The advent of tyrosine kinase inhibitors (TKIs) has profoundly changed the therapeutic landscape of chronic myeloid leukemia (CML) in the chronic phase (CML-CP). Imatinib is the first-generation, and the first and as yet the most widely used TKI, and the recommended dose is 400 mg/day for treating CML-CP. Most patients tolerate this treatment well, and prolonged hematological toxicities have rarely been reported. In this manuscript, we report a newly diagnosed CML-CP patient who developed prolonged myelosuppression (lasting for more than three months) following only one week of imatinib at 400 mg/day as the solitary treatment. Imatinib was discontinued, and pancytopenia persisted, with a continuous decrease in hemoglobulin levels. After restoration of autologous hematopoiesis, reintroduction of imatinib at 100 mg/day resulted in recurrent myelosuppression, and subsequent treatment with imatinib at 50 mg/day achieved good hematological homeostasis. We hypothesized that extraordinary sensitivity resulted in severe and prolonged myelosuppression.

As severe conditions, acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) threaten human health. Inflammation and oxidative stress play a vital role in the pathogenesis of ALI/ARDS. Sphingosine kinase 1 (SphK1) significantly contributes to mediating inflammatory responses. Nevertheless, the impact of SphK1 on lipopolysaccharide (LPS)-triggered ALI/ARDS remains largely undetermined. In our current work, we explored the impact of SphK1 on ALI/ARDS using a mouse model. We studied whether it could reduce LPS-triggered inflammatory response and oxidative stress by suppressing SphK1 in ALI/ARDS. The mice were treated with the inhibitor of SphK1 (N,N-dimethylsphingosine, DMS) before intraperitoneal injection of LPS. Moreover, we assessed the survival rate, and several parameters, such as the lung wet/dry (W/D) ratio, myeloperoxidase (MPO) activity, superoxide dismutase (SOD) activity, malondialdehyde (MDA) content, and the release of inflammatory cytokines. Western blotting analysis was adopted to evaluate the levels of phosphoinositide 3-kinase (PI3K)/serine/threonine kinase (AKT) pathways. We showed that the inhibitor of SphK1 not only ameliorated LPS-stimulated lung histopathological changes and W/D ratio of lung tissue but also elevated the survival rate, the SOD activity and decreased the MDA content, MPO activity, interleukin-6 (IL-6) and tumor necrosis factor-ɑ (TNF-ɑ) production by regulating the PI3K/AKT signaling pathway in lung tissue. Taken together, SphK1 played an essential role in inflammatory responses and oxidative stress. The underlying mechanism might be linked to the activation and up-regulation of the PI3K/AKT signaling pathway in LPS-triggered ALI/ARDS.

The purpose of this study was to determine the prevalence and influencing factors of systemic lupus erythematosus (SLE) patients complicated with infection having multi-system involvement and to analyze the influencing factors of early CMV and fungal infection. We conducted a cross-sectional study of hospitalized SLE patients complicated with infection. Participants had an average age of 44.80 ± 17.30, with 152 being female (89.94%). Clinical data and laboratory results were collected from medical records. Receiver operating characteristic (ROC) curves were plotted, and sensitivity and specificity were calculated. Univariate analysis showed that systemic lupus erythematosus disease activity index-2000 (SLEDAI-2k), red blood cell, platelets, hemoglobin, lymphocytes, IgG, IgM, C3, C4, albumin and globulin were significantly associated with SLE patients with infection complicated with multi-system involvement. After multivariable analysis, the following variables remained significant: Hemoglobin, CD4 lymphocyte, IgM and SM ( p < 0.05). ROC curve analysis showed the areas under the curve of Hb, CD4 count, and IgM for the differential diagnosis of SLE with infection complicated with multisystem involvement being 0.646, 0.627, and 0.610. Then, the sensitivities of 73.3%, 53.3%, and 73.3% were observed with the specificities of 54.1%, 69.7%, and 48.6%, respectively. Our results demonstrated that hemoglobin, CD4 lymphocyte value, IgM and anti SM antibody had significant value in monitoring multi-system involvement in SLE patients complicated with infection. Besides, intrinsic lymphatic count disturbances associated with SLE disease can cause infections by opportunistic pathogens such as fungi.

