## TL;DR

This study examines how IL-18 and IL-18BP levels in bone marrow relate to disease severity and immune cell function in myelodysplastic syndrome patients.

## Contribution

The study reveals a novel link between fIL-18 levels, disease severity, and CD8+ T cell function in MDS.

## Key findings

- MDS patients had higher IL-18, IL-18BP, and fIL-18 levels compared to IDA patients.
- fIL-18 levels were negatively correlated with MDS-IPSS scores and positively correlated with CD8+ T cell function.
- CD8+ T cells in MDS patients showed reduced IL-18Rα expression compared to IDA patients.

## Abstract

分析IL-18、IL-18结合蛋白（IL-18BP）在骨髓增生异常综合征（MDS）患者骨髓液中的表达水平及临床意义。

纳入2020年7月至2021年2月天津医科大学总医院血液科收治的初诊MDS患者43例，对照组包括急性髓系白血病（AML）患者14例、缺铁性贫血（IDA）患者25例，检测骨髓上清中IL-18和IL-18BP水平，分析其与MDS的严重程度、CD8+ T细胞及NK细胞功能的相关性。

MDS患者骨髓上清中IL-18、IL-18BP和游离IL-18（fIL-18）的水平均高于IDA组，fIL-18的水平与MDS-IPSS评分呈线性负相关。MDS患者CD8+ T细胞表面IL-18受体（IL-18Rα）表达低于IDA组，fIL-18及IL-18Rα水平均与MDS患者CD8+ T细胞功能呈正相关。

IL-18在MDS患者骨髓微环境中表达增加，但由于IL-18BP的存在导致fIL-18相对减少，与MDS疾病严重程度和CD8+ T细胞功能减低有关。
