrome, major peripheral artery disease, and vascular death. Results: The prevalence of HHcy was 18.5%. Patients with HHcy were more likely to have intracranial (37.4% versus 24.8%; p=0.008) and extracranial (20.9% versus 13.0%; p=0.037) artery stenosis than were those without HHcy. At 1 year, patients with HHcy were at a greater risk of MACE than were those without HHcy (annual rate, 17.8% versus 10.4%; log-rank p=0.033). In the Cox proportional hazard regression models, HHcy was independently associated with an increased risk of MACE in patients with CKD (adjusted hazard ratio [HR], 2.06; 95% confidence interval [CI], 1.02-4.20), whereas HHcy was not predictive of MACE in those without CKD (adjusted HR, 1.00; 95% CI, 0.30-3.32). Conclusions: Elevated levels of serum homocysteine can be an important modifiable risk factor in stroke patients with CKD, but not in those without CKD.

Background: This study aimed to identify the association between long term functional outcomes and acute ischemic stroke (AIS) in patients with heart failure (HF) in Japan and whether 1-year event risks can be related to these patients.Methods and Results: This was a prospective observational study, and 651 patients registered in the Tokyo Women’s Medical University Stroke Registry were classified into the HF and non-HF groups. Functional outcome at 1 year after stroke onset was defined as either good (modified Rankin Scale [mRS] score of 0–2) or poor (mRS score of 3–6). The primary outcome was a composite of major adverse cardiovascular events (MACE), including non-fatal stroke, non-fatal acute coronary syndrome, and vascular death. Patients with HF had a higher poor functional outcome rate at 1 year than those without HF (54.7% vs. 28.2%, P<0.001). Multivariate logistic regression analysis also demonstrated the prevalence of HF was an independent predictor of an mRS score of ≥3 at 1 year after stroke onset (odds ratio, 1.05; 95% confidence interval, 1.00–1.10; P=0.036). Furthermore, patients with HF tended to have a higher risk of MACE and all-cause mortality than those without HF.Conclusions: AIS patients with HF were associated with poor functional outcome at the 1-year follow up. Further multicenter studies involving a larger number of patients are warranted to verify these results.

Aims: We have previously reported 5-year follow-up data on the TIAregistry.org, an international prospective cohort in patients with transient ischemic attack (TIA) or minor stroke. We conducted a Japanese subgroup analysis because outcomes and predictors might differ according to ethnicities and regions. In this study, we compared the baseline and 5-year follow-up data of Japanese and non-Japanese patients with TIA or minor stroke.Methods: Patients with TIA or minor ischemic stroke within 7 days after the onset were classified into two groups based on ethnicity, Japanese (n=345) and non-Japanese (n=3502); further, 5-year event rates were compared between the two groups. We also determined predictors of 5-year stroke for both groups. Results: Vascular death and death from any cause were identified to be less prevalent, unlike stroke and intracranial hemorrhage, which was determined to be more prevalent in Japanese than in non-Japanese patients. Five-year rate of stroke was significantly higher in Japanese patients. Cumulative stroke and major cardiovascular event rates did not decline but instead linearly increased from 1 to 5 years in both groups. Baseline risk factors for 5-year stroke were as follows: age, diabetes, history of stroke or TIA, and congestive heart failure in Japanese patients. Independent predictors of 5-year stroke were large artery atherosclerosis, congestive heart failure, diabetes, and age in Japanese patients. Conclusions: Recurrent stroke and intracranial hemorrhage were determined to be more prevalent at 5 years after TIA or minor stroke in Japanese patients than in non-Japanese patients. Strategies to mitigate the long-term risks of stroke, aside from adherence to current guidelines, should take Japanese-patient-specific residual risks into account.