Objectives: In humans, enterococci are among the most important opportunistic pathogens. This study aims to compare invasive isolates obtained from blood cultures of patients with sepsis and endocarditis with colonizing isolates obtained from healthy donors’ stool samples. Methods: A case-by-case assessment was conducted on invasive infection cases to determine whether enterococci were involved in their pathogenesis. They were tested for the presence of virulence factor genes, β-hemolysis on agars supplemented with human and sheep blood, and biofilm forming capacity. Results: Three species of enterococci were identified among invasive isolates: Enterococcus faecalis, Enterococcus faecium, and Enterococcus durans. All endocarditis isolates were biofilm producers. Genes esp, gelE, asa1, ace, hyl, cylB, and cylA were present in 7 (41.2%), 11 (64.7%), 11 (64.7%), 13 (76.5%), 0, 3 (17.6%), and 1 (5.9%) invasive isolate, but none of them could be linked to a particular infection (sepsis or endocarditis). Colonizing isolates proved to have had more virulence factor genes, but the differences were not statistically significant. Members of that group produced a greater amount of biofilm when the ace gene was absent ( p = 0.047). The production of β-hemolysis by noninvasive strains was detected more frequently when agar was supplemented with human blood ( p = 0.021). In general, the presence of either cyl gene on that specific agar was in direct connection with the production of β-hemolysis: cylA ( p = 0.047) or cylB ( p = 0.020). Conclusion: We have been unable to establish any correlation between invasive isolates and any virulence gene carriage and biofilm formation. β-hemolysis was produced significantly more often by colonizing strains when agar had been supplemented with human blood.

In recent years, studies on the structure, function, and regulation of the C/EBPε gene have become an essential topic in the field of many diseases. CCAAT/enhancer-binding protein ε (C/EBPε) is the fifth member of the transcription factor CCAAT/C/EBP family of transcription factors. It plays crucial roles in cell proliferation, differentiation, immunity, energy metabolism, and hematopoiesis. C/EBPε plays essential roles in regulating the hematopoietic system, including myeloid cell development and maturation, participation in the body’s immune responses, and prevention of infections. C/EBPε function is regulated by phosphorylation, acetylation, methylation, and other types of genes. This review related to C/EBPε structure, function and regulation provides a theoretical basis for subsequent research in this area. C/EBPε is an emerging therapeutic target and thus provides new strategies for disease prevention and control.

Pancreatic β-cells produce and secrete insulin to maintain blood glucose levels within a narrow range. Defects in the function and mass of β-cells play a significant role in the development and progression of diabetes. Increased β-cell deficiency and β-cell apoptosis are observed in the pancreatic islets of patients with type 2 diabetes. At an early stage, β-cells adapt to insulin resistance, and their insulin secretion increases, but they eventually become exhausted, and the β-cell mass decreases. Various causal factors, such as high glucose, free fatty acids, inflammatory cytokines, and islet amyloid polypeptides, contribute to the impairment of β-cell function. Therefore, the maintenance of β-cell function is a logical approach for the treatment and prevention of diabetes. In this review, we provide an overview of the role of these risk factors in pancreatic β-cell loss and the associated mechanisms. A better understanding of the molecular mechanisms underlying pancreatic β-cell loss will provide an opportunity to identify novel therapeutic targets for type 2 diabetes.

Objective: Early diagnosis and intervention of diabetic nephropathy (DN) is necessary to optimize therapy in order to delay the progression of diabetes. This research aimed to reveal the change of vascular endothelial growth factor (VEGF) and endothelin-1 (ET-1) in patients with DN, and to assess possible correlations with glycated hemoglobin (HbAlc) values. Methods: The present study was a retrospective, single-center study conducted at a teaching hospital in the northeast China. A total of 120 patients were divided into proteinuria-positive group ( n = 40), the microalbuminuria group ( n = 40), and the high proteinuria group ( n = 40) according to the urinary albumin excretion rate (UAER), and 40 healthy volunteers were selected as the control group. The levels of VEGF, ET-1 and HbA1c were measured in all subjects and principal component analysis (PCA) was performed to classify and reveal correlations between VEGF, ET-1 and HbA1c. Results: Compared to the control group, a significant difference in the increase of HbA1c was detected in group I, II and III. A significant increase in the concentrations of serum VEGF and ET-1 was also observed. HbA1c in DN patients had proven to be positively correlated with VEGF (r = 0.7941; p < 0. 0001) and ET-1 (r = 0.8504; p < 0.0001) respectively. Conclusion: The elevated levels of VEGF and ET-1 in serum have been proposed as being able to supplement the additional information about the progression of DN. These data suggest that the decrease in endothelial function may be related to poor glycemic control.

