摘要:

目的 探讨可溶性生长刺激表达基因2蛋白(soluble suppression of tumorigenicity 2, sST2)在肺炎支原体肺炎合并EB病毒(Epstein-Barr virus, EBV)感染患儿中的水平及其与临床指标的相关性,评估其在疾病严重程度判断中的潜在价值。方法 回顾性分析2024年4月-2025年2月于南方医科大学第七附属医院儿科住院治疗的肺炎支原体肺炎合并EBV感染患儿(MP+EB组)69例、单纯肺炎支原体感染患儿(MP组)77例及同期健康体检儿童(HC组)70例的临床资料。检测血清sST2及炎症、心肌损伤、肝功能等实验室指标,采用Spearman相关分析评估sST2与上述各指标的相关性。结果 MP+EB组血清sST2水平高于MP组及HC组(P<0.01),MP组亦高于HC组(P<0.05)。MP+EB组发热时间、住院时间、C反应蛋白、乳酸脱氢酶水平均高于MP组(P<0.05),但两组降钙素原(procalcitonin,PCT)水平差异无统计学意义(P>0.05)。在MP+EB组中,sST2与C反应蛋白、羟丁酸脱氢酶、乳酸脱氢酶、超敏C反应蛋白、天冬氨酸转氨酶、肌酸激酶同工酶MB均呈正相关(rs分别为0.805、0.792、0.806、0.768、0.394、0.523,P均<0.01),但与PCT无相关性(rs=0.133,P=0.276);在MP组中,sST2与上述指标亦呈正相关,且与PCT呈正相关(rs=0.646,P<0.01)。结论 血清sST2在肺炎支原体肺炎合并EBV感染患儿中升高,且与炎症、心肌损伤及组织损伤指标密切相关,提示sST2可能作为评估该类患儿病情严重程度的潜在生物标志物,其升高机制可能与病毒感染触发的免疫炎症通路有关。

Abstract:

Objective To investigate the level of soluble suppression of tumorigenicity 2 (sST2) in children with Mycoplasma pneumoniae pneumonia (MPP) complicated by Epstein-Barr virus (EBV) infection, and to assess its correlations with clinical indicators, thereby evaluating its potential value in determining disease severity. Methods Clinical data were retrospectively analyzed for 69 children with MPP complicated by EBV infection (MP+EB group), 77 children with Mycoplasma pneumoniae infection alone (MP group), and 70 healthy children who underwent physical examination during the same period (HC group), all hospitalized in the Department of Pediatrics of the Seventh Affiliated Hospital of Southern Medical University from April 2024 to February 2025. Serum sST2 and laboratory indicators of inflammation, myocardial injury, and liver function were measured. Spearman correlation analysis was used to evaluate the correlations between sST2 and these indicators. Results Serum sST2 levels were higher in the MP+EB group than in the MP group and HC group (P<0.01), and were also higher in the MP group than in the HC group (P<0.05). The MP+EB group had longer fever duration, longer hospital stay, and higher C-reactive protein (CRP) and lactate dehydrogenase (LDH) levels than the MP group (P<0.05), but there was no statistically significant difference in procalcitonin (PCT) levels between the two groups (P>0.05). In the MP+EB group, sST2 was positively correlated with CRP, dydroxybutyrate dehydrogenase, LDH, high-sensitivity C-reactive protein (hs-CRP), aspartate aminotransferase (AST), and creatine kinase-MB (CK-MB) (rs=0.805, 0.792, 0.806, 0.768, 0.394, and 0.523, respectively; all P<0.01), but showed no correlation with PCT (rs=0.133, P=0.276). In the MP group, sST2 was also positively correlated with the above indicators and was additionally positively correlated with PCT (rs=0.646, P<0.01). Conclusion Serum sST2 is elevated in children with MPP complicated by EBV infection and is closely associated with inflammation, myocardial injury, and tissue injury markers. These findings suggest that sST2 may serve as a potential biomarker for assessing disease severity in these patients, and that its elevation may be related to immune-inflammatory pathways triggered by viral infection.
