Increased Plasma Cell-Free DNA Level during HTNV Infection: Correlation with Disease Severity and Virus Load

Cell-free DNA (cf-DNA) in blood represents a promising DNA damage response triggered by virus infection or trauma, tumor, etc. Hantavirus primarily causes two diseases: haemorrhagic fever with renal syndrome (HFRS) and Hantavirus cardiopulmonary syndrome (HCPS), depending on different Hantavirus species. The aim of this study was to evaluate plasma cf-DNA levels in acute phase of HFRS, and to correlate plasma cf-DNA with disease severity and plasma Hanttan virus (HTNV) load. We observed the appearance of cf-DNA in 166 plasma samples from 76 HFRS patients: the plasma cf-DNA levels peaked at the hypotensive stage of HFRS, and then decreased gradually. Until the diuretic stage, there was no significant difference in plasma cf-DNA level between patients and the healthy control. Exclusively in the febrile/hypotensive stage, the plasma cf-DNA levels of severe/critical patients were higher than those of the mild/moderate group. Moreover, the plasma cf-DNA value in the early stage of HFRS was correlated with HTNV load and disease severity. In most of the patients, plasma cf-DNA displayed a low-molecular weight appearance, corresponding to the size of apoptotic DNA. In conclusion, the plasma cf-DNA levels were dynamically elevated during HFRS, and correlated with disease severity, which suggests that plasma cf-DNA may be a potential biomarker for the pathogenesis and prognosis of HFRS.

Changes in Plasma Adiponectin Concentrations in Patients With Hemorrhagic Fever With Renal Syndrome: An Observational Prospective Study

The objective is to observe the changes in plasma adiponectin (APN) and its predictive capacity for disease severity and prognosis of hemorrhagic fever with renal syndrome (HFRS).One hundred and five patients who were treated at our center between October 2011 and December 2012 were randomly enrolled in this study. The patients were divided into a mild-type group, a moderate-type group, a severe-type group, and a critical-type group according to the HFRS criteria for clinical classification. Ninety-three plasma samples from the patients in the acute stage and 78 samples from the patients in the convalescent stage were obtained, and 28 samples from healthy subjects were obtained as controls. The concentrations of APN were detected using the enzyme-linked immunosorbent assay. The levels of white blood cells, platelets, hematocrit, albumin, blood urea nitrogen, serum creatinine, and uric acid in the samples were routinely tested. The levels of APN among the different types were compared; the correlation between APN and the laboratory parameters was analyzed. The predictive effectiveness for prognosis of APN and the laboratory parameters as mentioned above were evaluated using the receiver operating characteristic curve analysis.The levels of APN in the mild- and moderate-type patients in the acute stage were significantly higher than the severe-type and control (P < 0.05) and decreased with the severity of the disease, while there were no obvious difference among severe-, critical-type and control groups. The levels of APN in patients in the convalescent stage were higher than the control group (P < 0.05), and the APN levels of the critical-type group were higher compared with the mild-type groups (P < 0.05). Adiponectin was negatively correlated with white blood cells and hematocrit and positively correlated with platelets, albumin, and uric acid (P < 0.001). Adiponectin showed no statistical significance for predicting prognosis, with the area under the curve equal to 0.609 (95% CI: 0.237–0.745, P = 0.215).Adiponectin can be considered as a novel biomarker for disease severity in patients with HFRS, while it seems to have no predictive capacity for prognosis of HFRS.     

Interleukin-18: a strong predictor of the extent of coronary artery disease in patients with unstable angina

