Mouse C-reactive protein and endotoxin-induced resistance

Patterson, L. T. (University of Texas, Galveston), and R. D. Higginbotham. Mouse C-reactive protein and endotoxin-induced resistance. J. Bacteriol. 90:1520-1524. 1965.-The relationship between the level of C-reactive protein (CRP) in the sera of mice and resistance to Staphylococcus aureus infection after the injection of Escherichia coli endotoxin was studied. The CRP level was essentially unchanged at 6 hr after endotoxin, and resistance was slightly decreased. At 24 hr after endotoxin, both CRP levels and resistance were increased. Since the increase in the CRP level and resistance appeared to be associated, it was of interest that, when mouse CRP was tested for in vitro reactions with several strains of bacteria, cells of all species of gram-positive bacteria tested (including S. aureus) were agglutinated by CRP. E. coli was not agglutinated under the conditions of the test. It is proposed that mouse CRP is an opsonin, and possibly a lysin, and is involved in nonspecific resistance to infection with S. aureus.     

Changes of C-reactive protein levels in rainbow trout (Oncorhynchus mykiss) sera after exposure to anti-ectoparasitic chemicals used in aquaculture

Changes of serum C-reactive protein (CRP) levels in rainbow trout (Oncorhynchus mykiss) were studied after exposure to formalin, metriphonate or potassium permanganate, which are used in aquaculture as anti-ectoparasitic chemicals. The CRP level in normal trout sera is 88+/-5 microg ml(-1) according to sandwich enzyme-linked immunosorbent assay. CRP levels increased to a maximum at six or nine days after exposure to formalin for 3.5 h at 300 ppm or 9.5 h at 30 ppm, respectively; these levels are 4.3 and 18 times higher than normal. At 18 days after treatment, the CRP level had decreased to significantly below the normal level. After exposure to metriphonate (0.4 ppm for 30 min), the CRP level increased significantly to a maximum at three days after exposure (9.9 times higher than normal), then decreased to below normal. With exposure to potassium permanganate at 40 ppm for 45 min, fish showed significantly lower CRP levels than the normal level at 14 days after exposure. Fish reared at a water temperature of 16.5-19.5 degrees C showed significantly higher CRP levels than those reared at 13 degrees C. Measurement of CRP levels in trout serum can be used as a bioindicator of the health condition of the fish.     

Changing patterns of serum and bile antibodies in re-infected rats with Clonorchis sinensis

Rats develop strong resistance to re-infection and super-infection by Clonorchis sinensis. The present study investigated the antibodies present in the sera and bile juice of rats that were primary infected and re-infected with C. sinensis. The serum level of specific IgG antibodies, which were elevated 2 wk of the primary infection, peaked at 4 wk and subsequently remained unchanged even during re-infection. The total IgE level in serum increased slowly from 388 ng / ml to 3,426 ng / ml beginning 2 wk after the primary infection, and remained high up to 8 wk but dropped to a normal level (259 ng / ml) after treatment. In resistant re-infected rats, the serum IgE level increased rapidly and peaked within 1 wk, whereas no increase was observed in immunosuppressed rats. The serum level of specific IgA antibodies was elevated beginning 1 wk after infection, and decreased 4 wk after treatment. The total bile IgA level unchanged during the primary infection but increased in treated and re-infected rats. The elevated levels of serum IgE and bile IgA indicate that these immunoglobulins may be correlated with the development of resistance to re-infection by C. sinensis in rats.     