The development and progression of malignancies are closely linked to hypercoagulability. As an early type of lung adenocarcinoma, ground glass nodules (GGNs) have been detected increasingly. Blood Maximum amplitude (MA) and mean platelet volume (MPV) are related to various conditions of hypercoagulability. Therefore, the role of MA and MPV in diagnosing lung adenocarcinoma cancer featured with GGNs was investigated in this case-control study. The analyzed data of this study is derived from GGNs patients and healthy individuals in West China (Airport) Hospital Sichuan University. The differences between GGNs patients and healthy individuals were determined by one-way ANOVA, logistic regression or chi-squared test. The accuracy of diagnostic was performed by receiver operating characteristic curve (ROC). The relative mRNA expressions were studied by RT-qPCR. 470 patients diagnosed with GGNs which benign lesions (BN group) are inflammatory and malignant lesions (LC group) are adenocarcinoma in stage IA, and 235 healthy subjects (HC group) were enrolled in this study. Levels of MA and MPV were increased in LC group compared with BN and HC group ( p < 0.001, p < 0.001). When we combined MA and MPV, MA and MPV presented a sensitivity (SEN) of 0.809 and a specificity (SPE) of 0.774. And the area under the curve (AUC) increased to 0.871 (0.837–0.900) when confidence interval was 95%. This study demonstrates that there have been systemic changes in coagulation disorders in the pathogenesis of GGNs. The diagnostic ability to different lung adenocarcinoma cancer featured with GGNs from benign or healthy controls can be improved by the combination of MA and MPV. Maximum amplitude and MPV may be used as biomarkers to detect lung adenocarcinoma cancer featured with GGNs.
恶性肿瘤的发生和发展与高凝性密切相关。作为肺腺癌的早期类型，磨玻璃结节(ggn)越来越多地被发现。血液最大振幅(MA)和平均血小板体积(MPV)与各种高凝状态有关。因此，本病例对照研究探讨了MA和MPV在诊断以ggn为特征的肺腺癌中的作用。本研究的分析数据来源于四川大学华西(机场)医院的ggn患者和健康人群。ggn患者与健康个体的差异采用单因素方差分析、logistic回归或卡方检验。采用受试者工作特征曲线(ROC)评价诊断的准确性。RT-qPCR检测相对mRNA表达量。本研究纳入470例诊断为ggn的患者，其中良性病变(BN组)为炎症，恶性病变(LC组)为IA期腺癌，健康受试者(HC组)235例。LC组MA、MPV水平较BN、HC组升高(p < 0.001, p < 0.001)。当我们将MA和MPV结合使用时，MA和MPV的敏感性(SEN)为0.809，特异性(SPE)为0.774。当置信区间为95%时，曲线下面积(AUC)增加至0.871(0.837 ~ 0.900)。本研究表明，凝血功能障碍在ggn发病机制中发生了全身性变化。MA和MPV联合检测可提高对不同类型肺腺癌的诊断能力。最大振幅和MPV可作为检测以ggn为特征的肺腺癌的生物标志物。

