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.

Apoptosis inhibitor of macrophage (AIM) plays roles in survival of macrophages. In this study, we cloned canine AIM cDNA and observed its transcriptional expression levels in various tissues. The coding sequence of canine AIM was 1,023 bp encoding 340 amino acid residues, which had around 65% homology with those of the human, mouse and rat. Transcriptional expression of AIM was observed in the spleen, lung, liver and lymph node, which confirmed the expression of canine AIM in tissue macrophages. Moreover, AIM was highly expressed in one of the canine histiocytic sarcoma cell lines. CD36, the receptor of AIM, was also expressed in various tissues and these cell lines. These findings are useful to reveal the actual functions of canine AIM.
