Tóm tắt

Bệnh tiểu đường (DM) và giang mai thần kinh (NS) đều có thể làm tổn thương hàng rào máu-não (BBB). Có vẻ như những bệnh nhân không mắc giang mai thần kinh (non-NS) với mức HbA1c cao có khả năng phát triển thành NS. Tuy nhiên, mối tương quan của mức HbA1c với sự gián đoạn của BBB ở bệnh nhân giang mai (non-NS) vẫn chưa rõ ràng. Trong nghiên cứu này, chúng tôi đã sử dụng công nghệ cộng hưởng từ tăng cường tương phản động (DCE-MRI) để định lượng tính thấm của BBB tại các vùng khác nhau ở bệnh nhân giang mai (non-NS) và phát hiện một số dấu hiệu phân tử trong dịch não tủy (CSF). Chúng tôi nhận thấy rằng các giá trị tính thấm của BBB tại hippocampus, chất trắng, và vỏ não thùy thái dương dưới có mối liên hệ với tỷ lệ albumin (Qalb), nồng độ interleukin IL-6 và IL-10 trong CSF. Hơn nữa, sự phá hủy BBB trong chất trắng có liên quan đến nồng độ sICAM-1 và sVCAM-1 trong CSF. Kết luận, dữ liệu của chúng tôi gợi ý rằng tính toàn vẹn của BBB có thể dễ bị tổn thương ở bệnh nhân giang mai (non-NS), cũng như ở những bệnh nhân có mức HbA1c cao, và đặc biệt quan trọng là phải kiểm soát lượng đường huyết ở những bệnh nhân này.