Levels of soluble ICAM-1 in premature and full-term neonates with infection

BACKGROUND: Infection in the neonatal period is an extremely serious condition and diagnosis is difficult. C-reactive protein (CRP) is widely used as a marker of infection; however, its usefulness is limited in the early phase. The role of soluble intracellular adhesion molecule-1 (sICAM-1), an adhesion molecule, has been examined in recent studies as an early marker of neonatal infection with controversial results. AIM: Assessment of sICAM-1 concentrations and correlation with CRP, which is the currently used marker of infection, in order to use sICAM as an early diagnostic tool in neonates suspected for infection METHODS: Blood samples and blood cultures were obtained from two groups of pre-term and full-term neonates with clinical suspicion of infection prior to the initiation of antibiotics. The sICAM-1 and CRP values were compared with the corresponding noninfected ones (n = 10 each). RESULTS: The sICAM-1 levels were found increased in the group of both premature and term neonates with infection compared with the corresponding healthy ones (P < 0.0001). Prematurity combined with infection resulted in excessive increase of the levels of sICAM-1 in comparison with full-term infected newborns (p < 0.001). CRP values were normal in all samples except one in both full-term and premature infected neonates on day 1 of clinically suspected infection. Serial detection of CRP values on days 2 and 4 of infection revealed a pattern according to which CRP values in premature neonates continued rising, while in the group of full terms these values, after rising on the second day, lowered on day 4. CONCLUSIONS: Increased sICAM-1 levels can be detected early in both full-term and premature neonates with sepsis while CRP levels are within normal range at the same time. Assessment of sICAM-1 concentrations may be used as a diagnostic tool in neonates suspected for infection, resulting in earlier initiation of antibiotic therapy and therefore improving their outcome.     

Serum C-reactive protein (CRP) levels and insulin resistance in non-obese women with polycystic ovarian syndrome, and effect of bicalutamide on hirsutism, CRP levels and insulin resistance

BACKGROUND/AIMS: Insulin resistance is associated with serum C-reactive protein (CRP) levels. We aimed to evaluate the effect of bicalutamide on insulin resistance and serum CRP levels in non-obese polycystic ovarian syndrome (PCOS) patients. METHODS: 40 non-obese patients (BMI < or =25 kg/m2) with PCOS and, 40 age- and BMI-matched healthy women were studied. Patients received bicalutamide orally at the dose of 25 mg/day. Serum CRP levels were measured with immunometric assay. Homeostasis model assessment (HOMA-IR) index was used for insulin resistance. RESULTS: Mean Ferriman-Gallwey score (FGS) (p = 0.001), insulin (p = 0.001), serum glucose (p = 0.001), prolactin (p < 0.003), total (p < 0.04) and free testosterone (p = 0.001) and free androgen index (FAI) levels (p = 0.001) of PCOS subjects were higher than in the control group. Mean HOMA-IR of PCOS patients was higher than in control subjects (2.43 +/- 1.2 and 0.94 +/- 0.37, p = 0.001). CRP levels in subjects with PCOS was also higher than in control subjects (4.27 +/- 1.33 and 0.98 +/- 0.19, p = 0.001). After bicalutamide treatment, FGS, free and total testosterone and FAI decreased (p = 0.001). HOMA-IR, prolactin and CRP levels did not show any statistical difference with bicalutamide treatment. CONCLUSIONS: PCOS patients had insulin resistance and a high CRP level. Bicalutamide treatment did not influence insulin resistance and CRP level in PCOS, and this ineffectiveness of bicalutamide on CRP levels may be the result of insulin resistance and/or high prolactin levels at this time.     

Characteristics of Serum Endocan Levels in Infection

Objectives

Endocan is a newly recognized biomarker of sepsis. However, there have been no studies of the trends in endocan levels during infection and their associations with other clinical factors. The aim of this study was to assess the time course of endocan levels and the associations of endocan with clinical factors during infection by comparison with other biomarkers.

Methods

Serum samples and blood cultures were obtained from patients who were diagnosed with infection from June 2013 to March 2014. Serum endocan, C-reactive protein (CRP), and procalcitonin (PCT) levels during four periods during infection were measured (day 0, day 1-2, day 3-5, and day 6-10).