The relative mRNA expressions were studied by RT-qPCR. 470 patients diagnosed with GGNs which benign lesions (BN group) are inflammatory and malignant lesions (LC group) are adenocarcinoma in stage IA, and 235 healthy subjects (HC group) were enrolled in this study. Levels of MA and MPV were increased in LC group compared with BN and HC group ( p < 0.001, p < 0.001). When we combined MA and MPV, MA and MPV presented a sensitivity (SEN) of 0.809 and a specificity (SPE) of 0.774. And the area under the curve (AUC) increased to 0.871 (0.837–0.900) when confidence interval was 95%. This study demonstrates that there have been systemic changes in coagulation disorders in the pathogenesis of GGNs. The diagnostic ability to different lung adenocarcinoma cancer featured with GGNs from benign or healthy controls can be improved by the combination of MA and MPV. Maximum amplitude and MPV may be used as biomarkers to detect lung adenocarcinoma cancer featured with GGNs.","PeriodicalId":55162,"journal":{"name":"European Journal of Inflammation","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45526267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To conduct a systematic review and meta-analysis to compare the effects of statins and placebo on systolic blood pressure (SBP) and diastolic blood pressure (DBP) in patients with hypertension. We used different databases such as MEDLINE and the Cochrane Library Central Register of Controlled Trials (CENTRAL) to search for randomized controlled trials published from 1 January 2000 to 1 January 2022 to retrieve relevant studies and full-text articles evaluating statins versus placebo in patients with hypertension. Data were taken from eligible studies. The included articles also performed Cochran’s Q statistics, forest plots, funnel plots, Egger’s test, and sensitivity analyses. This study included 8 studies with a total of 3086 patients. We sought to assess patients' SBP and DBP. The results were expressed as mean differences (MD) with 95% confidence intervals. There was no difference in DBP between the statin and placebo groups (MD = 2.48, 95% CI [−2.00, 6.96], p = .28, random effects model). In terms of SBP, the statin group was superior to the placebo group (MD = 4.37, 95% CI [0.72, 8.02], p = .02, random-effects model). Sensitivity analyses and funnel plots showed that our study was robust, with low publication bias. The results show that statins could be clinically more effective than placebo in patients with hypertension.
进行系统综述和荟萃分析，比较他汀类药物和安慰剂对高血压患者收缩压（SBP）和舒张压（DBP）的影响。我们使用MEDLINE和Cochrane Library Central Register of Controlled Trials（Central）等不同数据库搜索2000年1月1日至2022年1月31日发表的随机对照试验，以检索评估高血压患者他汀类药物与安慰剂的相关研究和全文文章。数据取自符合条件的研究。纳入的文章还进行了Cochran的Q统计、森林图、漏斗图、Egger检验和敏感性分析。本研究包括8项研究，共3086名患者。我们试图评估患者的收缩压和舒张压。结果用95%置信区间的平均差（MD）表示。他汀类药物组和安慰剂组之间的DBP没有差异（MD=2.48，95%CI[-2.00，6.96]，p=.28，随机效应模型）。就SBP而言，他汀类药物组优于安慰剂组（MD=4.37，95%CI[0.72，8.02]，p=0.02，随机效应模型）。敏感性分析和漏斗图显示，我们的研究是稳健的，发表偏倚低。研究结果表明，他汀类药物在高血压患者中的临床疗效可能比安慰剂更高。

Background: Hyperglycemic patients are at a high risk of COVID-19 severity. Neutrophils have been considered critical effector cells in COVID-19 development. Vitamin D deficiency is prevalent in hyperglycemic patients and was found to adversely associate with the neutrophil count. Aim: The goal of this work was to evaluate the characteristics of diabetic and pre-diabetic COVID-19 patients and discovered changes in neutrophils and their correlation, if any, with disease clinical presentation. Patients and Methods: The study included total of (514) Covid-19 positive patients confirmed by PCR and recruited from the Prince Mohammad Bin Abdulaziz Hospital in Riyadh, Saudi Arabia. Patient’s clinical characteristics were collected for all patients. Laboratory tests include HbA1c, neutrophil count, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), ferritin, D- dimer, 25 hydroxy vitamin D (25(OH)D), and folate. Results: The results found that 286 patients (55.6%) were diabetic, 77 patients (15%) were pre-diabetic and 151 (29.4%) were normoglycaemic. A significant difference was exhibited regarding the neutrophil count and inflammatory factors of COVID-19 severity. Furthermore, the neutrophil count was found to be directly correlated with the severity monitoring biochemical markers for Covid-19: CRP, ESR, ferritin, and D-dimer and inversely associated with vitamin D levels in diabetic and pre-diabetic patients. Conclusion: Our findings highlight the change of neutrophils in COVID-19 diabetic and pre-diabetic patients that was found to correlate positively with CRP, ESR, ferritin, and D-dimer, and negatively with 25(OH)D, but their correlation with the clinical presentation of the disease need further large investigations.
