摘要: 目的 探讨传染性单核细胞增多症(IM)并发肝损伤患儿外周血CD19+细胞百分比及血清降钙素原(PCT)和C反应蛋白(CRP)水平变化及其临床意义。方法 2021年3月—2024年3月南京大学医学院附属盐城第一医院儿科诊治的105例IM患儿,给予更昔洛韦治疗7~14 d,给予肝损伤患儿护肝治疗。使用BD FACSCanto II流式细胞仪检测外周血CD19+细胞百分比,采用电化学发光免疫分析法检测血清PCT水平,采用免疫透射比浊法检测血清CRP水平。应用多因素logistic回归分析影响IM患儿并发肝损伤的危险因素。结果 在本组105例IM患儿中,发现肝损伤者64例(61.0%);肝损伤患儿体质指数为(21.7±1.2)kg/m2,显著小于非肝损伤组[(23.8±1.5)kg/m2,P<0.05],而肝肿大、人工喂养和临床疾病重度发生率分别为43.8%、43.8%和12.5%,均显著高于非肝损伤组的22.0%、12.2%和0.0%(均P<0.05),血清EBV DNA载量为(3.5±1.2)lg拷贝/mL,抗病毒治疗时长为(7.4±1.1)d,均显著高于或长于非肝损伤组[分别为(2.0±0.6)lg拷贝/mL和(3.6±0.5)d,P<0.05]; 肝损伤组外周血CD19+百分比和血清CRP水平分别为(8.4±1.9)%和(57.2±14.6)mg/L,均显著高于非肝损伤组[分别为(4.6±1.5)%和(12.4±2.9)mg/L,P<0.05];多因素logistic回归分析显示,肝肿大[OR=1.020, 95% CI: 1.003, 1.038, P=0.022]、人工喂养[OR=1.113, 95% CI: 1.011, 1.226, P=0.028]、用药时长[OR=10.502, 95% CI: 1.561, 70.663, P=0.016]、临床疾病严重程度[OR=1.121, 95% CI: 1.009, 1.245, P=0.033]、体质指数[OR=0.988, 95% CI: 0.978, 0.998, P=0.022]、EBV DNA水平[OR=1.777, 95% CI: 1.043, 3.028, P=0.035]、外周血CD19+细胞百分比[OR=1.471, 95% CI: 1.093, 1.980, P=0.011]和血清CRP水平[OR=2.807, 95% CI: 1.121,7.028,P=0.027]均是传染性单核细胞增多症患儿发生肝损伤的独立危险因素(P<0.05)。结论 IM患儿易并发肝损伤,临床应注意发现处于高危人群的患儿,避免过长时间的抗病毒治疗,外周血CD19+细胞百分比和血清CRP水平升高患者可能提示肝损伤的发生,而应给予积极的护肝治疗,预后良好。

Abstract: Objective To examine the changes in peripheral blood CD19+ cell percentage, along with serum procalcitonin (PCT) and C-reactive protein (CRP) levels, in children with infectious mononucleosis (IM) complicated by liver damage. Methods A total of 105 children diagnosed with IM were treated at Yancheng First Hospital, affiliated with Nanjing University Medical School, from March 2021 to March 2024. All patients received intravenous ganciclovir for one to two weeks. Those with liver injury were additionally managed with liver-protecting medicines until normalization of liver function tests. Peripheral blood CD19+ cell percentage were measured by flow cytometry (FCM), while serum procalcitonin (PCT) and C-reactive protein (CRP) levels were assayed throgh routine assays. Multivariate logistic regression analysis was used to identify risk factors associated with liver damage in children with IM. Results Among the 105 children with IM, liver injury was observed in 64 cases (61.0%). Children with liver injury had a significantly lower body mass index (BMI) [(21.7±1.2) kg/m2] compared to those without liver injury [(23.8±1.5) kg/m2, P<0.05]. The incidence of hepatomegaly, artificial feeding, and severe clinical type was markedly higher in children with liver injury (43.8%, 43.8% and 12.5%, respectively) than in those without (22.0%, 12.2% and 0.0% all P<0.05). Serum EBV DNA load was significantly elevated [(3.5±1.2) lg copies/mL] and antiviral therapy duration was longer [(7.4±1.1) days] in children with liver injury compared to those without [(2.0±0.6) lg copies/mL and (3.6±0.5) days, respectively, P<0.05]. Peripheral blood CD19+ cells percentage [(8.4±1.9) %] and serum CRP levels [(57.2±14.6) mg/L] were also significantly higher in children with liver injury than in those without [(4.6±1.5) % and (12.4±2.9) mg/L, respectively, P<0.05]. Multivariate logistic regression identified hepatomegaly [OR=1.020, 95% CI: 1.003-1.038, P=0.022], artificial feeding [OR=1.113, 95% CI: 1.011-1.226,P=0.028], duration of antiviral therapy [OR=10.502, 95% CI: 1.561-70.663,P=0.016], severe clinical type [OR=1.121, 95% CI: 1.009-1.245, P=0.033], BMI [OR=0.988, 95% CI:0.978-0.998, P=0.022], serum EBV DNA load [OR=1.777, 95% CI: 1.043-3.028, P=0.035], peripheral blood CD19+ cell percentage [OR=1.471, 95% CI: 1.093-1.980, P=0.011], and serum CRP level [OR=2.807, 95% CI: 1.121-7.028, P=0.027] as independent risk factors for liver injury in children with IM (P<0.05). Conclusion Liver injury is a potential complication in children with IM, and clinicians should carefully consider associated risk factors. Extended antiviral therapy may not be advisable, and elevated peripheral blood CD19+ cell percentages and serum CRP levels could serve as indicators of liver injury, warranting appropriate management.