Results

A total of 78 patients were enrolled in this study. The median endocan level decreased by only 23% during infection, whereas both serum CRP and PCT levels decreased by more than 80%. Endocan levels were correlated to neither CRP levels nor PCT levels in each period. Endocan levels at day 0 in patients with bacteremia were higher than those without bacteremia (1.09 ng/mL vs 0.82 ng/mL, P=0.002), but neither CRP levels nor PCT levels at day 0 were different between the two groups. Areas under the receiver operator characteristic (ROC) curves of endocan, CRP, and PCT at day 0 were 0.662, 0.343, and 0.563, respectively. Positive blood cultures tended to be related to high endocan levels, but not significantly (odds ratio: 4.24, 95% CI: 0.99-10.34, P=0.05).

Conclusions

In bacteremic cases, serum endocan levels in bacteremia tended to be higher than in non-bacteremic cases. Although endocan level was not identified as a prognostic factor of bacteremia, further prospective study concerning the relationship between serum endocan level and bacteremia would be needed.     

Resistin and adiponectin levels in subjects with coronary artery disease and type 2 diabetes

BACKGROUND: Resistin and adiponectin are implicated in insulin resistance and atherosclerosis. The objective of this study was to evaluate the association between plasma resistin levels and the presence of coronary artery disease (CAD) or diabetes compared to the controls. In a cross-sectional study, we measured glucose, fasting lipid panel, resistin, adiponectin, insulin, C-reactive protein (CRP) and TNF-alpha in 57 subjects with CAD, 58 subjects with diabetes compared to 45 normal control subjects. Results: Subjects with CAD compared to the control subjects had increased insulin resistance index (39+/-32 vs. 13.45+/-12.73 with p<0.0001), CRP levels (3.8+/-4.03 vs. 2.0+/-2.0 with p<0.05) and decreased levels of adiponectin (12.5+/-4.8 vs. 17.26+/-10.4 with p<0.0003). Subjects with diabetes compared to the controls had had increased insulin resistance index (69+/-19 vs. 13.45+/-12.73 with p<0.001), CRP levels (4.1+/-4.8 vs. 2.0+/-2.0 with p<0.01) and decreased levels of adiponectin (11.58+/-4.8 vs. 17.26+/-10.4 with p<0.001). Compared to the controls, there was no significant difference in the levels of resistin in subjects with CAD (4.92+/-3.2 vs. 4.1+/-2.4) as well as diabetes (4.92+/-3.2 vs. 4.6+/-2.6). Both CRP and resistin levels correlate with TNF-alpha (r=0.557, p<0.000001; r=0.84, p<0.000001). Conclusions: The present study shows decreased plasma adiponectin levels in subjects with diabetes as well as in subjects with CAD is similar to the literature. Plasma levels of resistin in subjects with CAD or diabetes are similar to the controls. However, there was a strong correlation of resistin levels with inflammatory markers. This suggests resistin as an inflammatory marker associated with CAD.

An evaluation of purification methods for baculoviruses

In Biomphalaria glabrata parasitized by Schistosoma mansoni there was an increase in relative weight of the digestive gland-gonad complex and a decrease in glycogen in that complex and in the remainder of the carcass by day 25. Glycogen levels further decreased close to zero and remained at this low level for the duration of the experiment. Relative weight of the digestive gland-gonad reached a peak at day 30 and decreased toward normal by day 40. Galactogen levels in the albumen gland, although decreased slightly, were not significantly lower than in normal snails. In starved snails, glycogen and galactogen decreased significantly below normal at day 21 and remained at a low level until the experiment ended. This study raises the possibility that starvation of the host by the parasite may play a significant role in the pathology observed in this infection.