The aim of this study was to confirm that plasma interleukin (IL)-18 level is associated with the extent of coronary artery disease in unstable angina patients. Previous studies have shown that patients with unstable angina have significantly higher plasma IL-18 levels than healthy volunteers. However, the association between IL-18 and the extent of coronary artery atherosclerosis in patients with unstable angina remains unclear. Plasma concentrations of IL-18 and high-sensitivity C-reactive protein (hs-CRP) were measured in 166 consecutive patients admitted for coronary arteriography. One hundred and eighteen patients with unstable angina had coronary artery disease (coronary artery disease group; severity score: 2.32 ± 1.47; Gensini score: 31.3 ± 25.9), and 48 patients with coronary risk factors and without coronary artery lesions served as the risk control group. Plasma levels of IL-18 were higher in the coronary artery disease group than in the risk control group (P = 0.062). Additionally, plasma levels of IL-18 were significantly higher in 77 coronary artery disease patients with severity score ≥2 than in the risk control group (242.3 ± 110.6 vs 209.8 ± 120.3 pg/ml, P = 0.016). By univariate analysis, log-transformed plasma IL-18 concentration was positively correlated with coronary artery disease severity score (r = 0.244, P = 0.009). By multiple regression analyses, the association between coronary artery disease severity score and IL-18 remained significant (β = 0.733, P = 0.017) when controlling for age, diabetes mellitus and left ventricular ejection fraction. Additionally, coronary artery disease severity score was greater in the highest tertile (>246 pg/ml) of plasma IL-18 levels than in the middle (176–246 pg/ml) and the lowest (<176 pg/ml) tertiles (2.79 ± 1.52 vs 2.05 ± 1.08 vs 2.13 ± 1.66, P = 0.028). Of note, plasma hs-CRP level had no significant correlation with coronary artery severity. Plasma IL-18 level is associated with the extent of coronary artery disease in unstable angina patients, suggesting the link between IL-18 and coronary artery atherosclerosis in these patients.

Interleukin-18 is associated with the severity of atopic dermatitis

BackgroundInterleukin (IL)-18 acts as both a Th1 and Th2 cytokine, but its association with allergic diseases remains unclear. The aim of the present study was to measured plasma IL-18 and serum IgE levels in atopic children to evaluate how IL-18 is associated with allergic diseases.MethodsThe plasma IL-18 and serum IgE levels in 51 atopic children, 28 healthy control children and 14 healthy control adults were measured by enzyme-linked immunosorbent assay (ELISA). The 5' end of the IL-18 gene of 48 atopic children and 20 healthy control children was sequenced.ResultsThe plasma IL-18 level was significantly elevated in children with bronchial asthma and/or atopic dermatitis. Plasma IL-18 levels in the moderate or severe atopic dermatitis group were significantly higher than those in either the control group or the mild atopic dermatitis group. There was a positive correlation between plasma IL-18 and serum IgE levels. Three allelic combinations of polymorphisms in the IL-18 gene promoter region were observed. There was no significant difference in the plasma IL-18 levels between groups carrying these genotypes. However, bronchial asthma patients had significantly higher frequencies of the − 137 G/G genotype than did control children.ConclusionsThe plasma IL-18 level was elevated, particularly in patients with atopic dermatitis. As the clinical severity of atopic dermatitis increased, the plasma IL-18 level also tended to increase. These findings suggest that IL-18 may be associated with the severity of atopic dermatitis.     

阻塞性睡眠呼吸暂停低通气综合征患者血浆白细胞介素-18水平与动脉粥样硬化的关系

目的 探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者血浆IL-18水平与动脉粥样硬化的关系.方法 选取就诊的男性OSAHS患者52例,年龄26～77岁,分为轻度组16例,中度组18例,重度组18例,另选对照组18例.对其中OSAHS组中20例中重度患者进行持续气道内正压(CPAP)治疗,并检测颈动脉内膜中膜厚度(IMT),测定血浆白细胞介素-18(IL-18)的水平.采用方差分析、配对t检验及Pearson相关分析进行统计学处理.结果 轻度、中度和重度OSAHS组的IL-18水平分别为(352±76)ng/L、(600±84)ng/L和(798±110)ng/L,均明显高于对照组的(250±76)ng/L,且OSAHS各组间均有明显差别.重度OSAHS组颈动脉IMT较对照组和轻度OSAHS组明显增厚.血浆IL-18水平与颈动脉IMT、呼吸暂停低通气指数(AHI)呈显著正相关(r值分别为0.486、0.865,P均＜0.001),与最低脉搏氧饱和度呈显著负相关(r=-0.664,P＜0.001).CPAP治疗后OSAHS患者血浆IL-18水平明显降低,颈动脉IMT未见明显改变.结论 OSAHS患者颈动脉IMT增厚,血浆IL-18水平升高,两者密切相关.血浆IL-18水平升高与OSAHS严重程度相关,OSAHS相关炎症反应可能与动脉粥样硬化的进程相关.CPAP治疗能够改善患者AHI和最低脉搏氧饱和度,降低血浆IL-18水平.
