Tóm tắt

Cơn ho mãn tính là một tình trạng suy nhược ảnh hưởng đến 10–12% dân số nói chung và là một trong những nguyên nhân hàng đầu dẫn đến việc chuyển đến cơ sở điều trị thứ cấp. Nhiều tình trạng khác nhau đã được liên kết với cơn ho mãn tính, bao gồm bệnh hen suyễn, bệnh trào ngược dạ dày thực quản và hội chứng ho đường hô hấp trên. Các tình trạng viêm đường hô hấp như hen suyễn biến thể ho (CVA) và viêm phế quản dị ứng không hen suyễn (NAEB) đóng góp một phần đáng kể vào số ca trình diện với cơn ho mãn tính, với các tiêu chí chẩn đoán khác nhau và các phản ứng khác nhau với liệu pháp hen suyễn thường được sử dụng cho các chẩn đoán của họ. Các nghiên cứu cơ chế ở cả mô hình động vật và con người đã nhận diện sự nhạy cảm thần kinh tăng lên và sự nhạy cảm trung tâm kế tiếp cần thiết. Những cơ chế này bao gồm việc tăng độ nhạy của các nociceptor do viêm và sự thay đổi trong khả năng kích thích của các đầu dây thần kinh cảm giác, những thay đổi kiểu hình ở các neuron cảm giác vagi theo thời gian, và sự dẻo dai thần kinh trung ương do tăng cường tín hiệu synapse từ các afferent ngoại biên. Mục tiêu của bài tổng quan này là thảo luận về các cơ chế, sinh lý thần kinh và các phương pháp quản lý hiện có cho bệnh nhân trình diện với cơn ho mãn tính có liên quan đến bệnh hen suyễn, CVA và NAEB, đồng thời làm sáng tỏ các lĩnh vực nghiên cứu cần thiết thêm để làm rõ cơ chế gây ho ở nhóm bệnh nhân này.