动态监测C-反应蛋白及降钙素原在创伤后脓毒血症中的价值

目的探讨C-反应蛋白及降钙素原在创伤后脓毒血症中的动态变化及对预后的评估价值。方法选择诸暨市中心医院创伤后脓毒血症患者78例作为研究对象,比较脓毒血症组与对照组之间血清CRP及PCT水平的差异。根据脓毒血症的不同程度将入选的创伤后脓毒血症病例分为单纯脓毒血症、脓毒血症合并器官功能衰竭及感染性休克组,比较三组患者血清CRP水平、血清PCT水平及APACHE-Ⅱ评分的差异。根据不同的随访结果将脓毒血症患者分为好转、无效及病死组,比较三组入选当日、入选后第3、5天血清CRP及PCT水平的变化。结果入选当日,脓毒血症组患者血清CRP及PCT水平均明显高于对照组,差异具有统计学意义(t=68.472、40.243,P0.01)。不同程度脓毒血症组患者血清CRP、PCT水平及APACHE-Ⅱ评分均不完全相同(F=3.804、8.292、5.273,P0.05),单纯脓毒血症及脓毒血症合并器官功能衰竭组在血清CRP水平上差异无统计学意义(P0.05),其余两组间比较差异均有统计学意义(P0.05);脓毒血症患者中,好转组入选后第5天血清CRP水平较入选当日及第3天降低(P0.05),但入选当日及第3天CRP水平差异无统计学意义(P0.05);血清PCT水平入选当日、入选后第3天、第5天呈逐渐下降趋势,组间比较差异均有统计学意义(P0.05)。病死组患者血清CRP水平入选当日、入选后第3天、第5天均差异无统计学意义(P0.05),而血清PCT水平呈递增趋势,组间比较差异均有统计学意义(P0.05)。无效组血清CRP及PCT水平入选当日、入选后第3天、第5天差异均无统计学意义(P0.05)。结论血清CRP及PCT水平均能反应创伤后脓毒血症的感染状态,但在评估病情及预后方面,血清PCT更具有优势。     

Monocyte chemoattractant protein-1-dependent increase of V alpha 14 NKT cells in lungs and their roles in Th1 response and host defense in cryptococcal infection.

To elucidate the role of NKT cells in the host defense to cryptococcal infection, we examined the proportion of these cells, identified by the expression of CD3 and NK1.1, in lungs after intratracheal infection with Cryptococcus neoformans. This population increased on day 3 after infection, reached a peak level on days 6-7, and decreased thereafter. In Valpha14 NKT cell-deficient mice, such increase was significantly attenuated. The proportion of Valpha14 NKT cells, detected by binding to alpha-galactosylceramide-loaded CD1d tetramer, and the expression of Valpha14 mRNA increased after infection with a similar kinetics. The delayed-type hypersensitivity response and differentiation of the fungus-specific Th1 cells was reduced in Valpha14 NKT cell-deficient mice, compared with control mice. Additionally, elimination of this fungal pathogen from lungs was significantly delayed in Valpha14 NKT cell-deficient mice. Production of monocyte chemoattractant protein (MCP)-1 in lungs, detected at both mRNA and protein levels, increased on day 1, reached a peak level on day 3, and decreased thereafter, which preceded the increase in NKT cells. Finally, the increase of total and Valpha14(+) subset of NKT cells after infection was significantly reduced in MCP-1-deficient mice. Our results demonstrated that NKT cells, especially Valpha14(+) subset, accumulated in a MCP-1-dependent manner in the lungs after infection with C. neoformans and played an important role in the development of Th1 response and host resistance to this fungal pathogen.     

