Background: Different subtypes of ischemic stroke may have different risk factors, clinical features, and prognoses. This study investigated the incidence and mode of stroke recurrence in patients with a history of stroke who underwent atrial fibrillation (AF) ablation.

Methods: Of 825 patients who underwent AF ablation from 2006 to 2016, 77 patients (9.3%, median age 69 years) with a prior ischemic stroke were identified. Patients were classified as those with prior cardioembolic (CE) stroke (n = 55) and those with prior non-CE stroke (n = 22). The incidence and pattern of stroke recurrence were investigated.

Results: The incidence of asymptomatic AF (54.5% vs 22.7%;  = .011) and left atrial volume (135.8 mL vs 109.3 mL;  = .024) was greater in the CE group than in the non-CE group. Anticoagulation treatment was discontinued at an average of 28.1 months following the initial ablation in 34 (44.2%) patients. None of the patients developed CE stroke during a median 4.1-year follow-up. In the non-CE group, 2 patients experienced recurrent non-CE stroke (lacunar infarction in 1 and atherosclerotic stroke in 1); however, AF was not observed at the onset of recurrent ischemic stroke.

Conclusions: In patients with a history of stroke who underwent catheter ablation for AF, the incidence of recurrent stroke was 0.54/100 patient-years. The previous stroke in these patients may not have been due to AF in some cases; therefore, a large-scale prospective study is warranted to identify the appro priate antithrombotic therapy for the prevention of potentially recurrent stroke.

Meningoencephalitis Caused by a Campylobacter fetus in a Patient with Chronic Alcoholism.

Intern Med 2019 Aug 28;58(15):2247-2250. Epub 2019 Mar 28.

Disease Control and Prevention Center, National Center for Global Health and Medicine, Japan.

We herein report a case of Campylobacter fetus meningoencephalitis in a patient with chronic alcoholism. C. fetus is a rare cause of meningitis. The patient presented with hallucinations and monology, and alcohol withdrawal was initially suspected. After he was unsuccessfully treated for alcohol withdrawal delirium, we diagnosed C. fetus meningoencephalitis. Ampicillin monotherapy gradually improved his clinical status. A previous report stated that C. fetus infection is associated with chronic alcoholism. In patients with chronic alcoholism and disturbed consciousness, an atypical bacterial central nervous system infection, such as C. fetus meningoencephalitis, should be considered.