血清降钙素原检测对早期诊断肝衰竭合并感染的临床意义

目的:探讨血清降钙素原(PCT)检测在肝衰竭合并感染早期诊断中的临床意义。方法:选择2014年3月至2017年3月我院收治的由病毒性肝炎导致的肝衰竭患者102例为研究对象,根据有无感染分为感染组(75例)和非感染组(27例),采用干式免疫荧光法检测其血清PCT水平,并检测两组患者白细胞(WBC)水平、C反应蛋白(CRP)水平、中性粒细胞百分比(N%),进行全身炎症反应综合征(SIRS)评分,采用多因素Logistic回归模型分析PCT、WBC、CRP、N%水平和SIRS评分对肝衰竭合并感染的预测价值大小,绘制受试者工作特征曲线(ROC曲线)评价PCT、WBC、CRP、N%水平和SIRS评分对肝衰竭合并感染的诊断价值。结果:感染组PCT、WBC、N%、CRP水平和SIRS评分均高于非感染组(P0.05);不同感染部位患者WBC、N%、CRP水平和SIRS评分比较差异不明显(P0.05);多部位感染患者血清PCT水平均高于其他单部位感染患者(P0.05);多因素Logistic回归分析显示,PCT和N%水平是肝衰竭合并感染的独立危险因素(P0.05);PCT、N%、CRP、WBC水平和SIRS评分诊断肝衰竭合并感染的ROC曲线下面积(AUC)值依次为0.916、0.763、0.752、0.746、0.682,PCT诊断肝衰竭合并感染的AUC值分别与N%、CRP、WBC和SIRS评分比较差异均有统计学意义(Z=3.518、3.672、4.103、5.106,P0.05)。结论:肝衰竭合并感染患者血清PCT水平明显升高,PCT对肝衰竭合并感染的诊断价值优于WBC、CRP、N%和SIRS评分等传统实验室指标。

TNF inhibitor suppresses bone metastasis in a breast cancer cell line

C-reactive protein (CRP) is one of the most important biomarker for cardiovascular diseases. Recent studies have shown that CRP affects cell survival, differentiation and apoptosis. However, the effect of CRP on the cell cycle has not been studied yet. We investigated the cell cycle alterations and cellular mechanisms induced by CRP in H9c2 cardiac myocytes. Flow cytometry analysis showed that CRP-treated H9c2 cells displayed cell cycle arrest in G0/G1 phase. CRP treatment resulted in a significant reduction in the levels of CDK4, CDK6 and cyclin D1 in a concentration-dependent manner. Interestingly, CRP caused an increase in the p53 accumulation and its phosphorylation on Ser15, leading to induce p21 upregulation. Treatment with a specific p53 inhibitor, PFT-α restored the levels of CDK4 and CDK6. A significant increase of ERK1/2 phosphorylation level was detected in CRP-treated cells. Furthermore, pretreatment of a specific ERK inhibitor resulted in decreased p53 phosphorylation and p21 induction. ERK inhibitor pretreatment induced significant restoration of protein levels of CDK4 and CDK6, leading to re-entry into the cell cycle. In addition, increased phosphorylation of p53 and ERK induced by CRP was considerably reversed by Fc gamma receptor IIIa (FcγRIIIa) knock-down using siRNA. FcγRIIIa siRNA transfection also restored the levels of cell cycle proteins. Our study has provided the first proposal on the novel insights into how CRP directly affects cell cycle in cells.     

Serum protein profile of mice during infection with of Ancylostoma caninum and after the administration of tetramisole and levamisole

Serum protein changes in mice following Ancylostoma caninum larval infection were observed as decrease in albumin, gamma globulin and increase in beta globulin. These serum protein components showed a tendency to return back to their normal levels after the administration of effective anthelmintic such as tetramisole or levamisole to the infected mice. The increased level of beta globulin after treatment although decreased but did not return to its normal level within 14 days observation period.     

急性肺炎支原体感染儿童白细胞和C反应蛋白的变化及其临床意义

目的：探讨急性肺炎支原体感染后儿童白细胞及CRP变化的规律,为该病的临床治疗与诊断提供参考。方法：对65例急性肺炎支原体感染儿童和同期65例健康儿童的血常规白细胞和CRP检测结果采用t检验进行统计比较,分析二者的差异。结果：与同期健康儿童相比,急性肺炎支原体感染儿童白细胞计数增高,中性粒细胞比例及绝对值增高,淋巴细胞比例及绝对值下降,嗜酸性粒细胞、嗜碱性粒细胞及单核细胞比例及绝对值均无明显变化,CRP水平明显升高。结论：急性肺炎支原体感染儿童通过白细胞、CRP的变化可以初步判断。
